Checking String List Items And Add To ListBox
Jul 6, 2011
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 have a small program that talks to a server, grabs the content from a website using a php webscraping program and then places the results in a listbox as a string. My problem is taking this string and creating a list from it. Each item in the string is followed by a | (pipe). I have included the code that I've tried below:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim str As String
Dim start As Integer = 1

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

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'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've never really used the Check List Box in the past, however, for the recent program I am developing, I am using this control rather than individual check boxes scattered across the form.Anyway, I want to be able to program through code which items get checked in this checked list box. Specifically, I have a variable that contains the text of each check box that I want checked.With a normal check box, I can simply say:
Dim strNames As String
strNames = "John Doe, Mark Johnson, Mike Brown, Cindy Smith"
If strNames.ToString.Contains("Mike Brown") Then[code]....

I have two listboxes. One for unselected bound to a datareader and one for selected. It can move all, some back and forth. I have the move buttons in an update panel and generate a report on a button click. I have this working fine. What I need to do now is color the items red or blue based on a third value from the datareader. Then add buttons to move all red >> / << or all blue >> / << Unfortunately, I can't post the code. I'm using VB.Net 2.0.

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 take the items in a listBox and post it in a textBox with a delimiter. I worked some code but it does not work correctly. I think my array is wrong but i am lost. what happening is when i click button it highlights an item in listBox and then adds it one item to the textBox x number of times of items in listBox. so if i have 4 items in listBox it adds same item 4 times. anyway here is what i have.

I have a listbox where the user can add items to it with the following schema "count, id".I want to take each item from the listbox,use the split function so I can "take" only the "count," part and then add the "count," part of each item into a string.I mean I want something like this:
user adds 3 items in the listbox:
1, 100
2, 200 and
3, 300.
I want to make it,so a string can be formed, and contain the "count," part of each item which in this case is;
in the first item the "count," part is "1,",in the second item the "count," part is "2," and in the third it's "3,".I want those "count," parts to be stored into a string (which will result into having this string "1,2,3,").

I have a listbox that gets populated with files paths based on search terms provided by the user. I want the user to be able to select multiple items on the listbox, and then be able to export the files listed to another folder. See the attached image for what I'm talking about.
The problem I'm having is that I don't know how to take the items selected and turn them into a string array. Everything else I can figure out, but this one has me stumped.

How would one code a button so upon cliking it items in listbox would sort either ascending or descending (depends on the button clicked). It mustn't be done with built-in Sort() but with a for loop for example. Tried to pseudo-code the solution to the problem, went as far as "store each listbox item in an array with a for loop".

I'm having a problem recently, a logical issue so hard to determine various examples.I need the text that is inserted in textbox, which has been altered or modified or twisted to have a proper format through line accordance and constant white spaces etc. And some cases I stuck at defining the If statement within the loop. Here's an example of a text I'm trying to reformat.[code]I'm using Microsoft Visual Studio 2010 Ultimate version with Microsoft SQL Server Management Studio. This code is being fired on mouse click event of a button control. This is a snippet of my code there are more filtering after but here is what should be changed.

I want the Function to accept List(Of String), Array & String and similarly return List(Of String), Array & String respectively. The Function simply adds a string (month) to the input collection. I just want to use it for string, array and list with needing to think of conversions.
