  • creating managed objects using code in xcode & core-data

    - by themadpeacock
    New to objective-c xcode and core-data so sorry for the remedial question. I have set up a very simple data model: Entity1 and Entity2, both contain a single attribute (String) and a one-to-many relationship with the other. I want to scan Entity1 and depending on the results of the scan create one or more Entity2 objects that link to Entity1. How can I do this? I don’t understand how I create Entity2 type objects in code and how I would define the relationship to the Entity1 object they are related to. I come from a SQL programming background where inserting elements into the Entity2 table with the ID of the related Entiry1 entry is easy. I can’t get my head around the xcode core-data abstraction and would appreciate any help.

  • Creating a Model using Stored Procedures with Zend Framework

    - by jwhat
    I'm using Zend Framework and I'd like to build a model to perform read/write operations on a database... using stored procedures. I know how stored procedures work, but I have yet to use them within Zend Framework. Is there any built in support for stored procedures that I should know about? What is the best practice way to create a model in this senario? Should I extend Zend_Db_Table_Abstract or some other class?

  • error by creating process

    - by Tyzak
    hello i want to get startet with programming with WIN32, therefore i wrote a programm that creates a process but in the line of code where i create the process the programm gets an error an dosn't work (abend). i don't know if the code in programm 1 is wrong or the code in the second programm that should be created by the first. ( I don't know if the code in the first programm after "createprocess" is right because i didn't get further with debugging, because in this line i get the error.(i tested it without the cout,waitforobject and close handle but i didn't work either )). First Programm: #include <iostream> #include <windows.h> #include <string> using namespace std; void main() { bool ret; bool retwait; STARTUPINFO startupinfo; GetStartupInfo (&startupinfo); PROCESS_INFORMATION pro2info; ret = CreateProcess(NULL, L"D:\\betriebssystemePRA1PRO2.exe", NULL, NULL, false, CREATE_NEW_CONSOLE, NULL, NULL, &startupinfo, &pro2info); cout<<"hProcess: "<<pro2info.hProcess<<endl; cout<<"dwProcessId: "<<pro2info.dwProcessId <<endl; retwait= WaitForSingleObject (pro2info.hProcess, 100); retwait= WaitForSingleObject (pro2info.hProcess, 100); CloseHandle (pro2info.hProcess);//prozesshandle schließen retwait= WaitForSingleObject (pro2info.hProcess, 100); ExitProcess(0); } Seconde Programm: #include <iostream> #include <windows.h> #include <string> using namespace std; void main() { int b; b=GetCurrentProcessId(); cout<<b<<endl; cout<<"Druecken Sie Enter zum Beenden"<<endl; cin.get(); //warten bis Benutzer bestätigt Sleep (700); ExitProcess(0); cout<<"test"; } Thanks in advance

  • Help creating a predicate for use with filteredArrayUsingPredicate

    - by johnbdh
    I am trying to learn how to use predicates and so am trying to replace the following working code with filteredArrayUsingPredicate... [filteredLocations removeAllObjects]; for (NSString *location in locations) { NSRange range = [location rangeOfString:query options:NSCaseInsensitiveSearch]; if (range.length > 0) { [filteredLocations addObject:location]; } } Instead I am trying.... [filteredLocations removeAllObjects]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF contains %@", searchText]; [filteredLocations addObjectsFromArray: [locations filteredArrayUsingPredicate:predicate]]; I am not getting the same results with the predicate as I am with for loop rangeOfString. With the range of string for example searchText returns an 8 item array while with the same value returns only 2 with the predicate. Another example, hono will find honolulu in the locations array while it will not find anything using the predicate. As I understand it SELF represents the object object being evaluated ie. the locations array, so I think that is the correct syntax. Any help would be appreciated Thanks, John

    My windows form application has a grid view control with filename as a default column. User should create a column of following types Text, Number, Currency, Combo Box, Check Box, Radio Button ,Date time type (should display DateTimePicker control) and Hyper Link type.

  • Creating a subscription based website in ASP.NET

    - by DotnetDude
    I'd like to update my website to make it subscription based. It's a ASP.NET Web forms project. I am looking for the following functionality: Ability to have users sign up for different plans (Gold, Premium etc) Ability to have users upgrade / downgrade to and from plans Ability to hook this up to a Payment processor Ability to have a credit based system (User buys x credits for $y) as an alternative to plans in (1) Most of this functionality (if not all) is supported by a large number of websites which makes me think I can leverage on an existing framework instead of re-inventing the wheel. Any thoughts?

