• Add Mirror for volumes other than the last one in Windows 7 (disk "not up-to-date")

  - by rakslice

  I'm using Windows 7 x64 Ultimate. I have an existing 4TB disk with 3 NTFS volumes, a new 3TB blank disk, and I'm trying to mirror the volumes onto the new disk. My Windows install is on an SSD which is Disk 0. The 4TB disk with volumes is Disk 1, and the new blank disk is Disk 2. I can add a mirror successfully for the last volume, but when I try to add a mirror for the first volume I immediately get errors (see below). Is there something I special I need to do to add a mirror for a volume other than the last one? More info: I opened Disk Management, right-clicked on the first volume on the existing disk, went to Add Mirror, and selected the new disk. The first time I did this I was prompted to convert the new disk to a Dynamic Disk, which I approved. Subsequently I got a message: The operation failed to complete because the Disk Management console view is not up-to-date. Refresh the view by using the refresh task. If the problem persists close the Disk Management console, then restart Disk Management or restart the computer. I've refreshed disk management, restarted the computer, and converted the new disk to basic and back to dynamic, but I still get that error message. Looking around for suggestions of a workaround, I saw a suggestion to use the diskpart command line tool. Running diskpart from the Start Menu as Administrator, I did select volume 2 (the first volume I want to mirror) and then add disk 2 (the new disk), and received a somewhat similar error: Virtual Disk Service error: The disk's extent information is corrupted. DiskPart has referenced an object which is not up-to-date. Refresh the object by using the RESCAN command. If the problem persists exit DiskPart, then restart DiskPart or restart the computer. A rescan appears to be successful: DISKPART> select disk 2 Disk 2 is now the selected disk. DISKPART> rescan Please wait while DiskPart scans your configuration... DiskPart has finished scanning your configuration. but attempting to add the mirror again resulted in the same error. The only similar report I found online was this: http://www.sevenforums.com/hardware-devices/335780-unable-mirror-all-but-last-partition-drive.html Based on that I attempted to mirror the last volume on the disk to the new disk using diskpart, and that started successfully -- it is currently resynchronizing. More Background: In the course of dealing with a failing 3TB hard drive, I bought a replacement 4TB drive and installed it, then copied the partitions from the failing drive to it using Minitool Partition Wizard Home, and then removed the failing drive and was up and running again normally. Now I've received a warranty replacement for the failing drive, and installed it, and now I'm attempting to mirror my partitions to it.

• Apache + PHP in paths with accented letters

  - by Álvaro G. Vicario

  I'm not able to run a PHP enabled web site under Apache on Windows XP if the path to DOCUMENT_ROOT contains accented letters. I'm not referring to the script file names themselves but to any folder in the path components. I have this virtual host definition: <VirtualHost *:80> ServerName foo.local DocumentRoot "E:/gonzález/sites/foo" ErrorLog logs/foo.local-error.log CustomLog logs/foo.local-access.log combined <Directory "E:/gonzález/sites/foo"> AllowOverride All Options Indexes FollowSymLinks Order allow,deny Allow from all </Directory> </VirtualHost> If I save the file in ANSI I get a syntax error: DocumentRoot must be a directory If I save the file in Unicode I get another syntax error: Invalid command '\xff\xfe#', perhaps misspelled or defined by a module not included in the server configuration (looks like it's complaining about the BOM) If I save the file in BOM-less UTF-8 Apache works fine and it serves static files with no apparent issue... ... however, PHP complaints when loading any *.php file (even an empty one): Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0 Fatal error: Unknown: Failed opening required 'E:/gonzález/sites/foo/vacio.php' (include_path='.;C:\Archivos de programa\PHP\pear') in Unknown on line 0 I decided to try the 8+3 short name of the directory (just a test, I don't want to use such a workaround): <VirtualHost *:80> ServerName foo.local DocumentRoot "E:/GONZLE~1/sites/foo" ErrorLog logs/foo.local-error.log CustomLog logs/foo.local-access.log combined <Directory "E:/GONZLE~1/sites/foo"> AllowOverride All Options Indexes FollowSymLinks Order allow,deny Allow from all </Directory> </VirtualHost> But I get the same behaviour: Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0 Fatal error: Unknown: Failed opening required 'E:/gonzález/sites/foo/vacio.php' (include_path='.;C:\Archivos de programa\PHP\pear') in Unknown on line 0 While there're obvious workarounds (use plain ASCII in all directory names or create NTFS junctions to hide actual names) I can't believe that this cannot be done. Do you have more information about the subject? My specs include 32 bit Windows XP Professional SP3, Apache/2.2.13 and PHP/5.2.11 running as Apache module (but I've noticed the same issue in another box with Windows Vista and PHP/5.3.1).

