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'm passing parameters (over 30 in all) from a system.data.dataset into a tableadapter insert method, but I'm getting an "Input string was not in a correct format" exception.The error points to the method that is throwing, which is great, but is there a way I can tell exactly which parameter is throwing the error?(Sorry about the code formatting -- I fought with it for 5 minutes before giving up)
myTableAdapter.Insert(
row["GUID"].ToString(),
Convert.ToInt16(row["domain"].ToString()),

The send method of SMTP is always throwing an exception. The message is : Failure sending mail Here is my code:
MailMessage mm = new MailMessage();
mm.To.Add("Yuvraj.dhot@xxxxx.co.in");
mm.From = new MailAddress("Kumar.Chaudhari@xxxxx.co.in");
mm.Subject = "Ant Subject";
mm.Body = "Body Cha MEssag here ";
SmtpClient ss = new SmtpClient("localhost");
ss.EnableSsl = false;
try
{
**ss.Send(mm);**
Result.Text = "Message Sent";
Result.ForeColor = System.Drawing.Color.Green;
}
catch (SmtpException ex)
{
Result.Text = "Message Not Sent :
" + ex.Message;
Result.ForeColor = System.Drawing.Color.Red;
}
I also tried using
ss.DeliveryMethod = SmtpDeliveryMethod.PickupDirectoryFromIis;
Now it doesn't throw any exception, it executes fine but receiver does not receive any mail in his inbox. How can I fix this? Edit - This is the stack trace im getting.................
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 "\".
Code:
01.If InStr( Request.ServerVariables("HTTP_REFERER"), "google") > 0 Then
KeyURL = Request.ServerVariables("HTTP_REFERER")
' Remove all up to q=
KeyLen = Len(KeyURL)
kStart = InStr( KeyURL, "q=" )
kStart = kStart + 1
KeyRight = KeyLen - kStart
Keyword = Right( keyURL, KeyRight )

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:

I've got a simple detailsview on a webpage for viewing, adding, and updating inspectors. Since it is a simple details view I'm just used the datasource select, update, delete, and insert commands. When I debug the page it populates the detailsview appropriately and allows me to page through the inspectors but when I try to update a field I'm getting the implicit conversion error in the attached doc. Below is my detail view markup. I was thinking the error is caused by the checkbox type being boolean while the SQL type for "Active" is bit but I've tried to use various conversion methods and can't seem to get them to work.
Code:
<asp:DetailsView ID="dvInspectors" runat="server" AllowPaging="True"

when a user enters a bad email I am doing a check on this and throwing an exception message as follows, this works fine on the test site but for some reason the same code on the live site gives a "internal server error" (http code 500). The code below:

not certain why this is happening, I assume that it's some server or config difference between the test and live sites. has anyone seen this before? For a quick fix i'm registering javascript alert and showing the same text so it works but I would like to figure out why the code above is not working.
I am creating an Asp.net web site which will support dynamic data. When I am creating a dynamic web site from Scratch (from template in VS) all is working fine. But when I am trying to add dynamic entity (.edmx) file and running the application I am getting following error
"The method 'Skip' is only supported for sorted input in LINQ to Entities. The method 'OrderBy' must be called before the method 'Skip'. "
I have the absolutely most simple setup imaginable. A single table defined in an Entity model in ASP.net v4, the model is bound directly to a GridView with AutoGenerateEditButton enabled.However, each time I hit edit, then save, the page throws the error "Update is disabled for this control" for which I cannot find a solution.What is causing this error? What can do to resolve it?
