• Can't install Ubuntu 12.04 64-bit on a dual-drive MacBook Pro 8,2

  - by kizdp

  Good afternoon, this is the first time I participate here as I'm new to Linux. I've been trying to solve the following problem for over a week without any sign of success so I hope there's a much more knowledgeable person here that can give me a solution. I have an early 2011 MacBook Pro (8,2) with Mac OS X running in a SSD. Then, instead of the Optical bay, I have a HDD in where I would like to install Ubuntu to run it natively. I've tried to do the normal installation process, with or without rEFIt, but it seems the problem resides on the communication between the device containing the Ubuntu .iso file and the laptop. It doesn't allow communication with the boot CD or USB drive. It usually says: “Loading bootlogo...” after I click on the “boot from CD, Linux Icon”. After trying several things, I would like to know if I could install Ubuntu on the HDD as an external HDD (using a friend's Window's system) and then simply put it back into my laptop so as to become an Internal HDD again. I guess, I would have to reinstall many drivers and so on, but would this approach work? Thanks in advance and sorry for this huge block of text

• Approach to Authenticate Clients to TCP Server

  - by dab

  I'm writing a Server/Client application where clients will connect to the server. What I want to do, is make sure that the client connecting to the server is actually using my protocol and I can "trust" the data being sent from the client to the server. What I thought about doing is creating a sort of hash on the client's machine that follows a particular algorithm. What I did in a previous version was took their IP address, the client version, and a few other attributes of the client and sent it as a calculated hash to the server, who then took their IP, and the version of the protocol the client claimed to be using, and calculated that number to see if they matched. This works ok until you get clients that connect from within a router environment where their internal IP is different from their external IP. My fix for this was to pass the client's internal IP used to calculate this hash with the authentication protocol. My fear is this approach is not secure enough. Since I'm passing the data used to create the "auth hash". Here's an example of what I'm talking about: Client IP: 192.168.1.10, Version: 2.4.5.2 hash = 2*4*5*1 * (1+9+2) * (1+6+8) * (1) * (1+0) Client Connects to Server client sends: auth hash ip version Server calculates that info, and accepts or denies the hash. Before I go and come up with another algorithm to prove a client can provide data a server (or use this existing algorithm), I was wondering if there are any existing, proven, and secure systems out there for generating a hash that both sides can generate with general knowledge. The server won't know about the client until the very first connection is established. The protocol's intent is to manage a network of clients who will be contributing data to the server periodically. New clients will be added simply by connecting the client to the server and "registering" with the server. So a client connects to the server for the first time, and registers their info (mac address or some other kind of unique computer identifier), then when they connect again, the server will recognize that client as a previous person and associate them with their data in the database.

• Ubuntu 12.04 dual monitor reset bug

  - by Tentresh

  My two displays are: Intel GMA x4500 Laptop (1280x800 native resolution of the built-in display) External display (1920x1080) Few minutes after I login to my dual monitor setup its get reset to mirror screens. If I restore the settings via displays application everything is fine.

Can this be solved within Ubuntu? I like it's interface, but manually fiddling with resolution on every login is not bearable.

• Ubuntu 11.04 64bits Keeps Randomly Freezing

  - by user971602

  This has been a real headache for me since the number of freezes has increase from twice a week to about 1 or twice a day. The system just halts and nothing can be done but hitting the restart button. At the beginning I thought it was related to Flash since I was getting random freezes when playing full screen flash videos online. I also thought it could be the wireless pci card. But the system has freezed using browsing around GNOME. The truth is, the freezes are really random and strange. I checked this thread Ubuntu keeps randomly freezing and try to ssh my computer using another one, but I could not ssh since it was really totally frozen. NumLock or CapsLock wasn't responding or blinking. Since I could not ssh I, also ignored this article https://wiki.ubuntu.com/X/Troubleshooting/Freeze According to my wife, the system has also halted under Win7 Pro 64bit but with less frequency. Here is my system configuration Intel Core i7 2600k ASRock Z68 Extreme3 gen3 Motherboard Crucial M4 128GB CT128M4SSD2 SSD WD Caviar Green WD10EADS 1TB SATA II G.SKILL Ripjaws X Series 8GB (2 x 4GB) DDR2 OCZ ModXStream 600W Power Supply Rosewill RNX-N300X PCI Wireless Adapter No external Graphics Card I remove the Wireless card and used Ethernet to see if the problem was the that, but I got a freeze after doing that. I also ran memtest86 and everything was ok. The only other thing I might suspect of is the SSD. I will try to clone the SSD to a HDD to see if that solve the problem. At this point I am stuck with the freezes. Do anyone have a clue of why this is happening and how can i solve this?

