RE: VB 2005 express

["Dave Sussman" <davids@xxxxxxxxx>]

I'm not a winform developer so probably can't help much. However, I do
know that you can only update the UI from the UI thread, so it sounds
like you've got a background thread doing the monitoring. If so, you
need to use delegates or the BackgroundWorker component, to marshal the
data to be displayed to the UI. Unfortunately I know nothing about how
to actually implement this, but a quick google should help point you in
the right direction.

Hi Guys,



Anyone here using VB 2005, I'm rather new to this. I used
vb6 to build 2 apps which monitor the pins on a serial port to record
the flashes from my electric meter. However due to a hard disk failure I
have lost vb6 and all the code I wrote. So I have download vb 2005
express and am trying to get this to do the same as I now have a water
meter which will pulse for each litre. I could do with some help as this
is a very basic app but I get an error which I don't under stand.



With in the event trigger by a pin changing on the serial port should
update a text box on the form, but I get and error saying I can't do
this as the thread is not the one the form was created by. Can anyone
shed some light on this.



I can send over the code it that would help.





Regards,



Paul
