  • ListView created programmatically - emptyView doesn't show

    - by Yorick
    I've created custom ListView programmatically, and set view to show when ListAdapter is empty but nothing shows on the screen in that case, what can be wrong? public PlayerList(Context context, Activity activity) { super(context); mParent = activity; setOnItemClickListener( new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id) { ... } }; List<PlayerInfo> players; players = getPlayerList(); // here size of players == 0 setAdapter(new PlayersAdapter(this.getContext(), R.id.player_name, players)); LayoutInflater vi = (LayoutInflater)mParent.getSystemService(Context.LAYOUT_INFLATER_SERVICE); emptyView = vi.inflate(R.layout.empty_view, null); // emptyView is View, and member of PlayerList this.setEmptyView(emptyView); }

  • basename() returning int?

    - by EB
    Probably something stupid I'm missing but, why am I getting this warning? static void foo(char *path) { char *bname; char *path2 = strdup(path); bname = basename(path2); (line with basename() call): warning: assignment makes pointer from integer without a cast Indeed, if I change to this, the warning goes away: bname = (char *)basename(path2); man 3 basename tells me: char *basename(char *path); Both dirname() and basename() return pointers to null-terminated strings. What gives?

  • Deserializing only select properties of an Entity using JDOQL query string?

    - by user246114
    Hi, I have a rather large class stored in the datastore, for example a User class with lots of fields (I'm using java, omitting all decorations below example for clarity): @PersistenceCapable class User { private String username; private String city; private String state; private String country; private String favColor; } For some user queries, I only need the favColor property, but right now I'm doing this: SELECT FROM " + User.class.getName() + " WHERE username == 'bob' which should deserialize all of the entity properties. Is it possible to do something instead like: SELECT username, favColor FROM " + User.class.getName() + " WHERE username == 'bob' and then in this case, all of the returned User instances will only spend time deserializing the username and favColor properties, and not the city/state/country properties? If so, then I suppose all the other properties will be null (in the case of objects) or 0 for int/long/float? Thank you

    - by kwokwai
    Hi all, I am learning how to use JQuery to help check data availability. I have written a function in a Controller for checking data input, and the URL is like this: http://www.mywebsite.com/controllers/action/avariable but the returned data was blank. <Script language="javascript"> $(document).ready(function(){ $(document).change(function(){ var usr = $("#data\\[User\\]\\[name\\]").val(); $.post{"http://www.mywebsite.com/controllers/action/", usr, function(msg){alert(msg);} } }); }); </Script> <div id="username"> <input type=text name="data[User][name]" id="data[User][name]"> </div> Here is the code of the Action: function action($data=null){ $this->autoRender = false; $result2=$this->__avail($udata); if($result2==1) {return "OK";} else {return "NOT";} }

  • Why is this UL and inline JS giving errors during HTML validation?

    - by thor
    I've just run the homepage of a site I'm working on through the w3c HTML validator and it's come back with 3 errors and 2 warnings. I've taken a look at them but can't see why they would be causing a problem. I've pasted them in below (I've removed URL's/strings etc as the site isn't quite ready to be made public yet). This is being validated against XHTML Transitional by the way. The UL comes back with the following error: end tag for "ul" which is not finished <ul id='tabs'></ul> <ul id='tabs'> <li> <a href="/en/folder/folder/search?categories[]=cat1" class="tab1" title="tab_title"> <img alt="img_alt" src="img_src" /> <span> tab1_text </span> </a> </li> <li> <a href="/en/folder/folder/search?categories[]=cat2" class="tab2" title="tab_title"> <img alt="img_alt" src="img_src" /> <span> tab2_text </span> </a> </li> <li> <a href="/en/folder/folder/search?categories[]=cat3" class="tab3" title="tab_title"> <img alt="img_alt" src="img_src" /> <span> tab3_text </span> </a> </li> <li> <a href="/en/folder/folder/search?categories[]=cat4" class="tab4" title="tab_title"> <img alt="img_alt" src="img_src" /> <span> tab4_text </span> </a> </li> <li> <a href="/en/folder/folder/search?categories[]=cat5" class="tab5" title="tab_title"> <img alt="img_alt" src="img_src" /> <span> tab5_text </span> </a> </li> <li> <a href="/en/folder/folder/search?categories[]=cat6" class="tab6" title="tab_title"> <img alt="img_alt" src="img_src" /> <span> tab6_text </span> </a> </li> <li> <a href="/en/folder/folder/search?categories[]=cat7" class="tab7" title="tab_title"> <img alt="img_alt" src="img_src" /> <span> tab7_text </span> </a> </li> <li> <a href="/en/folder/folder/search?categories[]=cat8" class="tab8" title="tab_title"> <img alt="img_alt" src="img_src" /> <span> tab8_text </span> </a> </li> </ul> For the inline javascript, I'm getting 2 errors and 2 warnings all for the same thing - I have a simple if statement with && and the validator appears to be seeing this as HTML rather than javascript: character "&amp;" is the first character of a delimiter but occurred as data and xmlParseEntityRef: no name <script type='text/javascript'> if (weather_data != null && weather_data['data'] != null){ display_weather(); } </script> The javascript is placed just before the body close tag at the end of the document. If you need to see the full source then let me know and I can send it over.

