Compare the previous values of a control?
Hello! I am communicating with via GPIB hardware. I'm rebuilding software to control the unit. Unfortunately, the GPIB bus is "clogged" with a lot of almost synchronous calls to the GPIB. In order to solve this problem, I would only request the GPIB, if a control on the front has been changed by the user. For example, to change a constant in time, the user changes the value in the control of constant front of time. An instant more later, a request is sent to display what unit was defined as the time constant. I wish that this request to the device will only be sent if the user has actually changed the value of a constant control of time. All calls are transmitted in time loop. Is there a simple and lightweight way to check if a control value has been changed? Thanks in advance for any help!
The structure of the event is your best friend here. Use a value for orders change event.

How to check the previous value of the element in a multi-record block
Oracle Version: 10 g
Forms Version: 10 g
Hi all
Hello everyone, I have a multi-dossier block in a form where one of the values of elements is of LOV.user can select the value of LOV.
If once the user selects the value of LOV and moves to the next of the multi-file record, and selects the value of LOV again, I shouldn't allow users to select the previous value of the user in order to avoid duplication of records.
and important remark is that I should get there before you save it in the database because once registered in the database I can compare the values and hide the previous value.
Any help will be appreciated.
Thanks and greetingsThis is a question frequently asked in the forum! There are several different solutions. Take a look at the following articles. Both will perform the necessary verification of duplicates.

Select list value is changed to the previous value.
I have a selection list. When the user leaves the page, I reset the selection list to a default via javascript. However, when the user returns to the page, the selection list is in some sort to reset the previous value, the user has selected.
What is the cause, or how I can fix this problem?Hello
You could have what ever in the HTML by JavaScript document.
Check the status of the database session. In the developer toolbar, there is option for that.
http://download.Oracle.com/docs/CD/E17556_01/doc/user.40/e15517/concept.htm#sthref108Also check that you have all the calculations and what is your source of point.

Compare Current metric custom with the previous value
Hello
It's simple, no doubt, but I can't find the answer anywhere. First of all, a bit of background.
A customer asked us if Foglight can monitor a particular file. If it has not been updated in 30 minutes, something is wrong therefore to trigger an alarm.
Foglight can do out of the box, but I wrote a script and used the Script Agent Builder (thanks to http://en.community.dell.com/techcenter/performance-monitoring/foglight-administrators/w/admins-wiki/6155.custom-script-agent-1-leverage-an-existing-monitoring-script-to-push-data-into-foglight for the modification of the file time. This script:
off @echo
(for %%d to do (C:\Scripts\useful.txt) (for /f "tokens = 1-2" %% in (' echo % ~ your ') do (set _modified = % H)))
@rem generate the results in the form of script agent
echo FILE_LAST_MODIFIED of TABLE
echo START_SAMPLE_PERIOD
echo message. StringObservation.obs=%_modified%
echo END_SAMPLE_PERIOD
echo END_TABLE
.. can every 30 minutes via the agent and the product of output such as:
Note that this test file is, in general, static; I would update manually to test as I did above to display the time of 15:03 updated change.
However, I can't work on how to program the alarm status. I know what I want to do:
If #message.current # == {#message.previous #}
Returns true;
}
else {}
Returns false;
}
.. .but simply does not how to get previous value.
Can someone help me please?
Thank you

I went in the way of thinking, that it was a metric based on your initial code, but take a look at the screenshot, it appears to be a string. If delta will not work.
I * think * work delta on datetime data type, so if you can make to your script at the beginning, it would simplify.

Insert row into table 2D retaining the previous values
Amendment of data entered in a 2D array and also displayed a table. When the time rolls 3 columns of data are held and then created line. Problem is the line moves downwards, but the previous data is not stored. I tried using shift register, but that only auto markings lines table to fill as the iteration of the loop. Looks like a basic really simple problem but going round in circles on this one there...
In this case, the function 'Replace table subset' is what is needed to replace the last values in line with the current values of the user interface.
On the evolution of the time, an addition occurs.
An update of the VI is attached.

