< blockquote>谢谢你，但我得到了答案，这是

< br /> 
 Private Sub TabControl1_SelectedIndexChanged（sender As Object，e As EventArgs）Handles TabControl1.SelectedIndexChanged< br /> 
< br /> 
'抓取Web浏览器控件在此选项卡上并读取其URL属性< br /> 
'注意，只希望获得一个浏览器控件。< br /> 
< br /> 
每个wb作为WebBrowser在TabControl1.SelectedTab.Controls.OfType（Of WebBrowser）中（< br /> 
 urlTextBox.Text = wb.Url.ToString< br /> 
 Next< br /> 
 End Sub< ; br /> 

以上确实假设你只有每个TabPage上有一个WebBrowser控件。如果不是这种情况，还有其他方法可以找到WebBrowser控件。

I have a tabbed web browser its working fine , but i have a little problem and that is if i open a new tab is ok but if i go back to previous tab the urltextbox it have the url in the tab last opened tab.
so i am asking you for help if you have the solution

解决方案

This help you. Link[^]

thank you any way but i got the answer and it is

<br />
Private Sub TabControl1_SelectedIndexChanged(sender As Object, e As EventArgs)      Handles TabControl1.SelectedIndexChanged<br />
<br />
    'Grab the Web Browser control on this tab and read its URL property<br />
    'NOTE, only expect to get one browser control.<br />
<br />
    For Each wb As WebBrowser In TabControl1.SelectedTab.Controls.OfType(Of WebBrowser)(<br />
        urlTextBox.Text = wb.Url.ToString<br />
    Next<br />
End Sub<br />

The above does assume that you would only have one WebBrowser control on each TabPage. There are other ways of finding the WebBrowser control if this is not the case.
