• Conditional "Get Script File" in Javascript without using a library function

  - by Adam

  I work at a company that has many clients that have their own website that "plugs in" to our system. In other words they have their own website and they have a link that, when the user clicks it, transitions them over to our site. There is a feature that I want to track by giving the client a small block of code to put on their homepage. Whenever the homepage is loaded with a certain query string variable I want the block of code to request a file on my server. Then on the server I'll record the tracking info based on the query string. All this would be really easy if I can guarantee that the client would be using jQuery or some similar library, but there are a lot of clients and I can't really rely on them all using jQuery. At the same time I'd like to limit the size of the block of javascript code that they paste in. I think the best solution would be to have something like: if(querystring.substring("Tracking=") > 0) { include("blah.aspx?TrackingQS=" + querystring); } but I can't find a include function in built-in javascript without calling some library like jQuery. Any thoughts?? I could do straight up AJAX but I want to limit the number of lines of code for several reasons that I won't bore you with here.

• Calling javascript function from android webview?

  - by Edmond Tamas

  I try to call a javascript function from directly form my application (webview.apk), in order to start a script which would autoplay a html5 video clip, I have tried to add itt right after webview loadURL but wwithout luck. Maybe someone could take a look at the code. What am I missing? Thanks! package tscolari.mobile_sample; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.webkit.WebSettings; import android.webkit.WebView; import android.webkit.WebViewClient; import android.webkit.WebChromeClient; import android.media.MediaPlayer; public class InfoSpotActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); WebView mainWebView = (WebView) findViewById(R.id.mainWebView); WebSettings webSettings = mainWebView.getSettings(); webSettings.setJavaScriptEnabled(true); mainWebView.setWebChromeClient(new WebChromeClient()); mainWebView.setWebViewClient(new MyCustomWebViewClient()); mainWebView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY); mainWebView.loadUrl("http://server.info-spot.net"); mainWebView.loadUrl("javascript:playVideo()"); } private class MyCustomWebViewClient extends WebViewClient { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { view.loadUrl(url); return true; } } }

• Unobtrusive, self-hosted comments function to put onto existing web pages

  - by Pekka

  I am building a new site which will consist of a mix of dynamic and static pages. I would like to add commenting functionality to those pages with as little work as possible. I'm curious as to whether such a solution exists in PHP. The ideal set of features would be: Completely independent from the surrounding page / site: PHP code gets dropped into page, a page ID is added, done. Simple "write a comment" form Comments for each page are displayed using a PHP function Nice, clean output of <ul><li>.... that can be styled by the surrounding site Optional Captcha Optional Gravatar sensitivity Minimalistic administration area to moderate/delete comments, no ACL, can protect it using .htaccess The ideal integreation would be like this: <?php show_comments("my_page_name"); ?> this would 1. display a form to add a new comment that gets automatically associtated with my_page_name; and 2. display all comments that were made through this form using this ID. Does anybody know a solution like this? Bounty I am setting up a bounty because while there were some good suggestions, they all point to external services. I'm really curious to see whether there isn't anything self-hosted around. If this doesn't exist yet, it sure would be great to see as an Open Source project.

• Weird problem with string function

  - by wrongusername

  I'm having a weird problem with the following function, which returns a string with all the characters in it after a certain point: string after(int after, string word) { char temp[word.size() - after]; cout << word.size() - after << endl; //output here is as expected for(int a = 0; a < (word.size() - after); a++) { cout << word[a + after]; //and so is this temp[a] = word[a + after]; cout << temp[a]; //and this } cout << endl << temp << endl; //but output here does not always match what I want string returnString = temp; return returnString; } The thing is, when the returned string is 7 chars or less, it works just as expected. When the returned string is 8 chars or more, then it starts spewing nonsense at the end of the expected output. For example, the lines cout << after(1, "12345678") << endl; cout << after(1, "123456789") << endl; gives an output of: 7 22334455667788 2345678 2345678 8 2233445566778899 23456789?,?D~ 23456789?,?D~ What can I do to fix this error, and are there any default C++ functions that can do this for me?

