How to pass data from MFC to Win 32 Console through windows messaging [modified]

[Darrel Q Pham]

Hi everyone, I have been trying to send data through windows messaging from a dialog to a windows service, both of which I have created. I can send data from the service to the dialog fine, I just let OnCopyData handle it. My windows service, with my limited knowledge, doesn't have anything like that, I think. I created a thread in my windows service to look for messages. I know I can't cast the datastructure to a LPARAM or cast back the LPARAM to my datastructure, the code below just shows as an example what I want to do. If there is a way, please let me know. I look forward to be educated by you.

void myMessageThread( VOID *)
{

MSG l\_msgMessage;	
    //Create hidden window for the dialog to capture the hwnd
hWndMain = ::CreateWindow( \_T("STATIC"), \_T("Sample"), 0, 0, 0, 0, 0, NULL, NULL, NULL, NULL);	
CString c\_CopyDataMessage;
l\_msgMessage.hwnd = hWndMain;
//Data structure I want to receive
PCOPYDATASTRUCT l\_newdata; 
    //Loop forever
while( GetMessage(&l\_msgMessage, hWndMain, 0, 0) !=100	){
	if( l\_msgMessage.message == WM\_myCopyData ){
		l\_newdata = (PCOPYDATASTRUCT)l\_msgMessage.lParam;		
	}
	TranslateMessage( &l\_msgMessage );
	DispatchMessage( &l\_msgMessage );
}

}

*bump* I know how to use shared memory and named pipes, but I want to know how to do it with Windows Messaging and for a Win 32 console app. Any help would be appreciated, even if its an answer telling me its impossible.
