ActiveX component cant create object AcroExch.App

Report · Oct 15, 2007

I have read an article about accessing PDF's using Acrobat SDK and downloaded Acrobat 7.0.5 SDK version and installed it.

Later I have uninstalled the 7.0.5 SDK version, downloaded SDK8_v2_Full_win.zip and extracted it to C:\Program Files\Adobe folder. I have acrobat reader 8.1.0 installed in my machine.

Now when I run the following code from an automation tool (QTP),Iam getting an error : ActiveX component cant create object AcroExch.App .

Option Explicit
Dim gApp, gPDDoc, jso
Set gApp = CreateObject( "AcroExch.App" )
Set gPDDoc = CreateObject( "AcroExch.PDDoc" )
If gPDDoc.Open( "c:\MyPdfFile.pdf" ) Then
Set jso = gPDDoc.GetJSObject()
jso.console.Show
jso.console.Clear
jso.console.println ( "Hello, Acrobat for QuickTest!" )
gApp.Show
End If
Set jso = Nothing : Set gPDDoc = Nothing : Set gApp = Nothing

Article author told me to check the following keys in registry: -
HKEY_CLASSES_ROOT\AcroExch.App
HKEY_CLASSES_ROOT\AcroExch.App.1
HKEY_CLASSES_ROOT\AcroExch.AVDoc
HKEY_CLASSES_ROOT\AcroExch.Document

I was able to find only 'AcroExch.Document' key in registry my machine.

"AcroExch.App" is not registered, that's why I got the eroor and installation of the SDK did not work in my system.

Please let me know how to get acrobat SDK successfully installed?

I need only to open or print a PDF, that's all I want

I need Acrobat to create PDF using his virtual printer but I can't deny a user to install a newest reader for his needs.

With a Acrobat Reader installed is possible to open a PDF using Acrobat instead of the Reader ?

If I can manage this problem by code I can later use the CreateObject to print a different document, now to open a PDF I'am using in VB6:

ShellExecute(0, vbNullString, sFile, 0&, 0&, 1)

but this open the PDF using the Reader

The AcroExch methods are not in Reader. But according to the
documentation, FilePrintSilent is supported in Reader. What happens
when you try to use it?

You should tell the user that Adobe don't support it. Of course, Adobe
would prefer an Acrobat upgrade any way.

If you start Acrobat first BEFORE trying to open the file, Acrobat
should do all the processing.

AcroExch.App doesn't exist if Reader is the only viewer on the machine. AcroExch.App only works with a full version of Acrobat.

> I need Acrobat to create PDF using his virtual printer but I can't deny a user to install a newest reader for his needs

I can certainly understand that in a large deployment, but that doesn't change the fact that Adobe considers it unreliable to have multiple versions installed, and it may well cause unexpected behaviour.

Yes, but since this is unsupported by Adobe. You'll have to manually edit the registry to move the file associations and browser integration back to Acrobat. Adobe provides no documentation for this since, in their opinion, you shouldn't have 2 versions installed on the same machine.

Basically, you can think of it this way: Whichever product was installed most recently will be the "active" viewer (i.e. the one that holds the associations and browser integration).

I know but I have also an Acrobat 5.0 FULL installed, if the Reader is not open the CreateObject works fine.

I can understand if I have 2 full version installed, but have an old FULL version and a newest Reader version I don't think is strange.

With Reader 8.0 the code raise the error "Foreign application won't perform DDE method or operation", the code is:

Dim lngTID As Long

'// Open Acrobat Reader
lngTID = Shell(GVAcrobatPath, vbHide)

'// Print in silent mode my pdf file
tb.LinkMode = vbLinkNone
tb.LinkTopic = "acroview|control"
tb.LinkMode = vbLinkManual
tb.LinkTimeout = 32767
tb.LinkExecute "[FilePrintSilent(""" & sFile & """)]"

Does that DDE code work with older versions of Reader/Acrobat?

Yes, I've been tested the code with a Reader 7.0.

A couple of responses...

First, FilePrintSilent was turned off in Reader 8 due to security concerns. You can, however, print with a UI.

Second, let me clarify the multi-version policy and rationale.

* Adobe does not support multiple versions of Adobe Acrobat installed on the same computer.

* Adobe does not support multiple versions of Adobe Reader installed on the same computer.

* Adobe DOES support one copy of Reader and one copy of Acrobat PROVIDED THAT both are of version 7.0 or later.

Now, the reasoning is simple. Acrobat and Reader each want to install certain system-level components (eg. printer drivers and browser plugins) that DO NOT play well with older versions!

However, with Acrobat & Reader 7, we recognized the common situation where a user would update their Reader before their Acrobat - and so we have designed the products to live together IN THAT ONE CASE.

Hope that helps.

Ok

What you mean with "print with a UI"? Use the Reader user interface?

I don't understand why only the automation does not work with a new versione of Reader when automation should concern only a full Acrobat.

So Acrobat 7 FULL with Reader 7 o 8 should work?

Thx, bye
