• Applet problem with IPlanet and Firefox (class not found)

  - by JB Hurteaux

  I have an applet which loads nicely when accessed locally (both IE and Firefox). However, when I put my webpage in a webserver (local IPlanet), it refuses to load on Firefox (but still fine on IE). I get the following error in the java console: load: class XXX.localprinting.LocalPrintingApplet.class not found. java.lang.ClassNotFoundException: XXX.localprinting.LocalPrintingApplet.class at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.plugin2.applet.Plugin2ClassLoader.loadCode(Unknown Source) at sun.plugin2.applet.Plugin2Manager.createApplet(Unknown Source) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: java.io.IOException: open HTTP connection failed:https://XXX/test/XXX/localprinting/LocalPrintingApplet/class.class at sun.plugin2.applet.Applet2ClassLoader.getBytes(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader.access$000(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) ... 7 more Exception: java.lang.ClassNotFoundException: XXX.localprinting.LocalPrintingApplet.class Any idea what could explain the different behavior in the webserver? I researched the issue of "class not found" already but without finding something relevant.

• Form Inheritance in Visual Studios designer implementations

  - by CooPzZ

  I'm in the process of Moving a project from Visual Studio 2003 to 2005 and have just seen the The event Click is read-only and cannot be changed when using inherited forms regardless of the Modifier on the Base Forms Controls will make all the Controls from the Base Readonly in the designer (Though in 2003 it didn't work this way). I found this post metioning that this functionality has been temporarily" disabled http://social.msdn.microsoft.com/Forums/en-US/winformsdesigner/thread/c25cec28-67a5-4e30-bb2d-9f8dbd41eb3a Can anyone confirm whether this feature is used anymore? or how to program around it to be able to use the Base Control Events and still have a designer? This is one way I've found but quite painfull when it used to do the plumbing for you. even just hiding one of the controls you have manually do now. Public Class BFormChild Friend Overrides Sub cmdApply_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdApply_Click(sender, e) End Sub Friend Overrides Sub cmdCancel_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdCancel_Click(sender, e) End Sub Friend Overrides Sub cmdOk_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdOk_Click(sender, e) End Sub End Class

• fubar'd a ruby installation on ubuntu, need helping purging it for reinstall

  - by tipu

  i originally followed these steps to get a RoR environmentgoing: https://help.ubuntu.com/community/RubyOnRails that worked. then i put 1.9.2 on here. then i decided i want the original setup, did a "whereis ruby" and deleted those directories manually. that fubar'd my ruby installation. i can't use the repository to what i originally had. how can i purge ruby from completely and start fresh? right now the specific error is this: /usr/lib/ruby/1.8/rubygems.rb:11:in `require': no such file to load -- thread (LoadError) from /usr/lib/ruby/1.8/rubygems.rb:11 from /usr/bin/gem1.8:8:in `require' from /usr/bin/gem1.8:8 tipu@tipu_ubuntu:~$

• Ruby: Read large data from stdout and stderr of an external process on Windows

  - by BinaryMuse

  Greetings, all, I need to run a potentially long-running process from Ruby on Windows and subsequently capture and parse the data from the external process's standard output and error. A large amount of data can be sent to each, but I am only necessarily interested in one line at a time (not capturing and storing the whole of the output). After a bit of research, I found that the Open3 class would take care of executing the process and giving me IO objects connected to the process's standard output and error (via popen3). Open3.popen3("external-program.bat") do |stdin, out, err, thread| # Step3.profit() ? end However, I'm not sure how to continually read from both streams without blocking the program. Since calling IO#readlines on out or err when a lot of data has been sent results in a memory allocation error, I'm trying to continuously check both streams for available input, but not having much luck with any of my implementations. Thanks in advance for any advice!

• The whole site is blocked while one page is waiting for blocking operation (PHP, ASP.NET). Why?

