A function or a way to identify a word before any tank

Hi all
I'm looking for a way to identify the FIRST Word BEFORE any specificity. For example:
I have a string: "" this * day *, October * is * very * Sunny *, "".
I want to know if there is a function or a logic to simply identify the FIRST Word before ',' (here ',' is the specific character).
The solution would be: "the day is sunny.
Kindly let me know.
Thank you

Hello

This sounds like a job for regular expressions.

REPLACE ( REGEXP_REPLACE ( txt
                  , '[^, ]+'     -- anything that's not a comma or space (1 or more)
                    || '( |$)'     -- right before a space (or end)
                )
     , ','
     )

I guess a "word" is a group of one or more characters that does not include a comma or a space.
Are other punctuation characters (as "."and"") ") delimit words, so this will need to be adjusted."

The REGEXP_REPLACE removes all words that don't stop not a comma. The comma at the end of every Word retained part of the results.
Because you don't want commas in the output, I used REPLACE to get rid of them.

    You can write a JavaScript that would do this. You will create a JavaScript script at the level of the Document in a 'special' PDF file you create also (can be a blank page). If no, when you open this 'special' PDF this JavaScript could loop through all of the PDF files in a folder, open each one, check if an open PDF file has a signed signature field and log the name of the PDF file. You will need to know the programming JavaScript, Acrobat JavaScript API (Google for References and tutorials) and knowledge of the PDF files for this structure.

  • What is the best way to work with Word documents in The InDesign CS4?

    I work in Microsoft Word 2007 and all my documents have.doc format.

    What is the best way to work with Word documents in InDesign CS4?

    David Blatner says to avoid copying and pasting text from Word instead of placing (Ctrl + D).

    How to paste RTF or text Document?

    I want to do a book layout in ID CS4 and its main feature is that there is the left page with the text and the right - with graphics.

    So, if I understand correctly place the text on each page I create for example 70 Word documents and place each element on 70 pages left?

    He loks like wasting time. I have supplements another way to make such provision?  What kind?

    It is best to place any text.

    You can have all your text in a single file and debit allows you to add text, images and pages as necessary block (hold down the SHIFT key when you click the loaded text cursor), but it is somewhat atypical for the thread on one side of the spread in the perspective of automatic flow, so you don't have to set up properly.

    It is a case where a block of text that you type will work to your advantage. On your master page, add a text block to the left page, but not to the right (or at least not donned one to the right - for another project you can actually two threads of independent text). Hold the cursor of the load on a frame on the left side of a page document and auto-flux. ID will add new spreads as needed, but only to put the text on the left side.

  • What is the best way to identify corresponding ctrl/indctr an orphan of the label?

    Forgive me for what may be a stupid question but in some sort a label has been separated from its control or its indicator in my original (large) block diagram - I'm curious to know if there is a quick way to find the associated control or indicator? Maybe a combo strikes of somesort?

    Thank you

    -pat

    Don't know if it's the easiest way, but you can try this:

    Select the orphan label on the BD, press CTRL + F (opens the find and Replace dialog box)

    Select search text

    Type the label name

    The search result should show 2 results, the label of the control in the public Service and the label on the BD

    If you go in the control and right click and select find terminal, you will find the terminal associated with the label an orphan.

  • Is there a way to identify a code product?

    Often, I reinstall windows on laptops for friends and I would say that it is a very common problem where the ACO gets blurry point of being unreadable. If the product key is not readable, I know that that the of it forget, but sometimes the actual key is readable, but the product is called fuzzy which can be annoying because then I don't know whether to install windows 7 Home premium Edition or ultimate edition or windows XP Pro or Home. Often, however, the product (x 13-04660 or x 11-45371) code is visible. Is - this here anyway to identify what these products are with this code? Google has had very little information about these codes.

  • Is there a way to identify the reason for the disk activity?

    I am running Windows XP SP3. I often hear my hard drive makes a lot of disk activity as long as 20 minutes or more. No request probably appear in the Task Manager, and I don't think that the application using the more memory is necessarily the same responsible for application of the disk activity. I have not all the scheduled running backups, so this isn't the reason. Is there a software to help me identify what kind of reading/writing happens in the middle of this?

  • Quick way to identify unused advanced actions?

