Change color twice without see the change

Hi

I have a form.panel1.color = clsilver.
i want to print the panel and i have to change the color of the panel in clwhite.

 Form.Panel1.color:=clwhite
 Form.print;
 Form.Panel1.color:=clsilver

But i dont want to the person to see the change of color on the screen.
Is there any method or command to not change the color on screen?

Thanks

Use the LockWindowUpdate API call to lock the updateing etc...

LockWindowUpdate(Form1.Handle);

Check the help file out for futher usage etc...

I don't know how to do that exactly, but you can by doing a hide on the form, before the print event, (still having your change panel colour inbetween).

Then design a small form with borderstyle none, to display a message to the user, something like "PLEASE WAIT WHILE THE FORM IS PRINTING".

Change the colour of the panel back and close the second form after the print event and then show the first one ...

Another way, maybe is this :

Capture the bitmap of the form, do your color manipulations on this one and print the bitmap.

Zif.
