how can we use the permalink (Post name) in wordpress..?

Dear me alredy have mensioned that in permalink settings..butt still when me open the my page its was show 404 page error..

i see..
One thing i can think of is that u're permalink settings are not updated. Many a times if u've hosted on a windows server and your htacess is not writeable wordpress gives u an error saying that your permalinks could not be updated coz htaccess is not writeable. In that case you need to create a web.config and addin whaterver wordpress gives you.

Is that the reason?
