Sometimes we want to select all the text in the textbox when the textbox control gains focus. This can be achieved through the SelStart and SelLength properties. Specifically, when the object gets focus, it is selected from the front (SelStart=0), and the selected length is the text length (Len (Text1)). The source code is as follows:
Private Sub Text1_GotFocus()
Text1.SelStart = 0
Text1.SelLength = Len(Text1)
End Sub
The GotFocus event occurs when a control gains focus.
