I am trying to use substring in c# code.
This is the code i have used:
[Code].... I am getting the error as: "Length cannot be less than zero.
Parameter name: length"} System.Exception {System.ArgumentOutOfRangeException".
I want to get the result 123421, that is after the "\".
I am using Substring method on a string variable.
Code:
fileName.Substring(67, 18)
I get this error
System.ArgumentOutOfRangeException: Index and length must refer to a location within the string.
Parameter name: length
Don't know the reason. I debugged a lot and going crazy about this error.
I have an intranet application which I have been putting together with ASP.NET. I have been using VWD 2010 Beta 2 which has been fine so far. But when I go to deploy the work i've done so far to a local IIS a variable which is supposed to be; being filled with the value from HttpContext.Current.User.Identity.Name is not being filled i.e. an error occurs when substring goes out of bounds. I believe it is because the HttpContext.Current.User.Identity.Name is not putting a value into the string variable 'username'. But it is quite strange as when I run the website project within VWD 2010 it works fine without any errors. IIS is set to Integrated Windows Authentication and Annonomous Users are allowed.
public static String getName()
{
// Store username
String name = HttpContext.Current.User.Identity.Name;
// Truncate username from domain name
String[] substring = new String[1];
// Define the token at which the string will be broken at
char[] token = { '\' };
// Split the string
substring = name.Split(token);
// Return the username
return substring[1];
}
Any ideas why when running the exact same files from local IIS gives me errors?
I need to pull a SubString from a Linq Datasource, but can't use INTs per .SubString(int, int) I have strings such as xxxx.xxxx.xxxxx.AAAA.xxxx.xxxx.xxxx.xxx and I need to pull AAAA out. the preceeding x's will be varying lengths, so I can't use a static int. What I do know is that there will be a static number of periods (.) leading up to the AAAA. I can't figure out how to use the SubSting with characters rather than indexs. This is what I have so far:

Why code <%= System.DateTime.Now.ToLongDateString() %> is not executed in ASP.NET.
<input class="input" name="url" id="url" type="text" runat="Server" style="width: 650px" onblur="this.value='<%= System.DateTime.Now.ToLongDateString() %>'" />
I've read that OnClick is executed on the server and onClientClick is executed on the client. Is it better to use OnClientClick to do something like close a modal popup?
If my understanding is correct then this would avoid a trip to the server to accomplish the same task. This would be great for something that doesn't need to make a round trip to the server and back.

I have a page which allows the user to send email. After they click the submit button, I display a confirmation message. However, if the user clicks the browser's Refresh button once the confirmation message is displayed, the email is sent a second time (or a third, fourth, fifth, etc.). What can I do to prevent the Refresh button from resending the email?

just want to return the first valid email that is found from the input text:

What the heck is line number 939?The Webapplication allows a special user group to change some group memberships for members of another user group in Active Directory. The App handles 3internal DataViews derived from corresponding DataTables as DataSource for 3 GridViews and some other internal lists with objects (List<obj>).
It uses windows authentication to get current users credentials and his membership in the "Operators" group. This credentials will be passed-through to allow the process managing group memberships in active directory.After starting the App in browser it seems to work fine. But after an indeterminated time it doesn't longer respond. After each click on buttons (or link buttons) you only can see the message "Error on Page" in the browsers status bar below.I played with session timeout, storing the DataTables in session variables, without success.
Last week I found this article here: [URL]" and I addedEnableEventValidation="false" ViewStateEncryptionMode="Never"
