Marc,

I develop in VFP 5 so this may not work in VFP 3.0 b.

Container type objects have an array - 'Controls()' which can be accessed like this:

LOCAL loObject, liIdx

loObject = thisform
FOR liIdx = 1 to loObject.ControlCount STEP 1
     loObject.Controls(liIdx).myMethod()
     loObject.Controls(liIdx).myProperty = SomeValue
ENDFOR

Of course 'myMethod' and 'myProperty' must be defined in the control being accessed. You can use PEMSTATUS() to check for the existence of the method/property (not sure though if this function is available in 3.0 b??).

Also, you may need to drill down into any container objects that are members of the container currently being processed. If you have a pageframe that needs to be processed, use the 'pages()' array in a similar fashion.

Hope this helps.
