• How to check if a node exists in the XML file?

  I was asked to program a method to import data from xml files in our Coldfusion 8 Web site, I am new to the use of XML.

  My method worked however I encountered the following error:

  Element NETWORKORDER. SECONDARYADDRESS. CONTACTNAME is undefined in MYDOC.

  Investigation on the node in the XML file was not present.

  Is there a method I can use to resolve this error by checking if a node exists in the xml file, which works with my current code below?

  Since you already have the XML parsed in a document, the easiest is to use xmlSearch(). Take a look at the doc, it is pretty easy to use. Something as simple as:

  To the most complex as:

  And in both cases:

  Read the doc and google is your friend "coldfusion xmlsearch.

• Check if e-mail exist in the database table

  I stumbled on this a few times before, but I'm not familiar with this system, whenever you enter an emailaddress, you see as a clock indicating the system checks if the e-mail address may be used, in other words, is not yet in a table. I would like something similar and when the "audit" is done and the emailaddress is not in the DB table, the rest of the form appears, otherwise, an error message indicates the address is already in use. I guess this could be done using Javascript, but is there also a PHP way to do this?

  It's simple to achieve. Create a query that filters your e-mail address in the database table WHERE = POST of the email field in the form is sent. If the query returns a line then the email already exist, otherwise it is available and can treat the rest of the form.

• How to check if utl_file was used in the database with the n ° / limited audit

  How can you check the database to see if any user has used the UTL_FILE pacakge?
  
  Thank you

  Another angle based priv study's directory objects. Read and write access to a directory object is necessary so UTL_FILE work. If some patterns have a write access to the directory objects, can create files.

  A schema that has the priv to create any directory has full access to create any necessary directory object.

  This, along with the methods suggested above, will restrict just what patterns have code and the privs required to use UTL_FILE successfully.

  If the code has been dynamic PL/SQL (an anonymous block), then who does identify actual code executed UTL_FILE, very difficult.

  EXISTS checks for the existence of an element, not a value. Since you're using VARRAY (btw, it is not recommended), your only choice is a loop through:

  SQL> DECLARE
    2       TYPE dnames_var IS VARRAY(7) OF VARCHAR2(30);
    3       dept_names dnames_var := dnames_var('Shipping','Sales','Finance','Payroll');
    4  BEGIN
    5      for i in 1..dept_names.count loop
    6        if dept_names(i) = 'Shipping'
    7          then
    8            dbms_output.put_line('Exists ................');
    9            exit;
   10        end if;

   12  END;
   13  /
  Exists ................
  
  PL/SQL procedure successfully completed.

• How can I check if a file exists in the CVI real-time?

  Also, it would be nice if designated so help file functions have been supported in real time or now.

  I tried this:

  If (GetFileAttrs (DataFileName, NULL, NULL, NULL, NULL) == - 1).

  You can check if a file exists in the CVI real-time using GetFileInfo.

  CVI provides a list of the available functions in the CVI real-time here: CVI real-time functions

• Check if values exist in the database

  Hello

  I have problem with values that are not in the database.

  I have a form, and there are two types of users: normal and Admins.

  If the user is normal, it can not access anyone else entered the database. But the administrator can access all entries.

  I did a check in so that the normal user can only access its entries:

  < cfif NOT session. Admin AND process.addedBy NEQ #session. AccountID # >
  < cflocation url = "main.cfm" addtoken = "no" > "
  < cfelse >

  <! - rest of the form - >

  By these, a normal useer cannot access all entries other than his own.

  But for admin, an administrator can access all entries, but not the entries that are not in the database. The query bound to the form is:

  < cfquery name = "xx" datasource = "yy" >
  Select Properties entryid, addedBy, deletedBy processedBy
  Of yy
  where entryid = #URL.entryid # AND processedBy IS NULL AND deletedBy IS NULL
  < cfif NOT session. Admin > AND addedBy = #Session.AccountID #.
  < / cfif >
  So both users can access the respective entries, but when the administrator between an entryid in the URL doesn't exist not in the database, do not the page back to the home page, it shows rather the form.

  So my question is how to avoid the values not in the database.

