installing a NET interCOM dll

Anonymous — Sat, 17 Sep 2005 13:56:51 GMT

i have developped an acad application, it has some dll's called from a vba macro of autocad, i have no problems to call the vb6 dlls, but im having lot of problems to call a net dll

if i compile the net dll with VS2003 and chek 'register for com interoperability' there is no problem
i can call the dll from the autocad vba macro on this way

Set VB6DLLG = ThisDrawing.Application.GetInterfaceObject("ClassLibraryG.ComClassG")
VB6DLLG.Main

VS2003 register the assembly as private, and it appears on C:\WINDOWS\assembly\download as private, with no key or strongname

but now i want to test the installer, so i unchek 'register for com interoperability' on VS2003 and compile
then i run %windir%\Microsoft.NET\Framework\v1.1.4322\regasm.exe /codebase /tlb "C:\Program Files\programa\ClassLibraryG.dll"
and create the tlb library for COM, but then i cant call the classes, it gimme error -2147024894 (80070002) in the autocad vba macro
the error is the same if i add a reference to tlb library in the VBA IDE of autocad

the vba, dll and tlb are on the same directory C:\Program Files\programa\

so i really dont know where is the problem, anybody knows?
thanks in advance

While
implementing ClassInterfaceType.AutoDual be aware of the
following:

-

(ClassInterfaceType.AutoDual vs.
ClassInterfaceType.AutoDispatch)

ok, im reading this about the question, still learning NET

there are some pretty details, for example, i can use a unique dll for all acad 16 versions (2004,2005 and 2006)
NET loads Autodesk.AutoCAD.Interop.dll and Autodesk.AutoCAD.Interop.Common.dll
from the instalation folder and use them in all versions
thats great
