EM_GETMODIFY message

Gets the state of an edit control's modification flag. The flag indicates whether the contents of the edit control have been modified. You can send this message to either an edit control or a rich edit control.

Parameters

wParam

Not used; must be zero.

lParam

Not used; must be zero.

Return value

If the contents of edit control have been modified, the return value is nonzero; otherwise, it is zero.

Remarks

The system automatically clears the modification flag to zero when the control is created. If the user changes the control's text, the system sets the flag to nonzero. You can send the EM_SETMODIFY message to the edit control to set or clear the flag.

Rich Edit: Supported in Microsoft Rich Edit 1.0 and later. For information about the compatibility of rich edit versions with the various system versions, see About Rich Edit Controls.
