i changed these lines in httpd.conf file

to

#listen 12.34.56.78:8080 listen 0.0.0.0:8080 listen [::0]:8080 

update
i have xampp installed in c:/xampp , has if wamp server not coming online or unable access files ?

its seems quite known problem xampp need go config file , find following line:

edit file : httpd-autoindex.conf

alias /icons/ "/apache/icons/"   <directory "/apache/icons/"> 

so looks this

alias /icons/ "c:/wamp/bin/apache/apache2.2.21/icons/"       <directory "c:/wamp/bin/apache/apache2.2.21/icons/"> 

after make sure pointing correct filepath.
note:-httpd-autoindex.conf located in c:\wamp\bin\apache\apache2.4.9\conf\extra

to secound error on browser write:

localhost:8080

and should work change http.conf file instead of saying 80 8080:

   <virtualhost *:8080> documentroot /www/example1 servername www.example.com  </virtualhost> 

restart apache.
