i am developing a web site in which i need keyboard handling. My code for keyboard handling is working properly, but the problem is this, it produce same ASCII code for small and capital alphabets. For example when I execute my web site and press "A" without Caps-Lock it produce 65 ASCII code which is actually code of capital "A", But logically it has to produce "97" code of small "a"..

View 2 RepliesI am creating my application in asp.net 3.5. I have to make my Data Access layer, in which I am doing the traditional method of fetching/updating the data. Which is SqlConnection than SQLCommand, than SQLadapter. Will there be any other way I can create my DAL layer easily.
Specification.
My website is small. Approx 7-10 pages. Database has around 80 tables.
What I know:
Linq to SQL - I don't want to use it because I am not fully aware about the LINQ statement and I need to develop the application really fast. [3 days :-( ]. Also, there are 100% chances that the table structure will be altered in future. Enterprise Library: It will take too much time for me to integrate to my application.
I'm trying to build a small website that is required register and login
I want to use Linq to SQL to do that.
So, have an ASP 3.5 site built using ELMAH.
It runs fine under IIS 5.1, I can see all the error pages, etc.
Set up the site on another machine running IIS 7.5.
Now when I go to my /admin/elmah.axd page, i see a 404 error from IIS 7.5.
CI have been producing a registration form using html and asp. I have managed to get it to send an email having copied script from a previous website which someone developed for me. I now get the response going to the old address and with then old text. How can I change it all to the new site?
View 4 RepliesI created one page in that i placed a gridview, in that I view only 10 rows using paging concepts. In that i know to set numeric. that is, at botton of the page the next page will be as 2,3,4,5,6,.....100.
Instead of this numeric i want to place a alphabets, that is a,b,c,d,...
I have a datatable which has been dynamically generated from FoxPro tables using a UNION Select statement. e.g.
SELECT * FROM x UNION SELECT * FROM y UNION SELECT * FROM Z ORDER By v_alue1
This produces a datatable with about 100 rows, each containing many fields, one of which is c_olor. From this datatable, I would like to select the distinct colors and then output in a dropdown.
I have a public class Color which just has one property which I can then use as the DataTextField and DataValueField for the dropdownlist
[code]...
However this never results in the distinct colors.
I have searched and searched for what I am looking for, and this seems to be one of the methods to produce a distinct set of results, but this and the others do not work.
My reasoning behind getting the colors this way, is that I need to get various other distinct values from the same UNION SELECT datasource, so would just do one DB call, cache the results, and then just used this cached datasource to retrieve all my distinct values.
So here's the deal. I'm creating a spider bot for a website that scans all the product pages and records the product data. I'm using C# and the WebClient library to download the HTML string. The site I'm crawling must be specially made because the HTML that is received from WebClient.DownloadString() is different than the HTML that I get when I view the source of the HTML when visiting it on a browser. This seems intentional because the only info I can't get is the price.

View 3 RepliesI have a requirement to display alphabets above each datagrid column names (like shown in excel). The datagrid columns (and header text) are dynamically created at run time and the alphabets on top could grow like excel A, B, C,....Z, AA, AB, AC,.....AZ etc. Any suggestions on how to get the alphabets showing for each columns?
View 1 RepliesI am not sure what you call it in other technologies, on the IBM i (or iSeries) we call it overlays. The overlay is an image of a form that is stored on the server then a program generates the form with fields from the database so you can eliminate preprinted forms.
I had a problem last year with the method I was trying at the time. It was a rush job at the time to be revisited at a later point. The work-around at the time was to export to PDF. So now it is "later" and once again is a rush (imagine that). This is all done through a web-based interface.
So how do you generate forms from something that was once a preprinted form? What method do you recommend? This is a legal form and must be filled out a certain way and can have many in a batch (up to 50 or so). I would prefer to not have them print one page at a time.

I saw this code it is good but,I have to insert letters inside the markers?
If the marker is yellow color we have to insert 'y' inside that yellow color markers,if it is blue 'b' have to insert.
How would I?
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.
string test1 = Convert.ToChar(147).ToString();
string test2 = String.Format("'{0}'", Convert.ToChar(147));
char[] characters = System.Text.Encoding.ASCII.GetChars(new byte[] { 147 });
string test3 = new string(characters);
Yet when I set an ASP TextBox to equal the following
txtShowValues.Text = test1 + "*" + test2 + "*" + test3;
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.
char[] characters2 = System.Text.Encoding.Default.GetChars(new byte[] { 147 });
string test4 = new string(characters2);
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
I will have my string as follows
String S="AB-1233-444";
From this i would like to separate AB and would like to find out the ASCII for that 2 alphabets.
,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);
}
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 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.
My computername is in non-ascii character like ÄÖßÜÄÖßÜ. I am opening the web application using the url http://localhost/test/login.aspx. It opens with that url. But when i try to open with the url like http://ÄÖßÜÄÖßÜ/processmanager/login.aspx, it is not opening the page.

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?
