• dcallan ultra fast binary writes

  Hello, can anyone please help... This is a bit of a general question. My C knowledge is limited to the K&R book. I have used the fsutil tool on windows xp and noticed that the command: fsutil file createnew c:\$delthis.bin  1234567890  which creates a file over a gigabyte in size is extremely fast - it takes about a second on a PIII 800MHz with 256MB memory. This seems to be amazing given that it zeros the whole file, rat ...Show All

• Will Riley CDialog::DoModal asserting in CWnd::DestroyWindow

  To Brian and Martin, who were involved in helping me out with this , please don't shout at me... This thread does follow on from that post - and I'm now investigating refactoring a static library which contains a few MFC classes into a shared DLL - using __declspec(dllexport) to export functions and classes that will be needed across all facets of the solution that need the shared functionality. I've looked all over the place for an ans ...Show All

• Bobby Thurman Thread Termination

  Is there any way to easily instruct windows to wait for a given thread to complete upon exit of the process in which it was created, other than explicitly calling a function such as WaitForSingleObject at the end of execution As an example, if I create a thread in order to run an asynchronous function, such as one which performs a large calculation and stores the result to a file, logically it should continue to execute until it is finished even ...Show All

• Rod_Kane Option to supress warnings in standard headers?

  If I'm compiling a program that uses some standard C++ headers, I get all sorts of horrible warnings.  For example, compiling the following program with cl.exe: #include <iostream> #include <list> #include <string> int main() {  return 0; } Generates the following output: cl test.cpp test.cpp C:\VC++2003\include\ostream(574) : warning C4530: C++ exception handler used, but unwind semantics are not enabled.

• Mike Royle vc++8.0 bug: access violation upon call of any CImageList methods

  I have sucessfully imported and compiled a complex MFC 6.0 project from vc++6.0  into vc++ 8.0 (MFC 8.0). It contains several subprojects (libs and dlls). In vc++ 6.0 those project linked MFC6.0 statically and after I imported it to vc++ 8.0 I set the linkage of MFC8.0 to "shared". However when I try to compile and link the project in vc++ 8.0 in release mode (debugmode works fine) I get an acess violation in afxcomctl32.inl. This happnes w ...Show All

• Daan van Schaijk Program runs slower when compiled with Visual Studio 2005 (in Release with optimization)

  Hey, I have a performance problem with the new Visual Studio 2005. My code (which is a genetic algorithm) is 3 times slower when compiled under Visual Studio 2005 compared to when I was compiling it under Visual Studio 2003. With Visual Studio 2003, it used to run in 3.0639 seconds, and now it runs in 9.0031 seconds. I run both code in Release. I tried every optimization option, and adding the /D_SECURE_SCL=0 compiler command to the project opti ...Show All

• Umamageswari LNK2028 when using /clr:oldSyntax in VS2005

  It appears that the error relates to using /clr:pure, but I am not.  The class it is complaining about is in the unmanaged library, and that library is specified in the link options.  It was migrated to and built by VC++ 2005 from the 2003 version. I don't understand the extern "C" part of the error msg because there is nothing in this class that references any C code - it is all C++.  There is a C code module in the library, but ...Show All
