  • How do I add a custom view to iPhone app's UI?

    - by Dr Dork
    I'm diving into iPad development and I'm still learning how everything works together. I understand how to add standard view (i.e. buttons, tableviews, datepicker, etc.) to my UI using both Xcode and Interface Builder, but now I'm trying to add a custom calendar control (TapkuLibrary) to the left window in my UISplitView application. My question is, if I have a custom view (in this case, the TKCalendarMonthView), how do I programmatically add it to one of the views in my UI (in this case, the RootViewController)? Below are some relevant code snippets from my project... RootViewController interface @interface RootViewController : UITableViewController <NSFetchedResultsControllerDelegate> { DetailViewController *detailViewController; NSFetchedResultsController *fetchedResultsController; NSManagedObjectContext *managedObjectContext; } @property (nonatomic, retain) IBOutlet DetailViewController *detailViewController; @property (nonatomic, retain) NSFetchedResultsController *fetchedResultsController; @property (nonatomic, retain) NSManagedObjectContext *managedObjectContext; - (void)insertNewObject:(id)sender; TKCalendarMonthView interface @class TKMonthGridView,TKCalendarDayView; @protocol TKCalendarMonthViewDelegate, TKCalendarMonthViewDataSource; @interface TKCalendarMonthView : UIView { id <TKCalendarMonthViewDelegate> delegate; id <TKCalendarMonthViewDataSource> dataSource; NSDate *currentMonth; NSDate *selectedMonth; NSMutableArray *deck; UIButton *left; NSString *monthYear; UIButton *right; UIImageView *shadow; UIScrollView *scrollView; } @property (readonly,nonatomic) NSString *monthYear; @property (readonly,nonatomic) NSDate *monthDate; @property (assign,nonatomic) id <TKCalendarMonthViewDataSource> dataSource; @property (assign,nonatomic) id <TKCalendarMonthViewDelegate> delegate; - (id) init; - (void) reload; - (void) selectDate:(NSDate *)date; Thanks in advance for all your help! I still have a ton to learn, so I apologize if the question is absurd in any way. I'm going to continue researching this question right now!

  • Android: simple webview code. ERR: Unable to start Activity

    - by vnshetty
    I have following code: public class reader extends Activity { WebView mWebView; String mFilename; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mWebView = (WebView) findViewById(R.id.webView1); setContentView(R.layout.webview); mWebView.loadUrl("http://www.google.com"); } } When I run this, the emulator shows "Sorry:.. mireader Stopped unexpectedly" error..

  • Read email from incoming mail server(POP)

    - by nccsbim071
    Hi, I have used an open source code from codeproject to read email from incoming mail server(POP Server). The code can be found at following location: http://www.codeproject.com/KB/IP/Pop3MimeClient.aspx So far it works fine i can read emails. My objective of using this code was to retrieve emails from POP server and process them. My problem is: If i use gmails pop server "pop.gmail.com" and run the appplication. I get only those emails that i have not retrieved since the last time i run the application. but if i use my clients pop server everytime i run the application i get all the emails in the pop server. for example: If i use gmail pop server: pop.gmail.com I have three emails in the pop server. I haven't run the application. I am running the application for the first time. Application reads the email, this time i will get 3 all the three email. I run the application second time, my application will not read any emails this time because i have already read the 3 existing one. This is fine, this is what i want. Now i send email to pop.gmail.com. I run the application again for the third time, this time i will only get the email that has just arrived that is the fourth one. This is good behaviour, this is what i want. But if i use my clients pop server: No matter how many times i run the application, it reads all the emails in the mail box. This will create problem for me, because i am thinking of building a window service that will read emails from pop server and process them. This service will run continuously. I will process emails in the pop serve then sleep for let's say 1 minute and the process the emails again. If the application downloaded from codeproject reads all the emails all the time, my clients mailbox can have like thousands for email in this mail box, so this would not be feasible for me. Is there some settings that is to be made at my client's pop server that will allow my application to retrieve only those emails that i have not read since last time i run the service or any help Please help, thanks,

