• Most simple way to do holiday calculation?

  - by brainfrog

  I want to make a little free calendar program to help me and others calculate how much time we have got left in a project. I mean real working time, not just time. Time in a raw form is not saying much. Typically when my boss tells me that I have time until 05-05-2011 it doesn't tell me really how much time I have to do my job. You know...so many things stop me from work: A) beeing at home, not at work (so called "free time" or "spare time"). That is in my case I work exactly 8 hours a day and then the cleaning ladies throw me out of the office with their incredible loud industrial vacuum cleaners every evening (my boss accepts that as an excuse to go home in time, regularly). B) weekends, or more precisely saturdays and sundays C) official holiday rescuing me from having to go to work. what I want to do is make a little utility which tells me how many working hours I really have in a given time period. The first two things A and B are pretty easy to implement. But the last thing C scares my pants off. Holidays. OOOHHH man. You know what that means. Chaos. Pure chaos. The huge question is: HOW TO CALCULATE HOLIDAYS?! Since I want my program to be useful for anyone anywhere in the world, I can't just hardcode all holidays for my little town. So which options do I have? I) I could hand-craft downloadable lists of holidays. Users search them within the application and download them from an webserver. Or I ship all of them in the package. But I would get very, very old if I tried that by myself for every country, state and town. II) I make an initial data sheet with holidays for my town, and don't care about the rest. However, I make that sheet with an how-to public, so that everyone who feels like beeing very nice can provide holiday data for his country / region / whatever. Those are made public on a webserver and everyone can get the data packages he/she needs for the app. III) ? I care a lot about usability. I don't want to make an ugly linux hack style hard to use app that only computer freaks can use. So you need to tell me more about holiday science. I was never really clever at this. I assume every single country in the world has it's own set of holidays. In every country there may be several states. For example the US has some, and Germany has also some states. Holidays vary from state to state. But I know from an good programmer he told me never assume anything. So the questions about holiday science are: Which categories do I need to make holiday-data-packs searchable? A guy from India should find quickly his holiday data pack, and a guy from Sillicon Valley should find his pack as equally fast. It makes most sense to me to filter for COUNTRY STATE WHATEVER. Like a drill-down-search. Did I miss something? What would be the best data format to hold holiday information? A holiday has a start and end date and a name. That should be enough. Would I put all this stuff in thousands of XML files? How would you go about this? Any hint / help is highly welcome! Thanks to everyone!

• Xcode/iPhone Development 6 months in - Annoyances

  - by clearbrian

  Hi I've been iPhone programming for 6 months and come from a PC/Java/Eclipse background and still have a few annoyances with Xcode/iPhone programming I wonder are there any shortcuts to. Is there any way to prevent multiple windows opening all the time in XCode? a) When you click on the Errors/Warnings in the bottom right of the status bar build errors are shown in separate window. Any way to get these to show in the main editor? b) Anyway to get debugger to appear in main editor. I have a big screen iMac and it's still window hell on Macs. When you come from Alt-Tab the Mac is a nightmare. 2) Anyway to get a toolbar item on the main editor to: a) Open Console (I know CMD-thingy-R) b) Open Break points (you have to open Debugger first then breakpoints) I know there's keyboard shortcuts but I have only left hand free others on the trackball so any keys on right hand side of keyboard are too far. I know you can add Finder toolbar scripts (just wondering if anyway to extend Xcode). Are there utilities to extend Xcode? Scripts/Automator/Any Services I can setup to help. Can you automate Xcode like you can with Windows/ActiveX/VBA 3) Limit lookups using CMD + double click. If I double click on a variable to find its definition using CMD + double click it shows every occurrence of all variables with that name. (annoying it you name all you maps mapView) Anyway to get it to limit to the current class or at least order so current class is first. 4) Find doesn't seem to loop backwards if result all above cursor position I'm in a class and I hit CMD + F for find. Find box appears. I enter some text hit return. It says I have x matches but only back arrow is highlight in Find But when I hit < it does nothing. I need to scroll to the top and redo the search. If the text is both forwards and backwards then both < are highlighted and it works. is this a bug or a 'feature' Missing Eclipse features I have been looking at the User Script menu but was wondering how powerful they are? 5) any scripts around to generate source from members such as description: @property @synthesize if I add a new member, run a script will generate @property/@syntesize and release in dealloc 7) any good sites for scripts? SCM Im having problems with SCM and Folders on HD under project Classes directory. You get a library e.g. JSON. It usually comes as a folder. You copy it to the /Classes for your project. /Classes/JSON I create a Group for the Library in Xcode under Classes group. Classes JSON I drag the files from the folder into xcode into the JSON Group. I add them to the SCM and icon changes from ? to A but if I try and commit them it say folder /JSON is not under SCM. Can you drag a folder into Xcode so that it AND its files get included in SCM? Anyway to stop Xcode Help from being on top all the time. I keep feeling like punching it and telling it to get out of the way! :) I dont mind it open just not in the way once I've finished. Yes I know I can Ctrl-W Sites: the main site I use to learn Obj-C are : stackoverflow.com Google code Search - tonnes of full apps on here http://www.iphonedevsdk.com/forum/iphone-sdk-development/ Apple Developers Forums (anyway to get RSS feed to these or is that blasphemy :) ) Safari - 100s of IT book though prob too many to keep up :) any others? Any site that gives simple examples for Obj-C/ UIKit The docs just show the methods but actual examples (Google code search has helped a lot here)

