  • Hard Disk Not Counting Reallocated Sectors

    - by MetaNova
    I have a drive that is reporting that the current pending sectors is "45". I have used badblocks to identify the sectors and I have been trying to write zeros to them with dd. From what I understand, when I attempt writing data directly to the bad sectors, it should trigger a reallocation, reducing current pending sectors by one and increasing the reallocated sector count. However, on this disk both Reallocated_Sector_Ct and Reallocated_Event_Count raw values are 0, and dd fails with I/O errors when I attempt to write zeros to the bad sectors. dd works fine, however, when I write to a good sector. # dd if=/dev/zero of=/dev/sdb bs=512 count=1 seek=217152 dd: error writing ‘/dev/sdb’: Input/output error Does this mean that my drive, in some way, has no spare sectors to be used for reallocation? Is my drive just in general a terrible person? (The drive isn't actually mine, I'm helping a friend out. They might have just gotten a cheap drive or something.) In case it is relevant, here is the output of smartctl -i : Model Family: Western Digital Caviar Green (AF) Device Model: WDC WD15EARS-00Z5B1 Serial Number: WD-WMAVU3027748 LU WWN Device Id: 5 0014ee 25998d213 Firmware Version: 80.00A80 User Capacity: 1,500,301,910,016 bytes [1.50 TB] Sector Size: 512 bytes logical/physical Device is: In smartctl database [for details use: -P show] ATA Version is: ATA8-ACS (minor revision not indicated) SATA Version is: SATA 2.6, 3.0 Gb/s Local Time is: Fri Oct 18 17:47:29 2013 CDT SMART support is: Available - device has SMART capability. SMART support is: Enabled UPDATE: I have run shred on the disk, which has caused Current_Pending_Sector to go to zero. However, Reallocated_Sector_Ct and Reallocated_Event_Count are still zero, and dd is now able to write data to the sectors it was previously unable to. This leads me with several other questions: Why aren't the reallocations being recored by the disk? I'm assuming the reallocation took place as I can now write data directly to the sector and couldn't before. Why did shred cause reallocation and not dd? Does the fact that shred writes random data instead of just zeros make a difference?

  • How can I avoid permission denied errors when attempting to deploy a rails app with capistrano?

    - by joshee
    Total noob here. I'm attempting to deploy an app through Capistrano. I'm getting relentless permission denied errors when I attempt to run cap deploy:update. Seemingly at least some of these errors are due to missing directories that trigger a "Permission Denied" error. (I'm doing setup on root just temporarily.) set :user, 'root' set :domain, 'domainname.com' set :application, 'appname' # adjust if you are using RVM, remove if you are not $:.unshift(File.expand_path('./lib', ENV['rvm_path'])) require "rvm/capistrano" set :rvm_ruby_string, '1.9.2' # file paths set :repository, "ssh://[email protected]/~/git/appname.git" set :deploy_to, "/var/rails/appname" # distribute your applications across servers (the instructions below put them # all on the same server, defined above as 'domain', adjust as necessary) role :app, domain role :web, domain role :db, domain, :primary => true set :deploy_via, :remote_cache set :scm, 'git' set :branch, 'master' set :scm_verbose, true set :use_sudo, false set :rails_env, :production namespace :deploy do desc "cause Passenger to initiate a restart" task :restart do run "touch #{current_path}/tmp/restart.txt" end desc "reload the database with seed data" task :seed do run "cd #{current_path}; rake db:seed RAILS_ENV=#{rails_env}" end end after "deploy:update_code", :bundle_install desc "install the necessary prerequisites" task :bundle_install, :roles => :app do run "cd #{release_path} && bundle install" end Here's my result: ** [domainname.com :: out] Cloning into '/var/rails/appname/shared/cached-copy'... ** [domainname.com :: err] Permission denied, please try again. ** [domainname.com :: err] Permission denied, please try again. ** [domainname.com :: err] Permission denied (publickey,gssapi-with-mic,password). ** [domainname.com :: err] fatal: The remote end hung up unexpectedly I'm able to ssh without a password, so not sure about that publickey error.

