Hi Everyone!

I have been experiencing problems in displaying my varibable Gcoins in form3 from form1.

here is what i have in my form3 code.

Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim frm1 As New Form1
        Dim points As Integer
        gcoinsamount = Val(frm1.Label2.Text)
        Label1.Text = gcoinsamount.ToString
        points = Val(Label1.Text)
        Label2.Text = points.ToString("N")
        frm1 = Nothing
    End Sub

and here is the codes in form1. (Kinda messy)

Public Class Form1
    Dim rnd As New Random()
    Dim value1 As Integer = Rnd.Next(1, 3)
    Dim value2 As Integer = Rnd.Next(1, 3)
    Dim timercount1 As Integer = 80
    Dim scorepoint As Integer = 100
    Dim GcoinPoints As Integer = 50
    Dim gcoinpoints2 As Integer

    Private Sub form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
       
        Timer2.Interval = 1000 'The number of miliseconds in a second
        Timer2.Enabled = True 'Start the timer

        Label2.Text = GcoinPoints.ToString
        RichTextBox1.Text = scorepoint.ToString
        
        Dim frm2 As New Form2()
        If (frm2.ShowDialog = Windows.Forms.DialogResult.OK) Then
            UserNameLabel.Text = frm2.UserNameTextBox.Text 'which displays the username onto the label'
        End If
    End Sub
    Public Function FindGcoins(ByVal gcoinpoints2 As Integer) As Integer
        'Calculate the amount of Gcoins

        Return scorepoint / 2
    End Function
    Private Sub Button1_MouseEnter(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.MouseEnter
        ' User moves mouse pointer over the button, change the color
        Button1.BackColor = Color.Yellow
       
    End Sub

    Private Sub Button1_MouseLeave(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.MouseLeave

        timercount1 = 80 'Reset to 80 seconds
        lblOutput.Text = timercount1.ToString() 'Reset the output display to 80
        Timer2.Enabled = True
        gcoinpoints2 += -20

        If value1 < value2 Then
            Label1.Text = "You win"
            MessageBox.Show("You win")
            scorepoint += 40
            gcoinpoints2 = FindGcoins(gcoinpoints2)
            RichTextBox1.Text = scorepoint.ToString
            Label2.Text = gcoinpoints2.ToString()
        End If

            .Focus()
        End With
        timercount1 = 80 'Reset to 80 seconds
        lblOutput.Text = timercount1.ToString() 'Reset the output display to 80
        Timer2.Enabled = True
    End Sub
End Class

The problem is that when ever i get into form3, it won't display my value Gcoins in the label i want.

Any one can give my some solutions to this?

Thank you!!!

On Form1 you are declaring your variables "Locally", therefore only Form1 has access to them.

To declare something "Globally" you need to change "Dim" to "Public".
Example of a "Global Declaration" on Form1:

Public Gcoins As String = "1,000,000 gazillion & a couple billions."

And to get the variable from another form, I used the following:

Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        MsgBox(Form1.Gcoins)
    End Sub