• Custom ProgressBarBrushConverter Not Filling In ProgressBar

  - by Wonko the Sane

  Hello All, I am attempting to create a custom ProgressBarBrushConverter, based on information from here and here. However, when it runs, the progress is not being shown. If I use the code found in the links, it appears to work correctly. Here is the converter in question: public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture) { ProgressBar progressBar = null; foreach (object value in values) { if (value is ProgressBar) { progressBar = value as ProgressBar; break; } } if (progressBar == null) return DependencyProperty.UnsetValue; FrameworkElement indicator = progressBar.Template.FindName("PART_Indicator", progressBar) as FrameworkElement; DrawingBrush drawingBrush = new DrawingBrush(); drawingBrush.Viewport = drawingBrush.Viewbox = new Rect(0.0, 0.0, indicator.ActualWidth, indicator.ActualHeight); drawingBrush.ViewportUnits = BrushMappingMode.Absolute; drawingBrush.TileMode = TileMode.None; drawingBrush.Stretch = Stretch.None; DrawingGroup group = new DrawingGroup(); DrawingContext context = group.Open(); context.DrawRectangle(progressBar.Foreground, null, new Rect(0.0, 0.0, indicator.ActualWidth, indicator.ActualHeight)); context.Close(); drawingBrush.Drawing = group; return drawingBrush; } Here is the ControlTemplate (the MultiBinding is to make sure that the converter is called whenever the Value or IsIndeterminate properties are changed): <ControlTemplate x:Key="customProgressBarTemplate" TargetType="{x:Type ProgressBar}"> <Grid> <Path x:Name="PART_Track" HorizontalAlignment="Left" VerticalAlignment="Top" Stretch="Fill" StrokeLineJoin="Round" Stroke="#DDCBCBCB" StrokeThickness="4" Data="M 20,100 L 80,10 C 100,120 160,140 190,180 S 160,220 130,180 T 120,150 20,100 Z "> <Path.Fill> <MultiBinding> <MultiBinding.Converter> <local:ProgressBarBrushConverter /> </MultiBinding.Converter> <Binding RelativeSource="{RelativeSource FindAncestor, AncestorType={x:Type ProgressBar}}" /> <Binding Path="IsIndeterminate" RelativeSource="{RelativeSource TemplatedParent}"/> <Binding Path="Value" RelativeSource="{RelativeSource TemplatedParent}"/> </MultiBinding> </Path.Fill> <!--<Path.LayoutTransform> <RotateTransform Angle="180" CenterX="190" CenterY="110" /> </Path.LayoutTransform>--> </Path> <Rectangle x:Name="PART_Indicator" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="1" /> </Grid> </ControlTemplate> Finally, the Window code (fairly straightforward - it just animates progress from 0 to 100 and back again): <ProgressBar x:Name="progress" Template="{StaticResource customProgressBarTemplate}" Foreground="Red"> <ProgressBar.Triggers> <EventTrigger RoutedEvent="ProgressBar.Loaded"> <BeginStoryboard x:Name="storyAnimate"> <Storyboard> <DoubleAnimationUsingKeyFrames Duration="0:0:12" AutoReverse="True" FillBehavior="Stop" RepeatBehavior="Forever" Storyboard.TargetName="progress" Storyboard.TargetProperty="(ProgressBar.Value)"> <LinearDoubleKeyFrame Value="0" KeyTime="0:0:0" /> <LinearDoubleKeyFrame Value="100" KeyTime="0:0:5" /> <LinearDoubleKeyFrame Value="100" KeyTime="0:0:6" /> <LinearDoubleKeyFrame Value="0" KeyTime="0:0:11" /> <LinearDoubleKeyFrame Value="0" KeyTime="0:0:12" /> </DoubleAnimationUsingKeyFrames> </Storyboard> </BeginStoryboard> </EventTrigger> </ProgressBar.Triggers> </ProgressBar> I am thinking that the problem is in the DrawRectangle call in the Convert method, but setting a TracePoint on it shows what appear to be valid values for the Rect. What am I missing here? Thanks, wTs

• How do I center a UIImageView within a full-screen UIScrollView?