• Blank screen during boot after clean Ubuntu 11.10 install (Intel N10 graphics)

  - by Coen

  After a clean install of Ubuntu 11.10 on my Asus eee PC 1005p, Ubuntu seems to boot correctly, except for initialization of the LCD screen. What I observe: I choose Ubuntu 11.10 in the GRUB 2 menu A blank screen with a blinking cursor in the top left of the screen, for 15-20 seconds. The ubuntu logo with 5 red dots in the center of the screen, for 1 second. The LCD screen is entirely blank The startup sound plays (Ubuntu is configured to auto-login) Still, the LCD screen is entirely blank. When I press Fn-F8 (the switch between LCD screen and external VGA), the LCD screen shows my desktop correctly and everything seems to work fine. Except for the adjust contrast buttons (Fn-F5 and Fn-F6), these seem to cycle through random brightness modes. Something like: 0% - 50% - 20% - 0% - 20% - 0% Any ideas what's causing this or how to solve this? coen@elpicu:~$ lspci -v 00:02.0 VGA compatible controller: Intel Corporation N10 Family Integrated Graphics Controller (prog-if 00 [VGA controller]) Subsystem: ASUSTeK Computer Inc.

• Facebook contest policy no-no?

  - by Fred

  I would like to post a link on a Facebook page where it will exit Facebook entirely and go to a client's website, where people will be on a page (client's) where they can enter their e-mail address to be entered in a temporary database file with rules and disclosures etc., for a draw once the number of entries reaches 100 for instance. Once the number of entries reaches 100, a random winner is picked and notified via E-mail. The functionality is as follows: A link is place on a Facebook page leading to an external page The page is a form to merely enter their email address for a contest The email is placed in a temporary file An automatic E-mail is sent to the address used for confirmation using SHAH-256 hash The person receives the Email saying something to the affect "Please confirm your Email address etc. - If you did not authorize this, simply ignore this message and no further action will be taken". If the person clicks on the confirmation link, the Email is then stored in the database and the person is again notified saying "Thank you for signing up etc." Once others do the same process and the database reaches a certain number, the form is no longer accessible and automatically picks a random Email. Once picked, an Email is automatically sent to the winner stating the instructions, and notifying me also. Once that person clicks yet another confirmation link, the database is then automatically deleted. I have built this myself and have no intentions of breaking any rules, nor jeopardize the work/time/energy I have put into this project. Is this allowed?

• Dell Inspiron7520 and ubntu 12.04 issues

  - by user91358

  I have a DELL Inspiron 7520 in the highest configuration: 3rd Generation Intel® Core™ i7-3612QM processor (6M Cache, up to 3.1 GHz) 15.6" Full High Definition (1080p) LED Display 8GB3 Dual Channel DDR3 SDRAM at 1600MHz 1TB 5400RPM SATA HDD + 32GB mSATA SSD w/Intel Smart Response Blu-ray Disc (BD) Combo (Reads BD and Writes to DVD/CD) AMD Radeon™ HD 7730M 2GB 6.09 lbs and I have installed Ubuntu 12.04 few days ago and I'm facing some issues: 1) sometimes the whole ntb freezes and I have to hold power button for 5 secs to shut it down. I think it is something with VGA and connected external monitor. I have read somewhere that it is already a reported bug, but what I am not sure about that it is doing sporadically. Sometimes it freezes right after I log in, sometime I ran few hours and then it freezes. I am using those proprietary drivers but I wasn't been able to install those with updates. 2) the next issue is the fan is quite noisy even when the ntb is almost Idle. (max 10% CPU usage). Can you recommend me some software which could do this power management to lower the noise? I have tried CPU frequency scaling indicator, but it seems that it has not any effects. 3) and issue no. 3: when I want to log out, restart or shutdown using the menu in upper right corner the upper and left trays disappear, but programs are still running and they won't close to complete log out or shutting down the OS. When I use the CLI command, it works fine. Thanks for any help you can provide.

