  • JQuery Simplemodal and Tabs Help Needed

    - by Dave R
    Hi, I've got an asp.net page containing a Textbox with an Autocomplete extender on it. It's setup so the user can type a short reference code into the textbox and then choose from the list of matching codes returned by the autocomplete. On the "select", I then call the server using JQuery. I'm currently using $.get here.... The callback function from $.get checks for "success" and then displays a simple-modal dialog containing info about the item they've just selected. if (sStatus == "success") { $.modal(sText, { overlayClose: true, appendTo:'form', onShow: function(dialog) { $("#ccTargets_tabContainer").tabs(); }, onClose: function(dialog) { $("#<%=TextBox1.ClientID%>").val(""); $.modal.close(); } }); $.ready(); } One of the bits of info being loaded here is a JQuery TABS setup, so the onShow function of the simplemodal is used to initiate the tabs which are within the simplemodal. Now to the crux of my problem. If I do multiple consecutive "autocompletes" on the same page it all works fine Unless I have selected a different tab on the tabs in the simplemodal ....If I select a different tab, close the simplemodal and then do another autocomplete I get a JQuery error which seems to relate to a selector doing something with the "old" selected tab that was on the "closed" modal. I'm clearly missing some sort of cleardown / initialisation somewhere, but can't find what it is. Help? I've tried "tabs.destroy" before the modal call in the code above and I've tried a $.ready() call as indicated too.... UPDATE: Is it something to do with JQuery Tabs appending my addressbar URL with the selected tab's ID?

  • WCF configuration and ISA Proxies

    - by Morten Louw Nielsen
    Hi, I have a setup with a .NET WCF Service hosted on IIS. The client apps are connecting to the service through a set of ISA proxy's. I don't know how many and don't know about their configuration etc. In the client apps I open a client to the service and make several calls via the same client. It works great in my office, but when I deploy at the customer (using the ISAs), after some calls, the connection breaks. In a successfull case, the client will maximum live a few seconds, but is that too much? I think there might be several proxyes. Maybe it's using load ballancing. pseudo code is something like this: WcfClient myClient = new WcfClient(); foreach (WorkItem Item in WorkItemsStack) myClient.ProcessItem(Item); myClient.Close(); I am thinking whether I have to do something like this foreach (WorkItem Item in WorkItemsStack) { WcfClient myClient = new WcfClient(); myClient.ProcessItem(Item); myClient.Close(); } Any one with experience with this field? Kind Regards, Morten, Denmark

  • Problems with QDialog in Qt

    - by Martin
    I'm using Qt for Symbian. I have some problems with a QDialog that I open from a QMenu. The QDialog shows up fine and in the QDialog I have a QDialogButtonBox with a button to Close the QDialog. BUT if I close the QDialog and then open it from the QMenu again, it will show up but the button from the QDialogButtonBox will not show up. Instead the buttons from the QMainWindow will show but they are grayed out. How can I get the QDialog buttons to show every time? Maybe I have some problems with setting focus on the QDialog? I really can't see what I'm doing wrong here. It's not much code that I use, you can try it yourself. This is my code: In QMainWindow I use the following to create the menu: QAction *menuButton = new QAction("Menu", this); menuButton->setSoftKeyRole(QAction::PositiveSoftKey); QMenu *menu = new QMenu(this); menuButton->setMenu(menu); QAction *popup = new QAction("Show popup",this); connect(popup, SIGNAL(triggered()), this, SLOT(showPopup())); menu->addAction(popup); addAction(menuButton); This shows the QDialog: void MyMainWindow::showPopup(){ TestDialog *test = new TestDialog(this); test->setAttribute(Qt::WA_DeleteOnClose); test->show(); } This is the TestDialog: TestDialog::TestDialog(QWidget *parent) : QDialog(parent) { ui.setupUi(this); QDesktopWidget* desktopWidget = QApplication::desktop(); QRect rect = desktopWidget->availableGeometry(); this->setFixedWidth(rect.width()); }

