guys;
i have 2 request the first is post used to add cookies to response the other is a get request caused by Request.Redirect() call in the first one's server side.

my expectation is to find the added cookies in the second's request cookies, but what really happens is that the added cookies disappear.

please help me with this as i am stuck.

You should post the relevant code.

There are only 10 types of people in the world, those who understand binary and those who don't.

Sir;
Thank you for trying to help.
The reason for cookies disappearing was, that I was mistakenly assigning a domain for the response cookies in the post request other than the actual domain, so they wont appear in the redirect request.

Help people,so poeple can help you.

I need to compare 2 tables to find (List) the difference. How would I do this?

modified 18-Aug-14 13:46pm.

Sql tables? DataTables? Difference in columns? Difference in data? Need a lot more information.

There are only 10 types of people in the world, those who understand binary and those who don't.

try

C#

class Program
  {
    
    static void CompareList<T>(List<T> a, List<T> b, ref List<T> diff)
    {
      foreach(T item in a)
      {
        if(!b.Contains(item))
        {
          if(diff.Count == 0)
          {
            diff.Add(item);
          }
          else if(!diff.Contains(item))
          {
            diff.Add(item);
          }
        }
      }
    }

    /// <summary>
    /// Compare Two Lists of primitive types and return sorted list
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="a">The first list to compare</param>
    /// <param name="b">The second list to compare</param>
    /// <param name="diff">the ref param that returns the sorted list of items not in both lists</param>
    static void ListDifference<T>(List<T> a, List<T> b, ref List<T> diff)
    {
      CompareList(a,b,ref diff);
      CompareList(b,a,ref diff);
      diff.Sort();
    }

    static void Main(string[] args)
    {

      List<int> a = new List<int>{1,2,3,4,5,6,7};
      List<int> b = new List<int>{4,6,7,8,9,10};
      List<int> diff = new List<int>();

      List<string> c = new List<string>{"a", "b", "c", "d","e", "f", "t", "U"};
      List<string> d = new List<string>{"b","e","f","g","h"};
      //List<string> d = new List<string>();
      List<string> diff2 = new List<string>();

      ListDifference(a,b, ref diff);
      ListDifference(c, d, ref diff2);

      Console.WriteLine("-- Result of CompareLists for Int");
      foreach(int i in diff)
      {
        Console.WriteLine(i.ToString());
      }
      Console.WriteLine();
      Console.WriteLine("Results for CompareLists for strings");
      foreach(string s in diff2)
      {
        Console.WriteLine(s);
      }

      Console.Read();
    }
  }

Hi,

I want to download multiple pdf files in a single button click. I am using an open source dll, Ionic.Zip.Reduced.dll.
All code runs with out showing any errors or exceptions. By using Response.End(), I am getting a response in firefox's firebug window but when I use it in my application it throws an exception and not showing any download dialogue box. So, I had changed it to HttpContext.Current.ApplicationInstance.CompleteRequest();. Now the exception is gone, but I am not getting any response and dialogue window to download. When I debugged, I found something like this
:ClientDisconnectedToken = 'context.Response.ClientDisconnectedToken' threw an exception of type 'System.PlatformNotSupportedException'
:base {System.NotSupportedException} = {"This operation requires IIS version 7.5 or higher running in integrated pipeline mode."}

What is the real problem here, I could download files in zip by using the same code for a new project.

Please help me to sort this out. Here is my code:

System.Web.HttpContext context = System.Web.HttpContext.Current;
using (ZipFile zip = new ZipFile())
{
zip.AlternateEncodingUsage = ZipOption.AsNecessary;
zip.AddDirectoryByName("PDFs");

foreach (string item in FilePaths)
{
zip.AddFile(item.ToString(), "/PDFs/");
}
context.Response.Clear();
context.Response.BufferOutput = false;
//context.Response.Buffer = true;
context.Response.ClearHeaders();
context.Response.ClearContent();
string zipName = String.Format("Zip_{0}.zip", DateTime.Now.ToString("yyyy-MMM-dd-HHmmss"));
context.Response.ContentType = "Application/zip";
context.Response.AppendHeader("content-disposition", "attachment; filename=" + zipName);
zip.Save(Response.OutputStream);
//Response.Redirect("www.google.com", true);
context.Response.Flush();
context.Response.SuppressContent = true;
context.ApplicationInstance.CompleteRequest();

//Response.End();
}

Thanks in advance

Isn't this a programming related question?

