BUG in 2022? ApplicationEvents oAppEvents_OnReady doesnt fire

[Frederik_Mussler]

Hey guys,

i just upgraded from Inventor 2019 to Inventor 2022. I just noticed that in my addin an InventorEvent is not fired anymore. Does anyone have the same issue. Simple Expample when i start Inventor i expect the "Ready" Messagebox to show up, but nothing happens. If i close Inventor, the MessageBox "Close" appears. So is there a bug in the new version or what is wrong?

Public Class StandardAddInServer
Implements Inventor.ApplicationAddInServer

' Inventor application object.
Private m_inventorApplication As Inventor.Application
Private WithEvents oAppEvents As ApplicationEvents

Private Sub oAppEvents_OnReady(BeforeOrAfter As EventTimingEnum, Context As NameValueMap, ByRef HandlingCode As HandlingCodeEnum) Handles oAppEvents.OnReady
            MsgBox("READY")
End Sub

Private Sub oAppEvents_OnQuit(BeforeOrAfter As EventTimingEnum, Context As NameValueMap, ByRef HandlingCode As HandlingCodeEnum) Handles oAppEvents.OnQuit
            MsgBox("QUIT")
End Sub

Hello

Can't test with Inventor 2022 right now, but just for the sake of clarity, your Addin is sure loaded at  Inventor start? What type of load behaviour is in your .addin file?

Where is your oappevent declared?

Like :

Oappevent =inv.applicationevents

[bradeneuropeArthur]

Private m_inventorApplication As Inventor.Application Private WithEvents oAppEvents As ApplicationEvents
oAppEvents =m_inventorApplication.ApplicationEvents

Private m_inventorApplication As Inventor.Application
Private WithEvents oAppEvents As ApplicationEvents

Hello

Tested it now with 2022 and the event is fired.

[bradeneuropeArthur]

Please upload the complete code to see where the declarations are.

I am missing things!

[Frederik_Mussler]

Sry, my posted code was not complete. Since i'm talking about a plugin that worked perfectly in 2019, i have not changed a line of code. So just for testing i startet a new blank addin with the SDK Template for Visual Studio.

Namespace InventorAddIn1
    <ProgIdAttribute("InventorAddIn1.StandardAddInServer"), _
    GuidAttribute("79167e06-f668-480d-8f20-ddb230a4da37")> _
    Public Class StandardAddInServer
        Implements Inventor.ApplicationAddInServer
        Private WithEvents m_InEv As ApplicationEvents
        Private WithEvents m_uiEvents As UserInterfaceEvents
        'Private WithEvents m_sampleButton As ButtonDefinition

#Region "ApplicationAddInServer Members"

        ' This method is called by Inventor when it loads the AddIn. The AddInSiteObject provides access  
        ' to the Inventor Application object. The FirstTime flag indicates if the AddIn is loaded for
        ' the first time. However, with the introduction of the ribbon this argument is always true.
        Public Sub Activate(ByVal addInSiteObject As Inventor.ApplicationAddInSite, ByVal firstTime As Boolean) Implements Inventor.ApplicationAddInServer.Activate
            ' Initialize AddIn members.
            g_inventorApplication = addInSiteObject.Application

            ' Connect to the user-interface events to handle a ribbon reset.
            m_uiEvents = g_inventorApplication.UserInterfaceManager.UserInterfaceEvents
            m_InEv = g_inventorApplication.ApplicationEvents

            ' Add to the user interface, if it's the first time.
            If firstTime Then
                AddToUserInterface()
            End If
        End Sub

        Private Sub m_InEv_OnReady(BeforeOrAfter As EventTimingEnum, Context As NameValueMap, ByRef HandlingCode As HandlingCodeEnum) Handles m_InEv.OnReady
            MsgBox("INVENTOR READY EVENT")
        End Sub

        Private Sub m_InEv_OnQuit(BeforeOrAfter As EventTimingEnum, Context As NameValueMap, ByRef HandlingCode As HandlingCodeEnum) Handles m_InEv.OnQuit
            MsgBox("INVENTOR QUIT EVENT")
        End Sub

Quit Event Works, Ready not.

Hi,

Are there other addins that use the ApplicationEvents?

What happens if you unload all Add-ins also from starting automatic.

and start Inventor new with only your add in loaded.

does it work than?

[Frederik_Mussler]

Hi, 

good idea, i started inventor with all addins unloaded except my addin, and so the Event was fired. So yes indeed it works than.

So enabling back the build in addins from inventor i just came across the Autodesk.Feedback.Inventor.addin

If i disable this addin everything works fine, if the feedback addin is enabled, i have the problem again with the event not getting fired.

Inventor Product Feedback Add In | Search | Autodesk Knowledge Network

So due to it is not an important addin, i can just let it disabled, maybe others can reproduce this behaviour and we can add this as a bug?

[bradeneuropeArthur]

So partly solved!

Could you please take a look at this with the development team?

[Frederik_Mussler]

Yes thank you 🙂

Some news:

The issue of not working event ApplicationEvents.OnReady due loaded Feedback Add-On appears again in Inventor 2025 (2025.2 of October 2024)

I opened a support ticket - Confirmed, it is a bug (related to outdated NLog version 4.0). Autodesk will fix in future version.
