This VB application main window has higher priority than others. Even you
focus on other opened windows, this VB application is still on the top and
keep running. I have seen some windows applications like this, I would like
to know if this can be done in VB, and how?

To force the form to say on top, try the following code:

Option Explicit
Private Declare Function SetWindowPos Lib "user32" (ByVal hwnd As Long, _
ByVal hWndInsertAfter As Long, ByVal x As Long, ByVal y As Long, ByVal cx As
_
Long, ByVal cy As Long, ByVal wFlags As Long) As Long

Private Const HWND_TOPMOST = -1
Private Const HWND_NOTOPMOST = -2
Private Const SWP_NOMOVE = &H2
Private Const SWP_NOSIZE = &H1

Private Sub Form_Activate()
  Dim lRet&

    lRet& = SetWindowPos(Me.hwnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE Or
SWP_NOSIZE)
End Sub

To stop it being on top, send a SetWindowPos with an argument of
HWND_NOTOPMOST.
