Web Forms :: Getting Error Trying To Run An App In VS 2008?
Oct 19, 2010
I've upgraded a VS 2005 app to VS 2008, and tried to run it. I get some very strange behavior. Something, I don't know what, comes up and says:
"Unable to start debugging on the web server. <!DOCTYPE html PUBLIC "-//W3C/DTD XHTML 1.0
Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>IIS 7.5 Detail Error - 500.19 - Internal Server Error</title>
and then it goes on with a lot of HTML. But the weird thing is that this window isn't one I could scroll through, or copy anything out of.
I have an existing project with a silverlight3 app. First I created SALESservice.svc.This is working fine. Now I added another TARGETservice.svc to my project and rebuilded my entire project but when I am trying to add the service reference in to the silverlight app I get the following error:
There was an error downloading metadata from the address.verify that you have entered a valid address. I didn't write any code in ISALESservice.svc AND ITARGETservice.svc . I have written in SALESservice.svc.cs AND TARGETservice.svc.cs files.Is this causing error? But for SALESservice.svc it is working. I didn't add any code in web.config file.
I have this strange error coming up in VS2008, where is says a variable in not declared in HTML view, when it clearly is declared in the codebehind:Can anyone help with why this might be happening? I've tried all sorts of things, even recreating the page from scratch, but this keeps coming up.
We have a process that calles a url to pull an image (in this case a .tif image) and it calls this function which works most of the time but recently is getting errors. If I step through the While loop of a 92k file it gets to the end and then errors on the following line:
nBytesRead = stStream.Read(baBytes, 0, MAX_BUF)
I have added a Try/End Try statement which appears to work but is there a better option? The error I get is:
System.IO.IOException: Unable to read data from the transport connection: The connection was closed.
Code: Private Function ReadAsByteArray(ByVal stStream As Stream) As Byte() Dim msBuffer As New MemoryStream() Dim swWriter As New StreamWriter(msBuffer) Dim nTotalBytesRead As Integer Dim nBytesRead As Integer Dim baBytes(MAX_BUF) As Byte nTotalBytesRead = 0 nBytesRead = MAX_BUF While True 'ORIGINALLY THE TRY IS NOT THERE Try nBytesRead = stStream.Read(baBytes, 0, MAX_BUF)......
i'm getting error while installing sql server on xp sp2. i have already installed visual studio sp1. while installing sql server it install hotfix for xp KB942288-v3 and KB954550-v5 after show following error message. SQL Server Setup has encountered the following error: Object of type 'Microsoft.SQL.Chainer.Package.PropertiesTypeProperty' cannot be converted to type 'Microsoft.SQL.Chainer.Package.PropertiesTypeProperty'..
While trying to download Visual web developer from HERE I get an error message about downloading visual C++ 2008 sp1 first. I go ahead and download it from HERE, but still no luck launching the program.Here is a pic of the error message.
I have a Default web page that has several text fields on it to allow users to search the SQL 2008 database. The bottom half of the default web page then loads a grid view based on the search criteria and records found in the database. The Select link is visible, which, when clicked brings the user to the next aspx screen that contains the detail view of the selected record, with the appropriate data being displayed from the database.
All continues to work fine when I click the Edit button as I am then brought into the 'Edit' view, if you will, of the details view. The issue arises when I click the Update button when trying to update the record. The same error messages are received when I try to insert a record too.
Here is the code that creates the details view and the necessary update/insert record coding. The error received is: Index (zero based) must be greater than or equal to zero and less than the size of the argument list. The error is placed on line 76 which is:
Code: Dim txtSerialNumber As TextBox = CType(myDetailsView.FindControl("txtEditSerialNumber"), TextBox)
I am having some issues accessing a literal in a usercontrol.
I get the following error: System.NullReferenceException: Object reference not set to an instance of an object. at page.sbPageLoad(String sTypeCD, Int32 iCategoryID, String SortExpression)
I typically don't use the sqldatasource control but trying it out and can't seem to get the delete function working. It doesn't seem to be passing a parameter to my stored procedure. The error I get is: Procedure or function 'sp_DeleteCraigsListEntry' expects parameter '@craigslist_search_id', which was not supplied. Any thoughts?
i was normally using VS2005 and SQL server 2005... i upgraded to SQL Server 2008... and then... i could not build my project anymore... because of this error: Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
I'm having difficulties with a clean SQL Server 2008 + SP1 (64 bit) install. I'm using Windows 7 Ultimate 64 bit with VS2010. The Microsoft SQL Server 2008 Service Pack 1 (KB968369) is installed via Windows Update. I installed SQL Server Management Studio (64 bit) via the Microsoft website. When I open SSMS and try to login with Windows Authentication to (local)/localhost/[computername] I get the following error:
[Code]....
I don't understand this because I opened the inbound/outbound ports for 1433/1434. As wel as inbound/outbound exceptions for the programs
I just got a new windows server 2008 dedicated server and I can't for the life of me get it to serve up web pages. It has every .NET framework installed on it has the web server role added with the ASP.NET feature checked. I made sure that ASP.NET 2 and 4 are allowed in the ISAPI extensions.