• How to Activate wifi in Toshiba Satellite C655?

  - by user4106

  I've recently bought a Toshiba Satellite C655. It came with Windows 7 preinstalled. I've never had a notebook before, but as a desktop user, I was a Ubuntu user since 2 years, and I've never had a problem with drivers, wifi, etc. When I tried to install the Ubuntu 10.04, and also the new and fresh 10.10, in my new laptop, I experienced some troubles with some of the componentes of my computer. For example, I was not able to activate my wi-fi card, although I know the kernel recognizes it correctly, because when doing "lspci" at the terminal, it was listed. Anyhow, I'm not able to "activate" the wifi, or whatever it's necessary to do in order to be able to search for public networks available, and to connect with them. The wifi-card the laptops brings is the (the lspci output): 03:00.0 Network Controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) [168c:002b] (rev 01). It's anything in you can help me? Thanks a lot in advance! Edit Neither solution seems to work. In first place, i've tried installig what hhlp told me. After the installation, nothing seems to change: on right-clicking the wireless icon, it seems to recognize the card, because the option "Enable wifi" was ticked. But, once again, i was not able to "turn the wi-fi" on. In second place, i didn't try installing the drives, because the card is already recongnized. The issue is that i cannot seem to turn it on! One thing i've probably missed is that the Toshiba cames with a windows sofntware that allows you to enable / disable the wifi tools. So, it does not have an external "button" to turn it off. I don't know if that's the problem, but i have the feeling that the issue may be aroud there: in how to turn ON the wifi-signal (or to verify if it's on or off) in my ubuntu.

• Problem with dual monitor

  - by Gernot

  I have a laptop with a nvidia optimus graka. I'm also useing a 23" external monitor. It never really worked... . After installation (it was a clean installation) the 23" monitor worked as it should, but the LCD from the laptop wasn't at the right resolution. And every time i tried to change this the PC crashed. Today i had a litle bit of time so i decided to solve this problem. I've tried a few things ( e.g. I've installed bumblebee with the nvidia driver and tested it. It's working...) but nothing solved my problem. Instead of getting any closer to the solution, it's gotten even more strange now... . Now, the display setting isn't recognizing a 2nd monitor at all. But I get on the 23" monitor (which is not shown in the display setting) a screen with the same resolution as the one on the laptop. The display settings looks so: Any help would be wonderful.

• ubuntu 12.04 will not play DVDs

  - by ayelet

  First off, I'm not just a newbie, I'm clueless! So your answers will need to be in complete idiot language (let's say I'm computer saavy, and I can follow directions,but I've never programmed anything and assume I don't understand any abbreviations. So why am I running linux? b/c windows was driving me nuts!! and my friend convinced me. day-to-day operations, we're doing fine, but when it comes to problems, I've got no clue what I'm doing!) So here's what's going on, my machine is an HP pavilion dv6, my optical drive is a standard cd/dvdrw, when i load an audio cd of any type (burned, official, etc,..) I have no problems, when I pop in a dvd - i get nothing. the dvd icon comes up in my launch tray, when I open VLC player I can find the dvd in the folder... but it won't play. I can watch movies I've downloaded with no problem, I can also watch movies off an external hard drive. The only thing I've tried is removing vlc and reinstalling, and I tried installing a different player (gnome maybe? I don't remember). none of that worked. Again, i can follow directions, but you need to be very specific and don't assume I know anything going in. (I mean, I know basic stuff, but nothing too technical.) PLEASE HELP!!! MY KIDS ARE DRIVING ME CRAZY!!! Thanks!!

• How to dual boot Ubuntu 12.10 and Windows XP sp3 on Dell Dimension 8250 desktop using 2 hard drives

