  • Performing multiple fetches in Core Data within the same view

    - by yesimarobot
    I have my CD store setup and everything is working. Once my initial fetch is performed, I need to perform several fetches based on calculations using the data from my first fetch. The examples provided from Apple are great, and helped me get everything going but I'm struggling with executing successive fetches. Any suggestions, or tutorial links are appreciated. Table View loads data from CD store. When a user taps a row it pushes a detail view The detail view loads details from CD. [THE ABOVE STEPS ARE ALL WORKING] I perform several calculations on the data fetched in the detail view. I need to then perform several other fetches based on the results of my calculations.

  • How to get the action from the HttpServlet request to dispatch to multiple pages

    - by JFB
    I am using the Page Controller pattern. How could I use the same controller for two different pages by detecting the request action and then dispatching according to the result? Here is my code: account.jsp <form name="input" action="<%=request.getContextPath() %>/edit" method="get"> <input type="submit" value="Modifier" /> </form> Account Servlet public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { System.out.println("received HTTP GET"); String action = request.getParameter("action"); if (action == null) { // the account page dispatch(request, response, "/account"); } else if (action == "/edit") { // the popup edit page dispatch(request, response, "/edit"); } protected void dispatch(HttpServletRequest request, HttpServletResponse response, String page) throws javax.servlet.ServletException, java.io.IOException { RequestDispatcher dispatcher = getServletContext() .getRequestDispatcher(page); dispatcher.forward(request, response); } }

  • Problem with multiple checkbox

    - by Pushpendra
    I am using a checkbox that has the name selectedids[], and I am trying to select all checkbox with the JavaScript but the code is not working. However, when I change the name of checkbox to selectedids it works but I can't do so because I need all the ids that are selected on the POSTED page. The checkbox is as follow. foreach($rows as $row) { <input type="checkbox" name="selectedids[]" value="<?php echo $row['id']; ?>" class="checkbox" /> ........ ........ } And the Java-script function is as follow function SetAllCheckBoxes(CheckValue) { var CheckValue=true; if(!document.forms['main']) return; var objCheckBoxes = document.forms['main'].elements['selectedids[]']; if(!objCheckBoxes) return; var countCheckBoxes = objCheckBoxes.length; if(!countCheckBoxes) objCheckBoxes.checked = CheckValue; else // set the check value for all check boxes for(var i = 0; i < countCheckBoxes; i++) objCheckBoxes[i].checked = CheckValue; } Please help me. Thanks in advance..

    i'm trying to build a debug and release version of a library with a Makefile and copy those libraries to the relevant build directories, e.g. .PHONY: all clean distclean all: $(program_NAME_DEBUG) $(CP) $(program_NAME_DEBUG) $(BUILD_DIR)/debug/$(program_NAME_DEBUG) $(RM) $(program_NAME_DEBUG) $(RM) $(program_OBJS) $(program_NAME_RELEASE) $(CP) $(program_NAME_RELEASE) $(BUILD_DIR)/release/$(program_NAME_RELEASE) $(RM) $(program_NAME_RELEASE) $(RM) $(program_OBJS) $(program_NAME_DEBUG): $(program_OBJS) $(LINK_DEBUG.c) -shared -Wl,-soname,$(program_NAME_DEBUG) $(program_OBJS) -o $(program_NAME_DEBUG) $(program_NAME_RELEASE): $(program_OBJS) $(LINK_RELEASE.c) -shared -Wl,-soname,$(program_NAME_RELEASE) $(program_OBJS) -o $(program_NAME_RELEASE) The 1st target in all (program_NAME_DEBUG) compiles OK but the 2nd, (program_NAME_RELEASE) produces the following error: libGlamdring_rel.so make: libGlamdring_rel.so: Command not found make: *** [all] Error 127 libGlamdring_rel.so is the value of program_NAME_RELEASE It doesn't seem to be recognising the 2nd target as it does the 1st?

Is there anyway i can do this currently? I know this is not good, yada, yada, but it has to be done for now unfortunately. Thanks, Derek

  • PHP Foreach statement issue. Multiple rows are returned

    - by Daniel Patilea
    I'm a PHP beginner and lately i've been having a problem with my source code. Here it is: <html> <head> <title> Bot </title> <link type="text/css" rel="stylesheet" href="main.css" /> </head> <body> <form action="bot.php "method="post"> <lable>You:<input type="text" name="intrebare"></lable> <input type="submit" name="introdu" value="Send"> </form> </body> </html> <?php //error_reporting(E_ALL & ~E_NOTICE); mysql_connect("localhost", "root", "") or die(mysql_error()); mysql_select_db("robo") or die(mysql_error()); $intrebare=$_POST['intrebare']; $query = "SELECT * FROM dialog where intrebare like '%$intrebare%'"; $result = mysql_query($query) or die(mysql_error()); $row = mysql_fetch_array($result) or die(mysql_error()); ?> <div id="history"> <?php foreach($row as $rows){ echo "<b>The robot says: </b><br />"; echo $row['raspuns']; } ?> </div> It returns me the result x6 times. This problem appeared when I've made that foreach because I wanted the results to stuck on the page one by one after every sql querry. Can you please tell me what seems to be the problem? Thanks!

