1) Add a new record - I can currently add records text to access database, but not images.
2) Get the ID [URL]I'm not sure how to integrate this code into my code. I am stuck here.
3) Save the image in the filesystem using the ID as a filename - I can save the upload an image and save the image to a directory on my computer, but I am unable to name the image that of the ID of the access database.
4) Update the database to put the filename in the record you just created. - I am unable to do this as well (obviously).

Dim dateToDisplay As DateTime = DateTime.Now dsNewRow.Item("date_created") = dateToDisplay.ToString("MM.dd.yyyy hh:mm:ss tt")
I tried stepping into the code by debugging and it seems to be inserting the PM but is not displayed in the table QuotedateToDisplay#8/12/2011 6:01:06 PM#Date
