  • Streaming local file from PHP while it's been written to by a CURL process

    - by Fahim
    I am creating a simple Proxy server for my website. Why I am not using mod_proxy and mod_cache is a different discussion. Here's the code: shell_exec("nohup curl --create-dirs -o {$write_path} {$source_url} > /dev/null 2> /dev/null & echo $!"); sleep(1); $read_speed = 65.5; # 65.5 kb/s download rate $handle = fopen($write_path, "rb"); $content_type = select_meta_item($headers, 'Content-Type'); $file_size = select_meta_item($headers, 'Content-Length'); send_headers($content_type, $file_size); flush(); while (!feof($handle)) { echo fread($handle, round($read_speed * 1024)); flush(); sleep(1); } fclose($handle); Streaming an MP3 doesn't work using this method. Plays in Chrome, but not in Firefox. Initially I'll be using this to stream MP3 files through Long Tail's JW Player. If it all works out, I'll also be using this to send ZIP files.

  • How to File Transfer client to Server?

  • Core Audio on iPhone - any way to change the microphone gain (either for speakerphone mic or headpho

    - by Halle
    After much searching the answer seems to be no, but I thought I'd ask here before giving up. For a project I'm working on that includes recording sound, the input levels sound a little quiet both when the route is external mic + speaker and when it's headphone mic + headphones. Does anyone know definitively whether it is possible to programmatically change mic gain levels on the iPhone in any part of Core Audio? If not, is it possible that I'm not really in "speakerphone" mode (with the external mic at least) but only think I am? Here is my audio session init code: OSStatus error = AudioSessionInitialize(NULL, NULL, audioQueueHelperInterruptionListener, r); [...some error checking of the OSStatus...] UInt32 category = kAudioSessionCategory_PlayAndRecord; // need to play out the speaker at full volume too so it is necessary to change default route below error = AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(category), &category); if (error) printf("couldn't set audio category!"); UInt32 doChangeDefaultRoute = 1; error = AudioSessionSetProperty (kAudioSessionProperty_OverrideCategoryDefaultToSpeaker, sizeof (doChangeDefaultRoute), &doChangeDefaultRoute); if (error) printf("couldn't change default route!"); error = AudioSessionAddPropertyListener(kAudioSessionProperty_AudioRouteChange, audioQueueHelperPropListener, r); if (error) printf("ERROR ADDING AUDIO SESSION PROP LISTENER! %d\n", (int)error); UInt32 inputAvailable = 0; UInt32 size = sizeof(inputAvailable); error = AudioSessionGetProperty(kAudioSessionProperty_AudioInputAvailable, &size, &inputAvailable); if (error) printf("ERROR GETTING INPUT AVAILABILITY! %d\n", (int)error); error = AudioSessionAddPropertyListener(kAudioSessionProperty_AudioInputAvailable, audioQueueHelperPropListener, r); if (error) printf("ERROR ADDING AUDIO SESSION PROP LISTENER! %d\n", (int)error); error = AudioSessionSetActive(true); if (error) printf("AudioSessionSetActive (true) failed"); Thanks very much for any pointers.

  • How I shoud use BIT in MS SQL 2005

    - by adopilot
    Regarding to SQL performance. I have Scalar-Valued function for checking some specific condition in base, It returns BIT value True or False, I now do not know how I should fill @BIT parameter If I write. set @bit = convert(bit,1) or set @bit = 1 or set @bit='true' Function will work anyway but I do not know which method is recommended for daily use. Another Question, I have table in my base with around 4 million records, Daily insert is about 4K records in that table. Now I want to add CONSTRAINT on that table whit scalar valued function that I mentioned already Something like this ALTER TABLE fin_stavke ADD CONSTRAINT fin_stavke_knjizenje CHECK ( dbo.fn_ado_chk_fin(id)=convert(bit,1)) Where is filed "id" primary key of table fin_stavke and dbo.fn_ado_chk_fin looks like create FUNCTION fn_ado_chk_fin ( @stavka_id int ) RETURNS bit AS BEGIN declare @bit bit if exists (select * from fin_stavke where id=@stavka_id and doc_id is null and protocol_id is null) begin set @bit=0 end else begin set @bit=1 end return @bit; END GO Will this type and method of cheeking constraint will affect badly performance on my table and SQL at all ? If there is also better way to add control on this table please let me know.

