I want my program to check the pagerank of all string list items, and than add it do a listbox. Now this is my code to open a list and add it to a string list ( itemlist as list(of string)
Dim stream_reader As New IO.StreamReader(OpenFileDialog1.FileName)
Dim line As String
line = stream_reader.ReadLine()
Do While Not (line Is Nothing)
line = line.Trim()
[Code] .....
I'm using the DLL from this website: [URL]. The problem is that it only checks the first website and the other websites will be 0/10 automatically while they might be 3/10 or something else.

I am making a virtual crafting application (similar to that done in Minecraft)
currently I have made a test "crafting recipe" which checks if the listbox (mixbox) has 1 window, 1 door and 1 wheel. the code looks like this:
If mixbox.Items.Contains("window") Then
If mixbox.Items.Contains("door") Then
If mixbox.Items.Contains("wheel") Then

So I'm using the following code to add items into my list box, and I'm trying to get it to check the contents of the list box as well.
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
If ListBox2.Items.Contains(TextBox3.Text) Then
MsgBox("Character already exists!")
Else
ListBox2.Items.Add(New LBnfo With {.v4 = RadioButton6.Checked,
[Code] .....
But when I try to compare the two:
If ListBox2.Items.Contains(TextBox3.Text) Then
MsgBox("Character already exists!")
Else
It doesn't show the message box even when the character actually does exist. I believe the problem is that I never do add the item really. I just use, "Return Me.character," which is assigned the value of Textbox3. So I just need to figure out how to check Me.character before returning it.

How would one go about checking a listbox's items for duplicates? Basically I need to write a program that displays the teams from a text file provided by my instructor, in alphabetical order. I can do that, but what I can't figure out is how to prevent the For loop from adding a duplicate team. What I'm envisioning is:
If teams(i).name is not in lstTeams.Items Then
lstTeams.Items.Add(teams(i).name)
End If
I have a program that compiles and works so far, except for the above problem and my alphabetical order (which I can probably figure out on my own:
Public Class danbrockteams
Structure team
Dim name As String
[Code]....
This works except that my listbox is filled with the team every player is in rather than just listing all possible teams. Not exactly looking for someone to just give me the answer, as I understand things best when figuring them out on my own, so I suppose a hint is what I'm really after.

I am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.

I need to add items to a listbox. The listbox should have a text value that is shown to the user and a value behind that text that will be used by the code when they select an item.I can add the text for the listbox item with
ListBox1.Items.Add(ItemsTextValue)
But how do I add a value to the item?

I want to append a text file with items from a listbox. I tried to search for a code to do that, but couldn't find anything(most likely I don't know what I am looking for). But I wrote this code and got it to work, but after looking at the code, it looks sloppy and I'm sure could have bugs I didn't catch....my question is, is there a better code than the one I made, or will my code work fine. I am eager to write code correctly, not just get the code to work.

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've been trying to figure out how to do this correctly for some time now, and I have seen no insight. I'm trying to successfully save all of the items in a listbox without saving items that are not there. What I mean by saving items that are not there is when it saves, it seems that blanks magically appear in the text file.Here is a sample of my current code to save.
[Code]...
I'm not completely sure if it's the loading or the saving that's causing problems, but what would happen is it would add a blank item to the listbox that I do not want.Here's a picture before the listbox is saved, look to the bottom left.Now here is what it looks like after: (notice the red oval)Does any one have any idea what could be wrong?If you want me to attach the text file, just ask.

Several times av been come across of the need of how to create new variables on my application while is running and the next time i will run again the application to be existed in my source code and still be inside.
what excatly i mean is for example i have a listbox with out assigne it in any databound ,or retreive any items from any textbox i just want to insert some items inside
if i go from the designer then i can succesfully add any item i want and they will be there as i declare them.but if i want to to that programmatically i will be able to add them in the listbox but the next time i will run it again it will be lost.until i will select the command again to fill my listbox which is not what i want
in my case i have a datagridview which is running SQL querys and i want if the user selects to save this query i want from some way to save this query string in my listbox . and i want to be there the next time i will run my application with out using any text file or database,
is there any way to that ? i have search before i ask but obviusly my keywords dosen't much with what i was looking for

If you would indulge me here for a moment and answer a second question, how ever it has to do with an array.
I just want to know if it is possible in a single if statement to check all the items in an array
Dim times(3) as textbox
times = {adjust1, adjust2, adjust3, adjust4}
if times(?????) = String.Empty then

I have a checkedlistbox with numbers in it and I'm trying to load a list of numbers from a database and check all of them (they should all be in the checkedlistbox).
I was trying to do this by loading all the values into a separate listbox using my own subroutine (I know that part works) and then finding the corresponding item on the checkedlistbox, like this:
Dim ItemName As String
For Each item In ListBox1.Items
ItemName = ListBox1.GetItemText(item)
If CheckedListBox1.Items.Contains(ItemName) = true Then
CheckedListBox1.SetItemChecked(CheckedListBox1.Items.IndexOf(ItemName), True)
End If
Next
End If
But this doesn't work: It never returns a match, even when the item is definitely on the list. How do I make this work?

So I want it to remove any text in the list box that has a "Job" in it and just replace it with a blank nothing.
Like if the listbox looked like this
Yardjob
jobsong
redjob
then it would change it to this
Yard
song
red
I also would like a way of removing any blank items from the listbox.

Can you please help me with a button event as I would like to know how i can check the subitems in the listview when I add each subitems text in the label?
