Strong name

Anonymous — Fri, 22 Jul 2005 20:18:52 GMT

I am a beginner to VB, so this may be a dumb question. I have no strong name
selection. I am trying to be able to run this from autolisp.

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndotnet/html/callcomcomp.asp
under "Create a Key Pair and Sign the Assembly" Step # 3. I have no Strong
name property page.
how do I get one? Is there another way?

What are you trying to call from LISP and why are you trying to put a COM wrapper around a .NET solution?

I am working with a pre net enabled release of AutoCAD. I am good with lisp,
just trying to make the transition slowly. or see how the two can work
together? I suppose I could purchase a downgrade to a previous version of
VB. I thought it would be easier to focus on the .net version rather than
try to figure out how to do it the old way as well.

You can just compile your .NET app and call a shell. You don't need to convert it to a COM app to use it.

if you could also read the above post vla-object with no properties or
methods. Compiling that same class library would work if I used it from
VBA. It will not work from lisp.

How do I call a shell?

Thanks.

If you actaully want to access a .NET class then yes you will have to put a COM wrapper around it which does need a Strongly typed key

I'm just working through that file I posted from the msdn help file. that is
about all I know about the subject. I have been working with .net since
june. is there something else I can do? I can try to do it withoout the
other functions from the bat file.

thanks.

To strongly name your assembly see http://andrewconnell.com/blog/archive/2004/12/15/772.aspx

You can wrap com around dotnet and use it from lisp, it works just fine. It beats the heck out of using DCL or VBA for forms.

I used it from lisp to kick a splash screen and get the CLR up and running.

Here is some VB.net code created as a new class and called AmerXSplashScreen. I have blanked out the GUID's so they don't conflict with my com object, so you will have to generate your own in the dotnet UI. Be sure you have "Register for COM Interop" checked on the build tab.

You can strongly name the assembly and install it to the GAC so Autocad can find it, or you can copy the assembly to the Autocad Program directory (good for quick development).

Option Explicit On

You can't release the dll from memory as netload has loaded the assembly into Autocad's domain.

You supposedly can load an assembly into your own domain so it can be unloaded, but I have never had a use for that.

I just make sure to call dispose on the object so it can release resources when I am done with it.
