A quick follow up comment to wrap up the thread.
To get a runtime view on the PC of 240 x 320 I need to set the screen size in the PC Designer to 243 x 313 on XP and 251 x 322 on Vista. The Designer on the device is fine of course as that is running on the target.
Changing the screen size in the PC Designer is only a workaround and not a fix as this changes the form size in the Designer. Although the runtime size is now correct on the PC, and will match the device, those runtime views (and Design time view on the device) doesn't quite match that in the PC Designer. The width in Vista and the height in XP are quite a lot off.
Although I bought B4PPC to actually develop on the device I actually intend to do the layout and initial coding on the PC and refine on the device so matching the Designer view to the device is quite important (to me anyway
)
Please don't these comments as criticism. I like B4PPC and it lets me work on the device and in a .NET sort of way that looks something like Visual Studio. I've found nothing else to match it. In some ways it is better than VS for small jobs being quick and easy to use. I think that it has potential for further improvements (but still has some rough edges!)
