Sample Code

The following example displays a message box if, for example, you try to create more than one KeychainItem for the same application.

Var NewItem As KeychainItem
If System.KeychainCount > 0 Then
newItem = New KeychainItem
// Indicate the name of the application
newItem.ServiceName = "MyApplication"

// Create a new keychain item for the application and assign the password
System.Keychain.AddPassword(newItem, "SecretPassword")
Catch error As KeychainException
MessageBox(error.Message + ". Error Code: " + error.errorNumber.ToString)
End Try
MessageBox("You don't have a key chain.")
End If

The following example uses an Exception block to display a message box if the application specified by ServiceName does not have a KeychainItem.

Var itemToFind As KeychainItem
Var password As String

itemToFind = New KeychainItem

// Indicate the name of the application whose keychain item you wish to find
itemToFind.ServiceName = "MyApplication"

// get application's password from the system keychain
password = System.Keychain.FindPassword(itemToFind)
MessageBox("The password for this item is: " + password)
Catch error As KeychainException
MessageBox("Can't find item: " + error.Message)
End Try
