  • Vaadin: Downloaded file has whole path as file name

    - by javydreamercsw
    I have a download action implemented on my Vaadin application but for some reason the downloaded file has the original file's full path as the file name. Any idea? You can see the code on this post. Edit: Here's the important part of the code: package com.bluecubs.xinco.core.server.vaadin; import com.bluecubs.xinco.core.server.XincoConfigSingletonServer; import com.vaadin.Application; import com.vaadin.terminal.DownloadStream; import com.vaadin.terminal.FileResource; import java.io.*; import java.net.URLEncoder; import java.util.UUID; import java.util.logging.Level; import java.util.logging.Logger; import java.util.zip.CRC32; import java.util.zip.CheckedInputStream; /** * * @author Javier A. Ortiz Bultrón<[email protected]> */ public class FileDownloadResource extends FileResource { private final String fileName; private File download; private File newFile; public FileDownloadResource(File sourceFile, String fileName, Application application) { super(sourceFile, application); this.fileName = fileName; } protected void cleanup() { if (newFile != null && newFile.exists()) { newFile.delete(); } if (download != null && download.exists() && download.listFiles().length == 0) { download.delete(); } } @Override public DownloadStream getStream() { try { //Copy file to directory for downloading InputStream in = new CheckedInputStream(new FileInputStream(getSourceFile()), new CRC32()); download = new File(XincoConfigSingletonServer.getInstance().FileRepositoryPath + System.getProperty("file.separator") + UUID.randomUUID().toString()); newFile = new File(download.getAbsolutePath() + System.getProperty("file.separator") + fileName); download.mkdirs(); OutputStream out = new FileOutputStream(newFile); newFile.deleteOnExit(); download.deleteOnExit(); byte[] buf = new byte[1024]; int len; while ((len = in.read(buf)) > 0) { out.write(buf, 0, len); } in.close(); out.close(); final DownloadStream ds = new DownloadStream( new FileInputStream(newFile), getMIMEType(), fileName); ds.setParameter("Content-Disposition", "attachment; filename=" + URLEncoder.encode(fileName, "utf-8")); ds.setCacheTime(getCacheTime()); return ds; } catch (final FileNotFoundException ex) { Logger.getLogger(FileDownloadResource.class.getName()).log(Level.SEVERE, null, ex); return null; } catch (IOException ex) { Logger.getLogger(FileDownloadResource.class.getName()).log(Level.SEVERE, null, ex); return null; } } } I already debugged and verified that fileName only contains the file's name not the whole path.

  • Modern monitor technologies - need to find a new monitor

    - by Michal Minicki
    I'm preparing to change my old LCD monitor for a new one. I have an old NEC 20WGX2 Pro based on an IPS panel. I'm looking for a screen that gives good color output but is very good at gaming at the same time (since it is its primary service). I tend to switch monitors between my different computers at home so it has to be multi purpose, hence IPS technology before. Now, where can I read on newest monitor technologies so I can make an informed decision? I need to find a best fit for myself and I have a very outdated knowledge at the moment. So any hints are greatly appreciated, be it info on technologies, web sources, links to other questions, etc.

  • Nagios Check_hpjd giving me problems!

    - by Mister IT Guru
    When I run the following [root@host plugins]# ./check_hpjd -H printer1.mydomain.com : Timeout from host printer1.mydomain.com I have Net-snmp installed on my system, I noted that i didn't have net-snmp-utils installed, and then I was able to run [root@host plugins]# snmpwalk -Os -c public -v 1 printer1.mydomain.com system sysDescr.0 = STRING: HP ETHERNET MULTI-ENVIRONMENT sysObjectID.0 = OID: enterprises.11.2.3.9.1 sysUpTimeInstance = Timeticks: (325408663) 37 days, 15:54:46.63 sysContact.0 = STRING: sysName.0 = STRING: printer1 sysLocation.0 = STRING: sysServices.0 = INTEGER: 72 So I know that the printer is working as expected, (as far as SNMP is concerned). But when I run [root@host plugins]# ./check_hpjd -H printer1.mydomain.com -C public Error in packet () I get this error - From what I've tried so far, I know my host can communicate via SNMP, I know the printer responds via SNMP, so I guess I'm left to look at the plug-in, which I will be checking up on. I'm new to SNMP, I am investigating this with my good friend Google search, but I am on a learning curve here, so please forgive my questions if they sound stupid,

  • How to add some complex structure in multiple places in an XML file

    - by Guillaume
    I have an XML file which has many section like the one below: <Operations> <Action [some attributes ...]> [some complex content ...] </Action> <Action [some attributes ...]> [some complex content ...] </Action> </Operations> I have to add an <Action/> to every <Operations/>. It seems that an XSLT should be a good solution to this problem: <xsl:template match="Operations/Action[last()]"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> <Action>[some complex content ...]</Action> </xsl:template> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> My problem is that the content of my <Action/> contains some xPath expressions. For example: <Action code="p_histo01"> <customScript languageCode="gel"> <gel:script xmlns:core="jelly:core" xmlns:gel="jelly:com.niku.union.gel.GELTagLibrary" xmlns:soap="jelly:com.niku.union.gel.SOAPTagLibrary" xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:sql="jelly:sql" xmlns:x="jelly:xml" xmlns:xog="http://www.niku.com/xog" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <sql:param value="${gel_stepInstanceId}"/> </gel:script> </customScript> </Action> The ${gel_stepInstanceId} is interpreted by my XSLT but I would like it to be copied as-is. Is that possible? How?

