• C++ MFC server app with sockets crashes and I cannot find the fault, help!

  - by usermeister

  My program has one dialog and two sockets. Both sockets are derived from CAsyncSocket, one is for listening, other is for receiving data from client. My program crashes when client tries to connect to server application and server needs to initialize receiving socket. This is my MFC dialog class. class CFileTransferServerDlg : public CDialog { ... ListeningSocket ListenSock; ReceivingSocket* RecvSock; void OnAccept(); // called when ListenSock gets connection attempt ... }; This is my derived socket class for receiving data that calls parent dialogs method when event is signaled. class ReceivingSocket : public CAsyncSocket { CFileTransferServerDlg* m_pDlg; // for accessing parent dialogs controls virtual void OnReceive(int nErrorCode); } ReceivingSocket::ReceivingSocket() { } This is dialogs function that handles incoming connection attempt when listening socket gets event notification. This is where the crash happens. void CFileTransferServerDlg::OnAccept() { RecvSock = new ReceivingSocket; /* CRASH */ } OR void CFileTransferServerDlg::OnAccept() { ReceivingSocket* tmpSock = new ReceivingSocket; tmpSock->SetParentDlg(this); CString message; if( ListenSock.Accept(*tmpSock) ) /* CRASH */ { message.LoadStringW(IDS_CLIENT_CONNECTED); m_txtStatus.SetWindowTextW(message); RecvSock = tmpSock; } } My program crashes when I try to create a socket for receiving file sent from client application. OnAccept starts when Listening socket signals incoming connection attempt, but my application then crashes. I've tried running it on another computer and connection attempt was succesful. What could be wrong? Error in debug mode: Unhandled exception at 0x009c30e1 in FileTransferServer.exe: 0xC0000005: Access violation reading location 0xccccce58.

• CodeIgnither OAuth 2.0 database setup for users and access_tokens

  - by xref

  Per this question I am using CodeIgniter and OAuth 2 in an attempt to provide SSO for internal users of my webapp, ideally verifying them against their Google Apps account. No registrations or anything, just existing users. Using the CI oauth2 spark I'm getting back from Google an OAuth token similar to below: OAuth2_Token_Access Object ( [access_token:protected] => dp83.AHSDj899sDHHD908DHFBDjidkd8989dDHhjjd [expires:protected] => 1349816820 [refresh_token:protected] => [uid:protected] => ) And using that token I can retrieve some user info from Google: [uid] => 3849450385394595 [nickname] => this_guy [name] => This Guy [first_name] => This [last_name] => Guy [email] => [email protected] [location] => [image] => [description] => [urls] => Array ( ) Now to allow the 15 people or so who will be using the webapp currently to log in, do I need to create a users table in the mysql database with their email address as a key? Then compare the email which just came back from the Google OAuth request and see if it exists in my users table? What about the Google access_token, do I store that now along with the email which already existed in the users table? Related: How would I go about verifying the user automatically in the future against that access_token so they don't have to go through the whole OAuth approval process with Google again?

• php script randomly hangs up

  - by sergdev

  I install php 5 (more precisely 5.3.1) as apache module. After this one of my application becomes randomly hang up on mysql_connect - sometimes works, sometimes no, sometimes reload of page helps. How can this be fixed? I use Windows Vista, Apache/2.2.14 (Win32) PHP/5.3.1 with php module, MySql 5.0.67-community-nt. After a minute I obtain the error message: Fatal error: Maximum execution time of 60 seconds exceeded in path\to\mysqlcon.php on line 9 I run MySql locally and heavy load could not be a reason: SHOW PROCESSLIST shows about 3 process SHOW VARIABLES LIKE 'MAX_CONNECTIONS' is 100. UPDATE: At first I thought that this is connected with mysql_connect. But now I can't say for certain. More difficult thing is when I insert the line to debug: $fh = fopen("E://_debugLog", 'a'); fwrite($fh, __FILE__ . " : " . __LINE__ . "\n"); fclose($fh); script start working near that location as a rule.

