Hi @Liu Hao ,

Ensure that tabElement actually supports the SelectionItemPattern.

If tabElement.TryGetCurrentPattern(SelectionItemPattern.Pattern, selectInvoke) Then
    selectInvoke.Select()
Else
    ' Handle the case where the pattern is not supported
End If

Try verifying that the tabElement is ready by checking properties like tabElement.Current.IsEnabled and tabElement.Current.IsOffscreen.

Best Regards.
