Add a new form (frmTest) and add six command buttons (cmdBarColour, cmdBackColour, cmdDestroy, cmdCreate, cmdCreateVert and cmdSetVal). Copy the following code into the form:

Option Explicit 
  '// Stores the progress bars window handle   
Private lnghWnd As Long 
 
Private Sub cmdBackColour_Click() 
  '// Set the backcolour   
  SendMessage lnghWnd, SB_SETBKCOLOR, 0, ByVal RGB(255,255, 255) 
End Sub 
 
Private Sub cmdBarColour_Click() 
  '// Set the bar colour   
  SendMessage lnghWnd, PBM_SETBARCOLOR, 0, ByVal RGB(0,127, 0) 
End Sub 
 
Private Sub cmdDestroy_Click() 
  '// Destroy the progress bar   
  DestroyWindow lnghWnd 
End Sub 
 
Private Sub cmdCreate_Click() 
  '// Create a horizontal progress bar   
  CreateProgress False 
End Sub 
 
Private Sub cmdSetVal_Click() 
  '//Set the position to 50   
  SendMessage lnghWnd, PBM_SETPOS, 50, 0 
End Sub 
 
Private Sub cmdCreateVert_Click() 
  '// Create a vertical progress bar   
  CreateProgress True 
End Sub 
 
Private Sub Form_Unload(Cancel As Integer) 
  '// Destroy the progress bar   
  DestroyWindow lnghWnd 
End Sub 
 
Sub CreateProgress(Vertical As Boolean) 
  Dim lngType As Long 
  Dim x As Long 
  Dim y As Long 
  Dim lngHeight As Long 
  Dim lngWidth As Long 

  If Vertical = True Then 
      '// Set the style to vertical   
    lngType = PBS_VERTICAL 
    x = 250 
    y = 25 
    lngHeight = 125 
    lngWidth = 20 
  Else 
    lngType = 0 
    x = 100 
    y = 125 
    lngHeight = 20 
    lngWidth = 125 
  End If 

  '// Create the progress bar   
  lnghWnd = CreateWindowEX(0, PROGRESS_CLASS,"", WS_VISIBLE _
                          Or WS_CHILD Or lngType, 0, 0, 0, 0, Me.hwnd, _
                          0&, App.hInstance, 0&) 
  '// Set the bar's parent   
  Call SetParent(lnghWnd, Me.hwnd) 
  '// Create another window   
  lnghWnd = CreateWindowEX(0, PROGRESS_CLASS,"", WS_VISIBLE _
                           Or WS_CHILD Or lngType, 0, 0, 0, 0, Me.hwnd, _
                           0&, App.hInstance, 0&) 
  '// Move it   
  MoveWindow lnghWnd, x, y, lngWidth, lngHeight, True 
End Sub
