Hi priya,

You cannot insert ActiveX control as you mentioned.
To insert a control into your project using VC++
you need to do the following.

VC++-->Project-->Add to project--> Components and controls.

that will popup a dialogbox,
select Registered ActiveX controls, then pdf.
When you do this, it will insert a class which is derived from CWnd.
So you may need to first instantiate an object of this class,
before using any of its methods.

Are you using Acrobat full version or Acrobat reader.
ActiveX control will work with both Full version and reader.

But if you are using full version of acrobat,
then you can use IAC,
for which you have to add new class from type library as you said,
from Acrobat.tlb file.

Look under Acrobat folder of your installation for Acrobat.tlb file.
When you add class from acrobat.tlb,
this will add a set of classes into your project.
First you need to call
CreateDispatch("AcroExch.App");
for instantiating/loading the acrobat.
then u can use any object from the class list.

Hope this helps,
Jabir.

Subject: Printing a PDF file from C++




Hello,

I would greatly appreciate suggestions from C++/
ActiveX folks for the following:

I would like to "silently" print PDF files from a
C++ dll. What are the possibilities ?

I have the Acrobat ActiveX control (pdf.ocx) on
my machine. I am able to use this control from
VB to (effortlessly) print a PDF file.
Pdf1.LoadFile ("c:\\acrguide.pdf")
Pdf1.printAll() -- that's all !

However, I can't do the same from my C++ program.

I used MS Visual C++-->View->ClassWizard->Add Class From a Type Library to
add the pdf.ocx into my existing
C++ project. This generates Pdf.h and Pdf.cpp files.
(where class _DPdf : public COleDispatchDriver).

The code is:
HRESULT hr = CoInitialize(NULL);
CLSID refID;
hr = CLSIDFromString(L"{CA8A9780-280D-11CF-A24D-444553540000}", &refID);

_DPdf *pdf = new _DPdf();
pdf->CreateDispatch(refID, NULL);
pdf->LoadFile("c:\\acrguide.pdf");
pdf->Print();
delete pdf;

CoUninitialize();

The code craps out when pdf->LoadFile is invoked.
CreateDispatch returns OK.
(LoadFile and printAll are in the pdf.ocx).

Any suggestions ? Am I missing anything ?

Thanks & Regards
Priya
