Im working on a simple Job Completion email web app. The app allows the user to enter specific information, creates an email and sends it off. The issue that im having is how to allow the user to attach a pdf file to the email. I can’t figure out how to get the webpage to open a file explorer for the user to choose a file and attach it to the email that will be sent out. Ive looked at web file uploader control but I don’t want it to save to the server, I would prefer to keep it in memory and then gets removed once the session closes. Am I overlooking something super obvious?
