  • How to return this XML-RPC response in an array using PHP?

    - by mind.blank
    I'm trying to put together a WordPress plugin and I want to grab a list of all categories (of other WordPress blogs) via XML-RPC. I have the following code and it looks like it works so far: function get_categories($rpcurl,$username,$password){ $rpcurl2 = $rpcurl."/xmlrpc.php"; $params = array(0,$username,$password,true); $request = xmlrpc_encode_request('metaWeblog.getCategories',$params); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $rpcurl2); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: text/xml")); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_TIMEOUT, 10); curl_setopt($ch, CURLOPT_POSTFIELDS, $request); $results = curl_exec($ch); $res = xmlrpc_decode($results); curl_close($ch); return $res; } If I use $res I get the following string as the response: Array If I use $results then I get: categoryId17 parentId0 descriptionTest categoryDescription categoryNameTest htmlUrlhttp://test.yoursite.com/?cat=17 rssUrlhttp://test.yoursite.com/?feed=rss2&amp;cat=17 categoryId1 parentId0 descriptionUncategorized categoryDescription categoryNameUncategorized htmlUrlhttp://test.yoursite.com/?cat=1 rssUrlhttp://test.yoursite.com/?feed=rss2&amp;cat=1 I need to pull out the names after description so Uncategorized and Test in this case. It's my first time coding in PHP. I got these results by echoing them to the page, so not sure if they get changed in that process or not... By the way I modified the above code from one that posts to a WordPress blog remotely so maybe I haven't set some of the options correctly? With var_dump($res) I get: array(2) { [0]=> array(7) { ["categoryId"]=> string(2) "17" ["parentId"]=> string(1) "0" ["description"]=> string(4) "Test" ["categoryDescription"]=> string(0) "" ["categoryName"]=> string(4) "Test" ["htmlUrl"]=> string(40) "http://test.youreventwebsite.com/?cat=17" ["rssUrl"]=> string(54) "http://test.youreventwebsite.com/?feed=rss2&cat=17" } [1]=> array(7) { ["categoryId"]=> string(1) "1" ["parentId"]=> string(1) "0" ["description"]=> string(13) "Uncategorized" ["categoryDescription"]=> string(0) "" ["categoryName"]=> string(13) "Uncategorized" ["htmlUrl"]=> string(39) "http://test.youreventwebsite.com/?cat=1" ["rssUrl"]=> string(53) "http://test.youreventwebsite.com/?feed=rss2&cat=1" } }

  • Where do you put your unit test?

    - by soulmerge
    I have found several conventions to housekeeping unit tests in a project and I'm not sure which approach would be suitable for our next PHP project. I am trying to find the best convention to encourage easy development and accessibility of the tests when reviewing the source code. I would be very interested in your experience/opinion regarding each: One folder for productive code, another for unit tests: This separates unit tests from the logic files of the project. This separation of concerns is as much a nuisance as it is an advantage: Someone looking into the source code of the project will - so I suppose - either browse the implementation or the unit tests (or more commonly: the implementation only). The advantage of unit tests being another viewpoint to your classes is lost - those two viewpoints are just too far apart IMO. Annotated test methods: Any modern unit testing framework I know allows developers to create dedicated test methods, annotating them (@test) and embedding them in the project code. The big drawback I see here is that the project files get cluttered. Even if these methods are separated using a comment header (like UNIT TESTS below this line) it just bloats the class unnecessarily. Test files within the same folders as the implementation files: Our file naming convention dictates that PHP files containing classes (one class per file) should end with .class.php. I could imagine that putting unit tests regarding a class file into another one ending on .test.php would render the tests much more present to other developers without tainting the class. Although it bloats the project folders, instead of the implementation files, this is my favorite so far, but I have my doubts: I would think others have come up with this already, and discarded this option for some reason (i.e. I have not seen a java project with the files Foo.java and FooTest.java within the same folder.) Maybe it's because java developers make heavier use of IDEs that allow them easier access to the tests, whereas in PHP no big editors have emerged (like eclipse for java) - many devs I know use vim/emacs or similar editors with little support for PHP development per se. What is your experience with any of these unit test placements? Do you have another convention I haven't listed here? Or am I just overrating unit test accessibility to reviewers?

  • Are there compelling reasons not to use Groovy?

    - by Leonard H Martin
    I'm developing a LoB application in Java after a long absence from the platform (having spent the last 8 years or so entrenched in Fortran, C, a smidgin of C++ and latterly .Net). Java, the language, is not much changed from how I remember it. I like it's strengths and I can work around its weaknesses - the platform has grown and deciding upon the myriad of different frameworks which appear to do much the same thing as one another is a different story; but that can wait for another day - all-in-all I'm comfortable with Java. However, over the last couple of weeks I've become enamoured with Groovy, and purely from a selfish point of view: but not just because it makes development against the JVM a more succinct and entertaining (and, well, "groovy") proposition than Java (the language). What strikes me most about Groovy is its inherent maintainability. We all (I hope!) strive to write well documented, easy to understand code. However, sometimes the languages we use themselves defeat us. An example: in 2001 I wrote a library in C to translate EDIFACT EDI messages into ANSI X12 messages. This is not a particularly complicated process, if slightly involved, and I thought at the time I had documented the code properly - and I probably had - but some six years later when I revisited the project (and after becoming acclimatised to C#) I found myself lost in so much C boilerplate (mallocs, pointers, etc. etc.) that it took three days of thoughtful analysis before I finally understood what I'd been doing six years previously. This evening I've written about 2000 lines of Java (it is the day of rest, after all!). I've documented as best as I know how, but, but, of those 2000 lines of Java a significant proportion is Java boiler plate. This is where I see Groovy and other dynamic languages winning through - maintainability and later comprehension. Groovy lets you concentrate on your intent without getting bogged down on the platform specific implementation; it's almost, but not quite, self documenting. I see this as being a huge boon to me when I revisit my current project (which I'll port to Groovy asap) in several years time and to my successors who will inherit it and carry on the good work. So, are there any reasons not to use Groovy?

