Introduction

Quick and dirty POC that allows one to drag and drop text into any HTML element in an IE-based web browser.

The Scene:

It's early 2010 - and the product's use of an external control (CSEXWB) is reportedly causing issues in the newly released Windows 7. We have a problem - but support has been holding the fort for now, but we need a fix - the sooner the better.

Another (brilliant) senior dev Scott discovers that the issue is in a COM control part of earlier mentioned control - and we don't have the sources to it/or we can't compile C++ code. Either way, so we spitball:

1. Either find an alternative way thru possibly JS? Me: That would still require a control that accepts Drag & Drop events.
2. Me: How about I check my extensive Delphi collection and see if I wrote something like this in the past in Delphi...

I didn't find a wrapper control but I dive into the Windows/IE API. A few days later, I pass the control back to Scott. To my absolute surprise, shock and horror, he implements it into the product within a day. He says 'it worked with a few changes' (most likely the highlighting part/drag over code as that required more knowledge of JS...). We regression test everything. All looks good and it's pushed to prod.

How to compile:

1. Load in Visual Studio.
2. Compile/Build
3. Run!
