Accessing About 100 Sites At Once Use Classes Or Subs For Each Site?

Mar 1, 2012

I have about 100 websites that I am going to be accessing to scrape some data from (weather, time, etc). When I go to code these babies there will be an abundance of sub routines that I will be creating. They each are going to be accessing pretty much the same type of data.

Should I put them into a Class some how and acces them that way or should I just use Subs and then call them into the Document Completed section of my web browser to run the code? Still sort of confused on the whole Class vs. Sub Routine thing.

Internet Explorer - Programmatically Adding A Site To The Allowed Sites Of The IE Pop-up Blocker

Jun 16, 2010

A few more details. I need to programmatically (Winforms, VB.NET) check if a site is in the Allowed Sites list of the IE Pop-Up Blocker (IE 7 and 8 and Windows XP, Vista and 7) and if not, add it. The application is fully trusted and I don't want to disable the Pop-Up blocker entirely. To clarify some things, this is for a web-automation application with several users across 3 countries. I want to avoid receiving tons of emails and explaining each time how to add the website to the Allowed Sites manually. Also, some of the users have Google Toolbar installed, which also has a Popup Blocker creating trouble to my app. Can this also be done programmatically?

Inheritance In Classes And Extending Subs ?

Feb 26, 2011

I've been wondering if there is anyway to extend a sub of a base class in a derived class or subclass. To date, the only thing I've been able to find is overrides and overloads functions, but to my understanding these functions just ignore your base class's sub and just allows you to run the new one with the same name.

What I want to be able to do is:

CODE:

I'm not sure whether this is possible, or if I'd simply either make a new sub in my derived class that first ran the base's class sub or whether I'd override the base class and then copy and paste the old code.

Accessing A Site That Requires Login

Mar 13, 2012

I am trying to create a small program that checks [URL] for a work order every minutes. While I don't know of any API that I can use, I think it would be easy enough to simply check the page and see if there are any new work orders listed. The question I have is how to access the work order page. Every a few minutes field nation logs you out of their website. At that point I am required to log back in again to access my account. How can I automate or bypass this process so that my program and regularly check for new workorders?

Not Able To View Text Document When Accessing Link From Live Site

Jun 11, 2009

I have created an application which will open a text file on the click of a button, when i am running the application in local, I am able to get the popup asking to open or save the text file, I uploaded the same code to live site there it is not displaying the popup to open or save the text file. It just flashes a window for fraction of seconds and then closes, user is not able to perform any action in that course of time. Text document which I am trying to open is available at both server and local, and path is also correct in both cases.

Below is the code I am using to open the text file:
If (File.Exists(strFolderPath & "" & strFileName)) Then
objFileStream = New FileStream(strFolderPath & "" & strFileName, FileMode.Open, FileAccess.Read)
objStreamReader = New StreamReader(objFileStream)
objStreamReader.BaseStream.Seek(0, SeekOrigin.Begin)

Accessing Instances Of Classes

Jul 25, 2011

I am trying to make a pretty complicated, layered program.I have my main form which creates an instance of another form (addValue and myAddValue). From myAddValue I then want to access a few other classes to do various verification and other bits of code.Here though I have a problem.With the form ContactDetails, it just can't seem to read myAddValue.txtName or the others.If I try and read AddValue normally it says about it not being able to access a non-shared member (Expected that this doesn't work, it was just an attempt at something different)How do I read myAddValue from a class which isn't the one that created and isn't the one that it is an instance of?

Accessing Objects From Other Classes In ASP.NET

For instance I have a class named AbleCommerce that does some database functions. These functions are called from my main class. In those functions, however, I have no visibility of txtOutput.All of my classes are, unfortunately, in the default namespace which I understand is not optimal but didn't seem to impact this issue.

ASP.Net - Accessing Controls From Separate Classes?

Jun 23, 2010

I have an ASP.NET Web Site I am creating in Visual Web Developer 2008 Express using Visual Basic as the language. It is actually a rewrite-with-mods of an existing ASP script and I'm trying to chew what I've bitten off. I created my page with a text box (txtOutput) on it and since the end product is very complex, and it's generally good practice to separate like functions, I have created 4 separate classes in the App_Code section. My main page is Sync.aspx and has a code file Sync.aspx.vb with it. One of my code files is SyncDatabases.vb and in it I have created

Public Class SyncDB

In that class I have created some routines such as

Public Function ReadMSDB(ByVal SQLString as string) as Boolean

In this routine I want to put information in my text box txtOutput on the main form (the default - Form1).

