Below are the guts of my program, I need to somehow get the results of my calculations with the code below on frmMain to be displayed in frmDisplay in a listbox named ListBoxDisplay. I have commented my code so it's easier to understand. Any code help is appreciated.
VB.NET:
Public Sub btnGenerate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGenerate.Click
Dim i As Integer
Dim j As Integer
Dim results() As Integer
Dim output As String
ListBox3.Items.Clear()
'Get known
Dim known As ListBox
known = knownValuesList
'Array keeping the results
ReDim PResults(numPlays.Value, numsPerLine.Value)
For i = 1 To numPlays.Value
results = getNumbers(known, numsPerLine.Value, minRange.Value, maxRange.Value)
For j = 0 To results.GetUpperBound(0)
PResults(i - 1, j) = results(j)
'Can change the "0" to " " to use a space
Dim temp As String = IIf(CheckBox1.Checked = True, String.Format("{0:00}", results(j)), CStr(results(j)))
If output <> "" Then output += " - "
output += temp
Next
' This section used with ListBox3 on same frmMain and not using frmDisplay
'ListBox3.Items.Add(output)
'output = ""
Next
'open the form and populate ListBoxData's listbox to display the results.
Dim frmDisplay As New frmDisplay
frmDisplay.Show()
End Sub
Public Function getNumbers(ByVal known As ListBox, ByVal requiredNumber As Integer, ByVal minRange As Integer, ByVal maxRange As Integer) As Integer()
Dim output() As Integer
Dim i As Integer
Dim tmp As Integer
Dim rndIndex As Integer
Dim tmpArray(requiredNumber - 1) As Integer
Dim randomPool As New ArrayList
' build the random pool
For i = minRange To maxRange
' don't include any of the known values
If Not known.Items.Contains(i) Then
randomPool.Add(i)
End If
Next
' shuffle the random values
For i = 0 To (randomPool.Count - 1)
rndIndex = R.Next(0, randomPool.Count)
tmp = randomPool(i)
randomPool(i) = randomPool(rndIndex)
randomPool(rndIndex) = tmp
Next
' populate tmpArray with the known values
' and fill in any remaining slots
' with values from the shuffled randomPool
For i = 0 To (requiredNumber - 1)
If i <= (known.Items.Count - 1) Then
tmpArray(i) = known.Items(i)
Else
tmpArray(i) = randomPool.Item(0)
randomPool.RemoveAt(0)
End If
Next
' shuffle the set by swapping
' each position with another
For i = 0 To tmpArray.GetUpperBound(0)
rndIndex = R.Next(0, tmpArray.GetUpperBound(0))
tmp = tmpArray(i)
tmpArray(i) = tmpArray(rndIndex)
tmpArray(rndIndex) = tmp
Next
output = tmpArray
Return output
End Function
Private Sub CheckBox1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
Dim i As Integer
Dim j As Integer
Dim output As String
Try
ListBox3.Items.Clear()
For i = 0 To numPlays.Value - 1
For j = 0 To numsPerLine.Value - 1
Dim temp As String = IIf(CheckBox1.Checked = True, String.Format("{0:00}", PResults(i, j)), CStr(PResults(i, j)))
If output <> "" Then output += " - "
output += temp
Next
ListBox3.Items.Add(output)
output = ""
Next
Catch
End Try
End Sub
