Question

Hide specific system tray icons

Asked by: Crash2100

Is there any way I can use VB to hide a specific system tray icon?  I found this API code that will hide the whole collection of tray icons, but I can't seem to figure out how to pull a single icon out of this so I can hide it.

Public Function HideTaskBarIcons()
    Dim FindClass As Long, Handle As Long
    FindClass& = FindWindow("Shell_TrayWnd", "")
    Handle& = FindWindowEx(FindClass&, 0, "TrayNotifyWnd", vbNullString)
    ShowWindow Handle&, 0
End Function

I also found this code that I think I can modify to do what I want, but I haven't figured out how exactly to get the buttons to hide.  I had to modify the API calls like this to get the list to work:
   http://www.visualbasiccode.com/Asp/showsn.asp?theID=11610

    hWndTray = FindWindow("Shell_TrayWnd", vbNullString)
    hWndTray2 = FindWindowEx(hWndTray, 0, "TrayNotifyWnd", vbNullString)
    hWndTray3 = FindWindowEx(hWndTray2, 0, "SysPager", vbNullString)
    hWndToolBar = FindWindowEx(hWndTray3, 0, "ToolbarWindow32", vbNullString)

I tried adding a For..Next loop to go through all the buttons, it finds the button I want to hide, but I haven't figured out how exactly to hide it.  Either that, or the system tray needs to be refreshed or something after it's hidden.
        Dim Ob As IAccessible
        AccessibleObjectFromWindow ByVal hWndToolBar, OBJID_CLIENT, UID1, Ob

        For iBtnIndex = 0 To iTrayButtonsCount
            If Ob.accName(Av(iBtnIndex)) = "PeerGuardian" Then
                SendMessage hWndToolBar&, TB_HIDEBUTTON, iBtnIndex, 0
                SendMessage hWndToolBar&, TB_SAVERESTOREA, True, vbNull
            End If
        Next iBtnIndex
