I need to run some code that will fetch some configuration values from the web.config during first run of an asp.net mvc application. These values will not change frequently but that is not my main concern.
One way that I can think of is calling the method in Application_Start() method in the global.asax.cs file,
I've got a piece of code that I want to run one time when my website is first loaded.It is basically a static initialization of another module.Is there some event I can hook into that runs when the site is first served to a client?It doesn't even need to be per session, just on first load to any client.
I'm using vs2010, .net 4.0, asp.net 4.0
tell me where I could initialize (in the mvc code) the hibernate factory?
View 1 RepliesI have an ASP.NET web-site and a WCF service which is called from ASP. The problem is, that during the first client request the site loads aufully slow, cause some time-consuming static objects are being created inside the WCF service. Is it possible to call any service method (by doing this the wcf object will be created), when the site gets loaded in IIS? (I know there is a solution for this problem in ASP 4 and IIS 7.5, but i'd like to know what's about IIS6-7). It is something like "user emulation") Maybe i can add some event handlers in global.asax?

I am having an Asp.net Web application in .Net 3.5 Framework, deployed on IIS 6.0. Obviously we have used Http Modules in our application. The problem is that we are having many entries specifying the message "Http Module is getting Initialized" Now, I would like to know when does an Http Module get initialized? I mean is there any specific reason? Also, is there any case of recycling of http module?
View 2 RepliesWhen I initialize my client to connect to AppFabric's cache, it seems to inconsistently take up to 30 seconds to connect on the following line:
factory = new DataCacheFactory(configuration);
See full Init() code below - mostly taken from here.I say inconsistently because sometimes it takes 1 second and other times 27, 28 , etc ... seconds. I have an asp.net site using the AppFabric cache - which lives on a different box (on the same domain). Everything is working great, except for the inconsistent connection time. When it connects, its all good - I just need to get it to consistently connect in ~1 second :)
public static void Init()
{
if (cache == null)
{
Stopwatch sw = new Stopwatch();
sw.Start();

We have a silverlight/asp.net application which communicates with WCF to fetch data. Now we are facing a problem where in the silverlight component is taking some time to initialize after the asp.net page life cycle is completed.We have tried tracing all the events and found that there is a time lapse between the aspx page unload event and silverlight initialize event. This we have tried with even a simple application (hello world) but still have found the same result.There is nearly 3-4 seconds delay i.e the silverlight component initialization starts 3-4 seconds after the page unload event ends.
View 1 RepliesI am doing some sorting of an array and in order to achieve that I have to declare bounds of a new array based on amount of results returned. So if I get 2 results I will initialize
tagArray = New Integer() {0, 1}, if 5 then
tagArray = New Integer() {0, 1, 2, 3, 4}. The amount of results is unknown and it can be anywhere from 200 to 500 results returned. Is there a way to simplify this? I could probably hard-code it but that would look ugly.
Our web application started out as a big, honkin' ASP.NET AJAX 'page' with oodles of controls on it. They all shared a small set of large .js and .css files. I need to use some of these controls in other, unrelated pages around our site. The difficulty is in all the other stuff the .css and .js files bring along with them when I try to use those controls elsewhere - too much and there's a lot of bloat, too little and the controls don't work.
So, I've been experimenting with breaking up the .css and .js and writing the controls to register the .js and .css they need. Initially I will end up with many more but smaller .js and .css files, but I can combine them at run-time later. I just want to encapsulate these controls so the pages that use them know less about what it takes to use them.But I am running into a problem. I am using OnInit or OnLoad to register the .css and .js as needed. Unfortunately, none of these methods is called if the control is not visible the first time you hit the page when all the .css and .js needs to make its way to the client. It isn't until later on that the controls are enabled for thier specific functions that they are visible and could emit the .js or .css. Then it's too late!
Do I have to bite the bullet and hand-include the right .css/.js on the pages I use these controls on, or is there a better way to 'inventory' the controls in use to get them to emit what they need?
I have an aspx page which contains a web user control as below.
[code]...
In the Page_Load method of the above page I am setting the Visible = true/false (based on some condition) for the WebUserControl1. WebUserControl1 contains lots of control itself. But I don't want to initialize the controls inside WebUserControl1. Is there anyway we can avoid initializing the ChildControls of WebUserControl1?
So imagine a piece of Javascript as the first script on a page along the lines of
var MySuperObject = new (function () {
this.SuperObjectInit();
})();
Now imagine that everything that proceeds this script (or a large portion therein) requires the SuperObject to have met its load conditions and loaded correctly.
Assuming for whatever reason the loading of the object fails I need to abort loading the rest of the page and the scripts in particular.
I know the majority of you are going to scream why not have your function issue a callback onSuccess and onFailed but the problem is this is in a ASP.Net project with masterpages, nestedmasterpages, usercontrols and so forth (each of which have their own dependencies and scripts); rendering such an approach problematic.
The other option (I assume) is to use window.location = "myErrorPage.html"; but I dont like the idea of having to create another page for an error message or the fact that it causes a redirect.
What I am hoping to do is something along the lines of
StopLoadingPage();
document.write("Error has occurred");
1) As per my understanding, Session variables like HashTable and another variable in Session must be initialized. The best place as per my knowledge is Sesson_Start Event. But at some post its written that we must do that in Application_Start. I think it is not true, as that could lead to problems with different user sessions. Reference is this [URL] Let me know about the concept.
2) Storing variables like string, boolean and etc in Session is slower than storing objects in Session like HashTable, Arrays etc.. becuase they dont require boxing and unboxing. Is that true? Reference. [URL]
I am getting the following error
'Event handlers can only be bound to HttpApplication events during IHttpModule initialization.' at the following code (line in bold or double **)
protected void Application_BeginRequest(object sender, EventArgs e)
{
HttpApplication app = (HttpApplication)sender;
**app.EndRequest += new EventHandler(Application_EndRequest);**
}
protected void Application_EndRequest(object sender, EventArgs e)
{
UnitOfWork.Commit();
}
which is mentioned in Global.asax file.
Debugging using the ASP.NET Development server is extremely slow to initialize. The behavior I'm getting is that if I launch the DevServer from VS2008, the first attempt to load a page takes minutes. After that, it's fine. Before the first page load, the DevServer UI responds to input normally (I can bring it up from the status area, use its context menu, and move the window around) until the first page load comes in. Then it shows the busy cursor (spinning blue ring) for 2-6 minutes before finally completing. There is no significant processor or I/O activity during this. After that, it runs normal speed, quite fast.

<%@ Page Language="javascript"%>'m writing a website that's a little heavy on the database connection calls, so I've decided to try to encapsulate it in a Javascript pseudo-class. When I try to instantiate the MySqlDataAdapter, I get the error "Format of the initialization string does not conform to specification starting at index 0." While I can appreciate this, I've used the same connection string (more or less) across many pages now, without issue when I'm not trying to use this class.I'm a little confused - does anyone have any idea why line would be throwing this error?

I've the Javascript code to do a confirmation before deletion of some records
function confirmDelete()
{
if(confirm('Delete all?'))
{
return true;
}
else
{
return false;
}
}
I've the button code here
<asp:Button ID="btnDelete" runat="server" onClientClick="return confirmDelete();" onClick="btnDelete_click" />
If i've the button outside an update panel (basically i'm using RadAjaxPanel by Telerik) it is working fine. But when the button is inside an ajax panel, even if i click OK for deleting the records the server side code is not called.