  • Winform User Settings - Allow multiple choice values at Runtime

    - by Refracted Paladin
    I created a simple User Settings Dialog by binding the Property.Settings to a PropertyGrid. This works like a charm but now I would like to allow only certain choices for some values. I have noticed that some Types will give a dropdown of possible choices. This is what I am shooting for but for, say, Strings. Example, one of the Settings is UserTheme which is a String. Black, Blue, Silver. The program reads that string from the Settings File and sets the Theme on Startup. I can type in a correct theme and it works but if I type in Pink it will not as there is not a pink option. This is my VERY simple UserSettingsForm code. #region FIELDS internal Settings userSettings; #endregion #region EVENTS private void frmEditUserControl_Load(object sender, EventArgs e) { userSettings = Settings.Default; this.propertyGrid1.SelectedObject = userSettings; this.propertyGrid1.PropertySort = PropertySort.Alphabetical; } private void btnSave_Click(object sender, EventArgs e) { userSettings.Save(); //this.DialogResult = DialogResult.OK; this.Close(); } private void btnCancel_Click(object sender, EventArgs e) { userSettings.Reload(); this.Close(); } #endregion

  • php: fopen() of an URL breaks for domain names, not for numerical addresses

    - by b0fh
    After hours of trying to debug a third-party application having trouble with fopen(), i finally discovered that php -r 'echo(file_get_contents("http://www.google.com/robots.txt"));' fails, but php -r 'echo(file_get_contents("http://173.194.32.81/robots.txt"));' Succeeds. Note that as the webserver user, I can ping www.google.com and it resolves just fine. I straced both executions of PHP, and they diverge like this: For the numerical v4 URL: socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 3 fcntl(3, F_GETFL) = 0x2 (flags O_RDWR) fcntl(3, F_SETFL, O_RDWR|O_NONBLOCK) = 0 connect(3, {sa_family=AF_INET, sin_port=htons(80), sin_addr=inet_addr("173.194 poll([{fd=3, events=POLLOUT}], 1, 0) = 0 (Timeout) ...[bunch of poll/select/recvfrom]... close(3) = 0 For the domain name: socket(PF_INET6, SOCK_DGRAM, IPPROTO_IP) = 3 close(3) = 0 PHP didn't even try to do anything with that socket, it seems. Or even resolve the domain, for that matter. WTF ? Recompiling PHP with or without ipv6 support did not seem to matter. Disabling ipv6 on this system is not desirable. Gentoo Linux, PHP 5.3.14, currently giving a try to PHP 5.4 and see if it helps. Anyone has an idea ? EDIT: php -r 'echo gethostbyname("www.google.com");' Works and yield an ipv4, while php -r 'echo(file_get_contents("http://[2a00:1450:4007:803::1011]/"));' Seems to return a blank result. EDIT 2: I didn't even notice the first time, that the v6 socket opened when the name is used is a SOCK_DGRAM.

  • Coherent access to mainframe files from Win32 application and IBM RDZ/Eclipse?

    - by Ira Baxter
    I have a suite of tools for processing IBM COBOL source code; these tools are built as Win32 applications and talk to Windows (including network) files using traditional Windows file system calls (open, close, read, write) and work just fine, thank you. I'd like to integrate these with Eclipse; we understand how to get Eclipse to do UI for us we think. The problem is that Eclipse/RDZ users access mainframe files through some IBM magic. In How does RDZ access mainframe files I tried to understand how Eclipse accessed files on a mainframe. Apparantly Eclipse/RDZ has a secret filesystem access backdoor not available to normal mortals. At issue is how our tools, reading some Windows-accessible file (local disk file, NFS to mainframe, ...) can associate such files with the files that Eclipse can access or is using? Ideally we'd like UI-integrated versions of our tools take an Eclipse file-name string for a mainframe file, pass it to our Windows application to process, have the Windows application open/read/process the file, and return results associated with that file to the Eclipse UI. Is there a canonical file name path that would be used with mainframe NFS that would be equivalent to the name or access object the Eclipse RDZ used to access the same file? Are all operations doable internally by Eclipse, doable by the mainframe NFS [for instance, can NFS read/update an element in a partitioned data set? Can Eclipse RDZ? Does it matter?] Is the mainframe file access available to custom Java code running under Eclipse RDZ (e.g., equivalents of open/close/read/write based on filename/path/something?) If so, can somebody steer me towards documentation describing the access methods? Anybody else already solve this problem or have a good suggestion?

