Here is the code:

Datagridview As An Input Device

Apr 14, 2009

Is it possible to use a datgridview as an input device and then transfer the input to variables (one or two dimensional). I am creating a programme that can be used for a widely divergent number if inputs and the grid would be easier for the user rather than me creating a lot of text boxes at design time which may not be required much of the time and a datagridview would probably be preferable.

Detect When A New Usb-device Is Connected?

I found this thread: [URL]

I know the solution is in here, but I'm overlooking it I'm afraid. What I want:

Get Custom Data From USB HID Device?

Aug 4, 2010

I've created a custom USB device using a PIC18F4550 and I'm having trouble with reading information from the device. The device sends reports without a request from the application as 64 bytes. I'm relatively new to VB and this is my first foray into USB as well... It's not going good. I've set the Vendor ID to Hex 1234 and the Hardware ID to Hex 0001. I've used different libraries and the timer to check for incoming reports, but I can't seem to figure it out. I've waded through pages of USB Complete and all kinds of code for mice and barcode scanners, but nothing so far that will do anything for my device.. how I can register the device and get the raw report from the device and display it in a text box
