Run-time creation of controls

 Is it possible to create a control at run-time?
  Say I need to use ListBox control inside *class module* just for maintaining of the sorted list of items.

  If you are familiar with Delphi there this is really simple. You write just this
  someControl := TsomeControl.Create(nil);
where nil is the empty "owner" of someControl (which is normally Form).
After that you set all properties you need and that's it.

  If the answer is positive I will increase points for any
code example.

Unforunatly, some controls cannot be created at run time, the listbox being one of them.  There is a rather simple workaround though.  Create a form and set it's visible property to false so that it will never display.  Place any controls you need at run time on this form.  For example, I usually name the form frmObjects.  Then, in your class, you redefine your objects as being the objects on the hidden form.  For example...

Options Explicit

Dim VList as ListBox

Private Sub Class_Initialize()
   Set vList = frmObjects.Listbox1
   ...
End Sub

Now these controls can be handled as if you had just created them in the class.   Hope that helps.
