56,950 | <p>We all know T-SQL's string manipulation capabilities sometimes leaves much to be desired...</p>
<p>I have a numeric field that needs to be output in T-SQL as a right-aligned text column. Example:</p>
<pre><code>Value
----------
143.55
3532.13
1.75
</code></pre>
<p>How would you go about that? A good solution ought to be clear and compact, but remember there is such a thing as "too clever".</p>
<p>I agree this is the wrong place to do this, but sometimes we're stuck by forces outside our control.</p>
<p>Thank you.</p>

56,968 | <p>I'm trying to attach an instance of UIScrollbar component to a dynamic text field inside of an instance of a class that is being made after some XML is loaded. The scroll bar component is getting properly attached, as the size of the slider varies depending on the amount of content in the text field, however, it won't scroll.</p>
<p>Here's the code:</p>
<pre><code>function xmlLoaded(evt:Event):void
{
//do some stuff
for(var i:int = 0; i < numProfiles; i++)
{
var thisProfile:profile = new profile();
thisProfile.alpha = 0;
thisProfile.x = 0;
thisProfile.y = 0;
thisProfile.name = "profile" + i;
profilecontainer.addChild(thisProfile);
thisProfile.profiletextholder.profilename.htmlText = profiles[i].attribute("name");
thisProfile.profiletextholder.profiletext.htmlText = profiles[i].profiletext;
//add scroll bar
var vScrollBar:UIScrollBar = new UIScrollBar();
vScrollBar.direction = ScrollBarDirection.VERTICAL;
vScrollBar.move(thisProfile.profiletextholder.profiletext.x + thisProfile.profiletextholder.profiletext.width, thisProfile.profiletextholder.profiletext.y);
vScrollBar.height = thisProfile.profiletextholder.profiletext.height;
vScrollBar.scrollTarget = thisProfile.profiletextholder.profiletext;
vScrollBar.name = "scrollbar";
vScrollBar.update();
vScrollBar.visible = (thisProfile.profiletextholder.profiletext.maxScrollV > 1);
thisProfile.profiletextholder.addChild(vScrollBar);
//do some more stuff
}
}
</code></pre>
<p>I've also tried it with a UIScrollBar component within the movieclip/class itself, and it still doesn't work. Any ideas?</p>

57,010 | <p>Please, now that I've re-written the question, and before it suffers from further <a href="https://stackoverflow.com/questions/56103/fastest-gun-in-the-west-problem">fast-gun answers</a> or premature closure by <a href="https://stackoverflow.com/users/905/keith">eager editors</a> let me point out that this is not a duplicate of <a href="https://stackoverflow.com/questions/9673/remove-duplicates-from-array">this question</a>. I know how to remove duplicates from an array.</p>
<p>This question is about removing <strong>sequences</strong> from an array, not duplicates in the strict sense.</p>
<p>Consider this sequence of elements in an array;</p>
<pre><code>[0] a
[1] a
[2] b
[3] c
[4] c
[5] a
[6] c
[7] d
[8] c
[9] d
</code></pre>
<p>In this example I want to obtain the following...</p>
<pre><code>[0] a
[1] b
[2] c
[3] a
[4] c
[5] d
</code></pre>
<p>Notice that duplicate elements are retained but that sequences of the same element have been reduced to a single instance of that element.</p>
<p>Further, notice that when two lines repeat they should be reduced to one set (of two lines).</p>
<pre><code>[0] c
[1] d
[2] c
[3] d
</code></pre>
<p>...reduces to...</p>
<pre><code>[0] c
[1] d

57,020 | <p>Was considering the <code>System.Collections.ObjectModel ObservableCollection<T></code> class. This one is strange because </p>
<ul>
<li>it has an Add Method which takes <strong>one</strong> item only. No AddRange or equivalent. </li>
<li>the Notification event arguments has a NewItems property, which is a <strong>IList</strong> (of objects.. not T)</li>
</ul>
<p>My need here is to add a batch of objects to a collection and the listener also gets the batch as part of the notification. Am I missing something with ObservableCollection ? Is there another class that meets my spec?</p>
<p><em>Update: Don't want to roll my own as far as feasible. I'd have to build in add/remove/change etc.. a whole lot of stuff.</em></p>

57,053 | <p>I am writing some software to identify tracking numbers (in the same way that Google identifies FedEx or UPS numbers when you search for them). Most couriers use a system, such as a "weighted average mod system" which can be used to identify if a number is a valid tracking number. Does anyone know if TNT consignment numbers use such a system, and if so, what it is? I have asked TNT support, and the rep told me they do not... but I'd like to doublecheck.</p>

