如何覆盖最小化控件？

我想重写最小化控件，而不是将窗口发送到任务栏，它会执行我编写的操作。

基本上，这就是我想要的新的最小化和恢复效果：

    private void ChangeForm(object sender, EventArgs e)
    {
        if (this.WindowState == FormWindowState.Minimized)
        {
            this.Height = 80;
            iDebug.Visible = false;
            mainMenu.Visible = false;
        }
        else
        {
            this.Height = 359;
            iDebug.Visible = true;
            mainMenu.Visible = true;
        }
    }

我尝试在调整大小上触发一个事件来执行此操作，但没有成功

this.Resize += new EventHandler(ChangeForm);

I want to override the minimize control to instead of sending the window to the taskbar it would do what ever I write it to do.

Basicly this is what I wanted my new minimized and restored effects to be:

    private void ChangeForm(object sender, EventArgs e)
    {
        if (this.WindowState == FormWindowState.Minimized)
        {
            this.Height = 80;
            iDebug.Visible = false;
            mainMenu.Visible = false;
        }
        else
        {
            this.Height = 359;
            iDebug.Visible = true;
            mainMenu.Visible = true;
        }
    }

I have tried to fire an Event on the Resize to do this but without success

this.Resize += new EventHandler(ChangeForm);

取消 WinForm 最小化？

刚刚测试了这个，当最小化时，它会使表单缩短 100 像素点击无闪烁。

private const int WM_SYSCOMMAND = 0x0112;
private const int SC_MINIMIZE = 0xf020;

protected override void WndProc(ref Message m) {
    if (m.Msg == WM_SYSCOMMAND) {
        if (m.WParam.ToInt32() == SC_MINIMIZE) {
            m.Result = IntPtr.Zero;
            Height -= 100;
            return;
        }
    }
    base.WndProc(ref m);
}

Cancel A WinForm Minimize?

Just tested this and it will make the form 100 pixels shorter when minimize is clicked without flicker.

private const int WM_SYSCOMMAND = 0x0112;
private const int SC_MINIMIZE = 0xf020;

protected override void WndProc(ref Message m) {
    if (m.Msg == WM_SYSCOMMAND) {
        if (m.WParam.ToInt32() == SC_MINIMIZE) {
            m.Result = IntPtr.Zero;
            Height -= 100;
            return;
        }
    }
    base.WndProc(ref m);
}

最小化命令对于用户来说具有非常明确的含义，不应该被混淆。因此，Winforms 没有相应的事件。但这不是真正的问题，您可以通过重写 WndProc() 来检测任何 Windows 消息。就像这样：

    private void OnMinimize() {
        this.Close();   // Do your stuff
    }
    protected override void WndProc(ref Message m) {
        // Trap WM_SYSCOMMAND, SC_MINIMIZE
        if (m.Msg == 0x112 && m.WParam.ToInt32() == 0xf020) {
            OnMinimize();
            return;        // NOTE: delete if you still want the default behavior
        }
        base.WndProc(ref m);
    }

The Minimize command has a very well defined meaning to a user, it shouldn't be messed with. Winforms accordingly doesn't have an event for it. But not a real problem, you can detect any Windows message by overriding WndProc(). Like tihs:

    private void OnMinimize() {
        this.Close();   // Do your stuff
    }
    protected override void WndProc(ref Message m) {
        // Trap WM_SYSCOMMAND, SC_MINIMIZE
        if (m.Msg == 0x112 && m.WParam.ToInt32() == 0xf020) {
            OnMinimize();
            return;        // NOTE: delete if you still want the default behavior
        }
        base.WndProc(ref m);
    }
