  • Linking buttion to jQuery through service

    - by Ruddy
    I have a small problem that should be very easy to overcome. For some reason I cant work this out. So the problem is I cannot get a button to link to some jquery. My set-up is as follows (showing the relevant code): Default.aspx jQuery: function getContent() { var data = { numberID: 1 }; $.jsonAspNet("ContentService.asmx", "GetContent", data, function (result) { $('#content').html(result); }); } jQuery(document).ready(function () { getContent(); } HTML: <div id="content"></div> ContentService.vb Public Function GetContent(number As Integer) As String Dim sb = New StringBuilder sb.AppendLine("<table>") sb.AppendLine("<tr>") sb.AppendLine("<td class='ui-widget-header ui-corner-all'>Number</td>") sb.AppendLine("</tr>") sb.AppendLine("<tr>") sb.AppendLine("<td>" & number & "</td>") sb.AppendLine("<td><a href='#' id='test' class='fg-button ui-state-default ui-corner-all'><img src='" & Context.Request.ApplicationPath & "/images/spacer.gif' class='ui-icon ui-icon-pencil' /></a></td>") sb.AppendLine("</tr>") sb.AppendLine("</table>") Return sb.ToString End Function So that's the basics of what I have everything works but I'm not sure how to get the button (id='test') to get linked to some jQuery. I want it to be pressed and bring up a popup. I have tried to put the jQuery on default.aspx but this doesn't seem to work unless the button is place in the HTML on that page. $('#test').unbind('click').click(function () { alert('Working'); }); I'm sure this is easy to be able to do but I have been trying for a while and cannot seem to get it to work.

  • Help with Neuroph neural network

    - by user359708
    For my graduate research I am creating a neural network that trains to recognize images. I am going much more complex than just taking a grid of RGB values, downsampling, and and sending them to the input of the network, like many examples do. I actually use over 100 independently trained neural networks that detect features, such as lines, shading patterns, etc. Much more like the human eye, and it works really well so far! The problem is I have quite a bit of training data. I show it over 100 examples of what a car looks like. Then 100 examples of what a person looks like. Then over 100 of what a dog looks like, etc. This is quite a bit of training data! Currently I am running at about one week to train the network. This is kind of killing my progress, as I need to adjust and retrain. I am using Neuroph, as the low-level neural network API. I am running a dual-quadcore machine(16 cores with hyperthreading), so this should be fast. My processor percent is at only 5%. Are there any tricks on Neuroph performance? Or Java peroformance in general? Suggestions? I am a cognitive psych doctoral student, and I am decent as a programmer, but do not know a great deal about performance programming.

  • Problem with python urllib

    - by mudder
    I'm getting an error when ever I try to pull down a web page with urllib.urlopen. I've disabled windows firewall and my AV so its not that. I can access the pages in my browser. I even reinstalled python to rule out it being a broken urllib. Any help would be greatly appreciated. >>> import urllib >>> h = urllib.urlopen("http://www.google.com").read() Traceback (most recent call last): File "<pyshell#1>", line 1, in <module> h = urllib.urlopen("http://www.google.com").read() File "C:\Python26\lib\urllib.py", line 86, in urlopen return opener.open(url) File "C:\Python26\lib\urllib.py", line 205, in open return getattr(self, name)(url) File "C:\Python26\lib\urllib.py", line 344, in open_http h.endheaders() File "C:\Python26\lib\httplib.py", line 904, in endheaders self._send_output() File "C:\Python26\lib\httplib.py", line 776, in _send_output self.send(msg) File "C:\Python26\lib\httplib.py", line 735, in send self.connect() File "C:\Python26\lib\httplib.py", line 716, in connect self.timeout) File "C:\Python26\lib\socket.py", line 514, in create_connection raise error, msg IOError: [Errno socket error] [Errno 10061] No connection could be made because the target machine actively refused it >>>

  • How to terminate all [grand]child processes using C# on WXP (and newer MSWindows)