• [Ruby on Rails] complex model relationship

  - by siulamvictor

  I am not sure am I doing these correct. I have 3 models, Account, User, and Event. Account contains a group of Users. Each User have its own username and password for login, but they can access the same Account data under the same Account. Events is create by a User, which other Users in the same Account can also read or edit it. I created the following migrations and models. User migration class CreateUsers < ActiveRecord::Migration def self.up create_table :users do |t| t.integer :account_id t.string :username t.string :password t.timestamps end end def self.down drop_table :users end end Account migration class CreateAccounts < ActiveRecord::Migration def self.up create_table :accounts do |t| t.string :name t.timestamps end end def self.down drop_table :accounts end end Event migration class CreateEvents < ActiveRecord::Migration def self.up create_table :events do |t| t.integer :account_id t.integer :user_id t.string :name t.string :location t.timestamps end end def self.down drop_table :events end end Account model class Account < ActiveRecord::Base has_many :users has_many :events end User model class User < ActiveRecord::Base belongs_to :account end Event model class Event < ActiveRecord::Base belongs_to :account belongs_to :user end so.... Is this setting correct? Every time when a user create a new account, the system will as for the user information, i.e. username and password. How can I add them into correct tables? How can I add a new event? I am sorry for such a long question. I am not very understand the rails way in handling such data structure. Thank you guys for answering me. :)

• Global name not defined error in Django/Python trying to set foreignkey

  - by Mark

  Summary: I define a method createPage within a file called PageTree.py that takes a Source model object and a string. The method tries to generate a Page model object. It tries to set the Page model object's foreignkey to refer to the Source model object which was passed in. This throws a NameError exception! I'm trying to represent a website which is structured like a tree. I define the Django models Page and Source, Page representing a node on the tree and Source representing the contents of the page. (You can probably skip over these, this is a basic tree implementation using doubly linked nodes). class Page(models.Model): name = models.CharField(max_length=50) parent = models.ForeignKey("self", related_name="children", null=True); firstChild = models.ForeignKey("self", related_name="origin", null=True); nextSibling = models.ForeignKey("self", related_name="prevSibling", null=True); previousSibling = models.ForeignKey("self", related_name="nxtSibling", null=True); source = models.ForeignKey("Source"); class Source(models.Model): #A source that is non dynamic will be refered to as a static source #Dynamic sources contain locations that are names of functions #Static sources contain locations that are places on disk name = models.CharField(primary_key=True, max_length=50) isDynamic = models.BooleanField() location = models.CharField(max_length=100); I've coded a python program called PageTree.py which allows me to request nodes from the database and manipulate the structure of the tree. Here is the trouble making method: def createPage(pageSource, pageName): page = Page() page.source = pageSource page.name = pageName page.save() return page I'm running this program in a shell through manage.py in Windows 7 manage.py shell from mysite.PageManager.models import Page, Source from mysite.PageManager.PageTree import * ... create someSource = Source(), populate the fields, and save it ... createPage(someSource, "test") ... NameError: global name 'source' is not defined When I type in the function definition for createPage into the shell by hand, the call works without error. This is driving me bonkers and help is appreciated.

• Installing Plugins from Cloud p2 repository in Eclipse IDE

  - by user1495036

  I have been recently reading a lot about p2 for a requirement of mine. Most of the p2 documentation online points to p2 for RCP. My requirement is for a plugin repo. I have a plugin that is used within Eclipse IDE. I dnt want to change the repo location but based on the Eclipse Version, if the user looks for Install New Software or Check for Updates it needs to download the respective plugins. My repo currently contains all the plugins for all the versions. but i need to everytime give a different URL to my user based on the Version. For e.g i am using Eclipse 3.7(Indigo). I install the plugin thru Install New Software by adding the p2 Repo URL. Now the user decides to for some requirement move to Eclipse 3.6, I want him to connect to the same p2 Repo URL and download the plugins created for Eclipse 3.6. This is definitely possible using p2 Discovery, or i could categorize the downloads using composite repository but i dnt want to do any of these. Just want to kno is there any API that i can hold on to, so that before processing the URL and finding the updates, i can check the version of Eclipse and redirect it based on the version to an internal URL. This is possible in RCP, want to kno if i can do it in Eclipse p2 UI. All the p2 UI looks to be internal classes. Any directives would be appreciated. Malai

• Can you do this with Hudson?