• How to determine the size of a project (lines of code, function points, other)

  - by sixtyfootersdude

  How would you evaluate project size? Part A: Before you start a project. Part B: For a complete project. I am interested in comparing unrelated projects. Here are some options: 1) Lines of code. I know that this is not a good metric of productivity but is this a reasonable measure of project size? If I wanted to estimate how long it would take to recreate a project would this be a reasonable way to do it? How many lines of code should I estimate a day? 2) Function Points. Functions points are defined as the number of: inputs outputs inquires internal files external interfaces Anyone have a veiw point on whether this is a good measure? Is there a way to **actually do this? Does anyone have another solution? Hours taken seems like it could be a useful metric but not solely. If I ask you what is a "bigger program" and give you two programs how would you approach the question? I have seen several discussions of this on stackover flow but most discuss how to measure programmer productivity. I am more interested in project size.

• How to call a javascript function from one frame to another in Chrome/Webkit

  - by bambax

  I have developped an application that has a list of items in one frame; when one clicks on an item it does something in another frame (loads an image). This used to work fine in all browsers, including Chrome 3; now it still works fine in FF but in recent versions of Chrome (I believe since 4) it throws this error: Unsafe JavaScript attempt to access frame with URL (...) from frame with URL (...). Domains, protocols and ports must match. This is obviously a security "feature" but is it possible to get around it? Here is a simple test: index.html: <html> <frameset> <frame src="left.html" name="left"/> <frame src="right.html" name="right"/> </frameset> </html> left.html: <html> <body> <a href="javascript:parent.right.test('hello');">click me</a> </body> </html> right.html: <html> <body> <script> function test(msg) { alert(msg); } </script> </body> </html> The above works in FF 3.6 and Chrome 3 but in Chrome 5 it throws the above error...

• How to calculate this string-dissimilarity function efficiently?

  - by ybungalobill

  Hello, I was looking for a string metric that have the property that moving around large blocks in a string won't affect the distance so much. So "helloworld" is close to "worldhello". Obviously Levenshtein distance and Longest common subsequence don't fulfill this requirement. Using Jaccard distance on the set of n-grams gives good results but has other drawbacks (it's a pseudometric and higher n results in higher penalty for changing single character). [original research] As I thought about it, what I'm looking for is a function f(A,B) such that f(A,B)+1 equals the minimum number of blocks that one have to divide A into (A1 ... An), apply a permutation on the blocks and get B: f("hello", "hello") = 0 f("helloworld", "worldhello") = 1 // hello world -> world hello f("abba", "baba") = 2 // ab b a -> b ab a f("computer", "copmuter") = 3 // co m p uter -> co p m uter This can be extended for A and B that aren't necessarily permutations of each other: any additional character that can't be matched is considered as one additional block. f("computer", "combuter") = 3 // com uter -> com uter, unmatched: p and b. Observing that instead of counting blocks we can count the number of pairs of indices that are taken apart by a permutation, we can write f(A,B) formally as: f(A,B) = min { C(P) | P:|A|?|B|, P is bijective, ?i?dom(P) A[P(i)]=B[P(i)] } C(P) = |A| + |B| - |dom(P)| - |{ i | i,i+1?dom(P) and P(i)+1=P(i+1) }| - 1 The problem is... guess what... ... that I'm not able to calculate this in polynomial time. Can someone suggest a way to do this efficiently? Or perhaps point me to already known metric that exhibits similar properties?

