Cannot create a PKCS1 object in VB6 (using COM) to sign a PDF document which has a SignatureField

Good morning,

I am wring a program with VBA/VB6. I have created a typelibrary and registered the aspose.pdf component with regasm, and referenced the tlb in my project (I cannot see the methods and properties of the classes from the object browser).

I have created a SignatureField in a PDF document with ASPose.Pdf and this works fine.

I try now to Sign the PDF document using the mehod Aspose.Pdf.Facades.PdfFileSignature.Sign(SignatureField, Reason, Contact, Location, Signature)

I created an object PKCS1Signature = CreateObject("Aspose.Pdf.InteractiveFeatures.Forms.PKCS1")

But since this Class does not expose the pfx and password methods, I do not know how to set those parameters.

I tried also to use the SetCertificate method, but I always get the same 430 error stating that the Class does not manage Automation.

How can I perform the signature of my document?

Thanks for your help.

Best regards,

Jorge