  • C# Closing a form during a constructor

    - by pm_2
    Is it possible to close a form while the constructor is executing (or simply to stop it showing at this stage)? I have the following code: public partial class MyForm : Form { public MyForm() { if (MyFunc()) { this.Close(); } } } Which errors in Main(), here: static void Main() { ... // Following line errors Application.Run(new MyForm()); } I’ve tried checking the result of MyForm like this: static void Main() { ... MyForm frm = new MyForm(); if (frm != null) { // Following line errors Application.Run(frm); } } But that doesn’t seem to help. Can anyone tell me a way around this, please? Maybe a way to check the form to see if it still exists?

  • Need to get to the foreign keys of an entity marked as "Deleted" for auditing

    - by Abhijeet Patel
    I'm using v1 of EF(.NET 3.5 SP1). I'm subscribing to the SavingChanges event of the ObjectContext wherein I audit deletes for a particular entity type. I need to get to the foreign keys of the entity being deleted i.e EntityKeys of the related entities (RelatedEnds) but the EntityKeys of the related entities are nulls. Is there any way to get to the foreign keys of an entity which has been marked for deletion? Does EF null out the EntityKeys of all RelatedEnds for an entity which has been marked for deletion? If so, is there a way I can get hold of the foreign keys?

  • using NEWSEQUENTIALID() with UPDATE Trigger

    - by Ram
    I am adding a new GUID/Uniqueidentifier column to my table. ALTER TABLE table_name ADD VersionNumber UNIQUEIDENTIFIER UNIQUE NOT NULL DEFAULT NEWSEQUENTIALID() GO And when ever a record is updated in the table, I would want to update this column "VersionNumber". So I create a new trigger CREATE TRIGGER [DBO].[TR_TABLE_NAMWE] ON [DBO].[TABLE_NAME] AFTER UPDATE AS BEGIN UPDATE TABLE_NAME SET VERSIONNUMBER=NEWSEQUENTIALID() FROM TABLE_NAME D JOIN INSERTED I ON D.ID=I.ID/* some ID which is used to join*/ END GO But just realized that NEWSEQUENTIALID() can only be used with CREATE TABLE or ALTER TABLE. I got this error The newsequentialid() built-in function can only be used in a DEFAULT expression for a column of type 'uniqueidentifier' in a CREATE TABLE or ALTER TABLE statement. It cannot be combined with other operators to form a complex scalar expression. Is there a workaround for this ? Edit1: Changing NEWSEQUENTIALID() to NEWID() in the trigger solves this, but I am indexing this column and using NEWID() would be sub-optimal

  • How can I not render a button in my view if a given property off my model has no value?

    - by Lee Warner
    I'm new to web development. In my view, I want to conditionally show a button if Model.TemplateLocation (which is a string) is not null or empty. Below is the code that is rendering the button currently: <div class="WPButton MyButton"> <%=Html.ActionLink(Model.TemplateLinkName, "DownloadTemplate", "ExternalData", new ArgsDownloadTemplate { Path = Model.TemplateLocation, FileName = Model.TemplateFileNameForDownload }, new{})%> </div> Can I wrap some C# code in the <% %'s to test for Model.TemplateLocations value before I render that? I was told to look into @style = "display:none" somehow. Could that be what I need?

  • How do I conditionally assign ruby variables to javascript variables?

    - by Tony
    I have a website where I need a javascript version of the "current user" object along with the ruby version. I have been assigning these variables doing something like this... Application Controller: def get_user begin @current_user = User.find(session[:user_id]) if session[:user_id] @current_user_json = @current_user.to_json rescue session.delete(:user_id) @current_user = nil @current_user_json = {} end end Web Page: var current_user = null; current_user_json = '<%= @current_user_json %>'; if(current_user_json != ''){ current_user = current_user_json.user; } Even when there is a current user, I get the current user is undefined. Probably because I am putting the current_user_json assignment around single quotes. However, if I don't put it around single quotes, I'll always get a javascript error when no user is logged in because the syntax is invalid - current_user_json = ; I think I am just looking at this completely wrong and there must be a better way. Given that this is probably a common thing to do, I wanted to get other people's opinion on how to create an object in javascript that is a duplicate of the ruby object.

