IXMLDOMDocument::get_implementation
The get_implementation method retrieves a pointer to an IXMLDOMImplementation interface for the document.
Syntax
HRESULT get_implementation( IXMLDOMImplementation** ppImpl );
Parameters
ppImpl
[out] Pointer to a pointer to an IXMLDOMImplementation interface for this document. This method calls AddRef internally. To avoid memory leaks, you must call Release when you are finished using the interface.
Return Values
If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.
Remarks
An XML DOM application can use objects from multiple implementations. This method provides access to a pointer to an IXMLDOMImplementation interface that handles this document.
Example Code
The following example retrieves a pointer to an IXMLDOMImplementation interface.
#include "wmsserver.h" #include <atlbase.h> // Includes CComVariant and CComBSTR. // Declare variables. IWMSServer* pServer; IXMLDOMDocument* pPlaylist; IXMLDOMImplementation* pXMLImp; HRESULT hr; CComBSTR bstrFeature; CComBSTR bstrVersion; CComVariant varFile; VARIANT_BOOL bIsSuccessful; VARIANT_BOOL bHasFeature; // 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; // Create the playlist object. hr = pServer->CreatePlaylist(&pPlaylist); // Load a sample playlist file. varFile = "c:\\wmpub\\wmroot\\simple.wsx"; hr = pPlaylist->load(varFile, &bIsSuccessful); if (FAILED(hr)) goto EXIT; if (bIsSuccessful) { //Retrieve a pointer to an IXMLImplementation interface. hr = pPlaylist->get_implementation(&pXMLImp); if (FAILED(hr)) goto EXIT; } EXIT: // TODO: Release temporary COM objects and uninitialize COM.