• Help with GetGlyphOutline function(WinAPI)

  - by user146780

  I want to use this function to get contours and within these contours, I want to get cubic bezier. I think I have to call it with GGO_BEZIER. What puzzles me is how the return buffer works. "A glyph outline is returned as a series of one or more contours defined by a TTPOLYGONHEADER structure followed by one or more curves. Each curve in the contour is defined by a TTPOLYCURVE structure followed by a number of POINTFX data points. POINTFX points are absolute positions, not relative moves. The starting point of a contour is given by the pfxStart member of the TTPOLYGONHEADER structure. The starting point of each curve is the last point of the previous curve or the starting point of the contour. The count of data points in a curve is stored in the cpfx member of TTPOLYCURVE structure. The size of each contour in the buffer, in bytes, is stored in the cb member of TTPOLYGONHEADER structure. Additional curve definitions are packed into the buffer following preceding curves and additional contours are packed into the buffer following preceding contours. The buffer contains as many contours as fit within the buffer returned by GetGlyphOutline." I'm really not sure how to access the contours. I know that I can change a pointer another type of pointer but i'm not sure how I go about getting the contours based on this documentation. Thanks

• Returning object from function

  - by brainydexter

  I am really confused now on how and which method to use to return object from a function. I want some feedback on the solutions for the given requirements. Scenario A: The returned object is to be stored in a variable which need not be modified during its lifetime. Thus, const Foo SomeClass::GetFoo() { return Foo(); } invoked as: someMethod() { const Foo& l_Foo = someClassPInstance->GetFoo(); //... } Scneraio B: The returned object is to be stored in a variable which will be modified during its lifetime. Thus, void SomeClass::GetFoo(Foo& a_Foo_ref) { a_Foo_ref = Foo(); } invoked as: someMethod() { Foo l_Foo; someClassPInstance-GetFoo(l_Foo); //... } I have one question here: Lets say that Foo cannot have a default constructor. Then how would you deal with that in this situation, since we cant write this anymore: Foo l_Foo Scenario C: Foo SomeClass::GetFoo() { return Foo(); } invoked as: someMethod() { Foo l_Foo = someClassPInstance->GetFoo(); //... } I think this is not the recommended approach since it would incur constructing extra temporaries. What do you think ? Also, do you recommend a better way to handle this instead ?

• more problems with the LAG function is SAS

  - by SAS_learner

  The following bit of SAS code is supposed to read from a dataset which contains a numeric variable called 'Radvalue'. Radvalue is the temperature of a radiator, and if a radiator is switched off but then its temperature increases by 2 or more it's a sign that it has come on, and if it is on but its temperature decreases by 2 or more it's a sign that it's gone off. Radstate is a new variable in the dataset which indicates for every observation whether the radiator is on or off, and it's this I'm trying to fill in automatically for the whole dataset. So I'm trying to use the LAG function, trying to initialise the first row, which doesn't have a dif_radvalue, and then trying to apply the algorithm I just described to row 2 onwards. Any idea why the columns Radstate and l_radstate come out completely blank? Thanks everso much!! Let me know if I haven't explained the problem clearly. Data work.heating_algorithm_b; Input ID Radvalue; Datalines; 1 15.38 2 15.38 3 20.79 4 33.47 5 37.03 ; DATA temp.heating_algorithm_c; SET temp.heating_algorithm_b; DIF_Radvalue = Radvalue - lag(Radvalue); l_Radstate = lag(Radstate); if missing(dif_radvalue) then do; dif_radvalue = 0; radstate = "off"; end; else if l_Radstate = "off" & DIF_Radvalue > 2 then Radstate = "on"; else if l_Radstate = "on" & DIF_Radvalue < -2 then Radstate = "off"; else Radstate = l_Radstate; run;

• Getting wierd issue with TO_NUMBER function in Oracle

  - by Fazal

  I have been getting an intermittent issue when executing to_number function in the where clause on a varchar2 column if number of records exceed a certain number n. I used n as there is no exact number of records on which it happens. On one DB it happens after n was 1 million on another when it was 0.1. million. E.g. I have a table with 10 million records say Table Country which has field1 varchar2 containing numberic data and Id If I do a query as an example select * from country where to_number(field1) = 23 and id 1 and id < 100000 This works But if i do the query select * from country where to_number(field1) = 23 and id 1 and id < 100001 It fails saying invalid number Next I try the query select * from country where to_number(field1) = 23 and id 2 and id < 100001 It works again As I only got invalid number it was confusing, but in the log file it said Memory Notification: Library Cache Object loaded into SGA Heap size 3823K exceeds notification threshold (2048K) KGL object name :with sqlplan as ( select c006 object_owner, c007 object_type,c008 object_name from htmldb_collections where COLLECTION_NAME='HTMLDB_QUERY_PLAN' and c007 in ('TABLE','INDEX','MATERIALIZED VIEW','INDEX (UNIQUE)')), ws_schemas as( select schema from wwv_flow_company_schemas where security_group_id = :flow_security_group_id), t as( select s.object_owner table_owner,s.object_name table_name, d.OBJECT_ID from sqlplan s,sys.dba_objects d It seems its related to SGA size, but google did not give me much help on this. Does anyone have any idea about this issue with TO_NUMBER or oracle functions for large data?