  • Windows 7 sharing folder from command line, selecting users and triggering the "Apply" of changes

    - by clintp
    I have a drive that doesn't get mounted until after I log in. (A Truecrypt thumbdrive device, and no, I'm not making it a "System Favorite" to get around this.) I'd like to construct a batch file to share it once I've gotten it mounted because the sharing info doesn't seem to stick through a reboot. From the GUI, I'd go into the folder Properties-Sharing. And then in Advanced Sharing I'd pick the name to share it as. And then under the "Share..." button I'd pick the users and the permissions I want to grant them. After "Apply" there's a pause -- I'm not sure what's happening here, but the dialog says "Sharing Items..." -- and then everything is okay. From the command line, I've done: net share MyFolder=F:\MyFolder cacls F:\MyFolder /G FirstUser:F cacls F:\MyFolder /G OtherUser:F And this almost works. I can see the share on the network then, but nobody has permissions to do anything. If I go into the GUI and change anything (and I can see my command-line changes in there already) and press "Apply" I get the: "Sharing Items.... This may take a few minutes" Dialog... and then Voila! It works. I get the "Your folder is shared" dialog with the command-line changes I made, along with the GUI change that I made to trigger the "Sharing Items..." dialog. Everything's peachy. Is a service being restarted? Which one? What's triggering the sharing to take effect? And -- more importantly -- how do I do it from the command line?

  • What does opening a serial port do?

    - by reve_etrange
    What does opening the standard PC serial port do, in electrical terms (i.e. what voltages on which pins)? For example, the ancient VB6 program which controls an apparatus I am tasked with maintaining toggles .PortOpen to control some TTL. The connection only used 2 pins (bad solders fell apart), so which pins do I solder to? The only labels / documentation refer to pins 7 and 9, saying 0V and 5V parenthetically, but does .PortOpen really just put 5V between RI and RTS?. As a post script, this isn't the weirdest thing about the set up. The TTL I referred to above also connects to an instrument via a BNC to DB9 (!), with only 1 pin used. I guess there was an assumption about a common ground, since the BNC shielding isn't connected to the GND pin? The connection is to the instrument's 'foot pedal' pin, it was a way to remotely trigger the device. Update According to this page, the DTR and RTS pins can go high when the port is opened. If they were so configured, they will subsequently go low when the port is closed. If DTR and RTS are not enabled, opening the port should set both to low (and keep them low).

  • Problem with ubuntu 10.10 running from USB drive

    - by Surjya Narayana Padhi
    Hi Geeks, I recently downloaded Ubuntu 10.10 and created an USB drive with that. I started to run the Ubuntu from that USB drive. But I am facing so much problem. I am thinking why its not so much easy like Windows to do all my job in ubuntu. Always I get some error message or to install something. This time I am getting the following errors. I am trying to download and install Aircrack-ng. So used the command sudo apt-get install aircrack-ng. But the installation stops with the following error : update-initramfs: deferring update (trigger activated) cp: cannot stat `/vmlinuz': No such file or directory dpkg: error processing bcmwl-kernel-source (--configure): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: initramfs-tools bcmwl-kernel-source E: Sub-process /usr/bin/dpkg returned an error code (1) I don't even have the aptitude command installed till now. Are all these errors because of I am running the ubuntu from USB drive? Is there any simple and easy way to go to Ubuntu Software Center and download all the required essentials at one shot and then Aircrack-ng? I could not find the Aircrack-ng in Ubuntu Software Center Can anybody give me detail steps to solve all my problems above. I am frustrated searching for updates and installations. When something works and something does not work. Can anybody suggest me how I should proceed after installing ubuntu to run on a USB drive. So that I can use the OS like Windows. Like software download,wireless driver, sound, video, documents, C:, D: all things should be there. Please somebody help.

  • How to scan multiple pages from a book under Linux?

