  Narendra,

  Two characters can type cast into a uint16 you VI supports.

  To summarize. Take one (4 bytes). Flatten it to a string (4-byte) divided this string into two parts of 2 bytes each. Cast in u16 (16 x 2 = 32-bit).

  However, if you really want to follow the IEEE standards then you will need refer this KB. His is not that simple, but seems closer to what you are looking for.

• How can I write the trigger for the global temporary Table

  Hi Grus,
  How can I write the trigger for the global temporary Table.
  
  I created the TWG with trigger using the script below.
  
  
  CREATE A GLOBAL_TEMP GLOBAL TEMPORARY TABLE
  (
  EMP_C_NAME VARCHAR2 (20 BYTE)
  )
  ON COMMIT PRESERVE ROWS;
  
  
  CREATE OR REPLACE TRIGGER TRI_GLOBAL_TEMP
  BEFORE DELETE, UPDATE OR INSERT
  ON GLOBAL_TEMP
  REFERRING AGAIN AS NINE OLD AND OLD
  FOR EACH LINE
  BEGIN
  INSERT INTO VALUES EMPNAME (: OLD.) EMP_C_NAME);
  END;
  /
  
  
  trigger was created successfully, but her would not insert EMPNAME Table...
  
  Please guide if mistaken or not? If not wanting to give a correct syntax with example
  
  
  Thanks in advance,
  Arun M M

  BEGIN
  INSERT INTO EMPNAME VALUES (:OLD.EMP_C_NAME);
  END;
  

  you are referencing old value in insert stmt.
  
  BEGIN
  INSERT INTO EMPNAME VALUES (:new.EMP_C_NAME);
  END;
  

  then run your app, it works very well...

  CREATE GLOBAL TEMPORARY TABLE GLOBAL_TEMP

  )
  ON COMMIT PRESERVE ROWS;
  
  CREATE OR REPLACE TRIGGER TRI_GLOBAL_TEMP

  INSERT INTO EMPNAME VALUES (:new.EMP_C_NAME);
  dbms_output.put_line(:OLD.EMP_C_NAME);
  END;
  /
  
  create table EMPNAME as select * from GLOBAL_TEMP where 1=2
  
  insert into GLOBAL_TEMP values('fgfdgd');
  commit;
  select * from GLOBAL_TEMP;

• How can I set the graph on the Panel like buttons?

  Hi all

  I'm trying to control a camera by sending control signals and receive signals from IT. After I take a picture and display it on the screen, I want to put it in the form of an array of bool 2D controls. While I can click on some pixels, to send the next control of the signals that are for addresses. I also want to perform a zoom in and zoom back functions, by which I can clearly see the pixels (buttons). I can only implemented in LabVIEW? If I build a table 2D buttons, I can't get rid of the spaces between the buttons. I'm using LabVIEW 8.5. Any suggestion will be appreciated.

  Best wishes

  Bo

  I'm not clear on what the 2D Boolean table has to do with a photo.

  If you have a photo and when you click on the image means something.  You can use an image control.  Use a mouse on this image event.  Use the mouse coordinates to determine where the image was clicked.

• How can I write the SQL for this result?

  Hello my dear,
  Here first of all the script.

  CREATE TABLE ACC_TEST(
  AD_ID NUMBER,
  AD_NAME VARCHAR2(50),
  AD_SPM_ID NUMBER);
  /

  the data are

  Insert into ACC_TEST (AD_ID,AD_NAME,AD_SPM_ID) values (136,'Saleh Ahmed',129);
  Insert into ACC_TEST (AD_ID,AD_NAME,AD_SPM_ID) values (142,'Hamidur Rahman',136);

  INSERT INTO ACC_TEST (AD_ID,AD_NAME,AD_SPM_ID) VALUES (129,'Sazib',124);

  I need the following result, when passing a value of Ad_Id. For example I go to 142 then result must be

  Select Ad_Id,Ad_Name
  From..
  ...
  where ad_id=142
  
  Ad_Id   Ad_Name

  Guess luck. Guessing is generally not the best way to solve problems. It is generally faster and more reliable to say exactly what you want, as well as give an example.

  fallen little more that I want to know, if I want to restrict the output not more then 2, which would be sql?