    Hello, I am trying to create a listview that has check box beside each item. (i am following a code from the book android), but i can't get it to work, every time i run it, it crashes. since i am very new to this android staff, i have no clue what to do to get it to work, any help is appreciated.the code is below. *i have created two layout files in names of list and list_item. the code for the main activity: public class ListDemoActivity extends ListActivity { /** Called when the activity is first created. */ String[] listItems = {"exploring", "android","list", "activities"}; private SimpleCursorAdapter adapter; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.lists); //setListAdapter(new ArrayAdapter(this,android.R.layout.simple_list_item_1, listItems)); //setContentView(R.layout.lists); Cursor c = getContentResolver().query(People.CONTENT_URI, null, null, null, null); startManagingCursor(c); String[] cols = new String[]{People.NAME}; int[] names = new int[]{R.id.row_tv}; adapter = new SimpleCursorAdapter(this,R.layout.list_item,c,cols,names); this.setListAdapter(adapter); } } the lists file content: <?xml version="1.0" encoding="utf-8"?> and the list_item file content: <?xml version="1.0" encoding="utf-8"?>

  • Creating a content management system for dedicated use

    - by whitstone86
    I've been trying to create a specialised CMS, as none of the current open-source ones fit my needs for this project. I did my research on Google, tried multiple times but haven't got very far with this project. I'm trying to create a CMS for a TV/episode guide which is similar to this: (for some that don't have the :// just copy-and-paste and add it after http in the URL) http library.digiguide.com/lib/programmenextshowing/Police%2C+Camera%2C+Action!-12578 (one such example) - where records expire and delete from the database after expiration. This is the design I'm trying to emulate: http library.digiguide.com/lib/programme/24-84241/Drama/ - the programme http://library.digiguide.com/lib/episode/Under+Surveillance-714873 - a typical episode, could use .htaccess to remove php from name http library.digiguide.com/lib/programmenextshowing/24-84241 - paginated episode display (using script that I found in search here possibly) I don't have access to cron job as it's on Windows/Apache, so that's out the question for this one. I'm not sure how to go about this successfully, anyone got any advice? (Note:Although the linked site runs in ASP.NET, it's the design and feel of it I'm trying to emulate, except in PHP. I've managed to emulate that site's design, but with my own tweaks to it.)

  • Creating GUI using XML file in C#

    - by Gal Goldman
    How can I create automatic GUI using XML file in C#? Should I write a parser for the file and define a sort of "protocol" for the file's structure, and after the parse - create the GUI controls manually (respective to the data in the files)? Or is there a better way? Is there a tool, or a built-in code in the .NET environment which can do that for me automatically? (I am currently working with win forms, but I am willing to consider any other technology - as long as it's supported in MONO, since the code should be portable to Linux as well).

  • [javascript - jQuery] creating nested array's on the fly

    - by adardesign
    What i am trying to do is to loop this HTML and get an nested array of this HTML values that i want to grab. This script is just part of a whole function. html <div class="configureData"> <div title="Large"> <a href="yellow" title="true" rel="$55.00" name="sku22828"></a> <a href="green" title="true" rel="$55.00" name="sku224438"></a> <a href="Blue" title="true" rel="$55.00" name="sku22222"></a> </div> <div title="Large"> <a href="yellow" title="true" rel="$55.00" name="sku22828"></a> <a href="green" title="true" rel="$55.00" name="sku224438"></a> <a href="Blue" title="true" rel="$55.00" name="sku22222"></a> </div> <div title="Large"> <a href="yellow" title="true" rel="$55.00" name="sku22828"></a> <a href="green" title="true" rel="$55.00" name="sku224438"></a> <a href="Blue" title="true" rel="$55.00" name="sku22222"></a> </div> </div> javascript // this is part of a script..... parseData:function(dH){ dH.find(".configureData div").each(function(indA, eleA){ colorNSize.tempSizeArray[indA] = [eleA.title,[],[],[],[]] $(eleZ).find("a").each(function(indB, eleB){ colorNSize.tempSizeArray[indA][indB+1] = eleC.title }) }) }, I expect the end array should look like this. [ ["large", ["yellow", "green", "blue"], ["true", "true", "true"], ["$55", "$55","$55"] ], ["Medium", ["yellow", "green", "blue"], ["true", "true", "true"], ["$55", "$55","$55"] ] ] // and so on....

