solutions for flashing C # controls

The example in this article describes a workaround for C # control flicker. Share to everyone for your reference. The specific analysis is as follows:

If you're drawing in a form, whether it's a double-cache or not, you'll see that the image flashes constantly as it's updated, and the workaround is to add the following three lines of code to the form's constructor:

In the constructor, add the following lines below:

The code is as follows:

SetStyle (Controlstyles.userpaint, true);

SetStyle (Controlstyles.allpaintinginwmpaint, true); Erase background is forbidden.

SetStyle (Controlstyles.doublebuffer, true); Double buffering

Parameter description:

UserPaint

If true, the control draws itself rather than through the operating system. This style applies only to classes that derive from Control.

AllPaintingInWmPaint

If true, the control ignores WM_ERASEBKGND window messages to reduce flicker. The style should be applied only if the UserPaint bit is set to true.

DoubleBuffer

If true, the drawing is done in the buffer, and the result is output to the screen when finished. A double buffer prevents flicker caused by a control redraw. To fully enable double buffering, you must also set the UserPaint and AllPaintingInWmPaint style bits to true.

I hope this article is helpful to everyone's C # programming.
