  • How to switch data pins on/off on parallel port?

    - by Matt
    I want to simply switch certain data pins on and off, so that they can control a set of relays. I'm not asking about the hardware bit (should be easy), but I don't know where to begin writing the software. I don't want a high level library that can send bytes to a device - I literally want to switch on/off certain pins. I'm running Linux and I want to do this in Java, so would I just need a library? It would be nice if the library has good documentation and is easy to use, but if not then a short example code will help me get started.

  • How to open a text file that's not in the same folder?

    - by nunos
    Since C it's not a language I am used to program with, I don't know how to do this. I have a project folder where I have all the .c and .h files and a conf folder under which there is a config.txt file to read. How can I open that? FILE* fp = fopen("/conf/config.txt"); if (fp != NULL) { //do stuff } else printf("couldn't open file\n"); I keep getting the error message. Why? Thanks.

  • Reading line by line from a file in C

    - by mh234
    What I am trying to do is print out the contents of a file line by line. I run the program in terminal by doing: ./test testText.txt. When I do this, random characters are printed out but not what is in the file. The text file is located in the same folder as the makefile. What's wrong? #include <stdio.h> FILE *fp; int main(int argc, char *argv[]) { char line[15]; fp = fopen(*argv, "r"); while((fgets(line, 15, fp)) != NULL) { printf(line); printf("\n"); } }

  • How do I do this in Python (File Manipulation)?

    - by ThinkCode
    I have a bunch of HTML files in HTML folder. Those HTML files have unicode characters which I solved by using filter(lambda x: x in string.printable, line). Now how do I write the changes back to the original file? What is the best way of doing it? Each HTML file is of 30 kb in size. 1 import os, string 2 3 for file in os.listdir("HTML/"): 4 print file 5 myfile = open('HTML/' + file) 6 fileList = myfile.readlines() 9 for line in fileList: 10 #print line 11 line = filter(lambda x: x in string.printable, line) 12 myfile.close()

  • Read All Files in Directory?

    - by cam
    How would I go about reading all files in a directory? In C# I would get a DirectoryInfo object, and get all files into a FileInfo[] object. Is there similar functionality in the STD namespace in C++?

  • Removing words from a file

    - by user1765792
    I'm trying to take a regular text file and remove words identified in a separate file (stopwords) containing the words to be removed separated by carriage returns ("\n"). Right now I'm converting both files into lists so that the elements of each list can be compared. I got this function to work, but it doesn't remove all of the words I have specified in the stopwords file. Any help is greatly appreciated. def elimstops(file_str): #takes as input a string for the stopwords file location stop_f = open(file_str, 'r') stopw = stop_f.read() stopw = stopw.split('\n') text_file = open('sample.txt') #Opens the file whose stop words will be eliminated prime = text_file.read() prime = prime.split(' ') #Splits the string into a list separated by a space tot_str = "" #total string i = 0 while i < (len(stopw)): if stopw[i] in prime: prime.remove(stopw[i]) #removes the stopword from the text else: pass i += 1 # Creates a new string from the compilation of list elements # with the stop words removed for v in prime: tot_str = tot_str + str(v) + " " return tot_str

  • BufferedInputStream.read(byte[]) Causes problems. Anyone have this problem before?

    - by K-RAN
    Hello! I've written a Java program that downloads audio files for me and I'm using BufferedInputStream. The read() function works fine but is really slow so I've tried using the overloaded version using byte[]. For some reason, the audio becomes lossy and strange after download. I'm not totally sure what I'm doing wrong so any help is appreciated! Here's the simplified, sloppy version of the code. BufferedInputStream bin = new BufferedInputStream((new URL(url)).openConnection().getInputStream()); File file = new File(fileName); FileOutputStream fop = new FileOutputStream(file); int rd = bin.read(); while(rd != -1) { fop.write(rd); rd = bin.read(); }

  • using std::freopen to redirect stderr c++

    - by chriscisco
    So I want to redirect all stderr to a file, which is also being used by my logger for the entire time the application (game) is running. The follow redirect it away from the console, but it never appears in my file, and using fclose after the game loop is over doesnt actually do anything, where it would normally would. freopen(Logger::logFile.c_str(),"a",stderr); Any help would be great on how to get stderr to output to the text file, in a game loop.

  • Why is this writing part of the text to a new line? (Python)

    - by whatsherface
    I'm adding some new bits to one of the lines in a text file and then writing it along with the rest of the lines in the file to a new file. Referring to the if statement, I that to be all on the same line: x = 13.55553e9 y = 14.55553e9 z = 15.55553e9 infname = 'afilename' outfname = 'anotherone' oldfile = open(infname) lnum=1 for line in oldfile: if (lnum==18): line = "{0:.2e}".format(x)+' '+line+' '+"{0:.2e}".format(y)+' '+ {0:.2e}".format(z) newfile = open(outfname,'w') newfile.write(line) lnum=lnum+1 oldfile.close() newfile.close() but y and z are being written on the line below the rest of it. What am I missing here?

