In the C++ project I changed it to output a dll. I changed it to use the /clr flag. I changed it to use Multi-threaded Debug DLL (/MDd) because...
Challenging Runtime Error when calling Native Code from Managed Code
First_Layer I have a win32 dll written in VC++6 service pack 6. Let's call this dll as FirstLayer. I do not have access to FirstLayer's source code but I need to call it from managed code.

I can build and run the program on my C drive, and others can run it from their C drives, and everything works. But in some situations both my DLL and the Sybase DLL are located on the F drive instead of the C drive. In those cases my DLL app...

In Visual Studio 2008, how/why are extra (non-specified) .LIB files be added to the linking stage?
I discovered yesterday that one of our projects is linking in a few libraries that aren't specified in the project. I've double-checked (by manually reading the .VCPROJ file) that the .LIBs in question aren't specified. They aren't mentioned anywhere in the file, let alone in its 'libraries' section. And yet, when I look at the 'Comma...
Why can't a "procedure entry point could not be located in dll" when I definitely put it in?
I have a really vague problem, but I hope someone can help with it. I was modifying a C++ project and yesterday it was still working, but today it's not. I'm pretty sure I didn't change anything, but to be completely sure I checked the project out from SVN again and I even reverted to a previous system restore point (because this is a wo...

Combine native DLL and assembly into a single DLL
I am currently programming in C++ and C#. Using native C++ for the numerical computing part. Originally I intended to use C++/CLI to make a wrapper to the native C++ classes, but I found it would result in a 2 to 4 times slowdown. So I decided to compile my native C++ to a DLL and call in .NET/C# via P/Invoke. I will do data preproces...