  - by damian

  I want to create a hudson job, that takes an id as a parameter. And use that id to calculate the svn-repo path. Where I work you have a svn path for every issue that you resolve. And then all the issues are joined into a single svn-path. What I want to do is to run static code analysis on the partial issues. So I think maybe having an Ant build.xml that I use for every issue, then, parametrize the job with the issue id. I have tried to achieve that but the svn path doesn't replace the parameter. I have tried with #issueId, %issueId%, ${issueId} and ${env.issueId} without success. Jump error like: Location 'http://svn-path:8181/svn/devSet/issues/${env.chuid}' does not exist Checking out a fresh workspace because C:\Documents and Settings\dnoseda\.hudson\jobs\test\workspace\${env.chuid} doesn't exist Checking out http://svn-path:8181/svn/devSet/issues/${env.chuid} ERROR: Failed to check out http://svn-path:8181/svn/devSet/issues/${env.chuid} org.tmatesoft.svn.core.SVNException: svn: '/svn/!svn/bc/46190/devSet/issues/$%7Benv.chuid%7D' path not found: 404 Not Found (http://svn-path:8181) at org.tmatesoft.svn.core.internal.wc.SVNErrorManager.error(SVNErrorManager.java:64) at org.tmatesoft.svn.core.internal.wc.SVNErrorManager.error(SVNErrorManager.java:51) at I am think that I can not do what I want.

• How do I save the edits for a checkbox that implements an email notification?

  - by Ralph The Mouf

  On my site, a user gets email notifications when someone comments on their profile, or comments on their blog etc...I have made a email settings page that has checkboxes to allow the user to decide to receive emails or not. This is what I am wrapping around the email notification code chunck for the pages that have the php mail: <?php if(isset($_POST['email_toggle']) && $_POST['email_toggle'] == 'true') { if(isset($_POST['commentProfileSubmit']) && $auth) { $query etc $to = etc } } My question is what do I put on the email settings script that has the actual check boxes to make them stay checked or unchecked once you submit your settings? Another words what do I put in the if(isset portion to implement the changes? if(isset($_POST['email_toggle']) && $_POST['email_toggle'] == 'true') { /* what do I put here? */ header("Location: Profile.php?id=" . $auth->id); mysql_query($query,$connection); /* input/check boxes and submit button */ <tr> <td class="email_check"> <input type="checkbox" name="email_toggle" value="true" checked="checked" /> Receive email Notifications When Someone Answers A Question You've Answered </td> </tr> <tr> <td> <input style="margin:10px 0px 0px 10px;" class="submit" type="submit" name="email_toggle" value="Save Settings" /> </td> </tr> }

• Uniquely identify files/folders in NTFS, even after move/rename

  - by Felix Dombek

  I haven't found a backup (synchronization) program which does what I want so I'm thinking about writing my own. What I have now does the following: It goes through the data in the source and for every file which has its archive bit set OR does not exist in the destination, copies it to the destination, overwriting a possibly existing file. When done, it checks for all files in the destination if it exists in the source, and if it doesn't, deletes it. The problem is that if I move or rename a large folder, it first gets copied to the destination even though it is in principle already there, just has a different path. Then the folder which was already there is deleted afterwards. Apart from the unnecessary copying, I frequently run into space problems because my backup drive isn't large enough to hold the original data twice. Is there a way to programmatically identify such moved/renamed files or folders, i.e. by NTFS ID or physical location on media or something else? Are there solutions to this problem? I do not care about the programming language, but hints for doing this with Python, C++, C#, Java or Prolog are appreciated.

• C Programming. How to deep copy a struct?

