startHeader, endHeader, startHeaderElement, and endHeaderElement Methods (Windows Embedded CE 6.0)

  • Статья

1/6/2010

These methods create a <Header> element for a SOAP message.

These four methods work together in the following way:

  • The startHeader method indicates the beginning of a <Header> element.
  • The startHeaderElement method indicates the beginning of a child element of the <Header> element.
  • The endHeaderElement method indicates the end of a child element of the <Header> element.
  • The endHeader method indicates the end of the <Header> element.

This <Header> element is optional. Therefore, if you do not call these methods when building a SOAP message, the SOAP message does not have a header.

Syntax

HRESULT startHeader( 
  BSTR enc_style_uri 
);
HRESULT startHeaderElement( 
  BSTR name,
  BSTR ns_uri,
  int mustUnderstand,
  BSTR actor_uri,
  BSTR enc_style_uri,
  BSTR prefix
);
HRESULT endHeaderElement(void);
HRESULT endHeader (void);

Parameters

  • enc_style_uri
    [in] Optional. Value of the Universal Resource Identifier (URI) for the encodingStyle attribute of the <Header> element. The following values have special meaning when assigned to this parameter.

    Value Description

    NONE

    Default. Use this value if you do not want encodingStyle attribute generated in <Header> element.

    STANDARD

    Use this value if you want to generate encodingStyle attribute with the default encoding style in the <Header> element.
  • name
    [in] Name of the <Header> element.
  • ns_uri
    [in] Optional. Universal Resource Identifier (URI) for the namespace of the <Header> element. The default is "". If this parameter is missing or is an empty string, the element is in the default namespace.
  • mustUnderstand
    [in] Optional. An integer that indicates whether the SOAP server must understand and be capable of processing a <Header> element. The default is 0. If set to 1, then the SOAP server must be able to process a <Header> element. If the server does not understand the header, it must return a <Fault> element in the SOAP message to the client. If this parameter is missing or is 0, the <Header> element does not include the mustUnderstand attribute.
  • actor_uri
    [in] Optional. Value of the actor attribute of the <Header> element. The default value is "". If this parameter is missing or is an empty string, the <Header> element does not include an actor attribute.
  • prefix
    [in] Optional. Namespace prefix used for the element. The default is "". If this parameter is missing or is an empty string, the application generates a namespace prefix as needed.
