This is how the X-Fi soundcard should work. Ican do it with 2 soundcar
Hi There. For?some new X-Fi drivers and software I have a suggestion that would be awsome. First though, let me explain what I'm doing. I have 2 souncards. the first is an X-Fi Extreme music which is set as the primary soundcard. This souncard is patched into the inputs of an inca88, 8 input 8 output Studio card. the inca88 is running with Sonar 6 PE (recording software) which allows me to apply?DXI and VST effects to all the channels, create custom routing of sound from each channel to the subwoofer and even apply a Compressor/limiter to prevent overload. I use multiband parametric EQs for each channel and can set exact crossover slopes to all speaker outputs. I use it for gaming, HTPC, and as a home recording studio and it has very minimal hit on my CPU. The XP software for the X-Fi has a very limited audio creation mode which allows some very basic effects to be used with just an X-Fi. However the ability to use of DXIs and VST within the creative Audio Creation mode would mean that third party effects can be used to produce truly amazing results. This stuff is entirely possible to do so if you want the above functionality then ask Creative for it. Regards,?Thunderknob? :?)?
We're talking about Creative here who can barely get a decent driver out after 6 months... :/

I am attempting to upgrade from Adobe Premier Elements 9 to Adobe Premier Elements 13 after using 13's trial version for a few weeks. I am unable to find where and how to do this without losing the project I have been working on. Please help?
Vere Clarke
Premiere Elements 9.0/9.0.1 and Premiere Elements 13 are standalone products.
So, you can have both on the same computer, but only open one for your work.
The classical recommendation is to finish a project in the version in which it was created since there
is no guarantee that a project from an earlier version will open in the later version. Probably will, but
no guarantees. And, when you do explore this, do it from a copy of the earlier version project. Once you
take the earlier version project into a later version one, you cannot go back to edit the later version edited
project in the earlier version program.
If you have both versions (9 and 13) on the same computer and you have not moved, deleted, renamed any of the version 9's files/folders,
right click the saved closed Premiere Elements 9.0/9.0.1 project file, select Open With, and then Adobe Premiere Elements 13.
(Your 9.0/9.0.1 saved closed project file should be found in Libraries/Documents/Adobe/Premiere Elements/9.0.)
Please review and consider. If any questions or need clarification, please do not hesitate to let me know.
Thank you.

In the Firefox browser, when i click button in ADF page, then popup the OAF page in iframe tag,and then when i click the PPR bean in OAF page, then Firefox browser reload to ADF page. This is not the right response,browser should not reload the ADF page.It should stays in OAF page or goto another OAF page. and in other browser such ad IE,We get the right response.
hello, normally such issues are caused by a firewall/security software which doesn't recognize & therefore blocks new firefox versions. please remove all program rules for firefox from your firewall and let it detect the new version of the browser again.

How the IVI New Session.vi works with the ivi.ini?
Hi,all
Does anyone know how the IVI New Session.vi works with the configuration file ivi.ini?
And when the ivi application running, how the ivi calss driver refers to the right specific instrument drivers without changeing the program?
Thanks,
njzhw
人的生命是有限的，但知识是无限的！
南京众知维测试技术有限公司Which VI or function are you referring to? There is neither an "IVI New Session.vi", nor a corresponding "Ivi_NewSession" function in C.
The Ivi Class Drivers determine which specific driver to use at run-time, by looking up the resource descriptor (a Logical Name, or Virtual Instrument) and determining the associated Instrument Driver. That configuration information is settable by the user through MAX (Measurement and Automation Explorer).

Ok I have an fully upgraded iPad 2 and the volume button don't work but it do with headphones can someone help. I try to go to settings and the volume won't go up there either I have the home button gesture and still the same. I try resting my iPad and nothing no sound work unless I have my headphones in. Do anybody know how to fix this
Did you try rebooting the iPad? You will need to have some battery power for this.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

I have a VGA adapter and an iPad2. Tried projecting my iPad2 to projector using the VGA but doesn't work. Tried it with friend's iPad1 and it works. Why?? Pls help.
