i developed a small dll in vc++ using objects with the default vc++ dll
template

how can i instance the object in the dll from my vb project

thanks

alexhguerra,

In a VB project, from the 'Project' menu choose the 'References...' command.
Browse for your Dll using the browse button.  Add it to the list and make
sure it is ticked.  Your dll is now added to your VB project.  To
instantiate it ...

Private mobjMyDLL As MyDLL.ObjectWithInTheDLL

'==========================================================
Private Sub Class_Initialize()

    set mobjMyDLL = New MyDLL.ObjectWithInTheDLL
End Sub
'==========================================================
.
.
'==========================================================
Private Sub Class_Terminate()

    set mobjMyDLL = Nothing
End Sub
'==========================================================

You have two options:
- Export global methods that act on objects that are internal to the
  DLL.  The global methods should be declared as __stdcall.  If you
  set it up right, you might be able to pass "handles" to internal
  objects out to VB, where they are pointers on the C++ side and longs
  on the VB side.  This would require use of type-casting on the C++
  side and consequently you'd lose type safety when they get passed
  back to C++ from VB (i.e. if you{*filter*}it up, it's very likely to
  GPF on you rather than failing gracefully).

- Export COM objects from the DLL.  This is NOT trivial.  It's probably
  easiest to do it using the ATL and associated wizards.  I've never
  done it myself, so I shan't offer any advice.
