Web Forms :: Error - "Invalid Characters In Base64 String"
Sep 15, 2010
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 parameters are UNAME,PWD,VerticalID and Filter, now, there is no problem with my uname,pwd and verticalid, but my Filter have value of A,B,etc.in the sense just one character value.
But whenever I entered data,it returns this error:
"Specified Value has invalid CRLF Characters" this error belongs to Filter.
But when I entered ABCD it returns null because Filter is a string type and only one character value. But ASP.NET is not taking this one character value as string.
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?
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?
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 know that it is basic questions, but I am stuck here.
I have TableOne have fields: USERNAME, PID, GID, TID, SID, NEWSID. I need to write query string to check if those value is already in the table. If not, insert those value to the table.
Protected Sub btnClick_Click(ByVal sender as Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles btnclick.click
Dim sb as New System.Text.StringBuilder() sb.Append("<script language='JavaScript'>launchExecutable('") sb.Append(path) sb.Append(" 2 ") sb.Append("</script>);") ScriptManager.RegisterStartupScript(btnclick, me.Gettype(), "btnclickform", sb.ToString()) End Sub
This is a cut down version of my code, but I'm running this on a TabPanel, so it sets on an Update Panel. If I run this code on a standalone aspx page it works...in other words, without the TabPanel. However, I need it to work on a TabPanel. This is the errors I get: Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: The script tag registered for type 'ASP.client_default_aspx' and key 'btnclickform' has invalid characters outside of the script tags: );. Only properly formatted script tags can be registered.
I have a string with 100 characters and it is for me too long in one line. I want to make NewLine after each 25 characters. For example:
Instead: "Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua."
I've wrote this little method to achieve the goal in the subj., however, is there more efficient (simpler) way of doing this? who will search for this like I did.
var fileName = new System.Text.StringBuilder(); fileName.Append("*Bad/ :, Filename,? "); // get rid of invalid chars while (fileName.ToString().IndexOfAny(System.IO.Path.GetInvalidFileNameChars()) > -1) { fileName = fileName.Remove(fileName.ToString().IndexOfAny(System.IO.Path.GetInvalidFileNameChars()), 1); } ?
I want to show just a part of a string for example:
Instead: "Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua."
Just a: "Lorem ipsum dolor sit amet, consetetur sadipscing..."
I am retrieving time data from database.Its in format of HRS:Min AM. (:,'')are the special charatcters. I need to show Hrs in txtHrs,Min in txtMin,Am/PM in dropdown. How can I do this?
FYI, In databse I have stored dropdown item text, not value.
Now whenever I try to set the selected item using following code, I am getting error System.Web.UI.WebControls.ListItemCollection.FindByText(string)' has some invalid arguments.
I want label to display limited text say 20 char even the data it retrieve from database may be more than 20 char.. like in gmail,we see message body limited when we click it display whole message..how is that possible...?
