hi,

while adding a new contact at salesforce.com from 'Create New Contact' screen and clicking 'Save' button, i want the data entered to be validated from an external application at the click of a button.

how would this be possible? what integration mechanism could be used (web services, custom objects/tabs etc)?

thanks in advance,
dharamvir
