Neven, I had the same problem... in the end I settled for a singleton object. The form that may want to be informed registers itself (and deregisters on destroy). I keep a list of interested parties and what their interest is and then send them appropriate messages.
In this case it was a barcode despatcher.... the forms tell it if they can handle client barcode, or product barcode etc. I would have preferred an automatic method but it didnt work. :-) To: Multiple recipients of list delphi <[EMAIL PROTECTED]> Send reply to: [EMAIL PROTECTED] From: "Neven MacEwan" <[EMAIL PROTECTED]> Subject: [DUG]: PostMessage Date sent: Tue, 18 Mar 2003 22:28:28 +1200 > Hi all > > In my app I have a whole lot of forms which are embedded in a page control > of the 'Main Form' > If one one these forms wants to notify all other forms in the app of a > change, what is the best way to do it? > > Iv'e tried > > PostMessage(HWND_BROADCAST, WM_APPDATACHANGE, 0, 0); > > but none of the other forms seem to get this message, is this because I > really only have 1 form in my app? > > TIA > > > Regards Neven > N.K.