Yup - nothing happens. I then took the same VGA cable and plugged it into my friend's iPad1 and it worked perfectly when she opened Keynote. My understanding is that the iPad2 mirrors the entire screen, so no need to go into any specific application in order to project to the screen, right? Do I need to download any specific app or change any settings in order to be able to project the screen using VGA?
Sorry - novice at this. Not very tech minded either... -
Is this roughly how the labVIEW Execution Systems work?
I've not taken a class in OS design, so I don't know the strategies used to implement multitasking, preemptive or cooperative. The description below is a rough guess.
LabVIEW compiles Vis to execute within its own multitasking execution environment. This execution environment is composed of 6 execution systems. Each execution system has 5 priority queues (say priorities 0->4). Vis are compiled to one or more tasks which are posted for execution in these queues.
An execution system may either have multiple threads assigned to execute tasks from each priority queue, or may have a single thread executing all tasks from all priority queues. The thread priorities associated with a multithreaded execution system are assigned according to the queue that they service. There are therefore 5 available thread priority levels, one for each of the 5 priority level queues.
In addition to the execution queues, there are additional queues that are associated with tasks suspended in various wait states. (I don't know whether there are also threads associated with these queues. It seems there is.)
According to app. note 114, the default execution environment provides 1 execution system with 1 thread having a priority level of 1, and 5 execution systems with 10 prioritized threads, 2 threads per priority queue. NI has titled the single threaded execution system "user interface" and also given names to the other 5. Here they will be called either "user interface" or "other".
The "user interface" system is responsible for all GUI actions. It monitors the keyboard and mouse, as well as drawing the controls. It is also used to execute non-thread-safe tasks; tasks whose shared objects are not thread mutex protected.
Vis are composed of a front panel and diagram. The front panel provides an interface between the vi diagram, the user, and the calling vi. The diagram provides programmatic data flow between various nodes and is compiled into one or more machine coded tasks. In addition to it own tasks, a diagram may also call other vis. A vi that calls another vi does not actually programmatically branch to that vi. Rather, in most cases the call to another vi posts the tasks associated with the subvi to the back of one of the labVIEW execution system�s queues.
If a vi is non-reentrant, its tasks cannot run simultaneously on multiple threads. This implies a mutex like construction around the vi call to insure only one execution system is executing the vi. It doesn�t really matter where or how this happens, but somehow labVIEW has to protect an asynchronous vi from simultaneous execution, somehow that has to be performed without blocking an execution queue, and somehow a mutex suspended vi has to be returned to the execution queue when the mutex is freed. I assume this to be a strictly labVIEW mutex and does not involve the OS. If a vi is reentrant, it can be posted/ran multiple times simultaneously. If a vi is a subroutine, its task (I think there is always only one) will be posted to the front of the caller's queue rather than at the back of the queue (It actually probably never gets posted but is simply mutex tested at the call.) A reentrant-subroutine vi may be directly linked to its caller since it has no restrictions. (Whether in fact labVIEW does this, I don�t know. In any event, it would seem in general vis that can be identified as reentrant should be specified as such to avoid the overhead of mutexing. This would include vis that wrap reentrant dll calls.)
The execution queue to which a vi's tasks are posted depends upon the vi execution settings and the caller's execution priority. If the caller's execution priority is less than or equal the callee's execution settings, then the callee's tasks are posted to the back of the callee's specified execution queue. If the caller's execution priority is greater than the callee's specifications, then the callee's tasks are posted to the back of the caller's queue. Under most conditions, the vi execution setting is set to "same as caller" in which case the callee�s tasks are always posted to the back of the caller's execution queue. This applies to cases where two vis are set to run either in the other execution systems or two vis are set to run in the user interface execution system. (It�s not clear what happens when one vi is in the �user interface� system and the other is not. If the rule is followed by thread priority, any background tasks in the �other� systems will be moved to the user interface system. Normal task in the �other� systems called by a vi in the �user interface� system will execute in their own systems and vice versa. And �user interface� vis will execute in the caller�s �other� system if the caller has a priority greater than normal.)
