[mysticunicorn]

Hi all. I am new here. This site looks great. I am just starting Visual Basic.net and I am having a problem with a null reference exception. Here is my code, can someone tell me if they see what is wrong here.

First of all-- here is the error i am getting when i build my program....
*******An unhandled exception of type 'System.NullReferenceException' occurred in SportsStatistics.exe*****
Additional information: Object reference not set to an instance of an object.

*****************************
My code:

Public Class Form1
Inherits System.Windows.Forms.Form

' Declaration of Total Number of Games Constant
Const intTotalOfGames As Integer = 40

'Declare variables for team one
Dim intWins1 As Integer = Val(TextBox6.Text)
Dim intLosses1 As Integer = Val(TextBox11.Text)
Dim decWinPercent1 As Decimal = Val(TextBox16.Text)

'Declare variables for team two
Dim intWins2 As Integer = Val(TextBox7.Text)
Dim intLosses2 As Integer = Val(TextBox12.Text)
Dim decWinPercent2 As Decimal = Val(TextBox17.Text)

'Declare variables for team three
Dim intWins3 As Integer = Val(TextBox8.Text)
Dim intLosses3 As Integer = Val(TextBox13.Text)
Dim decWinPercent3 As Decimal = Val(TextBox18.Text)

'Declare variables for team four
Dim intWins4 As Integer = Val(TextBox9.Text)
Dim intLosses4 As Integer = Val(TextBox14.Text)
Dim decWinPercent4 As Decimal = Val(TextBox19.Text)

'Declare variables for team five
Dim intWins5 As Integer = Val(TextBox10.Text)
Dim intLosses5 As Integer = Val(TextBox15.Text)
Dim decWinPercent5 As Decimal = Val(TextBox20.Text)

'Define a variable for the magic numbers and games back boxes.
Dim intMagicNumber As Integer = Val(TextBox21.Text)
Dim intGamesBack2 As Integer = Val(TextBox22.Text)
Dim intGamesBack3 As Integer = Val(TextBox23.Text)
Dim intGamesBack4 As Integer = Val(TextBox24.Text)
Dim intGamesBack5 As Integer = Val(TextBox25.Text)

' Calculating winning percentage

decWinPercent1 = intWins1 / (intWins1 + intLosses1)
decWinPercent2 = intWins2 / (intWins2 + intLosses2)
decWinPercent3 = intWins3 / (intWins3 + intLosses3)
decWinPercent4 = intWins4 / (intWins4 + intLosses4)
decWinPercent5 = intWins5 / (intWins5 + intLosses5)

'Insert games back & magic number text
TextBox26.Text = "Magic Number"
TextBox27.Text = "Games Back"
TextBox28.Text = "Games Back"
TextBox29.Text = "Games Back"
TextBox30.Text = "Games Back"


'Calculating Magic Number (team 1)
intMagicNumber = intTotalOfGames - (intWins1 + intLosses1) - intGamesBack2
' Calculating games back for team 2
intGamesBack2 = ((intWins1 - intWins2) * 0.5) + ((intLosses2 - intLosses1) * 0.5)
' Calculating games back for team 3
intGamesBack3 = ((intWins1 - intWins3) * 0.5) + ((intLosses3 - intLosses1) * 0.5)
' Calculating games back for team 4
intGamesBack4 = ((intWins1 - intWins4) * 0.5) + ((intLosses4 - intLosses1) * 0.5)
'Calculating games back for team 5
intGamesBack5 = ((intWins1 - intWins5) * 0.5) + ((intLosses5 - intLosses1) * 0.5)
End Sub
End Sub
End Class

Thank you for any help you can provide...

Hi & welcome.

A couple of obvious things here.


Firstly, your post ends with 2 End Subs, but there is no beginning line for any sub.

Secondly, you have not declared any of the following;

decWinPercent1
decWinPercent2
decWinPercent3
decWinPercent4
decWinPercent5

In .NET you have to specifically declare all variables.

If that does not sort it out, find out which line is giving the problem.
