I'm trying to build a small application that will automatically visit a few websites. The list of the websites I want to be stored inside a txt file like:
website1.com
website2.com
website3.com
and when I press the "Start" button, my application will open the websites from the txt file, one by one with a delay of 10 or more seconds before loading the next website, in a webbrowser control.
For Some Reason My Pop Up Blocker wont workbut if i debug the application it will work for some reason pleaerror code below:
************** Exception Text **************
System.InvalidCastException: Unable to cast object of type 'System.Windows.Forms.MouseEventArgs' to type 'System.ComponentModel.CancelEventArgs'.

Im working on an AutoUpdate class for a small application I've been working on, and with Windows 7 and Vista machines I get a permissions error when trying to replace some of the files in the Application folder. The only way to get it work is to run the application as an administrator. Is there a way I can either attempt to automatically run the app as administrator, or a way of replacing the files that won't be blocked by Vista/7's permission gatekeepers?
View 1 RepliesI currently have a browser go through the same list of sites one by one and gather updates. The problem though this takes awhile. Can a browser be multithreaded, (so it could visit several sites at a time) and if so would this take up a lot of server resources?

View 1 RepliesI'm currently using a webbrowser control to extract information from multiple websites. At any given time, my application could be searching through 1-80 different webpages across 1-4 different websites. On my computer, it runs pretty quick. I could go through all 80 sites in just a few minutes. But when on another machine with fewer resouces, it runs awfully slow. Taking up to 15 minutes. Which kind of beats the purpose, but not entirely, of my application.
I'll begin by explaining my methods, and go from there. When utilizing the Webbrowser control, I use While statements and Application.DoEvents, instead of the Webbrowser controls's DocumentCompleted event. I'm wondering if this is one thing that could be slowing down the process. Though I'm not sure why it would be. Also, would utilizing separate threads help with this? I can't imagine it would boost performance. But I'm not entirely sure. I think it bogs down because the application uses so much memory when running. On idle, the application uses about 9.5k memory. When running, I've seen it go as high as 110k.

View 3 RepliesI read some posts in the vb.net forum for how to modify your host file on your computer adding the domain website to block. this worked great. Then i went to a website such as vtunnel.com and was able to view the blocked website through it. So to still block it I need to add [url]... to the host site as well as any others?
View 4 RepliesI have the following code which sets internet explorers proxy settings to what ever i want and if i set it to use a proxy ip and port i get a 'Page can not be displayed' error. If i reset it back to the bloxx server again which is: http://gc-bloxx:8080 Then it works fine. What i am asking is, can i get the app to connect through 'http://gc-bloxx:8080' and then set the proxy ip and port so the app can connect to the internet and then unblock the websites?

