58,280 | <p>Is it possible to use an UnhandledException Handler in a Windows Service?</p>
<p>Normally I would use a custom built Exception Handling Component that does logging, phone home, etc. This component adds a handler to System.AppDomain.CurrentDomain.UnhandledException but as far as I can tell this doesn’t achieve anything win a Windows Service so I end up with this pattern in my 2 (or 4) Service entry points:</p>
<pre>
<code>
Protected Overrides Sub OnStart(ByVal args() As String)
' Add code here to start your service. This method should set things
' in motion so your service can do its work.
Try
MyServiceComponent.Start()
Catch ex As Exception
'call into our exception handler
MyExceptionHandlingComponent.ManuallyHandleException (ex)
'zero is the default ExitCode for a successfull exit, so if we set it to non-zero
ExitCode = -1
'So, we use Environment.Exit, it seems to be the most appropriate thing to use
'we pass an exit code here as well, just in case.
System.Environment.Exit(-1)
End Try
End Sub
</code>
</pre>
<p>Is there a way my Custom Exception Handling component can deal with this better so I don't have to fill my OnStart with messy exception handling plumbing?</p>

58,306 | <p>I am trying to determine the best time efficient algorithm to accomplish the task described below.</p>
<p>I have a set of records. For this set of records I have connection data which indicates how pairs of records from this set connect to one another. This basically represents an undirected graph, with the records being the vertices and the connection data the edges.</p>
<p>All of the records in the set have connection information (i.e. no orphan records are present; each record in the set connects to one or more other records in the set).</p>
<p>I want to choose any two records from the set and be able to show all simple paths between the chosen records. By "simple paths" I mean the paths which do not have repeated records in the path (i.e. finite paths only).</p>
<p>Note: The two chosen records will always be different (i.e. start and end vertex will never be the same; no cycles).</p>
<p>For example:</p>
<pre>
If I have the following records:
A, B, C, D, E
and the following represents the connections:
(A,B),(A,C),(B,A),(B,D),(B,E),(B,F),(C,A),(C,E),
(C,F),(D,B),(E,C),(E,F),(F,B),(F,C),(F,E)
[where (A,B) means record A connects to record B]
</pre>
<p>If I chose B as my starting record and E as my ending record, I would want to find all simple paths through the record connections that would connect record B to record E.</p>
<pre>
All paths connecting B to E:
B->E
B->F->E
B->F->C->E
B->A->C->E
B->A->C->F->E
</pre>
<p>This is an example, in practice I may have sets containing hundreds of thousands of records.</p>

58,354 | <p>What are some simple algorithm or data structure related "white boarding" problems that you find effective during the candidate screening process?</p>
<p>I have some simple ones that I use to validate problem solving skills and that can be simply expressed but have some opportunity for the application of some heuristics.</p>
<p>One of the basics that I use for junior developers is:</p>
<blockquote>
<p>Write a C# method that takes a string which contains a set of words (a sentence) and rotates those words X number of places to the right. When a word in the last position of the sentence is rotated it should show up at the front of the resulting string.</p>
</blockquote>
<p>When a candidate answers this question I look to see that they available .NET data structures and methods (string.Join, string.Split, List, etc...) to solve the problem. I also look for them to identify special cases for optimization. Like the number of times that the words need to be rotated isn't really X it's X % number of words.</p>
<p>What are some of the white board problems that you use to interview a candidate and what are some of the things you look for in an answer (do not need to post the actual answer).</p>

58,429 | <p>How can I have SQL repeat some set-based operation an arbitrary number of times without looping? How can I have SQL perform an operation against a range of numbers? I'm basically looking for a way to do a set-based for loop.<p>
I know I can just create a small table with integers in it, say from 1 to 1000 and then use it for range operations that are within that range.
<p>For example, if I had that table I could make a select to find the sum of numbers 100-200 like this:</p>
<pre><code>select sum(n) from numbers where n between 100 and 200
</code></pre>
<p>Any ideas? I'm kinda looking for something that works for T-SQL but any platform would be okay.</p>
<p>[Edit] I have my own solution for this using SQL CLR which works great for MS SQL 2005 or 2008. <a href="https://stackoverflow.com/questions/58429/sql-set-based-range#59657">See below.</a></p>

58,431 | <p>I have wondered for some time, what a nice, clean solution for joining an array of strings might look like.
Example: I have ["Alpha", "Beta", "Gamma"] and want to join the strings into one, separated by commas – "Alpha, Beta, Gamma".</p>
<p>Now I know that most programming languages offer some kind of join method for this. I just wonder how these might be implemented.
When I took introductory courses, I often tried to go it alone, but never found a satisfactory algorithm. Everything seemed rather messy, the problem being that you can not just loop through the array, concatenating the strings, as you would add one too many commas (either before or after the last string).
I don’t want to check conditions in the loop. I don’t really want to add the first or the last string before/after the loop (I guess this is maybe the best way?).</p>
<p>Can someone show me an elegant solution? Or tell me exactly why there can’t be anything more elegant?</p>