  • Mootools Accordion nonfunctional in Opera

    - by nona
    While working as expected in all other browsers, opera refuses to tween the height of content. oddly enough, as i sat annoyed rapidly clicking it over and over again, if it's closed, and you select some text, and keep clicking the same spot long enough, sometimes it pops open. lol. seriously. ahh, it seems to sometimes open the first time clicked after the page is loaded. wth? the javascript: window.addEvent('domready', function(){ var content_height = [];i=0; $$( '.bio_accordion' ).each(function(item){ i++; content_height.push(item.getElement('.moreInfo').offsetHeight); var thisSlider = new Fx.Slide( item.getElement( '.moreInfo' ), { mode: 'horizontal' } ); thisSlider.hide(); item.getElement('.moreInfo').set('tween').tween('height', '0px'); var morph = new Fx.Morph(item.getElement( '.divToggle' )); var selected = 0; item.getElement( '.divToggle' ).addEvents({ 'mouseenter': function(){ if(!selected) this.morph('.div_highlight'); }, 'mouseleave': function(){ if(!selected) { this.morph('.divToggle'); } }, 'click': function(){ if (!selected){ if (this.getElement('.symbol').innerHTML == '+') this.getElement('.symbol').innerHTML = '-'; else this.getElement('.symbol').innerHTML = '+'; item.getElement('.moreInfo').set('tween', { duration: 1500, transition: Fx.Transitions.Bounce.easeOut }).tween('height', content_height[i]); selected = 1; thisSlider.slideIn(); } else{ if (this.getElement('.symbol').innerHTML == '+') this.getElement('.symbol').innerHTML = '-'; else this.getElement('.symbol').innerHTML = '+'; thisSlider.slideOut(); item.getElement('.moreInfo').set('tween', { duration: 1000, transition: Fx.Transitions.Bounce.easeOut }).tween('height', '0px'); selected = 0; } } }); } ); }); the html: <div class="bio_accordion"> <div class="divToggle">test<span class="symbol">-</span></div> <div class="moreInfo" style="margin-left:10px;"> aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa asdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdf aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa asdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdf aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa asdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdf </div> </div> the css: .bio_accordion { padding:0px; margin:0px; } .divToggle { cursor: pointer; color: #ffffff; background-color:#1089b5; padding: 8px; } .div_highlight { padding-left:30px; padding-right:30px; background-color:#096687; } .moreInfo { padding: 2px; padding-top:15px; padding-bottom:15px; overflow: hidden; } .symbol { float:right; }

  • Forcing a checkbox bound to a DataSource to update when it has not been viewed yet.

    - by Scott Chamberlain
    Here is a test framework to show what I am doing: create a new project add a tabbed control on tab 1 put a button on tab 2 put a check box paste this code for its code (use default names for controls) public partial class Form1 : Form { private List<bool> boolList = new List<bool>(); BindingSource bs = new BindingSource(); public Form1() { InitializeComponent(); boolList.Add(false); bs.DataSource = boolList; checkBox1.DataBindings.Add("Checked", bs, ""); this.button1.Click += new System.EventHandler(this.button1_Click); this.checkBox1.CheckedChanged += new System.EventHandler(this.checkBox1_CheckedChanged); } bool updating = false; private void button1_Click(object sender, EventArgs e) { updating = true; boolList[0] = true; bs.ResetBindings(false); Application.DoEvents(); updating = false; } private void checkBox1_CheckedChanged(object sender, EventArgs e) { if (!updating) MessageBox.Show("CheckChanged fired outside of updating"); } } The issue is if you run the program and look at tab 2 then press the button on tab 1 the program works as expected, however if you press the button on tab 1 then look at tab 2 the event for the checkbox will not fire untill you look at tab 2. The reason for this is the controll on tab 2 is not in the "created" state, so its binding to change the checkbox from unchecked to checked does not happen until after the control has been "Created". checkbox1.CreateControl() does not do anything because according to MSDN CreateControl does not create a control handle if the control's Visible property is false. You can either call the CreateHandle method or access the Handle property to create the control's handle regardless of the control's visibility, but in this case, no window handles are created for the control's children. I tried getting the value of Handle(there is no public CreateHandle() for CheckBox) but still the same result. Any suggestions other than have the program quickly flash all of my tabs that have data-bound check boxes when it first loads? EDIT-- per Jaxidian's suggestion I created a new class public class newcheckbox : CheckBox { public new void CreateHandle() { base.CreateHandle(); } } I call CreateHandle() right after updating = true same results as before.

