I am faced with quite a conundrum. I have been assigned to develop a
contact database, that can be queried using many different criterion.

Now the output could be a group of 50 people that matched the
criterion, and my client wants to be able to e-mail to all of them,
preferably with a single click, just like...

send/receive a number of mail messages, reporting back to the UI thread
through the use of a Queue object. When all messages that are expected have
been received, each thread sends a final update to the UI and the method
should exit, which should terminate the...

when adding a contact in outlook in the corresponding database record.
When adding a contact to outlook, I first check if I...
