203,383 | <p>I get obsessed with the best names for arrays and variables that I use, I'll look up words in the thesaurus, dictionary, etc..</p>
<p>So I'm trying to name this array / structure:</p>
<pre><code>$nameMe = array(
'392' => TRUE,
'234' => TRUE,
'754' => TRUE,
'464' => TRUE,
);
</code></pre>
<p>and it's used to check if that id has a certain property, like so</p>
<pre><code>if(isset($name[$id])) {
doSomething();
}
</code></pre>
<p>Problem being I'm getting really long variable names like</p>
<pre><code>$propertyNameArrayIdIndexed
</code></pre>
<p>Any ideas for how I can better name this particular function of array? or better names in general</p>

203,384 | <p>Various programs can do stuff only when you haven't used the computer for a while (eg screensaver, Google Desktop indexing, etc).</p>
<p>How do they know when it has been inactive? Is there some function in Windows that tells you how long it has been inactive, or do you have to use some kind of keyboard/mouse hook to track activity yourself?</p>
<p>I'm using C#, but I'm interested in any method of determining the inactivity.</p>

203,397 | <p>Is there a way to change the context sensitive help in Visual Studio so that it will only search against the text under the caret instead of a compilation error in your code?</p>
<p>More info:
After you compile and receive a compilation error(underlined), placing the caret within the underlined text and pressing <kbd>F1</kbd> will take you to the Compilation error page instead of the help for the function under the caret.
Can this behavior be changed to always go to the method/keyword help?</p>

203,399 | <p>I'm running a MySQL database locally for development, but deploying to Heroku which uses Postgres. Heroku handles almost everything, but my case-insensitive Like statements become case sensitive. I could use iLike statements, but my local MySQL database can't handle that.</p>
<p>What is the best way to write a case insensitive query that is compatible with both MySQL and Postgres? Or do I need to write separate Like and iLike statements depending on the DB my app is talking to?</p>

203,425 | <p>What's the ASP equivalent to PHP's <code>.=</code> when concatenating strings? I'm referring to asp NOT asp.net.</p>
<p>I meant to specify that I'm in a for-loop. So I want to know the equivalent for <code>.=</code> (in php) not standard concatenation.</p>
<p><em>Example:</em></p>
<pre><code>For Each Item In Request.Form
If (Item = "service") then
For x=1 To Request.Form(item).Count
service = "&service="&Request.Form(Item)(x)
Next
End If
Next

203,446 | <p>Does anyone know the format of the MAPI property <code>PR_SEARCH_KEY</code>?</p>
<p>The <a href="http://msdn.microsoft.com/en-us/library/ms529414(EXCHG.10).aspx" rel="nofollow noreferrer">online documentation</a> has this to say about it:</p>
<blockquote>
<p>The search key is formed by
concatenating the address type (in
uppercase characters), the colon
character ':', the e-mail address in
canonical form, and the terminating
null character.</p>
</blockquote>
<p>And the exchange document <a href="http://msdn.microsoft.com/en-us/library/cc433489(EXCHG.80).aspx" rel="nofollow noreferrer">MS-OXOABK</a> says this:</p>
<blockquote>
<p>The PidTagSearchKey property of type
PtypBinary is a binary value formed by
concatenating the ASCII string "EX: "
followed by the DN for the object
converted to all upper case, followed
by a zero byte value.</p>
</blockquote>
<p>However all the MAPI messages I've seen with this property have it as some sort of binary 16 byte sequence that looks like a GUID. Does anyone else have any more information about it? Is it always 16 bytes?</p>
<p>Thanks!</p>

203,468 | <p>Ok, so I'm looking for a bit of architecture guidance, my team is getting a chance to re-cast certain decisions with a new feature that we're building, and I wanted to see what SO thought :-) There are of course certain things that we're not changing, so the solution would have to fit in this model. Namely, that we've got an ASP.NET application, which uses web services to allow users to perform actions on the system.</p>
<p>The problem comes in because, as with many systems, different users need access to different functions. Some roles have access to Y button, and others have access to Y and B button, while another still only has access to B. Most of the time that I see this, developers just put in a mish-mosh of if statements to deal with the UI state. My fear is that left unchecked, this will become an unmaintainable mess, because in addition to putting authorization logic in the GUI, it needs to be put in the web services (which are called via ajax) to ensure that only authorized users call certain methods.</p>
<p>so my question to you is, how can a system be designed to decrease the random ad-hoc if statements here and there that check for specific roles, which could be re-used in both GUI/webform code, and web service code.</p>
<p>Just for clarity, this is an ASP.NET web application, using webforms, and <a href="http://projects.nikhilk.net/ScriptSharp/" rel="nofollow noreferrer">Script#</a> for the AJAX functionality. Don't let the script# throw you off of answering, it's not fundamentally different than asp.net ajax :-)</p>

203,475 | <p>In my code, I am creating a collection of objects which will be accessed by various threads in a fashion that is only safe if the objects are immutable. When an attempt is made to insert a new object into my collection, I want to test to see if it is immutable (if not, I'll throw an exception).</p>
<p>One thing I can do is to check a few well-known immutable types:</p>
<pre><code>private static final Set<Class> knownImmutables = new HashSet<Class>(Arrays.asList(
String.class, Byte.class, Short.class, Integer.class, Long.class,
Float.class, Double.class, Boolean.class, BigInteger.class, BigDecimal.class
));
...
public static boolean isImmutable(Object o) {
return knownImmutables.contains(o.getClass());
}
</code></pre>
<p>This actually gets me 90% of the way, but sometimes my users will want to create simple immutable types of their own:</p>
<pre><code>public class ImmutableRectangle {
private final int width;
private final int height;
public ImmutableRectangle(int width, int height) {
this.width = width;
this.height = height;
}
public int getWidth() { return width; }
public int getHeight() { return height; }
}
</code></pre>
<p>Is there some way (perhaps using reflection) that I could reliably detect whether a class is immutable? False positives (thinking it's immutable when it isn't) are not acceptable but false negatives (thinking it's mutable when it isn't) are.</p>
<p><strong>Edited to add:</strong> Thanks for the insightful and helpful answers. As some of the answers pointed out, I neglected to define my security objectives. The threat here is clueless developers -- this is a piece of framework code that will be used by large numbers of people who know next-to-nothing about threading and won't be reading the documentation. I do NOT need to defend against malicious developers -- anyone clever enough to <a href="http://directwebremoting.org/blog/joe/2005/05/26/1117108773674.html" rel="noreferrer">mutate a String</a> or perform other shenanigans will also be smart enough to know it's not safe in this case. Static analysis of the codebase IS an option, so long as it is automated, but code reviews cannot be counted on because there is no guarantee every review will have threading-savvy reviewers.</p>