  Now, you're not even giving for example!
  Maybe you want something like this:

  SELECT     ad_id
  ,     ad_name
  FROM     acc_test
  WHERE     LEVEL     BETWEEN 2 AND 3          -- Changed
  START WITH     ad_id     = :target_ad_id
  CONNECT BY     ad_id     = PRIOR ad_spm_id
  ;
  

  which will show just the mother and grandmother of the given line.

  I work with the developer of forms a lot. Knowledge of SQL is like sql oracle (9i cerfitication) book. But this type of sql is not available here.
  where can I learn this type of sql? SQL different then regular?

  Certification is another matter entirely.
  There are books and web sites dealing with more advanced techniques. Sorry, I don't know any good enough to recommend. Some authors (such as Tom Kyte) are always good.

  Here are a few sites that explain CONNECT BY queries:

  Hi, Emmanuel.

  Welcome to the forum!

  Here's a way to do what you asked:

  SELECT       doc_id
  FROM       table_x
  GROUP BY  doc_id
  HAVING       SUM (CASE WHEN name = 'execno' AND value = '000004'  THEN 1 END) > 0
  AND       SUM (CASE WHEN name = 'step'   AND value = '400'     THEN 1 END) > 0
  AND       SUM (CASE WHEN name = 'scna'   AND value = 'cd_demo' THEN 1 END) > 0
  AND       SUM (CASE WHEN name = 'system' AND value = 'd47-010' THEN 1 END) > 0
  AND       SUM (CASE WHEN name = 'type'   AND value = 'step'    THEN 1 END) > 0
  ;
  

  If you think that a WHERE clause would be used, but WHERE does apply to a single line. You need a condition that checks several rows in the same group.
  WHEN has an effect something like WHERE.

• How can I write the symbol ' greater than or equal to "in a string or a label?

  Hello

  I tried to use the "symbol" font to create the greater or equal symbol, but it does not work.

  Does anyone know how to do this?

  Thank you

  User

  The only way I know to do, is to type in the appropriate character code (Alt-0179, using the keypad), then highlighting the unique character (in most fonts, it is the exponent 3), then change the font to "symbol".  The rest of the characters in the string will be in the same font as before, only the highlighted character will change.

• substr? How can I retrieve the codes that are only 6 characters

  I have this request
  

   
  SELECT 
  distinct
  SUBSTR(A.STVSBGI_CODE,1,6),
  SUBSTR(B.STVSBGI_CODE,1,6),
  A.STVSBGI_TYPE_IND,

  AND B.STVSBGI_TYPE_IND = 'C'
  AND instr(A.STVSBGI_CODE,1,6) =  instr(B.STVSBGI_CODE,1,6)
   

  I want to be able to extract ONLY the values (STVSBGI_CODE) where the SUBSTR (A.STVSBGI_CODE, 1, 6).
  There are codes in the tables of 4 characters, the query gives me 4-6 characters...
  How can I write the query to get the 6-character codes
  Thank yoou

  Hello

  If you want to only include lines in the output, if the code is at least 6 characters?
  Add to the WHERE clause:

  AND     LENGTH (a.stvsbgi_code)     >= 6
  

  It doesn't matter if you use a. stvsbgi_code and b. stvsbgi_code in this State; the join condition is already excluding the lines where it is less than 6 characters but the other is not.

  I hope that answers your question.
  If not, post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all tables and also post the results desired from these data.
  Explain, using specific examples, how you get these results from these data.
  Always tell what version of Oracle you are using.

• How can you write a time interval in the timer for User Interface?

  Use a timer on a control panel, that triggers a callback function to the sample data.  I would like to read a digital input from the user interface panel and then set this value in the interval of the timer.  But how do you write the interval of timer?  Obvious function doesn't seem to work,

  SetCtrlVal (panelHandle, PANEL_TIMER, %SAMPLESECONDS%);

  Probably the best place to start is with the help of high level for the control that you are interested in.   I usually just to go to the index tab in help, start typing the name of the control (timer in this case) and then choose the top level help topic.  From here, you can see the attributes that you can use the events you can capture, programming concepts, etc.

• How can I know the exact date of the csrss.exe download?

  HelloW please someone tell me how can I know the exact date of the download or installation of csrss on my pc. in the properties of the box, I can only find an old date (date of creation 2009) but think I didn t have this pc so... Please help me

  Hello

  Thanks for posting your query in Microsoft Community.