  • How to store array of NSManagedObjects in an NSManagedObject

    - by David Tay
    I am loading my app with a property list of data from a web site. This property list file contains an NSArray of NSDictionaries which itself contains an NSArray of NSDictionaries. Basically, I'm trying to load a tableView of restaurant menu categories each of which contains menu items. My property list file is fine. I am able to load the file and loop through the nodes structure creating NSEntityDescriptions and am able to save to Core Data. Everything works fine and expectedly except that in my menu category managed object, I have an NSArray of menu items for that category. Later on, when I fetch the categories, the pointers to the menu items in a category is lost and I get all the menu items. Am I suppose to be using predicates or does Core Data keep track of my object graph for me? Can anyone look at how I am loading Core Data and point out the flaw in my logic? I'm pretty good with either SQL and OOP by themselves, but am a little bewildered by ORM. I thought that I should just be able to use aggregation in my managed objects and that the framework would keep track of the pointers for me, but apparently not. NSError *error; NSURL *url = [NSURL URLWithString:@"http://foo.com"]; NSArray *categories = [[NSArray alloc] initWithContentsOfURL:url]; NSMutableArray *menuCategories = [[NSMutableArray alloc] init]; for (int i=0; i<[categories count]; i++){ MenuCategory *menuCategory = [NSEntityDescription insertNewObjectForEntityForName:@"MenuCategory" inManagedObjectContext:[self managedObjectContext]]; NSDictionary *category = [categories objectAtIndex:i]; menuCategory.name = [category objectForKey:@"name"]; NSArray *items = [category objectForKey:@"items"]; NSMutableArray *menuItems = [[NSMutableArray alloc] init]; for (int j=0; j<[items count]; j++){ MenuItem *menuItem = [NSEntityDescription insertNewObjectForEntityForName:@"MenuItem" inManagedObjectContext:[self managedObjectContext]]; NSDictionary *item = [items objectAtIndex:j]; menuItem.name = [item objectForKey:@"name"]; menuItem.price = [item objectForKey:@"price"]; menuItem.image = [item objectForKey:@"image"]; menuItem.details = [item objectForKey:@"details"]; [menuItems addObject:menuItem]; } [menuCategory setValue:menuItems forKey:@"menuItems"]; [menuCategories addObject:menuCategory]; [menuItems release]; } if (![[self managedObjectContext] save:&error]) { NSLog(@"An error occurred: %@", [error localizedDescription]); }

  • Two collections and a for loop. (Urgent help needed) Checking an object variable against an inputted

    - by Elliott
    Hi there, I'm relatively new to java, I'm certain the error is trivial. But can't for the life of me spot it. I have an end of term exam on monday and currently trying to get to grips with past papers! Anyway heregoes, in another method (ALGO_1) I search over elements of and check the value H_NAME equals a value entered in the main. When I attempt to run the code I get a null pointer exception, also upon trying to print (with System.out.println etc) the H_NAME value after each for loop in the snippet I also get a null statement returned to me. I am fairly certain that the collection is simply not storing the data gathered up by the Scanner. But then again when I check the collection size with size() it is about the right size. Either way I'm pretty lost and would appreciate the help. Main questions I guess to ask are: from the readBackground method is the data.add in the wrong place? is the snippet simply structured wrongly? oh and another point when I use System.out.println to check the Background object values name, starttime, increment etc they print out fine. Thanks in advance.(PS im guessing the formatting is terrible, apologies.) snippet of code: for(Hydro hd: hydros){ System.out.println(hd.H_NAME); for(Background back : backgs){ System.out.println(back.H_NAME); if(back.H_NAME.equals(hydroName)){ //get error here public static Collection<Background> readBackground(String url) throws IOException { URL u = new URL(url); InputStream is = u.openStream(); InputStreamReader isr = new InputStreamReader(is); BufferedReader b = new BufferedReader(isr); String line =""; Vector<Background> data = new Vector<Background>(); while((line = b.readLine())!= null){ Scanner s = new Scanner(line); String name = s.next(); double starttime = Double.parseDouble(s.next()); double increment = Double.parseDouble(s.next()); double sum = 0; double p = 0; double nterms = 0; while((s.hasNextDouble())){ p = Double.parseDouble(s.next()); nterms++; sum += p; } double pbmean = sum/nterms; Background SAMP = new Background(name, starttime, increment, pbmean); data.add(SAMP); } return data; } Edit/Delete Message

  • How to avoid my this facebook app api login page?

    - by user1035140
    I got a problem regrading with my apps which is once I go to my apps, it sure will show me a login page instead of allow page? it always display the login page 1st then only display allow page, I had tried other apps, if I am 1st time user, It sure will appear the allow page only, it did not show me the login page. my question is how to I avoid my login page direct go to allow page? here is my login page picture here is my apps link https://apps.facebook.com/christmas_testing/ here is my facebook php jdk api coding <?php $fbconfig['appid' ] = "XXXXXXXXXXXXX"; $fbconfig['secret'] = "XXXXXXXXXXXXX"; $fbconfig['baseUrl'] = "myserverlink"; $fbconfig['appBaseUrl'] = "http://apps.facebook.com/christmas_testing/"; if (isset($_GET['code'])){ header("Location: " . $fbconfig['appBaseUrl']); exit; } if (isset($_GET['request_ids'])){ //user comes from invitation //track them if you need header("Location: " . $fbconfig['appBaseUrl']); } $user = null; //facebook user uid try{ include_once "facebook.php"; } catch(Exception $o){ echo '<pre>'; print_r($o); echo '</pre>'; } // Create our Application instance. $facebook = new Facebook(array( 'appId' => $fbconfig['appid'], 'secret' => $fbconfig['secret'], 'cookie' => true, )); //Facebook Authentication part $user = $facebook->getUser(); $loginUrl = $facebook->getLoginUrl( array( 'scope' => 'email,publish_stream,user_birthday,user_location,user_work_history,user_about_me,user_hometown' ) ); if ($user) { try { // Proceed knowing you have a logged in user who's authenticated. $user_profile = $facebook->api('/me'); } catch (FacebookApiException $e) { //you should use error_log($e); instead of printing the info on browser d($e); // d is a debug function defined at the end of this file $user = null; } } if (!$user) { echo "<script type='text/javascript'>top.location.href = '$loginUrl';</script>"; exit; } //get user basic description $userInfo = $facebook->api("/$user"); function d($d){ echo '<pre>'; print_r($d); echo '</pre>'; } ?

  • Cast IEnumerable<Inherited> To IEnumerable<Base>

    - by david2342
    I'm trying to cast an IEnumerable of an inherited type to IEnumerable of base class. Have tried following: var test = resultFromDb.Cast<BookedResource>(); return test.ToList(); But getting error: You cannot convert these types. Linq to Entities only supports conversion primitive EDM-types. The classes involved look like this: public partial class HistoryBookedResource : BookedResource { } public partial class HistoryBookedResource { public int ResourceId { get; set; } public string DateFrom { get; set; } public string TimeFrom { get; set; } public string TimeTo { get; set; } } public partial class BookedResource { public int ResourceId { get; set; } public string DateFrom { get; set; } public string TimeFrom { get; set; } public string TimeTo { get; set; } } [MetadataType(typeof(BookedResourceMetaData))] public partial class BookedResource { } public class BookedResourceMetaData { [Required(ErrorMessage = "Resource id is Required")] [Range(0, int.MaxValue, ErrorMessage = "Resource id is must be an number")] public object ResourceId { get; set; } [Required(ErrorMessage = "Date is Required")] public object DateFrom { get; set; } [Required(ErrorMessage = "Time From is Required")] public object TimeFrom { get; set; } [Required(ErrorMessage = "Time to is Required")] public object TimeTo { get; set; } } The problem I'm trying to solve is to get records from table HistoryBookedResource and have the result in an IEnumerable<BookedResource> using Entity Framework and LINQ. UPDATE: When using the following the cast seams to work but when trying to loop with a foreach the data is lost. resultFromDb.ToList() as IEnumerable<BookedResource>; UPDATE 2: Im using entity frameworks generated model, model (edmx) is created from database, edmx include classes that reprecent the database tables. In database i have a history table for old BookedResource and it can happen that the user want to look at these and to get the old data from the database entity framework uses classes with the same name as the tables to receive data from db. So i receive the data from table HistoryBookedResource in HistoryBookedResource class. Because entity framework generate the partial classes with the properties i dont know if i can make them virtual and override. Any suggestions will be greatly appreciated.

  • Building a DataTable in C# with one column at a time

    - by Awaken
    I am trying to build a Retirement Calculator as a chance to make something useful and learn C# better. Currently, I am trying to build a DataTable with a dynamic amount of rows/columns. For context, I ask the user for some inputs regarding salary, % of salary being invested, and expected ROI. I have some other stuff too, but it isn't really part of the issue I am having. Because the number of columns I need for the DataTable is unknown until the formula is run (while+for loop completes), I am having trouble doing things as DataColumns. Hopefully the code below will help. I am really trying to build the table one column at a time. I realize I could reverse it to build it one row at a time because the Years before retirement (yearsRetire) is known, but I would prefer not to and I want to learn more. Sorry for the indentation and commenting. I tried to leave some of my commented coding attempts in there. Thanks for any help. public double calcROI() { double testROI = 0.00; double tempRetireAmount = 0; double adjustRetire = goalAmount * (1 + (Math.Pow(inflation,yearsRetire))); // Loop through ROI values until the calculated retire amount with the test ROI // is greater than the target amount adjusted for inflation while (tempRetireAmount < adjustRetire) { //Increment ROI by 1% per while iteration testROI += .01; //Make a new Column to hold the values for ROI for this while iteration //dtMain.Columns.Add(Convert.ToString(testROI)); //DataColumn tempdc = new DataColumn(Convert.ToString(testROI)); //Loop through the number of years entered by user and see the amount //at Retirement with current ROI for (int i = 0; i < yearsRetire; i++) { //Main formula to calculate amount after i years tempRetireAmount = (tempRetireAmount + salary*savingsPct) * (1 + testROI); // Add value for this year/ROI to table/column //DataRow dr = .NewRow(); //dr tempRetireAmount; //tempdc[i] = tempRetireAmount; } //Need to add column of data to my Main DataTable //dtMain.Rows.Add(dr); //dtMain.Columns.Add(tempdc); } return testROI; }