My problem is that if I try:

Form1.txtOutput.Text = "Hello world"

or just

txtOutput.Text = "Hello world"

it says Name 'Form1' (or 'txtOutput') is not declared. I am sure I am missing something simple but have no clue what it is. I assume it's the fact that the write command is in a file (class?) outside the file (class?) containing the page itself but I don't know how to address it properly.

Asp.net - Accessing Values From Partial Classes?

Sep 2, 2011

I'm still learning so this might be completely wrong. I have built a multi-user web application for internal purposes. I have split my code up to make it more manageable and have run into some problems. I suspect that I have done something very silly!

I have a class in a separate file (quoteStatus.vb) in App_Code here it is:

Imports Microsoft.VisualBasic
Imports System.Data.SqlClient
Imports System.Data
Public Class quoteStatusHelper

[Code]...

This seems really wrong, as the value seems to be held in the partial class after the first run. So if I have two users accessing the class the public shared dim is changed for both users! There must be a better way to do this. I have looked everywhere and I'm more confused now than when I started off..How can I make QuoteStatus in the partial class unique to every user and access it from my code.

VS 2008 - Threaded Ping - Click Another Site While Its Still Pinging Them It Doesn't Wait Before It Switches Site

Feb 9, 2010

Ive got an app that holds a list of site we have, At each site there are a few devices. The idea is when they click on a site all the details for the site are loaded and then a second thread sits and pings each device to see if its live. Im trying to do this in a seperate thread so if they click another site while its still pinging them it doesn't wait before it switches site. This all seems to be workling fine except if you click through the sites quickly, when you do that it will eventually come up with

Quote:

{"Collection was modified; enumeration operation might not execute."}

The error flags up on the "Next" line in "ThreadedPing"

Thread stuff

Public Sub ThreadedPing(ByVal dt As DataTable)
Try

Dim dr As DataRow

Internet Explorer - User Click A Command Button To Open IE To A Financial WEB Site And Download Informaion From The Site?

May 19, 2011

I'm deploying a VB.Net app (VS 2010 Pro) that requiers the user click a command button to open IE to a financial WEB site and download informaion from the site. The app works fine in every detail when installed on the development computer. But, on the target computer when the command button is clicked an unhandled exception occurs which says: System.IO. FileNotFoundException:File Not found.My code behind the button is Shell("C:Program Files (x86)Internet Exploreriexplore.exe www,fidelity.com",AppWinStyle.NormalFocus)

This works fine on the development computer. Do I need a way to code this as a relative path? If so,can you tell me how this is done?Throughout the app I have written relative paths to needed files using paths like (Open(Environment. GEtFolderPath (Environment. SpecialFoldder.Desktop) + "File Name). They all work fine when deployed.

Label Staging Site To Prevent It From Being Used As If It Were The Production Site

May 18, 2012

I'm being asked to maintain several internal-only web apps for my company. For testing, after making my changes, I've created some staging sites which make use of separate databases. As such, if my users were to mistakenly use this site as if it were the production site, they may enter important data and wonder where it "disappeared" to thinking it was the production server.

I'd like to create a big banner of some sort across the top of the staging site (which ONLY appears on the staging site) to remind my users that they are on the test site. I'd like recommendations on the best way to do this, with the following considerations:

IDE: Visual Studio 2008
Server: Windows 2003 with IIS 6
Language: VB.NET 2.0

VS 2010 Structure Classes So That The User Interfaces Though A Single Class While The Supporting Classes Are Hidden From Their View?

Jun 13, 2012

How can I structure my classes so that the user interfaces though a single class while the supporting classes are hidden from their view? I think its best understood in an example:

Public Class MyInterface
Public Economic as EconomicClass
Public Sub New()
MyBase.New()

[code].....

So you might ask why am I even separating them? It's strictly for others who will be working with this interface. I need to funnel them though a logical structure:

interface.Economic.MyMethod
interface.Currency.MyMethod
etc

This way everything is already handled for them in the background and they only need to run the method they need. I don't know if I can have it both ways in VB.NET.
