Pass integer value from one form to another in VB.NET - vb.net

Question

I'm writing a program that has two forms. One form gets the user to enter multiple values, and then does some calculations. Then it passes that information to another form However I can't figure out how to do it. Here is a relevant part of my code. To head some confusion, I am trying to pass 11 values, also initially, form 2 is not shown, and then when the values are passed from form 1 to form 2, then form 1 goes away and form 2 is the only one that shown
NOTE: This is not all my code, I don't believe all my code is required (I have 1000 lines right now) However this is the code with the information I want to be passed to the other form.
A lot of people are apparently saying that this is a duplicate of another question, however that question, he seems to already know how to pass the variables, but is just having issues with it (and even with looking at his, i cant figure it out)
Private Sub btnSubmit_Click(sender As Object, e As EventArgs) Handles btnSubmit.Click
'declarations
Dim intNormal As Integer
Dim intChildren As Integer
Dim intBonanza As Integer
Dim intDiamond As Integer
Dim intPictureFrame As Integer
Dim intKite As Integer
Dim intCrazyT As Integer
Dim intLetterX As Integer
Dim int2PostageStamp As Integer
Dim intPick7 As Integer
Dim intJackpot As Integer
Validate()
If txtNormal1.Enabled = False Then
intNormal = intNormInput
Else
intNormal = CalcNormalBooks()
End If
If txtChildren1.Enabled = False Then
intChildren = intChildInput
Else
intChildren = calcChildrensBooks()
End If
If txtBonanza1.Enabled = False Then
intBonanza = intBonInput
Else
intBonanza = calcBonanza()
End If
If txtSpecial1.Enabled = False Then
intSpecial = intSpeInput
Else
intSpecial = calcSpecialBooks(intSpecial)
End If
If txtDiamond1.Enabled = False Then
intDiamond = intDiaInput
Else
intDiamond = calcDiamond(intSpecial)
End If
If txtPictureFrame1.Enabled = False Then
intPictureFrame = intPicInput
Else
intPictureFrame = calcPictureFrame(intSpecial)
End If
If txtKite1.Enabled = False Then
intKite = intKiteInput
Else
intKite = calcKite(intSpecial)
End If
If txtCrazyT1.Enabled = False Then
intCrazyT = intCrazyInput
Else
intCrazyT = calcCrazyT(intSpecial)
End If
If txtLetterX1.Enabled = False Then
intLetterX = intLettInput
Else
intLetterX = calcLetterX(intSpecial)
End If
If txt2PostageStamp1.Enabled = False Then
int2PostageStamp = intPostInput
Else
int2PostageStamp = CalcPostageStamp(intSpecial)
End If
If txtPick71.Enabled = False Then
intPick7 = intPickInput
Else
intPick7 = calcPick7(intSpecial)
End If
If txtJackpot1.Enabled = False Then
intJackpot = intJackInput
Else
intJackpot = calcJackpot()
End If
End Sub

Answer 1

Since I had almost the same requiremnt lately here is my solution:
Custom Event which fires when your 2nd Form is closing
Public Event HotKeyFormClosed As EventHandler(Of HotKeyFormClosedEventArgs)
Custom EventArgs class where you store your values you want to pass to Main Form
Public Class HotKeyFormClosedEventArgs
Inherits EventArgs
'Your properties here
Public Sub New(...) 'your params here
MyBase.New()
'set your properties here
End Sub
End Class
On 2nd Form handle FormClosed event and pass your values to EventArgs
Private Sub HotKey_FormClosed(sender As Object, e As System.Windows.Forms.FormClosedEventArgs)
RaiseEvent HotKeyFormClosed(Me, New HotKeyFormClosedEventArgs(...)) 'your params here
End Sub
On Main Form handle your custom event (here HotKeyFormClosed) and extract its values
AddHandler frmHotKey.HotKeyFormClosed, AddressOf HotKey_FormClosed;
...
Private Sub HotKey_FormClosed(sender As Object, e As HotKeyFormClosedEventArgs)
'Do stuff with values from e
End If
I have chosen the Event approach since it decouples the two forms from another.
One could easily duplicate the information on both forms, make them public and access it directly thru an object instance.
But I like the observable approach from the events more due to it gives mor flexibility (additonal forms using the same events etc.)
P.S.: I wrote my code in c# and blind entered the VB code here so be gracious.

Answer 2

The values/variables that a method expects to receive (specified in the method's signature) are called Parameters.
The values sent to a method when the method is called are called Arguments.
As long as the arguments used when calling a method match the parameters for that method, those values can be passed.
For example (and I'll try to apply this to your context), if you want to create an instance of a form that takes certain values, you can specify those parameters in the form's New event, like so:
Public Sub New(someInt As Integer)
'do something with someInt here
End Sub
Then when you call this method you'd pass it the arguments, like so:
Dim myInt As Integer = 10
Dim newForm As myForm = New myForm(myInt)
When I say the arguments need to match the parameters, that means the number of values, the order of those values, and the value types must be the same (or in the case of numbers the parameter's type must be the same or larger than the argument's type).
As long as that is true, then it shouldn't really matter how you pass these - you could pass 11 individual arguments, you just have to make sure you are matching the argument to the parameter.
Hope that helps!