• Passing an arbitrary JSONValue to a JSNI function

  - by Riley Lark

  I have a JSONValue in my Java that may be a JSONArray, a JSONObject, a JSONString, etc. I want to pass it to a JSNI function that can accept any of those types. If I naively write my JSNI as something like: public final native jsni(Object parameter) /*-{ doSomething(parameter); }-*/; public void useFunction(JSONValue value) { jsni(value); //Throws js exception at runtime :( } then I get a javascript exception, because GWT doesn't know how to convert the JSONValue to a JavaScriptObject (or native string / number value). My current workaround is public final native jsniForJSO(Object parameter) /*-{ doSomething(parameter); }-*/; public final native jsniForString(String parameter) /*-{ doSomething(parameter); }-*/; public final native jsniForNumber(double parameter) /*-{ doSomething(parameter); }-*/; public actuallyUseFunction(JSONValue value) { if (value.isObject()) { jsniForJSO(value.isObject().getJavaScriptObject()); } else if (value.isString()) { jsniForString(value.isString().stringValue()); } else { //etc } } This is a big burden for code maintainability, etc... especially if you have more than one parameter. Is there a way to generate these functions automatically, or get around this issue altogether? I've taken to wrapping everything in a JSONObject first, so I can definitely get a JavaScriptObject to pass to my jsni, but that's another clumsy mechanic.

• How to create a generic C free function .

  - by nomemory

  I have some C structures related to a 'list' data structure. They look like this. struct nmlist_element_s { void *data; struct nmlist_element_s *next; }; typedef struct nmlist_element_s nmlist_element; struct nmlist_s { void (*destructor)(void *data); int (*cmp)(const void *e1, const void *e2); unsigned int size; nmlist_element *head; nmlist_element *tail; }; typedef struct nmlist_s nmlist; This way I can have different data types being hold in "nmlist_element-data" . The "constructor" (in terms of OOP) has the following signature: nmlist *nmlist_alloc(void (*destructor)(void *data)); Where "destructor" is specific function that de-allocated "data" (being hold by the nmlist_element). If I want to have a list containing integers as data, my "destructor" would like this: void int_destructor(void *data) { free((int*)data); } Still i find it rather "unfriendly" for me to write a destructor functions for every simple primitive data type. So is there a trick to write something like this ? (for primitives): void "x"_destructor(void *data, "x") { free(("x" *)data); } PS: I am not a macro fan myself, and in my short experience regarding C, i don't use them, unless necessary.

• comma separated values in oracle function body

  I've got following oracle function but it does not work and errors out. I used Ask Tom's way to convert comma separated values to be used in select * from table1 where col1 in <> declared in package header: TYPE myTableType IS table of varchar2 (255); Part of package body: l_string long default iv_value_with_comma_separated|| ','; l_data myTableType := myTableType(); n NUMBER; begin begin LOOP EXIT when l_string is null; n := instr( l_string, ',' ); l_data.extend; l_data(l_data.count) := ltrim( rtrim( substr( l_string, 1, n-1 ) ) ); l_string := substr( l_string, n+1 ); END LOOP; end; OPEN my_cursor FOR select * from table_a where column_a in (select * from table (l_data)); CLOSE my_cursor END; above fails but it works fine when I remove select * from table (l_data) Can someone please tell me what I might be doing wrong here??

