Users have been entering information into a database running in Lotus Notes for some time, and now they would like to attach documents to it. All this time, I've been mostly clueless as to how to do it, reading somewhere that it only works when viewed through the web browser, and then giving up for a while.
But to allow users to upload/attach files to your form, just create a rich text field... thats it.
I was pretty amazed at the simplicity of that. Nothing tricky. Just to not keep secrets, I additionally changed a setting on the control tab of field properties, under storage, I set it to "Store contents as HTML and MIME", just for possible future compatibility.
