delphi - Text to speech in Vista -

-

i did creating ole object delphi in 2000/nt/xp following:

voice := createoleobject('sapi.spvoice'); voice.speak(...)

but not work in vista, how can make program speak text in vista?

i tried (d2009 on vista home premium) following code , works!

unit unit1;  interface  uses   windows, messages, sysutils, variants, classes, graphics, controls, forms,   dialogs, stdctrls, comobj;  type   tform1 = class(tform)     button1: tbutton;     procedure button1click(sender: tobject);   private     { private declarations }   public     { public declarations }   end;  var   form1: tform1;  implementation  {$r *.dfm}  procedure tform1.button1click(sender: tobject); var   voice: variant; begin   voice := createoleobject('sapi.spvoice');   voice.speak('hello world'); end;  end.

fyi, there nice paper on using speech in delphi programming brian long...

(very) late update:

for why might not work in vista , give ezerodivide exception outside ide, see other question: delphi sapi text-to-speech

unit testing - How to mock PreferenceManager in Android? -

-
i've written class using context , third party library , sharedpreferences preferencemanager . it's possible mock context , third party library can mocked using mocking framework, preferencemanager ? i have 2 methods: public void savestring(thirdpartyobject obj) { sharedpreferences apppreferences = preferencemanager.getdefaultsharedpreferences(mcontext); sharedpreferences.editor editor = apppreferences.edit(); editor.putstring(mcontext.getstring( r.string.preferences_string_name), obj.getstring()); editor.commit(); } and corresponding, loads preferences. it doesn't want mock instance of preferencemanager (which used in preferencefragment or preferenceactivity ). you want either: a mock sharedpreferences , in case can mock context#getsharedpreferences (which called preferencemanager#getdefaultsharedpreferences anyhow). you'll have make mock sharedpreferences.editor if preferences edited, above. know how moc...
