>I've not seen any controls that use arrays as ActiveX properties, but I've not had a lot of exposure to a lot of different controls. They're usually not arrays, they're structures. There are a couple of files here that help with that sort of thing. There's STRUCT.ZIP File# 346 and CLSHEAP.ZIP File#94826.

Not that it will help in this discussion because I haven't found a work around for it, but an example of this can be found using the ADSI ActiveX control.

There is a Filter property that accepts an array. You can use this property to filter out items of a particluar type when looping through the members collection of any ADSI container object.
