What is the equivalent of key() in php here?

In actionscript which is equivalent to key in php which States that:

Le Key() function simply returns the key of the array element that is currently being pointed to by the internal pointer. It does not move the pointer in some way. If internal pointer points beyond the end of the elements list or the array is empty, key() returns NULL .

more can be seen here:

http://PHP.net/manual/en/function.key.php

for an array, you must use the indexOf() method.

var int index = yourarray.indexOf (yourarrayelement);

but for an associative array (= object), you can use:

function keyF(obj:Object,e:*):String {}

for (var s:String in obj) {}

{if(obj[s]==e)}

return s;

}

    What is the unique sort key in vbscript?

    RRR OK. Imagine that you have a list of people which contains the full name and address of each person, amongst others, and that you want to search for a certain person.

    Now, if you are only looking for the name, something like. Now you use a multi key to get the right person consisting of 2 fields name & address.

    It's the same thing with sorting it will begins the list of all the names people AND say something like:

    L1 A1

  • In Gimp, there is a command called "alpha to selection". Who selects the alpha channel only. What is the equivalent command in Photoshop?

    Untitled.jpeg In Gimp, there is a command called "alpha to selection" which automatically selects the alpha channel of the image or layer. What is the equivalent command that in Photoshop? I tried Googling it but everything that comes is tutorials on masks. I just want to know what to select the alpha automatically without using a 'magic wand' to select one by one.

    CMD (mac) or Ctrl (pc), click on everything that has transparency and that load a selection. This includes layers with transparency, masks layers, channels and paths. Also, there is a selection at the bottom of the layers, paths and channels Panel icon that looks like a dotted circle.

  • What is the equivalent of | operator using the Q-quote mechanism?

    Version: 11.2.0.3

    I started a thread on similar requirement last week. I didn't want to resurrect. So, I start a new thread.

    We have a stored procedure called generate_table_stats that meet the stats for tables with a few additional options.

    Usually, this procedure is performed as below

    generate_table_stats exec ('EMP_DTL', 'BASIC');

    We want to generate the exec above instructions dynamically for all tables.

    In the traditional method of quotations, we use the concatenation (|) operator to separate the column names whose values are retrieved dynamically from the table queried.

    Similarly, how can I get a column of values printed when you use the Q-quote mechanism?

    In my column in table_name attempt below must be retrieved from user_tables. But table_name and pipes that are treated as literal string (which is not surprising).

    What is the equivalent of | (concatenation operator) when you use the Q-quote mechanism?

    -Expected results

    generate_table_stats exec ('EMP_DTL', 'BASIC');

    generate_table_stats exec ('CUSTOMER_DTL', 'BASIC');

    Hello

    The concatenation operator. works the same with any string expression.

    x | There

    Returns a string that is the same as sting followed immediately the string x y, x is

    • a literal string with Q before the first single quote
    • a literal string without Q
    • a VARCHAR2 column
    • a function that returns a string, or
    • any string expression.

    The string can be everything above, too.

    If you concatenate strings of 3 or more, like this

    str1. str2. ... || Suro

    then each of the STRS can be any kind of expression, independent of others.

    If you want to concatenate strings of 3, the 1st and the 3rd being Q-literals and the 2nd being a column, you can do it like this:

    Select q' generate_table_stats #exec (#' | table_name)

    || q ' #, ' BASIC'); #'

    From user_tables;

    Each of literals has its own Q and her own pair of start and end markers (all the ' # s in the example above).

    Since the first string literal has no any single-quotation marks incorporated, it is unnecessary to use Q-rating, and it could be misleading; a person who bed the code might think the actaully string contains ' #'s.  I prefer wriite the query in the form

    Select ' generate_table_stats exec (' | table_name)

    || q ' #, ' BASIC'); #'

    From user_tables;

    A slight correction to the post of odie. I think you mean min max to replicate the primary function of access, but see below for sure. So:

    min(upper(trim(tre.dname))) keep (dense_rank first order by tre.gcusno) as dname_std

    user10860953 wrote: how it ignores null values?

    The min and max functions automatically ignores nulls, so if there is a null value in tre.dname, it will not be returned, unless all values are null. For example:

  • What is the equivalent of Adobe Air to CoreData iOS?

    I used CoreData on iOS and love it.  Can someone tell me what is the mobile equivalent of CoreData's Adobe Air?

    I use EncryptedLocalStore to store the user's preferences, but it uses iOS keychain and causes data to persist on the device iOS via an app removal & install.  This is no good, since I'm store preferences that is a little more appropriate for the use of the keyring.  AND I want the app data deleted off the unit once the application is deleted/uninstalled.

    Any ideas?

    My opinion:

    Shared local objects if you want to have your prefs in the form of key/value pairs. or by using E4X with readObject and writeObject file API if you want to have your prefs in XML format.

    The shared secret is a sort of password. It is defined by the VPN server, then this would be the place to start looking. Personally, I have no experience in running Windows Server VPN service, so I can't be more specific, but I hope that puts you in the right direction.

  • What is the genuine product key of Windows, one on the back of the COA, or returned by the MGADiag tool?

    Which is the real key to my new windows. One returned by MGA Diag tool/Jellybean key finder (both give even) or one at the back of my COST?

    There are two types of OEM suppliers. Royalty OEM vendors can distribute Windows products by using the preinstallation (SLP) product keys so that end users can bypass product activations. All other OEM vendors distribute Windows products by using the standard product keys that require the user to activate Windows products.

