what's the difference between wm6 and wm5 apart from adding html format in wm6? use the same MAPI you've got the answer for in your other thread.

I would advise to debug it, I've no wm50 devices right now, so the best way is to see where it fails. I've used my own C++ wrappers under WM50 a while ago, they worked just fine, so I reckon it's just the flag somewhere, like how to get the email body: it was text at some point, then changed to be unicode text etc etc

ok, you have the source code for that mapi library, the exception is due to access violation, so it cannot release something.

the easiest is to add that project to your solution and run it debugger, MAPI is quite similar to some tables, with various properties in the 'bags', so it's quite possible that some properties are simply missing in Wm5

If it is because of access violation, then can we add access right?

no no, 'access violation' as in 'access to the memory', eg when you have NULL pointer and trying to use it, so it crashes.

I noticed now, it works fine if I am only using application. If I click any other application of system then above error raise,  like I open IE, application crash and show above error.

hmm, interesting, but can you run it under debugger and see where it crashes?

It passes debug safely without crash. I have email read at start of application. If I debug finish load event with debug then it is ok.  If I do not finish with debug, then after opening IE, it crashes.

I wait for some time with "without debug", by thinking may be system release any resource in time, but it did not work.

Please help, I am not getting it, very confused

well, this library is a wrapper for CE MAPI, ie all stuff is COM, so email store is opened, then folders (like Inbox), then messages etc etc

All this should be released at some point. I don't remember all the details re. this very library (used it a while ago), but there should be some methods to Open() something, Close() something, Dispose() and so forth.

Please check what you're doing with mapi, I have a feeling that com objects are created but never explicitly release in your code, so when GC comes to kill them something bad happens

well, we're going in circles :)

there is no other way to read emails, at least I don't know any.

you've written:

>> It passes debug safely without crash. I have email read at start of application.
>> If I debug finish load event with debug then it is ok.  
>> If I do not finish with debug, then after opening IE, it crashes.

so, for the last sentence, can you debug it or can't you? if your debugger is running, why can't you see where it fails when you start other apps?

MAPI code (not the one in the managed wrapper, but my c++ library) worked on wm5 and wm6 for years, with no problems apart from some quirks with body formats.