  • Problem Parsing JSON Result with jQuery

    - by senfo
    I am attempting to parse JSON using jQuery and I'm running into issues. In the code below, I'm using a static file, but I've also tested using an actual URL. For some reason, the data keeps coming back as null: <!DOCTYPE html> <html> <head> <title>JSON Test</title> <script src="http://code.jquery.com/jquery-latest.js"></script> <script> $.getJSON('results.json', function(data) { alert(data); // Result is always null }); </script> </head> <body> </body> </html> The JSON results look like the following: {"title":"HEALTHPOINT TYEE CAMPUS","link":"http://www.healthpointchc.org","id":"tag:datawarehouse.hrsa.gov,2010-04-29:/8357","org":"HEALTHPOINT TYEE CAMPUS","address":{"street-address":"4424 S. 188TH St.","locality":"Seatac","region":"Washington","postal-code":"98188-5028"},"tel":"206-444-7746","category":"Service Delivery Site","location":"47.4344818181818 -122.277672727273","update":"2010-04-28T00:00:00-05:00"} If I replace my URL with the Flickr API URL (http://api.flickr.com/services/feeds/photos_public.gne?tags=cat&tagmode=any&format=json&jsoncallback=?), I get back a valid JSON result that I am able to make use of. I have successfully validated my JSON at JSONLint, so I've run out of ideas as to what I might be doing wrong. Any thoughts?

  • Why should I bother with unit testing if I can just use integration tests?

    - by CodeGrue
    Ok, I know I am going out on a limb making a statement like that, so my question is for everyone to convince me I am wrong. Take this scenario: I have method A, which calls method B, and they are in different layers. So I unit test B, which delivers null as a result. So I test that null is returned, and the unit test passes. Nice. Then I unit test A, which expects an empty string to be returned from B. So I mock the layer B is in, an empty string is return, the test passes. Nice again. (Assume I don't realize the relationship of A and B, or that maybe two differente people are building these methods) My concern is that we don't find the real problem until we test A and B togther, i.e. Integration Testing. Since an integration test provides coverage over the unit test area, it seems like a waste of effort to build all these unit tests that really don't tell us anything (or very much) meaningful. Why am I wrong?

  • SQL Joins Excluding Data

    - by Andrew
    Say I have three tables: Fruit (Table 1) ------ Apple Orange Pear Banana Produce Store A (Table 2 - 2 columns: Fruit for sale => Price) ------------------------- Apple => 1.00 Orange => 1.50 Pear => 2.00 Produce Store B (Table 3 - 2 columns: Fruit for sale => Price) ------------------------ Apple => 1.10 Pear => 2.50 Banana => 1.00 If I would like to write a query with Column 1: the set of fruit offered at Produce Store A UNION Produce Store B, Column 2: Price of the fruit at Produce Store A (or null if that fruit is not offered), Column 3: Price of the fruit at Produce Store B (or null if that fruit is not offered), how would I go about joining the tables? I am facing a similar problem (with more complex tables), and no matter what I try, if the "fruit" is not at "produce store a" but is at "produce store b", it is excluded (since I am joining produce store a first). I have even written a subquery to generate a full list of fruits, then left join Produce Store A, but it is still eliminating the fruits not offered at A. Any Ideas?

  • Recommendations needed for email server and file sharing solutions.

