Remote Desktop - Cmd+D - save without closing question

Question

I'm trying to write a script that will allow me to quit an application (SketchBookExpress) without saving changes.  I'm having trouble with the syntax for the "Don't Save" (cmd+d).  The script runs but stops at the on screen Save/Canel/Don't Save dialog box. 
What I have tried is the following:
osascript -e 'tell application "SketchBookExpress" to activate';
osascript -e 'tell application "SketchBookExpress" to quit';
osascript -e 'tell application "System Events" to delay 0.5';
osascript -e 'tell application "System Events" to keystroke "d" using {command down}';
And I've tried:
osascript -e 'tell application "SketchBookExpress" to quit';
osascript -e 'tell application "System Events" to delay 0.5';
osascript -e 'tell application "System Events" to key down command';
osascript -e 'tell application "System Events" to keystroke "d"';
And, I've also tried:
osascript -e 'tell application "SketchBookExpress" to quit';
osascript -e 'tell application "System Events" to delay 0.5';
osascript -e 'tell application "System Events" to to keystroke "d" using {command}';
I'm very new to Remote Desktop and AppleScript and would appreciate any help you can provide about how to close an app without saving it.
Thanks.

I think you need to turn this on its head.
SketchBook Express is not scriptable, so you can't use the 'normal' method, which would be:
tell application "SketchBook Express" to quit saving no
The problem with your approach is that AppleScript is serial - each command is executed in turn, so it's waiting for the app to quit before executing the next command (unless you run all these commands in parallel, but that's a different issue.
However, there's a simpler solution to your problem:
killall SketchBookExpress
This sends the Kill command to the app, quitting it, bypassing the whole 'Save changes?' process.
This is a standard shell command, so you don't need AppleScript (or osascript) to run it. If you do want to wrap this in a larger script, just use 'do shell script':
do shell script "killall SketchBookExpress"