    - by NVRAM
    Question: How can I determine all processes in the child's Process Tree to kill them? I have an application, written in C# that will: Get a set of data from the server, Spawn a 3rd party utility to process the data, then Return the results to the server. This is working fine. But since a run consumes a lot of CPU and may take as long as an hour, I want to add the ability to have my app terminate its child processes. Some issues that make the simple solutions I've found elsewhere are: My app's child process "A" (InstallAnywhere EXE I think) spawns the real processing app "B" (a java.exe), which in turns spawns more children "C1".."Cn" (most of which are also written in Java). There will likely be multiple copies of my application (and hence, multiple sets of its children) running on the same machine. The child process is not in my control so there might be some "D" processes in the future. My application must run on 32-bit and 64-bit versions of MSWindows. On the plus side there is no issue of data loss, a "clean" shutdown doesn't matter as long as the processes end fairly quickly.

  • Agilent E4426B signal generator locks up during multiple GPIB *SAV operations

    - by aspiehler
    I have a test fixture with an Agilent E4426B RF signal generator connected to a PC via a National Instrument Ethernet-to-GPIB bridge. My software is attempting to sanitize the instrument by presetting it and then saving the current state to all of the memory locations writable via the standard SCPI command "*SAV x,y". The loop works to a point, but eventually the instrument responds with an error and continuously displays the "L" icon on the front display and a "Remote preset" message at the bottom. At that point it won't respond to any more remote commands and I have to either cycle power or press LOCAL, then PRESET at which point it takes about 3 minutes to finish presetting. At that point the "L" icon is still present and and the next GPIB command sent to the instrument causes it to report a -113 error (undefined header) in the instrument error queue. I fired up NI spy to see what was happening, and found that the error was happening at the same point in the loop - "*SAV 6,2" in this case. From NI Spy: Send (0, 0x0017, "*SAV 6,2", 8 (0x8), NLend (0,0x01)) Process ID: 0x00000520 Thread ID: 0x00000518 ibsta:0xc168 iberr: 6 ibcntl: 2(0x2) And here's the code from the instrument driver: int CHP_E4426b::Erase() { if ((m_StatusCode = Initialize()) != GPIB_SUCCESS) // basically just sends "*RST" return m_StatusCode; m_SaveState = "*SAV %d, %d"; for (int i=0; i < 10; i++) for (int j=0; j < 100; j++) { sprintf(m_CmdString, m_SaveState, j, i); if ((m_StatusCode = Send(m_CmdString, strlen(m_CmdString))) != GPIB_SUCCESS) return m_StatusCode; } return GPIB_SUCCESS; } I tried putting a small Sleep() delay (10-20 ms) at the end of the inner loop, and to my surprise it caused the error to show up earlier rather than later. 10 ms caused the loop to error out at 44,1 and 20 ms was even sooner. I've already eliminated faulty cabling or the instrument as the culprit. This same type of sequence works without any error on a higher end signal generator, so I'm tempted to chalk this up to a bug in the instrument's firmware.

  • Reusing Windows Picture and Fax Viewer process to load a new image from FileSystemWatcher

    - by Cory Larson
    So for an idea for my birthday party I'm setting up a photo booth. I've got software to remotely control the camera and all that, but I need to write a little application to monitor the folder where the pictures get saved and display them. Here's what I've got so far. The issue is that I don't want to launch a new Windows Photo Viewer process every time the FileSystemWatcher sees a new file, I just want to load the latest image into the current instance of the Windows Photo Viewer (or start a new one if one isn't running). class Program { static void Main(string[] args) { new Program().StartWatching(); } public void StartWatching() { FileSystemWatcher incoming = new FileSystemWatcher(); incoming.Path = @"G:\TempPhotos\"; incoming.NotifyFilter = NotifyFilters.LastWrite | NotifyFilters.FileName; incoming.Filter = "*.jpg"; incoming.Created += new FileSystemEventHandler(ShowImage); incoming.EnableRaisingEvents = true; Console.WriteLine("Press \'q\' to quit."); while (Console.Read() != 'q') ; } private void ShowImage(object source, FileSystemEventArgs e) { string s1 = Environment.ExpandEnvironmentVariables("%windir%\\system32\\rundll32.exe "); string s2 = Environment.ExpandEnvironmentVariables("%windir%\\system32\\shimgvw.dll,ImageView_Fullscreen " + e.FullPath); Process.Start(s1, s2); Console.WriteLine("{0} : Image \"{0}\" at {1:t}.", e.ChangeType, e.FullPath, DateTime.Now); } } If you don't have a tried and true solution, a simple push in the right direction would be just as valuable. And FYI, this will be running on a 64-bit Windows 7 machine. Thanks!