57,054 | <p>I've got a collection that implements an interface that extends both IList<T> and List. </p>
<pre><code>public Interface IMySpecialCollection : IList<MyObject>, IList { ... }
</code></pre>
<p>That means I have two versions of the indexer. </p>
<p>I wish the generic implementation to be used, so I implement that one normally:</p>
<pre><code>public MyObject this[int index] { .... }
</code></pre>
<p>I only need the IList version for serialization, so I implement it explicitly, to keep it hidden:</p>
<pre><code>object IList.this[int index] { ... }
</code></pre>
<p>However, in my unit tests, the following</p>
<pre><code>MyObject foo = target[0];
</code></pre>
<p>results in a compiler error</p>
<blockquote>
<p>The call is ambiguous between the
following methods or properties</p>
</blockquote>
<p>I'm a bit surprised at this; I believe I've done it before and it works fine. What am I missing here? How can I get IList<T> and IList to coexist within the same interface?</p>
<p><strong>Edit</strong> IList<T> does <em>not</em> implement IList, and I <strong>must</strong> implement IList for serialization. I'm not interested in workarounds, I want to know what I'm missing.</p>
<p><strong>Edit again</strong>: I've had to drop IList from the interface and move it on my class. I don't want to do this, as classes that implement the interface are eventually going to be serialized to Xaml, which requires collections to implement IDictionary or IList...</p>

57,091 | <p>Let's say I have a parent DIV. Inside, there are three child DIVs: header, content and footer. Header is attached to the top of the parent and fills it horizontally. Footer is attached to the bottom of the parent and fills it horizontally too. Content is supposed to fill all the space between header and footer.</p>
<p>The parent has to have a fixed width and height. The content DIV has to fill all available space between header and footer. When the content size of the content DIV exceeds the space between header and footer, <strong><em>the content DIV should display scrollbars and allow appropriate scrolling</em></strong> so that the footer contents should never be obscured nor the footer obscure content.</p>
<p>Now comes the hard part: <strong><em>you don't know the height of the header nor footer beforehand</em></strong> (eg. header and footer are filled dynamically). How can content be positioned <strong><em>without using JavaScript</em></strong>?</p>
<p>Example:</p>
<pre><code><div style="position : relative; width : 200px; height : 200px; background-color : #e0e0ff; overflow : hidden;">
<div style="background-color: #80ff80; position : absolute; left : 0; right : 0; top : 0;">
header
</div>
<div style="background-color: #8080ff; overflow : auto; position : absolute;">
content (how to position it?)
</div>
<div style="background-color: #ff8080; position : absolute; bottom : 0px; left :0; right : 0;">
footer
</div>
</div>
</code></pre>
<hr>
<p><strong>To clarify this event further</strong> - the target layout that I'm trying to achieve will be used in a business web application. <strong><em>The parent DIV will have a fixed, but unknown size</em></strong> (for instance, it will be exactly the size of the browser viewport, sizing itself along with sizing the browser window by the user). Let's call the parent DIV a "screen".</p>
<p>The header will contain a set of filtering controls (like textboxes, drop down lists and a "filter" button) that should wrap to the next line if there is insufficient horizontal space (so its height can change any time to accomodate line breaking). <strong><em>The header should always be visible and attached to the top</em></strong> of the "screen".</p>
<p>The footer will contain a set of buttons, like on a dialog window. These too can wrap to next line if there is not enough space horizontally. <strong><em>The footer must be attached to the bottom</em></strong> of the "screen" to be accessible and visible at all times.</p>
<p>The content will contain "screen" contents, like dialog fields etc. If there are too few fields, the rest of the content will be "blank" (in this case the footer should not begin right after the content, but still be attached to the bottom of the "screen" which is fixed size). If there are too many fields, <strong><em>the content DIV will provide scrollbar(s)</em></strong> to access the hidden controls (in this case the content DIV must not extend itself below the footer, as the scrollbar would be partially hidden). </p>
<p>I hope this clarifies the question a little bit further, as I have too low rep to enter comments to your repsonses.</p>

57,104 | <p>I'm going to be starting a project soon that requires support for large-ish binary files. I'd like to use Ruby on Rails for the webapp, but I'm concerned with the BLOB support. In my experience with other languages, frameworks, and databases, BLOBs are often overlooked and thus have poor, difficult, and/or buggy functionality.</p>
<p>Does RoR spport BLOBs adequately? Are there any gotchas that creep up once you're already committed to Rails?</p>
<p>BTW: I want to be using PostgreSQL and/or MySQL as the backend database. Obviously, BLOB support in the underlying database is important. For the moment, I want to avoid focusing on the DB's BLOB capabilities; I'm more interested in how Rails itself reacts. Ideally, Rails should be hiding the details of the database from me, and so I should be able to switch from one to the other. If this is <em>not</em> the case (ie: there's some problem with using Rails with a particular DB) then please do mention it. </p>
<p>UPDATE: Also, I'm not just talking about ActiveRecord here. I'll need to handle binary files on the HTTP side (file upload effectively). That means getting access to the appropriate HTTP headers and streams via Rails. I've updated the question title and description to reflect this.</p>

