VS 2010 Stadium Calculator Integer?
Sep 25, 2011
This is one of my first forms so I'm sure there is quite a bit wrong with it. It works to a good degree but my issue is, Although I'm asking and checking for an int. If I put say 1.1 in a field it still lets it go. I'm sure I'm missing something very easy but I've been messing with it for hours.
Public Class frmStadiumSeatingCalculator
Private Sub frmStadiumSeatingCalculator_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I can't get the loop to work. The calculator is suppose to show how far someone goes for each hour increment (i.e. if they punch in 3 hours, it should show a number for 1 hour, 2 hours and 3 hours; if they punch in 10 hours it should show a number for 1 hour, 2 hours, 3 hours....etc. up to ten hours, etc.) I can't get it to show anything except for the total number of hours traveled and total distance.
Private Sub DistanceButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DistanceButton.Click
Dim speedIsValid As Boolean

I'm looking for a definitive, standard (i.e. certified as being correct or tested reasonably thoroughly) for calculating the ISO week from a date, in Visual Basic (i.e. to run in a Visual Studio Express 2010 Visual Basic project). I found some routines that were Visual Basic for Applications oriented; reliant on Excel environment, some things not present in Visual Studio Express 2010 Visual Basic: [URL]

I'm new in the programming area and I'm having trouble making a calculator. My question is: How do I make the calculator work using only the keyboard, without the need of mouse.
I tried this:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs)
Me.KeyPreview = True
End Sub
Private Sub FlowLayoutPanel1_KeyDown(ByVal sender As Object, ByVal e
As System.Windows.Forms.KeyEventArgs) Handles RESULTADO.KeyDown
If e.KeyCode = Keys.NumPad0 Then
[Code] .....
It only works on the text box called Result. I want to know how do I make work in the whole Class, and if it is possible, to make it work on two different Classes without writing twice the same code.

I want to make a game statistics calculator. For this I choose to make a XML database with the base stats of the characters.
I've made a small XML file in the VS2010 project with 1 class stats and made a list to 10 levels (to lazy atm to write all 85).
the XML looks like this:
<BASIC_CHARACTER_STATS>
<Levels>
<level id="1">1</level>
[Code]....
On the Form1.vb I've to combo boxes, 1 to display class names and 1 for levels.
Also have some Labels to display i.e. the base_STR number. But after trying random stuff to get it linked and closed VB to restart again because it was messed up too much

I am coding a simple calculator and I need the textbox to show the previous entries when I enter them. I hear the best way to do this is by Append Text? For example I click 3 Then + The textbox will show "3+" etcetera.

The calculator has to have the overall function of figuring the gross pay, Federal Tax Withheld (15%), and the net pay based on the hourly wage and hours worked for the week.

I have written the below code for a payroll calculator. When I run the program, it gives me my own error message box no matter if my number of hours fall within the 5-60 hours range as I have stipulated. Is there something wrong with my code?

Sweet candy store currently has a special offering of heart shaped candy. It comes in two sizes: small and large. The company sells the large one for $29.50 and the small for $16.25.Design an application to calculate how much a costumer owes. When the user clicks the "Calculate" button, the program gets the number of large and small chocolate hearts ordered from the textboxes, calculates and displays the extended price for each type of the chocolate in a label. The program also calculates the weight of the chocolate to determine the shipping cost, displays the total weight, the shipping cost and the final total due. The large chocolate weighs 4 pounds 10 ounces, and the small one weighs 2 pounds 14 ounces. Shipping cost is 35 cents per pound and 3 cents for each additional ounce. Display all dollar amounts except the final total due with 2 decimal places. Display the FINAL TOTAL DUE with a leading dollar sign and 2 decimal places. Be sure to also include a CLEAR button that will remove all inputs/outputs from the form, and an EXIT button. Define the CALCULATE button as the accept button and the EXIT button as the cancel button.

I am trying to parse several strings to integers where I both tried cINT(string) and Integer.Parse(string) but it seemed to fail at the string 'h1', I think I need to use substring for this, but as the input can be different decided by the user, it is kinda impossbile to use substring, as I do not know how to locate the integer in the string..

Just started programming with visual basic 2010 after programming a lot with vbs (Visual Basic script) it looks a lot like each other but there are a couple of differnces so here are a couple of questions.
1. What is a integer and what is a string?
2. Can i code an own sub? so it works at all times and not only when i " do something" (press a button or something like that)
for example: if progressbar1.value = 10 then msgbox " well done" now i can only add this line when i connect it to a button or something but i want to connect it to all the lines.
3. whats wrong with this line?: WebBrowser1.Navigate [URL]

Is there anyway to customize a variable to use both an integer and a boolean value?For example. I am kind of making a simulation engine and using GDI as a visual aid, I am generating a grid of tiles for objects to be displayed, but I do NOT want to repaint all the tiles just the ones that have changed, so that I can save fps.So I thought if I could set a variable for the "tile number", "how many objects there are on a tile", and a boolean value for whether or not the tile needs repainted.[code]
