Hi,

I saw this problem was already posted once, but was solved by itself.

We're using add-in express for an Excel Plugin, using VS2005.

There are many times that the EXCEL.EXE process stays in the air even after closing it (when the add-in is present), and when opening Excel again, we can see the add-in menu/toolbar, but they are empty and non-functioning (like the dll is not loaded or something).

When killing the process from the task manager and opening Excel, everything works fine again.

What can be the cause of this?

Thanks for your help...

Hi Keren.

Can you please review the add-in code and use the Marshal.ReleaseComObject method with Excel interfaces if they are no longer used.

P.S. Note that we take up your forum requests in the order we receive them.
Besides, it may take us some time to investigate your issue. Please be sure we will let you know as soon as the best possible solution is found.

Hi Sergey,

Can you please clarify?

1. What do you mean "with Excel interfaces if they are no longer used"? When is that? What are Excel interfaces?
2. Can you give me a code example?
3. Is this issue familiar?

Hi Keren.

This is not the issue. Please read about the Marshal.ReleaseComObject class in the VS Help. You can send me the code of the addinmodule if you wish. I will change it.

Keren,

Also you can look for the ReleaseComObject method use in my article http://www.add-in-express.com/creating-addins-blog/2006/08/17/outlook-not-closing/.

Hope this helps.

Thanks Andrei and Sergey.

In the addinModule I have the following property:

public Excel._Application ExcelApp
{
get
{
return (HostApplication as Excel._Application);
}
}

I am using it in many places.
Where and how should I call Marshal.ReleaseComObject ?

Thanks!

Hi Keren.

This code is OK. Is it all that you have in the addinmodule?

Yes, This is the only place I have a reference to Excel._Application.
As I said, I'm referring this.ExcelApp in many places.

Thanks

Keren, do you use Excel interfaces (e.g. Range, Workbook, Worksheet and so on) in the add-in code? If so, could you please send me the code? I will try to help.
