Set any page as a home page programmatically in Sharepoint 2010

Hi techies,

In one of my event receiver i tried to set a page as home page but couldn't succeed in it.

Here is the code snippet which i tried:

SPFolder libraryFolder = newWeb.GetFolder("Page");
                SPFileCollection files = libraryFolder.Files;
                SPFile newFile = files.Add(newFilename, stream);
                libraryFolder.Update();
                stream.Close();
                libraryFolder.WelcomePage = "Home.aspx"; //custom landing page    
                libraryFolder.Update();

Anybody came across the same issue.

Please  let me know.