  • IE8 web slice - CSS problem

    - by rjovic
    Again me with IE8 web slice :) This time i have following problem. I created web slice for IE8 and created button for users where they can choice to add it to their browsers. Code is : <input class="add" type="button" value="Dodaj Xica web slice u IE8!" onclick='window.external.AddToFavoritesBar("http://localhost:51914/Home/GetWebSlice", "xica.rjovic.com", "slice");' /> There is everything fine, and web slice is added to IE8 and web page is displayed correct. But I have problem with CSS in web slice. I defined css in it, but when web slice i rendered there are only black fonts without any css properties. My web slice is defined as : <%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>GetWebSlice</title> <style type="text/css"> p {color: white; } body {background-color: blue; } .container {background-color: red;} </style> </head> <body> <div class="hslice container" id="xica"> <h2 class="entry-title container">Xica web slice</h2> <div class="entry-content"> <h2>Saldo : <b><%= ViewData["total"] %></b></h2> <p><%= ViewData["cardNumber"] %></p> <p>Status : <%= ViewData["status"] %></p> </div> </div> </body> </html> When I try to see web slice directly in my browser then everything is ok, and css is show as expected. Thank you...! EDIT : here is the picture of problem : http://www.deviantpics.com/share-2F10_4BD73E25.html

  • Why is zIndex not working from IE/Javascript?

    - by Vilx-
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <meta http-equiv="X-UA-Compatible" content="IE=7" /> <title>Problem demo</title> </head> <body> <div style="background:red; position:relative;" id='div1'>1. <div style="background:lime; position: absolute; width: 300px;height: 300px; top: 3px; left: 30px" id="div2">3.</div> </div> <div style="background:blue;position:relative;color: white" id="div3">2.</div> <script type="text/javascript">/*<![CDATA[*/ window.onload= function() { // The container of the absolute DIV document.getElementById('div1').style.zIndex = 800; // The lowest DIV of all which obscures the absolute DIV document.getElementById('div2').style.zIndex = 1; // The absolute DIV document.getElementById('div3').style.zIndex = 1000; } /*]]>*/</script> </body> </html> In a nutshell, this script has two DIV elements with position:relative and the first of them has a third DIV with position:absolute in it. It's all set to run on IE-7 standards mode (I'm targeting IE7 and above). I know about the separate z-stacks of IE, so by default the third DIV should be beneath the second DIV. To fix this problem there is some Javascript which sets the z-orders of first and third DIV to 1000, and the z-order of the second DIV to 999. Unfortunately this does not help. If the z-indexes were set in markup, this would work, but why not from JS? Note: This problem does not exist in IE8 standards mode, but I'm targetting IE7, so I can't rely on that. Also, if you save this to your hard drive and then open it up, at first IE complains something about ActiveX and stuff. After you wave it away, everything works as expected. But if you refresh the page, the problem is there again.

  • Proper way to use Linq with WPF

    - by Ingó Vals
    I'm looking for a good guide into the right method of using Linq to Sql together with WPF. Most guides only go into the bare basics like how to show data from a database but noone I found goes into how to save back to the database. Can you answer or point out to me a guide that can answer these questions. I have a separate Data project because the same data will also be used in a web page so I have the repository method. That means I have a seperate class that uses the DataContext and there are methods like GetAllCompanies() and GetCompanyById ( int id ). 1) Where there are collections is it best to return as a IQueryable or should I return a list? Inside the WPF project I have seen reccomendations to wrap the collection in a ObservabgleCollection. 2) Why should I use ObservableCollection and should I use it even with Linq / IQueryable Some properties of the linq entities should be editable in the app so I set them to two-way mode. That would change the object in the observableCollection. 3) Is the object in the ObservableCollection still a instance of the original linq entity and so is the change reflected in the database ( when submitchanges is called ) I should have somekind of save method in the repository. But when should I call it? What happens if someone edits a field but decides not to save it, goes to another object and edits it and then press save. Doesn't the original change also save? When does it not remember the changes to a linq entity object anymore. Should I instance the Datacontext class in each method so it loses scope when done. 4) When and how to call the SubmitChanges method 5) Should I have the DataContext as a member variable of the repository class or a method variable To add a new row I should create a new object in a event ( "new" button push ) and then add it to the database using a repo method. 6) When I add the object to the database there will be no new object in the ObservableCollection. Do I refresh somehow. 7) I wan't to reuse the edit window when creating new but not sure how to dynamically changing from referencing selected item from a listview to this new object. Any examples you can point out.