  • Phantomjs creating black output from SVG using page.render

    - by Neil Young
    I have been running PhantomJS 1.9.6 happily on a turnkey Linux server for about 4 months now. Its purpose is to take an SVG file and create different sizes using the page.render function. This has been doing this but since a few days ago has started to generate a black mono output. Please see below: The code: var page = require('webpage').create(), system = require('system'), address, output, ext, width, height; if ( system.args.length !== 4 ) { console.log("{ \"result\": false, \"message\": \"phantomjs.rasterize: error need address, output, extension arguments\" }"); //console.log('phantomjs.rasterize: error need address, output, extension arguments'); phantom.exit(1); } else if( system.args[3] !== "jpg" && system.args[3] !== "png"){ console.log("{ \"result\": false, \"message\": \"phantomjs.rasterize: error \"jpg\" or \"png\" only please\" }"); //console.log('phantomjs.rasterize: error "jpg" or "png" only please'); phantom.exit(1); } else { address = system.args[1]; output = system.args[2]; ext = system.args[3]; width = 1044; height = 738; page.viewportSize = { width: width, height: height }; //postcard size page.open(address, function (status) { if (status !== 'success') { console.log("{ \"result\": false, \"message\": \"phantomjs.rasterize: error loading address ["+address+"]\" }"); //console.log('phantomjs.rasterize: error loading address ['+address+'] '); phantom.exit(); } else { window.setTimeout(function () { //--> redner full size postcard page.render( output + "." + ext ); //--> redner smaller postcard page.zoomFactor = 0.5; page.clipRect = {top:0, left:0, width:width*0.5, height:height*0.5}; page.render( output + ".50." + ext); //--> redner postcard thumb page.zoomFactor = 0.25; page.clipRect = {top:0, left:0, width:width*0.25, height:height*0.25}; page.render( output + ".25." + ext); //--> exit console.log("{ \"result\": true, \"message\": \"phantomjs.rasterize: success ["+address+"]>>["+output+"."+ext+"]\" }"); //console.log('phantomjs.rasterize: success ['+address+']>>['+output+'.'+ext+']'); phantom.exit(); }, 100); } }); } Does anyone know what can be causing this? There have been no server configuration changes that I know of. Many thanks for your help.

  • Creating queries using Criteria API (JPA 2.0)

    - by Pym
    Hello there ! I'm trying to create a query with the Criteria API from JPA 2.0, but I can't make it work. The problem is with the "between" conditionnal method. I read some documentation to know how I have to do it, but since I'm discovering JPA, I don't understand why it does not work. First, I can't see "creationDate" which should appear when I write "Transaction_." I thought it was maybe normal, since I read the metamodel was generated at runtime, so I tried to use 'Foo_.getDeclaredSingularAttribute("value")' instead of 'Foo_.value', but it still doesn't work at all. Here is my code : public List<Transaction> getTransactions(Date startDate, Date endDate) { EntityManager em = getEntityManager(); try { CriteriaBuilder cb = em.getCriteriaBuilder(); CriteriaQuery<Transaction> cq = cb.createQuery(Transaction.class); Metamodel m = em.getMetamodel(); EntityType<Transaction> Transaction_ = m.entity(Transaction.class); Root<Transaction> transaction = cq.from(Transaction.class); // Error here. cannot find symbol. symbol: variable creationDate cq.where(cb.between(transaction.get(Transaction_.creationDate), startDate, endDate)); // I also tried this: // cq.where(cb.between(Transaction_.getDeclaredSingularAttribute("creationDate"), startDate, endDate)); List<Transaction> result = em.createQuery(cq).getResultList(); return result; } finally { em.close(); } } Can someone help me to figure this out? Thanks.

