• Optimising Androidplot

  - by Zammbi

  Seems Androidplot (androidplot.com) website/forums are down so I'll try asking this question here. I have multi touch zoom and scrolling. Similar code to http://mlepicki.com/2012/03/androidplot-multitouch-zoom-scroll/ except that I have a bar graph instead. However with 100 data points it has noticeable lag. Even with 10 bars are just showing. Sounds like its drawing/calculating/etc all bars. Any idea on how I could optimise this? I can't use hardware rendering as I want to support Android 2.1 and the library doesn't support it(it breaks).

• Looking for a good C++/.net book

  - by Michael Minerva

  I have recently started to feel that I need to greatly improve my C++ skills especially in the realm of .net. I graduated from a good four year university with a degree in computer science about 9 months ago and I have since been doing full time contract work for a small software company in my local area. Most of my work has been done using Java/lisp/cocoa/XML and before that most of my programming in my senior year was in java/C#. I did a decent amount of C++ in my Sophomore year and in my free time before that but I feel that my general knowledge of C++/.net is very lacking for the opportunities that are now coming my way. Can anyone recommend a good book that could help me get up too speed? I feel I do not need a very basic introduction to C++ but something that covers the fundamentals of .net would be good for me. So basically what I need is a book or books that would be good for a .net novice and a C++ developer who is just beyond novice. Also, a book that would help bein an interview by giving me a conversional understanding of C++ would be great. Thanks a lot!.

• Restricting deletion with NHibernate

  - by FrontSvin

  I'm using NHibernate (fluent) to access an old third-party database with a bunch of tables, that are not related in any explicit way. That is a child tables does have parentID columns which contains the primary key of the parent table, but there are no foreign key relations ensuring these relations. Ideally I would like to add some foreign keys, but cannot touch the database schema. My application works fine, but I would really like impose a referential integrity rule that would prohibit deletion of parent objects if they have children, e.i. something similar 'ON DELETE RESTRICT' but maintained by NHibernate. Any ideas on how to approach this would be appreciated. Should I look into the OnDelete() method on the IInterceptor interface, or are there other ways to solve this? Of course any solution will come with a performance penalty, but I can live with that.

• iPhone SKD make the iPod controller appear

  - by nico

  Hi all, It's been a while I'm consulting stackoverflow, but this time I didn't find any answer :( My question is quite simple :) On an iPhone/iPod touch, play music. Double tap the home button while the music is playing. You will see appear a popup with the play/pause/next/previous buttons and a volume control. Do you know if it's possible to make this popup appear programmatically ? I mean, I would like to add a button in my app that will display the popup, avoiding the user to double tap the home button (most of them doesn't know this shortcut). Thank you in advance !

• How to get a 3D picture in an iphone app?

  - by wolverine

  In an application, i saw that they used to display pictures of vehicles. But what was amazing was when we touch and swipe in that picture, it rotates in 3d way left and right. And from the front view we can rotate and get to see its back view also. It is a very good feature and i was trying to replicate it. But couldnt get an idea of how and where to start. My doubts are Whats the actual format of the thing, it surely isn't a picture. How do they get to rotate it? Could someone give me an idea where i should start or where I should look upon?

• Develop iPhone application remotely?

  - by ANE

  4 java developers are new to iPod Touch/iPhone app development. They have an idea for an app. They have never used Xcode or Macs before. Instead of spending money for a new iMac or Mac Mini for each of them, my boss would like to sell them a $999 Apple server, hosted at a facility connected a single T1 line, and have all 4 people work remotely in Xcode. Is this feasible? Is anyone doing anything like this? Specifically, is 1 T1 enough for realistic remote app development? Would they have to work in black & white via Logmein or Gotomeeting to get decent speed? Can four people work remotely together on an Xcode project at the same time? Do they absolutely need their own Macs to connect their iPod Touches or iPhones physically to, or can they connect to their existing PCs with iTunes and install their in-development apps that way?

• Determine if a subview is visible in a UIScrollView

  - by Jools

  Hi all, I've added a view to my app, that contains a UIScrollView, with a number of UITextViews in it's content view. This works perfectly on OS 3.0 and up, but when I test it on my 2.2.1 iPod touch, there is a UITextView bug that stops any text views automatically updating their content when they are scrolled into view - so you have to send them the setNeedsDisplay message. However, I only want to do this when they start to become visible during the scroll - how do I determine, in the UIScrollView's scrollViewDidScroll delegate method, whether a UITextView is visible in the UIScrollView's frame? Ta. Jools.

• Delete/move a UITableView row that's attached to a web service.

  - by Kevin L.

  Deleting or moving rows for a UITableView that is backed with local data (e.g., NSArray) is easy and instantaneous: Remove the value from the array. Call deleteRowsAtIndexPaths:withRowAnimation:. Profit! But my table view communicates with a web service, which means once the "Delete" button on that row gets tapped, I have to forward a request on to the server (via ASIHTTPRequest, of course), get the response, and then tell the table view to run its little delete-row animation, all with a few seconds of latency in between. From a high-level, what's the best way to do that? Throw some callback selector into ASIHTTPRequest's userInfo dictionary? KVO? Bonus points for some nice UI touch, like some kind of spinner on the soon-to-be-deleted cell.

