This is pheraps the solution! It's Basic ! I was not able to convert in VFP.
You think it's OK ??
Some one can convert it ??

This tip was written by Chris Eastwood (www.codeguru.com/vb/) To use this tip add a form with a progress bar, a status bar and a command button on. Copy the following code into the form's General Declarations procedure:

'Declarations
'
' API Declarations
'
Private Declare Function SetParent Lib "user32" (ByVal hWndChild As _
Long, ByVal hWndNewParent As Long) As Long
Private Declare Function SendMessageAny Lib "user32" Alias "SendMessageA" _
(ByVal hwnd As Long, ByVal msg As Long, ByVal wParam As Long, lParam _
As Any) As Long

'
' API Types
'
' RECT is used to get the size of the panel we're inserting into
'
Private Type RECT
Left As Long
Top As Long
Right As Long
Bottom As Long
End Type

'
' API Messages
'
Private Const WM_USER As Long = &H400
Private Const SB_GETRECT As Long = (WM_USER + 10)


Private Sub ShowProgressInStatusBar(ByVal bShowProgressBar As Boolean)

Dim tRC As RECT

If bShowProgressBar Then
'
' Get the size of the Panel (2) Rectangle from the status bar
' remember that Indexes in the API are always 0 based (well,
' nearly always) - therefore Panel(2) = Panel(1) to the api
'
'
SendMessageAny StatusBar1.hwnd, SB_GETRECT, 1, tRC
'
' and convert it to twips....
'
With tRC
.Top = (.Top * Screen.TwipsPerPixelY)
.Left = (.Left * Screen.TwipsPerPixelX)
.Bottom = (.Bottom * Screen.TwipsPerPixelY) - .Top
.Right = (.Right * Screen.TwipsPerPixelX) - .Left
End With
'
' Now Reparent the ProgressBar to the statusbar
'
With ProgressBar1
SetParent .hwnd, StatusBar1.hwnd
.Move tRC.Left, tRC.Top, tRC.Right, tRC.Bottom
.Visible = True
.Value = 0
End With

Else
'
' Reparent the progress bar back to the form and hide it
'
SetParent ProgressBar1.hwnd, Me.hwnd
ProgressBar1.Visible = False
End If

End Sub

Private Sub Command1_Click()
'Call the function
Call ShowProgressInStatusBar(True)

'Do something in the progress bar
For i = 1 To ProgressBar1.Max
ProgressBar1.Value = i
Next i

End Sub
