  • Lighttpd Rewrites & Blank page

    - by Stathis
    Hello, I have configured some lighttpd rewrites, of which one does not work. This is the line that does not work as it should and causes a white (blank) page to be thrown: url.rewrite-once = ( ... "^/search/([^\/]+)*/([^\/]+)*/([0-9]+)$" => "search.php?t=$1&k=$2&p=$3", ... ); Also note that it is the only one with 3 parameters, all the rest in the section have 0-2. I found this error in the lighttpd error.log: 2011-01-07 17:13:09: (mod_rewrite.c.374) execution error while matching: -8 Can someone help? Thanks.

  • Decrementing/Incrementing loop variable inside for loop. Is this code smell?

    - by FairDune
    I have to read lines from a text file in sequential order. The file is a custom text format that contains sections. If some sections are out of order, I would like to look for the starting of the next valid section and continue processing. Currently, I have some code that looks like this: for (int currentLineIndex=0; currentLineIndex < lines.Count; currentLineIndex++ ) { //Process section here if( out_of_order_condition ) { currentLineIndex--;//Stay on the same line in the next iteration because this line may be the start of a valid section. continue; } } Is this code smell?

  • Pitfalls of using a WYSIWYG editor? [closed]

    - by user50849
    I'm interested in reasons for disallowing content editors on medium to large sites, from using various forms of WYSIWYG editors. A common problematic scenario I can think of is that with the use of a WYSIWYG, an editor uploads an image "somewhere" to the file-system, inserts it directly into the text, and publishes the article. Shortly afterwards, someone wants to pull out "The last 10 uploaded images", and display them on the frontpage. Good luck parsing all the content. Taking a look around at some large international online magazines, such as http://www.time.com/, and some local ones, I see that the editors seem to produce articles that are almost only consisting of raw text. Images are usually at the top of the article, and otherwise the most complex content are usually links. What are some common reasons for refusing editors access to WYSIWYG tools?

  • Problem with currency formats and big numbers [on hold]

    - by user132750
    I am working on a dollars to euros/euros to dollars converter in C#. I got the formula, $ times 0.73361 = euro, and I have checked Google with the answers. They were right, (1 dollar equals 0.73 euros). However, it stops working properly when the dollar input value is higher than $1363. This is what I get with $1364: $1364 = 1 000,64 €. I don't know what to do, will someone please help me? Thanks. decimal toEuro; Val.doy = "$" + decimal.Parse(richTextBox1.Text); //Ignore this, it's for the output form CultureInfo eu = new CultureInfo("fr-FR"); toEuro = decimal.Parse(richTextBox1.Text.Trim()); toEuro = toEuro * 0.73361m; richTextBox1.Clear(); Val.duh = toEuro.ToString("C2", eu);

  • Where do I read more about building an architecture like Google has? [on hold]

    - by user107148
    I want to develop a program that watches and traverses a rather big network for data. This data should then be available to search through with my program, maybe through a web interface or something. My intuitive thought at the moment is to build an architecture kind of like the one Google has. One "front-end" (the Google Search page) which is essentially a regular web application and one "back-end" (which in Google's case traverses the web). Now for the hard part: If I decide to make such a system, how should communication be done between these parts? One idea I had is to use some kind of database that both the back-end and front-end can access, but then comes the issues of concurrent writes and reads. Another issue with just using a database to communicate is that it makes it hard to "notify" the other part when something changes. Let's say that I want the "front-end" part to push changes to the UI when a change is noticed in the back-end. Then the back-end would have to have some way of notifying the front-end of this.

  • How can I move the Windows 7 Preview Pane to the bottom?

    - by Rich Bennema
    When searching for files in Windows Explorer, I like to use the Preview Pane to determine if it is the file I was looking for. But with the Preview Pane on the right hand side, either the preview is squished and unreadable or I need to make the Preview Pane wider which ends up hiding a lot of search information. Is there a way to move the Preview Pane to the bottom of the screen. I would rather see less lines in the preview and less files in the search results but be able to see (and read) all of what is being shown.

