I send a message to a already running application from one that has just 
been started.  This works just fine AFAIK except when I try to get to 
the LParam.  Eventually I expect to retrieve a char string. I get this 
error:

[C++ Error] Main.cpp(171): E2316 'WParam' is not a member of 'tagMSG'

I'm perplexed since I got this line from another post by a TeamB member.

Nate

void __fastcall TFormMain::AppMessage(MSG &Msg, bool &Handled)
{
   if( (Msg.message == WM_MYMSG) && (WM_MYMSG != 0) )
     {
     COPYDATASTRUCT* cds = reinterpret_cast 
<COPYDATASTRUCT*>(Msg.LParam);  // compile error
     FileList->Clear();      // TStringList *
     Application->Restore();
     Show();
     Handled = true;
     }
   else
     Handled = false;
}
