Research question table

Hello

I use the following to find the index of a nested table in the 'files' table, which contains an object whose id matches a certain value.  Search objects are in position 0 of each nested table.

function Discovery (id): int

{

for (var i: int = 0; i < folders.length; i ++)

{

If (files [i] [0] user.user == id) return i;

}

}

Find ("my_value");

.. .save me error: function does not return a value

But if I get rid of the: int...

function find (id)

.. .it works.

It's certainly a whole number of return, that I am able to use it later mathemtaically.

Why does this happen?

Thank you

Since the return of the i value is conditional it is possible that the function will fail to return a value.  You should probably reorganize things so that the return happens outside of the loop, where, in the case of any valuable consideration, you return a-1 or another value that could not be tied to an array index.

  • Problems with the service of version 9.0.2? Sudden research questions of text in the output WinHelp files

    I've been building and using the same aid project in multiple versions of Robohelp since 2002 about.  Upgrade to Robohelp 9 earlier this year (Office 2010/Win 7), properly migrated project in RH9 and Word 2010 RH7 and W2003.  Despite being really bug RH9 and doesn't play well with Word, were able to continue to build multiple versions of the project without successfully exit WinHelp 2000 compilation problem, no error messages all basically good.  Until the 9.0.2 update.  Of course, the update fixed the issues of speech, now HR and Word 2010 not play very well. But now I get the dreaded "cannot search, display tab: error 177' Message in compiled projects.»  This same message now appears on WIn XP machines that have the project distributed.  Also find full-text search is available on the Win 7 despite the warning, but on a XP machine machine only partial text is available for searching (so this is not the question of Win7 re display of files HLP - win 7 has all the patches of register machine and MS. HLP Patch installed to run and has not been a problem to date).  Coincidence?  This started to happen since the 9.0.2 update installed?  (The cause of the error message doesn't seem to be the traditional corrupt file GID on PC like on XP machines before the new installed help file, it will be deleted).  Have I somehow changes the settings in the HPJ file or another project file generation?  Is this a problem of indexing that I can fix?  If so someone at - it ideas?  Come to think of him with ideas at all about what is happening here and how can I solve this problem?  (I'm considering back in the initial installation of RH 9 (implemented with Bugs) and see what happens but fear I might have inadvertently installed something version 9.0.2 )

    Another interesting question is that the immediately previous version of this project (built with the Buggy of RH9 version) re - unfolds on the other computers and XP very well.  So why I suspect 9.0.2?  Anyone with some help pls?  Where I could look in settings (if any) to correct the problem?  I tried to re - create a completely new project with the same word documents, but using the origingal. HPJ file and the same problem presented?

    Peter,

    With a lot of relunctance, (probably because of being on holiday and in the middle of the Christmas break), I've rolled up their sleeves and rebuilt the project from scratch. (What else do you ndo when on vacation?-can think of several things). The project is bitmaps quite large, consisting of 38 separate Word Documents, 908 topics, 731 jumps, 907 keywords and 37.  This project was built in 2000 and enjoyed time has reached this size. Each year, some 15 to 20 of the draft versions are built as subjects and content changes.  The propject resulting is distributed on a netwrok involving 3 operating sites and more than 250 terminals.

    The first step in correcting this problem was to place all word documents in word 2010 format (38) project.  Before that documents previously saved in Word 2003 format and open in Word 2010 (compatibility) mode.  On the assumprtion there was a problem of compatibility between 2003 and 2010 word format causing the compiled research questions.  I saved all the latest known version of 'Good' of the project documents in this mode.

    Once all documents saved to Word 2010 format, each document has been individually then imported into the new project, the project saved and built after each document imported.  This was done for was the origin of the problem to ensure that a particular document.  None appeared.

    Once that all the 38 documents any OCD has created the last well-known CNT file.  Imported into this new project in the form of measurements of the CNT old file rather than use then file itself.  Project saved and rebuilt again.  Still good.  I used the text instead of the CNT file again just to try to eliniate hidden, coding of corruption in the file of the CNT.

    Then the sequences to browse relevant have been updated in order to meet the requirements, project archived for proken links (found nothing) or any other error.  Once again.  Nothing found.  Re-built and still saved.  No problem identified with the project.

    At this point the last well-known version has been restored in a new project just in Word 2010, format, changes in the (next) version of fault had not yet been restored to the project.  5 files in this version had a lot of changes that I have taste not individually make each change.  In order to reduce to a minimum rework them, I took the opportunity to copy the text of the documents and paste the text into the new word format documents (rather than import something that may have corrupt and coding). In each case I deliberately does not include the first or the last lines of the documents in the copied text, again try to eliminate the import of any coirruption that may have existed?  Yet once, save and rebuild the project after each import text.

    Final score, a return without erors project.  Tested on 2 different local machines (both running Win 7 with Winhelp patch applied) no error returned.  Deploy the updated on the work network this morning.  (XP systems), yet once no erors returned and full don't search feature now available.

