I am developing a GPS application and during startup I want to check if the GPS is active - if not I want to enable it. How can I do this?
Your application cannot control the status of the GPS.
You can, however, start and stop data acquisition.
Look into System.Device.Location

Since, I am new to Windows Phone technology ,so I want to detect touch event of Windows phone screen that means if I have touched on any screen on Windows Phone not necessary in application only outside of application (like start screen,settings screen) so can I get that touch event or any pixel information regarding that touch.Any help would be greatly appreciated .
Thanks you.
To protect the privacy of the user, there is no way to globally hook all touch events from an application. You can only react to events within your application.
Further, an application cannot access the screen while other applications are active. That would be a significant privacy hole if an application could record the actions of other applications.
I am developing a windows phone app that uses users current location, I am making the app in 7 OS. My question is, Can I track the location in background, that is when the screen is locked?
I know this is a possibility in wp8 as it provides us with GeoLocator class, but can I achieve this in wp7? I am basically making a runtracker app hence I would like my app to track the location even when its in background, is it really feasible?
Your help is always appreciated!!
It is possible to keep the app running under lock screen, as it does, for example, Endomondo app.
Using Idle Detection, you can keep the app on, although screen is locked, and you can keep on tracking the location. Actually, it is not running in background, but in the foreground. Just the screen is locked. So, be careful not to drain user's battery.
You have to set the PhoneApplicationService.ApplicationIdleDetectionMode property to Disabled, for example in InitializePhoneApplication() method in App.xaml.cs:
PhoneApplicationService.Current.ApplicationIdleDetectionMode = IdleDetectionMode.Disabled;
Note that there are special certification requirements for this type of apps. Refer to section 6.3 (Apps running under a locked screen) of the following page:
Additional requirements for specific app types for Windows Phone
I got the same problem in one on my apps..
I don't think it' s feasible for wp7..
Bt if you want to do it with wp8 you can refer following link.

And to know about background supported and unsupported API's http://msdn.microsoft.com/en-us/library/windowsphone/develop/hh202942%28v=vs.105%29.aspx/css
GeoCoordinateWatcher Class exists in WP7, but here is the documentation from MSDN -
This API, used for obtaining the geographic coordinates of the device,
is supported for use in background agents, but it uses a cached
location value instead of real-time data. The cached location value is
updated by the device every 15 minutes.

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.
Is there any way switch on/off flight mode programmatically in Windows Phone 7.5. What I want to do is create background task which will be check time and switch on/off flight mode.
Thanks in advance.
No, this functionality is not available.
It was a design principle behind the platform that applications should not be able to do things without the user knowing it.
If such functionality was available then it would be possible for an app (either deliberately or accidentally-though a bug) to get the devices state in a setting other than what they user may expect. In such a scenario users will typically blaim the phone/platform for what has happened, not a misbehaving application.
Though you cannot programatically do it (as others have mentioned), you can send the user directly to the proper page in the settings panel and allow them to do it. Here's an example of using the ConnectionsSettingsTask:
http://msdn.microsoft.com/en-us/library/hh394011(v=VS.92).aspx
You would want to set the ConnectionSettingsType property:
http://msdn.microsoft.com/en-us/library/microsoft.phone.tasks.connectionsettingstask.connectionsettingstype(v=VS.92).aspx
To 'AirplaneMode'.
So far, to turn on and off the GPS device in Wp7, I do it in Settings Menu. Wonder If this can be done in code?
Thanks
---------- Update
Sorry for the confusion. Instead of turning GPS on and off, What I really mean is how to turn on and off the LOCATION in the Settings Menu of Wp7.
You can get the GPS data but you are not able to turn the sensor on or off via your application.
The most you can do in your application is start the geolocation data acquisition and stop it.
Windows Phone 7 apps should not change global settings for the phone.
You should have your own settings page in your app, with it's own toggle for whether or not your app should use the location data.
Then you check your setting before you access the location data.
Why would you want to turn it off globally?
