The following C# code example invokes a process named MyApplication/EncryptDocument from
a Microsoft .NET project using data over HTTP. (See Invoking LiveCycle using BLOB data over HTTP.)
An unsecured PDF document based on a PDF file named Loan.pdf is
passed to the LiveCycle process using BLOB over HTTP. The process
returns a password-encrypted PDF document that is saved as a PDF
file named EncryptedPDF.pdf.
/*
* Ensure that you create a .NET client assembly that uses
* SOAP over HTTP. This is required to populate a BLOB
* object's remote URL data memeber.
*
* For information, see "Invoking LiveCycle using BLOB data over HTTP" in
* Programming with LiveCycle