  • Move an object in the direction of a bezier curve?

    - by Sent1nel
    I have an object with which I would like to make follow a bezier curve and am a little lost right now as to how to make it do that based on time rather than the points that make up the curve. .::Current System::. Each object in my scene graph is made from position, rotation and scale vectors. These vectors are used to form their corresponding matrices: scale, rotation and translation. Which are then multiplied in that order to form the local transform matrix. A world transform (Usually the identity matrix) is then multiplied against the local matrix transform. class CObject { public: // Local transform functions Matrix4f GetLocalTransform() const; void SetPosition(const Vector3f& pos); void SetRotation(const Vector3f& rot); void SetScale(const Vector3f& scale); // Local transform Matrix4f m_local; Vector3f m_localPostion; Vector3f m_localRotation; // rotation in degrees (xrot, yrot, zrot) Vector3f m_localScale; } Matrix4f CObject::GetLocalTransform() { Matrix4f out(Matrix4f::IDENTITY); Matrix4f scale(), rotation(), translation(); scale.SetScale(m_localScale); rotation.SetRotationDegrees(m_localRotation); translation.SetTranslation(m_localTranslation); out = scale * rotation * translation; } The big question I have are 1) How do I orientate my object to face the tangent of the Bezier curve? 2) How do I move that object along the curve without just setting objects position to that of a point on the bezier cuve? Heres an overview of the function thus far void CNodeControllerPieceWise::AnimateNode(CObject* pSpatial, double deltaTime) { // Get object latest pos. Vector3f posDelta = pSpatial->GetWorldTransform().GetTranslation(); // Get postion on curve Vector3f pos = curve.GetPosition(m_t); // Get tangent of curve Vector3f tangent = curve.GetFirstDerivative(m_t); } Edit: sorry its not very clear. I've been working on this for ages and its making my brain turn to mush. I want the object to be attached to the curve and face the direction of the curve. As for movement, I want to object to follow the curve based on the time this way it creates smooth movement throughout the curve.

  • C++: incorrect swapping of nodes in linked list

    - by Dragon
    I have 2 simple structures: struct Address { char city[255]; }; typedef Address* AddressPtr; struct Person { char fullName[255]; Address* address; Person* next; }; typedef Person* PersonPtr; The Person structure forms the Linked list where new elements are added to the beginning of the list. What I want to do is to sort them by fullName. At first I tried to swap links, but I lost the beginning of the list and as a result my list was sorted partially. Then I decided to sort list by swapping the values of nodes. But I get strange results. For a list with names: Test3, Test2, Test1, I get Test3, Test3, Test3. Here is my sorting code: void sortByName(PersonPtr& head) { TaskPtr currentNode, nextNode; for(currentNode = head; currentNode->next != NULL; currentNode = currentNode->next) { for(nextNode = currentNode->next; nextNode != NULL; nextNode = nextNode->next) { if(strcmp(currentNode->fullName, nextNode->fullName) > 0) { swapNodes(currentNode, nextNode); } } } } void swapNodes(PersonPtr& node1, PersonPtr& node2) { PersonPtr temp_node = node2; strcpy(node2->fullName, node1->fullName); strcpy(node1->fullName, temp_node->fullName); strcpy(node2->address->city, node1->address->city); strcpy(node1->address->city, temp_node->address->city); } After the sorting completion, nodes values are a little bit strange. UPDATED This is how I swapped links void swapNodes(PersonPtr& node1, PersonPtr& node2) { PersonPtr temp_person; AddressPtr temp_address; temp_person = node2; node2 = node1; node1 = temp_person; temp_address = node2->address; node2->address = node1->address; node1->address = temp_address; }

  • Please help with very simple android widget button click. Getting very frustrated. :(