Not just aspx pages but even if I create a .html page, it still gives the 404 Not Found error. Also, I should note that it's the basic browser 404 page, it's not making it to the ASP.NET isapi handler. It gives the same 404 both remotely and locally so it's not a firewall or router issue.
The code below is generic, found in a variety of places, including a book I have. I have used it as a base for a working program in VS 2005. Now I've resurrected it with my current Visual Web Developer 2008 Express Edition and I seem to have problems connecting it to my default development server (I don't have IIS on my XP). The error is: (500) Internal Server Error.

I am getting an object required error and I understand it's because the object I am looking for doesn't exist yet, but I don't know why it doesn't exist yet. Here is my code:
Code: <tr><!-- This is the row with Effective Date --> <td nowrap valign="top"> <asp:label id="EffectiveDateTitleLabel" runat="server" Width="120px">Effective Date:</asp:label> <p></p> </td> <td nowrap valign="top">
[Code] ....
What I want to accomplish is when the selected effective date is greater than 01/01/2014, hide the TotalEmployees dropdownlist (and label, but for now I'm just trying to do the DDL).
Here's the js:
Code:
<script type="text/javascript"> function SetTextArea(selectedValue) { alert("selected value changed to " + selectedValue); var selectedDate = new Date(selectedValue);
[Code] ....
I get the alert that it could not find totalemployees. Is this because EffectiveDateDropDown is in an UpdatePanel so the two dropdowns don't exist at the same time? Or something like that?
I don't have to use JS. I thought it would be easier than using AJAX. But it's not if it doesn't work.
I'm trying to make a webpage that get's a url from another web page (this other webpage works fine in a browser, both IE and FF) but when I make the webrequest call the returned page is a 500 internal server error. Here's the code:
Imports System.Net Imports System.IO Partial Public Class _Default Inherits System.Web.UI.Page Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
[Code] ....
Here's the error I'm getting:
Code:
System.Net.WebException: The remote server returned an error: (500) Internal Server Error. at System.Net.HttpWebRequest.GetResponse() at SW_GetDownloadFile._Default.GetDownloadFile(String Url) in C:Documents and SettingsvmMy DocumentsVisual Studio 2008ProjectsSW_GetDownloadFileSW_GetDownloadFileDefault.aspx.vb:line 24
The DownloadHandler.jsp page simply displays a text line being a text file download link, there's no html formatting or anything and when I paste that text into the browser it shows the text file contents just fine, I need my asp webpage to get that text file link so it can turn around and open it to parse the info.
I'm not in control of the DownloadHandler.jsp page so i can't alter that, the Java team wont make any changes to it either.
I m very new to ASP.NET and using Visual Web Developer. I m facing problem in Website Authentication tool where i want to create a login but it gives the error on Password showing the message highlighted in red in attached file.
I've been working on this error all day! I have a dataview created from a sqldatasource control and I'm trying to assign it to a gridview but I get Object reference not set to an instance of an object. Code: Try Session("dsCustomer") = "Y" [code]......
Can't I assign a dataview as a datasource? Or not?
I had to reload vwd 2008 express and sql 2008 express on my laptop. After loading cannot launch vwd, get this error message. Can anyone please suggest a remedy "Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed."
I'm trying to publish an ASP.NET website over an IIS 6.0 (Windows 2003 Server), and I have some troubles trying to connect to the database. Curiously, I have installed another ASP.NET website into the same IIS 6.0 with the same properties and security parameters and can connect without problems with the same database. The application that works fine is almost the same that the one that can't connect with SQL Server (actually is the same but with several modifications).I'll enumarate some information related to the problem:
S.O: Windows 2003 Server SQL Server Engine: SQL Server 2008 SQL Server accept remote connections? Yes. ASP.NET version: 2.0.50727 The connections via TCP/IP are enabled to the SQL Server instance? Yes. The corresponding user that I have in the connection string, actually exists into the database with the "owner" role? Yes. ORM Tool used: nHibernate
I get the following error when I try to run the aplication into the browser:
Error while establishing a connection to the server. When connecting to SQL Server 2005, this failure may occur because the default settings SQL Server does not allow remote connections. (provider: Shared Memory Provider, error: 40 - Could not open a connection to SQL Server)
I made some test. For example, using the web app that works fine I can connect without any problema with the database that uses the web app that can't. With this evidence I concluded that the problem is within the web app and not into the SQL Server instance.
I am trying to put a simple website on my web server. My hosting company only allows .mdb files. When I try to use .mdb files in asp.net visual web developer 2008 I get the following error.
I keep recieving this error when trying to add the toolkit to my application: "There was an error loading types from assembly v:my intranet etProjectinAjaxControlToolkit.dll Request for the permission of type System.Web.AspNetHostingPermission, System, Version=2.0.0.0,culture=neutral,PublicKeyToken=b77a5c561934e089 failed"
This has only recently started happening.. There are already AJAX controls on the page which still work but I want to add new ones with the new toolkit but for some reason cannot add the toolkit anymore. If I copy the toolkit to the local C: drive of my PC and add them I can , but when I then copy my page back to the server, none of the controls are working.
