Retrieves the state of an edit control's modification flag
#include <GuiEdit.au3>
_GUICtrlEdit_GetModify ( $hWnd )
| $hWnd | Control ID/Handle to the control |
| True: | Edit control contents have been modified. |
| False: | Edit control contents have not been modified. |
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 True.
You can call _GUICtrlEdit_SetModify() to set or clear the flag.
