It is global.asax not global.ajax.

No. Are you referring to the session_start event handler? If yes, it fires when the ASP.NET session starts not when your user logs in.

When user logs in which event will be fired?

No ! Global.asax done his opertaion before that. What do you want ? Do you want to store the session informatio or what ? Please tell your business requirments.

I have a web application which is similar to group management.So every user will belong to one group.When user logs in I need to refer his group related details like group and and also his user related details such as userid,user name and assigned roles for him.Instead of getting these global details in every form,cant I store them in one place (global.asax) and refer where ever i required.If yes please provide the information and problems with it.
Thanks in advance,
Srinivas Mateti

if you want to store the information related to the user then you can do at the same place where User gets login. Just fetch the information from the DB for that user and then store it in a Session.
To store it in a single variable, you can create a simple class. just place the variables that would hold the info required by you. now it's very easy. just create the object of this class, assign values to the variables and then place this object in the session. Now access the session variable at any page .

when user gets login successfully and if you are using FormAuthentication then Application_AuthenticateRequest will be fired but it will be in global.asax not global.ajax. i suppose there was a typo mistake(ajax).

What kind of file Global.ajax is ?  I guess you are asking for Global.asax. if yes, read sashidhar reply.

Hi!
How can I populate a DropDownList by what I select from another?
I have two DropDownLists named Industry and SubIndustry. The SubIndustry DropDownList should display information by what I have selected in Industry.
I have created a Populate_Industry and Populate_SubIndustry methods and I call the SubIndustry_Method by way of the Industry SelectedIndex_Changed event. I have set AutoPostBack="true" on the Industry DropDownList but the Populate_SubIndustry method won't fire.
I have stepped through my code and everything executes perfect but the information does not appear in the DropDownList. I double checked my databind code so I do not think its me not binding to the control.
Please can someone assist? If you want to see the code please reply and I will gladly post it for you.
Thank you!

here is the code:
Variables to check DropDownList State and to get the IndustryId for SubIndustry:
bool LoadSubIndustries = true;
public int IndustryId { get; set; }
Page_Load:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
Populate_Industry();
}
LoadSubIndustries = false;
}
The Populate Methods:
private void Populate_SubIndustry()
{
DataSet dsSubIndustries = lookupManager.GetSubIndsutryByIndustryId(IndustryId);
ddlSubIndustry.DataSource = dsSubIndustries.Tables["Lookup_SubIndustry"].DefaultView;
ddlSubIndustry.DataValueField = "Id";
ddlSubIndustry.DataTextField = "SubIndustry";
ddlSubIndustry.DataBind();
}
private void Populate_Industry()
{
DataSet dsIndustries = lookupManager.GetIndustries();
ddlIndustry.DataSource = dsIndustries.Tables["Lookup_Industry"].DefaultView;
ddlIndustry.DataValueField = "Id";
ddlIndustry.DataTextField = "Industry";
ddlIndustry.DataBind();
}
SelectedIndex_Changed method:
protected void ddlIndustry_SelectedIndexChanged(object sender, EventArgs e)
{
if (LoadSubIndustries == false)
{
IndustryId = (int.Parse(ddlIndustry.SelectedValue.ToString()));
Populate_SubIndustry();
}
}

Steve,
Please ignore. I have found the problem. I have not added the table adapter to my GetSubIndustryByIndustryId method.
Boy do I feel like the idiot!!
Thanks for the quick response!!
Cheers

Have you put a break point on the bolded line:
protected void ddlIndustry_SelectedIndexChanged(object sender, EventArgs e)
{
if (LoadSubIndustries == false)
{
IndustryId = (int.Parse(ddlIndustry.SelectedValue.ToString()));
Populate_SubIndustry();
}
}
to make sure LoadSubIndustries is false? Is it even getting into this event handler? If it's not getting to the event handler, that would indicate the event isn't wired up correctly.

There is no such thing as APS.NET. I get the impression you have no idea what you're doing. That doesn't make for a secure login system. Perhaps you should pay someone to do it for you. Be careful if you decide to list this job on places like rentacoder, because some people advertise on places like that, take jobs they can't do, and post here asking us to do it for them. We tend not to do work for people who are being paid and have no clue.

hello
i find a great article about data access, it is to sql
i change the data access to work with sybase
i change the sql object by sybase object
Protected Overloads Sub ExecuteNonQuery(ByRef cmd As AseCommand, ByRef procName As String, ByVal ParamArray
procParams() As IDataParameter)
'Method variablesoutDim cmd As SqlCommand
Dim cnx As AseConnection = Nothing
cmd = Nothing
'Avoids "Use of unassigned variable" compiler error
Try
'Setup command object
cmd = New AseCommand(procName)
cmd.CommandType = CommandType.StoredProcedure
Dim index As Integer = 0
Do While (index < procParams.Length)
cmd.Parameters.Add(procParams(index))
index = (index + 1)
Loop
'Determine the transaction owner and process accordingly
If _esIniciante Then
cnx = New AseConnection(GetConnectionString)
cmd.Connection = cnx
cnx.Open()
Else
cmd.Connection = _txn.Connection
cmd.Transaction = _txn
End If
'Execute the command
cmd.ExecuteNonQuery()
Catch ex As Exception
Throw
Finally
If _esIniciante Then
cnx.Dispose()
End If
If (Not (cmd) Is Nothing) Then
cmd.Dispose()
End If
End Try
End Sub
when call the function ExecuteNonQuery
Public Function Cliente_obtenerPorCedula(ByRef clienteID As Integer, ByVal cedula As String) As DataSet
Dim cmd As AseCommand
ExecuteNonQuery(cmd, "crm_co_clientecedula", _
CreateParameter("@i_cliente_id", AseDbType.Integer, clienteID, ParameterDirection.Output), _
CreateParameter("@i_cedula", AseDbType.NVarChar, cedula))
clienteID = CType(cmd.Parameters("@i_cliente_id").Value, Integer)
cmd.Dispose()
End Function
everything runs fine until invoke the code cmd.Parameters("@i_cliente_id").Value
ocurr the exception --> Run-time exception thrown : System.ObjectDisposedException - Cannot access a disposed object.
Object name: 'AseCommand: '.
the dispose cause exception
Catch ex As Exception
Throw
Finally
If _esIniciante Then
cnx.Dispose()
End If
If (Not (cmd) Is Nothing) Then
cmd.Dispose()
End If
End Try
the cmd.dispose -->System.ObjectDisposedException - Cannot access a disposed object.
the cnx.dispose -->Parameters {"Cannot access a disposed object.Object name: 'AseCommand: '.
while i comment this line, the code work
'If _esIniciante Then
' cnx.Dispose()
'End If
'If (Not (cmd) Is Nothing) Then
' cmd.Dispose()
'End If
where can be the problem ?
the original code is c# and sql that's work fine
me email is raquidd@yahoo.com
regards
sorry for me english

when you call
ExecuteNonQuery(cmd, "crm_co_clientecedula", _
CreateParameter("@i_cliente_id", AseDbType.Integer, clienteID, ParameterDirection.Output), _
CreateParameter("@i_cedula", AseDbType.NVarChar, cedula))
It will dispose cmd as it is ByRef. So cmd.Parameters will fail. Properties of Disposed object is inaccessible.