  • Call Multiple Stored Procedures with the Zend Framework

    - by Brian Fisher
    I'm using Zend Framework 1.7.2, MySQL and the MySQLi PDO adapter. I would like to call multiple stored procedures during a given action. I've found that on Windows there is a problem calling multiple stored procedures. If you try it you get the following error message: SQLSTATE[HY000]: General error: 2014 Cannot execute queries while other unbuffered queries are active. Consider using PDOStatement::fetchAll(). Alternatively, if your code is only ever going to run against mysql, you may enable query buffering by setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute. I found that to work around this issue I could just close the connection to the database after each call to a stored procedure: if (strtoupper(substr(PHP_OS, 0, 3)) === 'WIN') { //If on windows close the connection $db->closeConnection(); } This has worked well for me, however, now I want to call multiple stored procedures wrapped in a transaction. Of course, closing the connection isn't an option in this situation, since it causes a rollback of the open transaction. Any ideas, how to fix this problem and/or work around the issue.

  • GZIP Java vs .NET

    - by Jim Jones
    Using the following Java code to compress/decompress bytes[] to/from GZIP. First text bytes to gzip bytes: public static byte[] fromByteToGByte(byte[] bytes) { ByteArrayOutputStream baos = null; try { ByteArrayInputStream bais = new ByteArrayInputStream(bytes); baos = new ByteArrayOutputStream(); GZIPOutputStream gzos = new GZIPOutputStream(baos); byte[] buffer = new byte[1024]; int len; while((len = bais.read(buffer)) >= 0) { gzos.write(buffer, 0, len); } gzos.close(); baos.close(); } catch (IOException e) { e.printStackTrace(); } return(baos.toByteArray()); } Then the method that goes the other way compressed bytes to uncompressed bytes: public static byte[] fromGByteToByte(byte[] gbytes) { ByteArrayOutputStream baos = null; ByteArrayInputStream bais = new ByteArrayInputStream(gbytes); try { baos = new ByteArrayOutputStream(); GZIPInputStream gzis = new GZIPInputStream(bais); byte[] bytes = new byte[1024]; int len; while((len = gzis.read(bytes)) > 0) { baos.write(bytes, 0, len); } } catch (IOException e) { e.printStackTrace(); } return(baos.toByteArray()); } Think there is any effect since I'm not writing out to a gzip file? Also I noticed that in the standard C# function that BitConverter reads the first four bytes and then the MemoryStream Write function is called with a start point of 4 and a length of input buffer length - 4. So is that effect the validity of the header? Jim

  • javascript addEventListener onStateChange not working in IE

    - by user347456
    Hi, I have two colorbox popup boxes which show a youtube video in each. When they're finished playing, I'm trying to have them automatically close the colorbox window. This code below works perfect in firefox, but in IE I can't get addEventListener to work. I've tried attachEvent with no success. Can anybody offer any suggestions as to how to solve this? It seems simple but I'm exhausted trying to find a solution. By the way, this is my first time as stackoverflow and it's very impressive. var params = { allowScriptAccess: "always" }; var atts = { id: "ytplayer1" }; swfobject.embedSWF("http://www.youtube.com/v/VIDEO1&rel=0&hl=en_US&fs=0&autoplay=1&enablejsapi=1&playerapiid=ytvideo1", "popupVideoContainer1", "640", "385", "8", null, null, params, atts); var params2 = { allowScriptAccess: "always" }; var atts2 = { id: "ytplayer2" }; swfobject.embedSWF("http://www.youtube.com/v/VIDEO2&rel=0&hl=en_US&fs=0&autoplay=1&enablejsapi=1&playerapiid=ytvideo2", "popupVideoContainer2", "640", "385", "8", null, null, params2, atts2); function onYouTubePlayerReady(playerId) { if(playerId == 'ytvideo1'){ var ytplayer = document.getElementById('ytplayer1'); ytplayer.addEventListener("onStateChange", "onytplayerStateChange", false); } else if(playerId == 'ytvideo2'){ var ytplayer = document.getElementById("ytplayer2"); //ytplayer.addEventListener("onStateChange", "onytplayerStateChange", false); if (ytplayer.addEventListener) { ytplayer.addEventListener("onStateChange", "onytplayerStateChange", false); } else if (ytplayer.attachEvent) { ytplayer.attachEvent("onStateChange", onytplayerStateChange); } } } function onytplayerStateChange(newState) { if(newState == 0){ $.fn.colorbox.close(); } }

  • MS-Access: What could cause one form with a join query to load right and another not?