Additionally, certain nodes must execute in the "user interface" execution system because their operations are not thread-safe. While the above generally specifies where a task will begin and end execution, a non-thread safe node can move a task to the �user interface� system. The task will continue to execute there until some unspecified event moves it back to its original execution system. Note, other task associated to the vi will be unaffected and will continue to execute in the original system.
Normally, tasks associated with a diagram run in one of the �other� execution systems. The tasks associated with drawing the front panel and monitoring user input always execute in the user interface execution system. Changes made by a diagram to it own front panel are buffered (the diagram has its own copy of the data, the front panel has its own copy of the data, and there seems to be some kind of exchange buffer that is mutexed), and the front panel update is posted as a task to the user interface execution system. Front panel objects also have the advanced option of being updated sequentially; presumably this means the diagram task that modifies the front panel will be moved to the user interface execution system as well. What this does to the data exchanged configuration between the front panel and diagram is unclear as presumably both the front panel and diagram are executing in the same thread and the mutex and buffer would seem to be redundant. While the above is true for a control value it is not clear whether this is also true for the control properties. Since a referenced property node can only occur on the local diagram, it is not clear it forces the local diagram to execute in the user interface system or whether they too are buffered and mutexed with the front panel.
If I were to hazard a guess, I would say that only the control values are buffered and mutexed. The control properties belong exclusively to the front panel and any changes made to them require execution in the �user interface� system. If diagram merely reads them, it probably doesn�t suffer a context switch.
Other vis can also modify the data structure defining the control appearance and values remotely using un-reference property nodes. These nodes are required to run in the user interface system because the operation is not thread-safe and apparently the diagram-front-panel mutex is specifically between the user interface execution system and the local diagram thread. Relative to the local diagram, remote changes by other vis would appear to be user entries.
It is not clear how front panels work with reentrant vis. Apparently every instance gets its own copy of the front panel values. If all front panel data structures were unique to an instance, and if I could get a vi reference to an instance of a reentrant vi, I could open multiple front panels, each displaying its own unique data. It might be handy, sort of like opening multiple Word documents, but I don�t think that it�s available.
A note: It is said that the front panel data is not loaded unless the front panel is opened. Obviously the attributes required to draw an object are not required, nor the buffer that interfaces with the user. This rule doesn�t apply though that if property references are made to front panel objects, and/or local variables are used. In those cases at least part of the front panel data has to be present. Furthermore, since all data is available via a control reference, if used, the control�s entire data structure must be present.
I use the vi server but haven�t really explored it yet, nor vi reference nodes, but obviously they too make modifications to unique data structures and hence are not thread-safe. And in general, any node that accesses a shared object is required to run in the user interface thread to protect the data associated with the object. LabVIEW, does not generally create OS level thread mutexes to protect objects probably because it becomes to cumbersome... Only a guess...
Considering the extra overhead of dealing with preemptive threading, I�m wondering if my well-tuned single threaded application in LV4.1 won�t out perform my well-tuned multithreaded application in LV6.0, given a single processor environment�
Please modify those parts that require it.
Thanks�
Kind Regards,
EricBen,
There are two types of memory which would be of concern. There is temporary and persistent. Generally, if a reentrant vi has persistent memory requirements, then it is being used specifically to retain those values at every instance. More generally, reentrant code requires no persistent memory. It is passed all the information it needs to perform its function, and nothing is retained. For this type of reentrant vi, memory concern to which you refer could become important if the vis are using several MBytes of temporary storage for intermediate results. In that case, as you could have several copies executing at once, your temporary storage requirements have multiplied by the number of simultaneous copies executing. Your max memory use is going to rise, and as labview allocates memory rather independently and freely, the memory use of making them reentrant might be a bit of a surprise.
