A function to retrieve the directory of a program

A small function to retrieve the directory a program is being executed from

Introduction

I've needed to get the directory a program was running several times. I've used it to determine where configuration files could be found. I've used it for determining where images should be stored/loaded. I've also had to write it from scratch several times Frown | :( . I'm submitting it here so hopefully someone else doesn't have to figure it out themselves.

I've found that using _getcwd isn't accurate whenever the user is allowed to use the file dialogs to open or save files. If they move to a different directory in the file dialogs, the current working directory is changed as well

CString GetProgramDir()
{
    CString RtnVal;
    char    FileName[MAX_PATH];
    GetModuleFileName(AfxGetInstanceHandle(), FileName, MAX_PATH);
    RtnVal = FileName;
    RtnVal = RtnVal.Left(RtnVal.ReverseFind('\\'));
    return RtnVal;
}

It's not much, but I've found it helpful and hope that someone else will as well.

The point was to get the directory of the program. This could be used to locate files. I frequently use this when using .ini files from the program directory.
