Getting The Website Status Using WebResponse?
Mar 15, 2009
I am trying to write a little application that will help me monitor 8 websites sharing the same IP address.
The code that I am using to query the Status of the Websites is failing to report the correct status of the website; by status of the website, I mean, if it is accessible from any browser.
I got a timer that triggers the following
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
'Create a web request for site.
[Code]....
Basically the webresponse is supposed to turn the textbox5 color to "coral" if the website is up and running or accessible, and turn the textbox5 red if the website is down. What is happening is that all the time the timer is triggered, the text box5 turns coral or "good connection" even if I entered a website that does not exist, Then after 3 minutes I get and exception error that states: The operation has timed out.
Basically, I just need a way to query the site and interpret the response by turning the textbox5 to color red in case the website is inaccessible or down.

Intended use of program:
1. User enters 1-3 websites they wish to monitor
2. User clicks go next to textbox with data entered, then button and a copy of form refered to as browse is created.
3. Form refered to as browse is directed to the url refered to on the form refered to as monitor, in the associated textbox(passed as a parameter to copyForm)
4. A timer is used to refresh the webpage every 10 seconds
What I wanted to happen was the program turn the associated picturebox in form1 green if page is loaded, and black is loading.

I would like to search an online (internet) database and import the result in my own Windows program. As I understand from reading and searching I first have to do a get from the default (search) page to get the cookies for instance and then do a post providing the filled input fields and adding the previously collected cookies. So far getting the information seems to work but submitting the data back to get the actual search result doesn't seem to work. This is what I have so far: [code]Anybody that can point me in the right direction? I my assumption correct that I first have to do a Get and then Post the correct data back?

I'd like to use the webrequest webresponse method to test for the existence of a file.If the first file is there, then I want to test for the existance of the same filename with -1.htm appended to it. If that filename exists, then test for filname-2.htm This continues until the filename being tested comes back 404 error. At which point, the program does NOT blow up, but the do until loop stops and the code continues. I have to search for a link on each one of the pages found once I have determined how many pages there are.How do I test for a file and not have it blow up? It has to loop and it goes through at least once. this is code I wrote. Right now the page just keeps going and going. IE's little logo on the page tab keep going around in a circle like it's in an endless loop.
Dim fr As System.Net.HttpWebRequest
Dim A As Integer = 1
Dim Count As Integer = 0

What I want is: To scan a website every 15 mins or so, (craigslist in this case), and email myself any new posts that come up. I know I need to use WebClient, but I never used that before. Another question would be how to only email when a new post is up and not receive the same email every 15 mins.

I have a ASP.NET 2.0 website created in C# that acts as a completely independent site and I am looking to integrate this into an existing ASP.NET 2.0 website created in VB.NET. Unfortunately I just don't know much about the server management side of ASP.NET yet so too much I'm unaware of when it comes to IIS configuration etc. Does anyone have any advice as to how I can go about integrating this? Basically I want to host it in a subdirectory from root so when you hit example.com/myindependantsite/ it will pull up my C# site.
One possible solution I came across mentioned just dropping the project folder into the root directory and setting up that directory as an application virtual directory in IIS? A few other random questions were small things like would my application relative links (~/for-example.aspx) stay relative to my root subdirectory if it's made into an application virtual directory? Just trying to get this running on their site but like I said it's completely independent so want to preserve my websites environment.

I want to create a program to fetch information from a website (that's fine). However, you need to be logged in to get this information. I just want two simple textbox controls that I would type my username and password into and hit submit and the information would be returned to me so I can use it. (I don't want to use a webbrowser control)

With my application i call an external commandline tool that converse iso's to other fileformats. Right now i just call the iso converter and it will run in the background, when you would run the iso converter via commandline you see what it is doing, but in my application it just runs in the background.
Right now it only gives me the status after the isoconverter is done in a textbox, how could i change this so i can see live status? like i would see in the command line tool?
This is the code that i'm calling to execute the isoconverter.

So, I'm running VB.net 3.5. I have a dynamic list of server names, and I want to put them in a CheckBoxList. The list is populated and, using that same list, I make a graph of the performance for each server listed. I want to be able to check and uncheck the checkboxes representing servers and, when I lick an update button, it'll create a new graph and graph only the servers that are still checked. I noticed that the page still loads before the button click is handled, so the CheckBoxList will repopulate itself before being able to read the current CheckBoxList. This is my load. And I populate my checkboxlist inside ShowView()
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Me.IsPostBack Then
[Code]....
And I wanna try to preserve the checkboxlist values when I do an event handler for an update button.
Private Sub btnUpdateGraph_Click(sender As Object, e As System.EventArgs) Handles btnUpdateGraph.Click
'insert code
End Sub

I am writing an application that calls data collectors (via ip or modem), collects data from them and reformats it. I had this much written when I was asked to make it multi-threaded so that I can collect from multiple sites at one time. I have that written using backgroundworkers and it appears to be working well. On my UI I have a text box that needs to update with status details like, dialing, collecting, reformatting, etc. I planned to simply write the status updates to the text box from an UpdateStatus routine. Found that had all sorts of nasty threading issues, so I added a delegate to call the status update routine. Problems seem to be fixed except that the updates to the UI are coming in chunks instead of one by one as they really occur. Can anybody tell me how to force the status update in the text box to update more asynchronously?
