Differences between Virtual and Real FP

Hello,

The Virtual Flexpendant is in general a great tool that helps a lot to debug and test Flexpendant applications. However, it sometimes behaves in a different way form the Real Flexpendant, which can be quite confusing.

I have found few differences:

1 - Fonts: In the VFP fonts are appear by default in a nice 12 bold format, so:

a) it is not of much use to help the developer to check if all fonts have been assigned.

b) it can mask other problems. We had a hard time trying to find out why an application that worked perfectly on the VFP, showed an empty screen on the real FP. The reason was this piece of code:

System.Windows.Forms.Panel pnl;

pnl.Font = TpsFont.Font12b;

Using the "Font" property of a panel generates an unhandled exception (of the type NotSupportedException), which is a bug of the Compact Framework, but the fact that everything appears to be OK in the VFP is quite misleading !!

2 -  Textboxes: The event click is ignored on the real FP, wereas it works just fine on the VFP.

Is there a reason why these differences should exist? Or will they be fixed?

Are there any other known differences that developers should be aware of?

Regards.
