• Creating a row of Three Boxes Seperated

  - by Frank G.

  I am new to css and I have a menu bar that I am working on however I am having a problem with one of the menu ("LINKS") items. If you roll over the Links menu item your notice I have three boxes there that I am trying to separate into there own area. Right now they are over lapping each other. Could you please tell me what I am doing wrong? I have tried margin-left and padding-left and I find that they either move the box further to the right or widen the box more. But they don't space them out. You can find the menu bar here: http://jsfiddle.net/vtjPR/

• Java Wicket - Calling javascript ( JQuery ) before AJAX

  - by user1428051

  I got this thing i'm trying to solve: I got a ListView created using Wicket ( 1.5 ) with a lot of elements and a scroll. When new items are available, the user is asked if he would like to refresh the list via a message backed by an AjaxLink: public void onClick(AjaxRequestTarget ajaxTarget) { /* do something ... */ ajaxTarget.addComponent(_list); } So on click the list gets reloaded and the scroll position is reset to zero. Is there any way i can call JavaScript before the list reloads the save the scroll position? (I know how to get/save the scroll position ( .scrollTop() ) , i just don't know how to call a function right before AJAX ).

• Please help me get my content div to get an auto height from absolutely positioned element

  - by Justin Hollender

  I need some help with a CSS layout. It is set up like this: +--------------------+ | | | header | |-| |--------------| | |nav| content | | | | | | | | | | | | | | footer | +--------------------+ So, the nav is supposed to be floating above all the main page content. That's why I have it set to be absolutely positioned. The issue is that the nav items are dynamic, without a set height. Right now, the nav expands past the content. How can I fix it so that the content will have an auto height based off the nav? Thanks in advance.

• Birthday effect - clarification needed plz.

  - by Mark

  Please help interpret the Birthday effect as described in Wikipedia: A birthday attack works as follows: 1) Pick any message m and compute h(m). 2) Update list L. Check if h(m) is in the list L. 3) if (h(m),m) is already in L, a colliding message pair has been found. else save the pair (h(m),m) in the list L and go back to step 1. From the birthday paradox we know that we can expect to find a matching entry, after performing about 2^(n/2) hash evaluations. Does the above mean 2^(n/2) iterations through the above entire loop (i.e. 2^(n/2) returns to step 1), OR does it mean 2^(n/2) comparisons to individual items already in L.

  How can I call the button1_Click event in the form closing event so I don't have to copy and paste the code from button1_Click? public void button1_Click(object sender, EventArgs e) { //Yes or no message box to exit the application DialogResult Response; Response = MessageBox.Show("Are you sure you want to Exit?", "Exit", MessageBoxButtons.YesNo, MessageBoxIcon.Question, MessageBoxDefaultButton.Button2); if (Response == DialogResult.Yes) // Exits the application Application.Exit(); } public void xGameThemeComboBox_SelectedIndexChanged(object sender, EventArgs e) { string folder = Application.StartupPath; string theme = (string)xGameThemeComboBox.Items[xGameThemeComboBox.SelectedIndex]; string path = System.IO.Path.Combine(folder, theme + ".jpg"); Image newImage = new Bitmap(path); if (this.BackgroundImage != null) this.BackgroundImage.Dispose(); { this.BackgroundImage = newImage; } } private void xGameForm_FormClosing(object sender, FormClosingEventArgs e) { // call button1_Click here }

• Making application menus on top of gnome shell

  - by GAP

  Is there a way to put gnome shell components (panel, message tray) to be appear below the popup menu's of other applications such as Java and Gtk Apps. The problem is when there are gtk apps which has tray icons the popup menu tends to appear below the message tray, this was bit ok now in 3.6 because the message tray hides soon as the icon is clicked. But the top bar is still a problem for large menus. When running eclipse with lot of options in the context menu the top most items including the scroll button are under top bar. Is there any thing i can change in the main.js or panel.js to get things below the popup menus ?

• TDBGrid columns design time or run time?

  - by Mawg

  I am using TDBGrid for the first time. I didn't even notice the Columns property in the object inspector and everything went just fine: the grid was filled. Then I saw the Columns property and tried it. When I use the object insector to add items to the Columns property of the grid, they do not all of them show up at run time. To me, it looks like the FieldName property is important. It looks like it is correct, but there are no values in some columns. If I leave this property blank (no columns at all) it seems that the control populates it itself at run time and I do see all the columns. I could live with that. When I set column titles at run time it works, but setting column width does not.

• How to get a List ordered by the List it's filtered by?

  - by DaveDev

  I have a method as follows. It returns a list of MyTypes which appear to be ordered by myType.Id ascending by default. public List<MyType> GetMyTypes(List<int> ids) { return (from myType in db.MyTypes where ids.Contains(myType.Id) select new MyType { MyValue = myType.MyValue }).ToList(); } So if ids contains 302 300 301 the List returned contains items in ascending order. What do I need to do to return List<MyType> in the order of ids? Thanks edit: I've tried orderby ids.IndexOf(myType.Id) but it throws the exception Method 'Int32 IndexOf(Int32)' has no supported translation to SQL.

• Locking a detail view if a user is editing the item...

  - by BenTheDesigner

  Hi All I am developing a user manager which must control access to the detail view of editable items. At present, when a user clicks 'edit', the application queries the link table to check if a user is currently editing that page, if not, it allows access to the page and then inserts a record into the link table preventing another user from editing the same page at the same time. My question is what would the best way to handle the removal of records if say a user exists the browser without saving etc, therefore no action to remove the record. I have a couple of ideas but would like other input before I decide. BenTheDesigner

• How do (or can I) hack a gem temporarily while looking for a bug?

