Application("TipNumber") = 1
If Application("TipDate") <> Today() Then
Application("TipDate") = Today()
If Not IsNumeric(Application("TipNumber")) Then
Application("TipNumber") = 1
Else
Application("TipNumber") = Application("TipNumber") + 1
End If
End If

Dim cmd As SqlDataAdapter = New SqlDataAdapter("Select Thought From Thoughts_Tbl " & "Where id = " & Application("TipNumber"), Con)
cmd.Fill(_dataSet, "TheTip")

If _dataSet.Tables("TheTip").Rows.Count = 0 Then
Application("TipNumber") = 1
cmd = New SqlDataAdapter("Select Thought From Thoughts_Tbl " & "Where id = " & Application("TipNumber"), Con)
cmd.Fill(_dataSet, "TheTip")
End If

lbl_Title1.Text = "Thought of the Day :"
lbl_ThoughtText.Text = _dataSet.Tables("TheTip").Rows(0).Item("Thought")

This is the actual code where i'm check the date with today's day if it matches and the TipNumber is not numeric it wil take first statement Application("TipNumber") = 1 or if TipNumber is numeric i.e having some number, it wil be incremented in else part Application("TipNumber") = Application("TipNumber") + 1
but TipNumber which is incrementing is not saving? Now how to save TipNumber n incrementing it and get the next "TipOfDay" from database?

Pls help me with some solution

Having this Data in the Application Variable is pointless. Application_Start Event is not meant for this. This will not serve your purpose.

Why don't you have a Date Column to the Thought's Table and fetch the Tip based on the Date. I think this would be the appropriate solution to the given problem.

You need to persist the value somewhere, ie a database, along with the datetime it was written. Then, perhaps in an onsession event, read this value from the database, compare the date it was written with 'todays' date, and update if necessary.

If you don't persist the value, if you site ever goes down, or you modify the webconfig, or the process gets recycled for any reason, you will lose this value.

Step 1: On the Page Load Event, Populate the First DropDown.
Note: In Page Load Event Add (IF Not Page.IsPostBack) and write the code in it.
Step 2: Enable the PostBack Property of the First DropDown
Step 3: On the SelectedIndex Change of the First DropDown, write the Code to Populate the Second DropDown by passing the Selected value of the First Drop Down.

Dear John
Thanks for your instruction,
Problem is, if selected index change from FIRST DDL then refreshing the whole page.
Only SECOND DDL will refresh not whole page.
thanks

Do you mean that you want avoid the Page Postback while Populating the second DropDown? If yes, try to implement AJAX which will send a request to the server and do the task without posting your page.

hi,

In my appication i'm using Oracle as a back end. In that when i'm using ExecuteReader() it shows an exception. Can any one of help me to solve this issue.

<br />
oleDBConnection = new OleDbConnection(connectString);                   <br />
                    string query = "SELECT V_FIRST_NAME,V_LAST_NAME,V_PHONE_NUMBER,V_EMAIL,V_FAX_NUMBER,V_ADDRESS,V_TITLE,V_POSTAL_CODE,V_COUNTRY from UserDetails where (V_USER_ID = ?) AND (V_PASSWORD = ?)";<br />
<br />
                    OleDbCommand oledbCmd = new OleDbCommand(query, oleDBConnection);<br />
                    oledbCmd.CommandText = query;<br />
<br />
                    oledbCmd.CommandType = CommandType.Text;<br />
<br />
                    OleDbParameter par = oledbCmd.Parameters.Add("UserName", OleDbType.VarWChar, 50);<br />
                    OleDbParameter parm = oledbCmd.Parameters.Add("password", OleDbType.VarWChar, 50);<br />
<br />
                    oledbCmd.Parameters["UserName"].Value = userName;<br />
                    oledbCmd.Parameters["password"].Value = password;<br />
<br />
                    oledbCmd.Connection = oleDBConnection;<br />
<br />
                    oleDBConnection.Open();<br />
                    <br />
                    OleDbDataReader dr ;<br />
                    dr = oledbCmd.ExecuteReader();<br />

It threw an exception when executing the last line. The exception states that Unspecified error.Oracle error occured,but error message could not retrieved from Oracle.Data Type is not supported.

Dear All,
I have a web application (ASP.NET / framework 2.0 / Windows Server 2003) on one machine, i.e. Web Server and corresponding database (SQL Server 2005) on second machine.
If I access the application from Web Server, it works fine, but when I access from a third client machine it gives following error
-------------------------------------------------------
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Data.SqlClient.SqlException: Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.
-------------------------------------------------------

I think this has some thing to do with the permissions to access DB from client machines

my Web.config file has following things added
---------------------------------------------------------
<add name="ConnString" connectionString="workstation id=MY_WORKSTATION;packet size=4096; integrated security=SSPI;data source=MY_DB; persist security info=False;initial catalog=MY_CATALOG"/>
<system.web>
.....
<identity impersonate="true"/>
.....
</system.web>
---------------------------------------------------------

Moreover, the SQL Server is configured as per following link
"http://support.microsoft.com/kb/914277"

Please guide

How to close a frame from either javascript or from code behind in a page? Suppose if in a page two frames are present and in one frame an aspx page is present...in onClick of a button in the aspx page the other frame should be closed and the aspx page should occupy the whole window ...is there any way to do this?

I guess you can't close a frame. You can redirect to other page which don't have any frames.

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia

Why reading it from the text box again? Just do:

URL = "http://" + URL;

makhaai wrote:
string ConvertURL =(string)Cache.Get(URL);

Why do you look in the cache for the source? Do you have any code elsewhere that stores anything in the cache?

You forgot to dispose the HttpWebResponse and the StreamReader.
