The problem about GPIB Wait

Dear all,
First, Thank you for your attention!!!
I have to use a network analyzer to perform a test for the return loss of antenna. For convenience, I have to use both port 1 and port 2 in order to test two samples together. Because I plan to use mechanical button to trigger the test, this may have problem to cause a crash when two requeust arise together.
May I know whether I can use the function GPIB wait to avoid it to happen?
THANK YOU VERY MUCH

If your two mechanical buttons are read by LV and your code has two separate loops to allow both tests to run independently, then you should have a look at the example called Semaphore using SubVIs. Using a semaphore you can have the first button grab the semaphore and the second button will wait until the semaphore is released to start the test.

Hello apple
I have the problem with my iPhone and my friends have this problem too.
My iPhone have the problem about calling and answer the call. When I use my iPhone to call I can't hear anything from my iPhone but the person that I call can answer it but when answer both of us can't hear anything and when I put my iPhone to my face the screen is still on and when I quit the phone application and open it again it will automatic call my recent call. And when my friends call me my iPhone didn't show anything even the missed call I'm only know that I missed the call from messages from carrier. Please check these problem I restored my iPhone for 4 time now in this week. I lived in Hatyai, Songkhla,Thailand and many people in my city have this problem.
Who have this problem??

Apple isnt here. this is a user based forum for technical questions. The solution is to restart, reset, and restore as new which is in the manual after that get it replaced for hard ware failure. if your within your one year warranty its replaced if it is out of the warranty then it is 199$

I've got the problem about sharing the screen

Hi, i bought iMac 21.5 (Late 2013), i'v upgraded it to the Mavericks. I've got the problem about sharing the display, i have thunderbolt to hdmi adapter and while i plug it to my TV, it doesn't work, it has no signal on TV, can someone help me ?? Thank Yo

Hello Gukakila
Start your troubleshooting with the article below. Try out the cable on a different tv or monitor to see if it shows up there. You may also need to reset the SMC and Parameter Ram.

The problem about x-fi elite pro's I/O conso

When i bought the x-fi elite pro,i used it on the AMD athlon64 3500+ ?ASUS ax800xt and GigaByte K8NSNXP-939 motherboard in windowsxp sp2 32bit.
After i installed it just as the quick start said,everything is fine and i like it very much.
I do think that creative had done a great job and it is the best reason to change the sb audigy2 ZS platinum pro.
But the problem comes when i change the hardware to amd AMD Athlon64 X2 4400+?Leadtek 7800GTX(single,not SLI)and ASUS A8N32-SLI motherboard.
After i changed the three things, i shut up to the older winxp pro sp2 32bit,it found a lot of newhardware,most of them are related to the nforce4 sli chipset,when it found x-fi,the system bring up blue screen and restart automaticly.
After the restart,i can startup in the system and change the settings of the x-fi(the hardware id has changed) ,and thus everything seems fine(the S750 works well),but the I/O console has no response, the blue led of the I/O console is dark.
Since then,i am in a nightmare.
I have tried a lot of ways in order to solve the problem, but it didn't work.first, i check the AD_Link carefully and everything is tight and fine,then i change the power splliter cable to another,i also plug the x-fi card into another slot and reinstall the operating system.
And now, i don't know how to solve the problem, Someone please help me.
plus,i use the newest motherboard bios 009,nforce4-sli chipset driver and 7800GTX drivers.
Eagerly for your advice.Message Edited by bravo on 0-5-2006 03:5 PM

The problem is actually about the power connector to the card (which powers the external box).
But of course is not since I forgotten to attach it
It is because the power connector is very tight, so when my friend helping me pulled out the connector, the connector?s plastic jack is also pulled out a half.
I don't notice it when I attach the power connector to it in my new computer, So the power connector can't really provide the power to the external box.
I hope someone can get some help from this thing.

The Problem about Monitoring Motion using PCI-7358 on LabVIEW Real Time Module

Hello everyone,
I have a problem about monitoring the position of an axis. First let me give some details about the motion controller system I’m using.
I’m using PCI-7358 as controller and MID-7654 as servo driver, and I’m controlling a Maxon DC Brushed motor. I want to check the dynamic performance of the actuator system in a real time environment so I created a LabVIEW function and implemented it on LabVIEW Real Time module.
My function loads a target position (Load Target Position.vi) and starts the motion. (Start.vi) then in a timed loop I read the instantaneous position using Read Position.vi. When I graphed the data taken from the Read Position.vi, I saw that same values are taken for 5 sequential loops. I checked the total time required by Read Position.vi to complete its task and it’s 0.1ms. I arranged the loop that acquires the data as to complete its one run in 1ms. But the data shows that 5 sequential loops read the same data?

