I'm using Urwigo to create Wherigo cartridge.
I'm using LUA snippets, in which I'd like to utilize the system time, however, I can't find out, how to get it?
If there's such option, will it be time returned by device (Android) or GPS system?
It appears that the Urwigo/Wherigo API supports the lua standard libraries. You can use the os.date function available in the os library.
The time returned will be the device system's time.

Is it possible to get system time in Dart ? e.g. in PC, we've a BIOS time which is a true system time (i.e. irrespective of what time the user can manipulate). I would like to know if it is possible to get the BIOS equivalent time in Dart in my Flutter app.
Thanks in advance.
I have 3 monitors, but I don't need them all turned on all the time. I can just shut them down with power button, but I want to use their standby mode, like Windows does when we let PC idle for a while - it shuts down monitors, HDD, etc.
But of course, I wanna keep using PC and let just that monitor on standby. Others must remain on and that one doesn't wake up even with me using PC.
Is it possible to do that? It would be great to have a shortcut like Winkey+1, 2, 3 etc to shut down and wake up each monitor.
An existing app with this feature is not likely to exist, but is there a Windows API function that can control monitor state, for each monitor in a MultiMonitor system?
The display control panel applet calls SetDisplayConfig to start or stop forced projection on a particular target
You can probably use MS Detours or some other API hooking tool to inspect the usage pattern of the API while using the applet to adjust display settings.
You'll want to try Display Fusion. You should be able to do what you're asking for using Monitor configurations.
I know I'm late on this but use DDC to control your display. You can easily create hotkeys that send a command via DDC to the display to turn-off. This would be equivalent to turning off the display using the button. Works like a charm for me. The only trick is that DDC command specs vary across monitor manufacturers but its not hard to find the right codes to send with the help of google.
Ready made tools also exist for this; search for anything that is related to DDC or EDID and you should find.
Be aware though that this does not remove the display from Windows which means that apps may find their way onto displays that are off and you will be looking for them.
I would like to know if it is posible to cast the audio taken directly from the microphone iOS device to the receiver. (in a live way)
I´ve downloaded all the git example projects, and in all of them use a "loadMedia" method to start the casting. Example of one of those:
- (NSInteger)loadMedia:(GCKMediaInformation *)mediaInfo
autoplay:(BOOL)autoplay
playPosition:(NSTimeInterval)playPosition;
Can I follow this approach to do what I want? If so, what´s the expected delay?
Thanks a lot
Echo is likely if the device (iOS, Android, or Chrome) is in range of the speakers. That said:
Pick a fast codec that is supported, such as CELT/Opus or Vorbis
I haven't tried either of these, but they should be possible.
Implement your own protocol using CastChannel that passes the binary data. You'll want to do some simple conversion of the stream from Binary to something a bit more friendly. Take a look at Intro to Web Audio for using AudioContext.
or, 2. Setup a trivial server to stream from on your device, then tell the Receiver to just access that local server.
sorry for this little bit strange title, didn't found a better one..
I've got the following situation:
I have a PC with an RFID reader connected via USB.
I now need a program which pops up when ab transponder was scanned the the RFID reader and shows the scanned value. (The reader just simulates keystrokes)
Problem: the value of the transponder is something like 0001230431, and I can't change it. (To prefix a hotkey combination or so)
So I have thought about using a global keyboard hook, check if three zeros where typed in, capture rest of data and when the 10 digits are complete, call the application through an automation object and show the number.
But I'm not very exalted about using a global keyboard hook. Many AV programs don't like them very much, they are not so easy to handle with Delphi and I guess that's not very resource-friendly for such a little task...
So I'm looking for an alternative solution...maybe somebody has an idea?
Big thx!
ben, you can use the RegisterRawInputDevices and GetRawInputData functions.
first you must use the RegisterRawInputDevices function to register the input device to monitor and then you can retrieves the data from the input device using the GetRawInputData function.
Check theses functions too
GetRawInputDeviceList retrieves the list of input devices attached to the system.
GetRawInputDeviceInfo retrieves information on a device.
Why not make sure the Delphi app with a text edit control has focus before the scan is done? Then the keystrokes will go straight into your Delphi app.
hallo,
I have a common question, I hope it is ok to ask it here.
I have a project, where I should develop a small appliation for BlackBerry. I know Java ME is the platform to do that (Browser and Widget are other opstion).
What I need to do is a samll application which pops-up after every call and asks the user if he wants to save(assign) this conversation (only the duration in minutes of the phone call is important) in his time-tracking database. He can click NO, but after it, he can start my application and see all unassigned phone calls and still he can assign them in the time-tracking db. This should happen offline and than be synchronized with the server via online connection.
My question now:
What APIs are to be used, for handling with the phone-calls?
Are there some downsides in this kind of application, which I newby can not see at first?
What about the different devices?
Thanks for any information you share with me, to help me avoid common newby mistakes!
Thnaks a lot.
That should definitely be doable, look at the PhoneListener interface to check when the phone call disconnects. What I would do is write the application as a system module, that will run in the background on startup. You can use an alternate entry point so that when the user clicks on your icon the application will create a GUI.
Edit: By the way BlackBerry uses an extended version of J2ME. You can ignore all the RIM specific extensions if you want and develop an app that will (theoretically) work on any J2ME device but you won't be able to use a lot of nice features including the PhoneListener interface. I doubt you'll be able to create this specific application with J2ME alone.
