  • iphone sdk conditional in switch function

    - by Oliver
    I'm trying to make a random image appear on the press of a button. So it generates a random number, and the switch algorithm swaps the chosen image with the one in the imgview. but I want a switch in the settings app to toggle which set of images to use. I know pretty much how to do it...it's just that it doesn't work. I'm missing some syntax thing...Please help, stackoverflow? it's my birthday. int Number = rand() %30; NSString *toggleValue = [[NSUserDefaults standardUserDefaults] stringForKey:@"enabled_preference"]; switch (Number) { if (*toggleValue == 0) { case 0: picture.image = [UIImage imageNamed:@"1.png"]; break; case 1: picture.image = [UIImage imageNamed:@"2.png"]; break;} else { case 0: picture.image = [UIImage imageNamed:@"3.png"]; break; case 1: picture.image = [UIImage imageNamed:@"4.png"]; break;} }

  • How do I compete the transformation matrix needed to transform a rectangle into a trapezium?

    - by Rich Bradshaw
    I'm playing around with css transforms and the equivalent filters in IE, and want to simulate perspective by transforming a 2d rectangle into a trapezium. Specifically, I want the right hand side of the rectangle to stay the same height, and the left hand side to be say 80% of the height, so that the mid points of both sides are horizontally in line with each other. I'm familiar with matrix algebra, but can't think how to determine what matrix will do that.

  • Generate vCard from AddressBook.framework

    - by Oliver
    I'm utilising the AddressBook.framework in my iPhone app, and I'd like to replicate something along the lines of the share feature in Contacts.app. This basically attach's a specific contacts vCard to an email. As far as I know, there is nothing in the documentation that mentions generating a vCard. Is this a case of generating one myself? Or is there something available that can help me?

  • Objective-C : enum like Java (int values and many others for each enum)

    - by Oliver
    In Java, you can make an enum having multiples values. In objective-C, this cannot be done easily. I've read many pages about this but I didn't found anything satisfying that would allow me to use enums by a simple way and to keep the enum declaration and their different values in the same file. I would like to write something like this in a enums.h : // ======================================== typedef enum {eRED, eGREEN, eBLUE} ColorEnum; int colorValues[] = { 0xFF0000, 0x00FF00, 0x0000FF }; NSArray *colorNames = [NSArray arrayWithObjects:@"Red color", @"light green", @"Deep blue", nil]; // ======================================== and be able to use thoses global variables to manage my stuff anywhere like : int color = colorValues[eRED]; But I don't know how to write this. I have compile errors like "ColorValues" is defines many times. Or if I just use "static", I have many "ColorValues" not used in .m file... Could you help me ?

  • How to make awkward pivot of sql table in MS SQL Server 2005?

    - by Oliver
    I have to rotate a given table from an sql server but a normal pivot just doesn't work (as far as i tried). So has anybody an idea how to rotate the table into the desired format? Just to make the problem more complicated, the list of given labels can vary and it is possible that a new label name can come into at any given time. Given Data ID | Label | Numerator | Denominator | Ratio ---+-----------------+-------------+---------------+-------- 1 | LabelNameOne | 41 | 10 | 4,1 1 | LabelNameTwo | 0 | 0 | 0 1 | LabelNameThree | 21 | 10 | 2,1 1 | LabelNameFour | 15 | 10 | 1,5 2 | LabelNameOne | 19 | 19 | 1 2 | LabelNameTwo | 0 | 0 | 0 2 | LabelNameThree | 15 | 16 | 0,9375 2 | LabelNameFive | 19 | 19 | 1 2 | LabelNameSix | 17 | 17 | 1 3 | LabelNameOne | 12 | 12 | 1 3 | LabelNameTwo | 0 | 0 | 0 3 | LabelNameThree | 11 | 12 | 0,9167 3 | LabelNameFour | 12 | 12 | 1 3 | LabelNameSix | 0 | 1 | 0 Wanted result ID | ValueType | LabelNameOne | LabelNameTwo | LabelNameThree | LabelNameFour | LabelNameFive | LabelNameSix ---+-------------+--------------+--------------+----------------+---------------+---------------+-------------- 1 | Numerator | 41 | 0 | 21 | 15 | | 1 | Denominator | 10 | 0 | 10 | 10 | | 1 | Ratio | 4,1 | 0 | 2,1 | 1,5 | | 2 | Numerator | 19 | 0 | 15 | | 19 | 17 2 | Denominator | 19 | 0 | 16 | | 19 | 17 2 | Ratio | 1 | 0 | 0,9375 | | 1 | 1 3 | Numerator | 12 | 0 | 11 | 12 | | 0 3 | Denominator | 12 | 0 | 12 | 12 | | 1 3 | Ratio | 1 | 0 | 0,9167 | 1 | | 0