    - by Abeansits
    I work at a relatively small company, around 30 people and we are now looking into a solution that can handle: File sharing. Email server. Calendar support. Around 30 users. Accessible from external network. Support for Windows XP (and above), Mac OS 10.6.3 and Ubuntu clients. When it comes down to security we don't have the experience to comment on that. I guess the de facto standard is good enough for us. Sorry if this is formulated as a n00b question, because it is. =) Any kind of pointer in the right direction will be appreciated. Thanks in advance! //Abean

  • Show PDF in HTML in web

    - by Anil
    Hi, I'm using the object tag to render PDF in HTML, but I'm doing it in MVC like this: <object data="/JDLCustomer/GetPDFData?projID=<%=ViewData["ProjectID"]%>&folder=<%=ViewData["Folder"] %>" type="application/pdf" width="960" height="900"> </object> and Controller/Action is public void GetPDFData(string projID, Project_Thin.Folders folder) { Highmark.BLL.Models.Project proj = GetProject(projID); List<File> ff = proj.GetFiles(folder, false); if (ff != null && ff.Count > 0 && ff.Where(p => p.FileExtension == "pdf").Count() > 0) { ff = ff.Where(p => p.FileExtension == "pdf").ToList(); Response.ClearHeaders(); Highmark.BLL.PDF.JDLCustomerPDF pdfObj = new JDLCustomerPDF(ff, proj.SimpleDbID); byte[] bArr = pdfObj.GetPDF(Response.OutputStream); pdfObj = null; Response.ContentType = "application/" + System.IO.Path.GetExtension("TakeOffPlans").Replace(".", ""); Response.AddHeader("Content-disposition", "attachment; filename=\"TakeOffPlans\""); Response.BinaryWrite(bArr); Response.Flush(); } } The problem is, as I'm downloading data first from server and then return the byte data, it is taking some time in downloading, so I want to show some kind of progress to show processing. Please help me on this.

  • Basic File upload in GWT

    - by Maksim
    I'm trying to figure out how to upload one file using GWTs FileUpload widget. I'm using GWT and Google AppEngine with Java but I would like to upload file to my own Linux server. I have the following code already but now I can't figure out how to submit my file to the Google AppServer server and save it to another server: public class FileUploader{ private ControlPanel cp; private FormPanel form = new FormPanel(); private FileUpload fu = new FileUpload(); public FileUploader(ControlPanel cp) { this.cp = cp; this.cp.setPrimaryArea(getFileUploaderWidget()); } @SuppressWarnings("deprecation") public Widget getFileUploaderWidget() { form.setEncoding(FormPanel.ENCODING_MULTIPART); form.setMethod(FormPanel.METHOD_POST); // form.setAction(/* WHAT SHOULD I PUT HERE */); VerticalPanel holder = new VerticalPanel(); fu.setName("upload"); holder.add(fu); holder.add(new Button("Submit", new ClickHandler() { public void onClick(ClickEvent event) { GWT.log("You selected: " + fu.getFilename(), null); form.submit(); } })); form.addSubmitHandler(new FormPanel.SubmitHandler() { public void onSubmit(SubmitEvent event) { if (!"".equalsIgnoreCase(fu.getFilename())) { GWT.log("UPLOADING FILE????", null); // NOW WHAT???? } else{ event.cancel(); // cancel the event } } }); form.addSubmitCompleteHandler(new FormPanel.SubmitCompleteHandler() { public void onSubmitComplete(SubmitCompleteEvent event) { Window.alert(event.getResults()); } }); form.add(holder); return form; } } Now, what do I need to do next? What do i need to put in web.xml and how do I write my servlet so i can store file and return url of that object (if possible)

  • How to prevent Hibernate from nullifying relationship column during entity removal

