PowerTip of the Day, from PowerShell.com:
When you write functions that accept credentials as parameters, add a transformation attribute! This way, the user can either submit a credential object (for example, a credential supplied from Get-Credential), or simply a user name as string. The transformation attribute will then convert this string automagically into a credential and ask for a password.
function do-something {
param(
[System.Management.Automation.Credential()]
$Credential
)
'$Credential now holds a valid credential object'
$Credential
}
When you run do-something without parameters, it will automatically invoke the credentials dialog.