    - by Daniel Straight
    Form1 Form1 is bound to Table1. Table1 has an ID field. Form2 Form2 is bound to Table2 joined to Table1 on Table2.Table1_ID=Table1.ID Here is the SQL (generated by Access): SELECT Table2.*, Table1.[FirstFieldINeed], Table1.[SecondFieldINeed], Table1.[ThirdFieldINeed] FROM Table1 INNER JOIN Table2 ON Table1.ID = Table2.[Table1_ID]; Form2 is opened with this code in Form1: DoCmd.RunCommand acCmdSaveRecord DoCmd.OpenForm "Form2", , , , acFormAdd, , Me.[ID] DoCmd.Close acForm, "Form1", acSaveYes And when loaded runs: Me.[Table1_ID] = Me.OpenArgs When Form2 is loaded, fields bound to columns from Table1 show up correctly. Form3 Form3 is bound to Table3 joined to Table2 on Table3.Table2_ID=Table2.ID Here is the SQL (generated by Access): SELECT Table3.*, Table2.[FirstFieldINeed], Table2.[SecondFieldINeed] FROM Table2 INNER JOIN Table3 ON Table2.ID = Table3.[Table2_ID]; Form3 is opened with this code in Form2: DoCmd.RunCommand acCmdSaveRecord DoCmd.OpenForm "Form3", , , , acFormAdd, , Me.[ID] DoCmd.Close acForm, "Form2", acSaveYes And when loaded runs: Me.[Table2_ID] = Me.OpenArgs When Form3 is loaded, fields bound to columns from Table2 do not show up correctly. WHY? UPDATES I tried making the join query into a separate query and using that as my record source, but it made no difference at all. If I go to the query for Form3 and view it in datasheet view, I can see that the information that should be pulled into the form is there. It just isn't showing up on the form.

  • How should bug tracking and help tickets integrate?

    - by Max Schmeling
    I have a little experience with bug tracking systems such as FogBugz where help tickets are issues are (or can be) bugs, and I have some experience using a bug tracking system internally completely separate from a help center system. My question is, in a company with an existing (home-grown) help center system where replacing it is not an option, how should a bug tracking system (probably Mantis) be integrated into the process? Right now help tickets get put in for issues, questions, etc and they get assigned to the appropriate person (PC Tech, Help Desk staff, or if it's an application issue they can't solve in the help desk it gets assigned to a developer). A user can put a request for small modifications or fixes to an application in a help ticket and the developer it gets assigned to will make the change at some point, apply their time to that ticket, and then close the ticket when it goes to production. We don't currently have a bug tracking system, so I'm looking into the best way to integrate one. Should we just take the help tickets and put it into the bug tracking system if it's a bug (or issue or feature request) and then close the ticket if it's not an emergency fix? We probably don't want to expose the bug tracking system to anyone else as they wouldn't know what to put in the help center system and what to put in the bug tracker... right? Any thoughts? Suggestions? Tips? Advice? To-dos? Not to-dos? etc...

  • How can I terminate a system command with alarm in Perl?

    - by rockyurock
    I am running the below code snippet on Windows. The server starts listening continuously after reading from client. I want to terminate this command after a time period. If I use alarm() function call within main.pl, then it terminates the whole Perl program (here main.pl), so I called this system command by placing it in a separate Perl file and calling this Perl file (alarm.pl) in the original Perl File using the system command. But in this way I was unable to take the output of this system() call neither in the original Perl File nor in called one Perl File. Could anybody please let me know the way to terminate a system() call or take the output in that way I used above? main.pl my @output = system("alarm.pl"); print"one iperf completed\n"; open FILE, ">display.txt" or die $!; print FILE @output_1; close FILE; alarm.pl alarm 30; my @output_1 = readpipe("adb shell cd /data/app; ./iperf -u -s -p 5001"); open FILE, ">display.txt" or die $!; print FILE @output_1; close FILE; In both ways display.txt is always empty.