  • Reading All Users Session

    - by imran_ku07
      Introduction :            InProc Session is the widely used state management. Storing the session state Inproc is also the fastest method and is well-suited to small amounts of volatile data. Reading and writing current user Session is very easy. But some times we need to read all users session before taking a decision or sometimes we may need to check which users are currently active with the help of Session. But unfortunately there is no class in .Net Framework (i don't found myself) to read all user InProc Session Data. In this article i will use reflection to read all user Inproc Session.   Description :              This code will work equally in both MVC and webform, but for demonstration i will use a simple webform example. So let's create a simple Website and Add two aspx pages, Default.aspx and Default2.aspx. In Default.aspx just add a link to navigate to Default2.aspx and in Default.aspx.cs just add a Session. Default.aspx: <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="Default" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html ><head runat="server">    <title>Untitled Page</title></head><body>    <form id="form1" runat="server">    <div>        <a href="Default2.aspx">Click to navigate to next page</a>    </div>    </form></body></html>  Default.aspx.cs:  using System;using System.Data;using System.Configuration;using System.Collections;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Web.UI.HtmlControls;public partial class Default : System.Web.UI.Page{    protected void Page_Load(object sender, EventArgs e)    {        Session["User"] = "User" + DateTime.Now;    }} Now when every user click this link will navigate to Default2.aspx where all the magic appears.Default2.aspx.cs: using System;using System.Data;using System.Configuration;using System.Collections;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Web.UI.HtmlControls;using System.Reflection;using System.Web.SessionState;public partial class Default2 : System.Web.UI.Page{    protected void Page_Load(object sender, EventArgs e)    {        object obj = typeof(HttpRuntime).GetProperty("CacheInternal", BindingFlags.NonPublic | BindingFlags.Static).GetValue(null, null);        Hashtable c2 = (Hashtable)obj.GetType().GetField("_entries", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(obj);        foreach (DictionaryEntry entry in c2)        {            object o1 = entry.Value.GetType().GetProperty("Value", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(entry.Value, null);            if (o1.GetType().ToString() == "System.Web.SessionState.InProcSessionState")            {                SessionStateItemCollection sess = (SessionStateItemCollection)o1.GetType().GetField("_sessionItems", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(o1);                if (sess != null)                {                    if (sess["User"] != null)                    {                        Label1.Text += sess["User"] + " is Active.<br>";                    }                }            }        }    }}            Now just open more than one browsers or more than one browser instance and then navigate to Default.aspx and click the link, you will see all the user's Session data.    How this works :        InProc session data is stored in the HttpRuntime’s internal cache in an implementation of ISessionStateItemCollection that implements ICollection. In this code, first of all i got CacheInternal Static Property of HttpRuntime class and then with the help of this object i got _entries private member which is of type ICollection. Then simply enumerate this dictionary and only take object of type System.Web.SessionState.InProcSessionState and finaly got SessionStateItemCollection for each user.Summary :        In this article, I shows you how you can get all current user Sessions. However one thing you will find when executing this code is that it will not show the current user Session which is set in the current request context because Session will be saved after all the Page Events.

  • What's hogging my CPU?

    - by endolith
    Ubuntu's System Monitor applet shows 100% CPU usage continuously. If I click it, the resources tab shows it at 100% continuously, too. If I go to processes, though, to find out which process is the culprit, there is nothing above 10%. If I run top there is nothing above 10%. I try killing lots of things, but it continues at 100%. How can I find out what's hogging the CPU? This is an unusual situation on a computer I use daily, that normally only hits 100% CPU when I'm doing something that requires it (like loading 32 Firefox tabs) after which it goes back to a normal idle level. It's not a new install or anything. It shouldn't be maxed out. I'm not sure when it started or if I changed something that caused it to happen. Normally I would use top or System Monitor and find the process that had gone out of control, but I can't find anything with those tools this time. It persists after reboots and everything. And the processor is obviously hot, so it's not an erroneous reading. Update: I tried killing any process I saw active again, and killing vino-server finally fixed the problem, even though it never went above 5%. I had enabled Remote Desktop a few days ago (and have obviously now disabled it). How did it manage to use 100% CPU while top only showed it as 5% or so? How do I identify the culprit in the future? Looks like I'm not the only one: Still a problem in both jaunty & karmic. Interestingly, both System Monitor & htop do not show the sum of individual processes being anywhere near 100% cpu.