• Problem using the find function in MATLAB

  - by Peter Etchells

  I have two arrays of data that I'm trying to amalgamate. One contains actual latencies from an experiment in the first column (e.g. 0.345, 0.455... never more than 3 decimal places), along with other data from that experiment. The other contains what is effectively a 'look up' list of latencies ranging from 0.001 to 0.500 in 0.001 increments, along with other pieces of data. Both data sets are X-by-Y doubles. What I'm trying to do is something like... for i = 1:length(actual_latency) row = find(predicted_data(:,1) == actual_latency(i)) full_set(i,1:4) = [actual_latency(i) other_info(i) predicted_info(row,2) ... predicted_info(row,3)]; end ...in order to find the relevant row in predicted_data where the look up latency corresponds to the actual latency. I then use this to created an amalgamated data set, full_set. I figured this would be really simple, but the find function keeps failing by throwing up an empty matrix when looking for an actual latency that I know is in predicted_data(:,1) (as I've double-checked during debugging). Moreover, if I replace find with a for loop to do the same job, I get a similar error. It doesn't appear to be systematic - using different participant data sets throws it up in different places. Furthermore, during debugging mode, if I use find to try and find a hard-coded value of actual_latency, it doesn't always work. Sometimes yes, sometimes no. I'm really scratching my head over this, so if anyone has any ideas about what might be going on, I'd be really grateful.

• Prototype function to set onclick event observer in checkboxes

  Hi, I want to set an observer for each of the following checkboxes: <div id="listr"> <ul id="lr" style="list-style-type: none"> <p class="tir">Text 1</p> <li class="ro"><input type="checkbox" name="r1" id="r1"/>A1</li> <li class="ro"><input type="checkbox" name="r2" />A2</li> <p class="tir">Text 2</p> <li class="rubro"><input type="checkbox" name="r3" />B1</li> <p class="tir">Text 3</p> <li class="ro"><input type="checkbox" name="r4" />B2</li> </ul> </div> It works if I write one observer per checkbox, but I want to do it in a short fashion, so I need something like $$('listr.lr.li.input').invoke('observe',click,function(field) { alert(this.name + ' clicked ' + this.checked); // other stuff ... }); Which is not working Thanks in advance

• SWIG interface to receive an opaque struct reference in Java through function argument

  - by Beeo

  I am trying to use SWIG in order to use the Spotify API (libspotify) for Android: https://developer.spotify.com/technologies/libspotify/ I am having trouble defining the SWIG interface file to be able to successfully call the following native C function: sp_error sp_session_create(const sp_session_config * config, sp_session ** sess); Which in C would be called like this: //config struct defined previously sp_session *sess; sp_session_create(&config, &sess); But in Java I would need to call it like this: //config object defined previously sp_session javaSess = new sp_session(); sp_session_create(config, javaSess); sp_session is an opaque struct and is only defined in libspotify's API.h file as: typedef struct sp_session sp_session; I'm expecting the libspotify library to create it and give me a reference to it. The only thing I need that reference for then is to pass to other functions in the API. I believe the answer lies within the SWIG interface and typemaps, but I have been unsuccessful in trying to apply the examples I found in the documentation: http://www.swig.org/Doc2.0/SWIGDocumentation.html#Java_struct_pointer_pointer `http://www.swig.org/Doc2.0/SWIGDocumentation.html#Java_using_typemaps_return_arguments Help!