Read Position.flx can execute much faster than 5 ms but as it reads a register that is updated every 5 ms on the board, it reads the same value multiple times.
To get around this problem there are two methods:
Buffered High-Speed-Capturing (HSC)
With buffered HSC the board stores a position value in it's onboard buffer each time a trigger occurrs on the axis' trigger input. HSC allows a trigger rate of about 2 kHz. That means, you can store a position value every 500 µs. Please refer to the HSC examples. You may have to look into the buffered breakpoint examples to learn how to use a buffer, as there doesn't seem to be a buffered HSC example available. Please note that you need an external trigger-signal (e. g. from a counter of a DAQ board). Please note that the amount of position data that you can acquire in a single shot is limited to about 16.000 values.
Buffered position measurement with additional plugin-board
If you don't have a device that allows you to generate a repetitive trigger signal as required in method 1.), you will have to use an additional board, e. g. a PCI-6601. This board provides four counter/timers. You could either use this board to generate the trigger signal or you could use it to do the position capturing itself. A PCI-6601 (or an M-Series board) provides can run a buffered position acquisition with a rate of several hundred kHz and with virtually no limitation to the amount of data to be stored. You could even route the encoder signals from your 7350 to the PCI-6601 by using an internal RTSI cable (no external wiring required).
I hope this helps,

The problem about settuping up the development Enviroment for OA

Hi, All
     I just began to learn the development of OA Framework, I met the problem of setting up the dev environment by using jdevelop 9i OA
extension.
     The following is steps of setting up the env by referrring to the "Oracle Application Framework Developer's guide".
     1, set the environment variable JDEV_USER_HOME to <jdeveloper dir>\jdevhome\jdev
     2. copy the DBC file from <EBS install dir>\visappl\fnd\11.5.0.\secure in EBS server to the local machine.
     3. create a tester user and assign it the responsibility "OA Framework ToolBox Turtorial" and "OA Framework ToolBox Turtorial
Labs" in EBS
     4. create a database connection. set the connection type as Oracle(JDBC), username and password as "Apps" and "Apps" , Set the
hostname and SID the same values as those specified in the DBC file. And the connection is created successfully.
     5. Then open the toolbox.jws (The sample code in the jdeveloper9i)
          i) select the tutorial.jpr , select Project > Project Setting -> Runtime Connectiong. setting the "DBC File Name" to the
DBC file path in local machine. setting the "user name" and password to EBS user I just created in step 3. Set the Application Short Name
to "AK" and Responsibility Key as "FWK_TBX_TUTORIAL".
          ii) right click tutorial.jpr. select "Edit Business Components Poject..." -> Connection . choose the Connection created in step 4.
     6. setting the same configuration for LabSolutions.jpr.
     7. After all these setting , then rebuild the toolbox.jws and run the project. It took a long time to display the test_fwktutorial.jsp and when I click the link in it. I wil get an error page. The Detail Info is the following:

The problem about MouseListener,MouseMotionListener

When I compile my program I face a problem with the compiled informatioin:
XYZApp.java:137: DisplayPanel should be declared abstract; it does not define mouseDragged(java.awt.event.MouseEvent) in DisplayPanel
class DisplayPanel extends JPanel implements MouseListener,MouseMotionListener
And the DisplayPanel class is below:
class DisplayPanel extends JPanel implements MouseListener,MouseMotionListener
DisplayPanel()
     {}//constructor
//Add or remove the mouse response
     public void PanelremoveMouseListener()
          removeMouseListener(this);

What is the problem?

When you post code, please use [code] and [/code] tags as described in Formatting Help on the message entry page. It makes it much easier to read and prevents accidental markup from array indices like [i].
Error messages are really cool; they'll generally do a real good job of telling you what's wrong. Learn to read them - it's essential you understand them if you want to improve as a programmer.

Should I get an iMac with all the problems about?

