Lav knap der åbner en anden form på ny post og opdaterer når man lukker

What is to update on form1?

There's a link here which I think may be of use to open form.

Answer really depends on whether or not you only want to add new records or also be able to edit existing.

An dif you open form 2 as dialog then you can also put a requery of form 1 after the line of code which opens form 2

...What is to update on Form1?

Form1 contain several combo-boxes that link to tabels (ex. CusomerTable)

I have made a button in Form1 that opens Form2 (Add customer).

When I add a new customer via Form2 and close it, the new date does not apear in the customer-combo-box in Form1. Not untill I press update in the toolbar.

Can this be done automatic via the "Close button" on Form2"?

Though that might be the reason :-)

There's actually an event which you can use to trigger your code.

Some good examples here

and that was an answer :-)

I dont think that's what Im looking for..
Actually I dont undestand much of it.

What I need is to update Form1 with some kind of action fra a button on Form2.

Is that possible?

"Actually I dont undestand much of it." :-)

But it is actually the right way to do it, and you cant always get away from having to write code.

If you have a number of combo boxes then I guess you have a number of forms you want to open to add for example a new customer.

In the code which open the form, make sure it opens the form as a dialog. THis way the form must be closed before the code continues in form 1

EG: DoCmd.OpenForm "frmSales", acDialog ...

Now after this line of code you can requery your combo.

EG: Me.MyCombo.Requery


So you dont need to updatye form 1 from form 2

I hope you got something to work, and thanks for the points
