Question

我想编写一个按钮，经过3次点击后，将用户链接到我的网站。前2个应该在文本框中生成一个代码，然后最后一个应该链接它们。这就是我到目前为止所拥有的

Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
    ProgressBar1.Increment(3)
    If ProgressBar1.Value = 100 Then
        TextBox1.Text = "Thank you"
        Timer1.Stop()
    End If
End Sub

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    If RadioButton1.Checked = True Then
        Timer1.Start()
    ElseIf RadioButton2.checked = True Then
        Timer1.Start()
    Else
        TextBox1.Text = "Please Select Option"
    End If
End Sub

Answer 1

我不知道ProgressBar和Timer的用途是什么。但是如果你想知道用户点击按钮的次数，计数器变量就应该这样做。

Private _clickCounter As Integer

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    _clickCounter += 1

    If _clickCounter = 3 Then
        MsgBox("3 times")
        _clickCounter = 0
        'link to your site
    Else
        'generate code in textbox
    End If
End Sub

Answer 2

使用一个整数，每次单击该按钮时都会增加一个整数，并使用Select Case语句来检测该按钮;

Dim NumberOfClicks As Integer = 0

Dim webAddress As String = "http://www.YourWebsite.com/"

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
 number = number + 1
 Select Case number
      Case 1
          ''''' Code for your textbox
      Case 2
          ''''' Code for your textbox
      Case 3
           Process.Start(webAddress)
End Sub

这应该做。如果有帮助，请将我的答案标记为已解决。