58,482 | <p>I'm not entirely sure if this is possible in Ruby, but hopefully there's an easy way to do this. I want to declare a variable and later find out the name of the variable. That is, for this simple snippet:</p>
<pre><code>foo = ["goo", "baz"]
</code></pre>
<p>How can I get the name of the array (here, "foo") back? If it is indeed possible, does this work on any variable (e.g., scalars, hashes, etc.)?</p>
<p>Edit: Here's what I'm basically trying to do. I'm writing a SOAP server that wraps around a class with three important variables, and the validation code is essentially this:</p>
<pre><code> [foo, goo, bar].each { |param|
if param.class != Array
puts "param_name wasn't an Array. It was a/an #{param.class}"
return "Error: param_name wasn't an Array"
end
}
</code></pre>
<p>My question is then: Can I replace the instances of 'param_name' with foo, goo, or bar? These objects are all Arrays, so the answers I've received so far don't seem to work (with the exception of re-engineering the whole thing ala <a href="https://stackoverflow.com/questions/58482/ruby-get-a-variables-name#58870">dbr's answer</a>) </p>

58,493 | <p>I have an array of numbers that potentially have up to 8 decimal places and I need to find the smallest common number I can multiply them by so that they are all whole numbers. I need this so all the original numbers can all be multiplied out to the same scale and be processed by a sealed system that will only deal with whole numbers, then I can retrieve the results and divide them by the common multiplier to get my relative results.</p>
<p>Currently we do a few checks on the numbers and multiply by 100 or 1,000,000, but the processing done by the *sealed system can get quite expensive when dealing with large numbers so multiplying everything by a million just for the sake of it isn’t really a great option. As an approximation lets say that the sealed algorithm gets 10 times more expensive every time you multiply by a factor of 10.</p>
<p>What is the most efficient algorithm, that will also give the best possible result, to accomplish what I need and is there a mathematical name and/or formula for what I’m need?</p>
<p>*The sealed system isn’t really sealed. I own/maintain the source code for it but its 100,000 odd lines of proprietary magic and it has been thoroughly bug and performance tested, altering it to deal with floats is not an option for many reasons. It is a system that creates a grid of X by Y cells, then rects that are X by Y are dropped into the grid, “proprietary magic” occurs and results are spat out – obviously this is an extremely simplified version of reality, but it’s a good enough approximation.</p>
<p>So far there are quiet a few good answers and I wondered how I should go about choosing the ‘correct’ one. To begin with I figured the only fair way was to create each solution and performance test it, but I later realised that pure speed wasn’t the only relevant factor – an more accurate solution is also very relevant. I wrote the performance tests anyway, but currently the I’m choosing the correct answer based on speed as well accuracy using a ‘gut feel’ formula.</p>
<p>My performance tests process 1000 different sets of 100 randomly generated numbers.
Each algorithm is tested using the same set of random numbers.
Algorithms are written in .Net 3.5 (although thus far would be 2.0 compatible)
I tried pretty hard to make the tests as fair as possible.</p>
<ul>
<li>Greg – Multiply by large number
and then divide by GCD – 63
milliseconds</li>
<li>Andy – String Parsing
– 199 milliseconds </li>
<li>Eric – Decimal.GetBits – 160 milliseconds</li>
<li>Eric – Binary search – 32
milliseconds </li>
<li>Ima – sorry I couldn’t
figure out a how to implement your
solution easily in .Net (I didn’t
want to spend too long on it) </li>
<li>Bill – I figure your answer was pretty
close to Greg’s so didn’t implement
it. I’m sure it’d be a smidge faster
but potentially less accurate.</li>
</ul>
<p>So Greg’s Multiply by large number and then divide by GCD” solution was the second fastest algorithm and it gave the most accurate results so for now I’m calling it correct.</p>
<p>I really wanted the Decimal.GetBits solution to be the fastest, but it was very slow, I’m unsure if this is due to the conversion of a Double to a Decimal or the Bit masking and shifting. There should be a
similar usable solution for a straight Double using the BitConverter.GetBytes and some knowledge contained here: <a href="http://blogs.msdn.com/bclteam/archive/2007/05/29/bcl-refresher-floating-point-types-the-good-the-bad-and-the-ugly-inbar-gazit-matthew-greig.aspx" rel="nofollow noreferrer">http://blogs.msdn.com/bclteam/archive/2007/05/29/bcl-refresher-floating-point-types-the-good-the-bad-and-the-ugly-inbar-gazit-matthew-greig.aspx</a> but my eyes just kept glazing over every time I read that article and I eventually ran out of time to try to implement a solution.</p>
<p>I’m always open to other solutions if anyone can think of something better.</p>

