Hi, I am working on a control application that uses a few ICS components. One of this application options is firmware update to embedded device over TCP.
I have created a form that has one TWSocket, a few timers, progress bar etc In general the user chooses a file to download to the device and clicks a button to start the process. This form is created dynamically, it creates the socket and all. The application can open as many forms as the user needs. Every form has its own state machine and its own buffer , socket etc The update worked fine for a single device and even for 2-3 concurrent updates. For some reason when I triad running more then 4 forms, sometimes the application crashed completely, sometimes one of the forms stopped the file transfer and timed out. After making a few changes I am now stacked with a Stack Overflow exception and no matter what I do I cannot run even one form. The stack overflow is inside the TWSocket. I am sending a 4K bye buffer and then in the DataSent event I send another one and another one Actually the stack overflow happened when I triad to send smaller buffers (1K) now even after returning to the previous code with 4K buffer I still get the stack overflow. I am using XE4 with C++ Any ideas or suggestions would be appreciated. BR, Noam. ************************************************************************************ This footnote confirms that this email message has been scanned by PineApp Mail-SeCure for the presence of malicious code, vandals & computer viruses. ************************************************************************************ -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