    - by Grzegorz
    I have two entities, A and B. I need to easily retrieve entities A, joined with entities B on the condition of equal values of some column (some column from A equal to some column in B). Those columns are not primary or foreign keys, they contain same business data. I just need to have access from each instance of A to the collection of B's with the same value of this column. So I model it like this: class A { @OneToMany @JoinColumn(name="column_in_B", referencedColumnName="column_in_A") Collection<B> bs; This way, I can run queries like "select A join fetch a.bs b where b...." (Actually, the real relationship here is many-to-many. But when I use @ManyToMany, Hibernate forces me to use join table, which doesnt exist here. So I have to use @OneToMany as workaround). So far so good. The main problem is: whenever I delete an instance of A, hibernate calls "Update B set column_in_B = null", becuase it thinks the column_in_B is foreign key pointing at primary key in A (and because row in A is deleted, it tries to clean the foreign key in B). BUT the column_in_B IS NOT a foreign key, and can't be modified, because it causes data lost (and this column is NOT NULL anyway in my case, causing data integerity exception to be thrown). Plese help me with this. How to model such relationships with Hibernate? (I would call it "virtual relationships", or "secondary relationships" or so: as they are not based on foreign keys, they are just some shortcuts which allows for retrieving related objects and quering for them with HQL)

  • Why a "private static" is not seen in a method?

    - by Roman
    I have a class with the following declaration of the fields: public class Game { private static String outputFileName; .... } I set the value of the outputFileName in the main method of the class. I also have a write method in the class which use the outputFileName. I always call write after main sets value for outputFileName. But write still does not see the value of the outputFileName. It say that it's equal to null. Could anybody, pleas, tell me what I am doing wrong? ADDED As it is requested I post more code: In the main: String outputFileName = userName + "_" + year + "_" + month + "_" + day + "_" + hour + "_" + minute + "_" + second + "_" + millis + ".txt"; f=new File(outputFileName); if(!f.exists()){ try { f.createNewFile(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } System.out.println("IN THE MAIN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"); System.out.println("------>" + outputFileName + "<------"); This line outputs me the name of the file. Than in the write I have: public static void write(String output) { // Open a file for appending. System.out.println("==========>" + outputFileName + "<============"); ...... } And it outputs null.

  • MyMessage<T> throws an exception when calling XmlSerializer

    - by Arthis
    I am very new to nservicebus. I am using version 3.0.1, the last one up to date. And I wonder if my case is a normal limitation of NSB, I am not aware of. I have an asp.net MVC application, I am trying to setup and in my global.asax, I have the following : var configure = Configure.WithWeb() .DefaultBuilder() .ForMvc() .XmlSerializer(); But I have an error with the XmlSerializer when dealing with one of my object: [Serializable] public class MyMessage<T> : IMessage { public T myobject { get; set; } } I pass trough : XmlSerializer() instance.Initialize(types); this.InitType(type, moduleBuilder); this.InitType(info2.PropertyType, moduleBuilder); and then when dealing With T, string typeName = GetTypeName(t); typename is null and the following instruction : if (!nameToType.ContainsKey(typeName)) ends in error. null value not allowed. Is this some limitations to Nservicebus, or am I messing something up?

  • Gateway NE56R & mouse swipe gesture...how to disable?

    - by Anders
    Can anyone tell me how to shut off the swipe gesture mechanism on my computer? It's driving me crazy. I cannot use a single application without having my computer screen minimize every time I move my hand over the mouse following a mouse-click, pointer movement, etc. Having to maximize my spreadsheets, documents, and applications so much is undercutting my productivity. How some software engineer/inventor imagined that this mouse/gesture swipe gimmick would be helpful to computer users is inconceivable to me. It is a massive annoyance. I've found instructions online for disabling this obnoxious feature, but all the instructions involve messing with my registry, which I don't want to do. I will be SO GRATEFUL to any techie who can tell me how to disable this horrible mouse swipe mechanism without having to alter my registry! I'm using a Gateway NE56R Notebook, Windows 7 operating system, and an Inland USB Mouse (model no. 37535). Thank you in advance!

  • How to keep a trace of a record inside a nested repeater?

