  • Mimicking a HBox / VBox with CSS

    - by Daniel Hai
    I'm an old school tables guy, and am pretty baffled when it comes to modern HTML. I'm trying to something as simple as vertical / horizontal layouts (i.e. Flex's hbox/vbox), but am having major difficulty replicating them. An old table would look something like this for an HBox: <table width="100%" height="100"> <tr valign="middle"> <td nowrap style="background-color:#CCC">I am text on grey</td> <td width="50%" valign="top">displays top</td> <td width="50%" align="right">Autosize Fill (displays bottom right)</td> </tr> </table> Now I'm trying to do this with div's, but to no avail. When using display:inline, I cannot set a percentage width -- it only takes explicit widths. When using float:left, settings 100% percentage width causes it to really be 100% and pushes the next div down. Here's the code I've been playing with: <html> <head> </head> <style type="text/css"> div.test { background-color: #EE9; padding:5px;} body { font-family: Arial; } ul { list-style-type:none; } ul li { float:left; } .hboxinline div { display: inline; } .hboxfloat div { float:left; } .cellA { background-color:#CCC; width:100%; } .cellB { background-color:#DDD; min-width:100; } .cellC { background-color:#EEE; min-width:200; } </style> <body> A = 100%, b = 100, c = 200 <div class="test">old school table <table cellpadding="0" cellspacing="0"> <tr> <td class="cellA">A</td> <td class="cellB">B</td> <td class="cellC">C</td> </tr> </table></div> <br/> <div class="test"> float:left <div class="hboxinline"> <div class="cellA">A</div> <div class="cellB">B</div> <div class="cellC">C</div> </div> </div> <br/> <div class="test">ul / li <ul class="ulli"> <li class="cellA">A</li> <li class="cellB">B</li> <li class="cellC">C</li> </ul> </div> <br/> <div class="test"> display:inline <div class="hboxfloat"> <div class="cellA">A</div> <div class="cellB">B</div> <div class="cellC">C</div> </div> </div> </body> </html>

  • MS-Access: What could cause one form with a join query to load right and another not?

    - by Daniel Straight
    Form1 Form1 is bound to Table1. Table1 has an ID field. Form2 Form2 is bound to Table2 joined to Table1 on Table2.Table1_ID=Table1.ID Here is the SQL (generated by Access): SELECT Table2.*, Table1.[FirstFieldINeed], Table1.[SecondFieldINeed], Table1.[ThirdFieldINeed] FROM Table1 INNER JOIN Table2 ON Table1.ID = Table2.[Table1_ID]; Form2 is opened with this code in Form1: DoCmd.RunCommand acCmdSaveRecord DoCmd.OpenForm "Form2", , , , acFormAdd, , Me.[ID] DoCmd.Close acForm, "Form1", acSaveYes And when loaded runs: Me.[Table1_ID] = Me.OpenArgs When Form2 is loaded, fields bound to columns from Table1 show up correctly. Form3 Form3 is bound to Table3 joined to Table2 on Table3.Table2_ID=Table2.ID Here is the SQL (generated by Access): SELECT Table3.*, Table2.[FirstFieldINeed], Table2.[SecondFieldINeed] FROM Table2 INNER JOIN Table3 ON Table2.ID = Table3.[Table2_ID]; Form3 is opened with this code in Form2: DoCmd.RunCommand acCmdSaveRecord DoCmd.OpenForm "Form3", , , , acFormAdd, , Me.[ID] DoCmd.Close acForm, "Form2", acSaveYes And when loaded runs: Me.[Table2_ID] = Me.OpenArgs When Form3 is loaded, fields bound to columns from Table2 do not show up correctly. WHY? UPDATES I tried making the join query into a separate query and using that as my record source, but it made no difference at all. If I go to the query for Form3 and view it in datasheet view, I can see that the information that should be pulled into the form is there. It just isn't showing up on the form.