  • Reading Metadata property of GifBitmapDecoder...why is it null?

    - by David
    How can I read the delay, left and top offset data for each frame of a gif? I've gotten this far. Load the Gif var myGif = new GifBitmapDecoder(uri, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.OnLoad); Get a frame var frame = myGif.Frames[i]; From MSDN: Native Image Format Metadata Queries read (ushort)Metadata.GetQuery("/grctlext/Delay"), (ushort)Metadata.GetQuery("/imgdesc/Left"), (ushort)Metadata.GetQuery("/imgdesc/Top") But two things don't work. First the Metadata property of both the gif and the frame are always null, even if I try different animated gif files. Second, the Metadata property of the frame doesn't seem to have a GetQuery method. How do I run these queries, what did I miss? Edit: Here is sample code that gives me null metadata. Using a fresh install of VS2010 Premium, on a fresh WPF application. The image file is the one in the comments. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows; using System.Windows.Controls; using System.Windows.Data; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Imaging; using System.Windows.Navigation; using System.Windows.Shapes; namespace WpfApplication1 { /// <summary> /// Interaction logic for MainWindow.xaml /// </summary> public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); var uri = new Uri(@"c:\b-414328-animated_gif_.gif"); var myGif = new GifBitmapDecoder(uri, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.OnLoad); var frame = myGif.Frames[0]; Title = ""; Title += "Global Metadata is null: " + (myGif.Metadata == null).ToString(); Title += "; Frame Metadata is null: " + (frame.Metadata == null).ToString(); // Crash due to null metadata //var frameData = (BitmapMetadata)frame.Metadata; //var rate = (ushort)frameData.GetQuery("/grctlext/Delay"); } } }

  • How to redirect to a page using a button tag in html?

    - by Vlad Radulescu
    When I Click a button I want to get redirected to a page. The problem is...if I use the normal sintax , the button works fine, but If I apply some css to id by ussing # and .(classes) ,the button it`s not working any more ?! How can I keep my css and functionality at the same time ?! This is my code: <body> <input id="buttonrain" class="classname" type="button" onClick="window.location.href='rain.html'" value="Rain" /> <!--or <a href="rain.html" id="buttonrain" class="classname">Rain</a> still not working--> </body> CSS FILE html { min-width: 100%; min-height: 100%; } body{ width: 1024px; height:600px; background:white; margin:0px; padding:0px 0px; display:block; overflow:hidden; } .classname { -moz-box-shadow:inset 0px 1px 0px 0px #ffffff; -webkit-box-shadow:inset 0px 1px 0px 0px #ffffff; box-shadow:inset 0px 1px 0px 0px #ffffff; background:-webkit-gradient( linear, left top, left bottom, color-stop(0.05, #f0ea3c), color-stop(1, #dfdfdf) ); background:-moz-linear-gradient( center top, #f0ea3c 5%, #dfdfdf 100% ); filter:progid:DXImageTransform.Microsoft.gradient(startColorstr='#f0ea3c', endColorstr='#dfdfdf'); background-color:#f0ea3c; -moz-border-radius:6px; -webkit-border-radius:6px; border-radius:6px; border:1px solid #dcdcdc; display:inline-block; color:#0f000f; font-family:Verdana; font-size:15px; font-weight:bold; padding:18px 9px; text-decoration:none; text-shadow:1px 1px 0px #ffffff; position:relative; bottom:250px; }.classname:active { position:relative; top:1px; } #buttonrain{ left:80px; }

