  • facebook connect button not producing pop-up

    - by bigmac
    This is a really simple question, but I can't seem to find the answer. I am just getting started with Facebook Connect. I would like to use it only for user authentication, so there is no need for my users to create another account. I used a very basic example from wiki.developers.facebook.com : <html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml"> <head></head> <body> <fb:login-button></fb:login-button> <script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php/en_US" type="text/javascript"></script> <script type="text/javascript"> FB.init("***api-key***", "xd_receiver.htm"); </script> </body> </html> Very straight forward. It seems to work fine. However, if I am currently already logged in to Facebook, the pop-up window doesn't come up when I click the login button. Why is that?

  • Poll multiple desktops/servers on a network remotely to determine the IP Type: Static or DHCP

    - by Charles Laird
    Had a gentleman answer 90% of my original question, which is to say I now have the ability to poll a device that I am running the below script on. The end goal is to obtain IP type: Static or DHCP on all desktop/servers on a network I support. I have the list of servers that I will input in a batch file, just looking for the code to actually poll the other devices on the network from one location. Output to be viewed: Device name: IP Address: MAC Address: Type: Marvell Yukon 88E8001/8003/8010 PCI Gigabit Ethernet Controller NULL 00:00:F3:44:C6:00 DHCP Generic Marvell Yukon 88E8056 based Ethernet Controller 192.168.1.102 00:00:F3:44:D0:00 DHCP ManagementClass objMC = new ManagementClass("Win32_NetworkAdapterConfiguration"); ManagementObjectCollection objMOC = objMC.GetInstances(); txtLaunch.Text = ("Name\tIP Address\tMAC Address\tType" +"\r\n"); foreach (ManagementObject objMO in objMOC) { StringBuilder builder = new StringBuilder(); object o = objMO.GetPropertyValue("IPAddress"); object m = objMO.GetPropertyValue("MACAddress"); if (o != null || m != null) { builder.Append(objMO["Description"].ToString()); builder.Append("\t"); if (o != null) builder.Append(((string[])(objMO["IPAddress"]))[0].ToString()); else builder.Append("NULL"); builder.Append("\t"); builder.Append(m.ToString()); builder.Append("\t"); builder.Append(Convert.ToBoolean(objMO["DHCPEnabled"]) ? "DHCP" : "Static"); builder.Append("\r\n"); } txtLaunch.Text = txtLaunch.Text + (builder.ToString()); I'm open to recommendations here.

  • Code Golf: Quickly Build List of Keywords from Text, Including # of Instances

    - by Jonathan Sampson
    I've already worked out this solution for myself with PHP, but I'm curious how it could be done differently - better even. The two languages I'm primarily interested in are PHP and Javascript, but I'd be interested in seeing how quickly this could be done in any other major language today as well (mostly C#, Java, etc). Return only words with an occurrence greater than X Return only words with a length greater than Y Ignore common terms like "and, is, the, etc" Feel free to strip punctuation prior to processing (ie. "John's" becomes "John") Return results in a collection/array Extra Credit Keep Quoted Statements together, (ie. "They were 'too good to be true' apparently")Where 'too good to be true' would be the actual statement Extra-Extra Credit Can your script determine words that should be kept together based upon their frequency of being found together? This being done without knowing the words beforehand. Example: "The fruit fly is a great thing when it comes to medical research. Much study has been done on the fruit fly in the past, and has lead to many breakthroughs. In the future, the fruit fly will continue to be studied, but our methods may change." Clearly the word here is "fruit fly," which is easy for us to find. Can your search'n'scrape script determine this too? Source text: http://sampsonresume.com/labs/c.txt Answer Format It would be great to see the results of your code, output, in addition to how long the operation lasted.

  • Interface Casting vs. Class Casting

    - by Legatou
    I've been led to believe that casting can, in certain circumstances, become a measurable hindrance on performance. This may be moreso the case when we start dealing with incoherent webs of nasty exception throwing\catching. Given that I wish to create more correct heuristics when it comes to programming, I've been prompted to ask this question to the .NET gurus out there: Is interface casting faster than class casting? To give a code example, let's say this exists: public interface IEntity { IParent DaddyMommy { get; } } public interface IParent : IEntity { } public class Parent : Entity, IParent { } public class Entity : IEntity { public IParent DaddyMommy { get; protected set; } public IParent AdamEve_Interfaces { get { IEntity e = this; while (this.DaddyMommy != null) e = e.DaddyMommy as IEntity; return e as IParent; } } public Parent AdamEve_Classes { get { Entity e = this; while (this.DaddyMommy != null) e = e.DaddyMommy as Entity; return e as Parent; } } } So, is AdamEve_Interfaces faster than AdamEve_Classes? If so, by how much? And, if you know the answer, why?

  • Need to kill a session?

    - by rob - not a robber
    Really quick here... I think I have the answer, but just looking for some validation. I have a site with two "points of entry." One is for a standard user and one is for an admin account. In the real world, an admin could have a standard user account and try to login as an admin while already being under the standard user session. I have two separate front ends to facilitate login. The normal user one is frilly and has ads and the like, the admin one is strictly business, so any suggestion to have the two user types login through the same "door" is not on the table. Would you advise on the admin login page to destroy any active sessions? Once the admin is in, they'll only be tooling around in their admin area and not on the main site. Has anyone run into probs using this method and having an admin-type user try to log back in in a new window as a "user" to view changes from a logged in user's prespective? Thanks in advance. So many cans of worms :)

  • Ruby on Rails / Yellow Maps For Ruby Plugin woes...

    - by Zach
    Okay I've read through the plugin comments and the docs as well and I have yet to come up with an answer as to how to do this. Here's my problem I want to use the :info_window_tabs and the :icon option, but I don't know what format to pass my information in. According to the documentation the following code should be correct. Here's my code: @mapper.overlay_init(GMarker.new([map.lat, map.lng], :title => map.name, :info_window_tabs => [ {:tab => "HTML", :content => @marker_html}, {:tab => "Attachments", :content => "stuff"}], :icon => { :image => "../images/icon.png" })) The readme and documentation can be viewed here. And the relevant ruby file that I am trying to interact with, including the author's comments, can be viewed here. I have tried the #rubyonrails channel in IRC as well as emailing the author directly and reporting an issue at GitHub. It really is just a question of syntax. Thanks!

  • Java Playing Cards Game Framework

    - by isme
    My friends and I at uni love playing Shithead into the wee hours. But soon we graduate and will leave town, so probably won't get together for a game for a while. I want to develop a Java app we can use to play Shithead and our other favorites over a network. An app like this already exists, but is ugly, buggy and does not support our house rules. The source is available, but is such a mess that I would really rather start from scratch than try to refactor it! Building my game using some standard playing card api or framework, if such a thing exists, would be better than starting from scratch. The answer to a similar SO question was to use the JPC-API, which allegedly provides basic playing card services and rendering. But this Sourceforge project currently makes available no files or source code! Is there an alternative, or somewhere else to find this framework? Soon I will need help with the following as well: Lobby services (finding other players) Gaming network protocol (to communicate moves between players) Gaming theory (to write the computer opponent) Winning condition detection Game UI development

  • Heuristic to identify if a series of 4 bytes chunks of data are integers or floats

    - by flint
    What's the best heuristic I can use to identify whether a chunk of X 4-bytes are integers or floats? A human can do this easily, but I wanted to do it programmatically. I realize that since every combination of bits will result in a valid integer and (almost?) all of them will also result in a valid float, there is no way to know for sure. But I still would like to identify the most likely candidate (which will virtually always be correct; or at least, a human can do it). For example, let's take a series of 4-bytes raw data and print them as integers first and then as floats: 1 1.4013e-45 10 1.4013e-44 44 6.16571e-44 5000 7.00649e-42 1024 1.43493e-42 0 0 0 0 -5 -nan 11 1.54143e-44 Obviously they will be integers. Now, another example: 1065353216 1 1084227584 5 1085276160 5.5 1068149391 1.33333 1083179008 4.5 1120403456 100 0 0 -1110651699 -0.1 1195593728 50000 These will obviously be floats. PS: I'm using C++ but you can answer in any language, pseudo code or just in english.