58,520 | <p>We need to regularly synchronize many dozens of binary files (project executables and DLLs) between many developers at several different locations, so that every developer has an up to date environment to build and test at. Due to nature of the project, updates must be done often and on-demand (overnight updates are not sufficient). This is not pretty, but we are stuck with it for a time.</p>
<p>We settled on using a regular version (source) control system: put everything into it as binary files, get-latest before testing and check-in updated DLL after testing.</p>
<p>It works fine, but a version control client has a lot of features which don't make sense for us and people occasionally get confused.</p>
<p>Are there any tools better suited for the task? Or may be a completely different approach?</p>
<p><strong>Update:</strong> </p>
<p>I need to clarify that it's not a tightly integrated project - more like extensible system with a heap of "plugins", including thrid-party ones. We need to make sure those modules-plugins works nicely with recent versions of each other and the core. Centralised build as was suggested was considered initially, but it's not an option.</p>

58,540 | <p>When trying to enter a SQL query with parameters using the Oracle OLE DB provider I get the following error:</p>

58,543 | <p>I have an application that I would like to embed inside our companies CMS. The only way to do that (I am told), is to load it in an <code><iframe></code>.</p>
<p>Easy: just set <code>height</code> and <code>width</code> to <code>100%</code>! Except, it doesn't work.</p>
<p>I did find out about setting <code>frameborder</code> to <code>0</code>, so it at least <em>looks</em> like part of the site, but I'd prefer not to have an ugly scrollbar <em>inside</em> a page that allready has one.</p>
<p>Do you know of any tricks to do this?</p>
<p><strong>EDIT:</strong> I think I need to clarify my question somewhat:</p>
<ul>
<li>the company CMS displays the fluff and stuff for our whole website</li>
<li>most pages created through the CMS</li>
<li>my application isn't, but they will let me embedd it in an <code><iframe></code></li>
<li>I have no control over the <code>iframe</code>, so any solution must work from the referenced page (according to the <code>src</code> attribute of the <code>iframe</code> tag)</li>
<li>the CMS displays a footer, so setting the height to 1 million pixels is not a good idea</li>
</ul>
<p>Can I access the parent pages DOM from the referenced page? This might help, but I can see some people might not want this to be possible...</p>
<p>This technique seems to work (<a href="http://bytes.com/forum/thread91876.html" rel="noreferrer">gleaned</a> from several sources, but inspired by the <a href="http://brondsema.net/blog/index.php/2007/06/06/100_height_iframe" rel="noreferrer">link</a> from the accepted answer:</p>
<p>In parent document:</p>
<pre><code><iframe id="MyIFRAME" name="MyIFRAME"
src="http://localhost/child.html"
scrolling="auto" width="100%" frameborder="0">
no iframes supported...
</iframe>
</code></pre>
<p>In child:</p>
<pre><code><!-- ... -->
<body>
<script type="text/javascript">
function resizeIframe() {
var docHeight;
if (typeof document.height != 'undefined') {
docHeight = document.height;
}
else if (document.compatMode && document.compatMode != 'BackCompat') {
docHeight = document.documentElement.scrollHeight;
}
else if (document.body
&& typeof document.body.scrollHeight != 'undefined') {
docHeight = document.body.scrollHeight;
}
// magic number: suppress generation of scrollbars...
docHeight += 20;
parent.document.getElementById('MyIFRAME').style.height = docHeight + "px";
}
parent.document.getElementById('MyIFRAME').onload = resizeIframe;
parent.window.onresize = resizeIframe;
</script>
</body>
</code></pre>
<p><strong>BTW:</strong> This will only work if parent and child are in the same domain due to a restriction in JavaScript for security reasons...</p>

58,547 | <p>In C++ we acquiring a resource in a constructor and release it in a destructor.</p>
<p>So when an exception rises in a middle of a function there will be no resource leak or locked mutexes or whatever.</p>
<p>AFAIK java classes don't have destructors. So how does one do the resource management in Java.</p>
<p>For example:</p>
<pre><code>public int foo() {
Resource f = new Resource();
DoSomething(f);
f.Release();
}
</code></pre>
<p>How can one release resource if DoSomething throws an exception? We can't put try\catch blocks all over the code, can we?</p>

58,554 | <p>I'm using Eclipse as my IDE for a C++ project, and I would love for it to tell me where a given symbol is defined and what the parameters are for a function.</p>
<p>However, there's a catch: I also use <a href="http://www.lazycplusplus.com/" rel="nofollow noreferrer">Lazy C++</a>, a tool that takes a single source file and generates the .h and the .cpp files. Those .lzz files look like headers, but this tool supports some very mild syntactic benefits, like combining nested namespaces into a qualified name. Additionally, it has some special tags to tell the tool specifically where to put what (in header or in source file).</p>
<p>So my typical SourceFile.lzz looks like this:</p>
<pre><code>$hdr
#include <iosfwd>
#include "ProjectA/BaseClass.h"
$end
$src
#include <iostream>
#include "ProjectB/OtherClass.h"
$end
// Forward declarations
namespace BigScope::ProjectB
{
class OtherClass;
}
namespace BigScope::ProjectA
{
class MyClass : public ProjectA::BaseClass
{
void SomeMethod(const ProjectB::OtherClass& Foo) { }
}
}
</code></pre>
<p>As you see, it's still recognizable C++, but with a few extras.</p>
<p>For some reason, CDT's indexer does not seem to want to index anything, and I don't know what's wrong. In the Indexer View, it shows me an empty tree, but tells me that it has some 15000 symbols and more stuff, none of which I can seem to access.</p>
<p>So here's my <strong>question</strong>: how can I make the Indexer output some more information about what it's doing and why it fails when it does so, and can I tweak it more than with just the GUI-accessible options?</p>
<p>Thanks,</p>
<p>Carl</p>

