如何从任务栏最小化和最大化Winform？

Question

I have a Winforms application, which I'm able to minimize by clicking on the corresponding button on the top right of the window; I can then maximize it by clicking on this application's taskbar icon.

My problem is that if the window is maximized, it should be minimized when I click on the taskbar icon again, and it's currently not happening.

How can I make this behavior happen? I don't want to have to use NotifyIcon or system tray.

Answer 1

const int WS_MINIMIZEBOX = 0x20000;
const int CS_DBLCLKS = 0x8;
protected override CreateParams CreateParams
{
    get
    {
        CreateParams cp = base.CreateParams;
        cp.Style |= WS_MINIMIZEBOX;
        cp.ClassStyle |= CS_DBLCLKS;
        return cp;
    }
}

您也可以做到无国界..需要额外的编码

Answer 3

Try to check what's going on in LocationChanged , Move , RegionChanged , Resize , ResizeBegin , ResizeEnd , SizeChanged events. Could be that some code in any of these events is blocking the behavior you described.

I am not seeing the described problem on a new empty form.

Update: I am using Window 7 Pro.