  • set the focus on the scroller when button is clicked

    - by liz
    hi i have a script <script type="text/javascript"> window.addEvent('domready', function(){ var totIncrement = 0; var increment = 560; var maxRightIncrement = increment*(-6); var fx = new Fx.Style('slider-list', 'margin-left', { duration: 1000, transition: Fx.Transitions.Back.easeInOut, wait: true }); //------------------------------------- // EVENTS for the button "previous" $('previous').addEvents({ 'click' : function(event){ if(totIncrement<0){ totIncrement = totIncrement+increment; fx.stop() fx.start(totIncrement); } } }); //------------------------------------- // EVENTS for the button "next" $('next').addEvents({ 'click' : function(event){ if(totIncrement>maxRightIncrement){ totIncrement = totIncrement-increment; fx.stop() fx.start(totIncrement); } } }) }); </script> in mootools v1.1 it makes a scroller function at the bottom of my html page. but when i click the next button the page's focus moves to the top of the page. how do i keep it on the scroller? this is the html fragment: <h3>Our Pastas</h3> <div id="slider-buttons"> <a href="#" id="previous">Previous</a> | <a href="#" id="next">Next</a&gt; </div> <div id="slider-stage"> <ul id="slider-list"> <li class="list_item"> <div id="thumbnail"><a href="xxx/product-catalog/pasta/long-pasta-in-brown-bags/bucatini"><img src="xxx/images/stories/products/_thumb1/bucatini.gif"></a></div><h4><a href="xxx/product-catalog/pasta/long-pasta-in-brown-bags/bucatini">Rustichella d'Abruzzo Bucatini</a></h4> </li> <li class="list_item"> <div id="thumbnail"><a href="xxx/product-catalog/pasta/pasta-in-trays/calamarata"><img src="xxx/images/stories/products/_thumb1/calamarata.jpg"></a></div><h4><a href="xxx/product-catalog/pasta/pasta-in-trays/calamarata">Rustichella d'Abruzzo Calamarata</a></h4> </li> <li class="list_item"> <div id="thumbnail"><a href="xxx/product-catalog/pasta/pasta-in-trays/cannolicchi"><img src="xxx/images/stories/products/_thumb1/cannolicchi.jpg"></a></div><h4><a href="xxx/product-catalog/pasta/pasta-in-trays/cannolicchi">Rustichella d'Abruzzo Cannolicchi</a></h4> </li> </ul></div>

  • HowTo stick QDialog to Screen Borders like Skype do?

    - by mosg
    Hello. A long time ago I tried to find method how to stick QDialog window to screen borders for my small projects like Skype windows do it, but I failed. May be I was looking this code not in the right place, so now I'm looking the solution here, on stack! :) So, does any one have a deal with some kind of such code, links, samples? In my opinion, we have to reimplement QDialog moveEvent function, like below, but that code does not working: void CDialog::moveEvent(QMoveEvent * event) { QRect wndRect; int leftTaskbar = 0, rightTaskbar = 0, topTaskbar = 0, bottomTaskbar = 0; // int top = 0, left = 0, right = 0, bottom = 0; wndRect = this->frameGeometry(); // Screen resolution int screenWidth = QApplication::desktop()->width(); int screenHeight = QApplication::desktop()->height(); int wndWidth = wndRect.right() - wndRect.left(); int wndHeight = wndRect.bottom() - wndRect.top(); int posX = event->pos().x(); int posY = event->pos().y(); // Snap to screen border // Left border if (posX >= -m_nXOffset + leftTaskbar && posX <= leftTaskbar + m_nXOffset) { //left = leftTaskbar; this->move(leftTaskbar, posY); return; } // Top border if (posY >= -m_nYOffset && posY <= topTaskbar + m_nYOffset) { //top = topTaskbar; this->move(posX, topTaskbar); return; } // Right border if (posX + wndWidth <= screenWidth - rightTaskbar + m_nXOffset && posX + wndWidth >= screenWidth - rightTaskbar - m_nXOffset) { //right = screenWidth - rightTaskbar - wndWidth; this->move(screenWidth - rightTaskbar - wndWidth, posY); return; } // Bottom border if (posY + wndHeight <= screenHeight - bottomTaskbar + m_nYOffset && posY + wndHeight >= screenHeight - bottomTaskbar - m_nYOffset) { //bottom = screenHeight - bottomTaskbar - wndHeight; this->move(posX, screenHeight - bottomTaskbar - wndHeight); return; } QDialog::moveEvent(event); } Thanks.

