How do I send/post messages?

Hello,
I have a main form with 3 panels. I would like one panel to send a new WM message to the other panels.
I found some help about adding event handlers but I don't know how to actually send the message (after filling the lParam and wParam parametrs).
An example would be very helpful.

Thanks,
Tommy

Hi tommyq,

you can use PostMessage or SendMessage.

SendMessage waits until message is processed, postmessage puts the message in the qeue and returns.

With Objects you can also use Perform. (like sendmessage, it waits until message is processed) :

RetVal := ObjectName.Perform(MessageID, wParam, lParam);

or

 SendMessage(hWnd, MessageID, wParam, lParam);

 PostMessage(hWnd, MessageID, wParam, lParam);

Regards, Zif.
