Perhaps little background will help as I can't post an image of the form. I have an RFID reader which connects to the computer via a usb. The sample app from the supplier (the c# Code). Just provides a list of available devices in a combobox after clicking the refresh button. This all works in my VB code as well and after clicking the button it shows a list of (COM1 and COM5 on my laptop) in the combobox. After selecting the correct COM from the dropdown (COM5 in my case). You then click the connect button and it is at this point that my VB code falls over, but the C# code works fine. The form is very simple, I have compared the designer code and nothing different there either. I'm just very confused as to why the VB code gives the null exception but the C# code doesn't. Yet the code is almost identical.

The writelog is just a list box which provides a log of all the steps taken and events which are initiated by the reader.

Hope this helps

Regards
Shane
