• smith_kbase Rebuild using shared precompiled headers doesn't work

  To combat a long build time, I consolidated common headers across 20+ projects into a single precompiled header, to be shared.  The pch file is generated from a separate project (pch.vcproj with stdafx.cpp/h), and it works with clean builds and incremental builds (from editing one of the files belonging to the 20+ projects), but I get compile errors when I choose Rebuild.  Before presuming a bug, I'd like to ask the forum for he ...Show All

• Sheepe C++/CLI code porting problem

  I'm trying to port a C++.NET (managed extensions) application to C++/CLI. However I'm not very strong with the syntax yet. What I'm trying to do is to create a wrapper for a C Dll file. To do this I'm using DllImport but I failed to found documentation on it's use. There are some problems due to changes of the syntax but I couldn't find out why yet. The C++.NET line looks like this:   [DllImport("my.dll", CharSet = Ansi,  CallingConven ...Show All

• Janaka Best practice: P/Invoke or C++/CLI?

  If I need to access unmanaged code (Win32 dll or a 3rd party dll), I routinely find myself creating a C++/CLI class library project type (dll) and creating a few wrapper classes (and usually refactoring for simpler interfaces than the original function being called). After it's built, it's a .NET assembly that I can access from C# or whatever. I find it easier to do than using P/Invoke directly from C# (although creating a DllImportAttribute i ...Show All

• Gemini II Designer problem

• John Cramer MFC displays XP visual style only when VS2005 installed

  HI. I'm writing an MFC app and trying to use visual styles. I added the manifest file with the various lines, including: [...] name = " Microsoft.Windows.Common-Controls " version = " 6.0.0.0 " [...] My problem is that although this caused the application to render correctly in testing (e.g.: white menus), when I run the application on a machine that has XP, but not VS2005, it renders in the old style (e.g: grey menus). Anyone know wh ...Show All

• noeldp Function decorated names in DLL lib

  I've created  a DLL and want the debug build to produce a dll and lib with different name, something like MyLibd.dll and MyLibd.lib (as opposed to MyLib.dll and MyLib.lib). When I built the debug version of the EXE that uses the DLL in question I obviously linked against the debug version (MyLibd.lib), but noticed that the EXE still loads the release DLL (MyLib.dll). Looking at the debug lib I noticed that all decorated names refer to the r ...Show All

• js40 Bufferoverflowu.lib for amd64 is missing in whidbey beta 2

  Lets say you compile some code with the latest PSDK for AMD64 cpu. Then you compile your files into a library and expect users to use that library. However because of the security code there is a dependency for using bufferoverflowu.lib on the PSDK since it uses old CRT code. If you use #pragma comment(lib, "bufferoverflowu.lib") then the file must exist to be able to succesfully link. This is a problem if you compile your code with the PSDK an ...Show All

• ladydee File open mode ios::ate is not working correctly with standard c++ library

  In VC++ 6.0 the following sample program is not working as intended. It opens existing file and overwrites the contents. It should append at end of file because the mode ios::ate stands for: "ios::ate Opens an existing file (either input or output) and seeks the end. " It is working correctly if I use "fstream.h" in place of "fstream" or ios::app in place of ios::ate. Can any one tell me if it is known issue or do ...Show All