203,477 | <p>I'm using KML and the GGeoXml object to overlay some shapes on an embedded Google map. The placemarks in the KML file have some custom descriptive information that shows up in the balloons.</p>
<pre><code><Placemark>
<name />
<description>
<![CDATA[
<div class="MapPopup">
<h6>Concession</h6>
<h4>~Name~</h4>
<p>Description goes here</p>
<a class="Button GoRight FloatRight" href="#"><span></span>View details</a>
</div>
]]>
</description>
<styleUrl>#masterPolyStyle</styleUrl>
...Placemarks go here ...
</Placemark>
</code></pre>
<p>So far so good - the popups show up and have the correct text in them. Here's the weird thing: I'm trying to use CSS to format what goes in the popups, and it halfway works.</p>
<p>Specifically:</p>
<ul>
<li><p>The <code><h6></code> and <code><h4></code> elements are rendered using the colors and background images I've specified in my stylesheet.</p>
</li>
<li><p>Everything shows up in Arial, not in the font I've specified in my CSS.</p>
</li>
<li><p>The class names seem to be ignored (e.g. none of the <code>a.Button</code> formatting is applied; if I define a style like the one below, it's ignored.)</p>
<pre><code> div.MapPopup { background:pink; }
</code></pre>
</li>
</ul>
<p>Any ideas? I wouldn't have been surprised for the CSS not to work at all, but it's weird that it only partly works.</p>
<h3>Update</h3>
<p>Here's a screenshot to better illustrate this. I've reproduced the <code><div class="MapPopup"></code> markup further down on the page (in yellow), to show how it should be rendered according to my CSS.</p>

203,493 | <p>I know that it <em>does</em> consider ' ' as <code>NULL</code>, but that doesn't do much to tell me <em>why</em> this is the case. As I understand the SQL specifications, ' ' is not the same as <code>NULL</code> -- one is a valid datum, and the other is indicating the absence of that same information.</p>
<p>Feel free to speculate, but please indicate if that's the case. If there's anyone from Oracle who can comment on it, that'd be fantastic!</p>

203,520 | <p>I have what must be a typical catch-22 problem. I have a .NET WinForm control that contains a textbox and a checkbox. Both controls are data bound to properties on a data class instance. The textbox is for price, the check box to indicate that the price is a price override. Also on the data class is a property that holds the item's original price.</p>
<p>I would like the controls to respect the following rules:</p>
<ul>
<li>When the user enters a value into the price textbox, the checkbox is automatically checked to indicate they are overriding the price value</li>
<li>When the check box is un-checked, the item's price is restored to the original price.</li>
</ul>
<p>When the user unchecks the checkbox, the event handler tests the checked state, and sets the item's price property to the original price value. However, the price value being databound, a bind event is fired, which updates the textbox value, which fires the text changed event handler which re-checks the checkbox. </p>
<p>I've attempted to trap the conditions where I'm explicitly updating something that would trigger a control change event. This only works for part of it though. The textbox change event fires other times that are outside my control, such as when databinding fires when the form is initially shown.</p>
<p>I've been searching around and I guess I'm just not coming up with the right search terms to find what I'm looking for. It seems that databinding is all wonderful and nifty until you need to do something pratical with it, like having two bound controls interact with each other. There just doesn't seem to be a way to discriminate between what triggered the control events.</p>
<p>I've also looked at the events available on the binding source component but there doesn't seem to be anything there that is any more useful. I can handle the event that fires after binding is complete, but that's after the problems occur.</p>
<p>Anyone have any suggestions?</p>

<p>My code does not make any direct calls to setFont:. However, this would be the point in the program's execution where some buttons are made visible for the first time.</p>
<p>I've Googled. A few people with similar problems say that this gets magically fixed when they edit the NIB, or change their time zone, or other weirdness.</p>
<p>Any ideas what the real cause is?</p>
<p>(Please no whining about NDA's.)</p>
<hr>
<p><strong>Update:</strong> If I change the font of some of my buttons from "TimesNewRomanPS-BoldMT" to "Times", then the assertion failure no longer occurs. But why can't I use the desired font, which exists on the iPhone, is installed on the new machine, and is selectable in Interface Builder?</p>

203,605 | <p>I'm looking for a way to match only fully composed characters in a Unicode string.</p>
<p>Is <code>[:print:]</code> dependent upon locale in any regular expression implementation that incorporates this character class? For example, will it match Japanese character 'あ', since it is not a control character, or is <code>[:print:]</code> always going to be ASCII codes 0x20 to 0x7E?</p>
<p>Is there any character class, including Perl REs, that can be used to match anything other than a control character? If <code>[:print:]</code> includes only characters in ASCII range I would assume <code>[:cntrl:]</code> does too.</p>

