• Requested URL is changing

  - by user302486

  Hi, I have a website, at localhost:82 when I type this into IE, it comes up with a 404 error and the requested URL is localhost:80/wwwroot, which is not at all what I requested. There is no URL rewrite set up. I have tried to set up a tracing rule to see what is happening, however, the instructions at http://learn.iis.net/page.aspx/266/troubleshooting-failed-requests-using-tracing-in-iis-7/ say to look for "Fail Request Tracing" link, but it doesn't exist in my IIS 7.0 even under administrator. Not sure where to look or why this is changing my requested URL. Any help would be appreciated.

• Are you using Virtual Machine as your primary development enviroment?

  - by Click Ok

  Recently I have purchased a notebook that cames with Windows Home Basic (that don't have with ASP.Net/IIS. I thought in upgrade the Windows version to one with ASP.Net/IIS, but I thought in another possibility: I have an Hard Disk Case with a 360Gb HD. I thought in create a virtual machine with Windows Ultimate (installing too ASP.Net, IIS and Visual Studio 2008) in this HD Case, then I can access my "development enviroment" in any computer that I will work on (my desktop machine and my notebook). But I was worried about the performance. I don't have experience working in Virtual Machines (I use it just to quick compatibility tests)... Are you using Virtual Machine as your primary development enviroment? What your finds? ==================== Thanks for your answers! It really did help me! I would like to know too about portability ie.: the virtual machine that I created in my laptop will work in the desktop? I will need re-activate Windows?

• How do I implement .net plugins without using AppDomains?

  - by Abtin Forouzandeh

  Problem statement: Implement a plug-in system that allows the associated assemblies to be overwritten (avoid file locking). In .Net, specific assemblies may not be unloaded, only entire AppDomains may be unloaded. I'm posting this because when I was trying to solve the problem, every solution made reference to using multiple AppDomains. Multiple AppDomains are very hard to implement correctly, even when architected at the start of a project. Also, AppDomains didn't work for me because I needed to transfer Type across domains as a setting for Speech Server worfklow's InvokeWorkflow activity. Unfortunately, sending a type across domains causes the assembly to be injected into the local AppDomain. Also, this is relevant to IIS. IIS has a Shadow Copy setting that allows an executing assembly to be overwritten while its loaded into memory. The problem is that (at least under XP, didnt test on production 2003 servers) when you programmatically load an assembly, the shadow copy doesnt work (because you are loading the DLL, not IIS).

• Handler not yet determined error

  - by SourceC

  Hello, I don’t know anything about deploying a website, so I probably made some stupid mistake. Anyways, I opened IIS 7 manager, created new virtual directory ( via Add Application ) and pointed it to physical directory where Visual studio saved my Web project. But when I tried to request an .aspx page, browser reported the following error (I won’t post the whole error, but just the interesting bits): Handler: Not yet determined Config Error: Cannot read configuration file due to insufficient permissions Logon User: Not yet determined A) why is handler not yet determined? As far as I know, IIS7 does have Asp.Net handler registered?! B) Why wouldn’t IIS have sufficient permissions? Does that mean I should give IIS higher privileges? Or does Asp.Net runtime have insufficient permissions? C) Could the error also be due to the fact that perhaps it expected the user to authenticate itself? I’m assuming this due to Logon user not yet being determined? D) And finally, any ideas how to make it work? thanx

• Is it possible to configure Apache to host both an ASP.NET Web Service and a PHP Web site?

  - by Eduardo León

  Noob question (because I'm a noob when it comes to Web development). I'm not sure whether I should ask it here or at ServerFault. I am developing an ASP.NET Web Service and a PHP Web site consuming the Web Service. They are meant to be run on different machines. However, only for development purposes, I need to run both on my machine. I cannot use virtual machines. I would like to know if it is possible to configure IIS Apache to host both my Web Service and my Web site? Or, do I need to host the PHP site using Apache? I am using IIS 7.5 Apache HTTP Server 2.2 (NOTE: I have nothing against Apache. In fact, so far I like it more than IIS, however, I would rather not have two Web server applications installed in the same machine.) PHP 5.3.4 .NET Framework 2.0 3.0 or 3.5 (whichever comes with Visual Studio 2008) mod_aspdotnet for Apache 2.2

