DigiGuide has an internal one minute timer, when the timer fires DigiGuide checks for all shows currently being broadcast and notifies your Add-In, passing a list of DGE_PROGRAMME's and the number of programmes in the list.
Example
#include <windows.h>
#include <TCHAR.h>
#include "DGAddins.h"
extern "C" _declspec( dllexport )
void OnProgrammesOnNowA( const DGE_PROGRAMME* const arrProgramme, UINT uProgrammesCount, HWND /*hwndParent*/ )
{
OutputDebugString( _T("Addin OnProgrammeOnNow:\r\n") );
//
// NOTE: We can't use the DGE_PROGRAMME pointer (array) directly because DigiGuide
// may be sending us a different structure size than we were compiled with. If we did
// use it and then if DG adds some extra data to the structure we won't iterate to the next
// element correctly and things will go Very Bad.
LPBYTE pbyte = ( LPBYTE )arrProgramme;
//
// Iterate over all of the programmes passed in.
for( UINT u = 0; u < uProgrammesCount; u++ )
{
TCHAR szBuffer[ 2048 ];
const DGE_PROGRAMME *pProgramme = (DGE_PROGRAMME *)pbyte;
wsprintf( szBuffer, _T("\t%s %s at %d:%d\r\n")
, pProgramme->pcszChannelName
, pProgramme->pcszName
, pProgramme->stTimeStart.wHour
, pProgramme->stTimeStart.wMinute
);
pbyte += pProgramme->uStructSize;
OutputDebugString( szBuffer );
}
}