  - by artvolk

  Good day! I've found interesting behaviour for both LAMP stack and ASP.NET. The scenario: There is page performing task in 2-3 minutes (making HttpWebRequest for ASP.NET and curl for PHP). While this page is processed all other requests to this virtual host from the same browser are not processed (even if I use different browsers from one machine). I use two pages written in PHP and C#. I've tested with Apache+PHP in both mod_php and fast_cgi modes on Windows and Debian. For ASP.NET I use IIS6 (with dedicated app pool for this site and with default app pool) and IIS7 in integrated mode. I know that it is better to use async calls for such things, but I'm just curious why single page blocks the entire site and not only the thread processing the request? Thanks in advance!

• BufferedImage Help

  - by Eddy Freeman

  I posted a question in sun java forums sometime ago and i am finding it hard to understand the first response i received from the replier though it seems he gave me the correct approach to my problem. The link to the question is: http://forums.sun.com/thread.jspa?threadID=5436562&tstart=0 Someone replied that i should use BufferedImage and make tiles. I don't really understand what the tiles mean in connection with the BufferedImage. I would like someone to explain to me what the tiles are and how they are created in the BufferedImage. I have searched the web for a while but couldn't find any link that can help me understanding the basics of the tiles and creating the tiles. Any pointer to a site is also appreciated. I need help in understanding the tiles in connection with the BufferedImage and also how they are created.

• Storage for large gridded datasets

  - by nullglob

  I am looking for a good storage format for large, gridded datasets. The application is meteorology, and we would prefer a format that is common within this field (to help exchange data with others). I don't need to deal with special data structures, and there should be a Fortran API. I am currently considering HDF5, GRIB2 and NetCDF4. How do these formats compare in terms of data compression? What are their main limitations? How steep is the learning curve? Are there any other storage formats worth investigating? I have not found a great deal of material outlining the differences and pros/cons of these formats (there is one relevant SO thread, and a presentation comparing GRIB and NetCDF).

• Clojure load files

  - by Nate

  I'm trying to set up a simple clojure project, and I'm not sure how to load files between the project. I'm sure that the answer is in the documentation, but I can't find a simple answer any where and I'm not sure where to look. Essentially, my directory looks like this: Clojure/ clojure/ clojure.jar other clojure files clojure-contrib/ clojure-contrib.jar other contrib files project/ main.clj utils.clj And I want main.clj to be something like this: (ns project.main (:require project.utils)) (greet) and utils.clj to be something like this: (ns project.utils) (defn greet [] (println "Hello, World!")) But that fails with: Exception in thread "main" java.io.FileNotFoundException: Could not locate project/utils__init.class or project/utils.clj on classpath: (main.clj:1) When I attempt to run it. How do you set up a simple clojure project?

• Temporary files & folders on Windows

  - by GRIGORE-TURBODISEL

  Emulating multithreading by loading a DLL multiple times (it's designed for this). Since LoadLibrary() doesn't really allow it, the DLL copies itself into a temporary file, via GetTempPath() and GetTempFileName(). It's a small file and upon thread destruction it frees the library and deletes the temporary file. Problem now is that the number of threads is configurable (maniacs can pick 50, 100, more) which basically exposes the risk of running unstable, crash and not go through the usual "delete temporary files" routine. Is it okay if I just leave those temporary files to die there? Does the OS usually clean the up by itself? Or should I write an autocleanup routine? If yes, how can I go about saving another temporary file to hold a list with those files, and not hit UAC restrictions or otherwise? Any ideas?

• Extending ClaimsIdentity in MVC3

  I've got my claims set-up with MVC3 using azure and everything is going well. What I need to do now is extend the Claims Identity that's in the current thread / http context and add my own information (DOB, Address.. that sort of stuff) so my question is - where is the best place to do this? any examples would be great.. I presume that when the user is authenticated id then have to go to the DB and pull back the relevant record for the user then add it to the custom Claims Identity object? cheers. ste.

• Linenumber for Exception thrown in runtime-compiled DotNET code

  - by David Rutten

  Not quite the same as this thread, but pretty close. My program allows people to enter some VB or C# code which gets compiled, loaded and executed at runtime. My CompilerParams are: CompilerParameters params = new CompilerParameters(); params.GenerateExecutable = false; params.GenerateInMemory = true; params.IncludeDebugInformation = false; params.TreatWarningsAsErrors = false; params.WarningLevel = 4; When this code throws an exception I'd like to be able to display a message box that helps users debug their code. The exception message is easy, but the line-number is where I got stuck. I suspect that in order to get at the line number, I may need to drastically change the CompilerParameters and perhaps even the way these dlls get stored/loaded. Does anyone know the least steps needed to get this to work?

