Site refreshed from dynamic data.

I have a site stubb out that has multiple accordian canvases
each containing a tree. In my header area I have a combo box that
give you a list of clients. When you select a new client, I want to
reload all the trees in each accordian cavas with that clients
data.
I have played around and am able to do this setting a click
event on buttons that will call the send method on my HTTPService
object, and it appears to work, but I dont have a lot of control
over the data, and my implementation is pretty "clunky".... I am
looking for high level suggestions as to a best practice to
dynamically load data via http calls and refresh page data.
I am not very well versed in Actionscript, but am wondering
if I should be building a majority of the site through actionscript
objects instead of mxml. This will be a much bigger learning curve
for me, but I am assuming it will give me a much more flexible
site.
Please let me know if you have any comments or resources that
describe what I am trying to do... Thanks, Mike

hi
Working with flex involves learning at least 2 languages, the
flex language both mxml and actionscript and usint it in a
combination, but to have a dynamic site you also need to know a
backend language like C# or VB.NEt, PHP , also is useful to know a
little about Databases, because if you want a dynamic site it will
involve data for sure and where do youget data from? A database.
You will build much of your site in actionscript that is a certain,
because mxml is very good but itself is not sufficent to do
everything you want.

Time stamp from dynamic data

I trying to write dynamic data to a file using Express VI (Write LabView Measurement file). The dynamic data comes straight from a simulated Signal Express VI. The signal part of the dynamic data is written correctly but the time stamp is what appears to be float counting the seconds since the Write LabView Measurement file Express VI was started.
I have configured the Simulate Signal VI Time stamp to absolute data and time option.
This should be dead simple but it just do not work!
Any suggestion to what I might do wrong?
I do expect that the time stamp would be written as two columns one for date and one for time.
Thanks,
Soren T. Jensen

The timestamp is written in the header of the file. The time and date entered there is the time and date that you are looking for. The timestamp written next to each piece of data is indead a relative value. It is the delta from the timestamp in the header to the time that datum was collected (created). The reason for this is that timestamps are quite large in bytes, especially if you break out the time and date in strings. Just stamping the header and providing the offsets is much more efficient.
If you choose to not provide a header, I think that the timestamp will be lost entirely. I think that this is probably wrong, but I am uunsure what should be done to correct it.
Hope that this helps,

Calculation of relative position from dynamic data

I have developed this code for plotting the voltage from the PSD(Position Sensitive detector) in terms of position in LabVIEW. It gives me the exact map of the position of the LASER beam on the PSD, on the graph in LabVIEW.
Now what I need to do is calculate out the relative displacement between two positions of the spot. Suppose at time t1 the position is at A(x1,y1) and then at time t2 it moves to B(x2,y2). I know the mathematical formula for the displacement from A to B.
But my problem is how do I get the values of (x2,y2) and the previous position value of (x1,y1) dynamically. I need to do this continously al long as the experiment gos on and then also save it.
Thank You for the help.

Thank You for the reply Sir, but the problem is how do i compare the values of x,y. I am not able to extract the vales from the graph/array for 2 consequtive times.
After you use the 'Split signal' function, right after your 'DAQ Assistant', you should have a signal of X values, and one of Y values.
Convert each of these signals to type DBL. They should now be 1D arrays of type DBL.
Then, you can do the following, since For Loops auto-index:
Edit: In my example, I switched the X and Y inputs ,
however, in this circumstance, it doesnt matter for the formula used.
Either way, in your VI you could correct that if you want.

Extract data point from dynamic data based on time index

My goal here is to find out what the frequency of pulses from object B is given an input to object A, and not only that, but what the frequency is at a particular moment in time.
While in this example, the DAQ Assistant reads the data and will show it nicely on a time-indexed graph, the convoluted mess above is the only solution I have thus come up with to extract a specific item from that set of data. I was/am hoping there is a more elegant solution. However, I can confirm via other sources that the data from the DAQ Assistant is incorrect, possibly/probably because the DAQ units being used are on different chassis, using different counters (I've got to work with what I've got available) and won't cooperate in the same while loop.
In this example, the data being read is correct, I cannot display the result on a graph (nothing shows up, but the autoscale of the Y axis seems to work), and the VI occasionally (but not always) ends on an Error -200474: Timeout (with the signal no longer being sent to object A, I don't expect any pulses from object B). I would like to have both the graph and the value (data point) at time index, like I was getting in example one, but the correct data, as I was getting in example two.
Code for both examples is attached.

