Michel,

I've never used the SEPARATOR, but I find the CONTAINER handy for three uses. First, it can be used to group a number of objects together that are placed "inside" the container. The objects can then be moved and positioned as a group. Secondly, CONTAINERs allow special visual effects for objects by selecting "raised" or "sunken" as the layout SpecialEffect. Some objects like radio buttons are designed by FoxPro to be in containers of their own because radio buttons are always logically associated with each other. Thirdly, I've used containers to put little pictures on a form that can change when data or conditions change. This is done by changing the container's "picture" property. For example, a locked or unlocked padlock picture to indicate the locked status of a record. The container makes a nice little frame around the picture. You change the picture programmatically by:

thisform.container1.picture="whatever"

Remember, when using containers you must include the container name to identify the objects inside, for example:

thisform.container1.command1.enabled=.f.


HTH!
Allen