• HTTP 500 Internal Server Error on IIS 7.5 with MVC3

  - by Tor Haugen

  I am trying to install an MVC3 application on our production server with no luck. The application is from a 3rd party (compiled), and so debugging is not available to me. Besides, I strongly suspect the error occurs before any code in the site has a chance to execute. Our staging server is - as far as I can determine - set up excactly like the production server. Both run Windows Server 2008 Standard R2, both also run a Sharepoint 2010 site (though this install doesn't touch that in any way). IIS is version 7.5, and .NET Framework 4.0 (required by the MVC app) is (recently) installed (by me, with a reboot after). The application is very small and simple and, as far as I can tell sticks to fairly standard functionality - including forms authentication (ie. it doesnt' pull any dirty tricks). The error message shown in the browser is very general: HTTP Error 500.0 - Internal Server Error An error message detailing the cause of this specific request failure can be found in the application event log of the web server. Please review this log entry to discover what caused this error to occur. The bit about 'An error message detailing the cause' being in the application event log seems to be just speculation - a pious hope that whatever code actually caused the error will log it. Nothing useful is to be found in the event log (only the very same message, logged by IIS). Module: AspNetInitClrHostFailureModule Notification: BeginRequest Handler: StaticFile Error Code: 0x80070002 Requested URL: http://xxxxxx.xxxxxx.xx:80/ Physical Path: C:\Xxxxxxx\Prod\WebClient Logon Method: Not yet determined Logon User: Not yet determined Using Failed Request Tracing, I have been able to track the error (as also indicated above) to the AspNetInitClrHostFailureModule: 103. -NOTIFY_MODULE_START ModuleName AspNetInitClrHostFailureModule Notification 1 fIsPostNotification false Notification BEGIN_REQUEST 104. -SET_RESPONSE_ERROR_DESCRIPTION ErrorDescription An error message detailing the cause of this specific request failure can be found in the application event log of the web server. Please review this log entry to discover what caused this error to occur. 105. -MODULE_SET_RESPONSE_ERROR_STATUS ModuleName AspNetInitClrHostFailureModule Notification 1 HttpStatus 500 HttpReason Internal Server Error HttpSubStatus 0 ErrorCode 2147942402 ConfigExceptionInfo Notification BEGIN_REQUEST ErrorCode The system cannot find the file specified. (0x80070002) So there you have it. Seemingly, the AspNetInitClrHostFailureModule fails to find some file. So some questions are: What is the AspNetInitClrHostFailureModule? It is not listed in the fairly exhausting list of modules configurable in IIS manager for the site. I have had no success googling it either. Maybe it's secret.. I access the root URL of the site. This is supposed to be redirected to /Account/LogOn by the FormsAuthenticationModule. Why then is the handler StaticFile? Is that a clue? I have tried removing the infamous system.webserver/modules/runAllManagedModulesForAllRequests attribute, and that makes the error go away (but MVC not actually working, of course). I am prepared to specify all necessary modules manually if that's what it takes, but if the AspNetInitClrHostFailureModule is actually needed, I will be just as stuck. Does anyone know, or can anyone direct me to someone who knows, exactly what modules a typical MVC3 application actually needs? This question might well be a duplicate of this one, but he didn't get any useful answer, and also asked less specific questions. So I'll have my own go. Hoping for some help here :) Edit: I have now tried setting up a trivial MVC 3 project on the server. I created a new project using the MVC Application template, compiled it and deployed it to the server. It behaves in exactly the same way. The server simply cannot run MVC 3 projects.