Check out the acquisition mode of DAQ assistant, Its configured to 1sample (on demand) which means that graph is plotting only 1 sample (only 1 data point) which you are unable to see. Modify the settings to acquire greater samples so that a plot can be seen on the graph or use chart to plot the points which has history with it.
The terminology "object A and B" that is used is not clear and what it is pointing to (while loop or the images itself).
The second figure there is a data dependancy between 2nd while and 1st while loop. Try using standard LabVIEW Design patterns

Dynamic Data Source with Flash file

I have a MySQL database which I am using to create a dynamic
table for a shopping website. One of the fields of the database is
for a video of each product. In the videos directory is a bunch of
flash movies (.swf).
In Dreamweaver I have a dynamic table that is using the data
from my MySQL database. When I preview the site all the dynamic
data works fine and appears correctly. However the video does not
work when I preview the site. The steps I made to create the dyamic
video link in dreamweaver are as follows:
Insert>Media>Flash
Select File Name From: Data Sources
Field: Recordset>Video
I've checked the information in my MySQL database and the
data there seems to be correct. If I remove the dyamic video
information and manually place the necessary flash video and
preview the site it works fine.
So why won't my flash videos work dynamically?

If it is open, then try
Named range: ConsolLink = Range("Consol File.xlsm'!Source_OpexConsol")
And if it is not currently open, then try
Dim W As Workbook
Set W = Workbooks.Open("R:\Root\Sub1\Sub2\Consol
File.xlsm")
Named range: ConsolLink =
Range("Consol File.xlsm'!Source_OpexConsol")
W.Close False

What server language are you using? I have used a server
component
called www.asppdf.com which is fairly expensive, but can
create PDFs on
the fly from dynamic data. Its comlex, but worth the effort.
There are other solutions for PHP and CF, but no extensions,
so will
need some serious coding.

Convert "1D array of dynamic data" to "Dynamic data" after auto-indexing with loop

Hi -
I have a question about how exaclty auto-indexing works with the Dynamic Data type when exiting a while loop. I'd like to use the DAQ assistant to record data through an analog input (on the MyDAQ) and then replay that data through an analog output. This works fine if I use the DAQ Assistant to record data for a set amount of time:
However, I run into trouble when I try to use a While loop with a stop button to record data for an arbitrary amount of time. I set the dynamic data tunnel out of the While loop to "Indexing", but then when it exits the loop, it becomes "1-D Array of Dynamic Data" instead of just "Dynamic Data", and get a broken wire when I try to connect it to the input of the DAQ Assistant. I've also tried converting the dynamic data to Array and Waveform data types inside the loop, but have the same issue (they become 2D Array and 2D Array of Waveform respectively when leaving the loop). Try as I might using blocks like Convert to/from Dynamic Data Type, or Array Subset, I'm unable to get them back down to just Dynamic Data or Waveform, which will be accepted by the DAQ Assistant:
One other small note - I'm not sure if using the "Build Array" function with a shift register accomplishes exactly the same thing as just auto-indexing an array out of the loop - so I've tried both, but still have the broken wire issue.
I'm assuming this is just a simple issue of using the right block to convert "1D Array of [Something]" to just plain [Something]. Any help appreciated.

Attaching a Cluster of 2 elements data type to dynamic data type wire.

Hey Folks,
How do I attach a cluster of 2 elements data type of wire with a Dynamic data type wire?
Or a Build XY Graph to a curve fitting2.
Thanks for the help.
Ty

Hi Ty,
Try to use the "Express-VI Curve Fitting" which is at: Functions-> Signal Analysis -> Curve Fit.
You have to put this VI before the "Build XY Graph".
Otherwise, u can convert the siganls types by using the "Convert from Dynamic Data"
which is at : Functions-> Signal Mamipulation -> Convert from Dynamic Data.
Hope it Helps....

Compare scalar value to dynamic data

I am trying to compare a scalar number input in the front panel to a dynamic data set(from DAQ) and return a boolean true if the condition is met. How can I compare one value to each data point in the acquisition data set?

You can use the Convert From Dynamic Data and convert to a 1D array. The comparsion functions work with an array as one input and a scalar as another. The output is a Boolean array - the results of each element in the array to the scalar. I think you can also use the Comparison Express VI but I have seldom used any of the Express functions so I'm not sure about that.

Determining what site(s) has not refreshed from master database

Is there a way to determine what sites have refreshed at the master level ? Is there a system table or v$view that contains this information ?
I have a master read-only snapshot setup with an oracle 8i master and oracle 8.04 snapshot sites(54). I want to prevent my mlogs from getting too large and determine which sites have not refreshed as an aid to keeping the system healthy.
Any hints/help/pointers to documentation will be greatly appreciated !

Powerpivot Error on Refresh -- "We couldn't get data from the data model..."

I'm using Excel 2013 and Windows 8.1. I have a spreadsheet I've been using for over a year, and I've just started getting this error message when I try to refresh the data.
"We couldn't get data from the Data Model. Here's the error message we got:
The 'attributeRelationship' with 'AttributeID' - 'PuttDistCat9' doesn't exist in the collection"
Any idea how I can fix this problem? I haven't changed anything related to that particular attribute. All the data is contained in separate sheets in the workbook, so there are no external sources of data.
Thanks.
Jean

Thanks for all the suggestions.
I found a slightly older version of the spreadsheet that still refreshes properly, so I don't think I have any issues with the version of Excel or Power Query. (I've had this same error before, and I believe I applied the hotfix at that time.)
I think this problem started after I updated a number of the date filters in the pivot tables. I haven't made any changes to the data model, and the only updates I've made were to add data (which I do all the time), and to change the date filters on
the pivot tables.
As suggested, I added a new pivot table querying one table (the table with the attribute that shows up in the error message), and it worked fine. I can also refresh this pivot table.
Then I tried adding a pivot table which went against several tables in the data model (including the table in question). The pivot table seemed to return that data properly. However, when I tried to refresh it, I got the same error message ("we
couldn't get data from the data model...").
Dany also suggested running the queries one at a time to see which one is in error. Without checking all the pivot tables, it appears that any which use the table "HolePlayedStrokes" generate the error (this is the table with the attribute
mentioned in the error message). Pivot Tables without that particular table seem to refresh OK. Unfortunately, that is the main table in my data model, so most of the pivot tables use it.
Any other suggestions? I'd be happy to send a copy of the spreadsheet.
Thanks for all the help.

How to delete data from dynamic internal table

Hi,
I have dynamic internal table and I have some slection screen fields , using these selection screen fields
(select -options), I have to filter the data? assigning will work with READ , but I have select options not the parametre,
and also delete will not work for dynamic table..
as we cannot use assigning with delete..
So how to do this?
and one more thing is , I cannot filter the data while selection( in select, I cannot filter the data-> as it's not coming directly from table, it's coming from buffer),
so now after selection of data, I need to filter the data from dynamic table.
Is there any way to do this?

How to save the dynamic data from a pressure sensor

Hello Everyone,
We have a FPGA board NI cRIO-9073, a temperature module NI 9217 and a pressure module NI 9203. Right now we have problem with saving the data from pressure sensor. I succeed in getting and saving the data from the temperature sensor. Then I just simply modify the FPGA VI and host VI of the temperature function block which are shown in the attachment files.But I get an error saying I cannot connect two different data types.
Could anyone here give me a help on this?
BTW: we are using a 2 wired pressure sensor with 4~20mA. The brown one is +Vcc and the white one is GND.I connect the white one with the COM of NI 9203 and the brown one is connected to AI7. DidI make a right connection?
Thx for any help from anyone!

Reading the Data from dynamically added rows of a table...

Hi,
              I am using adobe interactive form (WD ABAP) in which i am adding the table rows dynamically (using Jscript code). I have to fech these data into an internal table. But I can read only the first row data..
              Also While adding rows dynamically the same data is repeating for the consecutive rows..
              I have found many similar posts in sdn, but i cannot get the solution. They have mentioned about adding in WDDOINIT method. Can anyone explain me what should be done,..?
1) How to solve repeatative data while adding rows..?
2) How to read dynamically added row data during runtime into internal table..?
Thanks,
Surya.
