สอบถามเรื่อง Event form ของ C# ลองหาๆดูไม่เจอสักทีครับ

Private Sub Form1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles MyBase.MouseDown

 

        If e.Button = MouseButtons.Left Then

            Button5.Enabled = True

        ElseIf e.Button = MouseButtons.Right Then

            Button3.Enabled = True

        ElseIf e.Button = MouseButtons.Middle Then

            Button4.Enabled = True

        End If

 

End Sub

 

 

Private Sub Form1_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles MyBase.MouseUp

 

        If e.Button = MouseButtons.Left Then

            Button5.Enabled = False

        ElseIf e.Button = MouseButtons.Right Then

            Button3.Enabled = False

        ElseIf e.Button = MouseButtons.Middle Then

            Button4.Enabled = False

        End If

 

End Sub
