Use ITextSharp To Determine Text Field's Maximum Number Of Characters Allowed?

Oct 6, 2010

I have a PDF document with a number of text fields, several of which have a maximum length - namely, a maximum number of allowable characters. Is there a way using iTextSharp to determine this setting? Here's the code I have so far:

Dim reader As New iTextSharp.text.pdf.PdfReader("Foobar.pdf")
Dim inputFields As IDictionary(Of String, iTextSharp.text.pdf.AcroFields.Item) = reader.AcroFields.Fields
For Each key As String In inputFields.Keys
Dim PDFFieldName As String = key
Dim MaxFieldLength As Integer = ???

I need to set MaxFieldLength to the number of allowable characters for the current form field being iterated over.

I'm using user membership and roles. Below is my web.config for subfolder restriction.


The way I have above, no one can access this folder, mySub, except Administrators, Editors, and Members. However, here's what I want. I want to allow all and any user to the default.aspx page of this mySub folder and denied any other pages if they're not Administrators, Editors, and Members. One last thing, also denied access to addWord.aspx if they're not Administrators and Editors. I know I can list all the pages and give them various permission but I do not want to list all the pages. What's the best and easist way to accomplish this?

As you can see I have tried to restict it also through the web.config file but neither approach has worked.

Security :: Restricting Access To One Page Not The Whole Website?

Jan 29, 2011

I'm trying to restrict access to one page on my website. However, the code I'm using doesn't seem to work for this purpose. I can get the code to work by removing the following out of the web.config.

<deny users="?" />

This works fine by preventing access to the page unless a password is entered. However, I've realised that if I type the page name into the browser this will by-pass the login page and allow access to the page I want to lock down.
