Displays a basic analog clock on a form.
CREDIT FOR THE ORIGINAL CODE GOES TO: Boriza
I enjoyed his code so much I had to add a couple
of quick improvements. Incrementally uncomment
the code lines in the Form_Load event for
different clock positions on the form.
Assumes
Just add a timer("timer1") to a form and
paste this code into the form.
VBcodersOption Explicit
Private Const Offset = 50 ' Border offset
Private cX As Single, cY As Single ' Center Point
Private r As Integer ' Radius
Private Sub Form_DblClick()
' Allow form double-click to unload clock
Unload Me
End Sub
Private Sub Form_Load()
' Remove redraw flicker
Me.AutoRedraw = True
Timer1.Interval = 500
' Clock size (radius)
r = 500
' You can center clock on the form...
cX = Me.Width / 2 - Offset
cY = Me.Height / 2 - Offset * 2
' OR you can put clock top-left on form...
' UNCOMMENT TO SEE
' cX = r + Offset * 2
' cY = r + Offset * 2
' OR even a kind of combination - REMOVE THE FORM's CAPTION AND
' CONTROL BOX FOR FULL EFFECT.
' UNCOMMENT TO SEE
' Me.Width = r * 2.5
' Me.Height = r * 2.5
' cX = Me.Width / 2 - Offset / 2
' cY = Me.Height / 2 - Offset / 2
