WMRMProtect.Header

The Header property specifies and retrieves the content header.

Syntax

  WMRMProtect
  .Header = String
String = WMRMProtect.Header

Parameters

This property takes no parameters.

Return Values

If the property succeeds, it returns a String containing the header. If it fails, it returns a number in the error object.

Return code Description
0xC004290C The header cannot be larger than 8 kilobytes.
0x80004005 An unspecified error occurred.
0x80070057 The specified parameter is not valid.

Remarks

The header can be no larger than 8 kilobytes. You can use the WMRMHeader object to manipulate the header. You must call the Header property before calling either the WMRMProtect.ProtectFile or WMRMProtect.WriteFile methods.

Example Code

      Dim sKID, sCID, sSeed, sKey, sHeader
    Dim sPrivKey, sPubKey
    Dim HeaderObj
    Dim KeysObj
    Dim ProtectObj

' Create objects.

    Set HeaderObj = Server.CreateObject("Wmrmobjs.WMRMHeader")
    Set KeysObj = Server.CreateObject("Wmrmobjs.WMRMKeys")
    Set ProtectObj = Server.CreateObject("Wmrmobjs.WMRMProtect")




















' Require individualization version 2.2.
' Version numbers change. Verify that this number is up to date.

.IndividualizedVersion="2.2"
















HeaderObj.SetCheckSum(sKey)

' Replace XXX with the packaging server's private key. 

    = "XXX"

' Sign the header.



' Retrieve the string containing the header.

    sHeader = HeaderObj.Header

' Set the header string into the WMRMProtect object.

    ProtectObj.Header = sHeader

' Set the key into the WMRMProtect object.

    ProtectObj.Key = sKey

' Specify the name of the file to be protected.

    ProtectObj.InputFile = "c:\input_file.wmv"

' Generate a protected file.

    ProtectObj.ProtectFile("c:\output_file_1.wmv")
