Shell_NotifyIcon. Unfortunately it's sent directly to shell32.dll so you'll have to find out a way to "listen in". |

Thanks, that helps a lot. Now if you just so happened to know what message, and how they send it...  (Do they look for a special window, send it to all the windows, etc?) |

The System Tray works like this: people call an API to register a tray icon (provide a tooltip, icon, window handle, process pointer), and later one to unregister them (that's why programs that crash still have their icon there but it disappears when you hover it - Windows sends a mouseover event to the program, notices that it has quit and removes the icon on its own). Explorer.exe receives those messages somehow - you'll have to hack a way to make your shell get those messages instead. |

Hmm, so you have to use an image list for icons? Nuts, I was hoping to avoid that. Anyway, I figured there must be some window attribute that tells it? (Can't just be constantly monitoring for it, since if you close/restart it or it crashes, the icons are all still in it.)
Anyway, this code won't work... All it does is patch into the existing taskbar. Mine is a replacement taskbar/shell, so explorer.exe won't be running. |

I believe this website should help you a bit: http://skyscraper.fortunecity.com/gigo/311/winprog.html
There's sample C++ code to enumerate the currently displayed tray icons. It seems to actually hook into the tray, which I presume is some kind of hacky way of doing it. |

that is my understanding of it as well. I was reading up on a document (rather dated, keep in mind) that suggested just that: there is no exact way to determine if a window/form is being kept in the system tray. I suppose if you're emulation of the system tray is targeted at a specific program, your idea could still work. Otherwise, if you are not targeting a specific process, i you might be out of luck.
if you're going to be messing with the taskbar though, look into SHAppBarMessage |

Can't help you with this one... I haven't done any work involving the system tray ever. But I'm kind of interested... so if you find out elsewhere, could you post your findings (or a link to them) in here? ^^ |

I've been working on a custom taskbar using EnumWindows, and it's working good, but I've hit a problem with emulating the system tray. I need to know how to tell what windows are in it, get their icons, and send mousemove/click/etc messages to them when moving/clicking the tray icons. Any ideas? |
