1) You can't add the combo to the grid itself, but you can try this
2) To automatically send a file from one machine to another is a little more sticky.
- If you were going to send the file from one machine to another on the same network you would simply need to create a share on the receiving machine so that the application pushing the file on the sending machine has permissions to write to it. I personally would prefer it the other way around where the destination machine pulls the file from a share on the sender instead.
- If you are going to attempt to push the file from the sender over the internet to a server, then you'll need to provide some form of sending interface that will reside on the sender and then an interface on the server that can accept the file and write it to disk. I would suggest looking into web services for the receiving server and a windows service or an application running with a Windows Task Scheduler profile that can hit the web service.
