Visual Basic - 带有RichTextBox和计时器的进度条

Question

我想制作带有进度条和richtextbox的计时器。 如果％，则打印加载信息。

我有：

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick

        If MephProgressBar2.Value = 15 Then RichTextBox1.Text = RichTextBox1.Text & "Loading jakiśtam2.dll..." & vbCrLf
        If MephProgressBar2.Value = 25 Then RichTextBox1.Text = RichTextBox1.Text & "Loading jakiśtam4.dll..." & vbCrLf
        If MephProgressBar2.Value = 45 Then RichTextBox1.Text = RichTextBox1.Text & "Loading 7567567..." & vbCrLf
        If MephProgressBar2.Value = 55 Then RichTextBox1.Text = RichTextBox1.Text & "Loading Lollol.dll..." & vbCrLf
        If MephProgressBar2.Value = 80 Then RichTextBox1.Text = RichTextBox1.Text & "Można wpisywać co się chce" & vbCrLf
        If MephProgressBar2.Value = 86 Then RichTextBox1.Text = RichTextBox1.Text & "BlaBlabla" & vbCrLf
        If MephProgressBar2.Value = 95 Then RichTextBox1.Text = RichTextBox1.Text & "Make-cash.pl" & vbCrLf
    End Sub

但它没有用。我得到了错误：     预期结束。

这是我的代码：

Public Class Form1

    Private Sub MephProgressBar2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MephProgressBar2.Click

    End Sub

    Private Sub MephButton1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MephButton1.Click
        Timer1.Start()

    End Sub

    Private Sub RichTextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RichTextBox1.TextChanged

    End Sub

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick

        If MephProgressBar2.Value = 15 Then RichTextBox1.Text = RichTextBox1.Text & "Loading jakiśtam2.dll..." & vbCrLf
        If MephProgressBar2.Value = 25 Then RichTextBox1.Text = RichTextBox1.Text & "Loading jakiśtam4.dll..." & vbCrLf
        If MephProgressBar2.Value = 45 Then RichTextBox1.Text = RichTextBox1.Text & "Loading 7567567..." & vbCrLf
        If MephProgressBar2.Value = 55 Then RichTextBox1.Text = RichTextBox1.Text & "Loading Lollol.dll..." & vbCrLf
        If MephProgressBar2.Value = 80 Then RichTextBox1.Text = RichTextBox1.Text & "Można wpisywać co się chce" & vbCrLf
        If MephProgressBar2.Value = 86 Then RichTextBox1.Text = RichTextBox1.Text & "BlaBlabla" & vbCrLf
        If MephProgressBar2.Value = 95 Then RichTextBox1.Text = RichTextBox1.Text & "Make-cash.pl" & vbCrLf

    End Sub
End Class
