• Visual C# Do application settings work across cultures?

  I’m using the Application Settings (via the project properties for a C# assembly) in order to store default values for the application, but I’m finding that the auto-generated code doesn’t work across different regional settings. For example, if I use it store a float value called “Increment” with a value of 0.5 when set to an English culture, then the following code is generated: [global::System.Configuration.UserScopedSettingAttr ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. 2d GUI questions

  Hey all, Big post here, I'm in the process of creating a 2d gui in managed directx with c#, and I've run into some serious performance issues after a rather minimal interface with a few high res textures. Along the way I've wondered if I'm doing things right. I've also been really curious as to how a program like Picasa2 can do all of its rendering at lightning speeds, with pretty much zero load time no matter how big the images get, while it's ...Show All

• SQL Server Custom Front-End Using Multi-Value Parameters on Reports

  Hello, We have developed our own ASP.NET 2.0 (C#) front-end for Reporting Services (SQL Server 2005). The front-end is kind of "generic" in the sense that it looks at all the parameters for any report selected by the end-user and creates a display for the end-user to configure the parameter values. This all works fine, except for one report that has a multi-value parameter. On the report viewer through Report Manager, this multi-val ...Show All

• Visual C++ VC2005 %50 Slower then VC2003

  I just migrated a graphics application from VC2003 to VC2005.  After building it, I ran a small benchmark & found that VC2005 code was about %50 slower. The Application does a great deal of floating point and integer calculations.  It also converts doubles to int quite a bit (the VC2003 version used SSE to handle this). The VC2003 version used /G7 and /Ow (which are not available in VC2005) Compiler Switches Used: (vc2003)/arch ...Show All
