  • Does Ruby have a special stack for returning a value?

    - by prosseek
    The following Ruby code def a(b,c) b+c end is the same as follows with Python def a(b,c): return b+c It looks like that ruby has the special stack that stores the final evaluation result and returns the value when a function is called. If so, what's the name of the stack, and how can I get that stack? If not, how does the Ruby code work without returning something?

  • observing multiple select menus with prototype

    - by snaken
    Hi, I want to observe multiple select menus and respond to their changes using prototype but only the first menu seems to be observed. This is my code: $('product_options').select('select').invoke("observe","change",optchange); If there are - for example - 3 selects within product_options then it only observes the first, i thought it might be because of invoke so i then tried this: $('product_options').select('select').each(function(sel){ $(sel).observe("change",optchange); }); Still doesnt work though, any ideas whats wrong?

  • Android runs OpenGL ES 1.1 or 1.0?

    - by cjserio
    I'm developing a native app for Android and I'm trying to use functions such as glIsEnabled which appear to be only available in OpenGL ES 1.1. Google's docs claim that NDK 1.6R1 supports OpenGL ES v1.1 but the function call fails with "unimplemented Open GL ES API" and if i do a glGetString(GL_VERSION) it returns "OpenGL ES 1.0 CM" as the version. So if 1.1 is available, what do I have to link against to get it or what else do i need to change to get it?

  • Drupal menu permissions question

    - by Luke
    I'm creating an admin module for my client that gives then access to some administration functionality concerning their content. I'm starting off my adding some permissions in my module by implementing hook_perm: function mymodule_perm() { return array( 'manage projects', ); } I can then create my menu by adding to the admin section that already exists: function mymodule_menu() { $items['admin/projects'] = array( 'title' => 'Projects', 'description' => 'Manage your projects.', 'page callback' => 'manage_projects_overview', 'access callback' => 'user_access', 'access arguments' => array('manage projects'), 'type' => MENU_NORMAL_ITEM, 'weight' => -100, ); $items['admin/projects/add'] = array( 'title' => 'Add project', 'access arguments' => array('manage projects'), 'page callback' => 'mymodule_projects_add', 'type' => MENU_NORMAL_ITEM, 'weight' => 1, ); return $items; } This will add a Projects section to the Administration area with an Add project sub section. All good. The behavior I want is that my client can only see the Projects section when they log in. I've accomplished this by ticking the "manage projects" permission for authenticated users. Now to give my client actual access to the Administration area I also need to tick "access administration pages" under the "system module" in the users permissions section. This works great, when I log in as my client I can only see the Projects section in the Administration area. There is one thing though, I my Navigation menu shown in the left column I can see the following items: - Administer - Projects - Content management - Site building - Site configuration - User management I was expecting only the see Administer and Projects, not the other ones. When I click e.g. Content Management I get a Content Management titled page with no options. Same for Site Building, Site Configuration and User Management. What's really odd is that Reports is not being shown which is also a top level Administration section. Why are these other items, besides my Projects section, being shown and how can I make them stop from appearing if I'm not logged in as administrator?

  • JQuery not copying state dropdown list 1 to DDL2 on checkbox change

    - by user1001411
    I've looked at similar posts on the subject but none of the recommended solutions have worked for me so I'm not sure where I'm going wrong. I have a billing and shipping address form with a dropdown list for the state. Upon checking/unchecking the "billing address same as shipping" everything copies over except the state dropdown list. The state dropdown list is populated from a SQLDataSource state table. Here's my code: <script type="text/javascript" language="javascript" src="../Scripts/jquery-1.4.1.min.js"></script> <script type="text/javascript"> $(document).ready(function () { $('input:checkbox[id*=chkCopy]').change(function () { if ($(this).is(':checked')) { $('input:text[id*=TextBox5]').val($('input:text[id*=TextBox1]').val()); $('input:text[id*=TextBox7]').val($('input:text[id*=TextBox2]').val()); $('input:text[id*=TextBox9]').val($('input:text[id*=TextBox3]').val()); $('input:text[id*=TextBox12]').val($('input:text[id*=TextBox4]').val()); $('select#DropDownList6').val($("select#DropDownList1").val()); $('input:text[id*=TextBox14]').val($('input:text[id*=TextBox6]').val()); } else { $('input:text[id*=TextBox5]').val(''); $('input:text[id*=TextBox7]').val(''); $('input:text[id*=TextBox9]').val(''); $('input:text[id*=TextBox12]').val(''); $('select#DropDownList6').val(''); $('input:text[id*=TextBox14]').val(''); } }); }); and here is my SQL for the DDL: <asp:DropDownList ID="DropDownList1" runat="server" DataTextField="Descr" DataValueField="ID" DataSourceID="SqlDataSource1" Width="254"> </asp:DropDownList> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ASPNETDBConnectionString1 %>" SelectCommand="SELECT * FROM [xrefState]"> </asp:SqlDataSource> the other one: <asp:DropDownList ID="DropDownList6" runat="server" DataTextField="Descr" DataValueField="ID" DataSourceID="SqlDataSource5" Width="254"> </asp:DropDownList> <asp:SqlDataSource ID="SqlDataSource5" runat="server" ConnectionString="<%$ ConnectionStrings:ASPNETDBConnectionString1 %>" SelectCommand="SELECT * FROM [xrefState]"> </asp:SqlDataSource>

How do I convert the string to a node so that the method will accept the string.

  • Javascript: move the "view point" of the browser

    - by ArchJ
    I have a page with many out-of-bounds contents and since I set body{overflow:hidden}, they are not outside the viewport. So I want to attach a function to a button which would move the PoV of the browser so that the out-of-bounds contents would come into the viewport. What I can think of now is to set body{position:relative} and use jQuery to animate() the body instead. But in terms of performance, is there a better way to achieve that?
