You have two ways to do it
你有两种方法可以做到
SelectedTab:
MyTabControl.SelectedTab = MyTabPage(The TabPage you want to select)SelectedIndex:
MyTabControl.SelectedIndex = 1(1 is the index of the second TabPage)
所选标签：
MyTabControl.SelectedTab = MyTabPage（您要选择的 TabPage）选定索引：
MyTabControl.SelectedIndex = 1（1为第二个TabPage的索引）

Here is my approach, I trust someone will find it helpful, using My.Settings:
这是我的方法，我相信有人会发现它有用，使用 My.Settings：
Code for the exit button/routine:
退出按钮/例程的代码：
Private Sub PicClose_App_Click(sender As Object, e As EventArgs) Handles PicClose_App.Click
' Save the current active tab index, this will be used on next startup to determine on which TabPage to start
My.Settings.Main_Form_Startup_TabPage = MyTabControl.SelectedTab.TabIndex
Application.Exit()
End Sub
Code called from the Load event of the main form:
从主窗体的 Load 事件调用的代码：
Public Sub Form_Startup_TabPage()
' Get tab index from settings, 0 has been set as default
Dim IntStartup_TabPage As Integer = My.Settings.Main_Form_Startup_TabPage
' Select the last tab used
FrmMain.TabChar_Group_Selection.SelectedIndex = IntStartup_TabPage
End Sub