I have copied this into a different test program and it works fine, I create a misc.html file and reopen it with both FileInputStream and manually. I would be worried about Administrator rights but the Test program works fine when I run it RIGHT after the problem program. I also have checked if the file exists and is a file with File methods and it is as well. Is this a result of me not closing a previous Input/Output properly? I've tried to check everything and I am fairly positive I close all streams as soon as they finish... Help! :)

  • What is a good platform for building a game framework targetting both web and native languages?

    - by fuzzyTew
    I would like to develop (or find, if one is already in development) a framework with support for accelerated graphics and sound built on a system flexible enough to compile to the following: native ppc/x86/x86_64/arm binaries or a language which compiles to them javascript actionscript bytecode or a language which compiles to it (actionscript 3, haxe) optionally java I imagine, for example, creating an API where I can open windows and make OpenGL-like calls and the framework maps this in a relatively efficient manner to either WebGL with a canvas object, 3d graphics in Flash, OpenGL ES 2 with EGL, or desktop OpenGL in an X11, Windows, or Cocoa window. I have so far looked into these avenues: Building the game library in haXe Pros: Targets exist for php, javascript, actionscript bytecode, c++ High level, object oriented language Cons: No support for finally{} blocks or destructors, making resource cleanup difficult C++ target does not allow room for producing highly optimized libraries -- the foreign function interface requires all primitive types be boxed in a wrapper object, as if writing bindings for a scripting language; these feel unideal for real-time graphics and audio, especially exporting low-level functions. Doesn't seem quite yet mature Using the C preprocessor to create a translator, writing programs entirely with macros Pros: CPP is widespread and simple to use Cons: This is an arduous task and probably the wrong tool for the job CPP implementations differ widely in support for features (e.g. xcode cpp has no variadic macros despite claiming C99 compliance) There is little-to-no room for optimization in this route Using llvm's support for multiple backends to target c/c++ to web languages Pros: Can code in c/c++ LLVM is a very mature highly optimizing compiler performing e.g. global inlining Targets exist for actionscript (alchemy) and javascript (emscripten) Cons: Actionscript target is closed source, unmaintained, and buggy. Javascript targets do not use features of HTML5 for appropriate optimization (e.g. linear memory with typed arrays) and are immature An LLVM target must convert from low-level bytecode, so high-level constructs are lost and bloated unreadable code is created from translating individual instructions, which may be more difficult for an unprepared JIT to optimize. "jump" instructions cause problems for languages with no "goto" statements. Using libclang to write a translator from C/C++ to web languages Pros: A beautiful parsing library providing easy access to the code structure Can code in C/C++ Has sponsored developer effort from Apple Cons: Incomplete; current feature set targets IDEs. Basic operators are unexposed and must be manually parsed from the returned AST element to be identified. Translating code prior to compilation may forgo optimizations assumed in c/c++ such as inlining. Creating new code generators for clang to translate into web languages Pros: Can code in C/C++ as libclang Cons: There is no API; code structure is unstable A much larger job than using libclang; the innards of clang are complex Building the game library in Common Lisp Pros: Flexible, ancient, well-developed language Extensive introspection should ease writing translators Translators exist for at least javascript Cons: Unfamiliar language No standardized library functions, widely varying implementations Which of these avenues should I pursue? Do you know of any others, or any systems that might be useful? Does a general project like this exist somewhere already? Thank you for any input.

  • How to update the session values on partial post back and how to make Javascript use the new values

