• cc1plus: error: include: Value too large for defined data type when compiling with g++

  - by Android

  I am making a project that should compile on Windows and Linux. I have made the project in Visual Studio and then made a makefile for linux. I created all the files in Windows with VS. It compiles and runs perfectly in VS but when I run the makefile and it runs g++ I get $ g++ -c -I include -o obj/Linux_x86/Server.obj src/Server.cpp cc1plus: error: include: Value too large for defined data type cc1plus: error: src/Server.cpp: Value too large for defined data type The code is nothing more than a Hello World atm. I just wanted to make sure that everything was working before I started development. I have tried searching but to no avail. Any help would be appreciated.

• ASP.NET/AJAX - Timer delay

  - by Julian

  I've got a problem with the timer in asp.net ajax. The timer needs to trigger every second so I put the delay of the timer (don't know the real name atm) at 1000. Now when I put this timer inside an UpdatePanel it doesn't really trigger every second because the timer also gets updated in the UpdatePanel. But when I put the timer outside the update panel it keeps kinda refreshing the page, so whenever I put a button on the same page I need to press and release this button within 1 second else it gets refreshed. Also I saw that even outside of the UpdatePanel the timer isn't a real second. Any solutions?

• what causes the .NET SerialPort class DataReceived event to fire?

  - by Klay

  I understand from the MSDN docs that the event DataReceived will not necessarily fire once per byte. But does anyone know what exactly is the mechanism that causes the event to fire? Does the receipt of each byte restart a timer that has to reach, say 10 ms between bytes, before the event fires? I ask because I'm trying to write an app that reads XML data coming in from a serial port. Because my laptop has no serial ports, I use a virtual serial port emulator. (I know, I know--I can't do anything about it ATM). When I pass data through the emulated port to my app, the event fires once for each XML record (about 1500 bytes). Perfect. But when a colleague at another office tries it with two computers connected by an actual cable, the DataReceived event fires repeatedly, after every 10 or so bytes of XML, which totally throws off the app.

• 3-legged-oauth and Google ContactsClient problem

  - by PanosJee

  Hi I am using 3-legged-oauth to import a users' Google contacts in my app. I did not find the ContactsClient library but i was using only the ContacsService and i was fetching the ContactsFeed but that resulted to not having a lot of data. After the user allows my apps i store the auth_token key and secret so i can run a cron task to fetch contacts' updates I am using this code atm: google = gdata.contacts.service.ContactsService(source=GOOGLE_OAUTH_SETTINGS['APP_NAME']) google.SetOAuthInputParameters(GOOGLE_OAUTH_SETTINGS['SIG_METHOD'], GOOGLE_OAUTH_SETTINGS['CONSUMER_KEY'], consumer_secret=GOOGLE_OAUTH_SETTINGS['CONSUMER_SECRET']) access_token = gdata.auth.OAuthToken(user_oauth_token, user_oauth_secret) access_token.oauth_input_params = google.GetOAuthInputParameters() google.SetOAuthToken(access_token) feed = google.GetContactsFeed() When i try to use the contacts client contacts_client = gdata.contacts.client.ContactsClient( source=GOOGLE_OAUTH_SETTINGS['APP_NAME']) feed2 = contacts_client.GetContacts(auth_token = access_token) I get the following error (please note that the access_token is the same as above and I user 3-legged-oauth HMAC) Actual results: File "/Library/Python/2.5/site-packages/atom/client.py", line 108, in request auth_token.modify_request(http_request)

• Accessing database problem

  - by anarche

  Ok, so I've got an SQLiteOpenHelper that prepares and returns a SQLiteDatabase object; this is written singleton-pattern, so the database is opened once and only closed when the Activity closes. From there I have three database wrappers encapsulating the queries (some returning cursors to datasets, some inserting data) used by the Activity. I want to insert data from one View, then have that automatically update in another View on the same Dialogue. I'm writing this on a notepad and testing on the phone (since the emulator crashes the notepad...), so I can't pull up stacktraces atm. So questions: 1) are there limitations to writing to a database, when there are cursors open on the database? 2) Does a Cursor.requery()? call update the ListView with the cursor as a data connector?

