How do we create a PY Constant

Hi,
How do we create a PY constant in T511k table and how do we link that with a specific field of a screen.
That means when we update the field of a screen then the PY constant should be updated.
Kindly through some knowledge in this issue.
Thanks,
Tanu.

Thanks for your valuable suggesstions.
My requirement is like,
I have to edit a PCR where the PY constant has required to be compared with the existing value. For this calculation I need this constant( Value) to be in v_t511k table. I know we can create that in this table.
I have created in the same procedure but when I changed some value in my required field in the screen, the PY Constant is not been updated autometically.
Do we have to create any link between them so the the constant is updated autometically or we need to update the constant each time in the t511k table.

How to create a dynamic constant?

Hi everyone,
I would like to create a dynamic constant similar to CATEGORY_dim or TIME_dim for the dimension AcctDetail, and then be able to link it to Script Logic in order to use it there. Does anyone know if this can be done?
Thanks very much.

Hi Bzaratev,
No need to add a new dynamic constant. You can use dynamic script in the DM side like this,
PROMPT(SELECTINPUT,,,,"CATEGORY,P_CC,TIME")
You just directly wirte down the dimension name.
For the standard usage, we use format %{XX}_DIM", XX is the dimension type.
PROMPT(SELECTINPUT,,,,%CATEGORY_DIM%%ENTITY_DIM%%TIME_DIM%)
So if you want to use AcctDetail, you can just write it PROMPT(SELECTINPUT,,,,"CATEGORY,P_CC,TIME,AcctDetail")
Hope this helps.

How can I create a Teststand (1.0.3 or 2.0) distribution without having all of the VIs (6.0.2 or 6.1) in the same directory?

How would I create a Teststand distribution of LabVIEW VIs and maintain the test VI directory structure that I want?
I know that I have to use the application builder to build the custom operator interface, configure it as an ActiveX server, and launch the Teststand engine installation.
The only problem that I have is using the VI packager which puts all of the test code and sequences in a single directory.
This gets quite messy. There are just over 1000 files in the neatly orgainzed directory structure that I have now. (this includes support files, dll's and such)
I have read brief appnotes on configuring the ini file(s) to use
the vi search path that I want, but have not been able to get this to work. Maybe I'm not updating the correct ini? or have to include each subdirectory?
I have currently upgraded from LabVIEW 6.0.2 to 6.1
I am currently using Teststand 1.0.3
I have not upgraded to Teststand 2.0 yet because I have not decided if I want to build at this revision or go through the extra work to mass compile Teststand at LabVIEW 6.1, install the LabVIEW 6i VI Packager Fix, and update the new Teststand LV operator interface with my changes.
At present, I'm not getting the results I want and am quickly running out of time. I have to deliver the project by the 14th of July 2002.
Sorry for the long question and thanks for you help.

Hi,
I dont think the problem is really related to using the VI Packager but more to how the OI interface applications relates to labVIEW File constants.
If you are using the LabVIEW as the ActiveX Server then there should be no problems. But if you are using the Runtime LabVIEW server such as 'TestStandLVRTS' then the file constant would return different paths.
eg for the Default Path you would get 'C:\TestStand\Components\User\RuntimeServers\LabVIEW' instead of 'c:\Program Files\National Instruments\LabVIEW'.
Attacted is an example to show how to change these paths when using your runtime server. Unzip this into your teststand examples folder
Put the INI file in the location of the \user\runtimeservers\labview folder.
Change the labview adapter t
o use TestStandLVRTS.exe. You can run the example sequence from either the OI or seqeditor.
I hope this helps

How do you create an array without using a shell on the FP?

I want to be able to read the status of front panel controls (value, control box selection, etc.) and save it to a file, as a "configuration" file -- then be able to load it and have all the controls set to the same states as were saved in the file. I was thinking an array would be a way to do this, as I have done that in VB. (Saving it as a text file, then reading lines back into the array when the file is read and point the control(s) values/states to the corresponding array element.
So how do I create an array of X dimensions without using a shell on the front panel? Or can someone suggest a better way to accomplish what I am after? (Datalogging doesn't allow for saving the status by a filename, so I
do not want to go that route.)