• inews failed: "No colon-space in "X-MS-TNEF-Correlator:"

  - by wolfgangsz

  We run a news server for our engineering teams, which is also linked to the code repositories (so that all engineers can subscribe to any changes in the repos or just the projects they are interested in). On quite a regular basis (several times a day) I (as the sysadmin for that server) receive bounces from innd with the above as the first line. The news server simply rejects these messages and the articles don't get posted. Here is an example: inews failed: inews: cannot send article to server: 441 437 No colon-space in "X-MS-TNEF-Correlator:" header inews: article not posted -------- Article Contents Path: aminocom.com!ctaylor From: [email protected] (Cameron Taylor) Newsgroups: amino.qa.reports Content-Language: en-US Content-Type: multipart/alternative; boundary="_000_A2AB95742ADD524795C13EDE8F8CCD201A798C0Eukswaex01_" MIME-Version: 1.0 Subject: [QA REPORT] MDK 400 release 3.4.33 **PRE-RELEASE** Message-ID: Date: Thu, 9 Sep 2010 16:15:16 +0000 X-Received: from uk-swa-ex02.aminocom.com (uk-swa-ex02.aminocom.com [10.171.3.10]) by theoline.aminocom.com (8.14.3/8.13.8) with ESMTP id o89GF8tx019494 for ; Thu, 9 Sep 2010 17:15:08 +0100 X-Received: from uk-swa-ex01.aminocom.com ([10.171.3.9]) by uk-swa-ex02 ([10.171.3.10]) with mapi; Thu, 9 Sep 2010 17:15:18 +0100 X-To: QA Reports X-Thread-Topic: [QA REPORT] MDK 400 release 3.4.33 **PRE-RELEASE** X-Thread-Index: ActQOjBdms0CSJsORNSxRIMSZ4H3Ow== X-Accept-Language: en-US, en-GB X-MS-Has-Attach: X-MS-TNEF-Correlator: X-Auto-Response-Suppress: DR, OOF, AutoReply --_000_A2AB95742ADD524795C13EDE8F8CCD201A798C0Eukswaex01_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable SQA Test Report [QA REPORT] MDK 400 release 3.4.33 **PRE-RELEASE** Status .... (rest of the message is not important) And yes, quite clearly this header doesn't have anything after the colon. The man page for innd doesn't specify why it rejects these messages, it just says it rejects them. So far I have found out these headers are linked to messages in RTF format (coming from Outlook clients), where normally the formatting information would be stored in a winmail.dat attachment. The clients all use MS Exchange 2010 servers to send their mail (identified above as uk-swa-ex02.aminocom.com) which forwards the message to the news server. Does anybody know what advice I need to give these users to avoid their articles getting bounced? Or can I change the behaviour of innd? Or do I need to filter these headers out before innd processes the articles?

• Routing generated paths in Ruby on Rails

  - by True Soft

  I'm a beginner in ruby-on-rails and I spent my last hour trying to do the following thing: I have a ruby-on-rails application - the blog with posts and categories. I want to have another URL for the posts (I would like to have http://localhost:3000/news instead of http://localhost:3000/posts) First I tried to replace the controller and classes from Posts to News, but I gave up(because of the annoyng singular-plural thing). Then in my I replaced map.resources :posts (case 1) to map.resources :news, :controller => "posts" #case 2 or map.resources :posts, :as => 'news' #case 3 in routes.rb as I saw on some websites. It doesn't work either. How can I do this? EDIT: the output of rake routes is (only first lines): for case 1 and 3: posts GET /posts {:action=>"index", :controller=>"posts"} formatted_posts GET /posts.:format {:action=>"index", :controller=>"posts"} POST /posts {:action=>"create", :controller=>"posts"} POST /posts.:format {:action=>"create", :controller=>"posts"} new_post GET /posts/new {:action=>"new", :controller=>"posts"} formatted_new_post GET /posts/new.:format {:action=>"new", :controller=>"posts"} edit_post GET /posts/:id/edit {:action=>"edit", :controller=>"posts"} formatted_edit_post GET /posts/:id/edit.:format {:action=>"edit", :controller=>"posts"} post GET /posts/:id {:action=>"show", :controller=>"posts"} formatted_post GET /posts/:id.:format {:action=>"show", :controller=>"posts"} PUT /posts/:id {:action=>"update", :controller=>"posts"} PUT /posts/:id.:format {:action=>"update", :controller=>"posts"} DELETE /posts/:id {:action=>"destroy", :controller=>"posts"} DELETE /posts/:id.:format {:action=>"destroy", :controller=>"posts"} the output for case 2: news_index GET /news {:action=>"index", :controller=>"posts"} formatted_news_index GET /news.:format {:action=>"index", :controller=>"posts"} POST /news {:action=>"create", :controller=>"posts"} POST /news.:format {:action=>"create", :controller=>"posts"} new_news GET /news/new {:action=>"new", :controller=>"posts"} formatted_new_news GET /news/new.:format {:action=>"new", :controller=>"posts"} edit_news GET /news/:id/edit {:action=>"edit", :controller=>"posts"} formatted_edit_news GET /news/:id/edit.:format {:action=>"edit", :controller=>"posts"} news GET /news/:id {:action=>"show", :controller=>"posts"} formatted_news GET /news/:id.:format {:action=>"show", :controller=>"posts"} PUT /news/:id {:action=>"update", :controller=>"posts"} PUT /news/:id.:format {:action=>"update", :controller=>"posts"} DELETE /news/:id {:action=>"destroy", :controller=>"posts"} DELETE /news/:id.:format {:action=>"destroy", :controller=>"posts"} I have errors in case 2, because in my sourcecode I don't have edit_news, I have for example <%= link_to 'Edit', edit_post_path(post) %>