57,124 | <p>I know I can call the GetVersionEx Win32 API function to retrieve Windows version. In most cases returned value reflects the version of my Windows, but sometimes that is not so.</p>
<p>If a user runs my application under the compatibility layer, then GetVersionEx won't be reporting the real version but the version enforced by the compatibility layer. For example, if I'm running Vista and execute my program in "Windows NT 4" compatibility mode, GetVersionEx won't return version 6.0 but 4.0.</p>
<p>Is there a way to bypass this behaviour and get true Windows version?</p>

57,140 | <p>Say instead of returning void a method you returned a reference to the class even if it didn't make any particular semantic sense. It seems to me like it would give you more options on how the methods are called, allowing you to use it in a fluent-interface-like style and I can't really think of any disadvantages since you don't have to do anything with the return value (even store it).</p>
<p>So suppose you're in a situation where you want to update an object and then return its current value.
instead of saying </p>
<pre><code>myObj.Update();
var val = myObj.GetCurrentValue();
</code></pre>
<p>you will be able to combine the two lines to say</p>
<pre><code>var val = myObj.Update().GetCurrentValue();
</code></pre>
<hr>
<p><strong>EDIT:</strong> I asked the below on a whim, in retrospect, I agree that its likely to be unnecessary and complicating, however my question regarding returning this rather than void stands.</p>
<p>On a related note, what do you guys think of having the language include a new bit of syntactic sugar:</p>
<pre><code>var val = myObj.Update()<.GetCurrentValue();
</code></pre>
<p>This operator would have a low order of precedence so myObj.Update() would execute first and then call GetCurrentValue() on myObj instead of the void return of Update.</p>
<p>Essentially I'm imagining an operator that will say "call the method on the right-hand side of the operator on the first valid object on the left". Any thoughts?</p>

57,145 | <p>While creating classes in Java I often find myself creating instance-level collections that I know ahead of time will be very small - less than 10 items in the collection. But I don't know the number of items ahead of time so I typically opt for a dynamic collection (ArrayList, Vector, etc).</p>
<pre><code>class Foo
{
ArrayList<Bar> bars = new ArrayList<Bar>(10);
}
</code></pre>
<p>A part of me keeps nagging at me that it's wasteful to use complex dynamic collections for something this small in size. Is there a better way of implementing something like this? Or is this the norm?</p>
<p>Note, I'm not hit with any (noticeable) performance penalties or anything like that. This is just me wondering if there isn't a better way to do things.</p>

<pre><code>PK = primary key
FK = foreign key
NU = nullable
</code></pre>
<p>One table with many nullalbe fields (flat file)…</p>
<pre><code> Alphas
--------
PK AlphaId
AlphaOne
AlphaTwo
AlphaThree
NU BravoOne
NU BravoTwo
NU BravoThree
NU CharlieOne
NU CharlieTwo
NU CharlieThree
</code></pre>
<p>Many tables with zero nullalbe fields…</p>
<pre><code> Alphas
--------
PK AlphaId
AlphaOne
AlphaTwo
AlphaThree
Bravos
--------
FK PK AlphaId
BravoOne
BravoTwo
BravoThree
Charlies
--------
FK PK AlphaId
CharlieOne
CharlieTwo
CharlieThree
</code></pre>
<p>Best (or worst) of both: Lots of nullalbe foreign keys to many tables…</p>
<pre><code> Alphas
--------
PK AlphaId
AlphaOne
AlphaTwo
AlphaThree
NU FK BravoId
NU FK CharlieId
Bravos
--------
PK BravoId
BravoOne
BravoTwo
BravoThree
Charlies
--------
PK CharlieId
CharlieOne
CharlieTwo
CharlieThree
</code></pre>
<p>What if an Alpha must be either Bravo or Charlie, but not both?</p>
<p>What if instead of just Bravos and Charlies, Alphas could also be any of Deltas, Echos, Foxtrots, or Golfs, etc…?</p>