  - by user69514

  I have the following two structs where "child struct" has a "rusage struct" as an element. Then I create two structs of type "child" let's call them childA and childB How do I copy just the rusage struct from childA to childB? typedef struct{ int numb; char *name; pid_t pid; long userT; long systemT; struct rusage usage; }child; typedef struct{ struct timeval ru_utime; /* user time used */ struct timeval ru_stime; /* system time used */ long ru_maxrss; /* maximum resident set size */ long ru_ixrss; /* integral shared memory size */ long ru_idrss; /* integral unshared data size */ long ru_isrss; /* integral unshared stack size */ long ru_minflt; /* page reclaims */ long ru_majflt; /* page faults */ long ru_nswap; /* swaps */ long ru_inblock; /* block input operations */ long ru_oublock; /* block output operations */ long ru_msgsnd; /* messages sent */ long ru_msgrcv; /* messages received */ long ru_nsignals; /* signals received */ long ru_nvcsw; /* voluntary context switches */ long ru_nivcsw; /* involuntary context switches */ }rusage; I did the following, but I guess it copies the memory location, because if I changed the value of usage in childA, it also changes in childB. memcpy(&childA,&childB, sizeof(rusage)); I know that gives childB all the values from childA. I have already taken care of the others fields in childB, I just need to be able to copy the rusage struct called usage that resides in the "child" struct.

• Combining JavaScript for Google Analytics with yours. (Asynchronous tracking.)

  - by lorenzo 72

  I have a JavaScript file which is loaded up at the end of my HTML page. Rather than adding the script code for asynchronous tracking for Google in yet another script I would rather combine the two scripts together. So instead of this: <html> ... <script src="myScript.js"> <!-- google analytics --> <script type="text/javascript"> var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-XXXXX-X']); _gaq.push(['_trackPageview']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js'; (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(ga); })(); </script> </html> I would have that bit of code in the second script tag at the end of my 'myScript.js'. I have not found one place in google documentation where it suggests to combine the script with yours.

• Changing the href attribute on hover with jQuery

  - by AverageJoe

  Ok, I have an html page that is loaded into another html page via PHP (ok so its a PHP page, whatever). The page that is loaded is a list of hyperlinks. I need to change the href attribute to make the hyperlinks relative to the location of the stored images they refer too. When i load the page containing the hyperlinks the links are relative to the web host server, not the server that the page is actually hosted from. Somthing like this: <div #screenshots) <p><a href="image1.htm">Image1</a></p> <p><a href="image2.htm">Image2</a></p> <p><a href="image3.htm">Image3</a></p> <p><a href="image4.htm">Image4</a></p> <p><a href="image5.htm">Image5</a></p> </div> When I mouse over the links, the status bar shows the reference as "http://webHostServer.com/image1.htm". If I click it I get a 404 error. I need the href to change to something like this when I mouse over it: "http://www.actualImageHostServerIPaddress/image1.htm" I looked at this for assitance and came out with the following jQuery code, but for some reason none of it works: $(document).ready(function(){ $("button").click(function() { $("#screenshots a").addClass('ss'); }); $(".ss").each(function() { $(this).data("oldHref", $(this).attr("href")); orig = $(this).attr("href"); over = "http://208.167.244.33/208.167.244.33/"; $(this).hover(function() { $(this).attr("href", $(this).attr("href").replace(orig, over+orig)); }, function() { $(this).attr("href", $(this).data("oldHref")); }); }); When I click the button it dosen't add the class to the anchor tags, so when I hover over them nothing changes. Any help here would be great.

• iPhone -trouble with a loading data from webservice into a tableview

  - by medampudi

  I am using a Window based application and then loading up my initial navigationview based controller. After loading it if the user is not registered/ does not have a credentials present then it takes the user to a login view controller . loginViewController *sampleView = [[loginViewController alloc] initWithNibName:@"loginViewController" bundle:nil]; [self.navigationController presentModalViewController:sampleView animated:YES]; [sampleView release]; then right after that i try to load the table with data that i get from a webservice using asiHTTP .. for this question lets say it takes 3 seconds time to get the data and then deserialize it . now... my question is it works out okey in the later runs as I store the username and password in a seure location... but in the first instance.... i am not able to get the data to laod to the tableview... I have tried a lot of things... 1. Initially the data fetch methods was in a diffrent methods.. so i thought that might be the problem as then moved it the same place as the tbleviewController(navigationController) 2. I event put in the Reload data at the end of the functionality for the data parsing and deserialization... nothing happens. 3. i did not understand the concept of @property and alll.... 4. The screen is black screen with nothing displayed on it for a good 5 seconds in the consecutive launches of the app.... so could we have something like a MBPorgressHUD implemented for the same. could any one please help for these scenarios and guidance as to what paths to take from here...

