crystal reports connection string

[vinayak.v]

hi..

i want to override the connection  string of crystal reports..

is there any way that i use the connection string as shared datasource.

MY PROBLEM BEGINS:

i've 50 reports with the connection string vsspl-005\sqlexoress

but i've changed my connection string vsspl-002\sqlexpress.

there is only one way that i dont want to do i.e individually change the connection string of each crystal report

using database experts..

is there any way that the connection string should be assigned as shared datasource..

or any other way..

Please please help me i'm trying this since from one week..

inform me whether it is possible or not.

if possible send me the code..

if not.. then reason please.

i'm fedup of this..
