  • Convert a complicated string into an array in php

    - by Patrick Beardmore
    I have a php variable that comes from a form that needs tidying up. I hope you can help. The variable contains a list of items (possibly two or three word items with a space in between words). I want to convert it to a comma separated list with no superfluous white space. I want the divisions to fall only at commas, semi-colons or new-lines. Blank cannot be an item. Here's a comprehensive example (with a deliberately messy input): Variable In: "dog, cat ,car,tea pot,, ,,, ;;(++NEW LINE++)fly, cake" Variable Out "dog,cat,car,tea pot,fly,cake" Can anyone help?

  • Is Core Animation causing my subviews to call -drawRect for every single frame?

    - by mystify
    I made a nice UIView subclass which paints all its stuff in -drawRect:, because people said that's good. That view is a subview of another. This another view is beeing animated with Core Animation: It's scaled down, rotated and moved. However, I encountered this: -drawRect seems to get called trillion of times during animation, and performance sucks. Is that normal or did I do something wrong, probably?

  • Best practice when working with web services that return objects?

    - by Raj
    Hello, I'm currently working with web services that return objects such as a list of files e.g. File array. I wanted to know whether its best practice to bind this type of object directly to my front end code for example a repeater/listview or whether to first parse it into my own list of "file class" e.g. customFiles[] If the web service changes then it will break my front end code, however if I create my own CustomFile class, then i would only need to change my code in one place to fix the issue, but it just seems like a lot of extra work to create the same classes from a web service, i wanted to know what is the best practice for this type of work. thanks Raj.

  • OpenSocial and its usages

    - by Paul Knopf
    I have looked for some explanation on the exact usages for the set of standards known as OpenSocial. I need some clarification if I can use OpenSocial like the following. I would like to create one library used to community with an OpenSocial api for use in my website that will not 'behave' like an application described by common sites like facebook and myspace. I'm not making a myspace of facebook application, I'm creating my own website and I want users to be able to find friends. I would like to allow users to store usernames and passwords for various OpenSocial-supported social networks. I would also like to use the api to sync events from my web site to their specified social network. I would also like to allow my users to view a list of friends and invite them. Is it possible to create one library that supports OpenSocial and simple "point" to and social network that supports it to get a list of friends and etc?

  • Autocomplete for generic types in Eclipse

    - by AvrDragon
    "Refer to objects by their interfaces" is a good practise, as mentioned in Effective Java. So for example i prefer List<String> al = new ArrayList<String>(); over ArrayList<String> al = new ArrayList<String>(); in my code. One annoying thing is that if i type ArrayList<String> al = new and then hit Ctrl+Space in Eclipse i get ArrayList<String>() as propostal. But if i type List al = new and then hit Ctrl+Space i will get only propostal to define anonymous inner class, but not propostals such as new ArrayList<String>(), what is 99% the case, or for example new Vector<String>(). Is there any way to get the subclasses as propostals for generic types?

  • What is a good naming convention to differentiate a class name from a property in C#?

    - by Andy Stampor
    I run into this frequently enough that I thought I'd see what others had to say about it. Using the StyleCop conventions, I find that I often have a property name that is hard to make different than the class name it is accessing. For example: public class ProjectManager { // Stuff here } public class OtherClass { private ProjectManager ProjectManager { get; set; } } It compiles and runs, but seems like it would be an easy way to confuse things, even with the use of "this".

  • How to display a tree of objects in a JTree?

    - by paul
    Imagine a collection of objects such as World, Country, Region and City. World contains a list of Country objects, Country contains a list of Region objects etc. I would like to represent this structure in a JTree and be able to add, remove and move objects around the tree. Can I easily create a TableModel from this structure? World would be the root object and I would need to perform some object-specific rendering. Any one know of an appropriate tutorial?

