Excellent work delivered. Top class developer that understood exactly what needed to be done and resolved the issues I was encountering. Will definitely be using again of future projects.

Description

Specification

I have working MT4 and MT5 example program code using pipes via importing kernell32.dll in MT5 to receive transactional messages sent from another MT4 instance running.

Most of the time it works fine. But intermittently I get an ‘Access violation’ error generated showing in the Experts tab of MT5. It fails to read the message sent from MT4 and does not trap the error. Also, when I try it on a different VPS computer - the same code that works on one computer will not work on the other. Even when it is sending exactly the same transactional message from MT4 to MT5 one fails and the other works!

I need someone to review the code and fix whatever is causing the issues. I suspect it is something to do with the #import declarations that is causing this. Or possibly, occasionally when MT5 tries to receive the messages send from MT4 there is a timing issue and they have not been fully written to the pipe. I’m only making suggestions here as I have been unable to fix the issue.

MT5 uses #import kernel32.dll to create and opens the pipe and acts as a server. It uses ReadFile to retrieve the transaction data sent from MT4.

MT4 connects successfully to the named pipe opened in MT5, using FileOpen. Then uses FileWriteInteger and FileWriteString after to send the data to MT5 fro reading and processing.

My example code has examples of sending Integer values and String values from MT4 to MT5. Once the issues have been sorted, I would like to be able to send a Double type value too.

I will provide all the short MT4 and MT5 test programs that do all the above for review. The project job is to correct whatever the issue is with the intermittent issues and make them generally more resilient and robust. Also, not sure if it is possible, but can MT5 send a confirmation message back to MT4 to say that a transaction has been received and processed correctly?
