Reza,

In your lowest level Label class you might want to put AutoSize = .t. and BackStyle = 0 and then all of your labels derived from the class will size according to the Caption and let the background show through.

>I make my forms and app in vfp7 and windows98.but when i run my app in windows xp,
>the color of my object (such as OPAQUE LABEL ) chaged .
>my form area color is not same as background label color.