203,616 | <p>The <a href="http://www.cplusplus.com/doc/tutorial/inheritance/" rel="noreferrer">C++ friend keyword</a> allows a <code>class A</code> to designate <code>class B</code> as its friend. This allows <code>Class B</code> to access the <code>private</code>/<code>protected</code> members of <code>class A</code>.</p>
<p>I've never read anything as to why this was left out of C# (and VB.NET). Most answers to this <a href="https://stackoverflow.com/questions/17434/when-should-you-use-friend-in-c">earlier StackOverflow question</a> seem to be saying it is a useful part of C++ and there are good reasons to use it. In my experience I'd have to agree.</p>
<p>Another <a href="https://stackoverflow.com/questions/200079/inheritance-trees-and-protected-constructors-in-c#200117">question</a> seems to me to be really asking how to do something similar to <code>friend</code> in a C# application. While the answers generally revolve around nested classes, it doesn't seem quite as elegant as using the <code>friend</code> keyword.</p>
<p>The original <a href="https://rads.stackoverflow.com/amzn/click/com/0201633612" rel="noreferrer" rel="nofollow noreferrer">Design Patterns book</a> uses it regularly throughout its examples.</p>
<p>So in summary, why is <code>friend</code> missing from C#, and what is the "best practice" way (or ways) of simulating it in C#?</p>
<p>(By the way, the <code>internal</code> keyword is <em>not</em> the same thing, it allows <em>all</em> classes within the entire assembly to access <code>internal</code> members, while <code>friend</code> allows you to give a certain class <em>complete access</em> to <em>exactly one</em> other class)</p>

203,629 | <p>Has anyone used OSGi and JSF together?</p>
<p>I ask because JSF uses class-loader magic to find custom components. From a tutorial (emphasis mine):</p>
<blockquote>
<p>This configuration file will end up
being META-INF/faces-config.xml in the
.jar file that represents this
component. <strong>JSF will look for such a
file name in each of the .jar files
that are loaded at runtime</strong> (in the
WEB-INF/lib directory for .war files)
and use each of them in its
configuration. In this way, multiple
component .jar files can be combined
into one web application, and all of
the components described in each .jar
will be available to the application.</p>
</blockquote>
<p>I would like to be able to have JSF custom components as OSGi bundles (i.e. custom components are in different OSGi bundles than the JSF runtime) and for JSF to be able to find these at runtime.</p>
<p>Has anyone done anything similar?</p>

203,754 | <p>I have a thread running in the background that is reading events from an input device in a blocking fashion, now when I exit the application I want to clean up the thread properly, but I can't just run a pthread_join() because the thread would never exit due to the blocking IO.</p>
<p>How do I properly solve that situation? Should I send a pthread_kill(theard, SIGIO) or a pthread_kill(theard, SIGALRM) to break the block? Is either of that even the right signal? Or is there another way to solve this situation and let that child thread exit the blocking read?</p>
<p>Currently a bit puzzled since none of my googling turned up a solution.</p>
<p>This is on Linux and using pthreads.</p>
<p>Edit: I played around a bit with SIGIO and SIGALRM, when I don't install a signal handler they break the blocking IO up, but give a message on the console ("I/O possible") but when I install a signal handler, to avoid that message, they no longer break the blocking IO, so the thread doesn't terminate. So I am kind of back to step one.</p>

203,771 | <p>I have been using CPPUnit as a unit testing framework and am now trying to use it in an automated build and package system. However a problem holding me back is that if a crash occurs during the running of the unit tests, e.g. a null pointer dereferencing, it halts the remainder of the automation.</p>
<p>Is there any way for CPPUnit to recover from the exception, record the test failure and then exist gracefully rather than terminating the unit test process? Even an approach specific to null pointer dereferencing would be useful as that makes up about 90% of the issues I have had.</p>
<p>To be technology-specific, I am using makefiles on a Windows system.</p>

203,809 | <p>This might be a little hard to explain, but I will try.</p>
<p>I want to display a list of categories (stored in 1 table), and number of domains associated with each category (stored in another table). </p>
<p>The monkey wrench in this case is that each domain has a set of records associated with it (which are stored in a 3rd table). I only want to show the categories that have domains associated with them, and the count of domains should reflect only the domains that have records associated with them (from the 3rd table).</p>
<p>My current query</p>
<pre><code>SELECT r.rev_id, c.cat_id, c.cat_name, count(d.dom_id) As rev_id_count FROM reviews r
INNER JOIN domains d ON r.rev_domain_from=d.dom_id
INNER JOIN categories c ON d.dom_catid=c.cat_id
WHERE rev_status = 1
GROUP BY cat_name
ORDER BY cat_name
</code></pre>
<p>This selects the correct category names, but shows a false count (rev_id_count). If the category has 2 domains in it, and each domain has 2 records, it will show count of 4, when it should be 2.</p>

203,844 | <p>I have a form with multiple fields that I'm validating (some with methods added for custom validation) with Jörn Zaeffere's excellent jQuery Validation plugin. How do you circumvent validation with specified submit controls (in other words, fire validation with some submit inputs, but do not fire validation with others)? This would be similar to ValidationGroups with standard ASP.NET validator controls.</p>
<p>My situation:</p>
<p>It's with ASP.NET WebForms, but you can ignore that if you wish. However, I am using the validation more as a "recommendation": in other words, when the form is submitted, validation fires but instead of a "required" message displaying, a "recommendation" shows that says something along the line of "you missed the following fields.... do you wish to proceed anyways?" At that point in the error container there's another submit button now visible that can be pressed which would ignore the validation and submit anyways. How to circumvent the forms .validate() for this button control and still post?</p>
<p>The Buy and Sell a House sample at <a href="http://jquery.bassistance.de/validate/demo/multipart/" rel="noreferrer">http://jquery.bassistance.de/validate/demo/multipart/</a> allows for this in order to hit the previous links, but it does so through creating custom methods and adding it to the validator. I would prefer to not have to create custom methods duplicating functionality already in the validation plugin.</p>
<p>The following is a shortened version of the immediately applicable script that I've got right now:</p>
<pre><code>var container = $("#<%= Form.ClientID %> div.validationSuggestion");
$('#<%= Form.ClientID %>').validate({
errorContainer: container,
errorLabelContainer: $("ul",container),
rules: {
<%= YesNo.UniqueID %>: { required: true },
<%= ShortText.UniqueID %>: { required: true } // etc.
},
messages: {
<%= YesNo.UniqueID %>: 'A message.',
<%= ShortText.UniqueID %>: 'Another message.' // etc.
},
highlight: function(element, errorClass) {
$(element).addClass(errorClass);
$(element.form).find("label[for=" + element.id + "]").addClass(errorClass);
$(element.form).find("label[for=" + element.id + "]").removeClass("valid");
},
unhighlight: function(element, errorClass) {
$(element).removeClass(errorClass);
$(element.form).find("label[for=" + element.id + "]").removeClass(errorClass);
$(element.form).find("label[for=" + element.id + "]").addClass("valid");
},