57,243 | <p>I am trying to do something I've done a million times and it's not working, can anyone tell me why?</p>
<p>I have a table for people who sent in resumes, and it has their email address in it...</p>
<p>I want to find out if any of these people have NOT signed up on the web site. The aspnet_Membership table has all the people who ARE signed up on the web site.</p>
<p>There are 9472 job seekers, with unique email addresses.</p>
<p>This query produces 1793 results:</p>
<pre><code>select j.email from jobseeker j
join aspnet_Membership m on j.email = m.email
</code></pre>
<p>This suggests that there should be 7679 (9472-1793) emails of people who are not signed up on the web site. Since 1793 of them DID match, I would expect the rest of them DON'T match... but when I do the query for that, I get nothing!</p>
<p>Why is this query giving me nothing???</p>
<pre><code>select j.email
from jobseeker j
where j.email not in (select email from aspnet_Membership)
</code></pre>
<p>I don't know how that could be not working - it basically says "show me all the emails which are IN the jobseeker table, but NOT IN the aspnet_Membership table... </p>

57,314 | <p>What could the best strategy for writing validation layer for mid-enterprise level business application built on Spring 2.5</p>
<p>I know that Spring provides facility where we can implement Validator interface and write validation logic in validate method. But this will be restricted to only web requests coming through spring controller.</p>
<p>I would like to develop the validation framework which can be utilized during web-services calls.</p>
<p>In other words, the framework can remain and be called independently without the need of implementing Validator interface and then too it can be automatically integrated into Spring MVC flow.</p>
<p>Hope you get my point.</p>

<pre><code>struct Widget
{
Widget():x(0), y(0), z(0){}
int x, y, z;
};
struct WidgetHolder //Just a simple struct to hold four Widgets.
{
WidgetHolder(Widget a, Widget b, Widget c, Widget d): A(a), B(b), C(c), D(d){}
Widget& A;
Widget& B;
Widget& C;
Widget& D;
};
class Test //This class uses four widgets internally, and must provide access to them externally.
{
public:
const WidgetHolder AccessWidgets() const
{
//This should return our four widgets, but I don't want anyone messing with them.
return WidgetHolder(A, B, C, D);
}
WidgetHolder AccessWidgets()
{
//This should return our four widgets, I don't care if they get changed.
return WidgetHolder(A, B, C, D);
}
private:
Widget A, B, C, D;
};
int main()
{
const Test unchangeable;
unchangeable.AccessWidgets().A.x = 1; //Why does this compile, shouldn't the Widget& be const?
}
</code></pre>
<p>Basically, I have a class called test. It uses four widgets internally, and I need it to return these, but if test was declared const, I want the widgets returned const also.</p>
<p>Can someone explain to me why the code in main() compiles?</p>
<p>Thank you very much.</p>

57,439 | <p>No, this is not a question about generics.</p>
<p>I have a Factory pattern with several classes with internal constructors (I don't want them being instantiated if not through the factory).</p>
<p>My problem is that <code>CreateInstance</code> fails with a "No parameterless constructor defined for this object" error unless I pass "true" on the non-public parameter.</p>
<p>Example</p>
<pre><code>// Fails
Activator.CreateInstance(type);
// Works
Activator.CreateInstance(type, true);
</code></pre>
<p>I wanted to make the factory generic to make it a little simpler, like this:</p>
<pre><code>public class GenericFactory<T> where T : MyAbstractType
{
public static T GetInstance()
{
return Activator.CreateInstance<T>();
}
}
</code></pre>
<p>However, I was unable to find how to pass that "true" parameter for it to accept non-public constructors (internal).</p>
<p>Did I miss something or it isn't possible?</p>

57,479 | <p>Help! I am using jQuery to make an AJAX call to fill in a drop-down dynamically given the user's previous input (from another drop-down, that is filled server-side). In all other browsers aside from Firefox (IE6/7, Opera, Safari), my append call actually appends the information below my existing option - "Select An ". But in Firefox, it automatically selects the last item given to the select control, regardless of whether I specify the JQuery action to .append or to replace (.html()). </p>
<pre><code><select name="Products" id="Products" onchange="getHeadings(this.value);">
<option value="">Select Product</option>
</select>
function getProducts(Category) {
$.ajax({
type: "GET",
url: "getInfo.cfm",
data: "Action=getProducts&Category=" + Category,
success: function(result){
$("#Products").html(result);
}
});
};
</code></pre>
<p>Any thoughts? I have tried in the past to also transmit another blank first option, and then trigger a JavaScript option to re-select the first index, but this triggers the onChange event in my code, rather annoying for the user.</p>

