Read rfid card information in visual studio without button Member Apr Member Hello, I want ask that, how can I read rfid card information in visual studio without a button option? I mean we can read the card ID in Arduino program and then we connect aduino with visual studio.
Then read the card and see the information on the display. I would be very pleased if you can help me. Thank you. None; sPort. One; sPort. ReadExisting ; MessageBox. Show StrRecieve ; this. Connect and share knowledge within a single location that is structured and easy to search. I've got a clarification question regarding the receiving of data from across a serial port from an Arduino. I know the communication and code running on the Arduino works because I have tried using the Serial Monitoring tool in the Arduino IDE and am able to send and receive the appropriate responses.
It's a very simple event handler that is assigned to the DataReceived event of my SerialPort object that is part of my form. I've set a breakpoint inside of it, and it never gets triggered. I'm kind of at a loss, I've done a nonexistent amount of work with Arduino or hardware so I'm not entirely sure what my options are for debugging. If anyone has any debugging suggestions or ideas what I'm doing wrong I would very much appreciate it.
Additionally, if I haven't provided any information let me know what is needed and I'll edit it in! Perhaps one or all of these will be what ends up fixing it. In my case, only DTREnabled needed to be true. I don't quite understand what these settings do, but there you have it. It will appear at the bottom. I also did same mistake. Now corrected it. But facing another problem… Com port sends data led on usb converter blinked but is not received on hyperterminal..
Also from other side if i send some data then vb application is not receiving data. Thank you very much! I will use you code for base to create a new one. Good work! Hi, my name is Laurentiu and just joined the site today.
I am also interested to obtain the above code. I have sent the email on the provided email ID …. Kindly follow the instructions in the mail. Could this be computer related? Before running the project …. No change. Will it detect virtual serial ports via usb when there is no actual serial port on the computer? Yeah it will detect that usb port …. I think you are using serial to usb converter …. The best way to test the software is via virtual port …. I need it urgently.
Kindly subscribe to us and the files will emailed to you …. Can i ask something. I already follow all your instructions. I can debug the code. It is because i used virtual serial port? Add a comment.

Mitch Mitch I was able to get it working through a combination of your suggestion and the one in the comments, thanks for the help — jalconvolvon.