I'm trying to insert record into microsoft access database using the above code in asp.net. But the error specified above occurred and my connection string is ok. When i used same code in windows application, it works fine. Please help.

Don't you need spaces in your sql statement? ie
insert into tbl1(names) values(@names)
should be
insert into tbl1 (names) values (@names)

Thank you very much. It worked perfectly

If this is an MS Access database then the word names is a reserved keyword. You need to use square brackets around it to use in a query.

C#

"insert into tbl1([names]) values(@names)"

That depends where the data is being stored at.

The only thing to do is, to first check for any match in the data. Forexample, if it is a database related data then alteast first check for any row that has the same data as

SQL

"SELECT * FROM table_name WHERE column_name = value";

If there is a result, then don't save it. If there is no data for this query (no result) then save it.

There are other methods for saving data too, like JSON and XML files. Same algorithm works, you first check whether the data is present or not, and then do what's required, save it or not! General logic would be

C#

if(data == "present") {
   // data present
   Console.WriteLine("Data present! Thanks");
} else {
   // save the data to database or the location,
   Console.WriteLine("Data saved! Thanks");
}

Hi,

You can use bellow mentioned SQL Statement in your Stored Procedure / Query.

IF NOT EXISTS (SELECT <COLUMN NAME> FROM <TABLE NAME>)
BEGIN
"YOUR INSERT INTO SQL QUERY"
END
ELSE
BEGIN
"YOUR UPDATE SQL QUERY"
END

By this way you will handle duplicate insertion.
Hope this will help you.

Thanks,
Nishant Raval.

You can check it in your c#, javascript, SQl codes. Where exactly you need that validation ?

You can put a JavaScript function in the WorkingPanel.aspx page that you can then call from the main page.

Your button, btnRSend has CausesValidation set to False which means when it is clicked the validators will not fire.

Hello Experts,

We are building an app that allows users to make online reservations of our facility.

The code below is designed to allow users to perform a search by either specific date or by date range.

Users can also search by selecting a search option from the dropdownlist.

The way the code works currently, if user's search turns up nothing, then we get the following error message:

Object reference not set to an instance of an object.

Line 259: Dim lblcurrentpage As Label = DirectCast(gvrow.Cells(0).FindControl("CurrentPage"), Label)

Rather than the error message, w would like the code to work differently.

If user's search is successful, the results of his/her search is displayed.

If however, no data is found based on his or her search parameter, we would like to display one month's worth of results.

Is this possible?

Below is the current code we are using.

PHP

Private Sub showGrid()
    ' Set the value of the SearchString so it gets
    SearchString = txtSpecificDate.Text
    ViewSelect = Request("ViewBy")

    If ViewSelect = "" Or ViewSelect = "Range" Then
        ViewSelect = "Range"
    Else
        ViewSelect = "Specific"

    End If
    'Response.Write(ViewSelect)

    'Protect against SQL Injection
    strSearch = Replace(receiveddate, "'", "''", 1, -1, 1)
    fromdate = Replace(fromdate, "'", "''", 1, -1, 1)
    enddate = Replace(enddate, "'", "''", 1, -1, 1)

    receiveddate = DateTime.Today.ToString("MM/dd/yyyy")
    fromdate = DateTime.Today.ToString("MM/dd/yyyy")
    enddate = "12/31/2050"
    ' first: Do we use AND or OR between clauses in the WHERE?
    Dim andors As String = ANDOR.SelectedValue

    'Response.Write(andors)
    'Response.End()

    ' and now build up the WHERE.

    'First, initialize where just to make sure it has nothing prior to our search