  • Adding a ServiceReference programmatically during async postback

    - by Oliver
    Is it possible to add a new ServiceReference instance to the ScriptManager on the Page during an asynchronous postback so that subsequently I can use the referenced web service through client side script? I'm trying to do this inside a UserControl that sits inside a Repeater, that's why adding the ScriptReference programmatically during Page_Load does not work here. EDIT 2: This is the code I call from my UserControl which does not do what I expect (adding the ServiceReference to the ScriptManager during the async postback): private void RegisterWebservice(Type webserviceType) { var scm = ScriptManager.GetCurrent(Page); if (scm == null) throw new InvalidOperationException("ScriptManager needed on the Page!"); scm.Services.Add(new ServiceReference("~/" + webserviceType.Name + ".asmx")); } My goal is for my my UserControl to be as unobtrusive to the surrounding application as possible; otherwise I would have to statically define the ServiceReference in a ScriptManagerProxy on the containing Page, which is not what I want. EDIT: I must have been tired when I wrote this post... because I meant to write ServiceReference not ScriptReference. Updated the text above accordingly. Now I have: <asp:ScriptManagerProxy runat="server" ID="scmProxy"> <Services> <asp:ServiceReference Path="~/UsefulnessWebService.asmx" /> </Services> </asp:ScriptManagerProxy> but I want to register the webservice in the CodeBehind.

  • How to terminate a particular Azure worker role instance

    - by Oliver Bock
    Background I am trying to work out the best structure for an Azure application. Each of my worker roles will spin up multiple long-running jobs. Over time I can transfer jobs from one instance to another by switching them to a readonly mode on the source instance, spinning them up on the target instance, and then spinning the original down on the source instance. If I have too many jobs then I can tell Azure to spin up extra role instance, and use them for new jobs. Conversely if my load drops (e.g. during the night) then I can consolidate outstanding jobs to a few machines and tell Azure to give me fewer instances. The trouble is that (as I understand it) Azure provides no mechanism to allow me to decide which instance to stop. Thus I cannot know which servers to consolidate onto, and some of my jobs will die when their instance stops, causing delays for users while I restart those jobs on surviving instances. Idea 1: I decide which instance to stop, and return from its Run(). I then tell Azure to reduce my instance count by one, and hope it concludes that the broken instance is a good candidate. Has anyone tried anything like this? Idea 2: I predefine a whole bunch of different worker roles, with identical contents. I can individually stop and start them by switching their instance count from zero to one, and back again. I think this idea would work, but I don't like it because it seems to go against the natural Azure way of doing things, and because it involves me in a lot of extra bookkeeping to manage the extra worker roles. Idea 3: Live with it. Any better ideas?

  • Console-like control that allows full control over individual text formatting

    - by Rich.Carpenter
    I'm tinkering with writing a simple text-based role-playing game. I would like to use WinForms, and utilize WinForm controls for the UI and simple text for the output. The catch is, I would like to have complete control over the formatting of the individual text - some words being different colors, etc. A simple console control would suffice, as that would provide control over text colors, but it would be nice to also be able to change style, font and size. Less important: it would be nice to have complete control over where text appears in the control through a coordinate system, as with DOS windows of old. I'd appreciate suggestions on the best method of implementing this. Perhaps there is a better method I had not considered for rendering the output of a text-based game.

  • What's the standard algorithm for syncing two lists of objects?

    - by Oliver Giesen
    I'm pretty sure this must be in some kind of text book (or more likely in all of them) but I seem to be using the wrong keywords to search for it... :( A common task I'm facing while programming is that I am dealing with lists of objects from different sources which I need to keep in sync somehow. Typically there's some sort of "master list" e.g. returned by some external API and then a list of objects I create myself each of which corresponds to an object in the master list. Sometimes the nature of the external API will not allow me to do a live sync: For instance the external list might not implement notifications about items being added or removed or it might notify me but not give me a reference to the actual item that was added or removed. Furthermore, refreshing the external list might return a completely new set of instances even though they still represent the same information so simply storing references to the external objects might also not always be feasible. Another characteristic of the problem is that both lists cannot be sorted in any meaningful way. You should also assume that initializing new objects in the "slave list" is expensive, i.e. simply clearing and rebuilding it from scratch is not an option. So how would I typically tackle this? What's the name of the algorithm I should google for? In the past I have implemented this in various ways (see below for an example) but it always felt like there should be a cleaner and more efficient way. Here's an example approach: Iterate over the master list Look up each item in the "slave list" Add items that do not yet exist Somehow keep track of items that already exist in both lists (e.g. by tagging them or keeping yet another list) When done iterate once more over the slave list Remove all objects that have not been tagged (see 4.) Update Thanks for all your responses so far! I will need some time to look at the links. Maybe one more thing worthy of note: In many of the situations where I needed this the implementation of the "master list" is completely hidden from me. In the most extreme cases the only access I might have to the master list might be a COM-interface that exposes nothing but GetFirst-, GetNext-style methods. I'm mentioning this because of the suggestions to either sort the list or to subclass it both of which is unfortunately not practical in these cases unless I copy the elements into a list of my own and I don't think that would be very efficient. I also might not have made it clear enough that the elements in the two lists are of different types, i.e. not assignment-compatible: Especially, the elements in the master list might be available as interface references only.

