Graphics and Double Buffering - Visual Basic .NET

Simon Jefferies

Hello,

I am using the Paint event to draw graphics, but I am getting annoying flickering. Is there anyway to perform double-buffering?

I have looked at creating a bitmap, but is limited in what I can do with it.

Any ideas?

Thanks

Simon,
Include the following in your Form or Control's constructor.

' Stop the flicker
Me.SetStyle(Con trolStyles.User Paint, True)
Me.SetStyle(Con trolStyles.Doub leBuffer, True)
Me.SetStyle(Con trolStyles.AllP aintingInWmPain t, True)
Me.SetStyle(Con trolStyles.Resi zeRedraw, True)
Me.UpdateStyles ()

This needs to be in the class you are painting ON, which can be different
then the object where the paint handler is. I normally handle the Paint
event in the same class that I am painting on.

Hope this helps
Jay

Graphics and large images

by: bullshark | last post by:

I have a C# application that manipulates images. The application provides the ability to pan around the images. Normally you can "grab" the image and move it around and it moves in real time with the mouse cursor. There is very low friction. It slides easily. My problem is that with larger images, it just turns to mud. Refreshing the image, or re-drawing a screenful take so long that trying to pan the image results in jumpy, jerky...

Graphics ... almost working ... missing one line?

by: Peter Webb | last post by:

I previously asked about two problems I had with some graphics - the first was that when I drew animation to a picturebox it wouldn't display when the Form loaded. It was suggested to me by everyone that I stop using my own CreateGraphics calls, and override an OnPaint call to do this. As suggested, I created a custom control "drawBox" with an override on its OnPaint. Because I am using manual double buffering, as people suggested it was...

The easy way to turn off automatic updates for Windows 10/11

by: Hystou | last post by:

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
