I have a program with AfxBeginThread() that needs to send postmessage to the main dialog in order to change listcontrol data.
How do I achieve that, because I need to pass text I want to change and element change text to? How would I do it?
AfxBeginThread() PostMessage to change contorls

Call the API version of SendMessage (::SendMessage(hwnd, w, l) so you don't use a pointer to the dialog. The pointer to the dialog is thread-local.
The LPARAM that you pass in ::SendMessage can be a pointer to anything. If you need to pass more than one parameter then create a struct that contains all the parameters and pass a pointer to that struct. In the message handler function get the individual parameters out of the struct.
