How can I make my program appear in the system tray of the Windows?

What I want my program do is to keep track of time regularly (using
timer) and do something behind the scene. (like a scheduler.)
So, I want to make my program disappear from main desktop and appear in
the
system tray.

What can I do?

This puts a green tick in the SysTray, then changes it to a red minus
(No Entry sign in UK), then removes it.  Delays in between (sleep).

I was going to send a traffic light sequence but I'm not certain whether
it's using a generally available DLL.  I think most will have
INETCPL.CPL

You can use any DLL that has icon(s), probably .EXE also ?

Have fun,

VisualuRuby makes this pretty easy:

Here is the example script for the tray icon stuff:

Hi,

Very neat.  I found the icons in C:\WINDOWS\SYSTEM32\INETCPL.CPL'
though.

Do you have pointers to more info on this API?  I am not really a
windows programmer.

Thanks

Tom

Ah, thanks.  That may apply to the majority, then.

I support Ryan's point about VRuby/SWin and I should have mentioned it.

The traytest.rb example he linked to should be more appropriate to the
original poster than I thought.

My example would need a Windows message loop to do anything useful like
minimizing a GUI or waking it up again by clicking on the tray icon.
VRuby implements that and, of course, most Windows users will have it
installed already if they used the RubyForge one-click installer.
