Can I get better time resolution than 1ms in labview?
Hello,
I am trying to generate an external waveform which requires timing to be in the microsecond range, I was trying to use the wait function to define the timing dt but found that I could not get below 1 ms. I tried to specify timing in the microsecod range by overloading the wait function with a float (0.200) to represent 200 us but found behavior to be erratic. Again, I am trying to create a waveform for extenal hardware which does not support buffering and requires software to drive.
Thanks!

"I am trying to create a waveform for extenal hardware which does not support buffering and requires software to drive."
Sorry but that simply can not be done in a Windows environment due to the limitaions of the OS (1KHz was "way-fast" when WIndows replaced DOS).
It can be done in a Real-Time OS like Pharlap for example.
Attempts to deterministically perform any operation at a rate faster than 1KHz in a non-deterministic OS can be best described as an "exercise in futility."
Trying to help,
Ben
Note to Waldermar:
Timed loops can perform rather well at 1KHz or even better if you have a hardware clock available.

Can you get free trial more than 1 time
Can you get free trials more than on time on the same computer cause i need dreamweaver but cant pay for it i use at school but dont have it on my computer yet just the trial
This page says that you cannot restart a trial, you can only install onto a different machine:

You can try contacting Adobe support ( http://www.adobe.com/support/contact/ ), and maybe they will have some other work around. You should also check with your school, they may have a student or education price that is much much less than the retail price of Dreamweaver. -
How can I get my Time Capsule to show up in finder?
How can I get my Time Capsule to show up in finder?
An alternate, and simpler method for most users is to open any Finder window, then look for the Time Capsule icon under the Shared heading on the left side of the window.
When you click on the Time Capsule icon, a folder......named "Data", unless you have changed the name of the drive.....will appear to the right.
Double-click "Data" to mount the Time Capsule drive on the desktop, where you can now drag/drop or copy/paste data to the drive.
If the Time Capsule does not appear under the Shared heading when you open a Finder window......then you are likely using the Yosemite operating system on your Mac, and it will take some work to find it.
In that case, Niel's method might be the better way to go. -

How can i get current time of a given timezone
how can i get current time of a given timezone
for example: Asia/Hong_Kong
my code is like this, but the result is not correct.
what's wrong?
import java.util.*;
public class test {
public static void main(String[] args){
String s = "Asia/Hong_Kong";
String tempS = "";
TimeZone myTime = new SimpleTimeZone(s);
//TimeZone myTime = TimeZone.getTimeZone(s);
Calendar myCal = new GregorianCalendar(myTime);
tempS = myCal.get(Calendar.YEAR)+"-"+
(myCal.get(Calendar.MONTH)+"-"+
myCal.get(Calendar.DATE)+" "+
(myCal.get(Calendar.HOUR)+":"+
myCal.get(Calendar.MINUTE)+":"+
myCal.get(Calendar.SECOND);
System.out.println(tempS);
output is : 2001-7-15 11:16:48
but the correct time should be: 2001-8-16 7:17:48
the correct time should be 2001-8-16Certain indexes in the Calendar API start at 0 rather then 1, so, when you get the value, you may want to increment.
I'm not sure why the time is incorrect. You may want to call getAvailableIDs() and make sure that the desired TimeZone ID is supported by your version. I doubt that Sun would have incorrect support for the time zone, but it may not be included, or perhaps it is included with a diffrent ID. You can always create your own time zone as well, by passing the String offset to getTimeZone(), the offset being how many hours beyond or before GMT. Hopefully this helps. -
Can I get Quick time video on iPad 2? Specifically, when I receive an email with quicktime on it, it will not play on the iPad.
Hello. I have AV player hd. When I touch and hold the Quicktime icon that is in a received mail message, a prompt comes up "Open in AVPlayerHD". I click on that and a black screen opens up with the following on it:
1--A red line at the top with a short white slider button on the right hand side. There is a time listed at each end of the red line that says 00:00
2--On the left hand side of the screen, near the middle, there are 4 icons, a colored 'x', a dialogue icon, a circular arrow and an 'i' in a circle.
3--On the right hand side there is a + and a - sign with '1.00x' in the middle of the two.
4--At the bottom of the black screen is a play icon plus forward and fast forward icons.
When I press the play icon it changes to a stop icon.
So, even though I have AV player I cannot play this Quicktime slideshow.
Any help would be appreciated. Thanks. -
Can i get the time capsule to automatically back up my file from my Mac Book Air but have certain files which are only stored on the time capsule and not the computer? Then can i access these files only on the time capsule without connecting it?

You can, but how are you going to back up those other files? When (not if) your Time Capsule fails, you risk losing them. See #Q3 in Using Time Machine with a Time Capsule for details.
Then can i access these files only on the time capsule without connecting it?
Not sure what you mean. You have to connect a computer, either via Ethernet cable or wirelessly, to read or write to the disk. -

How can i get current time in different TimeZone
Hi alls,
How can i get current time in different TimeZone.
I've tried
final Calendar calendar = Calendar.getInstance(GMT0_TIME_ZONE);
final Date date = calendar.getTime();
but it returns current time in my time zone not in GMT0a simple way would be:Sometimes gets you the right result (not during daylight saving), but always the wrong way.
I would strongly recommend getting into the habit of handling Dates correctly. A Date is a universal instant in time - the number of milliseconds since midnight GMT on 1 January 1970. That instant corresponds to various dates and times, depending on your time zone and the effect of daylight saving. You make that conversion of a universal instant to a localized date/time using Calendar and DateFormat. -

How can I get my time machine to allow me to recover files again?
After upgrading MBA to OS X, the time machine still backs up the files; but, I'm not able to navigate within the time machine or select any folders or files for restore.
I've searched and can not find a solution to the problem that's being encountered.Yeap that all makes sense now.
Do you only have the current backup showing in the TM display?? Won't it fill in the rest?
Over wireless are you waiting for the indexing to finish.. ??
Previous backup may not show for a couple of hours.
Long short of it.. Mavericks version of TM is a pain.
Sometimes it is easier to completely ignore the TM backup and do the restore manually.
I have posted the details here. See if this helps.
