Hi Lennox,

By doing so, you have to be aware of a fact (if it's relevant for what you're doing).

If you change your text, then simply switch to the Finder to make anything and then switch back, the remembered text will be the one after the switch (because the Activate event is called not only when a document is opened, but also when the window is simply brought to the front). Same fact apply if you simply move to another edit field (assuming there is more than one) and then come back to your target edit field.

The activate event for opening an existing document

I think it'll be more reliable to do it in the same method where you open your document (maybe just call another function).

and the got focus for changes in an already open document.

You're certainly doing something I don't understand here.

Hope this helps

Hi Arnaud,

I did not put it in the Open event, but I put it in the Activate and got focus events.

Works great.

Make a property in your window, for example: MyLastText As String

Then, for the example, put this code in the open event (when the text
you want as the default is in the edit field):

MyLastText=me.text

In your push button, write EF1.text=MyLastText (assuming your
editfield is named EF1).

Hope this help

Hello,
I have an editfield with some text in it. Then I change (select
then Enter) some of the text. I now want to Undo that.
I have a pushbutton named Undo, what do I put in  Undo pushbutton's
action event?
Thanks.
Lennox
