Automated process hanging waiting for dialog

Tech-Archive recommends: Fix windows errors by optimizing your registry

I have an automated application that opens and manipulates Office
documents. Every time a document triggers a dialog to pop up, the
process waits for the dialog before it continues. After a little
research, it seems like I will need to use hooks and messages in the
Win32 API. Does anyone know how I could go about catching when a
dialog is porduced and sending it a message to close? Any ideas are
more than appreciated considering this is a time-sensative matter.
Thanks in advance!
