OPENFILENAME lpstrFilter

What is the correct syntax for the lpstrFilter display strings and filter patterns when using multiple display strings and multiple filter patterns.
example:
CString str = "PS Font files (*.pfm;*.pfb)| Windows Font files (*.fon;*.ttf)|All files (*.*)||;

For OPENFILENAME, the string must be terminated by '\0's and not '|'. Using '|' is a CFileDialog only thing (it converts all the '|'s to '\0');
So a filter would be "Text Files\0*.txt\0All Files\0*.*\0\0"

Thanks!
