IWMSDiagnosticEvent::get_NumberOfOccurrences
The get_NumberOfOccurrences method retrieves the number of times the event notice has occurred.
Syntax
HRESULT get_NumberOfOccurrences( long* pVal );
Parameters
pVal
[out] Pointer to a long containing the number of event occurrences.
Return Values
If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.
Return code | Number | Description |
E_POINTER | 0x80004003 | pVal is a NULL pointer argument. |
Remarks
The get_NumberOfOccurrences method is relevant only for limit events. When a limit event occurs, the value is incremented and the IWMSDiagnosticEvent::get_Time value is updated.
Example Code
#include <windows.h> #include <atlbase.h> // Includes CComVariant. #include "wmsserver.h" // Declare variables and interfaces. IWMSServer *pServer; IWMSDiagnosticEvents *pDiagnosticEvents; IWMSDiagnosticEvent *pDiagnosticEvent; HRESULT hr; CComVariant varIndex; long lCount; // Initialize the COM library and retrieve a pointer // to an IWMSServer interface. hr = CoInitialize(NULL); hr = CoCreateInstance(CLSID_WMSServer, NULL, CLSCTX_ALL, IID_IWMSServer, (void **)&pServer); if (FAILED(hr)) goto EXIT; // Retrieve a pointer to the IWMSDiagnosticEvents // interface and retrieve the total count of events. hr = pServer->get_DiagnosticEvents(&pDiagnosticEvents); if (FAILED(hr)) goto EXIT; hr = pDiagnosticEvents->get_Count(&lCount); if (FAILED(hr)) goto EXIT; // Retrieve information about each diagnostic event. for (long x = 0; x < lCount; x++) { varIndex = x; hr = pDiagnosticEvents->get_Item(varIndex, &pDiagnosticEvent); if (FAILED(hr)) goto EXIT; // Retrieve the number of times this event occurred. hr = pDiagnosticEvent->get_NumberOfOccurrences(&lCount); if (FAILED(hr)) goto EXIT; // Release temporary COM objects. pDiagnosticEvent->Release(); } EXIT: // TODO: Release temporary COM objects and uninitialize COM.