  • Two parameters in asp.net mvc route

    - by olst
    Hi. This is a modification to a question I've asked before on this forum. My controller action: public ActionResult SearchResults(string searchTerm, int page)... My view: <%= Html.PageLinks((int)ViewData["CurrentPage"], (int)ViewData["TotalPages"], i => Url.Action("SearchResults", new { page = i }))%>... The route entries: routes.MapRoute( null, "SearchResults", new { controller = "Search", action = "SearchResults", page = 1 } // Defaults ); routes.MapRoute( "Search", "SearchResults/Page{page}", new { controller = "Search", action = "SearchResults" }, new { page = @"\d+" } ); My goal is to have paging links for the search results. The problem is that when I click any page in the paging links, it gives me the search results of an empty serach term. How can I pass the search term parameter which is a string in addition to the page number parameter ? What should I put in the routing ?

  • How can i initialize an array without knowing it size?

    - by Sara
    I have a situation where i have to apply a criteria on an input array and reuturn another array as output which will have smaller size based upon the filtering criteria. Now problem is i do not know the size of filtered results, so i can not initialize the array with specific value. And i do not want it to be large size will null values because i am using array.length; later on. One way is to first loop the original input array and set a counter, and then make another loop with that counter length and initialize and fill this array[]. But is there anyway to do the job in just one loop?

  • Hudson: where to download file and stop specific builds running ?

    - by Kim Jong Woo
    I have a file that is generated inside (hudson server) /var/lib/hudson/jobs/jobtitle/1/out.txt I need to fetch this file, but doing a GET request for http://myhudson:8090/job/jobtitle/1/out.txt doesn't actually locate the file. Basically, I have another box that will grab this file from the hudson server. This box will make the out.txt file available for download. Another challenge is the build number directories. How would I be able to use the hudson API to stop or delete the specific builds running ? I am forced to do iterate through all build numbers to send STOP or DELETE api call in php using wget to do the REST API call. This is not very efficient. for ($i=0; $i < 3000; $i++){ exec('wget -O /dev/null "http://myhudson:8090/job/' . 'jobtitle' . '/$i/stop"'); }

  • Is the "message" of an exception culturally independent?

    - by Ray Hayes
    In an application I'm developing, I have the need to handle a socket-timeout differently from a general socket exception. The problem is that many different issues result in a SocketException and I need to know what the cause was. There is no inner exception reported, so the only information I have to work with is the message: "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond" This question has a general and specific part: is it acceptable to write conditional logic based upon the textual representation of an exception? Is there a way to avoid needing exception handling? Example code below... try { IPEndPoint endPoint = null; client.Client.ReceiveTimeout = 1000; bytes = client.Receive(ref endPoint); } catch( SocketException se ) { if ( se.Message.Contains("did not properly respond after a period of time") ) { // Handle timeout differently.. } }

  • Dom Element onclick (MooTools :: optionally)

    - by Theofanis Pantelides
    Consider the following example: function async_callback(array1, array2, array3) { // All arrays are equal length for(var i = 0; i < array1.length; i++) { var myElement = new Element('div', { 'id': 'dvMy' + i, 'events': { 'click': function() { SomeFunction(array1[i], array2[i], array3[i] } }}); $(document).appendChild(myElement); } } Now when I click my element, I get a null value for all three arguments. I even tried doing: myElement.onclick = SomeFunction; // but this won't allow arguments I know I can create a string and use eval() and that does work, but I don't like eval(). Any ideas??? btw: This is a simple example to replicate the problem, and not actual code.

  • jQuery mobile 1.1.0 slider: JS-object properties access?

    EDIT: This could be seen as a pure javascript objects question. The code can be found here: jquery.mobile-1.1.0.js I need to access properties of a jQuery mobile JS-object but is not sure how that is possible. In the jquery.mobile-1.1.0.js and mobile.slider is the following (see extend on line 5967): $.widget( "mobile.slider", $.mobile.widget, { ... _create: function() { ... $.extend( this, { slider: slider, handle: handle, valuebg: valuebg, dragging: false, beforeStart: null, userModified: false, mouseMoved: false }); Primarily the property I would like to read is the "dragging". I know i can execute the methods using: $("#slider").slider("refresh") Is there a similair way to access the properties? Thanks