  • WHY Google does not ban these sites using this SEO pattern? [on hold]

    - by saddam.bg
    I have seen some sites using a different kind of SEO to promote copyrighted materials such as movies. They also have submitted their site to Google webmaster tools but still now did not get banned. Their Alexa ranks are 7000 or less. On the other hand I have run 5 movie affiliate sites and all of them got banned by Google within a short period of time. I have copied the url of the homepage of solarmovie.me and pasted it on the google search and instead of the homepage url I have seen that their category or tag shows as the homepage (www.solarmovie.me/watch-category/hollyw... Now is solarmovie.me publishing its posts as a single page or something else? I tried to find out what kind of SEO or coding that was, but I couldn't since I have very little knowledge about coding. Also I have seen the same thing with ALLUC.TO in google search (www.alluc.to/popular-links.html). Could anyone please help with the SEO of this kind so that I don't get banned by google frequently or index removed. All SEO webmaster i need your help!!!! Please give me some good tips for this type of SEO. Thank You Very Much

  • Creating a multi-tenant application using PostgreSQL's schemas and Rails

    - by ramon.tayag
    Stuff I've already figured out I'm learning how to create a multi-tenant application in Rails that serves data from different schemas based on what domain or subdomain is used to view the application. I already have a few concerns answered: How can you get subdomain-fu to work with domains as well? Here's someone that asked the same question which leads you to this blog. What database, and how will it be structured? Here's an excellent talk by Guy Naor, and good question about PostgreSQL and schemas. I already know my schemas will all have the same structure. They will differ in the data they hold. So, how can you run migrations for all schemas? Here's an answer. Those three points cover a lot of the general stuff I need to know. However, in the next steps I seem to have many ways of implementing things. I'm hoping that there's a better, easier way. Finally, to my question When a new user signs up, I can easily create the schema. However, what would be the best and easiest way to load the structure that the rest of the schemas already have? Here are some questions/scenarios that might give you a better idea. Should I pass it on to a shell script that dumps the public schema into a temporary one, and imports it back to my main database (pretty much like what Guy Naor says in his video)? Here's a quick summary/script I got from the helpful #postgres on freenode. While this will probably work, I'm gonna have to do a lot of stuff outside of Rails, which makes me a bit uncomfortable.. which also brings me to the next question. Is there a way to do this straight from Ruby on Rails? Like create a PostgreSQL schema, then just load the Rails database schema (schema.rb - I know, it's confusing) into that PostgreSQL schema. Is there a gem/plugin that has these things already? Methods like "create_pg_schema_and_load_rails_schema(the_new_schema_name)". If there's none, I'll probably work at making one, but I'm doubtful about how well tested it'll be with all the moving parts (especially if I end up using a shell script to create and manage new PostgreSQL schemas). Thanks, and I hope that wasn't too long! UPDATE May 11, 2010 11:26 GMT+8 Since last night I've been able to get a method to work that creates a new schema and loads schema.rb into it. Not sure if what I'm doing is correct (seems to work fine, so far) but it's a step closer at least. If there's a better way please let me know. module SchemaUtils def self.add_schema_to_path(schema) conn = ActiveRecord::Base.connection conn.execute "SET search_path TO #{schema}, #{conn.schema_search_path}" end def self.reset_search_path conn = ActiveRecord::Base.connection conn.execute "SET search_path TO #{conn.schema_search_path}" end def self.create_and_migrate_schema(schema_name) conn = ActiveRecord::Base.connection schemas = conn.select_values("select * from pg_namespace where nspname != 'information_schema' AND nspname NOT LIKE 'pg%'") if schemas.include?(schema_name) tables = conn.tables Rails.logger.info "#{schema_name} exists already with these tables #{tables.inspect}" else Rails.logger.info "About to create #{schema_name}" conn.execute "create schema #{schema_name}" end # Save the old search path so we can set it back at the end of this method old_search_path = conn.schema_search_path # Tried to set the search path like in the methods above (from Guy Naor) # conn.execute "SET search_path TO #{schema_name}" # But the connection itself seems to remember the old search path. # If set this way, it works. conn.schema_search_path = schema_name # Directly from databases.rake. # In Rails 2.3.5 databases.rake can be found in railties/lib/tasks/databases.rake file = "#{Rails.root}/db/schema.rb" if File.exists?(file) Rails.logger.info "About to load the schema #{file}" load(file) else abort %{#{file} doesn't exist yet. It's possible that you just ran a migration!} end Rails.logger.info "About to set search path back to #{old_search_path}." conn.schema_search_path = old_search_path end end

