推荐答案

我刚刚在MDIParent和MDIChild表单上都尝试过此操作，但是如果将MaximiseBox属性设置为FALSE，则双击标题栏不会执行任何操作，设置如果设置为TRUE，则表示双击将使被单击的窗口最大化. I have just tried this on both the MDIParent and MDIChild forms, but if you set MaximiseBox property to FALSE, double clicking the titlebar does nothing, setting it to TRUE means a double click causes the clicked window to maximise.

我认为以下内容可能会对某人有所帮助，因为它对我来说非常有效... I think the below might be of some help to someone, since it worked very finely for me... Protected Overloads Overrides Sub WndProc(ByRef m As Message) 'Define DoubleClick... Const WM_NCLBUTTONDBLCLK As Integer = &HA3 'Define LeftButtonDown event... Const WM_NCLBUTTONDOWN As Integer = 161 'Define MOVE action... Const WM_SYSCOMMAND As Integer = 274 'Define that the WM_NCLBUTTONDOWN is at TitleBar... Const HTCAPTION As Integer = 2 'Trap MOVE action... Const SC_MOVE As Integer = 61456 'Disable moving TitleBar... If (m.Msg = WM_SYSCOMMAND) AndAlso (m.WParam.ToInt32() = SC_MOVE) Then Exit Sub End If 'Track whether clicked on TitleBar... If (m.Msg = WM_NCLBUTTONDOWN) AndAlso (m.WParam.ToInt32() = HTCAPTION) Then Exit Sub End If 'Disable double click on TitleBar... If (m.Msg = WM_NCLBUTTONDBLCLK) Then Exit Sub End If MyBase.WndProc(m) End Sub

谢谢大家

Thanks guys

尝试一下: Try this: private void Form1_Resize(object sender, EventArgs e) { if (WindowState == FormWindowState.Maximized) { WindowState = FormWindowState.Normal; } }

唯一的麻烦是它可能会闪烁:窗口将短暂最大化，然后恢复正常.

The only slight hassle is that it may flicker: the window will be maximized briefly, and then returned to normal.
