number pixel

How can I determine number pixel in resolution?

Try to use Screen.Width and Screen.TwipsPerPixelX
You'll get needed values.

If x > 800 And y > 600 Or x < 800 And y < 600 Then
    MsgBox "This Program Is Designed In 600 By 800 Mode, " _
    & "Please Reset Your Resolution Settings To Get The Best Effect"
    End
End If

bp = GetDeviceCaps(Me.hdc, BITSPIXEL) 'get the bits per pixel
MsgBox "Current Resolution Has " & bp & " Bits / Pixels"

ncol = 1

For i = 1 To bp 'determine number of colours
    ncol = ncol * 2
Next

MsgBox "Number Of Colors Is " & ncol

End Sub
