Hi,

I have a PDA with Windows Mobile 5.0 OS. In the application, there is
a feature to auto upgrade the application if a newer version of the
application is available on the server. The application actually
downloads the newer version and then after a restart, the application
explodes the new cab which is downloaded. As per my knowledge, Windows
Mobile 5.0 uninstalls the previous version of the application before
installing it again. I am facing the issue where the previous version
of the application is not uninstalled completely whereas the newer
version of the application is also not installed completely.

The process for auto upgrading works fine for most of the times but
sometimes it fails. Is there a way I can overcome this?

Thanks,
Kshama

The best way is to do a soft-reset before attempting any upgrade.
WM6 has fixed many of these problems where you get partial
uninstalls, but unfortunately, WM5 is still a bit of a pain to
get it to upgrade apps.

If the soft reset doesn't work, uninstall the app manually, then,
if it fails, soft reset and manually remove the application's
folder in Program Files or on your storage card, then make sure
no shortcuts exist in \Windows\Start Menu. You might also look
for traces of the app in \Windows itself, but be careful.

THen, for good measure, soft reset again and start the install of
the new app.

Hi,

Thanks for the response. Also, I would like to know if it is possible
to perform a soft reset of the PDA from the application itself. My
application is built with .NET CF 1.0 using C# language.

Thanks,

I know there is as there are "soft reset" apps out there. You
should ask that in the .developer group.
