Modify tooltip - Mouse over file (.xml)

[AeJai]

I am developing an application that saves files as different file types. I am concerned with the .XML. How do you modify the tooltip when the operator hovers his/her mouse over the file if the file type is .XML? The XML document is defaulted to display the type, date modified, and size in the infotip (tooltip). Is there any programming I can do using C++/MFC to modify these contents? I have been told look into using shell scripting, but this application is to be installed on other machines with Windows XP.

What context is the user hovering over the file in Explorer or in you own application ?

You need a shell extension http://www.codeproject.com/shell/shellextguide1.asp[^] Look for code with with QueryInfo handler (shell version 4.71+)
