Question Double buffering

[BlackByte]

Hi, does anyone the best way to prevent flashes on a form. I have tried setting Doublebuffered to True in the properties, i have tried using the Me.SetStyle() methods, still no change. A link in the right direction will also do.

Normally DoubleBuffering should do the trick. What kind of Form do you have, and how often does it get refreshed?

WindowState is set to Maximized, the flashes occur when the form is loaded, there is only 1 form. The font size of the labels is set to 16, it is labels that delay painting.

Do you have an image for the form background? These tend to do what you are describing.

 

[BlackByte]

Yes i do, would you advise me to remove it, or is there another way to get around it?

 

[newguy]

If you want to remove the background image select none in the designer. I used to have an API for this but can't seem to find it (weird) - it would stop it from redrawing, but could redraw it when needed. The flickering is from all the redrawing of the form when an image is the background.

Ok thanks, bt i'm afraid the application won't be as good looking without the Background Image.

I know this is off subject, but I learned about double-buffering for punch cards, mag tape, and early disk systems, back in 1964. Thanks for the short trip down memory lane.