58,558 | <p>I'm trying to check, using an automated discovery tool, when JAR files in remote J2EE application servers have changed content. Currently, the system downloads the whole JAR using WMI to checksum it locally, which is slow for large JARs.</p>
<p>For UNIXy servers (and Windows servers with Cygwin), I can just log in over SSH and run <code>md5sum foo.jar</code>. Ideally, I'd like to avoid installing extra software on the remote servers (there may be thousands), so is there a good way to do this on vanilla Windows servers?</p>

58,584 | <p>Selecting a large amount of text that extends over many screens in an IDE like Eclipse is fairly easy since you can use the mouse, but what is the best way to e.g. select and delete multiscreen blocks of text or write e.g. three large methods out to another file and then delete them for testing purposes in Vim when using it via putty/ssh where you cannot use the mouse?</p>
<p>I can easily yank-to-the-end-of-line or yank-to-the-end-of-code-block but if the text extends over many screens, or has lots of blank lines in it, I feel like my hands are tied in Vim. Any solutions?</p>
<p>And a related question: is there a way to somehow select 40 lines, and then comment them all out (with "#" or "//"), as is common in most IDEs?</p>

58,614 | <p>I'm developing a multi-threaded app for a Linux embedded platform.</p>
<p>At the moment I'm setting the stack size for each thread (via pthread_set_attr) to a fairly large default value. I would like to fine tune that value for each thread to something smaller to reduce my application's memory usage. I could go through the trial and error route of setting each thread's stack size to progressively smaller values until the program crashed, but the application uses ~15 threads each with completely different functionality/attributes so that approach would be extremely time consuming.</p>
<p>I would much rather prefer being able to directly measure each thread's stack usage. Is there some utility people can recommend to do this? (For example, I come from a vxWorks background and using the 'ti' command from the vxWorks shell directly gives stats on the stack usage as well as other useful info on the task status.)</p>
<p>Thanks</p>

<p>I've done something similar in the past where I've used a polygon to create a mask by drawing into a bitmap and filling values, then converting the bitmap into an array that I can manipulate. I'm sure there's a better method for doing this!</p>

58,711 | <p>I have been playing with the Ruby library "shoes". Basically you can write a GUI application in the following way:</p>
<pre><code>Shoes.app do
t = para "Not clicked!"
button "The Label" do
alert "You clicked the button!" # when clicked, make an alert
t.replace "Clicked!" # ..and replace the label's text
end
end

<p>This made me think - how would I design a similarly nice-to-use GUI framework in Python? One that doesn't have the usual tyings of basically being wrappers to a C* library (In the case of GTK, Tk, wx, QT etc etc)</p>
<p>Shoes takes things from web devlopment (like <code>#f0c2f0</code> style colour notation, CSS layout techniques, like <code>:margin => 10</code>), and from ruby (extensively using blocks in sensible ways)</p>
<p>Python's lack of "rubyish blocks" makes a (metaphorically)-direct port impossible:</p>
<pre><code>def Shoeless(Shoes.app):
self.t = para("Not clicked!")
def on_click_func(self):
alert("You clicked the button!")
self.t.replace("clicked!")
b = button("The label", click=self.on_click_func)
</code></pre>
<p>No where near as clean, and wouldn't be <em>nearly</em> as flexible, and I'm not even sure if it would be implementable.</p>
<p>Using decorators seems like an interesting way to map blocks of code to a specific action:</p>
<pre><code>class BaseControl:
def __init__(self):
self.func = None
def clicked(self, func):
self.func = func
def __call__(self):
if self.func is not None:
self.func()
class Button(BaseControl):
pass
class Label(BaseControl):
pass
# The actual applications code (that the end-user would write)
class MyApp:
ok = Button()
la = Label()
@ok.clicked
def clickeryHappened():
print "OK Clicked!"
if __name__ == '__main__':
a = MyApp()
a.ok() # trigger the clicked action
</code></pre>
<p>Basically the decorator function stores the function, then when the action occurred (say, a click) the appropriate function would be executed.</p>
<p>The scope of various stuff (say, the <code>la</code> label in the above example) could be rather complicated, but it seems doable in a fairly neat manner..</p>

