Adding Drag & Drop Like Windows Explorer?

The following website appears to show you you might do Drag/Drop that works like explorer does but I don't know what the code would be in VB, what exactly i'd need or anything else. It's a quite large code base just to make it so you get the same effect as explorer even though it seems to be API's or .dll's that should handle most of the work.

If the API's & .dll's available for this don't handle most of it I don't see why not because well if your meant to get the same effect why is it going to be handled mostly by code? I would think it would be as easy as passing an image or file/folder as string & then there the image is & possibly the functions you want to be allowed or text to be displayed for the drag action & then a little more to determine where your trying to drag to so what the text should be changing to.

Anyways heres the website which has a lot of the information/code in non-vb language, even when translated to VB using online tools I couldn't figure out what did what or what pieces I needed to get a basic drag action to work that has said visual information like explorer does.[URL]..
