vb.net怎么设置快捷键

新建一个Form1把Form1的KeyPreview改成True

拖入一个Button1到Form1上面

然后加入以下代码

Private Sub Form1_KeyDown(sender As Object, e As KeyEventArgs) Handles Me.KeyDown

If e.KeyData = (Keys.Alt Or Keys.G) Then

Button1.PerformClick() '或者用Button1_Click(Nothing, New EventArgs)

'快捷键Alt+G触发Button1_Click()事件。

End If

End Sub

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

Button1.Size = New Size(180, 23)

Button1.Text = "我被局部快捷键给召唤了~"

End Sub

Q1: 如何用VB.NET设置菜单项的热键

不清楚热键和快捷键是什么区别

1.如果你是指Chrl+S这样的快捷键，可以设置ShortCutKeys属性，属性窗口就有可视化编辑器。

2.如果你是指"保存(S)"，其中s有下划线这样的用Alt+字母来访问的设置，应该在菜单项的Text属性中使用符号。符号后面的字母将被作为快速访问字符，显示的时候不会被显示出来，而字母会自动加上下划线。比如"保存(s)"。

3.和选中标记有关的属性有两个

CheckOnClick 在菜单项上单击时是否改变Checked属性

Checked 设置/获取 菜单项是否被选中

4.设置菜单项的Enabled属性为False
