Hi A1880 I am aware of the thread on serial comms the question wasn't specific to that. In VB many things are controls which are referenced in the project which adds them to the tool bar other things are API's which are referenced in code then called. It appears to me that most things for Jabaco are Java API's which must be referenced in code not controls, is this a fair statement? Mike

Hi A1880 thanks for the reply, I'm trying to understand how Jabaco hangs together. I have an application written in VB5 which incorporates 3 serial comms controls. Ive done a little research on comms API's for Java but I'm not sure how to invoke them within the Jabaco environment. Mike

Hi All this may be a dumb question but how do you add a control to the tools toolbar within the IDE thanks Michael Bennett
