How does tray icon redisplay after explorer crash?

[docbrazen]

Hello,

I was wondering how DC++ knows when to redisplay the tray icon in the event of an explorer crash? The only way I have heard of is to constantly redisplay the icon at set intervals. How did DC++ manage to fix this problem? I noticed you guys fixed it in version 0.174. Is there a way to detect if explorer crashes?

Thanks,

in MainFrm it looks like this:

Code: Select all

trayMessage = RegisterWindowMessage("TaskbarCreated");

Code: Select all

MESSAGE_HANDLER(trayMessage, onTray)

Code: Select all

LRESULT onTray(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& /*bHandled*/) { 
   updateTray(true); 
   return 0;
};

a google query for "RegisterWindowMessage(\"TaskbarCreated\")" turned up:
