How to set focus to a field on subform which is placed on a tab of the mainform

[Pierkes]

Hi,

I have a

- mainform called: [frm_traject_det ails]
- a page on the mainform called: [page_status - resultaat]
- a subformelement (for displaying subform) called: [Redenen van winst of verlies]
- a subform called frm_reden

- a combobox on the subform called: cmb_reden_cat

When a certain criteria is not met, i want to show a message and set the focus to a field on the subform.

On the page i have a field in which, in the BeforeUpdate procedure, i have;

Private Sub Form_beforeupdate(Cancel As Integer)
DoCmd.Echo True
Dim ctl As Control

If Me![Status Res] <> 5 And Me![Soort traject] < 6 And Me![chk_reden] = False Then
MsgBox ("Het resultaat van dit traject is " & [Status Res].Column(1) & ", geef aan wat de reden(en) hiervoor zijn aub!")
Me.[Redenen van winst of verlies].SetFocus
Me.[frm_redenen].SetFocus
Me.[Redenen van winst of verlies]!cmb_reden_cat.SetFocus
Cancel = True
Exit Sub

End If

It will generate an error message stating it cannot set focus to [Redenen van winst of verlies]

Any suggestions ?

Thanks,
Pierkes

Pierkes,
Here is a page a lot of us refer to for help with form/subform references

If you are calling the Form_beforeupda te from the main form, I think you want to replace lines 7-9 with:

Me![Redenen van winst of verlies].Form![cmb_reden_cat].SetFocus

So you would end up with:

Private Sub Form_beforeupdate(Cancel As Integer)
 DoCmd.Echo True
 Dim ctl As Control
 
 If Me![Status Res] <> 5 And Me![Soort traject] < 6 And Me![chk_reden] = False Then
 MsgBox ("Het resultaat van dit traject is " & [Status Res].Column(1) & ", geef aan wat de reden(en) hiervoor zijn aub!")
 Me![Redenen van winst of verlies].Form![cmb_reden_cat].SetFocus
 Cancel = True
 Exit Sub
 
 End If

Access's syntax can get a little ugly.