    - by Little Wendy
    I have poured over every example that I can find and I have gone through the official documentation from google. All I am trying to do is create a toast notification from a button click on a widget. I can get the widget (and button) to appear but I can't get my intent to fire. I have seen several examples that show doing this different ways but I just can't get it to work. I haven't felt this helpless with coding in a long time and I'm starting to feel dumb. This is what I have so far: public class simpleclick extends AppWidgetProvider { /** Called when the activity is first created. */ @Override public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { final int N = appWidgetIds.length; Toast.makeText(context, "doing on update", Toast.LENGTH_SHORT).show(); for (int i=0; i<N; i++) { int appWidgetId = appWidgetIds[i]; Intent intent = new Intent(context, simpleclick.class); intent.setAction("ham"); PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0); RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.main); views.setOnClickPendingIntent(R.id.Timm, pendingIntent); appWidgetManager.updateAppWidget(appWidgetId, views); } } //@Override public void onReceive(Context context, Intent intent) { // TODO Auto-generated method stub Toast.makeText(context, "action is: " + intent.getAction(), Toast.LENGTH_SHORT).show(); super.onReceive(context, intent); } } My manifest: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.tblabs.simpleclick" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <receiver android:name="simpleclick"> <intent-filter> <action android:name="android.appwidget.action.APPWIDGET_UPDATE" /> </intent-filter> <meta-data android:name="android.appwidget.provider" android:resource="@xml/simpleclick" /> </receiver> </application> <uses-sdk android:minSdkVersion="5" /> </manifest> I would appreciate some help!

  • Comments Parent-Child query with indentation

    - by poldoj
    I've been trying to retrieve comments to articles in a pretty common blog fashion way. Here's my sample code: -- ---------------------------- -- Sample Table structure for [dbo].[Comments] -- ---------------------------- CREATE TABLE [dbo].[Comments] ( [CommentID] int NOT NULL , [AddedDate] datetime NOT NULL , [AddedBy] nvarchar(256) NOT NULL , [ArticleID] int NOT NULL , [Body] nvarchar(4000) NOT NULL , [parentCommentID] int NULL ) GO -- ---------------------------- -- Sample Records of Comments -- ---------------------------- INSERT INTO [dbo].[Comments] ([CommentID], [AddedDate], [AddedBy], [ArticleID], [Body], [parentCommentID]) VALUES (N'1', N'2011-11-26 23:18:07.000', N'user', N'1', N'body', null); GO INSERT INTO [dbo].[Comments] ([CommentID], [AddedDate], [AddedBy], [ArticleID], [Body], [parentCommentID]) VALUES (N'2', N'2011-11-26 23:18:50.000', N'user', N'2', N'body', null); GO INSERT INTO [dbo].[Comments] ([CommentID], [AddedDate], [AddedBy], [ArticleID], [Body], [parentCommentID]) VALUES (N'3', N'2011-11-26 23:19:09.000', N'user', N'1', N'body', null); GO INSERT INTO [dbo].[Comments] ([CommentID], [AddedDate], [AddedBy], [ArticleID], [Body], [parentCommentID]) VALUES (N'4', N'2011-11-26 23:19:46.000', N'user', N'3', N'body', null); GO INSERT INTO [dbo].[Comments] ([CommentID], [AddedDate], [AddedBy], [ArticleID], [Body], [parentCommentID]) VALUES (N'5', N'2011-11-26 23:20:16.000', N'user', N'1', N'body', N'1'); GO INSERT INTO [dbo].[Comments] ([CommentID], [AddedDate], [AddedBy], [ArticleID], [Body], [parentCommentID]) VALUES (N'6', N'2011-11-26 23:20:42.000', N'user', N'1', N'body', N'1'); GO INSERT INTO [dbo].[Comments] ([CommentID], [AddedDate], [AddedBy], [ArticleID], [Body], [parentCommentID]) VALUES (N'7', N'2011-11-26 23:21:25.000', N'user', N'1', N'body', N'6'); GO -- ---------------------------- -- Indexes structure for table Comments -- ---------------------------- -- ---------------------------- -- Primary Key structure for table [dbo].[Comments] -- ---------------------------- ALTER TABLE [dbo].[Comments] ADD PRIMARY KEY ([CommentID]) GO -- ---------------------------- -- Foreign Key structure for table [dbo].[Comments] -- ---------------------------- ALTER TABLE [dbo].[Comments] ADD FOREIGN KEY ([parentCommentID]) REFERENCES [dbo].

I was looking for a method to display hierarchical comments to articles like it happens in blogs. [edit] The problem with this query is that I get duplicates because I couldn't figure out how to properly select the ArticleID which I want comments from to display. I'm also looking for a method that sorts children entries by date within a same level. An example of what I'm trying to accomplish could be something like: (ArticleID[post retrieved]) ------------------------- ------------------------- (Comments[related to the article id above]) first comment[no parent] --[first child to first comment] --[second child to first comment] ----[first child to second child comment to first comment] --[third child to first comment] ----[first child to third child comment to first comment] ------[(recursive child): first child to first child to third child comment to first comment] ------[(recursive child): second child to first child to third child comment to first comment] second comment[no parent] third comment[no parent] --[first child to third comment] I kinda got myself lost in all this mess...I appreciate any help or simpler ways to get this working. Thanks

  • Send invitation to any user of google chats (is it possible?)

    - by Gizzo
    Hi I try to realize simple code on perl which should just get/send messages from/to gtalk accounts. I use Net::XMPP::* modules. All works just fine for users, who are my friends (in my "buddy" list). But i can't send message to unknown user. I know, that for this case i must send an invitation first, but Net::XMPP::* don't provide this possibility. There is only one way to invite person - construct my own xml according to "XEP-0155 Stanza Session Negotiation" protocol. But this doesn't work correct. When i send xml to server, it returns error "service-unavailable". I send: <message to='[email protected]'> <sxde xmlns='http://jabber.org/protocol/sxde' xmlns:sxde='http://jabber.org/protocol/sxde#metadata' session='0AEF4278DC4B6577' id='b'> <negotiation> <invitation> <feature var='http://jabber.org/protocol/whiteboard' /> </invitation> </negotiation> </sxde> </message> before my message.

