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.
