本文提供了一种简单的方法来获取程序的运行目录。该方法对于确定配置文件的位置、图像的存储和加载路径等非常有用。通过使用GetModuleFileName函数并进行适当的字符串处理，可以确保即使在用户更改文件对话框中的目录时也能准确地获取程序所在目录。

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 :( . 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.
