DAO Data Control with DB Grid.Validate Event. Save Argument Doesn't Work

Posted on 2001-06-06

Here is the problem:

1. I have a DAO Data control linked  to a database and displayed through a DB Grid..
2. There is a message box in the validate event which pops up a message box when a record is selected for deletion. The message box says that records may not be deleted.
3. The message box does in fact pop up, but the record is still deleted afterwards, even though the Save argument is set to False.
4. I have made sure that the DB Grid property to allow deletions is set to true, in order to allow the box to pop up. In addition both the DB Grid controll and the DAO allow for records to be added. Here is the code in the validate event:

In debug, the vbDataActionDelete action value of 7 seems to be generated alright; however, no value seems to be generated for  the Save. I have tried using Boolean values of 0 or 1 as well.

Private Sub Data1_validate( Action As Integer, Save As Integer)

If Action = vbDataActionDelete then
   MsgBox "You may not delete a record!"
   Save = False
End If

End Sub

Thanks for your consideration of the above.

Unfortunately, the article above only shows the list of action parameter settings. As mentioned, the delete value of 7 is generated, which is mentioned on the chart. What I would like to know is why the Save as Integer argument doesn't seem to work. I can't find anything in the help or article.

Guessing a bit but is that argument one of the 22 additional possible notifications mentioned in the article

I don't think so. I assume that the argument allows the user to back out of the vbAction that triggered the validate. I thought that setting it to false would mean that the action basically is cancelled and not in effect validated. It doesn't seem to work, though.

I don't think it does mean that but I am also not sure what it is. If I have any bright ideas I'll let you know