57,493 | <p>In my WPF application, I have a number of databound TextBoxes. The <code>UpdateSourceTrigger</code> for these bindings is <code>LostFocus</code>. The object is saved using the File menu. The problem I have is that it is possible to enter a new value into a TextBox, select Save from the File menu, and never persist the new value (the one visible in the TextBox) because accessing the menu does not remove focus from the TextBox. How can I fix this? Is there some way to force all the controls in a page to databind?</p>
<p><em>@palehorse: Good point. Unfortunately, I need to use LostFocus as my UpdateSourceTrigger in order to support the type of validation I want.</em></p>
<p><em>@dmo: I had thought of that. It seems, however, like a really inelegant solution for a relatively simple problem. Also, it requires that there be some control on the page which is is always visible to receive the focus. My application is tabbed, however, so no such control readily presents itself.</em></p>
<p><em>@Nidonocu: The fact that using the menu did not move focus from the TextBox confused me as well. That is, however, the behavior I am seeing. The following simple example demonstrates my problem:</em></p>

57,522 | <p>I can create the following and reference it using</p>
<pre><code>area[0].states[0]
area[0].cities[0]
var area = [
{
"State" : "Texas",
"Cities" : ['Austin','Dallas','San Antonio']
},
{
"State" :"Arkansas",
"Cities" : ['Little Rock','Texarkana','Hot Springs']

</code></pre>
<p>How could I restructure "area" so that if I know the name of the state, I can use it in a reference to get the array of cities?</p>
<p>Thanks</p>
<p><strong>EDIT</strong> Attempting to implement with the answers I received (thanks @Eli Courtwright, @17 of 26, and @JasonBunting) I realize my question was incomplete. I need to loop through "area" the first time referencing "state" by index, then when I have the selection of the "state", I need to loop back through a structure using the value of "state" to get the associated "cities". I do want to start with the above structure (although I am free to build it how I want) and I don't mind a conversion similar to @eli's answer (although I was not able to get that conversion to work). Should have been more complete in first question. Trying to implement 2 select boxes where the selection from the first populates the second...I will load this array structure in a js file when the page loads.</p>

57,552 | <p>Ok, so I got my extender working on a default.aspx page on my website and it looks good. I basically copied and pasted the code for it into a user control control.ascx page. When I do this I completely loose the functionality (just shows the target control label and no dropdown, even upon hover). Is there any reason why it doesn't work in a custom user control inside a masterpage setup?</p>
<p>Edit:
Didn't quite do the trick. Any other suggestions?
Its in a master page setup, using eo web tabs (I tried it inside the tabs and outside the tabs but on the same page as the tabs, to no avail), and its in a custom user control. Think there are dependency issues?</p>

57,609 | <p>I'm working on a WinCE 6.0 system with a touchscreen that stores its calibration data (x-y location, offset, etc.) in the system registry (HKLM\HARDWARE\TOUCH). Right now, I'm placing the cal values into registry keys that get put into the OS image at build time. That works fine for the monitor that I get the original cal values from, but when I load this image into another system with a different monitor, the touchscreen pointer location is (understandably) off, because the two monitors do not have the same cal values.</p>
<p>My problem is that I don't know how to properly store values into the registry so that they persist after a power cycle. See, I can recalibrate the screen on the second system, but the new values only exist in volatile memory. I suggested to my boss that we could just tell our customer to leave the power on the unit at all times -- that didn't go over well.</p>
<p>I need advice on how to save the new constants into the registry, so that we can calibrate the monitors once before shipping them out to our customer, and not have to make separate OS images for each unit we build.</p>
<p>A C# method that is known to work in CE6.0 would be helpful. Thanks.</p>

57,625 | <p>This one will take some explaining. What I've done is create a specific custom message queue in SQL Server 2005. I have a table with messages that contain timestamps for both acknowledgment and completion. The stored procedure that callers execute to obtain the next message in their queue also acknowledges the message. So far so good. Well, if the system is experiencing a massive amount of transactions (thousands per minute), isn't it possible for a message to be acknowledged by another execution of the stored procedure while another is prepared to so itself? Let me help by showing my SQL code in the stored proc:</p>
<pre><code>--Grab the next message id
declare @MessageId uniqueidentifier
set @MessageId = (select top(1) ActionMessageId from UnacknowledgedDemands);
--Acknowledge the message
update ActionMessages
set AcknowledgedTime = getdate()
where ActionMessageId = @MessageId
--Select the entire message
...
...
</code></pre>
<p>In the above code, couldn't another stored procedure running at the same time obtain the same id and attempt to acknowledge it at the same time? Could I (or should I) implement some sort of locking to prevent another stored proc from acknowledging messages that another stored proc is querying? </p>
<p>Wow, did any of this even make sense? It's a bit difficult to put to words...</p>