• (SQL) Selecting from a database based on multiple pairs of pairs

  - by Owen Allen

  The problem i've encountered is attempting to select rows from a database where 2 columns in that row align to specific pairs of data. IE selecting rows from data where id = 1 AND type = 'news'. Obviously, if it was 1 simple pair it would be easy, but the issue is we are selecting rows based on 100s of pair of data. I feel as if there must be some way to do this query without looping through the pairs and querying each individually. I'm hoping some SQL stackers can provide guidance. Here's a full code break down: Lets imagine that I have the following dataset where history_id is the primary key. I simplified the structure a bit regarding the dates for ease of reading. table: history history_id id type user_id date 1 1 news 1 5/1 2 1 news 1 5/1 3 1 photo 1 5/2 4 3 news 1 5/3 5 4 news 1 5/3 6 1 news 1 5/4 7 2 photo 1 5/4 8 2 photo 1 5/5 If the user wants to select rows from the database based on a date range we would take a subset of that data. SELECT history_id, id, type, user_id, date FROM history WHERE date BETWEEN '5/3' AND '5/5' Which returns the following dataset history_id id type user_id date 4 3 news 1 5/3 5 4 news 1 5/3 6 1 news 1 5/4 7 2 photo 1 5/4 8 2 photo 1 5/5 Now, using that subset of data I need to determine how many of those entries represent the first entry in the database for each type,id pairing. IE is row 4 the first time in the database that id: 3, type: news appears. So I use a with() min() query. In real code the two lists are programmatically generated from the result sets of our previous query, here I spelled them out for ease of reading. WITH previous AS ( SELECT history_id, id, type FROM history WHERE id IN (1,2,3,4) AND type IN ('news','photo') ) SELECT min(history_id) as history_id, id, type FROM previous GROUP BY id, type Which returns the following data set. history_id id type user_id date 1 1 news 1 5/1 2 1 news 1 5/1 3 1 photo 1 5/2 4 3 news 1 5/3 5 4 news 1 5/3 6 1 news 1 5/4 7 2 photo 1 5/4 8 2 photo 1 5/5 You'll notice it's the entire original dataset, because we are matching id and type individually in lists, rather than as a collective pairs. The result I desire is, but I can't figure out the SQL to get this result. history_id id type user_id date 1 1 news 1 5/1 4 3 news 1 5/3 5 4 news 1 5/3 7 2 photo 1 5/4 Obviously, I could go the route of looping through each pair and querying the database to determine it's first result, but that seems an inefficient solution. I figured one of the SQL gurus on this site might be able to spread some wisdom. In case I'm approaching this situation incorrectly, the gist of the whole routine is that the database stores all creations and edits in the same table. I need to track each users behavior and determine how many entries in the history table are edits or creations over a specific date range. Therefore I select all type:id pairs from the date range based on a user_id, and then for each pairing I determine if the user is responsible for the first that occurs in the database. If first, then creation else edit. Any assistance would be awesome.