  • Search for string allowing for one mismatches in any location of the string, Python

    - by Vincent
    I am working with DNA sequences of length 25 (see examples below). I have a list of 230,000 and need to look for each sequence in the entire genome (toxoplasma gondii parasite) I am not sure how large the genome is but much more that 230,000 sequences. I need to look for each of my sequences of 25 characters example(AGCCTCCCATGATTGAACAGATCAT). The genome is formatted as a continuous string ie (CATGGGAGGCTTGCGGAGCCTGAGGGCGGAGCCTGAGGTGGGAGGCTTGCGGAGTGCGGAGCCTGAGCCTGAGGGCGGAGCCTGAGGTGGGAGGCTT.........) I don't care where or how many times it is found, just yes or no. This is simple I think, str.find(AGCCTCCCATGATTGAACAGATCAT) But I also what to find a close match defined as wrong(mismatched) at any location but only 1 location and record the location in the sequnce. I am not sure how do do this. The only thing I can think of is using a wildcard and performing the search with a wildcard in each position. ie search 25 times. For example AGCCTCCCATGATTGAACAGATCAT AGCCTCCCATGATAGAACAGATCAT close match with a miss-match at position 13 Speed is not a big issue I am only doing it 3 times. i hope but it would be nice it was fast. The are programs that do this find matches and partial matches but I am looking for a type of partial match that is not available with these applications. Here is a similar post for pearl but they are only comparing sequnces not searching a continuous string Related post

  • How can I improve my real-time behavior in multi-threaded app using pthreads and condition variables

    - by WilliamKF
    I have a multi-threaded application that is using pthreads. I have a mutex() lock and condition variables(). There are two threads, one thread is producing data for the second thread, a worker, which is trying to process the produced data in a real time fashion such that one chuck is processed as close to the elapsing of a fixed time period as possible. This works pretty well, however, occasionally when the producer thread releases the condition upon which the worker is waiting, a delay of up to almost a whole second is seen before the worker thread gets control and executes again. I know this because right before the producer releases the condition upon which the worker is waiting, it does a chuck of processing for the worker if it is time to process another chuck, then immediately upon receiving the condition in the worker thread, it also does a chuck of processing if it is time to process another chuck. In this later case, I am seeing that I am late processing the chuck many times. I'd like to eliminate this lost efficiency and do what I can to keep the chucks ticking away as close to possible to the desired frequency. Is there anything I can do to reduce the delay between the release condition from the producer and the detection that that condition is released such that the worker resumes processing? For example, would it help for the producer to call something to force itself to be context switched out? Bottom line is the worker has to wait each time it asks the producer to create work for itself so that the producer can muck with the worker's data structures before telling the worker it is ready to run in parallel again. This period of exclusive access by the producer is meant to be short, but during this period, I am also checking for real-time work to be done by the producer on behalf of the worker while the producer has exclusive access. Somehow my hand off back to running in parallel again results in significant delay occasionally that I would like to avoid. Please suggest how this might be best accomplished.

  • destroy cfwindow in javascript 'is not a function'

    - by Ryan French
    Hi All, Having an issue here that I have tried everything I can think of but cant get it to work. I have a page with a link that creates a cfwindow like so function create_window(ID){ var config = new Object(); config.modal=true; config.center=true; config.height=775; config.width=700; config.resizable=false; config.closable=false; config.draggable=false; config.refreshonshow=true; ColdFusion.Window.create('newWindow','Window Title', '/source/url'+ID, config) The window is created and the URL has the ID parsed to it that is used for displaying the correct item in the window. This all works fine. The problem is when I try and close the window and open a new window with a different item being displayed, the URL is not changed. I realise that this is because the window is being hidden, and not destroyed, and therefore it is the same window being opened. So I have created an onHide event handler to destroy the window like so. function showItemDetails(){ var ID=document.getElementById("sList").value create_window(ID); ColdFusion.Window.onHide('newWindow', refreshList); } function refreshList(){ ColdFusion.bindHandlerCache['sList'].call(); ColdFusion.Window.destroy('newWindow',true); } Now when I close the window Firebug is returning the error "ColdFusion.Window.destroy is not a function" (In IE the error is "Object doesn't support this property or method"). I have made sure we are running the latest version of ColdFusion 8.01 on the server (as I know that .destroy wasnt added until 8.01) and have applied the latest hotfixes to the server as well. Any ideas?

  • How does Subsonic handle connections?

