I am using the following code to decode base 64 and quoted printable encoded messages. It works well for all the charset's except for quoted printable chinese (Charsets: GB18030, GB2312). When I tried to decode, I am getting '?' as output. provide on this code or any other code that decodes all types of encoded string?

MY page will be reciving a post method . There i need to decode a hexa value to string that is present in the url .
The url format is as follows
POST /yourserver/yourhandler?Hex-Message=54657374.
I know that I could use HttpServerUtility.UrlTokenDecode Method to do the job. But the problem is that I am using .NET 1.1 and this method is only supported in .NET 2.0+. Also I found that Convert.ToBase64String method is not an option because of the differences addressed here. So what other options do I have? Do I have to write my own converting method?
View 1 RepliesI 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);
I am creating a web site in .Net 3.5 , I am converting the string into Base64String to send it through querystring.The Response.Redirect works fine for smaller string. But if the original string size is 1670,the response.redirect results in error "Page can not be found".item is the string in below code snippet.
byte[] data = Encoding.Default.GetBytes(item);
return Convert.ToBase64String(data)
I encrypt and decrypt a string with a private key and following functions. so I encrypt a string with Encrypt function and decrypt the encrypted string with decrypt function. If someone can change the encrypted string and then it decrypts with decrypt function, the decrypted string isn't equal to plain text before encrypting. I want to know how can I check is decrypted string equals to plain text before encrypting?

i am failing to get the Base64 string and show it as an image in the output pdf file.
I have a signautre canvas that saves the output directly into the sql database.
I'm running into following error: "The viewstate is invalid for this page and might be corrupted." "Invalid character in base64 string." Only with IE 8.0. Firefox works fine. The persisted view state is

i.e. two identical parts separated by a comma. I'm using a form with both jQuery and UpdatePanel. I've inspected the __VIEWSTATE hidden field before the post __doPostBack and $I.System.InvokePageMethod. In both cases the viewstate does NOT contain the comma. where the field gets doubled up with the comma inserted? Or how to fix.
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.
I have been presented with numerous word and excel docs. The goal is to put them online and bind to a database for the fields and also to store data for easy searching and reporting.
Has anyone done anything like this before?
I know the easy solution would be to create a database table for each particula form and also an ASP.net page for each form.
But then there are problems like printing and correct formating so it fits on the page, spaning multiple pages and so on.
And also is there any advice on how to write to PDF straight from the page?
i'm using a little javascript in my website for my navigation bar, which is made up of a few ImageButton controls. in the code behind i have this:
Dim homeImage As String = GetLocalResourceObject("HomeImage")
imgBtnHome.Attributes.Add("OnMouseOver", HomeImage)
and in the resx file, i've tried these, but they don't work: (note the single and double quotes)
key: HomeImage value: "this.src='images/HomeImage.gif'"
key: HomeImage value: "this.src='images/HomeImage.gif'"
is it even possible to read "quoted" text from a local resource file?
I have been trying to do this for some time with no luck...
The user registers an item into our database and is then presented with the just inserted details. This item requires a couple of labels, a CD Face label, a CD Inlay label and a barcode label for the packaging. Previously this was done by word templates which had a form on opening to gather the info. Each item then (in theory) requires the user to put in some basic facts 4 times if you include the original registration.
The issue I have is with internet explorer I guess, or the presentation of the data... For instance our barcode printer uses labels which are 5cm x 7cm. Anything remotely larger will not print correctly. So I make a formview with everything set out as 4cm x 6cm and set the page setup to 4.5 x 6.5. it then printed across 4 labels. This is quite frustrating as the print has to be consistent and is reliant upon the user setting quite a few items before trying to print!
So my next excursion was with Word. Create an Interop.Office based way of filling fields in on a template that I knew printed everytime bang on. After the faf of CSID issues and permissions to launch applications, I found that it would work if I was running it using the ASP.net test environment, but on the server it just spawned winword.exe over and over !!!!!!!
The ideal way for me would be that a formview is printable, the ideal way for the user is using word but automate the items being filled in, however I can't seem to get either to work correctly!
I want to make a grid that the users will print and that will display it's rows in different colors on the printable versionI'm using ASPXIt seems that even you make the colors right, when you print it , the colors are disapearing

View 3 RepliesWhat 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:

I want to make a data url from an existing file on the system.
@Convert.ToBase64String() wil do the trick but how do i convert a 'webimage' to a byte array?
Or is there a project to convert 'anything' to a data uri?
I have to send a file to my webservice, but the webservice assumes the file (byte Array) as a base64Binary.
Before the encoding, the byteArrayFile is saved on disk as a regular File. (I'm doing it just for testing)
So, in my Java client for webservice, I'm sending the information this way:
String file = new sun.misc.BASE64Encoder().encode(byteArrayFile);
port.sendFileToWebService(file);
The webservice have to decode the information and save the received file on disk.