• IIS error hosting WCF Data Service on shared web host

  - by jkohlhepp

  My client has a website hosted on a shared web server. I don't have access to IIS. I am trying to deploy a WCF Data Service onto his site. I am getting this error: IIS specified authentication schemes 'IntegratedWindowsAuthentication, Anonymous', but the binding only supports specification of exactly one authentication scheme. Valid authentication schemes are Digest, Negotiate, NTLM, Basic, or Anonymous. Change the IIS settings so that only a single authentication scheme is used. I have searched SO and other sites quite a bit but can't seem to find someone with my exact situation. I cannot change the IIS settings because this is a third party's server and it is a shared web server. So my only option is to change things in code or in the service config. My service config looks like this: <system.serviceModel xdt:Transform="Insert"> <serviceHostingEnvironment> <baseAddressPrefixFilters> <add prefix="http://www.somewebsite.com"/> </baseAddressPrefixFilters> </serviceHostingEnvironment> <bindings> <webHttpBinding> <binding name="{Binding Name}" > <security mode="None" /> </binding> </webHttpBinding> </bindings> <services> <service name="{Namespace to Service}"> <endpoint address="" binding="webHttpBinding" bindingConfiguration="{Binding Name}" contract="System.Data.Services.IRequestHandler"> </endpoint> </service> </services> </system.serviceModel> As you can see I tried to set the security mode to "None" but that didn't seem to help. What should I change to resolve this error?

• Stackpanel add item animation

  - by grzegorz_p

  Hello, I've been struggling a while with marquee-style image scrolling control. At a moment, I stuck up with templated ItemsControl: <Window.Resources> <DataTemplate x:Key="itemsTemplate"> <Image Source="{Binding AbsolutePath}"></Image> </DataTemplate> </Window.Resources> <ItemsControl ItemTemplate="{StaticResource itemsTemplate}" x:Name="ic" ItemsSource="{Binding ElementName=mainWindow, Path=DataItems}" VirtualizingStackPanel.IsVirtualizing="True"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <VirtualizingStackPanel Orientation="Vertical" VerticalAlignment="Bottom" VirtualizingStackPanel.IsVirtualizing="True" > </VirtualizingStackPanel> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> ItemsControl is bound to ObservableCollection, so I can add items at runtime. As soon as item goes off-screen it's removed from ObservableCollection. The last thing to do is implementing custom item add behavior (smooth slide-in instead of insert-translateothers behavior). Shall I derive from StackPanel to achieve such effect or just perform DoubleAnimation on currently adding item? Any suggestions appreciated.

• PCRE/PHP regex not matching last "item"

  - by superbarney

  Here's a regex that I've cobbled up: /(.*={76}\s)?\s*(.*?)\s\-\-\s(\d{2}\/\d{2}\-\d{2}\s\d{2}:\d{2})\s\s(.*?)\s(http:\/\/service.*?)\s(\-{76})/is and here's the text I will be parsing: http://p.linode.com/7015 and here's the replacement for the matched text: <item>\n\t<title>$2</title>\n\t<pubDate>$pubDate</pubDate>\n\t<description>$4</description>\n\t<link>$5</link>\n</item>\n\n I have almost come up with a regex needed to parse a block of text into RSS 2.0 XML markup. I've tested it with RegExr and RegexBuddy and it works perfectly except for the last "item" where there is no line breaks after the link (Line 269). In short, the problem is the "iProperty" article in the text is not matched. Any regex gurus willing to help me troubleshoot what's wrong? I've tried /(.*={76}\s)?\s*(.*?)\s\-\-\s(\d{2}\/\d{2}\-\d{2}\s\d{2}:\d{2})\s\s(.*?)\s(http:\/\/service.*?)\s*(\-{76})/is Here's the output that I get: http://p.linode.com/7016 but that didn't work as I expected (i.e. a newline would be optional). Thanks!