58,743 | <p>As an example take the following code:</p>
<pre><code>public enum ExampleEnum { FooBar, BarFoo }
public class ExampleClass : INotifyPropertyChanged
{
private ExampleEnum example;
public ExampleEnum ExampleProperty
{ get { return example; } { /* set and notify */; } }
}
</code></pre>
<p>I want a to databind the property ExampleProperty to a ComboBox, so that it shows the options "FooBar" and "BarFoo" and works in mode TwoWay. Optimally I want my ComboBox definition to look something like this:</p>
<pre><code><ComboBox ItemsSource="What goes here?" SelectedItem="{Binding Path=ExampleProperty}" />
</code></pre>
<p>Currently I have handlers for the ComboBox.SelectionChanged and ExampleClass.PropertyChanged events installed in my Window where I do the binding manually.</p>
<p>Is there a better or some kind of canonical way? Would you usually use Converters and how would you populate the ComboBox with the right values? I don't even want to get started with i18n right now.</p>
<p><strong>Edit</strong></p>
<p>So one question was answered: How do I populate the ComboBox with the right values.</p>
<p>Retrieve Enum values as a list of strings via an ObjectDataProvider from the static Enum.GetValues method:</p>
<pre><code><Window.Resources>
<ObjectDataProvider MethodName="GetValues"
ObjectType="{x:Type sys:Enum}"
x:Key="ExampleEnumValues">
<ObjectDataProvider.MethodParameters>
<x:Type TypeName="ExampleEnum" />
</ObjectDataProvider.MethodParameters>
</ObjectDataProvider>
</Window.Resources>
</code></pre>
<p>This I can use as an ItemsSource for my ComboBox:</p>
<pre><code><ComboBox ItemsSource="{Binding Source={StaticResource ExampleEnumValues}}"/>
</code></pre>

<p>There doesn't appear to be a way to do this using <code>System.IO</code> classes without lots of recursion.</p>
<p>There is a method in VB that we can use if we add a reference to <code>Microsoft.VisualBasic</code>:</p>
<pre><code>new Microsoft.VisualBasic.Devices.Computer().
FileSystem.CopyDirectory( sourceFolder, outputFolder );

58,827 | <p>OK, I am not sure if the title it completely accurate, open to suggestions!</p>
<p>I am in the process of creating an ASP.NET custom control, this is something that is still relatively new to me, so please bear with me.</p>
<p>I am thinking about the event model. Since we are not using Web Controls there are no events being fired from buttons, rather I am manually calling <strong>__doPostBack</strong> with the appropriate arguments. However this can obviously mean that there are a lot of postbacks occuring when say, selecting options (which render differently when selected).</p>
<p>In time, I will need to make this more Ajax-y and responsive, so I will need to change the event binding to call local Javascript.</p>
<p>So, I was thinking I should be able to toggle the "mode" of the control, it can either use postback and handlle itself, or you can specify the Javascript function names to call instead of the doPostBack.</p>
<ul>
<li>What are your thoughts on this?</li>
<li>Am I approaching the raising of the events from the control in the wrong way? (totally open to suggestions here!)</li>
<li>How would you approach a similar problem?
<hr></li>
</ul>
<h2>Edit - To Clarify</h2>
<ul>
<li>I am creating a custom rendered control (i.e. inherits from WebControl).</li>
<li>We are not using existnig Web Controls since we want complete control over the rendered output.</li>
<li>AFAIK the only way to get a server side event to occur from a custom rendered control is to call doPostBack from the rendered elements (please correct if wrong!).</li>
<li>ASP.NET MVC is not an option.</li>
</ul>

58,831 | <p>My boss found a bug in a query I created, and I don't understand the reasoning behind the bug, although the query results prove he's correct. Here's the query (simplified version) before the fix:</p>
<pre><code>select PTNO,PTNM,CATCD
from PARTS
left join CATEGORIES on (CATEGORIES.CATCD=PARTS.CATCD);
</code></pre>
<p>and here it is after the fix:</p>
<pre><code>select PTNO,PTNM,PARTS.CATCD
from PARTS
left join CATEGORIES on (CATEGORIES.CATCD=PARTS.CATCD);
</code></pre>
<p>The bug was, that null values were being shown for column CATCD, i.e. the query results included results from table CATEGORIES instead of PARTS.
Here's what I don't understand: if there was ambiguity in the original query, why didn't Oracle throw an error? As far as I understood, in the case of left joins, the "main" table in the query (PARTS) has precedence in ambiguity.
Am I wrong, or just not thinking about this problem correctly?</p>
<p>Update:</p>
<p>Here's a revised example, where the ambiguity error is not thrown:</p>
<pre><code>CREATE TABLE PARTS (PTNO NUMBER, CATCD NUMBER, SECCD NUMBER);
CREATE TABLE CATEGORIES(CATCD NUMBER);
CREATE TABLE SECTIONS(SECCD NUMBER, CATCD NUMBER);
select PTNO,CATCD
from PARTS
left join CATEGORIES on (CATEGORIES.CATCD=PARTS.CATCD)
left join SECTIONS on (SECTIONS.SECCD=PARTS.SECCD) ;
</code></pre>
<p>Anybody have a clue?</p>

<p>The result sets returned by the procedures are not the same data types or number of columns.</p>