  • Wrong data retrieved from database

    - by holyredbeard
    So, I want to retrieve the order of the elements of a list. The order is set before by the user, and are stored in the table below. Because I also want to retrieve name and description of the list elements I need to combine two tables (see below). However, what is actually retrieved is an array containing 16 elements (should be four because it only exists four elements as for now). The array is too long to post here, but I put it in a phpFiddle to be found here if you're interested. Well, I have really tried to find what's wrong (probably something easy as always), but with no luck. Thanks a lot for your time and help! listModel.php: public function GetOrderedElements($userId, $listId) { // $userId = 46 // $listId = 1 $query = "SELECT le.listElemId, le.listElemName, le.listElemDesc, lo.listElemOrderPlace FROM listElement AS le INNER JOIN listElemOrder AS lo ON le.listId = lo.listId WHERE lo.userId = ? AND lo.listId = ? ORDER BY listElemId"; $stmt = $this->m_db->Prepare($query); $stmt->bind_param("ii", $userId, $listId); $listElements = $this->m_db->GetOrderedElements($stmt); return $listElements; } database.php: public function GetOrderedElements(\mysqli_stmt $stmt) { if ($stmt === FALSE) { throw new \Exception($this->mysqli->error); } if ($stmt->execute() == FALSE) { throw new \Exception($this->mysqli->error); } if ($stmt->bind_result($listElemId, $listElemName, $listElemDesc, $listElemOrderPlace) == FALSE) { throw new \Exception($this->mysqli->error); } $listElements = array(); while ($stmt->fetch()) { $listElements[] = array('listElemId' => $listElemId, 'listElemName' => $listElemName, 'listElemDesc' => $listElemDesc, 'listElemOrderPlace' => $listElemOrderPlace); } var_dump($listElements); $stmt->Close(); return $listElements; } from the database: listElemOrder: listElemOrderId | listId | listElemId | userId | listElemOrderPlace 1 1 1 46 1 2 1 2 46 4 3 1 3 46 2 4 1 4 46 3 listElement: listElemId | listElemName | listId | listElemDesc | listElemOrderPlace 1 Elem A 1 Derp NULL 2 Elem B 1 Herp NULL 3 Elem C 1 Lorum NULL 4 Elem D 1 Ipsum NULL Note: 'listElemOrderPlace' in the table listElement is the final order of the elements (all users average), not to be mixed with the one with the same name in the other table, that's only a specific user's order of the list elements (which is the interesting one in this case).

  • Consolidating values in a junction table

    - by senloe
    I have the following schema: Parcels Segments SegmentsParcels ========= ========== ================= ParcelID SegmentID ParcelID ... Name SegmentID ... id A user of the data wants to consolidate Segments.Names and gave me a list of current Segment.Names mapped to new Segment.Names (all of which currently exist). So now I have this list in a temporary table with the currentID and newID to map to. What I want to do is update the SegmentID in SegmentsParcels based on this map. I could use the statement: update SegmentParcels set segmentID = [newID] from newsegments where segmentID = currentid but this will create some duplicates I have a unique constraint on ParcelID and SegmentID in SegmentParcels. What is the best way to go about this? I considered removing the constraint and then dealing with removing the duplicates (which I did at one point and could probably do again) but I was hoping there was a simpler way.

  • Jquery UI autocomplete header

    - by Kanaka
    I have a jQuery UI autocomplete (with custom styling) where I added an header. You can see it at work here: http://jsfiddle.net/fbonomi/wJWGV/ the header is added like this: function cComboboxOpen( event) { var s='.... header .....'; $("ul.ui-autocomplete[style*='block']").prepend(s); } it works, and it keeps the column-like form I need (the real data will also be in columns) BUT, I would like to have the header NOT scrolling away when you have a long, scrollable list (e.g if you type "a" in the list) I have seen another very similar question here: jQuery UI Autocomplete with fixed header But it hasn't been answered, and in its current form it does not work properly (the header is "fixed" even when one scrolls the page, for example) How can I avoid the header to scroll away?

  • Has anyone tried the "objectify" library for Google App Engine?

    - by Spines
    I was using JDO for my google app engine project but got fed up with the additional 5 seconds it adds to my cold start time. I was planning on just writing stuff directly to the database with the low level datastore api, but then I came accross the objectify project ( http://code.google.com/p/objectify-appengine/ ). Apparently its a super light wrapper above the low level api. Does anyone have experiences with this library that they could share?

  • Faking a UITableView selection

    - by John Smith
    I have a UITableView where a selection displays some cool stuff in another part of the display. I tried to fake a keypress by writing: NSIndexPath *ip = [NSIndexPath indexPathForRow: 1 inSection:0]; [tableView selectRowAtIndexPath:ip animated:NO scrollPosition:UITableViewScrollPositionTop ]; [self tableView:tableView didSelectRowAtIndexPath:ip]; However it seems the last line is not being run. How can I make it run?

  • What would be the best schema to store the 'address' for different entities?

    - by Cesar
    Suppose we're making a system where we have to store the addrees for buildings, persons, cars, etc. The address 'format' should be something like: State (From a State list) County (From a County List) Street (free text, like '5th Avenue') Number (free text, like 'Chrysler Building, Floor 10, Office No. 10') (Yes I don't live in U.S.A) What would be the best way to store that info: Should I have a Person_Address, Car_Address, ... Or the address info should be in columns on each entity, Could we have just one address table and try to link each row to a different entity? Or are there another 'better' way to handle this type of scenario? How would yo do it?

  • A question about Drupal Node and Views

    - by Sushi
    I have created an "Add Question" content-type node which lets users ask questions. The questions have a title, image attachment option, and the content. I am showing the questions which have image as a block by filtering it as "Content: Photofield - list True" in Views. This way, only the questions which have images attached to the question appear in this block. Photofield by the way is the content type. I want to create a new block which only shows the questions which have no attached image. I have done filtering this block view by keeping filters as "Content: Photofield - list False" but in vain. There's also some expose option and I did some messing around with it too without coming to the result I want. Can anyone help?

