I've created a new class in App_Code
namespace Site {
public class MyClass {
public MyClass() {
}
}
}
this is my Global.asax.cs
[code]....
The error is in: MyClass myClass = new MyClass();
The type or namespace name 'MyClass' could not be found (are you missing a using directive or an assembly reference?)

View 5 RepliesI 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 a PlannerShiftView user control in the root folder of my ASP.NET web site. In my App_Code folder, I have a ShiftViewTemplate class that needs to instantiate a PlannerShiftView (for a TemplateField in a GridView). The problem is, the following code doesn't compile because the PlannerShiftView type is not available in what I deem to be the App_Code 'phantom namespace'.
Please can somebody explain to be what is happening here, as well as what to do. I know I can just move the ShiftViewTemplate out of App_Code, going against convention and without explantion, but that is something of a hollow victory.
I am relatively new to asp.net environment.Recently working on a project, i discovered a problemi.e. I had to add using system.io to all file functions in any page. same for using sql functionsi.e. any method for that namespace had to be used in full like By adding the following section in web.config , ALL my pages automatically have access to that namespace
<namespaces>
<add namespace="System.Data"/>
<add namespace="System.Data.SqlClient"/>
<add namespace= "MySql.Data.MySqlClient"/>
<add namespace="System.IO"/>
</namespaces>

am currently working on a web application, whereby I want to add code to the Application_BeginRequest method of the Global.asax file, without adding code to the Global.asax file, which sounds a little crazy, let me explain a bit more.If anyone has ever developed in sitecore before, they would have seen that the Global.asax file has empty methods, however it has 'using Sitecore;' and the global.asax file provided does not inherit from System.Web.HttpApplication.
View 1 RepliesI have an ASP.NET application where i am tracking my applicaion level erros using golabl.asax On_Error method.I will send an email to my id when there is some error happened in the site(ie :" when the application _error being invoked) Now From my global.asax's Application_OnError event, how can i get the URL of the page where this error was raised ?
View 3 RepliesI want to make sure of one thing. I have implemented the Application_Error() method of Global.asax. In my application some where I have a try catch. If an exception is trown and that exception is handled by a catch block. Does this envoke the Application_Error() method in the global.asax
View 4 RepliesI have set up custom error on my server and i'm redirecting to a page as shown below
<customErrors mode="On">

When it gets to the page servererror/default.aspx I need it to send an e-mail to me with the exception.message
Here's what i'm trying but it won't work

i have the following code in my global.ascx and when i click a generate error button the code gets run but seems to fail on the insert error into the DB.
I want the error to be saved to the DB and redirect to default.aspx.
pretty standard stuff.
the error i get is: exe.Message = "Incorrect syntax near 'System'." (looks like somethign with the SQL objects used in global.asx)
void Application_Error(object sender, EventArgs e)
{
// Code that runs when an unhandled error occurs
Exception ex = Server.GetLastError();
StringBuilder theBody = new StringBuilder();
theBody.Append("Error Message: " + ex.ToString() + "

I'm working on a small web application, and I wanted the user to be redirected to a simple error page anytime an exception was encountered. So I wanted to redirect the user to generic Error page "Oooops.aspx" that will log the error in page_load.
I'm thinking that I can use Application_Error in Global.asax, where I can redirect to "Oooops.aspx" so that it displays a friendly error page and it logs the exception (through Server.GetLastError()). I can also use web.config and add "<customErrors mode="On" defaultRedirect="Oooops.aspx"/>" It'll redirect me to a friendly error page and it will also log the exception. What's the difference between these two? Should I use both of them, or just one? And which should I use?
In the global.asax file, I capture the error details (if one occurs) and I have it send that error detail to an email address.
I am finding that it's reporting all sorts of strange ones when the website gets hit with a crawler....or at least I think it is. ( HTTP_USER_AGENT: Mozilla/4.0 (compatible; Synapse)).

Error Message: Input string was not in a correct format.
Error Message: Invalid character in a Base-64 string.

I'm very, very new to the asp.net world and I was running through the create the movie db tutorial that is located in the learn asp.net mvc section of this website. Everything is fine until I create my home controller and edit it like on the site. Here is the first part of the code I have that has the error in it:
privateMoviesDBEntities _db = new MoviesDBEntities();
This is all on one line in visual studio but i get an error saying that the type or namespace 'MoviesDBEntities' could not be found (are you missing a using directive or an assembly reference?). I have checked the spelling and I have the using MovieApp.Models; up above so if anyone has any insight that would be great.
I have also tried performing the manager contact sheet tutorial and get the same error in this section of the code.

I started an app in VS2008. I did it as a web site. I installed VS 2010 (yay) today. I wanted to start over as a web project. I made a Master Page. I made content pages. One of my content pages has a form on it. Super simple text boxes and submit.
I added a folder called App_Code and placed my class files there by doing Add New Item and pasting the code into the new class. I have person and persons. The persons collection class references person. In the same folder, the persons class finds the person class. Up one level in a page's code behind, I am gettingthe error
The type or namespace name 'person' could not be found (are you missing a using directive or an assembly reference?)
For giggle, I move person.cs up a folder. Still cannot find the person. Persons collection class still CAN find person. My code behind cannot find it.
A little reading tells me I have to set that folder as an app folder in IIS. I am running Windows 7 ersonal... I cannot find IIS. If not there, I ask myself what they heck is my app running under?
for being such a noob. Anyone know what is going on here?

When I run my app locally I get no errors. No error from Global.asax, no redirection to an error page. Everythings works fine.
When I deploy my app to a test server, my app run there with no errors. No error from Global.asax, no redirection to an error page. Everythings works fine on the test server.
But when I deploy my app to production server, the app runs fine but I keep getting errors (emailed to me) from Global.asax. On production server we have these security apps that run and keep hitting all URLs of the app on the server. Just to make sure they are working fine. When these security app hit URL of my app, my application runs fine but it gives out this global.asax error. The funny thing is that error is empty. The error are emailed to me and the email is empty. Nothing there.
There are several other apps running on the same server. My app has its own app pool and is configured correctly.
I just upload my website to godaddy server and i am having an error.

I am fairly new to ASP.net and web page development. I normally create Windows Apps, but the move is on to web pages. I have read and tried a number of posts on this matter, but none of them resolved the problem I am having. I have created a web site (I'm positive it is a web site) and added a class. Visual Studio automatically created and added the class to the App_Code folder. Accordingly, I added the get/set methods to the class and made them public. When ever I try to access the class from a code behind for any page, I get the class name, but nothing more. Intellisense shows only Equals and EqualsReference - no variables. I'm used to using classes in windows forms application and this would make life so much easier if it worked like it is supposed to work.
View 2 RepliesI have created a simple ASP.NET Website in Visual Studio 2008. I have a static C# class (lets call it someClass) contained in a separate file in the App_Code folder. I call a method from that class in my page's code behind like so:
someVar = someClass.someMethod(someParam);
This compiles correctly in VS 2008 but when I move it over to my IIS server, I get the following error (CS0103): Description: An error occurred during the compilation of a resource required to service this request.
