  • The "correct" way of using multilingual support

    - by Felipe Athayde
    I just began working with ASP.NET and I'm trying to bring with me some coding standards I find healthy. Among such standards there is the multilingual support and the use of resources for easily handling future changes. Back when I used to code desktop applications, every text had to be translated, so it was a common practice to have the language files for every languages I would want to offer to the customers. In those files I would map every single text, from button labels to error messages. In ASP.NET, with the help of Visual Studio, I have the resort of using the IDE to generate such Resource Files (from Tools - Generate Local Resource), but then I would have to fill my webpages with labels - at least that is what I've learned from articles and tutorials. However, such approach looks a bit odd and I'm tempted to guess it doesn't smell that good as well. Now to the question: 1) Should I keep every single text in my website as labels and manage its contents in the resource files? It looks/feels odd specially when considering a text with several paragraphs. 2) Whenever I add/remove something, e.g.: a button, to an aspx file I would have to add it to the resource file as well, because generating the resource file again would simply override all my previous changes to it. That doesn't feel like a reusable code at all for me. Any comment suggestion on this one? Perhaps I got it all wrong from tutorials as it doesn't seem like a standardized matter - specially if it required recompiling the entire application whenever some change has to be done.

  • SQL Compact performance on device

    - by Ben M
    My SQL Compact database is very simple, with just three tables and a single index on one of the tables (the table with 200k rows; the other two have less than a hundred each). The first time the .sdf file is used by my Compact Framework application on the target Windows Mobile device, the system hangs for well over a minute while "something" is done to the database: when deployed, the DB is 17 megabytes, and after this first usage, it balloons to 24 megs. All subsequent usage is pretty fast, so I'm assuming there's some sort of initialization / index building going on during this first usage. I'd rather not subject the user to this delay, so I'm wondering what this initialization process is and whether it can be performed before deployment. For now, I've copied the "initialized" database back to my desktop for use in the setup project, but I'd really like to have a better answer / solution. I've tried "full compact / repair" in the VS Database Properties dialog, but this made no difference. Any ideas? For the record, I should add that the database is only read from by the device application -- no modifications are made by that code.

  • CodeIgniter - Image Validation & Thumbnailing

    - by Sebhael
    I'm currently trying to create a function that validates and creates thumbnails for images on upload - but I'm quite lost on what I'm doing. I'm assuming I'm off on my terminology so I'm not really getting any search results to help point me in the right direction. My playground is a form with 6 upload fields that are required. One of these fields is for a simple 32x32 icon image, another a portrait orientation (most likely) photo, and then 4 standard desktop screenshots -- and I'm using CodeIgniter as my framework. I would like to create a function that validates/thumbnails images, and only have to call it on the validation if at all possible. I know I can achieve this per-image, since the documentation for CI is quite through on this - but to reduce redundancy I'm looking for the better option. Outside of that, I don't even actually understand in full how to manipulate images unless it's just $this-input-post('field') - then calling all functions onto this? I don't know, I'm confused and posting on the actual CI forums has yielded me nothing - so all I'm really looking for is a point in the right direction to understanding what I'm trying to achieve here. This also all might not make any sense, I know it doesn't to me - but I can explain more if needed. Thanks in advance.

  • How to send KeyEvents through an input method service to a Dialog, or a Spinner menu?

    - by shutdown11
    I'm trying to implement an input method service that receives intents sent by a remote client, and in response to those sends an appropriate KeyEvent. I'm using in the input method service this method private void keyDownUp(int keyEventCode) { getCurrentInputConnection().sendKeyEvent( new KeyEvent(KeyEvent.ACTION_DOWN, keyEventCode)); getCurrentInputConnection().sendKeyEvent( new KeyEvent(KeyEvent.ACTION_UP, keyEventCode)); } to send KeyEvents as in the Simple Sofykeyboard Sample, and it works in the home, in Activities... but it doesn't works when a Dialog or the menu of a Spinner is in foreground. The events is sent to the parent activity behind the Dialog. Is there any way to send keys and control the device like using the hardware keys from an input method? Better explanation on what I'm trying to do: I am kind of writng an Input Method that allows to control the device from remote. I write in a client (a java application on my desktop pc) a command (for example "UP"), a server on the device with sendBroadcast() sends the intent with the information, and a receiver in the input method gets it and call keyDownUp with the keycode of the DPAD_UP key. It generally works, but when I go to an app that shows a dialog, the keyDownUp method don't sends the key event to the dialog, for example for select the yes or not buttons, but it keeps to control the activty behind the Dialog.