• adding header row to gridview won't allow you to save the last item row

  - by Lex

  I've modified my GridView to have an extra Header row, however that extra row has caused my grid view row count to be incorrect. Basically, when I want to save the Gridview now, it doesn't recognize the last item line. In my current test I have 5 Item Lines, however only 4 of them are being saved. My code for creating the additional header Line: protected void gvStatusReport_RowDataBound(object sender, GridViewRowEventArgs e) { // This grid has multiple rows, fake the top row. if (e.Row.RowType == DataControlRowType.Header) { SortedList FormatCells = new SortedList(); FormatCells.Add("1", ",6,1"); FormatCells.Add("2", "Time Spent,7,1"); FormatCells.Add("3", "Total,2,1"); FormatCells.Add("4", ",6,1"); GetMultiRowHeader(e, FormatCells); } } The function to create a new row: public void GetMultiRowHeader(GridViewRowEventArgs e, SortedList GetCels) { GridViewRow row; IDictionaryEnumerator enumCels = GetCels.GetEnumerator(); row = new GridViewRow(-1, -1, DataControlRowType.Header, DataControlRowState.Normal); while (enumCels.MoveNext()) { string[] count = enumCels.Value.ToString().Split(Convert.ToChar(",")); TableCell cell = new TableCell(); cell.RowSpan = Convert.ToInt16(count[2].ToString()); cell.ColumnSpan = Convert.ToInt16(count[1].ToString()); cell.Controls.Add(new LiteralControl(count[0].ToString())); cell.HorizontalAlign = HorizontalAlign.Center; row.Cells.Add(cell); } e.Row.Parent.Controls.AddAt(0, row); } Then when I'm going to save, I loop through the rows: int totalRows = gvStatusReport.Rows.Count; for (int rowNumber = 0; rowNumber < totalRows; rowNumber++) { However the first line doesn't seem to have any of the columns that the item row has, and the last line doesn't even show up. My problem is that I do need the extra header line, but what is the best way to fix this?

• Coding the Python way

  - by Aaron Moodie

  I've just spent the last half semester at Uni learning python. I've really enjoyed it, and was hoping for a few tips on how to write more 'pythonic' code. This is the __init__ class from a recent assignment I did. At the time I wrote it, I was trying to work out how I could re-write this using lambdas, or in a neater, more efficient way, but ran out of time. def __init__(self, dir): def _read_files(_, dir, files): for file in files: if file == "classes.txt": class_list = readtable(dir+"/"+file) for item in class_list: Enrol.class_info_dict[item[0]] = item[1:] if item[1] in Enrol.classes_dict: Enrol.classes_dict[item[1]].append(item[0]) else: Enrol.classes_dict[item[1]] = [item[0]] elif file == "subjects.txt": subject_list = readtable(dir+"/"+file) for item in subject_list: Enrol.subjects_dict[item[0]] = item[1] elif file == "venues.txt": venue_list = readtable(dir+"/"+file) for item in venue_list: Enrol.venues_dict[item[0]] = item[1:] elif file.endswith('.roll'): roll_list = readlines(dir+"/"+file) file = os.path.splitext(file)[0] Enrol.class_roll_dict[file] = roll_list for item in roll_list: if item in Enrol.enrolled_dict: Enrol.enrolled_dict[item].append(file) else: Enrol.enrolled_dict[item] = [file] try: os.path.walk(dir, _read_files, None) except: print "There was a problem reading the directory" As you can see, it's a little bulky. If anyone has the time or inclination, I'd really appreciate a few tips on some python best-practices. Thanks.

• Hiding a Bar button item in the view

  - by devb0yax

  How can you able to hide the (done) bar button item in a view? Basically, I have a view controller added with navigation bar (in IB) then, I also added a bar button item into the nav bar. I just want initially the (done) bar button item is hidden.. when input is in the text view the (done) button is already visible. Any idea on this implementation on a view controller? Here's my sample code: @interface MyTextViewViewController : UIViewController <UITextViewDelegate> { UITextView *m_textView; UIBarButtonItem *doneBarButtonItem; } @property(nonatomic,retain) IBOutlet UITextView *m_textView; @property(nonatomic,retain) IBOutlet UIBarButtonItem *doneBarButtonItem; - (IBAction)saveAction:(id)sender; .m file: - (void)viewDidLoad { [super viewDidLoad]; doneBarButtonItem.hidden = YES; --> compile error!!! } - (void)textViewDidBeginEditing:(UITextView *)textView { doneBarButtonItem.hidden = NO; --> compile error!!! } - (IBAction)saveAction:(id)sender { doneBarButtonItem.hidden = YES; --> compile error!!! ... }

• Android ListView: how to select an item?