• Strategies for generating Zend Cache Keys

  - by emeraldjava

  ATM i'm manually generating a cache key based on the method name and parameters, then follow to the normal cache pattern. This is all done in the Controller and i'm calling a model class that 'extends Zend_Db_Table_Abstract'. public function indexAction() { $cache = Zend_Registry::get('cache'); $individualleaguekey = sprintf("getIndividualLeague_%d_%s",$leagueid,$division->code); if(!$leaguetable = $cache->load($individualleaguekey)) { $table = new Model_DbTable_Raceresult(); $leaguetable = $table->getIndividualLeague($leagueid,$division,$races); $cache->save($leaguetable, $individualleaguekey); } $this->view->leaguetable = $leaguetable; .... I want to avoid the duplication of parameters to the cache creation method and also to the model method, so i'm thinking of moving the caching logic away from my controller class and into model class packaged in './model/DbTable', but this seems incorrect since the DB model should only handle SQL operations. Any suggestions on how i can implement a clean patterned solution?

• Drag and drop an image from desktop to a web text editor (implementation in javascript)

  - by fatmatto

  I tried to write reasonably short title but i failed i guess.. Hi everybody here's what i'm trying to do: I want to implement a web text editor able to recognize when the user drag a image file over it's editing surface and it automa(gically) starts the upload and insert the image near the cursor position. In other words i don't want the user to do the usual "insert-image-browse-ok". Atm i am not very good at javascript ... i know JQuery but i have not a clear idea about how to implement this... i don't know if there's an event handler able to help me in this situation... if not then there should be i think or web apps would miss some kind of interactivity. I've heard miracles about HTML5 could it help me? I've seen such things in Google Wave but that surface doesn't seem to be a form field... google lab's black magic i guess.... Thank you in advance.

• Efficient persistent storage for simple id to table of values map for java

  - by wds

  I need to store some data that follows the simple pattern of mapping an "id" to a full table (with multiple rows) of several columns (i.e. some integer values [u, v, w]). The size of one of these tables would be a couple of KB. Basically what I need is to store a persistent cache of some intermediary results. This could quite easily be implemented as simple sql, but there's a couple of problems, namely I need to compress the size of this structure on disk as much as possible. (because of amount of values I'm storing) Also, it's not transactional, I just need to write once and simply read the contents of the entire table, so a relational DB isn't actually a very good fit. I was wondering if anyone had any good suggestions? For some reason I can't seem to come up with something decent atm. Especially something with an API in java would be nice.

• Spring, Hibernate and Ehcache - Wrong entities

  - by asrijaal

  Hi there, I've got a webapp which uses spring+hibernate for my data layer. I'm using 2nd level caching with ehcache as provider. Everything seems to work so far but sometimes we encounter a problem which I can't really figure out atm. One of my tables is used for labels within the application - every user who logs access this table with his set language. Works for 90% of the time. But sometimes the user gets labels for the wrong language, e.g. instead of german everything turns to italian. After a logout and login all labels are correct. Does anyone of you encountered something like this? I'm not sure where to look at: spring+hibernate+ehcache is a solid package or is it not? Cheers

• Servlets, long operations

  - by asrijaal

  Hi there, I'm refactoring a big piece of code atm where a long taking operation is executed in a servlet. Now sometimes I don't get a response after the operation has finished. (It has finished because it is printed into the logs) What I wish to achieve would some "fire and forget" behavior by the servlet. I would pass my params to the action and the servlet would immediately return a status (something like: the operation has started, check your logs for further info) Is this possible with servlet 2.5 spec? I think I could get such a behavior with JMS maybe any other solutions out there?