  - by user106055

  I'd like instructions to dual boot Ubuntu 12.10 and Windows XP (sp3) on my desktop Dell Dimension 8250 (this is old and has 1.5 GB RAM which is maximum). I will be using 2 hard drives. Windows XP is already on a 120 GB drive and and Ubuntu 12.10 will go on a separate 80 GB hard drive. Both drives are IDE using a 80 conductor cable where the 40 pin blue connector connects to the motherboard. The middle connector is gray and is "normally" used for slave (device 1) and the black connector at the very end of the cable is meant for the master drive (device 0) or a single drive if only one is used. First, I do not wish the XP drive to have its boot modified by Ubuntu in any way. It should remain untouched...virgin. Let me know where the XP drive and the Ubuntu drive should be connected based upon the cable I've mentioned above, as well as jumper settings for both during the whole process. I'm just guessing, but should I remove the XP drive and put the empty Ubuntu drive in its place and install Ubuntu? By the way, I already have made the DVD ISO disk. For your information, the BIOS for this machine is version A03. When I tap F12 to get to the boot menu, I have the following choices: Normal (this will take me to a black screen with white type giving me the choice to boot to XP or to my external USB backup recovery drive) Diskette Drive Hard-Disk Drive c: IDE CD-ROM Drive (Note that if the CD Drive is empty, it will then go to the DVD drive) System Setup IDE Drive Diagnostics Boot to Utility Partition (This is Dell's various testing utilities) Thank you in advance for your help.

• Data recovery on a Samsung SV1203N HDD

  - by Jim Conace

  Let me start by saying that I am a beginner in Ubuntu, but pretty knowledgeable with Windows. I am having a strange problem trying to recover data from a Samsung SV1203N HDD (120 GiB). I have tried numerous things in both Windows 7 and Ubuntu 12.04 LTS (on a flash drive, an external HDD and a Live CD). This drive has some very important data on it and I am praying some of you Ubuntu geeks can help me get it back. Here's my problem. The HDD is clicking while I am booting, but it stops when I get into Ubuntu or Windows. It refuses to be detected in the bios, so I cant perform any tests on it. I have tried numerous things in both Windows (repair CD, Jumpers, etc.) and Ubuntu (Boot-Fix, GParted, Testdisk, Photorec, forcing a mount, etc.). But it all seems to lead me back to the fact that the drive is not being recognized in the BIOS. I've even tried chilling the drive in the fridge, which worked well for another drive I work on, and I recovered all of the data in Ubuntu flawlessly. I am assuming that since the drive stops clicking when I get into the OS' that there is hope for recovery. I am going to try an IDE/SATA to USB cable, and replacing the Logic Board, but I want to exhaust all other possibilities before I do that. Any help would be greatly appreciated Bye

• how to recover lost partitions data

  - by TheJoester

  I have a 2TB SATA drive that was being used as file storage on my UBUNTU computer. I was re-imaging my windows box so I used that drive to back up some files to it. I did this by taking the drive from my windows PC and putting it in my UBUNTU PC, mounted it and copied the files over. After the windows refresh I thought it would be easier to take the 2 TB drive and dock it in the external dock my Windows case has built in. Anyway it would recognize in BIOS but windows would not see it (because it was EXT3 or EXT4) so when I went into the disk manager it advised me the drive needed to be initialized. Me not thinking I initialized it as a GUID Partition table. Now it sees it as a blank drive, even in UBUNTU. I have done nothing else to write or change the drive. I was wondering if there is a qay to repair the old partitioning and get access to my files back? many thanks! EDIT: I followed the instructions in the link @kniwor sent me. I used the command sudo gpart -W /dev/sda /dev/sda and here was the result: Guessed primary partition table: Primary partition(1) type: 007(0x07)(OS/2 HPFS, NTFS, QNX or Advanced UNIX) size: 0mb #s(1) s(2861671176-2861671176) chs: (1023/254/63)-(1023/254/63)d (178130/202/1)-(178130/202/1)r Primary partition(2) type: 007(0x07)(OS/2 HPFS, NTFS, QNX or Advanced UNIX) size: 0mb #s(1) s(3484550160-3484550160) chs: (1023/254/63)-(1023/254/63)d (216903/55/1)-(216903/55/1)r Primary partition(3) type: 000(0x00)(unused) size: 0mb #s(0) s(0-0) chs: (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r Primary partition(4) type: 000(0x00)(unused) size: 0mb #s(0) s(0-0) chs: (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r Not sure it found what I wanted. suggestions?

• Is my htaccess setting hurting SEO?

