如何检测是否按下了特定键？

Question

我想知道是否有办法检测是否按下了特定键(如退格键).这是我正在拍摄的:

Private Sub SomeTextBox_Change()

    If len(Me.SomeTextBox.Value) = 3 and KEYPRESSED is NOT BACKSPACE Then
         <.......Code Here>
    Else
         <.......Code Here>
    End if

End Sub

Answer 1

您应该使用KeyPress事件而不是Change事件:

Private Sub TextBox1_KeyPress(ByVal KeyAscii As MSForms.ReturnInteger)

    If Len(Me.SomeTextBox.Value) = 3 And KeyAscii <> 8 Then 'Backspace has keycode = 8.
         <.......Code Here>
    Else
         <.......Code Here>
    End If

End Sub

Answer 2

本示例将“InsertProc”分配给按键序列 CTRL+PLUS SIGN，并将“SpecialPrintProc”分配给按键序列 SHIFT+CTRL+RIGHT ARROW。

Application.OnKey "^{+}", "InsertProc" 
Application.OnKey "+^{RIGHT}","SpecialPrintProc"

Answer 3

Private Sub TextBox1_KeyDown(ByVal KeyCode As MSForms.ReturnInteger, ByVal Shift As Integer)

If KeyCode.Value = vbKeyF1 Then
       MsgBox "F1 is pressed"
    End If
End Sub