});

203,854 | <p>Example. 123456, and we want the third from the right ('4') out.</p>
<p>The idea in practise is to access each digit seperately (ie. 6 5 4 3 2 1).</p>
<p>C/C++/C# preferred.</p>

203,859 | <p>Markdown is a great tool for formatting plain text into pretty html, but it doesn't turn plain-text links into URLs automatically. Like this one:</p>
<p><a href="http://www.google.com/" rel="noreferrer">http://www.google.com/</a></p>
<p>How do I get markdown to add tags to URLs when I format a block of text?</p>

203,911 | <p>I am using Java API and XPath to parse my XML. I have XML like this:</p>
<pre><code><animals>
<dog>
<looks>dangerous </looks>
<bites> hard </bites>
<growls> yes </growls>
</dog>
<cat>nothing special</cat>
</animals>
</code></pre>
<p>I would like an XPath condition to print </p>
<pre><code><dog>
<looks>dangerous </looks>
<bites> hard </bites>
<growls> yes </growls>
</dog>
</code></pre>
<p>But I am not able to now. If I use <code>/animal/dog/text()</code> it gives <code>dangerous</code>. But I guess it is used print text alone. Is there a way using XPath condition to fetch a block of XML?</p>
<p><strong>EDIT</strong>:</p>
<p>Thanks a lot for your responses. Appreciate your time spent on this. Is there way to do it in Java without printing the inner text? </p>
<p>Here is where my XPath condition goes:</p>
<pre><code>public static final String XPATH_INPUT_DATA="//text()";

203,918 | <p>Been creating a simple program using VBA that I can use to review vocabulary in Chinese.</p>
<p>I've gotten a fair bit working so far, but have run into a huge problem with inputting a macron-character such as "ā" (unicode 257). The specific application I am working on right now involves changing the contents of the text-box form so that an "a" can automatically be replaced as I type into the text box. Such a procedure itself is easy--I can get it to work with the pinyin characters "á" and "à".</p>
<pre><code>Select Case testchar
Case "a"
Mid(strclip, markloc, 1) = "ā"
End Select
</code></pre>
<p>The previous is an attempt at using the Mid function to replace one character in the textbox string with a pinyin character at the appropriate cue from the user.</p>
<p>The hangup is I can't enter the "ā" into VBA! I've been looking around the internet but this doesn't seem like a problem to anyone else. When I am in the VBA editor and I type alt + 0257, nothing happens. I can't copy-paste from notepad either.. I'm about ready to scrap VBA and redo this application in some other language..</p>
<p>Cheers</p>

203,990 | <p>I'm writing a C++ client which is using libcurl for communicating with a PHP script.</p>
<p>The communication should be session based, and thus the first task is to login and make the PHP script set up a session.</p>
<p>I'm not used to working with sessions either from C++ or PHP. I basically know that it has to do with cookies and communicating session id.</p>
<p>I can't find any example on the curl homepage which demonstrates a simple session management use case.</p>
<p>I'm assuming it has something to do with one or many of the following options in curl:</p>
<pre><code>CURLOPT_COOKIE
CURLOPT_COOKIEFILE
CURLOPT_COOKIEJAR
CURLOPT_COOKIESESSION
CURLOPT_COOKIELIST
</code></pre>
<p>But I can't really see the big picture just from the documentation of CURLOPT_COOKIESESSION for instance.</p>
<p>Anybody who has done this, please share a simple piece of code which shows the concept.</p>
<p>Regards</p>

204,017 | <p>I have a Python script that needs to execute an external program, but for some reason fails.</p>
<p>If I have the following script:</p>
<pre><code>import os;
os.system("C:\\Temp\\a b c\\Notepad.exe");
raw_input();
</code></pre>
<p>Then it fails with the following error:</p>
<blockquote>
<p>'C:\Temp\a' is not recognized as an internal or external command, operable program or batch file.</p>
</blockquote>
<p>If I escape the program with quotes:</p>
<pre><code>import os;
os.system('"C:\\Temp\\a b c\\Notepad.exe"');
raw_input();
</code></pre>
<p>Then it works. However, if I add a parameter, it stops working again:</p>
<pre><code>import os;
os.system('"C:\\Temp\\a b c\\Notepad.exe" "C:\\test.txt"');
raw_input();
</code></pre>
<p>What is the right way to execute a program and wait for it to complete? I do not need to read output from it, as it is a visual program that does a job and then just exits, but I need to wait for it to complete.</p>
<p>Also note, moving the program to a non-spaced path is not an option either.</p>
<hr>
<p>This does not work either:</p>
<pre><code>import os;
os.system("'C:\\Temp\\a b c\\Notepad.exe'");
raw_input();
</code></pre>
<p>Note the swapped single/double quotes.</p>
<p>With or without a parameter to Notepad here, it fails with the error message</p>
<blockquote>
<p>The filename, directory name, or volume label syntax is incorrect.</p>