  • Python metaclass for enforcing immutability of custom types

    - by Mark Lehmacher
    Having searched for a way to enforce immutability of custom types and not having found a satisfactory answer I came up with my own shot at a solution in form of a metaclass: class ImmutableTypeException( Exception ): pass class Immutable( type ): ''' Enforce some aspects of the immutability contract for new-style classes: - attributes must not be created, modified or deleted after object construction - immutable types must implement __eq__ and __hash__ ''' def __new__( meta, classname, bases, classDict ): instance = type.__new__( meta, classname, bases, classDict ) # Make sure __eq__ and __hash__ have been implemented by the immutable type. # In the case of __hash__ also make sure the object default implementation has been overridden. # TODO: the check for eq and hash functions could probably be done more directly and thus more efficiently # (hasattr does not seem to traverse the type hierarchy) if not '__eq__' in dir( instance ): raise ImmutableTypeException( 'Immutable types must implement __eq__.' ) if not '__hash__' in dir( instance ): raise ImmutableTypeException( 'Immutable types must implement __hash__.' ) if _methodFromObjectType( instance.__hash__ ): raise ImmutableTypeException( 'Immutable types must override object.__hash__.' ) instance.__setattr__ = _setattr instance.__delattr__ = _delattr return instance def __call__( self, *args, **kwargs ): obj = type.__call__( self, *args, **kwargs ) obj.__immutable__ = True return obj def _setattr( self, attr, value ): if '__immutable__' in self.__dict__ and self.__immutable__: raise AttributeError( "'%s' must not be modified because '%s' is immutable" % ( attr, self ) ) object.__setattr__( self, attr, value ) def _delattr( self, attr ): raise AttributeError( "'%s' must not be deleted because '%s' is immutable" % ( attr, self ) ) def _methodFromObjectType( method ): ''' Return True if the given method has been defined by object, False otherwise. ''' try: # TODO: Are we exploiting an implementation detail here? Find better solution! return isinstance( method.__objclass__, object ) except: return False However, while the general approach seems to be working rather well there are still some iffy implementation details (also see TODO comments in code): How do I check if a particular method has been implemented anywhere in the type hierarchy? How do I check which type is the origin of a method declaration (i.e. as part of which type a method has been defined)?

  • Why calling Process.killProcess(Process.myPid()) is a bad idea?

    - by Tal Kanel
    I've read some posts saying using this method is "not good", shouldn't been use, it's not the right way to "close" the application and it's not how android works... I understand and accept the fact that Android OS knows better then me when it's the right time to terminate the process, but I didn't heard yet a good explanation why it's wrong using the killProcess() method?. after all - it's part of the android API... what I do know is that calling this method while other threads doing in potential an important work (operations on files, writing to DB, HTTP requests, running services..) can be terminated in the middle, and it's clearly not good. also I know I can benefit from the fact that "re-open" the application will be faster, cause the system maybe still "holds" in memory state from last time been used, and killProcess() prevents that. beside this reason, in assumption I don't have such operations, and I don't care my application will load from scratch each run, there are other reasons why not using the killProcess() method? I know about finish() method to close an Activity, so don't write me about that please.. finish() is only for Activity. not to all application, and I think I know exactly why and when to use it... and another thing - I'm developing also games with the Unity3D framework, and exporting the project to android. when I decompiled the generated apk, I was very suprised to find out that the java source code created from unity - implementing Unity's - Application.quit() method, with Process.killProcess(Process.myPid()). Application.quit() is suppose to be the right way to close game according to Unity3d guides (is it really?? maybe I'm wrong, and missed something), so how it happens that the Unity's framework developers which doing a very good work as it seems implemented this in native android to killProcess()? anyway - I wish to have a "list of reasons" why not using the killProcess() method, so please write down your answer - if you have something interesting to say about that. TIA

  • Reference a Map by name within Velocity Template

    - by Wiretap
    Pretty sure there is an easy answer to this, but just can't find the right VTL syntax. In my context I'm passing a Map which contains other Maps. I'd like to reference these inner maps by name and assign them within my template. The inner maps are constructed by different parts of the app, and then added to the context by way of example public static void main( String[] args ) throws Exception { VelocityEngine ve = new VelocityEngine(); ve.init(); Template t = ve.getTemplate( "test.vm" ); VelocityContext context = new VelocityContext(); Map<String,Map<String,String>> messageData = new HashMap<String, Map<String,String>>(); Map<String,String> data_map = new HashMap<String,String>(); data_map.put("data_1","1234"); data_map.put("a_date", "31-Dec-2009"); messageData.put("inner_map", data_map); context.put("msgData", messageData); StringWriter writer = new StringWriter(); t.merge( context, writer ); System.out.println( writer.toString() ); } Template - test.vm #set ($in_map = $msgData.get($inner_map) ) data: $in_map.data_1 $in_map.a_date

  • How to make NAnt send an email using a real account

    - by Turro
    First of all, I have already seen this post: nant mail issues but the only answer is not satisfactory (i.e.: doesn't work for me). I am using NAnt to get latest version of source, upgrade version of the libraries and application, build the application, build the setups... all the usual things, I bet. I would like NAnt to send an email to some people confirming the conclusion of the build process; I've already checked the official (pretty ugly, IMHO) documentation for the task, but the example, once copied and customized, doesn't work. This are the NAnt target and task I'm using: <target name="sendMail" > <mail from="[email protected]" tolist="[email protected];[email protected]" subject="Subject of email" mailhost="smtp.gmail.com" message="Your new release is ready!"> </mail> </target> The error message I get is: 530 5.7.0 Must issue a STARTTLS command first. It looks like that the task was designed for use by an account whose provider doesn't need authentication; but what can I do if I must use an external smtp server which requires authentication (telling my boss I need an smtp server in house is not an option)? Can anybody help/teach me? Thanks in advance...

  • C++ stack in Objective-C++

    - by helixed
    I'd like to use a C++ stack type in Objective-C, but I'm running into some issues. Here's a sample of what I would like to do: #import <stack> #import <UIKit/UIKit.h> @interface A : NSObject { stack<SEL> selectorStack; } @end Unfortunately, this doesn't compile. After messing around with the code for a while and trying different things, I can't seem to find a way to accomplish this. Can somebody tell me the best way to use a C++ stack within an Objective-C object or if it's even possible? Thanks. UPDATE: Well, KennyTM's answer worked on my example file, but for some reason when I tried to rename the class it quit working. Here's the code I have right now: #import <stack> #import <UIKit/UIKit.h> @interface MenuLayer : NSObject { std::stack<SEL> selectorStack; } @end The compiler spits out the following errors: stack: No such file or directory expected specifier-qualifier-list before 'std'

  • window.onload seems to trigger before the DOM is loaded (JavaScript)

    - by Dr. Monkey
    I am having trouble with the window.onload and document.onload events. Everything I read tells me these will not trigger until the DOM is fully loaded with all its resources, it seems like this isn't happening for me: I tried the following simple page in Chrome 4.1.249.1036 (41514) and IE 8.0.7600.16385 with the same result: both displayed the message "It failed!", indicating that myParagraph is not loaded (and so the DOM seems incomplete). <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> <head> <script type="text/javascript"> window.onload = doThis(); // document.onload gives the same result function doThis() { if (document.getElementById("myParagraph")) { alert("It worked!"); } else { alert("It failed!"); } } </script> </head> <body> <p id="myParagraph">Nothing is here.</p> </body> </html> I am using more complex scripts than this, in an external .js file, but this illustrates the problem. I can get it working by having window.onload set a timer for half a second to run doThis(), but this seems like an inelegant solution, and doesn't answer the question of why window.onload doesn't seem to do what everyone says it does. Another solution would be to set a timer that will check if the DOM is loaded, and if not it will just call itself half a second later (so it will keep checking until the DOM is loaded), but this seems overly complex to me. Is there a more appropriate event to use?

  • How do I create a multi-level TreeView using F#?

    - by TwentyMiles
    I would like to display a directory structure using Gtk# widgets through F#, but I'm having a hard time figuring out how to translate TreeViews into F#. Say I had a directory structure that looks like this: Directory1 SubDirectory1 SubDirectory2 SubSubDirectory1 SubDirectory3 Directory2 How would I show this tree structure with Gtk# widgets using F#? EDIT: gradbot's was the answer I was hoping for with a couple of exceptions. If you use ListStore, you loose the ability to expand levels, if you instead use : let musicListStore = new Gtk.TreeStore([|typeof<String>; typeof<String>|]) you get a layout with expandable levels. Doing this, however, breaks the calls to AppendValues so you have to add some clues for the compiler to figure out which overloaded method to use: musicListStore.AppendValues (iter, [|"Fannypack" ; "Nu Nu (Yeah Yeah) (double j and haze radio edit)"|]) Note that the columns are explicitly passed as an array. Finally, you can nest levels even further by using the ListIter returned by Append Values let iter = musicListStore.AppendValues ("Dance") let subiter = musicListStore.AppendValues (iter, [|"Fannypack" ; "Nu Nu (Yeah Yeah) (double j and haze radio edit)"|]) musicListStore.AppendValues (subiter, [|"Some Dude"; "Some Song"|]) |> ignore

  • Database warehoue design: fact tables and dimension tables

    - by morpheous
    I am building a poor man's data warehouse using a RDBMS. I have identified the key 'attributes' to be recorded as: sex (true/false) demographic classification (A, B, C etc) place of birth date of birth weight (recorded daily): The fact that is being recorded My requirements are to be able to run 'OLAP' queries that allow me to: 'slice and dice' 'drill up/down' the data and generally, be able to view the data from different perspectives After reading up on this topic area, the general consensus seems to be that this is best implemented using dimension tables rather than normalized tables. Assuming that this assertion is true (i.e. the solution is best implemented using fact and dimension tables), I would like to see some help in the design of these tables. 'Natural' (or obvious) dimensions are: Date dimension Geographical location Which have hierarchical attributes. However, I am struggling with how to model the following fields: sex (true/false) demographic classification (A, B, C etc) The reason I am struggling with these fields is that: They have no obvious hierarchical attributes which will aid aggregation (AFAIA) - which suggest they should be in a fact table They are mostly static or very rarely change - which suggests they should be in a dimension table. Maybe the heuristic I am using above is too crude? I will give some examples on the type of analysis I would like to carryout on the data warehouse - hopefully that will clarify things further. I would like to aggregate and analyze the data by sex and demographic classification - e.g. answer questions like: How does male and female weights compare across different demographic classifications? Which demographic classification (male AND female), show the most increase in weight this quarter. etc. Can anyone clarify whether sex and demographic classification are part of the fact table, or whether they are (as I suspect) dimension tables.? Also assuming they are dimension tables, could someone elaborate on the table structures (i.e. the fields)? The 'obvious' schema: CREATE TABLE sex_type (is_male int); CREATE TABLE demographic_category (id int, name varchar(4)); may not be the correct one.

  • How to do Basic Authentication using FireWatir on Ubuntu Linux?

    - by lotharsmash
    Hi, I'm trying to use FireWatir (1.6.5) to access a site using Basic Authentication and I've been unable to find a solution that works on Firefox in Linux. Does FireWatir 1.6.5 support Basic Authentication on Linux? I've been searching the web for 2 days and can't get a straight answer anywhere as to how to do this. The only thread I found that seemed helpful was this one ( http://groups.google.com/group/watir-general/browse_thread/thread/d8ab9a177d282ce4/fc1bf2319fb387d8?lnk=gst&q=basic+authentication#fc1bf2319fb387d8). Aedorn Varanis says " Angrez's fork had the solution so I'm using that now. Thanks Angrez, works perfectly!", but he doesn't mention what he did to get things working. Initially I tried to bypass the authentication dialog box by using: browser.goto('http://admin:[email protected]') However, this generates a "Confirm" dialog which says: "You are about to log in to the site "172.20.1.1" with the username "admin"." [Cancel, OK] This dialog blocks, and the goto call won't return until I click "OK". Then I tried adding: browser.startClicker("ok") browser.goto('http://admin:[email protected]') But this ALSO generates the same "Confirm" dialog. I tested out the startClicker functionality using the unit test /var/ lib/gems/1.8/gems/firewatir-1.6.5/unittests/html/JavascriptClick.html and it worked fine, which makes me think that using the startClicker method is NOT the correct way to take care of the Confirm dialog. Anybody else found a way to get Basic Auth to work, or how to click the OK on the confirm dialog? I'm at my wits end...

  • Mercurial: a few questions all related to .hgignore

    - by WizardOfOdds
    I've been working for a long time with a .hgignore file that was fine and recently added one new type of files to ignore. When running "hg status", I noticed this: M .hgignore So Mercurial considers the .hgignore to be a file that needs to be tracked (if it's a the root of the project). Now I've read various docs but my points weren't specifically adressed so here are some very detailed questions which hopefully can help me figure this out (it would be great is someone answering could quote and address these three points [even with a simply yes/no answer for each question]): Should .hgignore be at the root of the project? (I guess it should, seen that a developer can potentially be working on several projects which would all have different .hgignore requirements) Can .hgignore be ignored be Mercurial? If it can be ignored, should .hgignore be ignored by Mercurial (which is different than the previous question) In the case where .hgignore should not be ignored, can't some really bad thing happens if you suddenly rollback way earlier, when a really old and incomplete .hgignore was used? I think I saw weird things happening with certain per-user IDE project files (I'm not saying all IDEs project files are per-user only, but some definitely are) that were supposed to be ignored, but then the user rolls back to an old version, where an old .hgignore gets used, and then suddenly files supposed to be ignored are committed because the old .hgignore didn't exclude these.

  • adding stock data to amibroker using c#

    - by femi
    hello, I have had a hard time getting and answer to this and i would really , really appreciate some help on this. i have been on this for over 2 weeks without headway. i want to use c# to add a line of stock data to amibroker but i just cant find a CLEAR response on how to instantiate it in C#. In VB , I would do it something like; Dim AmiBroker = CreateObject("Broker.Application") sSymbol = ArrayRow(0).ToUpper Stock = AmiBroker.Stocks.Add(sSymbol) iDate = ArrayRow(1).ToLower quote = Stock.Quotations.Add(iDate) quote.Open = CSng(ArrayRow(2)) quote.High = CSng(ArrayRow(3)) quote.Low = CSng(ArrayRow(4)) quote.Close = CSng(ArrayRow(5)) quote.Volume = CLng(ArrayRow(6)) The problem is that CreateObject will not work in C# in this instance. I found the code below somewhere online but i cant seem to understand how to achieve the above. Type objClassType; objClassType = Type.GetTypeFromProgID("Broker.Application"); // Instantiate AmiBroker objApp = Activator.CreateInstance(objClassType); objStocks = objApp.GetType().InvokeMember("Stocks", BindingFlags.GetProperty,null, objApp, null); Can anyone help me here?

  • Defining jUnit Test cases Correctly

    - by Epitaph
    I am new to Unit Testing and therefore wanted to do some practical exercise to get familiar with the jUnit framework. I created a program that implements a String multiplier public String multiply(String number1, String number2) In order to test the multiplier method, I created a test suite consisting of the following test cases (with all the needed integer parsing, etc) @Test public class MultiplierTest { Multiplier multiplier = new Multiplier(); // Test for 2 positive integers assertEquals("Result", 5, multiplier.multiply("5", "1")); // Test for 1 positive integer and 0 assertEquals("Result", 0, multiplier.multiply("5", "0")); // Test for 1 positive and 1 negative integer assertEquals("Result", -1, multiplier.multiply("-1", "1")); // Test for 2 negative integers assertEquals("Result", 10, multiplier.multiply("-5", "-2")); // Test for 1 positive integer and 1 non number assertEquals("Result", , multiplier.multiply("x", "1")); // Test for 1 positive integer and 1 empty field assertEquals("Result", , multiplier.multiply("5", "")); // Test for 2 empty fields assertEquals("Result", , multiplier.multiply("", "")); In a similar fashion, I can create test cases involving boundary cases (considering numbers are int values) or even imaginary values. 1) But, what should be the expected value for the last 3 test cases above? (a special number indicating error?) 2) What additional test cases did I miss? 3) Is assertEquals() method enough for testing the multiplier method or do I need other methods like assertTrue(), assertFalse(), assertSame() etc 4) Is this the RIGHT way to go about developing test cases? How am I "exactly" benefiting from this exercise? 5)What should be the ideal way to test the multiplier method? I am pretty clueless here. If anyone can help answer these queries I'd greatly appreciate it. Thank you.

  • setAttribute, onClick and cross browser compatability...

    - by Nicholas Kreidberg
    I have read a number of posts about this but none with any solid answer. Here is my code: // button creation onew = document.createElement('input'); onew.setAttribute("type", "button"); onew.setAttribute("value", "hosts"); onew.onclick = function(){fnDisplay_Computers("'" + alines[i] + "'"); }; // ie onew.setAttribute("onclick", "fnDisplay_Computers('" + alines[i] + "')"); // mozilla odiv.appendChild(onew); Now, the setAttribute() method (with the mozilla comment) works fine in mozilla but only if it comes AFTER the line above it. So in other words it seems to just default to whichever gets set last. The .onclick method (with the ie comment) does not work in either case, am I using it incorrectly? Either way I can't find a way to make this work at all in IE, let alone in both. I did change the function call when using the .onclick method and it worked fine using just a simple call to an alert function which is why I believe my syntax is incorrect. Long story short, I can't get the onclick parameter to work consistently between IE/Mozilla. -- Nicholas

  • Removing a fields from a dynamic ModelForm

    - by Jérôme Pigeot
    In a ModelForm, i have to test user permissions to let them filling the right fields : It is defined like this: class TitleForm(ModelForm): def __init__(self, user, *args, **kwargs): super(TitleForm,self).__init__(*args, **kwargs) choices = [] # company if user.has_perm("myapp.perm_company"): self.fields['company'] = forms.ModelChoiceField(widget=forms.HiddenInput(), queryset=Company.objects.all(), required=False) choices.append('Company') # association if user.has_perm("myapp.perm_association") self.fields['association'] = forms.ModelChoiceField(widget=forms.HiddenInput(), queryset=Association.objects.all(), required=False) choices.append('Association') # choices self.fields['type_resource'] = forms.ChoiceField(choices = choices) class Meta: Model = Title This ModelForm does the work : i hide each field on the template and make them appearing thanks to javascript... The problem is this ModelForm is that each field defined in the model will be displayed on the template. I would like to remove them from the form if they are not needed: exemple : if the user has no right on the model Company, it won't be used it in the rendered form in the template. The problem of that is you have to put the list of fields in the Meta class of the form with fields or exclude attribute, but i don't know how to manage them dynamically. Any Idea?? Thanks by advance for any answer.

  • How to write PIL image filter for plain pgm format?

    - by Juha
    How can I write a filter for python imaging library for pgm plain ascii format (P2). Problem here is that basic PIL filter assumes constant number of bytes per pixel. My goal is to open feep.pgm with Image.open(). See http://netpbm.sourceforge.net/doc/pgm.html or below. Alternative solution is that I find other well documented ascii grayscale format that is supported by PIL and all major graphics programs. Any suggestions? br, Juha feep.pgm: P2 # feep.pgm 24 7 15 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 3 3 3 3 0 0 7 7 7 7 0 0 11 11 11 11 0 0 15 15 15 15 0 0 3 0 0 0 0 0 7 0 0 0 0 0 11 0 0 0 0 0 15 0 0 15 0 0 3 3 3 0 0 0 7 7 7 0 0 0 11 11 11 0 0 0 15 15 15 15 0 0 3 0 0 0 0 0 7 0 0 0 0 0 11 0 0 0 0 0 15 0 0 0 0 0 3 0 0 0 0 0 7 7 7 7 0 0 11 11 11 11 0 0 15 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 edit: Thanks for the answer, I works... but I need a solution that uses Image.open(). Most of python programs out there use PIL for graphics manipulation (google: python image open). Thus, I need to be able to register a filter to PIL. Then, I can use any software that uses PIL. I now think mostly scipy, pylab, etc. dependent programs.

  • How to create reactive tasks for programming competitions?

    - by directx
    A reactive task is sometimes seen in the IOI programming competition. Unlike batch tasks, reactive solutions take input from another program as well as outputting it. The program typically 'query' the judge program a certain number of times, then output a final answer. An example The client program accepts lines one by one, and simply echoes it back. When it encountered a line with "done", it exists immediately. The client program in Java looks like this: import java.util.*; class Main{ public static void main (String[] args){ Scanner in = new Scanner(System.in); String s; while (!(s=in.nextLine()).equals("done")) System.out.println(s); } } The judge program gives the input and processes output from the client program. In this example, it feeds it a predefined input and checks if the client program has echoed it back correctly. A session might go like this: Judge Client ------------------ Hello Hello World World done I'm having trouble writing the judge program and having it judge the client program. I'd appreciate if someone could write a judge program for my example.

  • How to launch multiple Internet Explorer windows/tabs from batch file?

    - by TheZenker
    I would like a batch file to launch two separate programs then have the command line window close. Actually, to clarify, I am launching Internet Explorer with two different URLs. So far I have something like this: start "~\iexplore.exe" "url1" start "~\iexplore.exe" "url2" What I get is one instance of Internet Explorer with only the second URL loaded. Seems the second is replacing the second. I seem to remember a syntax where I would load a new command line window and pass the command to execute on load, but can't find the reference. As a second part of the question: what is a good reference URL to keep for the times you need to write a quick batch file? Edit: I have marked an answer, because it does work. I now have two windows open, one for each URL. (thanks!) The funny thing is that without the /d approach using my original syntax I get different results based on whether I have a pre-existing Internet Explorer instance open. If I do I get two new tabs added for my two URLs (sweet!) If not I get only one final tab for the second URL I passed in.