  • Example of use of unregistered, dynamically created gen_server's?

    - by me2
    Tutorials are abound for working with gen_servers that are named in an OTP application. However, I've been unable to find a good example of dynamically spawning servers that are not registered (not named). Can someone point to a good, simple example? Not ejabberd, for example, where there is a lot to confuse the core idea I'm trying to get at. Thanks.

  • COMException Problem

    - by Jack Harvin
    Wondering if anyone could help with my problem. Below is the code, and after the code an explination of where the exception is thrown. using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.Web; using WatiN.Core; using System.Threading; using System.IO; namespace WindowsFormsApplication1 { public partial class Form1 : System.Windows.Forms.Form { public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { } private void button1_Click(object sender, EventArgs e) { Thread t = new Thread(createApplications); Settings.AutoStartDialogWatcher = false; t.SetApartmentState(System.Threading.ApartmentState.STA); t.Start(); } private void createApplications() { createApp("username", "password", "Test App", "This is just a test description", "http:/mysite.com"); } private void createApp(String username, String password, String appName, String description, String appUrl) { var currentBrowser = new IE("http://mysite.com/login/php"); currentBrowser.TextField(Find.ById("username")).TypeText(username); currentBrowser.TextField(Find.ById("password")).TypeText(password); currentBrowser.Button(Find.ById("submit")).Click(); currentBrowser.GoTo("http://mysite.com/createmusicapp.php"); currentBrowser.TextField(Find.ById("application_name")).TypeText(appName); currentBrowser.TextField(Find.ById("application_description")).TypeText(description); currentBrowser.TextField(Find.ById("application_url")).TypeText(appUrl); currentBrowser.RadioButton(Find.ById("client_application_desktop_1")).Click(); currentBrowser.RadioButton(Find.ById("client_application_is_writable_1")).Click(); WatiN.Core.Image captchaImage = currentBrowser.Div(Find.ById("recaptcha_image")).Image(Find.ByStyle("display", "block")); Form2 captcha = new Form2(captchaImage.Src); captcha.ShowDialog(); } } } The exception is thrown on this line: currentBrowser.TextField(Find.ById("username")).TypeText(username); BUT, it's thrown when it gets to this line: captcha.ShowDialog(); It logs in, and fills in the app details and Form2 loads fine, but once loaded, after around 2-3 seconds the exception happens. I am wondering if it's anything to do with the threads? But I wouldn't know how to solve it if it was. The complete exception thrown is: The object invoked has disconnected from its clients. (Exception from HRESULT: 0x80010108 (RPC_E_DISCONNECTED))

  • nVidia Driver - Laptop is forced as one of my monitors

    - by vaccano
    I am trying to get my nVidia Driver to correctly configure my multi-monitor setup. I have my laptop in a docking station and two monitors hooked up to it. I had an old driver that this worked correctly with. However, that driver was causing a lot of "Deferred Procedure Calls" so I upgraded to a newer driver. But now I am forced to use my Laptop monitor as one of my monitors. Here is the image in the nVida Control Panel: As you can see, both monitors are recognized, but the only options available are to use one of them with the Laptop Display. Any Ideas? I am running Windows XP (latest updates), I have an nVidia Quadro 1500M. I have tried several different driver versions and all the new ones have this issue.

  • How do I delete a signature from an Excel document using Office automation

    - by Guy Marom
    Hello, I have a signed Excel workbook and I want to delete the signature from it. The problem is that when I try to delete the signature there's a prompt for confirming the deletion and I want the process to be fully automatic. Here's a code sample, the prompt appears when the last line executes: Dim source As String = "c:\temp\signed.xlsx" Dim app As New Application() app.Visible = True Dim book As Workbook = app.Workbooks.Open(source, UpdateLinks:=0) app.ShowToolTips = False Dim sig As Microsoft.Office.Core.Signature = book.Signatures.Item(1) sig.Delete() Thanks

  • In what way does non-"full n-key rollover" hinder fast typists?

    - by Michael Kjörling
    Wikipedia claims (although the latter claim does not cite a source) that: High-end keyboards that provide full n-key rollover typically do so via a PS/2 interface as the USB mode most often used by operating systems has a maximum of only six keys plus modifiers that can be pressed at the same time.[4] This hinders fast typists, ... In what way would the system being able to recognize only six non-modifier keys at once hinder a fast typist? I consider myself a relatively fast typist and I usually press one key, plus modifiers, at once; I can't imagine any real-life situation in which the system only recognizing six non-modifier keys being pressed at once has been a limiting factor in my keyboard usage. (Multi-stroke keyboard shortcuts as used by high-end software like Visual Studio, Emacs and the like are a different matter.) Note that I am not really interested in answers centered around multiplayer computer games; I'm looking for answers that give reasons that would be relevant to typists, somehow supporting the statement made on Wikipedia.

