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,
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?
Recently I started a project and added a HTML file in it. I modified the HTML file and run it in Visual Studio to see the output. When I tried to validate the HTML file, I found some strange characters got appended. This is quite annoying, although I am not able to see those unexpected characters, I wonder what is the cause of the problem. I didn't adjust anything in control panel of the IIS server, I didn't modify the Web.config file. I tried to add another HTML file and put the same content into it, the same problem occured. Could someone tell me how should I troubleshoot the problem?
I know that it is basic questions, but I am stuck here.
I have TableOne have fields: USERNAME, PID, GID, TID, SID, NEWSID. I need to write query string to check if those value is already in the table. If not, insert those value to the table.
I have a web application that users insert some comments to the database. But when they try to Write some non-Ascii character to textbox some strange characters apperars instaed of my entered characters.For example When i write ı it appears like this Ä
I uploaded my .net website precompiled under vs 2008. I do not have this issue with my site running on a webhost with .net 2.0 under sql 2005. When I login to the site, there are oriental characters:
[Code]....
Every one of the squares is an oriental character. I have tested this on two servers now. As you can see, the characters start right after the Doctype line. This is where another page is loaded on my site.
I am having a very odd issue for my website [URL]. I am seeing strange characters in the home page. visit the site [URL] to view the details The site works perfectly in local system The site is done asp 2.0 and sql server 2005. I have made the customer error mode to Off to view the issues. But the page is coming in odd characters.
I developed a website using asp.net 2.0 and sql server 2005. I m using Turkish language content as entries to database tables. But when I try to add any record from my web interface I see strange characters. for example "ş,ğ,İ," characters are viewed like Å,? characters. I set my globalization to culture turkish in web.config. So there s no problem with static data on the page and no problem with records I added earlier in my own machine. I just need to send data in a correct encoding to the database.I first thought it was about collation, but changing collation doesn t differ data sent to database, I think I need to do something from my web app, but still couldn't get any ideas.
I have strange problem with my query. I have two almost identical situations in which one query is acting as it should be while the other gives errors.
var osobaIme = (from o in db.osobas orderby o.osoba_ime select o.osoba_ime).ToList().Distinct();
I have a string with 100 characters and it is for me too long in one line. I want to make NewLine after each 25 characters. For example:
Instead: "Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua."
I'm trying to show something like "contáctenos" in uppercase, but when I use the string.toUpper() method I have the strange result "CONTáCTENOS" instead of "CONTÁCTENOS". The page "culture" is set correctly to "es-ES" and the "uiculture" too.How can I obtain the correct result if it's possible, without using regex or replace.
I want to show just a part of a string for example:
Instead: "Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua."
Just a: "Lorem ipsum dolor sit amet, consetetur sadipscing..."
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.] System.Web.UI.WebControls.SqlDataSourceView.ExecuteDelete(IDictionary keys, IDictionary oldValues) +1648440 System.Web.UI.DataSourceView.Delete(IDictionary keys, IDictionary oldValues, DataSourceViewOperationCallback callback) +89 System.Web.UI.WebControls.GridView.HandleDelete(GridViewRow row, Int32 rowIndex) +714 System.Web.UI.WebControls.GridView.HandleEvent(EventArgs e, Boolean causesValidation, String validationGroup) +869 System.Web.UI.WebControls.GridView.RaisePostBackEvent(String eventArgument) +207 System.Web.UI.WebControls.GridView.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) +10 System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +13 System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +175 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1565
The equvivalent error message appears when I klick on the "Edit"-Button... How do I have to specified the Delete and EditCommand?
I am having problems with the following update query that is part of an SQL Datasource. This query was automatically generated by VS2008 and I have formatted it so that it is easier to read.
Everything works but the [ZIP+4] field which does not update. I believe that VS2008 added the square brackets around the field name because of the plus character that it contains. If I change the ZIP+4 variable name to [ZIP+4] = @ZIP4 it still does not work. This brings up another question, I have never understood where these update queries are getting their data from.
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()
I'm currently working on this application that records a users email.
I was wondering if there was a function that would read the last 7 digits of the inputted user email and store it in a variable? Is there any way to do this?
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
[Code]....
I guess this is probably possible with a lambda expression, but I've no experience with Lambda expressions at all.
I want to display description of product in gridview, but i want to display only 15 characters on one line, I want to break it after 15 characters, I have written countchar function as follows:
public int CountChars(string value) { bool lastWasSpace = false; foreach (char c in value) { result++; lastWasSpace = false; } return result; }
I have users emails in my database and when i retrieve those usernames, i want to remove every charecter after the @ charecter in the email for example, i have myname@domain.com i want to cut that to myname.
