Commands not registering

[rollinson44]

I have been using my applicaiton as I develop it and have had no problem until today. Suddenly my commands are no longer registered in Autocad and no matter what I try I can't get them registered again. The problem began when I added a commandmethod in another class in the project and inlucded the assembly reference to that class. I have since removed that method to the main class and removed the assembly reference; however, I can't get it to work now. I am including the entry class code, if someone might have some insight into this that would be great. This is driving me crazy. I am running Autocad 2008. The debug info under project properties is set to the correct .exe and path. I have the correct references and have tried to remove and reload them with no luck.

That fact that your command was working and you have code in the interface-implemeting method Initialize() prompts me that the most possible reason is your code runs into exception in the Initialize() method.

In most case exception that occurs in Initialize() would not kill AutoCAD, it "kills" the loading DLL that causes the Initialize() without saying anything.

I always place try...catch to box all code I have to write in Initialize(), even I do nothig in the catch... part:

public void Initialize()
{
try
{
//your code here
}
catch{}
}


By the way, I saw your commands below which show forms in Acad. According to Acad doucment, you do not use System.Windows.Forms.Form.Show()/ShowDialog() to show win form in Acad, use Autodesk.AutoCAD.ApplicatioonServices.Application.ShowModelessDialog()/ShowModalDialog() instead.

If you use the CommandClass attribute on a class that has command methods,
you must use it on every class that has command methods.

From your description of when the problem started, that seems to be the
problem.

This is very useful for me, also an artical on http://tson.com/net-autocad-commands-regist/
