to set restrictions on the pdf document you can do this either using the PDF Converter or the PDF Creator but you need to have the Professional version of these products.

If you are using the PDF Converter to generate the pdf document, you can then open the generated PDF and encrypte it.

Example DLL interface:

Code: Select all

SetLicenseKeyA LicenseTo, ActivationCode
EncryptPDFDocument "c:\Temp\Test.pdf", "Owner", "User", -64
EncryptPDFDocument128 "c:\Temp\Test.pdf", "Owner", "User", -64
Example ActiveX interface:

Code: Select all

 Dim doc as new CDintfEx.Document
doc.Open "C:\Temp\Test.pdf"
doc.SetLicenseKey LicenseTo, ActivationCode
doc.Encrypt "owner", "user", -64     '40 bits encryption
doc.Encrypt128 "owner", "user", -64    '128 bits encryption
doc.Save "C:\Temp\Encrypted.pdf"
The permission values are:

Code: Select all

-64+4     EnablePrinting
-64+8     Enable document modification
-64+16   Enable copying text and graphics
-64+32   Enable adding and changing notes
To combine multiple options you can use -64 plus the values 4, 8, 16, 32. eg to enable both printing and adding notes you can use -64+4+32 = 28. To disable all 4 options you need to use -64.

Hope this helps.
