    This code compiles in CodeGear 2009 and Visual Studio 2010 but not gcc. Why? class Foo { public: operator int() const; template <typename T> T get() const { return this->operator T(); } }; Foo::operator int() const { return 5; } The error message is: test.cpp: In member function `T Foo::get() const': test.cpp:6: error: 'const class Foo' has no member named 'operator T'

  • Grouped items in Table view like the Mail app on the iPad

    - by happyCoding25
    Hello, I'm trying to figure out how to group items like the grouped mail boxes in the mail app. I need it to be like selecting a mail box, when you tap it it loads new data, your inbox outbox and all of the other boxes for that mail account. Then you can tap back and return to all of your accounts. If anyone has a little sample code they could show or explain how one might go about doing this any help is appreciated. (Note: Im using the split view template) Thanks

  • Drupal: assign block to a specific content type

    - by bert
    I made a customized template called node-mynode.tpl.php Whenever a node of type mynode is requested, then node-mynode.tpl.php is automatically used. However, now user wants to see a specific menu block in this case. Question: How can I assign a block to a specific content type? Hint: I have started to look at URL aliases with Pathauto. I suspect one solution may lie in this direction.

  • Using jQuery's ajax get request with parameters, returning page content

    - by Stevie Jenowski
    Thank you for looking at my question, as I appreciate your time. Okay, so I'm trying to use jQuery's get function to call my php script which ultimately returns a variable which is a built template of the main content of my page minus my static header/footer, for which I would like to replace the "old" page content without the page reloading. Can anyone point me in the right direction as to where I'm going wrong here? My code is as follows... jQuery: function getData(time, type) { $.ajax({ type: "GET", url: "getData.php", data: "time=" + time + "&type=" + type, success: function(data){ $('#pageContent').fadeOut("slow"); $('#pageContent').html(data); $('#pageContent').fadeIn("slow"); } }); return false; } getData.php(paraphrased): .... $time = empty($_GET['time']) ? '' : $_GET['time']; $type = empty($_GET['type']) ? '' : $_GET['type']; echo getData($time, $type); function getData($time, $type) ...... ..... $tmpl = new Template(); $tmpl->time= $time; $tmpl->type = $type; $builtpage = $tmpl->build('index.tmpl'); return $builtpage; ..... ...... jQuery function call: <a href="#" onclick="getData("<?php print $tmpl->time; ?>", "Orange")">Orange</a> <a href="#" onclick="getData("<?php print $tmpl->time; ?>", "Apple")">Apple</a> <a href="#" onclick="getData("<?php print $tmpl->time; ?>", "Banana")">Banana</a> When I click any link, the ajax seems to run fine, and the page does refuse to reload, but the content still remains unchanged... Anyone happen to know what's up?

  • Xcode C++ debugging

    - by mousebird
    I'm looking for a way to have the Xcode IDE pick up on the contents of my weird Boost template classes. Basically, classes complex enough that Xcode can't display their contents correctly. Is there something like the Objective C -description method or toString() in Java that Xcode will look for? At the moment I'm just implementing print() methods and invoking them in gdb, but that's likely to confuse other developers.

  • Pros and cons of escaping strategies in symfony

    - by zergu
    I am still not sure in that matter. While turned on we're quite safe but some other problems appear (with passing template variables or counting characters). On the other hand we have magic turned off, everything is clear, but we have to manually escape every variable (that come from untrusted source) in templates. By the way, non-magic solution is used in Ruby-on-Rails. So the question is: when starting a new project in symfony do you disable escaping_strategy and why?

