• Why are structs not allowed in template definitions?

  - by nils

  The following code yields an error error: ‘struct Foo’ is not a valid type for a template constant parameter: template <struct Foo> struct Bar { }; Why is that so? template <class Foo> struct Bar { }; works perfectly fine and even accepts an struct as argument.

• Refreshing Visual Studio's COM references tab

  - by r_honey

  I right-clicked on the bin folder of my web app to add a COM Reference. I did not find the desired Com reference in the list. I went back to the Command Line to register by desired Com dll using resvr32. However, the COM references tab does not shows it (looks like the information is cached somewhere). Even restarting VS did not help. Is their any easy way to refresh the COM references tab without rebooting the machine itself??

• Are UML semantic variances necessary?

  - by Gabriel Šcerbák

  I am asking if it is necessary or useful to have semantic variances in UML. Would it not be more useful when it was more formal and therefore verifiable or even used for rapid prototyping. What is the benefit of the variance? Can you give some examples?

• Scaffolding Extensions: NoMethodError

  - by marienbad

  Not sure if many people are familiar with Scaffolding Extensions for Ruby, but I've looked through their docs, forums, and even the source code of the Heroku test site, and not found an answer. I made a basic Sinatra app and followed right from the RDoc's instructions: require 'scaffolding_extensions' require 'sinatra/base' class Thingy < Sinatra::Base scaffold_all_models end gives undefined method 'scaffold_all_models' for Thingy:Class (NoMethodError) and I know Scaffolding Extensions is loadable because I can successfully set some config variables in its classes.

• How can I extract the original image stream from a System.Drawing.Bitmap object?

  - by skolima

  I am embedding images into my assembly using .resx files. Upon runtime, I need to save the images into standalone files, restoring the original content. How can I extract the original file stream from an System.Drawing.Bitmap instance? I know I can create a stream using Bitmap.Save(), but this transcodes (and in effect - inflates) the images, even when saving a PNG back as PNG. Or perhaps my mistake is reading them from Resource as Bitmap in the first place?

• iphone dev - activity indicator scroll with the table

  - by Brian

  In a view of my app I subclass tableViewController and has an activity indicator shown up when the table content is loading. I put it in the center of the screen but it scroll with the tableView (I guess the reason is I add it as a subview of the table view). Is there a way that I can keep the activity indicator in the center of the screen even the table is scrolling? Thanks in advanced.

• How do you unit test a class that's meant to talk to data?

  - by Arda Xi

  I have a few repository classes that are meant to talk to different kinds of data, deriving from an IRepository interface laid out like so: In implementations, the code talks to a data source, be this a directory of XML files or a database or even just a cache. Is it possible to reliably unit test any of these implementations? I don't see a mock implementation working, because then I'm only testing the mock code and not the actual code.

• generic programming in C with void pointer.

  - by Nyan

  Hi everyone, even though it is possible to write generic code in C using void pointer(generic pointer), I find that it is quite difficult to debug the code since void pointer can take any pointer type without warning from compiler. (e.g function foo() take void pointer which is supposed to be pointer to struct, but compiler won't complain if char array is passed.) What kind of approach/strategy do you all use when using void pointer in C?

• Tuning SQL Server 2008 for web applications

  - by Kibbee

  In one of the Stackoverflow podcasts, I remember Jeff Atwood saying that there was a configuration option in SQL Server 2008 which cuts down on locking, and was kind of an alternative to using "with (nolock)" in all your queries. Does anybody know how to enable the feature he was talking about, possibly even Jeff himself. I'm looking at deploying SQL Server 2008, and want to see if using a feature like this would help out my web application.

• Facebook Thumbnails Issue Traced to safe_image.php

  - by talkinggoat

  For some reason, facebook's safe_image.php script isn't generating thumbnails, properly. It's generating a 1x1 image... even though the correct image is linked in the script's parameters. Example: <img class="img" alt="" src="https://s-external.ak.fbcdn.net /safe_image.php?d=AQBtrCt_Es_KsED0&w=90&h=90&url=http%3A%2F %2Fwww.southlapatriots.info%2Fimages%2FScamra%2FJayCastilleCouncil2.jpg" The linked image is correct, but it is still only generating a 1x1 image.

• Customising the .NET PrintPreviewDialog?

  - by Gary Willoughby

  Currently i'm using the PrintPreviewDialog to open a window to preview the printed pages before they are sent to a printer. The problem is though that it first appears very small, at the top left of the screen and the buttons are too small. Is there anyway i can set a starting size for this dialog or start position or even make the little buttons a little bigger? Or do i need to implement my own?

• Step by step help and guidance

  - by ChrisC

  Is there such a thing as a paid (or free would be GREAT, but unlikely I'm thinking) resource that could help a newbie with guidance and help as I create my first app (C# with SQLite db)? Stackoverflow is great, but a one-on-one person who was familiar with exactly what I'm doing would be even better.

• Receiving a NullPointerException when calling a cursor in Android

  - by LordSnoutimus

  I am creating an application which tracks the users location using GPS, stores the longitude and latitude in a database using a content provider then output the first long and lat to a mapview. I am able to create the cursor using this line of code: Cursor c = getContentResolver().query(GPSContentProvider.CONTENT_URI, null, null, null, null); startManagingCursor(c); However, when I make a call to move to the first row in the database or even try to close the cursor using c.close(); I receive a NullPointerException.

• visual studio recognizing .asp properly or suggestion for classic asp editor/iDE

  - by Neil Warner

  How do I get visual studio 2005 to work best with .asp files? I used to have this on my old PC but I can't get the settings right. I exported and important all my old settings and still no dice. alternatively I think there might be an even better choice for classic asp IDE editor. It'd be nice to have intellisense, completion, highlighting, stuff like that for ASP (vbscript) and css/html at the same time. (I'm happy not to type out css selectors) thanks

• Can information encoded with a one time pad be distinguished from random noise?

  - by Robert

  I understand that the cyphertext from a properly used one time pad cypher reveals absolutely no data about the encrypted message. Does this mean that there is no way to distinguish a message encrypted with a one time pad from completely random noise? Or is there some theoretical way to determine that there is a message, even though you can't learn anything about it?

• When does post-update get called (GIT)

  - by Michael

  My git setup was working beautifully, then stopped cooperating today. Right now, I can git-pull, git commit just fine from my local machine. When I git push, the push goes through, but the server files don't actually get updated. Now I wonder, is my post-update file even getting called anymore? I've checked the permissions, and they are all group +x, and I'm a part of the group... any other suggestions?