  • Why Is Apache Giving 403?

    - by ThinkCL
    I am getting 403 Errors from Apache when I send too many, 12, synchronous HTTP Posts via a desktop app I am building in XCode / Objective-C. The 12 POST requests are just a few kb each and go out instantly one after the other and the Apache Error Log shows... client denied by server configuration: /the-path/the-file.php Apache 2.0 PHP 5 and I have this same setup working fine on my local machine. The error is coming from a VPS with my host, which runs very fast and smooth and has plenty of resources. To debug I threw a sleep(1); function (stalls script execution by 1 second) into the php file and that fixed it. This makes me think that I am breaking some limit for too many requests for a single IP in a certain amount of time. I have googled and combed PHP ini and Apache configs, but I cannot find what that directive/setting might be. I should mention that the although it varies the first 4 or 5 POSTS usually work then it starts returning the 403 error intermittently after that. Just really acting like its bogging down. Any ideas?

  • Looking for resources to explain a security risk.

    - by Dave
    I've a developer which has given users the ability to download a zip archive which contains an html document which references a relative javascript file and flash document. The flash document accepts as one of it's parameters a url which is embedded in the html document. I believe that this archive is meant to be used as a means to transfer an advertisement to someone who would use the source to display the ad on their site, however the end user appears to want to view it locally. When one opens the html document the flash document is presented and when the user clicks on the flash document it redirects to this embedded url. However, if one extracts the archive on the desktop and opens the html document in a browser and clicks the flash object, nothing observable happens, they will not be redirected to the external url. I believe this is a security risk because one is transferring from the local computer zone to an external zone. I'm trying to determine the best way to explain this security risk in the simplest of terms to a very end user. They simply believe it's "broken" when it's not broken, they're being protected from a known vulnerability. The developer attempted to explain how to copy the files to a local iis instance, which I highly doubt is running on the users machine, and I do not consider this to be a viable explanation.

  • can I put my sqlite connection and cursor in a function?

    - by steini
    I was thinking I'd try to make my sqlite db connection a function instead of copy/pasting the ~6 lines needed to connect and execute a query all over the place. I'd like to make it versatile so I can use the same function for create/select/insert/etc... Below is what I have tried. The 'INSERT' and 'CREATE TABLE' queries are working, but if I do a 'SELECT' query, how can I work with the values it fetches outside of the function? Usually I'd like to print the values it fetches and also do other things with them. When I do it like below I get an error Traceback (most recent call last): File "C:\Users\steini\Desktop\py\database\test3.py", line 15, in <module> for row in connection('testdb45.db', "select * from users"): ProgrammingError: Cannot operate on a closed database. So I guess the connection needs to be open so I can get the values from the cursor, but I need to close it so the file isn't always locked. Here's my testing code: import sqlite3 def connection (db, arg): conn = sqlite3.connect(db) conn.execute('pragma foreign_keys = on') cur = conn.cursor() cur.execute(arg) conn.commit() conn.close() return cur connection('testdb.db', "create table users ('user', 'email')") connection('testdb.db', "insert into users ('user', 'email') values ('joey', 'foo@bar')") for row in connection('testdb45.db', "select * from users"): print row How can I make this work?

  • Cross-platform HTML application options

    - by Charles
    I'd like to develop a stand-alone desktop application targeting Windows (XP through 7) and Mac (Tiger through Snow Leopard), and if possible iPhone and Android. In order to make it all work with as much common code as possible (and because it's the only thing I'm good at), I'd like to handle the main logic with HTML and JS. Using Adobe AIR is a possibility. And I think I can do this with various application wrappers, using .NET for Windows XP, Objective C for iPhone, Java for Android and native "widget" platform support for Mac and Windows Vista & 7 (though I'd like to keep the widget in the foreground, so the Mac dashboard isn't ideal). Does anyone have any suggestions on where to start? The two sticking points are: I'll certainly need some form of persistent storage (cookies perhaps) to keep state between sessions I'll also probably need access to remote data files, so if I use AJAX and the hosting HTML file resides on the device, it will need to be able to do cross-domain requests. I've done this on the iPhone without any problems, but I'd be surprised if this were possible on other platforms. For me, Android and iPhone will be the easiest to handle, and it looks like I can use Adobe AIR to handle the rest. But I wanted to know if there are any other alternatives. Does anyone have any suggesions?

