how does the .RGS file works

In the .rgs file, there are some registry info, and I want to know how does the info in .rgs file added into regetry?

I have a project AAA and it will generate the file AAA.DLL, and there is a file xxx.rgs 开发者_高级运维which contains the registry info, and the AAA.DLL is built, then it will be deployed to another machine B, so I don't know how the registy info can be added on machine B, do I need register AAA.dll using regsvr32 command?

Usually your code calls CComModule::UpdateRegistryFromResource() which in turn passes control to a special mechanism implemented in ATL which does the job - parses the resource that was produced by embedding the .rgs file into the module and edits the registry. ATL comes with sources so you can just read how it is done.
