Parsing A String For Special Characters In C#?

Mar 6, 2011

I am getting a string in the following format in the query string:

"Arnstung%20Chew(20)"

I want to convert it to just "Arnstung Chew". How do I do it?

Also how do I make sure that the user is not passing a script or anything harmful in the query string?

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()

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);

Chinese Characters Make The Server Think Their Special Characters And Treating Them Like Code?

May 12, 2009

I am using c# and MS SQL (express)

I have a simple web form where a user puts in their name and address and it updates straight to the SQL server. It also sends an email to let me know it's been updated, and the email contains the same information. This works very well.

The problem I have is if some one types anything in Chinese (traditional or simplified)!

The email I get is fine and displays Enligsh and Chinese, but it won't update my web form from the point of where the chinese characters were entered.

eg,

I have text boxes: First Name, Last Name, 1st Line Address and Country. If I write in English my first name but use Chinese on Last Name, and then English for Address and Country, the database will enter First Name but none of the rest. It seems it gets confused with the chinese characters and ignores everything as soon as it see's it!

I can only assume the Chinese Characters make the server think their special characters and treating them like code?

Parsing Extended Characters - Cannot Get The Location?

Oct 9, 2008

In the documents I am parsing, there are sometimes characters from the extended character set - Greek symbols and so on. I need to identify the presence of these characters. There are two characters that appear the same: "-". But one is actually from the extended character set. Character 173 to be exact. I first look for the usual "-" and if it is not found, I look for the symbol from the extended character set. I have tried the following:

[Code]....

If I try FirstSpace = Textline.IndexOf(Chr(45)), it also works. Both these characters look the same on the display and in the document, but obviously are not the same. I found the offending character using a hex editor to view the document. The values of each are 0x2d and 0xad respectively. I could simply change the document, but this requires human intervention, something I can't accept. why I cannot get the location of the extended characters?

Special Characters In SQL-Query

Jul 21, 2010

I'm fairly new to ASP.NET and have the following problem:

I add data to an Access database through a form on a aspx.-page. Now my problem is, if the user enters characters like " or & the syntax of the SQL command i send to access changes and the whole thing crashes. :-(

It should nevertheless be possible to write special characters in the Access database. How can I do that??

Seconde question:

I put a GridView under my form to display the data entries from the access database to the user. This GridView has 3 Options in every Line at the beginning (Edit, Delete and Select) by default. OK, when i klick on Delete it comes the following error message (hand-translated from german into english ;-] )

"Deleting is not suppoorted from the datasource "AccessDataSource" unless the DeleteCommand is not specified.

[NotSupportedException: Das Löschen wird von der Datenquelle "AccessDataSource2" nicht unterstützt, sofern nicht DeleteCommand angegeben wurde.]

The equvivalent error message appears when I klick on the "Edit"-Button...
How do I have to specified the Delete and EditCommand?

Gridview Not Parsing Xml Encoded Characters Correctly

Nov 5, 2010

I'm having a problem using a xml file as datasource for my gridview.

I create this xml file myself using XMLTextWriter class, the file is created parsing an existing excel file so I don't have control over the data retrieved from the excel file. Using XMLTextWriter does encode the special characters correctly, for example: <Enter> instead of <Enter>. The problem is when I try to open this created xml for editing, I use a GridView and bind all the data but special character data is not show in the row.

Excel Data: Enter E or e and press <Enter>
XML Data: Enter E or e and press <Enter>
Data in GridView: Enter E or e and press

Is there a way to force the the GridView to decode the xml attributes correctly?

.net - Put Escape Character Before Special Characters Using C#?

Aug 15, 2010

buildLetter.Append("</head>").AppendLine();
buildLetter.Append("").AppendLine();
buildLetter.Append("<style type="text/css">").AppendLine();

Assume the above contents resides in a file. I want to write a snippet that removes any line which has empty string "" and put escape character before the middle quotations. The final output would be:

buildLetter.Append("</head>").AppendLine();
buildLetter.Append("<style type="text/css">").AppendLine();

The outer " .... " is not considered special chars. The special chars may be single quotation or double quotation. I could run it via find and replace feature of Visual Studio. However, in my case i want it to be written in c# or VB.NET

Alphabetic Filtering With Special Characters

Nov 24, 2010

I have a requirment to filter out all users in the database by starting letter. so we will be having link buttons for A B C D E..... Z. If user clicks on A, all users whose name starts with A is retrieved Now the concern is, if there are users whose name starts with any special chars how they can be classified under any filters OR just copy pasting what the client asked me. In terms of filtering UTF characters, is there no way to set it up so that all 'A' (i.e. Ä, Á etc.) characters are assigned to A (i.e. some way of grouping together in an "if else" kind of rule)?

Page Validation And < (special Characters)?

Nov 19, 2008

If page validation is turned on (on by default), < and some other characters in input controls (textbox) throw a page validation exception since they are considered starting of a script or html tag.

What is the best way to deal with this situation? Should we disable page validation globally and then validate input data ourselves or is there a better way?

If page validation is disabled then are there other things we need to check for other than use parameterized data insertion in sql and Server.HtmlEncode all data before displaying back to the user?

Vb.net - CKEditor To Send Emails With [vb] - Special Characters?

Problem

Characters such as:

 -> this seems to show as a special character for blank spaces/carriage returns
’ -> this seems to show as apostrophe's

Can you reccomend some methods to cleanze my post data of these non-standard characters?

Web Forms :: DropDownList FindByText With Special Characters?

Aug 24, 2010

I have a dropdownlist which I dynamically select a list item using findbytext as long as there are no special characters. One entry in the list starts with a percent symbol which I have been unable to dyncamically select. I have confirmed that there are no spaces in the list item and have hard coded the query with the string to try to find the problem. FindByText("% Increase") I believe it has something to do with the special character but have been unable to identify a method to work around this.

VB
If
Not ddlColumns1.Items.FindByText(strDefault)
Is
Nothing
Then
ddlColumns1.Items.FindByText(strDefault).Selected = True
End If
