[RESOLVED] Convert Xliveless sample from C++ to C#

Hi,

Is it possible to convert the attached C++ code sample to C# code and if so how? The reason I am asking is because I had an idea for some code I recently made to be able to convert live saves for gta to liveless save games so I don't have to start the whole game again in the middle of a current game.

I have requested this thread moved to the C# section because I would have better luck converting the across languages rather than down a level.

Edit:

By the above I meant it would be easier converting the code to another modern language that uses possibly the same framework rather than trying to convert to an older language such as Visual Basic 6.0 which, uses a different framework.

Thanks,


Nightwalker

This is my attempt at using the C++ to C# Converter demo from Tangible Software Solutions.

C# Code:

public static class GlobalMembersSaveToGameFolder
{
    public static void getSavefilePath(int __unused, string pBuffer, string pszSaveName)
    {
        sbyte pszPath = (string)(0xF9FF08+dwLoadOffset);
        if (dwGameVersion == 0x00010001)
            pszPath = (string)(0xFA7778+dwLoadOffset); // char pszProgramPath[128];
            else if (dwGameVersion == 0x00010003)
            pszPath = (string)(0xFBF260+dwLoadOffset);
            else if (dwGameVersion == 0x00010004)
            pszPath = (string)(0xFC4700+dwLoadOffset); // ?? FC4500?
        pBuffer = pszPath;
        pBuffer += "savegames";
 
        // check path and create directory if necessary
        uint attrs = GetFileAttributes (pBuffer);
        if (attrs == INVALID_FILE_ATTRIBUTES)
            CreateDirectory (pBuffer, null);
        else if (!(attrs & FILE_ATTRIBUTE_DIRECTORY))
        {
            trace("ERROR: unable to create directory '%s', file '%s' already exists\n", pBuffer);
            pBuffer = pszSaveName;
            return;
        }
        if (pszSaveName != null)
        {
            pBuffer += "\\";
            pBuffer += pszSaveName;
        }
    }

    {
        switch (ul_reason_for_call)
        {
        case DLL_PROCESS_ATTACH:
            if (dwGameVersion == 0x00010001)
                injectFunction(0x608660, (uint)GlobalMembersSaveToGameFolder.getSavefilePath);
            else if (dwGameVersion == 0x00010002)
                injectFunction(0x6080E0, (uint)GlobalMembersSaveToGameFolder.getSavefilePath);
            else if (dwGameVersion == 0x00010003)
                injectFunction(0x60BAC0, (uint)GlobalMembersSaveToGameFolder.getSavefilePath);
            else if (dwGameVersion == 0x00010004)
                injectFunction(0x60BBD0, (uint)GlobalMembersSaveToGameFolder.getSavefilePath);
            break;
        case DLL_THREAD_ATTACH:
        case DLL_THREAD_DETACH:
        case DLL_PROCESS_DETACH:
            break;
        }
        return 1;
    }
}

xliveless.h:

}

extern "C"
{

Unfortunately, xlive.cpp is too big at 845 lines to convert with the demo version.

Here is the conversion of xlive.cpp I converted using the above method.