    - by rumtscho
    I want the process to look like: I choose the correct scan settings (dpi, color depth, etc) I lay the first page on the scanner and trigger the process The scanner scans the page and waits for me to position the next page correctly I confirm that the next page is ready for scanning Repeat the above two steps until I tell the scanner that there are no more pages to come The scanner saves everything into a single PDF. I tried both xsane and gscan2pdf. First problem: they want me to know how many pages will be scanned. This is already a nuisance, but I can do the counting if needed. The main problem is that in step 3, the scanner does not pause. It is probably optimised for being fed loose sheets. The next scan process is triggered automatically as soon as the CCD has returned to the start position. The time the scanner needs to return the CCD is very short and I can't turn the page and position the book properly. Is there a software which can do the scan process in the way I described above, or did I just miss a setting available in xsane or gscan2pdf to make the scanner pause? If it makes any difference, the scanner is an Epson Stylus SX620FW, I run it using the manufacturer-provided driver.

  • VMWare use of Gratuitous ARP REPLY

    - by trs80
    I have an ESXi cluster that hosts several Windows Server VMs and around 30 Windows workstation VMs. Packet captures show a high number of ARP replies of the form: -sender_ip: VM IP -sender_mac: VM virtual MAC -target_ip: 0.0.0.0 -target_mac: Switch interface MAC The specific addresses aren't really a concern -- they're all legitimate and we're not having any problems with communications (most of the questions surrounding GARP and VMWare have to do with ping issues, a problem we don't have). I'm looking for an explanation of the traffic pattern in an environment that functions as expected. So the question is why would I see a high number of unsolicited ARP replies? Is this a mechanism VMWare uses for some purpose? What is it? Is there an alternative? EDIT: Quick diagram: [esxi]--[switch vlan]--[inline IDS]--[fw]--(rest of network) The IDS is complaining about these unsolicited ARPs. Several IDS vendors trigger on ARP replies without a prior request, or for ARP replies that have a target IP of 0.0.0.0. The target MAC in these replies is the VLAN interface on the switch. Capture points: -The IDS grabs the offending packets -The FW can see the same ones -A VM on the ESXi host does not see these, although there is an ARP request for a specific IP on the ESXi host that has source_ip=0.0.0.0 and source_mac=[switch vlan interface]. I can't share the captures, unfortunately. Really I'm interested in finding out if this is normal for an ESXi deployment.

  • Microsoft Word "Random" Crashes

    - by Bent Rasmussen
    Word seemingly randomly crashes in an application setting where it is first being used to programmatically databind (bookmarks) and then directly afterwards opened on the user machine for further user input. The error message is quite precise but the workaround has eluded me. Word crashes a moment or two after it has been opened on the user machine with the below exception details. Problem signature: Problem Event Name: APPCRASH Application Name: WINWORD.EXE Application Version: 14.0.6129.5000 Application Timestamp: 5082f354 Fault Module Name: wwlib.dll Fault Module Version: 14.0.6129.5000 Fault Module Timestamp: 5082f3dc Exception Code: c0000005 Exception Offset: 000eed32 OS Version: 6.1.7601.2.1.0.16.7 Locale ID: 1030 Additional information about the problem: LCID: 1030 skulcid: 1030 Sometimes one can run the exact same scenario 50 times before experiencing a crash, other times only a few times. We have tried using different versions of the Word format as well as renaming the databound file after saving so that the file being opened on the user machine is different. Principally Word should never crash but perhaps there is some workaround that can make Word not crash. Googling for a solution there appears to be multiple things that can trigger this bug.

  • Computer randomly shuts itself off

    - by Decency
    I have not been able to determine a pattern for why this happens, despite my best efforts. I've attempted to run it on full power with Prime95 and this doesn't trigger a restart. Generally the restarts occur while I'm playing games, watching videos, or even just having multiple tabs open in a browser. However, I often play processor intense games for hours without any restarts occurring, and sometimes they'll happen 3-4 times in an hour during less intense activity, so I don't think that is the problem. I imagine it has something to do with overheating or power consumption so I've been monitoring CPU temperature and cleaning with compressed air, but the problem keeps happening. I don't know how to track power consumption, and assume that this is the problem. Whenever this occurs, the sound gets stuck in a short loop of whatever was playing at the time, though restarts also occur when nothing is playing. Here is a screenshot of temperatures: and under load: Here's the parts list: http://secure.newegg.com/WishList/PublicWishDetail.aspx?WishListNumber=10546754 As shown in the list, the case includes a 585W Power Supply, which I've been told should be plenty. I built the computer myself with a friend's guidance but it's very possible I did something wrong. Right now I'm looking into ensuring that I have the latest drivers for all components. Any help would be appreciated- thanks.

