Flicker problem (looping)

[vbSteve]

Hi,

I'm trying to move around a circle on a Picturebox, which i called "myPictureBox". It works, though with a fast pulse flicker. I know that in VB6 you could put the AutoDraw of the picturebox to True to solve this, but VB .Net apperantly doesn't have this. (I recently made the switch to VB .NET)

I was wondering how it can be solved. The code is as followed (Simplified):

Dim TaskManager As New class_taskmanager
Dim g As Graphics
Dim tPen As New Pen(Color.Blue, 1)
Dim x As Integer, y As Integer, w As Integer = 10, h As Integer = 10
Dim bRunning as Boolean = True

g = myPicBox.CreateGraphics()

While bRunning
 g.clear(Color.Black)

 bRunning = PlayerThink(x, y)  ' Return x, y for next position
 g.drawEllipse(tPen, x, y, w, h)
 TaskManager.WaitingTask(0.041, "seconds", true) ' Set to 24 Frames/Sec (1/24 = 0.041667) 
Wend

Many thanks in advance,
Steve

Try something similar to this: http://msdn2.microsoft.com/en-us/library/system.windows.forms.control.setstyle(vs.80).aspx

In any case, I guess you would have to create a control inheriting from PictureBox, and set it's ControlStyles.DoubleBuffer to True. After that, just use it as you would a normal PictureBox.

I'll try to handle it this way then
