Is there a better way to alter a form between 'StayOnTop' and 'Normal'. I ams setting the forms formstyle property to fsstayontop or fsnormal but I get an anoying flicker when I do this.... Anyone know of a way to toggle between states without flicker?

I just read in the Delphi help that it is inadvisable to alter formstyle at runtime. Many programs let you change between stayontop and normal at run time... Whats the best way?

Try using LockWindowUpdate(Form.Handle) before changing it and LockWindUpdate(0) after changing it.

I am not 100% sure if this will work but its worth a try...

Cheers,

Raymond.

I tried this one... this on win98 has the side effect of making all icons flash on the desktop, plus the form still flashes :(

Try using SetWindowPos with HWND_NOTOPMOST and HWND_TOPMOST...

Madshi, have you got an example of its use. I tried SetWindowPos(hwnd,HWND_TOPMOST,1,1,1,1,SWP_NOMOVE + SWP_NOSIZE) but it fails to compile... any ideas?

Madshi,
Well, I'm stupid.. as you can see I should have used handle instead of hwnd and it would have compiled.

Anyway.. it WORKS!  .. no flicker!
Answer the question... the points are yours.
Thanks Matshi for pointing me in this direction. :)
