  • iPhone - Create non-persistent entities in core data

    - by ncohen
    Hi everyone, I would like to use entity objects but not store them... I read that I could create them like this: myElement = (Element *)[NSEntityDescription insertNewObjectForEntityForName:@"Element" inManagedObjectContext:managedObjectContext]; And right after that remove them: [managedObjectContext deleteObject:myElement]; then I can use my elements: myElement.property1 = @"Hello"; This works pretty well even though I think this is probably not the most optimal way to do it... Then I try to use it in my UITableView... the problem is that the object get released after the initialization. My table becomes empty when I move it! Thanks edit: I've also tried to copy the element ([myElement copy]) but I get an error...

  • How to create a 'Hot or Not' website

    - by Casper
    Hi guys, I'd like to create a website with similar concept as 'Hot or Not' where users need to sign up to the website and then upload photos. Each photo can be given a description and some additional fields. Other users may comment and rate the photo entries. On top of that, users may favourite/bookmark (and remove) any photo entries and they're accessible via their profile page That's generally how the website will be. Can't decide on a CMS to use Somehow I'm at a crossroad here. I've done some research and found that Joomla has an extension that is able to pull this website off but the thing is I'm not that comfortable with using Joomla. I work with WordPress most of the time, but I can't seem to figure out how would I build this website with WordPress. Would using BuddyPress make it work? Would hiring a plugin developer to customize some plugins work? What do you guys think?

    - by avi cohen
    hello, i'm beginner at android development. i want to create an activity, which shows a question with 4 answers, and at the bottom of the screen i want to place a timer. i have already found timer example, and i created a question with the answers. the problem that they are 2 different projects and activities, and i am looking for the best way to implement it. i think i can't show 2 activities on one screen, but i can show 2 views or shell i use the ViewGroup, or maybe to copy-paste one of the activities code to another ( its the easiest way but probably the most ugliest way to implement it). please tell me what is the best way, that i will study and not to waste time to study all the ways and only then to choose one of them. thanks!

  • Edit and create nodes in a view?

    - by tputkonen
    We are storing people's class attendance information to Drupal. We would like to show this in a grid/chart, where the first column of each row shows person's name, and rest of the columns (ca. 20) either a checkbox or "X" if the user attended a class, or otherwise an non-checked box or empty column: (dates here) Jack X XXX X X Jill XX XXX XX It should also be possible to edit the attendance information on the grid. Each attendance information is a node of its own. This functionality can probably mostly be achieved using views and editablefields, but there is one problem: if a person has not attended a specific class he/she will not have at all an attendace node for that day. What would be the easiest way to create an attendace node in those cases, so that it would be possible for the end user to edit the grid by just clicking on the checkbox or typing an 'X'?

  • Does the pointer to free() have to point to beginning of the memory block, or can it point to the interior?

    - by Lambert
    The question is in the title... I searched but couldn't find anything. Edit: I don't really see any need to explain this, but because people think that what I'm saying makes no sense (and that I'm asking the wrong questions), here's the problem: Since people seem to be very interested in the "root" cause of all the problem rather than the actual question asked (since that apparently helps things get solved better, let's see if it does), here's the problem: I'm trying to make a D runtime library based on NTDLL.dll, so that I can use that library for subsystems other than the Win32 subsystem. So that forces me to only link with NTDLL.dll. Yes, I'm aware that the functions are "undocumented" and could change at any time (even though I'd bet a hundred dollars that wcstombs will still do the same exact thing 20 years from now, if it still exists). Yes, I know people (especially Microsoft) don't like developers linking to that library, and that I'll probably get criticized for the right here. And yes, those two points above mean that programs like chkdsk and defragmenters that run before the Win32 subsystem aren't even supposed to be created in the first place, because it's literally impossible to link with anything like kernel32.dll or msvcrt.dll and still have NT-native executables, so we developers should just pretend that those stages are meant to be forever out of our reaches. But no, I doubt that anyone here would like me to paste a few thousand lines of code and help me look through them and try to figure out why memory allocations that aren't failing are being rejected by the source code I'm modifying. So that's why I asked about a different problem than the "root" cause, even though that's supposedly known to be the best practice by the community. If things still don't make sense, feel free to post comments below! :)

  • How to return a string literal from a function

    - by skydoor
    Hi I am always confused about return a string literal or a string from a function. I was told that there might be memory leak because you don't know when the memory will be deleted? For example, in the code below, how to implement foo() so that make the output of the code is "Hello World"? void foo ( ) // you can add parameters here. { } int main () { char *c; foo ( ); printf ("%s",c); return 0; } Also if the return type of foo() is not void, but you can return char*, what should it be.

