test if jpg file exists in other domino database

Question

I'd like to make a fallback when displaying pictures out of a notes database. The notes database normally contains a pdf and a jpg version with the same name (except the extension) If the jpg picture exists I would like to display it , if not I would like to display the pdf using google drive

return "<embed src='https://drive.google.com/viewerng/viewer?embedded=true&url=https://demourl.pdf' width='500' height='375'></embed>"

So the question is : what's the best way to test if a picture exists in a notes document

Answer 1

You can create a view showing all design elements and then do a lookup if the required picture is contained in the database.

Here is the required Lotus Script Code to modify a view for displaying all design elements in a NSF:

Dim session As New NotesSession
Dim db As NotesDatabase
Dim view As NotesView
Dim doc As NotesDocument

Set db = session.CurrentDatabase
Set view = db.GetView("DesignElements")
Set doc = db.GetDocumentByUNID(view.UniversalID)
Call doc.ReplaceItemValue("$FormulaClass","32766")
Call doc.Save(True,True)

Just add a sorted column for "$TITLE".

EDIT 2: If you just want to check for a existence of a file in a normal document, I suggest to create a view with two sorted columns. 1st column with DocumentUNID, 2nd with @AttachmentNames-Formula. Then you can do a lookup for the specific document / attachment.
