You have to copy those database files in another machine too.

I copied it but i face the same error!!
is VS use some files in program file or any where!??

my error is "exception can not load file or assembly microsoft.report.viewer version 8.0.0.0 cultural =neutral public key =token .... or one of its dependences "

Error says that you must have to install appropriate version of .net framework on target machine to run your application.
