If individual pixels are what you want to examine, look up the .Point method in your help. If it's whole blocks of pixels you want to deal with, look up the .PaintPicture method in the same place. If you're using earlier than VB4 then you *might* need to use the BitBlt API from a DLL. -- Paul Sampson____Principal Consultant Onyx Systems______Onyx Internet Zetland Buildings__Exchange Square__Middlesbrough__TS1 1DE__UK 33711 \\/+ Vox(+44)1642-216200 Fax(+44)1642-216201 mailto:paul.sampson@onyx.net +ooo BB 74 A4 EF 03 F8 44 C1 F3 75 FE C6 7E F9 6E 43 http://www.onyx.net >--<
