Sum Numbers In Listbox - Add All Numbers Together And Display The Result In A Label

Jan 10, 2010

I'm using VB08. I've populated a listbox with numbers and I want to add all those numbers together and display the result in a Label. I've heard about using parse but I don't understand exactly how it works.

This is the code that I have that i think should work.

Dim lblTotal As Decimal
Dim sum As Double
For Each decAdded As Decimal In Me.lstRunningTotal.Items
sum += Double.Parse(decAdded)
Next
lblTotal = FormatCurrency(sum)

When I run it, nothing happens. My "For Each" statement I'm not sure if it's doing what I think it's doing. I can't believe I spent 6 hours banging my head against the wall but I finally got it figured out.

This is my revised code:

Dim sum As Decimal
For Each decAdded As Decimal In Me.lstRunningTotal.Items
sum += Decimal.Parse(decAdded)
Next
lbl_Total.Text = sum

Just some suttle changes made the difference

Even Numbers Listbox Display?

Dec 1, 2010

The program must display numbers 0 to the highest number entered into one of the textboxes which are even division of bigger number by smallest number.The program isn't quiet done, but I have the rest of it figured out.The problem is that for some reason the program won't change the label status text and display numbers in the listbox if number1 is negative and number2 is positive. But if number2 is -10 and number2 is 3 it works. Also it ignores any other If statements I made.

Public Class Form1
Dim number1, number2 As Integer
Private Sub btnExecute_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExecute.Click
If (Not (IsNumeric(txtFirst.Text))) Or (Not (IsNumeric(txtSecond.Text))) Or (txtFirst.Text = Nothing) Or (txtSecond.Text = Nothing) Then

ListBox PreferredHeight - Make ListBox Calculate Correct Integral Height Before ListBox Is Made Visible

Nov 19, 2009

If I set a ListBox.Height = ListBox.PreferredHeight when the control is hidden and IntegralHeight = True, then set it visible:

a) Actual Height reduces by typically 3-5 pixels after redraw (but not 1 pixel per item).

b) PreferredHeight does not not appear to give the correct integral of item heights.

Is there a way to make ListBox calculate the correct integral Height before the ListBox is made visible, so it can be correctly pre-positioned from bottom edge?

Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

ListBox1.Visible = False
ListBox1.IntegralHeight = True

Displaying All Prime Numbers In ListBox

Mar 13, 2010

I am suppose to write a program using if statements and loops: Create an application that reads an integer number from the user and then displays in the List Box all prime numbers (for this project we are going to violate "positive" rule and make our prime numbers be negative as well) between user's number and zero 5 numbers in one row. The application also displays how many prime numbers there are between user's number and zero, and the total sum of all these prime numbers.

Removing Duplicate Numbers In Listbox?

Jun 10, 2011

I have been working on a pythagorean theorem calculator and am actually stuck on the final bit of code. What I am trying to do is check the values (integers) inside a listbox, remove duplicate number (both values), and input one of the values into a textbox.

Here is an example of what I am doing:

LISTBOX VALUES
2
2
3

[code]....

When the program runs, check listbox value #1 and listbox value #2, if listbox value #1 and #2 match (2 & 2), input that value (not both duplicates) into a variable, remove both of the duplicate values, continue checking the rest of the values, and finally multiply the leftover values. I am sure that sounds confusing. Here is what the final output will look like

LISTBOX VALUES
3
7

Changing A Label Value Based On Selection In A Listbox?

Just wondering if someone can at least point out where I'm going wrong here. I've already got the code to populate the listbox by a button click from the user and am just trying to figure out how exactly to alter the text of a label based on what the user selects in the listbox. From what I have the Label will display the case else selection but nothing else despite my best efforts to get it to change. Here is what I've tried. I realize it is very trivial, but I am only a beginner to programming.

Listbox Items Colour - Two Types Of Items Populating In A Listbox (checked Listbox)

Apr 28, 2009

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.
