Acrobat DLL Exception (Transforming pdf to tif)

M

Mauro

I'm trying to use the following VB function to transform a pdf
document to a tiff one:
http://forums.microsoft.com/msdn/sh...27&siteid=1&sb=0&d=1&at=7&ft=11&tf=0&pageid=1

Private Sub savePDFtoTIF(ByVal fullPathPDF As String, ByVal
fullPathTIF As String)
Dim PDFApp As Acrobat.AcroApp
Dim PDDoc As Acrobat.CAcroPDDoc
Dim AVDoc As Acrobat.CAcroAVDoc
Dim JSObj As Object

' Create Acrobat Application object
PDFApp = CreateObject("AcroExch.App")

' Create Acrobat Document object
PDDoc = CreateObject("AcroExch.PDDoc")

' Open PDF file
PDDoc.Open(fullPathPDF)

' Create AV doc from PDDoc object
AVDoc = PDDoc.OpenAVDoc("TempPDF")

' Hide Acrobat application so everything is done in silent
mode
PDFApp.Hide()

' Create Javascript bridge object
JSObj = PDDoc.GetJSObject()

' Attempt to save PDF to TIF image file.
' SaveAs method syntax .SaveAs( strFilePath, cConvID )
' For TIFF output the correct cConvid is
"com.adobe.acrobat.tiff"
' cCovid MUST BE ALL LOWERCASE.
JSObj.SaveAs(fullPathTIF, "com.adobe.acrobat.tiff")

PDDoc.Close()
PDFApp.CloseAllDocs()

' Clean up
System.Runtime.InteropServices.Marshal.ReleaseComObject(JSObj)
JSObj = Nothing


System.Runtime.InteropServices.Marshal.ReleaseComObject(PDFApp)
PDFApp = Nothing

System.Runtime.InteropServices.Marshal.ReleaseComObject(PDDoc)
PDDoc = Nothing

System.Runtime.InteropServices.Marshal.ReleaseComObject(AVDoc)
AVDoc = Nothing

End Sub

It gives an exception at line PDFApp = CreateObject("AcroExch.App")
=> Cannot create ActiveX component

I have acrobat 8. Do I need to install SDK or some other component?

Hi,
You need to register the ActiveX component using the regsvr32.exe utility

How can I find the path of the file to register?
I have Adobe Reader 8.1.2 without SDK now.

Thank you.

Mauro

Could you be more specific?
I can't understand what do I have to search and how can I locate the
file. It's in the Acrobat program directory?

Thank you.

Hi,
Please install the PDF SDK and normally during the installation process
itself it will register the dll.

Once the installation is complete check for the following entries in registry:

HKEY_CLASSES_ROOT\AcroExch.App
HKEY_CLASSES_ROOT\AcroExch.App.1
HKEY_CLASSES_ROOT\AcroExch.AVDoc
HKEY_CLASSES_ROOT\AcroExch.Document

regards,
Joy

I have the Adobe Reader 8.1.2 and I've installed the SDK 7.0.5 since
I've not found the SDK for my version.
In the registry I've founded only the key:
HKEY_CLASSES_ROOT\AcroExch.Document
the other keys are missing.

I have the key:
AcroExch.Document
AcroExch.Document.7
AcroExch.FDFDoc
AcroExch.Plugin
AcroExch.RMFFile
AcroExch.SecStore
AcroExch.Sequence
AcroExch.XDPDoc
AcroExch.XFDFDoc

Any Idea?

Thank you.

I have Adobe Reader Standard 8.1.2: I read in the forums I could use
standard version.

Now I've done the job in a different way, because I was in an hurry
(not using Adobe API),

I think I'll investigate this problem in my spare time (not much in
the last years :( )

Hi Mauro,
Nice to know that you have been able to accomplish the task in some
different way, but do share with us that you have done.

I've launched a Ghostscript process that converts PDF into TIFF. Dirty
but simple and functional
