Running Form_open twice

Hi all,

I Got a form with a form_open event. Problem that i have is that this event is ALWAYS run twice instead of the wanted 1 time. This also happens when using the form_load and form_activate events.

Does anybody have any idea what can be done about it? I am using Acces 2000 with VBA 6.0

Thanks a lot :)

[edit] tested some more, this event is ONLY run twice when i use the docmd.openform procedure t open the form, not when openening it manually. Is thewre any other way to open a form in a way that this doesent cause the form_open procedure to be executed twice? [/edit]

Created a workaround it but i still want to know why open form is executed twice when using docmd.openform in VBA, so anyone? :)

where's your procedure code which you open this with? - docmd on it's own just opens the form once...

ill post it tomorrow dont have the code here, but dont expect something strange, i just use docmd.openform :)

If you can post the bit calling this form to open, as well as any procedures of the form which are run when it first starts up, I'll take a look

Ok here it is:

procedure opening form

Code:

---

  Dim bAutoUpdate As Boolean

  ......
 
  If bAutoUpdate Then
    [Form_Update Peak information].GetUpdateInformation
  Else
    DoCmd.OpenForm [Form_Update Peak information].name
  End If
 
  .......
 
End Sub

Thanks for the help :)

no idea from looking through that one - this seems fine to me. Can you try stepping through the code & seeing which lines it's called on ?

When i mark the line where the form is opened and the first line in the procedure "Form_open" and i run it the line where the form is opened is passed 1 time, the first line in the procedure "For_open" twice

I will try step through the whole procedures and find out where the "form open" procedure is executed again...

Doesent seem to execute "open_form" again from within any of the other procedures. Open_form is completely executed and afterwards executed one more time.

So u also have no idea what can cause this?