  • PHP problems when transfering code from Windows to OS X

    - by Makka95
    I have recently bought a new MacBook Pro. Before I had my MacBook Pro I was working on a website on my desktop computer. And now I want to transfer this code to my new MacBook Pro. The problem is that when I transfered the code (I put it on Dropbox and simply downloaded it on my MacBook Pro) I started to see lots of error messages in my PHP code. The error message I”m receiving is: Warning: Cannot modify header information - headers already sent by (output started at /some/file.php:1) in /some/file.php on line 23 I have done some research on this and it seems that this error is most frequently caused by a new line, simple whitespace or any output before the <?php sign. I have looked through all the places where I have cookies that are being sent in the HTTP request and also where I'm using the header() function. I haven’t detected any output or whitespace that possibly could interfere and cause this problem. Noteworthy is that the error always says that the output is started at line 1. Which got me thinking if there is some kind of coding differences in the way that the Mac OS X and Windows operating systems handle new lines or white spaces? Or could the Dropbox transfer messed something up? The code on one of the sites(login.php) which produces the error: <?php include "mysql_database.php"; login(); $id = $_SESSION['Loggedin']; setcookie("login", $id, (time()+60*60*24*30)); header('Location: ' . $_SERVER['HTTP_REFERER']); ?> login function: function login() { $connection = connecttodatabase(); $pass = ""; $user = ""; $query = ""; if (isset($_POST['user']) && $_POST['user'] != null) { $user = $_POST['user']; if (isset($_POST['pass']) && $_POST['pass'] != null) { $pass = md5($_POST['pass']); $query = "SELECT ID FROM Anvandare WHERE Nickname='$user' AND Password ='$pass'"; } } if ($query != "") { $id = $connection->query($query); $id = mysqli_fetch_assoc($id); $id = $id['ID']; $_SESSION['Loggedin'] = $id; } closeconnection($connection); } Complete error: Warning: Cannot modify header information - headers already sent by (output started at /Users/name/GitHub/website/login.php:1) in /Users/namn/GitHub/website/login.php on line 9

  • PHP: csv generator creates extra field

    - by WhyKiki
    I'm coding a script that takes one csv file to transform it into another one. Basically, two foreach loops are used: one to iterate records and another to iterate fields. Certain fields (cno 25, 26, 44) for each record needs to be modified. The problem is that each modificatino creates an extra empty field, i.e. the code $colStr .= '"' . $col . '";'; works but not any of the code in the if statements. The code is: $rno = 0; foreach ($csvArray as $line) { $cno = 0; $colStr = ""; foreach ($line as $col) { if($rno>0 && $cno==25) { $stuff = array($csvArray[$rno][41], $csvArray[$rno][47], $csvArray[$rno][48], $csvArray[$rno][49]); foreach($stuff as &$value) { $value = preg_replace('/[^0-9]/', '', $value); } sort($stuff, SORT_NUMERIC); // Causes bug! $colStr .= '"' . $stuff[0] . '";'; } if($rno>0 && $cno==26) { $urls = ""; for($i = 55; $i<=62; $i++) { $urls .= "Images: " . $csvArray[$rno][$i] . " | "; } $urls .= "Some text: " . $csvArray[$rno][43] . " | "; // Causes bug! $colStr .= '"' . $urls . '";'; } if($rno>0 && $cno==44) { $colStr .= '"' . $_POST['location'][$rno] . '";'; } if($rno>0 && $cno==54) { $objType = $col; $objType = preg_replace('/foobar/i', '123', $objType); // Causes bug! $colStr .= '"' . $objType . '";'; } else { // This is ok, though $colStr .= '"' . $col . '";'; } $cno++; } $colStr = preg_replace('/;$/', '', $colStr); $colStr .= "\n"; fwrite($outputFile, $colStr); $rno++; } fclose($outputFile);

  • organizing unit test

    - by soulmerge
    I have found several conventions to housekeeping unit tests in a project and I'm not sure which approach would be suitable for our next PHP project. I am trying to find the best convention to encourage easy development and accessibility of the tests when reviewing the source code. I would be very interested in your experience/opinion regarding each: One folder for productive code, another for unit tests: This separates unit tests from the logic files of the project. This separation of concerns is as much a nuisance as it is an advantage: Someone looking into the source code of the project will - so I suppose - either browse the implementation or the unit tests (or more commonly: the implementation only). The advantage of unit tests being another viewpoint to your classes is lost - those two viewpoints are just too far apart IMO. Annotated test methods: Any modern unit testing framework I know allows developers to create dedicated test methods, annotating them (@test) and embedding them in the project code. The big drawback I see here is that the project files get cluttered. Even if these methods are separated using a comment header (like UNIT TESTS below this line) it just bloats the class unnecessarily. Test files within the same folders as the implementation files: Our file naming convention dictates that PHP files containing classes (one class per file) should end with .class.php. I could imagine that putting unit tests regarding a class file into another one ending on .test.php would render the tests much more present to other developers without tainting the class. Although it bloats the project folders, instead of the implementation files, this is my favorite so far, but I have my doubts: I would think others have come up with this already, and discarded this option for some reason (i.e. I have not seen a java project with the files Foo.java and FooTest.java within the same folder.) Maybe it's because java developers make heavier use of IDEs that allow them easier access to the tests, whereas in PHP no big editors have emerged (like eclipse for java) - many devs I know use vim/emacs or similar editors with little support for PHP development per se. What is your experience with any of these unit test placements? Do you have another convention I haven't listed here? Or am I just overrating unit test accessibility to reviewing developers?