204,032 | <p>I've run into a problem trying to return an object that holds a collection of childobjects that again can hold a collection of grandchild objects. I get an error, 'connection forcibly closed by host'.</p>
<p>Is there any way to make this work? I currently have a structure resembling this:</p>
<p>pseudo code:</p>
<pre><code>Person:
IEnumerable<Order>
Order:
IEnumerable<OrderLine>
</code></pre>
<p>All three objects have the DataContract attribute and all public properties i want exposed (including the IEnumerable's) have the DataMember attribute.</p>
<p>I have multiple OperationContract's on my service and all the methods returning a single object OR an IEnumerable of an object works perfectly. It's only when i try to nest IEnumerable that it turns bad. Also in my client service reference i picked the generic list as my collection type. I just want to emphasize, <strong>only one of my operations/methods fail with this error - the rest of them work perfectly</strong>.</p>
<p>EDIT (more detailed error description):</p>
<pre><code>[SocketException (0x2746): An existing connection was forcibly closed by
the remote host]
[IOException: Unable to read data from the transport connection:

204,040 | <p>REBOL has no built-in way to perform list comprehensions. However, REBOL has a powerful facility (known as <code>parse</code>) that can be used to create domain-specific languages (DSLs). I've used <code>parse</code> to create such a mini-DSL for list comprehensions. In order to interpret the expression, the block containing the comprehension is passed to a function, which for lack of a better term I've called <code>comprehend</code>.</p>
<p><strong>Example:</strong></p>
<pre><code>comprehend [(a * b) for a in 1x100 for b in 4x10 where (all [odd? a odd? b])]
</code></pre>
<p>For some reason, <code>comprehend</code> doesn't sound right to me, but something like <code>eval</code> is too general.</p>
<p>I haven't found any other language that requires a keyword or function for list comprehensions. They are pure syntactic sugar wherever they exist. Unfortunately I don't have that option. So, seeing that I must have a function, what's a good, succinct, logical name for it?</p>

204,075 | <p>I know many people who use computers every day, who do not know how to select multiple items in a HTML select box/list. I don't want to use this control in my pages any more:</p>
<pre><code>Please pick 3 options:
<select name="categories" size="10" multiple="yes">
</code></pre>
<p>So what user-friendly alternatives do you suggest? Perhaps have 10 tickboxes...or maybe just have each option in a coloured block which changes colour when they click to choose it? This gets messier when I consider my current list of 20 options might grow to 50 eventually.</p>
<p>Whatever way I pick it's gonna be a pain to validate it (using Javascript), to make sure the person picks at least 1 item and not more than 3. It's not about detecting how many options they have picked, the problem is more about how to convey this to the user in a friendly way!</p>
<p><b>Edit:</b>
I suppose I could use tags, like right here on stackoverflow, but I feel these are less appropriate if the users are non-technical (and half of them will be).</p>

Google does not provide much information on the topic.</p>
<p>In short: the Makefile uses the $(wildcard) function at some point, and keeps a directory open, which typically prevents the "make clean" rule to do its work correctly. Re-running "make clean" a second time usually solves it.</p>
<p>I'm using GNU Make version 3.81 under a standard DOS-Box. The author of the post linked to above is using Cygwin.</p>
<p>Has anyone found a fix for this?</p>

204,123 | <p>I am cloning a hidden table row then populating it and after validation I want to show the row using a jquery effect ... say .show("slow")</p>
<pre><code>var baseRow = $("#tasks tr#baseTaskLine");
var newRow = baseRow.clone();
var lastRow = $("#tasks tr[id^='TaskLine_']" + dayClass + ":last");
var newRowId;
if (lastRow.length == 0) {
newRowId = "TaskLine_new0";
}
else {
newRowId = "TaskLine_new" + lastRow[0].rowIndex;
}
newRow.attr("id", newRowId);
:
[populate new row]
:
if (lastRow.length == 0) {
baseRow.after(newRow);
}
else {
lastRow.after(newRow);
}
newRow.hide();
:
:
[validate via webservice call]
:
newRow.show("slow");
</code></pre>
<p>This does show the row but it appears instantly. I have tried hiding all the <code><td></code> elements of the row then showing those and that does seem to work but some strange styles get added to each <code><td></code> which interfere with the formatting i.e. <code>style="display: block;"</code></p>

204,170 | <p>So I need to update a text field. Neither the UPDATE statement or the WRITETEXT statement work when used below</p>
<pre><code>CREATE TABLE MyTable (IDField int, MyField text)
INSERT INTO MyTable (IDField) SELECT 1
DECLARE @Data1 varchar(8000), @Data2 varchar(8000), @ptrval binary(16)
SELECT @Data1 = REPLICATE('1',8000)
SELECT @Data2 = REPLICATE('2',8000)
-- this sets MyField to string of only 8000 characters
UPDATE MyTable SET MyField = @Data1 + @Data2 WHERE IDField = 1
SELECT @ptrval = TEXTPTR(MyField )
FROM MyTable
WHERE IDField = 1
-- this causes an error: Incorrect syntax near '+'.
--WRITETEXT MyTable.MyField @ptrval @Data1 + @Data2
</code></pre>
<p>How am I supposed to do this when local variables cannot be of type TEXT? (If I had SSQL Server 2005 I would use varchar(max) - but I don't)</p>

204,181 | <p>I've got two applications I'm developing using Qt on windows. I want the user to be able to press a button in one application which makes the other application come to the foreground. (The programs communicate using QLocalSocket and named pipes.)</p>
<p>Currently I'm using Qt's QWidget::activateWindow() which occasionally brings the application to the foreground, but most of the time it just highlights the program on the taskbar.</p>
<p>Can someone please tell me how to do this, preferably using Qt although failing that using the WIN32 API would be fine.</p>
<hr>
<p>Unfortunately, I couldn't find a way to do this only with Qt. I solved it using Chris Becke's suggestion of calling SetForegroundWindow from the currently active application.</p>

