• Printing HTML blocks

  - by Lem0n

  I have a page with a few tables that I want to be printable. I want the following behaviour: 1) Add a page break if the next table fits in a single page, but won't fit in the current page (because of other stuff already printed on this page) 2) Print the "table header" again in case it's needed to break a table (I guess it's the default behaviour) Any ideas specially on the first issue? Maybe some CSS can help? I'll give on example. I have a page with 4 tables. All of them with 10 lines, except the third one, with 50 lines. The first and second goes on the first page. Since the third one won't fit in the same page, but will fit in a page alone, it's printed on a page alone... and then the forth table is printed on the third page (in case it doesn't fit together in the second page). But, if the third page had 300 lines and would be broke anyway, it could have started to be print in the first page.

• SOLVED: Lisp: macro calling a function works in interpreter, fails in compiler (SBCL + CMUCL)

  - by ttsiodras

  As suggested in a macro-related question I recently posted to SO, I coded a macro called "fast" via a call to a function (here is the standalone code in pastebin): (defun main () (progn (format t "~A~%" (+ 1 2 (* 3 4) (+ 5 (- 8 6)))) (format t "~A~%" (fast (+ 1 2 (* 3 4) (+ 5 (- 8 6))))))) This works in the REPL, under both SBCL and CMUCL: $ sbcl This is SBCL 1.0.52, an implementation of ANSI Common Lisp. ... * (load "bug.cl") 22 22 $ Unfortunately, however, the code no longer compiles: $ sbcl This is SBCL 1.0.52, an implementation of ANSI Common Lisp. ... * (compile-file "bug.cl") ... ; during macroexpansion of (FAST (+ 1 2 ...)). Use *BREAK-ON-SIGNALS* to ; intercept: ; ; The function COMMON-LISP-USER::CLONE is undefined. So it seems that by having my macro "fast" call functions ("clone","operation-p") at compile-time, I trigger issues in Lisp compilers (verified in both CMUCL and SBCL). Any ideas on what I am doing wrong and/or how to fix this?

• Calling functions from the Immediate Window during debugging -- advanced Visual Studio kung-fu test

  - by kizzx2

  I see some related questions have been asked, but they're either too advanced for me to grasp or lacking a step-by-step guide from start to finish (most of them end up being insider talk of their own experiment results). OK here it is, given this simple program: #include <stdio.h> #include <string.h> int main() { FILE * f; char buffer[100]; memset(buffer, 0, 100); fun(); f = fopen("main.cpp", "r"); fread(buffer, 1, 99, f); printf(buffer); fclose(f); return 0; } What it does is basically print itself (assume file name is main.cpp). Question How can I have it print another file, say foobar.txt without modifying the source code? It has something to do with running it through VS's, stepping through the functions and hijacking the FILE pointer right before fread() is called. No need to worry about leaking resources by calling fclose(). I tried the simple f = fopen("foobar.txt", "r") which gave CXX0017: Error: symbol "fopen" not found Any ideas?

• C# client to Java web service

  - by tomislavg

  I have received wsdl file from outside company. I'm using VS2005 c#. With wsdl.exe I have created class containing methods and types for the given web service. To connect to the service outside company requires that certificate from the smart card is inputed in the header. I think i have achieved this with service.ClientCertificates.Add("Path to exported cert" - at least for now, after probably later i will take it from Certificate Store When service is called there are three steps that are taken and visible by the Fidller(Web Debugging Proxy)). service is called on the url http://test.company.com/webservice.wsdl service redirects the request to certificate server and pin needs to be inputed to get cookie for the server service is again redirected to url http://test.company.com/webservice.wsdl At point 1. I can see that my request send to the server contains .... but at point 3. i can not see request` just a empty string. The exception is thrown Msg: Possible SOAP version mismatch: Envelope namespace http://schemas.xmlsoap.org/wsdl/ was unexpected. Expecting http://schemas.xmlsoap.org/soap/envelope/. Does somebody have an example how to connect to java web service with certificate and AlowRedirect enabled for the web service? Any ideas what i am doing wrong are more that welcome.