  • USB Device Not Recognized (Mac)

    - by Nargis
    Fortunately, my Mac-pro also made one of my USB storage devices inoperable. My data loss in that USB device but such as another USB device and USB keyboard are unaffected. I have heard that my friend usually trigger this problem by having at least two devices plugged in - typically thumb drives/USB flash drives, and then once a second flash drive is plugged in that become unrecognized. I have only two USB ports and first I think port loose when I connect two USB devices. But later I found these hidden files (“.Spotlight-V100”, “.TemporaryItems”, “.Trashes”, and “._.Trashes”) are created by Mac OS. And before unrecognized that USB device I have deleted these files and my friend had also done the same action. Now I don’t want to test for next USB device to become unrecognized and I won’t deleted any hidden system file inside the flash drives. But I really want to know why these problems happened. Can I delete these hidden files when I only connect to virtual machine (Vista), because I used to delete all useless hidden files from USB flash drives? Any suggestions or thoughts to prevent this or alternative suggestions to fix the problem that take lossless would be much appreciated.

  • Cannot terminate process, "already terminated"

    - by felix-freiberger
    On Windows 8, I regularly get processes into a state where I can't terminate them. Skypekit.exe seems to be the process that's most likely to trigger that issue, but other processes can do that, too. When I try to terminate these processes, I sometimes get an "access denied" message, sometimes nothing happens - but every following attempt to kill that process results in an "access denied" message, too, even though I... have administrative rights (and ran the task manager with it) own that process have the right to terminate it "Process Hacker 2" shows a more detailed error message, stating that I couldn't terminate the process because it already is terminated. Still, the process is most definitely still there, because every task manager I tested still can see it. Process Hacker's "Terminator" is unable to kill such a process, but when running the "Close the process' handles" tactic, Process Hacker gets stuck himself, leaving its windows in "not responding". In that state, other task managers are in turn unable to kill Process Hacker. The only way I found to actually end these processes is to shutdown (which works without any problems). Why is this happening? How can I kill these processes?

  • Vim autocommand on BufDelete prevents opening help window

    - by Kyle Strand
    I have the autocommand described here in my .vimrc: http://superuser.com/a/669463/199803 EDIT: Copied into body of question for convenience: function CountListedBuffers() let cnt = 0 for nr in range(1,bufnr("$")) if buflisted(nr) && ! empty(bufname(nr)) let cnt += 1 endif endfor return cnt endfunction function QuitIfLastBuffer() if CountListedBuffers() == 1 :q endif endfunction autocmd BufDelete * :call QuitIfLastBuffer() Bizarrely, though, it seems that if I have exactly one listed buffer, and I try to use the :help command, the help window fails to open (or perhaps opens and is immediately closed). If I comment out that autocommand line in my .vimrc, this behavior no longer occurs. Why is this happening, and how can I fix it? Why would :h even trigger the BufDelete event? EDIT: setting verbosity to level 12, I can see that the BufDelete event is indeed occurring. Here's the portion of the output that looks relevant to me: Executing BufAdd Auto commands for "*" autocommand call <SID>BMAdd() calling function <SNR>6_BMAdd calling function <SNR>6_BMAdd..<SNR>6_BMFilename calling function <SNR>6_BMAdd..<SNR>6_BMFilename..<SNR>6_BMMunge calling function <SNR>6_BMAdd..<SNR>6_BMFilename..<SNR>6_BMMunge..<SNR>6_BMTruncName function <SNR>6_BMAdd..<SNR>6_BMFilename..<SNR>6_BMMunge..<SNR>6_BMTruncName returning '/usr/local/share/vim/vim74/doc' continuing in function <SNR>6_BMAdd..<SNR>6_BMFilename..<SNR>6_BMMunge function <SNR>6_BMAdd..<SNR>6_BMFilename..<SNR>6_BMMunge returning 'help\.txt\ (4)\^I/usr/local/share/vim/vim74/doc' continuing in function <SNR>6_BMAdd..<SNR>6_BMFilename calling function <SNR>6_BMAdd..<SNR>6_BMFilename..<SNR>6_BMHash function <SNR>6_BMAdd..<SNR>6_BMFilename..<SNR>6_BMHash returning #340582286 continuing in function <SNR>6_BMAdd..<SNR>6_BMFilename function <SNR>6_BMAdd..<SNR>6_BMFilename returning #0 continuing in function <SNR>6_BMAdd function <SNR>6_BMAdd returning #0 continuing in BufAdd Auto commands for "*" Executing BufDelete Auto commands for "*" autocommand :call QuitIfLastBuffer()

