i have created a module here is the code for module file

Module Module1
    Public Sub bknapper()

        'create button on fly
        Dim intLoop As Integer
        Dim rand As New Random
'genrate array that will get the random values from c variable and 
'will use to compare if the value is unique
        Dim kontroll(49) As Integer
        ' Off sets 
        Dim y As Integer = 65
        Dim x As Integer = 0
        Dim a, b, c, d, e1 As Integer
        a = 1
        b = 10
        ' Loop through buttons 
        For intLoop = 0 To 24

            ' Create button and set its width 
            Dim newbutton As New CheckBox
            newbutton.Appearance = Appearance.Button
            newbutton.TextAlign = ContentAlignment.MiddleCenter
            newbutton.Width = 40
            newbutton.Height = 40

            ' If we have hit 4 buttons, adjust the y value by adding 10 onto the controls height 
            ' Reset x back to 0 
            If intLoop Mod 5 = 0 Then
                ' This gives us a 10 pixel buffer below each row of buttons 
                y += newbutton.Height + 1
                x = 0
            End If

' give random value rage 
'first line will show random values between 1 and 10
'second line will show random values between 10 and 20
'and so on
            Select Case intLoop
                Case 5
                    a += 10
                    b += 10
                Case 10

                    a += 10
                    b += 10
                Case 15

                    a += 10
                    b += 10
                Case 20

                    a += 10
                    b += 10
                Case 25

                    a += 10
                    b += 10

            End Select
            'genrate random values and save that value in variable c
            c = rand.Next(a, b)
            newbutton.Text = c

            'check if the randomize value is unique if not give that another random value and check it again
            For d = 0 To 49
                If kontroll(d) = c Then
                    c = rand.Next(a, b)
                    newbutton.Text = c
                Else
                    Dim d1 As Integer
                    For d1 = 0 To 49
                        If kontroll(d1) = c Then
                            c = rand.Next(a, b)
                            newbutton.Text = c
                        End If
                    Next

                End If
            Next d
            'assgin all random c variable values to an array of integer "kontroll"
            kontroll(intLoop) = c
            newbutton.Top = y
            ' This gives us a 5 pixel right buffer between buttons 
            newbutton.Left = 350 + (x * (newbutton.Width + 1))
            x += 1
            Form1.Controls.Add(newbutton)
        Next
    End Sub
End Module

and what i want when i press the button on form1 it will reload and show new random numbers on that buttons and code for form 1 is here

Public Class Form1


    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Randomize()
        bknapper()
    End Sub

    Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
        Form2.Show()
    End Sub

    Private Sub AvslutaToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AvslutaToolStripMenuItem.Click
        End
    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Form1_Load(Me, New System.EventArgs)


    End Sub
End Class

can any one help me.. or tell me the logic what i am doing wrong.

>How to reload method form module.

I guess you want to call a method. Isn't it?

[iman_shani]

yes but what is the syntax and what i am doing wrong. i just want to recreate buttons on fly and asign them again the new random values.
i have tried on form_reload,
bknapp() to recall this method/sub procedure on button_2 click event.
but nothing happens

[kvprajapati]

You have to call that method in button click event handler.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Me.WindowState = FormWindowState.Maximized
        Randomize()
        bknapper()
    End Sub

i am still getting the same problem..
is that another way that i can solv this issue?

You have to remove all checkboxes from the controls collection before adding new.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        For Each ch In Me.Controls
            If TypeOf ch Is CheckBox Then
                Me.Controls.Remove(ch)
            End If
        Next
        
        Randomize()
        bknapper()

    End Sub

Thanks for effots i fixed the problem with the other way
what i did that i just created the buttons on fly on form load and on button_click event i genrated the random numbers and assign these numbers as text to the buttons.
