Hi all.

I have a need to collect COM data on a WM5 device and 'throw' the data at
the current cursor, regardless of application or field position. Anyone
have a sample or a head start?

I know there are data wedge utils for bar codes scanners, but this is data
direct from a com port and I need to interrogate it first.

I'm ok with the com port code and I'm already capturing the data without
problems.

Thanks.
 
You can use keybd_event (P/Invoke from Managed code) to place characters in
the keyboard input. e.g.

[DllImport("coredll.dll")]
private static extern void keybd_event(byte vk, byte scan, int flags, int
extraInfo);

This looks like what I need, although a thorough search has only pulled up a
couple of examples for VB2003 PC code. I need something for the CF, WM5.

If someone could kindly show an example of how to send a single character to
the cursor, in VB Net CF, for WM5 I'd be fine from there.

Many thanks.

keybd_event() doesn't exist on the PC, so any example you found was for
Windows CE. Use it.

}

and

string tekst = "ZWYKLYKODEAN13";

foreach (byte znak in tekst)
{
SendKey(znak);
}
 
Many thanks.

The data coming in is all basic keyboard data, so in the end I had to create
a char array and convert this to a byte array and send the data one chr at a
time. But I've got it working great now.

Thanks for everyone's input.
Very much appreciated.