57,718 | <p>Has anyone actually shipped an Entity Framework project that does O/R mapping into conceptual classes that are quite different from the tables in the datastore?</p>
<p>I mean collapse junction (M:M) tables into other entities to form <strong>Conceptual</strong> classes that exist in the business domain but are organized as <strong>multiple tables</strong> in the datastore. All the examples that I see on the MSDN have little use of inheritance, collapsing junction tables into other entities, or collapsing lookup tables into entities.</p>
<p>I'd love to hear of or see examples of the below which support all the CRUD operations you would typically expect to do on a business object.:</p>
<ol>
<li><p>Vehicle table and a Color table. A Color can appear in many Vehicles (1:M). They form the conceptual class UsedCar which has the property Color. </p></li>
<li><p>Doctor, DoctorPatients, and Patients tables (form a many to many). Doctors have many Patients, Patients can have many Doctors (M:M). Map out the two conceptual classes Doctor (which has a Patients collection) and Patients (which has a Doctors collection).</p></li>
</ol>
<p><strong>Anyone seen/done this with CSDL AND SSDL in the Entity Framework? The CSDL is no good if it doesn't actaully map to anything!</strong></p>

57,725 | <p>Let's say I want a way to display just the the center 50x50px of an image that's 250x250px in HTML. How can I do that. Also, is there a way to do this for css:url() references?
<p>
I'm aware of <em>clip</em> in CSS, but that seems to only work when used with absolute positioning.</p>

57,751 | <p>I want to find any text in a file that matches a regexp of the form <em>t</em><code>[A-Z]</code><em>u</em> (i.e., a match <em>t</em> followed by a capital letter and another match <em>u</em>, and transform the matched text so that the capital letter is lowercase. For example, for the regexp <code>x[A-Z]y</code></p>
<pre><code>xAy
</code></pre>
<p>becomes</p>
<pre><code>xay
</code></pre>
<p>and</p>
<pre><code>xZy
</code></pre>
<p>becomes</p>
<pre><code>xzy
</code></pre>
<p>Emacs' <code>query-replace</code> function allows back-references, but AFAIK not the transformation of the matched text. Is there a built-in function that does this? Does anybody have a short Elisp function I could use?</p>
<p><strong>UPDATE</strong></p>
<p>@Marcel Levy has it: <code>\,</code> in a replacement expression introduces an (arbitrary?) Elisp expression. E.g., the solution to the above is</p>
<pre><code>M-x replace-regexp <RET> x\([A-Z]\)z <RET> x\,(downcase \1)z
</code></pre>

57,776 | <p>I have a free standing set of files not affiliated with any C# project at all that reside in a complicated nested directory structure.</p>
<p>I want to add them in that format to a different directory in an ASP.NET web application I am working on; while retaining the same structure. So, I copied the folder into the target location of my project and I tried to “add existing item” only to lose the previous folder hierarchy.</p>
<p>Usually I have re-created the directories by hand, copied across on a one-to-one basis, and then added existing items. There are simply too many directories/items in this case.</p>
<p>So how do you add existing directories and files in Visual Studio 2008?</p>

57,791 | <p>I have a page which does quite a bit of work and I don't want the user to be able to navigate away from that page (close browser, hit back button, etc.) without getting a warning. I found that the onbeforeunload event (which I think is IE-specific, which works fine for me as the project uses lots of ActiveX) works great.</p>
<p>Problem is, I want the user to be able to click on a little "help" icon in the upper-right corner and pop up a help window at any time. This causes onbeforeunload to fire, even though the main window never goes anywhere and the page never unloads. </p>
<p>The JavaScript function that runs when the onbeforeunload event runs just puts text into event.returnValue. If I could ascertain, somehow, that the help icon is the one that was clicked then I could just not put text into event.returnValue in that situation. But how could I have the page figure that out?</p>

57,845 | <p>Is it possible to use BackGroundWorker thread in <a href="http://en.wikipedia.org/wiki/ASP.NET" rel="nofollow noreferrer">ASP.NET</a> 2.0 for the following scenario, so that the user at the browser's end does not have to wait for long time?</p>
<h2>Scenario</h2>
<ol>
<li>The browser requests a page, say SendEmails.aspx</li>
<li>SendEmails.aspx page creates a BackgroundWorker thread, and supplies the thread with enough context to create and send emails.</li>
<li>The browser receives the response from the ComposeAndSendEmails.aspx, saying that emails are being sent.</li>
<li>Meanwhile, the background thread is engaged in a process of creating and sending emails which could take some considerable time to complete.</li>
</ol>
<p>My main concern is about keeping the BackgroundWorker thread running, trying to send, say 50 emails while the ASP.NET workerprocess threadpool thread is long gone.</p>