    I have a number of advanced actions that I no longer use. Is there a quick way to find (similar to the conclusion of the unused objects in the library) or to see if they have been used? Or should I simply select each one and see if it allows me to remove it?

    To see if a tip action is used, select it in the advanced Actions dialog box and click the use button. But do for each action, not for objects in the library (which is possible for shared stocks).

  • Best way to identify the members of old / unused

    Hi all

    We had our planning application for almost 4 years now and to keep it nice and thin that we are eager to do a review of our dimensions and remove all members that have not been used in the last 2 years.

    I was wondering if there are ways recommended on the identification of members which have not been used in the last 2 years?

    Currently the only way us can think must either make a MDX query or a Smart View to the list of members who have no 2010 YearTotal amount, but creates the risk of kidnapping
    (1) members who come to be created
    (2) members who have some movement in the year but the total zero

    Any suggestions?

    Published by: PLIM on January 30, 2013 08:37 - clarify

    I would say that you should use sql to understand this.

    Take the export of data and load it into a table.
    Compare distinct members in your table in outline.
    Who is not export, but is in need of major lines to remove.

    For someone who is handmade to SQL, must be like a couple of hours.

  • Writing user defined function the same way as the oracle functions

    Hi guys,.

    In one of the interviews, I saw the guy asked me to write a function defined by the user who will be the column name and the list of all values.

    For example

    Name: employees table
    Column name: Employee_Name

    Employee_name
    Scott
    Ivgun
    Jack
    Shane

    The query must be in this marker

    SELECT col_agg (Employee_name) emp_name of employees;

    The output must be

    Emp_names
    Scott, ivgun, jack, shane

    Please let me know if this is possible

  • Passing the value to the function clears the default value of the textBox before onClick

    I created a 'clearTextBox()' function so that when an edittext obj is clicked in the default text disappears. He works until I try to spend the 'default' text in the service, to which cases it erases the text without the onClick. See: "textBox.line01.onClick = clearTextBox (textBox.line01, defaultText01);"

    myGUI (this);

    function myGUI (thisObj) {}

    var myGUIPalette = myGUI_buildUI (thisObj);

    function myGUI_buildUI (thisObj) {}

    var myPanel = (thisObj instanceof Panel)? thisObj: new window ("palette", "user input panel', undefined, {resizable: true}");

    {//Build GUI

    res = "group {orientation:"column",-}".

    titleGroup: group {orientation: 'row', \}

    //TextBox settings

    var defaultText01 = "enter the text of the line 01 ';

    var defaultText02 = "enter the text of the line 02."

    var defaultText03 = "enter line 03 Text."

    var myPanel.grp.textLineGroup = textBox;

    textBox.line01.text = defaultText01;

    textBox.line01.onClick = clearTextBox (textBox.line01, defaultText01);

    function clearTextBox (activeTextBox, defaultText) {}

    if(activeTextBox.Text == DefaultText) {}

    activeTextBox.text = "";

    Hi sbaden04.

    Your syntax does not work, since the textBox.line01.onClick = clearTextBox (textBox.line01, defaultText01); entitled to textBox.line01.onClick the result of the right side, which is not a function, but undefined. You can try this way:

    textBox.line01.onClick = function() {clearTextBox (textBox.line01, defaultText01) ;};}

    Or like this:

    textBox.line01.properties = {defaultText: defaultText01};

    textBox.line01.text = defaultText01;

    textBox.line01.onClick = plain text;

    function clearText() {if (this.text = this.properties.defaultText) this.text ="" ;};}

  • In Windows 7, is there a way to display a screensaver before connect you?

    I have a screen saver that appears on a monitor in a public place.  I'm trying to understand how the screen saver can play without the first user logon.  Is there as a way to do this?

    Hi Ben,

    If these channels are not there, it is acceptable to right click on an empty space and create them.  Make sure that you request them to .default under the HKEY_USERS location, this is the logon screen area.  The "HKEY_CURRENT_USER area is just the person who is recorded at the same time (it is a copy of the corresponding user's location, but that's beyond the point)."
    Adding these lines to the .default desktop settings should work as you wish.  However just to clarify, this will affect the login screen, so it only works if no user is connects to the desktop computer.
