Thanks for the information and direction. I got it working now.
My application was a MFC C++ Dialog based program using VS2008.

The most difficult part was getting the first parameter in the PostMessage() call.
This was the HWND hWnd of the main window. I used a global variable g_hMainHWND so that it was available in both the interrupt and main program.

Code as follows:-
C++
//In the header file
#define	Digital_Event		1
// Message for 1553 interrupts
	afx_msg LRESULT OnDigitalInterrupt(UINT wParam, LONG lParam);

// In the Main MFC file of the application
const UINT WM_INTERRUPT_DIGITAL = WM_APP + 1;
HWND	g_hMainHWND;

BEGIN_MESSAGE_MAP(CDigitalPnPDlg, CDialog)
	ON_WM_SYSCOMMAND()
	ON_WM_PAINT()
	ON_WM_QUERYDRAGICON()
	// Interrupt for Digital
	ON_MESSAGE(WM_INTERRUPT_DIGITAL, OnDigitalInterrupt)

// In the Dialog Init routine
	g_hMainHWND = this->GetSafeHwnd();

LRESULT CDigitalPnPDlg::OnDigitalInterrupt(UINT wParam, LONG lParam)
{
	/* This routine is called every 20 msec by the interrupt from the
		board. 	*/
	if(wParam == Digital_Event)
		manage_timers();
	return 0;
}


// In the interrupt routin
	/* Arrange for the processing of the 20 msec interrupt in the main application	*/
	PostMessage(g_hMainHWND, WM_INTERRUPT_DIGITAL, Digital_Event, NULL);


Note I was using the interrupt to provide a timer facility as the card was providing this every 20 msec.

Andy
