    Talking

    I found a new API named AnimateWindow.
    You can declare it like that:

    Private Declare Function AnimateWindow Lib "user32" (ByVal hwnd As Long, ByVal dwTime As Long, ByVal dwFlags As Long) As Long

    And codes here:


    Private Sub Form_Load()
    AnimateWindow hwnd, 200, 16
    'dwFlags can have value as 1,2,3....
    End Sub

    NOTE: 1.Form1.BorderStyle should not be "0-none"
    2.Win2000 is necessary.

    Question

    I recently installed Win2k. The most part of my VB API calls doesn't work any more.

    Can you adress me to any site with info about API & Win2k?

    Thanks in advance, Roby.

    Private Const WS_EX_LAYERED = &H80000
    Private Const GWL_EXSTYLE = (-20)
    Private Const LWA_ALPHA = &H2