• Need help with WCF design

  - by Jason

  I have been tasked with creating a set of web services. We are a Microsoft shop, so I will be using WCF for this project. There is an interesting design consideration that I haven't been able to figure out a solution for yet. I'll try to explain it with an example: My WCF service exposes a method named Foo(). 10 different users call Foo() at roughly the same time. I have 5 special resources called R1, R2, R3, R4, and R5. We don't really need to know what the resource is, other than the fact that a particular resource can only be in use by one caller at a time. Foo() is responsible to performing an action using one of these special resources. So, in a round-robin fashion, Foo() needs to find a resource that is not in use. If no resources are available, it must wait for one to be freed up. At first, this seems like an easy task. I could maybe create a singleton that keeps track of which resources are currently in use. The big problem is the fact that I need this solution to be viable in a web farm scenario. I'm sure there is a good solution to this problem, but I've just never run across this scenario before. I need some sort of resource tracker / provider that can be shared between multiple WCF hosts. Any ideas from the architects out there would be greatly appreciated!

• Trying to 'Make' CUDA SDK, ld cannot find library, ldconfig says it can.

  - by Andrew Bolster

  I know there are many other questions similar to this one, but none of the solutions posited there are working for me Basically, making the SDK sample files, i get /usr/bin/ld: cannot find -lcuda which would be an easy enough 'find the library and throw it to ldconfig', except ldconfig already says it has it... $ sudo ldconfig -v | grep cuda /usr/local/cuda/lib64: libcudartemu.so.3 -> libcudartemu.so.3.0.14 libcudart.so.3 -> libcudart.so.3.0.14 /usr/local/cuda/lib: libcudartemu.so.3 -> libcudartemu.so.3.0.14 libcudart.so.3 -> libcudart.so.3.0.14 libcuda.so.1 -> libcuda.so.195.36.15 libcuda.so.1 -> libcuda.so.195.36.15 libicudata.so.42 -> libicudata.so.42.1 And I checked, there is a symlink libcuda.so -> libcuda.so.1 but I'm still confused as to why libcuda.so -> ... doesnt show up I must be missing something really obvious. Any ideas?

• Can't empty JS array....

  - by solefald

  Yes, I am having issues with this very basic (or so it seems) thing. I am pretty new to JS and still trying to get my head around it, but I am pretty familiar with PHP and have never experienced anything like this. I just can not empty this damn array, and stuff keeps getting added to the end every time i run this. I have no idea why, and i am starting to think that it is somehow related to the way chekbox id's are named, but i may be mistaking.... id="alias[1321-213]", id="alias[1128-397]", id="alias[77-5467]" and so on. I have tried sticking checkboxes = []; and checkboxes.length = 0; In every place possible. Right after the beginning of the function, at the end of the function, even outside, right before the function, but it does not help, and the only way to empty this array is to reload the page. Please tell me what I am doing wrong, or at least point me to a place where i can RTFM. I am completely out of ideas here. function() { var checkboxes = new Array(); checkboxes = $(':input[name="checkbox"]'); $.each(checkboxes, function(key, value) { console.log(value.id); alert(value.id); } ); checkboxes.length = 0; } I have also read Mastering Javascript Arrays 3 times to make sure I am not doing something wrong, but still can't figure it out....

• Cleaning up a sparsebundle with a script

  - by nickg

  I'm using time machine to backup some servers to a sparse disk image bundle and I'd like to have a script to clean up the old back ups and re-size the image once space has been freed up. I'm fairly certain the data is protected because if I delete the old backups by right clicking, I have to enter a password to be able to delete them. To allow my script to be able to delete them, I've been running it as root. For some reason, it just won't run and every file it tries to delete I get rm: /file/: Operation not permitted Here is what I have as my script: #!/bin/bash for server in servername; do /usr/bin/hdiutil attach -mountpoint /path/to/mountpoint /path/to/sparsebundle/$server.sparsebundle/; /bin/sleep 10; /usr/bin/find /path/to/mountpoint -type d -mtime +7 -exec /bin/rm -rf {} \; /usr/bin/hdiutil unmount /path/to/mountpoint; /bin/sleep 10; /usr/bin/hdiutil compact /path/to/sparsebundle/$server.sparsebundle/; done exit; One of the problems I thought was causing this was it needed to have a mountpoint specified since the default mount was to /Volumes/Time\ Machine\ Backups/ that's why I created a mountpoint. I also thought that it was trying to delete the files to quickly after mounting and it wasn't actually mounted yet, that's why I added the sleep. I've also tried using the -delete option for find instead of -exec, but it didn't make any difference. Any help on this would be greatly appreciated because I'm out of ideas as to why this won't work.