57,923 | <p>I've been writing C / C++ code for almost twenty years, and I know Perl, Python, PHP, and some Java as well, and I'm teaching myself JavaScript. But I've never done any .NET, VB, or C# stuff. What exactly does <strong>managed</strong> code mean?</p>
<p>Wikipedia <a href="http://en.wikipedia.org/wiki/Managed_code" rel="noreferrer">describes it</a> simply as</p>
<blockquote>
<p>Code that executes under the management of a virtual machine</p>
</blockquote>
<p>and it specifically says that Java is (usually) managed code, so</p>
<ul>
<li><strong>why does the term only seem to apply to C# / .NET?</strong></li>
<li><strong>Can you compile C# into a .exe that contains the VM as well, or do you have to package it up and give it to another .exe (a la java)?</strong></li>
</ul>
<p>In a similar vein,</p>
<ul>
<li><strong>is .NET a <em>language</em> or a <em>framework</em>, and what exactly does "framework" mean here?</strong></li>
</ul>
<p>OK, so that's more than one question, but for someone who's been in the industry as long as I have, I'm feeling rather N00B-ish right now...</p>

57,927 | <p>I have an excel spreadsheet in a format similar to the following...</p>
<pre><code>| NAME | CLUB | STATUS | SCORE |
| Fred | a | Gent | 145 |
| Bert | a | Gent | 150 |
| Harry | a | Gent | 195 |
| Jim | a | Gent | 150 |
| Clare | a | Lady | 99 |
| Simon | a | Junior | 130 |
| John | b | Junior | 130 |
:
:
| Henry | z | Gent | 200 |
</code></pre>
<p>I need to convert this table into a list of the "Top Ten" teams. The rules are</p>
<ul>
<li>Each team score is taken from the sum of four members of that club.</li>
<li>These totals should be of the best four scores except...
<ul>
<li>Each team must consist of at least one Junior or Lady</li>
</ul></li>
</ul>
<p>For example in the table above the team score for club A would be 625 <strong>not</strong> 640 as you would take the scores for Harry(190), Bert(150), Jim(150), and Simon(130). You could not take Fred's(145) score as that would give you only Gents.</p>
<p>My question is, can this be done easily as a series of Excel formula, or will I need to resort to using something more procedural?</p>
<p>Ideally the solution needs to be automatic in the team selections, I don't want to have to create separate hand crafted formula for each team. I also will not necessarily have a neatly ordered list of each clubs members. Although I could probably generate the list via an extra calculation sheet.</p>

57,947 | <p>I'm really confused by the various configuration options for .Net configuration of dll's, ASP.net websites etc in .Net v2 - especially when considering the impact of a config file at the UI / end-user end of the chain.</p>
<p>So, for example, some of the applications I work with use settings which we access with:</p>
<pre><code>string blah = AppLib.Properties.Settings.Default.TemplatePath;
</code></pre>
<p>Now, this option seems cool because the members are stongly typed, and I won't be able to type in a property name that doesn't exist in the Visual Studio 2005 IDE. We end up with lines like this in the App.Config of a command-line executable project:</p>
<pre><code><connectionStrings>
<add name="AppConnectionString" connectionString="XXXX" />
<add name="AppLib.Properties.Settings.AppConnectionString" connectionString="XXXX" />
</connectionStrings>
</code></pre>
<p>(If we don't have the second setting, someone releasing a debug dll to the live box could have built with the debug connection string embedded in it - eek)</p>
<p>We also have settings accessed like this:</p>
<pre><code>string blah = System.Configuration.ConfigurationManager.AppSettings["TemplatePath_PDF"];
</code></pre>
<p>Now, these seem cool because we can access the setting from the dll code, or the exe / aspx code, and all we need in the Web or App.config is:</p>
<pre><code><appSettings>
<add key="TemplatePath_PDF" value="xxx"/>
</appSettings>
</code></pre>
<p>However, the value of course may not be set in the config files, or the string name may be mistyped, and so we have a different set of problems.</p>
<p>So... if my understanding is correct, the former methods give strong typing but bad sharing of values between the dll and other projects. The latter provides better sharing, but weaker typing.</p>
<p>I feel like I must be missing something. For the moment, I'm not even concerned with the application being able to write-back values to the configuration files, encryption or anything like that. Also, I had decided that the best way to store any non-connection strings was in the DB... and then the very next thing that I have to do is store phone numbers to text people in case of DB connection issues, so they must be stored outside the DB!</p>

