Get information from change of color over time
Hi all
I am new to LabView and on this forum, so I hope I'm in the right subforum. If this isn't the case, it would be nice if a mod could move this thread.
My problem is the following:
Let's say I have a white spot I want to observe with a camera. The color of the spot turns green over time and I want to acquire the photo, as well as to get the color intensity of green increase developing countries over time. I do not know what features I need to use to get there. Can someone me hint in the right direction? I think that it is at least possible in LabView.
Thank your all for your help.
Best regards
Tresdin
I don't know what the best resource for IMAQdx pilots, I think that the examples that provide OR are pretty useful. Here's a simple VI which will tell you the average value of green of all the pixels in your image.

Why can't get information from frequency of NI USB-5132
Hello
I use NI USB-5132 and try OR Scope example measure a library.
I wonder why I can't get information from the input signal frequency.
Thank you
In the flexible Panel, you need to adjust the time/Div and, possibly, the Volts/Div to get a consistent result. Make a note of the settings.
Based on what you used in the soft cover, you must change the parameters of the VI until you see a signal. If you don't see something here, then obviously you can not perform a measurement. Try other examples to see if you can capture at least the waveform.

When the press the play button, how we get information of angle in every second time bar?
You can get the values of rotation for each image by calling the method. valueAtTime() on the Rotation property. So, if you want to know what the value is at the 2 second mark...
layerObj.property("ADBE_Transform_Group").property ("ADBE Z rotation").valueAtTime(2, false); 'false' includes the results of the expression, 'true' does not work.

get information from inside a trigger of the other tables in the schema even
Addendum:
... Sorry I forgot: Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64 bit
*******************
Hello
I'm trying for a few hours to get information from inside a trigger to another table in the same pattern.
My trigger is PSE_BKB. NUM_PHANTOM_BP
I first tried a simple solution...
CREATE OR REPLACE TRIGGER PSE_BKB. NUM_TR_PHANTOM_BP
BEFORE DELETING, INSERTION OR UPDATE
ON PSE_BKB. NUM_PHANTOM_BP
REFERRING AGAIN AS NINE OLD AND OLD
FOR EACH LINE
DECLARE
v_recht NUMBER (1): = 0;
v_recht2 NUMBER (1): = 0;
v_change_mitarbeiter NUMBER (1): = 0;
v_recht_mitarbeiter NUMBER (1): = 0;
v_typ varchar2 (20);
v_obj_key varchar2 (11): = "gugus";
v_ph_key varchar2 (11);
-ph_key varchar2 (11);
v_obj_keys varchar2 (4000): = ', ';
anz_num NUMBER: = 0;
anz_num_tmp NUMBER: = 0;
anz_st_si NUMBER: = 0;
BEGIN
...
Select count (*)
in anz_num
of pse_bkb.num_objekt o
where o.obj_key in
(select distinct (ov.obj_key)
of pse_bkb.num_objekt_verb ov
where ov.phantom_key =: old.phantom_key
)
and o.typ = "NUM";
...
Explanation: my trigger table is PSE_BKB. NUM_PHANTOM_BP.
On the pse_bkb.num_objekt_verb of the table, I have a relationship 1: n to one or several object-key (field named obj_key!) on my referenced key: old.phantom_key. With this obj_key, I want to watch the weather, I have one or more lines in the table type num_objekt "NUM". So the internal selection gives me all the num_objekt_verb obj_key with my: old.phantom_key and with whom I count the number of lines I have on num_objekt with type "NUM".
The problem is that the trigger does not see the table.
I tried many variations.
The latest version I tried was with a cursor inside the trigger definition as in the block of code below.
For debugging purposes, I inserted a RAISE_APPLICATION_ERROR in the inner loop - see below. The v_obj_key variable is never defined, as in all the other variations, I tried-, I still see the predefined "gugus" in the declare section.
It seems that oracle can not read other tables at this point. La: old.phantom_key is defined (in this simple example there would come a return obj_key).
Thanks in advance for your help - and excuse my English.

