An easy one, Im sure...

How can I stop screen refreshing and start it again? Anyone???

I wrote a chess prog, and to check for checkmate/stalemate, it makes every legal move for the opponent until they aren't in check (or it declares game over).

Problem is, the screen is flashy while pieces rapidly move around screen. I want to turn this off while checking the position (which should also speed up processing), then turn on again when done.

I am using images for the pieces. Any helpful ideas would be GREATLY appreciated.

Could you maybe set the properties of the pieces to invisible?

Try the LockWindowUpdate() API, it prevents Drawing Operations in a Specified Window, ie.

Private Declare Function LockWindowUpdate Lib "user32" Alias "LockWindowUpdate" (ByVal hwndLock As Long) As Long

Private Sub Command1_Click()
    'Stop Updating while performing the following operations
    Call LockWindowUpdate(Hwnd)
    'Put your Code here..
    'ReEnable the Updating of this Window
    Call LockWindowUpdate(0)
End Sub

Thank you so much, Aaron!

You, too, Bob...except that if a piece is invisible, it is considered to be "off the board". In other words, if I make them invisible, I couldn't see if there was a checkmate or stalemate, because there would be no "valid" pieces to check.

Thanks again for your help, guys.