  - by Ramanonos

  I have a site that I have redirecting to https. I do this to leverage wildcard SSL for my password protected pages. Everything seems to work fine with testing. For example, whether you type in http or www, you always get redirected to the SSL https... That said, I have about 200-300 external backlinks -- many high quality, yet google webmaster (along with SEOMoz), shows I have just 4... Huh? I'm embarrassed to say I just discovered this. This has led me to hypothesize that maybe my settings in htaccess is messed up, so google isn't recognizing a link because it's recorded on another site as http, instead of https. Maybe? At any rate, here is my simple htaccess setting for 301 www to http, and from http to https. RewriteCond %{SERVER_PORT} !443 RewriteCond %{HTTP_HOST} ^www\.example\.com$ [NC] RewriteRule ^(.*)$ http://example.com/$1 [L,R=301] RewriteCond %{SERVER_PORT} 443 RewriteCond %{HTTP_HOST} ^www\.example\.com$ [NC] RewriteRule ^(.*)$ https://example.com/$1 [L,R=301] Like I said, everything works fine for redirect over https, so I'd rather not screw up what works. On the other hand something is very wrong with google finding all my back links, so I need to fix something... I'm just wondering that maybe google isn't picking up a my backlinks from other websites recording me as http because I'm at https. Maybe google doesn't care and it's some other issue. Am I barking up the right tree? If so any quick fixes? Thanks as always!

• Lost all non-linux hard drives

  - by Rick

  I've somehow lost access to all my non-linux drives. I'm not sure how. I have two other hard drives set up (a windows boot and an external usb I was using under windowsxp). A few days ago I could access both under linux with no problem. Now, I see them listed under media, but when I click on them, nothing is there (same thing happens when I go there in a term window). Now, the computer (under linux) sees them, but I can't see anything in them. (in nautilus it shows "(Empty)") Any ideas what happened or how to get access to them again? My guesses as to what might have caused it: -I was trying to set up AdobeAIR (unsuccessfully) and had to make and remove a couple of symbolic links. Never got that to work but maybe links I made or removed did something? -I was also trying to set up nautilus so that I could enter it with sudo permission. I also didn't figure out how to do that successfully, but maybe something I did while trying messed it up? (I think I installed and uninstalled nautilus-actions configuration tool). Note: I'm working on a relatively new install of 12.04

• Drupal site Instant Messaging [migrated]

  - by pthurmond

  I am trying to find a module or a standalone solution that I can turn into a module that will allow me to have an instant messaging system like Facebook does on a Drupal site that I am working on. I have never setup a chat system before. My particular requirements are rather stringent. It needs to be a solution where we host the chatting server (if one is needed separate from the website itself). It must use the site's login state (can't use an external system at all, that means no GTalk, Yahoo IM, or AIM). It also must be able to handle up to 1,000 users at any given time. I have looked through the Drupal community and I tried the DXMPP module, but it requires Jquery UI 1.8 and that doesn't work with all of the other things that my site uses (such as Homebox). We do have a Jabber server already setup and ready to go. Does anyone have any thoughts or options here? Thanks! EDIT: We are using Drupal 6.

Moreover, it redirects all mysql and 13000-13004..etc port connections to a specific local ip in the same port, which is 192.168.1.100. But what I find strange is that when my firewall is active, it blocks absolutely all the input connections, even those which must not block (http, mysql). In fact, I'm literally blocked and I can't establish any external connection. What am I doing wrong? PS: I tested the firewall without those redirections, and it still block all inputs, so I suppose it's not the problem.

• What is the correct way to code incoming links for SEO?

  - by DC01

  Our site is giving out 'badges' to our authors. They can post these on their personal blogs and they will serve as incoming links to our site. We want to give out the best possible code for SEO without doing anything that would get us flagged. I would like to know what you're thoughts are on the following snippet of code and if anyone has any DEFINITE advice on dos and donts with it. Also, let me know if any of it is redundant or not worth it for SEO purposes. I've kept the css inline since some of the writers would not have access to add link to external CSS. I've changed the real values, but title, alt etc would be descriptive keywords similar to our page titles etc (no overloading keywords or any of that) <div id="writer" style="width:100px;height:50px;> <h1><strong style="float:left;text-indent:-9999px;overflow:hidden;margin:0;padding:0;">articles on x,y,z</strong> <a href="http://www.site.com/link-to-author" title="site description"> <img style="border:none" src="http://www.site.com/images/badge.png" alt="description of articles" title="View my published work on site.com"/> </a> </h1></div>

• What tools do I have to disuade users from using the same password with similar systems?