  • is there a way to run a command before puppet implements a change?

    - by Patrick
    I want to have puppet run a specific command before performing any type of change. I am aware of the prerun_command option in the main puppet.conf, but this is not what I'm looking for. I want the command to only run if something is about to change, not on every puppet run. Here's the scenario. Let's say I have a bunch of web servers behind a load balancer. I then want puppet to update the web site files. But in order to prevent issues where some files have been updated, but other files haven't, and the mixed versions causing problems, I want to take the server out of the load balancer pool. I could write a script which when run will tell the load balancer to remove the box from the pool. Then puppet can do the change, and use postrun_command to put the box back in the pool once complete. But I need a way to run that script to remove the server from the pool. The only solution I can think of is to keep 2 copies of the files on the box. One a staging copy, and when puppet updates that, use a notify action to trigger the removal script, and then copy from staging into the live location. But I was hoping for something a little more generic that would work on any change being performed (upgrading a package, restarting a service, creating a user, anything).

  • Nginx conditional not evaluating correctly

    - by cjc
    I'm running into a weird problem with nginx and how it evaluates conditionals. Here's the relevant configuration: set $cors FALSE; if ($http_origin ~* (http://example.com|http://dev.example.com:8000|http://dev2.example.com)) { set $cors TRUE; } if ($request_method = 'OPTIONS') { set $cors $cors$request_method; } if ($cors = 'TRUE') { add_header 'Access-Test' "$cors"; add_header 'Access-Control-Allow-Origin' "$http_origin"; add_header 'Access-Control-Allow-Methods' 'POST, OPTIONS'; add_header 'Access-Control-Max-Age' '1728000'; } if ($cors = 'TRUEOPTIONS') { add_header 'Access-Test' "$cors"; add_header 'Access-Control-Allow-Origin' "$http_origin"; add_header 'Access-Control-Allow-Methods' 'POST, OPTIONS'; add_header 'Access-Control-Allow-Headers' 'X-Requested-With, X-Prototype-Version'; add_header 'Access-Control-Max-Age' '1728000'; add_header 'Content-Type' 'text/plain'; } So, the conditional blocks never trigger. When I remove the conditions, I see that the "Access-Test" header and the "Access-Control-Allow-Origin" set correctly, but, as noted, enabling the conditionals causes the headers not to be sent. I'm testing by running: curl -Iv -i --request "OPTIONS" -H "Origin: http://example.com" http://staging.example.com/ Am I missing something obvious? I've tried the "if" with and without quotes, etc. This is nginx 1.2.9.

  • Apache on CentOS 5.9 VM serves my optimized images corrupted (but my Mac doesn't)