59,007 | <p>I'd like to automate TortoiseSVN as part of a commit process.
Specifically I'd like to dynamically create a log entry for the commit dialog.</p>
<p>I know that I can launch the commit dialog either from the commandline or by right clicking on a folder and selecting svncommit.</p>
<p>I'd like to use the start commit hook to setup a log entry.
I thought this worked by passing an entry file name in the MESSAGEFILE variable but when I add a hook script it cannot see this variable (hook launched successfully after right clicking and choosing svncommit).</p>
<p>When I try using the commandline I use the /logmsgfile parameter but it seems to have no effect.</p>
<p>I'm using tortoisesvn 1.5.3.</p>

59,013 | <p>Context:
I'm in charge of running a service written in .NET. Proprietary application. It uses a SQL Server database. It ran as a user member of the Administrators group in the local machine. It worked alright before I added the machine to a domain.</p>
<p>So, I added the machine to a domain (Win 2003) and changed the user to a member of the Power Users group and now, the</p>
<p>Problem:
Some of the SQL sentences it tries to execute are "magically" in spanish localization (where , separates floating point numbers instead of .), leading to errors. </p>
<blockquote>
<p>There are fewer columns in the INSERT
statement than values specified in the
VALUES clause. The number of values in
the VALUES clause must match the
number of columns specified in the
INSERT statement. at
System.Data.SqlClient.SqlConnection.OnError(SqlException
exception, Boolean breakConnection)</p>
</blockquote>
<p>Operating System and Regional Settings in the machine are in English. I asked the provider of the application and he said:</p>
<blockquote>
<p>Looks like you have a combination of
code running under Spanish locale, and
SQL server under English locale. So
the SQL expects '15.28' and not
'15,28'</p>
</blockquote>
<p>Which looks wrong to me in various levels (how can SQL Server distinguish between commas to separate arguments and commas belonging to a floating point number?).</p>
<p>So, the code seems to be grabbing the spanish locale from somewhere, I don't know if it's the user it runs as, or someplace else (global policy, maybe?). But the question is</p>
<p>What are the places where localization is defined on a machine/user/domain basis?</p>
<p>I don't know all the places I must search for the culprit, so please help me to find it!</p>

59,083 | <h2>Question</h2>
<p>Alright, I'm confused by all the buzzwords and press release bingo going on.</p>
<ul>
<li>What is the relationship between flash and flex:
<ul>
<li>Replace flash (not really compatible)</li>
<li>Enhance flash</li>
<li>The next version of flash but still basically compatible</li>
<li>Separate technology altogether</li>
<li>???</li>
</ul></li>
<li>If I'm starting out in Flash now, should I just skip to Flex?</li>
</ul>
<h2>Follow up</h2>
<p>Ok, so what I'm hearing is that there's three different parts to the puzzle:</p>
<ul>
<li><strong>Flash</strong>
<ul>
<li>The graphical editor used to make "Flash Movies", ie it's an IDE that focuses on the visual aspect of "Flash" (Officially Flash CS3?)</li>
<li>The official name for the display plugins (ie, "Download Flash Now!")</li>
<li>A general reference to the entire technology stack</li>
<li>In terms of the editor, it's a linear timeline based editor, best used for animations with complex interactivity.</li>
</ul></li>
<li><strong>Actionscript</strong>
<ul>
<li>The "Flash" programming language</li>
</ul></li>
<li><strong>Flex</strong>
<ul>
<li>An Adobe Flash IDE that focuses on the coding/programming aspect of "Flash" (Flex Builder?)</li>
<li>A Flash library that enhances Flash and makes it easier to <em>program</em> for (Flex SDK?)</li>
<li>Is not bound to a timeline (as the Flash IDE is) and so "standard" applications are more easily accomplished.</li>
</ul></li>
</ul>
<p>Is this correct?</p>

59,098 | <p>We have some Win32 console applications running on Windows Server 2003 Service Pack 2 that regularly fail with this:</p>
<blockquote>
<p>Error 1450 (<code>ERROR_NO_SYSTEM_RESOURCES</code>): "Insufficient system resources exist to complete the requested service."</p>
</blockquote>
<p>All the documentation we've found suggests it is linked to the number of <strong>Free System Page Table Entries</strong> running out. We have 16GB RAM in these machines and use the <code>/3GB</code> Operating System switch to squeeze the Windows kernel into 1GB and allow our processes access to 3GB of address space. This drastically reduces the total number of Free System Page Table Entries, so combined with our heavy use of MapViewOfFile() it is perhaps not surprising that the kernel page table entries are running out.</p>
<p>However, when using Performance Monitor to view the Free System Page Table Entries counter, the value is around 36,000 on reboot and <strong>doesn't go down when our application starts</strong>. I find it hard to believe that our application, which opens many large memory-mapped files, doesn't have any effect on the kernel page table. If we can't believe the counter, it's much more difficult to test the effect of any system changes we make.</p>
<p>There is a promising Knowledge Base article, <a href="http://support.microsoft.com/kb/894067" rel="nofollow noreferrer">The Performance tool does not accurately show the available Free System Page Table entries in Windows Server 2003</a>, but it says the problem has been fixed in Service Pack 1, and we are already on Service Pack 2.</p>
<p>Has anyone else struggled with or solved this issue?</p>
<p><strong>Update:</strong> I have checked !sysptes in windbg (debugging the kernel) and the value matches the performance counter, around 36,000. I guess this is most likely to mean that there really are that many free page table entries and Windows <em>is</em> telling the truth. It does leave the question of why we're getting 1450 errors though, if the PTEs are not running out.</p>
<p><strong>Further update:</strong> We never did get to the bottom of why the 1450 errors were occurring. <em>However</em>, instead we upgraded the OS on these servers to 64-bit Windows. This allows the existing 32-bit applications (without recompilation) to access a full 4GB of virtual address space, and lets the kernel memory area with those pesky Page Table Entries be as big as it likes too. I don't think we've had a 1450 error since.</p>

