• How to query a Subvi dynamically loaded to its input terminals names?

  Hello

  I have an application where I use dynamically load the Subvi and I need a way to query the Subvi for its names of input terminals.  I'll use several different Subvi now and in the future and will not experience the terminals.

  Any help would be greatly appreciated.

• Problem running Subvi after construction of .exe

  Hi all

  I've seen much related to this topic but you have not found anything specific to my situation.

  I built a simple wrapper to launch different Subvi depending on whether it of Saturday or not.

  The vi works perfectly well as a vi in LV2012. But when I build the application, run two cases-in other words, both Subvi front panels appear and I get a message warning me that I can't run multiple instances of the same Subvi.

  I hope it to be run true or false case and open the correct Subvi once and be done with it. Not sure why both trying to run more than once only after I have build the application. Ideas?

  I thought about it when I went to go back and create a sample project to download for you (which worked fine).

  Has proved to be a mistake in the original specification, I did. I accidentally included the vi in the structure of the case as a source of start-up files. They opened the performance, then we tried to open again after the code that was not allowed due to restrict re-entrant execution, giving me the warning.

  I corrected the issue in new versions by resolving to drink more coffee beforehand.

  Thanks for the support!

• -Run Javascript - dynamic action wait full?

  Hello

  Apex 4.2

  I have a dynamic action that counts two real deposits

  (1) Execute javascript code that calls a plsql process to fill a graphical xml field hidden.

  (2) updates the table.

  The javascript call is made now apparently asynchronously, which means that the table is freshening up before the pl/sql has had time fill the data of chart_xml.

  I understand that some dynamic actions have an option "wait for result" of the execution, but is not available with JavaScript Code execution. I know almost nothing about Javascript, but I guess that this code:

  Apex. Server.Process ('P3_UPDATE_CHART_XML', {}

  F01: $.map ($('[Name="F01"]'), Function (e) {return $(e) .val ()})

  },{

  data type: "text",

  success: function (pData) {}

  });

  Can be adjusted to wait for the pl/sql process to complete?

  Out of my depth.

  Thank you

  Ralph

  Apex. Server.Process is indeed by asynchronous design. Now you can either make the browser wait the result by making it synchronous, or you can define a function sur-succes that run when the call is completed. Going with async, you can define follow-up actions, but "blocks" the browser in the meantime.

  Use the "async" parameter in the 3 param object:

  apex.server.process('P3_UPDATE_CHART_XML',{
  f01:$.map($('[name="f01"]'),function(e){return $(e).val()})
  },{
  async: false,
  dataType:"text",
    success:function(pData){}
  });
  

  Or, since you have the function success there, we can qualify the update region in this chart (but you should give the region to chart a static id) and do not use false async:

  apex.server.process('P3_UPDATE_CHART_XML',{
  f01:$.map($('[name="f01"]'),function(e){return $(e).val()})
  },{
  dataType:"text",
    success:function(pData){ $("#myChartRegionStaticId").trigger("apexrefresh"); }
  });
  

• procedure to run the dynamic DDL

  If I have the T table below, and I need to create partitions based on the year (year), but I need to create partitions for each quarter of the year. How can I write a procedure for this?

  WITH T AS 
  (SELECT 2001 YR FROM DUAL
  UNION ALL SELECT 2002 YR FROM DUAL
  )
  select * From t;
  

  Here is what I have run under the procedure:

  ALTER TABLE T ADD PARTITION (PARTITION P2001_01 VALUES LESS THAN (TO_DATE('2001-01-01', 'YYYY-MM-DD' ));
  ALTER TABLE T ADD PARTITION (PARTITION P2001_02 VALUES LESS THAN (TO_DATE('2001-04-01', 'YYYY-MM-DD' ));
  ALTER TABLE T ADD PARTITION (PARTITION P2001_03 VALUES LESS THAN (TO_DATE('2001-07-01', 'YYYY-MM-DD' ));

  ALTER TABLE T ADD PARTITION (PARTITION P2002_01 VALUES LESS THAN (TO_DATE('2002-01-01', 'YYYY-MM-DD' ));
  ALTER TABLE T ADD PARTITION (PARTITION P2002_02 VALUES LESS THAN (TO_DATE('2002-04-01', 'YYYY-MM-DD' ));

  ALTER TABLE T ADD PARTITION (PARTITION P2002_04 VALUES LESS THAN (TO_DATE('2002-10-01', 'YYYY-MM-DD' ));
  

  What I'm missing here?

  You are 'away' the part where you follow the best practices for the development of pl/sql code that contains dynamic queries:

  1. remove the 'run '.

  2 create the query in a string variable

  3. just to "evacuate" the query as a string

  4. run the query manually to validate one) he did know the correct syntax (yours does not), b) it creates the correct result set and c) it works as expected.

  5. Add the "run" and delete the lines DBMS_OUT.

  If you run this procedure you can easily see what is the problem

  I'm in (SELECT "ALTER TABLE TABLE1 add PARTITION (PARTITION P_' |)") Y.YYYY | '_Q' || Q.Q | ' VALUES LESS (TO_DATE(''' ||). Y.YYYY | '-' || Q.M | '-01''' || ',''' || "(YYYY-MM-DD"' | '))'. XYZ

  FROM (SELECT DISTINCT (TO_CHAR (dt, "YYYY")) YYYY OF TABLE1),

  (SELECT 1 Q, M '01' FROM DUAL

  UNION ALL SELECT 2 Q, M '04' FROM DUAL

  UNION ALL SELECT 3 Q, M '07' FROM DUAL

  (UNION ALL SELECT 4 Q, '10' FROM DUAL M) Q)

  Not even a week, YOU will understand what this request is supposed to look like. And no ONE will be able to reproduce the query or test it.

  v_query_string: = ' SELECT... » ;

  DBMS_OUTPUT. Put_line (v_query_string); -Now you can actually SEE what query is used and test it manually

  BECAUSE me in v_query_string

  Once 'v_query_string' does not add the actual as a comment in the code query so that later there's someone test with a real query.

  	LOOP
  	v_alterstring: = i.xyz;
  	EXECUTE IMMEDIATE v_alterstring;
  	END LOOP;

  This code DOES not yet - it until it works:

  LOOP

  DBMS_OUTPUT. Put_line (i.xyz); -run and test manually

  -I.xyz EXECUTE IMMEDIATE.  -NO. - not until you have executed and tested manuallyl queries

  END LOOP;

  Same here - a time that the code works adds at least ONE query real to the code as a comment, so that someone looking at the code knows what applications should actually look like.

• Why the letter spacing is ignored when running in dynamic text fields?

  I use dynamic text fields using the font Arial embeded in Flash 8 on Windows XP and when I set the letter spacing of 5, then run it film the spacing is lost. Tried with several other fonts and they always lose their spacing during execution.
  
  Why is this?
  
  Kevin

  it solved!

  You must reset the value linespacing in code after you put text, as follows:

  var my_fmt:TextFormat = new TextFormat() / used to change the color of the text
  Label.Text = "" Hello World ""
  my_fmt.letterSpacing = 1
  label.setTextFormat (my_fmt)

  You are approaching this the wrong way.  Create an external table based on the file.  External tables are CSV, fixed width data in a queryable table.

  You will need to create an oracle directory to put the file in (MY_ORA_DIR) I leave it for you to do, and then perform the following...

  create table BASELINE)

  ITEM_ID varchar2 (32)

  )

  EXTERNAL ORGANIZATION

  (

  TYPE ORACLE_LOADER

  THE DEFAULT DIRECTORY MY_ORA_DIR

  ACCESS SETTINGS

  (

  RECORDS DELIMITED BY NEWLINE

  LOGFILE "dinput.log".

  BADFILE "dinput.bad."

  NODISCARDFILE

  FIELDS

  (

  ITEM_ID

  )

  )

  LOCATION ("dinput.txt")

  )

  REJECT LIMIT UNLIMITED

  /

  All the dubious records appear in dinput.bad. Dinput.log will give you information.

  External tables are read-only, so once you set up your file, you can create editable as a normal table.

  create table ITABLE_EDITABLE as

  Select * from BASELINE

  /

• How to get the Subvi (the virtual path is in .exe) reference in Run Time System

  Hello world

  The problem is how to get the reference of the Sub - VI in run time system, when the Subvi is in .exe after construction.

  More details:

  Top of page vi called the Subvi dynamically, so that the Subvi is always included, and the source object is the application.exe.

  After the above configuration, the Sub - VI will be the application.exe. For example, the path of Subvi est...\application.exe\SubVI.vi

  So, how to get the reference of the Subvi in Run Time System?

  I can't do it when you use 'open reference VI' with le...\application.exe\SubVI.vi path in the run time system.

  In fact, I can create a file to include the Subvi, rather than build the Subvi in application.exe, then I can get the convenintly reference. But this isn't my favourate average.

  Thank you

  chenyin

  That is the problem. Call a Subvi dynamic means users could change, but it is also very attractive.

  The dynamic call should be used in a user control, but some parade can avoid problems.

  It depends on why you use dynamic calls...-online 2 main ways:

  -Dynamic call are used to maintain a scalable framework for the code without acting on the executable file-online a single VI distribution managed by the administrator/developer

  -Dynamic call are used to provide a collection of "external" characteristic that could be enriched by the administrator/developer. For example, you provide your customers a set of selectable custom signal filters in the executable.

  In 2 cases, you are only able to assess the skills of the users to know if there is a risk of damage, if there is a change.

  So to stay only master a parade might be to provide dynamic VI without a schema, but with the problem of maintenance, since no in-place editing and more attention to manage distribution.

  Another way is to hide the actual distribution to user-online call dynamic VI but it without name as *.vi but others (a repellent name as system of OS name ) or simply without extension in order to attract not user... but that's debatable...

  Another more difficult but more secure method is to create a consistency check before your routine (version, user, modified date,...)

• Showing the façade unqiue for several instances of appeal Subvi

  Hello

  I have a Subvi, which resembles a table 2D data and graphs of the plots.  I call the Subvi and he opens the subVIs Panel to display plots.  Now I would like to put the Subvi in one for a loop and call several times with various 2D charts.  I'm trying to figure out how to make multiple instances of the Subvi front panel appear. Essentially a front for each table 2D.  All I can get it to do is to open and close the user interface for each Subvi call and for the last table display the user interface for the data.

  I tried to make the VI reentrant and selected the option pre allocate the memory for each clone.  Maybe it works, but I need the front of each Subvi call to stay open.

  Thank you

  Gary

  Thank you both for the help.  I used the open VI of reference and call by reference and created a strictly typed reference VI to call the Subvi dynamically.  Is attached a screenshot of the block diagram.  The link below has guided me to created the strictly typed VI reference required by the "reference" entry of the reference function call.

• Load a dynamic VI and keep in memory after execution

  Hi guys,.

  I use a strange setting that I have to follow a set of rules.

  My problem is the following:

  I have a main VI (which is compiled into an EXE file) that dynamically loads and executes a Subvi (the Subvi is not compiled into the EXE file). Calls Subvi has overall functional which is called only by dynamic screws, where the global is not a dependency of handmade VI and it is not compiled into the EXE file either. As you can see already, when I call my Subvi dynamic for the first time (for example it behaves like a SET function), it will define the functional global; then, when the dynamic Subvi execution stops, it releases the global functional VI. So if I call another sub - VI dynamic as a function of READING, he will not retain the information specified by SET Subvi.

  I'm not allowed to do the subVIs or global one functional dependence of handmade VI and it can not be compiled into the EXE file, so what I have to do is load the Subvi Dynamics somehow and either keep in memory even when the execution ends, or keep the functional global in memory after the first call.

  Anyone know how I would be able to do this?

  Help is appreciated,

  Drazen

  Drazen,

  When ' a VI dynamic calls functional overall for the first time, launch an another dynamic VI (Holder.vi) who has the functional overall as a Subvi.  Holder.VI does nothing except wait until the hand VI is called dynamic screws as long as Holder.vi is in memory, it will also keep the functional global in memory.

  I have not tried this, but think that it will work.  It of a little awkward, but must have a minimum size and impact on CPU resources.

  Hi MarkBerri,

  ·         How long have you been faced with this problem?

  ·         Did you do changes on the computer before the show?

  Svchost.exe is a process name generic host for services that run from dynamic link (dll) libraries. The Svchost.exe file is located in the folder C:\Windows\System32. At startup, Svchost.exe checks the registry services part in order to build a list of services that it needs to load. Multiple instances of Svchost.exe can run at the same time. Each Svchost.exe session can contain a grouping of services. Therefore, separate services can run, depending on how and where Svchost.exe is started. This grouping of services enabling better control and easier debugging.

  Svchost.exe groups are identified in the following registry key:

  HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\Svchost
