I tried doing this a few years ago. I don't think that much has changed since then unless you are using .net. IMHO packages are a better solution as you can pass objects between modules. Doing this with dll's is rather difficult, but you could probably get around it by using interfaces. There are several free and commercial toolkits. Remobjects.com have hydra, tmssoftware.com has one, and there is a free framework in the jvcl. All of these will allow loading of packages at runtime etc. Regards Sean ----------------------------- Sean Cross Systems Development CRM PO Box 230 Napier Phone: 06 835 5868 Mobile: 027 276 6439 Email: [EMAIL PROTECTED] Disclaimer: "The information contained in this document is confidential to the addressee(s) and may be legally privileged.