• User given a login prompt when closing Word documents after viewing them in IE7

  - by Martin Owen

  When using IE7 to view Word documents on our CRM system (an ASP.NET 2.0 application running on Windows Server 2003 and IIS 6 and using Windows authenticaton) I'm finding that a prompt appears when the user closes the document. The Word document is originally opened by clicking a link in the CRM system. Are there permissions that I can set on the folder containing the Word documents to prevent this prompt? I've already tried only allowing the Read permission for the Users group (I've left Administrators with Full Control.) If there's another solution to this without using permissions please let me know. UPDATE: I ran Fiddler as suggested by JD and here is the output from the two responses after the request for the document. The first seems to be a DAV response and the second is the authentication request. How do I prevent the DAV response and just return the .doc on the server? OPTIONS / HTTP/1.1 Translate: f User-Agent: Microsoft Data Access Internet Publishing Provider Protocol Discovery Host: <REMOVED> Content-Length: 0 Connection: Keep-Alive Pragma: no-cache X-NovINet: v1.2 HTTP/1.1 200 OK Date: Thu, 18 Feb 2010 13:37:36 GMT Server: Microsoft-IIS/6.0 X-Powered-By: ASP.NET MS-Author-Via: DAV Content-Length: 0 Accept-Ranges: none DASL: <DAV:sql> DAV: 1, 2 Public: OPTIONS, TRACE, GET, HEAD, DELETE, PUT, POST, COPY, MOVE, MKCOL, PROPFIND, PROPPATCH, LOCK, UNLOCK, SEARCH Allow: OPTIONS, TRACE, GET, HEAD, COPY, PROPFIND, SEARCH, LOCK, UNLOCK Cache-Control: private ------------------------------------------------------------------ OPTIONS /docs/ZONE%20100-105.doc HTTP/1.1 Translate: f User-Agent: Microsoft Data Access Internet Publishing Provider Protocol Discovery Host: <REMOVED> Content-Length: 0 Connection: Keep-Alive Pragma: no-cache X-NovINet: v1.2 HTTP/1.1 401 Unauthorized Content-Length: 83 Content-Type: text/html Server: Microsoft-IIS/6.0 WWW-Authenticate: Basic realm="<REMOVED>" X-Powered-By: ASP.NET Date: Thu, 18 Feb 2010 13:37:36 GMT ------------------------------------------------------------------ UPDATE 2: I found a potential workaround for the problem via this post: http://forums.iis.net/p/1149091/1868317.aspx. I moved all of the documents that are being requested into a folder outside of the web root, and created a virtual directory for it (also outside of the web root). When I followed a link to one of the documents in IE and then closed the document I wasn't presented with a login prompt. I should point out that I'm not using FPSE, unlike the person in the forum post. Ideally I don't want to have to put the documents in a separate virtual directory, but this is the simplest solution I've found so far.

• Blank displays after inactivity, mouse cursor not showing up

  - by Mike Christiansen

  I have a Windows 7 Enterprise x86 machine that is exhibiting some strange problems. After some inactivity (it varies how long it takes), when I come back to my computer, both of my monitors are black. The monitors are on, with a black display. Moving the mouse and pressing keys on the keyboard do not work. This happens at least once a day. When I first encountered the issue, I performed a hard shutdown and restarted the computer. About 10% of the time when I did this, the resolutions on my monitors were messed up. The native resolution on the primary monitor is 1600x900, and the native on my secondary is 1440x900. None of the widescreen resolutions would be present in the display properties. I had 800x600, 1024x768, and 1280x1024. As a workaround to this issue, I've found that if I plug in my secondary monitor as the primary monitor, and leave the secondary unplugged, then Windows will start in 1024x768 on the secondary. Then, I can use Windows 7's "Detect" feature and it finds the 1440x900 resolution, and sets it. Then I have to connect the primary monitor to the secondary port and set it as the primary. Then I can switch the two cables, putting the primary into the primary, the secondary into the secondary. Then use the "Detect" feature again, and it finds the correct resolutions. Some time after performing the above, I discovered that when the screens were blanked, I could simply press "Control+Alt+Delete", type in my password, and everything comes up fine - except my mouse cursor. All applications and features work as intended, except there is no mouse cursor (the mouse actually works though...). I have the "Show location of pointer when I press CTRL key" option selected, so I can press CTRL and use my mouse as normal - but I have no actual cursor. When the computer is in this state, UAC is also not functional. Whenever a UAC prompt appears, the screens go black (the original symptoms) and I have to press Escape to exit UAC. Because of the above symptoms (the UAC black screen thing, etc) I beleive winlogon.exe may be the culprit. However, I have no idea how to fix it. I am unable to restart winlogon.exe due to the problems I am having with winlogon.exe (the UAC black screen) Looking for any ideas.... More information Windows 7 x86 Enterprise Domain environment (I have a secondary account with administrator rights) Dell Optiplex 960 Cannot perform "optional" windows updates due to an activation issue (I am testing a windows 7 image, and an activation infrastructure has not been created yet. However, this issue was happening before I was unable to perform windows update, and windows was up to date at the time Updated video card driver (as an attempt to fixing the resolution issue) Disabled all power saving options Please let me know what else you need to help me solve this issue! Thanks in advance, Mike