  • iPhone SDK - Comparing characters in string

    - by Karl Daniel
    Basically what I'm trying to do is compare 2 strings one from a plist and one from the user's input. I use a while loop to step through each character and compare it and if true then I increase an integer then once the loop has finished I work out the percentage correct / similarity of the plist answer and the user's answer. I seem to be having a problem however as the only return I'm getting is 0. Below is the code I'm using... The code below is all functioning and the question no longer requires answering... Working code... answerLength = boxAnswer.length; //Gets number of characters of first string. plistLength = plistAnswer.length; //Gets number of characters of second string. characterRange = 0; //Sets the variable for which character to look at. charactersCorrect = 0; //Sets the variable of number of matching characters. unichar answerCharacter; //Declares a unichar for the first string. unichar plistCharacter; //Declares a unichar for the second string. while (answerLength > 0 && plistLength > 0) { answerCharacter = [boxAnswer characterAtIndex:characterRange]; //Gets character of first string at the index of the range integer. plistCharacter = [plistAnswer characterAtIndex:characterRange]; //Gets character of second string at the index of the range integer. answerLength--; //Reduces number of characters left to compare. plistLength--; characterRange++; //Increases integer to tell it to look at next character in string. if (answerCharacter == plistCharacter) { //Checks to see if character of first string and character of second string match. charactersCorrect++; //If true increases the number correct. } } //Works out percentage of matching characters out of the total string. totalChar = plistAnswer.length; totalPercentage = (charactersCorrect/totalChar)*100; percentageCorrect.text = [NSString stringWithFormat:@"%i%%",totalPercentage]; Variable Declarations... int answerLength; int plistLength; int characterRange; double totalChar; double charactersCorrect; int totalPercentage;

  • Any good tutorials or resources for learning how to design a scalable and "component" based game 'fr

    - by CodeJustin.com
    In short I'm creating a 2D mmorpg and unlike my last "mmo" I started developing I want to make sure that this one will scale well and work well when I want to add new in-game features or modify existing ones. With my last attempt with an avatar chat within the first few thousand lines of code and just getting basic features added into the game I seen my code quality lowering and my ability to add new features or modify old ones was getting lower too as I added more features in. It turned into one big mess that some how ran, lol. This time I really need to buckle down and find a design that will allow me to create a game framework that will be easy to add and remove features (aka things like playing mini-games within my world or a mail system or buddy list or a new public area with interactive items). I'm thinking that maybe a component based approach MIGHT be what I'm looking for but I'm really not sure. I have read documents on mmorpg design and 2d game engine architecture but nothing really explained a way of designing a game framework that will basically let me "plug-in" new features into the main game and use the resources of the main game without changing much within my 'main game code'. Hope someone understands what I mean, any help will is appreciated.

  • Accessing the project system from a Visual Studio MEF Editor extension

    - by Daniel Plaisted
    I'm writing a Visual Studio editor extension using the VS 2010 SDK RC. I'd like to be able to figure out what the references of the current project are. How do I get access to the project corresponding to the current editor? The documentation on editor extensions doesn't seem to include information on how to access non-editor parts of Visual Studio. I did some searching and it looks like in VS2008 you could write add-ins that would access the project system, but I'm trying to get at this functionality from a MEF editor extension.

  • jquery ui 1.7 autocomplete show dialog on select

    - by Daniel S
    Hello, I am using an autocomplete widget, and would like a dialog to show when an item is selected. The dialog does show up, but I want a field in the dialog to receive focus when it opens. Here is what I have tried so far: //HTML <form action="#"> <p><input id="busca" /></p> </form> <div id="agregar" title="Agregar Parte"> <label for="cantidad">Cantidad:</label> <input name="cantidad" id="cantidad" size="3" /> </div> //jquery $(function(){ $("#agregar").dialog({ autoOpen: false, //also tried open: function(){$("#cantidad").focus()} } ); //.bind("dialogfocus", ... ) does not work either $("#agregar").bind("focus", function(){ $("#cantidad").focus(); }); $("#busca").autocomplete({ source: "/carrito/autocomplete/", minLength: 1, select: function(e, ui) { $("#agregar").dialog("open"); } }); }); I think autoselect's default behavior is still doing something as the autoselect widget receives focus after the dialog is shown. Any help would be greatly appreciated.

  • NSFetchedResultsController titleForHeaderInSection with formatted NSDate

    - by Daniel Granger
    In my Core Data app I am using a FetchedResultsController. Usually to set titles for headers in a UITableView you would implement the following method like so: - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { id <NSFetchedResultsSectionInfo> sectionInfo = [[<#Fetched results controller#> sections] objectAtIndex:section]; return [sectionInfo name]; } where [sectionInfo name] returns a NSString. my sectionKeyPath is based on an NSDate and this all works fine apart from the section headers it gives me are the raw date description strings (e.g. 12/12/2009 12:32:32 +0100) which look a bit of a mess in a header! So I want to use a date formatter on this to make a nice header like "Apr 17 2010" but I can't do that with the [sectionInfo name] as this is NSString! Any Ideas? Many Thanks

  • Optimizing UITableView

    - by Daniel Granger
    I have a UITableview made up with a custom cell loaded from a nib. This custom cell has 9 UILabel s and thats all. When scrolling the table on my iPhone the tables scrolling motion is slightly jerky, its not as smooth as other tableviews! (On the simulator it scrolls fine but I guess its using the extra power of my mac) Are there any tips to help optimize this or any tableview or methods to help find the bottleneck. Many Thanks