On the other hand, the whole idea of preemtive threading is to give those tasks which require execution in a timely fashion the ability to do so regardless of what other tasks might be doing. We are, after all, suffering the computational overhead of multithreading to accomplish this. If memory requirements are going to defeat the original objective, then we really are traversing a circle.
Anyway, as Greg has advised, threads are supposed to be used judiciously. It isn't as though your going to have all 51 threads up at the same time. In general I think, overall coding stategy should be to minimize the number of threads while protecting those tasks that absolutely require timely execution.
In that sense, it would have been nice if NI had retained two single threaded systems, one for the GUI and one for the GUI interface diagrams. I've noticed that control drawing is somewhat slower under LV6.0 than LV4.1. I cannot, for example, make a spreadsheet scroll smoothly anymore, even using buffered graphics. This makes me wonder how many of my open front panel diagrams are actually running on the GUI thread.
And, I wonder if threads go to sleep when not in use, for example, on a wait, or wait multiple node. My high priority thread doesn't do a lot of work, but the work that it does is critical. I don't know what it's doing the rest of the time. From some of Greg's comments, my impression is it in some kind of idle mode: waking up and sleeping, waking up and sleeping,..., waking up, doing something and sleeping... etc. I suppose I should try to test this.
Anyway that's all an aside...
With regard to memory, your right, there are no free lunches... Thanks for reminding me. If I try this, I might be dismayed by the additional memory use, but I won't be shocked.
Kind Regards,
Eric -
I just loaded Firefox onto my laptop. I set up the the sync add on and had no errors. When I hit sync now I get "Sync encountered an error while syncing: Firefox sync server maintenance is underway, syncing will resume automatically." I have gotten this message for the last 10 hours. Should I wait or is there an issue with my setup? I checked the Mozilla sync server status and it listed no issues.
There was a server out last week. see below. now everything works great. thanks for the follow up.

unable to launch firefox after I upgraded firefox
I see you are using a PPC Mac with OSX 10.5.8.
Either you can use the last release from Mozilla worked on PPC which is 3.6.*.
The current 3.6.22 is at http://www.mozilla.org/en-US/firefox/all-older.html
Or use a third-party build from http://tenfourfox.blogspot.com/2011/08/601-now-available.html
As of Firefox 4.0 and newer a '''Intel''' Mac and OSX 10.5+ is required. -
How Session based web Application should work even after session expiry??
I am looking for an experts opinion that how could I develop an application that should work after the expiry of web session too in the same way as it works in web session.
How the session should be activated.
As I understood, what if I store all the required information in xml and then on unlock session reload all the information from XML.
Am I right or is there any other better way to do using servlets.
Basically I need to implement Lock and UnLock mechanism in an application.
ThanksI'm not sure I understand your question. But since no one answered this yet, here is my idea:
If the user's session expires, any unsaved data is lost. The user should expect this.
If do need to save any data, normally you store it it a database table with the user's ID so you can retrieve it. Two free databases are Oracle Lite and MySql. However, this will take quite a bit of time to learn if you are not already familiar with databases. Storing it in a database and retrieving it is much much faster than storing it in a file. -
How the getNetworkInterfaces() of NetworkInterface class works
Hi,
I would like to know how the method getNetworkInterfaces() method in the NetworkInterface class works. Sometimes I get a cached data on the interfaces, sometimes I get an empty Enumeration getting returned. Does this method not get the refreshed values of the NetworkInterfaces??
Thanks
SwamiI would like to know how the method getNetworkInterfaces() method in the NetworkInterface class works.
Enumeration<NetworkInterface> networkInterfaces = NetworkInterface.getNetworkInterfaces();
List<InterfaceAddress> interfaces = new Vector<InterfaceAddress>(1,1);
while(networkInterfaces.hasMoreElements())
interfaces.addAll(networkInterfaces.nextElement().getInterfaceAddresses());
}This code will extract all the interfaces present on your network and add then in a Vector.
