Using java to listen for a keypress when the program is not in focus

I want to set up a program where no matter what other program I'm using, when I press Ctrl+F1 my program will take focus and run another function or two. Is this possible and if so how can it be done?
Thanks.

Ok Mr. Smartass...Ok
I'm building a browser that is always open, and when
a user presses Ctrl+F1 (notice, just those two keys,
I don't care what else they press...) the browser
will open up. That way, you don't have to wait for it
to load all the time.You have two ideas here. One is having a universal key map that always gets ctrl-f1 sent to your app. The other is a program that is constantly running so that you don't have to wait for it to open up. The former is not possible (and this is a good thing) As warneria and I have been saying, it is bad design for an app to try to force an OS to implement this kind of feature.
If you're not going to help please don't post at all;
it's a waste of time for both you, me, and anyone
else who may need help on the same subject. Why wouldBelieve it or not, I am helping you.

How to listen for key press when air app does not have focus

Hi,
I am developing a application in air and part of the functionality I need is the ability for the app to listen for when a specific key is pressed, even when the air app does not have focus.
Is there support for this for windows or mac? If not, how might this be accomplished? ANE?

Do you know what happens if you delete the icloud account from an iphone 4s? Will it delete the pictures, documents, etc. from the phone, or just unlink the icloud from the phone? I want to associate a different icloud account to the phone.

[SOLVED] - Thunderbird constantly crashing, especially when using Add Ons Manager, but sometimes just when the program has been sitting open.

Hello,
I was using Thunderbird earlier today when the power went out in my neighborhood. Since the power has been restored Thunderbird has been crashing early and often. I can't get the program to open unless I rename or delete the "extensions" folder in ~\Library\Thunderbird\Profiles\<Profile Name>
It will crash immediately if I go to Tools--> Addons. Eventually it will just crash from just sitting open in the background. I've attached the crash report below. I'm on OSX 10.10.1
I've tried deleting and reinstalling Thunderbird (both the current and previous version)
I've tried repairing permissions
I've tried using Time Machine to restore the entire Profiles folder from before the power outage.
Any suggestions? I've been using Thunderbird for years and I'm quite comfortable with it, but might have to switch to Postbox if I can't fix this.
Thanks.

Is there a way to turn off calendar notifications for ical and outlook when the program is not active?

Hi - i'm finding these to be a little bit annoying, anyone know how to do this? The Outlook ones bug me more than the iCal ones. Also, i'm wondering if that is hurting battery life to have that running the background.

I'd install Better Touch Tool (free). Add two gestures for Finder ONLY that have "No action" associated with them. This disbales pinch/zoom on the desktop AND in any Finder window, but not in any other application.
If you'd like to occasionally use pinch to zoom in the Finder (to zoom into a photo thumbnail for example), then add two more gestures, again for Finder ONLY - but this time also selecting one of the modifier keys (e.g. "Option" key). For these gestures set as "Use Apple Default or do nothing".
Together, this enables disabling of the zoom feature (to prevent accidental zooming of the desktop icons for example). But whenever you'd like to zoom into a document or photo etc in a Finder Window (which are also now disabled), you can now simply hold down "Option" key and the Pinch functions work again.
This solution works for me on 10.6.8

Hello, I have created a distribution kit for my program.The problem is that the when the program is installed onto another computer, it fails to communicate with field point (Using FP-AO-200 and FP-AO-1000). Help is greatly appreciated, Thanks faen9901

Hi Everyone,
I have a program that sends information(analog output) to lab windows cvi in the form of a text file or user input.
The program runs on the computers that I have the field point explorer and lab windows cvi installed on. In order to run the program without always installing labwindows/cvi and field point; I wanted to create an executable file that could be load on another computer.
I used the create distribution kit part of labwindows/cvi to do this.After creating the distribution kit, I then installed it
to another computer.
My user interface appears on the screen, when the user clicks on the exe. file, but no data is sent to the field point module. I know that the data is being read from the user and textfile because in it appears in the uir.
The following are some details about the problem:
1. On another computer without labwindows/cvi and field point explorer not installed - no data is sent to field point module
I know this because a current is being read on the current meter connected to field point module.
My questions are the following:
1. What are the possible reasons for the data not being sent to the field point module?
2. Do I still need to create an iak. (Installing Field point Explorer) file stored on any new computer that I install my created distribution kit file too?
Thankyou very much for any help that you can provide. I greatly appreciate it.

1) If you do not install FieldPoint Explorer, the FieldPoint Server is not installed so there is nothing on the target computer that knows how to talk to the FieldPoint system.
2) Yes, you need an IAK file on the target computer. Assuming the settings (i.e. com port#) are identical you can simply include the iak file as part of the distribution.
3) You also need to include as part of your installer the file "fplwmgr.dll". If this file is not installed, your program will not be able to access the FieldPoint Server. Alternatively, this file is installed automatically if FieldPoint Explorer detects LabWindows/CVI or Measurement Studio Development versions on the target computer or if you choose to do a custom FieldPoint Explorer installation and
choose to provide LabWindows/CVI support.

Hi, ireland a.
I would recommend closing any open applications in multitasking and restarting the device. If unfamiliar with multitasking, I have included a screenshot on how to process an application close.
iOS: Force an app to close
Once these steps are processed, attempt to send the photo again.

My ipod keeps searching for network, even when the network info is all set properly. It has suddenly started doing this. Also, buffering forever... I have tried to reset the network few times, but not working.