204,186 | <p>In writing some test code I have found that Selector.select() can return without Selector.selectedKeys() containing any keys to process. This is happening in a tight loop when I register an accept()ed channel with</p>
<pre>SelectionKey.OP_READ | SelectionKey.OP_CONNECT</pre>
<p>as the operations of interest.</p>
<p>According to the docs, select() should return when:</p>
<p>1) There are channels that can be acted upon.</p>
<p>2) You explicitly call Selector.wakeup() - no keys are selected.</p>
<p>3) You explicitly Thread.interrupt() the thread doing the select() - no keys are selected.</p>
<p>If I get no keys after the select() I must be in cases (2) and (3). However, my code is not calling wakeup() or interrupt() to initiate these returns.</p>
<p>Any ideas as to what is causing this behaviour?</p>

204,289 | <p>Been trying to find a working implementation of a WPF listview (or listbox) where
you can order items by dragging them up or down.</p>
<p>I have found a few, but none really works,
for example this one
<a href="http://www.codeproject.com/KB/WPF/ListViewDragDropManager.aspx?msg=2765618#xx2765618xx" rel="nofollow noreferrer">http://www.codeproject.com/KB/WPF/ListViewDragDropManager.aspx?msg=2765618#xx2765618xx</a>
stops working once you have list where you need to scroll down to get to the last items.</p>
<p>Why is Drag&Drop so hard in WPF?
Does anybody know a working control?</p>

204,303 | <p>I'm starting to investigate T4 for Code Generation.</p>
<p>I get that you have a basic template in which you can embed little chunks of c#/vb which can perform clever stuff...</p>
<pre><code><#@ template language="VB" debug="True" hostspecific="True" #>
<#@ output extension=".vb" debug="True" hostspecific="True" #>
Imports System
<#For Each Table as String in New String(0 {"Table1","Table2"}#>
Public Class <#=Table#>DA
Public Sub New
<#= WriteConstructorBody() #>
End Sub
End Class
<#Next#>
<#+
Public Function WriteConstructorBody() as String
return "' Some comment"
End function
#>
</code></pre>
<p>This is great.. However I would like to be able to write my main block thus...</p>
<pre><code><#@ template language="VB" debug="True" hostspecific="True" #>
<#@ output extension=".vb" debug="True" hostspecific="True" #>
Imports System
<#
For Each BaseTableName as String in New String(){"Table1","Table2"}
WriteRecDataInterface(BaseTableName)
WriteRecDataClass(BaseTableName)
WriteDAInterface(BaseTableName)
WriteDAClass(BaseTableName)
Next
#>
</code></pre>
<p>Then I would like to be able to have the WriteX methods exist in a Class Block but themselves be writable using code by example ie escaped Code blocks.</p>
<p>How can I achieve this?</p>

204,308 | <p>I regularly want to check if an object has a member or not. An example is the creation of a singleton in a function. For that purpose, you can use <code>hasattr</code> like this:</p>
<pre><code>class Foo(object):
@classmethod
def singleton(self):
if not hasattr(self, 'instance'):
self.instance = Foo()
return self.instance
</code></pre>
<p>But you can also do this:</p>
<pre><code>class Foo(object):
@classmethod
def singleton(self):
try:
return self.instance
except AttributeError:
self.instance = Foo()
return self.instance
</code></pre>
<p>Is one method better of the other?</p>
<p><strong>Edit:</strong> Added the <code>@classmethod</code> ... But note that the question is <em>not</em> about how to make a singleton but how to check the presence of a member in an object.</p>
<p><strong>Edit:</strong> For that example, a typical usage would be:</p>
<pre><code>s = Foo.singleton()
</code></pre>
<p>Then <code>s</code> is an object of type <code>Foo</code>, the same each time. And, typically, the method is called many times.</p>

<p><a href="http://perldoc.perl.org/UNIVERSAL.html" rel="noreferrer">http://perldoc.perl.org/UNIVERSAL.html</a></p>
<p>I shouldn't use UNIVERSAL::isa() and should instead use $obj->isa() or CLASS->isa().</p>
<p>This means that to find out if something is a reference in the first place and then is reference to this class I have to do</p>
<pre><code>eval { $poss->isa("Class") }

<p>and check $@ and all that gumph, or else</p>
<pre><code>use Scalar::Util 'blessed';
blessed $ref && $ref->isa($class);
</code></pre>
<p>My question is why? What's wrong with UNIVERSAL::isa called like that? It's much cleaner for things like:</p>
<pre><code>my $self = shift if UNIVERSAL::isa($_[0], __PACKAGE__)
</code></pre>
<p>To see whether this function is being called on the object or not. And is there a nice clean alternative that doesn't get cumbersome with ampersands and potentially long lines?</p>

204,334 | <p><strong>What?</strong></p>
<p>I have a DLGTEMPLATE loaded from a resource DLL, how can I change the strings assigned to the controls at runtime programmatically?</p>
<p>I want to be able to do this before the dialog is created, such that I can tell that the strings on display came from the resource DLL, and not from calls to SetWindowText when the dialog is initialized.</p>
<p>Google has found examples of creating DLGTEMPLATE in code, or twiddling simple style bits but nothing on editing the strings in memory.</p>
<p><strong>How?</strong></p>
<p>I am doing this by hooking the Dialog/Property Sheet creation API's. Which gives me access to the DLGTEMPLATE before the actual dialog is created and before it has a HWND. </p>
<p><strong>Why?</strong></p>
<p>I want to be able to do runtime localization, and localization testing. I already have this implemented for loading string (including the MFC 7.0 wrapper), menus and accelerator tables, but I am struggling to handle dialog/property sheet creation.</p>
<p>Code examples would be the perfect answer, ideally a class to wrap around the DLGTEMPLATE, if I work out my own solution I will post it.</p>