  • How to find the first declaring method for a reference method

    - by Oliver Gierke
    Suppose you have a generic interface and an implementation: public interface MyInterface<T> { void foo(T param); } public class MyImplementation<T> implements MyInterface<T> { void foo(T param) { } } These two types are frework types. In the next step I want allow users to extend that interface as well as redeclare foo(T param) to maybe equip it with further annotations. public interface MyExtendedInterface extends MyInterface<Bar> { @Override void foo(Bar param); // Further declared methods } I create an AOP proxy for the extended interface and intercept especially the calls to furtherly declared methods. As foo(…) is no redeclared in MyExtendedInterface I cannot execute it by simply invoking MethodInvocation.proceed() as the instance of MyImplementation only implements MyInterface.foo(…) and not MyExtendedInterface.foo(…). So is there a way to get access to the method that declared a method initially? Regarding this example is there a way to find out that foo(Bar param) was declared in MyInterface originally and get access to the accoriding Method instance? I already tried to scan base class methods to match by name and parameter types but that doesn't work out as generics pop in and MyImplementation.getMethod("foo", Bar.class) obviously throws a NoSuchMethodException. I already know that MyExtendedInterface types MyInterface to Bar. So If I could create some kind of "typed view" on MyImplementation my math algorithm could work out actually.

  • Android custom view - setting it to take up max space available but no more

    - by Rich
    I have a custom View class in my app that I'm using in xml layouts. Wherever I'm using this view in my xml, I don't want it to stretch it's container, but I want it to fill out whatever space is available. Here's an example to make it a little clearer. I have a LinearLayout set to horizontal orientation with my custom view followed by a TextView. The TextView is going to stretch the LinearLayout so that it takes up the space it needs and no more. I want my custom view to take up the vertical space that the TextView has made available. Let's say the TextView ends up being 50px tall because of it's contents. The LinearLayout is thus stretched to about this height (not taking into account any margins or padding), so I just want the view to know it can stretch to that height and not "push on" its container. Without overriding and of the measurement methods of the base class (onMeasure, etc) my View is actually stretching to take up as much space as possible. I have already played around with wrap_content and fill_parent a bunch, so I'm assuming I need to do something in one of the View class' measure methods.

  • MS SQL Server BEGIN/END vs BEGIN TRANS/COMMIT/ROLLBACK

    - by Rich
    I have been trying to find info on the web about the differences between these statements, and it seems to me they are identical but I can't find confirmation of that or any kind of comparison between the two. What is the difference between doing this: BEGIN -- Some update, insert, set statements END and doing this BEGIN TRANS -- Some update, insert, set statements COMMIT TRANS ? Note that there is only the need to rollback in the case of some exception or timeout or other general failure, there would not be a conditional reason to rollback.

  • Return order of MySQL SHOW COLUMNS

    - by rich
    Hey guys. Simple one this, but one I can't seem to find any information on so here goes. I need to find the columns in a specific table, which is no problem.... SHOW COLUMNS FROM tablename LIKE '%ColumnPrefix%'; But I need to know what order they will be returned, preferable by choosing to order the results ascending alphabetically. I have had no luck with using ORDER BY Field. Any ideas? Cheers!

  • Is there a standard way to encode a .NET string into javascript string for use in MS AJAX?

    - by Rich Andrews
    I'm trying to pass the output of a SQL Server exception to the client using the RegisterStartUpScript method of the MS ScriptManager. This works fine for some errors but when the exception contains single quotes the alert fails. I dont want to only escape single quotes though - Is there a standard function i can call to escape any special chars for use in Javascript? string scriptstring = "alert('" + ex.Message + "');"; ScriptManager.RegisterStartupScript(this, this.GetType(), "Alert", scriptstring , true); Thanks tpeczek, the code almost worked for me :) but with a slight amendment (the escaping of single quotes) it works a treat. I've included my amended version here... public class JSEncode { /// <summary> /// Encodes a string to be represented as a string literal. The format /// is essentially a JSON string. /// /// The string returned includes outer quotes /// Example Output: "Hello \"Rick\"!\r\nRock on" /// </summary> /// <param name="s"></param> /// <returns></returns> public static string EncodeJsString(string s) { StringBuilder sb = new StringBuilder(); sb.Append("\""); foreach (char c in s) { switch (c) { case '\'': sb.Append("\\\'"); break; case '\"': sb.Append("\\\""); break; case '\\': sb.Append("\\\\"); break; case '\b': sb.Append("\\b"); break; case '\f': sb.Append("\\f"); break; case '\n': sb.Append("\\n"); break; case '\r': sb.Append("\\r"); break; case '\t': sb.Append("\\t"); break; default: int i = (int)c; if (i < 32 || i > 127) { sb.AppendFormat("\\u{0:X04}", i); } else { sb.Append(c); } break; } } sb.Append("\""); return sb.ToString(); } } As mentioned below - original source: here