    - by Amokrane
    Hi, I have the following implementation: As you can see I have a repeater (listing the Machines) and a nested repeater (listing the WindowsServices inside each Machine). For each Windows Service I can perform an action using a button. However, to perform this action I need to know which Machine and which WindowsService are concerned. This is my code: protected void Page_Init(object sender, EventArgs e) { rptMachine.ItemDataBound += new RepeaterItemEventHandler(rptMachine_ItemDataBound); } protected void Page_Load(object sender, EventArgs e) { // bind the Machine repeater rptMachine.DataSource = _monitoringService.Machines; rptMachine.DataBind(); } protected void rptMachine_ItemDataBound(object sender, RepeaterItemEventArgs e) { if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) { Repeater nestedRepeater = (Repeater) e.Item.FindControl("rptWindowsService"); nestedRepeater.DataSource = ((IMachine) e.Item.DataItem).WindowsServices; nestedRepeater.DataBind(); Button btnActionInner = null; // bind the action button situated inside the nested repeater foreach(RepeaterItem ri in nestedRepeater.Items) { if((Button)ri.FindControl("btnAction") != null) { btnActionInner = (Button) ri.FindControl("btnAction"); btnActionInner.CommandName = "ActionState"; btnActionInner.CommandArgument = strWindowsService; } } } } protected void rptWindowsService_ItemCommand(object source, RepeaterCommandEventArgs e) { // do the specific action stop/run for the windows service if (e.CommandName == "ActionState") { if(((Button)(e.CommandSource)).Text.Equals("Stop")) { } else if(((Button)(e.CommandSource)).Text.Equals("Run")) { } } } } } So basically I need to know (inside rptWindowsService_ItemCommand) what is the pair that is concerned by the operation. What's the best way to do that? Don't hesitate to ask for more clarifications! Thanks

  • Planning management slots/sessions

    - by Glide
    I have a planning structure on two tables to store available slots by day, and sessions. A slot is defined by a range of time in the day. CREATE TABLE slot ( `id` int(11) NOT NULL AUTO_INCREMENT , `date` date , `start` time , `end` time ); Sessions can't overlap themselves and must be wrapped in a slot. CREATE TABLE session ( `id` int(11) NOT NULL AUTO_INCREMENT , `date` date , `start` time , `end` time ); I need to generate a list of available blocks of time of a certain duration, in order to create sessions. Example: INSERT INTO slot (date, start, end) VALUES ("2010-01-01", "10:00", "19:00") , ("2010-01-02", "10:00", "15:00") , ("2010-01-02", "16:00", "20:30") ; INSERT INTO slot (date, start, end) VALUES ("2010-01-01", "10:00", "19:00") , ("2010-01-02", "10:00", "15:00") , ("2010-01-02", "16:00", "20:30") ; 2010-01-01 <##><####> <- Sessions ------------------------------------ <- Slots 10 11 12 13 14 15 16 17 18 19 20 2010-01-02 <##########> <########> <- Sessions -------------------- ------------------ <- Slots 10 11 12 13 14 15 16 17 18 19 20 I need to know which spaces of 1 hour I can use: +------------+-------+-------+ | date | start | end | +------------+-------+-------+ | 2010-01-01 | 13:00 | 14:00 | | 2010-01-01 | 14:00 | 15:00 | | 2010-01-01 | 15:00 | 16:00 | | 2010-01-01 | 16:00 | 17:00 | | 2010-01-01 | 17:00 | 18:00 | | 2010-01-01 | 18:00 | 19:00 | | 2010-01-02 | 10:00 | 11:00 | | 2010-01-02 | 11:00 | 12:00 | | 2010-01-02 | 16:00 | 17:00 | +------------+-------+-------+

    Hi folks, I'm trying to wire up a simple ASP.NET MVC2 controller class to my own LoggingService. Code compiles fine, but I get the following runtime error :- {"StructureMap Exception Code: 202 No Default Instance defined for PluginFamily System.Type, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"} what the? mscorlib ????