  • dynamic Grid columns

    - by stck777
    Hi, I need help with dynamic columns in a DataGrid. I use GenericFrame front-end with PHP backend. If I use static columns like this: <? ... ?> <DataGrid id="DataGrid1" width="100%"> <columns> <DataGridColumn headerText="name" dataField="@username" width="150"/> <DataGridColumn headerText="Nahcname" dataField="@secondname" width="150"/> <DataGridColumn headerText="alter" dataField="@age" width="40"/> </columns> </DataGrid> <? ... ?> It is working fine. But I try to create the columns dynamic with PHP. <generic> <template target="gridbox"> <VBox id="dynamic" height="100%"> <!-- DataGrid --> <DataGrid id="DataGrid1" width="100%" > <columns> <?php $columns = array( //Spalte => (Breite, Datenfeld) "name" => array(150,"@username"), "Nahcname" => array(150,"@secondname"), "alter"=> array(40,"@age") ); foreach ($columns as $key => $value) { ?> <DataGridColumn headerText="<? echo $key; ?>" dataField="<? echo $value[0]; ?>" width="<? echo $value[0];?>"/> <?php } ?> </columns> </DataGrid> <Binding source="templatedata.data1.item" destination="DataGrid1.dataProvider" /> </VBox> </template> <templatedata> <data1> <!-- Daten --> <item username="User1" secondname="Nachname1" age="22"/> <item username="User2" secondname="Nachname2" age="25"/> <item username="User3" secondname="Nachname3" age="27"/> <item username="User4" secondname="Nachname4" age="32"/> </data1> </templatedata> The DataGrid is displayed correctly, but without data? any idea why?

  • Create java sandbox based on security policies

    - by argos
    I need to create environment to run potentially untrusted code. Program allowed to connect to preconfigured address:port and nothing else (even read the system time). I have compiled the class whitelist. I'd searched similar questions, but found only template that based on SecurityManager which AFAIK is deprecated. Can anybody give me a simple sample how to run code in sandbox based on security policies and AccessController?

  • Modifying wordpress plugin markup

    - by D L
    Is there a 'good working practise' way to modify the markup that a wordpress plugin produces without editing the plugin's core files. The problem i foresee is that when you update the plugin, the markup that you would have modified overwritten. I know in drupal there are template overrides, but i don't know enough about wordpress to do a similar practise. Any help?

  • Interpolation not working on Rails generator

    - by Tom
    For some reason the code I have included below does not interpolate the variables into the template. It simply copies the file over verbatim. I cannot figure out why. https://gist.github.com/60484f7b57b06b6eb3e3 The Rails version is 2.3.4. Thanks in advance!

  • GridView's ItemContainerStyle and selection states

    - by Roberto Casadei
    I'm trying to change the appearance of gridview items when they are selected. (Before, I used a trick with an IsSelected property in the ViewModel object bound to the containing grid and a bool-to-color converter, but I recognize that it is bad) To do so, I do: <GridView ItemContainerStyle="{StaticResource GridViewItemContainerStyle}" ...> ... and <Style x:Key="GridViewItemContainerStyle" TargetType="GridViewItem"> <Setter Property="Background" Value="Red" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="GridViewItem"> <Grid> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="CommonStates"> <VisualState x:Name="Normal"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(Grid.Background)" Storyboard.TargetName="itemGrid"> <DiscreteObjectKeyFrame KeyTime="0" Value="Black"/> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> </VisualStateGroup> <VisualStateGroup x:Name="SelectionStates"> <VisualState x:Name="UnselectedSwiping"/> <VisualState x:Name="UnselectedPointerOver"/> <VisualState x:Name="Selecting"/> <VisualState x:Name="Selected"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(Grid.Background)" Storyboard.TargetName="itemGrid"> <DiscreteObjectKeyFrame KeyTime="0" Value="White"/> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> <VisualState x:Name="SelectedSwiping"/> <VisualState x:Name="Unselecting"/> <VisualState x:Name="Unselected"/> <VisualState x:Name="SelectedUnfocused"/> </VisualStateGroup> </VisualStateManager.VisualStateGroups> <Grid ... x:Name="itemGrid"> <!-- HERE MY DATA TEMPLATE --> </Grid> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> When I run the app, the items are Black (as in the "normal" state). But selecting them does not turn them into White. Where am I wrong? Moreover, it there a way to set "ItemContainerStyle" without having it to "overwrite" the "ItemTemplate" ???

There is a javascript being rendered on the resulting HTML page that requires a strict doctype in order to work across all browsers. However, I cant get the doctype to show up. Any thoughts on this? Would it be possible to insert it dynamically, using javascript or php? Any help is appreciated.

  • What are possible designs for the DCI architecture?

    - by Gabriel Šcerbák
    What are possibles designs for implementation of the DCI (data, contexts, interactions) architecture in different OOP languages? I thought of Policy based design (Andrei Alexandrescu) for C++, DI and AOP for Java. However, I also thought about using State design pattern for representing roles and some sort of Template method for the interactions... What are the other possibilities?
