Sorry, it's only for little shapes (for example: height=width=100)

Now i found in MSDN:
99 - Specifies maximum curvature and creates a circle or ellipse.

And from MSDN too:
frmMyForm = CREATEOBJECT('Form') && Create a Form
frmMyForm.Closable = .F. && Disable the Control menu box

frmMyForm.AddObject('cmdCommand1','cmdMyCmndBtn') && Add Command button
frmMyForm.AddObject('opgOptionGroup1','opgMyOptGrp') && Add Option Group
frmMyForm.AddObject('shpCircle1','shpMyCircle') && Add Circle Shape
frmMyForm.AddObject('shpEllipse1','shpMyEllipse') && Add Ellipse Shape
frmMyForm.AddObject('shpSquare','shpMySquare') && Add Box Shape

frmMyForm.cmdCommand1.Visible =.T. && "Quit" Command button visible

frmMyForm.opgOptionGroup1.Buttons(1).Caption = &quot;\<Circle&quot;
frmMyForm.opgOptionGroup1.Buttons(2).Caption = &quot;\<Ellipse&quot;

frmMyForm.opgOptionGroup1.SetAll(&quot;Width&quot;, 100) && Set Option group width
frmMyForm.opgOptionGroup1.Visible = .T. && Option Group visible