  • Java resource closing

    - by Bob
    Hi, I'm writing an app that connect to a website and read one line from it. I do it like this: try{ URLConnection connection = new URL("www.example.com").openConnection(); BufferedReader rd = new BufferedReader(new InputStreamReader(connection.getInputStream())); String response = rd.readLine(); rd.close(); }catch (Exception e) { //exception handling } Is it good? I mean, I close the BufferedReader in the last line, but I do not close the InputStreamReader. Should I create a standalone InputStreamReader from the connection.getInputStream, and a BufferedReader from the standalone InputStreamReader, than close all the two readers? I think it will be better to place the closing methods in the finally block like this: InputStreamReader isr = null; BufferedReader br = null; try{ URLConnection connection = new URL("www.example.com").openConnection(); isr = new InputStreamReader(connection.getInputStream()); br = new BufferedReader(isr); String response = br.readLine(); }catch (Exception e) { //exception handling }finally{ br.close(); isr.close(); } But it is ugly, because the closing methods can throw exception, so I have to handle or throw it. Which solution is better? Or what would be the best solution?

  • Mocking Autofac's "Resolve" extension method with TypeMock

    - by Lockshopr
    I'm trying to mock an Autofac resolve, such as: using System; using Autofac; using TypeMock.ArrangeActAssert; class Program { static void Main(string[] args) { var inst = Isolate.Fake.Instance<IContainer>(); Isolate.Fake.StaticMethods(typeof(ResolutionExtensions), Members.ReturnNulls); Isolate.WhenCalled(() => inst.Resolve<IRubber>()).WillReturn(new BubbleGum()); Console.Out.WriteLine(inst.Resolve<IRubber>()); } } public interface IRubber {} public class BubbleGum : IRubber {} Coming from Moq, the syntax and exceptions from TypeMock confuse me a great deal. Having initially run this in a TestMethod, I kept getting an exception resembling "WhenCalled cannot be run without a complementing behavior". I tried defining behaviors for everyone and their mothers, but to no avail. Then I debug stepped through the test run, and saw that an actual exception was fired from Autofac: IRubber has not been registered. So it's obvious that the static Resolve function isn't being faked, and I can't get it to be faked, no matter how I go about hooking it up. Isolate.WhenCalled(() => ResolutionExtensions.Resolve<IRubber>(null)).WillReturn(new BubbleGum()); ... throws an exception from Autofac complaining that the IComponentContext cannot be null. Feeding it the presumably faked IContainer (or faking an IComponentContext instead) gets me back to the "IRubber not registered" error.

When i use jps i get the following response $ jps -l -m -v rmi://ec2-xxx-xxx-xxx-xxx.compute-1.amazonaws.com Error communicating with remote host: Connection refused to host: xxx.xxx.xxx.xxx; nested exception is: java.net.ConnectException: Connection timed out But i can ssh into the instance and use jps locally. Has anyone a pointer in which direction i can debug further?

