Important: In order to create a digital signature, you must first have a valid PKCS#12 certificate (*.pfx) file.

To use the code below, change the path and file name to point to your PFX, and change "password" to the password for your PFX file. You can use a third-party digital ID, or create a self-signed certificate.

For information on creating a self-signed certificate, see the Adobe Acrobat Help topic "Create a self-signed digital ID."

You can also create a PFX file from the Visual Studio command line. For more information and links to SDK downloads, see http://www.source-code.biz/snippets/vbasic/3.htm.

The following code samples assume that you have a report variable rpt, and that you have dragged the PDFExport object onto your form.