  • Why do I get "Error 6060" when I try to use DBD::Advantage with a 64-bit perl on Linux?

    - by WarheadsSE
    I realize that I am attempting to go beyond the "supported" behavior of the manf's released drivers for Perl, after all they have only released it in package with x86 .so's. However, since I cannot use their package with x64 Perl on a RHEL 5.4 x86_64 box, and maintaining a seperate install of x86 Perl just for this one package, I have made an attempt to get this puppy working thanks to released 64-bit .so's that accompany other driver packages for Advantage. What I have done to this point: download beta 10 DBI drivers, in 32 download beta 10 PHP extension (it contains 32 and x86_64) copy the required DLLs into the ads-lib location (eg /usr/local/ads/lib64) compile the Perl DBI driver with the path to the lib64's .so's Good compilation, good install, good use. The problem is that I always get : failed: [iAnywhere Solutions][Advantage SQL][ASA] Error 6060: Advantage Database Server not available on specified server. axServerConnect (SQL-HY000)(DBD: db_login/SQLConnect err=-1) Does anyone have any ideas? EDIT: fixed package name in post title EDIT: Updated title. It appears that it's not just the x64 perl, but the RHEL 5.4 underneath that may be interfering. As commented below, I managed to shoe-horn a x86 perl onto the system, and compile the DBD::Advantage 9.99, and later replacing that with 9.10, and none of these x86 would connect either. Neither library (9.99 or 9.10) in either bit-edness will connect from this x86_64 server to the windows server's UNC path. I have successfully mounted this share without problems, but still I cannot seem to connect to the 9.1. I have tried: \hostname\PATH \FQDN\PATH \IP\PATH and all of these variations with the port (default) 6262 included. My windows machine connects fine, with both 9.1 and 9.99 from strawberry perl.

  • Unpacking gems [Rails 2.3.5]

    - by yuval
    I have the following gems defined in my environment.rb file: config.gem "authlogic" config.gem "paperclip" config.gem "pauldix-feedzirra", :lib => "feedzirra", :source => "http://gems.github.com" config.gem 'whenever', :lib => false, :source => 'http://gemcutter.org/' I have them installed on my local computer and everything is working well. Since I am working on a shared-server (DreamHost), I need to unpack those gems to get them to work (can't install them as I did on my own computer to get them to work). Before uploading, I ran the following on my local machine: rake gems:unpack This created the following folders in /vender/gems: authlogic-2.1.3, paperclip-2.3.1.1, pauldix-feedzirra-0.0.18, whenever-0.4.1 So it looks like they're all there. When I run rake db:migrate on the server, though, I get these following error: Missing these required gems: pauldix-feedzirra For some reason, the feedzirra unpacked gem is not detected. Could anybody give me a clue as to why this is happening and how to solve it? Thanks!

  • .NET JIT Code Cache leaking?

