List Box Value Sum Up In Four Different Listbox?
Jan 13, 2010
i can currently designing a account book program. I have five listboxs..with list1,list2,list3,list4 and list5.
FOr cost: List1 is the item code and list2 will be the price..
For sold out item : List3 is the item code and list4 will be the price..
For profit : List 5 = list 2's item price - list 4's price
What i wana do is, the item tat sold out will be listed in list3, so then list3 item will be compared to list1. if list1 item contains list3 item, therefore in the same index, list3 item price (list4) will be deducted by list 1 item price(list2) and shown in list 5. here is my code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim totalitem As Integer = list3.Items.Count - 1

I am using Visual Basic 2008 Express Edition and I am trying to set a listbox so it starts to scroll when it hits the middle point of what is viewable on my list. I also want to set it so the list is always visible so you when you reach the bottom of the list you can scroll down to the bottom but if you scroll back up once it reaches that middle point it will start to scroll up again.

I'm making a program to keep track of my gaming accounts and the characters that the accounts hold. So I made a class called "Accounts", made it a Datasource to a listbox.
[code]...
So this is what I have. What I want to do, is have 2 Listboxes on my form. one Listbox contains the list of accounts, and the other contains the list of character that the selected account holds. I'm wondering how do I do this through Bindingsource? I got the Account class bound to a Listbox's Datasource, now I need to figure out how to put the List(Of Character) to the other Listbox

I'm trying to get a listbox to populate a list of processes that are neither running nor in the "blocked" list. This code is in a timer, so it also checks if the process is already in the list.
For Each proc In Process.GetProcesses
Dim allowed As Boolean = True
For Each item In Blked.Items
[Code]....
It is strange because this is populating the list, but adding the same process over and over again, even though I seem to have the checks in there.

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 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 trying to develop an application and am still learning VB. I have a commandline that will list some applications that I need to make selectable to run certain processes based on what is selected. I have already found the MSDN stuff on using the RedirectStandardOutput class to add to streamwriter. What I need to do is read each line and add to a listbox so that the user can select each application. How to read each line of the stream and add to a listbox.
Here is that code.

I have a form displayed where a user can can select a 'function' from a list box. That 'function' has a corresponding ID number which I need to be able to take and use later in the code.The List of functions is preset (about 150+ them and the IDs are already assigned (so I can't just use the index).So if the user selects "Function A", I need the code to set a variable to, for example "42" (or whatever that Funtion's ID is).
I was going to do this using listbox.item and listbox.itemData, but I'm using VB.Net in VS2008 and I understand that function is no longer present (to add ItemData at design time).Here's where it gets complicated. When the form loads it looks at the variable containing the FunctionID and if there is one present, I want it to populate the co-ordinating FunctionName. I can do that if I know the index number, but I don't know how to look at the FunctionID and return it's index (all FunctionIDs are unique).
A) store the info, either in the Listbox using ItemData, in an array (but I'd prefer to do it at design time), or some other way you might suggest.
B) cross-reference the ID and display the name in the listbox when the form loads.

I'm trying to make a program that will list all the sub-directories in a directory then list all the files in a sub directory in another listbox when you select a directory from the first listbox, what I am stuck on is listing the folders.
Dim folderInfo As New IO.DirectoryInfo("c:windows")
Dim arrFilesInFolder() As IO.FileInfo
Dim fileInFolder As IO.FileInfo
[Code]....
This code lists all the files in a directory but not the folders, I want it to do the complete opposite.

I have a ListBox containing a list of PDF files. The ListBox Click event displays the selected PDF file in a PDF control that serves as a type of preview for the user.
Private Sub lstPDFDocuments_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lstPDFDocuments.Click
If IO.File.Exists(TempCurrentDocumentsBasePath & "" & lstPDFDocuments.Text) Then Me.pdfDocuments.LoadFile(TempCurrentDocumentsBasePath & "" & lstPDFDocuments.Text)
Me.pdfDocuments.setShowToolbar(False)
[CODE]...
I want the user to select a PDF file with a click and be able to preview the document and when the user needs a larger view of a PDF file the user simply double click on the list box. When clicking on any of the ListBox items the selected PDF file is displayed in the "preview" pane. When selecting the mnuDocumentsView option from the context menu strip the new, larger, form reflecting the selected PDF file is displayed perfectly. But, when double clicking on an item in the ListBox the Click event is executed instead of the DoubleClick event. For some or another reason I cannot use both the Click and DoubleClick events on a ListBox. I've tried seperating the DoubleClick event from the mnuDocumentsView click event, MouseClick, MouseDoubleClick, but no luck.

vs2010 vb.net WPF project
This is an experiment to learn something.
I have a class called logitem
it has a datetime property, and a message as string property
I have declared myLogEntries as List(of logItem)
I have a ListBox.
Ok now what?
I have searched but i am getting lost in all the examples.
I have set the ItemsSource=myLogEntries
I think i need a datatemplate or maybe to specify binding source.
I am doing all this in the wpf form loaded event.
I guess i need a sample code for binding a list of collection to a listbox.
