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?
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
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?
I've got a listbox and I'm setting a default value, or so I thought, in the form load proc., but it doesn't allow me to change the value later on. It sort of sets it permanently...
I've got values 1 - 12 and I want 10 to be the default showing on the screen for the users, but I do want them to be able to choose another value and be able to retrieve it from the screen when a button is pressed.
I have a listbox and I want to loop through each of the items to see if the string im looking for is inside. I know I could do .contains but that wouldnt look at substrings. The code im using looks like this:
While tempInt > Listbox.items.count then if searchString.contains(listbox(tempInt)) then end if tempInt+=1 end while
Everything in the loop is fine but VB gives an error on the listbox(tempInt) part. The error is "class windows.forms.listbox cannot be indexed because it has no default value". get around the default value crap? I tried putting in a blank string but no change.
Im using VB2005 express and the app im creating uses the web browser control.Basically I want to know if its possible to make the web browser control connect through a different ip address and port from your default web browser.
I have been trying to create a custom control based on the ListBox called FileListBox. I followed Microsoft's walkthrough but am having some trouble.
What I want is to add another property to the ListBox called SafeItems which is an ObjectCollection of strings (like the Items property). I will use the Items property to store a collection of Filenames as strings and I would like to store the corresponding SafeFilenames in the SafeItems collection.
This is what I've tried:
FileListBox.Designer.vb <Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _ Partial Class FileListBox Inherits System.Windows.Forms.ListBox
I have a listbox on my form which gets items added as the program progresses, when there are more items than the box can display, the vertical scrollbar appears, fine... so far so good.I would like the scrollbar default position to be at the bottom of it's column so that the last entered item is displayed but can't find the relevant command, I assume there is such a command.
I'm trying to create a class for storing data on People with another class to store their Bank Transactions.Ideally, this all be hidden away and leave only simple statments, declarations and functions available to the programmer.[code]I know this is possible as these exist in the Listbox Class though can't figure out how it's done.
I have a Windows form.in windows form have a combo box that give me a list of available port serial with it code (Dim ports As String() =SerialPort.GetPortNames())for example( Com1,Com8,Com15,...).but I want to give me fullname of serial port in device manager for example in dvice manager is these (Comunication Port(COM1) - Printer Port(LPT1) And USB Serial Port(COM8)).how to Get it?
If I uninstall the COM1 and reboot, it works. If I shut down (power off) and restart, I get the message below. If I uninstall then click on Scan for Hardware Changes,The given port name does not start with COM/com or does not resolve to a valid serial port. Parameter name:portName
I am trying to get my 4 port USB relay board to work in VB.net using the COM PORT. I found some code from a poster who has the 16 port USB relay version. When trying his code i can only get it to turn on relays 1-3 all at the same time. The product can be found here: USB 4 port relay
"01+//" - Relay 1 is switched ON "01-//" - Relay 1 is switched OFF "02+//" - Relay 2 is switched ON "02-//" - Relay 2 is switched OFF
[code].....
So i am confused as to how to separate each relay out with that code above and just be able to turn on any number 1-4 relay on or off independently from each other!
I need to print the contents of 3 textboxs to default printer. what examples I have found dont seem to work. I was trying the documentprint1 component as i thought it would be easy but cant figure out how to tell it what to print the second part is to print a variable (string) to the printer as well.no need for user to select just straight to default printer with its default settings
I have a combobox which contains a sample of names selected from a table.Currently the default name displayed in the box is the 1st name found in the table. What I would like to do is display the name of the person who is doing the selection as the default. The name is stored in a public variable 'PubName' and I do not want the user to be able to type into the combobox themselves.Is this possible?

Im having problem with the Serial Port. When i run my program, "Access to the port 'COM1' is denied". What does that mean? Im not sure whats happening because theres no error in my code. Someone suggest me to use 'COM2'. Which is also the same result. I have a microcontroller, programmed and run it. And i need to capture the data onto my vb, which is on a multiline textbox. How to i do that?Just to double check my 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?

Is it possible to set a project default for VB.NET winforms projects so that the default Modifier for controls added to winforms is Private (not Friend)?I know there's a "modifiers" property in the properties window so I can set it for each individual control however I would like to change the project so from now on myself and other developers have to specifically decide to change from friend to private. (Which I would strongly discourage them from doing).I believe there is no way of doing this, but on another forum a while ago someone mentioned it would be possible with an add-in (but didn't name the add-in or where to get it).