    So, what was the problem?  Not sure that I'll never know, (I have a second project on another topic which is still in Word 2003 format, built under this version of RH9 and she does not have the same problems I had in this project).  Whatever, it was an absolute pain, many lost hours, but a positive result (finally).

    Thanks to you and the people who have offered nhave his help.

  • Is it possible to change data in a cell 'mirror' + RESEARCH questions?

    Hi all!

    The idea is the following:

    I have an accounting base numbers document implemented that automates the process of encoding of individual invoices, clients, with their price + coupons service announcements and summarizes the accounting.

    Information boards is implemented for individual receipts, or a nicer individual record to customer research with the research

    That's where I met 3 barriers:

    (1) I was wondering if it was possible for a field in one datasheet to other mirrored? :

    -L' idea is NOT to have a simple '= A$ $1 ' or ' = LOOKUP (REF., range, content) not allowing editing. "

    -It is a cell on A page SHARE the SAME content in another cell in the spreadsheet b: change in the sheet A or B would automatically change the field of mirror in the other sheet. It would be a very neatly to create a form for the encoding of the data! Somehow, I have my doubts about what is a feature of the numbers, but I was wondering if anyone knew a workaround? In other words: a field at several places.

    (2) instead of a SEARCH function that the problem of data modified in the original table (example: a Bills (past) sheet being affected by changes made to a price list): is there an equivalent of 'paste values' to that?

    (3) I have a 'General' Journal (and a table) to display financial data from my "bills", but the info is basically just a table with the "' values sought my table"bills ". It works very well with the "auto-fill" when I manually adjust the size of the table, as the invoice automatically filled when increasing the size of the table. I was wondering if there was a) an easier way to do what I know and b) a way for the "accounting" array to dynamically adjust its size according to the number of invoices (same result as one)).

    ANY help is greatly appreciated!

    Christian

    Hi Christian,

    Brief answers to three questions:

    1. # Research reports are always a sense - entered into a data cell can be collected by a formula in a cell of the second, but the data entered into the second cell will not create a change in the first cell. A cell can contain a "fixed" value, which can be changed manually in this cell, or it may contain a formula that combines the data of one or more other cells and eventually made some calculations before displaying the result.
      A cell that contains a formula of edition replaces the formula with the data entered.
    2. The formulas are always "live". If the result of the formula is based on data specific to a cell, then a change in the data (e.g. a price) in this cell will change the result calculated by the formula and displayed in the cell. The result can be 'fixed' (made to the remain the same, not "fixed") using values of dough (renamed paste formula results), but this can be done by using a formula.
    3. Size (number of rows) of the table 'accounting' (or ' table on the "journal") can not be adjusted automatically depending on the size (number of rows) of the table "bills". In the "accounts" table formulas are automatically added as every cell in the column of the first row header not the above one row being added contains the same formula. Replacing any copy of this formula with the calculated results by that copy breaks the chain and the formula prevents fill automatically new lines added at the end of the table.

    Some general considerations:

    All data should be entered only once.

    Data entry must be separated from the calculation to avoid the accidental destruction of the formulas.

    Data 'Immutable' (eg. current prices, data on clients) may be imposed and looked up from lookup tables.

    This has the potential of growth to a large set of data. Numbers are known to slow down considerably with the large data sets (and 'big' happens quite quickly).

    With regard to price changes:

    Use the INDEX and MATCH the prices of research allowed the transaction date to control the INDEX column will return a price. Each price change (or set of price changes) is entered in a new column, marked with the data hence these prices are in effect. Price unchanged compared to the previous date of change should also be included in the new column.

    Kind regards

    I have a sensor that contains 4 channels of power. I need to keep all 4 active channels, but I want to choose one of them to the chart at any given time. The data from the driver OR hardware comes in form of table of 2 elements 1 x 4 clusters.

    Normally, I had just index for the item in table 1 x 4 and feed on this cluster to the right graphic tool, but I'm missing something. I had a display of the sample driver NI of VI element, but anytime I insert blocks between the stream and the graphic I get errors "bad connection".

    I've been googling and book-research for several days now, nothing helps, I'd appreciate any help in this matter.

  • Windows Live Mail 2011 research question

    I have recently installed Windows Live Mail 2011 and since I installed it, I noticed that when I enter a word or name, or e-mail address in the search for a message function, it very often does not find the email (s) concerned. I come to find the message manually. On the old version of Live mail, everything worked fine.

    Any ideas on what could be the cause and how to fix this problem?

    BTW. My OS is W7 32-bit

    Respectfully, Ronnie, who is not very useful. Windows Live Mail depends on Windows Search for his research works, so if it does not work, there is a problem with WS and not with WLMail. The question is quite on the topic in this forum, and Dave is not likely to get a quick settlement more in windowslivehelp.com.

    @Dave:

    First things to check is that your storage folder is being indexed and if mail messages files are being indexed with the properties and content. In WLMail, locate your store folder by opening the worksheet Options (Ctrl-Shift-O), the Advanced tab, click Maintenance , and then store the fileopening. Note the path.

