• TallMike mkDir

  Is there a way to use _tmkdir to create an entire directory given a path For example, if I give C:\AA\BB\CC , then assuming AA, BB and CC do not exist, the function should create all of them. Thanks, KarthikR In this case as Nishant suggested, SHCreateDirectoryEx should do the job. I have unmarked my post since Nishant's one is more directed into the problem. Thanks, Ayman Shoukry VC++ Team From the help at http: ...Show All

• rex letor My Visual Studio does not load stdafx.h & stdafx.cpp in my project file

  Whenever I create project file it won't work because stdafx.h and stdafx.cpp files are not preloaded into the project file, how do I fix this problem You can set the use of precompiled headers in your project properties.  You can make it automatic, not happen at all, or happen only on files which have the #incude set ( so only some files use precompiled headers ). Yeah, I would agree, if for some reason you wanted to extend an ...Show All

• Saranga Amarasinghe Improper assembly code generation for inlined method on Release|x64 for AMD64 on Visual Studio 2005

  The complete source code and .vcproj file are posted below. When the cometLocationType operator= is declared in the following manner: inline cometLocationType& operator=(const cometLocationType& point) When the value of ret1, is printed inside the main function, the value of mX and mY are both 0 when they should be 260. This is because inside the operator=, it falsely thinks that "this" and "&point" are equa ...Show All

• Raichur C# array equivalent in C++/CLI

  Hi, I'm writing a C++/CLI wrapper for legacy C++ code such that it can be used from e.g. C#. The latter has built-in support for arrays, which even can be jagged. In order for my C++/CLI wrapper to accept these C# arrays (e.g. as member function parameter), I use the abstract System.Array class from which the C# arrays inherit. Is this "the" approach, or are there better approaches P.S. While the MSIL code generated by the C# ...Show All

• Duece Tips for speeding up debugging (stepping through code)?

  I've got one particular large C++ project that, in VC 2005, when stepping through code in the debugger, it takes approximately 2 seconds for each hit of the F10 key (i.e. each line of code) to be executed. I've tried many things to attempt to speed it up: disable intellisense, renaming feacp.dll, removing all additional output windows, watch, breakpoints, etc, removing navigation bar from text editor window, disabling anti-virus on the machine ...Show All
