Disabling Accounts from AD

[rjcrane]

I am trying to create a windows form application/tool that speeds up the process of the way we disable employees account for leave our organization. So far I have created a form that allows the user to input the user name of the account and click a button that searches active directory and displays who the account belongs two, the next step that I am trying to implement is after clicking a second button the application would disable the account, move to the disabled users OU, update the description and hide from the global address list, however I am having issue link the returned account so that it can move on to disable the account, this is where your help would be appreciated in the best way forward. Thanks
