Ahh.. I think you got it wrong. There are two flags as the parameters. Take look at this:

Declare String CD_GetFile in HTWindow ;
   String cStartDir, String cStrFilter, Long hWndParent, ;
   Long nPosition, Long nX, Long nY, ;
   Long uFlags, Long uFlagsEx, ;
   String cWndTitle, String cBtnCaption

The "uFlags" is the standard GetOpenFileName() API flags. While the "uFlagsEx" is the extended one. Use the "uFlagsEx" and pass in HTCDF_NOSELECTDIR in order to prevent the folder selection. If you don't use HTCDF_NOSELECTDIR in the "uFlagsEx" parameter then it behaves as a standard GetOpenFileName with whatever "uFlags" you passed in.

Still confused about it ?
