NULL Reference Exception when creating IacDocument

[EmbTrak]

I need to open a PDF document and paint it to my own Graphics object.

The first step in that appears to be creating a IacDocument.


IacDocument * aiDoc;

aiDoc = new IacDocument(NULL);

That 2nd line yields a Null Reference Exception. What's going on that I can't even get to square one?

Thanks.

I'm back to PDFCreator after experimenting elsewhere ... trying again.

According to the VS Object Browser, a new IacDocument wants a System.Windows.Forms.ScrollableControl as an argument to the constructor. So I have put a Panel named panel1 on my form. System.Windows.Forms.Panel inherits from System.Windows.Forms.ScrollableControl, so this should be good:


IacDocument * aiDoc;
aiDoc = new IacDocument(panel1);

I still get the NULL Reference Exception.

What am I doing wrong?

thanks.

The declaration of the the document object is as follows:

IacDocument document = new IacDocument( null )

However you need to initialize the library and activate it first by calling:

// initialize the library and set our license key
acPDFCreatorLib.Initialize();
acPDFCreatorLib.SetLicenseKey(licensee, activationCode);

Hope this helps.