• Best way to handle PHP sessions across Apache vhost wildcard domains

  - by joshholat

  I'm currently running a site that allows users to use custom domains (i.e. so instead of mysite.com/myaccount, they could have myaccount.com). They just change the A record of their domain and we then use a wildcard vhost on Apache to catch the requests from the custom domains. The setup is basically as seen below. The first vhost catches the mysite.com/myaccount requests and the second would be used for myaccount.com. As you can see, they have the exact same path and php cookie_domain. I've noticed some weird behavior surrounding the line below "#The line below me". When active, the custom domains get a new session_id every page load (that isn't the same as the non-custom domain session). However, when I comment that line out, the user keeps the same session_id on each page load, but that session_id is not the same as the one they'd see on a non-custom domain site either despite being completely on the same server. There is a sort of "hack" workaround involving redirecting the user to mysite.com/myaccount, getting the session ID, redirecting back to myaccount.com, and then using that ID on the myaccount.com. But that can get kind of messy (i.e. if the user logs out of mysite.com/myaccount, how does myaccount.com know?). For what it's worth, I'm using a database to manage the sessions (i.e. so there's no issues with being on different servers, etc, but that's irrelevant since we only use one server to handle all requests currently anyways). I'm fairly certain it is related to some sort of CSRF browser protection thing, but shouldn't it be smart enough to know it's on the same server? Note: These are subdomains, they're separate domains entirely (but on the same server). <VirtualHost *:80> DocumentRoot "/opt/local/www/mysite.com" ServerName mysite.local ErrorLog "/opt/local/apache2/logs/mysite.com-error.log" CustomLog "/opt/local/apache2/logs/mysite.com-access.log" common <Directory "/opt/local/www/mysite.com"> AllowOverride All #php_value session.save_path "/opt/local/www/mysite.com/sessions" php_value session.cookie_domain "mysite.local" php_value auto_prepend_file "/opt/local/www/mysite.com/core.php" </Directory> </VirtualHost> #Wildcard (custom domain) vhost <VirtualHost *:80> DocumentRoot "/opt/local/www/mysite.com" ServerName default ServerAlias * ErrorLog "/opt/local/apache2/logs/mysite.com-error.log" CustomLog "/opt/local/apache2/logs/mysite.com-access.log" common <Directory "/opt/local/www/mysite.com"> AllowOverride All #php_value session.save_path "/opt/local/www/mysite.com/sessions" # The line below me php_value session.cookie_domain "mysite.local" php_value auto_prepend_file "/opt/local/www/mysite.com/core.php" </Directory> </VirtualHost>

• Spaces and Parenthesis in windows PATH variable screws up batch files.

  - by NoName

  So, my path variable (System-Adv Settings-Env Vars-System-PATH) is set to: C:\Python26\Lib\site-packages\PyQt4\bin; %SystemRoot%\system32; %SystemRoot%; %SystemRoot%\System32\Wbem; %SYSTEMROOT%\System32\WindowsPowerShell\v1.0\; C:\Python26\; C:\Python26\Scripts\; C:\cygwin\bin; "C:\PathWithSpaces\What_is_this_bullshit"; "C:\PathWithSpaces 1.5\What_is_this_bullshit_1.5"; "C:\PathWithSpaces (2.0)\What_is_this_bullshit_2.0"; "C:\Program Files (x86)\IronPython 2.6"; "C:\Program Files (x86)\Subversion\bin"; "C:\Program Files (x86)\Git\cmd"; "C:\Program Files (x86)\PuTTY"; "C:\Program Files (x86)\Mercurial"; Z:\droid\android-sdk-windows\tools; Although, obviously, without the newlines. Notice the lines containing PathWithSpaces - the first has no spaces, the second has a space, and the third has a space followed by a parenthesis. Now, notice the output of this batch file: C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\>vcvars32.bat C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin>"C:\Program Files (x86 )\Microsoft Visual Studio 9.0\Common7\Tools\vsvars32.bat" Setting environment for using Microsoft Visual Studio 2008 x86 tools. \What_is_this_bullshit_2.0";"C:\Program was unexpected at this time.

How can I fix this? I'll probably resort to a junction point to let my tools still work as workaround, but if you have any insight into this, please let me know :)

• Anyone else experiencing high rates of Linux server crashes during a leap second day?