  Thanks for the help.

  How can I set up Vista so that the PC does not switch to another window (for example the Spy Sweeper alerts) while I am playing a game?

  Vista is not in control of this technique. Spy Sweeper needs to have an option to control that. If this isn't the case, then it is badly programmed. Flight of focus (go to another window) when it is actually needed is a big no-no for the design. I find this option, if I were you :)

• How do I run a script only if the field is not empty

  How do I run a script only if the field is not empty

  Well well, thanks to you, I had a full date on separate days, the months and the years in different areas. But now, I have a problem, as PDF has several fields calculated with script if you enter the date calculated by all other areas, which have separated and undefinied gives me does not want to put this to not always use this field. I tried to put one conditional if else but I sale. Esto, this is what I'm wearing

  var datesol = event.value;//declaramos the variable

  If (datesol = "") {}

  this.getField('yearsol').value = "";

  this.getField('monthsol').value = "";

  this.getField('daysol').value = ""}

  else {}

  var array_datesol = datesol.split("/"); / / separamos esa con date the split funcio

  this.getField('yearsol').value = array_datesol [2];

  this.getField('monthsol').value = array_datesol [1];

  this.getField('daysol').value = array_datesol [0];

  With what they do not separate them now.

  Help please

  As mentioned, you cannot use

  If (datesol = "")

  because that sets the value of datesol to «» (you will need to double for the comparison operator =)

  If you want to run code only if it is NOT empty, while it takes:

  If (datesol <> "")

• How to find if a table exists in a particular backup?

  Hi Experts,

  Sorry, above is not possible. My bad,

  You can use below,

• How to check if a file exists?

  Hi guys.

  I am running javascript in Acrobat .pdf file created in LiveCycle Designer.

  I need to check in silence if an external file outside the open document (C:\something\something\something.pdf) exists or not.

  I understand that I'm only able to do this as a function of confidence within a script to the folder level javascript.  I am familiar with those.   The problem is, I don't know what function I should use and will have a difficult time in the research on it.

  Try to use: doc.exists?

  Try to open the document with a function and catch the error if the file does not exist?

  I'm not so sure that if I just spend my path as a string, say "/ C/Something/something/something.pdf" or if I should first deal with the file as an object like:

  var myFile = new File("/C/Something/something/something.pdf") (which was not in Acrobat... don't try to run it as a function of confidence)

  Please notify.

  Thank you!

  I finished this figure myself.

  XFA/JavaScript in my paper, I call a custom function that I have written and pass a string (or a string variable containing) my file path for that I would like to check:

  if(typeof(MJS_FileExists) == "function") {
      try {
          if(MJS_FileExists("/C/something/somethingelse/filetocheckfor.pdf") == true) {
              xfa.host.messageBox("file is there");
          } else {
              xfa.host.messageBox("file is NOT there");
          }
      }
      catch(e) {
          app.alert("Processing error: "+e)
      }
  }
  

  The function I call is a folder level javascript.   You have to maybe do some Googleing on how and where to install them.   In the my file .js file real javascript level where the function is housed I use:

  var MJS_FileExists = app.trustedFunction(function(filename) {
      app.beginPriv();
      var existingDoc = false;
      try {
           var checkDoc = app.openDoc(filename);
           checkDoc.closeDoc();
       existingDoc = true;
      } catch(e) {
       existingDoc = false;
      }
      return existingDoc;
      app.endPriv();
  });
  

  It took me a lot of trial and error.  It sucks there is not a lot of in on the internet on how to do it via Acrobat / Live Cycle.   Hope this helps someone else.

• How to check if a folder exists

  Hello
  
  I have a custom filter component:

  public class BarcodeMetadataFilter implements FilterImplementor{
  }

  I check here if the file exists in xCollectionId value, so I have two qustions:
  
  (1) should what service I call to check if the file exists?
  (2) how to call this service from the filter?
  
  Kuba

  Call a service such as COLLECTION_GET_INFO. Pass the parameter dCollectionID which must be xCollectionID. If you receive and error, it may mean that the folder does not exist. You should check the error (exception) to ensure what he wants to say to you is that the folder does not exist.
