requires install of OpenNETCF ??

[MikeB]

I just installed my cf app onto a device (it runs from the emulator), I
installed first all of the required cabs including
OpenNetCF.sdf.ppc3.armv4.cab, and after my app gets installed the following
message is displayed:

<myappname> requires the installation of OpenNETCF.SDF.ppc3.ARMV4.CAB for it
to run properly. Intall the Cab file before running this application.

I did install it, and it displays in the Remove Programs applet.

I've installed this many times before without a hitch. I have also cold
booted the device and cleared the registry. Still, same thing. Help??

Could this be because two different machines have two different versions of
OpenNetCF? I made code changes at my dev pc and just moved the app's cab to
another dev pc. Installed opennetcf and the app from there. Found that if
I installed a copy of the app's cab that was built on that PC -the program
runs fine and doesn't get the warning message that OPENnetCF doesn't exist,

How can one tell what verions of OpenNetCF is installed on a given PC?
And, how can I tell from the OpenNetCF cab file what version it is?

The cab files are not named with a version but you can check the date and
size, v1.3 is larger and created on the 12th May

Thanks Peter - I just found that too.

What appears to have been our problem was that the PC I was installing from
still had the OpenNetCF v1.1 cab, my development machine has OpenNetCF v1.2.

It seems that an app built with OpenNetCF v1.2, is not compatible with a
device running OpenNetCF v1.1. Expected now that I know whats going on, but
hard to tell from the message. Good to know for future reference.

I've now installed v1.3 on each of my dev machines. Now, I just realized, I
have to remember to send out the new OpenNetCF cab for other apps I have
'out there' when I release an update.

Good to know.

If I'm missing something however, please let me know.

Thanks again.

Please note that if you use v1.3 and you use the OpenNETCF.WindowsCE.Forms
assembly you'll need to workaround a known deployment bug in this release:-

Please help me here - its getting late and I have an 8am demo where I plan
to run the emulator to show this app. Ever since trying to update to
OpenNetCF v1.3 I had problems. I uninstalled and reinstalled v1.2 - but now
am getting errors when trying to run the app in the emulator:

An unhandled exception of type 'system.missingmethodexception' occurred in
system.windows.forms.dll

There are a few others that pop up following this one.

What can I do?? Is this caused by the v1.3 install???