  I understand that you have questions about the date of download csrss.exe.

  But I would like to know more information, to help you better.

  (1) get any error message related to this csrss.exe process?

  (2) what is the problem in the computer?

  In the meantime, please refer to the below suggestion.

  In fact, the csrss.exe is not a program that can be downloaded, it is rather a process in the Windows System. Thus, it would display the date of creation as the process is being created. Csrss.exe is a system process that is needed for your PC to function properly. It should not be deleted.

  The Microsoft Client Server Runtime Server subsystem uses the csrss.exe. This process of management of the majority of the graphical instruction sets under the Microsoft Windows operating system. As such Csrss.exe offers the important functions of the operating system, and the Blue Screen of Death displayed may lead to his termination.

  Csrss.exe threading and features of Win32 console window controls. Threading is where the application itself is divided into several simultaneous running tasks. Threads supported by csrss.exe are different
  process in this son are usually included in the process, with different threads, sharing of resources within the same process. The Win32 console is plain text window in the Windows API system (programs can use the console without the need for display of the image).

• What is READ the array returned by the DAQmx meter? How can I know the two functions DAQmx READ data stream in the same WHILE loop?

  I have a question about the order of execution.  In the WHILE loop, I have two things to measure, period and tension using the DAQmx READ functions for voltage and the meter.  In the end, I want to collect these data as points almost simultaneously as possible, as a pair and then send them together to another piece of code (not shown here) which them will result in some sort of command for an engine.  It would be run, and then I want to perceive the tension and the period at a time later and do the same thing.

  (1.) I'm a little confused on what the meter of the READ function is back because it's a table.  What is a picture of?  I thought that it was up to the value of the individual periods between rising edges.  The output of the counter 1 DBL d's a table. How many elements in this table, and what determines the size of this table?  Are the elements of the array the individual delays between the edges?  How many values are stored in the array by executing?   We take the AVERAGE of the last 15 items, but do not know if we are throwing some of the data or what.  How to understand the composition of this painting?  How can I change the composition of this painting?  Is it possible to measure only one period at a time, for example the time between TWO edges?

  2.) Will this WHILE loop execute as it gathers tension and a "period table ' (remains to be understood by me) by TIME running in a loop?  In particular, we want that the value of the tension associated with the value of the AVERAGE of the period "array", so we can use two data items to create orders of next control every time that the two values are reported.  The structure for the delivery of vi will be attached data in pairs like this?  I understand that one of the READING functions run not before the other function of READING in the WHILE loop.  I want that the period "means" and "strain (Volt) collected at the same pace. This vi will he?

  Thank you

  Hi David,

  I suggest including the DAQmx Start Task function. If it does not start before the loop, it starts the loop and work very well, but it is not as fast and efficient. In the model of task status, task wiill go to run the checked each iteration of the loop and then back the time checked running when it restarts.

  The status of the task model: http://zone.ni.com/reference/en-XX/help/370466V-01/mxcncpts/taskstatemodel/

• How can I get the data view to display the same amount of time I save?

  I use the Sound and Vibration Measurement Suite.  In the data view, I display a graph of time, the power spectrum, the Color Map and the waterfall.  I am also showing strength in numbers group for several bands and doing cutting-edge research.  I record 100 ms of the transient wave.  In the data view, why the temporal plots show several seconds of data?  What determines how much time will appear in the data view?  More important, the power spectrum reflects the power for the entire of several seconds of data displayed?  Same question for power in the values of band and cutting-edge research.  I want to just this data displayed for 100 ms of the wave that I record.  So, how can I get the data displayed (waveforms) and power numbers come only 100 ms of the recorded wave?

  Finally, what is the best way to make account concisely the recorded data?  By slide numbers on the Documentation tab is not concise, because it comes with graphics, etc..  I tried save as ASCII/LVM, but I get a bunch of stuff intermiated I don't care.  Help?

  Hi TimRsandiego,

  SignalExpress is programmed to display graphs with default scales based on the type of action, it's reading. These scales and settings can be changed by right-clicking on the graph, and then select Properties.

  If you are interested to learn more about how to use SignalExpress, I would recommend checking out some demonstrations/tutorials on NI.com. You can find some of these demos at the following location:

  Let me know if you have any other questions.