    Open Indexing Options in the control panel (just type indexing options in the start search box). Click on the Edit button, navigate to your storage folder and ensure that the box is checked.

     
    Click the Advanced button and open the tab file types ensure that the check box next to the eml and nws rss extensions are checked and that the description of filter shows Windows Live MIME filter. Click on each extension in turn and make sure that the properties of the Index and the content of the file is selected at the foot of the dialogue for each of them.
     
    If these settings are what they should be and you make changes, try solving the problems of search and indexing in the Panel. Start typing the search and indexing in the search box of the start up until you can see and select find and fix problems with Windows Search at the top of the results panel. Do not select the mail option; Windows Search considers Windows Live Mail messages as files, not e-mail.
     
    If after all that your searches don't work always, after the return.

    Hello Rahul,

    When you refer to a table or view in a procedure, function or a package, you must have a direct grant to the user and not by a role.

    In your case:

    GRANT SELECT ON sys.dba_constraints TO rahul;
    

    should work.

  • Various noob questions, tables

    Hey all,.

    This isn't really an issue, but as I am just learning AS3 as best as I can, I thought I'd use understand you smart people to help me better things.

    I'm in book of Gary Rosenzweig (good info, but very difficult for me to grasp the logic and keep track of all the variables) and has recently created the "Deduction". It works, but I don't feel that everything has been explained as well as it could have been.

    1. could someone maybe break what happens at the hearing "because" for tables are created?



    private var currentRow:Array;

    //

    currentRow = new Array();

    for (var i: uint = 0; i < numPegs; i ++) {}

    var newPeg:Peg_mc = new Peg_mc();

    newPeg.x = i * pegSpacing + horizOffset;

    newPeg.y = turnNum * rowSpacing + vertOffset;

    newPeg.gotoAndStop (1);

    newPeg.buttonMode = true;

    newPeg.pegNum = i;

    newPeg.addEventListener (MouseEvent.CLICK, clickPeg);

    newPeg.setChildIndex (newPeg, 5); ASK QUESTIONS ABOUT AS3 FORUM

    addChild (newPeg);

    allDisplayObjects.push (newPeg);

    records pegs as an array of objects

    currentRow.push ({peg: newPeg, color: 0});

    }

    Is something like this: you want a new table, and 'for' is used to help determine the number of objects or "slots" need to be created for this table? ( I use the variable 'creation' because it's just practice?) Below, I start at 0, is assumed to be 1 less than the number and needs 1 added to the amount (a constant) numPegs i (++), until it is equal to i < numPegs...

    something like that?

    2 I vaguely remember the book mentioning that tables can create content ' on the go ' or 'dynamic' - for example, currentRow.push ({peg: newPeg, color: 0}); creates the 'peg' and 'color' attributes without needing a definition for them earlier in the script.

    Any help would be appreciated. Just realize that I'll probably ask a LOT more questions in the coming weeks. (I am creating a game of my own).

    The 'i' used in the loop is commonly used as a variable name for a loop counter.  In another life/language "n" used to be the most popular choice.  It may be named any unreserved name you like.  With the help of 'i' is short and sweet.

    Tables begin at an index of 0, which is why the 'I' start at 0.  numPegs dictates ankles how you want to create.  As I starts at 0, as soon as I is 1 less than numPegs, the work is done.

    Tables cannot create content dynamically.  They can store references to the dynamically created content, but cannot create this content.  The content had to be created elsewhere.

  • Trigger Oracle (INSERT ONLY) question (Table of historical data)

    What I have to do is follow the changes that are taking place on a table. The requirement is that it must be a trigger. The question I have is that a MERGE statement is moving data to another table that I monitor, which creates tons of changes (which are really just duplicates).

    The underside of work... with the exception of INSERTING it. When a change or remove met him, archives... but not INSERT it. I noticed that when I put where when to '=' instead of '<>', INSERTS will be saved (but obviously when new old =, which I don't want). The problem seems to be the "WHEN".

    Any suggestions...?

  • Delete the Simple question table

    OK, so I promise you, I'm not a fool, but I could be lying at the monment.  I have a table, an orgenized good demisional, I need the unique elements.  I wrote an admitted that it is a little messy method to do such a thing, but it works logically for me for the most part.  The table currently has 69 items, and at the present time, there are only two unique values.  I could just listed them but that would mean I have to roll updates whenever a new brand comes out.  So now, when I run my program it will remove about half of the table and decides that he doesn't have to obey logic more and keep the rest.   I compied the segment of code that is the problem and registered as a VI for your pursoual and I wired in a copy the avictive table so that you can see what I mean. The code works wonders for 35 early iterations of the loop, and then something goes wrong terriably.

    Hello world

    I know that I can use a table to reshape to convert a 2D 1 d.

    But I'm curious of know how is it when I wire a 2D in an array of index table, and there is no constant for the index entries, the result comes out as a 1 d array?

    How it works in this case? could someone please explain that to me?