  • Controlling the USB from Windows

    - by b-gen-jack-o-neill
    Hi, I know this probably is not the easiest thing to do, but I am trying to connect Microcontroller and PC using USB. I dont want to use internal USART of Microcontroller or USB to RS232 converted, its project indended to help me understand various principles. So, getting the communication done from the Microcontroller side is piece of cake - I mean, when I know he protocol, its relativelly easy to implement it on Micro, becouse I am in direct control of evrything, even precise timing. But this is not the case of PC. I am not very familiar with concept of Windows handling the devices connected. In one of my previous question I ask about how Windows works with devices thru drivers. I understood that for internal use of Windows, drivers must have some default set of functions available to OS. I mean, when OS wants to access HDD, it calls HDD driver (which is probably internal in OS), with specific "questions" so that means that HDD driver has to be written to cooperate with Windows, to have write function in the proper place to be called by the OS. Something similiar is for GPU, Even DirectX, I mean DirectX must call specific functions from drivers, so drivers must be written to work with DX. I know, many functions from WinAPI works on their own, but even "simple" window must be in the end written into framebuffer, using MMIO to adress specified by drivers. Am I right? So, I expected that Windows have internal functions, parts of WinAPI designed to work with certain comonly used things. To call manufacturer-designed drivers. But this seems to not be entirely true becouse Windows has no way to communicate thru Paralel port. I mean, there is no function in the WinAPI to work with serial port, but there are funcions to work with HDD,GPU and so. But now there comes the part I am getting very lost at. So, I think Windows must have some built-in functions to communicate thru USB, becouse for example it handles USB flash memory. So, is there any WinAPI function designed to let user to operate USB thru that function, or when I want to use USB myself, do I have to call desired USB-driver function myself? Becouse all you need to send to USB controller is device adress and the infromation right? I mean, I don´t have to write any new drivers, am I right? Just to call WinAPI function if there is such, or directly call original USB driver. Does any of this make some sense?

  • How to compare DateTime Objects while looping through a list?

    - by Taniq
    I'm trying to loop through a list (csv) containing two fields; a name and a date. There are various duplicated names and various dates in the list. I'm trying to deduce for each name in the list, where there are multiple instances of the same name, which corresponding date is the latest. I realise, from looking at another answer, that I need to use the DateTime.Compare method which is fine, but my problem is working out which date is later. Once I know this I need to produce a file with unique names and the latest date relating to it. This is my first question which makes me a newbie. EDIT: Initially I thought it would be 'ok' to set the LatestDate object to a date that wouldn't show up in my file, therefore making any later dates in the file the LatestDate. Here's my coding so far: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; namespace flybe_overwriter { class Program { static DateTime currentDate; static DateTime latestDate = new DateTime(1000,1,1); static HashSet<string> uniqueNames = new HashSet<string>(); static string indexpath = @"e:\flybe test\indexing.csv"; static string[] indexlist = File.ReadAllLines(indexpath); static StreamWriter outputfile = new StreamWriter(@"e:\flybe test\match.csv"); static void Main(string[] args) { foreach (string entry in indexlist) { uniqueNames.Add(entry.Split(',')[0]); } HashSet<string>.Enumerator fenum = new HashSet<string>.Enumerator(); fenum = uniqueNames.GetEnumerator(); while (fenum.MoveNext()) { string currentName = fenum.Current; foreach (string line in indexlist) { currentDate = new DateTime(Convert.ToInt32(line.Split(',')[1].Substring(4, 4)), Convert.ToInt32(line.Split(',')[1].Substring(2, 2)), Convert.ToInt32(line.Split(',')[1].Substring(0, 2))); if (currentName == line.Split(',')[0]) { if(DateTime.Compare(latestDate.Date, currentDate.Date) < 1) { // Console.WriteLine(currentName + " " + latestDate.ToShortDateString() + " is earlier than " + currentDate.ToShortDateString()); } else if (DateTime.Compare(latestDate.Date, currentDate.Date) > 1) { // Console.WriteLine(currentName + " " + latestDate.ToShortDateString() + " is later than " + currentDate.ToShortDateString()); } else if (DateTime.Compare(latestDate.Date, currentDate.Date) == 0) { // Console.WriteLine(currentName + " " + latestDate.ToShortDateString() + " is the same as " + currentDate.ToShortDateString()); } } } } } } } Any help appreciated. Thanks.

