AutoCAD Adding ribbon tab on startup

[CaveMan]

Good Day

Often when developing a .net application for AutoCAD one can add the "netload" command in the acaddoc.lsp file, and enable load acad.lsp with every drawing.

However at times this does not function, as in Plant 3D, as there are other commands uploading, if a command is run like this it crashes AutoCAD?

(vmon)
;------------
(command "netload" "C:\\VB.Net\\Development\\Plant3DHelpDesk\\bin\\Debug\\Plant3DHelpDesk.dll")
(command "hd")

Is there an alternative method of automatically loading a .Dll application into AutoCAD on startup?

Any assistance much appreciated.
Have an Idea it may have something to do with creating an .arx file??

I stumbled upon this thread while looking for something else, and thought I'd answer your question whilst here....

To load the .NET assembly at startup, you should use a Registry Loader for pre-2012 versions, as 2012 and newer support the Autoloader mechanism.

Now, the registry loader will simply load your code (make CommandMethods and LispFunctions available, etc.), in order to invoke a method at load, we use the IExtensonApplication.Initialize() Method with an ExtensionApplication Attribute call prior to one's Namespace. This blog post should help.

ObjectARX has nothing to do with the loading of .NET assemblies.