Published by: user832075 on 14.01.2013 06:18The reason why you get count_n = 0 in tr_c is that there is no line in B with key_c = 17, to the moment you arrive at tr_c. The removal of B has already occurred, and since you're in a single transaction, the application for tr_c:
select count(*) into counter_n from a aa where aa.key_a in (select distinct(bb.key_a) from b bb where bb.key_c = v_ph_key ) and aa.typ = 'n';
'knows' that the row has been deleted then gets a number of 0.
I added a set of instructions dbms_output to show the order in which triggers run, and that's what I get:
SQL> delete from b_vw where key_a = 1 and key_c = 17 ; in trigger b_tr_vw In tr_b in tr_c delete from b_vw where key_a = 1 and key_c = 17 * ERROR at line 1: ORA-20077: Remark: counter_n: 0 counter_s: 0 v_ph_key: 17 old.key_c: 17 new.key_c: ORA-06512: at "OPS$ORACLE.TR_C", line 38 ORA-04088: error during execution of trigger 'OPS$ORACLE.TR_C' ORA-06512: at "OPS$ORACLE.B_TR_VW", line 17 ORA-04088: error during execution of trigger 'OPS$ORACLE.B_TR_VW'
Thus b_tr_vw trigger is triggered first and deletes a B. trigger fires tr_b as part of this statement to remove and check against A, happening apparently so no error is triggered and succeeds the removal of B. Now tr_b_vw takes back control and deletes C. Since the B line which has key_c = 17 already deleted a control for counter_n > 0 and counter_s = 0 fails and raise you the-20002 error. Note that I'm assuming that the error of-20077 you lift is just to see the values and is not intended to be part of your actual code.
Because I have really no idea what you're trying to accomplish here I can't offer a lot of advice that you might want to try entering two tr_c of the tr_b_vw trigger validation queries before deliver you the removal of b and put the counter_n > 0 and counter_s = 0 control under tr_b_vw to decide whether or not you want to remove.

There are also alarms that deal with the latency of disk. You are looking for a report or dashboard? Check the alarm Viewer and define a filter on the "latency". This will show you all the current latency time, then you can explore the host or logical unit number that is having the problem.

40L5443DG TV: how to get information while changing TV channels
Hello
My TV is a very good TV. Thank you Toshiba .But there is a but.
When I change the TV station, I don't see the kind of program. I have to press the info button to find out which .
Yes, I can use the guide button and press ok when I want to, but it is difficult to add the info automatically when I change the TV channel?
All the good digital decoder DTT is automatically displayed info.
Should I buy a new digital box and by connecting it to the smart plug ?I'm sure that you will find a good solution.
Best regards.
Mike (France)What do you mean by 'you don't see the kind of program? When you change the channel you see the program number, name and time, after pressing 'Info' you see 'Now' and 'Next' EPG information in the lower band. What is the problem with this concept from your point of view?

Get information from the low level of the Subvi ni5660
A quick explanation of the problem: I need to create several VI just to return a value of the PXI-5660 (ex: Center frequency, Span, etc.) while the entries are only a "VISA" and one "error in.»
Detailed explanation of problem: I need to create multiple VI that the properties 'Set' or 'Get' of the PXI-5660 module (ex: the Central frequency value, get frequency, etc...). Each VI must have a VISA in/out and in/out Error, but the only other present in/out should be the property of game/called. Global variables are not allowed.
One of the biggest problems for me is that ni5660 drivers do not contain a property node. I managed to (apparently) set some of the properties by feeding only a single entry in the icon 'configure ni5660 for spectrum', but the only tool that seems to be able to output all information is the icon «MT get Attributes» The release of 'MT get Attributes' does not contain many of the properties that I need good output.
I tried to use the icon 'MT get Attributes' linked to "ungroup by name" which has the value "handle receiver.handles.niScope" which feeds on the reference to a property niScope node, hoping that I would be able to obtain information through the niScope 5660 (it seems that ni5660 software uses the niScope on a lower level software ", correct me if I'm wrong). This VI finished, when put online with the 'ni5660 Initialize.vi' and ' ni5660 Close.vi, ' returned the error (-1074135028) with the explanation 'ID attribute not recognized.' "" (The error occurred on the property node in the Subvi "Get the Central frequency")
The goal is to make the action of PXI chassis similar to a HP8563E Spectrum Analyzer. With this in mind, the list of attributes that I will need in the end to set and get (the separate VI) are the following: Center frequency, Span, window, number of Points, resolution bandwidth, level of reference, mitigation and time sweep.
I apologize for my (very probably) simple question, but endless (I only started programming in LabVIEW there about 2 weeks). If someone would be able to point me in how to make apparently PXI-5660 current property settings from thin air, I would be very grateful. If more information or details are needed, feel free to ask.
Thank you

