为什么小弟我做的ActiveX控件的Font属性无法在属性窗口显示出来

为什么我做的ActiveX控件的Font属性无法在属性窗口显示出来？
我做的控件由一个lable(名称为lblCaption)与一个timer组成,我用以下代码设置了控件的font属性:
Private   mfonFont   As   StdFont

Public   Property   Get   Font()   As   StdFont
'the   value   for   the   control 's   font   property   is   "stored "   in   the   lblcaption   object 's   font   property
Set   Font   =   lblCaption.Font
End   Property

Public   Property   Set   Font(ByVal   NewValue   As   Variant)
'store   the   control 's   new   font   value   in   the   lblcaption   object 's   font   property
Set   lblCaption.Font   =   NewValue
UserControl.PropertyChanged   "Font "
End   Property

Private   Sub   UserControl_WriteProperties(PropBag   As   PropertyBag)
PropBag.WriteProperty   "Font ",   Font,   mfonFont
End   Sub

Private   Sub   UserControl_ReadProperties(PropBag   As   PropertyBag)
Set   Font   =   PropBag.ReadProperty( "Font ",   mfonFont)
End   Sub

但是Font属性无法在属性窗口显示出来,请问是什么原因?

[解决办法]
第一行代码改为这样,加NEW关键字
Private mfonFont As NEW StdFont