204,369 | <p>Recently our company has started measuring the cyclomatic complexity (CC) of the functions in our code on a weekly basis, and reporting which functions have improved or worsened. So we have started paying a lot more attention to the CC of functions.</p>
<p>I've read that CC could be informally calculated as 1 + the number of decision points in a function (e.g. if statement, for loop, select etc), or also the number of paths through a function...</p>
<p>I understand that the easiest way of reducing CC is to use the Extract Method refactoring repeatedly...</p>
<p>There are somethings I am unsure about, e.g. what is the CC of the following code fragments?</p>
<p>1)</p>
<pre><code>for (int i = 0; i < 3; i++)
Console.WriteLine("Hello");
</code></pre>
<p>And</p>
<pre><code>Console.WriteLine("Hello");
Console.WriteLine("Hello");
Console.WriteLine("Hello");
</code></pre>
<p>They both do the same thing, but does the first version have a higher CC because of the for statement?</p>
<p>2)</p>
<pre><code>if (condition1)
if (condition2)
if (condition 3)
Console.WriteLine("wibble");
</code></pre>
<p>And</p>
<pre><code>if (condition1 && condition2 && condition3)
Console.WriteLine("wibble");
</code></pre>
<p>Assuming the language does short-circuit evaluation, such as C#, then these two code fragments have the same effect... but is the CC of the first fragment higher because it has 3 decision points/if statements?</p>
<p>3)</p>
<pre><code>if (condition1)
{
Console.WriteLine("one");
if (condition2)
Console.WriteLine("one and two");
}
</code></pre>
<p>And</p>
<pre><code>if (condition3)
Console.WriteLine("fizz");
if (condition4)
Console.WriteLine("buzz");
</code></pre>
<p>These two code fragments do different things, but do they have the same CC? Or does the nested if statement in the first fragment have a higher CC? i.e. nested if statements are mentally more complex to understand, but is that reflected in the CC?</p>

204,396 | <p>When returning objects from a class, when is the right time to release the memory?</p>
<p>Example,</p>
<pre><code>class AnimalLister
{
public:
Animal* getNewAnimal()
{
Animal* animal1 = new Animal();
return animal1;
}
}
</code></pre>
<p>If i create an instance of Animal Lister and get Animal reference from it, then where am i supposed to delete it?</p>
<pre><code>int main() {
AnimalLister al;
Animal *a1, *a2;
a1 = al.getNewAnimal();
a2 = al.getNewAnimal();
}
</code></pre>
<p>The problem here is AnimalLister doesnot have a way to track the list of Animals Created, so how do i change the logic of such code to have a way to delete the objects created.</p>

204,398 | <p>Let's have the following class hierarchy:</p>
<pre><code>public class ParentClass implements SomeInterface {

public class ChildClass extends ParentClass {

<p>Then let's have these two instances:</p>
<pre><code>ParentClass parent;
ChildClass child;
</code></pre>
<p>Then we have the following TRUE statements</p>
<pre><code>(parent instanceof SomeInterface) == true
(child instanceof SomeInterface) == true

<p>Is it possible to unimplement the SomeInterface in the ChildClass, so when we check with the instanceof operator it returns false?</p>

204,406 | <p>I am trying to convert all DateTime values in a DataTable to strings. Here is the method I use:</p>
<pre><code>private static void ConvertDateTimesToStrings(DataTable dataTable)
{
if (dataTable == null)
{
return;
}
for (int rowIndex = 0; rowIndex < dataTable.Rows.Count; rowIndex++ )
{
for (int i = 0; i < dataTable.Columns.Count; i++)
{
DateTime dateTime;
try
{
dateTime = (DateTime)dataTable.Rows[rowIndex][i];
}
catch (InvalidCastException)
{
continue;
}
dataTable.Rows[rowIndex][i] = dateTime.ToString("dd.MM.yyyy hh:mm:ss");
}
}
}
</code></pre>
<p>After this line works:</p>
<pre><code>dataTable.Rows[rowIndex][i] = dateTime.ToString("dd.MM.yyyy hh:mm:ss");
</code></pre>
<p>I check the value of dataTable.Rows[rowIndex][i] and see it is still a DateTime, not a string. Why does this happen and how can I solve this?</p>
<p>Edit: I am trying to do this because I am fighting an api and unfortunately I do not have the choice of which component to use.</p>

204,444 | <p>As can be seen in the Mozilla changlog for JavaScript 1.7 they have added destructuring assignment. Sadly I'm not very fond of the syntax (why write a and b twice?):</p>
<pre><code>var a, b;
[a, b] = f();
</code></pre>
<p>Something like this would have been a lot better:</p>
<pre><code>var [a, b] = f();
</code></pre>
<p>That would still be backwards compatible. Python-like destructuring would not be backwards compatible.</p>
<p>Anyway the best solution for JavaScript 1.5 that I have been able to come up with is:</p>
<pre><code>function assign(array, map) {
var o = Object();
var i = 0;
$.each(map, function(e, _) {
o[e] = array[i++];
});
return o;
}
</code></pre>
<p>Which works like:</p>
<pre><code>var array = [1,2];
var _ = assign[array, { var1: null, var2: null });
_.var1; // prints 1
_.var2; // prints 2
</code></pre>
<p>But this really sucks because _ has no meaning. It's just an empty shell to store the names. But sadly it's needed because JavaScript doesn't have pointers. On the plus side you can assign default values in the case the values are not matched. Also note that this solution doesn't try to slice the array. So you can't do something like <code>{first: 0, rest: 0}</code>. But that could easily be done, if one wanted that behavior.</p>
<p>What is a better solution?</p>

204,465 | <p>I'm planning to develop an app for the iPhone and that app would have to access a couple of SOAP services. While doing some basic checking in the iPhone SDK I was not able to find any support for accessing SOAP services, a bit of Googling lead to the conclusion that there is no support for SOAP in the iPhone SDK. </p>
<p>So if I do want to build that app I'll need to come up with a approach to access SOAP services from the iPhone. What would be the best approach? Any best practices? Did someone already write a library using the functionality that is present in the iPhone SDK to access SOAP services?</p>
<p>(Since the service I need to access is exposed by another party and they only expose it as SOAP, it's unfortunately not an option to switch to another type of interface (e.g. REST based API).</p>

