Hi Jimi,

Yeah, you want to use a TabStrip control. It's kind of hokey, I recommend the one from Sheridan Software.

>(2) How can I add objects into a frame? Just like using container in VFP?

Yup. Just make sure you have the tab highlighted when you place the control on it. Note than when referencing contained objects, there's no object calling hierarchy as in VFP, ie; no THIS.Parent.txtName.Value - you can just use txtName.Value from anywhere. VB enforces unique names for every object on a form.

>(3) Is it possible and how can I know what functions are available in an OCX? I'm studying a new device and dunno how to use the API come along with it :(

Yes, intellisense should pick these up for you in code. In a sub for the form that contains the control, just type the control name and then "." and wait. A popup menu with all of the available PEMs will be available.

HTH,