  • Problems with Windows 7 restore

    - by Chris Lively
    My WD raptor 150 failed with a nice clicking noise. So, I picked up a velociraptor 300 and popped it in. I had windows set to do a full system backup nightly, so I figured the recovery ought to go easily. Well, it isn't. It is currently stuck on a screen that says: "Windows is restoring your computer from the system image. This might take from a few minutes to a few hours" Below that is a rather large progress meter with maybe the first block filled in. Below that is a message that says "Restoring disk (C:)..." It's been that way for over an hour. The first time around, I gave up after 2 hours. I then booted into the system recovery options and went to a command prompt and ran a chkdsk on the new drive. It showed several file inconsistencies and not much else. I ran a chkdsk /f on it and tried again... Which is where I'm at now. I can't see that the restore process should take this long before. Any ideas? UPDATE After 10 hours, it's still on "Restoring disk (C:)" and the progress meter is at roughly 5%. I'm guessing at the 5% as there isn't an actual number or anything else that I can look at showing what it's actually doing. The backup contains roughly 120GB of data. How slow is windows restore?

  • BSOD error 0x0000006B PROCESS1_INITIALIZATION_FAILED on boot

    - by DontCare4Free
    I reinstalled League of Legends because the patcher always gave me an error. However, out of complete stupidness I didn't uninstall the old installation first because I thought that it would simply replace the files. However, when the installer bar got to 100% it simply minimized. Then I closed the application from the task manager. I tried uninstalling it after a failed attempt to start it up. The same behavior as when I installed it. Then I tried reinstalling where it simply presented the InstallShield Modify/Repair/Remove menu and I selected repair. Nothing happened. Then I tried selecting Modify, then seeing that the only option (called DefaultFeature) was unchecked. Same behaviour as install/uninstall. After seeing that it still failed, I uninstalled again. And after that I deleted C:\Program Files (x86)\League of Legends manually. When I tried installing LoL again it still thought I had it, so I chose repair. This time something actually happened, but it installed the whole game to C:\Windows. Seeing what was going on I clicked cancel and then started it up to try uninstalling it. However, I got an error message about something not being registered and then the minimization to I decided to let it repair completely. Then I uninstalled it and it gave only the minimization. However, when I rebooted another application started up complaining about some library being absent. So I decided to do a system restore. After letting it complete I got a BSOD every time I tried starting up Windows normally or in safe mode. However, system recovery mode works, although the system recovery automatic repair does not fix it. After a bit of searching I found a Microsoft KB article about it (981833) and tried following the workaround instructions. Nothing happened. I am using Windows 7 Home Premium 64-bit and Ubuntu 10.04 LTS 64-bit installed with WUBI.

  • Did Windows 7 Startup Repair trash My Documents?

    - by Metaphile
    Earlier today, I rebooted my computer. Partway through the boot process, it shut down suddenly. When I tried again, I was prompted to run Startup Repair, and I did. Afterwards, my computer booted normally and everything seemed to be in order. Then I noticed that my My Documents folder contains a mix of old and new files. On closer inspection, it appears that Windows has reverted my system to a previous state. Two things puzzle me: 1) According to Microsoft, "System Restore does not affect personal files, such as e-mail, documents, or photos [...]", yet many of my personal files have been affected. 2) Why were some things reverted, but not others? I had recently reorganized a bunch of files in My Documents. The reverted directory structure seems to be a hybrid of old a new, with a lot of new stuff missing. It's hard to say for sure, but it looks like the stuff that's missing would have been in conflict (two folders with the same name, for example), and Windows favored the old stuff. Is this normal behavior for Startup Repair/System Restore? To modify personal files, I mean? Is there a pattern to the mess it's made of My Documents?

  • Android Canvas Coordinate System

    - by Mitch
    I'm trying to find information on how to change the coordinate system for the canvas. I have some vector data I'd like to draw to a canvas using things like circles and lines, but the data's coordinate system doesn't match the canvas coordinate system. Is there a way to map the units I'm using to the screen's units? I'm drawing to an ImageView which isn't taking up the entire display. If I have to do my own calculations prior to each drawing call, how to I find the width and height of my ImageView? The getWidth() and getHeight() calls I tried seem to be returning the entire canvas size and not the size of the ImageView which isn't helpful. I see some matrix stuff, is that something that will work for me? I tried to use the "public void scale(float sx, float sy)", but that works more like a pixel level zoom rather than a vector scale function by expanding each pixel. This means if the dimensions are increased to fit the screen, the line thickness is also increased. Update: After some research I'm starting to think there's no way to change coordinate systems to something else. I'll need to map all my coordinates to the screen's pixel coordinates and do so by modifying each vector. The getWidth() and getHeight() seem to be working better for me now. I can say what was wrong, but I suspect I can't use these methods inside the constructor.

