IMO正确的方法是通过Form1中的属性
公开所选标签。
''输入消息
公共类Form1
Public Property SelectedTab As TabPage
获取
返回Me.TabControl1.SelectedTab
结束获取
设置（ByVal值为TabPage）
Me.TabControl1.SelectedTab = TabPage < br $>
结束集
结束物业
结束班
公共类Form2
Public Sub MyMethod（）
Dim f As New Form1（）
f.Show（）
Dim tp As TabPage = f.SelectedTab
MessageBox.Show（tp.Name）
End Sub
End Class
谢谢，

谢谢Seth，
但我在Set语句中收到错误...
> Me.TabControl1.SelectedTab = TabPage
它说TabPag是一种类型，不能用作表达式

嗯...
我的TabPage是动态添加的（w我没有陈述）...所以问题
可能就在我的最后。

Let''s say you open Form1 that contains TabControl1
There are several tabs on TabControl1
Now you open a new Form2 that contains a User Control
How can you determine the Selected tab in Form1 from the User Control in
Form2 ?
Hope this is clear enough...
Thanks !

Thanks !IMO the proper way would be to expose the selected tab via a property
in Form1.
'' Typed in message
Public Class Form1
Public Property SelectedTab As TabPage
Get
Return Me.TabControl1.SelectedTab
End Get
Set (ByVal value As TabPage)
Me.TabControl1.SelectedTab = TabPage
End Set

Public Class Form2
Public Sub MyMethod()
Dim f As New Form1()
f.Show()
Dim tp As TabPage = f.SelectedTab
MessageBox.Show(tp.Name)
End Sub

Thanks Seth,
But I am getting an error in in the Set statement...
> Me.TabControl1.SelectedTab = TabPage
It says "TabPag is a type and cannot be used as an expression"

Hmmm...
My TabPage was dynamically added (which I did not state)...so the problem
is probably on my end.