  • How to loop video using NetStream in Data Generation Mode

    - by WesleyJohnson
    I'm using a NetStream in Data Generation Mode to play an embeded FLV using appendBytes. When the stream is finished playing, I'd like to loop the FLV file. I'm not sure how to achieve this. Here is what I have so far (this isn't a complete example): public function createBorderAnimation():void { // Load the skin image borderAnimation = Assets.BorderAnimation; // Convert the animation to a byte array borderAnimationBytes = new borderAnimation(); // Initialize the net connection border_nc = new NetConnection(); border_nc.connect( null ); // Initialize the net stream border_ns = new NetStream( border_nc ); border_ns.client = { onMetaData:function( obj:Object ):void{ trace(obj); } } border_ns.addEventListener( NetStatusEvent.NET_STATUS, border_netStatusHandler ); border_ns.play( null ); border_ns.appendBytes( borderAnimationBytes ); // Initialize the animation border_vd = new Video( 1024, 768 ); border_vd.attachNetStream( border_ns ); // Add the animation to the stage ui = new UIComponent(); ui.addChild( DisplayObject( border_vd ) ); grpBackground.addElement( ui ); } protected function border_netStatusHandler( event:NetStatusEvent ):void { if( event.info.code == "NetStream.Buffer.Flush" || event.info.code == "NetStream.Buffer.Empty" ) { border_ns.appendBytesAction( NetStreamAppendBytesAction.RESET_BEGIN ); border_ns.appendBytes( borderAnimationBytes ); border_ns.appendBytesAction( NetStreamAppendBytesAction.END_SEQUENCE ); } } This will loop the animation, but it starts chewing up memory like crazy. I've tried using NetStream.seek(0) and NetStream.appendBytesAction( NetStreamAppendBytesAction.RESET_SEEK ), but then I'm not sure what to do next. If you just try to call appendBytes again after that, it doesn't work, presumably because I'm appending the full byte array which has the FLV header and stuff? I'm not very familiar with how that all works. Any help is greatly appreciated.

  • select always returns -1 while trying to read from socket and stdin

    - by Aleyna
    Hello I have the following code implemented on C++(Linux) to check on my listening socket and stdin using select. select however keeps returning -1 no matter what I try to do! What's wrong with that code :s I will appreciate any help. Thanks highsock = m_sock; //listening socket memset((char *) &connectlist, 0, sizeof(connectlist)); memset((char *) &socks, 0, sizeof(socks)); int readsocks; struct timeval timeout; timeout.tv_sec = 60; timeout.tv_usec = 0; while (1) { updateSelectList(); //cout << "highest sock: " << highsock << endl; tempreadset = readset; readsocks = select(highsock+1, &tempreadset, NULL, NULL, &timeout); //cout << "# ready: " << readsocks << endl; if (readsocks < 0) { if (errno == EINTR) continue; cout << "select error" << endl; } if (readsocks > 0) { readFromSocks(); } } void readFromSocks() { if (FD_ISSET(STDIN, &readset)) { ... } else if (FD_ISSET(m_sock, &readset)) { ... } } void updateSelectList() { FD_ZERO(&readset); FD_SET(STDIN, &readset); FD_SET(m_sock, &readset); for (int i=0; i<MAXCONNECTIONS; i++) { if (connectlist[i] != 0) { FD_SET(connectlist[i], &readset); if (connectlist[i] > highsock) highsock = connectlist[i]; } } highsock = max(max(m_sock, STDIN), highsock); }

  • Where to put a textfile I want to use in eclipse?

    - by Jayomat
    hi there, I need to read a text file when I start my program. I'm using eclipse and started a new java project. In my project folder I got the "src" folder and the standard "JRE System Library"... I just don't know where to put the text file. I cannot use a "hard coded" path because the text file needs to be included with my app... I also tried to create a new folder like "Files" and use the pathe "Files/staedteliste.txt".. doesn't work too... I use the following code to read the file, but I get this error: Error:java.io.FileNotFoundException:staedteliste.txt(No such file or directory) import java.io.BufferedReader; import java.io.FileReader; import java.io.IOException; import java.util.ArrayList; public class Test { ArrayList<String[]> values; public static void main(String[] args) { // TODO Auto-generated method stub loadList(); } public static void loadList() { BufferedReader reader; String zeile = null; try { reader = new BufferedReader(new FileReader("staedteliste.txt")); zeile = reader.readLine(); ArrayList<String[]> values = new ArrayList<String[]>(); while (zeile != null) { values.add(zeile.split(";")); zeile = reader.readLine(); } System.out.println(values.size()); System.out.println(zeile); } catch (IOException e) { System.err.println("Error :"+e); } } } thx for help!