    - by Robert K
    I'm using a Vagrant VM to mirror the client's environment as closely as I can. As part of our build process we do no optimization of assets early on; that comes as we're ready to take a site live. Needless to say, this issue is beginning to worry me as we need to take the site live very soon. I use ImageOptim to automate optimization of image assets, which runs a whole series of tools (Zopfli, PNGOUT, OptiPNG, AdvPNG, PNGCrush). I always set the optimizations to their maximum setting. After optimization, my PNGs start looking like this: What's weird is, if I serve the same file through my Mac's copy of Apache, not through Vagrant, the image loads fine. In fact, the only time it's ever corrupt like this is when the image is served from the Vagrant VM and its install of Drupal. All optimized JPEGs display only the first ~20% of the image. And PNGs, depending on the image, may show either a portion or the "progressive"-style corruption below. The browser itself makes no difference, the same browser will serve an uncorrupted image from my Mac's Apache instance and a corrupt image from the VM. When I disable all PNG optimizations except PNGCrush, and the removal of the PNG metadata, the image is served corrupted. I'm optimizing JPEG images with JPEGmini. The server is running CentOS 5.9, Apache 2.2.3-85, PHP 5.3.3, and Drupal 7. As best as I can tell the error lies somewhere within the VM, either with Apache or with (perhaps) the network stack. Seems like the tools that optimize the compression of the PNGs and JPEGs are what trigger this error. I've already determined that the .htaccess file isn't interfering with how the images load. What should I try to troubleshoot this?

  • One single page showing 3 requests (also printing the headers)

    - by Korcholis
    Someone in my studio designed a webpage some years ago, and now the client decided to change the server (he moved to a Linux Apache server running Gen2 SMP, 64 bits, PHP version 5.3.8, Standard MYSQL version 5). It suddenly started to do weird things. When clicking on a link that requires login, the page redirects you to the login page using header() function in PHP. Curiously, the page shows this: OK The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, [no address given] and inform them of the time the error occurred, and anything you might have done that may have caused the error.

I also checked the .htaccess, everything was correct (RewriteBase was / as intended, and the only stuff there is another rule that moves ^en/ requests to request?lang=en. Has anyone faced something like this? Edit: IE doesn't trigger these two headers. This is getting wierder.

  • What could cause a dual-monitor PC to suddenly stop using one of the screens?

    - by raldi
    I've got a dual-monitor setup using a GeForce 7900GT that was working fine for over a year... then suddenly, only one of the screens works. It's not OS-related, because even on startup, only one screen displays the BIOS checks. In the past, both screens would show it together. I didn't change anything to trigger this The monitor that gets a signal is random -- sometimes the one on the left goes black, sometimes the one on the right. The monitors and their cables are good -- I can switch both or either, and I get a signal just fine. They're plugged in, too. It's not the video card, either -- I have an identical 7900GT in another machine, and swapping the two didn't fix anything. It's not dust on the motherboard -- I pulled everything out, cleaned it off, checked for obvious damage, put it all back together, and no change. My next two steps are going to be to reset the CMOS info and to try swapping out the motherboard. Before I do that, does anyone have any other ideas?

  • Possible Hack with FTP - What are the solutions?

    - by iamrohitbanga
    I was reading the FTP rfc and hence had this idea. Suppose there are several public ftp servers that allow anonymous user login. I open a control connection on port 21 to each of these servers. Now suppose there is a web server a.com with ip address x.y.z.w listening on port 80. FTP allows a user to specify the host on which the data connection is to be setup. So a user specifies the host and port number of a.com web server. Now the ftp server starts sending data to a.com for which it is not a valid HTTP request and hence it is rejected. But a.com notes that the invalid http request came from a public ftp server and not my ip address. Can this not lead to a distributed attack by utilizing all public ftp servers. worse still the the data being sent by ftp server could be a valid http request which could trigger a.com to send a file back to the ftp server. Is there a solution for this or is it no problem at all.

  • Create a wifi hotspot in a place where an authentication is required [closed]

    - by SoftTimur
    I live in a residence where Internet is provided via cable. Once the computer is connected to the cable, launching a browser will trigger an authentication, I have a username and password to enter, then the internet will be connected. With a gateway (e.g. Wireless Cable Voice Gateway Model CBVG834G) and 2 cables, two PCs can connect to the Internet with my account at the same time. Now the question is, I don't like the cable, and would like to create a wifi hotspot. It seems realizable with the same gateway. According to the instruction on page 2-4 of the manual: Enter http://192.168.0.1 in the address field of your Internet browser. Log in to the gateway with either of the default user names, MSO or admin... However, trying to open 192.168.0.1 gives me an error on the browser. Does anyone know what happened? Is it due to the authentication required by my residence? Is there any other way to build a hotspot of wifi? PS: My system is MAC OS