  • WPF Styles and Tooltips Question

    - by A.R.
    I have a style that I am using to make dynamic tooltips on certain text boxes like so. <Style TargetType="{x:Type TextBox}"> <Setter Property="MinWidth" Value="100"/> <Style.Triggers> <Trigger Property="Validation.HasError" Value="True"> <!-- item of interest --> <Setter Property="ToolTip"> <Setter.Value> <MultiBinding Converter="{StaticResource ErrorMessageConverter}"> <Binding RelativeSource="{RelativeSource Self}" Path="Tag"/> </MultiBinding> </Setter.Value> </Setter> </Trigger> </Style.Triggers> </Style> This works very well, but if I want to use a more complex tooltip I can't figure out how to bind to 'Tag' anymore for the converter value. For example; ... <Setter Property="ToolTip"> <Setter.Value> <StackPanel> <TextBlock> <TextBlock.Text> <MultiBinding Converter="{StaticResource ErrorMessageConverter}"> <!-- item of interest --> <Binding RelativeSource=" what goes here?? "/> </MultiBinding> </TextBlock.Text> </TextBlock> <Image/> </StackPanel> </Setter.Value> </Setter> ... I have tried several flavors of 'FindAncestor' and what not for the relative source, but I can't get anything to work. Any ideas?? UPDATE: 12-29-2010 : Here is the correct code, answer provided by our friend Goblin below. Works perfectly! ... <Setter Property="ToolTip"> <Setter.Value> <!-- Item of interest --> <ToolTip DataContext="{Binding Path=PlacementTarget, RelativeSource={x:Static RelativeSource.Self}}"> <StackPanel> <Image/> <TextBlock> <TextBlock.Text> <MultiBinding Converter="{StaticResource ErrorMessageConverter}"> <Binding Path="Tag"/> </MultiBinding> </TextBlock.Text> </TextBlock> </StackPanel> </ToolTip> </Setter.Value> </Setter> ...

  • How can I dynamically change auto complete entries in a C# combobox or textbox?

