| C# | Copy Code |
|---|---|
public void AnnObject_Lock(AnnObject obj, string password) { if(obj.IsLocked) { MessageBox.Show("Object is locked. It will be unlocked."); if(string.Compare(password, obj.Password, false) != 0) MessageBox.Show("Invalid password!!"); else obj.Unlock(password); } else { MessageBox.Show("Object was not locked.

| SilverlightCSharp | Copy Code |
|---|---|
public void AnnObject_Lock(AnnObject obj, string password) { if(obj.IsLocked) { MessageBox.Show("Object is locked. It will be unlocked."); if(string.Compare(password, obj.Password, StringComparison.Ordinal) != 0) MessageBox.Show("Invalid password!!"); else obj.Unlock(password); } else { MessageBox.Show("Object was not locked. It will be locked now."); obj.Lock(password); } } | |
| SilverlightVB | Copy Code |
|---|---|
Public Sub AnnObject_Lock(ByVal obj As AnnObject, ByVal password As String)
If obj.IsLocked Then
MessageBox.Show("Object is locked. It will be unlocked.")
If String.Compare(password, obj.Password, StringComparison.Ordinal) <> 0 Then
MessageBox.Show("Invalid password!!")
Else
obj.Unlock(password)
End If
Else
MessageBox.Show("Object was not locked. It will be locked now.")
obj.Lock(password)
End If
End Sub | |
Remarks
Only unlocked objects can be locked. If an object is already locked, it will stay locked with its original password. You must pass the same password to AnnObject.Unlock to unlock this AnnObject.
If this method succeeds, password will be stored inside the object and can be retrieved with the Password property.
An object must be unlocked in order to change that object in automated mode.
