Get control of opened powerpoint slides to perform search.

[mrnobody]

Hi,
I'm currently doing a program to search for text in powerpoint files using interop in vb.net 2005. When a user does a search, it will open the powerpoint (.ppt) file and do the search. This is working fine.

What I want to achieve next is if the powerpoint file is already opened, I want the program to search for text in the opened powerpoint file (without opening the file again in ReadOnly mode).
How can I do that..? I mean, I need to first search the list of opened program to see if the powerpoint file is opened and then i need to somehow cause my program to gain control of the opened powerpoint file before I can do a search right..? How can I do that..?

Can somebody please advice..? Thanks.

System.Runtime.InteropServices.Marshal.GetActiveObject() method. Have a look at - http://support.microsoft.com/?scid=kb;en-us;316126&spid=2509&sid=global
