Resolved Moving a picture: unwanted white spot

[DaSchmarotzer]

Hello,

I am new to vb.net (and it is my first programming language) so I learn by reading, messing around and creating random programs. I just created a small two-players game but I have a problem: when I move a picture box using the arrow keys, there is a white square that appears for a few split seconds, making the game look unprofessional. I'm not saying that the graphics are good or that I'm a pro though.

Here is a 2 seconds clip to show you what I mean.

Any help would be appreciated! Keep in mind that I am not an expert though. Thanks!

The first option would be to set the DoubleBuffered property of the form to True.

Well, that was easy. Almost disappointing. Thanks a lot!

What the DoubleBuffered property does is cause any changes to the form to be drawn to a bitmap in the background first and then that bitmap to be drawn to the form. This ensures that any changes that result in a series of visual changes are all implemented as a single unit, thus helping to prevent flicker and other artefacts like what you experienced.
