Sizing a rich edit control???

[xandaz]

   The thing is that ToolbarReserverdY ( i'm not sure this really matters ; there's a great chance that problem is something else ) is set upon WM_CREATE to (SM_CYÊDGE*2+ ButtonHeight)+2, and the WM_SIZE comes prior to that. The problem was that ToolbarReservedY was zeroed when WM_SIZE is processed but it's alright for WM_CREATE cause i tried to comment the WM_SIZE stuff .

i read someplace that HAL zeros unused memory pages ...

Ask him, Dave!

i read someplace that the HAL zeros unused memory pages when System Idle Process is running

The memory manager has a thread that zeroes memory, for security like steve said. Not sure if it is via hal though.

edit:I was sure I had seen it on theoldnewthing but searching msdn blogs is a fruitless exercise...

Don't give up so soon - Mark Russinovich:

The system keeps unassigned physical pages on one of several page lists in the Page Frame Number (PFN) database, each maintained as FIFO list:

    * free (available for allocation but has dirty data in it);
    * modified (previously belonging to a process but needing to be written to a backing store before it can be reused;
    * standby (still associated with a process but not included in the working set);
    * zero (zeroed out memory safe for allocation),
    * ROM (read-only memory)
    * bad (pages that failed internal consistency checks).
