推荐答案

由于F1快捷方式已经分配给主MDI表单中的菜单项，因此您不能再在其MDI中使用它儿童表格。



但是，您可以进行一些简单的设置更改以使其正常工作。



我假设您希望F1在主要MDI表单聚焦时执行不同的操作，而在MDI子项聚焦时则执行另一个不同的操作。如果是这样，那么您可以执行以下操作。



首先在主MDI表单中，打开子表单时，删除F1快捷键

Since the F1 shortcut has already been assigned to a menu item in the main MDI form, you cannot use it anymore in its MDI children form.

You can however do some simple settings change to make it work.

I assume you want the F1 do different action while the main MDI form is focused and another different action when the MDI children is focused. If that is so then you can do the following.

First at main MDI form, when opening the children form, remove the F1 shortcut key

Private Sub TestToolStripMenuItem_Click(ByVal sender As Object, ByVal e As EventArgs) Handles TestToolStripMenuItem.Click
        TestToolStripMenuItem.ShortcutKeys = Keys.None
        Dim f As New Form2
        f.MdiParent = Me
        f.Show()
    End Sub

然后当那个孩子n表格关闭，只需分配快捷键

Then when that children form closes, just assign the shortcut key back

Private Sub Form2_FormClosing(ByVal sender As Object, ByVal e As FormClosingEventArgs) Handles Me.FormClosing
       TryCast(Me.MdiParent, MDIForm).TestToolStripMenuItem.ShortcutKeys = Keys.F1
   End Sub

   Private Sub Form2_KeyDown(ByVal sender As Object, ByVal e As KeyEventArgs) Handles Me.KeyDown
       If e.KeyCode = Keys.F1 Then
           'Do stuff
       End If
   End Sub
