However, I can't seem to find an archive of the item from attachments anywhere, nor can I find any other code that might get me going. I tried contacting Alexandre directly without luck, so I'm wondering if, by some miracle, someone saved this code, or, alternately has something else that might serve the same purpose.

I didn't have the original zip, but found two units in one of my projects.

I was actually thinking of writing a 'bare-bones' example that leaves out all of the extra garbage and shows how to use per pixel alpha blending. The only real examples out there on the subject are written in C# and Microsoft C++... there is one Delphi example that was pretty good, but it had animations etc and didn't truely use per pixel alhpa blending to show a shadow under the form. In short, there was too much in it to really show a beginner (or someone that needs a simple reference) how to do it. If you (or the community) would like an example let me know and I am sure I can post something that will explain in easy to understand terms, how to render a Layered Window using per-pixel alpha in GDI+.

If you REALLY do not understand the concepts, I will write it in Delphi. Right now, I just don't have a tom of time on my hands. I have a kid on the way and am a poor programmer trying to make ends meet.

I'm sure the community at large would appreciate it, by I myself don't really need it at this time. I'm less interested in the esoterica of PNG and alpha blending, and more interested in the nuts and bolts of my applications. Of course, those are famous last words, aren't they? Six months from now I might be thinking "crap, I wish I had that example!" :-) I know that doing something and posting it to CodeCentral would be highly welcomed by many.
