When/how to clear a filter

I have two forms:
1. A search Input form (with a search button that starts my code)
2. A results form that consists of a master form that has some "function" buttons and a subform within which the results are displayed in a datasheet

When the user clicks Search, the code examines all of the possible parameters and creates the "where" clause for the ResultsSub form; however, I can't get it to forget the filter once the ResultsMain/Sub form closes. So if the user clicks the "back to search" or "main menu" button on the ResultsMain, it doesn't drop the filter.  I currently have a command in the ResultsSub form at the "on close" event to set the filter to nothing:
me.filter = ""
but it isn't working.

When / where should i put the me.filter = ""  command?

thanks

I have Access 2007/2010 pain too.
In Access 2003 a filter does not survive opening and closing.
They do in 2007/2010, and I run a mixed environment

ClearFiltersonOpen clears any filters as a form opens
To be clear, it runs in the Form Open event.

KillFilters gets used before I put out a production version to kill any filter on any form.
It opens every form in design mode, sets the filter to "" , saves the form and closes it.

Curses on those who invented FilterOnLoad!
'in the forms module
Private Sub Form_Open(Cancel As Integer)
Call ClearFiltersonOpen(Me.Name)
End Sub


'-----------------------------------------------------------------

'in a regular module

Public Function ClearFiltersonOpen(FormName As String)
'Because Access 12+ allows a filter of survive opening and closing a form
'it becomes necessary to kill filters

Forms(FormName).Filter = ""
Forms(FormName).FilterOn = False


End Function


'-----------------------------------------------------------------


Private Sub KillFilters()
'On Error GoTo myerr
Dim f As AccessObject
Dim MyProject As Object
Dim myform As Form
Set MyProject = Application.CurrentProject
For Each f In MyProject.AllForms
    DoCmd.OpenForm f.Name, acDesign
    'MsgBox Nz(Forms(f.Name).Filter, "no filter")
    Forms(f.Name).Filter = ""
    Forms(f.Name).FilterOn = False
    DoCmd.Close acForm, f.Name, acSaveYes
Next f
        
Exit Sub

myerr:
'MsgBox Err.Number & " " & Err.Description
Resume Next

End Sub

Try clearing it prior to each new search ... in the Search button Code.

Me.YourSubFormControlName.Form.Filter = ""
Me.YourSubFormControlName.Form.FilterOn = False

' other search code ...

'  set new filter.

You mention: When the user clicks Search, the code examines all of the possible parameters and creates the "where" clause for the ResultsSub form

Does this actually modify the "WHERE" clause of the SQL string that is the Recordsource for the subform, or does it modify the Filter property of the subform?  If it modifies the WHERE clause, setting the "Filter" property to "" will not do anything for you.

@DBMX: can I set that form filter property if that form is not open? Because that form won't be open when the call is made.

@ fyed: I pass the where clause via open args and the clause ends up in the Filter property of the form.

thanks all!

so to clarify the forms:

I have a Search form

I have a Results form.

they're two different forms. the Results form consists of a Master and Sub form.

I'm afraid not.  Form needs to be open.

"I pass the where clause via open args and the clause ends up in the Filter property of the form."
You really just need to pass either a Filter string OR a WHERE clause ... like so:

DoCmd.OpenForm "YourFormName",acFormDS ,, <WHERE CLAUSE HERE>

The WHERE Clause will do the filtering ...
