vb.net组合键

Question

我试图在 VB.net 应用程序中捕获两个按键，对于本例 CTRL + B，下面的代码不起作用，但它适用于单个按键。我尝试将 keypreview 设置为 true 但这没有效果。

  Private Sub main_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles mybase.KeyDown
            If e.KeyCode = Keys.ControlKey And e.KeyCode = Keys.B Then
                MsgBox("CTRL + B Pressed !")
            End If
        End Sub
    End Class

谢谢

Answer 1

Control 键是修饰键。此代码测试 Ctrl + B

e.KeyCode = Keys.B AndAlso e.Modifiers = Keys.Control

键码是 B，但修饰符是 Ctrl。

您的代码片段已更新:

Private Sub main_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles mybase.KeyDown
    If (e.KeyCode = Keys.B AndAlso e.Modifiers = Keys.Control) Then
        MsgBox("CTRL + B Pressed !")
    End If
End Sub
