    Re: run java with your project?

    You can always put a pause command as the last line of the batch file. The CMD window will then remain open until you press a key. This will give you time to see the result of the previous command.

    Re: subscript out of range error.

    It would be helpful to have the client code to see how you are handling data from the server.

    You could use the SMTP protocol. Here is a wiki on SMTP.

    That will turn RM00 0AA into RM000AA or Some Town into SomeTown.

    You should be able to copy a UDT with CopyMemory with no problems. I do it in many of my apps. How are you coding the statement? And the structure(s) involved?

    There are several problems with your converted code.

    Dim arrNames(20) as String actually creates an array of 21 (0 to 20) BSTRs, not strings. A BSTR is a 4-byte 'pointer' to a string that is...

    Well, for one thing, you are closing the connection after doing the send and the data most likely (in fact I would bet on it) has not finished being sent.