    - by Mano
    The problem I am facing is the I am passing values to javascript to draw a graph using session values in the code behind. When page loads it take the value from the session and creates the graph, when I do partial post back using a Update Panel and Timer, I call the method to add values to the session and it does it. public void messsagePercentStats(object sender, EventArgs args) { ... if (value >= lowtarg && value < Toptarg) { vProgressColor = "'#eaa600'"; } else if (value >= Toptarg) { vProgressColor = "'#86cf21'"; } Session.Add("vProgressColor", vProgressColor); Session.Add("vProgressPercentage", "["+value+"],["+remaining+"]"); } } I use the update panel to call the above method <asp:ScriptManager ID="smCharts" runat="server" /> <asp:UpdatePanel runat="server" ID="Holder" OnLoad="messsagePercentStats" UpdateMode="Conditional"> <ContentTemplate> <asp:Timer ID="Timer1" runat="server" Interval="5000" OnTick="Timer_Tick" /> and the timer_tick method is executed every 5 seconds protected void Timer_Tick(object sender, EventArgs args) { ScriptManager.RegisterStartupScript(this, this.GetType(), "key", "r.init();", true); ResponseMetric rm = new ResponseMetric(); Holder.Update(); } I use ScriptManager.RegisterStartupScript(this, this.GetType(), "key", "r.init();", true); to call the r.init() Java script method to draw the graph on post back and it works fine. Java Script: var r = { init : function(){ r = Raphael("pie"), data2 = [<%= Session["vProgressPercentage"] %>]; axisx = ["10%", "20%"]; r.g.txtattr.font = "12px 'Fontin Sans', Fontin-Sans, sans-serif"; r.g.barchart(80, 25, 100, 320, data2, { stacked: true, colors: [<%= Session["vProgressColor"] %>,'#fff'] }); axis2 = r.g.axis(94, 325, 280, 0, 100, 10, 1); } } window.onload = function () { r.init(); }; This Java Script is not getting the new value from the session, it uses the old value when the page was loaded. How can I change the code to make sure the JS uses the latest session value.

  • Custom activity designers in Workflow Foundation 3.5: How do they work?

    - by stakx
    Intent of this post: I realise that Workflow Foundation is not extremely popular on StackOverflow and that there will probably be not many answers, or none at all. This post is intended as a resource to people trying to customise workflow activities' appearance through custom designer classes. Goals: I am attempting to create a custom designer class for Workflow activities to achieve the following: Make activities look less technical. For example, I don't necessarily want to see the internal object name as the activity's "title" -- instead, I'd like to see something more descriptive. Display the values of certain properties beneath the title text. I would like to see some properties' values directly underneath the title so that I don't need to look somewhere else (namely, at the Properties window). Provide custom drop areas and draw custom internal arrows. As an example, I would like to be able to have custom drop areas in very specific places. What I found out so far: I created a custom designer class deriving from SequentialActivityDesigner as follows: [Designer(typeof(SomeDesigner))] public partial class SomeActivity: CompositeActivity { ... } class PlainDesigner : SequentialActivityDesigner { ... } Through overriding some properties and the OnPaint method, I found out about the following correspondences between the properties and how the activity will be displayed: Figure 1. Relationship between some properties of an SequentialActivityDesigner and the displayed activity. Possible solutions for goal #1 (make activities look less technical) and goal #2 (display values of properties beneath title text): The displayed title can be changed through the Title property. If more room is required to display additional information beneath the title, the TitleHeight property can be increased (ie., override the property and make it return base.TitleHeight + n, where n is some positive integer). Override the OnPaint method and draw additional text in the area reserved through TitleHeight. Open questions: What are the connectors, connections, and connection points used for? They seem to be necessary, but for what purpose? While the drop targets can be got through the GetDropTargets method, it seems that this is not necessarily where the designer will actually place dropped activities. When an activity is dragged across a workflow, the designer displays little green plus signs where activities can be dropped; how does it figure out the locations of these plus signs? How does the designer figure out where to draw connector lines and arrows?

