Automatic Date Inserted Into Textbox

Ok so im trying to have a blog type thing as part of a website im doing.

On the create new blog page I have a formview conponent which is set to show insert mode as its default. And the 4 textboxes in there are 1) Title, 2) Posted By, 3) Date and 4) Message. So once these are filled in and the insert button is clicked then it sets stored on the database and shows up on the blog page.

One question though. Is there a way to have it so the Date textbox has the date (and time) automatically inserted into the textbox when the pages loads? Rather then the user having to type it in themselves, which can lead to errors if it is not typed in the correct format.

Also is there a way to do the same for the "posted by" textbox? Where the name of the user who is logged in will automaticly be in this textbox when the page loads?

 Any help would be greatly appriciated!!!!

Thanks!
