Hello,

I've gotten to the point in my PocketPC app where I'm trying to delete items
from GCal when checking shows that the appointment was deleted from the
PocketPC.

On http://code.google.com/apis/gdata/client-cs.html it says to just do "
entryUpdate.Delete()", so I tried that, and it throws a
NullReferenceException:

System.NullReferenceException was unhandled
  Message="NullReferenceException"
  StackTrace:
    at System.Net.HttpWebRequest.startSending()
    at System.Net.HttpWebRequest.startReceiving()
    at System.Net.Connection.startReceiving()
    at WorkItem.doWork()
    at System.Threading.Timer.ring()

And then, when I clicked away the VS2K5 debugger's exception pop up, a
dialog box came up saying "No symbols are loaded for any call stack frame.
The source code cannot be displayed." Normally, when you try to continue in
VS2K5 after an unhandled exception it just bumps you back up a level in the
call stack and re-alerts you to the unhandled exception, but not after this.
I had to end the debugging session as the VS2K5 debugger could not continue,
though it didn't crash VS2K5.

I tried using the CalendarService object's Delete() method, but that did
exactly the same thing. :-(

Anybody know what is causing this or how I can get past it?

Development environment is Visual Studio 2005 Pro on WinXP, and this is a
C#/.NET application for Windows Mobile PocketPC 2003 edition. The mobile
unit is a Dell Axim x50v running Windows Mobile PocketPC 2003SE, with the
A05 ROM update from Dell.

The code which throws the exception is basically the bits from the
Calendar.c sample in RefreshFeed() that iterates through all entries in a
specific feed, with my inner-most loop determining what synchronization
action needs to be done (save, update here or there, delete, etc...). The
EventEntry object is not modified before entry.Delete() is called, though
entry.Id.AbsoluteUri is accessed to look up the correlation to the local
PocketOutlook item OID.

Please let me know if seeing my code will help.

Thanks in advance for any help.
