How do I get the directory where the executable is located?

I got the filename lik开发者_JAVA百科e this:

_TCHAR filename[_MAX_PATH];
GetModuleFileName(NULL,filename,sizeof(filename));

How do I remove the filename from this full path? Should I use regex?

You can use the Windows shell API function PathRemoveFileSpec to do this. Example usage is listed on the linked page.

Since you use VS++, you can use:

_splitpath and _wsplitpath functions to break apart path
