I don't know the actual terminology for it, but I am trying to create a selection box within a form. Using the left mouse button. Similar to this image https://www.dropbox.com/s/257aeqon32ca5cn/Screenshot%202018-02-09%2018.46.32.png?dl=0 Is there any way to get the clean animation similar to what windows can do maybe using direct draw or directX?

Edit: I believe it may be called a drawReversibleFrame

What I have tried:
