How to get Current Directory?

Asked 2009-05-17T19:05:38.123

I want to create a file in the current directory (where the executable is running).

My code:

LPTSTR NPath = NULL;
DWORD a = GetCurrentDirectory(MAX_PATH,NPath);
HANDLE hNewFile = CreateFile(NPath,GENERIC_WRITE,0,NULL,CREATE_ALWAYS,FILE_ATTRIBUTE_NORMAL,NULL);

I get exception at GetCurrentDirectory().

Why am I getting an exception?

GetCurrentDirectory does not allocate space for the result, it's up to you to do that.

TCHAR NPath[MAX_PATH];
GetCurrentDirectory(MAX_PATH, NPath);

Also, take a look at Boost.Filesystem library if you want to do this the C++ way.

To find the directory where your executable is, you can use:

TCHAR szFilePath[_MAX_PATH];
::GetModuleFileName(NULL, szFilePath, _MAX_PATH);