  - by Sebastian Celis

  In my application, I would like to present the user with a full-screen photo viewer much like the one used in the Photos app. This is just for a single photo and as such should be quite simple. I just want the user to be able to view this one photo with the ability to zoom and pan. I have most of it working. And, if I do not center my UIImageView, everything behaves perfectly. However, I really want the UIImageView to be centered on the screen when the image is sufficiently zoomed out. I do not want it stuck to the top-left corner of the scroll view. Once I attempt to center this view, my vertical scrollable area appears to be greater than it should be. As such, once I zoom in a little, I am able to scroll about 100 pixels past the top of the image. What am I doing wrong? @interface MyPhotoViewController : UIViewController <UIScrollViewDelegate> { UIImage* photo; UIImageView *imageView; } - (id)initWithPhoto:(UIImage *)aPhoto; @end @implementation MyPhotoViewController - (id)initWithPhoto:(UIImage *)aPhoto { if (self = [super init]) { photo = [aPhoto retain]; // Some 3.0 SDK code here to ensure this view has a full-screen // layout. } return self; } - (void)dealloc { [photo release]; [imageView release]; [super dealloc]; } - (void)loadView { // Set the main view of this UIViewController to be a UIScrollView. UIScrollView *scrollView = [[UIScrollView alloc] init]; [self setView:scrollView]; [scrollView release]; } - (void)viewDidLoad { [super viewDidLoad]; // Initialize the scroll view. CGSize photoSize = [photo size]; UIScrollView *scrollView = (UIScrollView *)[self view]; [scrollView setDelegate:self]; [scrollView setBackgroundColor:[UIColor blackColor]]; // Create the image view. We push the origin to (0, -44) to ensure // that this view displays behind the navigation bar. imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0.0, -44.0, photoSize.width, photoSize.height)]; [imageView setImage:photo]; [scrollView addSubview:imageView]; // Configure zooming. CGSize screenSize = [[UIScreen mainScreen] bounds].size; CGFloat widthRatio = screenSize.width / photoSize.width; CGFloat heightRatio = screenSize.height / photoSize.height; CGFloat initialZoom = (widthRatio > heightRatio) ? heightRatio : widthRatio; [scrollView setMaximumZoomScale:3.0]; [scrollView setMinimumZoomScale:initialZoom]; [scrollView setZoomScale:initialZoom]; [scrollView setBouncesZoom:YES]; [scrollView setContentSize:CGSizeMake(photoSize.width * initialZoom, photoSize.height * initialZoom)]; // Center the photo. Again we push the center point up by 44 pixels // to account for the translucent navigation bar. CGPoint scrollCenter = [scrollView center]; [imageView setCenter:CGPointMake(scrollCenter.x, scrollCenter.y - 44.0)]; } - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [[[self navigationController] navigationBar] setBarStyle:UIBarStyleBlackTranslucent]; [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackTranslucent animated:YES]; } - (void)viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated]; [[[self navigationController] navigationBar] setBarStyle:UIBarStyleDefault]; [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault animated:YES]; } - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView { return imageView; } @end

• Recommended ASP.NET Shared Hosting (USA)

  - by coffeeaddict

  Ok, I have to admit I'm getting fed up with www.discountasp.net's pricing model and this annoyance has built up over the past 8 years or so. I've been with them for years and absolutely love them on the technical side, however it's getting ridiculously expensive for so little that you get. I mean here's my scenario: 1) I am running 2 SQL Server databases which costs me $10/ea per month so that's $20/month for 2 and I only get 500 mb disk space which is horrible 2) I am paying $10/mo just for the hosting itself which I only get 1 gig of disk space! I mean common! 3) I am simply running 2 small apps (Screwturn Wiki & Subtext Blog)...so I don't really care if it's up 99% or not, it's not worth paying a total of $300 just to keep these 2 apps running over discountasp.net Anyone else feel the same? Yes, I know they have great support, probably have great servers running behind this but in the end I really don't care as long as my site is up 95% or better. Yes, the hosting toolset rocks. But you know I bet you I can find a similar set somewhere else. I like how I can totally control IIS 7 at discountasp and I can control my own app pool etc. That's very powerful and essential. But anyone have any good alternatives to discountasp that gives me close to the same at a much more reasonable cost point? I mean http://www.m6.net/prices.aspx gives you 10 SQL Databases for $7 and 200 gigs disk space! I don't know about their tools or support but just looking at those numbers and some other hosts I've seen, I feel that discountasp.net is way out of line. They don't even offer any purchasing discounts such as it would be nice if my 2nd SQL Server is only $5/month not $10...stuff like this, to make it much more realistic and fair. Opinions (people who do have discountasp.net, people who have left them, or people who have another host they like)??? But geez $300 just to host a couple DBs and lightweight open source apps? Not worth the price they are charging. I'm almost at a price point that enables me to get a decent dedicated server! I really don't care about beta ASP.NET frameworks support. Not a big deal to me. If you have alternative suggestions rather than your experience with discountasp, I'd like to know how their toolset is. Do you have complete control over your DB in terms of adding users, and same goes for the web app pool, etc.? Discountasp.net's control panel rocks. I don't want to loose the ability to at least control and add virtual directories, recycle my dedicated app pool myself, backup my sql database myself, through tools which is what discountasp does give you. I'd also want to know that the hoster at least gets the latest and greatest in terms of non-beta ASP.NET related frameworks available to its shared hosters.

