How can I use ABCpdf to retrieve custom document properties?

This page gives a helpful example of how to set custom document properties for a pdf.

So I've done this (and I've verified that the custom property is set in the file):

Doc theDoc = new Doc();
int theID = theDoc.AddObject("<< >>");
theDoc.SetInfo(-1, "/Info:Ref", theID.ToString());
theDoc.SetInfo(theID, "/Company:Text", "ACME");
theDoc.Save(FileName);

I'm trying to retrieve the property at a later time. I've tried:

Doc theDoc = new Doc();
theDoc.Read(FileName);
int theID = theDoc.AddObject("<< >>");
theDoc.SetInfo(-1, "/Info:Ref", theID.ToString());
return theDoc.GetInfo(theID, "/Company:Text"); //returns empty string

and

//...read theDoc
int theID = theDoc.GetInfoInt(-1, "/Info");
return theDoc.GetInfo(theID, "/Company:Text"); //returns empty string

Anybody have a clue as to how I can retrieve that property?

Solution

  • I found another way to set these values:

    if (theDoc.GetInfo(-1, "/Info") == "")
    theDoc.SetInfo(-1, "/Info:Ref", theDoc.AddObject("<< >>").ToString());
theDoc.SetInfo(-1, "/Info*/Company:Text", "ACME");

    After setting the values in this way, I'm able to retrieve them like so:

    if (theDoc.GetInfo(-1, "/Info") == "")
    theDoc.SetInfo(-1, "/Info:Ref", theDoc.AddObject("<< >>").ToString());
string companyName = theDoc.GetInfo(-1, "/Info*/Company:Text");