  - by mmo

  I am having trouble with a ListView I created: I want an item to get selected when I click on it. My code for this looks like: protected void onResume() { ... ListView lv = getListView(); lv.setOnItemSelectedListener(new OnItemSelectedListener() { public void onItemSelected(AdapterView<?> adapterView, View view, int pos, long id) { Log.v(TAG, "onItemSelected(..., " + pos + ",...) => selected: " + getSelectedItemPosition()); } public void onNothingSelected(AdapterView<?> adapterView) { Log.v(TAG, "onNothingSelected(...) => selected: " + getSelectedItemPosition()); } }); lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> adapterView, View view, int pos, long id) { lv.setSelection(pos); Log.v(TAG, "onItemClick(..., " + pos + ",...) => selected: " + getSelectedItemPosition()); } }); ... } When I run this and click e.g. on the second item (i.e. pos=1) I get: 04-03 23:08:36.994: V/DisplayLists(663): onItemClick(..., 1,...) => selected: -1 i.e. even though the OnItemClickListener is called with the proper argument and calls a setSelection(1), there is no item selected (and hence also OnItemSelectedListener.onItemSelected(...) is never called) and getSelectedItemPosition() still yields -1 after the setSelection(1)-call. What am I missing? Michael PS.: My list does have =2 elements...

• WPF - Dynamically access a specific item of a collection in XAML

  - by Andy T

  Hi, I have a data source ('SampleAppearanceDefinitions'), which holds a single collection ('Definitions'). Each item in the collection has several properties, including Color, which is what I'm interested in here. I want, in XAML, to display the Color of a particular item in the collection as text. I can do this just fine using this code below... Text="{Binding Source={StaticResource SampleAppearanceDefinitions}, Path=Definitions[0].Color}" The only problem is, this requires me to hard-code the index of the item in the Definitions collection (I've used 0 in the example above). What I want to do in fact is to get that value from a property in my current DataContext ('AppearanceID'). One might imagine the correct code to look like this.... Text="{Binding Source={StaticResource SampleAppearanceDefinitions}, Path=Definitions[{Binding AppearanceID}].Color}" ...but of course, this is wrong. Can anyone tell me what the correct way to do this is? Is it possible in XAML only? It feels like it ought to be, but I can't work out or find how to do it. Any help would be greatly appreciated! Thanks! AT

• Access problems with IIS 7 and a WCF service

  - by Steve

  I have a Silverlight app that calls a WCF service, the service calls some stored procedures in an SQL db using Visual Studio 2008's Link to SQL class and returns the information to whatever called it. I have set up the compiled project (website with embedded app and the WCF service) on an remote IIS 7 server. I recompiled my local copy to use the WCF service that is now hosted on the IIS box and not the one on the local dev server that Visual Studio provides, if I use the local version of the website (hosted on the dev server, and using the remote SCF service) it is able to make calls it needs and display the information. However, if I use the website that is being hosted by the remote IIS server, the app will not get the information it needs from the service. On the IIS server I have the application pool and the website running under my credentials, which have access to the database. Users connecting to the webpage use anonymous authentication. Any ideas as to why I can only access the service when running from the dev server and not through the remotely hosted webpage are appreciated. If anything needs clarification, please ask.

