Is there a performance loss or gain when enabling 'make available through property nodes' in class accessor?

As the topic states, I'm pondering if there is a performance hit (or gain?) by making class accessor available through property node?
Specifically, I wonder if the 'class accessor property node' is somehow different than 'normal' property nodes, which I tend to avoid as best I can due to how they often involve the GUI thread and are often detrimental to performance.
And since the follow up question to any answer would be to ask if including error handling terminals changes the answer?
-People who write LVOOP on a semi-regular basis or more, is there a concensus on when/if you use the property node option? Is it preferred as a default almost? Is it affected by whether the accessor is dynamic or static?
Thanks!

As far as I know, there is no difference between a subVI call and a property call and they should behave identically behind the scenes. There shouldn't be a forced call in the UI thread, because these don't deal with UI elements. It's simply a different syntax, so it should be the same for DD. I have seen some complaints about performance issues and/or bugs in earlier versions, but I don't remember if there was anything concrete. You can search on LAVA.
Likewise, I don't think the error I/O itself causes delays, but both the serialization of the calls and having case structures acting on those errors can. AQ had some posts on that and he dislikes both. Personally, I tend to like the readability, particularly for serialized calls. Note that some people don't like accessors (at least public ones) as a concept, suggesting that having writers for individual fields leads to all kinds of troubles, and that it's generally better to have specific functions with the relevant inputs.

How much performance do I gain by enable MAT

Hi
I must try to ask you guys before am try to enable MAT
I have never entered the bios before so am a little scared that I will f-up the system.
Do anybody here at this forum with similar memory and componemts have tryed to this MAT function.
Must it be "Turbo" or "Ultra turbo" to activate MAT?
How much performance do I gain by this.....do I notice it in games....Battlefield 1942 for an example..or?
If the system do not like it...what happens, shutdown or? unstable?
Please give some advice.
Mr Lithesteel

MAT will give you at least a 5% increase in memory bandwidth when set to turbo mode regardless of the brand of memory you have. I own a pair of generic value ram and i see an increase of around 5 to 10 percent memory bandwidth when turbo mode is on, however my sytem fails to boot when MAT is set to ultra turbo, try to mess with the bios so you could figure out the best configuration of your system (you could measure memory bandwidth with sisoft sandra http://www.sisoftware.co.uk/), By the way your system is prepped up for hyperthreading, you own an 865pe which means your board is ready for hyperthreading, now unless you own the first generation of pentium4 procs which does not support ht, you are all set to run with hyperthreading, it would be nice if you upgrade to win xp pro or at least win2k so that you would be able to maximize your system's potential, Win XP home edition does not support multi-threading so youre loosing a lot of performance with it. Hope i helped you with your question.

Class conflict when programmatically editing graphs with property node

I am trying to programmatically move the cursors on a graph. I want the cursor to look the same on 2 different graphs so I made a subVI. The code works correctly when I have seperate property nodes, but when I try to use the subVI, I get a class conflict -
"You have connected a refnum of one type to a refnum of another type and both types are members of some class hierarchy, but there is neither a simple up cast nor type cast between the two classes."
I am not sure how to fix this. The graph that works is of a waveform, and the graph that doesn't is the output of the FFT Power Spectrum VI. Is the problem that the inputs are different? Or is there some kind of resource conflict when using property nodes in subVIs?

A shot in the dark here. But maybe if you make the subVI's input reference of type GraphChart it would work.

Significant digits not obeyed when value set through property nodes

Hi, I have a front panel with a large number of indicators on it. As updating each one is a very straight forward task, I am using the This.Panel.Controls array to step through and update each indicator appropriatly. The problem is, that because I have so many indicators, and the actual numbers aren't that important (they are also being logged elsewhere) I only wish to have 4 significant digits displayed so that the value fits into the size of the indicator. I set each indicator to have a display format of %_4f, but when I run it this is not obeyed and 7+ digits are displayed. I'm guessing this has something to do with updating the controls via the property node, but I'm not sure why that should cause an issue. Any ideas?

