Important Note:

No method should ever dispatch a DDE message or allow a DDE message to

be dispatched.
|

Therefore, no method should ever enter a message dispatch loop.
|
|
Also, a method should not show a dialog or message box, because the

processing of the dialog box messages will allow DDE messages to be

dispatched.
