This command should do what you are after:
~6=msg|Google Talk - Google Xmpp Client GUI Window|273|40080|0 ;
GoogleTalk - Disable/Enable all mail notifications
Anyways, to find this out I:
- ran Spy++
- clicked the "find" button
- restore the google talk window
- drag finder target over google talk window
- select parent "Google Talk" window in the Spy++ list
- right click, choose messages
- click logging options button
- in messages tab, clear all, then select "wm_command", ok
- right click log, clear all
- right click google talk tray icon, select "disable all notifications"
- right click the log entry in spy++, choose properties
- convert the hex to decimal
Note the window class was:
Google Talk - Google Xmpp Client GUI Window
The message was:
0x111 = 273
The wparam was:
0x9c90 = 40080
lparam was
0x0 = 0
thus the complete hoekey command is:
~6=msg|Google Talk - Google Xmpp Client GUI Window|273|40080|0
Hope that helps, when I get a chance I'll try to document this better
for people that want to do this themselves.
