i am assigning the value in session variable but it is getting null when i am checking.
suppose i have two link button and when i am clicking the link button then i am assigning some value in session variable
but when i am checking again when link button is clicked then found value null.
my code is
protected void LinkButtonClick (object sender, EventArgs e)
{
if (Session["Download"] == null || (int)Session["Download"] == 0)
{
Session["Download"] = 1;
processLogTask();
}
else if ((int) Session["Download"] ==1)
{
//system is busy
}
}
protected void processLogTask()
{
//when routime will be finished
Session["Download"] = 0
}
so when first time click on link then LinkButtonClick event will be fired and i put some value in session and
processLogTask()
routine will be called and it will take long time to finished.
basically i design in this way when user click on link button processlongtime will be called so if same user click again
on linkbutton then processlongtime will not be called if processlongtime routime is still running. but here i have seen
that when first time user click the session variable is assigned with 1 but when user click immediately the link button
again then session variable value found null. why session variable value is getting null whenever it is already assigned.
please help how to solved this session problem.tbhattacharjee

I think somehow your session value couldnt be stored properly. This is weird. Can you check this directly using
HttpContext.Current.Session ?
|
|
|
|
|
as you mention that your process will take more time then it might possible that your session is timeout and session will be clear.
check the session time out in your web.config file and increase it depends your process time. it may resolve your problem.

I have installed "aspnet_regsql" at the command prompt as follows:
aspnet_regsql -S <servername> -E -ssadd -sstype p
After that, I have made changes in the Web.Config file as follows:
<sessionstate mode="SQLServer" sqlconnectionstring="Data Source=myServerName; Integrated Security=true" cookieless="false" timeout="20">
After that, I have made one small asp.net application in which there is one default.aspx web page in which there are following tools:
And code for default.aspx.vb is:
Partial Class SessionState
Inherits System.Web.UI.Page
Sub Session_Add(ByVal sender As Object, ByVal e As EventArgs)
Session("mySession") = text1.Value
span1.InnerHtml = "Session data updated! <P> Your session contains: <font color=red>" & Session("MySession").ToString() + "</font>"
End Sub
Sub CheckSession(ByVal sender As Object, ByVal e As EventArgs)
If Session("MySession") <> Nothing Or Session("MySession") <> "" Then
Dim strSession = Session("MySession").ToString
If strSession.Equals("") Or strSession.Equals(Nothing) Then
span1.InnerHtml = "NOTHING, SESSION DATA LOST!"
Else
span1.InnerHtml = "Your session contains:<font color=red>" & Session("MySession").ToString() + "</font>"
End If
End If
End Sub
End Class
Now, When i run the applcation , sessions are stored properly in the "AspState" DataBase.
But when i restart the application, sessions are not shown on the page but are still in the database.
In other words, session state works like In-proc , even is used with SqlServer mode.
Where colud be the error..?
Plz help

Will master page build in visualstudio 2008 express edition gets changed when the page is opened in visualstudio 2008 professinal edition?
I had created a sample master page in visualstudio 2008 express edition and when I opened the same website on other PC to work on it, I had observed that that alignment of <div> tags gets changed in the masterpage. Why this is happening?
Can anyone suggest something to solve this?
|
|
|
|
|
Actually Express Editions has less no of options that Professional edition have.
Just dont change the code to Professional edition, rather try to run the same html code to the professional edition. I think if the html remains same, it will render the same in both the editions.

You can do it in 2 ways..!
1)while retrieving the query append ID+Gender to one field wit separator and add it to DataValueField ,split the data value field you will get Id and Gender ..
2)Otherwise with the help of Id

I have a .Net Application in C# which connects to an Oracle 10g R2 database, but when the application is running and it is accessing the database more and more sessions are being created and opened. This happens until the application crashes and no one can access the database.
Checking the database using a query in SQLPlus and looking at v$Session, I can see a large number of open sessions. This is despite the application opening and closing connections to the database.
Therefore, I looking for a solution which I can either pool sessions, i.e. users can use them and hand them back, or can close them after unloading a page, or something else.
Can someone help me, please

Right Im starting to look at web programming and need a bit of help.
And im starting at the deepend, I was looking at a tutorial on this site for an Ajax style chat program. In the code it uses javascript callbacks to log the user out. Wrapping my head around the way the client calls the server and the program responds was difficult and I want to see if I have this right.
These are the two java script functions I am using. The LogMeOut function get called on a button click.
function LogOutUser(result, context) {
alert("test")
alert(result)
}
function LogMeOut() {
LogOutUserCallBack();
}
and here is how they are registered.
string callBackReference = Page.ClientScript.GetCallbackEventReference(this, "arg", "LogOutUser", "", false);
string logoutScript = "function LogOutUserCallBack(arg, context) { " + callBackReference + "; }";
Page.ClientScript.RegisterClientScriptBlock(typeof(Page), "LogOutUserCallBack", logoutScript, true);
So let me see if I have the logic for this right.
The callback reference going to create a call to the server side ICallbackEventHandler.RaiseCallbackEvent
using the client side WebForm_DoCallback function. And the LogOutUser function is the resultHandler.
The RegisterClientScriptBlock and logoutScript just add the function which wraps the WebForm_DoCallback reference to the client page.
The format for the clientCallback function has to be func(result, context).
of which the value of result is the value passed back from the server function ICallbackEventHandler.GetCallbackResult().
I think I have that figured out correctly but I have a few question remaining, as well as a problem.
I have a problem with the "alert("test")". when I run the program no alert pops up. But If I debug through it with FireBug it does ! Im fairly it get called when not debugging but not sure why the alert doesnt get called. And my breakpoint on the same line in Firebug doesnt get called !
The next question is basically my lack of understanding of the whole system and the role that WebResource and ScriptResource axd files play. Are these just two large file that the client has to download with the aspx page to get the page to run AJAX ? or how are these managed ?
I know this is a lot but I would really appreciate a bit of guidance.
Many Thanks

Hello All,
I found the article on SearchableGridView to be most helpful because it functions exactly how my client wants it. I converted the C# code to VB and created a new class file in my web application, naming it SearchGridView.vb. I inserted the converted code, referenced the namespace in web.config and added an import namespace to my content page.
Unfortunately, I receive the following error:
Warning 1 Namespace or type specified in the project-level Imports 'MyApp.WebControls' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases. DielWebProj
Here's the first bit of SearchGridView.vb:
Imports System
Imports System.Collections
Imports System.Collections.Generic
Imports System.ComponentModel
Imports System.Text
Imports System.Web
Imports System.Web.UI
Imports System.Web.UI.WebControls
Imports System.Drawing.Design
<Assembly: TagPrefix("MyApp.WebControls", "SearchGridView")>
Namespace MyApp.WebControls
#Region "TemplateColumn"
Public Class NumberColumn
Implements ITemplate
Public Sub InstantiateIn(ByVal container As System.Web.UI.Control) Implements System.Web.UI.ITemplate.InstantiateIn
End Sub
End Class
#End Region
<ToolboxData("<{0}:SearchGridView runat=server></{0}:SearchGridView>")> _
<ParseChildren(True, "SearchFilters")> _
Public Class SearchGridView
Inherits GridView
Can anyone identify where I've gone wrong? How do I rectify this issue?
Thanks,
Sid

No, I've checked this for you
