This is a working sample:

Code: Select all  Expand view  RUN
#include "Fivewin.ch"


FUNCTION MAIN()

    LOCAL oDlg

    LOCAL hBmp

    DEFINE DIALOG oDlg

    hBmp = READBITMAP( 0, "C:\FWHARBOUR\BITMAPS\OPEN.BMP" )

    ACTIVATE DIALOG oDlg;
             ON PAINT PALBMPDRAW( hDC, 10, 10, hBmp, , , , , .T., oDlg:nClrPane )

    IF hBmp != 0; DELETEOBJECT( hBmp ); ENDIF

    RETURN NIL
