EM_SETMODIFY
An
application sends an EM_SETMODIFY message to set or clear the modification flag
for an edit control. The modification flag indicates whether the text within
the edit control has been modified. It is automatically set whenever the user
changes the text. An EM_GETMODIFY message can be sent to retrieve the value of
the modification flag.
EM_SETMODIFY
wParam = (WPARAM) (UINT) fModified; // modification flag
lParam = 0; // not used; must
be zero
Parameters
fModified
Value of wParam.
Specifies the new value for the modification flag. A value of TRUE indicates
the text has been modified, and a value of FALSE indicates it has not been
modified.
Return Values
This message
does not return a value.
Remarks
In a rich
edit control, objects created without the REO_DYNAMICSIZE flag will lock in
their extents when the modify flag is set to FALSE.