  • C++ Operator Ambiguity

    - by Scott
    Forgive me, for I am fairly new to C++, but I am having some trouble regarding operator ambiguity. I think it is compiler-specific, for the code compiled on my desktop. However, it fails to compile on my laptop. I think I know what's going wrong, but I don't see an elegant way around it. Please let me know if I am making an obvious mistake. Anyhow, here's what I'm trying to do: I have made my own vector class called Vector4 which looks something like this: class Vector4 { private: GLfloat vector[4]; ... } Then I have these operators, which are causing the problem: operator GLfloat* () { return vector; } operator const GLfloat* () const { return vector; } GLfloat& operator [] (const size_t i) { return vector[i]; } const GLfloat& operator [] (const size_t i) const { return vector[i]; } I have the conversion operator so that I can pass an instance of my Vector4 class to glVertex3fv, and I have subscripting for obvious reasons. However, calls that involve subscripting the Vector4 become ambiguous to the compiler: enum {x, y, z, w} Vector4 v(1.0, 2.0, 3.0, 4.0); glTranslatef(v[x], v[y], v[z]); Here are the candidates: candidate 1: const GLfloat& Vector4:: operator[](size_t) const candidate 2: operator[](const GLfloat*, int) <built-in> Why would it try to convert my Vector4 to a GLfloat* first when the subscript operator is already defined on Vector4? Is there a simple way around this that doesn't involve typecasting? Am I just making a silly mistake? Thanks for any help in advance.

  • import text file containing line breaks into excel

    - by Maximilian Tyrtania
    I have a plain text file looking like this: "some text containing line breaks" I'm trying to talk excel 2004 (Mac, v.11.5) into opening this file correctly. I'd expect to see only one cell (A1) containing all of the above (without the quotes)... But alas, I can't make it happen, because Excel seems to insist on using the CR's as row delimiters, even if I set the text qualifier to double quote. I was sort of hoping that Excel would understand that those line breaks are part of the value - they are embedded in double quotes which should qualify them as part of the value. So my Excel sheet has 5 rows, which is not what I want. I also tried this Applescript to no avail: tell application "Microsoft Excel" activate open text file filename ¬ "Users:maximiliantyrtania:Desktop:linebreaks" data type delimited ¬ text qualifier text qualifier double quote ¬ field info {{1, text format}} ¬ origin Macintosh with tab end tell If I could tell Excel to use a row delimiter other than CR (or LF), well, I'd be a happy camper, but excel seems to allow the change of the field delimiter only, not the row delimiter. Any pointers? Thanks, Max Excel's open

  • Where can I find a powerful, standards compliant, web-based interactive org chart API?

    - by Adam Soltys
    Hi, I'm looking to build an interactive web-based org chart for a large organization. I somewhat like the interface at ancestry.com where you can hover over people and pan/zoom around and click on different nodes to make them the root. Ideally, I'd like it if people could belong to multiple organizational entities like committees, working groups, etc. In other words the API should support graphs in general, not just trees. I'd like to be able to visually explode each organizational substructure into substituents by clicking on it, with a nice animation of the employees ballooning or spilling out so you can really interactively drill down through the organization. I found http://code.google.com/apis/visualization/documentation/gallery/orgchart.html but it looks a bit rudimentary. I know there are desktop tools like OrgPlus and Visio that can build static charts but I'm really looking for a free, web-based API with open standards-based output like SVG or HTML5 Canvas elements rather than Flash or some proprietary output. Something I can embed into a custom web application and style myself. Something interactive.