• ASP.NET: Button in user control not posting back

  - by Ronnie Overby

  I have a simple user control with this code: <%@ Control Language="C#" AutoEventWireup="true" CodeFile="Pager.ascx.cs" Inherits="Pager" %> <table style="width: 100%;"> <tr> <td runat="server" id="PageControls"> <!-- This button has the problem: --> <asp:Button ID="btnPrevPage" runat="server" Text="&larr;" OnClick="btnPrevPage_Click" /> Page <asp:DropDownList runat="server" ID="ddlPage" AutoPostBack="true" OnSelectedIndexChanged="ddlPage_SelectedIndexChanged" /> of <asp:Label ID="lblTotalPages" runat="server" /> <!-- This button has the problem: --> <asp:Button ID="btnNextPage" runat="server" Text="&rarr;" OnClick="btnNextPage_Click" /> </td> <td align="right" runat="server" id="itemsPerPageControls"> <asp:Literal ID="perPageText1" runat="server" /> <asp:DropDownList ID="ddlItemsPerPage" runat="server" AutoPostBack="true" OnSelectedIndexChanged="ddlItemsPerPage_SelectedIndexChanged" /> <asp:Literal ID="perPageText2" runat="server" /> </td> </tr> </table> As you can see, the 2 buttons are wired to click events, which are defined correctly in the code-behind. Now, here is how I include an instance of the control on my page: <uc:Pager ID="Pager1" runat="server" TotalRecords="100" DisplayItemsPerPage="true" ItemsPerPageChoices="10,25,50,100" ItemsPerPageFormatString="Sessions/Page: {0}" PageSize="25" OnPageChanged="PageChanged" OnPageSizeChanged="PageChanged" /> I noticed though, that the 2 buttons in my user control weren't causing a post back when clicked. The drop down list does cause postback, though. Here is the rendered HTML: <table style="width: 100%;"> <tr> <td id="ctl00_MainContent_Pager1_PageControls" align="left"> <!-- No onclick event! Why? --> <input type="submit" name="ctl00$MainContent$Pager1$btnPrevPage" value="?" id="ctl00_MainContent_Pager1_btnPrevPage" /> Page <select name="ctl00$MainContent$Pager1$ddlPage" onchange="javascript:setTimeout('__doPostBack(\'ctl00$MainContent$Pager1$ddlPage\',\'\')', 0)" id="ctl00_MainContent_Pager1_ddlPage"> <option value="1">1</option> <option selected="selected" value="2">2</option> <option value="3">3</option> <option value="4">4</option> <option value="5">5</option> <option value="6">6</option> </select> of <span id="ctl00_MainContent_Pager1_lblTotalPages">6</span> <!-- No onclick event! Why? --> <input type="submit" name="ctl00$MainContent$Pager1$btnNextPage" value="?" id="ctl00_MainContent_Pager1_btnNextPage" /> </td> <td id="ctl00_MainContent_Pager1_itemsPerPageControls" align="right"> Sessions/Page: <select name="ctl00$MainContent$Pager1$ddlItemsPerPage" onchange="javascript:setTimeout('__doPostBack(\'ctl00$MainContent$Pager1$ddlItemsPerPage\',\'\')', 0)" id="ctl00_MainContent_Pager1_ddlItemsPerPage"> <option value="10">10</option> <option selected="selected" value="25">25</option> <option value="50">50</option> <option value="100">100</option> </select> </td> </tr> </table> And, as you can see, there is no onclick attribute being rendered in the button's input elements. Why not?

• Creating a Comment Anchor

  - by John

  Hello, The function below allows a user to insert a comment into a MySQL table called "comment." Then, the file "comments2.php" displays all comments for a given submission. Right after a user submits a comment, I would like the top of the user's browser to be anchored by the comment the user just submitted. How can I do this?

• Is C# slower than VB.NET?

  - by Matt Winckler

  Believe it or not, despite the title, this is not a troll. Running some benchmarks this morning, my colleagues and I have discovered some strange things concerning performance, and I am wondering if we're doing something horribly wrong. We started out comparing C# vs. Delphi Prism calculating prime numbers, and found that Prism was about 30% faster. I figured maybe CodeGear did more optimization when generating IL (the exe was about twice as big as C#'s and had all sorts of different IL in it.) So I decided to write a test in VB.NET as well, assuming that Microsoft's compilers would end up writing essentially the same IL for each language. However, the result there was more shocking: C# was more than three times slower than VB running the same operations. The generated IL was different, but not extremely so, and I'm not good enough at reading it to understand the differences. As a fan of C#, this apparent slowness wounds me horribly, and I am left wondering: what in the world is going on here? Is it time to pack it all in and go write web apps in Ruby? ;-) I've included the code for each below--just copy it into a new VB or C# console app, and run. On my machine, VB finds 348513 primes in about 6.36 seconds. C# finds the same number of primes in 21.76 seconds. (I've got an Intel Core2 Quad Q6600 @2.4Ghz; on another Intel machine in the office the code for both runs much faster but the ratio is about the same; on an AMD machine here the timing is ~10 seconds for VB and ~13 for C#--much less difference, but C# is still always slower.) Both of the console applications were compiled in Release mode, but otherwise no project settings were changed from the defaults generated by Visual Studio 2008. Is it a generally-known fact that C#'s generated IL is worse than VB's? Or is this a strange edge case? Or is my code flawed somehow (most likely)? Any insights are appreciated. VB code Imports System.Diagnostics Module Module1 Private temp As List(Of Int32) Private sw As Stopwatch Private totalSeconds As Double Sub Main() serialCalc() End Sub Private Sub serialCalc() temp = New List(Of Int32)() sw = Stopwatch.StartNew() For i As Int32 = 2 To 5000000 testIfPrimeSerial(i) Next sw.Stop() totalSeconds = sw.Elapsed.TotalSeconds Console.WriteLine(String.Format("{0} seconds elapsed.", totalSeconds)) Console.WriteLine(String.Format("{0} primes found.", temp.Count)) Console.ReadKey() End Sub Private Sub testIfPrimeSerial(ByVal suspectPrime As Int32) For i As Int32 = 2 To Math.Sqrt(suspectPrime) If (suspectPrime Mod i = 0) Then Exit Sub End If Next temp.Add(suspectPrime) End Sub End Module C# Code using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Diagnostics; namespace FindPrimesCSharp { class Program { List<Int32> temp = new List<Int32>(); Stopwatch sw; double totalSeconds; static void Main(string[] args) { new Program().serialCalc(); } private void serialCalc() { temp = new List<Int32>(); sw = Stopwatch.StartNew(); for (Int32 i = 2; i <= 5000000; i++) { testIfPrimeSerial(i); } sw.Stop(); totalSeconds = sw.Elapsed.TotalSeconds; Console.WriteLine(string.Format("{0} seconds elapsed.", totalSeconds)); Console.WriteLine(string.Format("{0} primes found.", temp.Count)); Console.ReadKey(); } private void testIfPrimeSerial(Int32 suspectPrime) { for (Int32 i = 2; i <= Math.Sqrt(suspectPrime); i++) { if (suspectPrime % i == 0) return; } temp.Add(suspectPrime); } } }

• Android: Get the X and Y coordinates of a TextView?

