input panel error on emulator

Milsnips · Jul 5, 2005

hi there,

i have an application i created, and i added the inputPanel control to the
form. when the user moves focus around the form, i set the
enabled=true/false accordingly, which all works fine when testing on the
pda, but the same code on the emulator crashes with an exception in the
following scenario:

PocketPC2002 Emulator

form is open, and the inputpanel is displaying
menuitem1 - has the code "me.close", when this is clicked it crashes.

Can anyone else confirm this or is it some bug in the emulator doing this?

thanks,

Install SP3 and if you are still having problems post back with full sample
code. How to detect version and where to get each is detailed here:

Hi Daniel,

i installed the CF.NET sp3, and the problem still occurs which leads me to
believe it is a bug.

CF.NET Version installed on emulator is :

this is the code that causes the problem....

Is it WindowsCE 4.1 emulator that comes with VS.NET? If so, it doesn't
support InputPanel.

Milsnips · Jul 7, 2005

yep it says Emulator version 4.1.0 (build 14)

the inputpanel works fine in the emulator, its only when i close down the
form it returns this error.

thanks,
Paul

Um... what is the title of the emulator window. It's "PocketPC 200x",
isn't it?

Nevermind, just tested your code with PocketPC 2002, PocketPC 2003
emulators and it works normally. Follow Daniel's suggestion how to
detect that your emulator has the SP3.
