Reset BufferedReader pointer back to zero
How do I reset the position of a BufferedReader object back to 0? For example, I want to do something with the BufferedReader object, namley use the read() method, and then once I do that, I would like to reset the pointer back to index 0 (or the beginning of my file).
I am using BufferedReader to open a file.
I tried using the reset() method, but that does not seem to work. I also used the skip() method, hoping to "skip" backwards, however that is not possible because you can only skip forward.
Thanks in advance!
Thanks for your help.
Yes, originally I got an IOException, that I simply caught.
Also, thanks for pointing out that the reset() method does not do what I want, meaning reset it back to the beggining of the file. So I have gotten absolutely nowhere.
Do you know how I could reset my marker back to the beginning of the file? What I actually want is to go back 9 characters in the file after I have made the call read().
Once again, thanks.

I play Subway Surfer on my other account on my iPad so a friend of mine cheated and got a very high score now I want to reset this score back to zero so is there a way to do that or I have to delete the game and create a new apple ID for my iPad
Hi Nick,
If you have an X Series or 2nd Generation cDAQ chassis (basically any cDAQ chassis except for the 9172 or 916x sleeves) then you can implement:
1,2,3,4,5,6,7,8,9,10,(reset),1,2,3,4,5,6,7,8,9,10,(reset),1,2...
You would have to configure an Edge Count Task, set the initial value to 232 - 6 (such that the 6th count causes the counter to rollover, which generates a pulse on the counter output), and enable the count reset using your external signal:
The count reset isn't currently available for other DAQ devices, but I believe it should be available on M Series (62xx) and TIO (660x, 6624) with a future driver release (some time in 2012).
If you don't have an X Series (or gen II cDAQ), don't despair. On other hardware, you can get close to the previous behavior with a counter output task, with the exception that the "reset" signal would only be detected after the 2nd tick after your pulse is output. Also, the reset signal would have to occur at the beginning to arm the counter the first time.
Or, you can get the 3rd behavior that you asked for by doing a continuous counter output task with the external signal as the source of the timebase ticks. For example:
1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,9
In toggle mode (default):
6 ticks of initial delay, 2 ticks high, 7 ticks low, 2 ticks high, 7 ticks low, ... etc.
In pulse mode:
6 ticks of initial delay, 9 ticks high, 9 ticks low, 9 ticks high, 9 ticks low, ... etc.
See here for an overview of the difference of the two modes. Basically, pulse mode will emit a short pulse when TC is reached, and toggle mode will toggle the state of the counter. You can't have less than 2 ticks as a high time, low time, or initial delay.

Somehow, my Referer Header settings got set to 0 (zero). Because of this, I'm getting an error message on certain sites. I found out that I could reset it to 1 (one) or 2 (two) if I browsed to about:config and typed in the new value, but it doesn't seem to be working. I'm not sure how to "save" this setting, and ever time I refresh the about:config page the setting goes back to zero. Plus, I'm still getting the error messages on the sites I was having trouble with.

Unable to reset 831 router back to default settings
I need help with setting up my cisco 831 sdm k9 router. It was up running just fine but I ran the write-erase command to start over, little did I know that resting back to complete factory defaults did not work. The router did not go back to as if it where when I recieved it and plugged it in and followed the steps with using SDM.
Does anyone know how to set it back up so that I can configure it?
I have gone through the steps as listed at in the (reset to for mainline 12.3) to reset the router back to factory defaults and still no luck. All I need is to get the router reset back to how it was right out of the box so I can re-configure it.

I have a iPhone 5. In usage, it says i have 2.1 gigs used because of photos and camera. I have deleted all my photos via iPhoto and now reset the phone back to factory settings in order to try to solve this problem, to no avail. Both iTunes and the phone say that 2.1 gigs are being used, even though the phone now has nothing on it. What is going on?
Yeah it works fine over wifi the problem is when I try to use it over my 3G. It's really stressing me out now.

My iphone 4s is no longer detecting wifi since the IOS8 updates came out. I've restarted, rest the networks, reset the phone back to factory settings, and even tried the freezer trick. It is STILL not detecting ANY wifi networks. HELP!!! I cannot afford to go over my data and I use wifi at home and work... I believe the updates have caused the issue, because it was working fine before the second update released (I hadn't put the first one one until I noticed it had stopped working, and by then the second IOS8 version had came out). They need to do a third update to fix this issue.
If it's grayed out:
Reset Network Settings - if that doesn't fix it, then Backup and Restore AS A NEW DEVICE.
If it's still grayed out, unfortunately that means your Wi-Fi antenna quit, and it needs service. -
I had to completely reset my phone back to "new" at the Apple Store and the Genius told me that my PhotoStreams would download automatically back to my iPhone after the reset. They have not. Are they lost forever?
Have you logged into iCloud on the phone? If not they won't be there, also just to let you know photo stream doesn't keep your photos forever anyway. It will keep up to 1000 photo's after that it will delete the oldest photo there, it will also delete any photo that is 30 days old.

