In .net streams are by default encoded in utf-8. so what i want to do is to simply read the text in a textbox in which i paste the russian characters and then convert them to ascii. but when i debug the code then in my resulting string ? appears. how i can convert the string into its ascii equivalent. my code is given below
string inputString = txtName.Text;
ASCIIEncoding ascii = new ASCIIEncoding();
Encoding encoder = ASCIIEncoding.GetEncoding("us-ascii", new EncoderReplacementFallback(string.Empty), new DecoderExceptionFallback());
byte[] bAsciiString = encoder.GetBytes(inputString);
string cleanString = ascii.GetString(bAsciiString);
I am outputing a text file of 1s and 0s. I want to shrink the file so I'm going to convert it to ascii. Its going to be used on a clientside web application so I can convert it back to binary with some scripting later on.
So, I want to convert the string of binary to a string of ascii serverside in vb.net. I have spent much time searching the web for a vb.net solution, and, what a mess!! everyone thinks they know how to do it, but none of the solutions have worked so far!!

I am trying to prevent users from submitting ascii codes in a textbox using a RegularExpressionValidator.
This works fine and I am able to display an error.
However when the user clicks on another button on the page I get the "A potentially dangerous Request.Form value was detected from the client" error. Is there a way to prevent this?
I have an ASP.NET TextBox with TextMode = TextBoxMode.MultiLine that is used within an AJAX Update Panel. The .Text value has been pre-set to a value that has multiple lines.
When using Chrome(7.0.517.41) or Firefox(3.6.11) working with the controls posted back value on the server the carriage return is lost if the user hasn't edited the pre-set value.
In my project I am displaying word file in textbox. While users reading their data in textbox(uploaded as word)some unformatted fonts that is table in word coming like some type of fonts how to overcome this.
I am working on writing some code to scrub user input to my ASP.NET site. I need to scrub input to remove all references to ASCII characters 145, 146, 147, 148 which are occasionally getting input from my mac users who are copying and pasting content they write in a word processor on their macs.
My issue is the following three strings I am led to believe should output the same text.
I get a blank value for test1, test2 works correctly, and test3 outputs as a '?'.
Can someone explain what is happening differently. I am hoping this will help me understand how .NET is using ASCII values for characters over 128 so that I can write a good scrubbing script.
EDIT The values I mentioned (145 - 148) are curly quotes. So single left, single right, double left, double right.
By "works correctly" I mean it outputs a curly quote to my browser.
SECOND EDIT The following code (mentioned in an answer) outputs the curly quotes as well. So maybe the problem was using ASCII in test 3.
THIRD EDIT I found a mac that I could borrow and was able to duplicate the problem. When I copy and paste text that has quote symbols in them from Word into my web app on the mac it pastes curly quotes (147 and 148). When I hit save curly quotes are saved to the database, so I will use the code you all helped me with to scrub that content.
FOUTH EDIT Spent some time writing more sample code based on the responses here and noticed it has something to do with MultiLine TextBoxes in ASP.NET. There was good info here, so I decided to just start a new question: http://stackoverflow.com/questions/2215547/asp-net-multiline-textbox-allowing-input-above-utf-8
,What does the [0] in this code stand for ?I know the line gets the number of bytes in the ASCII characters, if its less than 91 and greater than 64.But why the [0] string str = strs[i]; if (Encoding.ASCII.GetBytes(str)[0] <= 64 || Encoding.ASCII.GetBytes(str)[0] >= 91) { Console.WriteLine(Encoding.ASCII.GetBytes(str)[0].ToString()); } else if (Encoding.ASCII.GetBytes(str)[0] != 88) { Console.WriteLine(str); }
I have what I think is a weird issue. I send text from one page to another via Session Variable. When page 2 loads, the text box has the session text set, but if the user changes the text and clicks the button, the SQL database is update with the original session text. If I remove the redirect from the page 2 button_Click method, then, the page refreshes with the textbox reverting to the session text and thr SQLDataSource has the session text added to it.
I have a page with a text box, a button and a GridView. Enter an account number in the text box, press the check button and the result will show in the GridView.
Now user wants that if the text box is clear, the GridView disappear.
I can only find TextBox1_OnTextChanged. But I want to have that while the user is clearing the text, if the length of text becomes zero, the GridView is clear out. So I am looking for OnTextChanging(). Well of course this function does not exist. How to achieve the same purpose?
I have an asp page with a textboxes, labels and other controls. I cannot get the .text to change in any of these controls. I click on button which I execute code that I expect to update the text but it doesn't work. Something like Textbox1.text = "Hello" Are there page level properties/settings I should look at? I am perplexed an looking for a place to start. I will provide more information as needed. I just don't know where to start.

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.
