[I don't code much in VB]

I have a DLL written in VB, displays nothing when it runs. I want to change it to display a form with information that is updated as the DLL proceeds, in some cases, the DLL might be running for some time, and I need to know if it hung waiting for external events, or whether is is still actively processing data.

I also need a way for the user to press a button to get it to stop activity and terminate gracefully.

When I do a show form, I get

Non-modal forms cannot be displayed in this host application from an ActiveX DLL, ActiveX Control, or Property Page...

I can do a show vbModal but then it just sits and wait till the form is closed.