but unfortunately, I'm still at a loss, how to create a VI that "calls" that same property back and the fate, while using only 'VISA In' and 'In Error' as inputs.
Located on how silly that statement. You want to create a function where (for example) you want to set the resolution bandwidth and do not want to pass as a parameter the name of the instrument. You have created the programming language that is able to read minds?
You can use a function where you can pass a parameter in (or use a function that retrieves a parameter) or do nothing at all with the instrument. It is more complicated than that.
There are tutorials available that can help yu with LabVIEW to learn, but I think that there are certain fundamentals means.
Edit: Sorry, I may have misunderstood. to query does not require an entry but I don't understand what you want to query. The parameters of the instrument are all under control stripped - a program you or any other writing. Unlike a GPIB instrument, there is no one '?' command to read a rear frame. It is assumed that you know how the instrument has been configured in the first place.

Get information from a line in a report region to use in conditions
Hello
I have a page with 2 regions.
First region is a report of a table (departments) and the other is another region (employees) report.
One of the columns in the departments report is a link when I click it, it will refresh the second region to view employees by Department.
My problem is when I open the page for the first time or get back into another page, I want to display by default the first Department employees. I don't know how to get that value and assign it to an an element on the Page and use this page point in the second report.
I appreciate all help.
Thank you
andrèseAndrèse
To the question page (that fill you in when the user clicks on the link report Department), write by default as plsqlfunction body and try something like
DECLARE v_dummy tbl_dept.dept_id%TYPE; BEGIN SELECT dept_id INTO v_dummy FROM tbl_dept WHERE ROWNUM = 1; RETURN v_dummy; END;
I guess that you meet dept_id in the page element, when users click the link report Department. You can change it according to your requirement. Also, make sure that the SELECT query matches the Department report query so that the top of your Department report always corresponding with above the results of the SQL query.
Please note that this may not work if your Department report query contains any GROUP BY / ORDER BY / WITH clauses
See you soon,.

Get information from virtual hardware in Web mode
Hello
I have a problem in my workflow Web view.
CPU and RAM to a virtual computer workflow changes.
In an instant, the workflow looks like this:
What I want to do is insert the CPU and the RAM of the current elected VM here:
But I have no idea how do. I hope someone here can help me.
MFG
Patrick
SERVUS Patrick!
You can set "default values" in the presentation of entry of the workflow. (there is no way to include information in the tree-search-browser (from the less any documented way).)
Here you can perform Actions, which returns the current vCPUs and RAM to the virtual machine and fills the value in the input field after selecting the virtual machine.
to do this:
1. create an action that returns the memory (and a second for the number of processors) of a given virtual machine.
2 change the workflow, go to the presentation tab, select the numberCPU input parameter, click on the "Add property" icon in the lower section, select 'default value '.
3 select the fall to the low fields to the symbolized by an arrow (ognl expression) and click on the puzzle on the right icon to select the action. filter for the name of your action, then select the 'VM' input parameter as a parameter for the action
4. the wizard should "make" the appropriate expression of ognl
5. save / finishing
Tips: Think of the Guest OS HAL when switching between 1 and multiple vCPUs and prove the value of memory the user inserts is divisible by 4... (but not orchestrator, vsphere-questions)

Get information from the Bank of Tables HZ
Hi I mostly use CE_BANKS_V for the information of the Bank, but in case I want this HZ_PARTIES table information so how I can get because there is presented data of parties, people, etc.. i don't know which one I should mention to get only the condition information stores.
Kind regards
Shakeel KhanHi Shakeel
If you see the script for ce_banks_v, it uses the table hz_parties only. You can use the following query (this one is taken by the script of ce_banks_v only):
Select * from
hz_parties bankparty, hz_code_assignments bankca
where
bankparty.party_type = "ORGANIZATION".
AND bankca.class_category = 'BANK_INSTITUTION_TYPE. '
AND bankca.class_code IN ('BANK', 'CENTRE')
AND bankca.owner_table_name = 'HZ_PARTIES. '
AND bankca.owner_table_id = bankparty.party_id
AND NVL (bankca.status, 'A') = "A".Thank you

Get information from file name
Hello
I have a somewhat general question, is it possible to extract certain "elements" of a file name?
For example: x 0 xx xxx abc 123 xxxx.avi (or any other type txt, jpg, etc...).
Assuming that the 'abc' is constant throughout the files, but the numbers change (not sequential), can I retrieve just the "abc 123"(ou quelque nombre que ce soit)? "»
I know how the band/build path, but here I don't know what to look for because the distance from the beginning is evolving and the numbers change.
Thank you
