  • how to check how many bits in a byte array?

    - by newandfresh
    Im creating a download speed test, and im downloading a 800megabit file to a Byte[] in a memory stream with webClient.DownloadDataAsync(new Uri(link), memStreamArray); How can i check how many bits are in the memStreamArray while downloading? I need this so i can do a calculation on size / time to get the speed in realtime. Im planing on performing this calculation in the webClient.DownloadProgressChanged event.

  • Scan a Windows PC for Viruses from a Ubuntu Live CD

    - by Trevor Bekolay
    Getting a virus is bad. Getting a virus that causes your computer to crash when you reboot is even worse. We’ll show you how to clean viruses from your computer even if you can’t boot into Windows by using a virus scanner in a Ubuntu Live CD. There are a number of virus scanners available for Ubuntu, but we’ve found that avast! is the best choice, with great detection rates and usability. Unfortunately, avast! does not have a proper 64-bit version, and forcing the install does not work properly. If you want to use avast! to scan for viruses, then ensure that you have a 32-bit Ubuntu Live CD. If you currently have a 64-bit Ubuntu Live CD on a bootable flash drive, it does not take long to wipe your flash drive and go through our guide again and select normal (32-bit) Ubuntu 9.10 instead of the x64 edition. For the purposes of fixing your Windows installation, the 64-bit Live CD will not provide any benefits. Once Ubuntu 9.10 boots up, open up Firefox by clicking on its icon in the top panel. Navigate to http://www.avast.com/linux-home-edition. Click on the Download tab, and then click on the link to download the DEB package. Save it to the default location. While avast! is downloading, click on the link to the registration form on the download page. Fill in the registration form if you do not already have a trial license for avast!. By the time you’ve filled out the registration form, avast! will hopefully be finished downloading. Open a terminal window by clicking on Applications in the top-left corner of the screen, then expanding the Accessories menu and clicking on Terminal. In the terminal window, type in the following commands, pressing enter after each line. cd Downloadssudo dpkg –i avast* This will install avast! on the live Ubuntu environment. To ensure that you can use the latest virus database, while still in the terminal window, type in the following command: sudo sysctl –w kernel.shmmax=128000000 Now we’re ready to open avast!. Click on Applications on the top-left corner of the screen, expand the Accessories folder, and click on the new avast! Antivirus item. You will first be greeted with a window that asks for your license key. Hopefully you’ve received it in your email by now; open the email that avast! sends you, copy the license key, and paste it in the Registration window. avast! Antivirus will open. You’ll notice that the virus database is outdated. Click on the Update database button and avast! will start downloading the latest virus database. To scan your Windows hard drive, you will need to “mount” it. While the virus database is downloading, click on Places on the top-left of your screen, and click on your Windows hard drive, if you can tell which one it is by its size. If you can’t tell which is the correct hard drive, then click on Computer and check out each hard drive until you find the right one. When you find it, make a note of the drive’s label, which appears in the menu bar of the file browser. Also note that your hard drive will now appear on your desktop. By now, your virus database should be updated. At the time this article was written, the most recent version was 100404-0. In the main avast! window, click on the radio button next to Selected folders and then click on the “+” button to the right of the list box. It will open up a dialog box to browse to a location. To find your Windows hard drive, click on the “>” next to the computer icon. In the expanded list, find the folder labelled “media” and click on the “>” next to it to expand it. In this list, you should be able to find the label that corresponds to your Windows hard drive. If you want to scan a certain folder, then you can go further into this hierarchy and select that folder. However, we will scan the entire hard drive, so we’ll just press OK. Click on Start scan and avast! will start scanning your hard drive. If a virus is found, you’ll be prompted to select an action. If you know that the file is a virus, then you can Delete it, but there is the possibility of false positives, so you can also choose Move to chest to quarantine it. When avast! is done scanning, it will summarize what it found on your hard drive. You can take different actions on those files at this time by right-clicking on them and selecting the appropriate action. When you’re done, click Close. Your Windows PC is now free of viruses, in the eyes of avast!. Reboot your computer and with any luck it will now boot up! Alternatives to avast! If avast! and a liberal amount of Googling doesn’t fix your problem, it’s possible that a different virus scanner will fix your obscure issue. Here are a list of other virus scanners available for Ubuntu that are either free or offer free trials. See their support forums for help on installing these virus scanners. Avira AntiVir Personal for Linux / Solaris Panda Antivirus for Linux Installation and usage guide from Ubuntu F-PROT Antivirus for Linux ClamAV installation and usage guide from Ubuntu NOD32 Antivirus for Linux Kaspersky Anti-Virus 2010 Bitdefender Antivirus for Unices Conclusion Running avast! from a Ubuntu Live CD can clean the vast majority of viruses from your Windows PC. This is another reason to always have a Ubuntu Live CD ready just in case something happens to your Windows installation!

