IWMSOutgoingDistributionConnection::get_RequestedURL

The get_RequestedURL method retrieves the URL that the client used to request a distribution connection.

Syntax

  HRESULT get_RequestedURL(
  BSTR*  pVal
);

Parameters

pVal

[out] Pointer to the BSTR containing the URL.

Return Values

If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.

Return code Number Description
DISP_E_BADINDEX 0x8002000B The value does not exist.
E_POINTER 0x80004003 pVal is a NULL pointer argument.

Remarks

The URL that is returned by the get_RequestedURL method can be different than that requested by the client. For example, if the client requests mms://servername/movie.wmv, the get_RequestedURL method can return either mmsu://servername/movie.wmv or mmst://servername/movie.wmv, depending on the type of connection that is used by the session.

Example Code

#include <windows.h>
#include <atlbase.h>    // Includes CComBSTR and CComVariant.
#include "wmsserver.h"

// Declare variables and interfaces.
IWMSServer                          *pServer;
IWMSOutgoingDistributionConnections *pConnections;
IWMSOutgoingDistributionConnection  *pConnection;

HRESULT         hr;
CComVariant     varIndex;
CComBSTR        bstrURL;
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 a collection of distribution
// connections and retrieve the total count of connections.
hr = pServer->get_OutgoingDistributionConnections(&pConnections);
if (FAILED(hr)) goto EXIT;
hr = pConnections->get_Count(&lCount);
if (FAILED(hr)) goto EXIT;

// Retrieve information about each distribution connection.
for (long x = 0; x < lCount; x++)
{
    varIndex = x;
    hr = pConnections->get_Item(varIndex, &pConnection);
    if (FAILED(hr)) goto EXIT;

    // Retrieve the requested URL of the client.
    hr = pConnection->get_RequestedURL(&bstrURL);
    if (FAILED(hr)) goto EXIT;

    // Release temporary COM objects.
    pConnection->Release();
}

EXIT:
    // TODO: Release temporary COM objects and uninitialize COM.
