  • Cached/offline maps for iPhone?

    - by Konstantin
    I'd like to use use maps in my application, so that there will be as less as possible traffic. Perfect solution would be caching of map slices. I know it's not possible with google maps (license). I took a look on OpenStreetMaps and it seems as good solution. The next: SDK. The only one I've found is from CloudMade. The problem is, I found no related API methods for caching/offline calls. Are there any alternative solutions?

  • PHP: System Timezone Setting error

    - by marknt15
    Hi, I'm trying to use PHP in the terminal under MAMP but I got an error related to the system's timezone settings. How can I fix this error? $/Applications/MAMP/bin/php5/bin/php echo.php PHP Strict Standards: PHP Startup: It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Asia/Manila' for 'PHT/8.0/no DST' instead in Unknown on line 0 Thanks

  • How can I explain to a programmer that CSS positioning has many benefits over table based layouts?

    - by Pat
    I have a friend who wishes to work as a freelance web developer, but insists that tables are the way forwards for layouts. Several points he maintains in favour of tables: 1 This is what was taught at the beginning of 10 years of programming & computer science degrees. 2 Large companies use tables to achieve 'technical' things. 3 It saves time I have coded him some examples of CSS exactly matching table based layouts, and provided many links to articles explaining SEO and accessibility benefits. From the perspective of a client, I have been explaining to him that I wouldn't hire someone using outdated methods as their main strategy for layout. As he is my friend and I wish him every success, I believe it is important for him to gain the best start when pitching for work. The question again: How can I explain to a programmer that CSS positioning has many benefits over table based layouts?

  • same Linq for two tables

    - by Diana
    I need to do something like this, My two tables have the same signature, but different class so It suppose to work but it is not working. var myTable; if (booleanVariable == true) { myTable = table1; } else { myTable = table2; } var myLinq1 = from p in myTable join r in myOtherTable select p; In this case, I have to initialize myTable I have tried also, var myTable= table2; if (booleanVariable == true) { myTable = table1; } var myLinq1 = from p in myTable join r in myOtherTable select p; then var is type table2, then it can't be changed to table1 type. I need help, I don't want to make a copy paste of all the code. the linq query is huge, and it s nested with 5 or 6 queries. also I have to do this on 12 different methods. Thanks a lot for your help.

  • Building html tables from query data... faster?

    - by Andrew Heath
    With my limited experience/knowledge I am using the following structure to generate HTML tables on the fly from MySQL queries: $c = 0; $t = count($results); $table = '<table>'; while ($c < $t) { $table .= "<tr><td>$results[0]</td><td>$results[1]</td> (etc etc) </tr>"; ++$c; } $table .= '</table>'; this works, obviously. But for tables with 300+ rows there is a noticeable delay in pageload while the script builds the table. Currently the maximum results list is only about 1,100 rows, and the wait isn't long, but there's clearly a wait. Are there other methods for outputting an HTML table that are faster than my WHILE loop? (PHP only please...)

  • Rails 3 routing - what's best practice?

    - by Mattias
    Hi guys, I'm trying out Rails, and I've stumbled across an issue with my routing. I have a controller named "Account" (singular), which should handle various settings for the currently logged in user. class AccountController < ApplicationController def index end def settings end def email_settings end end How would I set-up the routes for this in a proper manner? At the moment I have: match 'account(/:action)', :to => 'account', :as => 'account' This however does not automagically produce methods like account_settings_path but only account_path Is there any better practice of doing this? Remember the Account controller doesn't represent a controller for an ActiveModel. If this is in fact the best practice, how would I generate links in my views for the actions? url_to :controller => :account, :action => :email_settings ? Thanks!

  • How to prevent the copying of text from a textarea?

    - by think123
    I have an online typing software, which I'm currently working on. In the typing software, all is running good but I have come across the problem of dishonest users who might possibly type the text into the textarea, copy it, then reload the page (therefore resetting the timer) and pasting it in straightaway. So I was thinking along the lines of using something like evt.preventDefault(); when javascript detects the pressing of the ctrl / cmd button. But then again I realized that the user could go to the menu bar to press copy. So is there a cross-browser method to do both methods of disabling? Thanks, Lucas EDIT: Please forgive me if I wasn't clear. Please comment on where I wasn't, and I will strive to improve the quality of my questions.

