Need to substring value from DropDownList from position 1 till I reach the first blank character
Example: 'RGWP - West Palm' would be 'RGWP' and 'SBGB3 - Greensboro' would be 'SBGB3'

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:

I have a dropdownlist on my page with dates such as 1/1/2013, 2/1/2013, etc.
Then there is a second ddl.
If the date in ddl #1 is before 1/10/2013 I want to enable ddl #2.
If the date in ddl #1 is on or after 1/10/2013 I want to either disable ddl #2 or hide it (whichever's easier).
Disabling ddl #2 based on the selected date is a new requirement so I am enhancing the existing code. Obviously I want to do this without a postback, but I don't know what is the best way. I am trying to understand what an AsyncPostBackTrigger is because this is the existing code:
Code:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:dropdownlist id="EffectiveDateDropDown" runat="server"></asp:dropdownlist>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="QuoteType"
EventName="SelectedIndexChanged" />
</Triggers>
</asp:UpdatePanel>
It wants to do something when the selected index is changed? This exists in the code-behind, but I set a breakpoint and never hit it:
Code:
protected void QuoteType_SelectedIndexChanged(object sender, EventArgs e)
{
try
{
}
catch (Exception err)
{
this.PublishError(err);
}
}
The following is a line of huge .txt file and i am reading it line by line. I need the value of second column. In this line, I need to extract 'C9006'.
Mr ABC|C9006|The white field,
ON|493-493-4939|493-493-4939|YR|Inactive
Note : The delimiter char is pipe sign '|'. The length of second column is not consistent.
I am binding some data to control, but want to limit the number of character of a specific field to a 30 first characters. I want to do it, if it's possible, on aspx page.

But got this error: Index and length must refer to a location within the string. Parameter name: length

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?
how to find and replace substring in select query

What's the regular expression to check if a string starts with "mailto" or "ftp" or "joe" or...
Now I am using C# and code like this in a big if with many ors:
String.StartsWith("mailto:")

It looks like a regex would be better for this. Or is there a C# way I am missing here?

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

m = Regex.Match(inputString, HRefPattern,
