Nov 9, 2008
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. The splashscreen displays first while the main form loads(calling api data)What i would to do is have a progress bar on the splashscreen with the progress of the mainform load.
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
SplashScreen1.ProgressBar1.Value = 0
updategeneral()

I 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:
<script runat="server">
Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs)
Dim url = String.Empty

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

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]...

I 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. But my problem is, i am not able to access the Page element for adding the link in the page. Here is my code
Dim page As System.Web.UI.Page = TryCast(System.Web.HttpContext.Current.Handler,System.Web.UI.Page)
page.StyleSheetTheme = "Black"
But when i run this code I get a Null reference error.
P.s : My application is very huge so its not possible to have a master page or a base class and inherit it in every page.

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.

So 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.

Normally 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'm open to a modalpopup or any other type of error message, I just want to ensure the user stays on the page where they encounter the error.
This is in reference to this thread: [URL]
Here is the code I'm currently using:
Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)

I am handling errors via my global.asax in this method:
Dim CurrentException As Exception
CurrentException = Server.GetLastError()
Dim LogFilePath As String = Server.MapPath("~/Error/" & DateTime.Now.ToString("dd-MM-yy.HH.mm") & ".txt")
Dim sw As System.IO.StreamWriter = New System.IO.StreamWriter(LogFilePath)
[code]....
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 an asp.net app that launches a modal window upon button_click event. That modal window launches another modal window upon another button_click event.
However, the final modal window's "Page_Load" event is not firing.
The second modal winodw is called via a javascript call from vb.net code behind Page.ClientScript.RegisterStartupScript(Me.GetType(), "Script", "ShowModalWin('brPreview','brPreview')", True)

I have created a windows service and I have two different timer variables in there. 1st one fires off every 5 seconds and then does whats it is required to do. The second one fires every 30 seconds.
I make sure that when the function are getting executed I disable both the timers and enable once the function is complete.My problem is my second longer (30 second ) timer never fires only the first one is firing. I had created this service 3 months ago and it was working fine till now. But now I do not see the timers work properly in a simple windows app i created to test their workings.

I'm not even sure what I need to know. None the less lets say I got a timer with an if event to check if said event is triggered then it fires off some code. The problem is if said event is triggered it keeps firing off the code and I only need to do it one time. Whilst letting the timer keep checking if event happened. I hope I worded that right and here is a rough translation in code. [Code] Is there a way to keep checking if an event happened and only fire off the code one time?

I have an application that contains both test code and production code. The test code points to the test files on the local machine while production is located on the server. I comment out the production code when testing. To save some time I figured I would create a Global Variable integer called pTest and encase the test and production code in a Case statement so that if I set pTest=1 then the test code will run and if pTest=0 then production code will run.

I have code running in the Datatable.ColumnChanging event in my dataset. This dataset underlies a form and conventional drag/drop controls are in place for data entry.when the event triggers and runs, I am running code in the form that checks the dataset.HasChanges property. It is showing False. But this is immediately after the ColumnChanging event has been triggered.Okay, I see by others posts and MSDN that .HasChanges will only be true after moving off the row with the changed column. I have also noted lots of discussion about the advanced binding property of DataSourceUpdate Mode, but that does not address this issue.I guess I can do this by checking the state of the row for the binding source. Just seems odd that the event behind the dataset can be triggered and that does not change the dataset.HasChanges property.

I am wondering if Global.asa can handle a procedure like this:
Protected Sub errore(tipo As Int16)
'Response.Write(Err.Description) 'or your own custom error message
Dim msg As String

The idea is to have a central place to put the routine in instead to copy it into every .vb file that belongs to each .apsx code file.

Here's the item from the View @Html.EditorFor(Function(model) model.BirthDate)
Here's the code from the EditorTemplate (simplified)
@ModelType Date?
<span>
@Html.TextBox("", Model)
</span>
[Code]...
Ok, so after some digging, I found that if I add <UIHint("Date")> to my BuddyClass, then the template works.
So my "new" question would be... why wouldn't it pick this up by default?