  • Google Drive API invalid_grant after removing access

    - by Sparafusile
    I have been writing a desktop application that uses the Google Drive API v2. I have the following code: var credential = GoogleWebAuthorizationBroker.AuthorizeAsync ( new ClientSecrets { ClientId = ClientID, ClientSecret = ClientSecret }, new[] { DriveService.Scope.Drive }, "user", CancellationToken.None ) .Result; this.Service = new DriveService( new BaseClientService.Initializer() { HttpClientInitializer = credential, ApplicationName = "My Test App", } ); var request = this.Service.Files.List(); request.Q = "title = 'foo' and trashed = false"; var result = request.Execute(); The first time I ran this code it opened a browser and asked me to grant permissions to the App, which I did. Everything worked successfully until I realized I was using the wrong Google account. At that point I logged into the wrong Google account and revoked access to my App. Now, whenever I run the same code it throws an exception: Error:"invalid_grant", Description:"", Uri:"" When I examine the service and request objects, it looks like the oauth_token isn't getting created any more. I know what I did to mess things up, but I can't figure out how to correct it so I can use a different Google account for testing. What do I need to do?

  • Creating a clickable progress bar

    - by Cory
    What I'm essentially building is a webkit based controller that communicates with a program called Ecoute.app. The controller has a progressbar that indicates the progress made through the currently playing song, but I want to make this bar's position adjustable with a click. function barClick() { var progress = Ecoute.playerPosition(); var width = 142.5; var percentElapsed = progress / length; var position = width * percentElapsed; Ecoute.setPlayerPosition(position); } Is what I have, with Ecoute.playerPosition() returning the player's current position. Width has previously been defined as a dynamic value at var width = 142.5 / length * progress + 1.63; With length being the current track length and progress being the player's position. This has been able to dynamically stretch a progression overlay image to indicate the position of the track via the desktop controller. However, the max width used in the second function does not appear to allow the first function to work properly. Any help possibly determining the correct value or approach would be hugely appreciated.

Should I download portable Firefox 3.0 and test in it too even if I'm not using any new css property/selector which only has support in Firefox 3.5 or testing in 3.5.7 would be enough? And for IE testing in IE 7 would be enough or should i check my site in IE8 (downloading VPC image of IE8 and testing in VM) even if I'm not using any new css property/selector which only has support in IE8? Or is it necessary to use <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" /> in <head> ? But what will happen when user will switch compatibility mode to IE 8 default rendering mode? Can we make site compatible in IE 7 and 8 both without using <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />? If yes, then what special we need to do.care/consider in css to make site identical in both?

  • What is the proper syntax for getting a Makefile to print the output directory of one of its output zip files?

  • Is app stability unusually hard with Java?

    - by wrp
    Java's extensive libraries and tool support are appealing, but I've never tried developing with it because most Java applications I've used have been extremely buggy. This has me puzzled, because I hear that Java is the dominant platform for enterprise development. Maybe it's fine for server-side stuff but not desktop applications. I'm not talking about things like the long compile/startup times or the random latencies due to garbage collection. This is about things just going wrong. Some of the most common problems I see are: corrupted icons corrupted fonts, in menus usually and editing areas sometimes inaccurate framing of GUI elements dialogs sometimes popping up blank Maybe the problems are mostly with Swing. I've rarely used a Java application long enough to find deeper issues. I can think of a few possible explanations for what I've experienced: It's possible to write stable apps with Java, just harder. Java apps are always buggy and enterprise users just put up with it. Server-side apps are fine because just Swing is buggy. I'm living under a curse and need the services of a good witchdoctor.

  • C++, Ifstream opens local file but not file on HTTP Server

    Hi, I am using ifstream to open a file and then read from it. My program works fine when i give location of the local file on my system. for eg /root/Desktop/abc.xxx works fine But once the location is on the http server the file fails to open. for eg http://192.168.0.10/abc.xxx fails to open. Is there any alternate for ifstream when using a URL address? thanks. part of the code where having problem: bool readTillEof = (endIndex == -1) ? true : false; // Open the file in binary mode and seek to the end to determine file size ifstream file ( fileName.c_str ( ), ios::in|ios::ate|ios::binary ); if ( file.is_open ( ) ) { long size = (long) file.tellg ( ); long numBytesRead; if ( readTillEof ) { numBytesRead = size - startIndex; } else { numBytesRead = endIndex - startIndex + 1; } // Allocate a new buffer ptr to read in the file data BufferSptr buf (new Buffer ( numBytesRead ) ); mpStreamingClientEngine->SetResponseBuffer ( nextRequest, buf ); // Seek to the start index of the byte range // and read the data file.seekg ( startIndex, ios::beg ); file.read ( (char *)buf->GetData(), numBytesRead ); // Pass on the data to the SCE // and signal completion of request mpStreamingClientEngine->HandleDataReceived( nextRequest, numBytesRead); mpStreamingClientEngine->MarkRequestCompleted( nextRequest ); // Close the file file.close ( ); } else { // Report error to the Streaming Client Engine // as unable to open file AHS_ERROR ( ConnectionManager, " Error while opening file \"%s\"\n", fileName.c_str ( ) ); mpStreamingClientEngine->HandleRequestFailed( nextRequest, CONNECTION_FAILED ); } }

