Automate Excel from vc++ .net as child

[Koh Kah Chin]

Hello world,
i'm very new to automation office.
i'd created a dialog base application to automate Excel.
everytimes it run the Excel in another new window, but, when i closed my
dialog (application) the Excel does not closed. Can i set the Excel as a
child application of my dialog?
That is when i close my application (dialog) the excel is close as well!
I understand that if my application is SDI / MDI i can simply embed the
Excel in the document, and problem solved, but my application is dialog
based.

Thank you in advance.