    - by Quintin Par
    In Nhibernate you start a session by creating it during a BeginRequest and close at EndRequest public class Global: System.Web.HttpApplication { public static ISessionFactory SessionFactory = CreateSessionFactory(); protected static ISessionFactory CreateSessionFactory() { return new Configuration() .Configure(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "hibernate.cfg.xml")) .BuildSessionFactory(); } public static ISession CurrentSession { get{ return (ISession)HttpContext.Current.Items["current.session"]; } set { HttpContext.Current.Items["current.session"] = value; } } protected void Global() { BeginRequest += delegate { CurrentSession = SessionFactory.OpenSession(); }; EndRequest += delegate { if(CurrentSession != null) CurrentSession.Dispose(); }; } } What’s the equivalent in Subsonic? The way I understand, Nhibernate will close all the connections at endrequest. Reason: While trouble shooting some legacy code in a Subsonic project I get a lot of MySQL timeouts,suggesting that the code is not closing the connections MySql.Data.MySqlClient.MySqlException: error connecting: Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.

  • Paypal sandbox account in dotnet: "IPN Response invalid"

    - by Sam
    I am integrating Paypal with my website. I use a sandbox account, one buyer account and one seller account. I downloaded the code below from Paypal: string strSandbox = "https://www.sandbox.paypal.com/cgi-bin/webscr"; HttpWebRequest req = (HttpWebRequest)WebRequest.Create(strSandbox); //Set values for the request back req.Method = "POST"; req.ContentType = "application/x-www-form-urlencoded"; byte[] param = Request.BinaryRead(HttpContext.Current.Request.ContentLength); string strRequest = Encoding.ASCII.GetString(param); strRequest += "&cmd=_notify-validate"; req.ContentLength = strRequest.Length; //for proxy //WebProxy proxy = new WebProxy(new Uri("http://url:port#")); //req.Proxy = proxy; //Send the request to PayPal and get the response StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII); streamOut.Write(strRequest); streamOut.Close(); StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream()); string strResponse = streamIn.ReadToEnd(); streamIn.Close(); if (strResponse == "VERIFIED") { //check the payment_status is Completed //check that txn_id has not been previously processed //check that receiver_email is your Primary PayPal email //check that payment_amount/payment_currency are correct //process payment } else if (strResponse == "INVALID") { //log for manual investigation } else { //log response/ipn data for manual investigation } When I add this snippet in my pageload event of my success page, I show the IPN response as INVALID, but amount is paid successfully. Why is this? Paypal's docs are not clear.

  • record output sound in python

    - by aaronstacy
    i want to programatically record sound coming out of my laptop in python. i found PyAudio and came up with the following program that accomplishes the task: import pyaudio, wave, sys chunk = 1024 FORMAT = pyaudio.paInt16 CHANNELS = 1 RATE = 44100 RECORD_SECONDS = 5 WAVE_OUTPUT_FILENAME = sys.argv[1] p = pyaudio.PyAudio() channel_map = (0, 1) stream_info = pyaudio.PaMacCoreStreamInfo( flags = pyaudio.PaMacCoreStreamInfo.paMacCorePlayNice, channel_map = channel_map) stream = p.open(format = FORMAT, rate = RATE, input = True, input_host_api_specific_stream_info = stream_info, channels = CHANNELS) all = [] for i in range(0, RATE / chunk * RECORD_SECONDS): data = stream.read(chunk) all.append(data) stream.close() p.terminate() data = ''.join(all) wf = wave.open(WAVE_OUTPUT_FILENAME, 'wb') wf.setnchannels(CHANNELS) wf.setsampwidth(p.get_sample_size(FORMAT)) wf.setframerate(RATE) wf.writeframes(data) wf.close() the problem is i have to connect the headphone jack to the microphone jack. i tried replacing these lines: input = True, input_host_api_specific_stream_info = stream_info, with these: output = True, output_host_api_specific_stream_info = stream_info, but then i get this error: Traceback (most recent call last): File "./test.py", line 25, in data = stream.read(chunk) File "/Library/Python/2.5/site-packages/pyaudio.py", line 562, in read paCanNotReadFromAnOutputOnlyStream) IOError: [Errno Not input stream] -9975 is there a way to instantiate the PyAudio stream so that it inputs from the computer's output and i don't have to connect the headphone jack to the microphone? is there a better way to go about this? i'd prefer to stick w/ a python app and avoid cocoa.