• Facebook javascript in address bar, possible to replicate?

  - by DoMx

  This is my first experience with stackoverflow and I'm afraid my question asks of a lot for a first. I was looking at this thread: http://stackoverflow.com/questions/2634159/javascrypt-in-the-adress-bar-is-this-malicious and as you will see SLaks has very kindly deobfuscated the javascript and left us with what appears as the Javascript behind the automatic facebook invite code. As I'm fairly new to javascript, I was wondering, what other components were needed to get this code to work? You of course have the functions there and they are called by the obfuscated javascript but how exactly? Would it be possible to replicate this on a page of my own using the information available or is there more to this script I am missing? I am willing to financially assist somebody who could compile a solution for me. Thank you in advance.

• Windows 7 losing one of my displays after restart

  - by j_kubik

  I have an Intel DZ68BC motherboard with Intel HD graphics card using two monitors (on DVI and on HDMI » VGA). My friend asked me to test if his NVIDIA graphics card works well on my computer (at his it was doing some trouble), so I inserted it in my computer, installed the NVIDIA driver and it worked quite well. Then I removed it, uninstalled everything NVIDIA-related I could find and switched monitors back to my Intel card. Since then after every system start/restart, the system sees only monitor on HDMI » VGA connector, completely ignoring the DVI monitor. I noticed that installing the Intel video drivers causes the system to recognize the second monitor if I don't immediately reboot. After a reboot, the system recognizes only the HDMI » VGA monitor. I also tried starting in safe-mode and using DriveSweeper to remove the remains of NVIDIA drivers. While it seems that some drivers were removed, the situation didn't change. Now I am out of ideas and I really wouldn't like to reinstall the system (again...). I also tried restoring the system to the state before this whole story, but it also didn't change anything. EDIT: I am still trying to troubleshoot this problem. The only point that I could start was driver re-instalation. I traced down the part that restores right settings to a call: C:\Users\Jarek\Desktop\GFX_Win7_64_8.15.10.2696\x64\Drv64.exe -driverinf "C:\Users\Jarek\Desktop\GFX_Win7_64_8.15.10.2696\Graphics\igdlh64.inf" -flags 20 -keypath "Software\Intel\Difx64" This call fixes my displays, and as workaround, I will add it for now to my autorun. I am still looking for better solution anyway... EDIT2: Using DriverView i made a list of currently used drivers both before and after fixing my display using above command. Then i compared logs: No drivers were removed by fixing command. Drivers added by fixing command: MS Remote Access serial network driver (asyncmac.sys) security processor (spsys.sys) Drivers that changed base address (indicates driver-reload?) Canonical Display Driver (cdd.dll) Intel Graphics Kernel Mode Driver (igdkmd64.sys) Monitor Driver (monitor.sys) Added drivers seem rather unrelated to the problem to me, reloaded drivers are just a cnsequence of installing new driver file so there is not much to go here... I really cannot make heads or tails out of it...

• compile error: The import xxxx cannot be resolved

  I am developing a Java project using Eclipse. The project uses another project called engine, which I have added in my project build-path. As I need to call a dabo class, called House, in one of my project class, named Window, I have used the following code as usual: import ee.asus.kernel.House; I got however the following error in compiling time: Exception in thread "main" java.lang.Error: Unresolved compilation problems: The import ee cannot be resolved House cannot be resolved to a type House cannot be resolved to a type House cannot be resolved to a type at main.ee.asus.GUI.FrameWindow.Window.<init>(Window.java:10) at main.ee.asus.GUI.StartApplication.main(StartApplication.java:13) It's worth to point out that my prject and the dabo project use the same directory/packages names. Does anyone have a clue where the error may be?

• How do I trigger specific parts of a storyboard in WPF?