204,467 | <p>I have trouble using Perl grep() with a string that <em>may</em> contain chars that are interpreted as regular expressions quantifiers. </p>
<p>I got the following error when the grep pattern is "g++" because the '+' symbols
are interpreted as quantifiers. Here is the output of for program that follows:</p>
<pre><code>1..3
ok 1 - grep, pattern not found
ok 2 - grep, pattern found
Nested quantifiers in regex; marked by <-- HERE
in m/g++ <-- HERE / at escape_regexp_quantifier.pl line 8.
</code></pre>
<p>Is there a modifier I could use to indicate to grep that the quantifiers shall be ignored,
or is there a function that would escape the quantifiers ?</p>
<pre><code>#! /usr/bin/perl
sub test_grep($)
{
my $filter = shift;
my @output = ("-r-xr-xr-x 3 root bin 122260 Jan 23 2005 gcc",
"-r-xr-xr-x 4 root bin 124844 Jan 23 2005 g++");
return grep (!/$filter/, @output);
}
use Test::Simple tests => 2;
ok(test_grep("foo"), "grep, pattern not found");
ok(test_grep("gcc"), "grep, pattern found");
ok(test_grep("g++"), "grep, pattern found");
</code></pre>
<p>PS: in addition to the answer question above, I welcome any feedback on Perl usage in the above as I'm still learning. Thanks</p>

204,488 | <p>I am trying to create a new contact using Dynamic Entity. The sample i found in CRM SDK had this code.</p>
<pre><code>// Set the properties of the contact using property objects.
StringProperty firstname = new StringProperty();
firstname.Name = "firstname";
firstname.Value = "Jesper";
StringProperty lastname = new StringProperty();
lastname.Name = "lastname";
lastname.Value = "Aaberg";
// Create the DynamicEntity object.
DynamicEntity contactEntity = new DynamicEntity();
// Set the name of the entity type.
contactEntity.Name = EntityName.contact.ToString();
// Set the properties of the contact.
contactEntity.Properties = new Property[] {firstname, lastname};
</code></pre>
<p>In my code i have the following implementation.</p>
<pre><code> StringProperty sp_Field1 = new StringProperty("Field1","Value1");
StringProperty sp_Field2 = new StringProperty("Field2","Value1");
CrmService service = new CrmService();
service.Credentials = System.Net.CredentialCache.DefaultCredentials;
// Create the DynamicEntity object.
DynamicEntity contactEntity = new DynamicEntity();
// Set the name of the entity type.
contactEntity.Name = EntityName.contact.ToString();
// Set the properties of the contact.
contactEntity.Properties = new Property[] {sp_Field1,sp_Field2};
</code></pre>
<p>I don't see much differences in the code. In the examples i found in the internet i have the same implementation as i found in SDK. But if i run the same i get the following error</p>
<blockquote>
<p>CS0029: Cannot implicitly convert type 'Microsoft.Crm.Sdk.StringProperty' to 'Microsoft.Crm.Sdk.PropertyCollection'</p>
</blockquote>
<p>I tried created a new variable of type PropertyCollection(one that belongs in mscrm namespace) and added the stringpropertys into that and passed it to the entity. </p>
<pre><code>Microsoft.Crm.Sdk.PropertyCollection propTest = new Microsoft.Crm.Sdk.PropertyCollection();
propTest.Add(sp_SSNNo);
propTest.Add(sp_FirstName);
contactEntity.Properties = new Property[] {propTest};
</code></pre>
<p>This gave me the following error</p>
<blockquote>
<p>CS0029: Cannot implicitly convert type 'Microsoft.Crm.Sdk.PropertyCollection' to 'Microsoft.Crm.Sdk.Property'</p>
</blockquote>
<p>I am sure its a minor typecasting error but i am not able to figure out where the error is. And moreover, even if it was a typecasting error why is it working for all the samples given in the internet and not for me. I tried getting the code sample to run but i am encountering the same conversion error. Please let me know if you need more info on this, any help on this would be appreciated.</p>

204,548 | <p>How to change overview rule <strong>background</strong> color in Eclipse 3.4.0.I20080617-2000 (vertical bar on right of editing window with some annotations) ? </p>
<p>General > Editors > Text Editors > Annotations allows only to change colors of marks itself not background of whole bar.</p>
<p>It looks like my web searching skills are getting weaker since I cannot find it anywhere ... </p>

204,549 | <p>I need to insert some data into a table in Oracle. </p>
<p>The only problem is one of the fields is a timestamp(6) type and it is required data. I don't care about what actually goes in here I just need to get the right syntax for an entry so that the database will accept it.</p>
<p>I'm using the gui web client to enter data however I don't mind using raw SQL if I have to.</p>
<p>Thanks.</p>

204,557 | <p>I'm working on scripts that apply database schema updates. I've setup all my SQL update scripts using start transaction/commit. I pass these scripts to psql on the command line.</p>
<p>I now need to apply multiple scripts at the same time, and in one transaction. So far the only solution I've come up with is to remove the start transaction/commit from the original set of scripts, then jam them together inside a new start transaction/commit block. I'm writing perl scripts to do this on the fly.</p>
<p>Effectively I want nested transactions, which I can't figure out how to do in postgresql. </p>
<p>Is there any way to do or simulate nested transactions for this purpose? I have things setup to automatically bail out on any error, so I don't need to continue in the top level transaction if any of the lower ones fail.</p>

204,564 | <p>Is there any way to get the custom attributes of a specific object I am receiving in a method?</p>
<p>I do not want nor can to iterate over Type.GetMembers() and search for my member. I have the object, which is also a member, that has the attribute.</p>
<p>How do I get the attribute?</p>
<pre><code>class Custom
{
[Availability]
private object MyObject = "Hello";
private void Do(object o)
{
//does object 'o' has any custom attributes of type 'Availability'?
}
//somewhere I make the call: Do(MyObject)
}
</code></pre>