  • Bindable richTextBox still hanging in memory {WPF, Caliburn.Micro}

    - by Paul
    Hi, I use in WFP Caliburn.Micro Framework. I need bindable richTextbox for Document property. I found many ways how do it bindable richTextBox. But I have one problem. From parent window I open child window. Child window consist bindable richTextBox user control. After I close child window and use memory profiler view class with bindabelrichTextBox control and view model class is still hanging in memory. - this cause memory leaks. If I use richTextBox from .NET Framework or richTextBox from Extended WPF Toolkit it doesn’t cause this memory leak problem. I can’t identified problem in bindable richTextBox class. Here is ist class for bindable richTextBox: Base class can be from .NET or Extended toolkit. /// <summary> /// Represents a bindable rich editing control which operates on System.Windows.Documents.FlowDocument /// objects. /// </summary> public class BindableRichTextBox : RichTextBox { /// <summary> /// Identifies the <see cref="Document"/> dependency property. /// </summary> public static readonly DependencyProperty DocumentProperty = DependencyProperty.Register("Document", typeof(FlowDocument), typeof(BindableRichTextBox)); /// <summary> /// Initializes a new instance of the <see cref="BindableRichTextBox"/> class. /// </summary> public BindableRichTextBox() : base() { } /// <summary> /// Initializes a new instance of the <see cref="BindableRichTextBox"/> class. /// </summary> /// <param title="document">A <see cref="T:System.Windows.Documents.FlowDocument"></see> to be added as the initial contents of the new <see cref="T:System.Windows.Controls.BindableRichTextBox"></see>.</param> public BindableRichTextBox(FlowDocument document) : base(document) { } /// <summary> /// Raises the <see cref="E:System.Windows.FrameworkElement.Initialized"></see> event.

It’s Ok. But then I try bindable richTextBox: Child window 2: <Window x:Class="WpfApplication2.Window2" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Controls="clr-namespace:WpfApplication2.Controls" Title="Window2" Height="300" Width="300"> <Grid> <Controls:BindableRichTextBox Background="Red" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Auto" FontSize="13" Margin="4,4,4,4" Grid.Row="0" /> </Grid> </Window> Open child window 2, close this child window and in memory are still alive object of this child window also bindable richTextBox object.

  • Azure Diagnostics wrt Custom Logs and honoring scheduledTransferPeriod

    - by kjsteuer
    I have implemented my own TraceListener similar to http://blogs.technet.com/b/meamcs/archive/2013/05/23/diagnostics-of-cloud-services-custom-trace-listener.aspx . One thing I noticed is that that logs show up immediately in My Azure Table Storage. I wonder if this is expected with Custom Trace Listeners or because I am in a development environment. My diagnosics.wadcfg <?xml version="1.0" encoding="utf-8"?> <DiagnosticMonitorConfiguration configurationChangePollInterval="PT1M""overallQuotaInMB="4096" xmlns="http://schemas.microsoft.com/ServiceHosting/2010/10/DiagnosticsConfiguration"> <DiagnosticInfrastructureLogs scheduledTransferLogLevelFilter="Information" /> <Directories scheduledTransferPeriod="PT1M"> <IISLogs container="wad-iis-logfiles" /> <CrashDumps container="wad-crash-dumps" /> </Directories> <Logs bufferQuotaInMB="0" scheduledTransferPeriod="PT30M" scheduledTransferLogLevelFilter="Information" /> </DiagnosticMonitorConfiguration> I have changed my approach a bit. Now I am defining in the web config of my webrole. I notice when I set autoflush to true in the webconfig, every thing works but scheduledTransferPeriod is not honored because the flush method pushes to the table storage. I would like to have scheduleTransferPeriod trigger the flush or trigger flush after a certain number of log entries like the buffer is full. Then I can also flush on server shutdown. Is there any method or event on the CustomTraceListener where I can listen to the scheduleTransferPeriod? <system.diagnostics> <!--http://msdn.microsoft.com/en-us/library/sk36c28t(v=vs.110).aspx By default autoflush is false.
