Looping through visible cells for excel to access insert - excel

Question

I have a project I am working on where my team uses an excel front end to manipulate the data which in turn updates an access database back-end to hold the database. (there are good reasons for this)
The current version works by if a user changes data in a cell and wants to update the database they highlight the cell(s) and hit an update button. (this becomes annoying doing multiple updates). So I started playing with the worksheet_changed function.
In order for the worksheet_changed function to work the user has to move off of the 'updated' cell in order for excel to notice the change and update the code. (In my case hitting enter or down arrow after data entry). I have gotten this to work well using the offset property to look at the row above and enter that line into the database - however - when the spreadsheet is filtered as it always is...if the row above happens to be hidden it will update that row when actually I need the visible cell to update....so I am stuck - below is a small chunk of the code used to update the database.

Any help is GREATLY appreciated - thank you

Answer 1

Target.address
this should reference the cell address of the changed cell, so unless you change a hidden cell a hidden cell should not be referenced
if you just need the row you should be able to do Target.Row
