Web Forms :: Global.asax Doesn't Work - Procedure?
Apr 19, 2010
Global.asax
void Application_Error(object sender, EventArgs e)
{
Exception err = Server.GetLastError();
Session["error"] = err.InnerException.Message;
}
web.config
<customErrors mode="On" defaultRedirect="CustomerPage.aspx"></customErrors>
CustomerPage.aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
if (Session["error"] != null)
{
Response.Write(Session["error"].ToString());
}
It does not work. How to call a procedure?

I want to protect one file in a subdirectory with Global.asax. (I know that this isn't the conventional way of going about this) but it works on my computer and not on the server.I have a global.asax file in my root dir and Application_BeginRequest checks if the user is requesting a particular file. If they are logged in, it allows access. If they are not logged in they are redirected to the default page.My problem is this: My code works on my personal computer but does not work on the server. Do I have to configure a setting in the web.config or adjust something on the server? Code:
Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs)
Dim fullOrigionalpath As String = Request.Url.ToString.ToLower
'PROTECTED FILE
If fullOrigionalpath.Contains("/uploads/groups.xls") Then
If HttpContext.Current.User.Identity.IsAuthenticated = False Then Response.Redirect("~/login.aspx")
End If
End Sub

I've put together some code that processes XML files as they're uploaded to the server using the FileSystemWatcher for one of my clients. The XML is uploaded every hour, and the FSW watches a set directory for new files. All is well and works fine in my development environment but I'm using my clients hosting provider (www.webhostforasp.net) and when uploading a new XML file it appears that nothing is happening? It is possible that the hosting provider doesn't allow watchers or calls from the Global.asax?
What would be the best way to find out what's going on there, considering that without running the site in debug mode, I've got no way of knowing what's going on with the Global.asax or the FSW?

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 was given a web app written in VB.net. I am using VS2008. The project has a Global.asax page with Enums declared
Example:Public Enum eCurrentLoc as Integer
Admins
AdminTools
Home
LogIn
Status
End Enum
But in the web application itself I get errors on this line of code:
Ads = Global.eCurrentLoc.Admins
I get the blue scwigly line under Global.eCurrentLoc
The error states 'eCurrentLoc' is not a memeber of '<Defaults>'

I am using a Global.asax in on my webpage to run a function with an interval. In this test I have set the interval to 1 minute to be able to see what happens.
I have declared a timer in the Application Start which should mean that when I open up the webpage after I have uploaded the Global.asax the timer will start.
However with this code below where I try to create a file named newFile.txt, this file is not created. I cant really understand what I could be missing. It seems that the function is not running ?

I have a Global.Asax and Global.Asax.cs file that is specific to my particular Asp.net project. For some unknown reason the code in my Global.asax.cs file is not being executed. I thought that the breakpoints were being ignored, however that is not the case. Because if I try to deliberately force an error to occur, the code is never executed. Below is an example of what I am talking about. The real code in my Application_Start method is not shown below. ANd other methods are not shown as well.
I have tried renaming the Global.asax file and then re-creating it, and that did not work either. Strange because when I try and create a new Global.asax file, the option to create a code behind file is greyed out.
Why isn't my Global.Asax.cs code being executed?
private void Application_Start(object sender, EventArgs e)
{
int x = 1;
int y = 1;
int z=1/(x-y)
}

<authentication mode="Forms">
<forms name=".ASPXAUTH" loginUrl="~/Login.aspx"
defaultUrl="~/Default.aspx" protection="All" timeout="45"
requireSSL="false">
</forms>
</authentication>
Global.asax.cs file has:
void Session_End(object sender, EventArgs e)
{
Response.Redirect("~/Timeout.aspx");

Just for kicks, how do you say, wire up an ASP button to purposely throw an Application_Error exception in the global.asax file?
lets say you wanted to test the functionality of the error handling and what is doing..and you don't have a real error to do it. what is the easiest way just raise this event?

I am redirecting user from http to https if page is not secure from global.asax file in application_Begin event
But there are some pages in which i don't want to redirect to https page. I want to detect any form element which will tell me weather page should be secured or not. but when i check Requet.Form[_Viewstate] it gives me null value. Right now i check like Request.PhysicalPath.ToLower().IndexOf("test.aspx") ==-1 && !page.IsSecureConnection-> redirect to secure page but in future there will be more page which should be on http.
Is there any general way to redirect to https if page i added any hidden field on page "hfIsHttps=1" and detect that element if 1 then go other wise don't go Following is my code global.asax in application_Begin event
[code]....
I want, instead of hard core check for perticular page there should be general way, like each page itself should tell weather it should be for http or https

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'm working on a new C# web application in Visual Studio 2010, and am having problems reading a value in Web.Debug.Config from the GLobal.asax.cs file.
In the Application_Start event I've got the following code:
Application.Add("AppID", ConfigurationManager.AppSettings.Get("AppID"));
I also tried:
Application.Add("AppID", ConfigurationManager.AppSettings["AppID"]);
And in the Web.Debug.Config file I have the following:
<applicationSettings>
<add key="AppID" value="123" />
</applicationSettings>
I also tried:
<appSettings>
<add key="AppID" value="123" />
</appSettings>
And I tried having it in a file path, like so:
<appSettings file="C:MyPathappSettings.config"/>
When running in debugger, I've got a break-point in the Application_Start event in Global.asax.cs. It hits the break point, but in all cases the value coming back from ConfigurationManager is coming back null. What am I doing wrong?

Is it possible in the global.asax file on session_start to check if a url string exists and it it does insert the string into a sql database? The url would be something link http://www.mysite.com?campaign=january.
I would want to capture the january bit and put that in the database for each visitor that uses that url.
