This sub moves a rectangle to the center of the form and when it gets there it moves back to its original location. But something weird has happened and the rectangle still moves, but the boolean values dont change. I tested to see if that part of the code was executed by putting a messagebox where the boolean values are supposed to change and the messagebox didnt appear. Help would be greatly appreciated.
Here is the sub:

 Public Sub Start()
        Dim Energy As New PictureBox
        _IsMoving = True 'here is the boolean values along with some other variables
        MessageBox.Show("") 'Here is the messagebox
        _HasEnergy = False 'here is the boolean values along with some other variables
        _EnergyIndex = -1
        Do Until Not Energy.Bounds.IntersectsWith(Form1.ClientRectangle)
            If Not _HasEnergy Then
                Select Case _Index
                    Case 0
                        Rect.Location = New Point(Rect.Left + 1, Rect.Top + 1)
                    Case 1
                        Rect.Location = New Point(Rect.Left + 0, Rect.Top + 1)
                    Case 2
                        Rect.Location = New Point(Rect.Left - 1, Rect.Top + 1)
                    Case 3
                        Rect.Location = New Point(Rect.Left - 1, Rect.Top + 0)
                    Case 4
                        Rect.Location = New Point(Rect.Left - 1, Rect.Top - 1)
                    Case 5
                        Rect.Location = New Point(Rect.Left + 0, Rect.Top - 1)
                    Case 6
                        Rect.Location = New Point(Rect.Left + 1, Rect.Top - 1)
                    Case 7
                        Rect.Location = New Point(Rect.Left + 1, Rect.Top + 0)
                End Select
                For i = 0 To 9
                    If Rect.IntersectsWith(Form1.Controls("Energy" & i).Bounds) Then
                        _HasEnergy = True
                        Energy = Form1.Controls("Energy" & i)
                        _EnergyIndex = i
                        Exit For
                    End If
                Next i
            Else
                Select Case _Index
                    Case 0
                        Rect.Location = New Point(Rect.Left - 1, Rect.Top - 1)
                    Case 1
                        Rect.Location = New Point(Rect.Left - 0, Rect.Top - 1)
                    Case 2
                        Rect.Location = New Point(Rect.Left + 1, Rect.Top - 1)
                    Case 3
                        Rect.Location = New Point(Rect.Left + 1, Rect.Top - 0)
                    Case 4
                        Rect.Location = New Point(Rect.Left + 1, Rect.Top + 1)
                    Case 5
                        Rect.Location = New Point(Rect.Left - 0, Rect.Top + 1)
                    Case 6
                        Rect.Location = New Point(Rect.Left - 1, Rect.Top + 1)
                    Case 7
                        Rect.Location = New Point(Rect.Left - 1, Rect.Top - 0)
                End Select
                If Not Rect.IntersectsWith(Form1.ClientRectangle) Then
                    Form1.Lives -= 1
                    _HasEnergy = False
                    _IsMoving = False
                    _EnergyIndex = -1
                    Exit Do
                    Exit Sub
                End If
            End If
            Application.DoEvents()
            Threading.Thread.Sleep(1)
        Loop
    End Sub

Look at where the messagebox is. It's at the top of your code, meaning NONE of it is running. We need the code where you actually call this sub or else we can't help you. Make sure you actually call the sub somewhere else in your code.

Ok when I get on my computer I'll post the sub that starts this sub.

[Giver]

The sub Start is in a class called Enemy. This is the loop that starts the sub:

 Dim Threads As New Thread(AddressOf MoveEnemies)
            For Me.E = 0 To 7
                If Not Enemies(E).IsMoving Then
                    Threads = New Thread(AddressOf MoveEnemies)
                    Threads.Start()
                    Me.Text = E
                    Thread.Sleep(2000)
                End If
            Next E

This is the MoveEnemies sub:

    Public Sub MoveEnemies()
        If Not E < 8 Then Exit Sub
        Enemies(E).Start()
    End Sub

Enemies is an array of the class enemy. OK, I just figured something out. When i replace Enemies(E).Start() with Enemies(0).Start it works just fine and all the code in the sub Start is executed. But when i do that only Enemies(0) is running and i want them all to run at the same time.