• Button style in AlertDialogs

  - by Steve H

  Does anyone know how to override the default style for AlertDialog buttons? I've looked through the Android source for themes and styles and experimented with different things but I haven't been able to find a way that works. What I've got below works for changing the backgrounds, but doesn't do anything with the buttons. myTheme is applied to the whole <application> via the manifest. (Some other items were deleted for clarity, but they only relate to the title bar.) <style name="myTheme" parent="android:Theme"> <item name="android:buttonStyle">@style/customButtonStyle</item> <item name="android:alertDialogStyle">@style/dialogAlertTheme</item> </style> <style name="dialogAlertTheme" parent="@android:style/Theme.Dialog.Alert"> <item name="android:fullDark">@drawable/dialog_loading_background</item> <item name="android:topDark">@drawable/dialog_alert_top</item> <item name="android:centerDark">@drawable/dialog_alert_center</item> <item name="android:bottomDark">@drawable/dialog_alert_bottom</item> <!-- this last line makes no difference to the buttons --> <item name="android:buttonStyle">@style/customButtonStyle</item> </style> Any ideas?

• Colour manipulation of custom tags in niceEdit HTML editor ( JS / DOM )

  - by Chris

  Hi, I would like to be able to highlight, during typing and in real time, certain custom tags in the format #tag_name# within the text of a nicEdit instance ( http://nicedit.com/ ). My current attempt to implement as close to this as possible revolves around using the blur event of the editor to highlight the tags once the editor loses focus. I then use the following logic to wrap the tags in a span with a highlight class.. htmlEditor.addEvent( "blur", function( ) { str = nicEditors.findEditor( "html_content" ).getContent( ); // Remove existing spans first, leaving just the tag ( this could mess up if the html has been edited directly ) str = str.replace( /(<span class=\"highlight\">)(.[^<]+)(<\/span>)/gi, "$2" ); // Then wrap all instances of a particular tag with the highlight span str = str.replace( /#tag_name#/gi, "<span class='highlight'>#tag_name#</span>" ); nicEditors.findEditor( "html_content" ).setContent( str ); }); This is not ideal as my actual text now contains unwanted spans ( I only want the highlighting for the user's input experience, not to be saved to the database ). Obviously I could remove the spans before saving the text but the whole system is currently open to errors ( If the html is directly edited then other text may get highlighted etc ). What I would like to know is.. Is there any way to directly change the colour of the tags in the editor or DOM without using a mechanism such as this? Perhaps a way of colouring the text in memory rather than changing the HTML ? Any ideas ? Regards Chris P

• DatagGridViewColumn.DataPropertyName to an array element?

  - by unknown

  Hi there, I'm using a DataGridView binding its datasource to a List, and specifying the properties for each column. An example would be: DataGridViewTextBoxColumn colConcept = new DataGridViewTextBoxColumn(); DataGridViewCell cell4 = new DataGridViewTextBoxCell(); colConcept.CellTemplate = cell4; colConcept.Name = "concept"; colConcept.HeaderText = "Concept"; colConcept.DataPropertyName = "Concept"; colConcept.Width = 200; this.dataGridViewBills.Columns.Add(colConcept); {... assign other colums...} And finally this.dataGridViewBills.DataSource=billslist; //billslist is List<Bill> Obviously Class Bill has a Property called Concept, as well as one Property for each column. Well, now my problem, is that Bill should have and Array/List/whateverdynamicsizecontainer of strings called Years. Let's assume that every Bill will have the same Years.Count, but this only known at runtime.Thus, I can't specify properties like Bill.FirstYear to obtain Bill.Years[0], Bill.SecondYear to obtain Bills.Years[1]... etc... and bind it to each column. The idea, is that now I want to have a grid with dynamic number of colums (known at runtime), and each column filled with a string from the Bill.Years List. I can make a loop to add columns to the grid at runtime depending of Bill.Years.Count, but is possible to bind them to each of the strings that the Bill.Years List contains??? I'm not sure if I'm clear enough. The result ideally would be something like this, for 2 bills on the list, and 3 years for each bill: --------------------------------------GRID HEADER------------------------------- NAME CONCEPT YEAR1 YEAR2 YEAR3 --------------------------------------GRID VALUES------------------------------- Bill1 Bill1.Concept Bill1.Years[0] Bill1.Years[1] Bill1.Years[2] Bill2 Bill2.Concept Bill2.Years[0] Bill2.Years[1] Bill2.Years[2] I can always forget the datasource, and write each cell manually, as the MSFlexGrid used to like, but if possible, I would like to use the binding capabilities of the DataGridView. Any ideas? Thanks a lot.

