Hi thanks but i don't understand this ??


This is to get a valid path to your user-folders without hard-coding the whole path: "c:\\...\\yourFolder\\".

This function is not imported in WinFile_v600! So you have to add this line between the two #imports:

        int  GetEnvironmentVariableW (string lpName, string& lpBuffer, int nSize);

This function is not imported in WinFile_v600! So you have to add this line between: #import "kernel32.dll" ... #import:

        int  GetEnvironmentVariableW (string lpName, string& lpBuffer, int nSize);

I have added but what about thiis error ??

OpenNewFileForWriting' - function not defined

ok - xp may still be ANSI and not wide (CP_UTF8).

But GetEnvironmentVariableW will be more 'future-safe' especial if he will install Win 7 or 8 as xp is not supported anymore.

I myself won't like the idea reading/writing wide-char but the path-string is still ANSI?

Well ankityadav should try and print out the paths and use what ever works.

You already have all the answers you need in this post
The question is do you just want someone to write for you the entire code
