How to change record source in a report via vba

I have the following question.

I have a report that is suposed to run once for a series of 5 vendors.  Right now I have 5 reports; one for each of the 5 vendors.  Each report has a query as its record source.

I have   rpt_vendor1,   rpt_vendor2,   rpt_vendor3, rpt_vendor4,  and   rpt_vendor5  as my report names.

The query names are:

qry_vendor1
qry_vendor2
qry_vendor3
qry_vendor4
qry_vendor5


What I would like to do is open a report in design view using a Docmd.  After the report is open, I want to be able to change the record source and run the report for each of the 5 vendors, in a loop if possible

I can open the report, but cannot figure out how to change the record source, print the report, change the record source for the next vendor and print the report, etc.

I tried a few things using me! but could not get anything to work.

Please help

Pass in each queryname as part of the openreport statement eg.

  for i = 1 to 5

   myQueryName="qry_vendor" & i
   docmd.OpenReport "reportname",,,,,myQueryName

  next

Then interrogate the OpenArgs property within the report's Open event:

  if me.openargs & "" <> "" then me.recordsource=me.openargs





You could call each in sucession passing the query name in the open args (like rockmuncher suggested), the code here will open the report in previewe mode and wait until the user closes it before previewing the next one

Call OpenReportAndWait("rptVendor", strArgs)


I would use slightly different test for the report open event

Private Sub Report_Open(Cancel As Integer)
    If Len(Me.OpenArgs & vbNullString) > 0 Then
        Me.Record1Source = Me.OpenArgs
    End If
End Sub

Private Sub OpenReportAndWait(ReportName As String, OpenArgs As String)
    Dim lngLoop As Long
    Dim blnClosed As Boolean
   
    DoCmd.OpenReport ReportName:=ReportName, _
                     View:=acViewPreview, _
                     OpenArgs:=WhereCondition
   
    'loop until user closes the report
    Do
        'only check every 1000 loops
        If lngLoop Mod 1000 Then
            'let foreground process execute
            DoEvents
            'is the report still open?
            If Reports.Count > 0 Then
                blnClosed = False
            Else
                blnClosed = True
                Exit Do
            End If
            lngLoop = 0
        End If
        lngLoop = lngLoop + 1
    Loop
End Sub

Rockmuncher,

When you interrogate, I have a few questions:

You say to use the code:

if me.openargs & ""<>"" then me.recordsource=me.openargs

I tried this a variety of ways and it did not work.  What does ""<>"" mean?  Was I supposed to use this exact syntax or am I not understanding something.  Also, should this statement come below next like in your example or above next or does it not matter.

Thanks
rockmuncher was saying that you need to add code to your report's Open event and both our code examples do the same thing ...

mine
Private Sub Report_Open(Cancel As Integer)
    If Len(Me.OpenArgs & vbNullString) > 0 Then
        Me.Record1Source = Me.OpenArgs
    End If
End Sub

his
Private Sub Report_Open(Cancel As Integer)
    If Me.OpenArgs & "" <> "" Then Me.RecordSource = Me.OpenArgs
End Sub
