AutoCAD Inventor :: How To Prevent DLL Addin From Reverse-engineering
Sep 24, 2012
We create a greate deal of DLL add ins for Inventor using Microsoft VB.NET. The code security is very important to us. I hear certain program such " Lutz Roeder's Reflector " can reverse engineer the DLL assemblies and get the actual code from it. This would cause concern when we deploy the DLL to various users.
So, is it true that DLL from VB.NET (or C# and C++) is so vulnerable from reverse engineering? if yes, what is any practice to add security to it?
I have a problem with aligning the model. At the beginning I could not see drawings in correct position after putting them from assembly window to drawing one( please see the screenshot). I solved it in the drawing mode( I set them straight so I can do engineering drawings), but I am wondering if there is a possibility to set any object in assembly mode horizontally vertically so in the drawing mode it will not show incorrectly after adding them. Also I made a drawing file for Auto Cad mechanical and parts are also set tilted.
In the engineering notebook, I have sectioned the assembly so that I can show what I need to note. I would like to freeze the view. When I freeze the view, the section goes away and I cant see what I need to.
Working in a assembly and just edited an existing note in the Engineering notebook. Clicked the "X" to close the assembly.... what? no prompt to save the file?
Just checked adding a note to a ipt and it doesn't dirty the file either, so if you only add a new engineering note, you have to save it, cause it won't prompt you before closing.
In my part, there was already an existing Engineering note.
I wanted to add another note. I added my new note, but it does not show up in the browser. I can right click on the note note > Display note and both notes are shown in the engineering notebook. When I exit out of the notebook and go back to Inventor, still not there. Here is a short video of what I am seeing.
[URL]. The "Rev B" noteis the original one and Note 2 is the one that I just added.
Now I if I add another note, then all of them will show up in the browser. This is not the first time that I have seen this, but just thought I would bring this up.
This part was just made with a copy design from Vault. What is weird, is that if I go to the part that this was copied from and add the note, it shows up correctly then. Its like something is getting hosed in the copy design process.
Below is a link to a github repo that has a code example showing how to embed an IronPython engine inside a C# addin. It is the same as the "Simple AddIn" that comes with the SDK, only with the logic part of the addin factored out into IronPython. I could never find anything on using IronPython with Inventor so I'm posting this for any others that might be interested.
The main reason for doing this is to speed up development time. Edits related to the python code do not require the cycle of shutting down Inventor, compiling, restarting etc. More detail is in the readme. URL....
I followed exactly step-by-step showing in the program. After compile the DLL register the registry, run IV, I couldn't see the AddIn SampleToolbar in the Panel bar.
I would like to make an Inventor AddIn with commands (functions) that can be called from other standalone applications. I have tried to create a COM interface for my AddIn, and that works with rather small effort, but I think I have heard that it should be possible to do this without the COM interface. I would like to avoid COM if possible. if I need to do anything special in the AddIn to make the function visible and how I on client side calls the function.
I have an addin which displays a form, then when I click a button operations are launched. The form is no modal, so I display it, select objects, apply, select objects, apply,... then close the form with another button (form.close).
All functions, but only on the first opened file : I open the file, use the addin, close the form. I open another file, the addin is always loaded, but when I click on the icon to display the form nothing happens... I have to unload the addin and reload it.

I have an Addin with several pieces of functionality that I have been working on for over a year now and have had no problems with it loading. Yesterday I was working on a bug in a function and when I set a break point it was not breaking in the correct location. Possably some miss match between the source and .pdb files. I tried a clean build but still could not get the break point to be correctly aligned with my source code.
I tried to unregister and re-register the Addin with regasm but no luck. I then decided to search the registry for the name of my Addin and was supprized to find thousnads of registry entries. I then decided to clean my registry of all occurances of the Addin name. After removing all occurances of my Addin from the registry my Addin would not load.
I tried putting a message box in the first line of the Activate sub but it never executes. I made the assumption that it was a problem with the registry and changed the GUID value. When I did a rebuild I got the following error:
Error 1 The "UnregisterAssembly" task failed unexpectedly. System.Runtime.InteropServices.COMException (0x80030002): could not be found. (Exception from HRESULT: 0x80030002 (STG_E_FILENOTFOUND)) at Microsoft.Build.Tasks.NativeMethods.UnregisterTypeLib(Guid& guid, Int16 wMajorVerNum, Int16 wMinorVerNum, Int32 lcid, SYSKIND syskind) at Microsoft.Build.Tasks.UnregisterAssembly.Unregister(String assemblyPath, String typeLibPath) at Microsoft.Build.Tasks.UnregisterAssembly.Execute() at Microsoft.Build.Framework.ITask.Execute() at Microsoft.Build.BackEnd.TaskExecutionHost.Microsoft.Build.BackEnd.ITaskExecutionHost.Execute() at Microsoft.Build.BackEnd.TaskBuilder.ExecuteInstantiatedTask(ITaskExecutionHost taskExecutionHost, TaskLoggingContext taskLoggingContext, TaskHost taskHost, ItemBucket bucket, TaskExecutionMode howToExecuteTask, Boolean& taskResult) AnthroAddIn
I ran the build again and did not get the error.This Addin is loaded on every CAD workstation in the company using an install program written with the Inno Setup Compiler. I installed the Addin using the installer and the Addin still will not load on my machine.
