某些不支持视觉样式的应用程序(例如GoToMeeting)禁用了视觉样式,并且在GoToMeeting运行时错误地绘制了我的表单(Aero客户端区域被绘制为黑色).

我如何订阅禁用视觉样式时触发的OS事件？然后我可以调整窗口中的客户区域以正确绘制.

托管和非托管解决方案对我有效.

提前致谢.

编辑：根据Hans的回答,这是管理此事件的代码：

private const int WM_DWMCOMPOSITIONCHANGED = 0x31e;

[DllImport("dwmapi.dll")]
private static extern void DwmIsCompositionEnabled(ref bool pfEnabled);

protected override void WndProc(ref Message m)
{
    if (m.Msg == WM_DWMCOMPOSITIONCHANGED)
    {
        bool compositionEnabled = false;
        DwmIsCompositionEnabled(ref compositionEnabled);

        if (compositionEnabled)
        {
           // composition has been enabled
        }
        else
        {
           // composition has been disabled
        }
    }

    base.WndProc (ref m);
}