  • NSString cannot be released

    - by Stanley
    Consider the following method and the caller code block. The method analyses a NSString and extracts a "http://" string which it passes out by reference as an auto release object. Without releasing g_scan_result, the program works as expected. But according to non-arc rules, g_scan_result should be released since a retain has been called against it. My question are : Why g_scan_result cannot be released ? Is there anything wrong the way g_scan_result is handled in the posted coding below ? Is it safe not to release g_scan_result as long as the program runs correctly and the XCode Memory Leak tool does not show leakage ? Which XCode profile tools should I look into to check and under which subtitle ? Hope somebody knowledgeable could help. - (long) analyse_scan_result :(NSString *)scan_result target_url :(NSString **)targ_url { NSLog (@" RES analyse string : %@", scan_result); NSRange range = [scan_result rangeOfString:@"http://" options:NSCaseInsensitiveSearch]; if (range.location == NSNotFound) { *targ_url = @""; NSLog(@"fnd string not found"); return 0; } NSString *sub_string = [scan_result substringFromIndex : range.location]; range = [sub_string rangeOfString : @" "]; if (range.location != NSNotFound) { sub_string = [sub_string substringToIndex : range.location]; } NSLog(@" FND sub_string = %@", sub_string); *targ_url = sub_string; return [*targ_url length]; } The following is the caller code block, also note that g_scan_result has been declared and initialized (on another source file) as : NSString *g_scan_result = nil; Please do send a comment or answer if you have suggestions or find possible errors in code posted here (or above).

  • Issue with SQL query for activity stream/feed

    - by blabus
    I'm building an application that allows users to recommend music to each other, and am having trouble building a query that would return a 'stream' of recommendations that involve both the user themselves, as well as any of the user's friends. This is my table structure: Recommendations ID Sender Recipient [other columns...] -- ------ --------- ------------------ r1 u1 u3 ... r2 u3 u2 ... r3 u4 u3 ... Users ID Email First Name Last Name [other columns...] --- ----- ---------- --------- ------------------ u1 ... ... ... ... u2 ... ... ... ... u3 ... ... ... ... u4 ... ... ... ... Relationships ID Sender Recipient Status [other columns...] --- ------ --------- -------- ------------------ rl1 u1 u2 accepted ... rl2 u3 u1 accepted ... rl3 u1 u4 accepted ... rl4 u3 u2 accepted ... So for user 'u4' (who is friends with 'u1'), I want to query for a 'stream' of recommendations relevant to u4. This stream would include all recommendations in which either the sender or recipient is u4, as well as all recommendations in which the sender or recipient is u1 (the friend). This is what I have for the query so far: SELECT * FROM recommendations WHERE recommendations.sender IN ( SELECT sender FROM relationships WHERE recipient='u4' AND status='accepted' UNION SELECT recipient FROM relationships WHERE sender='u4' AND status='accepted') OR recommendations.recipient IN ( SELECT sender FROM relationships WHERE recipient='u4' AND status='accepted' UNION SELECT recipient FROM relationships WHERE sender='u4' AND status='accepted') UNION SELECT * FROM recommendations WHERE recommendations.sender='u4' OR recommendations.recipient='u4' GROUP BY recommendations.id ORDER BY datecreated DESC Which seems to work, as far as I can see (I'm no SQL expert). It returns all of the records from the Recommendations table that would be 'relevant' to a given user. However, I'm now having trouble also getting data from the Users table as well. The Recommendations table has the sender's and recipient's ID (foreign keys), but I'd also like to get the first and last name of each as well. I think I require some sort of JOIN, but I'm lost on how to proceed, and was looking for help on that. (And also, if anyone sees any areas for improvement in my current query, I'm all ears.) Thanks!

  • wxWidgets: Show a window that was marked hidden in the XRC

    - by jdwieber
    I'm new to wxWidgets and DialogBlocks. I have a form that is created using DialogBlocks and saved as an XRC file. Part of the form has a vertical wxStaticBoxSizer into which is placed two wxScrolledWindow elements. I want to only show one at a time based on what data is to be shown to the user, so I have one marked hidden and left the other one visible. In code (C++), when I try to switch the display and show the widget that was hidden in the XRC and hide the one that was not, the one that I hide goes away fine, but the one that I want to show is not visible. If I resize the window however, it appears. Once it has appeard then I can switch back and forth with no issues. I tried many combinations of showing, enabling, invalidating, getting the sizer and calling RecalcSizes, refresh, layout, and some others. I tried them in different combinations too. Simply calling Show will allow me to toggle between the two, but only after I switch to the one that does not show initially and resize the window. From what I see in the docs. the issue is that wxSizer doesn't allocate space for hidden windows, but there is a flag that can be set to override that behavor. My problem is that DialogBlocks does not expose that feature, so if I manually edit the XRC file the modifation will be lost when I, or one of the other devs. saves some changes. Is ther a sequence of calls that I can make to tell the sizer to allocate space? The default OnResize handler does something to cause the sizer to allocate space, but I don't know what that is, or how to do it. This is the flag I found in the docs: wxRESERVE_SPACE_EVEN_IF_HIDDEN Normally wxSizers don't allocate space for hidden windows or other items. This flag overrides this behavior so that sufficient space is allocated for the window even if it isn't visible. This makes it possible to dynamically show and hide controls without resizing parent dialog, for example. This function is new since wxWidgets version 2.8.8 Thanks in advance.
