I wanted the same thing and ended up solving it without using guestcontrol. On my MacOS X host I have a folder (named Windows) that my vbox client running a Win7 has mapped as Z:. I use dummy-files to communicate between host and my clients like this:
On the Mac host:
- created one shell-script complete with an icon for each windows application I wanted to start in the Win-client. What they basically do is makes sure that the VirtualBox hasn't been started before and then creates a "start this particular application"-file in the shared folder that Windows can read after startup. Example of what such a script looks like is this:
# bail if vbox is already started/running windoze...
ps ax | grep -v grep | grep 'Windows 7' > /dev/null
if [ $? -eq 0 ]; then
echo "Sorry, Windows is already running."
# send a message to Windoze which program to start...
# startup Windoze in seamless mode
vboxmanage setextradata 'Windows 7' GUI/Seamless on
vboxmanage startvm 'Windows 7' &
Then on the windows client I have a matching script (BAT-file) in the Startup-folder that looks like this:
pushd "C:\Program Files\Omega Research\Program"
if exist Z:\start_ts2000i.txt start ORTrade.exe
if exist Z:\start_ts2000i.txt del Z:\start_ts2000i.txt
This way, any time I want to add a new client-startup icon on my Mac I copy the shell script, invent a new dummy file and add the matching startup lines in the BAT-script on the client. Works great and I think it is in line with Martys idea in the previous post.