  - by Jep Knopz

  I am working now on a project. I have 2 draggable textView in a circle. I want to add those value inside the circle when the circle is drag over the other circle. the first option that I have is to get the X and Y of the circle, but I get it. Can anyone fix my code? Here is the Code: MainActivity public class MainActivity extends Activity { int windowwidth; int windowheight; TextView bola; TextView bola2; private float x; private float y; private android.widget.RelativeLayout.LayoutParams layoutParams; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); windowwidth = getWindowManager().getDefaultDisplay().getWidth(); windowheight = getWindowManager().getDefaultDisplay().getHeight(); bola = (TextView) findViewById(R.id.ball); bola2 = (TextView) findViewById(R.id.ball2); bola2.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { // TODO Auto-generated method stub layoutParams = (RelativeLayout.LayoutParams) bola2 .getLayoutParams(); switch (event.getActionMasked()) { case MotionEvent.ACTION_DOWN: break; case MotionEvent.ACTION_MOVE: int x_cord = (int) event.getRawX(); int y_cord = (int) event.getRawY(); if (x_cord > windowwidth) { x_cord = windowwidth; } if (y_cord > windowheight) { y_cord = windowheight; } layoutParams.leftMargin = x_cord - 25; layoutParams.topMargin = y_cord - 75; bola2.setLayoutParams(layoutParams); break; default: break; } return true; } }); bola.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { layoutParams = (RelativeLayout.LayoutParams) bola .getLayoutParams(); switch (event.getActionMasked()) { case MotionEvent.ACTION_DOWN: break; case MotionEvent.ACTION_MOVE: int x_cord = (int) event.getRawX(); int y_cord = (int) event.getRawY(); if (x_cord > windowwidth) { x_cord = windowwidth; } if (y_cord > windowheight) { y_cord = windowheight; } layoutParams.leftMargin = x_cord - 25; layoutParams.topMargin = y_cord - 75; bola.setLayoutParams(layoutParams); break; default: break; } // TODO Auto-generated method stub return true; } }); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_main, menu); return true; }} Activity_main.xml <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" > <TextView android:id= "@+id/ball" android:background="@drawable/bgshape" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="1" tools:context=".MainActivity" /> <TextView android:id= "@+id/ball2" android:background="@drawable/bgshape" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="2" tools:context=".MainActivity" android:layout_x="60dp" android:layout_y="20dp" /> The bgshape.xml(for the circle) <?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android" > <padding android:bottom="20dp" android:left="25dp" android:right="25dp" android:top="20dp" /> <stroke android:width="2dp" android:color="#000000" /> <solid android:color="#ffffff" /> <corners android:bottomLeftRadius="30dp" android:bottomRightRadius="30dp" android:topLeftRadius="30dp" android:topRightRadius="30dp" /> This code works well.

• How to manage a MotionEvent going from one View to another?

  - by Darren

  I have a SurfaceView that takes up part of the screen, and some buttons along the bottom. When a button is pressed and the user drags, I want to be able to drag a picture (based on the button) onto the SurfaceView and have it drawn there. I want to be able to use clickListeners and the like, and not just have a giant SurfaceView with me writing code to detect where the user pressed and if it's a button, etc. I have somewhat of a solution, but it seems a bit of a hack to me. What is the best way to accomplish this using the framework intelligently? Part of my XML: <RelativeLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/background"> <!-- Place buttons along the bottom --> <RelativeLayout android:id="@+id/bottom_bar" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="40dip" android:layout_alignParentBottom="true" android:background="@null"> <ImageButton android:id="@+id/btn_1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerVertical="true" android:background="@null" android:src="@drawable/btn_1"> </ImageButton> <!-- More buttons here... --> </RelativeLayout> <!-- Place the SurfaceView in a frame so we can stack on top of it --> <FrameLayout android:layout_width="fill_parent" android:layout_height="0px" android:layout_weight="1" android:layout_above="@id/bottom_bar"> <com.project.question.MySurfaceView android:id="@+id/my_view" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </FrameLayout> And the relevant Java code in MySurfaceView, which extends SurfaceView. mTouchX and Y are used in the onDraw method to draw the image: @Override public boolean onTouchEvent(MotionEvent event){ mTouchX = (int) event.getX(); mTouchY = (int) event.getY(); return true; } public void onButtonTouchEvent(MotionEvent event){ event.setLocation(event.getX(), event.getY() + mScreenHeight); onTouchEvent(event); } Finally, the activity: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.my_surface); mView = (MySurfaceView) findViewById(R.id.my_view); mSurfaceHeight = mView.getHeight(); mBtn = (ImageButton) findViewById(R.id.btn_1); mBtn.setOnTouchListener(mTouchListener); } OnTouchListener mTouchListener = new OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { int [] location = new int[2]; v.getLocationOnScreen(location); event.setLocation(event.getX() + location[0], event.getY()); mView.onButtonTouchEvent(event); return true; } }; Strangely, one has to add to the x-coordinate in the activity, then add to the y coordinate in the View. Otherwise, it doesn't show up in the correct position. If you add nothing, something drawn using mTouchX and mTouchY will show up in the upper left corner of the SurfaceView. Any direction would be greatly appreciated. If I'm going about this completely the wrong way, that would be good information too.

