This article describes the solution to the flashing of C# controls. Share it for your reference. The specific analysis is as follows:
If you draw in Form, regardless of whether you use double cache or not, you will see that the image will keep flashing when updated. The solution is to add the following three lines of code to the constructor of this form:
Please add the following lines under the constructor:
SetStyle(, true); // Erase background is prohibited.
SetStyle(, true); // Double buffering
Parameter description:
UserPaint
If true, the control will draw itself instead of through the operating system. This style is only applicable to classes derived from Control.
AllPaintingInWmPaint
If true, the control ignores the WM_ERASEBKGND window message to reduce flickering. This style should be applied only if the UserPaint bit is set to true.
DoubleBuffer
If true, the drawing is performed in the buffer, and the result is output to the screen after completion. Double buffers prevent flickering caused by control redrawing. To enable double buffering completely, you must also set the UserPaint and AllPaintingInWmPaint style bits to true.
I hope this article will be helpful to everyone's C# programming.