Nope, I double checked the format string. I do mean significant digits by the way. My imput values are expected to be in the range 0-100 but I've sized my indicators to fit only 4 digits, which will give me at worst a 0.1% error over the full range, which is good enough. Right now the channels from which I am grabbing data are all disconnected, so I am just getting noise. I've attached images of both the format string I'm using, the relavent part of my code where I update values, and an example of the output I get. Thanks,
Jon

Is there an audible loss of quality when converting from WMA to MP3/AAC?

Just wondering when I convert my WMA files to MP3 or AAC using EasyWMA, iTunes for WIndows, Switch or whatever, will there be an audible loss of quality in the conversion?
Thanks.

There is always an audio quality degradetion while converting a compressed file from one codec to another. It may not be significant for everybody tough.
To avoid this degradation, you should compress your file from the original instead of passing from one codec to another.

Problem when I make Read Only Property True

Dear Members,
I have an OAF Page on which I have the below two items:
1/ item1
2/ item2
These two items are message input text items and these two items will always have some value.
To meet one of my requirement, I am making the READ ONLY property of these two items to TRUE in processRequest method of page CO using PPR Concept. After this when I am trying to access the values of these two parameters in processFormRequest method using pageContext.getParameter method I am getting the Null Pointer Exception error.
Kindly please help me in resolving the above error.
Note: I have created a transient variable hdr1Trans and attached this variable to the both the items i.e., item1 & item2
Code in my processRequest method is as follows:_
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
OAApplicationModule am = pageContext.getApplicationModule(webBean);
OAViewObject pvo = (OAViewObject)am.findViewObject("pprPVO1");
pvo.setMaxFetchSize(0);
Row newRow = pvo.createRow();
pvo.insertRow(newRow);
OAViewObject vo = (OAViewObject)am.findViewObject("Headers_VO1");
String status="";
status=vo.getCurrentRow().getAttribute("Status").toString();
if(status!=null && !("".equalsIgnoreCase(status)))
if(status.equalsIgnoreCase("IN PROCESS"))
pvo.getCurrentRow().setAttribute("hdr1Trans",Boolean.TRUE);
else if(status.equalsIgnoreCase("NEW"))
pvo.getCurrentRow().setAttribute("hdr1Trans",Boolean.FALSE);
Code in my processFormRequest method is as follows:_
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
super.processFormRequest(pageContext, webBean);
OAApplicationModule am = pageContext.getApplicationModule(webBean);
String headerId ="";
System.out.println("test-1");
String item1=pageContext.getParameter("item1").toString();
String item2=pageContext.getParameter("item2").toString();
I am getting the NPE error when I am trying to access a record with status value IN PROCESS.
Once I make the read only property to TRUE for both the above 2 items and after that if iam trying to access their value using pageContext.getParameter Iam getting this error.
Kindly please help me in resolving this error.
Many thanks in advance.
Best Regards,
Arun Reddy D.

Arun,
When you set item as readonly field, it will always show null when you will use pageContext.getParameter("<itemID>").
If there is a VO attached with these items eg- item1, item2 then you can get the value using below code
OAViewObject vo = (OAViewObject)am.findViewObject("<Some Vo>");
String item1=(String) vo.getCurrentRow().getAttribute("<Attribute Name>");Regards,
Gyan

Major Performance Loss when the charger is plugged in

I have a Toshiba Satellite L50D-ASTNX, and have been noticing severe performance loss when I have my charging cable plugged in, whether it is losing frame rate in a video game, or receiving extreme stutters and cpu underruns when producing music on FL Studio 11. When I'm not plugged in my performance is great on high performance mode, but the second I plug in my charger I receive an instant and noticeable drop in performance and IT IS FRUSTRATING to say the least. This has nothing to do with my battery settings, nor does it have anything to do with my advance power settings because I have checked all of that. If anyone has a solution to this please let me know because I'm tired of getting only an hour of use on my laptop before I have to plug the charger bac in and leave it alone since it struggles to perform when charging.