  • Dynamic URL -> Controller mapping for routes in Rails

    - by Daniel Beardsley
    I would like to be able to map URLs to Controllers dynamically based on information in my database. I'm looking to do something functionally equivalent to this (assuming a View model): map.route '/:view_name', :controller => lambda { View.find_by_name(params[:view_name]).controller } Others have suggested dynamically rebuilding the routes, but this won't work for me as there may be thousands of Views that map to the same Controller

  • UIKeyboard turn Caps Lock on

    - by Daniel Granger
    I need my user to input some data like DF-DJSL so I put this in the code: theTextField.autocapitalizationType = UITextAutocapitalizationTypeAllCharacters; But unfortunately what happens is the first to letter type in CAPS but then letter immediately after typing the hyphen will be in lower case and then the rest return to CAPS therefore producing output like this (unless the user manually taps the shift button after typing a hyphen): DF-dJSL How can I fix this? Many Thanks

  • How do you find a functions virtual call address in assembly?

    - by Daniel
    I've googled around but i'm not sure i am asking the right question or not and i couldn't find much regardless, perhaps a link would be helpful. I made a c++ program that shows a message box, then I opened it up with Ollydbg and went to the part where it calls MessageBoxW. The call address of MessageBoxW changes each time i run the app as windows is updating my Imports table to have the correct address of MessageBoxW. So my question is how do i find the virtual addres of MessageBoxW to my imports table and also how can i use this in ollydbg? Basically I'm trying to make a code cave in assembly to call MessageBoxW again. I got fairly close once by searching the executable with a hex editor and found the position of the call, and I think I found the virtual address. But when i call that virtual address in olly and saved it to the executable, the next time i opened it the call was replaced with a bunch of DB xyz (which looked like the virtual address but why did the call get removed? Sorry if my terminology is off as i'm new to this so i'm not quite sure what to call things.

  • Make a div fall off the page

    - by Daniel Hertz
    Hey, So I have been playing with jQuery for a good time now and I'm trying to get an effect to work properly. I have a main square div in the middle of the page and when someone clicks a link I want the box to look like its falling off the page and disappear, revealing a new page behind it. I'v been playing with the easing plugin but I can seem to get what I want to work. Basically I have the div's top margin or just top distance increased to a large number. However, this just makes the div fall but it also expands my page and its just much lower on the page. I basically want the div to fall out of site and not change the dimensions of the site. Anyone know how to do that? Thanks! Danny

  • Why doesn't the conditional operator correctly allow the use of "null" for assignment to nullable ty

    - by Daniel Coffman
    This will not compile, stating "Type of conditional expression cannot be determined because there is no implicit conversion between 'System.DateTime' and ''" task.ActualEndDate = TextBoxActualEndDate.Text != "" ? DateTime.Parse(TextBoxActualEndDate.Text) : null; This works just fine if (TextBoxActualEndDate.Text != "") task.ActualEndDate = DateTime.Parse(TextBoxActualEndDate.Text); else task.ActualEndDate = null;

  • Mysterious socket / HttpWebRequest timeouts

    - by Daniel Mošmondor
    I have a great app for capturing shoutcast streams :-) . So far, it worked with a charm on dozens of machines, and never exhibited behaviour I found now, which is ultimately very strange. I use HttpWebRequest to connect to the shoutcast server and when I connect two streams, everything's OK. When I go for third one, response = (HttpWebResponse)request.GetResponse(); throws with Connection Timeout exception. WTF? I must point out that I had to create .config for the application in order to allow my headers to be sent out from the application, otherwise it wouldn't work at all. Here it is: <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.net> <settings> <httpWebRequest useUnsafeHeaderParsing = "true" /> </settings> </system.net> </configuration> Does any of this ring a bell?

  • Is there a standard mapping between JSON and Protocol Buffers?

    - by Daniel Earwicker
    From a comment on the announcement blog post: Regarding JSON: JSON is structured similarly to Protocol Buffers, but protocol buffer binary format is still smaller and faster to encode. JSON makes a great text encoding for protocol buffers, though -- it's trivial to write an encoder/decoder that converts arbitrary protocol messages to and from JSON, using protobuf reflection. This is a good way to communicate with AJAX apps, since making the user download a full protobuf decoder when they visit your page might be too much. It may be trivial to cook up a mapping, but is there a single "obvious" mapping between the two that any two separate dev teams would naturally settle on? If two products supported PB data and could interoperate because they shared the same .proto spec, I wonder if they would still be able to interoperate if they independently introduced a JSON reflection of the same spec. There might be some arbitrary decisions to be made, e.g. should enum values be represented by a string (to be human-readable a la typical JSON) or by their integer value? So is there an established mapping, and any open source implementations for generating JSON encoder/decoders from .proto specs?

