IIS Issues - Unable to start debugging on the web server. The underlying connection was closed. The connection was closed unexpectedly.

Auto-Start Web Applications with ASP.NET 4
Some web applications need to load large amounts of data, or perform expensive initialization processing, before they are ready to process requests. Developers using ASP.NET today often do this work using the "Application_Start" event handler within the Global.asax file of an application (which fires the first time a request executes). They then either devise custom scripts to send fake requests to the application to periodically "wake it up" and execute this code before a customer hits it, or simply cause the unfortunate first customer that accesses the application to wait while this logic finishes before processing the request (which can lead to a long delay for them).

ASP.NET 4 ships with a new feature called "auto-start" that better addresses this scenario, and is available when ASP.NET 4 runs on IIS 7.5 (which ships with Windows 7 and Windows Server 2008 R2). The auto-start feature provides a controlled approach for starting up an application worker process, initializing an ASP.NET application, and then accepting HTTP requests.

I think in many time developer need this event, which is not provided by any browser and it is not captured by any javascript event.In this Article you see how you capture this event and how you force the browser to load the page from server.

An approach to displaying a "please wait" message/animated gif following a button click using encapsulated client-side JavaScript.

It is often useful upon a form submission in a web application to display a "please wait" message, or animated .gif image, particularly if the submission process lasts a few seconds or more. I recently developed a survey submission application in which internal users upload excel spreadsheets through a web page. The application inserts the uploaded data from the spreadsheets into a database. The upload/insert process may only take a few seconds, but even a few seconds on the web is a noticeable wait. When testing, some users clicked the upload button repeatedly; it was useful to provide a visual clue that the upload was underway. For that matter, it was useful to hide the upload button altogether, preventing multiple clicks. The control presented here, a subclass of the Button control, demonstrates how client-side JavaScript code encapsulated in an ASP.NET server control can provide such functionality conveniently.

All of the sudden I'm getting the following error on my local web server (Win7 64bit, IIS 7.5).  I've uninstalled & reinstalled IIS locally and it didn't fix it.  IIS is set to start up automatically and I can see that the service has been successfully started.  Upon a fresh reboot if I go into IIS and click on start website I get the following error:

"The process cannot access the file because it is being used by another process.  (Exception from HRESULT:  0x80070020"

If I try to start debugging on my local website project I get the following error:

"Unable to start debugging on the web server.  The underlying connection was closed.  The connection was closed unexpectedly."

Any ideas on what I can try?  I've been doing research on the issue and Microsoft suggest making sure no other service is listening on the same ports.  I've verified that this isn't the issue.

Hi.

We had a website deployed on IIS server remotely say www.liveserver.com.

We recently decided to make a copy of the website internal to the organisation so we brought a server and copied all the code from live server and configured it and say it is http//archives-testserver.com

Everything seems to work fine but while navigating and clicking on certain module  links within  http//archives-testserver.com......the domain name is getting rewritten to www.liveserver.com and user is made to navigate on the live site. I wonder where this configuration is with in IIS...

I looked under properties under website identification and everything is referring it as http://arhives-testserver.com.  also thr is a file called securityRedirect.inc and ifor handling errors and all the references have been changed and couldn't find anything in web.config.

I would really appreciate if anyone can guide in right direction, where else to look for probable reference to live site?

Dear All,

I cannot add a new column in existing table.

I have a two tables ['ev_event_how' & 'ev_events_event_how'] has relationship between these table.

Ex:
Table: 'ev_event_how'

UID - Event[PK]

 

Ex:
Table: 'ev_events_event_how'

UID - Event[FK] - Desc

I want to add a one more column[IsDelete] in both table. But Sql server is not allowing to add the new column, Showing various errors like

1.cannot add a new column-Unable to modify table.Invalid object name 'MSED_Logs.DatabaseLog'

2.TITLE: Microsoft SQL Server Management Studio
------------------------------

User canceled out of save dialog
 (MS Visual Database Tools)

 

How can I make it add a new column in existing table?

 

 

 

 

 

 

 

I'm trying to figure out how I can get around an error I get when multiple users are accessing different my site. I'm getting an error:

there is already an open datareader associated with this connection which must be closed first

It's not the same query everytime but I recently triggered it on this statement:

Dim adapterSavedState As New SQLDataAdapter("SELECT SavedStateContactView, SavedStatePropertyView, SavedStateTransView, SavedStateCompanyView FROM WebusersProfiles WHERE ContactID = '" & Session("ContactID") & "'", myConnection)
    Dim dtSavedState As New DataTable()
    adapterSavedState.Fill(dtSavedState)
         Dim rowSavedState As DataRow
         For Each rowSavedState In dtSavedState.Rows
             If Request.QueryString("View") = "Contact" Then
                SavedState = rowSavedState("SavedStateContactView").ToString()
            Else If Request.QueryString("View") = "Property" Then
                SavedState = rowSavedState("SavedStatePropertyView").ToString()
            Else If Request.QueryString("View") = "Trans" Then
                SavedState = rowSavedState("SavedStateTransView").ToString()
            Else If Request.QueryString("View") = "Company" Then
                SavedState = rowSavedState("SavedStateCompanyView").ToString()
            End If
         Next rowSavedState

I define my connection in my basepage

    Public Dim MyConnection As SqlConnection
    Public Shared Dim strSite As String = "dev"
        
    Protected Overrides Sub OnLoad(ByVal e As System.EventArgs)
        myConnection = New SqlConnection("server=xxxx;database=xxxxx;User ID=xxxxx;Password=xxxxx;")

Where is my issue and how can I overcome it? This is a .net 1.1 site so MARS I know is not available...

Hi

I need to know if a web application deployed in a 64-bit server runs as a WOW64 process or a 64-bit process if the web application's pages are compiled as PE 32/x86 ?

I mean I have read a lot about normal console applications or executables with PE 32/x86 run as WOW64 on 64-bit servers. But what about web applications( all i can compile is the pages which are dlls)? The only process I can think of is w3wp.exe for web apps. Please explain. I am confused.

Thanks in advance

Hello everyone,

  I have encountered a problem on the pageload which is if I click a button within the page it generates a new random number.  Once the page has loaded for the first time I want the variable to remain the same. However after I clicked the button it generates a new random number again.

Does anyone know how to solve this problem? Deeply appreciated.

Hi All,

i have a program in vb.net..i use the webrequest to post the data to another page (http://localpost/posReceived.aspx), and use the webResponse to get the back the response from the remote page.

When i run this program, it returned error "The remote server returned an error: (403) Forbidden.". I have no idea on this. Coz my aspx page and posReceived.aspx are placed in the same server and same directory. I supposed it should be worked without any security concerns.

Can anyone help me to solve it. Thanks a lot!