  • How can I control the action of onbeforeunload in IE?

    - by SpawnCxy
    Hi all I've got a problem about onbeforeunload recently that I need to pop up a voting page if the user try closes their IE browser.And I did it by using <body onbeforeunload="makevote()"> And the main structure of makevote() in javascript as follows: function makevote() { comet.distruct(); if(csid != null && isvote == null) { window.event.returnValue = false window.event.returnValue='press “cancel” to vote please!' showComDiv(popvote,"popiframe",400,120,'your vote here','dovote()'); } } For last three months this voting function performed so ugly that I got only less than 8,000 votes from more than 4,50,000 vistors.I think the problem is, when the users try to close their browsers,the onbeforeunload property pops up a comfirm box which covered my voting box while most users click the OK button,which means close comfirming is done,as a habit.So my question is how can I control the comfirming box made by onbeforeunload myself? So far I can only define the message it shows.For example if I click the "OK" ,I'll go to the voting box instead of closing my IE.And if there's any other better way to do this?Help would be greatly appreciated! Regards

  • Isolated storage misunderstand

    - by Costa
    Hi this is a discussion between me and me to understand isolated storage issue. can you help me to convince me about isolated storage!! This is a code written in windows form app (reader) that read the isolated storage of another win form app (writer) which is signed. where is the security if the reader can read the writer's file, I thought only signed code can access the file! If all .Net applications born equal and have all permissions to access Isolated storage, where is the security then? If I can install and run Exe from isolated storage, why I don't install a virus and run it, I am trusted to access this area. but the virus or what ever will not be trusted to access the rest of file system, it only can access the memory, and this is dangerous enough. I cannot see any difference between using app data folder to save the state and using isolated storage except a long nasty path!! I want to try give low trust to Reader code and retest, but they said "Isolated storage is actually created for giving low trusted application the right to save its state". Reader code: private void button1_Click(object sender, EventArgs e) { String path = @"C:\Documents and Settings\All Users\Application Data\IsolatedStorage\efv5cmbz.ewt\2ehuny0c.qvv\StrongName.5v3airc2lkv0onfrhsm2h3uiio35oarw\AssemFiles\toto12\ABC.txt"; StreamReader reader = new StreamReader(path); var test = reader.ReadLine(); reader.Close(); } Writer: private void button1_Click(object sender, EventArgs e) { IsolatedStorageFile isolatedFile = IsolatedStorageFile.GetMachineStoreForAssembly(); isolatedFile.CreateDirectory("toto12"); IsolatedStorageFileStream isolatedStorage = new IsolatedStorageFileStream(@"toto12\ABC.txt", System.IO.FileMode.Create, isolatedFile); StreamWriter writer = new StreamWriter(isolatedStorage); writer.WriteLine("Ana 2akol we ashrab kai a3eesh wa akbora"); writer.Close(); writer.Dispose(); }

  • ibatis problem using <isNull> whilst iterating over a List

    - by onoma
    Hi, I'm new to iBatis and I'm struggling with the and elements. I want to iterate over a List of Book instances (say) that are passed in as a HashMap: MyParameters. The list will be called listOfBooks. The clause of the overall SQL statement will therefore look like this: <iterate prepend="AND" property="MyParameters.listOfBooks" conjunction="AND" open="(" close=")"> ... </iterate> I also need to produce different SQL within the iterate elements depending on whether a property of each Book instance in the 'listOfBooks' List is null, or not. So, I need a statement something like this: <iterate prepend="AND" property="MyParameters.listOfBooks" conjunction="AND" open="(" close=")"> <isNull property="MyParameter.listOfBooks.title"> <!-- SQL clause #1 here --> </isNull> <isNotNull property="MyParameter.listOfBooks.title"> <!-- SQL clause #2 here --> </isNotNull> When I do this I get an error message stating that there is no "READABLE" property named 'title' in my Book class. However, each Book instance does contain a title property, so I'm confused! I can only assuem that I have managled the syntax in trying to pinpoint the title of particular Book instance in listOfBooks. I'm struggling to find the correct technique for trying to achieve this. If anyone can advise a way forward I'd be grateful. Thanks