  - by Tom Andersen

  I have a gem installed in my home directory on a laptop (eg not THE server). I have installed ruby 1.9.1 and also some other gems, notably right_aws - which allows access to s3, etc with ruby. All works, except there is a bug when I do a query on SimpleDB, and the returned list of items includes an item with any two byte utf-8 character in its itemName(). So I look through the sources of the right_aws gem installed on my machine, and I can see some places where I would like to test a fix. If I edit the file, save changes, (needing a password), then restart the server (script/server), it ignores my changes. I am quite new at ruby - do you have to 'compile' or other similar move to get the source code changes made take effect? I can see the edited file is changed by viewing it in terminal, etc.

• Having two backgrounds for an active menu item?

  - by HollerTrain

  Hi I have a dynamic menu where the ul li items change in width depending on the text set in the CMS (Joomla). They want the menu item, on mouse over, to both have 1. a repeated background image and 2. an image placed at the top (http://screencast.com/t/Zjk4YTJmNGQ). Now, I'm great with doing the repeated background image on a mouse over and that would be great, but I am not sure how to get both of these images in one css declaration. Any help would be greatly appreciated, as I haven't learned this technique yet :(

• jQuery is only returning first item

  - by Andy

  For some strange reason, whenever I have a selector and expect to get multiple items, jQuery is only returning the first item, instead of the entire collection. This is the HTML I have: <a id="reply-424880" class="reply" href="#" rel="nofollow">Reply</a> <a id="reply-424885" class="reply" href="#" rel="nofollow">Reply</a> And the selector: $('.reply').unbind('click').click(function(event) { ... } I have tried debugging using FireBug, and still get the same results. Using the work around I can get it to work: $('a').each(function (index, element) { if ($(element).attr('class') == 'reply') { $(this).unbind('click').click(function(event) { ... }); } }); I would like to use the built-in functionality instead of my work around. Any idea why only the first element would be returned?

  - by welovedesign

  So I am overriding a theme function by putting the contents in my template.php module, the problem is that it it throwing up loads of undefined index notices because there are lots of functions that are defined in the module. How can I define these in the template.php file and prevent the notices. Note: I know i can turn them off 'uc_cart_block_content' => array( 'variables' => array( 'help_text' => NULL, 'items' => NULL, 'item_count' => NULL, 'item_text' => NULL, 'total' => NULL, 'summary_links' => NULL, 'collapsed' => TRUE, ), 'file' => 'uc_cart.theme.inc', ),

• HTML chrome:// page with select box, onChange failing

  I have a html page. It is chrome://. I have a select box. Giving it the oncommand attribute won't work. So I have to use onchange however you have the typical problem with onchange where it doesnt work if user uses the keyboard arrows, or letters of items to change things. Is there anyway to attach onCommand to my select box? I want to avoid to use onkeyup as then i have to to validation to see if it really changed (which would require me saving previous values).

• Why does var evaluate to System.Object in "foreach (var row in table.Rows)"?

  - by DanM

  When I enter this foreach statement... foreach (var row in table.Rows) ...the tooltip for var says class System.Object I'm confused why it's not class System.Data.DataRow. (In case you're wondering, yes, I have using System.Data at the top of my code file.) If I declare the type explicitly, as in... foreach (DataRow row in table.Rows) ...it works fine with no errors. Also if I do... var numbers = new int[] { 1, 2, 3 }; foreach (var number in numbers) ...var evaluates to struct System.Int32. So, the problem is not that var doesn't work in a foreach clause. So, there's something strange about DataRowCollection where the items don't automatically evaluate to DataRow. But I can't figure out what it is. Does anyone have an explanation?

• Any suggestions in a way to parse headers and links from blog pages using C#?

  - by user344841

  I'm currently self-studying C# in my free time and thought of a "little" project to get me going (and one that I or others will actually find useful). It ended up being more complicated than I thought. Or maybe I'm just thinking it is? Anyway, this project would parse the homepages of the blogs (most of them are Wordpress blogs) I frequent to, take the post headers and the links within those posts and notify me via a balloon tip in the task bar. I can handle the rest except for the way of getting C# to parse the HTML pages for the items I need. C# doesn't seem to have no built-in way to do this. Could anyone point me to the right direction? I just looked into the HTML Agility Pack but I'm still trying to figure it out. Some example code will help much too. Thanks in advance!

• Visual studio 2008 disable auto open on add item(s).

  - by user515

  I have an solution with no projects in it. All I have in the solution are folders. When I add files to a folder in my solution by right clickcontext menuadd existing item, the new items I add open up by default. This is specially annoying when I have to add multiple files. Please note that the files that I am adding are not code files, they are documents and open up in their default application (e.g. .doc opens in word). Is there any way to disable this auto-open feature?

• Javascript running improperly?

  I have a Javascript function that is called from the onchange method in a DropDownList. However I'm getting the error "Cannot have multiple items selected in a DropDownList." on line 14. This happens when the page is reloaded for other purposes. Why is it getting hung here when the method shouldn't even be getting called? Line 12: { Line 13: var hfSelected = document.getElementById("<%=hfSelectedValue.ClientID%>"); Line 14: var ddlExposure = document.getElementById("<%=ddlExposure.ClientID%>"); Line 15: hfSelected.value = ddlExposure.options[ddlExposure.selectedIndex].text + "|" + ddlExposure.options[ddlExposure.selectedIndex].value; Line 16: }
