Example Code
#include <windows.h> #include <atlbase.h> // Includes CComBSTR and CComVariant. #include "wmsserver.h" // Declare variables and interfaces. IWMSServer *pServer; IWMSNamedValues *pNamedValues; IWMSNamedValue *pNamedValue; HRESULT hr; CComVariant varIndex; CComVariant varValue; CComBSTR bstrName; 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 an IWMSNamedValues interface // containing descriptive information about the server. hr = pServer->get_Properties(&pNamedValues); if (FAILED(hr)) goto EXIT; // Retrieve the total count of name-value pairs. hr = pNamedValues->get_Count(&lCount); if (FAILED(hr)) goto EXIT; // Retrieve information about each name-value pair. for (long x = 0; x < lCount; x++) { varIndex = x; hr = pNamedValues->get_Item(varIndex, &pNamedValue); if (FAILED(hr)) goto EXIT; // Retrieve the value associated with this pair. hr = pNamedValue->get_Value(&varValue); if (FAILED(hr)) goto EXIT; // Release temporary COM objects. pNamedValue->Release(); } EXIT: // TODO: Release temporary COM objects and uninitialize COM.