  - by George

  I have several grids in my window. I have created a storyboard that moves them left by x pixels when a button is clicked. I want to make it so that when the button is clicked again those grids move another x pixels, however I'm unable to find out how to do this as it's not a common task on tutorials. I have tried creating a second storyboard to do this, however that won't work as then the grids will be back at their starting positions. One solution might be to create a third set of keyframes after the first two sets, and somehow pause the animation when it gets there, and resumes it again when the button is clicked, however I'm not sure how to pause a storyboard when it reaches a keyframe. This would also make reversing the grids difficult (using this approach http://social.msdn.microsoft.com/forums/en-US/wpf/thread/ac54de71-f750-4940-91a2-231810308727/), as I'd like to make another button make the grids go the other way.

• List replies in a winform

  - by andrew

  In my C# app I get an xml from a server that contains some replies like in a forum thread (with elements like author, time, body, title, whatever). When I get this xml, I create a new form in which i want to display these replies, and a little text box with an "add reply" button. I'd also like some edit buttons on perhaps my own replies in the reply list displayed in the form. The simplest way that came to my mind to display the replies is to put a web browser control in the form, generate a full html page in a string from the xml, and throw it in that web browser control. And under it i can put the text box with the add reply button. Everything is ok, except that i have no idea of how i could implement the edit function on my own replies (i mean i could add a link in there... but link to what) I would like to know if there is a way to get that edit event from the web browser control (my guess is i can't) or another (maybe simple/easy) idea of displaying the replies in a winform using other controls

• Network Services disabled (not starting) on Windows XP

  - by Rickesh John

  I am currently running Windows XP Service Pack 3 on my system. But today, when I failed to connect to the internet, via a LAN cable, I realized that almost all of the vital network services had stopped functioning. Any attempts to start it through services.msc gives me the following message: Could not start the DNS Client Service on Local Computer Error 1068: The dependency service group failed to start All my software or services that are related to networking have stopped functioning, for example, Windows Firewall is turned off permanently, so is my Avast Anti-Virus' service of Real Time Shields and Web Shield. When I insert the LAN wire into my laptop, it registers itself, but this is what I get when I do a ping localhost C:>ping localhost Unable to contact IP driver, error code 2 Moveover, with ipconfig I get this : Windows IP Configuration An internal error occurred: The request is not supported. Please contact Microsoft Product Support Services for further help. Additional Information: Unable to query host name On some further poking around, I saw that none of the "NETWORK SERVICE" process in task manager, except svchost.exe were running. Also, when I first opened the task manager, I saw some 20 processes running with username column empty for most of them. With some search in Google, I found out that these services were important, DHCP DNS Net logon Network connection Network location Awareness TCP/IP Net BIOS Helper none of them, except Network Connections are working, they do not start. The event viewer of my system shows a bunch of 7000 and 7001 event errors. I have tried re installing the network driver, booting in safe mode with networking and tried to enable those services mentioned above. I had disabled System Restore some time back, so I have no restore points for my system. I tried a lot of things from Google searches but none of them worked. Also, with such a long list of issue, I am a little confused as to what should I search on the internet. :( One more thing I would like to mention, previous morning, my anti-virus Avast detected a RootKit buried deep in my system folders. It was removed, but maybe this was a problem caused by the root kit. I did run a boot-time scan but no viruses were found. Please please please advice. Is formatting and re-installation of Windows my only option?

