Vb.net 两个“；“期望的表达”；visualbasic中的错误

我正在使用VisualBasic2008。我去发布我的项目，我得到了两个“Expression expected”错误。我对VisualBasic非常陌生-我昨晚才开始学习。守则：

Public Class Form1

Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs)
    WebBrowser1.Navigate("www.zudostudios.com")
End Sub

Private Sub GoBtn1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    WebBrowser1.Navigate(addressTxt.Text)
End Sub

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

End Sub

Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles addressTxt.TextChanged

End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
    TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles addressTxt.TextChanged
End Sub

Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)

End Sub

Private Sub Button3_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
    WebBrowser1.Navigate("www.zudostudios.com")
End Sub

Private Sub Label1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)      Handles Label1.Click

End Sub
End Class

这是一个复制粘贴错误

您已经实现了以下代码

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
    TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles addressTxt.TextChanged
End Sub

但是当调用方法

TextBox1\u TextChanged

时，

处理addressTxt.TextChanged

是无用的

正确的代码应为：

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
    TextBox1_TextChanged(sender, e)
End Sub

我试过那个新密码。我仍然得到2个表达式预期错误。每一个都会让我看到你代码中的“ByVals”。谢谢-尽管如此，我还是想出了如何执行WebBrowser1.refresh（）或其他操作。现在可以了，谢谢：）
