When you apply the CommandMethod attribute to a non-static method, AutoCAD's
managed runtime will create multiple instances of your class, one for each
document that you invoke the command in. Those instances are not created until
you invoke the command.
The problem you have is that AutoCAD's managed runtime also creates an instance
of the class with the IExtensionApplication attribute on it as well, so multiple
instances of your class are getting created, which obviously wasn't your
intention.
For one thing, it's not wise to implement commands in the same class that
implements IExtensionApplication, but if you really wanted to do that, you could
if you make the command handler methods static. If you're not sure about the
difference between static and non-static (or 'instance') methods, get a hold of
some basic C# learning materials, and try to become more familar with the basic
concepts that underly the tools you're working with.
To solve your immediate probelm, just create another class for the commands, and
unless you want AutoCAD to create multiple, per-document instances of the class,
declare the methods that have the CommandMethod attribute as static methods.

Hi,
Can anybody explain the strange behavior of this peace of code.
This .dll is registered in order to load on startup.
{code}
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\Software\Autodesk\AutoCAD\R17.1\ACAD-6001:409\Applications\TestCAD2]
"DESCRIPTION"="Ognyans test app"
"LOADCTRLS"=dword:00000002
"MANAGED"=dword:00000001
"LOADER"="C:\\work\\LocalTestProjects\\acad_CUI\\acad_CUI\\bin\\Debug\\acad_CUI.dll"
{code}
1. When I comment out the "initialize" method the module is starting but the
class constructor (Class1) is not starting until I invoke "c1" or "c2".
2. When I don`t comment out anything the program "brakes" in the initialize
method in the line
doc.SendStringToExecute("_.cuiload " + cuiFile + " ", false, false, false); but
Autocad continues to work without error prompt, but no CUI is loaded.
3. After deleting the registry info and when I netload the .dll without
commenting out any code the initialize method the .dll is loaded and the cui is
loaded - everything is fine.
c1 command is working fine when netload-ed by hand.
Why is that? To me it looks like that Acad cant receive the command for loading
the cui before it loads some other stuff after.
If you place a message in the initialize method the message will appear before
the last Acad default console messages.
Is there a way to tell the initialize method to wait until Acad is ready to
receive?