    - by Sam Hopkins
    I have a combobox in C# and I want to use auto complete suggestions with it, however I want to be able to change the auto complete entries as the user types, because the possible valid entries are far too numerous to populate the AutoCompleteStringCollection at startup. As an example, suppose I'm letting the user type in a name. I have a list of possible first names ("Joe", "John") and a list of surnames ("Bloggs", "Smith"), but if I have a thousand of each, then that would be a million possible strings - too many to put in the auto complete entries. So initially I want to have just the first names as suggestions ("Joe", "John") , and then once the user has typed the first name, ("Joe"), I want to remove the existing auto complete entries and replace them with a new set consisting of the chosen first name followed by the possible surnames ("Joe Bloggs", "Joe Smith"). In order to do this, I tried the following code: void InitializeComboBox() { ComboName.AutoCompleteMode = AutoCompleteMode.SuggestAppend; ComboName.AutoCompleteSource = AutoCompleteSource.CustomSource; ComboName.AutoCompleteCustomSource = new AutoCompleteStringCollection(); ComboName.TextChanged += new EventHandler( ComboName_TextChanged ); } void ComboName_TextChanged( object sender, EventArgs e ) { string text = this.ComboName.Text; string[] suggestions = GetNameSuggestions( text ); this.ComboQuery.AutoCompleteCustomSource.Clear(); this.ComboQuery.AutoCompleteCustomSource.AddRange( suggestions ); } However, this does not work properly. It seems that the call to Clear() causes the auto complete mechanism to "turn off" until the next character appears in the combo box, but of course when the next character appears the above code calls Clear() again, so the user never actually sees the auto complete functionality. It also causes the entire contents of the combo box to become selected, so between every keypress you have to deselect the existing text, which makes it unusable. If I remove the call to Clear() then the auto complete works, but it seems that then the AddRange() call has no effect, because the new suggestions that I add do not appear in the auto complete dropdown. I have been searching for a solution to this, and seen various things suggested, but I cannot get any of them to work - either the auto complete functionality appears disabled, or new strings do not appear. Here is a list of things I have tried: Calling BeginUpdate() before changing the strings and EndUpdate() afterwards. Calling Remove() on all the existing strings instead of Clear(). Clearing the text from the combobox while I update the strings, and adding it back afterwards. Setting the AutoCompleteMode to "None" while I change the strings, and setting it back to "SuggestAppend" afterwards. Hooking the TextUpdate or KeyPress event instead of TextChanged. Replacing the existing AutoCompleteCustomSource with a new AutoCompleteStringCollection each time. None of these helped, even in various combinations. Spence suggested that I try overriding the ComboBox function that gets the list of strings to use in auto complete. Using a reflector I found a couple of methods in the ComboBox class that look promising - GetStringsForAutoComplete() and SetAutoComplete(), but they are both private so I can't access them from a derived class. I couldn't take that any further. I tried replacing the ComboBox with a TextBox, because the auto complete interface is the same, and I found that the behaviour is slightly different. With the TextBox it appears to work better, in that the Append part of the auto complete works properly, but the Suggest part doesn't - the suggestion box briefly flashes to life but then immediately disappears. So I thought "Okay, I'll

  • Treeview - Hierarchical Data Template - Binding does not update on source change?

    - by ClearsTheScreen
    Greetings! I ran into this problem in my project (Silverlight 3 with C#): I have a TreeView which is data bound to, well, a tree. This TreeView has a HierarchicalDataTamplate in a resource dictionary, that defines various controls. Now I want to hide (Visibility.Collapse) some items depending on wether a node has children or not. Other items shall be visible under the same condition. It works like charm when I first bind the source tree to the TreeView, but when I change the source tree, the visibility in the treeview does not change. XAML - page: <controls:TreeView x:Name="SankeyTreeView" ItemContainerStyle="{StaticResource expandedTreeViewItemStyle}" ItemTemplate="{StaticResource SankeyTreeTemplate}"> <controls:TreeViewItem IsExpanded="True"> <controls:TreeViewItem.HeaderTemplate> <DataTemplate> <TextBlock Text="This is just for loading and will be replaced directly after the data becomes available..."/> </DataTemplate> </controls:TreeViewItem.HeaderTemplate> </controls:TreeViewItem> </controls:TreeView> XAML - ResourceDictionary <!-- Each node in the tree is structurally identical, hence only one Hierarchical Data Template that'll use itself on the children. --> <Data:HierarchicalDataTemplate x:Key="SankeyTreeTemplate" ItemsSource="{Binding Children}"> <Grid Height="24"> <TextBlock x:Name="TextBlockName" Text="{Binding Path=Value.name, Mode=TwoWay}" VerticalAlignment="Center" Foreground="Black"/> <TextBox x:Name="TextBoxFlow" Text="{Binding Path=Value.flow, Mode=TwoWay}" Grid.Column="1" Visibility="{Binding Children, Converter={StaticResource BoxConverter}, ConverterParameter=\{box\}}"/> <TextBlock x:Name="TextBlockThroughput" Text="{Binding Path=Value.throughput, Mode=TwoWay}" Grid.Column="1" Visibility="{Binding Children, Converter={StaticResource BoxConverter}, ConverterParameter=\{block\}}"/> <Button x:Name="ButtonAddNode"/> <Button x:Name="ButtonDeleteNode"/> <Button x:Name="ButtonEditNode"/> </Grid> </Data:HierarchicalDataTemplate> Now, as you can see, the TextBoxFlow and the TextBlockThroughput share the same space. What I aim at: The "Throughput" value of a node is how much of something 'flows' through this node from its children. It can't be changed directly, so I want to display a text block. Only leaf nodes have a TextBox to let someone enter the 'flow' that is generated in this leaf node. (I.E.: Node.Throughput = Node.Flow + Sum(Children.Throughput), where Node.Flow = 0 for each non-leaf.) What the BoxConverter (silly name -.-) does: public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { if ((value as NodeList<TreeItem>).Count > 1) // Node has Children? { if ((parameter as String) == "{box}") { return Visibility.Collapsed; } else ((parameter as String) == "{block}") { return Visibility.Visible; } } else { /* * As above, just with Collapsed and Visible switched */ } } The structure of the tree that is bound to the TreeView is essentially stolen from Dan Vanderboom (a bit too much to dump the whole code here), except that I here of course use an ObservableCollection for the children and the value items implement INotifyPropertyChanged. I would be very grateful if someone could explain to me, why inserting items into the underlying tree does not update the visibility for box and block. Thank you in advance!

