The code lets you implement Analog Clocks and Meters like the Windows clock setting arrangement.
VBcoders
Mmin As Double, Mmax As Double, Handw As Integer, Color As String, Handl As Double, _
Value As Double)
' The meter is assigned to a picture array (using Picture1).
' The Picture1 attributes are important. Set Scalemode = Pixel (3)
' Autosize = true
' Autoredraw = true
' Font Transparent = true
'
' Index = Which Meter to Adjust
' Mtype = Which Type of Meter it is (1=center dial, 2=half dial)
' EMin = Engineering Units Zero (Minimum)
' EMax = Engineering Units Span (Range)
' MMin = Minimum point on the meter face (0-60)
' MMax = Maximum point on the meter face (0-60)
' Handw = Thickness of dial hand (1,2,3)
' Color = Color of dial hand (vbRed, vbBlack)
' Handl = Length of the dial hand (0.1 is a good length)
' Value = The value to set the dial
If Mtype = 1 Then
Mdeg = 0 ' degrees (0-360)
cx = Picture1(Index).Width / 2
cy = Picture1(Index).Height / 2

If Mtype = 2 Then
Mdeg = 270 ' degrees (0-360)
cx = Picture1(Index).Width / 2

r = IIf(cx > cy, cy, cx) - 5
sl = r * Handl 'length of meter hand
r1 = Emax - Emin
r2 = Mmax - Mmin
s = ((r2 / r1) * Value) + Mmin
sin_ = Sin((Mdeg - s * 6) * Deg2Rad) * (r - sl) + cx