  • [Apache] Creating rewrite rules for multiple urls in the same folder

    - by DavidYell
    I have been asked by our client to convert a site we created into SEO friendly url format. I've managed to crack a small way into this, but have hit a problem with having the same urls in the same folder. I am trying to rewrite the following urls, /review/index.php?cid=intercasino /review/submit.php?cid=intercasino /review/index.php?cid=intercasino&page=2#reviews I would like to get them to, /review/intercasino /submit-review/intercasino /review/intercasino/2#reviews I've almost got it working using the following rule, RewriteRule (submit-review)/(.*)$ review/submit.php?cid=$2 [L] RewriteRule (^review)/(.*) review/index.php?cid=$2 The problem, you may already see, is that /submit-review rewrites to /review, which in turn gets rewritten to index.php, thus my review submission page is lost in place of my index page. I figured that putting [L] would prevent the second rule being called, but it seems that it rewrites both urls in two seperate passes. I've also tried [QSE], and [S=1] I would rather not have to move my files into different folders to get the rewriting to work, as that just seems too much like bad practise. If anyone could give me some pointers on how to differentiate between these similar urls that would be great! Thanks (Ref: http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html)

  • GDI: Dynamical Multiple Graphics in a page?

    - by SirLenz0rlot
    Hi all, I'm quite new to drawing shapes, graphics, bitmaps etc. I googled for a few days,but still havent got a real clue what to do, so please help me: I want to draw a floorplan with certain objects(represented as circles) moving on it. When I click on a object, it needs to show something. So far, I ve been able to draw some circles on a graphic and been able to move the dots by clearing the graphic every time. Ofcourse, this isnt a real solution, since I cant keep track of the different objects on the floorplan (which i need for my clickevent and movings). I hope I explained my problem ok here. This is the (stripped version of the) sourcecode that gets called every second: (dev (of type Device) is the object i want to draw) Graphics gfx = FloorplanTabPage.CreateGraphics(); gfx.Clear(Color.White); foreach (Device dev in _deviceList) { Pen myPen = new Pen(Color.Black) { Width = 10 }; dev.InRoom != null) { myPen.Color = Color.DarkOrchid; int x = dev.InRoom.XPos + (dev.InRoom.Width / 2) - 5; int y = (dev.InRoom.YPos + (dev.InRoom.Height / 2) - 5; if (dev.ToRoom != null) { x = (x + (dev.ToRoom.XPos + (dev.ToRoom.Width / 2)) / 2; y = (y + (dev.ToRoom.YPos + (dev.ToRoom.Height / 2)) / 2; } gfx.DrawEllipse(myPen, x, y, 10, 10); gfx.DrawString(dev.Name, new Font("Arial", 10), Brushes.Purple, x, y - 15); } }

  • Multiple left joins, how to output in php

    - by Dan
    I have 3 tables I need to join. The contracts table is the main table, the 'jobs' and 'companies' table are extra info that can be associated to the contracts table. so, since I want all entries from my 'contracts' table, and the 'jobs' and 'companies' data only if it exists, I wrote the query like this.... $sql = "SELECT * FROM contracts LEFT JOIN jobs ON contracts.job_id = jobs.id LEFT JOIN companies ON contracts.company_id = companies.id ORDER BY contracts.end_date"; Now how would I output this in PHP? I tried this but kept getting an undefined error "Notice: Undefined index: contracts.id"... $sql_result = mysql_query($sql,$connection) or die ("Fail."); if(mysql_num_rows($sql_result) > 0){ while($row = mysql_fetch_array($sql_result)) { $contract_id = stripslashes($row['contracts.id']); $job_number = stripslashes($row['jobs.job_number']); $company_name = stripslashes($row['companies.name']); ?> <tr id="<?=$contract_id?>"> <td><?=$job_number?></td> <td><?=$company_name?></td> </tr> <? } }else{ echo "No records found"; } Any help is appreciated.

