  • Is it possible to transcode audio in C# using DirectSound?

    - by Robert Davis
    I want to transcode a lot of audio from its source format to PCM without resampling or messing with the sample size. I figure if Windows Media Player can play the file and it doesn't use a legacy ACM codecs it must be using DirectSound to do so (this is on Windows XP and Windows Server 2k3). So is it possible to access DirectSound from C# and do so? I've tried searching the web but all the examples have been about playback which I have no interest in doing.

  • Serializing data from a RSS feed in ASP.NET/C#

    - by DotnetDude
    I'd like the user to specify a RSS feed address and serialize the information from it. I am not interested in the XML format, but populate a strongly typed object from the XML. My question is, is there a standard that all RSS feeds support (Do all of them have date, title etc)? If so, is there a XSD that describes this. If not, how do I handle serializing a RSS feed to an object in ASP.NET?

  • How to extract Twitter username from Search API via PHP

    - by Alexia
    The Twitter Search api returns results in ATOM/XML format which look like this: <author> <name>username (Friendly Name)</name> <uri>http://twitter.com/username</uri> </author> In my PHP I can get the name field as a variable, so it would look like this: $names = "username (Friendly Name)" But I want to use PHP to extract them as seperate variables, like this: $username = "username" $friendlyName = "Friendly Name" (without parantheses) TIA!

  • FireBird .net provider 64bit

    - by Lavinski
    I'm trying to get a firebird web application (IIS6 64 bit) to run. However I'm getting bad image format (bit difference incompatability) issues. Has anyone got any advice to get it running. Details AnyCPU application references the .net firebird driver (through nhibernate) which uses a native 64bit dll. There is a native 32bit dll which I use for local development and it works fine. (I havn't got the 32 version working on the 64 bit server either).

  • How can I open VLC via browser with PHP (Mac OS X)

    - by Damiqib
    I'm trying to open VLC via browser and make it instantly play the given video file on Mac OS X. This runs on my local server and is only meant to run locally - therefore I already run apache (MAMP) with my username and with group "staff" (defined in httpd.conf). YES - I do know that VLC has http interface - however that is not what I need, so do not suggest that... My current system works without any problems when I run it via Terminal: php /var/www/Movies/index.php - This leads to VLC opening and video starts playing fullscreen like intented. Problems start when I run the same PHP-page with browser. Then the VLC-process starts, but there's no GUI for it, video file won't start playing and the VLC-process takes nearly 100% of CPU. Both; terminal and browser started VLC-processes run with the same user (mine) Both have "Parent process" bash VLC-process begun with Terminal has empty "Process group" (only process id-number) and browser started has "httpd" + (id-number) VLC-process started via browser makes 1000-times more "Mach System Calls" than it's Terminal-started counterpart. Could anyone give me any pointers on how to get this thing working? index.php # $j is a file path to the videofile and is defined before exec('/var/www/Movies/vlc.sh "' . $j . '" > /dev/null 2>&1 & echo $!;'); # If I do this in the given PHP-page it tells me that apache is running # with my username and with the group "staff" like it should be... exec('whoamI'); vlc.sh #!/bin/bash # Activate VLC in 5 seconds to make it the front-most window (sleep 5; open -a VLC) & # Open video file /Applications/VLC.app/Contents/MacOS/VLC --quiet --fullscreen "$1"

  • How to scan an array for certain information

    - by Andrew Martin
    I've been doing an MSc Software Development conversion course, the main language of which is Java, since the end of September. We have our first assessed practical coming and I was hoping for some guidance. We have to create an array that will store 100 integers (all of which are between 1 and 10), which are generated by a random number generator, and then print out ten numbers of this array per line. For the second part, we need to scan these integers, count up how often each number appears and store the results in a second array. I've done the first bit okay, but I'm confused about how to do the second. I have been looking through the scanner class to see if it has any methods which I could use, but I don't see any. Could anyone point me in the right direction - not the answer, but perhaps which library it comes from? Code so far: import java.util.Random; public class Practical4_Assessed { public static void main(String[] args) { Random numberGenerator = new Random (); int[] arrayOfGenerator = new int[100]; for (int countOfGenerator = 0; countOfGenerator < 100; countOfGenerator++) arrayOfGenerator[countOfGenerator] = numberGenerator.nextInt(10); int countOfNumbersOnLine = 0; for (int countOfOutput = 0; countOfOutput < 100; countOfOutput++) { if (countOfNumbersOnLine == 10) { System.out.println(""); countOfNumbersOnLine = 0; countOfOutput--; } else { System.out.print(arrayOfGenerator[countOfOutput] + " "); countOfNumbersOnLine++; } } } } Thanks, Andrew

  • question about that concept of linux install in flash card.

