vb 6 and vnc
I have created a user control which communicates to a com port using the mscomm control. In my main program I have an instance of this control, which accepts information from the main program as well as sends/receives/parses information from the mscomm control. Periodically the user control seems to lock up. I can no longer send data from my main program to the user control. The user control no longer accepts data from the mscomm control. If I exit out of the main program and restart, it will work for a while and then the same will happen. If I reboot the computer all works well. This seems to happen after I use VNC to connect to the computer running the program. Is there any known issues with VNC/VB6/MSCOMM?
Thanks
Thanks
it might be the VNC hook

it hoks one of the ports to control input\output

So is there a way to get around this problem? Have you heard of anything like this before?
what port are you using in vb?

I see there is a new version of VNC. I'm going to first install that and see what happens.
Could you explain your workaround to me. Do you have any sample code?

I'm using COM Port 1 to send/receive data via MSCOMM Control.

My VB Ap does not freeze up. I can still do things, the part that freezes it my user control. I can no longer send data from my main program, or receive data from MSCOMM Control. However I can still type or do whatever in the main program.
