How to handle multiple SMS operations?
How to handle coorectly the following situation:
My app sends and receives SMS messages. When I send one and during an asynchronous call (ESmsMtmCommandScheduleCopy) I receive a message which I want to delete also asynchronously (using CMsvOperationWait), the app crashes with a E32USER-CBase:46 panic code.

I think this is because the same active object is started on two different tasks simultaneously.

The deleting can be done synchronously by calling DeleteL() on the parent entry owning the message (e.g. Inbox entry).

// parent entry id can be read from TMsvEntry
TMsvId parent = iMtm->Entry().Entry().Parent();

// switch to parent entry
iMtm->SwitchCurrentEntryL(parent);

// delete message from the parent entry
iMtm->Entry().DeleteL( msgEntryId );
