Public Function ScreenScrapeHtml(ByVal url As String) As String
Dim objRequest As WebRequest = System.Net.HttpWebRequest.Create(url)
Dim sr As New StreamReader(objRequest.GetResponse().GetResponseStream())[code]....
But what if the URL is[url].... or something else that doesn't exist, how do I handle the error? The program is crashing right now.

View 3 RepliesI don't know what this is called so I've struggled to find an answer from google but I have a vague memory of it from t'old days.I've sub-classed (* see below) about 8 framework controls, overriden some properties and added some functionality into each one.The changes I have made are identical in every case. If I make a change, I have to go through each class and apply the same change there.I was hoping there may be a keyword such as <IncludeSourcefile "common.vb> that I can put into each class.
(* note) I use the term sub-classed but I don't know if that's the correct terminology. I've also seen it used for call-backs. Is sub-classed the correct term to use?

I refreshed my data sources to include additional items from the SQL Server databases and it appears that my entire data source from my VB.NET project disappeared.I am using Entity Framework. I may have clicked on something wrong, not quite sure. Unfortunately I can't recreate the Data Source without creating a new Entity and Data Model.I can delete the entry in the App.Config file and recreated it, however things aren't quite right.Is there a way that I can recreate my Data Source from the entry that is in my App.Config file...since that appears to have remained intact.BTW, I can go to my Data Model and successfully refresh from there, however my project isn't connecting to the database so I have quite a number of errors until I can get reconnected.

Server Error in '/' Application.

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.
