OnSave Event handling for multiple Add-Ins

[catot]

I'm having some issues with the Document OnSave Event when developing multiple Add-Ins.

At first I created an Add-In and implemented the OnSave event with success (Add-In_1).

But now, I'm developing a second Add-In to also implement the OnSave event in that as well (Add-In_2).

These are completely separate Add-Ins, but I've copied over for example the code handling the OnSave event.

When debugging Add-In_2 and stepping into the code as I save the document, I've discovered that this is happening:

1. Add-In_1 trigger its OnSave event with kBefore eventTiming.
2. Add-In_2 trigger its OnSave event with kBefore eventTiming.
3. Inventor displays the Save Dialouge, I press OK to continue. (so far so good)
4. Add-In_1 trigger its OnSave event with kBefore eventTiming again. (why?)
5. Add-In_2 trigger its OnSave event with kBefore eventTiming again. (why?)
6. Add-In_1 trigger its OnSave event with kAfter eventTiming.
7. Add-In_2 trigger its OnSave event with kAfter eventTiming.
8. Add-In_1 trigger its OnSave event with kAfter eventTiming again.
9. Add-In_2 trigger its OnSave event with kAfter eventTiming again.

So, I'm looking for some advice and best practice of how to handle this and avoid the duplicate events firing, I'm clearly doing something wrong. Any feedback is appreciated, thanks.

Hi,

Are you using DocumentEvents or ApplicationEvents "OnSave"?

I'm using ApplicationEvents. Maybe I should not?

Hi,

This should work:

Please check the following:

• There definitely is a module or code that uses a document.save method when the file is saved.
  Try to find this piece.

After this we need to change this module to a more friendly piece of code.

Hi,

Thanks for looking into this.

I've been through the solutions for both Add-Ins, and I can not find any calls to Save the Inventor document apart from the save that the user performs.

I've posted some C# code below that is included in both Add-Ins, maybe something is off here?

private Inventor.ApplicationEvents m_appEvents;

// the code below is within the Activate() method in the StandardAddInServer class.
m_appEvents = g_inventorApplication.ApplicationEvents;
m_appEvents.OnSaveDocument += new ApplicationEventsSink_OnSaveDocumentEventHandler(m_appEvents_OnSaveDocument);
//

private void m_appEvents_OnSaveDocument(_Document DocumentObject, EventTimingEnum BeforeOrAfter, NameValueMap Context,
out HandlingCodeEnum HandlingCode)
{
    HandlingCode = HandlingCodeEnum.kEventHandled;

    if (BeforeOrAfter == EventTimingEnum.kBefore)
    {
        // Operation is performed
    }
}

Hi,

You said you did not use any code with .save etc.

But are you using commandmanager commands like:

Dim CmdMan As ControlDefinition
Set CmdMan = ThisApplication.CommandManager.ControlDefinitions.Item("Command Name")

CmdMan.Execute
CmdMan.Execute2 (True)

I do not use CommandManager for anything except adding buttons to the ribbon.

Hi,

What happens if you unload first the one add- in and than the other?

Still having the events twice?

I followed your suggestion now, and tested the Add-Ins one by one, and eventually found out what the problem was.

In the code block handling the save I had a check for document type, as I wanted to perform the operation on a drawing document only. The problem was that I was checking the active document type, and not in fact the document passed into the event handler. This became a problem as the add-in that was having this mistake was modifying the part belonging to the drawings as well, which in turn marked that part for save. So the duplicate events that followed was the save events for that part. 

It was a simple mistake, but this is what you learn from, right?
