If you use the Windows API call LockWindowUpdate, you can pass the hWnd of the Picture Box and Windows will not update that area of the screen. &nbsp;<br />
<br />
Once you've finished drawing your objects on the picture box, call LockWindowUpdate, but with a 0 (zero) in place of the control handle, and the picture box will be redrawn with all your changes.

Can you post the code here so we can take a look?

 &nbsp;Ooops... ! During cutting and pasting to post the code here I noticed that I had a PictureBox1.Cls command outside the LockWindowUpdate. Moving it between the LockWindowUpdate PictureBox1.hWnd and LockWindowUpdate 0 made the flickering dissapear....<br />
<br />
Thanks!

I have a PictureBox wich I draw different objects in, using the Line, PSet and Circle method. I move these objects around by clearing the entire PictureBox and redrawing them in a different position. The PictureBox also contains a background (Gridlines) which are not moved. &nbsp;The problem is that this method makes the objects flicker. Is there a smarter way to do this?

Visual Basic is Microsoft’s event-driven programming language and integrated development environment (IDE) for its Component Object Model (COM) programming model. It is relatively easy to learn and use because of its graphical development features and BASIC heritage. It has been replaced with VB.NET, and is very similar to VBA (Visual Basic for Applications), the programming language for the Microsoft Office product line.