  • Creating a new nested resource

    - by Bobby B
    I'm working on a basic garden logging application which consists of gardens, plants and planted plants. Each user has one or many gardens, plants are master definitions, and a planted plant can be thought of as an instance of a plant in a specific user's garden. In my routes.rb file I have the following: map.resources :gardens do |gardens| gardens.resources :planted_plants, :has_many => :plant_log_entries, :collection => { :filter => :post, :choose_garden => :post} gardens.resources :garden_log_entries end map.resources :plants This makes sense to me when retrieving a list of planted_plants in a user's garden, but I'd like to create a planted_plant record from the index of plant. The problem is, a user can have multiple gardens. How can I create a new form for a planted_plant that allows the user to specify which garden should be used? The current route requires a garden_id - which makes sense for retrieval, but I'd like to supply that as a parameter for creation. Thanks in advance for any help!

  • Creating a protected link

    Is there a way to create a protected download link which is random, expiry, requires a password and pointing to a specific file in C# that is associated with IIS 7.0? Several random links can link to the same file. Built-in codes or perhaps 3rd party libraries? For example, http://www.example.com/<some random gibberish>/<md5 of file>/file.jpg

  • Creating Graphs on an iPad/iPhone

    - by phantomdata
    I was wondering if anyone knew of a simple way to implement graphing in an iPhone/iPad application. I've spent quite a bit of time googling and can't seem to find any sort of a solution. Maybe I'm just searching with the wrong terms since a lot of consumers are asking about "graphing" in terms of using their applications, not developing them, the search-space is rather polluted. It seems like a lot of iPad/iPhone applications have embedded graphs... and I can't imagine that every developer has invented their own graphing engine from the ground up. Or, maybe they have... Does anyone have any suggestions?

  • Error while creating tests in Visual Studio

    - by Benjol
    When I try to generate a unit test for the following method (in a public static class) private static string[] GetFields(string line, char sep) { char[] totrim = { '"', ' ' }; return line.Split(sep).Select(col => col.Trim(totrim)).ToArray(); } The Tests output says: While trying to generate your tests, the following errors occurred: This method or property cannot be called within an event handler. It works if I make the function public - I've tried running Publicize.exe manually, it doesn't complain, but doesn't make any difference either.

  • Vbscript - Creating a script that mirrors several sets of folders

    - by Kenny Bones
    Ok, this is my problem. I'm doing a logonscript that basically copies Microsoft Word templates from a serverpath on to a local path of each computer. This is done using a check for group membership. If MemberOf(ObjGroupDict, "g_group1") Then oShell.Run "%comspec% /c %LOGONSERVER%\SYSVOL\mydomain.com\scripts\ROBOCOPY \\server\Templates\Group1\OFFICE2003\ " & TemplateFolder & "\" & " * /E /XO", 0, True End If Previously I used the /MIR switch of robocopy, which is exellent. But, if a user is member of more than one group, the /MIR switch removes the content from the first group, since it's mirroring the content from the second group. Meaning, I can't have both contents. This is "solved" by not using the /MIR switch and just let the content get copied anyway. BUT the whole idea of having the templates on a server is so that I can control the content the users receive through the script. So if I delete a file or folder from the server path, this doesn't replicate on the local computer. Since I don't use the /MIR switch anymore. Comprende? So, what do I do? I did a small script that basically checks the folders and files and then removes them accordingly, but this actually ended up being the same functionality as the /MIR switch anyway. How do I solve this problem? Edit: I've found that what I actually need is a routine that scans my local template folder for files and folders and checks if the same structure exists in any of the source template folders. The server template folders are set up like this: \\fileserver\templates\group1\ \\fileserver\templates\group2\ \\fileserver\templates\group3\ \\fileserver\templates\group4\ \\fileserver\templates\group5\ \\fileserver\templates\group6\ And the script that does the copying is structures like this (pseudo): If User is MemberOf (group1) Then RoboCopy.exe \\fileserver\templates\group1\ c:\templates\workgroup *.* /E /XO End if If User is MemberOf (group2) Then RoboCopy.exe \\fileserver\templates\group2\ c:\templates\workgroup *.* /E /XO End if If User is MemberOf (group3) Then RoboCopy.exe \\fileserver\templates\group3\ c:\templates\workgroup *.* /E /XO End if Etc etc With the /E switch, I make sure it copies subfolders as well. And the /XO switch only copies files and folders that are newer than those in my local path. But it doesn't consider if the local path contains files or folders that doesn't exist on the server template path. So after the copying is done, I would like to check if any of the files or folders on my c:\templates\workgroup actually exists in either of the sources. And if they don't, delete them from my local path. Something that could be combined in these memberchecks perhaps?