59,102 | <p>Let's say that I'm writing a function to convert between temperature scales. I want to support at least Celsius, Fahrenheit, and Kelvin. Is it better to pass the source scale and target scale as separate parameters of the function, or some sort of combined parameter?</p>
<p>Example 1 - separate parameters:
function convertTemperature("celsius", "fahrenheit", 22)</p>
<p>Example 2 - combined parameter:
function convertTemperature("c-f", 22)</p>
<p>The code inside the function is probably where it counts. With two parameters, the logic to determine what formula we're going to use is slightly more complicated, but a single parameter doesn't feel right somehow.</p>
<p>Thoughts?</p>

59,105 | <p>Almost 5 years ago Joel Spolsky wrote this article, <a href="http://www.joelonsoftware.com/articles/Unicode.html" rel="nofollow noreferrer">"The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)"</a>.</p>
<p>Like many, I read it carefully, realizing it was high-time I got to grips with this "replacement for ASCII". Unfortunately, 5 years later I feel I have slipped back into a few bad habits in this area. Have you?</p>
<p>I don't write many specifically international applications, however I have helped build many ASP.NET internet facing websites, so I guess that's not an excuse. </p>
<p>So for my benefit (and I believe many others) can I get some input from people on the following:</p>
<ul>
<li>How to "get over" ASCII once and for all</li>
<li>Fundamental guidance when working with Unicode.</li>
<li>Recommended (recent) books and websites on Unicode (for developers). </li>
<li>Current state of Unicode (5 years after Joels' article) </li>
<li>Future directions.</li>
</ul>
<p>I must admit I have a .NET background and so would also be happy for information on Unicode in the .NET framework. Of course this shouldn't stop anyone with a differing background from commenting though.</p>
<p>Update: See <a href="https://stackoverflow.com/questions/898/internationalization-in-your-projects">this related question</a> also asked on StackOverflow previously.</p>

59,107 | <p>I'm converting an application to use Java 1.5 and have found the following method:</p>
<pre><code> /**
* Compare two Comparables, treat nulls as -infinity.
* @param o1
* @param o2
* @return -1 if o1&lt;o2, 0 if o1==o2, 1 if o1&gt;o2

} else {
return -1;
}
} else if (o2 == null) {
return 1;
} else {
return o1.compareTo(o2);
}
}
</code></pre>
<p>Ideally I would like to make the method take two Comparables of the same type, is it possible to convert this and how? </p>
<p>I thought the following would do the trick:</p>
<pre><code>protected static <T extends Comparable> int nullCompare(T o1, T o2) {
</code></pre>
<p>but it has failed to get rid of a warning in IntelliJ "Unchecked call to 'compareTo(T)' as a member of raw type 'java.lang.Comparable'" on the line:</p>
<pre><code>return o1.compareTo(o2);
</code></pre>

<p>The resulting page just contains the grid and it's contents - however I would like to add a header or title to identify the printed report, and possibly a footer to show who printed it, when, and ideally a page number and total pages.</p>
<p>I'm using VB.Net 2.0.</p>
<p>Thanks for your help!</p>

59,217 | <p>Is there a built in function in .NET 2.0 that will take two arrays and merge them into one array?</p>
<p>The arrays are both of the same type. I'm getting these arrays from a widely used function within my code base and can't modify the function to return the data in a different format.</p>
<p>I'm looking to avoid writing my own function to accomplish this if possible.</p>