  • Adding NavigationControl to a TabBar Application containing UITableViews

    - by kungfuslippers
    Hi, I'm new to iPhone dev and wanted to get advice on the general design pattern / guide for putting a certain kind of app together. I'm trying to build a TabBar type application. One of the tabs needs to display a TableView and selecting a cell from within the table view will do something else - maybe show another table view or a web page. I need a Navigation Bar to be able to take me back from the table view/web page. The approach I've taken so far is to: Create an app based around UITabBarController as the rootcontroller i.e. @interface MyAppDelegate : NSObject <UIApplicationDelegate> { IBOutlet UIWindow *window; IBOutlet UITabBarController *rootController; } Create a load of UIViewController derived classes and associated NIBs and wire everything up in IB so when I run the app I get the basic tabs working. I then take the UIViewController derived class and modify it to the following: @interface MyViewController : UIViewController<UITableViewDataSource, UITableViewDelegate> { } and I add the delegate methods to the implementation of MyViewController - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 2; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } if (indexPath.row == 0) { cell.textLabel.text = @"Mummy"; } else { cell.textLabel.text = @"Daddy"; } return cell; } Go back to IB , open MyViewController.xib and drop a UITableView onto it. Set the Files Owner to be MyViewController and then set the delegate and datasource of the UITableView to be MyViewController. If I run the app now, I get the table view appearing with mummy and daddy working nicely. So far so good. The question is how do I go about incorporating a Navigation Bar into my current code for when I implement: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath() { // get row selected NSUInteger row = [indexPath row]; if (row == 0) { // Show another table } else if (row == 1) { // Show a web view } } Do I drop a NavigationBar UI control onto MyControllerView.xib ? Should I create it programmatically? Should I be using a UINavigationController somewhere ? I've tried dropping a NavigationBar onto my MyControllerView.xib in IB but its not shown when I run the app, only the TableView is displayed.

  • Can you help me optimize this code for finding factors of a number? I'm brushing up on my math progr

    - by Sergio Tapia
    I've never really bothered with math programming, but today I've decided to give it a shot. Here's my code and it's working as intended: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows; using System.Windows.Controls; using System.Windows.Data; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Imaging; using System.Windows.Navigation; using System.Windows.Shapes; namespace PrimeFactorization { /// <summary> /// Interaction logic for MainWindow.xaml /// </summary> public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); } private void btnSubmit_Click(object sender, RoutedEventArgs e) { List<int> primeFactors = FindPrimeFactors(Convert.ToInt32(txtNumber.Text)); primeFactors.Sort(); for (int i = 0; i < primeFactors.Count; i++) { listBoxFoundNumbers.Items.Add(primeFactors[i]); } } private List<int> FindPrimeFactors(int number) { List<int> factors = new List<int>(); factors.Add(1); factors.Add(number); for (int i = 2; i < number; i++) { if (number % i == 0) { int holder = number / i; //If the number is in the list, don't add it again. if (!factors.Contains(i)) { factors.Add(i); } //If the number is in the list, don't add it again. if (!factors.Contains(holder)) { factors.Add(holder); } } } return factors; } } } The only problem I can see with my code is that it will iterate through to the bitter end, even though there will definitely not be any factors. For example, imagine I wrote in 35. My loop will go up to 35 and check 24,25,26,27...etc. Not very good. What do you recommend?

    Hi all: I've been trying to do as the client requested : redirect to campaign page then to destination page once a customer clicks on the top banner in swf format. You can check what's been done at :http://ausdcf.org If you are using Firefox, Chrome or Safari, I suspect you can reach the destination page. However, if you are using IE or Opera, I doubt it. I think to cause of such a weird problem is: The swf ojbects don't have a link to url, SO I have to hack the theme template file like this : <div id="header">'; /* * A quick and dirty way to put some swf into PHP, and rotate among them ... */ //available banners $banners = array( 'http://localhost/smf/flash/banner_fertalign_1.swf', 'http://localhost/smf/flash/banner_fertalign_2.swf', 'http://localhost/smf/flash/banner_fertalign_3.swf' ); //get random banner srand((double) microtime() * 1000000); $rand = rand(0,count($banners)-1); echo '<div id="top_banner_clickable">'; echo '<div id="top_banner_wrapper">'; echo '<object width="400" height="60">'; echo '<param name="wmode" value="transparent">'; echo '<embed wmode="transparent" src="'.$banners[$rand].'" '; echo 'width="400" height="60" type="application/x-shockwave-flash"'; echo 'pluginspage="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash" />'; echo '</object>'; echo '</div>'; echo '</div>'; And the related jQuery code is like this: /* master.js */ $(document).ready(function() { $("#top_banner_clickable").click(function() { window.location ="http://ausdcf.org/campaign/"; }); }); I absolutely know nothing about Flash or embedded objects. I guess that's the cause of this problem. Plus, I don't know why it works with some browsers but not all... I even tried to add a z-index to the wrapper div in css like this: #top_banner_clickable { z-index : 100; } No this wouldn't do, either... Is there a way to go around this issue? Many thanks in advance.