Thanks so much m3nth! This definitely looks like what I was wanting... just not really knowing how to get there.
I'm not sure I follow all the icons. Is that an array (top left with 0 constant) in the top example? And if so, that gets back to part of my original question of how to create an array without using a shell on the FP. Do I follow your diagram correctly?
If I seem a tad green... well I am.
I hope you understand the LabVIEW environment and icons are still very new to me.
Also, I had a response from an NI app. engineer about this problem. He sent me a couple of VI's that he threw together approaching this by using Keys. (I still think you are pointing to the best solution.) I assume he wouldn't mind m
e posting his reply and the VI's for the sake of a good, thorough, Roundtable discussion. So here are his comments with VI's attached:
"I was implementing this exact functionality this morning for an application I'm working on. I only have five controls I want to save, but they are all of different data types. I simply wrote a key for each control, and read back that key on initialization. I simply passed in property node values to the save VI at the end, and passed the values out to property nodes at
the beginning. I've attached my initialize and save VI's for you to view. If you have so many controls that this would not be feasible, you may want to look into clustering the controls and saving the cluster as a datalog file.

How do I create a 1d array that takes a single calculation and insert the result into the first row and then the next calculation the next time the loop passes that point and puts the results in thsecond row and so on until the loop is exited.

The attached file is work inprogress, with some dummy data sp that I can test it out without having to connect to equipment.
The second tab is the one that I am having the problem with. the output array from the replace element appears to be starting at the index position of 1 rather than 0 but that is ok it is still show that the new data is placed in incrementing element locations. However the main array that I am trying to build that is suppose to take each new calculation and place it in the next index(row) does not ap
pear to be working or at least I am not getting any indication on the inidcator.
Basically what I am attempting to do is is gather some pulses from adevice for a minute, place the results for a calculation, so that it displays then do the same again the next minute, but put these result in the next row and so on until the specifiied time has expired and the loop exits. I need to have all results displayed and keep building the array(display until, the end of the test)Eventually I will have to include a min max section that displays the min and max values calculated, but that should be easy with the min max function.Actually I thought this should have been easy but, I gues I can not see the forest through the trees. Can any one help to slear this up for me.

I didn't really have time to dig in and understand your program in depth,
but I have a few tips for you that might things a bit easier:
- You use local variables excessively which really complicates things. Try
not to use them and it will make your life easier.
- If you flowchart the design (very similar to a dataflow diagram, keep in
mind!) you want to gather data, calculate a value from that data, store the
calculation in an array, and loop while the time is in a certain range. So
theres really not much need for a sequence as long as you get rid of the
local variables (sequences also complicate things)
- You loop again if timepassed+1 is still less than some constant. Rather
than messing with locals it seems so much easier to use a shiftregister (if
absolutely necessary) or in this case base it upon the number of iterations
of the loop. In this case it looks like "time passed" is the same thing as
the number of loop iterations, but I didn't check closely. There's an i
terminal in your whileloop to read for the number of iterations.
- After having simplified your design by eliminating unnecessary sequence
and local variables, you should be able to draw out the labview diagram.
Don't try to use the "insert into array" vis since theres no need. Each
iteration of your loop calculates a number which goes into the next position
of the array right? Pass your result outside the loop, and enable indexing
on the terminal so Labview automatically generates the array for you. If
your calculation is a function of previous data, then use a shift register
to keep previous values around.
I wish you luck. Post again if you have any questions. Without a more
detailed understanding of your task at hand it's kind of hard to post actual
code suggestions for you.

How do I create an ACR custom lens profile if camera exposure can't be set to manual?

How do I create an ACR custom lens profile if camera exposure can't be set to manual?
I ask this question for the Nokia 808 PureView 41MP camera. It produces stunning image quality but exposure can only be controlled via EV +/- compensation. I need a lens profile to correct for vignetting to get even skies in panorama (which turn out stunningly otherwise). There is no profile for the Nokia 808 PureView I am aware of and I'd like to produce one.
Is the Adobe profile creator able to correct for varying exposure using EXIF or overlapping parts of the chart or background?
Or would the Adobe profile creator ignore EXIF if I use studio flash to enforce a constant lightning situation, even if shutter speed would vary (aperture is constant and ISO can be set constant, just not the shutter speed)?
Or did Adobe produce a profile internally they can share?
Thanks.