What is the best approch to debugging an Addin that will not load?When is it necessary to re-register your Addin using regasm?Is it possable that this problem is being caused a problem with the registry?I have read a number of posts regarding problems with Addin's not loading but have not found anything simmilar to this.
I've used vb.net to write two separate addins. I was wondering if there is a way to pass a variable from one addin to another similar to the way shared variables are passed from rule to rule in iLogic.
I have having difficulty getting any addins to load at the moment and am totally stumped as to what the problem is. I have even created a very simple addin from the (C#) template, compiled and registered it and it still will not load up. I get the addin to appear in the Inventor Add-ins dialog ok but it will not load for some reason. I have tried generating various .Net versions 2.0, 3.0 & 3.5 all produce the same result. I have also tried to debug the add-in by getting Visual Studio to launch Inventor but it does not even appear to be loading the add-in. I have dug out some work I did months ago and tried that but it does not work either. Is there a log in Inventor?
I am using C# in Visual Studio 2008 Pro & Inventor 2011.
show me an event handler (or whatever is needed) for bailing out of an AddIn? I'm using VB.net. The end users would prefer to use the ESCAPE key for this.
Using Inventor 2014 and Vault Basic 2014. It was working this morning but now when Invnetor is opened it automatically logs into Vault and says it is successful but the open from vault icon is greyed out. Similarly when opening a drawing from the vault it used to automatically run and open inventor but now seems to lack the connection. Even when manually opening a drawing that is in the vault by downloading it from the browser and then opening in inventor there is no Vault tab on the browser and all Vault commands except "log out" are greyed out. I think it has something to do with the add-in as well as the Vault group.
I have an issue where an addin loads once the first time Inventor is opened. If the addin is unloaded and reloaded via the Addins dialog and no documents are open it loads once. If the addin is reloaded while a file is open is reloads twice.
I came to the conclusion it is loading multiple times because the it seems to go through the Activation method of the addin twice. When is the Activation method called during loading an addin?

Is it possible to use the DXF Translator Addin to export a sketch?
I've managed to export a sketch using the DataIO mechanism, but I need to be able to export the DXF in an older file version than 2010. Is there any way to specifiy the version to export to using the DataIO mechanism?
I'd like to make it so that a user may add a button for my addin by only having to modify an xml entry.
None of the values (name, descrip, tooltip) are null, and reading from the xml is working properly. Each internal name is unique. Why this code would result in an error? The error message is attached.
If there's a known way to dynamically add buttons(in a loop), I'd be happy to use an established method as well.
I have been trying to convert a working(mostly) addin to dockablewindow. I found one (and only one) sample in c# (wich is what i am using). I finnally got it to show up as a dockable window but when the user presses the "X" on the window it hides, how do you get it back or just let the addin know that the window/form has been closed so that when the user pressed the ribbon button that spawned it can just show it or create a new one?
I have found vary lilttle on dockable windows on Google, Bing...
Have a problem of users using files in their local workspace instead of getting the latest files from Vault?
This is an Inventor question because my next step will be to develop an Inventor addin which deletes files from a user's local workspace when they check the files in.
I would like to create an addin in VS2010 & IN2012. How I could able to do this? I have started with "simpleAddin". But, while building I could able to see the following error.
The same error for all Addins.
Error 1 The command "mt.exe -manifest "E:Program FilesAutodeskInventor 2012SDKDeveloperToolsSamplesVB.NETAddInsSimpleAddInMy ProjectSimpleAddIn.manifest" -outputresource:"E:Program FilesAutodeskInventor 2012SDKDeveloperToolsSamplesVB.NETAddInsSimpleAddIninSimpleAddIn.dll";#2 " exited with code 9009. SimpleAddIn
I have an addin which has an icon for a button. In Inventor 2012 it displays fine. In Inventor 2013 the icon appears to be enlarged by about 4x, and only the top left corner of the icon is visible. The api clearly states that Inventor will scale the image to size.
This is the C# code I'm using to load the icon. The icon is in my resources file.
