Regular Expression Find and Replace in Visual Studio 2003

Hey Experts,

Quick and simple question.

I have multiple code files where the Finally block in each method has an object.Dispose().. like this

Finally
       x.Dispose()
       Y.Dispose()
End Try

x and y can vary in names based on what object is being disposed. I want to do a Find and Replace in the entire solution where I have to find a match for Any object.Dispose() and replace it with
If Not Object is Nothing Then
     Object.Dispose()
End If

i.e
The code will be something like

objSQL.Dispose or lobjSQL.Dispose() or objOracle.Dispose() and I have to replace them with

If not objectname Is Nothing Then
   objectname.Dispose()
End If

where objectname could be anything that I match with a single Regular expression and use that in the replace too..

Any ideas or thoughts or the expression itself is appreciated.

Thanks,
Suj