    - by Johnny
    1.i can't understand why Linux on flash card need install, does it simply copy certain file to certain location in flash card? ---i mean ,plan it in a response file,then one program read the plan in response file and write certain format to flash card. 2.does the file system bind tiedly to the linux kernel? is it possible let each kernel,user,app have its own root? rather than mount everything under one single / "root"

  • Splitting up UDP packet

    - by m3n
    Heyo, I'm using UdpClient to query game servers about server name, map, number of players, etc. I've followed the guidelines on this page http://developer.valvesoftware.com/wiki/Server_queries#Source_servers and I'm getting a correct reply: I have no idea how I would go about to get each chunk of information (server name, map and the like). Any help? I'm assuming one would have to look at the reply format specified in the wiki I linked, but I don't know what to make of it. Cheers,

  • On linux, what can cause dlopen to emit SIGFPE?

    - by kdt
    I have a library of dubious origins which is identified by file as a 32 bit executable. However, when I try to dlopen it on a 32 bit CentOS 4.4 machine, dlopen terminates with SIGFPE. Surely if there was something wrong with the format of the binary then dlopen should be handling an error? So the question is: What kinds of problems can cause dlopen to emit SIGFPE?

  • How do I programmatically insert rows into a Silverlight DataGrid without binding?

    - by j0rd4n
    I am using a common Silverlight DataGrid to display results from a search. The "schema" of the search can vary from query to query. To accommodate this, I am trying to dynamically populate the DataGrid. I can set explicitly set the columns, but I am having trouble setting the ItemSource. All of the MSDN examples set the ItemSource to a collection with a strong type (e.g. a Custom type with public properties matching the schema). The DataGrid then uses reflection to scour the strong type for public properties that will match the columns. Since my search results are dynamic, I cannot create a strong type to represent what comes back. Can I not just give the DataGrid an arbitrary list of objects so long as the number of objects in each list matches the number of columns? Anyone know if this is possible? I would like to do something similar to this: List<List<object>> myResults = <voodoo that populates the result list> myDataGrid.ItemsSource = myResults;

  • How to use a linkedList and multiple classes with my Java GUI

    - by Asj
    How should I use a linked list with my GUI program? The program is supposed to have blocks with textareas and dropdown menus. The number of blocks depends on the number of times the user presses a button. It's supposed to be possible to put blocks within blocks. I want to store the information created, using a linked list and then saving to a file. I'm thinking, for the sub blocks, there would be linked lists within the linked list. Should I use Java.util.LinkedList? How do I add the information? A Node class? Should that be in a separate file? I started to try sitting up a linked list, but it's getting me confused. I'm still unsure about how a person is supposed to make GUI's. I've only seen really simple GUI's. Can anyone tell me how I should arrange things? At the moment, I have three files, one for the main GUI window, one for the question blocks to be inserted within that, and one for some tools to use within those two files to make the code easier to understand. But, there seems to be something wrong with the question block file, because I've been making the background white for each JPanel, and there's a gray outline around the question blocks when I run the program. I probably shouldn't paste a ton of code here... These are my files: http://asj127.webs.com/BuildAssessmentWindow.java http://asj127.webs.com/QuestionBlock.java http://asj127.webs.com/JPanelTools.java

  • Regular expression to extract text between either square or curly brackets

    - by ObiWanKenobi
    Related to my previous question, I have a string on the following format: this {is} a [sample] string with [some] {special} words. [another one] What is the regular expression to extract the words within either square or curly brackets, ie. {is} [sample] [some] {special} [another one] Note: In my use case, brackets cannot be nested. I would also like to keep the enclosing characters, so that I can tell the difference between them when processing the results.

  • UICollectionView with one static cell and N dynamic ones from a fetchresultscontroller exception