Change the value of always the same as the previous value register
Hi all. I was banging my head against the wall for a while on it and hoping that someone can help me.
I use a USB-6008 DAQ hardware to read a rotary encoder. I pulled the rudiments of the attached VI of the forums, but I modified to work with an encoder with an index. All I'm doing is reset to the "value of the degrees to zero whenever the value of the counter (Encoder index) increases a. I thought I was good at using the shift register, since it must retain the value of the previous iteration (just before the index spent). The problem I have is that two courses to the function values ' lower to "always seem to be the same, so my 'degrees' value never resets. What Miss me?
Thank you!
PS - I need to use the meter (instead of just another digital line) because it is essential that the index value is never missed. And I know using a software based counter as this tends to miss a digital input signal here and there.
Suppose that your encoder runs at 1 rpm = 1 index pulse per second. You are turning your loop to 1000 times per second. It is not clear that the 6008 reads the line of DI and the meter that fast. The software update timed AO rate is 150 Hz, maximum. If it reads fast, get you 999 readings of 0 and a reading of 1. For 1 millisecond the degrees indicator will display 0.

Hello
I work with LabVIEW 2013. I'm receiving the channels of a robot and the analysis of the data and plot the position real vs commanded position. When the robot meets and error, it sends LV and messages. All string parsing is done in the same place, so the graph just to draw all 0 when it receives an error.
I have it such that when it detects an error, it lights a Boolean value. What I have to do now is to write the previously known values for the "true position" instead of setting them to 0. Is this possible?
A snippet of my code is attached. I get this channel 4 times per second.
Thank you
SM
Here's a quick example. If an error occurs, use the old value of the FN, if not use the new string data.

Get the current value of a control of the ring
I have a control of the ring that has the following values. See attacment. I need to get the current value of this one and use it as input for another function, but First I would like to get the current value and save ina text file. I tried this
if (event == EVENT_LEFT_CLICK_UP) || (event == EVENT_LEFT_CLICK_DOWN) { int p; GetCtrlVal (panelHandle, PANEL_RINGSLIDE_1, &p); FILE *OutFile = fopen("C:\\Users\\Student\\Desktop\\ringtest.txt","w"); fprintf(OutFile,p); fclose(OutFile); }
I need to get the current value of the ring (& p) to write to the file ringtest.txt.
Also, I need to use this value (& p) as another entry in the same program.
IE value of & p must be used in
b = c * 5; where c is the value of the current & p.
Can any 1 help?
You're right: EVENT_LEFT_CLICK_DOWN is not a valid event for the CVI. Valid events are listed in the userint.h file, and are the only events that can be caught in the trap in a point of order. On the other hand, you're assuption on EVENT_VAL_CHANGED is correct: you can trap forget the EVENT_CLICK_UP event.
According to the second question, looking at the definition for fprintf you must pass a string format as the second parameter to the function, then the value to write to the file. In your case, the correct syntax is:
fprintf (OutFile, "%d", p);

SQL use the previous value of subselect in the subselect, the right way?

Error: [1]: ORA-00904: "PARENT_ID": invalid identifier

Guaraanteed of helpful answers!
Thank you!
Hello
You can't do that. You should probably use a hierarchical query instead of your scalar subqueries to extract lines children and parents and then join the AMD_ADDRESS_PL_TMP table.
Moreover, why the clause GROUP BY here?

Compare the column values for multiple lines
I am new to oracle and I have a requirement to compare the values of column across multiple lines. If all column values are the same, I want to display that value, if the columns are not the same, I need to display 'no match' as value. I need id to group values and display a status value based on the above logic. Can anyone offer assistance with dispalying the result expected below?
Sample
Table
State ID
1 S
2 L
1 S
2 S
expected results
State ID
1 S
2 no match
Hello
That's what you asked for:
SELECT id
CASE
WHEN COUNT (DISTINCT status) > 1
THEN "no match."
For ANOTHER MIN (status)
The END as status
T
GROUP BY id
;
Want that if each State ID is NULL? The CASE expression above returns NULL in this situation.

Change event - why is does not select the current value, just the previous value?
Hello.
I use the script when the user selects a value from the drop box, something visible text (using the ' presence')
I use the change of the event, but it does not work very well. When I select a value, it does not change the text, but if I select another value, it will display the previous selected value.
Why did he not synchronize the value?
Thank you!!
Hi Rafael,.
I don't know if you are using an event well.
mouseExit is something good to use (especially when paired with the mouseEnter), during the change of the visual appearance of an object. For example, a button where the legend is underlined on mouseEnter and not highlighted on mouseExit.
If you want to change the presence of objects on the form that the flat user above the list drop-down, then mouseEnter/mouseExit should work. However, if you want the changes occur once the user selects an item in the drop-down list, I recommend the exit event.
Here are some examples:
