  • How someone using my Facebook website app can post to their pages timeline

    - by user1334414
    I have a website where businesses create content through a PHP backend system. Each time they create a new piece of content, I want it to publish to their Facebook pages timeline (not the users timeline). I have created the authenticate code: <div id="fb-root"></div> <script> window.fbAsyncInit = function() { FB.init({ appId : 'XXXXXXXXXX', status : true, cookie : true, xfbml : true, oauth : true, }); }; (function(d){ var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;} js = d.createElement('script'); js.id = id; js.async = true; js.src = "//connect.facebook.net/en_US/all.js"; d.getElementsByTagName('head')[0].appendChild(js); }(document)); </script> <div class="fb-login-button" scope="manage_pages"> Login with Facebook </div> With manage_pages as a scope. I need to know how they can select which page they want the post to go to (if they have more than 1 page), and also how to automatically post to that pages wall when they submit the content (which is done via a PHP form). Thanks

  • need to change TextBox.Text inside TextChanged, something forces form close

    - by Istrebitel
    I am making a TextBox behave like if it could store a null value. In order to do that, i have a variable NullMode that indicates wether the value is stored is Null, and in TextChanged i set that to false, and on specific user action i set it to true and Text to a value that indicates that there is null inside the textbox. Then, based on NullMode, textbox is drawn differently. Now, i have a semaphore-like approach in order to prevent event handle from firing when i dont need it. Here is how it looks: private void input_TextChanged(object sender, EventArgs e) { if (_preventTextBoxEvents) return; _preventTextBoxEvents = true; //if (NullMode) // Text = ""; NullMode = false; ValidateInput(); _preventTextBoxEvents = false; } Now, if i need to set a textbox text to something that should show while in nullmode, i just set _preventTextBoxEvents before i do to true and it works all right. BUT! I need to also remove the text when user tries to input something into the textbox! So i need to set Text to "". Problem is, if i uncomment that, form is closed after the event handler exits. I cannot prevent it (e.Cancel = true in FormClosing doesnt help!) and do not understand what can be causing it. There is no error message too (and i'm not doing try-catch). My logic, when i do Text="". OnTextChanged should fire, it should call my TextChanged and it will see _preventTextBoxEvents is true and exit, so there would be no stack overflow / infinite recursion. What is going on?

  • How to return a value from facebook javascript connect api fucntions

    - by dezwald
    I am trying to create wrapper functions on facebook javascript connect api methods. My problem is that i can not return a value within the facebook api FB_RequireFeatures method. i want my isFBConnected() function to return true or false based on if i'm logged into facebook or not. What is happening is that when i return true it returns it to the child function, which makes sense however, my global "login" variable does not get set to true. I've tried setting a timeout to wait until the facebook connect finishes executing and still no luck. any help or other solutions are welcome! my isFBConnected wrapper function is stated below: function isFBConnected(){ var api_key = '<?=$this->apiKey?>'; var channel_path = '<?=$this->xdReceiver?>'; var host_url = '<?=$this->hostUrl?>'; var servicePathShort = '<?=$this->servicePathShort?>'; var login = false; FB_RequireFeatures(["Api"], function(){ // Create an ApiClient object, passing app's API key and // a site relative URL to xd_receiver.htm FB.Facebook.init(api_key, channel_path); var api = FB.Facebook.apiClient; // If FB user session exists - load stats data if(api.get_session()!=null){ if(api.get_session().uid!='' && api.get_session().uid!=undefined){ login = true; alert(api.get_session().uid); return true; } } login = false; return false; }); return false; }

  • Hibernate updating records and implementing listeners : getting only required attribute values for event.getOldState()

    - by Narendra
    Hi All, I am using Hibernate 3 as my persistence framework. Below is the sample hbm file I am using. <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping> <class name="com.test.User" table="user"> <meta attribute="implements">com.test.dao.interfaces.IEntity</meta> <id name="key" type="long" column="user_key"> <generator class="increment" /> </id> <property name="userName" column="user_name" not-null="true" type="string" /> <property name="password" column="password" not-null="true" type="string" /> <property name="firstName" column="first_name" not-null="true" type="string" /> <property name="lastName" column="last_name" not-null="true" type="string" /> <property name="createdDate" column="created_date" not-null="true" type="timestamp" insert="false" update="false" /> <property name="createdBy" column="created_by" not-null="true" type="string" update="false" /> </class> </hibernate-mapping> I am added a post-update listener. What it will do is if there any updations perfomed on User then it will be invoked and cahnges will be inserted to audit table. Below is the sample implementation for postupdate event. public void onPostUpdate(PostUpdateEvent event) { LogHelper.info(logger, "Begin - onPostUpdate " + event.getEntity().getClass().getSimpleName()); if (!this.checkForAudit(event.getEntity().getClass().getSimpleName())) { // check do we need to audit it. } // Get Attribute Names String[] attrNames = event.getPersister().getEntityMetamodel() .getPropertyNames(); Object[] oldobjectValue = c Object[] newObjectValue = event.getState(); this.auditDetailsEvent(attrNames, oldobjectValue, newObjectValue); LogHelper.info(logger, "End - onPostUpdate"); // return false; } Here is my requirement. event.getPersister().getEntityMetamodel() .getPropertyNames(); or event.getOldState(); or event.getState(); must return attribute names or value which i can update or insert. Is there any way to control the return values of above one's. Pleas help me on this regard. Thanks, Narendra

  • one table is shared between several websites

    - by sami
    I have a static table that's shared by several websites. By static, I mean that the data is read but never updated by the websites. Currently, all websites are served from the same server but that may change. I want to minimize the need for creating/maintaining this table for each of the websites, so I thought about turning it to an xml file that's stored in a shared library that all websites have access to. The problem is I use an ORM and use forign key constraints to ensure integrity of the ids used from that table, so by removing that table out of the MySQL database into an XML file, will this affect the integrity of the ids coming from that table? My table looks like this <table name="entry"> <column name="id" type="INTEGER" primaryKey="true" autoIncrement="true" /> <column name="title" type="VARCHAR" size="500" required="true" /> </table> and I use it as a foreign key in other tables <table name="refer"> <column name="id" type="INTEGER" primaryKey="true" autoIncrement="true" /> <column name="linkto" type="INTEGER"/> <foreign-key foreignTable="entry"> <reference local="linkto" foreign="id" /> </foreign-key> </table> So I'm wondering if I remove that table out of the database, is there a way to retain that referential integrity? And of course are these any other efficient ways to do the same thing? I just don't want to have to repeat that table for several websites.

  • Stopping the animation after you let go of a key

    What I have right now is an animation that starts when I press space: if(input.isKeyDown(Input.KEY_SPACE)) player = movingRightSwingingSword; However when I stop clicking space my animation continues. until I move my player, how do I make it so it stops the animation right when you let go of space?

  • Can a page opt out of IIS 7 compression?

    - by Glen Little
    My pages are automatically being compressed by IIS7 with GZIP. That is great... but, for one particular page, I need to stream it to the user, using Response.Flush() when needed. But when the output is being compressed, the IIS server seems to collect all my output until the page is done before compressing and sending it to the client. That nullifies my attempt to Flush the content out to the user. Is there a way that I can have this one page opt out of the compression? One possible option I've determined that if I manually set the content type to one that does not match the IIS configuration at c:\windows\system32\inetsrv\config\applicationhost.config, then IIS will not compress it. Eg. Response.ContentType = "x-text/html". This works okay with IE8, as it falls back to display the HTML. But Firefox will ask the user what to do with the unknown file type. This could work, if there was another Mime Type I could use that browsers would accept as HTML, that is not matched in the applicationhost.config. For reference, these are the mime types that will be compressed: <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/x-javascript" enabled="true" /> <add mimeType="application/atom+xml" enabled="true" /> <add mimeType="application/xaml+xml" enabled="true" /> Others options? Are there other options to opt out of compression?

  • What's the best way to unit test code that generates random output?

    - by Flynn1179
    Specifically, I've got a method picks n items from a list in such a way that a% of them meet one criterion, and b% meet a second, and so on. A simplified example would be to pick 5 items where 50% have a given property with the value 'true', and 50% 'false'; 50% of the time the method would return 2 true/3 false, and the other 50%, 3 true/2 false. Statistically speaking, this means that over 100 runs, I should get about 250 true/250 false, but because of the randomness, 240/260 is entirely possible. What's the best way to unit test this? I'm assuming that even though technically 300/200 is possible, it should probably fail the test if this happens. Is there a generally accepted tolerance for cases like this, and if so, how do you determine what that is?

  • Hide/Show problems on a questionerre application

    I am doing an assignment involving the creation of a simple Quiz type form application. However, whenever I run the program, only the first answer shows for a multiple question and I cannot for the life of me figure out why. This is the contstructor: MultipleChoice dlg = new MultipleChoice( new Question("What is the capital of Zimbabwe?", new Answer("Paris", false), new Answer("Washington D.C.", false), new Answer("Harare", true), new Answer("Cairo", false), new Answer("N'Djamena", false))); if (dlg.ShowDialog() == DialogResult.OK) { if (dlg.Correct) MessageBox.Show("You got something right!"); else MessageBox.Show("You couldn't be more wrong"); } And this is the Question Form Code: private Question Q; public MultipleChoice (Question q) { Q = q; InitializeComponent(); textPrompt.Text = Q.Prompt; if (Q.A != null) { radioA.Text = Q.A.Prompt; } else radioA.Hide(); if (Q.B != null) { radioB.Text = Q.B.Prompt; } radioB.Hide(); if (Q.C != null) { radioC.Text = Q.C.Prompt; } radioC.Hide(); if (Q.D != null) { radioD.Text = Q.D.Prompt; } radioD.Hide(); if (Q.E != null) { radioE.Text = Q.E.Prompt; } radioE.Hide(); } public bool Correct { get { if (Q == null) return false; if (Q.A != null && Q.A.Correct && radioA.Checked) return true; if (Q.B != null && Q.B.Correct && radioB.Checked) return true; if (Q.C != null && Q.C.Correct && radioC.Checked) return true; if (Q.D != null && Q.D.Correct && radioD.Checked) return true; if (Q.E != null && Q.E.Correct && radioE.Checked) return true; return false; } Where have I gone wrong?

  • jQuery > Update inline script on form submission

    - by Andrew Kirk
    I am using the ChemDoodle Web Components to display molecules on a web page. Basically, I can just insert the following script in my page and it will create an HTML5 canvas element to display the molecule. <script> var transform1 = new TransformCanvas('transform1', 200, 200, true); transform1.specs.bonds_useJMOLColors = true; transform1.specs.bonds_width_2D = 3; transform1.specs.atoms_useJMOLColors = true; transform1.specs.atoms_circles_2D = true; transform1.specs.backgroundColor = 'black'; transform1.specs.bonds_clearOverlaps_2D = true; transform1.loadMolecule(readPDB(molecule)); </script> In this example, "molecule" is a variable that I have defined in an external script by using the jQuery.ajax() function to load a PDB file. This is all fine and good. Now, I would like to include a form on the page that will allow a user to paste in a PDB molecule definition. Upon submitting the form, I want to update the "molecule" variable with the form data so that the ChemDoodle Web Components script will work its magic and display molecule defined by the PDB definition pasted into the form. I am using the following jQuery code to process the the form submission. $(".button").click(function() { // validate and process form here //hide previous errors $('.error').hide(); //validate pdb textarea field var pdb = $("textarea#pdb").val(); if (pdb == "") { $("label#pdb_error").show(); $("textarea#pdb").focus(); return false; } molecule = pdb; }); This code is setting the "molecule" variable upon the form submission but it is not being passed back to the inline script as I had hoped. I have tried a number of variations on this but can't seem to get it right. Any clues as to where I might be going wrong would be much appreciated.

  • How can I pass query string variables with NavigationService.Navigate?

    - by Mike Hildner
    Greetings, Searched for this, but no luck. I'm attempting to pass query string variables (and then retrieve them) in my Silverlight 4 app. First I tried this this.NavigationService.Navigate(new Uri("/LoanProductionRegion?Elvis=Alive&ImHungry=true", UriKind.Relative)); But HtmlPage.Document.QueryString doesn't pick them up because they come after the anchor (the full url looks like http://localhost:1076/Dashboard.SLTestPage.aspx#/LoanProductionRegion?Elvis=Alive&ImHungry=true). I tried to put the vars in front, such as this.NavigationService.Navigate(new Uri("?Elvis=Alive&ImHungry=true/LoanProductionRegion", UriKind.Relative)); this.NavigationService.Navigate(new Uri("/?Elvis=Alive&ImHungry=true/LoanProductionRegion", UriKind.Relative)); But both result in a "Page not found" error. Anyone know how to achieve what I'm after?

  • exclude private property from print_r or object?

    - by Hailwood
    Basically I am using Code Igniter, and the Code Igniter base class is huge, when I print_r some of my objects they have the base class embedded inside them. this makes it a pain to get the information I actually wanted (the rest of the properties). So, I am wondering if there is a way I can hide, or remove the base class object? I have tried clone $object; unset($object->ci); print_r($object); but of course the ci property is private. the actual function I am using for dumping is: /** * Outputs the given variables with formatting and location.

  • What are the Ruby Gotchas a newbie should be warned about?

    - by MiniQuark
    I have recently learned the Ruby programming language, and all in all it is a good language. But I was quite surprised to see that it was not as simple as I had expected. More precisely, the "rule of least-surprise" did not seem very respected to me (of course this is quite subjective). For example: x = true and false puts x # displays true! and the famous: puts "zero is true!" if 0 # zero is true! What are the other "Gotchas" you would warn a Ruby newbie about?

  • Django - foreignkey problem

    - by realshadow
    Hey, Imagine you have this model: class Category(models.Model): node_id = models.IntegerField(primary_key = True) type_id = models.IntegerField(max_length = 20) parent_id = models.IntegerField(max_length = 20) sort_order = models.IntegerField(max_length = 20) name = models.CharField(max_length = 45) lft = models.IntegerField(max_length = 20) rgt = models.IntegerField(max_length = 20) depth = models.IntegerField(max_length = 20) added_on = models.DateTimeField(auto_now = True) updated_on = models.DateTimeField(auto_now = True) status = models.IntegerField(max_length = 20) node = models.ForeignKey(Category_info, verbose_name = 'Category_info', to_field = 'node_id' The important part is the foreignkey. When I try: Category.objects.filter(type_id = type_g.type_id, parent_id = offset, status = 1) I get an error that get returned more than category, which is fine, because it is supposed to return more than one. But I want to filter the results trough another field, which would be type id (from the second Model) Here it is: class Category_info(models.Model): objtree_label_id = models.AutoField(primary_key = True) node_id = models.IntegerField(unique = True) language_id = models.IntegerField() label = models.CharField(max_length = 255) type_id = models.IntegerField() The type_id can be any number from 1 - 5. I am desparately trying to get only one result where the type_id would be number 1. Here is what I want in sql: SELECT n.*, l.* FROM objtree_nodes n JOIN objtree_labels l ON (n.node_id = l.node_id) WHERE n.type_id = 15 AND n.parent_id = 50 AND l.type_id = 1 Any help is GREATLY appreciated. Regards

  • Using Maven to Deploy to Weblogic Clusters

    - by Mark Sailes
    org.codehaus.mojo weblogic-maven-plugin 2.9.1 We're currently using the weblogic maven plugin successfully to deploy to our local WebLogic 9.2 instances. When we try to deploy to a remote environment we have a problem. We use a two machine cluster, with the admin server and managed server on one machine, and another managed server on a seperate machine. When your plugin uploads the application to the admin server, it doesn't copy it to the second managed server on the seperate machine. This then causes the second managed server a problem, as it cannot find the application in the location where the admin server saved it on its own machine. Config below <configuration> <adminServerHostName>${weblogic.adminServerHostName}</adminServerHostName> <adminServerPort>${weblogic.adminServerPort}</adminServerPort> <adminServerProtocol>${weblogic.adminServerProtocol}</adminServerProtocol> <userId>${weblogic.userId}</userId> <password>${weblogic.password}</password> <upload>${weblogic.upload}</upload> <remote>${weblogic.remote}</remote> <verbose>${weblogic.verbose}</verbose> <debug>${weblogic.debug}</debug> <stage>${weblogic.stage}</stage> <targetNames>${weblogic.targetNames}</targetNames> <exploded>${weblogic.exploded}</exploded> </configuration> <profile> <id>localhost</id> <properties> <weblogic.adminServerHostName>localhost</weblogic.adminServerHostName> <weblogic.adminServerPort>7001</weblogic.adminServerPort> <weblogic.adminServerProtocol>t3</weblogic.adminServerProtocol> <weblogic.userId>weblogic</weblogic.userId> <weblogic.password>weblogic</weblogic.password> <weblogic.upload>false</weblogic.upload> <weblogic.remote>false</weblogic.remote> <weblogic.verbose>true</weblogic.verbose> <weblogic.debug>true</weblogic.debug> <weblogic.stage>false</weblogic.stage> <weblogic.targetNames>AdminServer</weblogic.targetNames> <weblogic.exploded>false</weblogic.exploded> </properties> </profile> <profile> <id>dev</id> <properties> <weblogic.adminServerHostName>******</weblogic.adminServerHostName> <weblogic.adminServerPort>9141</weblogic.adminServerPort> <weblogic.adminServerProtocol>t3</weblogic.adminServerProtocol> <weblogic.userId>******</weblogic.userId> <weblogic.password>******</weblogic.password> <weblogic.upload>true</weblogic.upload> <weblogic.remote>true</weblogic.remote> <weblogic.verbose>true</weblogic.verbose> <weblogic.debug>true</weblogic.debug> <weblogic.stage>true</weblogic.stage> <weblogic.targetNames>dev_cluster01</weblogic.targetNames> <weblogic.exploded>false</weblogic.exploded> </properties> </profile>

  • JQuery Modal Dialog Form Submission

    - by peterwkc

  • Handling Application Logic in Multiple AsyncTask onPostExecute()s

    - by stormin986
    I have three simultaneous instances of an AsyncTask for download three files. When two particular ones finish, at the end of onPostExecute() I check a flag set by each, and if both are true, I call startActivity() for the next Activity. I am currently seeing the activity called twice, or something that resembles this type of behavior. Since the screen does that 'swipe left' kind of transition to the next activity, it sometimes does it twice (and when I hit back, it goes back to the same activity). It's obvious two versions of the activity that SHOULD only get called once are being put on the Activity stack. The only way I can find that this is possible is if both AsyncTasks' onPostExecute() executed SO simultaneously that they were virtually running the same lines at the same time, since I set the 'itemXdownloaded' flag to true right before I check for both and call startActivity(). But this is happening enough that it's very hard for me to believe that both downloads are finishing precisely at the same time and having their onPostExecute()s so close together... Any thoughts on what could be going on here? General gist of code (details removed, ignore any syntactical errors I may have edited in): // In onPostExecute() switch (downloadID) { case DL1: dl1complete = true; break; case DL2: dl2complete = true; break; case DL3: dl3complete = true; break; } // If 1 and 2 are done, move on (DL3 still going in background) if ( downloadID != DL3 && dl1complete && dl2complete) { ParentClass.this.startActivity(new Intent(ParentClass.this, NextActivity.class)); }

  • Model-layer validation in Doctrine, Symfony

    - by Andree
    Hi there, I have a schema.yml containing something similiar to the following: Character: tableName: characters actAs: { Timestampable: ~ } columns: id: { type: integer(4), primary: true, autoincrement: true } name: { type: string(255), notnull: true, notblank: true, minlength: 3 } I define the minlength of the column name to be 3. I created a unit test to test the minlength validation, and I found out that the validation is not working. $character = new Character(); $character->set('name', 'Dw'); $t->ok(! $character->isValid()); # This test failed Can someone tell me what might be the problem here? Thanks, Andree