  • Drawing a WPF UserControl with DataBinding to an Image

    - by LorenVS
    Hey Everyone, So I'm trying to use a WPF User Control to generate a ton of images from a dataset where each item in the dataset would produce an image... I'm hoping I can set it up in such a way that I can use WPF databinding, and for each item in the dataset, create an instance of my user control, set the dependency property that corresponds to my data item, and then draw the user control to an image, but I'm having problems getting it all working (not sure whether databinding or drawing to the image is my problem) Sorry for the massive code dump, but I've been trying to get this working for a couple of hours now, and WPF just doesn't like me (have to learn at some point though...) My User Control looks like this: <UserControl x:Class="Bleargh.ImageTemplate" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:c="clr-namespace:Bleargh" x:Name="ImageTemplateContainer" Height="300" Width="300"> <Canvas> <TextBlock Canvas.Left="50" Canvas.Top="50" Width="200" Height="25" FontSize="16" FontFamily="Calibri" Text="{Binding Path=Booking.Customer,ElementName=ImageTemplateContainer}" /> <TextBlock Canvas.Left="50" Canvas.Top="100" Width="200" Height="25" FontSize="16" FontFamily="Calibri" Text="{Binding Path=Booking.Location,ElementName=ImageTemplateContainer}" /> <TextBlock Canvas.Left="50" Canvas.Top="150" Width="200" Height="25" FontSize="16" FontFamily="Calibri" Text="{Binding Path=Booking.ItemNumber,ElementName=ImageTemplateContainer}" /> <TextBlock Canvas.Left="50" Canvas.Top="200" Width="200" Height="25" FontSize="16" FontFamily="Calibri" Text="{Binding Path=Booking.Description,ElementName=ImageTemplateContainer}" /> </Canvas> </UserControl> And I've added a dependency property of type "Booking" to my user control that I'm hoping will be the source for the databound values: public partial class ImageTemplate : UserControl { public static readonly DependencyProperty BookingProperty = DependencyProperty.Register("Booking", typeof(Booking), typeof(ImageTemplate)); public Booking Booking { get { return (Booking)GetValue(BookingProperty); } set { SetValue(BookingProperty, value); } } public ImageTemplate() { InitializeComponent(); } } And I'm using the following code to render the control: List<Booking> bookings = Booking.GetSome(); for(int i = 0; i < bookings.Count; i++) { ImageTemplate template = new ImageTemplate(); template.Booking = bookings[i]; RenderTargetBitmap bitmap = new RenderTargetBitmap( (int)template.Width, (int)template.Height, 120.0, 120.0, PixelFormats.Pbgra32); bitmap.Render(template); BitmapEncoder encoder = new PngBitmapEncoder(); encoder.Frames.Add(BitmapFrame.Create(bitmap)); using (Stream s = File.OpenWrite(@"C:\Code\Bleargh\RawImages\" + i.ToString() + ".png")) { encoder.Save(s); } } EDIT: I should add that the process works without any errors whatsoever, but I end up with a directory full of plain-white images, not text or anything... And I have confirmed using the debugger that my Booking objects are being filled with the proper data... EDIT 2: Did something I should have done a long time ago, set a background on my canvas, but that didn't change the output image at all, so my problem is most definitely somehow to do with my drawing code (although there may be something wrong with my databinding too)