    - by Karthik
    Hi, I have an EXE and DLL running in different process. From DLL I have to send large of amount of data to EXE, which would vary from 50 chars to 2000 chars and more(The data is recordid of records saved in DB). I thought about two options to do that: 1. Using SendMessage- In which data's will be sent in batch. 2. Use an Intermediate file to transfer data. Can anyone list out the pros and cons of methods. I have developed my components using C#.NET Thanks you folks.

  • PHP upload with progress bar

    - by Mitchan Adams
    Hi all I want to create an upload form to upload large files. Thats pretty much easy, however, the upload process itself taks long and basically looks like nothing is happening for a few minutes. So now I'd like to insert a progress bar to show the user that something is happening and they should just sit tight. I've read of numerous methods like APC and certian flash plugins, but my site is hosted on a shared server and I cant install any new applications on it. I'm thinking, maybe if it is possible to read the size of the temp file it creates via an ajax page. By polling the size every few seconds I should be able to get the progress of the upload. Now the question I pose is...where is the temp file situated?

  • Objective-C global array of ints not working as expected

    - by Fran
    In my MyConstants.h file... I have: int abc[3]; In my matching MyConstants.m file... I have: extern int abc[3] = {11, 22, 33}; In each of my other *.m files... I have #import "MyConstants.h" Inside 1 of my viewDidLoad{} methods, I have: extern int abc[]; NSLog(@"abc = (%d) (%d)", abc[1], sizeof(abc)/sizeof(int)); Why does it display "abc = (0) (3)" instead of "abc = (22) (3)"? How do I make this work as expected?

  • LINQ-to-SQL class doesn't implement INotifyPropertyChanging & INotifyPropertyChanged if pulling from

    - by Traples
    I modified my data source in my LINQ-to-SQL class (by the old delete and drag back in method), and was surprised to see the INotifyPropertyChanging & INotifyPropertyChanged interfaces no longer implemented in the generated classes (MyDb.designer.cs). The methods for the individual fields went from looking like this... [Column(Storage="_Size", DbType="NVarChar(100)")] public string Size { get { return this._Size; } set { if ((this._Size != value)) { this.OnSizeChanging(value); this.SendPropertyChanging(); this._Size = value; this.SendPropertyChanged("Size"); this.OnSizeChanged(); } } } To looking like this... [Column(Storage="_Size", DbType="NVarChar(100)")] public string Size { get { return this._Size; } set { if ((this._Size != value)) { this._Size = value; } } } Any ideas on why this happens and how it will affect my application?

  • C# - Moving a control to the mouse's position

    - by APShredder
    Hello everybody. I am trying to get a control to follow the cursor when the user clicks and drag the control. The problem is that 1.) the control doesn't go to the mouse's position, and 2.) the control flickers and flies all over the place. I've tried a few different methods of doing this, but all so far have failed. I've tried: protected override void OnMouseDown(MouseEventArgs e) { while (e.Button == System.Windows.Forms.MouseButtons.Left) { this.Location = e.Location; } } and protected override void OnMouseMove(MouseEventArgs e) { while (e.Button == System.Windows.Forms.MouseButtons.Left) { this.Location = e.Location; } } but neither of these work. Any help is appreciated, and thanks in advance!

  • Standalone jQuery "touch" method?

    - by dclowd9901
    So, I'm looking to implement the ability for a plugin I wrote to read a touch "swipe" from a touch-capable internet device, like an iPhone, iPad or android. Is there anything out there? I'm not looking for something as full as jQtouch, though was considering reverse engineering the code I would need out of it. Any suggestions on the best way to approach this? A snippet of code already available? Addendum: I realize in hindsight the solution won't strictly be jQuery, as I'm pretty sure there aren't any built-in methods to handle this. I would expect standard Javascript to find itself in the answer.

  • How to create a communication layer in android

    - by Palo
    I want to create a communication layer in android. The layer will communicate with server asynchronously. Multiple activities should be able to call methods of the communication layer. The layer will get messages from the server (it is not important for the scope of this question how) and should be able to tell activities to do some work based on these messages. How should I implement this? Should I do this using android Service? The main questions that I need to answer are: How can activities access the layer? How can the layer access activities? How can i make the communication layer live for the lifetime of the application?