    - by pitchfork
    We have a server component written in .Net 3.5. It runs as service on a Windows Server 2008 Standard Edition. It works great but after some time (days) we notice massive slowdowns and an increased working set. We expected some kind of memory leak and used WinDBG/SOS to analyze dumps of the process. Unfortunately the GC Heap doesn’t show any leak but we noticed that the JIT code heap has grown from 8MB after the start to more than 1GB after a few days. We don’t use any dynamic code generation techniques by our own. We use Linq2SQL which is known for dynamic code generation but we don’t know if it can cause such a problem. The main question is if there is any technique to analyze the dump and check where all this Host Code Heap blocks that are shown in the WinDBG dumps come from? [Update] In the mean time we did some more analysis and had Linq2SQL as probable suspect, especially since we do not use precompiled queries. The following example program creates exactly the same behaviour where more and more Host Code Heap blocks are created over time. using System; using System.Linq; using System.Threading; namespace LinqStressTest { class Program { static void Main(string[] args) { for (int i = 0; i < 100; ++ i) ThreadPool.QueueUserWorkItem(Worker); while(runs < 1000000) { Thread.Sleep(5000); } } static void Worker(object state) { for (int i = 0; i < 50; ++i) { using (var ctx = new DataClasses1DataContext()) { long id = rnd.Next(); var x = ctx.AccountNucleusInfos.Where(an => an.Account.SimPlayers.First().Id == id).SingleOrDefault(); } } var localruns = Interlocked.Add(ref runs, 1); System.Console.WriteLine("Action: " + localruns); ThreadPool.QueueUserWorkItem(Worker); } static Random rnd = new Random(); static long runs = 0; } } When we replace the Linq query with a precompiled one, the problem seems to disappear.

  • Debugging in VS 2008 locks a stored procedure

    - by larryq
    Hi everyone, I've got a strange one here. I have a .Net executable that, under the hood, calls a few stored procedures. For whatever reason, one of the stored procs hangs when I'm debugging. If I run the executable outside of visual studio things go fine, including this stored proc. It's when I'm debugging that this hangs, and it really hangs. If I stop the debugging session the IDE freezes and I have to kill it via taskmanager. I know which stored procedure has the trouble, as well as the actual statement within it that's the problem. It's calling an update statement that doesn't stand out as particularly special. I can run the identical statement (and the stored procedure itself) from SQL management studio wtih no problem. And, as I mentioned, the exe runs just fine outside the debugger. If I use the SQL activity monitor to see why things are hanging, the wait type says PREEMPTIVE_DEBUG. I'm not sure if that's helpful but if you need more info I'll try to get it to you. I've rebooted my machine (the SQL Server in question is on this box as well) and that didn't do anything, nor did rebuilding the executable. I'm scratching my head on this one and if you have any ideas what to check on next, I'm be happy to listen. Thanks!

  • XSP2 crashes serving static images

    - by Dawkins
    Hi, Requesting a simple HTML page with a jpg image makes XSP2 crash. If I remove the image from the HTML then the page is served OK all the time. The version is XSP2 2.0 mono 2.6.1. the version 2.4.2.2 in the same machine works fine. I have tested it in two different machines, both Windows Vista Business SP1. Anyone has experienced the same? Any clue of what can be the problem? Below is the stack trace displayed by the console: (The line in Spanish says "it has been forced the interruption of an existing connection by the remote host") EDIT: since another user is having the same problem I have submited a bug to Novell and created a litle zip to reproduce the problem: https://bugzilla.novell.com/show_bug.cgi?id=582162 Peer unexpectedly closed the connection on write.

  • Fast sign in C++ float...are there any platform dependencies in this code?

    - by Patrick Niedzielski
    Searching online, I have found the following routine for calculating the sign of a float in IEEE format. This could easily be extended to a double, too. // returns 1.0f for positive floats, -1.0f for negative floats, 0.0f for zero inline float fast_sign(float f) { if (((int&)f & 0x7FFFFFFF)==0) return 0.f; // test exponent & mantissa bits: is input zero? else { float r = 1.0f; (int&)r |= ((int&)f & 0x80000000); // mask sign bit in f, set it in r if necessary return r; } } (Source: ``Fast sign for 32 bit floats'', Peter Schoffhauzer) I am weary to use this routine, though, because of the bit binary operations. I need my code to work on machines with different byte orders, but I am not sure how much of this the IEEE standard specifies, as I couldn't find the most recent version, published this year. Can someone tell me if this will work, regardless of the byte order of the machine? Thanks, Patrick

