同時按下多個按鍵

Question

當多個按鍵同時按下時，如何發送字符串/消息框？ 我試過And以及Andalso，但結果是隻有第一個密鑰才需要彈出msgbox。

Protected Overrides Function ProcessCmdKey(ByRef msg As System.Windows.Forms.Message, _ 
             ByVal keyData As System.Windows.Forms.Keys) _ 
             As Boolean 
     If msg.WParam.ToInt32() = CInt(Keys.ShiftKey) AndAlso CInt(Keys.A) Then 
      MsgBox("Testing") 
      Return True 
     End If 

     Return MyBase.ProcessCmdKey(msg, keyData) 
End Function

你可以簡單地做：

Protected Overrides Function ProcessCmdKey(ByRef msg As System.Windows.Forms.Message, _ 
            ByVal keyData As System.Windows.Forms.Keys) _ 
            As Boolean 
    If keyData = (Keys.Shift Or Keys.A) Then 
     MessageBox.Show("Shift-A") 
     Return True 
    End If 

    Return MyBase.ProcessCmdKey(msg, keyData) 
End Function 

注意，這