  • P/Invoke or C++/CLI for wrapping a C library

    - by Ian G
    Have a moderate size (40-odd function) C API that needs to be called from a C# project. The functions logically break up to form a few classes that will be API presented to the rest of the project. Are there any objective reasons to prefer P/Invoke or C++/CLI for the interoperability underneath that API, in terms of robustness, maintainability, deployment, ...? The issues I could think of that might be, but aren't problematic are: C++/CLI will require an separate assembly, the P/Invoke classes can be in the main assembly. (We've already got multiple assemblies and there'll be the C dlls anyway so not a major issue). Performance doesn't seem differ noticeable between the two methods. Issues that I'm not sure about are: My feeling is C++/CLI will be easier to debug if there's inter-op problem, is this true? Language familiarity enough people know C# and C++ but knowledge of details of C++/CLI are rarer here. Anything else?

  • C++ Asymptotic Profiling

    - by Travis
    I have a performance issue where I suspect one standard C library function is taking too long and causing my entire system (suite of processes) to basically "hiccup". Sure enough if I comment out the library function call, the hiccup goes away. This prompted me to investigate what standard methods there are to prove this type of thing? What would be the best practice for testing a function to see if it causes an entire system to hang for a sec (causing other processes to be momentarily starved)? I would at least like to definitively correlate the function being called and the visible freeze. Thanks

  • What are the pros/cons to these 2 ways of defining parameters for a web service method

    - by Antony Scott
    I have an existing web service I need to expand, but it has not gone into production yet. So, I am free to change the contracts as I see fit. But I am not sure of the best way to define the methods. I am leaning towards Method 2 for no other reason than I cannot think of good names to give the parameters classes! Are there any major disadvantages to using Method 2 over Method 1? Method 1 [DataContract(Namespace = Constants.ServiceNamespace)] public class MyParameters { [DataMember(Order = 1, IsRequired = true)] public int CompanyID { get; set; } [DataMember(Order = 2, IsRequired = true)] public string Filter { get; set; } } [ServiceContract(Namespace = Constants.ServiceNamespace)] public interface IMyService { [OperationContract, FaultContract(MyServiceFault)] MyResult MyMethod(MyParameters params); } Method 2 public interface IMyService { [OperationContract, FaultContract(MyServiceFault)] MyResult MyMethod(int companyID, string filter); }

  • What effect does static const have on a namespace member

    - by user144182
    namespace MyNamespace { static const double GasConstant = 1.987; Class MyClass { // constructors, methods, etc. }; }; I previously had GasConstant declared within the MyClass declaration (and had a separate definition in the source file since C++ does not support const initialization of non-integral types). I however need to access it from other files and also logically it seems like it should reside at the namespace level. My questions is, what effect does static const have in this case? Clearly const means I can't assign a new value to GasConstant, but what does a static member at the namespace mean. Is this similar to filescope static effect, where the member is not accessible outside of the unit?

  • Java compilers or JVM languages that support goto?

    - by unknown
    Is there a java compiler flag that allows me to use goto as a valid construct? If not, are there any third-party java compilers that supports goto? If not, are there any other languages that support goto while at the same time can easily call methods written in Java? The reason is I'm making a language that is implemented in Java. Gotos are an important part of my language; I want to be able to compile it to native or JVM bytecode, although it has to be able to easily use Java libraries (ie. C supports goto, but to use it I'd have to rewrite the libraries in C). I want to generate C or Java, etc source files, and not bytecode or machine code. I'm using a third-party compiler to do that.

  • Can someone please explain to me the basic function of Intents in the Android OS?

    - by K-RAN
    I'm new to programming applications for the Android OS. As far as general architecture of the OS goes, I understand that processes are implemented as Linux processes and that each one is sandboxed. However, I'm utterly confused on the IPCs and syscalls (if any) used. I know that the IBinder is a form of this; parcels are sent back and forth between processes and Bundles are array forms of parcels (?). But even that is still unfamiliar to me. Same with Intents. All in all, I don't understand what kinds of IPCs are implemented and how. Could someone briefly explain to me the specific methods used by user level applications in Android OS to communicate with each other and the OS? I've done kernel programming and played with various IPCs in Linux (Ubuntu and Debian) so it would help immensely if this was all explained in relation to what I'm familiar with... Thanks in advance!
