In adition to what Dennis wrote.
You can find the definations of the VCL messages in Messages.hpp, 
using the right message structure usually gives nicer code when 
using the message. 
  
e.g.
void __fastcall TMyPanel::WMMouseMove(Messages::TWMMouse &Msg)
{
   TPanel::Dispatch((void*)&Msg);
   //do things with Msg.XPos or Msg.YPos
}

Dispatch is used to make sure that the message is passed on to 
the ancestor. I most cases You must use Dispatch otherwise things
don't work correctly.       



P.s. Please manually breake Your text lines, due to code lines
most of us have turned of auto linebreak, which makes it hard
to read when people don't break lines.

Kind regards
Asger