• Code Golf: Finite-state machine!

  - by Adam Matan

  Finite state machine A deterministic finite state machine is a simple computation model, widely used as an introduction to automata theory in basic CS courses. It is a simple model, equivalent to regular expression, which determines of a certain input string is Accepted or Rejected. Leaving some formalities aside, A run of a finite state machine is composed of: alphabet, a set of characters. states, usually visualized as circles. One of the states must be the start state. Some of the states might be accepting, usually visualized as double circles. transitions, usually visualized as directed arches between states, are directed links between states associated with an alphabet letter. input string, a list of alphabet characters. A run on the machine begins at the starting state. Each letter of the input string is read; If there is a transition between the current state and another state which corresponds to the letter, the current state is changed to the new state. After the last letter was read, if the current state is an accepting state, the input string is accepted. If the last state was not an accepting state, or a letter had no corresponding arch from a state during the run, the input string is rejected. Note: This short descruption is far from being a full, formal definition of a FSM; Wikipedia's fine article is a great introduction to the subject. Example For example, the following machine tells if a binary number, read from left to right, has an even number of 0s: The alphabet is the set {0,1}. The states are S1 and S2. The transitions are (S1, 0) -> S2, (S1, 1) -> S1, (S2, 0) -> S1 and (S2, 1) -> S2. The input string is any binary number, including an empty string. The rules: Implement a FSM in a language of your choice. Input The FSM should accept the following input: <States> List of state, separated by space mark. The first state in the list is the start state. Accepting states begin with a capital letter. <transitions> One or more lines. Each line is a three-tuple: origin state, letter, destination state) <input word> Zero or more characters, followed by a newline. For example, the aforementioned machine with 1001010 as an input string, would be written as: S1 s2 S1 0 s2 S1 1 S1 s2 0 S1 s2 1 s2 1001010 Output The FSM's run, written as <State> <letter> -> <state>, followed by the final state. The output for the example input would be: S1 1 -> S1 S1 0 -> s2 s2 0 -> S1 S1 1 -> S1 S1 0 -> s2 s2 1 -> s2 s2 0 -> S1 ACCEPT For the empty input '': S1 ACCEPT For 101: S1 1 -> S1 S1 0 -> s2 s2 1 -> s2 REJECT For '10X': S1 1 -> S1 S1 0 -> s2 s2 X REJECT Prize A nice bounty will be given to the most elegant and short solution. Reference implementation A reference Python implementation will be published soon.

• boost::function & boost::lambda again

  - by John Dibling

  Follow-up to post: http://stackoverflow.com/questions/2978096/using-width-precision-specifiers-with-boostformat I'm trying to use boost::function to create a function that uses lambdas to format a string with boost::format. Ultimately what I'm trying to achieve is using width & precision specifiers for strings with format. boost::format does not support the use of the * width & precision specifiers, as indicated in the docs: Width or precision set to asterisk (*) are used by printf to read this field from an argument. e.g. printf("%1$d:%2$.*3$d:%4$.*3$d\n", hour, min, precision, sec); This class does not support this mechanism for now. so such precision or width fields are quietly ignored by the parsing. so I'm trying to find other ways to accomplish the same goal. Here is what I have so far, which isn't working: #include <string> #include <boost\function.hpp> #include <boost\lambda\lambda.hpp> #include <iostream> #include <boost\format.hpp> #include <iomanip> #include <boost\bind.hpp> int main() { using namespace boost::lambda; using namespace std; boost::function<std::string(int, std::string)> f = (boost::format("%s") % boost::io::group(setw(_1*2), setprecision(_2*2), _3)).str(); std::string s = (boost::format("%s") % f(15, "Hello")).str(); return 0; } This generates many compiler errors: 1>------ Build started: Project: hacks, Configuration: Debug x64 ------ 1>Compiling... 1>main.cpp 1>.\main.cpp(15) : error C2872: '_1' : ambiguous symbol 1> could be 'D:\Program Files (x86)\boost\boost_1_42\boost/lambda/core.hpp(69) : boost::lambda::placeholder1_type &boost::lambda::`anonymous-namespace'::_1' 1> or 'D:\Program Files (x86)\boost\boost_1_42\boost/bind/placeholders.hpp(43) : boost::arg<I> `anonymous-namespace'::_1' 1> with 1> [ 1> I=1 1> ] 1>.\main.cpp(15) : error C2664: 'std::setw' : cannot convert parameter 1 from 'boost::lambda::placeholder1_type' to 'std::streamsize' 1> No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called 1>.\main.cpp(15) : error C2872: '_2' : ambiguous symbol 1> could be 'D:\Program Files (x86)\boost\boost_1_42\boost/lambda/core.hpp(70) : boost::lambda::placeholder2_type &boost::lambda::`anonymous-namespace'::_2' 1> or 'D:\Program Files (x86)\boost\boost_1_42\boost/bind/placeholders.hpp(44) : boost::arg<I> `anonymous-namespace'::_2' 1> with 1> [ 1> I=2 1> ] 1>.\main.cpp(15) : error C2664: 'std::setprecision' : cannot convert parameter 1 from 'boost::lambda::placeholder2_type' to 'std::streamsize' 1> No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called 1>.\main.cpp(15) : error C2872: '_3' : ambiguous symbol 1> could be 'D:\Program Files (x86)\boost\boost_1_42\boost/lambda/core.hpp(71) : boost::lambda::placeholder3_type &boost::lambda::`anonymous-namespace'::_3' 1> or 'D:\Program Files (x86)\boost\boost_1_42\boost/bind/placeholders.hpp(45) : boost::arg<I> `anonymous-namespace'::_3' 1> with 1> [ 1> I=3 1> ] 1>.\main.cpp(15) : error C2660: 'boost::io::group' : function does not take 3 arguments 1>.\main.cpp(15) : error C2228: left of '.str' must have class/struct/union 1>Build log was saved at "file://c:\Users\john\Documents\Visual Studio 2005\Projects\hacks\x64\Debug\BuildLog.htm" 1>hacks - 7 error(s), 0 warning(s) ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ========== My fundamental understanding of boost's lambdas and functions is probably lacking.

