Private Const VendorID = 6017
Private Const ProductID = 2000

Check to make sure the vendor & product ID numbers in your VB source match the vendor/product ID #'s in the PIC framework files generated by EasyHID. If these don't match, the VB app will never respond.

Although i have changed the ProductID from 2000 to 2005, the device is recognised.

The VB program displays a text box which says USB Device Connected or indeed Disconnected, depending on its status.

So, i think this bit is OK.

What exactly is happening? Are you getting nothing on the label caption? Have you verified your hardware with something simple like reading the A/D input, and displaying the result on an LCD, serial terminal, etc?

Basically i'm putting 5v on the PORTA.0 pin and just gettin 'label1' in the label of VB.

Should VB always be updating and looking at the USBinput or should there be a READ button thats calls the procedure?

Also on the VB side it has:

MyText = (CStr(BufferIn(1)) + Chr$(BufferIn(2)) + CStr(BufferIn(3)) + CStr(BufferIn(4)) + CStr(BufferIn(5)) + "V")

Most of it contains CStr but the bit thats contains Chr$, i presume thats for the "." as sent from the PIC.

I've tried playing around with it, but still no joy. If you have it, is it worth sending me the vb source file you have just for this bit?

Are you on messenger, i am, i thought it might be easier to converse?

Thanks again,

Steve
