I've gotten an error that I don't understand and I was hoping someone could shed some light on what's going on.First off, here's the VB function that causes the error:
<WebMethod()> _
Public Function GetPortAppraisals() As DataSet
Dim cn As SqlConnection = New SqlConnection("server=***; ASP.NET Version:2.0.50727.3082

I'm using Visual Studio Development Server (Visual Basic 2010) and it works fine. Now I've enabled NTLM Authorization because I want to test the website using a different user account. Now when I try to access the website I always get the following error page:
Server Error in '/' Application.
HTTP Error 403 - Forbidden.
Version Information: ASP.NET Development Server 10.0.0.0 .I'm using a test account which is a normal user within our domain. I've already set the access rights in my project folder to Full Access for this user but it does not help.
When I deployed my project on a server, in certain circumstances, I get an error page that indicates I should create a custom error page. I was wondering how exactly I would implement this custom error page the server asks for to give me a precise and helpful message or preferably, how I would get the error to just display on the main page?This is the error message I got below
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
[code]....
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

View 1 RepliesI have created a project in VS 2008. Now i want to install it on web server. I have copied the whole proj along with .sln file in inetpub/wwwroot folder and also created virtual directory by going in IIS and clicking in Create button. The project is working well in VS but

View 2 RepliesI am having an error coming up talking about my syntax. Now I know how to do something close to this in straight SQL but having a little bit of a problem in VB.Net Applcation.'This gets the Unique Identifier for the Name selected by the user for the county table
SQL.Connection = con
SQL.CommandText = "Select CNTY_UID FROM COUNTY WHERE CNTY_NAME = '" & Me.cboCounty.Text & " AND ST_UID = '" & ST_UID & "'"
Dim CNTY_ID As Object = SQL.ExecuteScalar
CNTY_UID = CNTY_ID
What is happening here is the user is selecting the state from a list in a combobox link to a database. Depending on the choice the county combo will be filled with just the counties for that state. The county table in the database has all the counties in the U.S. which some of them have the same name. So to get the unique id for the county I need the county name and the state unique ID. This is inside a TRY statement and the error talks about a syntax error at 37.

I've developed a small HR program that connects to the SQL database which is on the local PC. I've created an ODBC connection to connect to this server and the program works fine. I've used VB 2008 Express edition to develop.
My concern is now I want to install this EXE on a server. ON the server, I've created the same databses and successfully created an ODBC connection on the server as well. Also created one shared folder. I copied all my EXEs and DLLS on to this folder. On the server I was able to execute the program without any problem.
From a remote client, I opened this shared folder and try to execute and it was giving me an ODBC related error, basically it was not able to detect the SQL connection.What I want to achieve is to have one EXE. The program did not throw any other errors.
I have a Client/Server application. Both Client & Server use to be in 32-bit machines. Every thing was working fine.
When I moved the "Application Server" to a 64-bit machine, I am getting "Error converting varchar to datetime" in almost every screen that has a date picker in it.[code]...

I'm using VS2010, vb.net, .net framework 4.0, and SQL Server 2008 Express on Windows 7 Pro with all updates installed. I have developed a website that uses memberships, profiles, and roles. I allowed the built in providers to create the aspnetdb.mdf file for me in the App_Data folder. I added a number of my own tables to aspnetdb.mdf so I would have a single database for all my site's data.
I am hosting the site on my own server. It uses Windows 2003 Server, IIS 6, SQL 2008 Express, and all of my software including the OS is up to date with the the latest servicepacks, updates, and all of the .net framework updates including 4.0. There are no updates left to install and I'm sure that my issue isn't due to a missing update or framework version.
I copied the aspnetdb.mdf and .ldf files from my app_code folder to the sql server express folder on my server and attached the database. I do this because I don't want the file to autoattach, because I will likely use a commercial hosting service in the future. I added a sql server user with ownership rights to the DB. strong text
I then modified my connection string in web.config to point to the UNC of my SQL Instance on my server and to authenticate with the sql server username and password that I set up with ownership rights to that database. I updated my membership, role, and profile providers in my web.config file to use the new sql connectionstring and I was sure to include the application="/" setting and to use before each provider.
I can run the site just fine from my development machine. I can log on to it and use all of its features. However, when I publish the site to my server I can access the site, both locally over my intranet and over the internet. I can navigate around on it and it retrieves all of the data from the tables that I added to the database myself, but when I try to log on to it or to create a new account (basically anything that uses memberships, roles, or profiles) the site crashes with the error and all of the data below.
I've checked to verify that the application name in my aspnetdb database is in fact simply "/". I've ensured that I'm running from an application pool that is using the 4.0 framework. Much of the googling and reading that I've done seems to indicate a problem with my providers, but I can't understand why it works perfectly on Casini (or whatever the development server is called) on my local machine but crashes on my web server. In both cases they are connecting to the same database.
I would be so grateful if anyone could tell me what I'm doing wrong here. Following are the full error displayed by my server when the site crashes and also what I feel are the relevant sections of my web.config file.Full content of error message and relevant sections of web.config are below:

I have a very simple .net application for testing SMTP on .net. But i am receiving this weird error.

I have a console application created in VS2005, with a web reference created via WSDL.When I run on my local machine (and I have a browser up) I can access the web service fine (if a browser is not up I get the 407 error).I understand this,since my local client machine MUST go through the company proxy (I assume the proxy is resolved when I sign start the browser).When I copy the application to our server, the 407 proxy authentication required error ALWAYS comes up.The thing is, on the server all check boxes in internet options/connections/lan settings are NOT checked. i.e. the server DOES NOT go through a proxy.I installed wireshark to help track down the problem and it shows that when i access the web service wpad is being called and our proxy server is being called.is there a .net configuration that allows me to say "ignore the proxy".I have already tried variations on the system.net section of the app.config file: [code]It seems that no matter what we do (including changing registry settings) this application ALWAYS tries to go through a proxy.