So, as my birthday is coming up I decided to get an iMac, however on Wednesday I read on Gizmodo about the yellow screen debacle, so after doing some research on the matter I'm not sure what to get any more.
I decided (Before I read this on Giz) to get a 21.5" iMac.
So I have a few questions about it.
1: Does the 21.5" iMac's screen flicker and blackout like the 27", it's very hard to find info about it as it seems it only affects 27", but is that because it doesn't effect 21.5" or because not many people bought the 21.5" iMac
2: Just how bad is this 'yellowing', I've looked at various photos of it and can hardly see any problem, does anyone have a really bad screen with the bottom of the screen being strongly yellow tinted?
3: Should I just skip all these problems and get a Macbook?
Please help me decide!

You have done your research on the new iMacs so you already know the answers to your questions. It's difficult to come to a consensus though because some report problems and some report they have no problems. It's your birthday... in my honest opinion, go for it.
Post back when you have your machine as to your findings on your machine. That's the one that matters.
Sorry if I am sounding a little tired of this but many people have asked the same question and many have provided the same answers. If you are very conservative you might want to wait and see, but if you don't want to postpone your birthday, go ahead; your iMac may be fine and if not, Apple will make it right. Do buy AppleCare.

The problem about multi-thread in java application

i have problem with the multi-thread in java application, i don't know how to stop and restart a thread safely, because the function thread.stop(),thread.suspend() are both deprecated.
now what i can only do is making the thread check a flag(true or false) to determine whether to start or to stop, but i think this thread will always be in the memory and maybe it will lower the performance of the system, as the program i am developping is working under realtime enviorement.
please help me about it. thanks !

hi,
you can stop a thread by exiting it's run()-method which in terms can be done by checking the interrupted-flag:
public void run(){
while(interrupted()){ //if the thread consists of a loop
or
public void run(){
if(interrupted())return;
if(interrupted())return;
or by the use of the return-statement anywhere withing the run-method. Afterwards, that is when the thread is no longer needed, you clear all the references to the specific thread object by setting them to null:
Thread t;
... //working
t.interrupt(); //interrupting
while(t.isAlive()){
Thread.yield(); //wait till thread t has stopped
t=null;

The problem about integrate Portal and R/3

Hi everyone :
   We want to achieve that our vendor can query R/3 report via our Portal. I had done SSO configuration.
   But we had about 500 vendors, it is impossible that we create 500 R/3 users for our vendors, because the cost is too much .
   And there is another problem, vendor who had the authorization to query report can query the other vendor's data at same time. But we expect that certain vendor can query his data only.
   I think this is a general problem when integrate Portal and R/3, BW .
   Is there somebody had solved this problem or give any advice?
   Any discuss is welcome.
Best Regards,
Jianguo Chen

Hi,
I would say: get in contact with your SAP account manager anc check which options SAP can offer you...
Normally every user using a R/3 system has to have a valid user license in that system. Expecially when you want to access control to data on user (vendor) level you nedd to identifiy the user clearly and uniquely which by standard means you need a user for every vendor.

The problem about the signal of JNI

Hello,
When the system (it creates by the C language) created here is operated on Solaris and javaVM is operated using a JNI, the phenomenon which the core file outputs within the JIT compiler of java (libsunwjit.so) has occurred.
Although it had generated twice until now, since it had collided with the signal which the signal has generated in one of the another threads, and it uses internally by JavaVM from the contents of a core file when it generated first, it had generated.
However, although the core file was investigated when it generated at the 2nd times, there was no trace that another thread generated the signal.
Is there any case where collide with the signal currently used by JavaVM, and also a signal is generated in a JIT compiler?
What thing has an obstacle used as the factor which a JIT compiler makes have generated the signal in the past again?
Please give me the reply to the above-mentioned question for a cause elucidation.
As appending data, the contents which referred to the core file are described below.

The Problem about clearing the system cache

Hi, there!
I'm trying to draw a lot of image in iPhone programming.
I used [UIImage imageNamed].
but it doesn't clear immediately the system cache.
At last it occurs the out of memory.
So I thought using imageWithContentsOfFile, but it works very slowly.
Does anybody know how to clear the system cache?

The problem about 2g/3G toggle

HI, am using iPhone 5s. I upgraded to ios8 couple of days back. I have a problem in switching my data plans to 2g and 3g. Mostly I use 2g and I don't have LTE in my area. I would like to know, there's any option to restore ios7.1.2.

The option is controlled by your carrier. Talk to them about it. If 3G and LTE coverage is poor in your area with your carrier, then switch to one that provides decent coverage.
Many carriers are disabling the switch because they are in the process of shutting down their 2G (EDGE) networks entirely.
