Item open events and double click events in exchange client extension.

[Fanxa]

I'm using VC++8.0 to developer an Exchange Client Extention for outlook2003.
In IExchExtCommands:oCommand(LPEXCHEXTCALLBACK lpeecb, UINT cmdid) method
I can catch the Item open action like this:
if( 0x003c == cmdid){ // Menu item "Open" command
// do something...
hr = S_FALSE; // Must return S_FALSE
}
If I click the menu item 'Open',it works fine.But,when I open the mail item
by double-click the item,I can't get it work.I don't want to use OOM and
fire the ItemEvents which hold a method called 'Open',so how can i solve it?
