• Silverlight Pixel Shader resource "not found"; what should the URI be?

  - by Grank

  So I've written and compiled an HLSL pixel shader with Shazzam, placed the resulting .ps file in my project, and am trying to instantiate it. No matter what URI I put, Blend tells me that the resource can't be found whenever I try to view any xaml designer, and Visual Studio just shows me a blank page, both in design view and if I try to run the application. This is a Silverlight 4 SketchFlow project, in Blend 4 RC and Visual Studio 2010. I've tried both Resource and EmbeddedResource as the Build Action for the .ps file, neither make any difference (I'm pretty sure it's supposed to be set to Resource). I've tried the following URI formats: "ShaderFileName.ps" "/ShaderFileName.ps" "AssemblyName;component/ShaderFileName.ps" "/AssemblyName;component/ShaderFileName.ps" I also tried moving the shader file from the Screens assembly to the root assembly (that's how SketchFlow projects are created) and that didn't help either. Anyone have any thoughts?

• .net, using PowerShell class to invoke a "[namespace.class]::method" style command

  - by Marco

  Hello, I created a powershell object via .net to invoke commands. When I invoke normal commands like 'Get-Process' I had no problems: ps.AddCommand("Get-Process").AddParameter(...).Invoke() but I'm not able to invoke a .net method with the syntax "[namespace.class]::method", just to make an example to invoke [System.IO.File]::Exists("c:\boo.txt"). I tried with ps.AddCommand("[System.IO.File]::Exists(\"c:\boo.txt\")").Invoke() ps.AddCommand("[System.IO.File]::Exists").AddArgument("c:\boo.txt\").Invoke() and some others. It always throws an exception which says that the command specified is not recognized. There is a way to invoke that type of command? Thanks

• getResourceAsStream not loading resource in webapp

  - by mangst

  I have a web application that uses a library which resides in TOMCAT_HOME/common/lib. This library looks for a properties file at the root of the classpath (in a class called ApplicationConfig): ApplicationConfig.class.getResourceAsStream("/hv-application.properties"); My Tomcat web application contains this properties file. It is in WEB-INF/classes, which is the root of the classpath right? However, at runtime, when it tries to load the properties file, it throws an exception because it can't find it (getResourceAsStream returns null). Everything works fine if my application is a simple, standalone Java application. Does Tomcat cause the getResourceAsStream method to act differently? I know there's a lot of similar questions out there, but none of them have helped unfortunately. Thanks.

• How to specify a web service URL within a Drupal module's simpletest?

  - by Matt V.

  I have a Drupal module that talks to a REST API on a separate server for user registration and authentication. The module runs on multiple sites which point to different servers which may run different versions of the REST API. Ideally, I'd like to be able to run each site against its own end-point, in case changes on the back end break things. Is there a way to dynamically specify a different end-point URL when running a test? Or do I have to edit the .test file for each site? I'm trying to keep the module's files as generic and flexible as possible. I guess I could have the .test file look for a .inc file that could override the URL, if needed for a particular site. Is there a better way though?

• using KVO to filter an NSTableView using NSPredicate (with arrays)

  - by KingRufus

  My UI is not updating when I expect it to. The application displays "projects" using a view similar to iTunes -- a source list on the left lets you filter a list (NSTableView) on the right. My filters update properly when they are examining any simple field (like name, a string), but not for arrays (like tags). I'm removing a tag from one of my objects (from an NSMutableArray field called "tags") and I expect it to disappear from the list because it no longer matches the predicate that is bound to my table's NSArrayController. ProjectBrowser.mm: self.filter = NSPredicate* srcPredicate = [NSPredicate predicateWithFormat:@"%@ IN %K", selectedTag, @"tags"]; Project.mm: [self willChangeValueForKey:@"tags"]; [tags removeAllObjects]; [self didChangeValueForKey:@"tags"]; I've also tried this, but the result is the same: [[self mutableArrayValueForKey:@"tags"] removeAllObjects]; Interface Builder setup: a ProjectBrowser object is the XIB's File Owner an NSArrayController (Project Controller) has its Content Array bound to "File's Owner".projects Project Controller's filter predicate is bound to "File's Owner".filter NSTableView's column is bound to "Project Controller".name

• How do I get a reference to the current project in an Eclipse plugin?

