We set a form property ischanged to .t. in the interactivechange event of every control on the form. Then in the queryunload we check for lastkey() = 27 and ischanged is .t. we ask the user if they want to abort his/her changes. When we save the data the form's ischanged property is changed to .f.
We also have a global var (could be an object property instead) that is set for every user that is safety = ON or OFF. If safety is ON for the user (our var is us_safety) then the user is prompted to abort when ischanged is .t. and the user presses escape or clicks on cancel. If us_safety is OFF for that user (maintained under user settings) then there is no prompt before aborting edits for that user. It is part of the user settings when users are setup in our app. Our app requires that each user logs in.


>Hi everybody,

>In MereMortals if I press ESC the form is released. If I was typing something in the textbox, then pressed ESC - the content of what I typed is deleted and the form is released without a question. I want a question asked "Do you want to save the changes?" and if yes, what I typed should be saved...
