我已为所有mdi子窗体应用了背景图片.

但是，当我单击子窗体时，会出现闪烁效果.

我希望删除它.

Sirs,

I have an MDI form with many child forms.

I have applied a background image for all mdi child forms.

However, when I click the child form I get a flicker effect.

I wish to remove this.

How could I avoid this problem?

推荐答案

在窗体中的InitializeComponent之后，立即添加以下命令:

Immediately after InitializeComponent in your forms, add the following command:

this.SetStyle(
  ControlStyles.AllPaintingInWmPaint |
  ControlStyles.UserPaint |
  ControlStyles.DoubleBuffer,true);