  - by Resorath

  I'm building a web application that connects to other web services (using strictly anonymous binding, so no user passwords are being used). However the web application maintains its own users itself, and is required to ask certain details such as e-mail addresses and public linking information to these other web services (for example, a username but not a password). I want to deter or prevent users from reusing passwords in my application that they have also used in the applications I'm linking to. For example, if I ask for their e-mail and provide me with their gmail address, I don't want them using their gmail password for my system. Another example would be reusing a password to a linked system in which they also gave me their username. One idea I had was to simply try using the information they gave me, along with the password they are trying to store and log in to these external web applications to test the password - then immediately unbind if I was successful and ask the user to use a different password. However I suspect there is a host of morale and legal issues there. The reason this is a big deal to me is accountability. My application is simply not funded enough to invest properly in security around user passwords. A salted, hashed password in a public SQL-like database is as secure as it gets. So if passwords and linked usernames or e-mails get out, I don't want my userbase compromised.

• what is standard approach to create a responsive website using javascript,php ajax and perhaps zend framework [closed]

  - by shawndreck

  I am working on a web system currently and plans to heavily use javascript with ajax to make the user interface more friendlier, not fancy as such. The javascript will be used for client side form validation, data loading from server and creating proper content with the result, also to for floating windows during add/edit or external references. Here is a scenerio that could clearify my question. A user wants to update card but instead of jumping to another page to verify the available colors,size and prizes of product, those information are shown in a floating window and changes in the floating window can affect the underlying one. My question is : 1. What are some of the approaches to encounter this situation? 2. Are there any helpful tips, tricks and links on this subject? I am comfortable with js,php and zend. I would appreciate any advice,tip and tricks, problem solving approach to handle a situation like this! Thanks in advance. Hope this make sense.

• Enable wireless greyed out. Disabled by hard switch. Details inside

  - by ltlunatic

  Ok so the basic issue here is this: My wireless has not once enabled through many environments. Wubi install: Enable wireless greyed out Live cd: greyed out Partition alongside win7: greyed out. I installed all software updates, checked additional drivers, installed the latest driver for RTL8111/8168B. rfkill list shows phy0 and phy1. Phy0 has a hardblock on. everything else is unblocked. Now consider this also: I have both a wireless adapter inside my laptop and a wireless usb adapter outside. The internal adapter does not work, hence why I think hardblock is on even if the external slider in 'on'. I have tried commands such as rfkill unblock all as well as sudo rfkill unblock all. No wireless options in the BIOS. I have tried another laptop and desktop and they get wireless from the get go. Ubuntu on my laptop seems to see my belkin adapter as well as my internal (ralink) one. But trying to scan networks yields no results and says network is down always. Ubuntu version: 12.04 lts Ask me anything else you may need to help me, thanks.

• using Silverlight 3's HtmlPage.Window.Navigate method to reuse an already open browser window

