Bulk Copy inserting each row twice

Now i got it to work but the bulk copy is inserting the rows twice, instead of once

and i know the table has the correct rows because i can see it in the gridview correctly

I FIXED THIS PART

my program works fine when i run it in debug mode but not when i place it on the server, it doesnt run the stored procedure when i put it on my server.

Are you using the same DB server for both? (That is, is your connection string actually hard-coded, or did you modify it for simplicity's sake?)

If the server does not have mixed mode authentication turned on, you will not be able to connect with a username and password.

UPDATE:

As @santiagoIT mentioned, if you put exception handling around this and log the exception that is being generated, you will most likely see very quickly what is going wrong.

EDIT:

Per the request in the comments, here is how to implement exception handling with (rudimentary) logging:

Try
    'Your block of code
Catch ex As Exception
    System.IO.File.WriteAllText("MyLogFile.log", ex.ToString())
End Try

As mentioned by @santiagoIT, various logging frameworks exist to make logging more robust and stable (what I have done, for example, will throw an exception of its own if the log file is already open elsewhere). I would recommend something like this for a real solution, but what I have shown will help you debug the issue at hand.

I recommend that you install ELMAH. It is trivial to add but will give you HUGE benefits. It is an error logging framework. Once installed look up in the ELMAH error log and see the exception details. It is most certainly database related and the error log will should give you enough info to know what the problem is.
