WM_CONTROLHEAP
 
The WM_CONTROLHEAP message is sent to a control's owner when the control
must get a handle to a heap from which to allocate memory. (For example,
entry-field controls allocate memory to hold the text associated with the
control.)
 
Usually, an application can ignore this message, passing it on to the
default window procedure, which then returns a handle to a heap maintained
by the system for each message queue for this purpose.
 
This message does not use any parameters.
 
Return Value
 
An application should return a heap handle if it processes this message.