  • Memory Bandwidth Performance for Modern Machines

    - by porgarmingduod
    I'm designing a real-time system that occasionally has to duplicate a large amount of memory. The memory consists of non-tiny regions, so I expect the copying performance will be fairly close to the maximum bandwidth the relevant components (CPU, RAM, MB) can do. This led me to wonder what kind of raw memory bandwidth modern commodity machine can muster? My aging Core2Duo gives me 1.5 GB/s if I use 1 thread to memcpy() (and understandably less if I memcpy() with both cores simultaneously.) While 1.5 GB is a fair amount of data, the real-time application I'm working on will have have something like 1/50th of a second, which means 30 MB. Basically, almost nothing. And perhaps worst of all, as I add multiple cores, I can process a lot more data without any increased performance for the needed duplication step. But a low-end Core2Due isn't exactly hot stuff these days. Are there any sites with information, such as actual benchmarks, on raw memory bandwidth on current and near-future hardware? Furthermore, for duplicating large amounts of data in memory, are there any shortcuts, or is memcpy() as good as it will get? Given a bunch of cores with nothing to do but duplicate as much memory as possible in a short amount of time, what's the best I can do?

  • May volatile be in user defined types to help writing thread-safe code

    - by David Rodríguez - dribeas
    I know, it has been made quite clear in a couple of questions/answers before, that volatile is related to the visible state of the c++ memory model and not to multithreading. On the other hand, this article by Alexandrescu uses the volatile keyword not as a runtime feature but rather as a compile time check to force the compiler into failing to accept code that could be not thread safe. In the article the keyword is used more like a required_thread_safety tag than the actual intended use of volatile. Is this (ab)use of volatile appropriate? What possible gotchas may be hidden in the approach? The first thing that comes to mind is added confusion: volatile is not related to thread safety, but by lack of a better tool I could accept it. Basic simplification of the article: If you declare a variable volatile, only volatile member methods can be called on it, so the compiler will block calling code to other methods. Declaring an std::vector instance as volatile will block all uses of the class. Adding a wrapper in the shape of a locking pointer that performs a const_cast to release the volatile requirement, any access through the locking pointer will be allowed. Stealing from the article: template <typename T> class LockingPtr { public: // Constructors/destructors LockingPtr(volatile T& obj, Mutex& mtx) : pObj_(const_cast<T*>(&obj)), pMtx_(&mtx) { mtx.Lock(); } ~LockingPtr() { pMtx_->Unlock(); } // Pointer behavior T& operator*() { return *pObj_; } T* operator->() { return pObj_; } private: T* pObj_; Mutex* pMtx_; LockingPtr(const LockingPtr&); LockingPtr& operator=(const LockingPtr&); }; class SyncBuf { public: void Thread1() { LockingPtr<BufT> lpBuf(buffer_, mtx_); BufT::iterator i = lpBuf->begin(); for (; i != lpBuf->end(); ++i) { // ... use *i ... } } void Thread2(); private: typedef vector<char> BufT; volatile BufT buffer_; Mutex mtx_; // controls access to buffer_ };

  • Embedding/deploying custom font in .NET app

    - by Swingline Rage
    Is there an official way to distribute (deploy) a specific font with a .NET application? We have a (public domain) "LED font" that prints numbers with the retro LED instrumentface look. This is a standard True Type or Open Type font like any other except it looks funky. Obviously for that to work, this font needs to be on the user's machine. But we'd prefer to not force the user to "install our special font into your font folder". We'd prefer to either load a Font object directly from the TTF, or programatically install the font so it's available. How do applications handle this sort of things? Eg, I notice Adobe XYZ installs various fonts on the system without user intervention. That's what we'd like to do. EDIT: okay, ideally, we'd prefer not to install the font directly. We don't want our nifty themed LED font showing up in the user's font dropdown in MS Word. We'd prefer to use this font, but restrict its use or appearance to our app. Any way to do this? Thanks!

  • Is this scenario in compliance with GPLv3?

