Afternoon all

Why's that then?

My first guess would be that the real-time version isn't setting the AutoRedraw property (or whatever it was called) to True...

You should probably set that in the Properties sheet (or whatever it's called) at design time, rather than having to remember to set it at run time.

Although of course that's just another of MS's leaky abstractions... IIRC, setting a property at design time merely generates a line in the boilerplate initialisation code that sets it at run time before your own code runs

Ho hum

It transpires, after reading one of my 4 inch thick VB3 tomes that if you make autoredraw true, it waits for the whole thing to appear on the bitmap before it paints it... however by minimising & maximising the window, you can get it to paint.

I added another form with a picture, which has autoredraw true, while the original form.picture has autoredraw false.

And lo, with it false, it paints line by line, whereas with it true it waits for the end of the screen to be reached.

When I save the image (as discussed previously), the image saves successfully, but the comms buffer overflows & comms grinds to a halt until I close & reopen the port.

This stuff is so much fun...

I suspect its because I'm using VB for something it's not designed for.

Pretty usual for me, really.

Why is it that whenever I make a techy post it goes all quiet?

It's eerily like a real-world conversation

I've given up conversations like that; no one knows what the feck I'm talking about most of the time.

We're moving - sold the house (fingers crossed it all goes through) going to rent for a while and bank the all the filthy lucre

Don't forget the £35k per account thing...

Hey Chimp!

I was just going through some old boxes and found a photocopied data sheet for an 8250 UART

That was from a long time ago!

I've still got a National Semiconductors databook with that datasheet in...

I snuck off 10 mins early this afternoon to catch the posh train home... that aircon is addictive in this weather.

Have you thought about caching the data as it arrives, whilst also drawing it line by line, then when it's time to save, create a new bitmap thingy, draw to that using the cached data, and save that?

Or have you already tried that?

Ah twat, I spelt it wrong..... knew it looked silly!

It could have been worse! you could have said cockoo!

[BrilloPad]

hi everyone... thought I'd just look into to say hi and take a break from packing!

hi!
