IWMSAdminNetworkDataSourcePlugin::get_TCPEnabled
The get_TCPEnabled method retrieves a Boolean value indicating whether the data source plug-in can use TCP when selecting a streaming protocol.
Syntax
HRESULT get_TCPEnabled( VARIANT_BOOL* pVal );
Parameters
pVal
[out] Pointer to a VARIANT_BOOL indicating whether TCP can be used.
Return Values
If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.
Example Code
#include <windows.h> #include <atlbase.h> // Includes CComVariant. // To access system plug-in interfaces, the // entire type library must be imported as shown. #import "WMSServerTypeLib.dll" no_namespace named_guids \ raw_interfaces_only // Declare variables and interfaces. IWMSServer *pServer; IWMSPlugins *pPlugins; IWMSPlugin *pPlugin; IDispatch *pDispatch; IWMSAdminNetworkDataSourcePlugin *pAdminNetDataSrc; HRESULT hr; VARIANT_BOOL bEnabled; CComVariant varIndex; // 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 IWMSPlugins interface // containing data source plug-ins. hr = pServer->get_DataSources(&pPlugins); if (FAILED(hr)) goto EXIT; // Retrieve a pointer to the IWMSPlugin interface // of the plug-in to be configured. varIndex = "WMS Network Data Source"; hr = pPlugins->get_Item(varIndex, &pPlugin); if (FAILED(hr)) goto EXIT; // Retrieve a pointer to the custom interface // of the plug-in. hr = pPlugin->get_CustomInterface(&pDispatch); if (FAILED(hr)) goto EXIT; // Query the specific administration interface // for the plug-in. hr = pDispatch->QueryInterface(IID_IWMSAdminNetworkDataSourcePlugin, (void **)&pAdminNetDataSrc); if (FAILED(hr)) goto EXIT; // Retrieve a Boolean value indicating whether TCP // can be used as a streaming protocol. hr = pAdminNetDataSrc->get_TCPEnabled(&bEnabled); if (FAILED(hr)) goto EXIT; EXIT: // TODO: Release temporary COM objects and uninitialize COM.