  - by Bron Gondwana

  POSTMORTEM Anticlimax: only thing that died was my VPN (openvpn) link to the cluster, so there was an exciting few seconds while it re-established. Everything else was fine. Starting back ntp everywhere. If you look at Marco's blog at http://my.opera.com/marcomarongiu/blog/2012/06/01/an-humble-attempt-to-work-around-the-leap-second - he has a solution for phasing the time change over 24 hours using ntpd -x to avoid the 1 second skip. Give that a go if it matters to you. For the systems I run, the jump isn't a problem. Just today, Sat June 30th - starting soon after the start of the day GMT. We've had a handful of blades in different datacentres as managed by different teams all go dark - not responding to pings, screen blank. They're all running Debian Squeeze - with everything from stock kernel to custom 3.2.21 builds. Most are Dell M610 blades, but I've also just lost a Dell R510 and other departments have lost machines from other vendors too. There was also an older IBM x3550 which crashed and which I thought might be unrelated, but now I'm wondering. The one crash which I did get a screen dump from said: [3161000.864001] BUG: spinlock lockup on CPU#1, ntpd/3358 [3161000.864001] lock: ffff88083fc0d740, .magic: dead4ead, .owner: imapd/24737, .owner_cpu: 0 Unfortunately the blades all supposedly had kdump configured, but they died so hard that kdump didn't trigger - and they had console blanking turned on. I've disabled console blanking now, so fingers crossed I'll have more information after the next crash. Just want to know if it's a common thread or "just us". It's really odd that they're different units in different datacentres bought at different times and run by different admins (I run the FastMail.FM ones)... and now even different vendor hardware. Most of the machines which crashed had been up for weeks/months and were running 3.1 or 3.2 series kernels. The most recent crash was a machine which had only been up about 6 hours running 3.2.21. THE WORKAROUND Ok people, here's how I worked around it. disabled ntp: /etc/init.d/ntp stop created http://linux.brong.fastmail.fm/2012-06-30/fixtime.pl (code stolen from Marco, see blog posts in comments) ran fixtime.pl without an argument to see that there was a leap second set ran fixtime.pl with an argument to remove the leap second NOTE: depends on adjtimex. I've put a copy of the squeeze adjtimex binary at http://linux.brong.fastmail.fm/2012-06-30/adjtimex - it will run without dependencies on a squeeze 64 bit system. If you put it in the same directory as fixtime.pl, it will be used if the system one isn't present. Obviously if you don't have squeeze 64 bit... find your own. I'm going to start ntp again tomorrow. As an anonymous user suggested - an alternative to running adjtimex is to just set the time yourself, which will presumably also clear the leapsecond counter.

• Cannot Send Item error in Outlook - permissions to registry?

  - by Tim Alexander

  The issue I am trying to solve is to do with users getting a Cannot Send Item error in Outlook 2007 connecting to Exchange 2007. Basically if there is an image in the email (either one they have pasted in or one from another email in the chain) they get a "Cannot Send Item" error. Initially thought it was a citrix issue but users get it when they RDP to a server as well. Changing the message to Rich Text works 80% of the time but I do not think this is a solution but more of a temporary workaround. After some troubleshooting we found that the error can be fixed by adding the user as a member of the local power users group. of course this is not really a fix. My thoughts were that the ability of a power user to add/remove software may give them more access to the registry which might allow them to get round a restriction that is in place for a normal user. I have tried going through a procmon but the wealth of information is confusing. It initially looked like it may be an Outlook 2007 email security setting but this does not change between power user and normal user (set to 1 in the registry, "Use the security setting from Outlook Security Settings Public Folders"). I am struggling to fine tune my troubleshooting to work out exactly what is blocking it. Has anyone had an experience with an error similar to this? Or are there any tips for trying to track down issues via procmon as I must admit my approach seems somewhat lacking :) EDIT: So I have trawled through the two logs we have from process monitor (one as a power user and one a normal user). annoyingly I can find no obvious difference where something is denied access. There are more access denied events in the normal user log but these are quickly followed by sucessful entries to the same path fractions of a second later. The only thing that does stand out is an access denied to HKCR.html. This does not even appear in the power user version of the log. From what I understand this helps determine the default browser which ties in nicely with the fact that 9 out of 10 times you can send the message as Rich Text. EDIT: Looks like KB2509470 was causing the issue. Not really sure why but when I can work out what it does and why it causes the problem will post here unless anyone beats me to it!

• Thinkpad speaker turns mute - Linux Codec issue?

  - by Curlew

  At some point a few days ago the speakers on my Lenovo Thinkpad T410 (Model number: 2537A11) suddenly stopped working randomly. This error happens every time I watch a video or listen to a music file. The sound just abruptly stops. At the moment, I can't produce a single sound no matter what I do. I am using Debian GNU/Linux on this laptop and there doesn't appear to be anything else wrong (the fan is working, no abnormal heat (staying around ~40°C), no other obvious errors or problems). Here is the output of a nice program someone pointed me to: martin@martin:~/Downloads$ sudo python run.py --monitor Using temporary directory: /dev/shm/hda-analyzer You may remove this directory when finished or if you like to download the most recent copy of hda-analyzer tool.

Suggest a bigger bdl_pos_adj. I changed the bdl_pos_adj to various numbers (-1, 0, 64, 1024) and either there is no change at all or dmesg reports that the adjustment is too big. I wonder if this bdl_pos_adj is the real reason for the error. Here is my hardware information provided by alsa-info.sh website. Okay, i did some serious testing and even installed Windows and now i officially conclude that this is a hard-ware related issue with my Laptop speakers. Reason: The error occurs in my installed Debian Linux, an Ubuntu Live distribution and Windows XP No error-message appears in all of the OS. The sound just keeps running and i can't hear a thing. I tested different setups, including OSS, ALSA and the pulseaudio server on top If i use my new usb-headphones i can hear sound all the time without any sudden silences. So obviously, although hard to believe, my laptop speakers are not okay (never heard of similar cases). I'll award the bounty to anyone who can point me to good tutorials or the procedure how to exchange my T410 speakers (i still have warranty. The laptop was bought in Germany, but now i am in Denmark). Or to someone who can explain me the output from hda-analyzer (big log above).

