Initialize RTC

  • Article

The following code example demonstrates the creation and initialization of the RTC object.

Note  This example does not contain error checking or releases appropriate for real code.

C++ Code Example

HRESULT hr = S_OK;

// RTC Initialization 
// Note: Use the apartment threaded model because
// RTC applications are not thread safe.
::CoInitializeEx(NULL,COINIT_APARTMENTTHREADED);

// Create the RTC Client COM object. 
IRTCClient      *pIRTCClient;

hr = CoCreateInstance( CLSID_RTCClient,
                       NULL,
                       CLSCTX_INPROC_SERVER,
                       IID_IRTCClient,
                       reinterpret_cast<void **> (&pIRTCClient) );

// If (hr != S_OK), process the error here. 

// Initialize the RTCClient interface. 
hr = pIRTCClient->Initialize();

// If (hr != S_OK), process the error here.

Visual Basic Code Example

' Set the error handling routine here. 
' On Error GoTo MyErrorRoutine 

'Declare the global RTC Client object.
Private g_objRTCClient As RTCClient

'Create the RTC Client object, usually performed during form load.
Set g_objRTCClient = New RTCClient

'RTCClient needs to be initialized before any other method can be 
called on it.
Call g_objRTCClient.Initialize
