change a control from a subform or after openform command

[walterio]

Hi
How do I change a control from within a called subform? Or how do I return an argument to the calling form?

Ive tried in the subform with »Me.Parent!control«, »Me!Parent!control«, »Forms!Formname!control«. Nothing worked.



Then I tried getting the OpenArgs after the oppening with
»DoCommand.OpenForm "ufSubform", OpenArgs:=Params«,
but OpenArgs ist Null and Params contains only what it had before the open of the subform.

Thanks for your help

I don't understand what you are trying to do.

Are you trying to display on the main form a value (perhaps a total?) which is on the sub form?

[walterio]

yes. on the main form I have a label, which displays a text depending on a condition, which can be changed in the sub form.

[Bob Fitz]

Try something like:

Parent.LabelName.Caption = "Text to be Shown"

In the AfterUpdate event of the control on the sub form

[walterio]

This is the code:
Parent.Freigabestatus.Caption = "soso"
and it results in a runtime error 2452: The expression you entered has an invalid reference to the Parent property.

I also tried Parent.Freigabestatus!Caption an other combinations of . !

And I use in in the click Event of a command button, but I don't think that matters..

The error message is telling you that the form containing the control which is firing the code doesn't have a parent form. So, is the "subform" actually a subform control on the main form or is this "subform" just another form which was opened when the main form was opened.

If it is a proper sub form, I would suspect that something is corrupt. Perhaps you could post a copy of the db.

[walterio]

It is a sub form that opens with a command button.

[Bob Fitz]

It is a sub form that opens with a command button.

Then that is not a sub form.

So, code would be something like:

Forms!NameOfForm.LabelName.Caption = "Text to be Shown"

[walterio]

runtime error 2450 MS A cannot finr the referenced form ...
I'm calling this not-subform from a real sub form. May it be, that that is the problem?
I tried another way: this not-subform is called with some arguments in OpenArgs, so I tried tu use the same wys back. But this doesn't work, OpenArgs is Null.

Please post a copy of the db

[walterio]

ok, give me some minutes.
and by the way: thank you very much for your support.

[walterio]

I'm sorry, but the db is to big, although there is only 1 record in each File...
So I'm attaching only the modules of the 3 forms involved:

• ufAuftrags_Messungen, the sub Form which contains the command button involved in this drama
• ufMessung_Freigabe and ufMessung_Freigegeben, the two called forms, depending on the field "Freigegeben", both permit the swich from one state to the other...

Hope it's not "toooo much information!"

[walterio]

What do you think of my other approach: returning from the forms and thanks to an argument the settings for the Freigabestatus-Field could be defined. Only: how do I get the arguments from a called form?

"Compact and Repair" the db and then compact it to a "Zip" file before trying to attach the db.

[walterio]

ok, but I have to postpone the matter for tomorrow? Thank you for your help, so far.
