c# - 在 Windows C# dev express 中闪烁

Question

我有一个 Dev Express Windows 窗体应用程序，它有大量的闪烁，尤其是在启动时。

我对它应用了这个修复。

protected override CreateParams CreateParams
{
    get
    {
        CreateParams cp = base.CreateParams;
        cp.ExStyle |= 0x02000000;   // WS_EX_COMPOSITED

        return cp;
    }
}

此代码修复了闪烁问题，但它使用了 30-50 CPU 使用率。

如何解决这个问题？

Answer 1

您可以尝试为表单设置 DoubleBuffered = true 吗？我不确定它是否适用于 DevExpress。您可以找到相同的 MSDN 主题 - How to: Reduce Graphics Flicker with Double Buffering for Forms and Controls

Answer 2

It also depends on what type of controls are on the form. DevExpress has many controls that have a .SuspendLayout() and .ResumeLayout() which prevent flickering and hang-ups while the specific control is being loaded.
