I am able to only move single items from one listbox to another with this code. I tried with both MultiSimple & MultiExtended SelectionMode.
How do I select multiple items and then move them?

I am currently working on some tools and I am having some troubles adding new lines in a listbox.
vb.net
For i = 0 To lstFiles.Items.Count - 1
Process.Start("C:UT2004Systemucc.exe", "compress " & lstFiles.Items.Item(i))
If IO.File.Exists(lstFiles.Items.Item(i) & ".uz2") Then

The meaning of this code is that if the file exists, it will add a new line called Success below the dragged fileline. If the file doesn't exist it will create a new line called Fail below the dragged fileline.

View 2 RepliesI 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 start As Integer = 1

i'm creating a web form and i want a user to be able to make certain selections and then add the selections to a text box or listbox.Basically i want them to be able to type someone name in a text box ... check some check boxes and for it up date either a text for or a list box with the result on button click...
e.g.
John Smith Check1 Check3 Check5
I have this code to add Items to a Listbox:
Private Structure Bets
Public id As Long
Public name As String
Public size As Double
[code]....
I googled to find how I can change the items forecolor or backcolor. I want the items containing "Unmatched" to be one color and "Matched" another.
We have a button, textbox and a folder browser... We made it so that when you click the button it shows the folder browser dialog.. And you choose your folder/path, then it shows the selected path in textbox.. We are succesful on this.. But now weve added a listbox, And when you selected the path it will do this..

I am trying to be able to add everything within a listbox to a program setting that can be re loaded when its opened up again, I have the part to load them upon opening, but I don't know how to make it add all the items within the listbox to the setting, so it has something to load.
This is to load them on startup:
For Each item As String In My.Settings.logs
log.Items.Add(item.ToString)
Next
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.
I want to manually add two items as "Active" and "Inactive" in a ListBox. When the user selects "Active", I want to get the value "A" and when "Inactive" is selected, I want to get "I". How do I do this in VB.NET.
View 3 RepliesHow 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 got 3 listboxes.

So basicly I want to loop all items from listbox1 with each item in listbox2.
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

I've looked everywhere on the internet for multiple items drag&drop between listboxes and found only examples showing single item drag. I know how to make a single item dragdrop operation between two listboxes using MouseDown, DoDragDrop, DragEnter, DragDrop Now what I'm looking forward to learn is the ability of dragging more than one item from one listbox and dropping them in another listbox
View 2 RepliesI currently have two list boxes that have the exact same items in each. I don't want the user to be able to select the same item from both list boxes.
My code:
listbox1.Items.Add("SSS")
listbox1.Items.Add("AAA")
listbox2.Items.Add("SSS")
listbox2.Items.Add("AAA")
I'd like the user to not be able to select AAA & AAA from different list boxes, just SSS & AAA. I have way more items just thought I'd shorten it.
I want to delete Multiple rows of listbox, I tried this

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.
basically i had this problem before which i fixed with this code!

It worked perfectly, all ive done to my code since is change the way the listboc is loaded / saved, it now comes from a .txt in My Documents rather than the C drive.
It now only deleted the top value of the group selected int he listbox and not all of them as it did before.
I know that I can select an option in a listbox within my HTMLDocument (which refers to a webbrowser control's HTMLDocument) using SetAttribute. For example:
htDoc.GetElementById("lstCountries").SetAttribute("value", "88")
However, I can't figure out how I can select multiple items within the listbox. When I call SetAttribute repeatedly, it always unselects the old one first.
I have a combo box with a list of Coordinator IDs, one Coordinator can run many subjects. On another form I have a list box that contains a list of the subjects, and another list box that has the coordinator that teaches the subject. The positions match up, i.e if there is a match for the co-ordinator ID in the list box at position 3, I want to extract the subject list box at position 3 also. The problem is 1 coordinator can teach more than 1 subject. Basically I want to show the subjects taught by the Coordinator the user selects in the combo box. I have tried the following but have had no luck:
