• Example of tree area

  Hello
  
  I use my apex.oracle.com workspace. I am creating a region of the tree using the emp table. I use the typical Wizard but when I run the page in the tree is not displayed.
  
  This is the query that is generated by the apex with the wizard.
  
  Select case when connect_by_isleaf = 1 then 0
  When level = 1 then 1
  of another-1
  end the status,
  level,
  'ENAME' as the title,
  NULL as an icon,
  'EMPNO' as value,
  NULL as ToolTip,
  NULL as link
  of ' #OWNER # '. " EMP.
  Start by "MGR" is nothing
  connect prior "EMPNO" = "MGR".
  siblings arrested by 'ENAME '.

  Run the page: works fine - no errors.

  Run SQL workshop:

  No data found.

  Very well. Then of course the bound data.

  select * from emp
  

  16 rows returned

  Large.

  Connect to start with the clause:

  start with "MGR" is null
  

  Oops. No record where "MGR" is null. Not a tree!

  For a basic on trees tutorial, see:

  [Objectives and accessors trees | http://www.oracle.com/technology/oramag/oracle/09-jul/o49frame.html]

  This specific example is something a little more complicated to ensure that lines which are parents of rows that meet the filter clause is also included in the query. Unfortunately I have no other documents available on this demo.

• Ext tree images

  Hello
  I'm trying to implement example of tree of Tobias (http://apex.oracle.com/pls/otn/f?p=65555:38) but I'm having a problem get the images folder/sheet is displayed.) I know it's probably something stupid I'm missing, but I can't understand it. I have the following line in my .js file:
  

  Ext.BLANK_IMAGE_URL = '/i/custom/ExtJS/resources/default/tree/blank.gif';

  And I made sure the path to the images in the file ext - all.css was correct. When I run the page, the images in the tree are all empty. When I remove the line above my .js file, the pictures in the folder and the leaves appear, but blank.gif image does not (obviously). So I don't think it's a matter of my image path err, but when the Ext.BLANK_IMAGE_URL is set, it's like folder/sheet images do not exist.
  
  Any ideas?
  Thank you!
  Tammy

  Hi Tammy

  You get further and further the right answer.

  First, you must copy all of the Ext files on your web server, keeping the structure of folders.
  The file ext - all.css uses relative paths to reference images, so you have to keep the existing structures of the file.

  Second, the solution of Ext.BLANK_IMAGE_URL I have given is correct and must come before the code for your tree

  i.e.

  Ext.onReady(function() {
     Ext.BLANK_IMAGE_URL = '/i/1px_trans.gif';
  
     // your tree code
  });

• Hall effect sensor

  Hello

  I use a 90217 Melexis Hall effect sensor and magnet to measure the speed of ROTATION of an axis of rotation.  I have developed a VI in LabVIEW for this purpose.  It measures the speed of the rotation axis with precision up to 600 rpm.  The problem I have is that whenever I have to turn the shaft at a speed higher than 600 rpm, all measures of my VI is 600 rpm.  For example, the tree turned to 1100 rpm and all that he read was 600 rpm.  I tried to fix this by multiplying my rpm of reading by a factor of 2, and I had always a 1080 RPM reading when my tree turned to 1100 RPM.  However, I wanted to know if there is an error in logic that I used for my VI.  Thank you.

  Hi SS1,.

  two points:

  (1) your inner loop is not necessary:

  

  Use rather math table...

  (2) sampling frequency is set at 1000 Hz. According to Mr. Nyquist your highest possible signal frequency is 500 Hz (in theory). You are limited by the sampling frequency...

• VI for registration of remote OPC servers?

  We use the engine tag DSC for save data from different remote OPC servers. DSC requires these OPC servers to be registered before connect you to them. To do this, we open the tag Configuration Editor and choose SERVER > BROWSE NETOWRK OPC SERVERS in the menu.

  This set works well... but now, we want to automate the process. Is there a screw that we can use to register the remote OPC servers? As usual, I tried to search in the vi.lib\lvdsc folder, but I could not find what I'm looking for.

  Is this possible?

  I guess it is to add a few touches the registry or DATABASE file. Maybe we can build a VI that add some keys in the registry? Any tips?

  John Paul,

  All the used and registered remote server for LabVIEW DSC OPC are stored in the registry as you may have guessed. When you know exactly this registry stettings, you could create a LabVIEW VI with the register screw who writes specific keys in your registry.

  What to write to what key?
  1. search on the remote computer recording for the OPC server. You can find it under HKEY_CLASSES_ROOT\ for example, under
  HKEY_CLASSES_ROOT\National Instruments.OPCFieldPoint is a mutual FUND of NI Fieldpoint server.

  2. go to your computer where you want to save the remote OPC Server
  HKEY_LOCAL_MACHINE\SOFTWARE\National Instruments\LabVIEW DSC\Remote OPC servers
  This is for DSC LV stored remote OPC servers. If the \Remote OPC servers is not the equipment you could generate this key. (just with default data folder)

  3. Add keys to own because it would be created by the GUI of TCE interface. Basically, you need to copy the same keys (OPC, CLSID, OPC\Vendor server name) as you found them at the point 1. the key to servers remote OPC with the difference that you add the computer name before the name of the server in square brackets.
  For example, the tree would look like:
  HKEY_LOCAL_MACHINE\SOFTWARE\National Instruments\LabVIEW DSC\Remote OPC servers
  ------(ComputerName) OPCServerName
  \CLSID
  \OPC
  \Vendor

  The key data are the same settings of REG_SZ data found in 1.

  If you need to register some of the servers remotely on multiple computers that I would recommend to export GUI TCE generated key via the regedit.exe and import it on any computer that would connect to the same remote OPC server.
  If you want to automate the importation without the user interface of regedit.exe, you can call in a prompt, regedit.exe/i/s. E.g. regedit.exe/i/s c:\temp\Remote OPC for LV DSC.reg

  DSC in the DATABASE file stores only the VI, proxies and servers IAK (obsolete).

  Hope this helps
  Roland

  PS: Since it is manually facts and National Instruments does not provide documented APIs or screws to do such things - currently, it is recommended to use GUI TCE to register remote OPC servers-, it can not be guaranteed that this describes the procedure would work for the latest or other versions of LabVIEW DSC.

• Creation of several indexes of the columns of same

• APEX 4.0 Substitutions

  Hello
  
  I am a student because the transition from Oracle Forms to APEX for my business. One aspect that we will need made use of navigation trees to navigate between the pages.
  
  I tried to follow an example of the book Pro Oracle Application Express (3.2), but I always get an error on navigation. Error message: error ERR-7620 unable to determine workspace for application (). seems to be the result of the use of the substitution of APP_ID. My URL is read from a database table and is in the form of: f? p = & APP_ID.:2: & SESSION. If I swap & APP_ID. for 100001 displays the page (but I wonder you connect once more). If I create a display one item and assign the substitution APP_ID element, the value appears correctly (assuming that I go as far as the display of the page).
  
  I've hunted high and low but have not been able to determine where I am wrong.
  
  No matter who would be kind enough to point me in the direction of a possible solution to an APEX worked example navigation tree?
  
  Thank you in advance,
  
  Danny

  Hello

  You should only store the id of table page.
  Then build URLS in Apex, using substitution strings and concatenate the table as page IDs

  SELECT col1 id,
    col2 pid,
    col3 name
    'f?p=&APP_ID.:' || col4 || ':&APP_SESSION.' link
    NULL a1,
    NULL a2
  FROM my_link_table
  

  I think that substitution do not work if you really URLS as below table

  f? p = & APP_ID.: 2: & SESSION.

• RH7 to 7.02 update

  Hi all
  
  I migrated my projects help to a new PC, uninstall (and disable) my copy of RH7 on my old PC and installation and activation on the new PC. I noticed that a few things weren't quite right (example of tree, try to insert an image and I can't navigate and select this option, I have to enter the full path in). Then I remembered that the patch for 7.02 is released last year, then I tried to update (in the menu help-> updates...) and I got the following error:
  
  Adobe Updater
  -Adobe install Update Manager
  -Adobe Updater
  You are taken to a download, but the file on the server has changed.
  
  He then does not allow me to update RH7. Does anyone know how to fix this?
  
  Kind regards

  Try to download patches from here.

• Apex to Apex 4.0 3.2 upgrade problem.

  Hello
  
  until yesterday, I worked with APEX 3.2 (database 10g on Windows XP Pro SP3).
  But administrators have upgraded to APEX 4.0 last night (I have been informed that a few hours before).
  
  So this morning, I try to familiarize with APEX 4.0. She looks cool, but I have a problem... my application is no longer functional.
  
  When I try to navigate using the tabs, I get:
  Error: apex is not defined
  
  When I try to validate a form, login, etc. (buttons), I get:
  Error: html_GetElement is not defined
  
  When I try to click on the link "Show link Edit" in the menu of the apex, I get:
  Error: Quick links is not defined
  
  When I try to click the little button to change each element on the page of the ti, I get:
  Error: popupURL is not defined
  
  When I try to click on a label with the help, I get:
  Error: popupFieldHelp is not defined
  
  ...
  
  and for example, my tree (built with my own javascript function) does not appear.
  
  You have an idea of what may cause this?
  
  Thank you.
  
  Yann.

  Yann,

  Looks like your DBA has not load the images directory and now you are missing several javascripts and icons and images...

  Tell them to read the installation instructions, especially the chapter on the images directory (/ i /).
