Hi: I have created a very simple user defined control (a container) with the visual IDE of Visual Foxpro 9 and stored it into a VCX file (sisweb.vcx)

After that I've created (visually) a form and in the INIT event I've tried to instantiate the previous container control and add to the form:

oContainer=newobject("xContainer","sisweb.vcx") ThisForm.AddObject("Contx","oContainer") ThisForm.Contx.Width=230

Unfortunatelly, when trying to ADD the container object, it rises an error saying that oContainer doesn't exists.

Can you help me please?

When you want to add an object dynamically at run-time, you could do something like

Thisform.NewObject("Contx", "xContainer", "sisweb.vcx") Thisform.Contx.Width = 230 Thisform.Contx.Visible = .T.

Where assigning the Visible property explicitly is important.

On the other hand, you could also add it "visually" in the Designer by dragging it from the Project Manager's "Classes" tab, or by using the bookshelf icon of the Form / Class Designer's "Controls" toolbar, or the "Toolbox" in the "Tools" menu

• 1 It may be worth stating what Alberto did wrong -- specifically, that VFP does not allow an existing instance to be added to a container. (In fact, I'm not sure very many UI designers allow that, due to the potential headaches.) – DougM Commented Mar 16, 2015 at 16:14
