Overlay windows example (layered windows)

[qWord]

Hello,
the following example is a reply to this thread.

The example shows a ways to create an transparent overlay for a window using layered windows. The overlay will have the same size as the target window, which must be a top level window. Events are managed using SetWinEventHook() function. Even the example is not perfect, but it shows the way to go.
It should be work for Win2K+, but I've only test it for WinXp and Win7(x64).
Other solution (preferentially with an example) are welcome.

regards, qWord

I ran it and it opened Winzip to add a file.

Hi,

  Works with Windows 2000.  Very interesting.  However some
odd behavior when used on a CMD.EXE window.  Screen dump
attached.

Cheers,

yep.
Probably it is that the console window is owned by an other process (conhost.exe on win7) than the actual application. Again an nice example that shows how special console windows are

Hi Dave,

   Oh well.  Google, CenturyLink, NPR, YouTube, and others
are leaving some not so subtle hints that I should do something.
Not to mention about a third of the links posted here in the forum.
But it works with the forum more pleasently than newer ones.
(A tiny bit easier on the eyes due to a flatter, duller appearance.)

Cheers,

I think when Netscape was popular, it was just them and I.E.

Hard to believe they have been gone for around 18 yrs.