• jQuery dynamic field classes not being assigned as desired.

  - by Simon

  Hello, I'm working on a fancy login page with 4 unique states attributed through classes for each field (normal, focus, active-on, active-off). Normal is the default style. Focus is the focus style when nothing is typed. Active-on is the focus style when something has been typed. Active-off is for field that have user text in them, but are not focused right now. Here's a demo to help you understand what I'm doing: http://www.controlstack.com/login My JS is working almost correctly (thanks to some folks on this site), except in 2 cases: If I enter something in the username field, then tab over to the password field, it does not add the ".focus" class to the password field. If I blur out of the username field, then focus back on it, enter a few characters, then delete them, it does not add the ".focus" field. Here's my code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" dir="ltr"> <head> <title>Login</title> <style> input.field {height: 39px; width: 194px; background: url(login-fields.png) no-repeat; overflow: hidden; border: none; outline: none; float: left; margin-right: 7px;} input.field#username {padding: 0 12px;} input.field#username.focus {background-position: 0 -39px;} input.field#username.active-on {background-position: 0 -78px;} input.field#username.active-off {background-position: 0 -117px;} input.field#password {background-position: -218px 0; padding: 0 12px;} input.field#password.focus {background-position: -218px -39px;} input.field#password.active-on {background-position: -218px -78px;} input.field#password.active-off {background-position: -218px -117px;} input.field#go {background-position: -436px 0; width: 88px; margin: 0; cursor: pointer;} </style> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript"> $(document).ready(function() { loginField = $('.field'); firstField = $('.field.first'); firstField.focus(); loginField.focus(function(){ loginVal1 = loginField.val(); if (!loginVal1){ $(this).removeClass('active-off').addClass('focus'); } else { $(this).removeClass('active-off').addClass('active-on'); } }); loginField.live('keydown', function(){ $(this).addClass('active-on').removeClass('active-off'); }).live('keyup', function(){ $(this).toggleClass('active-on', $(this).val() != ''); }) loginField.blur(function(){ loginVal2 = loginField.val(); if (!loginVal2){ $(this).removeClass('focus').removeClass('active-on'); $(this).val(''); } else { $(this).removeClass('focus').removeClass('active-on').addClass('active-off'); } }); }); </script> </head> <body> <h1>Login to your account</h1> <form method="post" action="/"> <fieldset> <input type="text" class="field first focus" id="username" /> <input type="text" class="field" id="password" /> <input type="submit" value="" class="field" id="go" alt="login" title="login" /> </fieldset> </form> </body> </html> Your help is much appreciated!

• Animated background image in a hidden <div> doesn't load or loads not animated

  - by Guanche

  Hello, I have spent the whole day trying to make a script which on "submit" hides the form and shows hidden with animated progress bar. The problem is that Internet Explorer doesn't show animated gif images in hidden divs. The images are static. I visited many websites and found a script which uses: document.getElementById(id).style.backgroundImage = 'url(/images/load.gif)'; Finally, my script works in Internet Explorer, Firefox, Opera but... Google Chrome doesn't display the image at all. I see only div text. After many tests I discovered the following: the only way to see the background image in Google Chrome is to include the same image somewhere in the page (outside of hidden div) with 1px dimensions: <img src="/images/load.gif" width="1" heigh="1" /> This did the trick but... after this dirty solution Microsoft Explorer for some reason shows the image as static again. So, my question is: is there any way how to force Gogle Chrome to show the image? Thanks. This is my script: <script language="JavaScript" type="text/javascript"> function ver (id, elementId){ if (document.getElementById('espera').style.visibility == "visible") { return false; }else{ var esplit = document.forms[0]['userfile'].value.split("."); ext = esplit[esplit.length-1]; if (document.forms[0]['userfile'].value == '') { alert('Please select a file'); return false; }else{ if ((ext.toLowerCase() == 'jpg')) { document.getElementById(id).style.position = 'absolute'; document.getElementById(id).style.display = 'inline'; document.getElementById(id).style.visibility = "visible"; document.getElementById(id).style.backgroundImage = 'url(/images/load.gif)'; document.getElementById(id).style.height = "100px"; document.getElementById(id).style.backgroundColor = '#f3f3f3'; document.getElementById(id).style.backgroundRepeat = "no-repeat"; document.getElementById(id).style.backgroundPosition = "50% 50%"; var element; if (document.all) element = document.all[elementId]; else if (document.getElementById) element = document.getElementById(elementId); if (element && element.style) element.style.display = 'none'; return true; }else{ alert('This is not a jpg file'); return false; } } } } </script> <div id="frmDiv"> <form enctype="multipart/form-data" action="/upload.php" method="post" name="upload3" onsubmit="return ver('espera','frmDiv');"> <input type="hidden" name="max_file_size" value="4194304" /> <table border="0" cellspacing="1" cellpadding="2" width="100%"> <tr bgcolor="#f5f5f5"> <td>File (jpg)</td> <td> <input type="file" name="userfile" class="upf" /></td></tr> <tr bgcolor="#f5f5f5"> <td>&nbsp;</td> <td> <input class="upf2" type="submit" name="add" value="Upload" /> </td></tr></table></form> </div> <div id="espera" style="display:none;text-align:center;float:left;width:753px;">&nbsp;<br />&nbsp;<br />&nbsp;<br />&nbsp;<br /> &nbsp;<br />Please wait...<br />&nbsp; </div>