• Adding an Array inside an array in a PHP function

  - by bateman_ap

  I have created a function in PHP that calls a webservice and parses through the result, assinging values to variables and returning them all as an Array. This all works perfectly, however I have come across a need to have an "array within my array" I am assigning values as below: $productName = $product->Name; $productID = $product->ID; $productArray = array( 'productName' => "$productName", 'productID' => "$productID" ); return $productArray; However I now have a piece of data that comes back with multiple results so I need to have a additional array to store these, I am getting the values from the returned XML using a foreach loop, however I want to be able to add them to the array with a name so I can reference them in the returned data, this is where I have a problem... $bestForLists = $product->BestFors; foreach( $bestForLists as $bestForList ) { $productBestFors = $bestForList->BestFor; foreach( $productBestFors as $productBestFor ) { $productBestForName = $productBestFor->Name; $productBestForID = $productBestFor->ID; } } I tried creating an array for these using the below code: $bestForArray[] = (array( "productBestForID" => "$productBestForID", "productBestForName" => "$productBestForName" )); And then at the end merging these together: $productArray= array_merge($productArray,$bestForArray); If I print out the returned value I get: Array ( [productName] => Test Product [productID] => 14128 [0] => Array ( [productBestForID] => 56647 [productBestForName] => Lighting ) [1] => Array ( [productBestForID] => 56648 [productBestForName] => Sound ) ) I would like to give the internal Array a name so I can reference it in my code, or is there a better way of doing this, at the moment I am using the following in my PHP page to get values: $productName = $functionReturnedValues['productName']; I would like to use the following to access the array I could then loop through: $bestForArray = $functionReturnedValues['bestForArray']; Hope someone can help

• Using a function found in a different file in a loop

  - by Anders

  This question is related to BuddyPress, and a follow-up question from this question I have a .csv-file with 790 rows and 3 columns where the first column is the group name, second is the group description and last (third) the slug. As far as I've been told I can use this code: <?php $groups = array(); if (($handle = fopen("groupData.csv", "r")) !== FALSE) { while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) { $group = array('group_id' = 'SOME ID', 'name' = $data[0], 'description' = $data[1], 'slug' = groups_check_slug(sanitize_title(esc_attr($data[2]))), 'date_created' = gmdate( "Y-m-d H:i:s" ), 'status' = 'public' ); $groups[] = $group; } fclose($handle); } foreach ($groups as $group) { groups_create_group($group); } With http://www.nomorepasting.com/getpaste.php?pasteid=35217 which is called bp-groups.php. The thing is that I can't make it work. I've created a new file with the code written above called groupgenerator.php uploaded the .csv file to the same folder and opened groupgenerator.php in my browser. But, i get this error: Fatal error: Call to undefined function groups_check_slug() in What am I doing wrong?

• Parsing HTML: Call to a member function > children() on a non-object

  - by sm56d

  Hello all, I was just helped with this question but I can't get it to move to the next block of HTML. $html = file_get_html('http://music.banadir24.com/singer/aasha_abdoo/247.html'); $urls = $html->find('table[width=100%] table tr'); foreach($urls as $url){ $song_name = $url->children(2)->plaintext; $url = $url->children(6)->children(0)->href; } It returns the list of the names of the first album (Deesco) but it does not continue to the next album (The Best Of Aasha)? It just gives me this error: Notice: Trying to get property of non-object in C:\wamp\www\test3.php on line 26 Fatal error: Call to a member function children() on a non-object in C:\wamp\www\test3.php on line 28 Why is this and how can I get it to continue to the next table element? I appreciate any help on this! Please note: This is legal as the songs are not bound by copyright and they are available to download freely, its just I need to download a lot of them and I can't sit there clicking a button all day. Having said that, its taken me an hour to get this far.

• Best solution for an StringToInt function in C#

  - by StefanE

  Hi, I were asked to do an StringToInt / Int.parse function on the white board in an job interview last week and did not perform very good but I came up with some sort of solution. Later when back home I made one in Visual Studion and I wonder if there are any better solution than mine below. Have not bothred with any more error handling except checking that the string only contains digits. private int StrToInt(string tmpString) { int tmpResult = 0; System.Text.Encoding ascii = System.Text.Encoding.ASCII; byte[] tmpByte = ascii.GetBytes(tmpString); for (int i = 0; i <= tmpString.Length-1; i++) { // Check whatever the Character is an valid digit if (tmpByte[i] > 47 && tmpByte[i] <= 58) // Here I'm using the lenght-1 of the string to set the power and multiply this to the value tmpResult += (tmpByte[i] - 48) * ((int)Math.Pow(10, (tmpString.Length-i)-1)); else throw new Exception("Non valid character in string"); } return tmpResult; }