  - by Phil

  Hi, I want to use an external browser window to implement a preview functionality in a silverlight application. There is a list of items and whenever the user clicks one of these items, it's opened in a separate browser window (the content is a pdf document, which is why it is handled ouside of the SL app). Now, to achieve this, I simply use HtmlPage.Window.Navigate(new Uri("http://www.bing.com")); which works fine. Now my client doesn't like the fact that every click opens up a new browser window. He would like to see the browser window reused every time an item is clicked. So I went out and tried implementing this: Option 1 - Use the overload of the Navigate method, like so: HtmlPage.Window.Navigate(new Uri("http://www.bing.com"), "foo"); I was assuming that the window would be reused when the same target parameter value (foo) would be used in subsequent calls. This does not work. I get a new window every time. Option 2 - Use the PopupWindow method on the HtmlPage HtmlPage.PopupWindow(new Uri("http://www.bing.com"), "blah", new HtmlPopupWindowOptions()); This does not work. I get a new window every time. Option 3 - Get a handle to the opened window and reuse that in subsequent calls private HtmlWindow window; private void navigationButton_Click(object sender, RoutedEventArgs e) { if (window == null) window = HtmlPage.Window.Navigate(new Uri("http://www.bing.com"), "blah"); else window.Navigate(new Uri("http://www.bing.com"), "blah"); if (window == null) MessageBox.Show("it's null"); } This does not work. I tried the same for the PopupWindow() method and the window is null every time, so a new window is opened on every click. I have checked both the EnableHtmlAccess and the IsPopupWindowAllowed properties, and they return true, as they should. Option 4 - Use Eval method to execute some custom javascript private const string javascript = @"var popup = window.open('', 'blah') ; if(popup.location != 'http://www.bing.com' ){ popup.location = 'http://www.bing.com'; } popup.focus();"; private void navigationButton_Click(object sender, RoutedEventArgs e) { HtmlPage.Window.Eval(javascript); } This does not work. I get a new window every time. option 5 - Use CreateInstance to run some custom javascript on the page private void navigationButton_Click(object sender, RoutedEventArgs e) { HtmlPage.Window.CreateInstance("thisIsPlainHell"); } and in my aspx I have function thisIsPlainHell() { var popup = window.open('http://www.bing.com', 'blah'); popup.focus(); } Guess what? This does work. The only thing is that the window behaves a little strange and I'm not sure why: I'm behind a proxy and in all other scenarios I'm being prompted for my password. In this case however I am not (and am thus not able to reach the external site - bing in this case). This is not really a huge issue atm, but I just don't understand what's goign on here. Whenever I type another url in the address bar of the popup window (eg www.google.com) and press enter, it opens up another window and prompts me for my proxy password. As a temporary solution option 5 could do, but I don't like the fact that Silverlight is not able to manage this. One of the main reasons my client has opted for Silverlight is to be protected against all the browser specific hacking that comes with javascript. Am I doing something wrong? I'm definitely no javascript expert, so I'm hoping it's something obvious I'm missing here. Cheers, Phil

• ASMX Web Services with SOAP Extension

  - by digitall

  I am in the process of setting up a web service for an external client to connect to my client's application and update some information. I went the ASMX route (the rest of the application runs on WCF) because I knew the external client could be very difficult to deal with and I was trying to keep everything as simple as possible. They also aren't a .Net shop which makes things worse. After getting the service setup for them I provided the ASMX URL for them to see how to format the SOAP headers/message content. They have since come back and told me their tool is unable to send them in the format required by .Net and I can either come up with a different way to accept messages or we have to go with FTP. Based on this I have been researching how to intercept their message, reformat it the way my service requires it (which means adding two lines), and then let it process. This path led me to SOAP Extensions which I have been trying to work with but can't seem to figure out. When I have my sample application call the web service from the generated code Add Web Reference provides everything works great until I add in my extension. All it currently does is override ChainStream setting an internal stream equal to the one being passed in and returning a new stream, like this: private Stream newStream = null; private Stream oldStream = null; public override Stream ChainStream(Stream stream) { this.oldStream = stream; this.newStream = new MemoryStream(); return newStream; } I also override ProcessMessage and in it take the contents of oldStream and set newStream equal to that and then write to a different stream with an XmlWriter. I take that new stream and using a StreamReader read it into a string, with the end goal being manipulating it here and setting newStream (which is being used by ChainStream) equal to the contents of this. Here is that piece: public override void ProcessMessage(SoapMessage message) { switch (message.Stage) { case SoapMessageStage.BeforeDeserialize: this.Process(); break; default: break; } } private void Process() { this.newStream.Position = 0L; XmlTextReader reader = new XmlTextReader(this.oldStream); MemoryStream outStream = new MemoryStream(); using (XmlWriter writer = XmlWriter.Create(outStream)) { do { writer.WriteNode(reader, true); } while (reader.Read()); writer.Flush(); } outStream.Seek(0, SeekOrigin.Begin); StreamReader streamReader = new StreamReader(outStream); string message = streamReader.ReadToEnd(); newStream = outStream; newStream.Seek(0, SeekOrigin.Begin); streamReader.Close(); } By running this, which seems to me like it would be fine, my test application gets a 400 Bad Request back from the service. If I either don't use the extension or I don't do anything in ProcessMessage everything seems fine. Any suggestions to this? As a side note, once I get this working with the generated code from the WSDL I will be moving to a WebRequest to try sending the message to the service. Currently that bombs out with a 415 Unsupported Media Type response. I'm trying to keep this post to one question but if anyone has any tips with using a WebRequest to connect to an ASMX service it would be much appreciated!
