Referencing one form from another

[joancabianna]

Hello,

What I am trying to do is have one form loop through its combo boxes and check to see if the value is a key word like Query_Form or Query_Form2. What I then want to happen is in either case to call another form that does on the fly calculations and then stores them in separate queries.

On this new calculation form I want to have a way of saying something along the lines of
If 'the other form' says Query_Form .. then call this version of the query
ElseIf 'the other form' says Query_Form2 ... then call this version of the query

My Code so far is as follows..

For the first form:

  For i = 1 To 29
        If Me.Controls("cboField" & i) = "Query_Form" Then
        'Opens frmVarCalc form as a dialog box so user must take action before rest of code is run
        DoCmd.OpenForm "frmVarCalc", , , , , acDialog
        ElseIf Me.Controls("cboField" & i) = "Query_Form2" Then
        DoCmd.OpenForm "frmVarCalc", , , , , acDialog
        End If
    Next i

For the calculation form I then have:

If Forms!Make_Report.Controls() = "Query_Form" Then
    Call fCreateQueries("VarCalc_Query")
    Call fCreateUpdateQueries("Update_Projects")
ElseIf Forms!Make_Report.Controls() = "Query_Form2" Then
    Call fCreateQueries("VarCalc_Query_Two")
    Call fCreateUpdateQueries("Update_Projects_Two")
End If

I know the mistake is most likely in the Forms!Make_Repo rt.Controls() statement, but I don't know how to check which combo box on the other form it is.

Any help would be greatly appreciated. Thanks!

Hi. You can refer to controls on another form by providing the name of the control just as you have done within the main loop:

Forms!formname. Controls(contro lname) or
Forms(formname) .Controls(contr olname) amongst others.

However, if you don't know which control name to refer to it would suggest that your current design is somewhat flawed. If it is not apparent to you how is it going to be for your users?

Looping through 29 controls on one form to check whether or not to use some form of query by form is required seems a bit odd really, but without knowing more about why you are doing so I can't comment further.

The reason I need to loop through the comboboxes is because they help set fields for a dynamic report and the user will want to change which columns fall where each time they create the report.

Thanks for your help, I've found a post that suggests setting a global variable to be either Query_form or Query_form2 so that the second form can reference it. So far it seems to be working!

Thanks again!