    - by Sean Kinsey
    For arguments sake, say that we create a web application , that depends on a GPLv3 licensed component, lets say Ext JS. Based on Section 0 of the license, the common notion is that the entire web application (the client side javascript) falls under the definition of a covered work: A “covered work” means either the unmodified Program or a work based on the Program. and that it will therefor have to be distributed under the same license Ok, so here comes the fun part: This is a short 'program' that is based on Ext JS var myPanel = new Ext.Panel(); The question that arises is: Have I now violated the GPL by not including the source of Ext JS and its license? Ok, so lets take another example <!doctype html> <html> <head> <title>my title</title> <script type="text/javascript" src="http://extjs.cachefly.net/ext-3.2.1/ext-all.js"> </script> <link rel="stylesheet" type="text/css" href="http://extjs.cachefly.net/ext-3.2.1/resources/css/ext-all.css" /> <script type="text/javascript"> var myPanel = new Ext.Panel(); </script> </head> <body> </body> </html> Have I now violated the terms of the GPL? The code conveyed by me to you is in a non-functional state - it will have to be combined with the actual source of Ext JS, which you(your browser) will have to retrieve, from a source made public by someone else to be usable. Now, if the answer to the above is no, how does me conveying this code in visible form differ from the 'invisible' form conveyed by my web server? As a side note, a very similar thing is done in Linux with many projects that depends on less permissive licenses - the user has to retrieve these on its own and make these available for the primary lib/executable. How is this not the same if the user is informed on beforehand that he (the browser) will have to retrieve the needed resources from a different source? Just to make it clear, I'm pro FLOSS, and I have also published a number of projects licensed under more permissive licenses. The reason I'm asking this is that I still haven't found anyone offering a definitive answer to this.

  • Accessing Virtual Host from outside LAN

    - by Ray
    I'm setting up a web development platform that makes things as easy as possible to write and test all code on my local machine, and sync this with my web server. I setup several virtual hosts so that I can access my projects by typing in "project" instead of "localhost/project" as the URL. I also want to set this up so that I can access my projects from any network. I signed up for a DYNDNS URL that points to my computer's IP address. This worked great from anywhere before I setup the virtual hosts. Now when I try to access my projects by typing in my DYNDNS URL, I get the 403 Forbidden Error message, "You don't have permission to access / on this server." To setup my virtual hosts, I edited two files - hosts in the system32/drivers/etc folder, and httpd-vhosts.conf in the Apache folder of my WAMP installation. In the hosts file, I simply added the server name to associate with 127.0.0.1. I added the following to the http-vhosts.conf file: <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot "c:/wamp/www/ladybug" ServerName ladybug ErrorLog "logs/your_own-error.log" CustomLog "logs/your_own-access.log" common </VirtualHost> <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot "c:/wamp/www" ServerName localhost ErrorLog "logs/localhost-error.log" CustomLog "logs/localhost-access.log" common </VirtualHost> Any idea why I can't access my projects from typing in my DYNDNS URL? Also, is it possible to setup virtual hosts so that when I type in http://projects from a random computer outside of my network, I access url.dyndns.info/projects (a.k.a. my WAMP projects on my home computer)? Help is much appreciated, thanks!

  • MVC Rendered Partial, how to get partial/view model in main model post to controller

