Topic: Calling Acrobat ActiveX DLL from a WebServer
Conf: (P-PDF) Developers, Msg: 118487

I created a DLL using VB.NET that calls Acrobat's set of Objects. The purpose of this is to load a PDF file with Form data and then flatten it. Here's my code:

Public Function ...
Dim AcroApp As Acrobat.CAcroApp
Dim AVDoc As Acrobat.CAcroAVDoc
Dim PDDoc As Acrobat.CAcroPDDoc
Dim myJSO As Object
AcroApp = CreateObject("AcroExch.App")
AVDoc = CreateObject("AcroExch.AVDoc")
PDDoc = CreateObject("AcroExch.PDDoc")

.... code here

End Function

This function takes in three values which it needs to locate the PDF and XFDF files.

I compiled the code to a dll file, and it works beautifully from a VB.NET Windows application.

I am now trying to call my dll from an ASP.NET aspx page. When I do so, I get the following error message:

"Cannot create ActiveX component."

It blows up at the following line within my dll:
AcroApp = CreateObject("AcroExch.App")

What's going on? Can Acrobat's objects not be called via a call from an ASP.Net webserver? r do I have to change my dll to read, "server.createobject("AcroExch.App")?

TIA! Edited to add: I changed my DLL code to read "server.createobject("AcroExch.App")", but now I get the following error: "Access is denied." It blows up at the same spot. Help!!
