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
"/wEPDwULLTE2OTU5NzE1MjYPZBYCAgMPZBYCAgEPZBYCAgMPZBYCZg9kFgQCBQ8WAh4FVmFsdWUFCGRpc2FibGVkZAIHDxYCHwAFCGRpc2FibGVkZGSt4I2szqsXGPwfecanpFW+cIZNhQ==,/wEPDwULLTE2OTU5NzE1MjYPZBYCAgMPZBYCAgEPZBYCAgMPZBYCZg9kFgQCBQ8WAh4FVmFsdWUFCGRpc2FibGVkZAIHDxYCHwAFCGRpc2FibGVkZGSt4I2szqsXGPwfecanpFW+cIZNhQ=="
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.

I have created web method for "getting contacts".
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 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?

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);
}
?