• How do I detect the colillison of components?

  - by Coupon22

  How do I detect the collision of components, specifically JLabels (or ImageIcons?)?I have tried this: add(test1); test1.setLocation(x, y); add(test2); test1.setLocation(x1, y1); validate(); if(intersects(test1, test2)) { ehealth-=50; } public boolean intersects(JLabel testa, JLabel testb) { boolean b3 = false; if(testa.contains(testb.getX(), testb.getY())) { b3 = true; } return b3; } When I run this, it does nothing! I used to use rectangle, but it didn't go well with me. I was thinking about an image with a border (using paint.net) and moving an imageicon, but I don't know how to get the x of an imageicon or detect collision. I don't know how to detect collision of a label or increase the location either. I have searched for collision detection with components/ImageIcons, but nothing has came up. I have also searched for getting the x of ImageIcons.

• How to configure an index.htm file in IIS?

  - by salvationishere

  I am running IIS 6.0 on an XP OS using VS 2008 and SQL Server 2008 (Full install). I developed two web apps. Both of these I can run from IIS by setting them to the default website. However, now I tried adding an index.htm file. Real simple; all it has is two hyperlinks to these web apps. But now only the first web app works. The first web app is pure VS. The second web app modifies an Adventureworks database table. But now when I click the hyperlink for the second web app, it gives me the error below. However this error doesn't make sense to me cause I have the two web apps configured as two virtual directories beneath C:\inetpub\ and the index.htm file is also beneath C:\inetpub. And the default website is set to home directory C:\inetpub\ with Document index.htm on top. Also, why does the first web app work and not the second now? Server Error in '/AddFileToSQL' Application. The path '/AddFileToSQL/App_GlobalResources/' maps to a directory outside this application, which is not supported. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

• Home based business would like customers to schedule via website the time, day and date they want to take a class.

  - by Alessandro Machi

  I'm using google blogger. I want to ad thumbnail images of different classes I will be offering in my home film/video/sound/lighting studio. The idea is the prospective student visits my website, sees a class they want to take, clicks the thumbnail so first read a descriptive article about the class, at which point they can schedule the class for the time, day, and date of their choosing between the hours of 5am to 9pm, 365 days a year. As soon as the student has inputed the time, day and date of the class they want, they would go to a check out page to purchase the class time. The student would then be sent an email confirmation along with the exact location, the class name, and the time and date they selected. I was thinking of using Dwolla for the check out page because Dwolla offers either no fee or 25 cents per payment transaction, but I'm not sure I can hook up to them easily enough. My blog site is not finished by a longshot. I still have to actually input all of the class thumbnail images along with descriptions, but if you need to see what the page looks like the web address is http://www.myalexlogic.com Google blogger allows for third party code to be added within movable gadgets.

• Counting XML elements in file on Android

  - by CSharperWithJava

  Take a simple XML file formatted like this: <Lists> <List> <Note/> ... <Note/> </List> <List> <Note/> ... <Note/> </List> </Lists> Each node has some attributes that actually hold the data of the file. I need a very quick way to count the number of each type of element, (List and Note). Lists is simply the root and doesn't matter. I can do this with a simple string search or something similar, but I need to make this as fast as possible. Design Parameters: Must be in java (Android application). Must AVOID allocating memory as much as possible. Must return the total number of Note elements and the number of List elements in the file, regardless of location in file. Number of Lists will typically be small (1-4), and number of notes can potentially be very large (upwards of 1000, typically 100) per file. I look forward to your suggestions.

