  1. Re: Breaking up large class into manageable source files

    C++/CLI form designer places all code to h-file, and creates .cpp file with a single line #include "Form1.h" This is because it works by the same algorithm as C# and VB .NET designer. You can move...

    Re: Opinions on my get/set approach

    Unreadable and undebuggable. Just use plain C++ code for every property. Don't forget that get functions are usually defined as const.

    Re: unfamiliar function declaration

    Yes, these two declarations are the same, and in this context there is no need to use the first one (though the code is correct). auto return type with -> return-type syntax is used in templates. ...

    Re: Fill Array with even numbers only

    You can add internal loop and call rand until it generates desired number - odd or even.

    Probably you can explain this better, I don't think somebody can understand your question.

    OK, you can replace IncBuffer.insert with the code from my first post. Is there some problem with this?
  8. Re: Erorr asigning pointer to iterator ( only after porting to VS2013 )

    So, you need to add some buffer (char*) to vector. I don't see any reason to use vector iterator for reading plain char array. Please show some more code to get an advice how to rewrite it. For...

    Re: Unable to pass arguments to DLL function

    This is not mangling, it just causes GetProcAddress to fail. Maybe calling convention. Anyway, instead of these explanations, please post your code.
  11. Re: How to determine cross platform type during file save?

    Maybe you can detect whether lpszPathName is a network path, and then ask user to select line-end type. If file name is local, save with Windows line-ends.

    Re: Incorrect result in Bitwise operations

    What is initial data[j] value?
    Can you reduce this sample to single line of code, with hard-coded j value, which is supposed to give some result, but gives something else?

    Re: Unlcoking a mutex from crashed thread

    It is still not clear what do you mean by "crashed thread". Can you be more specific? Usually, when any thread in the process crashes, the whole process it terminated.

    Re: Unlcoking a mutex from crashed thread

    It is not clear wht do you mean here: task got crashed. If exception is unhandled, the whole program crashes. If exception is caught, here is the place to release the mutex.
  16. Re: How to convert a C# module into an unmanaged C++ dll?

    Automatic conversion doesn't exist. If your target platform is Windows, you can add .NET support to existing VC++ project. This converts the project to C++/CLI. Then add reference to C# library and...
  17. Thread: cpu ID

    Re: cpu ID

    Thread doesn't run always on the same core. When thread resumes its execution, it may be executed on any available core.
  18. Re: What technologies to use for modern Windows client development?

    According to your program description, I don't see any reason to use C++ at all. If you don't need to write cross-platform code, C# + WPF is the best choice. Additionally, C# is much better for...

    You have different Character set (Multi-byte - Unicode) in Debug and Release configurations.
  22. Re: Calling a DLL written in VC++.NET Native Code from a VB.NET project

    DllImport is correct way to call native function from VB .NET. Better to avoid full path: "C:\_MOPEKS\ ..." and leave only Dll name. Place Dll to .exe directory, current directory or make it...

    Re: Moving from VC++ 6.0 to VC++.NET

    Re: Moving from VC++ 6.0 to VC++.NET

    2. Yes, in native C++, but not in x64 build. You can, however, compile Assembly modules and link them with C++ modules. As mentioned before, it is much better to write this stuff in C++.