  • mysql - check if data exists across multiple tables

    - by Dd Daym
    I am currently running this query inside MySQL to check if the specified values exists within the table associated with them. SELECT COUNT(artist.artist_id), COUNT(album.album_id), COUNT(tracks.track_id) FROM artist, album, tracks WHERE artist.artist_id = 320295 OR album.album_id = 1234 OR tracks.track_id = 809 The result I get from running this query is all 1, meaning that all the statements after the WHERE clause is true. To further check the query's reliability, I changed the tracks.track_ = 809 to 802, which I know does not match. However the results displayed are still all 1, meaning that they were all successfully matched even when I purposefully inserted a value which would not have matched. How do I get it to show 1 for a match and 0 for no matches within the same query? EDIT: I have inserted an image of the query running

  • SELECT Statement without duplicate rows on the multiple join tables

    - by theBo
    I have 4 tables built with JOINS and I would like to SELECT DISTINCT rows on the setsTbl.s_id so they always show regardless if there's relational data against them or not!. This is what I have at present which displays the data but doesn't display all of but not the entire distinct row! SELECT setsTbl.s_id, setsTbl.setName, userProfilesTbl.no + ' ' + userProfilesTbl.surname AS Name, trainingTbl.t_date, userAssessmentTbl.o_id FROM userProfilesTbl LEFT OUTER JOIN userAssessmentTbl ON userProfilesTbl.UserId = userAssessmentTbl.UserId FULL OUTER JOIN trainingTbl ON userAssessmentTbl.tt_id = trainingTbl.tt_id RIGHT OUTER JOIN setsTbl ON trainingTbl.s_id = setsTbl.s_id WHERE (userProfilesTbl.st_id=@st_id AND userProfilesTbl.sh_id=@sh_id) AND (DATEPART(yyyy,t_date) = @y_date ) OR (userAssessmentTbl.o_id IS NULL) ORDER BY setName ASC, t_date ASC With this statement I get some of the rows (the ones with data against them) but as stated the s_id field does not return distinct. This following inner select statement works in part when used in SQL Query analyzer and returns pretty much the data i require s_id setName Name o_id ----- ----- ----- ------ 1 100 Barnes 2 2 100 Beardsley 3 3 101 Aldridge 1 4 102 Molby 2 5 102 Whelan 3 but not when used outside of that environment. select * from ( SELECT userProfilesTbl.serviceNo + ' ' + userProfilesTbl.surname AS Name, userProfilesTbl.st_id, userProfilesTbl.sh_id, userAssessmentTbl.o_id, setsTbl.s_id, setsTbl.setName, row_number() over ( partition by setsTbl.s_id order by setsTbl.s_id ) r FROM userProfilesTbl LEFT OUTER JOIN userAssessmentTbl ON userProfilesTbl.UserId = userAssessmentTbl.UserId FULL OUTER JOIN trainingTbl ON userAssessmentTbl.tt_id = trainingTbl.tt_id RIGHT OUTER JOIN setsTbl ON trainingTbl.s_id = setsTbl.s_id ) x where x.r = 1 Not receiving any errors just not displaying the data?

  • jquery : ul, li parent multiple child sub-child toggling

    - by user360826
    hello, my main question is as follows: how to show only the first subchild of a ul or li upon clicking the enclosing parent. eg: <ul> Grandparent <li> Child1 <li> Grandchild11</li></li> <li> Child2 <li>GrandChild21</li><li>grandchild22</li></li> </ul> so, for example I would like something to the effect of <script> $('ul').click(function(){ $('ul').children('first li').toggle() }); $('li').click(function(){ $('li').children('first li').toggle() }); </script> meaning: when i click ul, i only see the first child node (child1 and child2 will be shown, but not the grandchildren). when i click child1 or child2 i see the respective grandchild. grandchild is not shown upon clicking grandparent, only upon clicking child1 or child2. i know i am reinventing the wheel of some pre-coded solution, but any help would be largely appreciated!

  • How to deal with multiple Facebook requests simultaneously

    - by Peter Warbo
    I'm using the Facebook SDK for my app. I have created a singleton class FacebookHelper to deal with all Facebook related logic. Whenever I make a Facebook request (i.e download friends) I set an enum i.e FacebookRequestDownloadFriends so that FacebookHelper knows how to handle errors and success for that request (since handling can be different between the different requests) This solution has worked out fine until now, because now I'm doing 2 Facebook Requests at the same time so when I set the enum for the first request i.e FacebookRequestDownloadFriends and then it will be overwritten just shortly with another request FacebookRequestDownloadEvents, so there will be confusion obviously. How can I deal with this issue without having to refactor too much code?
