excel - How to select the contents of a textbox once it is activated?

Question

I have this simple Userform, where I only have TextBox1 and TextBox2. I enter some text in both of them. Assume the focus is on (the cursor is in) the TextBox2. When I click on TextBox1, I want the whole text in this control to be highlighted (selected). Thus I use this code:

Private Sub TextBox1_Enter()
    With TextBox1
        .SetFocus
        .SelStart = 0
        .SelLength = Len(.Text)
    End With
    MsgBox "enter event was fired"
End Sub

There is a MsgBox at the end which is loaded, that means the event works. However, the text is not highlighted. How to fix this?

I use the Enter event and don't want to use the MouseDown event, because I need the code to also work when the TextBox1 is activated programatically, so I feel the Enter event to be the best choice, as it's fired in both cases! Another drawback of the MouseDown event is: when I click for the second time on the TextBox1, I would not expect the whole text to be highlighted anymore, because the focus was set on the first click and it was not changed after I clicked on the same control for the second time; so in this case I would like the cursor to act normally (not to keep the text marked).

Update
When I click once on the TextBox1, I expect to have this result:
If clicked again, the highlight would be removed and the cursor would be placed in the place where it was clicked.

Can't be more simple than this I guess...

Private Sub TextBox1_MouseDown(ByVal Button As Integer, ByVal Shift As Integer, _
ByVal X As Single, ByVal Y As Single)
    With TextBox1
        .SelStart = 0
        .SelLength = Len(.Text)
    End With
End Sub

Whether you click on the textbox or you tab into it, it will do what you want. To deselect the text, use the arrow keys.

Explanation

If you debug the code you will see that even though you have said .SetFocus, the focus is not on the Textbox. .SetFocus doesn't work in TextBox1_Enter() and you need to have focus for the rest of the code to work. And hence my alternative...

You may also like this version :) This overcomes the limitation of using the mouse in the TextBox

Dim boolEnter As Boolean

Private Sub TextBox1_Enter()
    boolEnter = True
End Sub

Private Sub TextBox1_MouseDown(ByVal Button As Integer, ByVal Shift As Integer, _
ByVal X As Single, ByVal Y As Single)
    If boolEnter = True Then
        With TextBox1
            .SelStart = 0
            .SelLength = Len(.Text)
        End With
        boolEnter = False
    End If
End Sub
