I found on the web that restoring the TrayIcon can be made by catching the WM_TASKBARCREATED message.

It can be done by declaring this in the WindowProc fct :

// Somewhere in the code or header ....
UINT WM_TASKBARCREATED = 0 ;

// In the WindowProc
if (message == WM_CREATE)
    WM_TASKBARCREATED = RegisterWindowMessageA("TaskbarCreated");

if (message == WM_TASKBARCREATED)
{
  // Restore the icon ... how can i do it ?
}

I've tried de call TrayIcon::Show() method but it crash with a Shell_NotifyIcon Exception because in the Notify Fonction (TrayIconWin32.cpp) we have this line :

	if(visible) {
		nid.flags = NIF_ICON|NIF_MESSAGE|NIF_TIP;
		if(nid.icon)
			DestroyIcon(nid.icon);
		nid.icon = IconWin32(icon);
		String stip = ToSystemCharset(tip);
		int len = min(stip.GetLength(), 125);
		memcpy(nid.tip, stip, len);
		nid.tip[len] = 0;
		VERIFY(Shell_NotifyIcon(msg, (NOTIFYICONDATA *)&nid));

I change this to :

	if(visible) {
		nid.flags = NIF_ICON|NIF_MESSAGE|NIF_TIP;
		if(nid.icon)
			DestroyIcon(nid.icon);
		nid.icon = IconWin32(icon);
		String stip = ToSystemCharset(tip);
		int len = min(stip.GetLength(), 125);
		memcpy(nid.tip, stip, len);
		nid.tip[len] = 0;
		while (Shell_NotifyIcon(msg, (NOTIFYICONDATA *)&nid) == FALSE)
		{
			Sleep(100);
		}

but it change nothing ...

Helps please Razz
