[html]Public Function PutWindowOnTop(pFrm As Form)
Dim lngWindowPosition As Long LngWindowPosition = SetWindowPos(pFrm.hwnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE Or SWP_NOSIZE)[/html]

it says error.
im using vb 6...

I don't think that is C++

well it's for a crosshair...
this is my code for the buttons:
[html]Private Sub Command1_Click()
Call PutWindowOnTop(Form2)
Form2.Show
Call PutWindowOnTop(Form3)
Form3.Show
End Sub

Private Sub Command2_Click()
Call PutWindowOnTop(Form2)
Form2.Hide
Call PutWindowOnTop(Form3)
Form3.Hide
End Sub
