IWMSAdminNetworkDataSourcePlugin::SetProxyCredentials

The SetProxyCredentials method specifies the user name and password that can be used to connect to a proxy.

Syntax

  HRESULT SetProxyCredentials(
  BSTR  bstrProtocol,
  wchar_t*  bstrName,
  wchar_t*  bstrPassword,
  VARIANT_BOOL  fPersist
);

Parameters

bstrProtocol

[in] BSTR containing the protocol. This must be either HTTP or RTSP.

bstrName

[in] Pointer to a wchar_t containing the name.

bstrPassword

[in] Pointer to a wchar_t containing the password.

fPersist

[in] Flag indicating persistent credentials.

Return Values

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

Return code Number Description
NS_E_INVALID_REQUEST 0xC00D002B The bstrProtocol parameter must be HTTP or RTSP.

Remarks

Before returning, this method zeros out the memory used internally for the user name and password so that unencrypted local copies cannot be found on the computer on which Windows Media Services is running.
