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 = ???
...
Next
I need to set MaxFieldLength to the number of allowable characters for the current form field being iterated over.
it's a multiline TextBox the MaxLength property does not work. At the moment I only see the option to use a CustomValidator with checking TextBox1.Text.Length on server side and perhaps in addition some Javascript client side validation.But isn't there a simpler way to do this, using the standard ASP.NET validators (RegularExpressionValidator, RangeValidator, CompareValidator, etc.)
Today my client asked to implement SMS Counter and restriction to 150 characters in SMSalert.aspx form,I have done only Validation Control. I am working with SMS for the first time.
I want to force user to type more than 6 characters in password field.we cannot usee range validator because password characters can be mix(i.e.Numeric or alphabates or special characters)
How can I set a asp.net text box to accept up to 20 characters? I was trying the range validator and I set it up to 0 min value and 20 max value. The prolem is that if I write 12933, the range validator errors appear saying "only 20 characters allowed" so I think it is adding the values.
In my text area, I should be able to enter only 72 characters per line. If I use, cols property set to 72, it is allowing more or less number of characters depending on character width.
I have a column in my repeater which allows as many as 255 characters and causes the page contents pushed away to the right if any of the record has all 255 characters in that column. How can I tell it to wrap the text after 50 characters?
I couldnt help but notice that if you have a FileUpload-control, and then try to upload a file thats bigger(in bytes) then the allowed maxiumsize, then the site crashes or some wierd "Connection problem"-page shows up, atleast for me in Firefox...
So my question is simply...is this just for me?..and if not, how do I fix this the best way?...cause the current "crash-page" aint a nice way of handeling the problem in my opinion...whould be much better to actually just show some custom-page that lets the user know that thier trying to upload a file thats way to big..
I'm developing an sms application in c#. The service that I use to send a message only allows characters form the 7 bit alphabet. I'm looking for a way to check if a message only contains characters from this alphabet.
My first idea was to split the message into a character array and then loop these characters and compare them to the alphabet. But I bet there is a much better.
I've got a sql table, that just keeps getting more and more columns added. I optimize the db as much as possible, but am curious about how many fields a table can have, and if there is a way to check if I'm getting too much data per row?
My ASP.NET MVC 2.0 web application does not maintain any session state and My production machine has n (>1) core, .NET 4.0, IIS 7.5 Integrated mode.For increased performance, I am curious if I should increase the max concurrent threads in thread pool to 12*n or should I keep the max concurrent threads as 12 but assign n worker process (w3wp.exe) to my application pool. What are the pros and cons of one over another?
I have a listview, that shows 8 rows until creating another page to navigate to to see the rest. I can't figure out where the limitation of the number of rows is coming from
I have an ambitious requirement for an asp.net 2.0 web page that contains a table (gridview), and each row in the grid contains 6 select (dropdown) controls for data entry. The number of rows that will be displayed is dependent upon the user's search parameters, which are specified in another area of the page. Unfortunately, with the default (and even basic) search parameters specified, the grid could contain several hundred rows. I've noticed that the browser, in this case IE8, starts behaving rather erratically once I reach a large number of rows -- no documented evidence for the number of rows where this begins to be a problem. For example, trying to view the source of the page results in a message from IE stating that there was a problem with the page that forced the browser to reload it, and I never get the source. Obviously the page loads and renders rather slowly also.
I know that my solution is probably going to involve paging the gridview such that it only displays 20 or so rows per page, and I'll have to write code to handle the saving of changes in the dropdown values when the user changes pages. I can probably turn off viewstate on the gridview also. However, the question I really want to pose is this -- has anyone seen a documented rule indicating the maximum number of input controls that an HTML browser form is supposed to be able to contain? I could not find anything on the Internet after doing a search, and I suspect the answer may be whatever the browser can handle based on the machine configuration it is running on. Any rules of thumb you use?
one of our programmers is having an issue with a asp.net app. i had him rebuild and recompile the app to the network share on the staging server and received the same error. i even deleted the files in this folder
(C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files). to make sure that the server was not the issue i installed it on another server and received the same error. i found a article on msdn that states that its a source code issue. Compiler Error Message: BC30041: Maximum number of errors has been exceeded. Source Error:

I have an HTML markup which has HTML Table and Images in it. I am using iTextSharp API to convert the HTML markup to PDF. But, unfortunately the iTextSharp fails to export the HTML markup containing the Images & Table to PDF.
Error: The network path was not found.
using iTextSharp.text; using iTextSharp.text.pdf; using iTextSharp.text.html; using System.Data.SqlClient; using System.Text; using iTextSharp.text.html.simpleparser;
[Code] ....
I know this error is due the Image Path. But, not able to resolve.
I want to create PDF in a folder and not be able to downloadable to user.