    If your recovery partition is damaged or missing, or you lose your recovery disk, you can use either the COA key at the rear with a disc of Windows 7 genuine.

  • What is the equivalent of JavaFX from the constructors that accepts arguments?

    I'm sure that there are no constructors in JavaFX because I read somewhere that but how can I get a similar result?

    For example, the goal of the program that I do is simulate a really basic car race and I want to be able to use the code to be red or blue or something else. The equivalent of Java I think East:
    Car car = new Car(Color.RED);
    and the manufacturer of the car class to be:
    public Car(Color color)
{
    this.color = color;
}
    Any help would be greatly appreciated!
    Thanks in advance!

    JavaFX has no constructors, but has init and postinit constructions.
    In your case, you can do without these constructions:

    public class Car {
 var color:Color

} 

var car:Car  = Car {color:Color.RED};
}

  • What is the equivalent of HashTable of Java in PL/SQL

    Hello

    I write a java method that calls a pl/sql procedure. The procedure must accept a single input parameter and I actually pass the parameter of java as a hash table

        protected void doDML(int operation, TransactionEvent e) {
        // super.doDML(operation, e);
        Hashtable record = new Hashtable();  
        String columnName = null;
        if (operation == DML_INSERT) {       
         for (int i =0; i<getAttributeCount(); i++) {
               columnName = this.getEntityDef().getAttributeDef(i).getColumnName();
               System.out.println(columnName+ "=>"+this.getAttribute(i));             
               record.put(columnName, this.getAttribute(i));               
           }
            System.out.println(record.size());
         insertRow(record);
         
        }
        
    }


    public void insertRow(Hashtable table) {
        CallableStatement st = null;
        try {


            // 1. Define the PL/SQL block for the statement to invoke
            String stmt = "begin test_tab_pkg .insert_row(?,?); end;";
            // 2. Create the CallableStatement for the PL/SQL block
            st = getDBTransaction().createCallableStatement(stmt, 0);
            // 4. Set the bind values of the IN parameters
            st.setObject(1,table);


            // 3. Register the positions and types of the OUT parameters
            st.registerOutParameter(2, Types.VARCHAR); //P_REQ_AMT_BASE


            // 5. Execute the statement
            st.executeUpdate();
            //   setReqAmountBase(st.getString(8));
            setErrorMsg(st.getString(2));
            System.out.println(getErrorMsg());
        } catch (SQLException e) {
            throw new JboException(e);
        } finally {
            if (st != null) {
                try {
                    //Close the JDBC CallableStatement
                    st.close();
                } catch (SQLException e) {
                    e.printStackTrace();
                }
            }
        }
    }

    as see you in the code, the method "::InsertRow()" runs a procedure from pl/sql "test_tab_pkg.insert_row(?,?)".

    the first parameter is IN, and the second was RELEASED.

    The problem is that I don't know what type of data I use PL/SQL for parameter 1.I tried an array of records, but it fails. This is my code

    CREATE OR REPLACE package HR.test_tab_pkg 
is
type ADF_ENTITY is table of VARCHAR2(30) index by binary_integer;


procedure insert_row  (prec in ADF_ENTITY , perror out varchar2 ) ;


end  ;
/


    CREATE OR REPLACE package body HR.test_tab_pkg 
is
procedure insert_row  (prec  ADF_ENTITY , perror out varchar2 )
is


begin



insert into test_tab (tab_id  , description ,trx_date  ) 
values (prec(0)  , prec(1) ,SYSDATE ) ;
    
perror:='0';
    
exception 
when others
then perror:=sqlcode ;    
end insert_row;


end  ;

  • In Gimp, there is a command called "color to alpha". What is the equivalent of this command in Photoshop? [please?]

    Untitled.jpegUntitled2.jpeg

    Hi people. Another saltquestion related ection/transparency. Im making this transition from Gimp PS and Im trying to make the process faster by asking specific questions, because its still taking me by watching videos. At this point Im just trying to learn my way around the interface of the program rather than learning the science itself.


    Back to the question: in Gimp "color to alpha" removes a particular color of the image while keeping the other colors intact. Another way to do is to put the tool eraser to remove a particular color when you apply it. How do the exact equivalent or closed cela in Photoshop? Basically, my questions are:


    What command or option use to remove a particular color both in image? [Ex. There is the American flag and I want to turn red in alpha gradients]

    How to set the BRUSH tool to make it an ERASER tool, affecting only a particular color or how to configure the Eraser tool so that it affects only a specific color in the image?


    All your time and info is much appreciated.



    Short answer: No. even after all this time, Photoshop still doesn't offer such a handy tool. There is a Select statement--> the color range option, but it gives quite severe results and does not mix, alpha, etc. into account.

    Alternatively, the BlendIf option can also work in some cases.

    To remove the black (or white if you reverse the image first), the Unmultiply plugin can be used: http://www.ayatoweb.com/download/down04.html

    Although I'm not sure if it still works in the latest version. The developer has created a FilterForge version, which works very well (but requires a license FF).

    An older plugin can be downloaded here:

    http://www.Cybia.co.UK/TheWorks.html

    Only works on 32-bit hosts Photoshop compatible plugin, however. So no luck with a 64-bit Photoshop.

    It's really a shame: Photoline has a bright "color to transparency" no destructive layer (Stackable!) setting that does exactly what Gimp "color to alpha" does, but with a lot more control:

    Here again, no tool offers everything, including Photoshop.  Just run Gimp for these cases.