• Can Remote Desktop Services be deployed and administered by PowerShell alone, without a Domain in WIndows Server 2012 and 2012 R2?

  - by Warren P

  Windows Server 2008 R2 allowed deployment of Terminal Server (Remote Desktop Services) without a domain, and without any insistence on domains. This was very useful, especially for standalone virtual or cloud deployments of a server that is managed remotely for a remote client who has no need or desire for any ActiveDirectory or Domain features. This has become steadily more and more difficult as Microsoft restricts its technologies further and further in each Windows release. With Windows Server 2012, configuring licensing for Remote Desktop Services, is more difficult when not on a domain, but possible still. With Windows Server 2012 R2 (at least in the preview) the barriers are now severe: The Add/Remove Roles and Features wizard in Windows Server 2012 R2 has a special RDS deployment mode that has a rule that says if you aren't on a domain you can't deploy. It tells you to create or join a domain first. This of course comes in direct conflict with the fact that an Active Directory domain controller should not be the same machine as a terminal server machine. So Microsoft's technology is not such much a Cloud Operating System as a Cluster of Unwanted Nodes, needed to support the one machine I actually WANT to deploy. This is gross, and so I am trying to find a workaround. However if you skip that wizard and just go check the checkboxes in the main Roles/Features wizard, you can deploy the features, but the UI is not there to configure them, and when you go back to the RDS configuration page on the roles wizard, you get a message saying you can not administer your Remote Desktop Services system when you are logged in as a Local-Computer Administrator, because although you have all admin priveleges you could have (in your workgroup based system), the RDS configuration UI will not accept those credentials and let you continue. My question in brief is, can I still somehow, obtain the following end result: I need to allow 10-20 users per system to have an RDS (TS) session. I do not need any of the fancy pants RDS options, unless Microsoft somehow depends on those features being present. I believe I need the "RDS Session Host" as this is the guts of "Terminal Server". Microsoft says it is "full Windows desktop for Remote Desktop Services client. I need to configure licensing so that the Grace Period does not expire leaving my RDS non functional, so this probably means I need a way to configure TS CALs. If all of the above could technically be done with the judicious use of the PowerShell, I am prepared to even consider developing all the PowerShell scripts I would need to do the above. I'm not asking someone to write that for me. What I'm asking is, does anyone know if there is a technical impediment to what I want to do above, other than the deliberate crippling of the 2012 R2 UI for Workgroup users? Would the underlying technologies all still work if I manipulate and control them from a PowerShell script? Obviously a 1 word Yes or No answer isn't that useful to anyone, so the question is really, yes or no, and why? In the case the answer is Yes, then how.

• Windows Server 2008 R2 Firewall - Interface specific rules

  - by Mehmet Ergut

  I'm trying to define per interface rules, much like it was in Server 2003. We will be replacing our old 2003 server with a new 2008 R2 server. The server runs IIS and SQL Server. It's a dedicated server at the hosting company. We use a OpenVPN connection from the office to access SQL server, RDesktop, FTP and other administrative services. Only http and ssh is listening on the public interface. On the old server running 2003, I was able to define global rules for http and ssh, and allow other services only on the vpn interface. I can't find a way to do the same on 2008 R2. I understand that there is the Network Location Awareness service, firewall rules are applied according to the current network location. But I don't understand the purpose of this on a server. The only close solution I found is to set the scope on the firewall rule and restrict remote ip addresses to the private subnet of the office. But the ports will still be listening on the public interface. So how can I restrict a firewall rule to the connections coming from the vpn interface ? A note on this page states that scoping a rule to an interface does not exist anymore: In earlier versions of Windows, many of these command accepted a parameter called interface. This parameter is not supported in the firewall context in Windows Vista or later versions of Windows. I can't believe that they simply decided to remove a core firewall functionality that every firewall has. There must be a way to restrict a rule to an interface. Any ideas ? I'm still unable to find an adequate solution to my problem. So for now, my workaround is this: Administrative services listen on VPN IP address Firewall rules restrict the scope to the local IP address of VPN Public services listen on all interfaces, no scope restriction on firewall rules This is not optimal, if I change the IP address of the VPN, I need to edit the firewall rules too. It won't be the case if the rules were bound to the interface.

  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...

• How to auto advance a PowerPoint slide after an exit animation is over?