  • How to configure a GridView CommandField to trigger Full Page Update in UpdatePanel

    - by Frinavale
    I have 2 user controls on my page. One is used for searching, and the other is used for editing (along with a few other things). The user control that provides the search functionality uses a GridView to display the search results. This GridView has a CommandField used for editing (showEditButton="true"). I would like to place the GridView into an UpdatePanel so that paging through the search results will be smooth. The thing is that when the user clicks the Edit Link (the CommandField) I need to preform a full page postback so that the search user control can be hidden and the edit user control can be displayed. Edit: the reason I need to do a full page postback is because the edit user control is outside of the UpdatePanel that my GridView is in. It is not only outside the UpdatePanel, but it's in a completely different user control. I have no idea how to add the CommandField as a full page postback trigger to the UpdatePanel. The PostBackTrigger (which is used to indicate the controls cause a full page postback) takes a ControlID as a parameter; however the CommandButton does not have an ID...and you can see why I'm having a problem with this. Update on what else I've tried to solve the problem: I took a new approach to solving the problem. In my new approach, I used a TemplateField instead of a CommandField. I placed a LinkButton control in the TemplateField and gave it a name. During the GridView's RowDataBound event I retrieved the LinkButton control and added it to the UpdatePanel's Triggers. This is the ASP Markup for the UpdatePanel and the GridView <asp:UpdatePanel ID="SearchResultsUpdateSection" runat="server"> <ContentTemplate> <asp:GridView ID="SearchResultsGrid" runat="server" AllowPaging="true" AutoGenerateColumns="false"> <Columns> <asp:TemplateField> <HeaderTemplate></HeaderTemplate> <ItemTemplate> <asp:LinkButton ID="Edit" runat="server" Text="Edit"></asp:LinkButton> </ItemTemplate> </asp:TemplateField> <asp:BoundField ...... </Columns> </asp:GridView> </ContentTemplate> </asp:UpdatePanel> In my VB.NET code. I implemented a function that handles the GridView's RowDataBound event. In this method I find the LinkButton for the row being bound to, create a PostBackTrigger for the LinkButton, and add it to the UpdatePanel's Triggers. This means that a PostBackTrigger is created for every "edit" LinkButton in the GridView Edit: this did not create a PostBackTrigger for Every "edit" LinkButton because the ID is the same for all LinkButtons in the GridView. Private Sub SearchResultsGrid_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles SearchResultsGrod.RowDataBound If e.Row.RowType = DataControlRowType.Header Then ''I am doing stuff here that does not pertain to the problem Else Dim editLink As LinkButton = CType(e.Row.FindControl("Edit"), LinkButton) If editLink IsNot Nothing Then Dim fullPageTrigger As New PostBackTrigger fullPageTrigger.ControlID = editLink.ID SearchResultsUpdateSection.Triggers.Add(fullPageTrigger) End If End If End Sub And instead of handling the GridView's RowEditing event for editing purposes i use the RowCommand instead. Private Sub SearchResultsGrid_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles SearchResultsGrid.RowCommand RaiseEvent EditRecord(Me, New EventArgs()) End Sub This new approach didn't work at all because all of the LinkButtons in the GridView have the same ID. After reading the MSDN article on the UpdatePanel.Triggers Property I have the impression that Triggers can only be defined declaratively. This would mean that anything I did in the VB code wouldn't work. Any advise would be greatly appreciated. Thanks, -Frinny