I'm trying to get my program to go to the memberlist.php of a phpBB2 forum and gather all the links to the members websites.
Example: [URL]
I want the program to go to that website and save all of the websites (the ones that have the "www" image) to a list inside the program. I have no idea how to do this, but that's not all, considering most forums have several pages of members (this one has 32 at the moment) it has to go through all of the pages and gather all the links from every page..
I'm using Visual Studio 2008 on an XP machine and am trying to develop a web app that can interact with websites and carry out automatic tasks.One problem I have is trying to recreate the web requests for automatic interaction.
For example:I use a webBrowser control to allow me to surf a page manually. Then, once I am at a specific location, I'd like the automatic interaction to take over.Part of the website requires a log-in and exchanges cookie data.When I try to read the cookie info from the webbrowser control to build the subsequent automatic requests, the cookie content is incomplete.Upon further investigation, it appears that the site sets one of the cookies to "http only". This stops the value being visible to the webbrowser control.Is there another control or method I could use to retrieve this info?
What I'm working on now is a web browser. Here is what I've got for the code so far. Its Really simple.
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.Text = "Web Browser"
[Code] .....
BTW this is VB 2008 I don't know if 2010 is any different codding than 2008.
I have a task that needs to be executed many times in a thread, so as to keep my GUI responsive. Right now I'm using the ThreadPool to accomplish the tasks, and it works perfectly. I get all the data I expect back from the threads, life's good. When those tasks are finished, I then fire off another set of threads to accomplish another set of tasks, in the same fashion. The work method of these threads uses a call to RegistryKey.OpenRemoteBaseKey, which does exactly that, opens a remote registry key. The problem is: if the user running the application does not have permission to open the remote registry the call will throw an IOException, but I expect this behaviour because the user does not have permission to do it. However, the call itself can take FOREVER.
I wrote the application initially to use delegate methods and used the WaitHandle.WaitOne() method on AutoResetEvents in a state object I passed to each delegate. I tried the WaitOne method using a timeout, which worked fine until I realized that even though the WaitOne timed out, the thread was still running. This is a problem because (from what I understand) processes are only given a certain number of ThreadPool threads and, once used, they must be finished in order to be released back to the threadpool. In my work method, I also have a variable that can be signalled when the thread should be stopped, but that (obviously) only works on code that I've written.how can I cancel a thread that's stuck on a .NET method? Is there some sort of garbage collection method I can call if I give it a handle?
How do i check if specific port is blocked by Windows firewall , both in incoming and outgoing connections.
I've seen code samples such as this one:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs)
Dim host As String = "localhost"
Dim port As Integer = 6900
[Code]....
But how can i know if the exception is thrown specifically because of firewall blocking, and not because of other socket errors?
I am making a banking system in Vb.Net but I had a problem with this function. If a user fails to input the pin number for 3 times, it will be block automatically and will need the admins permission in order for that person to activate the account again. I really don't know how to code the blocking of account and asks for admins authorization to unblock the account again. By the way I'm also using MsAccess as my database for my Bank Simulation.
View 5 RepliesIm currently writing a code that can log ALL of the IP(')s that view a site. I kinda want a code that goes something like
Timer1.tick
textbox1.text = textbox1.text + loggedips.
Or something similar is fine also.After that I want the logs to be saved into a txt file, (I can do this part)Then the user will enter a new site to be logged. Once that is done that will also be saved into a txt file. Etc....Then finally if any IPS that are the same show up in the text files then the user will get that IP in a textbox.
For example I want it to go to one page then when it finishes loading go to another. So I want to to go one from one from one all with the click of a button. Is this possible?
P.S: Another question, just to kill two birds with one stone, how do I make it so whatever is written in a textbox is added to the browser url. For example if the users write 'xyz' that it will add it to Google.com/ as an example and make it Google.com/xyz?
I have a basic question about timers, that I can't answer myself. It's annoying me. My code is made to visit a website every X seconds. There are two problems.
I Set the interval for 30 sec and the first visit should be right now, not after 30 seconds.
After that, wait 30 sec and navigate to another one (in a listbox). The problem is that the Timer is not waiting that time after the first visit.[code...]
Will the elements in myList always be visited in the same order with a For Each loop (assuming I don't alter the list)?

View 2 RepliesWould it be possible to make my program visit a website and basicly filling out a text field and using the submit button in a form?For example; I have a text field named "Field" in my webpage, and I want my Visual Basic 2008 application to visit that page, and automaticly fill out that field named "Field" with a string I gave my application, and next to click on the submit button.The purpose for this is because I want that the users of my application can post feedback on my webpage. I was looking for something like a MySql client but it's best if I would encrypt/hide the protected information such as table names or MySql passwords.And I believe that these users need to have specific MySql drivers installed to use it. So this idea sounds better. So, is there a way to navigate trough a website like this?
View 4 RepliesI'm using VB 2008. I'm making a project which stores patients name, reason for visit etc in a text file using filestreaming like:
Dim fs As New FileStream("H:/ICS3U Final Project/Betolli.txt", FileMode.Append, FileAccess.Write)
Dim textfile As New StreamWriter(fs)
Is there any way the doctor can literally open up the text file by a click of a button. I don't mean like : read all lines or a STREAMREADER.I want to physically be able to open the text file which is located on the computer harddrive so the doctor can read it.
I'm having a little difficulty sending mail using VB.Net (2003). I'm attempting to use the company mailhost, and the usual System.Mail methods to do the send, but i get blocked by the "Could not create CDO.Message" error. I've been on MSDN, and looked through the various threads on here, and they all point to a problem with the dll.
The trouble is, that this is not a consistent error. Sometimes it works, sometimes it doesn't. It will work on one user's PC profile, but not another's on the same PC. It will send a mail for a particular user, and then 2 mins later fail to send the same mail. I've tried re-registering the dll anyway, and faffing about in the registry as per the MSDN recommendation, but no joy. And because it's so inconsistent it's proving pretty tricky to narrow down the cause.
i want to know how can i code my button when i click it will open my site ... i Think i was clear.