  • Response.TransmitFile problem

    - by geoff
    I have the following code delivering a file to users when they click on a download link. For security purposes I can't just link directly to the file so this was set up to decode the url and transmit the file. It has been working fine for a while but recently I started having problems where the file will start downloading but there's no indication of how large the file is. Because of this when the download should stop, it doesn't. The file is about 99mb but when I download it, the browser just keeps downloading way beyond 100mb. I don't know what it's downloading but if I don't cancel it, it doesn't stop. So, my question is, is there either an alternative to transmitfile or a way to make sure the size of the file is sent also so that it stops at the right time? I don't want to use writefile because I don't want to load the entire file into memory since it's so large. Thanks. Here is the code: string filename = Path.GetFileName(url); context.Response.Buffer = true; context.Response.Charset = ""; context.Response.Cache.SetCacheability(HttpCacheability.NoCache); context.Response.ContentType = "application/x-rar-compressed"; context.Response.AddHeader("content-disposition", "attachment;filename=" + filename); context.Response.TransmitFile(context.Server.MapPath(url)); context.Response.Flush();

  • ClickOnce Deployment Error - Access to the Path is Denied

    - by michael.lukatchik
    I have a WPF app that I'm deploying to a network path using ClickOnce deployment. After the app is deployed to a network location, I use the ClickOnce html page to launch the installation process. I am successfully able to download and install the app. However, my users are not able to download and install the app. When a user navigates to the ClickOnce html page and clicks to begin the installation process, the following error message is received: ERROR SUMMARY Below is a summary of the errors, details of these errors are listed later in the log. * Activation of http://software.mycompany.com/myapp/myapp.application resulted in exception. Following failure messages were detected: + Downloading file://dev/webs/software/myapp/myapp.application did not succeed. * [4/5/2010 1:56:59 PM] System.Deployment.Application.DeploymentDownloadException (Unknown subtype) - Downloading file://dev/Webs/software/myapp/myapp.application did not succeed. All signs point to this being a security issue. So, I've done the following: Ensured that "Everyone" had read access to the files that were being deployed as part of my project Ensured that "Everyone" had read access to the network location where the app was deployed (//dev/webs/software/myapp) Ensured that "Everyone" had read access to the IIS path where the ClickOnce html page is located In each of these cases, I've made no progress in getting the app to successfully deploy via ClickOnce. Again, the odd thing is that I am able to successfully walk through the process of downloading and installing the app. It's my users, though, that need the ability to download and install the app. I've looked extensively on the web for answers, but there hasn't been much. I'd like to resolve the issue without "re-installing" or "rigging" anything. I need a solid answer. Thank you all for your input!! Mike

  • Throttle network bandwidth per application in Mac OS X

    - by Kio Dane
    I notice that iTunes seems to suck up all my bandwidth and doesn’t play nice with other applications that use the web when it's downloading. In fact, it doesn't even give itself enough bandwidth when browsing the iTunes Store while downloading large or many files (podcasts, TV shows, large apps, etc). I'm not concerned with getting all my downloads as soon as possible, they're really low priority, and I'd rather not have to do this while I'm awake, but I can't hit the refresh button if I'm in bed and forgot it already. Is there an application or tool via the Terminal to limit the download bandwidth that iTunes gets without also hindering web browsers or other applications? FOSS/GPL software is preferable, but pay software might be acceptable too.

  • Keep getting invalid IP via WiFi

    - by nmuntz
    There is something wrong with my WiFi. I keep getting an invalid IP via DHCP (169.254.x.x), this happens for ALL wifi connections (home, office, etc). If I try a Local Ethernet connection via cable it works fine. I have tried downloading the latest drivers for my wireless adapter, resetting the TCP Stack and still have this issue. One strange thing I notice is under Device Manager, Network Adapters I have 4 "Unknown Devices" and three "Remote NDIS based Internet Sharing Device". My guess is that this belongs to McAfee. Not sure if this is related or not, anyways to try to fix this I tried downloading the NetLUIDfix.exe utility from McAfee but it didn't work. Any ideas how to solve this annoying issue? Thanks!!

  • Linux wget, how to display progress percentage after session has reload?

    - by skyrail
    I am running debian Squeeze in console mode on a plug computer. I control it opening an SSH session from a Windows machine, on the same local network. I started downloading a large file using wget. What I get is a console progress bar showing the percentage of data downloaded, file size, and download rate. When I close the session, debian is still running and downloading. Fine. But When I close and reopen a session, how can see which amount of data was downloaded, using a linux command ? thanks.

  • Latency in Sending and Receiving Files From Amazon EC2 - Justification

    - by Adroidist
    I am facing a huge delay while uploading and downloading files from my Windows Amazon EC2 server to my android device. It takes around 50 seconds to upload then download 500 Kbytes image. My location is in asia and the server is is US-East. I pinged the server from my android and obtained values around 500 ms for RTT. Is this normal? How is this explained? I tried this website: http://cloudharmony.com/speedtest/run and obtained that downloading 270 Kbytes file takes around 20 seconds. How is this delay justified?