Hey cacobo,
I found an article that can help with troubleshooting an iPhone's receiver or speakers.
iPhone: Can't hear through the receiver or speakers
http://support.apple.com/kb/TS1630
Verify that there is nothing plugged in to the headset jack, including headsets, headphones, or adapters.
Make sure the Ring/Silent switch is not switched to silent.
While on the Home screen, adjust the volume buttons. If you see the icon below, indicating that headphones are attached, there may be debris or an object lodged in the headset jack:
Check the headset jack. If there is an object lodged in the headset jack that is not easily removed, have the iPhone serviced to remove object.
For Original iPhone: If there is light debris, such as lint, in the headset jack, try connecting a pair of headphones to the headset jack and then remove the headphones. Repeat this several times to remove the debris.
If you have installed a protective film on the display, either ensure that the receiver is not covered or remove the film completely.
Check the receiver mesh (which is on the top front of the device, above the display). If it appears blocked, use a clean, small, dry, soft-bristled brush to carefully and gently brush away any debris.
If you have paired with a Bluetooth headset that is nearby, either use the headset or turn Bluetooth off (chooseSettings > General > Bluetooth).
Restart the iPhone.
If restarting the iPhone doesn't resolve the issue, try restoring the device.
If the issue persists, go to the Service Answer Center - iPhone for information on service.
Hope that helps,
David

Loss or Gain account trigger while transfer posting

Hi Experts
When we are doing Transfer Posting from Project to Unreistricted use stock within same valuation area
the 'Expense/revenue from stock transfer' key is getting triggered while doing the transaction. Can any one explain how there can be a loss or gain while doing the transfer posting with in same valuation area?
Thanks
SAS

Hi,
Generally, Sales Order Stock and Project Stock get valuated separately at Sales Order and Project level. And will not get valuated at MAP.
So when you transfer material from Sales Order OR Project Stock to Own Stock then if there is difference between Sales Order OR Project Stock Value and MAP of material then this loss/gain will arise.
To check Sales Order OR Project Stock Value, go to MBBS and compare it with MAP in MM03.

My performance is very slow when I run graphs. How do I increase the speed at which I can do other things while the data is being updated and displayed on the graphs?

I am doing an an aquisition and displaying the data on graphs. When I run the program it is slow. I think because I have the number of scans to read associated with my scan rate. It takes the number of seconds I want to display on the chart times the scan rate and feeds that into the number of samples to read at a time from the AI read. The problem is that it stalls until the data points are aquired and displayed so I cannot click or change values on the front panel until the updates occur on the graph. What can I do to be able to help this?

It may also be your graphics card. LabVIEW can max the CPU and you

Loss of quality when flipping and speeding up video

Hi,
I have Adobe Premiere Elements 12. I’m running it on Windows 7, Intel 2.5Ghz, 6GB RAM. The input video is shot on a Sony DSLR, AVCHD/MPEG, 25 fps, 1920x1080.
I am trying to video myself drawing and then speed it up. However there is a significant loss of quality after I’ve done a vertical flip, horizontal flip and sped up the video. The video appears grainy and jittery. I’ve tried a number of combinations. When I make no changes to the video then the output is fine. The main loss of quality seems to come when I do the horizontal and vertical flip.
Any tips on how to reduce the loss of quality or where to read to learn about this would be greatly appreciated.
Thanks,
Laurie

Thank you for your speedy response. I am new to the program and it is hard to take on faith after I work on an 80 plus image sequence that they render out ok, since the display in thew viewer is so poor. I did render it out to QT, and yes, the animations play cleanly.
However there is a secondary problem. Still photos are crisp and clear, however any photos with motion keyframes become soft. At first I thought it was only a problem with my .psd sequences, but the problem persists with non layered image files as well. I come from a photo background, and I know not to expect the resolution from a print, but the poor image quality/bluriness/softness of my keyframed images is noticeable to non-photo types as well.
Thank you again.