• Rewriting a simple Pygame 2D drawing function in C++

  - by Dominic Bou-Samra

  I have a 2D list of vectors (say 20x20 / 400 points) and I am drawing these points on a screen like so: for row in grid: for point in row: pygame.draw.circle(window, white, (particle.x, particle.y), 2, 0) pygame.display.flip() #redraw the screen This works perfectly, however it's much slower then I expected. I want to rewrite this in C++ and hopefully learn some stuff (I am doing a unit on C++ atm, so it'll help) on the way. What's the easiest way to approach this? I have looked at Direct X, and have so far followed a bunch of tutorials and have drawn some rudimentary triangles. However I can't find a simple (draw point).

• What is so great about STL?

  - by Zygrob

  Hello StackOverflow. I am a Java developer trying to learn C++. I have many times read over the web (including StackOverflow) that STL is the best collections library that you can get in *any* language. (Sorry, I do not have any citations atm) However after studying some STL, I am really failing to see what makes STL so special. Would you please shed some light on what sets STL apart from the collection libraries of other languages and make it the _best_ collection library? Thanks in advance, Zygr??b.

• Updating table takes very long time

  - by rrejc

  Hi all, I have a table in MsSQL Server 2008 (SP2) containing 30 millios of rows, table size 150GB, there are a couple of int columns and two nvarchar(max) columns: one containing text (from 1-30000 characters) and one containg xml (up to 100000 characters). Table doesn't have any primary keys or indexes (its is a staging table). So atm I am running a query: UPDATE [dbo].[stage_table] SET [column2] = SUBSTRING([column1], 1, CHARINDEX('.', [column1])-1); the query is running for 3 hours (and it is still not completed), which I think is too long. Is It? I can see that there is constant read rate of 5MB/s and write rate of 10MB/s to .mdf file. How can I find out why the query is running so long? The "server" is i7, 24GB of ram, SATA disks on RAID 10. Many thanks!

• release viewcontroller after presenting modally

  - by Jonathan

  I was watching CS193P Stanford course on Itunes, and in one of the lectures a demo was given and There it was said you could present the viewcontroller modally and then release it. Roughly like this (I know this isn't perfect but I'm on my PC atm) [self.view presentcontentmodally:myVC] [myVC release]; However this seems to produce problems. If I put a NSLog(@"%d", [myVC retainCount]) between those two lines then it returns 2 implying it is ok to release. However when I dismiss the myVC the app crashes. Nothing in the NSlog and the debugger won't show where it stopped. But I used malloc-history or something that some blog said would help. And found that it was the myVC. So should I be releasing myVC? (also when the modalVC has been dissmissed should the app's memory usuage go back to before the modalVC was presented?)

• Database permissions and ORMs

  - by Jonn

  I've been using .NET's Entity Framework a lot lately and have absolutely no wish to go back to using Stored Procedures. Been shocked though that the company I'm building this project for had a policy where applications were only given accounts that only had permissions to access stored procedures! Apparently, they believe that there's a security risk involved in allowing applications to access the tables/views directly. I don't get this. My first question is, can someone enlighten me as to what kind of security risk applications having direct access to the database may pose? AND If that's the case, are there any other ORM solutions that can provide a workaround to this (I can't think of any logical possibility atm) that would allow me to circumvent the restrictions on the user account to be assigned to me? OR is my understanding that I'd need direct permissions for the tables and views wrong?

• Web based interface for open SSL client certificates

  - by Felix

  Hi there! We are currently developing a apache2-based web application and want to invite some beta testers to give it a try. To be on the safe side, access should be provided by individual browser certificates (.p12) which are issued using a (fake) CA. Our users should be passing a complete register/login process and some of them will be granted administrative privileges within the application. That's why a preceding simple web-based authentication won't be sufficient. Atm, I using a serverside shellscript to generate the certificates each time. Do you know about a small, web-based tool to simplify the process of generating / revoking those certificates? Maybe an overview of the CA's index.txt plus the option to revoke a cert and a link to download them directly?

