Developing things like this is a real time eater, it took five hours yesterday to learn about and start playing with Dundas charts, then they run slow

I would use my own graphics like I do on the Pocket PC and it scrolls nicely, but the same code doesn't work to scroll on the PC, and I can't work out why. I can run the actual Pocket PC application on the PC, and everything works except my scrolling.

The xml would be an amalgation of the individual xml files I put in with each ROM distribution - it would contain the addresses and sizes of each map that would be live edited.

Ok so the ones in the zip should be a good starting point. Basically though you would move the UI out from the autogenerated section of the code it is in today and create it on the fly. Its not that hard for that part...the autogen'd code that the designer gives you today is pretty much what you'd write except taking in variables that were parsed in your xml. The harder part would be figuring out the general algo...will take a more in depth look to figure it out.

Thanks.

I managed to get my own bitmap scrolling working. On the PocketPC you can do a graphics.drawimage with the source and destination bitmaps the same. On the PC you need to buffer the bitmap by copying it somewhere else. I think it should give good flicker free scrolling.

I also tried just throwing random values at a Dundas chart without actually logging on a 1.6GHz dual core laptop, and it is much slower than my own code on a 206MHz Pocket PC. So I don't think we'll rush to multithreading for now, just get the simple but fast and smooth bitmap scrolling on the PC.

has anyone else been modifying the source code, specifically getting 1 xml with all data for an ecu. now that i got charting working etc the next issue was to modify the code to use no hardcoded values. and then 1 xml with all map info... but no point doing it if someone else is doing/done already... i am not a good coder as well