• JSON to javaScript array

  - by saturn_research

  I'm having a problem handling JSON data within JavaScript, specifically in regards to using the data as an array and accessing and iterating through individual values. The JSON file is structured as follows: { "head": { "vars": [ "place" , "lat" , "long" , "page" ] } , "results": { "bindings": [ { "place": { "type": "literal" , "value": "Building A" } , "lat": { "datatype": "http://www.w3.org/2001/XMLSchema#float" , "type": "typed-literal" , "value": "10.3456" } , "long": { "datatype": "http://www.w3.org/2001/XMLSchema#float" , "type": "typed-literal" , "value": "-1.2345" } , "page": { "type": "uri" , "value": "http://www.example.com/a.html" } } , { "place": { "type": "literal" , "value": "Building B" } , "lat": { "datatype": "http://www.w3.org/2001/XMLSchema#float" , "type": "typed-literal" , "value": "11.3456" } , "long": { "datatype": "http://www.w3.org/2001/XMLSchema#float" , "type": "typed-literal" , "value": "-2.2345" } , "page": { "type": "uri" , "value": "http://www.example.com/b.html" } } , { "place": { "type": "literal" , "value": "Building C" } , "lat": { "datatype": "http://www.w3.org/2001/XMLSchema#float" , "type": "typed-literal" , "value": "12.3456" } , "long": { "datatype": "http://www.w3.org/2001/XMLSchema#float" , "type": "typed-literal" , "value": "-3.2345" } , "page": { "type": "uri" , "value": "http://www.example.com/c.html" } } ] } } I want to be able to convert this into a JavaScript array as follows in order that I can iterate through it and pull out the values for each location in order: var locations = [ ['Building A',10.3456,-1.2345,'http://www.example.com/a.html'], ['Building B',11.3456,-2.2345,'http://www.example.com/b.html'], ['Building C',12.3456,-3.2345,'http://www.example.com/c.html'] ]; Does anyone have any advice on how to achieve this? I have tried the following, but it picks up the "type" within the JSON, rather than just the value: $.each(JSONObject.results.bindings, function(i, object) { $.each(object, function(property, object) { $.each(object, function(property, value) { value; }); }); }); Any help, suggestions, advice or corrections would be greatly appreciated.

Yes i have edit config file <?php /* Start session and load library. */ session_start(); require_once('twitteroauth/twitteroauth.php'); require_once('config.php'); /* Build TwitterOAuth object with client credentials. */ $connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET); /* Get temporary credentials. */ $request_token = $connection->getRequestToken(OAUTH_CALLBACK); /* Save temporary credentials to session. */ $_SESSION['oauth_token'] = $token = $request_token['oauth_token']; $_SESSION['oauth_token_secret'] = $request_token['oauth_token_secret']; /* If last connection failed don't display authorization link. */ switch ($connection->http_code) { case 200: /* Build authorize URL and redirect user to Twitter. */ $url = $connection->getAuthorizeURL($token); header('Location: ' . $url); break; default: /* Show notification if something went wrong. */ echo 'Could not connect to Twitter. Refresh the page or try again later.'; } I have enable php session on my ubuntu server, because this code works <?php session_start(); $_SESSION["secretword"] = "hello there"; $secretword = $_SESSION["secretword"] ; ?> <html> <head> <title>A PHP Session Example</title> </head> <body> <?php echo $secretword; ?> </body> </html>

• What could trigger a change of http status to 500 on the client's end?

  - by VexedPanda

  We have a PHP web application that posts data to itself, and either displays an updated page based on that data, or redirects to another page. An example of this is a script with a paged list on it, where clicking on the Next link causes a post to the same page, which then returns an updated version of the page showing the new set of list items. One client is reporting that IE is displaying friendly error messages when the page updates itself instead of the correct behavior of displaying the updated page. Turning friendly error messages off "corrects" this problem, and displays the updated page normally, indicating no actual server error occurred. When testing from any location other than this client's our web app does not produce any http error statuses, and in this specific situation only produces 200 statuses. (According to Fiddler.) What could be interfering with the HTTP POST and changing the response's http status code to 500 (or another code that would trigger friendly errors in IE)? Are there certain proxies or other network tools that could be misconfigured or buggy in this manner? Is there any way we can alter our application (apart from avoiding posts to the same script, which is not feasible) to get around this misbehavior?

