Outlook 2007 crash

Z

Zuber

Hello,

I am working on an issue related with add-in for Outlook 2007. I need some
help fixing it.

The issue is,

I have written some code to handle the OnSelectionChange() event. I am
calling a function from OnSelectionChange() which in turn invokes
GetSelectionItem() and works on that item.

The OnSelectionChange() event is fired twice or thrice when the selection
changes. It works fine if I move between messages in the same folder, but
when I select a different folder Outlook 2K7 crashes. The reason being; when
folder selection changes the first event to get fired is for the selected
message from the previous selected folder rather than for the new selected
folder. The second event is for the folder.

The code expects the newly selected item to be a folder rather than a
message item, the code crashes due to this.

FYI, the same code works on Outlook 2003. I am not sure if anything changed
for Outlook 2007, or something more is required from my end.

Thanks in advance for any solution.

Thanks and Regards,

Zuber

I don't think I have ever seen this. What is your code? How do you declare
the variable assigned to the items in the SElection collection?

Hello Dmitry,

On further investigation I found that with Outlook 2003, the events are
fired the same way as for Outlook 2007. For OL2003, the events that are fired
on folder change are:

1. OnSelectionChange() for mail from previous folder
2. OnSelectionChange() for new folder
3. OnSelectionChange() form mail in new folder

On OL2007, only the first event is fired.

Here is a skeleton of the code:

OnSelectionChange( LPEXCHEXTCALLBACK lpeecb )
{
CComQIPtr<IUnknown, &IID_IUnknown> spUnk = lpeecb;
UpdateSelection(spUnk);
}

UpdateSelection(LPEXCHEXTCALLBACK lpeecb)
{
CComPtr<IExchExtCallback> m_spExchCallback;
m_spExchCallback = lpeecb;
m_spExchCallback->GetSelectionItem ( i ,&cbEID, &pEID, &ulType, szMsgClass,
SOTC_MSGCLASS_SIZE,
&dwMsgFlags, 0) );
if ( MAPI_MESSAGE == ulType )
{
AddItem(pNewSelection);
}
}

If I comment out, GetSelectionItem() it works properly otherwise OL crashes.

The "LPEXCHEXTCALLBACK" comes from the Exchange55 SDK. Is the Exchange55 SDK
compatible with OL 2007 ?

Thanks and Regards,

Zuber

Hmmm.. I stopped using ECE in Outlook 2007 (I still use them in the previous
versions of Outlook), so I can't really verify what is going on.
Does this happen for any folder or just the Calendar folders?
I remember a similar issue in Outlook 97 where GetSelectionItem() will choke
if called from OnSelectionChange.
I worked around that by posting 0xF449 command using

PostMessage(hwndExchange, WM_COMMAND, 0xF449, 0);

where hwndExchange comes from IEXCHEXTCALLBACK::GetWindow() and doing the
processing in DoCommand().

This happens if you switch between any folders.

Hi Dimitry,

Your workaround solution of PostMessage() just seem to have worked for me too.

Looks like GetSelectionItem() does not work if used from OnSelectionChange()
for Outlook 2007.

I am doing some tests to check if it has really fixed the issue.

Thanks for all your help.

Hi Dmitry,

The workaround solution of using PostMessage() worked for me, but its
causing other problems. I have a customized context menu for messages which
was working before this change but it has now stopped working. Outlook fails
to bring up the customized context menu and instead shows the default Outlook
context menu. Investigating further shows that the Message Handler for
WM_SHOWPOPUP never gets invoked.

Any thing in addition to PostMessage() needs to be done ? Any help for this
is appreciated.

Thanks in advance.

Zuber

I can only suggest that you rewrite your ECE as a COM add-in - installation
will be a lot easier, and I suspect that ECE saupport will be at least
limited in the next version of Outlook.