  • FBML is not rendered in Facebook App in iframe - please help

    - by Jakob
    I'm developing an Facebook Application in PHP. It's loaded as an iframe and not as FBML. The normal interaction with Facebook works. For example the following code gives the username: $facebook = new Facebook($config->appapikey, $config->appsecret); $user_id = $facebook->require_login($required_permissions = 'email'); echo $user->name; Where $user is my class in which the user-details are loaded from facebook. My document begins the following way: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml"> <head><title>Appname</title> </head> <body> <script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php/de_DE" type="text/javascript"></script> And ends likes this: <script type="text/javascript"> FB_RequireFeatures(['XFBML','CanvasUtil'], function(){ FB.init("<?php echo $config->appapikey; ?>", "/app/xd_receiver.htm"); FB.CanvasClient.startTimerToSizeToContent(); }); </script> </body> </html> Also the file xd_receiver.htm is loaded as I can see in Firebug. But my problem is that for example the request-form is not loaded. My code: <fb:serverFbml> <script type="text/fbml"> <fb:fbml> <fb:request-form method="post" action="<?php echo $config->site; ?>index.php" type="appname" invite="true" target="_top" content="content"> <fb:multi-friend-selector actiontext="text" rows="3" showborder="true" target="_top"/> </fb:request-form> </fb:fbml> </script> </fb:serverFbml> I can see the code with Firebug but the form ist not displayed by Facebook. 2 or 3 weeks ago it was displayed but in this time I had the tags </fb:fbml> </script> </fb:serverFbml> arround my complete text in the body. 2 weeks ago I had the the problem that nothing any more was displayed. After I removed the tags my app is displayed but not the form. I am searchign the web vor 1 week now and read many Threads about FBML and XFBML in Facebook but nothing worked for me. So thank you in advance for help.

  • Fetching data (responsebody) with a HttpClient in an AsyncTask and returning the data outside the As

    - by Peter Warbo
    Basically I'm wondering how I'm able to do what I've written in the topic. I've looked through many tutorials on AsyncTask but I can't get it to work. I have a little form (EditText) that will take what the user inputs there and make it to a url query for the application to lookup and then display the results. What I think would seem to work is something like this: In my main activity i have a string called responseBody. Then the user clicks on the search button it will go to my search function and from there call the GrabUrl method with the url which will start the asyncdata and when that process is finished the onPostExecute method will use the function activity.this.setResponseBody(content). This is what my code looks like simpliefied with the most important parts (I think). public class activity extends Activity { private String responseBody; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); initControls(); } public void initControls() { fieldSearch = (EditText) findViewById(R.id.EditText01); buttonSearch = (Button)findViewById(R.id.Button01); buttonSearch.setOnClickListener(new Button.OnClickListener() { public void onClick (View v){ search(); }}); } public void grabURL(String url) { new GrabURL().execute(url); } private class GrabURL extends AsyncTask<String, Void, String> { private final HttpClient client = new DefaultHttpClient(); private String content; private boolean error = false; private ProgressDialog dialog = new ProgressDialog(activity.this); protected void onPreExecute() { dialog.setMessage("Getting your data... Please wait..."); dialog.show(); } protected String doInBackground(String... urls) { try { HttpGet httpget = new HttpGet(urls[0]); ResponseHandler<String> responseHandler = new BasicResponseHandler(); content = client.execute(httpget, responseHandler); } catch (ClientProtocolException e) { error = true; cancel(true); } catch (IOException e) { error = true; cancel(true); } return content; } protected void onPostExecute(String content) { dialog.dismiss(); if (error) { Toast toast = Toast.makeText(activity.this, getString(R.string.offline), Toast.LENGTH_LONG); toast.setGravity(Gravity.TOP, 0, 75); toast.show(); } else { activity.this.setResponseBody(content); } } } public void search() { String query = fieldSearch.getText().toString(); String url = "http://example.com/example.php?query=" + query; //this is just an example url, I have a "real" url in my application but for privacy reasons I've replaced it grabURL(url); // the method that will start the asynctask processData(responseBody); // process the responseBody and display stuff on the ui-thread with the data that I would like to get from the asyntask but doesn't obviously }
