Hi..
I know how to use the application and session state variables and i have used the following code :
(In the Global.asax 
protected static int m_ActiveUsers;
public static int ActiveUsers
{
get
{ return m_ActiveUsers;
}
}
protected void Application_Start(Object sender, EventArgs e)
{
Application.Lock();
m_ActiveUsers=0;
Application.UnLock();
}
protected void Session_Start(Object sender, EventArgs e)
{
Application.Lock();
++m_ActiveUsers;
Application.UnLock();
}
protected void Session_End(Object sender, EventArgs e)
{
Application.Lock();
--m_ActiveUsers;
Application.UnLock();
}
But the problem it doesnt give me the right number always.Some times this code tells me there is two visitors while there is no one except me.And some times it doesnt decrement the visitors count number when i exit.
Do any one know how to make a better way that wont be affected by application errors and will solve my problem?

In global file
at application start
application("users") = 0
at form loads
Application("users") = CType(Application("users") , integer) + 1
label1.text = Application("users").tostring

Your code will count how many times users load the webform not how many users visit the website?!
"I am too late but i will never give up"

this is code is not right .
suppose currently 4 user are active and one of 4 user quit and again he comes back for him session will start form begining and session_start function calculate m_active user to 1 so it will give wrong result.
better is that maintain this variable m_active user in some file or database and increment and decrement it when user starts and end session.
hope this will work

Thank you for your respond...
You said :and session_start function calculate m_active user to 1
As i know when a user quits and returns this will not restart the whole web application(Application_End) but will restart only one of the four users sessions(Session_End).I mean ending one session will not end other 3 sessions.

Hi
I have a dropdown list with all the hub groups. When a hub group is selected, it loads and displays all the hubs for that hub group.
In my apsx code I have defined an empty table as follows:
<asp:Table id="tblHubCommRates" BorderWidth="0" Width="100%" runat="server">
</asp:Table>
When the hubs are loaded, I dynamically create the row, the cell, and the textbox. The textbox is called txtHub1, or txtHub7, depending on the hub ID from the database. The can be many hub for a selected hub group. Thus, many rows and may text boxes.
I would like to iterate through these dynamically generated textboxes to get there names, and the values in the textboxes.
When I do the following iteration (on 2 textboxes that were created):
foreach (Control c in this.tblHubCommRates.Controls)
{
Response.Write(c.GetType().ToString() + "<br>");
}
...it prints
System.Web.UI.WebControls.TableRow
System.Web.UI.WebControls.TableRow
I'm assuming the parent control is the table row's cell. But how do get the value of the textboxes in the cells?? Please can someone advise??
Regards,
ma se

I don't know why you are doing it this way instead of using a datarepeter or gridview but...
The table has a collection of TableRows, the TableRow has a collection of tableCells the TableCell has the textbox.
Try something like this...
private void TextboxValues(System.Web.UI.Control cntrl)
{
if (cntrl.GetType() = typeof(TextBox))
{
TextBox t = (TextBox)cntrl;
Response.Write(t.Text);
}
if (cntrl.HasControls)
{
TextboxValues(cntrl);
}
}

how to convert sql database into xml form in asp.net + c#.
Please give me some links.
Thanks in advance .

Hi,
You could use this stored procedure to convert the SQL Tables into xml
sp_makewebtask
You can have a look at this procedure from SQL books online.
Also you can export the contents of datatable using the code.
First you have to create a typed dataset, and then you fill the contents to the datatable in the dataset and then use the method
dataset.writexml to fullfill your requirement
Hope i have helped you out,
Happy Programming

Hi
I am having difficulty with a Web Application that does not seem to close or release a Sql Server database connection. I am using Visual Studio 2003 and SQL Server 2000.
I am using the following data access method:
public static void LoadData(string connectionString, string procedure)
{
SqlDataReader reader = null;
SqlConnection conn = null;
try
{
conn = new SqlConnection(connectionString);
conn.Open();
SqlCommand sqlCmd = new SqlCommand(procedure, conn);
sqlCmd.CommandType = CommandType.StoredProcedure;
reader = sqlCmd.ExecuteReader();
while (reader.Read())
{
}
}
catch (Exception e)
{
throw e;
}
finally
{
if (reader != null)
{
reader.Close();
}
if (conn != null)
{
conn.Close();
conn.Dispose();
}
}
}
After I have run my Web App and closed it, I went to Query Analyzer and tried to drop the database (the database only has one table and I am just using it to test). It gives me the following message:
Cannot drop the database 'TestDatabase' because it is currently in use.
When I try the same data access method in a Windows App and try to drop the database afterwards it drops with no problem. So it seems to me that there must be something extra that I have to do to ensure that a Web App releases or closes the database connection.
Any ideas?
Thanks
Kobus

Make the class as IDisposable and call the despose method to close connection
public class MyDB : IDisposable {<br />
public void Dispose() {<br />
Conn.Close();<br />
}<br />
}
Hope this will work

In the finally block, after closing the connection do not call Dispose. Close and Dispose have the same effect. Calling dispose after calling close will create a new connection and try to close it. If you remove the conn.Dispose(); line everything should work fine.
