• Why does my count(*) query time out but the inline view whose records it is counting does not?

  - by RenderIn

  Can't figure this one out... when I execute a select query it shows an explain plan cost of ~4500 and takes ~3 seconds to return. When I wrap that query (no changes) inside of: select count(*) from ( /*query here*/ ) It times out. It's at 5 minutes and counting now. I tried this in SQL Developer and Aqua Data Studio -- same results.

• Does anyone know a light Vim scheme which makes coding more readable and pleasant?

  - by janoChen

  I know a lot of nice dark schemes for Vim which makes coding more readable and pleasant such as ir_black, wombat, zenburn. Its weird but I haven't seen so many popular light themes (white background). Does anyone knows a light Vim scheme which makes code more readable and pleasant to see? (that makes code less confusing to distinguish, something like Visual studio's default scheme?)

  I have a developer that is having trouble connecting to a SQL Server instance by entering the server name (local)\HIS_SERVER_INSTANCE into Visual Studio-Server Explorer.

• How to enable nullptr from C++0x in the Visual C++ 2010?

  - by Sorin Sbarnea

  I wonder how can I enable the nullptr in the just released Visual Studio 2010. (C++ project, not managed). This is one of the new features but it is not available by default and looking inside the documentation at http://msdn.microsoft.com/en-us/library/4ex65770(VS.100).aspx it seams that it is enabled by /clr but this is managed! Is this a feature added only for .NET?

  The MFC program I am debugging is printing this message in the "Output" window in Visual Studio 9.0: HEAP[AppName.exe]: Invalid allocation size - 99999998 (exceeded 7ffdefff) I'm pretty sure this is due to a bad "new", uninitialized variable or similar error. The question is: how do I get the debugger to stop on this message so that I can view the stack trace and solve the problem?

• WP7 PanoramaItem with Icon/Button next to Header

  - by Ramon Bosch

  Windows Phone 7's People hub has an "all" panorama item with "search" and a "new" buttons right next to the header/title. I can't seem to accomplish this with PanoramaItem in Visual Studio using the standard Panorama control. I don't know enough Silverlight/WPF either to be able to position something manually and control transitions/movement correctly. How can I set a button (or any object, for that matter) to go alongside the header of a wp7 PanoramaItem? Thanks!

• Does a simple delphi form app needs any libraries or dependencies to deploy?

  - by peterg

  I need to code a simple form application and I want to make it easy to deploy (without installing libraries or dependencies), I don't want to use visual studio cpp or csharp because clr apps compile with .net frameworks and I have no much experience with mfc and dialogs. So I was wondering which libraries does a simple delphi vcl forms app (those using TForm) use, because I've never had to install anything to run simple delphi apps.