• Error Handling without Exceptions

  - by James

  While searching SO for approaches to error handling related to business rule validation , all I encounter are examples of structured exception handling. MSDN and many other reputable development resources are very clear that exceptions are not to be used to handle routine error cases. They are only to be used for exceptional circumstances and unexpected errors that may occur from improper use by the programmer (but not the user.) In many cases, user errors such as fields that are left blank are common, and things which our program should expect, and therefore are not exceptional and not candidates for use of exceptions. QUOTE: Remember that the use of the term exception in programming has to do with the thinking that an exception should represent an exceptional condition. Exceptional conditions, by their very nature, do not normally occur; so your code should not throw exceptions as part of its everyday operations. Do not throw exceptions to signal commonly occurring events. Consider using alternate methods to communicate to a caller the occurrence of those events and leave the exception throwing for when something truly out of the ordinary happens. For example, proper use: private void DoSomething(string requiredParameter) { if (requiredParameter == null) throw new ArgumentExpcetion("requiredParameter cannot be null"); // Remainder of method body... } Improper use: // Renames item to a name supplied by the user. Name must begin with an "F". public void RenameItem(string newName) { // Items must have names that begin with "F" if (!newName.StartsWith("F")) throw new RenameException("New name must begin with /"F/""); // Remainder of method body... } In the above case, according to best practices, it would have been better to pass the error up to the UI without involving/requiring .NET's exception handling mechanisms. Using the same example above, suppose one were to need to enforce a set of naming rules against items. What approach would be best? Having the method return a enumerated result? RenameResult.Success, RenameResult.TooShort, RenameResult.TooLong, RenameResult.InvalidCharacters, etc. Using an event in a controller class to report to the UI class? The UI calls the controller's RenameItem method, and then handles an AfterRename event that the controller raises and that has rename status as part of the event args? The controlling class directly references and calls a method from the UI class that handles the error, e.g. ReportError(string text). Something else... ? Essentially, I want to know how to perform complex validation in classes that may not be the Form class itself, and pass the errors back to the Form class for display -- but I do not want to involve exception handling where it should not be used (even though it seems much easier!) Based on responses to the question, I feel that I'll have to state the problem in terms that are more concrete: UI = User Interface, BLL = Business Logic Layer (in this case, just a different class) User enters value within UI. UI reports value to BLL. BLL performs routine validation of the value. BLL discovers rule violation. BLL returns rule violation to UI. UI recieves return from BLL and reports error to user. Since it is routine for a user to enter invalid values, exceptions should not be used. What is the right way to do this without exceptions?

Thats just a portion of the div, my question is How can I show that DIV in a jquery overlay without loosing its functionallity? i'm asking because i manage to get it working but when i do a "that-div-postback" the screen loses the DIV and keeps only the background of the overlay. a couple more information: <button class="modalInput button" rel="#prompt"> Buscar</button> <script type="text/javascript"> function pageLoad() { var triggers = $("button.modalInput").overlay({ // some expose tweaks suitable for modal dialogs expose: { color: '#333', loadSpeed: 200, opacity: 0.3, zIndex: 99 }, top: '25%', closeOnClick: true }); } </script> Thanks in advance ;)

• Is JQuery UI meant to work only with Google Chrome??? (How about IE and Firefox??!)

  - by Richard77

  Hello, I'm using "Jquery UI 1./Dan Wellman/Packt Publishing" to learn JQuery UI. I'm working on the 'Dialog widget' chapiter. After I've completed a series of exercises in order to build a Dialog widget (using Google Chrome), I then tried my work with Internet Explorer and Firefox. The result has been disappointing. Chrome was perfet With Internet Explorer, (1) the title of the Dialog widget did not appear, (2) The location of the dialog widget was not correct (given the position: ["center", "center"]). It was rather offset toward left. With Firefox, the location was respected. However, only the outer container was visible. the content was missing, just a blank container. Also using Option Show:true and Hide:true did only work with Chrome. I wonder now if JQuery UI was meant to be used only with Google Chrome. I just think that I might be missing some directives to make it work with major browsers (as the author claimed in his book). Here's the code. Since, I'm using ASP.NET MVC, certain codes, such as the element to the css, do not appear. But, for the rest, all the functioning code is bellow. <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <p> The goal of this tutorial is to explain one method of creating model classes for an ASP.NET MVC application.
