Extracting text / keyword searches from a powerpoint presentation

[rp666]

Not sure if this belongs in this should have been put in the data access forum. If so, apologies in advance.

I am using vb.net in a web application to go through a list of ppt files I have created from the contents of a directory. My intention is to either:
a) extract text from them so I can create a table of keywords that will later be used in keyword searches.
b) if one exists, to use a builtin keyword search function.

However, I am unable to find anything in the Office.Core namespace or in the PowerPoint namespace that look like a text search or read function. Is there a builtin way to either:

-extract readable text from a ppt presentation, slide and notes sections?
-do keyword searches on a ppt presentation, slide and notes sections?

This is the bsaic idea:
--

Dim myPowerPoint as PowerPoint.Application
Dim pptFiles() as string
pptFiles = Directory.GetFiles(path, "*.ppt")


For x = 0 To pptFiles.length - 1

Dim targetFile As String = pptFiles(x)
Dim prsPres As PowerPoint.Presentation = myPowerPoint.Presentations.Open(targetFile, True, False, False)


'insert code top read text strings from ppt presentation

tergetfile = nothing
prspres = nothing

Next

--

You should google on how to use the IFilter interface to search powerpoint files