  • How to Track Duplicate Downloads

    - by user1089173
    I have a product and we are running a campaign for it to allow users to download a trial version. My questions is there any way to detect multiple downloads from the same computer but behind a proxy. For example if a person uses a proxy server, changes his/her ip and downloads our trial version multiple times from different Ip's, is there a way to detect that it is the same person who's downloading the s/w. We use only Name and Email addresses to be entered before downloading our s/w and that can easily be created. We cannot add any other fields to the form (like phoneno.)

  • Bandwidth preserving browsing mode

    - by Elazar Leibovich
    I'm looking at some methods to browse the web, in situations where bandwidth is scarce (such as, flaky wifi connection, or mobile phone internet provider who overcharges the bandwidth). One thing that would save alot of bandwidth is not downloading images while browsing. This approach has two main drawbacks Sometimes a site's layout depends of images. There are some images you wish to see (thus disabling images downloading through firefox settings is not quite convenient). I'm looking therefor for a method that would allow me to Use some heuristic to find out which images are related to the website layout and allow them to be downloaded. Select a particular image from a website, download and display it. Maybe there's a firefox extension for that?

  • How to use BT or emule across 2 or more hard drives?

    - by the searcher
    One difficulty with BT or emule is that, when the hard drive is full, we constantly need to move older files to a new hard drive so that we can download newer files. We can change BT or emule's setting so that the folder for downloading points to the new hard drive, but then, what if emule haven't finished downloading for some files that are hard to find, and it is 92% done... in that case, we would like to keep the old setting so that when the last 8% arrives, it can go into the correct file. (and same for BT, if we haven't finished some file or if we want to seed something later). So is there a good way to let BT or emule point to 2 hard drives, or somehow let the new hard drive "merge" into the existing hard drive / folder?

  • How to make iTunes download all podcast episodes irrespective of listened/not

    - by user15660
    I am a big iPod user (especially podcasts). I have used iPod touch, iPod classic and iPod nano. I noticed that iTunes stops downloading podcasts that you no longer listen to and stops downloading them. Is there a way to force iTunes to download all episodes of podcasts irrespective of whether you listen to them or not? I am not interested in just clicking a episode to make iTunes think that I'm listening. I need some kind of programmatic work around or batch script that runs and updates all podcasts/episodes automatically.

  • Thunderbird gives " Not enough disk space " alert, after trying to download more emails ( Win 7, 64 bit )

    - by James C
    So, today I have installed Mozilla Thunderbird 24.2.0 on my Windows 7 (64 bit) machine. It was downloading emails, until it hit an error. An alert showed up saying : "There is not enough disk space to download new messages. Try deleting old mail, emptying the Trash folder, and compacting your mail folders, and then try again." Now, disk space is not a problem, there is enough free space left ( almost 50 % of the drive ). How to stop the alert and continue downloading ?

  • Copying dovecot maildir to another server with courier maildir

    - by NovumCoder
    Hi all, i just moved all my mailboxes first from one server to the new one by using rsync. After that i created the folders using Thunderbird to have same folder structure like on old server. Then i copied all mail files into the folders. Now when i subscribe and click on the folder in Thunderbird it starts downloading the headers of all mails, but after finishing download nothing appears in the mail list. Its like my folder is empty and everytime i click again on the folder thunderbird starts again downloading headers. What is wrong here? I found a solution using a tool called imapsync, but its not for free, so i started doing it by copy&paste. I thought Thunderbird will be able to fix the indexes. :-( Or is there a better solution to migrate from dovecot maildir to courier maildir?

  • Is there any way to limit my Internet connection to a per program basis?

    - by Igoru
    My Linux connection is REALLY free. I live in Brazil, so where I live I can only have 1 Mbit/s. Yes I know it's sad, but it's not the point. Everytime I'm updating my Ubuntu 9.04 or downloading something, it does eat all my bandwidth. Like, while update-manager is downloading the packages, I can see by netspeed applet in my panel that the incoming traffic goes to 110 kB/s. And then, my Emesene suddenly goes disconnected, and I can't navigate. As you can imagine, I can't use my Internet connection again until the packages are all downloaded or I cancel the update in the middle. As I said, same thing happens when I'm dowloading something, but less intrusive and immediate. The question is: is there any way to limit that APT/downloads traffic to some way I can still use my other Internet services, or to reserve some bandwidth for common navigation tasks (like we have on Windows, but I forgot this thing's name, it's like "something packages".

  • Restoring Box Sync (box.com) using physical media after OS reinstall

    - by sjrm
    I have my Box Folder on a different drive ( D: ) than my Operating System Drive ( C: ) I follow these instructions to set the local folder on the second drive. https://support.box.com/hc/en-us/articles/200852947-How-Can-I-Change-the-Default-Folder-Location-for-Box-Sync- I had to format and reinstall Windows 7, leaving the other drive (D: ) untouched. now i reinstalled Box Sync, and directed it to the same location where i already have all my files. However, Box Sync renamed the folder to (Box ([email protected]) ) as a bckup, and is downloading everything again. As i have like 30Gb of files, and it takes many hour to download them, i just want to use the files that i already have in my local disk. i tried copying all files again to the new local Box Folder, but files started to get duplicated. Is there any way to avoid downloading everything again each time i reinstall my OS ? Thanks
