• rmtuckerphx App hogs CPU when mouse pointer moved over it

  My MFC app hogs CPU when the mouse pointer is moved around over it. I'm using task manager to monitor the CPU usage. No othe app seems to do this. If my app has a modal dialog box up then it doesn't happen. The app is built with Visual Studio 2005. My main window is only handling WM_CLOSE, WM_ERASEBKGND, WM_SIZE and WM_SYSCOMMAND (none of which get fired when you just move the mouse pointer around over it). If you get furious with the mouse p ...Show All

  Note: This post was originally posted here, but someone moved it to the CLR forum.

• ThE_lOtUs very dissappointed with visual c++ 2005

  I was astonished on how c++ gained so much added bulk... PLZ... VC++ 2005 is anything but iso C++ compatible... "99.9% iso c++ compatible"... it has like 30 extra keywords that shouldn't be there in the first place...  Looks like I will have to go with either c# or start getting to be friends with an old pal called GCC. This is just a feature request.   TOMDX wrote:   TOMD ...Show All

• ronmac Where is C99 round function?

  First, I post this question to Visual C++ Language but it seems it's OT there, so I repost it here as it relates to VC++ 8.0 libraries Hi, It may seem to be extremely trivial quesion, but I completely have no idea why I can not find round function in math.h I use VC++ 8.0 so I suppose it brings very up to date C/C++ librareries. round function was added in C99: http://www.dinkumware.com/manuals/reader.aspx b=c/&h=math.html#roun ...Show All

• Coyote13 C/C++

  Hello everyone, I'm an "old timer", because I started learning computer languages in 1974 (!) on a VAX system. (Basic, Fortran IV, Fortran 77, Pascal, Assembler, Cobol, C, C++, ...) My preferences are for C++ (still do) programing, but because of my professional duties, I stopped programing since 1988. Now I'm "semi-retired" and would like to restart using C/C++ but... What should I decide to buy, I mean, what kind of language to start with Vis ...Show All

• Agalab August CTP

  I arrived late to this party starting with the July Professional CTP from MSDN 4 weeks ago. In that time I've found and reported 3 significant bugs. I've been waiting for the August CTP to kick its wheels but now I find that it's by "invitation" only. Given that I'm actively participating in this beta trial - how do I get an "invitation". Alan Thanks, but I need the Professional version. ...Show All

• !Carlo! How to make crtdbg.h and new(std::nothrow) work

  Hi. I've been using the crtdbg functions for a while to find memory leaks, and it works great when I use the following preprocessor statements. #ifdef _DEBUG #define _CRTDBG_MAP_ALLOC #include <crtdbg.h> #define DEBUG_NEW new(_NORMAL_BLOCK, __FILE__, __LINE__ ) #define new DEBUG_NEW #endif As you'll know, this way the crtdbg functions show the correct file and line where the memory of the leak was reserved, using the "new" operat ...Show All
