• Hexxagonal 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

• Need_Helpss VS 2005 compile problem with asserts

  I just started compiling my C code with VS 2005 (I was using VS 2003) and I ran across a compilation error that I've never seen with any other Microsoft , Intel or GNU (in multiple *nix platforms) compiler. The code calls macros from other macros and more importantly has an assert. When I compiled with -E, I see the following code generated: { if ( (int)((( (void)( (!!(0)) || (_wassert( [ "0", [ "d:\\mywork\\cmochk\\cmop ...Show All

  Hi everyone, I have just bought and installed Visual Studio 2005 Pro, and I have a problem with its OpenMP support. I have been using the Beta 2 before, and wrote code that uses OpenMP.

• COOPERMAN _CRT_SECURE_NO_DEPRECATE has no effect

  MSDN clearly states that if you define _CRT_SECURE_NO_DEPRECATE it "will disable deprecation warnings". I tried adding _CRT_SECURE_NO_DEPRECATE to the Preprocessor Definitions and #define _CRT_SECURE_NO_DEPRECATE to the code. In both cases I still get a C4996 warning from every single strcpy call. The only way to disable the warning, as far as I can tell, is to use #pragma warning (disable:4996) or add the warning to the C/C++ settings (Ad ...Show All