• touchesEnded:withEvent: from UIScrollView First Responder

  - by Matthew Mitchell

  I've made a UIScrollView the first responder. I need to maintain touch events to a touchesEnded:withEvent: method on a view behind it. I've tried using the nextResponder method and that failed. I've tried forwarding touchesEnded:withEvent to the view behind it and that fails. How do I get this to work? The UIScrollView wont work unless it is the first responder or gets events some other way. Thank you for any help. Shame Apple's documentation and APIs are terrible in areas.

• Objective C: Using UIImage for Stroking

  - by SeongHo

  I am trying to apply a texture for my brush but i'm really having a hard time figuring how it is done. Here's the image of my output. I used an UIImage that just follows the touch on the screen but when i swipe it faster the result is on the right side "W", and on the left side that's the result when i swipe it slow. i tried using the CGContextMoveToPoint and CGContextAddLineToPoint i don't know how apply the texture. Is it possible to use UIImage for the stroke texture? Here's my code UIImage * brushImageTexture = [UIImage imageNamed:@"brushImage.png"]; [brushImagetexture drawAtPoint:CGPointMake(touchCurrentPosition.x, touchVurrentPosition.y) blendMode:blendMode alpha:1.0f];

• Safe ASCII char to replace whitespace before storing

  - by AngryWhenHungry

  My code passes a big bunch of text data to a legacy lib, which is responsible for storing it. However, it tends to remove trailing whitespace. This is a problem when I read the data back. Since I cannot change the legacy code, I thought about replacing the all spaces with some uncommon ASCII character. When I read back the text, I can replace them back. Is this a bad idea, considering that I cannot touch the legacy storage code? Which character can I use as a substitute? I was considering some char upwards of 180. There will only be spaces - no tabs or newlines - in the data. The data is alphanumeric, with special characters.

• Google Adword not working /conversion.js not found

  - by Jed

  I'm currently working on a wordpress site. My task is just to add the conversion script in a thankyou page. I added the script here: http://www.livingedge.co.nz/thanks-for-getting-in-touch/ , unfortunately does not work. It says that a conversion.js was not found. See the attached screenshot: http://screencast.com/t/52ixQUzHKNxZ I added the conversion script on the footer put it in a conditional so that it will load only on the thakyoupage. I'm new to this and can't figure out what would be the possible cause of such problem. I tried adding the script in the header, on the page editor, on a form redirect. Q: What could be the possible cause of this issue?

• How to open an html file using the default file handler and to give the window a name (i.e. target)?

  - by paul

  I am writing a warm-up script for a SharePoint server. The idea is to call stsadm and then open an html file containing iframes which touch all the key web pages in my portal. So far so good. The problem is that each time the script is run, a new browser window is opened and I end up with a screen full of browsers. The first idea was to close the browser after 10 minutes or so. This would be easy to do except that Javascript is disabled when an html file is opened from the file system. I then thought I might be able to open the file and set it in a named window (target) which would be reused each time the script runs but I haven't found any way to do this. Does anyone have any ideas? Either to force JS to run or to set the window name or another solution? Thanks.

• When iterating over values, why does typeof(value) return "string" when value is a number? Javascrip

  - by Mark

  I'm using Google Chrome for this test: Contrary to intuition, the first loop alerts "string" 3 times, while the second loop alerts "number" 3 times. numarray = [1, 2, 3]; //for-each loop for(num in numarray) alert(typeof(num)); //standard loop for(i=0; i<numarray.length; i++) alert(typeof(numarray[i])); I was expecting both loops to alert "number" 3 times. How is the first loop implemented in Javascript? In other words, if the for-each is syntactic sugar, what is its equivalent using a standard loop? Also, is there some way to iterate over an object's namespace using a standard loop? I'm looking to touch every one of some object's methods and attributes using a loop of the second kind. I'm new to Javascript and any help is highly appreciated, thanks.

• Android: Communication with host computer

  - by dannyn382

  I am looking for ideas as to how all of you can think to solve this issue. I am going to be using an Android Tablet as basically a touch screen input for a project. I need to be able to control servos and solenoids and such, so I will be using a Raspberry Pi to do this. I am looking for ideas on how to get the tablet and the Raspberry Pi to talk. Here are a few that I have though of so far. Use Wifi (which I really do not want to, Ethernet would be okay) to ssh into the Raspberry Pi (with an external library) and run scripts that way from the Android app. Use a com port for Android (maybe Andropod if there hardware becomes available?) and run scripts on the Raspberry Pi. Those are probably two of the "best" ideas that I can think of for now. Can anyone think of any other "better" ideas? Thanks in advance for the help, Dan

• Multiple peers connected.

