IWMSDiagnosticEvents::get_Count
The get_Count method retrieves the number of IWMSDiagnosticEvent interfaces contained in the IWMSDiagnosticEvents collection.
Syntax
HRESULT get_Count( long* pVal );
Parameters
pVal
[out] Pointer to a long containing the number of IWMSDiagnosticEvent interfaces in the collection.
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 collection can contain a maximum of 100 IWMSDiagnosticEvent interfaces. When this limit is reached, the oldest interface in the collection is replaced by the newest. Each IWMSDiagnosticEvent interface that describes a unique server or publishing point limit is included only once in the collection, but the time and date are updated to reflect the most recent occurrence. For more information, see IWMSDiagnosticEvent::get_Time and IWMSDiagnosticEvent::get_NumberOfOccurrences.
Example Code
#include <windows.h> #include <atlbase.h> // Includes CComVariant. #include "wmsserver.h" // Declare variables and interfaces. IWMSServer *pServer; IWMSDiagnosticEvents *pDiagnosticEvents; 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; EXIT: // TODO: Release temporary COM objects and uninitialize COM.
