Hi all,

My customer reported an issue today with merging dw's and pdf's.  In the main window, he opens a salesorder with 100 workorders, then selects the Merge Each radio button and clicks Merge on the toolbar.  The merge function loops through each workorder and merges the associated documents then saves.  wf_merge_each loops through, calling wf_merge_one on each pass.  Customer said if he does something else, like open Word or Excel, while he's waiting, wf_merge_each doesn't merge all 100 workorders.  

Here's the code for the two windows functions:

//wf_merge_each
integer li_CertCount, li_ThisCert, li_x, li_rc

//Loop through all of the Certs in the ddlb
li_CertCount = ddlb_certs.TotalItems()
for li_x = 1 to li_CertCount
	ddlb_certs.SelectItem(li_x)
	ddlb_certs.Event SelectionChanged(li_x)
	li_rc = wf_merge_one()
	if li_rc = -1 then
		return
	end if
next

//wf_merge_one
PDFDocument lpdf_doc
string ls_docName, ls_filename, ls_docDir
long ll_rowcount, ll_thisrow, ll_attachmentCount, ll_thisAttachment, ll_rc

ib_cancel = FALSE
lpdf_doc = Create PDFDocument

//Add Cert to PDF and/or Maintenance Record to pdf
if dw_1.RowCount() > 0 then
	ll_rc = lpdf_doc.importdatawindow( dw_1)
end if

if cbx_maintenance.checked then
	if dw_2.RowCount() > 0 then
		ll_rc = lpdf_doc.importdatawindow( dw_2 )
	end if
end if

// Add attachments
ll_attachmentCount = dw_attachments.Retrieve(il_WorkOrder)
ls_fileName = is_pdfSO + "Cert" + string(il_workorder) + ".pdf"
if ll_attachmentCount > 0 then
	ls_docDir = is_docDir + string(il_workorder) + '\'
	for ll_thisAttachment = 1 to ll_attachmentCount
		ls_docName = ls_docDir + dw_attachments.GetItemString(ll_ThisAttachment, "filename")
		// Check to see if document exists
		if FileExists(ls_docname) then
			ll_rc = lpdf_doc.importpdf( ls_docName )
		else
			ll_rc =MessageBox("Merge Documents", "The following attachment does not exist:~r~n" + ls_docname + "~r~nContinue?", Question!, YesNo!)
			if ll_rc = 2 then
				destroy lpdf_doc
				RETURN -1
			end if
		end if
	next
end if

ll_rc = lpdf_doc.save( ls_filename )
if ll_rc < 0 then
	MessageBox("Save Error", "An error occurred saving the merged PDF file.~r~nError: " + string(ll_rc), StopSign!)
end if

destroy lpdf_doc

return 1

It works fine if he does not do something else in the meantime.  Any advice?
