Parameters
- wParam
-
Not used; must be zero.
- lParam
-
Not used; must be zero.
Return value
The return value is zero. This message cannot fail.
Remarks
A rich edit control groups consecutive typing actions, including characters deleted by using the BackSpace key, into a single undo action until one of the following events occurs:
- The control receives an EM_STOPGROUPTYPING message.
- The control loses focus.
- The user moves the current selection, either by using the arrow keys or by clicking the mouse.
- The user presses the Delete key.
- The user performs any other action, such as a paste operation that does not involve typing.
You can send the EM_STOPGROUPTYPING message to break consecutive typing actions into smaller undo groups. For example, you could send EM_STOPGROUPTYPING after each character or at each word break.
