Question

我有点卡住并试图在文档准备好时触发事件。你知道我做错了吗？

Public Class Form1
'Declaration
Public Event DocumentCompleted As WebBrowserDocumentCompletedEventHandler

Private Sub Main(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    'Dim frm As New Form1
    'frm.Show()
    WebBrowser1.Navigate("http://test.com")
    AddHandler WebBrowser1.DocumentCompleted, New  _
         WebBrowserDocumentCompletedEventHandler(AddressOf WebBrowser1_DocumentComplete)
    Me.Text = WebBrowser1.ReadyState

End Sub

Private Sub WebBrowser1_DocumentComplete(ByVal sender As Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles Me.DocumentCompleted
    Me.Text = WebBrowser1.ReadyState
End Sub

End Class

您需要在调用导航方法之前添加处理程序：

AddHandler WebBrowser1.DocumentCompleted, New  _
     WebBrowserDocumentCompletedEventHandler(AddressOf WebBrowser1_DocumentComplete)
WebBrowser1.Navigate("http://test.com")

如何检测WebBrowser Control的documentready事件？