• How to update a string property of an sqlite database item

  - by Thomas Joos

  hi all, I'm trying to write an application that checks if there is an active internet connection. If so it reads an xml and checks every 'lastupdated' item ( php generated string ). It compares it to the database items and if there is a new value, this particular item needs to be updated. My code seems to work ( compiles, no error messages, no failures, .. ) but I notice that the particular property does not change, it becomese (null). When I output the binded string value it returns the correct string value I want to update into the db.. Any idea what I'm doing wrong? const char *sql = "update myTable Set last_updated=? Where node_id =?"; sqlite3_stmt *statement; // Preparing a statement compiles the SQL query into a byte-code program in the SQLite library. // The third parameter is either the length of the SQL string or -1 to read up to the first null terminator. if (sqlite3_prepare_v2(database, sql, -1, &statement, NULL) == SQLITE_OK){ NSLog(@"last updated item: %@", [d lastupdated]); sqlite3_bind_text(statement, 1, [d lastupdated],-1,SQLITE_TRANSIENT); sqlite3_bind_int (statement, 2, [d node_id]); }else { NSLog(@"SQLite statement error!"); } if(SQLITE_DONE != sqlite3_step(statement)){ NSAssert1(0, @"Error while updating. '%s'", sqlite3_errmsg(database)); }else { NSLog(@"SQLite Update done!"); }

• Isotope.js help: Changing item image after sorting

  - by user3643081

  This is a general question on how to go about building a project I have in mind, and the best way to set off on the right foot. I am fairly new to JS, please be gentle. I want to use isotope.js (or a similar script) to display a page with multiple items (about 30 different plants found in a garden) and the ability to sort them by seasons of the year + "what is most beautiful now" + and "view all" (a total of 6 categories) . On load, or when sorted by either "what is beautiful now" or "view all", I need each item to reflect the image of the current season we are in. When sorted by season, I need those "current" images to switch over to a designated seasonal image of that plant. Therefore, each sortable item will ultimately have 4 different versions with 4 different images in the background ready to surface when plants are sorted. (perhaps 5 if it makes more sense to have a "current" version besides the 4 seasonal versions.) My question: what approach can I take to achieve this effect in a manageable way? Can isotope apply a class to items sorted? Assuming it can: Should each item have 4 inline images, each with a css class, that I then control by using display:inline; and display:none; properties from my stylesheets? (I worry that this approach would significantly increase load times) Would it make more sense to create a blank dummy div who's background I control similarly to the example above -relying mostly on CSS. Or is there some other way involving JS I am overlooking? Any help would be appreciated. Examples of what you suggest would be immensely helpful.

• Getting the current item number or index when using will_paginate in rails app

  - by Rich

  I have a rails app that stores movies watched, books read, etc. The index page for each type lists paged collections of all its items, using will_paginate to bring back 50 items per page. When I output the items I want to display a number to indicate what item in the total collection it is. The numbering should be reversed as the collection is displayed with most recent first. This might not relate to will_paginate but rather some other method of calculation. I will be using the same ordering in multiple types so it will need to be reusable. As an example, say I have 51 movies. The first item of the first page should display: Fight Club - Watched: 30th Dec 2010 Whilst the last item on the page should display: The Matrix - Watched: 3rd Jan 2010 The paged collection is available as an instance variable e.g. @movies, and @movies.count will display the number of items in the paged collection. So if we're on page 1, movies.count == 50, whilst on page 2 @movies.count == 1. Using Movie.count would give 51. If the page number and page size can be accessed the number could be calculated so how can they be returned? Though I'm hopeful there is something that already exists to handle this calculation!

• JavaScript Show/Hide as Filters to list of divs

  - by deconspray

  Looking to create Javascript that acts like a filter on a list of divs. For instance, here's the intended markup... <a href="#" onclick="">Filter Item 1</a> <a href="#" onclick="">Filter Item 2</a> <a href="#" onclick="">Filter Item 3</a> <a href="#" onclick="">Filter Item 4</a> <a href="#" onclick="">Filter Item 5</a> <div class="1">Item 1</div> <div class="1">Item 1</div> <div class="2">Item 2</div> <div class="3">Item 3</div> <div class="1">Item 1</div> <div class="4">Item 4</div> <div class="4">Item 4</div> <div class="1">Item 1</div> <div class="5">Item 5</div> I want to be able to click on the link for Item 1, and show only Item 1 divs and hide all other divs, click the link of Item 2, and show only Item 2 divs and hide all other divs and so on. I've seen several similar scripts but nothing that seemingly turns divs matching the class on/off in this manner. TIA.
