Getting file extension from path
-
This is hopefully a basic question but it's been a VERY long time since I used C++ and I just need to know how I can get a file extension from a path and compare to constant extension. I have an input: LPCWSTR pwszPath and a constant: WCHAR MY_EXT[4] = L".me"; I need to know if pwszPath ends with MY_EXT but I can't think how to do it.. Any help would be great!

Use
PathFindExtension. Matching extension will somewhat look like this...// Assumption: there is no '.' in extension
bool MatchExtension( LPCTSTR lpctszMyPath, LPCTSTR lpctszChkExt )
{
ASSERT( lpctszMyPath && lpctszChkExt );
LPCTSTR lpctszExt = PathFindExtension( lpctszMyPath );
// Or if you don't wish to link to shlwapi for this one function use
// LPCTSTR lpctszExt = _tcsrchr( lpctszMyPath, _T( '.' ));
return ( lpctszExt && _tcscmpi( lpctszExt + 1, lpctszChkExt ) == 0 );

What about PathFindExtension [^]? :)

I don't know (maybe bits of thougths? :-D). BTW apparently the same happens from Germany...;P (this thread is a bit dated)
