I am trying to modify a Windows stack to alert the user when a
particular event happens while the app is in the background or
minimized. Something like mergNotify, but for Windows, would be ideal.
My first thought was to change the taskbar icon, like Outlook does
when I have a new email or Skype does to display my status. The forum
and dictionary proved "set the icon to (some ID)" doesn't work on
Windows[1], but I could use the still-undocumented "set the statusIcon
to (some ID)" property[2] to change the system tray icon.
This sort of worked as I was able to make a little repeat loop that
changed the statusIcon[3] from one image to another and then back
again to create an attention grabbing area at the bottom of the
screen. My problem with this is that after the first time that alert
is acknowledged, via statusIconDoubleClick in this case, any
subsequent statusIcon changes are only displayed in the "Show hidden
icons" of the system tray which in essence buries it from the users
view (until the stack is relaunched). I confirmed this behavior with
the Sons of Thunder product STSTray[4] which seems to suffer from the
same problem.
Can anyone suggest a LiveCode native way to alert a Windows user? The
closest I could find is to use "do as VBScript" with an AppActivate
command[5], but was hoping for something using LC script directly
(although this forced me to learn some VBScript and use the "do as
alternateLanguage" command[6] which were both foreign to me).
put "Set objShell = CreateObject(" & QUOTE & "Wscript.Shell" & QUOTE
& ")" into tScript
put RETURN & "objShell.AppActivate" && QUOTE & "taskbar_icon_demo" &
QUOTE after tScript
do tScript as "VBScript"