If you read the first post, this is the camera-app of a 41MP Nokia Pureview 808 camera-phone, so maybe someone could write a new camera app but the phone is Symbian OS which is dead, making that unlikely.
http://www.digitaltrends.com/mobile/the-skeptics-guide-to-nokias-808-pureview-five-reasons -41-megapixels-are-not-a-gimmick/
http://www.digitaltrends.com/mobile/the-nokia-lumia-820-and-lumia-920-too-little-too-late/
It would probably be easier for Adobe to rewrite the LPC to allow vignetting to be computed from a single shot of a blank wall without a target in the shot, than to have someone rewrite a camera app that allows manual exposure.
Another idea about how to get the phone to keep a constant exposure would be to experiment with putting darker and lighter objects in the field-of-view away from the target area to make the camera metering adjust things so it’s exposure is the same from one shot to the next. This would take some doing but should work, unless the LPC uses the part of the frame that doesn’t contain the checkboard target in its computations.
You’re basically varying the scene around the target so the camera takes the same exposure of the target each time.

How do I create a print button to print a specific range of the document.

How do I create a print button to print a specific range of the document. I've found JavaScript to print a specific page, but a range or even multiple ranges. Form is created in Adobe 9 Pro. Any help would be truly appreciated!

Sure, I'll give it a test. Its just that I have a 128 page form that not all of it needs to be printed.
Currently, I have an index page where I want to set up a print button queues per form, however there are several form scattered throughout the document that make up a specific section, but it does not require printing the entire document. Does that make sense?
I did find this JavaScript during my reseach, but have not be able to get it to work.
var pp = event.target.getPrintParams() ;
pp.interactive = pp.constants.interactionLevel.full;
pp.printRange=[[1, 1], [3, 4]];
event.target.print(pp);

How can I creat or open an excel file in labview?

I am using Labview 7.1 and report generation toolkit. I got the example code from this address :"Creating a report in Microsft excel using the labview report generation toolkit"
But seems this example only can creat report when the excel file exist, otherwise it will get error code 7.
How can I creat a new file if it doesn't exist and open the file if it exist? Can I creat a report without openning excel because I need to creat more than one report and check it after the test.
Thanks

Simply use the "Open/Create/Replace File.vi, and wire a constant "Create / Replace".
Wire a path/filename and make sure the name ends with the extention .xls
If you have multiple lines (likely), place aech line in an array and use the "Array to Spreadsheet String.vi" before sending it to "Write to file.vi". Don't forget to close the file.
Hope this helps..

How do i create arrays more efficiently

how do i create arrays more efficiently?... need to insert data into an array every loop iteration. I am using the insert into array function and shift registers. I have been told this is inefficient... and they are right because I can make the program stop and it gives me the error that labview does not have enough memory. A coworker said to avoid shift registers and investigate property nodes... i am new at this and don't know what this is exactly.. is there a tutorial on efficent data handling.. or examples that would be usefull?

tbob wrote:
Mark is absolutely correct. Indexing will take a lot of memory and a lot of time when the array gets large. Indexing is great for small arrays though. With indexing, the first loop iteration will create an array of size 1. On the next loop, the array has to be copied, re-dimensionedcto size 2, old data copied to new array, and new data inserted at end. You can see how this will become a monster with an array size of 10,000. With pre-allocation, there is no re-dimensioning and no copying. Array elements are simple replaced. And yes you do have to know the upper limit to use pre-allocation. Kudos to Mark for pointing out the facts.
A bit of a clarification is needed. Folks from NI told me that LabVIEW tries to be smart when autoindexing. When they allocate the memory the initial chunk of memory it is larger than a single element. So you don't necessarily get a copy and allocation every iteration. They may have improved the optimization to preallocate the complete array if the size is already known (a constant wired to the loop count). However, they would have no way of doing this if the number of iterations is not known ahead of time.

How does labview create a hyperlink in a web page?

Hi
I was wondering, how does labview create a hyperlink in a web page?
Thank you.

Hi,
What do you wish to do?
The most primitive way is to generate a .HTML file.
Type your HTML codes (Using string constant) and save it using "Write Chars To File.vi" using a filename with extension .html
Hope I am addressing your question.
Cheers!
