Visual Basic

Copy Code

Public Sub AnnObject_Lock(ByVal obj As AnnObjectBase, ByVal password As String)    If obj.IsLocked Then       MessageBox.Show("Object is locked. It will be unlocked.")       If String.Compare(password, obj.Password, False) <> 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

C#

Copy Code

public void AnnObject_Lock(AnnObjectBase 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. It will be locked now.");        obj.Lock(password);     }  }

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 AnnObjectBase.Unlock to unlock this AnnObjectBase.

If this method succeeds, password will be stored inside the object and can be retreived with the Password property.

An object must be unlocked in order to change that object in automated mode.
