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'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 have this code to check if an item from a textbox is in a listbox and its giving me the error at the bottom.I copied it from another part of my project and it was working for that part so I cant see whats wrong.
If LocationsSearchTextBox.Text <> "" And LocationListBox.Items.Count > 0 Then

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 line As String
line = stream_reader.ReadLine()
Do While Not (line Is Nothing)
line = line.Trim()

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.
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 5 checkboxes in total.I want to check how many checkboxes have been checked.I dont want to write checkbox1.checkstate,checkbox2.checkstate and so on...How do I accomplish this effectively?
View 1 RepliesI have a question here.. pls kindly advise.I need to design a simple form that allow user to choose the value from Listbox A to Listbox B. For example, in Listbox A, have value A, value B and value C, then user can choose (or highlight value B and value C) and copy into the listbox B.
May i know how can i do this in vb.net? Any reference link?
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 got 3 listboxes.
[Code]...
So basicly I want to loop all items from listbox1 with each item in listbox2.
I 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
For teller = 0 To 170 Step 1
ListBox1.Items.Remove(teller)
Next
But that doesn't work. How do I delete the first 170 rows in my listbox? :)
i want to be able to remove multiple listbox items using one button the code i have tis the following: [code] Now this removes one item from a listbox, i changed the selection mode now now i can select multiple listbox items, but how does the code differ to delete all of the items selected? As currently it just deletes the top of all the selected items!

View 3 RepliesI 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.
basically i had this problem before which i fixed with this code!
'REMOVE TIME
If ListBox1.SelectedIndex <> -1 Then
Dim Box As MsgBoxResult = MsgBox("Are you sure you want to remove this time?", MsgBoxStyle.YesNo)
[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 have a listbox on my form, and a procedure that scans a certain directory for sub-directories, it then adds each subdirectory as a item in the listbox.
ex :
g:movies2010Clash of The Titans
g:movies2010Date Night
g:movies2010Red Dawn

I remember in the old VB6 that there was something simple as listbox.add("my string", 1 This '1' would meant the position I want it to be added, which means 'the top'I'm sure it sounds newbie... but hey, what a heck... I'm only been programming .net for a few months.
View 3 RepliesI 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:

I have a listbox that allows a user to have multiple selection and a button to transfer these selected items to another listbox, now theres a new requirement which I also need to indicate the quantity for each respective items. I currently have a Source items select box and a Selected items select box. how to go about designing this feature?
Multiple select box selected Quantity
E.g. Eggs ---> Eggs ---> X 4

I am trying to display multiple check items from a listbox into a label seperated by a comma. Everything is working fine but the only problem is that when i check first item in the listbox nothing happens and when i check the second item then the label shows the first item. Then when i click third item the label shows the first and the second item and so on. When i uncheck the item it does the same
My question is why it does not show the items in the label as they are selected.

this code works fine as long as i dont remove ALL items, the error i am getting is index is out of bounds of the array, i have tried -1, -2 0 +1 +2 and all are still giving this error, i cant just create code for remove all as i wont always need all removed so i kinda of have to get this code or something similar to remove only checked items. the code below is code i have tried

I'm using the following to add a list from a txt into a listbox, which works perfectly.
Dim OFD As New OpenFileDialog
OFD.Filter = "Text Documents (*.txt)|*.txt"
OFD.Title = "Open List"
OFD.ShowDialog()
ListBox1.Items.AddRange(IO.File.ReadAllLines(OFD.FileName))
The similar thing below does not work to load sites from the clipboard. What else could I use.
ListBox1.Items.AddRange(IO.File.ReadAllLines(Clipb oard.GetText))
I am adding an object to a Listbox which has the properties "ID" and "Text". I have set the "DisplayMember" property of the Listbox to "Text" and "ValueMember" to "ID".Everything works fine when I add a new item to the list, but when I edit the item and change the "Text" value, it is changing in the object but the Listbox still just showes the original value.I have tried calling ".Refresh" and ".Update" to see if they worked, but made no difference.I usually use VB6 for prototyping programs but decided to use VB.NET for this one. Did not realise VB.NET got shot of the "ItemData" property in the ListBox control.
View 3 RepliesI 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.