• Is sending a PDF as encoded byte array in XML sensible

  - by simonjwoods

  Hi I am looking to return a PDF from a webservice call. (ATM, a custom proxy is required at the client-side) AFAICS, there are 2 ways of doing it a) Return the link to a web-accessible location b) Encode the PDF and include it in the XML In my circumstance, a) will require 2 trips from the client, the first to get the path and the second to get the file. However, wrt b), this link (http://www.coderanch.com/t/279020/Streams/java/wrting-bytearray-xml-file#1283263) suggests that it isn't a good idea to encode a PDF, though without explanation. I'd be grateful if someone would offer recommendations of the above (and potentially, other alternatives). Many thx Simon

• custom Filter Android won't show me the results

  - by TiGer

  Hi, I have been implementing a class which class extends ArrayAdapter and implements Filterable. The filtering part (in the performFiltering method()) seems to go ok, it fills the FilterResults object just as expected. But then I think I'm not doing it right on how to publish the results, atm I have : protected void publishResults(CharSequence prefix, FilterResults results) { // NOTE: this function is *always* called from the UI thread. subItems = (Vector)results.values; notifyDataSetChanged(); } But this simply won't "populate" my List with the received data. So now my question is how do I populate my List with the received results ? Do I have to do that programmatically ?

• How can i test my DB speed? (Learning)

  - by acidzombie24

  I have design a database. Theres no columns with indexing, nor any code for optimizing. I am positive i should index certain columns since i search them a lot. My question is HOW do i test if any part of my database will be slow? ATM I am using sqlite and i will be switching to either MS Sql or MySql based on my host provider. Will creating 100,000 records in each table be enough? Or will that always be fast in sqlite and i need to do 1mil? Do i need 10mil before a database will become slow? Also how do i time it? I am using C# so should i use StopWatch or is there a ADO.NET/Sqlite function i should use?

• AJAX with jQuery not returning data

  - by James P

  This is my Javascript: $(document).ready(function() { $('#like').bind('keydown', function(e) { if(e.keyCode == 13) { var likeMsg = $('#like').val(); if(likeMsg) { // Send the AJAX request to like.php $.ajax({ url: 'like.php', success: function(data) { alert('Content: ' + data); } }); } } }); }); And this is my like.php file: <?php echo "It works! :)"; ?> When I press enter on the #like input, it seems the AJAX request is sent and an alert box comes up saying: Content:, but there's no data being sent back from like.php... I have checked if the file exists and if it's in the same directory and whatever and it is, so I'm pretty much clueless atm. Does anyone know what could be wrong here? Cheers.

• How to redirect with .htaccess (keeping legacy links)

  Hello, I recently switched CMSes. While using Wordpress, I had this permalink convention: "/year/post". Now, I'd like to have "year/month/post". To keep legacy links, I need to redirect from "http://site.com/2009/sample-post" to "http://site.com/2009/01/sample-post". "01" should be permanent in this case. This is what I've got atm: RewriteEngine on RewriteCond $1 !^(images|system|themes|_|wp-content|mint|assets|favicon\.ico|robots\.txt|index\.php) [NC] RewriteRule ^(.*)$ /index.php?/$1 [L] Thanks in advance!

• Generate multiple attribute?

  - by acidzombie24

  ATM i cant quiet imagine how this will work. I'm sure it can be done. I notice a pattern use in my attribute where i always use 3 specific attributes together. Take the below as an example [MyAttr(4, @"a"), MyAttr(41, "b"), MyAttr(45, "ab")] Mine is much more complicated but i would like to define one attribute with more params to generate the data above. How might i do that? Lets say my one attribute will look like this MyAttr2(4, 41, "a", "b"); //4+41=45, "a"+"b" = "ab" How might i generate the 3 MyAttr to apply to a class using MyAttr2?
