Tracy,

Tried that... no joy.

My code is a little misleading as I meant to say:

Slight mis-information in the last post in that:

"Unknown OCOLLECTION_X - Undefined The collection is mainly used in the "myRefresh" event of the component

(base class is a container) and is initialised to null on the property sheet, subsequently getting populated in the actual <<container>>.Control_Source_Assign method"

Should be read as " .... <<container>>.oCollection_Assign method".

I use a user defined property Control_Source to bind the collection to the object in a similar way to the native ControlSource property.

This is now baffling me completely.

basically parsed through element by element refreshing a discrete control for every instance in the collection.

time and I have tried all types of External commands thinking that the oCollection not being found could be fixed as you do with external arrays.

However there isn't an "External Collection" command... so I am now stuck!

Dave,

Backup, then pack the VCX. Sounds like you have a lost/corrupt code bit.
