VS 2008 Global Variable In Web Service?
Jan 16, 2010
I am having some trouble with my web service. I want to make a variable that will be the same for each thread running. To be specific, my program is that user 1 goes on my page and types something into the textbox and that user 2 can see what user 1 is typing into the box. its sorta like google wave. The problem is that when i run it, the variable's value does not go to user 2 and instead another instance of that variable is created.

I have a JavaScript wrapper that I initialize on body load and set to a global variable.
Just after creating the object, I have full intellisense, but when referring to it later, from another function, the intellisense is lost. I presume this is because of dynamic typing:
var myWrapper;
function onload() {
myWrapper = new Wrapper(args);
myWrapper. //intellisense here.
}
function whatever() {
myWrapper. //intellisense lost.
}
I get round this by pretending to create the object again before my code, and then deleting the line:
function whatever() {
myWrapper = new Wrapper(); //pretend to create object again.
myWrapper. //intellisense returns!
}
Has the inference been improved in vs 2010, or is there any way to tell Javascript about the type of object I'm currently working on?

I know there is a couple answered questions on here regarding "request scoped" globals, but I want to nit-pick on something specifically and maybe squeeze some extra enlightenment out of one or two of you.I have an ASP.NET C# Website and a static Dictionary of objects (loaded from DB once on Application start). Each page request will need to do a lookup in the Dictionary (based on a key derived from the request url/etc) and get the appropriate object.The issue is I'm trying to maximize efficiency by reducing the lookups to the Dictionary per Request. Doing just a single lookup within a Page itself is easy enough and I can pass the object to sub controls, etc too.. but global.asax is separate from the Page and it also needs to use the object (in Application_BeginRequest and Session_Start).
So is doing a Dictionary lookup once in Application_BeginRequest, once (when necessary) in Session_Start and once in the Page negligible speed wise, even if there are many requests coming in every second?I would like it if I could just have a Request scoped global variable that I can easily call upon.. the only one I see available though is HttpContext.Current.Items and that is a Dictionary itself.Am I beingridiculously nit-picky with my concern over efficiency? or will these milliseconds (nanoseconds?) get me in the long run when more and more requests are being made?
PS. I currently only have around 100 objects in the Dictionary although this may increase in the future.

I have the dataset. in this i am having total 20 tables with huge amount of data..I want use this data over all the page..so where i can keep this data..
before i used viewstate but the viewstate data is render to page every postback ..so this time the page size is increasing(interanlly viewstate is rendered to page)..so performence wise it was very slow..
Now i change my logic insted of viewstate to i used Globel Dataset on Page Level.. now the performence wise better than viewstate..
i used Like shared dsControls as Dataset at top of the page..so every time i use this dataset..
my quesation is session is better or Globel variable is better way use in my situavation..

Is it possible to use global variables in C#? I'm coming from mainly a PHP background so variables are either accessible everywhere or just a global definition away.
My main issue is I have a User class that I built myself to wrap around the current users table on my company's database. I am defining it in the MasterPage but can't seem to access it from the actual pages (I don't know if there's a better word to describe them but they are the pages that inherit the styles and format from the MasterPage) Any general tips or implementation practices for me?
EDIT: here's some code snippets of what I'm trying to do:
Site.master.cs
public partial class SiteMaster : System.Web.UI.MasterPage
{
public User user = new User();
}
logout.aspx
<%@ Page Title="" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeFile="logout.aspx.cs" Inherits="logout" %>
<%@ MasterType virtualPath="~/Site.master"%>
logout.aspx.cs
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
User user = Master.user;
}
}

I have a process within my MVC 2 application that takes a large amount of time and alters many rows in the database in the process.
There is a chance that two or more users could attempt to perform this action at the same time, which would lead to undesirable effects.
Is there a way to set a global flag somewhere within asp.net that I can check against all requests to see if the action in question is currently being executed? (a bit that I flip prior to running query, and then then flip back on completition)Or is there a better way of handling this situation?

I'm pretty new to silverlight and asp.net but I have a strong background in c#. I am currently developing a c# asp.net application with silverlight elements. I was wondering if it was possible to have a user say click on an image that has a certain value associated with it and have that value access from a c# variable held outside the silverlight application.

I want to declare a Dictionary<string, object> variable but don't know where/how to. The values in the dictionary will be objects from the Page (ListBoxes, DropDownLists, etc) so I can't exactly create a class somewhere else. Is there any way I can make this variable accessible from each method in the codebehind?

I would like know how to declare a global variable that can be used within a user after the user login and before the user logout across all the possible pages.
I need to develop a web application that will connect to 5 different servers depends on the selection of user on what server they wish to connect and after they select a server and login...I will need to keep track the server name in a variable last until the user logout (user may visit various pages but the server name MUST NOT be changed due to other user login into different server). So how can I do it so that other users may select different servers and will keep the server name for each different users.
Let says:-
User A selects Server A and login and User B selects Server B and login at the same time, so how the global variable can handle the needs for each user (User A & B) with different server select?
Is "Session" the only way to fulfill the above? I think of using Application State but it seems that the value stored will be shared by all users and not for a particular user.

I need to use a global variable as a parameter for the SqlDataSource element. I capture the user Name when he/she logs in:
Public UserName As String
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
UserName = Page.User.Identity.Name
End Sub
Then, I need to use the UserName to search the SQL DB and show only logged user personal information.
SelectCommand="SELECT * FROM [Member] where [UserID]= UserName"
What is the sintaxe to use a global variable into the SQL Select Command?

I'm looking for a way to declare a global variable (so all pages could see) but personal (so if one user puts some value in it, it won't matter to another user or change his value).Sessions and hidden fields won't do. I've tried working with declaring keys in Web.config but unfortunely, the keys values aren't personal, and all users share the same key value.Another way I was thinking was maybe classes, but perhaps there might be an easier solution?

I have a ASP.NET/C# web application. There is an object instantiated in the Global.asax that I'll call g_objVariable. What I would like to do is reference one of it's properties in the ASP.NET page itself, like this.
The g_objVariable's Prop1 value is: <%=AppNameSpace.Global.g_objVariable.Prop1.ToString()%>
I get it to see the reference, but it keeps telling me that due to it's protection level I can't access it. I have it set to 'internal static'. What would be the least level I could set it to, but still allow the page to access it?

I am looking for differences between those 3 ways of using static class in asp.net application scope.
Will all of these point to the same class?
Which one is preferable >object< defined declaratively inside global.asax or static class ?
examples:
<object runat="server" scope="application" class="classname" ID="objID"></object>
VS
public static class classname {}
VS
Application("a") = new classname();

I'm getting a very peculiar problem with my asp.net application, it took me an age to track down but I still don't know what is causing this behaviour.
If I set a session variable in the Application_PreRequestHandlerExecute event, then my external JavaScript files are ignored, and therfore causing a raft of errors. I have simplified the problem below.
E.g.
I have file called JScript.js containing the code:
function myAlert() {
alert("Hi World");
}
And in my Default.aspx file I reference the js with the code:
<script src="JScript.js" type="text/javascript"></script>
And in the body onload event I call the myAlert() function:
<body onload="myAlert()">
And finally in the Global.asax file:
Private Sub Application_PreRequestHandlerExecute(ByVal sender As Object, ByVal e As EventArgs)
HttpContext.Current.Session("myVar") = "MyValue"
End Sub
If you run the Default.aspx file you will see the js function isnt called, however, if you comment out the line of code Global.asax then the external js is called and the function executed when the page loads.
