Collection objects with C/SIDE

Hi all, I’m programming an interface from Attain 3.60 to another application via COM (automation server). Some of the objects are returning collection objects and Navision seems not to be able to handle them. I’ve tried to put the returned collection into a variant and format them to text, so I can see the members of the collection, but Navision crashes. Is there any workaround? May be a OCX the solution, that receives the collection an returns the members formatted as text to Navision? Anyone done this? I’ve not so much experience writing OCXs. Thanks Alex
