I've been given the thrilling task of re-writing our exception handling system. Whilst I will state that handling exceptions from an application-wide point of view isn't something we want, typically it's unavoidable when our team are understaffed for the sheer amount of work we need to push out the door, so please, no flaming the globalised solution to exception handling here
View 3 RepliesI need to add the code below to my global.asax file. It begins with a Sub Application_BeginRequest . My global.asax already has a section that begins with Protected Sub Application_BeginRequest(ByVal sender As Object, ByVal e As System.EventArgs) I'm assuming that I should not have two sections with Sub Application_BeginRequest I tried putting the core of the new code into my existing Sub Application_BeginRequest and it returns no errors but it when I try to view the website in VWDE 2010 it times out. Something is causing it to run or load slowly.
This is the code that I'm adding:

i have a project with 1 main form, in form load i call 4 subs which call data from an api. I have added a splashscreen from the add form menu.

I need a function in global.asax file which gets called only once when user enter a page url. application_beginrequest gets called 50-60 times in a single page( as to render a page several requests go to server.)
i though of a solution - I can write my fucntion in global.asax and call it on page load of other pages but in that solution I need to call it in every page. I would prefer something which is to be done only in global.asax

I'm trying to use the Global.asax file in the root application of the website to catch requests for pdf files in the root that don't exist any more. I've configured iis to send pdf requests to asp.net. The whole thing works perfectly on development. It also works on the live system with missing .aspx pages, but not .pdf. Instead an "Error Code 64: Host not available". I'm using the Global.asax file to avoid the web.config and child applications (1.1 & 2.0) inheriting settings.[code]...
View 1 RepliesI have a huge website (containing around 5000+) pages. There is a theme functionality in the website where user can choose different colors for their profile. Now i want to use the ASP.net theme feature and put different CSS (for different colors) in the theme folder and in Global.asax i want check the user theme and render appropriate link element with the css.

I was wondering if there was a way to catch all unhandled exceptions in a visual studio project. My project does not have any files named global or global.asax so I was wondering if there was some other way to catch any and all unhandled exceptions? So far I've tried to put exception handling around specific blocks of code, but it doesn't have any effect.
View 3 RepliesSo I handle all exceptions in my project within my Global.asax page. For example, on a random page I could have:[code]So my question is in the Application_Error method, do I need the try/catch block when trying to write to the database? I'm thinking I would in case something goes wrong with the connection, etc. - but is this really necessary? Also, what would I do in the catch block if there is an error? At that point I would be catching the error of logging an error which is confusing in its own right.
View 1 RepliesNormally I just redirect to a custom error page in on the Application_Error event, but I have a specific error for which I'd like to display an alert message while the user is still on the page which triggers the error. How can I make this happen?

I am handling errors via my global.asax in this method:

Dim sw As System.IO.StreamWriter = New System.IO.StreamWriter(LogFilePath)

In my code I currently have no other error handling. Should I still insert try, catch, finally blocks?

In Global.asax, is there a way to handle SQL Timeouts elegantly, and display a message on the requesting page explaining the error? I know Global.asax has the Application_Error and Error events, but I'm not sure which (if any) I could use to accomplish this.
Related, can I access the page instance which raised the error that Global.asax is handling?

I have a variable whose scope needs to be global, because it needs to be called in a function as well as in a button press. So I declared the variable in a Module so it would be global.The problem is that the value of this variable needs to be equal to the value of the text property of a textbox in the form.You enter a string into the textbox, in this case I entered "Hello". Then you click the button and it displays what you wrote.You click OK in that message box and change the value in the textbox. In this case I changed it to "Goodbye". Then I hit the button again, but the variable did not change values and the messagebox displays "Hello" again.

Here is the entire source code:
Module Module1
Public strDataValue = frmTest.txtDataValue.Text
End Module

Note: This is just a demonstration of a problem I'm having in a much larger program so the variable does have to be global.
If we declare a global variable in module in vb.net, we can use that variable in anywhere in project.
How can we achieve same thing in C#.
Previously when we tried to convert a vb.net project to C#, we succeeded in removing the syntax error but we can't access global variable in a form.

View 1 RepliesI'm trying to build a language dictionary in VB NET in order to be able to have several languages in the application.This dictionary has a init method that loads from database the entire dictionary and stores it in memory.In the rest of the classes of the project, I added the reference and I can use directly the object without create a new instance because their methods are shared.
how i have to load the dictionary content in order that the rest of classes only accessing to Language.GetWord method obtains the properly record of the collection, same way as My.Settings class.When My.Settings is used from any class the values are loaded. I'm looking for the same effect.This is the code of the class:
Public Class LanguageProvider
Private Shared CurrentLanguage As Collection
Public Shared ReadOnly Property GetWord(ByVal Label As String)
[code]....
Function LoadLanguage must be called when the application loads, in order to access once to database. After that property GetWord must access to the collection with the words and return the result. The problem is that the instances are not the same and the dictionary is not loaded when a class uses it.
Im creating a desktop app with multiple forms. My ideal aim is to create 1 MenuStrip to use throughout the different forms (the same MenuStrip) appears on the different forms. otherwise I'll be copying the MenuStrips from 1 form to another and copying the Event code. What is the best way of doing this? I've created UserControl, put my MenuStrip on it along with me Code, then I load an instance of it whenever a new form loads. This seems to work fine until I want close the Main Form. I've tried ' Me.Hide ' but that just hides the UserControl. So the MenuStrip appears on Form A, when i click a Menu Item I want it to close Form A and open Form B.
