Question

我有5个按钮和5个标签。当我的鼠标悬停在按钮上并传递给文本框时，我想获得label.text值。

代码

    Private Sub btnRoomA_MouseHover(sender As Object, e As EventArgs) Handles btnRoomA.MouseHover
        notransaksiMouse = lblTransaksiRA.Text
        textbox1.text = noTransaksiMouse
    End Sub

    Private Sub btnRoomB_MouseHover(sender As Object, e As EventArgs) Handles  btnRoomB.MouseHover
        notransaksiMouse = lblTransaksiRB.Text
        textbox1.text = noTransaksiMouse
    End Sub

    Private Sub btnRoomC_MouseHover(sender As Object, e As EventArgs) Handles btnRoomC.MouseHover
        notransaksiMouse = lblTransaksiRC.Text
        textbox1.text = noTransaksiMouse
    End Sub

    Private Sub btnRoomD_MouseHover(sender As Object, e As EventArgs) Handles btnRoomD.MouseHover
        notransaksiMouse = lblTransaksiRD.Text
        textbox1.text = noTransaksiMouse
    End Sub

    Private Sub btnRoomE_MouseHover(sender As Object, e As EventArgs) Handles btnRoomE.MouseHover
        notransaksiMouse = lblTransaksiRE.Text
        textbox1.text = noTransaksiMouse
    End Sub
