I am not sure if the BLOB data is being pulled or not. I am having a problem inserting it. The MSDN help is a little lacking on the subject. I am storing the data in a datatable. The information is then compared to a second database. If the second is differant than the first, a row is either added or edited. Replication can't work due to the internet factor.
Basicly I am looking for the best way to pull the data and store it. I'm not too worried about the internet portion. I believe that is working fine.
I have increased the point value.
I went to look around for you, found a rather excellent site that gives the complete source code to storing / retrieving/ viewing BLOB using SQL. I did a quick overview of it, and it seems pretty complete. Here's the site

Please tell us if this is what you have in mind...
You want to write a program in .NET that would grab the BLOB data image from a table in SQL Server. You'd probably want to use SQL DataAdapter.
Then, after you got the BLOB data image, you want to initiate a UDP/TCPIP procedure that would connect with the remote computer that's listening with a server program. When confirmation is recieved from the remote server, the connection would be formed and the transfer would begin.
When the transfer is completely over the protocol, you want the remote server to initiate a function that would connect to its local SQL server, and start a stored procedure that would store the BLOB data image in the table specified. Then, it would resume to listening mode again for any other incoming connection.
Am I close to what you are thinking about?