• Problem with fork exec kill when redirecting output in perl

  - by Edu

  I created a script in perl to run programs with a timeout. If the program being executed takes longer then the timeout than the script kills this program and returns the message "TIMEOUT". The script worked quite well until I decided to redirect the output of the executed program. When the stdout and stderr are being redirected, the program executed by the script is not being killed because it has a pid different than the one I got from fork. It seems perl executes a shell that executes my program in the case of redirection. I would like to have the output redirection but still be able to kill the program in the case of a timeout. Any ideas on how I could do that? A simplified code of my script is: #!/usr/bin/perl use strict; use warnings; use POSIX ":sys_wait_h"; my $timeout = 5; my $cmd = "very_long_program 1>&2 > out.txt"; my $pid = fork(); if( $pid == 0 ) { exec($cmd) or print STDERR "Couldn't exec '$cmd': $!"; exit(2); } my $time = 0; my $kid = waitpid($pid, WNOHANG); while ( $kid == 0 ) { sleep(1); $time ++; $kid = waitpid($pid, WNOHANG); print "Waited $time sec, result $kid\n"; if ($timeout > 0 && $time > $timeout) { print "TIMEOUT!\n"; #Kill process kill 9, $pid; exit(3); } } if ( $kid == -1) { print "Process did not exist\n"; exit(4); } print "Process exited with return code $?\n"; exit($?); Thanks for any help.

• Community License Agreement for Commercial (SaaS) software?

  - by indomitablehef

  I've got a commercial SaaS application, an online collaboration/lean project mgmt tool. I want to offer a "Community Edition", with specific limitations on how the software can be used, for free. For example free for groups using it to manage open source projects free to K-12 teachers to use in the classroom free for authors collaborating on Lean/Kanban/AgileSoftwareDevelopment books and research papers. free for community conference organizers, user group organizers, etc. The license would grant use of the software with limitations. The software itself can enforce limitations on the number of users/projects. I'm looking for a license agreement / EULA that I can use to specify what uses the software can be used for (see above). It would restrict the users from using it in different ways, such as for commercial use, managing consulting projects, client work, etc. I've been combing the web for good examples of such agreements, and so far coming up short. Any ideas? To be clear, this would not be an open source license of any kind. It would cover the use of commercial software, for specific "community" uses, as we define them.

• Android maps out of memory error

  - by SamB09

  Hi , sometimes when running a google maps program with an overlay image i will receive a bit map out of memory error. It always seems to be at a random point in the app. Im not sure how to solve this. Anyone have any ideas ? My overlay code is below , im not sure if you need to see the class its called in though? public class MyOverlay2 extends Overlay { private static final double MAX_TAP_DISTANCE_KM = 3; // Rough approximation - one degree = 50 nautical miles private static final double MAX_TAP_DISTANCE_DEGREES = MAX_TAP_DISTANCE_KM * 0.5399568 * 50; private final GeoPoint gPoint; private final Context cont; private final int draw; // private final int lat; public MyOverlay2(Context cont, GeoPoint gPoint1, int draw) { // constructor will be called in the userLocation class to draw an overly image this.cont = cont; this.gPoint = gPoint1; this.draw = draw; } @Override public boolean draw(Canvas canvas, MapView mapView, boolean shadow, long when) { // constructor takes 3 arguments super.draw(canvas, mapView, shadow); // Convert geo coordinates to screen pixels Point screenPoint = new Point(); mapView.getProjection().toPixels(gPoint, screenPoint); //Read the image from the xml resource using a bitmap factory BitmapFactory.Options options=new BitmapFactory.Options(); options.inSampleSize = 1; Bitmap preview_bitmap=BitmapFactory.decodeResource(cont.getResources(),R.drawable.monday12,options); //draw the image at the location specified by the co-ordinates canvas.drawBitmap(preview_bitmap, screenPoint.x - preview_bitmap.getWidth() /2, screenPoint.y - preview_bitmap.getHeight()/2 , null); // get the images height and width values divided by two draw the image at the specified screen points return true; } @Override public boolean onTap(GeoPoint s, MapView mapView) { // Handle tapping on the overlay here return true; } }

