Determine If A String Only Contains Characters From The Seven Bit Alphabet(c#)

Mar 16, 2011

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.

7 big alphabet:

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.

How To Fix Special Characters In String

Aug 3, 2010

I've got a program that in a nutshell reads values from a SQL database and writes them to a tab-delimited text file.

The issue is that some of the values in the database have special characters (TM, dash, ellipsis, etc.) When written to the text file, the formatting is lost and they come across as junk "â„ or â€" etc"

When the value is viewed in the immediate window, before it is written to the txt file, everything looks fine. My guess is that this is an issue of encoding. But, I'm not real sure how to proceed, where to look, or what to look for.

Is this ASCII or UTF-8? If it's one of those how do I correct it before it's written to the text file.

Here's how I build the text file (where feedStr is a StringBuilder)

objReader = New StreamWriter(filePath)
objReader.Write(feedStr)
objReader.Close()

Feb 9, 2011

I need to be able to sort by a product title and then by a products price, which is simple but I only want the title sorted on the first 3 or 4 characters. My client wants to add the brand name to the beginning of the product title and have them automatically sorted. I can a new field in the database called brand and sort by that, but wanted to know if this is possible. I've posted what I though might work but it doesn't

I guess this is probably possible with a lambda expression, but I've no experience with Lambda expressions at all.

Strange Characters While Trimming String

Feb 21, 2011

using vb.net/asp.net 2005 and sql server 2005. I'm querying the database and returning text which I am then adding to a string. I'm creating a crystal report with the text however this is not a crystal report question, its about the string data. what I"m noticing is that when I show the string on the pdf that there are some strange characters at the end of the string. I am both trimming the string and taking out null characters however the strange text shows up like this:

strangeText>
SÙÇ
TÙçy|Ü
DÙÇ
$ÛÇ
</strangeText>

does anyone know what these characters are and how to get rid of them?

How To Insert String With Special Characters Into RTF

Jan 20, 2010

How to programatically insert string with special characters into RTF? I have rtf template I load to string and then replace all $MY_VARIABLE$ with data. Data contains special chars like 'ąęść' and the problem is that in result file these characters are replaced with '?'. It's something wrong with encoding but what?

My code looks like:

StreamReader reader = new StreamReader("template.rtf");
StringBuilder form = new StringBuilder(reader.ReadToEnd());
// here I replace variables in rtf with data
Encoding srcEncoding = new UTF8Encoding();
Encoding dstEncoding = new ASCIIEncoding();
byte[] utf = srcEncoding.GetBytes(form.ToString());
byte[] asci = Encoding.Convert(Encoding.UTF8, Encoding.ASCII, utf);
return dstEncoding.GetString(asci);

C# - How To Use Strange Characters In A Query String

Apr 14, 2010

I am using silverlight / ASP .NET and C#. What if I want to do this from silverlight for instance,

// I have left out the quotes to show you literally what the characters
// are that I want to use
string password = vtakyoj#"5
string encodedPassword = HttpUtility.UrlEncode(encryptedPassword, Encoding.UTF8);
// encoded password now = vtakyoj%23%225

URI uri = new URI("http://www.url.com/page.aspx@password=vtakyoj%23%225");

HttpPage.Window.Navigate(uri);

If I debug and look at the value of uri it shows up as this (we are still inside the silverlight app),

[URL]

So the %22 has become a quote for some reason.

If I then debug inside the page.aspx code (which of course is ASP .NET) the value of Request["password"] is actually this,

vtakyoj#"5

Which is the original value. How does that work? I would have thought that I would have to go,

HttpUtility.UrlDecode(Request["password"], Encoding.UTF8)

To get the original value.