  • System.Net.WebClient doesn't work with Windows Authentication

    - by Peter Hahndorf
    I am trying to use System.Net.WebClient in a WinForms application to upload a file to an IIS6 server which has Windows Authentication as it only 'Authentication' method. WebClient myWebClient = new WebClient(); myWebClient.Credentials = new System.Net.NetworkCredential(@"boxname\peter", "mypassword"); byte[] responseArray = myWebClient.UploadFile("http://localhost/upload.aspx", fileName); I get a 'The remote server returned an error: (401) Unauthorized', actually it is a 401.2 Both client and IIS are on the same Windows Server 2003 Dev machine. When I try to open the page in Firefox and enter the same correct credentials as in the code, the page comes up. However when using IE8, I get the same 401.2 error. Tried Chrome and Opera and they both work. I have 'Enable Integrated Windows Authentication' enabled in the IE Internet options.

  • "cloud architecture" concepts in a system architecture diagrams

    - by markus
    If you design a distributed application for easy scale-out, or you just want to make use of any of the new “cloud computing” offerings by Amazon, Google or Microsoft, there are some typical concepts or components you usually end up using: distributed blob storage (aka S3) asynchronous, durable message queues (aka SQS) non-Relational-/non-transactional databases (like SimpleDB, Google BigTable, Azure SQL Services) distributed background worker pool load-balanced, edge-service processes handling user requests (often virtualized) distributed caches (like memcached) CDN (content delivery network like Akamai) Now when it comes to design and sketch an architecture that makes use of such patterns, are there any commonly used symbols I could use? Or even a download with some cool Visio stencils? :) It doesn’t have to be a formal system like UML but I think it would be great if there were symbols that everyone knows and understands, like we have commonly used shapes for databases or a documents, for example. I think it would be important to not mix it up with traditional concepts like a normal file system (local or network server/SAN), or a relational database. Simply speaking, I want to be able to draw some conclusions about an application’s scalability or data consistency issues by just looking at the system architecture overview diagram. Update: Thank you very much for your answers. I like the idea of putting a small "cloud symbol" on the traditional symbols. However I leave this thread open just in case someone will find specific symbols (maybe in a book or so) - or uploaded some pimped up Visio stencils ;)

  • System.InvalidOperationException: Failed to map the path '/sharedDrive/Public'

    - by d03boy
    I'm trying to set up a page that will allow users to download files from a shared drive (where the file is actually sent via the page). So far this is what I have. public partial class TestPage : System.Web.UI.Page { protected DirectoryInfo dir; protected FileInfo[] files; protected void Page_Load(object sender, EventArgs e) { dir = new DirectoryInfo(Server.MapPath(@"\\sharedDrive\Public")); files = dir.GetFiles(); } } The aspx page looks kind of like this: <% Response.Write(System.Security.Principal.WindowsIdentity.GetCurrent().Name); %> <ul> <% foreach (System.IO.FileInfo f in files) { Response.Write("<li>" + f.FullName + "</li>"); } %> </ul> When I remove the erroneous parts of the code, the page tells me that the Windows Identity I'm using is my user (which has access to the drive). I don't understand what the problem could be or what it's even complaining about.

  • System.Web.Caching vs. Enterprise Library Caching Block

    - by ESV
    For a .NET component that will be used in both web applications and rich client applications, there seem to be two obvious options for caching: System.Web.Caching or the Ent. Lib. Caching Block. What do you use? Why? System.Web.Caching Is this safe to use outside of web apps? I've seen mixed information, but I think the answer is maybe-kind-of-not-really. a KB article warning against 1.0 and 1.1 non web app use The 2.0 page has a comment that indicates it's OK: http://msdn.microsoft.com/en-us/library/system.web.caching.cache(VS.80).aspx Scott Hanselman is creeped out by the notion The 3.5 page includes a warning against such use Rob Howard encouraged use outside of web apps I don't expect to use one of its highlights, SqlCacheDependency, but the addition of CacheItemUpdateCallback in .NET 3.5 seems like a Really Good Thing. Enterprise Library Caching Application Block other blocks are already in use so the dependency already exists cache persistence isn't necessary; regenerating the cache on restart is OK Some cache items should always be available, but be refreshed periodically. For these items, getting a callback after an item has been removed is not very convenient. It looks like a client will have to just sleep and poll until the cache item is repopulated. Memcached for Win32 + .NET client What are the pros and cons when you don't need a distributed cache?
