Encoded String Length Greater Than Max Specified For User?
Apr 4, 2011
I'm using ASP.NET with sql-server. I have an area where the user can enter text of a maximum amount. I encode this text as a good measure but the encoded length can be greater than this maximum amount when I try to insert it into the database.
Special characters are encoded on 3 characters. I can't show the user that he has exceeded the max amount of characters because from his perspective he hasn't. I also can't set the database field to the worst case scenario (being 3 times my max amount).
We are sending an HTML encoded string in the Query string. It was working fine on IIS 6 (windows 2003). We have recently moved the website to Windows 2008 (IIS 7.x). Since the move any Query String that contains "+" sign i.e., "%2b" gives error on the server "404 -File or directory not found."
Another beginner question, I'm afraid... I was wondering if someone could tell me the easiest and most efficient way of getting the fully qualified domain name (e.g. www.google.com) from a UrlEncoded string in ASP.Net (C#).For example: http%3A%2F%2Fwww.google.com%2Fsearch%3Fq%3Dsome%20things%20i%20searched%20forWould give me: www.google.com(Or basically anything where I can check the domain to make sure it's correct.)I'm guessing the first step might be to UrlDecode, but since this is how I'm getting the string, I thought I'd mention it incase it's easier Encoded.

I am using a third party Web Service. I am passing a string to a function in that service, that string, which i am reading from a UTF-8 text file. The problem it that the string contain some non ASCII characters.
Now if i save that text file to ANSI format, read it in a string and pass that string to Service then it works smoothly but with UTF-8 encoded string the service throw exception [Code]....
NON ASCII characters UTF-8 encoding SOAP
I am using ASP.NET.
Third party sevice is in java. I also tried it by making a web service in .net, but there was issue there too.
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 am really struggling deserializing a PHP json encoded string in ASP.NET.I am using nusoap and CakePHP 1.3 on the PHP side and mvc.net 4.0 on the web service side and everything was working well. However, I couldn't figure out how to pass a complex array as one parameter of the webservice, so I had the idea of serializing it as json and passing a simple string. So far so good...
I have a checkbox on a templatefieled named chkbxlate. I want to write code to check a checkbox or all the checkboxes on that column if the system time is greater than 9:30am during roll call but I don't know how to go about it.
I have tried using .NET's various encryption functions but all my encrypted strings are at least 24, 28 or 32 in length.
I have heard of CipherMode.CTS with Padding = None that produces the same length output as the input length but I can't seem to get the same result. I have toyed with the block-size, key-size and salt size.
I don't mind adding a digit to my input string to make it 16 in length.
Passing onto a stored procedure a value from a GridView. The particular fields are a date type, and numeric type. Problem is, its plausible and conceivable in this case one or both could be null or empty.
Through searching I've seen suggested such ideas as Convert.ToDate(value), CDate(value), and so on. None of these work. You cannot convert an empty string or null value to a date. I don't know about the numeric value.
So, barring any non-working examples already given. What is standard. Its not like I've stumbled across some never afore seen problem.
Here is my code, but its quite typical.
Dim txtctlHireDate As TextBox = CType(gvEvaluatees.Rows(e.RowIndex).FindControl("txtHireDate"), TextBox) Dim txtctlGradYear As TextBox = CType(gvEvaluatees.Rows(e.RowIndex).FindControl("txtGradYear"), TextBox) Dim txtctlBU As TextBox = CType(gvEvaluatees.Rows(e.RowIndex).FindControl("txtBU"), TextBox) Dim ddlctlEvalGroups As DropDownList = CType(gvEvaluatees.Rows(e.RowIndex).FindControl("ddlEvalGroupSelection"), DropDownList) Dim chkctlActive As CheckBox = CType(gvEvaluatees.Rows(e.RowIndex).FindControl("chkActive"), CheckBox) UpdateEvaluatees.MGEvalUpdateEvaluatee(gvEvaluatees.DataKeys(0).Value, txtctlHireDate.Text, txtctlGradYear.Text, txtctlBU.Text,ddlctlEvalGroups.SelectedValue, chkctlActive.Checked) gvEvaluatees.EditIndex = -1 gvEvaluatees.DataSource = EvaluateesForDataGrid.GetData gvEvaluatees.DataBind()
I've bolded the parameters in question. A date value and numeric value are expected.

I have a label control in datalist. When thw word is long, the text of label corrupts the design. Label hasn't a multiline property.I tried different ways .