59,220 | <p>I'm writing a utility for myself, partly as an exercise in learning C# Reflection and partly because I actually want the resulting tool for my own use.</p>
<p>What I'm after is basically pointing the application at an assembly and choosing a given class from which to select properties that should be included in an exported HTML form as fields. That form will be then used in my ASP.NET MVC app as the beginning of a View.</p>
<p>As I'm using Subsonic objects for the applications where I want to use, this should be reasonable and I figured that, by wanting to include things like differing output HTML depending on data type, Reflection was the way to get this done.</p>
<p>What I'm looking for, however, seems to be elusive. I'm trying to take the DLL/EXE that's chosen through the OpenFileDialog as the starting point and load it:</p>
<pre><code>String FilePath = Path.GetDirectoryName(FileName);
System.Reflection.Assembly o = System.Reflection.Assembly.LoadFile(FileName);
</code></pre>
<p>That works fine, but because Subsonic-generated objects actually are full of object types that are defined in Subsonic.dll, etc., those dependent objects aren't loaded. Enter:</p>
<pre><code>AssemblyName[] ReferencedAssemblies = o.GetReferencedAssemblies();
</code></pre>
<p>That, too, contains exactly what I would expect it to. However, what I'm trying to figure out is how to load those assemblies so that my digging into my objects will work properly. I understand that if those assemblies were in the GAC or in the directory of the running executable, I could just load them by their name, but that isn't likely to be the case for this use case and it's my primary use case.</p>
<p>So, what it boils down to is how do I load a given assembly and all of its arbitrary assemblies starting with a filename and resulting in a completely Reflection-browsable tree of types, properties, methods, etc.</p>
<p>I know that tools like Reflector do this, I just can't find the syntax for getting at it. </p>

59,221 | <p>I am using ActiveScaffold in a Ruby on Rails app, and to save space in the table I have replaced the default "actions" text in the table (ie. "edit", "delete", "show") with icons using CSS. I have also added a couple of custom actions with action_link.add ("move" and "copy").</p>
<p>For clarity, <strong>I would like to have a tooltip pop up with the related action</strong> (ie. "edit", "copy") when I hover the mouse over the icon.</p>
<p>I thought I could do this by adding a simple "alt" definition to the tag, but that doesn't appear to work.</p>
<p>Can somebody point me in the right direction?</p>

59,280 | <p>I need to update a <code>combobox</code> with a new value so it changes the reflected text in it. The cleanest way to do this is after the <code>combobox</code>has been initialised and with a message.</p>
<p>So I am trying to craft a <code>postmessage</code> to the hwnd that contains the <code>combobox</code>.</p>
<p>So if I want to send a message to it, changing the currently selected item to the nth item, what would the <code>postmessage</code> look like?</p>
<p>I am guessing that it would involve <code>ON_CBN_SELCHANGE</code>, but I can't get it to work right.</p>

group by column_name

<p>What would be the difference if I replaced all calls to <code>count(column_name)</code> to <code>count(*)</code>?</p>

<hr>
<p>To clarify the accepted answer (and maybe my question), replacing <code>count(column_name)</code> with <code>count(*)</code> would return an extra row in the result that contains a <code>null</code> and the count of <code>null</code> values in the column.</p>

59,309 | <p>What is the best way to vertically center the content of a div when the height of the content is variable. In my particular case, the height of the container div is fixed, but it would be great if there were a solution that would work in cases where the container has a variable height as well. Also, I would love a solution with no, or very little use of CSS hacks and/or non-semantic markup.</p>

59,331 | <p>Suppose I have <code>fileA.h</code> which declares a class <code>classA</code> with template function <code>SomeFunc<T>()</code>. This function is implemented directly in the header file (as is usual for template functions). Now I add a specialized implementation of <code>SomeFunc()</code> (like for <code>SomeFunc<int>()</code>) in <code>fileA.C</code> (ie. not in the header file).</p>
<p>If I now call <code>SomeFunc<int>()</code> from some other code (maybe also from another library), would it call the generic version, or the specialization?</p>
<p>I have this problem right now, where the class and function live in a library which is used by two applications. And one application correctly uses the specialization, while another app uses the generic form (which causes runtime problems later on). Why the difference? Could this be related to linker options etc? This is on Linux, with g++ 4.1.2.</p>

59,357 | <p><strong>Edit</strong>: Let me completely rephrase this, because I'm not sure there's an XML way like I was originally describing.</p>
<p><strong>Yet another edit</strong>: This needs to be a repeatable process, and it has to be able to be set up in a way that it can be called in C# code.</p>
<p>In database A, I have a set of tables, related by PKs and FKs. A parent table, with child and grandchild tables, let's say.</p>
<p>I want to <strong>copy a set of rows from database A to database B</strong>, which has identically named tables and fields. For each table, I want to insert into the same table in database B. But I can't be constrained to use the same primary keys. <strong>The copy routine must create new PKs</strong> for each row in database B, and must propagate those to the child rows. I'm keeping the same relations between the data, in other words, but not the same exact PKs and FKs.</p>
<p>How would you solve this? I'm open to suggestions. SSIS isn't completely ruled out, but it doesn't look to me like it'll do this exact thing. I'm also open to a solution in LINQ, or using typed DataSets, or using some XML thing, or just about anything that'll work in SQL Server 2005 and/or C# (.NET 3.5). The best solution wouldn't require SSIS, and wouldn't require writing a lot of code. But I'll concede that this "best" solution may not exist.</p>
<p>(I didn't make this task up myself, nor the constraints; this is how it was given to me.)</p>

When you call TransactionDao.Save(transaction) I would like for it to setting a transaction.IsSaved=true flag (this is a simplification the actual thing I'm trying to do is not quite so banal).

Expect.Call(delegate {dao.Save(t); }).Do( new FakeSave(delegate(Transaction t2) { t.IsSaved = true; }));