    - by knappy
    I cannot get scroll to work, here is the complete stuff: http://zed.mit.edu/scroll2/buc.php I'm trying to refresh the page while maintaining the scroll position of the iframe inside. I'd like to have an alert when I actively scroll the iframe, these two both fail: $(top).frames['#iframe_bucinid'].scroll(function() .... $('#iframe_bucinid').scroll(function() ... The page's iframe is defined as: <iframe class="inframe" src="bucin.php" name="bucin" id="iframe_bucinid"> Notice that getting the scrollTop works with top.frames['bucin'].document.body.scrollTop

  • How to force Share Intent to open a specific app?

    - by AndroidUser99
    I like share intent, it is perfect to open sharing apps with image and text parameters. But now i'm researching the way to force share intent to open a specific app from the list, with the paramters given to the share intent. This is my actual code, it shows the list of sharing apps installed on the phone. Please, can somedone tell me what i should add to the code to force for example official twitter app? and official faccebok app? Intent sharingIntent = new Intent(Intent.ACTION_SEND); Uri screenshotUri = Uri.parse("file:///sdcard/test.jpg"); sharingIntent.setType("image/*"); sharingIntent.putExtra(Intent.EXTRA_TEXT, "body text"); sharingIntent.putExtra(Intent.EXTRA_STREAM, screenshotUri); startActivity(Intent.createChooser(sharingIntent, "Share image using")); Thanks

  • IE 8 prompts user on "slow" jQuery script

    - by Jason
    I have a form with over 100 list items that I must reorder on submit. The following code works to reorder my list without any apparent problems in Firefox; however, IE prompts with the message "A script on this page is causing Internet Explorer to run slowly. If it continues to run, your computer may become unresponsive. Do you want to abort the script?" If the user clicks 'No', the script will work as expected. var listitems = $(form).find('li').get(); listitems.sort(function(a, b) { var compA = $(a).attr('id'); var compB = $(b).attr('id'); return (compA - compB); }); Any ideas on how to make this more efficient?

  • ASP ListView: How do I access the data that is databound to the rows?

    - by Robert
    I want to access the data that was databound to my list view when handling list view events such as: protected void List_ItemDataBound(object sender, ListViewItemEventArgs e) or protected void List_ItemCommand(object sender, ListViewCommandEventArgs e) Inside the events, I can not access the data via somthing like Eval("ID") Currently we are using a very hacky solution: string id = e.Item.FindControl("lblID").Text; Where lblID is a hidden control that is populated with data in the aspx file using: <asp:Label ID="lblID" runat="server" Text='<%# Eval("ID") %>' /> My eyes bleed when I look at this, Is there a better way?

  • What does "the application failed to initialize properly" mean?

    - by Mason Wheeler
    I just got a bug report from someone running an app I wrote under Windows XP. He says it won't start up. The application failed to initialize properly (0xc0150002). Click on OK to terminate the application. It works fine at my end, (under Windows 7,) and I don't have any Win7- or Vista-specific stuff in the program, so it should work on XP too. How do I go about tracking this down and debugging it?

  • ASP .NET - What's going on behind an Eval() ?

    - by Amokrane
    Hi, I'm trying to understand how Eval() works for a specific purpose. I'm working on a project I don't really know and I need to read some data and put them in drop down list. These data are already read and are displayed inside an ItemTemplate. I noticed there are read using the Eval() method. Something like: <ItemTemplate> <a href="...=<%# Eval("foo") %>></a> </ItemTemplate> I need to know where Eval is getting these data from in order to discover where I should read them for my drop down list! But I didn't really understand how it works! I know that Eval() evaluates data binding expressions at runtime but where do you think I should take a look at? Thank you

  • Linq query with Array in where clause?

    - by Matt Dell
    I have searched for this, but still can't seem to get this to work for me. I have an array of Id's associated with a user (their Organization Id). These are placed in an int[] as follows: int[] OrgIds = (from oh in this.Database.OrganizationsHierarchies join o in this.Database.Organizations on oh.OrganizationsId equals o.Id where (oh.Hierarchy.Contains(@OrgId)) || (oh.OrganizationsId == Id) select o.Id).ToArray(); The code there isn't very important, but it shows that I am getting an integer array from a Linq query. From this, though, I want to run another Linq query that gets a list of Personnel, that code is as follows: List<Personnel> query = (from p in this.Database.Personnels where (search the array) select p).ToList(); I want to add in the where clause a way to select only the users with the OrganizationId's in the array. So, in SQL where I would do something like "where OrganizationId = '12' or OrganizationId = '13' or OrganizatonId = '17'." Can I do this fairly easily in Linq / .NET?