  - by joooc

  PowerPoint entrance animation set up with "Start: With Previous" starts right when a new slide is advanced. However, if you set up an exit animation in the same way, it doesn't start with a slide ending sequence. Instead, the "Start: On Click" trigger needs to be used and after your exit animation is over you still need one extra click just to advance to the next slide. Workarounds to this are obvious: create a duplicate slide, make your ending animations from the original slide being your starting animations on the duplicate slide and let them be followed with whatever you want or create a transition slide with those ending animations only and set up "Change Advance slide - Automatically after - [the time it takes your animations to finish]". These workarounds will make it work for your audience, visually. However, it has an impact on slide numbers you might need to adjust accordingly and/or duplicate content changes. If you are the only one creating and using your presentation, this might be just fine. But if you are creating a presentation in collaborative mode with three other people and don't even know who will be the presenter at the end, you can mess things up. Let's be specific: most of my slides have 0.2s fly in entrance animation applied to blocks of content coming from right, bottom or left. Advancing to the next slide I want them to fly out in another 0.2s exit animation being followed by new slide 0.2s fly in entrance animation of the new blocks. The swapping of the blocks should be triggered while advancing to the next slide, as usually. As mentioned, I'm not able to achieve this without one extra click between the slides. I wrote a VBA script that should start together with an exit animation and will auto advance a slide after 0.3s when the exit animation is over. That way I should get rid of those extra clicks which are needed right now. Sub nextslide() iTime = 0.3 Start = Timer While Timer < Start + iTime DoEvents Wend With SlideShowWindows(1).View .GotoSlide (ActivePresentation.SlideShowWindow.View.Slide.SlideIndex + 1) End With End Sub It works well when binded on a box, button or another object. But I can't make it run on a single click (anywhere on the slide) so that it could start together with the exit animation onclick trigger. Creating a big transparent rectangular shape over the whole slide and binding the macro on it doesn't help either. By clicking it you only get the macro running, exit animation is not triggered. Anyway, I don't want to bind the macro to any other workaround object but the slide itself. Anyone knows how to trigger a PowerPoint VBA script on slide onclick event? Anyone knows a secret setting that will make the exit animation work as expected i.e. animating right before exiting a slide while transitioning to the next one? Anyone knows how to beat this dragon? Thank you!

• FTP script needs blank line

  - by Ones and Zeroes

  I am trying to determine the reason for some FTP servers requiring a blank line in the script as follows: open server.com username ftp_commands bye Refer to blank line required after username credentials. Example from: FTP from batch file another reference to the same: http://newsgroups.derkeiler.com/Archive/Comp/comp.sys.ibm.as400.misc/2008-05/msg00227.html Also discussed here: archive.midrange.com/midrange-l/200601/msg00048.html "The behavior I'm observing is the same as if I didn't specify the password to login." with an answer referring to our same fix... archive.midrange.com/midrange-l/200601/msg00053.html and archive.midrange.com/midrange-l/200601/msg00065.html Note: It is my experience that FTP questions attract uncouth responses. Admittedly FTP is outdated, but many clients still have legacy systems, which they cannot upgrade or replace. The reason thereof should not be discussed here. The intention of this question is to invite a positive response. Please do not respond if you disagree with the above. If you have never encountered this same issue, please do not respond. I suspect this may be limited to FTP scripts executed from Windows machines, but have been told that this happens often and with many different servers. My specific interest is to understand what may cause this as I have a real world example of a production system suddenly requiring this as a workaround fix, after running for many years without issue. The server belongs to a third party who claims no change on their end. Server details unknown and cannot be determined. Any help or encouragement from someone who has come across the same, would be appreciated. ps. Sorry for the many words and references to painful responses, but I have asked similar questions on serverfault and elsewhere and unfortunately got back kneejerk responses to FTP and respondents debating the validity of the question. I would truly not ask, or re-post this question online if I had a better understanding of the issue. I know of people who have seen this issue, but don't know what causes it. I am wary that this question would again turn into another irrelevant discussion. Please, I ask very nicely: Please do not respond if you have not encountered a similar issue. FURTHER EDIT: Please do not suggest changing the product. The problem is not the blank line requirement. We know this fixes the issue. The problem is not being able to explain the reason for the blank line in the first place. Slight difference, but a critical point to note wrt the answering of this question.

• Other processes take over port 80 when restarting Apache - why, and how to solve?

  - by user72149

  I have a CentOS 5.5 server running Apache on port 80 as well as some other applications. All works fine until I for some reason need to restart the httpd process. Doing so returns: sudo /etc/init.d/httpd restart Stopping httpd: [ OK ] Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:80 (98)Address already in use: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down Unable to open logs First I thought perhaps httpd had frozen and was still running, but that was not the case. So I ran netstat to find out what was using port 80: sudo netstat -tlp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 *:7203 *:* LISTEN 24012/java tcp 0 0 localhost.localdomain:smux *:* LISTEN 3547/snmpd tcp 0 0 *:mysql *:* LISTEN 21966/mysqld tcp 0 0 *:ssh *:* LISTEN 3562/sshd tcp 0 0 *:http *:* LISTEN 3780/python26 Turns out that my python process had taken over listening to http in the instant that httpd was restarting. So, I killed python and tried starting httpd again - but ran into the same error. Netstat again: sudo netstat -tlp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 *:7203 *:* LISTEN 24012/java tcp 0 0 localhost.localdomain:smux *:* LISTEN 3547/snmpd tcp 0 0 *:mysql *:* LISTEN 21966/mysqld tcp 0 0 *:ssh *:* LISTEN 3562/sshd tcp 0 0 *:http *:* LISTEN 24012/java Now my java process had taken over listening to http. I killed that too and could then successfully restart httpd. But this is a terrible workaround. Why will these python and java processes start listening to port 80 as soon as httpd is restarted? How to solve? Two other comments. 1) Both java and python processes are started by apache from a php script. But when apache is restarted, they should not be affected. And 2) I have the same setup on two other machines running Ubuntu and there's no problem there. Any ideas? Edit: The Java process listens to port 7203 and the python process supposedly doesn't listen to any port. For some reason, they start listening to port 80 when apache is restarted. This hasn't happened before. On Ubuntu it runs fine. For some reason, on my current CentOS 5.5 machine, this problem arises.

