憑證無效

Question

我有視覺工作室2015年的情況..我有下面的代碼：

Private Sub TBwe.Text 
Changed;(ByVal sender As System.Object, ByVal e As System.System.EventArgs) Handles TBWe.TextChanged 

    if Strings.Len(TBWe.Text) = 6 then 
     TBEt.Focus(); 
    End Sub 

我有無效的令牌類，結構或接口

任何機構幫我 ？

Answer 1

這應該工作：

Private Sub TBwe_TextChanged(sender As Object, e As EventArgs) Handles TBWe.TextChanged 

    If Strings.Len(TBWe.Text) = 6 Then 
     TBEt.Focus() 
    End If 
End Sub
