i'm trying to do a workshop selector that adds price of each workshop selected and puts the type of workshop the place and the total price then adds the sum of all workshops together.i'm trying to figure out how to extract only the price from the last list box and add them to get the final sum and display in a text box. I have a loop to add it but it only works when the workshop and place is not in the listbox.

I would like to be able to extract a number from within a string formatted as follows:
"<[1085674730]> hello foo1, how are you doing?"
I'm a novice with regular expressions, I only want to be able to extract a number that is enclosed in the greater/less-than and bracket symbols, but I'm not sure how to go about it. I have to match numeric digits only, but I'm not sure what syntax is used for only searching within these symbols.
I was wondering why some of the implementations were not working. In fact, the only one that did work was the one described by Matthew Flaschen. But that captures the symbols around the number as well as the number itself. I would like to only capture the number that is encased in the symbols and filter out the symbols themselves.

How to sorting number in Listbox.
View 10 RepliesOk this is what I'm stuck on:I have 2 ListBoxes and 2 Lists, let's call them ListBox1, ListBox2, List1 and List2.List1 needs to be associated with ListBox 1, and List2 with ListBox2 I loop through a bunch of accounts, add them to LixBox1 at run-time.During that loop I add each account number to List1 so now the account number is associated with the ListBox index number which is right.Now when I double click one of the accounts in ListBox1 it is added to ListBox2 (but it still remains in ListBox1), and the same index of List1 added to List 2, now the account in ListBox2 is associated with the account number at the same index in List2 you see where I'm going with this?The issue wtarts here.When I double click an account (let's say the account at the first index) in ListBox2 it should be removed from the list, so now I remove the index from List2 since it's no longer needed, but now you know what's happened right? ListBox2's List indexes have all decremented by 1 because I just removed an item from the beginning of the list, but List2's indexes have stayed the same (at least that's how it appeared when I tested it).
So basically whats the best method for keeping things in reference? I was told about list boxes in another thread of mine, but is it really the best way to go about this, I can't seem to keep everything linked together reliably.
I have a listbox, textbox, and a button. every time I push the button, an item from the listbox is put into the textbox. when the button is pushed again, it grabs the next item in order and puts it into the textbox. so on and so on until it gets to the last item. once I get to the last item it keeps repeating the last item over and over again. SO what I was wondering is how do I get a messagebox or some sort of checker to tell me when it has moved the last item from my listbox to the textbox?? PS textbox2.text=0 and every time the button is pushed another number is added to the value of textbox2.text. so basically if I could figure out how to grab the value of lines at any given time in listbox I could call a msgbox up!! here is the code I am currently using[code]...

View 4 RepliesI am trying to use a listbox to hold categories from one table in a database and by clicking on the categories in the listbox it will display data from another table in the database that is linked to those categories. One table has a field called ID and the other has categoryID and categoryID is linked to ID so it displays the numbers from ID.I am using this:
daSamples.SelectCommand.CommandText = "SELECT * FROM tblSamples WHERE tblSamples.categoryid =" & (lstCategory.SelectedIndex + 1)
daSamples.Fill(dsSamples, "tblSamples")
Currently, however with this if you delete a category from the table with ID in it then it changes the values of the selectedindex in the listbox which messes up the data that gets displayed. How can i change this so instead of using the selectedindex from the listbox, it takes the ID from the selectedindex?
need a program that will display the even numbers from 1 to 100 in list box.
View 11 RepliesI've got a question about Listboxes in Visual Basic 2008 Express. I have a fair bit of experience with Office (both 2003 and 2007) and use the listbox in office all the time. The thing I like most about it is the ability to set the number of columns so I can have a string for the user to see and a second column of 0 width that holds my ref number.
So when I needed to do the same thing in VB 2008 Express I grabed the Listbox control and.....hit a brick wall. As far as I can find out from the help files and searching the web the Listbox control only shows one column really. Ok so it might wrap to a second column to save the user having to scroll but its still basically one column. There seems to be no way of having something like in Office.
I know I have no code, but I don't have any code for this. I'm just asking in case I'm missing a control or something obvious. Hell at this point I'm almost tempted to create my own Listbox control that acts the way I need but thought I'd ask before heading down that route.
i have 1 button, 1 listbox and 1 textbox.this is my code
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
ListBox1.Items.Clear()
Dim finish As Integer = TextBox1.Text
[code]....
if i set the sorted property of listbox1 to true that code will add 0 before the inputted number so that the sorted property in listbox1 will be usefull in sorting integers.
for example i have 1,15,30,36
it will make 001,015,030,036
thats what i think am not sure because i cant edit the code so that it will work in my program.
I have built a system for a shipping company to use that takes user input from various sources (Textboxes, RadioButtons etc) and displays it in listboxes below. What I need to do is create individual shipping numbers for each of the consignments added based on certain criteria, that being:When adding a consignment, the system should generate the consignment number automatically in the format XY12-xAB, where x is a number that increases by 1 for each consignment, AB is the Shipment Type (EA, SA or SF) and XY12 is the Office ID.
So far, I have this:
Private Sub GenerateConsignnmentNumber()
Dim sConsignmentNumber As String