How to reset buffer pointer for analog output generation?
I am doing a finite analog output generation on a USB-6216
Sequence of events:
DAQmx Create Task
DAQmx Timing (finite samples, 1000Hz)
Use DAQmx timing property SampQuantamples per channel to set buffer size
Write buffer with DAQmx Write
Repeat
DAQmx Start Task
DAQmx Wait until done
DAQmx Stop Task
Until finished
DAQmx Clear Task
I get a full waveform output on the first iteration of the loop. On subsequent iterations I get only a small section of the waveform, but no error. It seems that it is regenerating the waveform, because when I switch off regeneration I get an error at Start Task, but before it can regenerate all the data Wait Until Done.vi decides that the generation is done and exits, stopping the generation.
I have done this with a PCI device and it works fine; every call to Start Task generates the whole waveform again.
OK, so it looks like after every waveform generation completes I need to reset the pointer to the start of the buffer, so that the Wait Until Done vi does not think the generation is done. Or - maybe there is a way to reset the "Generation Done" state?
I'm sure there's an easy way to do this....?Hi CDancer,
Many thanks for contacting National Instruments. If I can start by giving some general advice, it would be well worth posting your actual VI. This helps others on this forum in helping you with your application.
From the sounds of things, you want to do continuous analog output generation. I have had a look at the examples that come with LabVIEW and I think you should look at the one below.
I would have a look at some of the DAQmx examples that come installed with LabVIEW. The following example would be particularly relevant I feel
Cont Gen Voltage Wfm-Int Clk-non Regeneration.vi
Please let me know how you get on.
Many thanks,

I've been working in a LiveType doc and I cannot get the in point to register zero. I don't have any tracks (as far as I can see) that are taking up space at the beginning -- the first track is flush left against the in point marker.
Any suggestions regarding what might have gotten 'stuck' into place that's causing my in point to start at 54;12?
Thanks.Somewhere on your hard drive is a file called livetype.plist. Should be in a Library. Spotlight will find it, may take some variations.
Trash it.

Hello,
This is probably a mundane question but I am wondering what is the most efficient method to reset a Point.
1: Allocate a new Point
myPoint = new Point();
2: Set the point properties manually
myPoint.x = 0;
myPoint.y = 0;
3: Normalize its length
myPoint.normalize(0)
Any thoughts??
PierreHi,
That is also my pick, but it is a pretty annoying thing to code for each reset. This is where a pre compiler and macro definition would be so usefull. I guess this is old school coding by today standard...who cares about performances.

Reset ASA 5510 back to MFG Settings - Please help??
A network engineer was in the middle of setting up a customer ASA 5510 Firewall and left. We don't know the IP/UN/PW.
Is there a way to hard reset the firewall back to manufacture settings?
Thanks in advance.Hi,
The easiest thing would be to do a password recovery, as described here:
http://www.cisco.com/en/US/docs/security/asa/asa71/configuration/guide/trouble.html#wp1058131
Then you can simply reset the password and carry on where he left off.

Open the hard drive by double clicking its icon on the desktop (assuming you have these turned on to show). Double click the Users folder. Is there more than one account there? Is your original account still there? -
How do I reset color profile back to original?
I was trying to make my screen on my PowerBook G4 brighter.
I instead made the calibration of the colors all wrong.
How do I reset the colors back to the original settings?
Anyone know how to make the screen brighter than what the maximum that the F2 key can do?
I am on Tiger v. 10.4.2
My photos, background, and every window has all the wrong colors. AHH.Try first this is; Make sure "show profiles for this display only is NOT checked". If it was you should now have some more choices. Maybe one will work for you.
OPTION 2: Start wih the profile you messed up, select it and click "calibrate" CHECK he expert mode button and follow the directions. It's pretty straight forward, you don't need to be an expert to use it. Take your time and you will be able to calibrate your monitor.
Good Luck,

After IOS6 upgrade game centre says my nick name already in use. has reset some games back to beginning, how do i fix
I've had almost every issue you've had. Finally on Friday the screen blacked out. It was obviously still charged, since I could hear the message ring, but when I tried to light up the display it didn't light so I was unable to get to it unless I removed the battery. Then, as soon as the display timed out, I couldn't get it lit up again without removing battery. I had the same slow movements throughout the display as well as slow text messaging. Every issue you had other than the alarm clock (that always worked well).
I took it in yesterday and, after over an hour spent there with a 'professional', I still had no answers. He told me to come home and copy everything from my sd card to my computer, then re-format my card. Well, my phone didn't even recognize that I had an sd card installed!! Nor did my computer!
So then I got to experimenting...I removed the card and viola!!!!!! The phone worked GREAT! It's never worked so fast! I then installed my husbands sd card to see if it was my phone's card reader or my card. Turns out that the phone still worked great with his card installed and it did recognize his card in my phone. So, my conclusion is that I need a new card. I couldn't believe the difference in speed of everything! It's like a brand new phone!
As for the hard reset...I did that over the weekend, before I could get to a verizon store. It didn't work at all.
I'd say, do the same thing I did and see if that works. Can't hurt!!! Please keep me posted. I'd like to see what you find out
Good Luck!!!! -
Battery Problem (Charging but returns back to zero percent then back to normal)
I'm kinda frustrated about my macbook pro, I seriously want this to get fixed. My MBP is 2 1/2 years Last week My mbp shut downed by itself then I figured out that the problem was the battery so I replaced it then bought a new one. I bought a replacement battery not in the apple store but I bought it online(somewhere cheap).
so now the big problem was after installing the new battery my mbp is charging but it returns back to zero percent then back to normal, so I can't pull out the charger from my computer because it will shut down.
please help me.