• Non-Dom Element Event Binding with jQuery

  - by Rick Strahl

  Yesterday I had a short discussion with Dave Reed on Twitter regarding setting up fake ‘events’ on objects that are hookable. jQuery makes it real easy to bind events on DOM elements and with a little bit of extra work (that I didn’t know about) you can also set up binding to non-DOM element ‘event’ bindings. Assume for a second that you have a simple JavaScript object like this: var item = { sku: "wwhelp" , foo: function() { alert('orginal foo function'); } }; and you want to be notified when the foo function is called. You can use jQuery to bind the handler like this: $(item).bind("foo", function () { alert('foo Hook called'); } ); Binding alone won’t actually cause the handler to be triggered so when you call: item.foo(); you only get the ‘original’ message. In order to fire both the original handler and the bound event hook you have to use the .trigger() function: $(item).trigger("foo"); Now if you do the following complete sequence: var item = { sku: "wwhelp" , foo: function() { alert('orginal foo function'); } }; $(item).bind("foo", function () { alert('foo hook called'); } ); $(item).trigger("foo"); You’ll see the ‘hook’ message first followed by the ‘original’ message fired in succession. In other words, using this mechanism you can hook standard object functions and chain events to them in a way similar to the way you can do with DOM elements. The main difference is that the ‘event’ has to be explicitly triggered in order for this to happen rather than just calling the method directly. .trigger() relies on some internal logic that checks for event bindings on the object (attached via an expando property) which .trigger() searches for in its bound event list. Once the ‘event’ is found it’s called prior to execution of the original function. This is pretty useful as it allows you to create standard JavaScript objects that can act as event handlers and are effectively hookable without having to explicitly override event definitions with JavaScript function handlers. You get all the benefits of jQuery’s event methods including the ability to hook up multiple events to the same handler function and the ability to uniquely identify each specific event instance with post fix string names (ie. .bind("MyEvent.MyName") and .unbind("MyEvent.MyName") to bind MyEvent). Watch out for an .unbind() Bug Note that there appears to be a bug with .unbind() in jQuery that doesn’t reliably unbind an event and results in a elem.removeEventListener is not a function error. The following code demonstrates: var item = { sku: "wwhelp", foo: function () { alert('orginal foo function'); } }; $(item).bind("foo.first", function () { alert('foo hook called'); }); $(item).bind("foo.second", function () { alert('foo hook2 called'); }); $(item).trigger("foo"); setTimeout(function () { $(item).unbind("foo"); // $(item).unbind("foo.first"); // $(item).unbind("foo.second"); $(item).trigger("foo"); }, 3000); The setTimeout call delays the unbinding and is supposed to remove the event binding on the foo function. It fails both with the foo only value (both if assigned only as “foo” or “foo.first/second” as well as when removing both of the postfixed event handlers explicitly. Oddly the following that removes only one of the two handlers works: setTimeout(function () { //$(item).unbind("foo"); $(item).unbind("foo.first"); // $(item).unbind("foo.second"); $(item).trigger("foo"); }, 3000); this actually works which is weird as the code in unbind tries to unbind using a DOM method that doesn’t exist. <shrug> A partial workaround for unbinding all ‘foo’ events is the following: setTimeout(function () { $.event.special.foo = { teardown: function () { alert('teardown'); return true; } }; $(item).unbind("foo"); $(item).trigger("foo"); }, 3000); which is a bit cryptic to say the least but it seems to work more reliably. I can’t take credit for any of this – thanks to Dave Reed and Damien Edwards who pointed out some of these behaviors. I didn’t find any good descriptions of the process so thought it’d be good to write it down here. Hope some of you find this helpful.© Rick Strahl, West Wind Technologies, 2005-2010Posted in jQuery