    - by nflacco
    I'm trying to make a UITableView that shows a blog post and comments for that post. My setup is a tableview in storyboard with two dynamic prototype cells. The first cell is for the post and should never change. The second cell represents the 0 to N comments. My cellForRowAtIndexPath method shows the post cell properly, but fails to get the comment at the given index path (though if I comment out the fetch I get the appropriate number of comment cells with a green background that I set as a visual debug thing). let comment = fetchedResultController.objectAtIndexPath(indexPath) as Comment I get the following exception on this line: 2014-08-24 15:06:40.712 MessagePosting[21767:3266409] *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 1 beyond bounds [0 .. 0]' *** First throw call stack: ( 0 CoreFoundation 0x0000000101aa43e5 __exceptionPreprocess + 165 1 libobjc.A.dylib 0x00000001037f9967 objc_exception_throw + 45 2 CoreFoundation 0x000000010198f4c3 -[__NSArrayM objectAtIndex:] + 227 3 CoreData 0x00000001016e4792 -[NSFetchedResultsController objectAtIndexPath:] + 162 Section and cell setup: override func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int { // #warning Incomplete method implementation. // Return the number of rows in the section. switch section { case 0: return 1 default: if let realPost:Post = post { return fetchedResultController.sections[0].numberOfObjects } else { return 0 } } } override func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! { switch indexPath.section { case 0: let cell = tableView.dequeueReusableCellWithIdentifier(postViewCellIdentifier, forIndexPath: indexPath) as UITableViewCell cell.backgroundColor = lightGrey if let realPost:Post = self.post { cell.textLabel.text = realPost.text } return cell default: let cell = tableView.dequeueReusableCellWithIdentifier(commentCellIdentifier, forIndexPath: indexPath) as UITableViewCell cell.backgroundColor = UIColor.greenColor() let comment = fetchedResultController.objectAtIndexPath(indexPath) as Comment // <---------------------------- :( cell.textLabel.text = comment.text return cell } } FRC: func controllerDidChangeContent(controller: NSFetchedResultsController!) { tableView.reloadData() } func getFetchedResultController() -> NSFetchedResultsController { fetchedResultController = NSFetchedResultsController(fetchRequest: taskFetchRequest(), managedObjectContext: managedObjectContext, sectionNameKeyPath: nil, cacheName: nil) return fetchedResultController } func taskFetchRequest() -> NSFetchRequest { if let realPost:Post = self.post { let fetchRequest = NSFetchRequest(entityName: "Comment") let sortDescriptor = NSSortDescriptor(key: "date", ascending: false) fetchRequest.predicate = NSPredicate(format: "post = %@", realPost) fetchRequest.sortDescriptors = [sortDescriptor] return fetchRequest } else { return NSFetchRequest(entityName: "") } }

  • How to output formatted HTML from PHP?

    - by Tim
    I like to format all my HTML with tabs for neatness and readability. Recently I started using PHP and now I have a lot of HTML output that comes from in between PHP tags. Those output lines all line up one the left side of the screen. I have to use /n to make a line go to the next. Is there anything like that for forcing tabs, or any way to have neat HTML output coming from PHP?

  • Java object to XML Elements?

    - by DaveKub
    I'm working on a webservices client app and I have it mostly working. I can retrieve and read data from the third-party webservice fine. Now I need to submit some data and I'm stuck. The classes for the objects I'm retrieving/submitting were generated from XSD files via the xjc tool. The part I'm stuck on is turning one of those objects into an XML tree to submit to the webservice. When I retrieve/send a request from/to the ws, it contains a 'payload' object. This is defined in java code as (partial listing): @XmlAccessorType(XmlAccessType.FIELD) @XmlType(name = "PayloadType", propOrder = { "compressed", "document", "any", "format" }) public class PayloadType { @XmlElement(name = "Compressed") protected String compressed; @XmlElement(name = "Document") protected List<String> document; @XmlAnyElement protected List<Element> any; protected String format; public List<Element> getAny() { if (any == null) { any = new ArrayList<Element>(); } return this.any; } } The only field I'm concerned with is the 'any' field which contains an XML tree. When I retrieve data from the ws, I read that field with something like this: ('root' is of org.w3c.dom.Element type and is the result of calling 'getAny().get(0)' on the payload object) NodeList nl = root.getElementsByTagName("ns1:Process"); // "ns1:Process" is an XML node to do something with if (nl != null && nl.getLength() > 0) { for (int i = 0; i < nl.getLength(); i++) { Element proc = (Element) nl.item(i); try { // do something with the 'proc' Element here... } catch (Exception ex) { // handle problems here... } } } Submitting data is where I'm stuck. How do I take a java object created from one of the classes generated from XSD and turn it into an Element object that I can add to the 'any' List of the payload object?? For instance, if I have a DailyData class and I create and populate it with data: DailyData dData = new DailyData(); dData.setID = 34; dData.setValues = "3,5,76,23"; How do I add that 'dData' object to the 'any' List of the payload object? It has to be an Element. Do I do something with a JAXBContext marshaller? I've used that to dump the 'dData' object to the screen to check the XML structure. I'm sure the answer is staring me in the face but I just can't see it! Dave