    - by user1475788
    I have a text file and when users upload the file, the controller action method parses that file using state machine and uses a generic list to store some values. I pass this back to the view in the form of an IEnumerable. Within my main view, based on this ienumerable list I render a partail view to iterate items and display labels and a textarea. Users could add their input in the text area. When the users hit the save button this ienumrable list from the partial view rendered is null. so please advice any solutions. here is my main view @model RunLog.Domain.Entities.RunLogEntry @{ ViewBag.Title = "Create"; Layout = "~/Views/Shared/_Layout.cshtml"; } @using (Html.BeginForm("Create", "RunLogEntry", FormMethod.Post, new { enctype = "multipart/form-data" })) { <div id="inputTestExceptions" style="display: none;"> <table class="grid" style="width: 450px; margin: 3px 3px 3px 3px;"> <thead> <tr> <th> Exception String </th> <th> Comment </th> </tr> </thead> <tbody> @if (Model.TestExceptions != null) { foreach (var p in Model.TestExceptions) { Html.RenderPartial("RunLogTestExceptionSummary", p); } } </tbody> </table> </div> } partial view as follows: @model RunLog.Domain.Entities.RunLogEntryTestExceptionDisplay <tr> <td> @Model.TestException@ </td> <td>@Html.TextAreaFor(Model.Comment, new { style = "width: 200px; height: 80px;" }) </td> </tr> Controller action [HttpPost] public ActionResult Create(RunLogEntry runLogEntry, String ServiceRequest, string Hour, string Minute, string AMPM, string submit, IEnumerable<HttpPostedFileBase> file, String AssayPerformanceIssues1, IEnumerable<RunLogEntryTestExceptionDisplay> models) { } The problem is test exceptions which contains exception string and comment is comming back null.

  • .NET 2.0 Process Elevation for App Installation

    - by Brian Gillespie
    We have an application written in both C++ and .NET that installs for all users in the Program Files folder. This application downloads new versions of itself (as MSI installers) and spawns the new installer process to replace itself. The install process as it exists today: Copy an install manager app (C#, .NET 2.0) to the temp directory. Call this 'Manager' Manager is executed with elevated privs per this article. The original application exits. Manager spawns the MSI installer (with elevated privs, since the copy is elevated) Manager spawns the new version of the app. The bug: The newly installed app is running in an elevated state. This causes problems I won't enumerate here. Ideally, the launch of the newly installed app would be run with the permissions of the original user. I can't figure out how to demote the app back to being the standard user after elevation. An inelegant hack: (yeah, yeah, this whole process is inelegant anyway) Copy the install manager to the temp directory Run the install manager with standard user privs. Lets call this instance 'LowlyManager'. Original application exits. LowlyManager spawns the app again, this time with elevated privs. Let's name this instance 'UpperManagement' UpperManagement spawns the installer UpperManagement exits gracefully, returning the exit code of the installer. LowlyManager interprets the error code from UpperManagement, and spawns the newly installed application. This time as the original invoker. Is there a better way to do this? (I've left out a bunch of other details before and after these steps that make the process smoother for the user, but this should be enough to understand the core of the problem I'm trying to solve.) Other requirements: We can't install as a per-user app The user shouldn't be presented with an authentication dialog box if UAC would have simply asked "are you sure you want to allow this?". I think this might kill a solution using WindowsImpersonationContext, but I'm not sure. The system needs to work on XP, Vista, and Windows 7 (even if there is a separate process for XP).

  • Git submodules not updating?

    - by DavidYell
    I have a project in which I've included some libraries as submodules. They work fine on the machine that you add them on, but when I get home and checkout the repo, I get the folders for the submodules but they are empty. .gitmodules Neon@Neon-PC /cygdrive/c/xampp/htdocs/learning-lithium $ cat .gitmodules [submodule "libraries/lithium"] path = libraries/lithium url = git://github.com/UnionOfRAD/lithium.git [submodule "app/webroot/css/elements"] path = app/webroot/css/elements url = https://github.com/dmitryf/elements.git [submodule "app/libraries/li3_markdown"] path = app/libraries/li3_markdown url = https://github.com/sandelius/li3_markdown.git [submodule "app/webroot/markitup"] path = app/webroot/markitup url = https://github.com/markitup/1.x.git Config and status commands Neon@Neon-PC /cygdrive/c/xampp/htdocs/learning-lithium $ git submodule -af14f48b419310935446176290e1f9dc641400e0 app/libraries/li3_markdown -ebdcd8ca09c874f5e2ef81ec198cc441f37a4f74 app/webroot/css/elements -328291e49a3c7e1fb76b3342f112734864836205 app/webroot/markitup -4980010526d05c556c496ff63951da31828c5943 libraries/lithium Neon@Neon-PC /cygdrive/c/xampp/htdocs/learning-lithium $ git submodule update Neon@Neon-PC /cygdrive/c/xampp/htdocs/learning-lithium $ git submodule status -af14f48b419310935446176290e1f9dc641400e0 app/libraries/li3_markdown -ebdcd8ca09c874f5e2ef81ec198cc441f37a4f74 app/webroot/css/elements -328291e49a3c7e1fb76b3342f112734864836205 app/webroot/markitup -4980010526d05c556c496ff63951da31828c5943 libraries/lithium I added these as you would normally with, git submodule add <repo> <path> git submodule init The submodules are hosted on Github and my repo is hosted on Bitbucket, although I'm not sure if this is relevant.