• Windows 8 disk errors

  - by wrongusername

  So yesterday, I forcibly restarted my Windows 8 PC. VMWare Workstation was having some trouble with the guest Linux Mint OS. It wasn't responding for some time, so I tried suspending it September 28th or perhaps even before. It wouldn't suspend -- I forgot what the window looked like, but all options in the power menu were disabled (i.e. "Shutdown," "Power Off," and options like that were all disabled). I eventually killed the VMWare application through Task Manager, though I was too lazy to hunt down the running virtual machine itself, and decided to kill it by just shutting down my PC entirely. The PC wouldn't shut down for quite some time after the monitor went blank, so I did a cold reset by holding the power button. I then powered it on again and Windows briefly gave me some message like "Search for KERNEL_STACK_INPAGE_ERROR." Windows then started diagnosing some problems and gave me the message, "Repairing disk errors. This might take over an hour to complete." That was yesterday night, and I went to sleep without waiting for it to finish. This morning, it said that the repair failed, and that the log was at C:\windows\system32\LogFiles\srt\srtTrail.txt (as I remember it -- I don't have the exact path I wrote down right now). It gave me some other options to troubleshoot, such as resetting Windows (files and settings still intact, but programs not installed through the app store will be erased). That didn't work (no error message given, I was just told it didn't work). I tried rebooting in safe mode, the same diagnosis process begins, except that this time it doesn't bother with the automatic repairs again. So I tried using the command prompt to try to see if my files are at least still there. I was on the X drive, and I couldn't cd to the C drive. I couldn't find my folder under Users (of course?), and couldn't find the srt folder under LogFiles either. I am not sure what to try next. I have backed up everything, but to the cloud, so if absolutely necessary I can start off with a fresh copy of Windows and restore all my data, though it would be a hassle. Any thoughts on what might be wrong or what I can try? My computer was purchased just this June, so the hard drive should still be pretty new.

• create a folder and files in c:\program files\myApp\data in windows 7

  - by ile

  I have an old c++ application that needs to be modified to work with windows 7. Problem is in creating a new folder and saving a file in that folder. This folder should be created in c:\program files\myApp\data\newFolder. This is function I use to create new folder and get errors: if(!CreateDirectory(pathSamples,NULL)) //Throw Error { DWORD errorcode = GetLastError(); LPVOID lpMsgBuf; FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_IGNORE_INSERTS, NULL, errorcode, MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), (LPTSTR)&lpMsgBuf, 0, NULL ); MessageBox(NULL, (LPCTSTR)lpMsgBuf, TEXT("Error"), MB_OK); } In XP this works, but in Windows 7 it doesn't. If I run application as administrator than the folder is created, otherwise "Access is denied" error is thrown. My question is following: Is there an option to make changes to the code so that the folder can be created in "program files" nad that files can be saved in this folder? PS I saw this thread already but it doesn't answer my question. Thanks, Ilija

• Will PHP Die In Web Page Development World?

  - by Morgan Cheng

  I know that PHP is still the most popular web programming language in the world. This question just want to bring some of my concerns about PHP. PHP is naturally bound to C10K problem. Since PHP (generally run in Apache) cannot be event-driven or asynchronous, each HTTP request will occupy at least one thread or process. This makes it resistant to be more scalable. Currently, a lot of web sites (like Facebook) with high performance and scalability still depends on PHP in their front end servers. I suppose it is due to legacy reason. Is it possible that PHP will be replaced by language more suitable for C10K?

• Ridiculously Simple Erlang Question

  - by Aiden Bell

  Read (skimmed enough to get coding) through Erlang Programming and Programming Erlang. One question, which is as simple as it sounds: If you have a process Pid1 on machine m1 and a billion million messages are sent to Pid1, are messages handled in parallel by that process (I get the impression no) and is there any guarantee of order when processing messages? ie. Received in order sent? Coming from the whole C/Thread pools/Shared State background ... I want to get this concrete. I understand distributing an application, but want to ensure the 'raw bones' are what I expect before building processes and distributing workload. Also, am I right in thinking the whole world is currently flicking through Erlang texts ;)

  so i'm about to start a new website from scratch and i've spent about a week trying to figure out what technology to go with. i'm sold on ASP NET MVC. i'm 100% sure i'm going to love using that. but what i am not so sure about yet is using LINQ 2 SQL. so far i've gathered some data... 1) stack overflow uses it - can't be that bad 2) can be REALLY slow if you don't take advantage of compiled queries 3) will always be slower than ADO net, but can be almost just as fast if using #2 in the proper places 4) is NOT the preferred MS solution (there was a thread here on SO about dropping support) i'm itching to use it, but just want to make sure it's the best for me. i come from a heavy ADO/stored procedure and traditional asp net background (this will be my first experience with ASP MVC).