  - by Martin Doms

  I'm creating an editor for Eclipse. Right now the editor fires up with the user creates a new file with the appropriate extension. My question is, how can I get a reference to the project in which the file resides? For example, say I have a workspace with 2 projects, P1 and P2. I right click P2 and create a new file, can I get a reference to P2 from this somehow? Ultimately I need to reference the AST or Java Model of the project but even a String identifying the project would work.

• Integer output in Java method not same as pre-converted char value.

  - by David

  I'm trying to parse a simple text file in an integer method and then output an integer from such file so that other parts of the program can use it. For testing purposes it also displays the character value (9 in this case). The integer value for some reason is 57. I've also tried it with another part of the text file (which in that case should be 5, but is instead 53). After looking at an ASCII chart, I see that 57 is the ASCII version of the "symbol" 9 and that 53 is the ASCII version of the "symbol" 5. Is there any simple way I can fix this? I'm getting kind of frustrated as I'm a Java newbie (I've mostly only used FreePascal before this).

• amazon design doubt

  - by praveen

  I was looking at the amazon website and was wondering how one of the feature would have been implemented. The feature : what customers buy after viewing a particular item. If i were to develop such a feature i would probably generate a session id for each user session and store the session id-page id combination in a log file. and if a book is bought set a separate flag for the session id-page id. A separate program can then be run on the log file periodically, to identify the groups that were bought together/viewed together and that information can be stored in a persistent file. This is ofcourse a simple solution without taking into consideration the distributed nature of the servers - but would this suffice or can you help me identify a better design.

• Compression Array of Bytes

  - by Pedro Magalhaes

  Hi, My problem is: I want to store a array of bytes in compressed file, and then I want to read it with a good performance. So I create a array of bytes then pass to a ZLIB algorithm then store it in the file. For my surprise the algorithm doesn't work well., probably because the array is a random sample. Using this approach, it will will be ber easy to read. Just copy the stream to memory, decompress them and copy it to a array of bytes. But i need to compress the file. Do I have to use a algorithm, like RLE, for compresse the byte array? I think that I can store the byte array like a string and then compress it. But i think I am going to have a poor performance on reading data. Sorry for my poor english. Thanks

• Version control of Mathematica notebooks

  - by Etaoin

  Mathematica notebooks are, of course, plaintext files -- it seems reasonable to expect that they should play nice with a version-control system (git in my case, although I doubt the specific system matters). But the fact is that any .nb file is full of cache information, timestamps, and other assorted metadata. Scads of it. Which means that limited version control is possible -- commits and rollbacks work fine. Merging, though, is a disaster. Mathematica won't open a file with merge markers in it, and a text editor is no way to go through a .nb file. Has anyone had any luck putting a notebook under version control? How?

• accessing required modules from other modules

  - by john smith

  I have a bare-bone express application, exactly the one that is created with the express command. I have installed socket.io and attached it to my server, like this: var app = express(), server = http.createServer(app), io = io.listen(server); server.listen(8000); Now, I also have the routes files, which is called like this: app.get('/', routes.index); Inside this module I have the following function: exports.index = function(req, res){ socket.emit('news', { message: "foo" }); }; This obviously leads to a 500 reference error, because the routes file is an exportable module, and obviously has no idea what the socket is, as it is located in the app.js file. Is there a way I can access this socket object from this, or any other file? Please note that it is attached to the express generated app. extra: what about getting/setting session data? Thanks in advance.