  • Getting Junk characters while trying to print the file contents using Java

    - by user1523797
    I am reading a file's contents and trying to print the contents using java. But it prints junk characters along with the file content. Code: import java.io.*; public class ReadFile { public String readFile(String filePath){ StringBuilder contents = new StringBuilder(); File file = new File(filePath); try{ String lines = null; FileReader fileReader1 = new FileReader(file); BufferedReader buffer = new BufferedReader(fileReader1); while((lines = buffer.readLine())!=null){ contents.append(lines); } buffer.close(); } catch(FileNotFoundException ex){ System.out.println("File not found."); }catch(IOException ex){ System.out.println("Exception ocurred."); } return contents.toString(); } public static void main(String[] args){ ReadFile rf = new ReadFile(); String lines = rf.readFile("C:\\Data\\FaultDn.txt"); System.out.println("Original file contents: " + lines); } } The file contents are: partner.cisco.com:org-root/mac-pool-QA_MAC_Pool_5-Sep-2012_12:00 The output is: ![Alt Output](C:\Users\safarhee\Desktop\Output.jpg) Can you please point me to what I am missing in this code?

  • C# Sql Connection Best Practises 2013

    - by Pete Petersen
    With the new year approaching I'm drawing up a development plan for 2013. I won't bore you with the details but I started thinking about whether the way I do things is actually the 'correct' way. In particular how I'm interfacing with SQL. I create predominantly create WPF desktop applications and often some Silverlight Web Applications. All of my programs are very Data-Centric. When connecting to SQL from WPF I tend to use Stored Procedures stored on the server and fetch them using ADO.NET (e.g. SQLConnection(), .ExecuteQuery()). However with Silverlight I have a WCF service and use LINQ to SQL (and I'm using LINQ much more in WPF). My question is really is am I doing anything wrong in a sense that it's a little old fashioned? I've tried to look this up online but could find anything useful after about 2010 and of those half were 'LINQ is dead!' and the other 'Always use LINQ' Just want to make sure going forward I'm doing the right things the right way, or at least the advised way :). What principles are you using when connecting to SQL? Is it the same for WPF and Silverlight/WCF?

  • iMX31 dependencies?

    - by Abhi
    Dear all I am beginner in an silverlight application. So at first i looked on demo application which is provided by wince 6.0 r3 at location WINCE600\PUBLIC\COMMON\OAK\DEMOS\XAMLPERF - this contains c++ code and WINCE600\PUBLIC\COMMON\OAK\FILES\XAMLPERF - this contains xaml file with the images Now before running this application in an emulator. I at first proceeded with the following: I have first taken my workspace went to catalog item and added "Silverlight for Windows Embedded" from the drop down menu of an catalog item Then right clicked on solution explorer and choosed on properties and under configuration in drop down menu i have selected environment variables where i have added new variable called "sysgen_samplexamlperf" and assigned value as 1 for that variable. Now after rebuiding the application, i have dumped the image into emulator and i found that at desktop of device emulator i can see the exe file to which i run and i can see the application is working fine with 3d effects. Now same thing i proceeded in iMX31 hardware and i was not able to see the application running in a proper manner as it was performing in an emulator. So now what i feel is that there be any dependency when we run the application on hardware. So what can be the dependency? Also in this location "WINCE600\PUBLIC\COMMON\OAK\FILES\XAMLPERF" the images are in png format. So is there any dependency with an image format? Thanks and regards
