Exporting Multiple MS Access Forms to A Single PDF File - ms-access

Question

I'm trying to output multiple forms to a pdf file with the following code in Access:
Public Function Print_Form()
Dim myPath, reportName As String
For Each r In gvParent_Vals
glParent_id = r
If giMsgBox = 1 Then
//this method opens the form and makes it the active object
Select_Form
//set file path and pdf file to send form to
myPath = "C:\Users\C062342\Desktop\"
reportName = "test.pdf"
//output page 1 of the form
DoCmd.OutputTo acOutputForm, "Frm_Main_Report", acFormatPDF, myPath & reportName, False
// set global variable to page 2 source form and specify target to replace (subform of page 1 form)
gsActiveForm = "Frm_Main_Report_Pg2"
Set goCurrForm = Forms![Frm_Main_Report].Form.[Frm_Main_Report_Pg1]
//method to set the page 2 form by setting the target equal to the new source object
Activate_Form
//send page 2 to the same pdf file
DoCmd.OutputTo acOutputForm, "Frm_Main_Report", acFormatPDF, myPath & reportName, False
//method to Close the form
Close_Form
End If
Next r
End Function
When I do this in a loop I only get the very last form that opens, as if when Access is sending each form to the PDF file it is overwriting the last one each time. The other problem is that I need to output the form in landscape and I'm not sure how get this to happen in the PDF file. Are there any settings that go with this method or code that would precede or follow it that would allow me to accomplish this?

Answer 1

What you are trying is not possible. Access cannot append to an existing PDF.
DoCmd.OutputTo with an existing PDF file will overwrite that file.
The best course of action is to create a report that contains all data you want to export.
Or: use an external PDF printer driver that has multi-document capabilities, i.e. you create several print jobs from Access, and the driver combines them into one PDF file.

But this will a manual operation, unless you find a driver that can be fully automated.