  • Is Minus Zero some sort of JavaScript performance trick?

    - by James Wiseman
    Looking in the jQuery core I found the folloiwng code convention: nth: function(elem, i, match){ return match[3] - 0 === i; }, And I was really curious about the snippet match[3] - 0 Hunting around for '-0' on google isn't too productive, and a search for 'minus zero' brings back a reference to a Bob Dylan song. So, can anyone tell me. Is this some sort of performance trick, or is there a reason for doing this rather than a parseInt or parseFloat? Thanks

  • Should I Use PHP as FastCGI?

    - by Synetech inc.
    Hi, I am running an Apache webserver on my Windows machine. It is not generally a public server (most of the little bit of traffic comes from the machine itself, and most of the public traffic comes from crawlers). Basically, it is mostly just for use as a test-bed, development system. I have read about how running PHP as FastCGI is better (ie faster and more stable) than as an Apache module. However, I really don’t like the idea of multiple PHP.exe processes (I don’t like that Apache has two processes and I’m not even too thrilled with Chromium’s multi-process model). So I’m wondering if it would be worthwhile to change PHP to FastCGI for this scenario. If it is, how would I configure it? Pretty much all of the information I have seen has been either for non-Windows or for IIS. As I said, I’m running Windows+Apache. Thanks a lot.

  • Can GPU capabilities impact virtual machine performance?

    - by Dave White
    While this many not seem like a programming question directly, it impacts my development activities and so it seems like it belongs here. It seems that more and more developers are turning to virtual environments for development activities on their computers, SharePoint development being a prime example. Also, as a trainer, I have virtual training environments for all of the classes that I teach. I recently purchased a new Dell E6510 to travel around with. It has the i7 620M (Dual core, HyperThreaded cpu running at 2.66GHz) and 8 GB of memory. Reading the spec sheet, it sounded like it would be a great laptop to carry around and run virtual machines on. Getting the laptop though, I've been pretty disappointed with the user experience of developing in a virtual machine. Giving the Virtual Machine 4 GB of memory, it was slow and I could type complete sentences and watch the VM "catchup". My company has training laptops that we provide for our classes. They are Dell Precision M6400 Intel Core 2 Duo P8700 running at 2.54Ghz with 8 GB of memory and the experience on this laptops is night and day compared to the E6510. They are crisp and you barely aware that you are running in a virtual environment. Since the E6510 should be faster in all categories than the M6400, I couldn't understand why the new laptop was slower, so I did a component by component comparison and the only place where the E6510 is less performant than the M6400 is the graphics department. The M6400 is running a nVidia FX 2700m GPU and the E6510 is running a nVidia 3100M GPU. Looking at benchmarks of the two GPUs suggest that the FX 2700M is twice as fast as the 3100M. http://www.notebookcheck.net/Mobile-Graphics-Cards-Benchmark-List.844.0.html 3100M = 111th (E6510) FX 2700m = 47th (Precision M6400) Radeon HD 5870 = 8th (Alienware) The host OS is Windows 7 64bit as is the guest OS, running in Virtual Box 3.1.8 with Guest Additions installed on the guest. The IDE being used in the virtual environment is VS 2010 Premium. So after that long setup, my question is: Is the GPU significantly impacting the virtual machine's performance or are there other factors that I'm not looking at that I can use to boost the vm's performance? Do we now have to consider GPU performance when purchasing laptops where we expect to use virtualized development environments? Thanks in advance. Cheers, Dave

  • Why do my download speeds drastically vary during a download?

    - by J. Anthony Carter
    I watch the download speed rise and fall like waves in a storm. At night, during low bandwidth usage I have achieve speeds as high as 3.23 M/sec but the watch them decline to 250 K/sec. and then climb back up. Over and over. During the day my best is around 1.67 M/sec with lows into the 65 K/sec. On top of this, why does a download need to slow down when approaching the end of the download? It's not like a multi-hundred ton train needing to decrease speed as it approaches the station.

  • Linux: How to break a large file into smaller files?

    - by Runcible
    I have a giant file (20 gigs) sitting on my source machine and I need to transfer it to my target machine. For the purposes of this question, let's assume that I do not have network connectivity between the two machines. I need to break this file into a series of smaller files, write the smaller files to DVD(s), then re-assemble everything on the target machine. Both source and destination machines are Linux boxes. Is there a way to accomplish this using tar? I have a feeling that I need to use the --multi-volume parameter. What are my options? I need to be able to specify the size of the volume files, in order to make sure that each one will fit onto a single DVD. Thanks!