• trouble calculating offset index into 3D array

  - by Derek

  Hello, I am writing a CUDA kernel to create a 3x3 covariance matrix for each location in the rows*cols main matrix. So that 3D matrix is rows*cols*9 in size, which i allocated in a single malloc accordingly. I need to access this in a single index value the 9 values of the 3x3 covariance matrix get their values set according to the appropriate row r and column c from some other 2D arrays. In other words - I need to calculate the appropriate index to access the 9 elements of the 3x3 covariance matrix, as well as the row and column offset of the 2D matrices that are inputs to the value, as well as the appropriate index for the storage array. i have tried to simplify it down to the following: //I am calling this kernel with 1D blocks who are 512 cols x 1row. TILE_WIDTH=512 int bx = blockIdx.x; int by = blockIdx.y; int tx = threadIdx.x; int ty = threadIdx.y; int r = by + ty; int c = bx*TILE_WIDTH + tx; int offset = r*cols+c; int ndx = r*cols*rows + c*cols; if((r < rows) && (c < cols)){ //this IF statement is trying to avoid the case where a threadblock went bigger than my original array..not sure if correct d_cov[ndx + 0] = otherArray[offset]; d_cov[ndx + 1] = otherArray[offset] d_cov[ndx + 2] = otherArray[offset] d_cov[ndx + 3] = otherArray[offset] d_cov[ndx + 4] = otherArray[offset] d_cov[ndx + 5] = otherArray[offset] d_cov[ndx + 6] = otherArray[offset] d_cov[ndx + 7] = otherArray[offset] d_cov[ndx + 8] = otherArray[offset] } When I check this array with the values calculated on the CPU, which loops over i=rows, j=cols, k = 1..9 The results do not match up. in other words d_cov[i*rows*cols + j*cols + k] != correctAnswer[i][j][k] Can anyone give me any tips on how to sovle this problem? Is it an indexing problem, or some other logic error?

• How to convert a rectangle to TRBL CSS rect value?

  - by VLostBoy

  I'm not quite sure how to put this, but here goes... The css clip attribute is defined like so: rect(top, right, bottom, left). However, I'm exploring the use of a custom Rectangle 'class' to encapsulate some operations. The rectangle class has the attributes height, width and x, y. The x and y values are encapsulated in a Point object, and the height and width are encapsulated in a Dimension object, the rectangle being a composite of a point (its top-left location) and a dimension (width and height). So far so good. I though it would be pretty simple on the basis of having the rectangles x, y, width and height values to define the css rect attribute in terms of top, right, bottom, left, but I've become hopelessly confused- I've been googling for a while, and I can't seem to find any documentation as to what the TRBL values actually are or what they represent. For example, should I be thinking in terms of co-ordinates, in which case, surely I can describe the rectangle as a css rect using the rectangles x position for Top, x position + width for Right, the rectangles height + y for Bottom and its y position for Left... but thats a load of BS, surely? Also, surely rect is actually an inset, or have I just inverted my understanding of clip? I'd appreciate some advice. What I want to be able to do is (i) Define a rectangle using x, y, width and height (ii)Express the rectangle in TRBL form so that I can manipulate a divs clipping behaviour (iii)Change x, y, width or height and recalculate in terms of TRBL and goto (ii) I appreciate there are some other factors here, and some intermediary transforms to be done, but I've confused myself pretty badly- Can anyone give me some pointers?

• [javascript] Populating jsTree based on XML data uploaded to server folder

  - by PFM

  tl:dr How can I populate jsTree based on a folder location instead of an exact XML url? I'm looking for a little direction on this project. Currently I am trying to copy file structures of hard drives as XML files and recreate them using jsTree on the webserver for a completely independent version of the file structure. I have some python script that outputs XML files that are formed to jsTree and automatically uploads to a folder on the server. The problem is now I am a little lost because I have to manually enter each XML file into jsTree code for it to display so I have multiple entries like this: $("#tree1") .jstree({ "plugins" : [ "themes", "xml_data", "ui", "search", "types" ], "xml_data" : { "ajax" : { "url" : "./XML_DATA/DRIVE1.xml" }, "xsl" : "nest" }, I see in the documentation that instead of populated by the direct file the folders are populated by "server.php" but no where in the php code does it point to any directories or files. After considering the problem I thought of a few solutions and could use some advice on them: Should I be trying to write php code to automatically look through my XML_DATA folder to upload each XML file? Should I just upload all the XML to mySQL and populate my tree based on that? Should the javascript be the code looking through the server's folder for XML files? All the XML is formed the same way but the number of XML files on the server will increase and will have to be refreshed as well as they will be overwritten with changes. Any direction would be appreciated, thanks.
