      • I have just been learning about finalizers in C++/CLI and saw quite a bit of sample code that duplicated the same resource-freeing code in both the destructor and finalizer.

So I have to questions: Am I doing the correct thin

      • Hello everyone, Is there an equivalent to SendKeys.Send in C++ I have looked into keybd_event and SendInput, but to my knowledge you can only send one key at a time with those functions. Thanks for any help. Edit: I'm not using the .Net Framework so I can't use any of that stuff.
