Hi Remy, > > 2).-Can I intercept a "shut down" or "restart" message to process > > some code before my app is closed? > > Just use your form's OnClose or OnCloseQuery event for that. I also looking for the same command for shutdown, In my opinion just base OnClose or OnCloseQuery will be not sufficient, for example, if the application do not allow any user to close the application by press the Close button or Alt+F4, but it allow when pressing shutdown or logoff. In this case how to indentify the right command source?
