Hi, I want to be able to make my ICON flash to attract the users attention, something like the way the RECORDER program flashs its icon. Does anyone have any ideas. I have posted this question twice already and have not recieved any replies, I'm sure someone out there knows the answer. -- Rakesh Kumar Tandon : email - rkt@bj.co.uk Boldon James Limited : phone - 0260 280465 Damian House, West Street : fax - 0260 298030 CONGLETON, Cheshire :

Ok, this is all theory and I haven't tried programming this but this is what I think the recorder app is doing when it is flashing its icon. Firstly lets look at what spy tells us: 0000 WM_TIMER 00DF 0A9DOOC2 erase sequence 5078 WM_ICONERASEBKGND 0846 00000000 0000 WM_TIMER 00DF 0A9DOOC2 paint sequence 5078 WM_PAINTICON 0001 00000000 5078 WM_ICONERASEBKGND 0836 00000000 50BC WM_NCPAINT 0001 00000000 Where: 5078 is the parent (main) window 50BC is the list box within the main window From this we can deduce that recorder sets up a simple timer (ie no timer callback function) and on receipt of alternate WM_TIMER sends messages to itself which then erase and paint the icon. I would guess that recorder isn't doing anything fancy with these messages, just passing them to DefWindowProc. However, to erase the icon I think you need to InvalidateRect the icon window (Main window of the app). Painting the icon you just pass the message on similarly with the second WM_ICONERASEBKGND, which I guess fills in the background around the icon. I think the NCPAINT message can be ignored. It seems to be going to the list box, why I can't think! Hope this is useful, anyone have any other ideas??

Does anyone Try not setting up any icon -- that way, you'll get messages that let you paint yourself when iconized. Then set a timer and paint what you choose (including, for instance, an icon). Look at the source for clock. -- Barry Press Internet: press@venice.sedd.trw.com

Big drum-roll, "dadadadadadadada..." <Clash> Call FlashWindow. Do you have an SDK? Ken Sykes Disclaimer: The above opinions are solely my own.

To find out how to flash an icon, look up the function FlashWindow() in your SDK manual. Use FlashWindow and a timer to flash your window (iconized or normal) multiple times. -- Christine Roine Cognos Incorporated S-mail: P.O.