  - by Ranbeuer

  I'm developing a game that requires up to four iPhones or iPod Touch to connect each other to play in turns. My question is, how can I accomplish this via GameKit. I've read that using client/server sessions is the way of doing it. But I can't find any examples that would illustrate this. Is it really possible to do it, or there can only be two devices connected at a time. I'd really appreciate if you all could help me with a code sample. Thanks.

• How to take a screen shot in iPhone via code

  Hello friends; I am working on an app and am almost done with it, but the only thing pending is that i am not able to take screen shots of my screen on the touch of the UIButton object.

So can you please provide me with the link or code to do the same, that would be really nice of you Thanks & Regards Radix

• How to know the type of an object in a list?

  - by nacho4d

  Hi, I want to know the type of object (or type) I have in my list so I wrote this: void **list; //list of references list = new void * [2]; Foo foo = Foo(); const char *not_table [] = {"tf", "ft", 0 }; list[0] = &foo; list[1] = not_table; if (dynamic_cast<LogicProcessor*>(list[0])) { //ERROR here ;( printf("Foo was found\n"); } if (dynamic_cast<char*> (list[0])) { //ERROR here ;( printf("char was found\n"); } but I get : error: cannot dynamic_cast '* list' (of type 'void*') to type 'class Foo*' (source is not a pointer to class) error: cannot dynamic_cast '* list' (of type 'void*') to type 'char*' (target is not pointer or reference to class) Why is this? what I am doing wrong here? Is dynamic_cast what I should use here? Thanks in advance EDIT: I know above code is much like plain C and surely sucks from the C++ point of view but is just I have the following situation and I was trying something before really implementing it: I have two arrays of length n but both arrays will never have an object at the same index. Hence, or I have array1[i]!=NULL or array2[i]!=NULL. This is obviously a waste of memory so I thought everything would be solved if I could have both kind of objects in a single array of length n. I am looking something like Cocoa's (Objective-C) NSArray where you don't care about the type of the object to be put in. Not knowing the type of the object is not a problem since you can use other method to get the class of a certain later. Is there something like it in c++ (preferably not third party C++ libraries) ? Thanks in advance ;)

• select distinct over specific columns

  - by Midhat

  A query in a system I maintain returns QID AID DATA 1 2 x 1 2 y 5 6 t As per a new requirement, I do not want the (QID, AID)=(1,2) pair to be repeated. We also dont care what value is selected from "data" column. either x or y will do. What I have done is to enclose the original query like this SELECT * FROM (<original query text>) Results group by QID,AID Is there a better way to go about this? The original query uses multiple joins and unions and what not, So I would prefer not to touch it unless its absolutely necesary

• How to trigger an event ONLY if both dropdowns are selected?

  - by DaveDev

  I have a dropdown select list on my page of class="TypeFilter". I have a jQuery event that fires when a value in that list is selected. $(".TypeFilter").change(function() { // Extract value from TypeFilter and update page accordingly )); I now have to add another list to the page, and I want to implement functionality which will prevent the .change(function() from running unless both are selected. In both lists the first option in the list is some text instructing the user to select one of the items, so I was thinking of just writing some logic to test that both lists have a selected index greater than 0. I think this is a touch unclean though, especially considering that other pages that have a TypeFilter use the same logic. Is there any nifty functionality in jQuery that can do this?

• How can I create a single HTTP Get request for iPhone?

  - by Mph2

  Hi guys! First of all, sorry for my posibly bad english... I got a surely big stupid question... In my enterprise have an automatic door system, that is opened with a HTTP GET request to a file. Example: http://ipaddress/rc.cgi?o=1,50 Where the o=number indicates the amount of seconds that the automatic door will run. The is no need for authentification or nothing (that is made by LAN Radius). So, the question is... How can I make a single button (for example in the springboard) that when you touch it, runs the GET request? You thing that it should be possible with NSURLConection ? Thanks for all

• swipe to delete uitableview cell; a bit jumpy?

  - by Veeru

  I have implemented "swipe to delete" on my table cell. It works fine, how ever, the delete button is a little jumpy; as in, i really have to position my finger on top of the button and carefully touch it to delete the record. I am not sure if am making it clear; let me do my best to explain When the delete button appears; the user has trouble clicking on it, it disappears the moment its clicked. THe user has to try a few times to actually delete the cell. Am not sure what the reason is, it just seems like the delete button gets hidden as though the user has clicked on a different part of the cell. Any suggestsions?

• Are Domain Specific Languages (DSL) bad for the Common Programmer?

  - by iestyn

  I have lately been delving into F# and the new DSL stuff as in the Microsoft SQL Server Modelling CTP, and have some concerns. Will this new idea that will come about be bad for skilled programmers? Is code going to be dumbed down? I know I sound like a luddite, but this does worry me, after spending years of time practising in my craft, and now might be scuttled by genius from within. I am afraid, very afraid. Will I be now trapped in a job that only programs against a DSL and therefore every job that I work on, I have to learn a whole new DSL based on top of a Framework (.net Java), that I will only be allowed to touch certain parts of. I don't think the world is ready for DSL, but the sales pitch is deafening!
