Hi,

I solved my problem on the c++ side this way:

string strFilename = saveInternally(); char* cFilename = new char[strfilename.length()]; strcpy(cFilename, strFilename.c_str()); return cFilename; ...

I don't really understand, why i have to do an extra strcpy(..) in this case of returning the string value and in other cases, when i use the string internally i dont have to.. Can anyone please explain this behaviour to me?

regards Jann
