Making tray icon visible after explorer.exe crash

[FusionGuy]

Hi,

I have an app that minimizes to the system tray (no problems there). The
issue is when/if explorer dies and my app continues to run, however the icon
no longer appears in the system tray. How do apps like MSN Messenger and
others manage to keep their tray icons visible after an explorer crash?
Thanks.

Explorer broadcasts the message
RegisterWindowMessage("WM_TASKBARCREATED") after the taskbar has been
(re)created. At that time you should add any notification icons again.

The .NET NotifyIcon component handles this message internally so if
you use that, it should simply work without any extra work required.