  • debugfs_create_file doesn't create file

    - by bala1486
    Hello, I am trying to create a debugfs file using the debugfs_create_file(...). I have written a sample code for this. static int __init mmapexample_module_init(void) { file1 = debugfs_create_file("mmap_example", 0644, NULL, NULL, &my_fops)\ ; printk(KERN_ALERT "Hello, World\n"); if(file1==NULL) { printk(KERN_ALERT "Error occured\n"); } if(file1==-ENODEV) { printk(KERN_ALERT "ENODEV occured\n"); } return 0; } When i ran insmod i could get the Hello, World message but no the error message. So i think the debugfs_create_file worked fine. However i couldn't find any file in /sys/kernel/debug. The folder is there but it is empty. Can anyone help me with this? Thank you... Thanks, Bala

  • call function from external js (php) file

    - by bah
    Hi, I have a file where I keep all scripts so my pages wouldn't get messy (I have php file which generates required javascript). My includes basically look like this: </html> <head> <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript" src="script.php"></script> </head> <body> <input type="button" onClick="return blah();" /> </body> </html> In script.php there's jquery wrapper $(document).ready where I keep all jquery related stuff. The funny thing is, when I put function blah() inside this wrapper I get "blah is not defined" error, but when I put it outside - works perfectly. So, what could be the problem?

  • Dynamically create labels in gas macros?

    - by pgod
    Hi everyone, I would like to dynamically create a set of labels in an assembly function using a gas macro. I would like to do something like this: .macro set_up_jumptab_entry prefix, from=0, to=10 .quad \prefix_\item .if \to-\from set_up_jumptab_entry \prefix,"(\from+1)",\to .endif .endm set_up_jumptab_entry myfunc 0 10 Here \prefix_\item would be something like myfunction_7. Now, I can find lots of examples of recursive invocation, but I haven't found one of just label concatenation involving passed-in macro arguments. Gas is quite poorly documented, so answering this question is difficult for me. Can you concatenate arguments to macros with other tokens to make single tokens? What's your favorite gas assembler reference?

  • Ms Excel Problem Linking Range in Source Document to Custom Function in Target Document

    - by user261935
    I have some customer MS Excel VBA code (MS Excel 2007) that takes a range as input and then does some work on it (it is quite a large range). I want to use a separate excel document as the source of the range data. If I have both the source and target document open then the function works just fine. If I have only the target document open I get #Value! returned and stepping through in the debugger I see "Error 2023" in the data value passed in. Any ideas how I make this work without having to open both spreadsheets simultaneously?

  • Create a Visual Studio type look using Java Swing

    - by JeffHeaton
    I would like to create extend a Java Swing application to have a look somewhat similar to an IDE such as Eclipse or Visual Studio. That’s, there would be a panel at the left that displays a tree, and a tab panel on the right that allows several elements of the tree to be opened and edited on right. For this I could easily use a BorderLayout and just use the center and left areas. However, I would also like to have the ability for the user to drag the border between these two panels, just like Eclipse and Visual Studio allow. I can think of several ways to do this, but was curious if anyone had found a particularly good way to do this, or knew of an example. I’ve googled for it, but have not found anything.

  • Are nested functions a bad thing in gcc ?

    - by LB
    Hi, I know that nested functions are not part of the standard C, but since they're present in gcc (and the fact that gcc is the only compiler i care about), i tend to use them quite often. Is this a bad thing ? If so, could you show me some nasty examples ? What's the status of nested functions in gcc ? Are they going to be removed ? thanks

  • django - order query set by postgres function

    - by thebiglife
    My initial question was here and was related to the postgres backend. http://stackoverflow.com/questions/2408965/postgres-subquery-ordering-by-subquery Now my problem has moved onwards to the Django ORM layer. I essentially want to order a query by a postgres function ('idx', taken from the above stackoverflow work) I've gone through trying to use model.objects.extra(order_by ) or simply order_by but I believe both of these need the order_by parameter to be an attribute or a field known to Django. I'm trying to think how to solve this without having to revert to using an entirely raw SQL query through a model manager.

  • Dynamically create PHPUnit tests from data-file

    - by DeletedAccount
    I have a data file with input and expected outputs. An example could be: input: output: 2 3 3 5 4 Exception 5 8 ... ... Currently I have a custom solution to read from the data file and perform a test for each {input,output} pair. I would like to convert this into a PHPUnit based solution and I would like to have one test per input using the test name forXassertY. So the first three tests would be called for2assert3(), for3assert5() and for4assertException(). I do not want to convert my existing data to tests if it's possible to create the test methods dynamically and keep the data file as the basis of these tests. I want to convert it to PHPUnit as I want to add some other tests later on and also process and view the output using Hudson. Suggestions?

  • Use of date function in PHP to output a user-friendly date

Here is a simplified version of the code I currently have: $result = mysql_query(" SELECT ListItem, DateAdded FROM lists WHERE UserID = '" . $currentid . "' "); while($row = mysql_fetch_array($result)) { // Make the date look nicer $dateadded = date('d-m-Y',$row['DateAdded']); echo $row['ListItem'] . ","; echo $dateadded; echo "<br />"; } Is the use of the date function the best way to output a user-friendly date? Thanks for taking a look,

  • Passing javascript form variables into jQuery function not working