57,958 | <p>I like HtmlControls because there is no HTML magic going on... the asp source looks similar to what the client sees. </p>
<p>I can't argue with the utility of GridView, Repeater, CheckBoxLists, etc, so I use them when I need that functionality. </p>
<p>Also, it looks weird to have code that mixes and matches:</p>
<pre><code><asp:Button id='btnOK' runat='server' Text='OK' />
<input id='btnCancel' runat='server' type='button' value='Cancel' />
</code></pre>
<p>(The above case in the event you wanted to bind a server-side event listener to OK but Cancel just runs a javascript that hides the current div)</p>
<p>Is there some definitive style guide out there? Should HtmlControls just be avoided? </p>

57,987 | <p>Does anyone know how to write to an excel file (.xls) via OLEDB in C#? I'm doing the following:</p>
<pre><code> OleDbCommand dbCmd = new OleDbCommand("CREATE TABLE [test$] (...)", connection);
dbCmd.CommandTimeout = mTimeout;
results = dbCmd.ExecuteNonQuery();
</code></pre>
<p>But I get an OleDbException thrown with message:</p>
<blockquote>
<p>"Cannot modify the design of table
'test$'. It is in a read-only
database."</p>
</blockquote>
<p>My connection seems fine and I can select data fine but I can't seem to insert data into the excel file, does anyone know how I get read/write access to the excel file via OLEDB?</p>

57,990 | <p>After attending a recent Alt.NET group on IoC, I got to thinking about the tools available and how they might work. <code>StructureMap</code> in particular uses both attributes and bootstrapper concepts to map requests for <code>IThing</code> to <code>ConcreteThing</code>. Attributes automatically throw up flags for me that either reflection or IL injection is going on. Does anyone know exactly how this works (for <code>StructureMap</code> or other IoC tools) and what the associated overhead might be either at run-time or compile-time?</p>

58,000 | <p>We have a recurring problem at my company with build breaks in our Flex projects. The problem primarily occurs because the build that the developers do on their local machines is fundamentally different from the build that occurs on the build machine. The devs are building the projects using <code>FlexBuilder/eclipse</code> and the build machine is using the command line compilers. Inevitably, the <code>{projectname}-config.xml</code> and/or the batch file that runs the build get out of sync with the project files used by eclipse, so the the build succeeds on the dev's machine, but fails on the build machine.</p>
<p>We started down the path of writing a utility program to convert FlexBuilder's project files into a <code>{projectname}-config.xml</code> file, but it's a) undocumented and b) a horrible hack.</p>
<p>I've looked into the -dump-config switch to get the config files, but this has a couple of problems: 1) The generated config file has absolute paths which doesn't work in our environment (some developers use macs, some windows machines), and 2) only works right when run from the IDE, so can't be build into the build process.</p>
<p>Tomorrow, we are going to discuss a couple of options, neither of which I'm terribly fond of:</p>
<p><strong>a)</strong> Add a post check-in event to Subversion to remove these absolute references, or <br>
<strong>b)</strong> add a pre-build process that removes the absolute reference.</p>
<p>I can't believe that we are the first group of developers to run across this issue, but I can't find any good solutions on Google. How have other groups dealt with this problem?</p>

58,123 | <p>This is actually a two part question. First,does the HttpContext.Current correspond to the current System.UI.Page object?</p>
<p>And the second question, which is probably related to the first, is why can't I use the following to see if the current page implements an interface:</p>
<pre><code>private IWebBase FindWebBase()
{
if (HttpContext.Current as IWebBase != null)
{
return (IWebBase)HttpContext.Current.;
}
throw new NotImplementedException("Crawling for IWebBase not implemented yet");
}
</code></pre>
<p>The general context is that some controls need to know whether they are executing as a SharePoint webpart, or as part of an Asp.Net framework.</p>
<p>I have solved the problem by requiring the control to pass a reference to itself, and checking the Page property of the control, but I'm still curious why the above does not work.</p>
<p>The compiler error is:
Cannot convert System.Web.HttpContext to ...IWebBase via a reference conversion, boxing conversion, unboxing conversion, wrapping conversion or null type conversion.</p>

58,190 | <p>My current view is no, prefer Transact SQL stored procedures because they are a lighter weight and (possibly) higher performing option, while CLR procedures allow developers to get up to all sorts of mischief.</p>
<p>However recently I have needed to debug some very poorly written TSQL stored procs. As usual I found many of the problems due to the original developer developer having no real TSQL experience, they were ASP.NET / C# focused.</p>
<p>So, using CLR procedures would firstly provide a much more familiar toolset to this type of developer, and secondly, the debugging and testing facilities are more powerful (ie Visual Studio instead of SQL Management Studio). </p>
<p>I'd be very interested in hearing your experience as it's seems it is not a simple choice. </p>
