[2008] Counting Numbers From A Listbox In A Richtextboxbox?
Jan 22, 2009
I have a problem with my code.
first code
Private Sub BtnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnToevoegen.Click
Dim bytSum As Byte
Dim bytTotal As Byte
[code]....
I have a listbox with the numbers from 1 to 20 in it. If I add one of these 20 numbers, the number should be added in the richtextbox and they should be counted together with the last outcome I had. And this new outcome should be shown in label "lblTotal. If I add a new number into the richtextbox with this button. This new number should be added under the last number in the richtextbox and it should counted with the last outcome I had. This way I can count how many points I have.

Im just trying to get a simple multi line label box counting numbers using vbCrLf.
Dim startNumber As Integer
For startNumber = 1 To 4
lblCount.text = "Number = " & startNumber & vbCrLf
Next startNumber
I just want something to display like this in a multi line label, not a textbox:
Number = 1
Number = 2
Number = 3
Number = 4
But... I keep getting something like:
Number = 4
I already turned auto size off and expanded the label.

I have a single listbox that stores data from a saved .txt file. All of values are whole numbers and I'm trying to add together all the items in the listbox (the numbers) and then display them in a textbox. I have searched, and tried several things but each time I try to add them together, it states that my items are strings. How to sum listbox items and/or convert them out of strings?

I am making a Bingo game. I have a button which keeps on calling numbers which are then added to a list box. How do i make it that the numbers called don't repeat (get displayed in the "number called" label). Is there a way to use items already added in the list box to eliminate duplicate numbers.

The List Box has three candidates and a record Button. Every time the record button is hit I need it to add those button clicks for each candidate that is selected in the List Box. My code keeps counting all the clicks no matter which candidate I am selecting in the List Box. How can I differentiate between each selected item in the List Box.
Private Sub exitButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles exitButton.Click
Me.Close()
End Sub

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

I've done what I thought was a lot of work with DateTime and Timespan but what I am trying to do now I cannot figure out. It seems simple enough but I can't think of the code I need to make it work >.<
Currently I am using a timer to tic on 1000ms to count down a timespan. However, what I would like to do is set a timer for 30 minutes. I would like to display the minutes:seconds of the timer on a label and perform actions when the minutes and seconds are specific values, say minutes = 5 AND seconds = 0 to perform an action when the timer reaches 5 minutes exactly.
My goal is to have a 30 minute timer that performs actions at specific times, then when the timer reaches 0:00 it restarts at 30:00 This seems like such a simple task but I cannot for the life of me figure out where to start.

Inside one of my functions, i load up an xml then retrieve the relevant data like:
vb.net
'// load up all the fields we will need to work with
Dim firNam As String = XMLItem("hiddenFieldsName0").InnerText
[Code].....
Don't exist, i was wondering if there was a way to check how many lines there is in the xml and then load them? or is there an easier way i could do this?

I am stuck again. I have an Access database file which list all the players for a baseball team. The player age range is from 12 to 14. I need to be able to click a button to count how many players are in each age group and dispaly that information in three separate labels. One label for each age group.
I have learned how to count rows, but how do I count rows containing certain data like 12, 13 or 14. I also know and understand how to get information to display in a label. I need to know and understand how to count just certain records.

I am in a "survey of programming languages" course and have a professor who doesn't teach. There is no text book for this course.I am working a VB Form project to take a URL, grab the HTML source code, parse out all words, and count the occurrences of each word on the page. I have built the form, and written the code to parse the words and store them in an array. What is the most efficient way to count the occurrences of each individual word in that array (case insensitive), sort the results decreasing from most frequent, and display the results of the ten most used words. I will be displaying the results in two separate listboxes on my form. 1 listbox shows the words, and the other shows the number of occurrences.

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

This is my first time posting in a forum like this, so please excuse me if I accidentally break any thread rules (btw, where can i find these?). I am very new to Visual Basic and have been trying to teach myself as I create this program. I have experience with macros in excel so I do understand some of the coding, but definitely nowhere near being proficient. I am using Visual Basic 2008 Step by Step (Michael Halvorson) to teach myself.
I am trying to create some code in my program that will allow the user to open an excel file and then return the number of rows and columns in the worksheet. There will only be 1 worksheet in the workbook (since this is just a small part of a larger program I am writing). I already tested the code that will open the file in another program and it worked fine; the thing that is catching me is the row and column counts. I'm a bit stuck here and was hoping someone could point me in the right direction. Here is the code as follows: Code: I have another sub for a quit button which I chose to leave out. The last line for the MessageBox is causing me problems.
