Check Proxy's From Listbox?
Jun 8, 2011
So i have a listbox that i have there for a list of proxies. I have 4 buttons pertaining to it. they are find, load, save and check
I have the first 3 finished and working but i haven't found anything useful pertaining to checking the proxies, the only one that i found took like 6 seconds per proxy so it took a lot of time for a decent sized list.
So how could i make it that on the press of that button, it checks all of the proxies in the listbox and it deletes the slow ones and the ones that flat out do not work. and does this at a decent pace(so it would probably be multi threaded)
and since i can not figure this out i have no code pertaining to this except for the sub for the button click i do not feel there is a need to post code

So I am making a Proxy Clicker and I have a list box full of IP's, and that use the default port of 80. Buttons to start and stop clicking, and another list box just to display the status of the program. I want this program just to go through the list box of IPs and connect to the internet using the selected IP and the default port (80). [code] However, it gets an error after it finishes clicking the first one. When it goes to change to the second one and click it, it gives me an error saying that you cannot have 2 connections open at once. So I tried.. [code] What do I do to fix this error? What is it looking for inside the ()'s of the .EndConnect feature?

I'm making a application to use in college to retrieve my calendar and other things in VB.NET. But my college uses a proxy so when I connect my laptop I need to change the internet settings in my web browser to view web pages. how I would send requests via a proxy server in VB.NET? Or is there a piece of software that I can download which tunnels all connections or is there a setting in win7 does this?

I'd like to set the proxy for a web request. However, when I say, for example, request.proxy = "x.x.x.x:xxxxx", it gives me the error "String cannot be converted to webproxy". How can I get around this and actually set the proxy?

The user enters information into a textbox, and if it is present in the litsbox an error message will be displayed, if it is not already in the listbox then it will be added to it.
I save what the user enters as a variable and i am wondering if its possible to check the exact contents of a listbox?

Atm, i am using 'Handles lbDiscoveredDevices2.SelectedIndexChanged' where lbDiscoveredDevices2 is my listbox. I dont think this is right as if i click any blank area in the list...it runs the code, and trys to refer to highlighted items, that arnt highlighted = error.

I have a listbox, textbox, and a button. every time I push the button, an item from the listbox is put into the textbox. when the button is pushed again, it grabs the next item in order and puts it into the textbox. so on and so on until it gets to the last item. once I get to the last item it keeps repeating the last item over and over again. SO what I was wondering is how do I get a messagebox or some sort of checker to tell me when it has moved the last item from my listbox to the textbox?? PS textbox2.text=0 and every time the button is pushed another number is added to the value of textbox2.text. so basically if I could figure out how to grab the value of lines at any given time in listbox I could call a msgbox up!! here is the code I am currently using[code]...

First how do I check if each listbox item in a listbox contains an expression (Regardless of how many items there are in the listbox) and secondly how would I replace that with text that I want
So, if the First item in the listbox contained "Http%$$" then how would I change that to "Http:" without affecting the rest of the text in the item
Here is the code I have so far

I don't know what is wrong with this code, but it is not detecting when there are no items in the listbox. It ALWAYS returns that there is something in the listbox, even when there is not and keeps erroring on the line of code in BOLD.[code]

If I set a ListBox.Height = ListBox.PreferredHeight when the control is hidden and IntegralHeight = True, then set it visible:
a) Actual Height reduces by typically 3-5 pixels after redraw (but not 1 pixel per item).
b) PreferredHeight does not not appear to give the correct integral of item heights.
Is there a way to make ListBox calculate the correct integral Height before the ListBox is made visible, so it can be correctly pre-positioned from bottom edge?
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
ListBox1.Visible = False
ListBox1.IntegralHeight = True