  • Can I migrate from ClearCase to Serena VM?

    I have a repository using Rational ClearCase Explorer 2003.06.10+ which I want to migrate into Serena ChangeMan Version Manager 8.1.4.2. Is this possible? The ClearCase repository was not used for all it's functions, just as a place to hold copies of documents, so the only thing I need to keep is the files and their version histories.

  • ASP.Net Problem with Event Handlers and Control Creation Timing

    - by Oliver Weichhold
    What I am trying to achieve here is to display a number of LinkButtons in a RadGrid Column. The buttons are generated from a collection property member of the bound grid row item. The CollectionLinkButton control is nothing more than a asp:Panel derived control that populates its Child Controls from "DataItem.SomeCollection" and this is working fine. The problem I am facing is with this part: Collection='<%# DataBinder.Eval(Container, "DataItem.SomeCollection") %' This is because databound Collection Property is populated so late in the lifecycle of the page that the LinkButton Controls that the CollectionLinkButton class creates from the collection are not available yet during Postback when the Click event Handler is supposed to fire and I have currently no idea how to solve this problem. <radG:RadGrid ID="grid" runat="server" DataSourceID="ds_AB"> <MasterTableView> <Columns> <radG:GridTemplateColumn> <ItemTemplate> <local:CollectionLinkButton ID="LinkButton1" runat="server" CssClass="EntityLinkButton" Collection='<%# DataBinder.Eval(Container, "DataItem.SomeCollection") %>' CollectionProperty="Id" CollectionDisplayProperty="Name" Text='<%# DataBinder.Eval(Container, "DataItem.Name") %>'</local:CollectionLinkButton> </ItemTemplate> </radG:GridTemplateColumn>

  • Having a different action for each button dynamically created in a loop

    - by Oliver
    Hi, use this website a lot but first time posting. My program creates a number of buttons depending on the number of records in a file. E.g. 5 records, 5 buttons. The buttons are being created but i'm having a problem with the action listener. If add the action listener in the loop every button does the same thing; but if I add the action listener outside the loop it just adds the action listener to last button. Any ideas? Here is what I have code-wise (I've just added the for loop to save space): int j=0; for(int i=0; i<namesA.size(); i++) { b = new JButton(""+namesA.get(i)+""); conPanel.add(b); conFrame.add(conPanel); b.addActionListener(new ActionListener(){ public void actionPerformed(ActionEvent ae2){ System.out.println(namesA.get(j)); } }}); j++; } Much Appreciated

  • how to programatically determine Bluetooth master/slave roles?

    - by Rich
    So in a bluetooth piconet, there is one master with upto seven slaves. The master sets the clock and frequency hop that the slaves sync with. But is there a way to determine which device is the master and which is the slave?

  • Android: Deciding between SurfaceView and OpenGL (GLSurfaceView)

    - by Rich
    Is there a way to decide up front based on the expected complexity of a game/app in the planning phase whether to use regular Canvas drawing in a SurfaceView or to go with OpenGL? I've been playing around with a Canvas and only need 2D movement, and on a fairly new phone I'm getting pretty decent performance with a bunch of primitive objects and a few bitmaps running around the screen on a solid background. Is it fair to say that if I'm going to be drawing background images and increasing the number of objects being moved and drawn on top of them that I should go straight to OpenGL?

  • Syncing with Address Book: Last modified property in ABPerson/ABRecord

    - by Oliver
    I'm syncing data from the Address Book into a Core Data database and I've nearly got it working perfectly. The only issue remaining is checking for changes and modifications on startup and reflecting the changes inside Core Data. Currently, I simply check the ID of each ABRecord and see if it is already in Core Data. Of course, this only works in the case of new contacts and not changed information inside an existing contact. One solution would be to go through each contact already in the database and check each property against the Address Book. The down side of this is that it's really slow. One method that would work is if the ABRecord had a last modified date. I could then store the date inside the Core Data database and check on startup to see if I need to update the contact. However, I can't find anything like this in the documentation. Any ideas?
