[2.0] I need help on PDF Files ... tnx

1. How would i know if the type of file is a PDF file?
2. To determine the number of pages of a PDF File.

* please use c#

Thanks in advance ...

Welcome to the forum.

Can't we use FileStream method for that. I said that based on Java, not at best in C#. Hope it will work.

There is a PDFParser class as well. May be it will help you. I found it on MSDN.

Thanks

The first four charaters of a valid pdf file will should be:

Code:

---

%PDF-

---

Code:

---

using Acrobat;
using AFORMAUTLib;
private void DisplayPDFPageNumber(string FilePath)
        {
            AcroPDDocClass objPages = new AcroPDDocClass();
            objPages.Open(FilePath);
            long TotalPDFPages = objPages.GetNumPages();
            objPages.Close();
            AcroAVDocClass avDoc = new AcroAVDocClass();
            avDoc.Open(FilePath, "Title");
            IAFormApp formApp = new AFormAppClass();
            IFields myFields = (IFields)formApp.Fields;
            firstPageNumber = myFields.ExecuteThisJavascript("event.value=this.getPageLabel(0);");
            long lst = TotalPDFPages - 1;
            lastPageNumber = myFields.ExecuteThisJavascript("event.value=this.getPageLabel('" + lst + "');");
            avDoc.Close(0);           
        }

This code is used to get the pdf page number.
You can get the first page number and the last page number.
