>>Now, I set my left listbox anchor to 135, right to 45, buttons to 768 (as Tamar said) in my cntMover class. I placed several instances of this class into another container class and I add it programmatically to the page of the pageframe. My listboxes and buttons seem to not change sizes or positions at all. What should I do to make anchor work?

>Anchoring of controls is relative to the container they belongs to (Container, Page or Form). IOW, you have to setup Anchor property of contaner(s) accordingly.

I don't understand what should I do with the container's Anchor. If I set inner objects anchor properties, does it mean that my inner objects would be resized properly?

In other words, I have a simple container class with two listboxes, label and 4 buttons. I set listboxes and buttons anchor properties. I placed this container object on the page and changed its size. Why I do not see any changes in my listboxes and buttons?