Hello Nazer_502,
I would be concerned too if my iPhone was acting this way. It sounds like it is overheating and not holding a charge. I recommend following the steps listed below when experiencing an issue like this:
Battery life seems short
Click ( www.apple.com/batteries/iphone.html) for tips on how to prolong iPhone's battery life.
Try turning iPhone off and then on again.
Connect iPhone to iTunes and restore iPhone.
If the screen shows a low-battery image, the battery is low on power and needs to charge for up to ten minutes before you can use it.
When charging iPhone, make sure to leave it charging until it is fully charged. You'll know the battery is fully charged when the battery icon in the upper-right corner of the screen looks like this .
Note: When charging using a computer, don't connect iPhone to a keyboard. Also, the computer must be turned on and not in sleep or standby mode. If iPhone is connected to a computer that's not turned on or is in sleep or standby mode, the iPhone battery may drain.

"Waiting for real-time target (RT PXI target) to respond" error when the program waits interrupts

Hi there,
I have developed an application to detect interrupts generated by a electronic card and act in consequence. The program has been developed in labview but it calls a dll; that was created with labwindows. The dll is programmed to open the visa communication, enable events and install the interrupt handler and when an interrupt is detected, it reads the value of the different registers of the card and returns it to labview to visualize them.
The problem is that when the program waits for an interrupt, a prompt appears with the message "Waiting for real-time target (RT PXI target) to respond" and the only option I have is to click on the button to disconnect from the pxi or just wait. If I wait and I generate an interrupt, the prompt disappears and the application visualize the data like it was expected.
To wait for the interrupt the following code has been programmed in the function:
while (flag == 0)
Sleep (1000);
When an interrupt occurs, the value of flag changes to 1 and the function continue without any problem. I am not really sure, but probably here is the problem and probably this is not the best way to wait for an interrupt because the sleep function suspends the thread for the configured time, but at least the computing load in the PXI is between 0% and 1%. I was wondering if somebody knows how to wait for an interrupt without "lost" the communication with the PXI and if there is a better way to do it.
Any answer will be welcome and thanks for them,
Jaime
Solved!
Go to Solution.

Hello Naity,
First of all, in which thread runs the waiting process? Is it scheduled in another thread than the function setting the flag?
It scheduled in the same thread that I use to configure the communications and configure the card. Anyway, here is the pseudo code of the function interrupt that I programmed under labwindows,.
char* interrupt(void)
1. Open visa communications
2.Install handler interrupt --> status = viInstallHandler (instr, VI_EVENT_PXI_INTR, IntrHandler, VI_NULL); // the function IntrHandler will be called when an interrupt occurs
3. Enable event PXI interrupt
4. Wait
while (flag == 0)
Sleep (1000);
5. Visualize the data coming from the interrupt (registers and values measured with the card)
6. Uninstall handler interrupt
7. Close visa session
The interrupt handler function IntrHandler is called immediately when an interrupt occurs and the pseudo code is like this
ViStatus _VI_FUNCH IntrHandler(ViSession instr, ViEventType etype, ViEvent event, ViAddr userhandle)
1. Disable some functions of the card to avoid damages.
2. Read registers and put them in a buffer
3. Change the value of flag ---> flag = 1;
In labview, I call the function interrupt with a call library function node (see the capture attached) and the program reads and saves the data from returned from the function.
Secondly, I am not sure this method is the most elegant. You could for example register an event with the function and, insteand of setting a flag to 1, trigger the event and schedule it in another thread (if the function is thread safe). This could reduce your CPU Load even more and seem a bit cleaner to me.
I've never used events before in labwindows but I will try to do it in this way. But anyway, I suppose that I should; somehow, wait the event to occurs in labview while the waiting for the event is programmed inside the dll...and probably the same prompt that i am trying to avoid is going to appear again, because I am not returning the "control" to labview (I mean, labview executes the dll and waits for the event to occur. Then the execution of the labview program is stopped in the call library function node executing the dll)
Third point, which environment of development are you using?
I am working with LV 2010 sp1 and Labwindows cv 10.0.1 and with the real time module.
I did also another test, I divided the program in different functions, one to initialize the communication, another to wait until a interrupt has been detected and the other to obtain the data from the interrupt and close communications. With labview I call first with the call library function node the function to initialize, later I call inside a while loop the wait function like this
int waitAseconds (double seconds, short stop_waiting)
if(flag==1 || stop_waiting == 1)
flag = 1; //to detect the stop_waiting button
printf("flagAA =1 stop waiting = %d time = %d\n", stop_waiting, clock());
return flag;
else
SleepUS(seconds*1000000);
//a++;
printf("flag a= %d stop waiting = %d time = %d\n", flag, stop_waiting, clock());
return flag;
and when the program detects an interrupt, the function returns to labview the flag and stops the loop. Finally, it reads the values and close communications.
In this way, the prompt appears but after running the application for 10 or 20 minutes and also i checked that there is a time gap between the executions in the loop.
Thanks for your reply and your help,
Jaime

How do I Install or re-buy iPhoto for my Mac when the app can't lunch?
The App Store does not let me buy iPhoto from scratch nor update it. I used the original Applications Install DVD to re-install iPhoto, and the icon appeared but the app could not be used because iPhoto 2.1 is not compatible with the Mac operating system OS X (10.9.2)? I thried to update manually through apple support, and a notification of unauthorized licence did not let it happen. What is this? What happened with my iPhoto? What can I do to solve this and safe my photos? I'm willing to pay for it, but even the app store say that it can't becuase it was suppousely bought through another account? Please help!

Not launching is probablay not a software issue - it is probably a data issue
No - iPhoto 2 version 2.1 is not compatible with Mavericks - or pretty much anything else - you need to purchase iPhoto '11 version 9.5.x from the App store
