stripping a string from a TCHAR
I populate a TCHAR with a value from the registry:
TCHAR lpszDbPath[MSGBUFSIZ];
// registry key setup and error checking code omitted for clarity
RegQueryValueEx(hKey, _T("DBQ"), 0, &dwType, (BYTE *)lpszDbPath, &dwDataSize)) )
That gives me a value like the following in lpszDbPath
e:\MyDatabase\MyDB.mdb
what's the TChar way to strip the 'MyDB.mdb' from that result"?
thanks

RegQueryValueEx(hKey, _T("DBQ"), 0, &dwType, (BYTE *)lpszDbPath, &dwDataSize)) )
That gives me a value like the following in lpszDbPath
e:\MyDatabase\MyDB.mdb
what's the TChar way to strip the 'MyDB.mdb' from that result"?

You can use _tcsrchr, to do a reverse search for the back slash character, and set the result to zero.

This solution is only available to members.

If you don't want to include the back slash character in the stripping, set position one of the result to 0.
TCHAR * pos = _tcsrchr(lpszDbPath, '\\');
if (pos)
pos[1] = 0;
TCHAR * pos = _tcsrchr(lpszDbPath, '\\');
if (pos)
pos[1] = 0;

I'm not sure I understand how that works..
when lpszDbPath = "e:\MyDatabase\MyDB.mdb"
and I execute:
TCHAR * pos = _tcsrchr(lpszDbPath, '\\');
pos ends up equal to "\MyDB.mdb"
I want pos = "E:\MyDatabase\"
when lpszDbPath = "e:\MyDatabase\MyDB.mdb"
and I execute:
TCHAR * pos = _tcsrchr(lpszDbPath, '\\');
pos ends up equal to "\MyDB.mdb"
I want pos = "E:\MyDatabase\"

oh wait, sorry Axter.. duh.. I gotta loop it.. nevermind :)