• C# Uploading files to file server

  - by JustFoo

  Hello All, Currently I have an application that receives an uploaded file from my web application. I now need to transfer that file to a file server which happens to be located on the same network (however this might not always be the case). I was attempting to use the webclient class in C# .NET. string filePath = "C:\\test\\564.flv"; try { WebClient client = new WebClient(); NetworkCredential nc = new NetworkCredential(uName, password); Uri addy = new Uri("\\\\192.168.1.28\\Files\\test.flv"); client.Credentials = nc; byte[] arrReturn = client.UploadFile(addy, filePath); Console.WriteLine(arrReturn.ToString()); } catch (Exception ex) { Console.WriteLine(ex.Message); } The machine located at 192.168.1.28 is a file server and has a share c:\Files. As of right now I am receiving an error of Login failed bad user name or password, but I can open explorer and type in that path login successfully. I can also login using remote desktop, so I know the user account works. Any ideas on this error? Is it possible to transfer a file directly like that? With the webclient class or maybe some other class? Thanks

• Appending and prepending to XML files with Clojure

  - by Isaac Copper

  I have an XML file with format similar to: <root> <baby> <a>stuff</a> <b>stuff</b> <c>stuff</c> </baby> ... <baby> <a>stuff</a> <b>stuff</b> <c>stuff</c> </baby> </root> And a Clojure hash-map similar to: {:a "More stuff" :b "Some other stuff" :c "Yet more of that stuff"} And I'd like to prepend XML (¶) created from this hash-map after the <root> tag and before the first <baby> (¶) The XML to prepend would be like: <baby> <a>More stuff</a> <b>Some other stuff</b> <c>Yet more of that stuff</c> </baby> I'd also like to be able to delete the last one (or n...) <baby>...</baby>s from the file. I'm struggling with coming up with an idiomatic was to prepend and append this data. I can do raw string manipulations, or parse the XML using xml/parse and xml-seq and then roll through the nodes and (somehow?) replace the data there, but that seems messy. Any tips? Ideas? Hints? Pointers? They'd all be much appreciated. Thank you!

• How to get TinyMCE and Jquery validate to work together?

  - by chobo2

  Hi I am using jquery validate and the jquery version of tinymce. I found this piece of code that makes tinymce to validate itself every time something changes in it. Hi I am using the jquery validate with my jquery tinymce so I have this in my code // update validation status on change onchange_callback: function (editor) { tinyMCE.triggerSave(); $("#" + editor.id).valid(); }, This works however there is one problem. If a user copies something from word it brings all that junk styling with it what is usually over 50,000 characters. This is way over my amount of characters a user is allowed to type in. So my jquery validation method goes off telling me that they went over the limit. In the mean time though tinymce has cleaned up that mess and it could be possible now the user has not gone over the limit. Yet the message is still there. So is there a better function call I can put this in? Maybe tell tinymce to delay the valid when a paste is happening, or maybe a different callback? Anyone got any ideas?

• How do I exclude data from local table schema_migrations from being pushed to Heroku DB?

  - by Thierry Lam

  I was able to push my Ruby on Rails app with MySQL(local dev) to the Heroku server along with migrating my model with the command heroku rake db:migrate. I have also read the documentation on Database Import/Export. Is that doc referring to pushing actual data from my local dev DB to whichever Heroku's DB? Do I need to modify anything in the file database.yml to make it happen? I ran the following command: heroku db:push and I am getting the error: Sending data 2 tables, 3 records !!! Caught Server Exception | ETA: --:--:-- Taps Server Error: PGError ERROR: duplicate key value violates unique constraint "unique_schema_migrations" I have 2 tables, one I create for my app and the other schema_migrations. The total number of entries among the 2 tables is 3. I'm also printing the number of entries I have in the table I have created and it's showing 0. Any ideas what I might be missing or what I am doing wrong? EDIT: I figured out the above, Heroku's DB already have schema_migrations the moment I ran migrate. New question: Does anyone know how I can exclude data from a specific table from being pushed to Heroku DB. The table to exclude in this case will be schema_migrations. Not so good solution: I googled around and someone else was having the same issue. He suggested naming the schema_migrations table to zschema_migrations. In this way data from the other tables will be pushed properly until it fails on the last table. It's a pretty bad solution but will do for the time being. A better solution will be to use an existing Rails command which can reset a specific table from a database. I don't think Rake can do that.

• Something like jQuery's .resizable but without the div's inside

  - by Brendon Muir

  Hi everyone, this is just a quick probe to see if this is technically possible. I'm wanting to enable the resizing of an image in the browser (also within a contentEditable area). Firefox and IE already allow this to be done with their inbuilt handles and it works fine. I'm wanting to implement something for Safari however because it doesn't support this natively. I've had a go with jQuery's resizable method and it does a very good job, however it relies on inserting a bunch of div's along with the image and wrapping that in a big div. This would normally be fine if we weren't concerned with the code generated in the contentEditable area, but we are because it's going to be saved back to the server. I could strip this extra stuff out on save, but I was thinking, is it technically possible to create a resizing script for images that doesn't rely on adding extra div's? Even if we decide to go without handles for now, and just concentrate on detecting when a user is close to the edge of the image, change the mouse cursor to a resizing one, and detect clicks and drags in the 5px's around the edge of the image, is this possible? If it's possible, I'm assuming (hoping) that perhaps it's already been done, but my searching hasn't turned up anything so far. Keen to hear any ideas :)

• How do you efficiently bulk index lookups?

  - by Liron Shapira

  I have these entity kinds: Molecule Atom MoleculeAtom Given a list(molecule_ids) whose lengths is in the hundreds, I need to get a dict of the form {molecule_id: list(atom_ids)}. Likewise, given a list(atom_ids) whose length is in the hunreds, I need to get a dict of the form {atom_id: list(molecule_ids)}. Both of these bulk lookups need to happen really fast. Right now I'm doing something like: atom_ids_by_molecule_id = {} for molecule_id in molecule_ids: moleculeatoms = MoleculeAtom.all().filter('molecule =', db.Key.from_path('molecule', molecule_id)).fetch(1000) atom_ids_by_molecule_id[molecule_id] = [ MoleculeAtom.atom.get_value_for_datastore(ma).id() for ma in moleculeatoms ] Like I said, len(molecule_ids) is in the hundreds. I need to do this kind of bulk index lookup on almost every single request, and I need it to be FAST, and right now it's too slow. Ideas: Will using a Molecule.atoms ListProperty do what I need? Consider that I am storing additional data on the MoleculeAtom node, and remember it's equally important for me to do the lookup in the molecule-atom and atom-molecule directions. Caching? I tried memcaching lists of atom IDs keyed by molecule ID, but I have tons of atoms and molecules, and the cache can't fit it. How about denormalizing the data by creating a new entity kind whose key name is a molecule ID and whose value is a list of atom IDs? The idea is, calling db.get on 500 keys is probably faster than looping through 500 fetches with filters, right?

• When is onBind or onCreate called in an android service browser plugin?

  - by anselm

  I have adapted the example plugin of the android source and the browser recognises the plugin without any problem. Here is an extract of AndroidManifest.xml: <application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true"> <service android:name="com.domain.plugin.PluginService"> <intent-filter> <action android:name="android.webkit.PLUGIN" /> </intent-filter> </service> </application> <uses-sdk android:minSdkVersion="7" /> <uses-permission android:name="android.webkit.permission.PLUGIN"></uses-permission> The actual Service class looks like so: public class PluginService extends Service { @Override public IBinder onBind(Intent arg0) { Log.d("PluginService", "onBind"); return null; } @Override public void onCreate() { Log.d("PluginService", "onCreate"); // TODO Auto-generated method stub super.onCreate(); AssetInstaller.getInstance(this).installAssets("/data/data/com.domain.plugin"); } } The AssetInstaller code is supposed to extract some files required by the actual plugin into the /data/data/com.domain.plugin directory, however wether onBind nor onCreate are called. But I get lot's of debug trace of the actual libnpplugin.so file I'm using. So the puzzle is when and under what circumstance is the Service bound or created in case of a browser plugin. As things look the service seems to be a dummy service. Having said that, is there another intent that can be executed at installation time probably? The only solution I see right now is installing the needed files from the native plugin code instead. Any ideas? I know this is quite a tricky question ;)

• Google Maps, marker info window won't show up ?

  - by user296516

  Hi guys, I have written this code that loops through an array of lat/long coordinates and places a marker at each of the coordinate. Everything forks fine, exempt the info window won't appear once the marker is clicked. var ExpTowerIcon = new GIcon(); ExpTowerIcon.image = "tower.png"; ExpTowerIcon.iconSize = new GSize(75, 75); ExpTowerIcon.iconAnchor = new GPoint(37, 65); ExpTowerIcon.infoWindowAnchor = new GPoint(37, 20); var marker=new Array(); for ( i=0 ; i < lat.length ; i++ ) { var MarkerPoint = new GLatLng(lat[i],long[i]); marker[i] = new GMarker(MarkerPoint,{icon:ExpTowerIcon}) map.addOverlay( marker[i] ); GEvent.addListener( marker[i] , 'click', function() { marker[i].openInfoWindowHtml('Hello!') ; }); var polyline = new GPolyline([ new GLatLng(lat[i],long[i]) , new GLatLng(lat[i+1],long[i+1]) ], "#ff0000", 5); map.addOverlay(polyline); } Any ideas? Thanks!

• How to get list of declared functions with their data from php file?

  - by ermac2014

  I need to get list of functions with their contents (not only the function name) from php file. I tried to use regex but it has lots of limitations. it doesn't parse all types of functions. for example it fails if the function has if and for loop statements. in details: I have around 100 include files. each file has number of declared functions. some files has functions duplicated in other files. so what I want is to get list of all functions from specific file then put this list inside an array then I will be using array unique in order to remove the duplicates. I read about tokenizer but I really have no idea how to make it grab the declared function with its data. all I have is this: function get_defined_functions_in_file($file) { $source = file_get_contents($file); $tokens = token_get_all($source); $functions = array(); $nextStringIsFunc = false; $inClass = false; $bracesCount = 0; foreach($tokens as $token) { switch($token[0]) { case T_CLASS: $inClass = true; break; case T_FUNCTION: if(!$inClass) $nextStringIsFunc = true; break; case T_STRING: if($nextStringIsFunc) { $nextStringIsFunc = false; $functions[] = $token[1]; } break; // Anonymous functions case '(': case ';': $nextStringIsFunc = false; break; // Exclude Classes case '{': if($inClass) $bracesCount++; break; case '}': if($inClass) { $bracesCount--; if($bracesCount === 0) $inClass = false; } break; } } return $functions; } unfortunately, this function lists only the function names.. what I need is to list the whole declared function with its structure.. so any ideas? thanks in advance..

• Javascript algorithm to find elements in array that are not in another array

  - by Tauren

  I'm looking for a good algorithm to get all the elements in one array that are not elements in another array. So given these arrays: var x = ["a","b","c","t"]; var ?????????y = [???????"d","a","t","e","g"]; I want to end up with this array: var z = ["d","e","g"]; I'm using jquery, so I can take advantage of $.each() and $.inArray(). Here's the solution I've come up with, but it seems like there should be a better way. // goal is to get rid of values in y if they exist in x var x = ["a","b","c","t"]; var y = ["d","a","t","e","g"]; var z = []; $.each(y, function(idx, value){ if ($.inArray(value,x) == -1) { z.push(value); } }); ?alert(z); // should be ["d","e","g"] Here is the code in action. Any ideas?
