Completes the asynchronous operation started in BeginChangeWorkingDirectory.
true if the directory was changed successfully.
Before calling BeginChangeWorkingDirectory, you need to create a callback method that implements the AsyncCallback delegate. This callback method executes in a separate thread and is called by the system after BeginChangeWorkingDirectory returns. The callback method must accept the IAsyncResult returned by the BeginChangeWorkingDirectory method as a parameter. This parameter may then be passed to the EndChangeWorkingDirectory method to complete the operation.
