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.

I've had WAY too many people creating desktop shortcuts and leave off the "Start in Folder" field altogether.
 
If we find users moving the program, we let our tech-support team loose on them. (Those are NOT kind and gentle phone calls!!!)
 
Many of our customers don't allow their users have access to the registry either.
 
There are many methods for doing this, as well as many ways to corrupt it, but it's been working for us for about 7 years now!
 
Thanks for the comment though. It's always good to get another opinion.
