PowerPoint : How to modify text in Shape object without lost text format

[kylix2001]

Hi all

I am developed a Add-in for PowerPoint (Visual Studio 2005 and Office 2003)

I want replace any text part of shape, but without lost text format.

I have used (this code) for first word replace, but all text format from
shape is changed.

shapeTmp.TextFrame.TextRange.Words(0,1).Text = "any".

Suggestions? ;-)


Thanks all
