Hi all,

Right now I'm programming a device to interact with my program VB.Net 2008. Btw, the driver is provided and installed. Using the provided .dll, I cannot add a references in VB and also register the .dll in system32 which return error "not a valid assembly or COM component". Why? Any other option to use the DLL?

Also, from the title above, how can I send command through USB port same as using serial port? Because this supplied program has a test program and have log each command send to the device. It convert hex to ascii character. So how to use this? Any link to provide the best solution?

You need to go back to the people who provided the dll and ask them for help.

You left out the most important piece of information. What device is this?