  • How is conversion of float/double to int handled in printf?

    - by Sandip
    Consider this program int main() { float f = 11.22; double d = 44.55; int i,j; i = f; //cast float to int j = d; //cast double to int printf("i = %d, j = %d, f = %d, d = %d", i,j,f,d); //This prints the following: // i = 11, j = 44, f = -536870912, d = 1076261027 return 0; } Can someone explain why the casting from double/float to int works correctly in the first case, and does not work when done in printf? This program was compiled on gcc-4.1.2 on 32-bit linux machine. EDIT: Zach's answer seems logical, i.e. use of format specifiers to figure out what to pop off the stack. However then consider this follow up question: int main() { char c = 'd'; // sizeof c is 1, however sizeof character literal // 'd' is equal to sizeof(int) in ANSI C printf("lit = %c, lit = %d , c = %c, c = %d", 'd', 'd', c, c); //this prints: lit = d, lit = 100 , c = d, c = 100 //how does printf here pop off the right number of bytes even when //the size represented by format specifiers doesn't actually match //the size of the passed arguments(char(1 byte) & char_literal(4 bytes)) return 0; } How does this work?

  • [UNIX] Sort lines of massive file by number of words on line (ideally in parallel)

    - by conradlee
    I am working on a community detection algorithm for analyzing social network data from Facebook. The first task, detecting all cliques in the graph, can be done efficiently in parallel, and leaves me with an output like this: 17118 17136 17392 17064 17093 17376 17118 17136 17356 17318 12345 17118 17136 17356 17283 17007 17059 17116 Each of these lines represents a unique clique (a collection of node ids), and I want to sort these lines in descending order by the number of ids per line. In the case of the example above, here's what the output should look like: 17118 17136 17356 17318 12345 17118 17136 17356 17283 17118 17136 17392 17064 17093 17376 17007 17059 17116 (Ties---i.e., lines with the same number of ids---can be sorted arbitrarily.) What is the most efficient way of sorting these lines. Keep the following points in mind: The file I want to sort could be larger than the physical memory of the machine Most of the machines that I'm running this on have several processors, so a parallel solution would be ideal An ideal solution would just be a shell script (probably using sort), but I'm open to simple solutions in python or perl (or any language, as long as it makes the task simple) This task is in some sense very easy---I'm not just looking for any old solution, but rather for a simple and above all efficient solution

  • Application error passthru when using apache mod_proxy

    - by user303442
    Heyas. I'm using mod_proxy with apache2 provide vhost ability to multiple servlet apps running on the local machine. It works fine, for the most part. Requests come into apache then are directed to the application bound on a port on localhost. The app receives the request and responds, which is delivered back to the client by apache. The problem I'm having is that the application delivers 500's on errors, and mod_proxy stomps on them. Often these errors are caused in a ajax request and the error is handled in client side javascript. For example, a call to a server side createObject(name) might throw a NameNotUniqueException , which is delivered back as a 500. The client javascript might then display an appropriate error message. When an error is thrown by the application (resulting in a 500 response to mod_proxy), then apache stomps the error message and returns 500 Internal Server Error Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. .. the stock apache server side error message. I want mod_proxy to pass the original 500 back through to the client. Is there a directive I've missed which prevents clobbering of the 500? TIA