  • Replacing string literal values in Visual Studio project templates

    - by Daniel A. White
    I notice when I create a project template from an existing project in my solution, it does a semi-string replace to update references. However, it does not replace string literals. It does update my web.config file, but not code files. The project template: namespace MyTemplateProject { class MyClass { public string GetStringValue() { return "MyProjectTemplate"; } } } The generated code when used as a template: namespace MyActualNewProject { class MyClass { public string GetStringValue() { return "MyProjectTemplate"; } } } How can I instruct the template maker to replace "MyProjectTemplate" wih "MyActualNewProject"?

  • Using Regex Replace when looking for un-escaped characters

    - by Daniel Hollinrake
    I've got a requirement that is basically this. If I have a string of text such as "There once was an 'ugly' duckling but it could never have been \'Scarlett\' Johansen" then I'd like to match the quotes that haven't already been escaped. These would be the ones around 'ugly' not the ones around 'Scarlett'. I've spent quite a while on this using a little C# console app to test things and have come up with the following solution. private static void RegexFunAndGames() { string result; string sampleText = @"Mr. Grant and Ms. Kelly starred in the film \'To Catch A Thief' but not in 'Stardust' because they'd stopped acting by then"; string rePattern = @"\\'"; string replaceWith = "'"; Console.WriteLine(sampleText); Regex regEx = new Regex(rePattern); result = regEx.Replace(sampleText, replaceWith); result = result.Replace("'", @"\'"); Console.WriteLine(result); } Basically what I've done is a two step process find those characters that have already been escaped, undo that then do everything again. It sounds a bit clumsy and I feel that there could be a better way.

  • WPF / Silverlight Binding when setting DataTemplate programically

    - by Daniel
    I have my little designer tool (my program). On the left side I have TreeView and on the right site I have Accordion. When I select a node I want to dynamically build Accordion Items based on Properties from DataContext of selected node. Selecting nodes works fine, and when I use this sample code for testing it works also. XAML code: <layoutToolkit:Accordion x:Name="accPanel" SelectionMode="ZeroOrMore" SelectionSequence="Simultaneous"> <layoutToolkit:AccordionItem Header="Controller Info"> <StackPanel Orientation="Horizontal" DataContext="{Binding}"> <TextBlock Text="Content:" /> <TextBlock Text="{Binding Path=Name}" /> </StackPanel> </layoutToolkit:AccordionItem> </layoutToolkit:Accordion> C# code: private void treeSceneNode_SelectedItemChanged(object sender, RoutedPropertyChangedEventArgs<object> e) { if (e.NewValue != e.OldValue) { if (e.NewValue is SceneNode) { accPanel.DataContext = e.NewValue; //e.NewValue is a class that contains Name property } } } But the problem occurs when I'm trying to achive this using DateTemplate and dynamically build AccordingItem, the Binding is not working: <layoutToolkit:Accordion x:Name="accPanel" SelectionMode="ZeroOrMore" SelectionSequence="Simultaneous" /> and DataTemplate in my ResourceDictionary <DataTemplate x:Key="dtSceneNodeContent"> <StackPanel Orientation="Horizontal" DataContext="{Binding}"> <TextBlock Text="Content:" /> <TextBlock Text="{Binding Path=Name}" /> </StackPanel> </DataTemplate> and C# code: private void treeSceneNode_SelectedItemChanged(object sender, RoutedPropertyChangedEventArgs<object> e) { if (e.NewValue != e.OldValue) { ResourceDictionary rd = new ResourceDictionary(); rd.Source = new Uri("/SilverGL.GUI;component/SilverGLDesignerResourceDictionary.xaml", UriKind.RelativeOrAbsolute); if (e.NewValue is SceneNode) { accPanel.DataContext = e.NewValue; AccordionItem accController = new AccordionItem(); accController.Header = "Controller Info"; accController.ContentTemplate = rd["dtSceneNodeContent"] as DataTemplate; accPanel.Items.Add(accController); } else { // Other type of node } } } I really need help with this issue. Thanks for any support.

  • Creating multiple log files of different content with log4j

    - by Daniel
    Is there a way to configure log4j so that it outputs different levels of logging to different appenders? I'm trying to set up multiple log files. The main log file would catch all INFO and above messages for all classes. (In development, it would catch all DEBUG and above messages, and TRACE for specific classes.) Then, I would like to have a separate log file. That log file would catch all DEBUG messages for a specific subset of classes, and ignore all messages for any other class. Is there a way to get what I'm after? Thanks, Dan
