====== SAVEWARN property (Window) ======


 
==== Description ====
 
 
This property specifies whether the user should be warned that changes have been made, for example, when the user tries to close the form.
 
It is set to TRUE$ by the system when changes are made to data in data-bound controls. It is reset by the system to FALSE$ after the READ, WRITE, and CLEAR events.
 
 
 
 
==== Property Value ====
 
 
This is a Boolean property.
 
 
 
|Index Value|This should be the name of the control that triggered the SAVEWARN update.|

==== Remarks ====
 
 
For a data-bound window the system generally checks to see if it should be set at the following points:  When a control loses focus, when the current cell is changed in an edit table, and when a window is about to be closed (the control with focus is checked).
 
 
 
The system presents two ways of tracking when SAVEWARN is set by the system:
 
 
 
• By intercepting the WINDOW SYSMSG event and examining the SAVEWARNINFO message
 
• By using the SAVEWARN method in the SetDebugger stored procedure to see SAVEWARN changes in the System Monitor.
 
 
 
 
==== Example ====
 
<code>
 
//// Example - set the SAVEWARN flag and triggering control//
   
   ModifiedCtrlID = @Window : ".EDL_FORENAME"
   Call Set_Property_Only( @Window, "SAVEWARN", TRUE$, ModifiedCtrlID )
 
 
 

</code>
