Change window status

Hello,
Let say I have a window (IE for instance) and I know its handle (hwnd). How can I do to change the status window:
- active window
- full screen window
- miunimized window
etc...

I know I can do it using the shell command, but my program is already running, so I can't start it with shell...
Is there some functions like setMinimized(hwnd) ????
Thx for replying

you would use the setwindowplacement api

VB Code:

Private Const SW_MINIMIZE = 6
Private Type POINTAPI
        x As Long
        y As Long
End Type
Private Type RECT
        Left As Long
        Top As Long
        Right As Long
        Bottom As Long
End Type
Private Type WINDOWPLACEMENT
        Length As Long
        flags As Long
        showCmd As Long
        ptMinPosition As POINTAPI
        ptMaxPosition As POINTAPI
        rcNormalPosition As RECT
End Type
Private Declare Function ClientToScreen Lib "user32" (ByVal hwnd As Long, lpPoint As POINTAPI) As Long
Private Declare Function GetWindowPlacement Lib "user32" (ByVal hwnd As Long, lpwndpl As WINDOWPLACEMENT) As Long
Private Declare Function SetWindowPlacement Lib "user32" (ByVal hwnd As Long, lpwndpl As WINDOWPLACEMENT) As Long
Dim Rectan As RECT
Private Sub Form_Load()
    'Tip submitted by pyp99 ([email protected])
    Dim WinEst As WINDOWPLACEMENT
    Dim rtn As Long
    WinEst.Length = Len(WinEst)
    'get the current window placement
    rtn = GetWindowPlacement(Me.hwnd, WinEst)
    Rectan = WinEst.rcNormalPosition
End Sub
Private Sub Command1_Click()
    Dim WinEst As WINDOWPLACEMENT
    Dim Punto As POINTAPI
    Dim rtn As Long
    'set the new min/max positions
    Punto.x = 100
    Punto.y = 100
    'initialize the structure
    WinEst.Length = Len(WinEst)
    WinEst.showCmd = SW_MINIMIZE
    WinEst.ptMinPosition = Punto
    WinEst.ptMaxPosition = Punto
    WinEst.rcNormalPosition = Rectan
    'set the new window placement (minimized)
    rtn = SetWindowPlacement(Me.hwnd, WinEst)
End Sub
