I can only select 13 files, if more than this number the GetPathName or GetNextPathName will return a string "||", what's wrong with this ?

look like 13 file-names overload the buffer or something.

Hi ahTri
This is because CFileDialog set the buffer which stores the file names(lpstrFile member of OPENFILENAME struct) to 260 chars.

To verify this call ::CommDlgExtendedError function and you will get the error : FNERR_BUFFERTOOSMALL

You can derive a class from CFileDialog and set the buffer size to what you want.

Download the sample application from this site:
http://support.microsoft.com/download/support/mslfiles/OfnKing.EXE 

The buffer size is defined by the member variable m_szBigBuffer in CustomFileDialog.h

Try it out.
