View 2 RepliesUnable To Close Serial Port After USB / Serial Converter Disconnected
Mar 28, 2006I have a stand alone VB.Net 2005 application that uses a serial port that generally stays open while the application runs on a Windows XP system. In trying to bullet-proof the UI, I ran into a problem when the USB to Serial Converter normally used to provide the serial port is disconnected while the serial port is open. In trying to handle the resulting error when accessing the port, I find I cannot close the port.
When trying to do so, the error message says something like "unable to close the port. You may not have sufficient permissions." Reconnecting the USB/Serial Converter does not reactivate the port.

Serial Key With Database?
May 9, 2010I have built a application and I want to deploy it using a serial key so I want to make it so that it checks the the database keys before activating and if possible to check for correct data every time it loads (the last part I can do it myself if I can get the main part done) so when the app loads it will activate it by checking if correct serial is introduced and comparing it to the database values the database should be on a server (web server) and powered by MySQL?

View 14 RepliesCommunication Via Serial To USB Cable
Jun 24, 2009I have a device that communicates with the pc via a serial to usb cable. So I have made windows form with a serial communication to speak with it. The communication is every 125ms so every time it checks if the com port is open and sends the new message. The problem is that if the usb is not connected the program tries every 125 ms to connect to the serial port and the busy cursor appears always and the form is not responding to any action (for example enter into the menu or refresh a listbox). I have tried multiple times to connect and disconnect the usb while the program is running. That's mean that the serial connection stopped and started all over again several time. The problem is that occasionally it shows an error "unable to open com port".
