Serial port receive buffer overflow error

[vindsan]

I am trying to send a file from one folder in my computer to another folder in computer using tcpip conncections as part of me learning labview. But I am getting an error 

Possible reason(s):

LabVIEW: Serial port receive buffer overflow.
=========================
LabVIEW: The network connection was refused by the server.

I dont know how to fix that. So Please help me. I have attached the VI here. Thanking You,

You probably want to have your Server code inside of a loop.  The client code would be the one to not have in a loop.

I would also recommend having a timeout for your TCP Listen and use a state machine.  This will allow you to cleanly stop your code instead of using the Abort.

Thank You. The error is no longer coming, but it seems the file is not being copied properly. In the target folder it is showing a file with just 1kb and not the file I sent and i cant open this file as well. So please tell me what to do. Thanking You.

You are just reading 1 character from the file.  With your file read, set the count to -1 to read the entire file.

Also, for the file write, there is a boolean input on the top for "Prepend String/Array Size".  Set that to FALSE or you will get some extra data at the beginning of your file that you will not want.

Thank You very much I got it. No more error and I am able to copy. Thanks a lot. Next step is try and copy to another computer. I will ask doubts when I have problem with that. Thanks a lot for your help on this one.
