Edit I'd misunderstood what was happening here.. there is a POST send, then receive back a result, then the URL string which I'm seeing here is part of the the query string... so I can't decode what this really is, as it is encoded by the payment gateway people and not me.
I'd like to decode a URL string
Here is the code:
[Code]....
While adding the parameters to get/post request they need to be encoded in application/x-www-form-urlencoded form. So do we need to encode values each time ? Does JavaScript have any method for that ? What are the possible caches ?On server side when we read the values we do not decode them we directly say Request.Params["key"] and that returns value. Does that mean that they are automatically taken care when we read the values?

I'm storing some html-encoded data in a sql server database and I've written a script to output the data in a csv format minus the html tags and I'm getting a weird issue when html-decoding the remaining data. For example the data contains a quote character (which is html-encoded as ’), but when I try to html-decode it the data comes out as a series of weird characters (’). Does anyone know how to solve this issue? The output encoding of the page is UTF-8 if that helps.
View 2 RepliesI'm trying to send a string of XML as part of the query string. Normally I'd POST this XML but I'm sending it to a 3rd party system that I can't POST stuff to. So, as it goes, I need the 3rd party system to request the services of one of the pages in my system. (explanation: the 3rd party system produces PDFs of my web pages. I give it a URL to my page, and it PDF's that page. So, the XML file contains data that I need to generate the page) Anyway, I'm getting my query string as follows:
string data = Server.UrlEncode(xmlSnippet.ToString());
string sFullUrl = urlString + "?data=" + data;
I give the 3rd pary system this URL, and it calls my page.. except the request doesn't reach the page. It's failing into the Application_Error handler with this message:
"A potentially dangerous Request.QueryString value was detected from the client (data=[my XML data])" As I know the data I'm sending is safe, is there any way I can make this work?
It seems the following markup is rendered differently in Firefox and Chrome, and I'm not sure how to prevent it:
<%= HttpUtility.UrlEncode("+") %>
<%= "<a href='#' name='" + HttpUtility.UrlEncode("+") + "'>stuff</a>"%>
In Firefox it looks like:
%2b<a name="+" href="#">stuff</a>
In Chrome it looks like:
%2b<a name="%2b" href="#">stuff</a>
Is there a way around it?
I'm having problems with a bit of code, where i'm trying and failing to read the EXIF data from jpg files. I cannot figure the error, although everything I've been able to find online points toward the same thing: my code is correct. The code is as follows.
[Code]....
The only error i get is a javascript error in IE8, stating Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed.". I have absolutely no idea what it's doing, why it's going wrong or how it's failing.
I have a Response filter setup to transform the html before spitting back out to the browser [URL]. This works fine on everyones machine but mine. Actually it was working on my machine until I had to do a hard reset because it locked up.
public override void Write(byte[] buffer, int offset, int count)
{
string strBuffer = System.Text.UTF8Encoding.UTF8.GetString(buffer, offset, count);
For everyone else (and mine previosly) strBuffer contains HTML. Now for whatever reason it's returning junk characters for me.
Update
Turns out that "Enable dynamic content compression" is causing the issue. For some reason it's getting gzipped before being passed into the filter.
Solution
Setting the "dynamicCompressionBeforeCache" to false in the web.config fixed the issue.
<urlCompression doStaticCompression="true" doDynamicCompression="true" dynamicCompressionBeforeCache="false" />
I am working on a Japanese File and I have no knowledge of the language. The file is encoded in S-JIS. Now, I am supposed to convert the contents into UTF-8 so that the content looks like Japanese. And here I am completely blank. I tried the following code that I found somewhere on Internet but no luck:
byte[] arrByte = Encoding.UTF8.GetBytes(arrActualData[x]);
string str = ASCIIEncoding.ASCII.GetString(arrByte);

What is the best way to encode the url in Hyperlink without writing code behind. I have many uses and I would like to do it in the Hyperlink statemeent if possible. Some thing such as the following would be great:
(This does not work)

ID="HyperLink1"
NavigateUrl=
"<%=UrlEncode(~/All_Videos.aspx?tag=full length movie&title=The Movie)%>"runat="server">Movies</asp:HyperLink>
I have a list of character that display fine in WebBrowser in the form of encoded characters such as € � ... But when posting these characters onto server to I realized that HttpUtility.HtmlDecode cannot convert them to characters as browser did, they all become space.
text = System.Web.HttpUtility.HtmlDecode("€");
I expect it to return € but it return space instead. The same thing happen for some other characters as well.
I am trying to render html encoded string that is stored in SQL Server into human readable form. The HttpUtility.Decode does not decode the text that is rendered in between the open tag and closing tag of any input tag (ie. TextBox or TextArea or Select) in my ASPX page. However, HttpUtility.Decode works fine if the text is not in an input tag. The following is my test code. For example, the value of AdmitDX field in database is "Someone's comment" which is "Someone's comment" when decoded. The first two code nuggets <%%> will show as "Someone's comment" and the thrid code nugget will show "Someone's comment".
<!-- the following two lines have html encoded text, instead of html decoded text -->
<%= Html.TextArea("AdmitDX", HttpUtility.HtmlDecode(thisTransfer.AdmitDX))%>
<%= Html.TextBox("AdmitDX", HttpUtility.HtmlDecode(thisTransfer.AdmitDX)) %>
<!-- the next line works fine -->
Test = <%= HttpUtility.HtmlDecode(thisTransfer.AdmitDX) %>

My problem is with .Net Http/Uri libraries not being able to decode or unescape this character sequence: "Hi%E1". Neither Uri.UnescapeDataString nor HttpUtility.UrlDecode can do it.
Although I have a solution to get around this problem ( http://stackoverflow.com/questions/1221849/url-decoding-confusion ) I would like to understand why it is failing.
The 1st test here throws an exception! The second just fails.
Assert.That(Uri.UnescapeDataString("Hi%E1"), Is.EqualTo("Hiá"));
HttpUtility.UrlDecode("Hi%E1").ShouldBe("Hiá");
There is nothing in the docs to indicate that UnescapeDataString or UrlDecode are restricted to character sets or any reason why these tests would fail. However, from testing, it would appear that HttpUtility assumes UTF-8 (or some other) encoding.
The Java equivalent works! Probably because it allows an encoding to be set.
URLDecoder.decode("Hi%E1","windows-1252"); // this works btw, ie passes tests
Which looks like a very sensible move considering the .Net work-around (see URL above)
Are the .Net implementations of these methods just crap and .Net devs just have to write their own - or am I missing something?
BTW Everything I know of in IIS set to UTF-8, and Chinese/Japanese characters show fine, so I don't yet know how it could it be that this URI consists of windows-1252 encoded characters. If I could fix the URI to contain UTF-8 encoding, that would be a better way of fixing this.
