Error: run time 8018
Hi all.
I am working on the programming about the microcontroller and the vb using serial port. The problem is when I use the program in my PC, it works.
But, after I run the program on the other pc, it did not work and got an error which is:
run time 8018
operation valid only when the port is open
Thanks in advance.

Re: Error: run time 8018
That's usually caused by something else using the port, so your program threw an error (which you told it to ignore) when it tried to open the port.

need help
tq for the reply..actually there is not any device used at that serial port except my device..and i have something weird using the port which is when i just insert the DB 9 cable into the PC serial port the LED from my external circuit has flashed..that's mean the signal has been sent eventhough i did not sent the data from my program..
how can i overcome this problem..tq..

Re: Error: run time 8018
Which means that some program is using that port.
Check for things like a Palm or PocketPC link program - even if the external computer isn't connected, those programs keep control of the port.