• Security sandbox violation when connecting to Socket from flex

  - by KensoDev

  Hi, I am using a Socket (not xmlSocket) connection between flex applications and the server pushing messages. Now, when I connect from the local machine to the server everything is working file and running, connection is succesful and I get data back and forth. When I upload the application (flex) to the server and run it from there, I get a security sandBox violation message. Note: 1. I do have a crossdomain file with * wildcard both on port and on domain. 2. I created a Securiy.allowDomain("*") as well. Another thing. I also created another listener on that same server, listening to connections for port 843 (default) and this service just waited for a connection send policy file to the client and that's it. That did not solve the problem as well... That's next? What should I do to fix the problem? Appreciate your help. Avi

• Migrating a Core Data Store from iCloud to local

  - by schmok

  I'm currently struggling with Core Data iCloud migration. I want to move a store from an iCloud ubiquity container (.nosync) to a local URL. Problem is whenever I call something like this: NSPersistentStore *newStore = [self.persistentStoreCoordinator migratePersistentStore: currentiCloudStore toURL: localURL options: nil withType: NSSQLiteStoreType error: &error]; I get this error: -[NSPersistentStoreCoordinator addPersistentStoreWithType:configuration:URL:options:error:](1055): CoreData: Ubiquity: Error: A persistent store which has been previously added to a coordinator using the iCloud integration options must always be added to the coordinator with the options present in the options dictionary. If you wish to use the store without iCloud, migrate the data from the iCloud store file to a new store file in local storage. file://localhost/Users/sch/Library/Containers/bla/Data/Documents/tmp.sqlite. This will be a fatal error in a future release Anyone ever seen this error? Maybe I'm just missing the right migration options?

• Dreamweaver creating temp php files instead of working direct from the local test server files

  - by Dan382

  Trying to get MAMP running with Dreamweaver. When I preview a php file inside Dreamweavers 'Live View' mode instead of working direct from my file: http://localhost/php_test/timetest.php it creates its own temp file which looks like: http:// 127.0.0.1/php_test/ TMPWY5ZEM.php (I've added the additional spaces as stockoverflow assumed I was spamming) I know the localhost runs correctly as if I type the URL directly into a browser it runs fine. I've set up the Dreamweaver site correctly to the best of my knowledge, the details are below: Local site folder: /Applications/MAMP/htdocs/php_test Server Folder: /Applications/MAMP/htdocs/php_test Web URL: http://localhost/php_test/ Testing Server: PHP MySQL Any help?

• Downloaded chm is blocked, is there a solution?

  - by David Rutten

  CHM files that are downloaded are often tagged as potentially malicious by Windows, which effectively blocks all the html pages inside of it. There's an easy fix (just unblock the file after you download it), but I was wondering if there's a better way to provide unblocked chm files. What if I were to download the chm file (as a byte stream) from our server inside the application, then write all the data to a file on the disk. Would it still be blocked? Is there another/better way still?

• PHP Export to CSV

  I'm not really familiar with PHP exporting to excel or csv, but I'm using PHP MySQL for a local point of sale. According to the code below, this actually works..But not in the way it should be ! All records are placed as 1 row inside the csv file, how can i fix that ? Also, How would I stop overwriting the same file...I mean When I click on a Button to export the csv, it should check if there is an existing csv file, If there is--Create new one ! Thank You require_once('connect_db.php'); $items_array = array(); $result = mysql_query("SELECT * FROM sold_items"); while($row = mysql_fetch_array($result)) { $items_array[] = $row['item_no']; $items_array[] = $row['qty']; } $f = fopen('C:/mycsv.csv', 'w'); fputcsv($f, $items_array); fclose($f);

• How can I compare Core Data models?

  - by Don

  I noticed while doing system testing that a feature of our app had been removed. It looks like at some point, an older version of a file was checked into SVN that was missing a property. This specific file was generated from the Core Data model, and sure enough, the latest version of the model in SVN is missing the same attribute. I need to find out if any other attributes are missing, or if anything else in the model changed. However, the elements file in the .xcodedatamodel folder appears to binary and I can't compare the revisions. Is there a way to find the differences between two Core Data models in SVN? Barring that, what would be the best way to accomplish this task?
