(SQL Server) Signed SOAP for www.sist.puglia.it/Schemas/PDD_SIST/SCATEL/ using BinarySecurityToken

Creates a signed SOAP request for www.sist.puglia.it/Schemas/PDD_SIST/SCATEL/ using a BinarySecurityToken.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows

// Important: See this note about string length limitations for strings returned by sp_OAMethod calls.

CREATE PROCEDURE ChilkatSample

BEGIN
    DECLARE @hr int
    DECLARE @sTmp0 nvarchar(4000)
    -- This example requires the Chilkat API to have been previously unlocked.
    -- See Global Unlock Sample for sample code.

    -- Create the following pre-signed SOAP XML:
    -- Note: We'll be constructing a placeholder for the wseBinarySecurityToken in the soapenv:Header.
    -- Chilkat will automatically replace the "BinarySecurityToken_Base64Binary_Content" with actual data when signing the XML.

    -- However: Your application should insert the actual desired timestamp values for wsu:Created and wsuExpires
    -- Typically this is the current system date/time and a few minutes from the current system date/time.
    -- The example below shows a 5 minute window.  We'll write code below to insert the current date/time and the current date/time + 5 minutes..