• jQuery 1.4 Opacity and IE Filters

  - by Rick Strahl

  Ran into a small problem today with my client side jQuery library after switching to jQuery 1.4. I ran into a problem with a shadow plugin that I use to provide drop shadows for absolute elements – for Mozilla WebKit browsers the –moz-box-shadow and –webkit-box-shadow CSS attributes are used but for IE a manual element is created to provide the shadow that underlays the original element along with a blur filter to provide the fuzziness in the shadow. Some of the key pieces are: var vis = el.is(":visible"); if (!vis) el.show(); // must be visible to get .position var pos = el.position(); if (typeof shEl.style.filter == "string") sh.css("filter", 'progid:DXImageTransform.Microsoft.Blur(makeShadow=true, pixelradius=3, shadowOpacity=' + opt.opacity.toString() + ')'); sh.show() .css({ position: "absolute", width: el.outerWidth(), height: el.outerHeight(), opacity: opt.opacity, background: opt.color, left: pos.left + opt.offset, top: pos.top + opt.offset }); This has always worked in previous versions of jQuery, but with 1.4 the original filter no longer works. It appears that applying the opacity after the original filter wipes out the original filter. IOW, the opacity filter is not applied incrementally, but absolutely which is a real bummer. Luckily the workaround is relatively easy by just switching the order in which the opacity and filter are applied. If I apply the blur after the opacity I get my correct behavior back with both opacity: sh.show() .css({ position: "absolute", width: el.outerWidth(), height: el.outerHeight(), opacity: opt.opacity, background: opt.color, left: pos.left + opt.offset, top: pos.top + opt.offset }); if (typeof shEl.style.filter == "string") sh.css("filter", 'progid:DXImageTransform.Microsoft.Blur(makeShadow=true, pixelradius=3, shadowOpacity=' + opt.opacity.toString() + ')'); While this works this still causes problems in other areas where opacity is implicitly set in code such as for fade operations or in the case of my shadow component the style/property watcher that keeps the shadow and main object linked. Both of these may set the opacity explicitly and that is still broken as it will effectively kill the blur filter. This seems like a really strange design decision by the jQuery team, since clearly the jquery css function does the right thing for setting filters. Internally however, the opacity setting doesn’t use .css instead hardcoding the filter which given jQuery’s usual flexibility and smart code seems really inappropriate. The following is from jQuery.js 1.4: var style = elem.style || elem, set = value !== undefined; // IE uses filters for opacity if ( !jQuery.support.opacity && name === "opacity" ) { if ( set ) { // IE has trouble with opacity if it does not have layout // Force it by setting the zoom level style.zoom = 1; // Set the alpha filter to set the opacity var opacity = parseInt( value, 10 ) + "" === "NaN" ? "" : "alpha(opacity=" + value * 100 + ")"; var filter = style.filter || jQuery.curCSS( elem, "filter" ) || ""; style.filter = ralpha.test(filter) ? filter.replace(ralpha, opacity) : opacity; } return style.filter && style.filter.indexOf("opacity=") >= 0 ? (parseFloat( ropacity.exec(style.filter)[1] ) / 100) + "": ""; } You can see here that the style is explicitly set in code rather than relying on $.css() to assign the value resulting in the old filter getting wiped out. jQuery 1.32 looks a little different: // IE uses filters for opacity if ( !jQuery.support.opacity && name == "opacity" ) { if ( set ) { // IE has trouble with opacity if it does not have layout // Force it by setting the zoom level elem.zoom = 1; // Set the alpha filter to set the opacity elem.filter = (elem.filter || "").replace( /alpha\([^)]*\)/, "" ) + (parseInt( value ) + '' == "NaN" ? "" : "alpha(opacity=" + value * 100 + ")"); } return elem.filter && elem.filter.indexOf("opacity=") >= 0 ? (parseFloat( elem.filter.match(/opacity=([^)]*)/)[1] ) / 100) + '': ""; } Offhand I’m not sure why the latter works better since it too is assigning the filter. However, when checking with the IE script debugger I can see that there are actually a couple of filter tags assigned when using jQuery 1.32 but only one when I use jQuery 1.4. Note also that the jQuery 1.3 compatibility plugin for jQUery 1.4 doesn’t address this issue either.

  DropDown.zip (135.33 kb) LiveDemo Introduction In this article i am  going to explore some of the features of the ComboBox.ComboBox makes the collection visible and allows users to pick an item from the collection.After its first initialization, no matter if you bind a new datasource with fewer or more elements, the dropdown persists its original height.One workaround is the following:1. store the Properties from the original ComboBox2. delete the ComboBox removing it from its container3. create a new ComboBox and place it in the container4. recover the stores Properties5. bind the new DataSource to the newly created combobox Creating Silverlight ProjectCreate a new Silverlight 3 Project in VS 2008. Name it as ComboBoxtSample. Simple Data BindingAdd System.Windows.Control.Data reference to the Silverlight project. Silverlight UserControl Add a new page to display Bus data using DataGrid. Following shows Bus column XAML snippet:The ComboBox element represents a ComboBox control in XAML.  <ComboBox></ComboBox>ComboBox XAML        <StackPanel Orientation="Vertical">            <ComboBox Width="120" Height="30" x:Name="DaysDropDownList" DisplayMemberPath="Name">                <!--<ComboBox.ItemTemplate>                    <DataTemplate>                        <StackPanel Orientation="Horizontal">                            <TextBlock Text="{Binding Path=Name}" FontWeight="Bold"></TextBlock>                            <TextBlock Text=", "></TextBlock>                            <TextBlock Text="{Binding Path=ID}"></TextBlock>                        </StackPanel>                    </DataTemplate>                </ComboBox.ItemTemplate>-->            </ComboBox>        </StackPanel>   The following code below is an example implementation Combobox control support data binding     1 By setting the DisplayMemberPath property you can specify which data item in your data you want displayed in the ComboBox.    2 Setting the SelectedIndex allows you to specify which item in the ComboBox you want selected. Business Object public class Bus { public string Name { get; set; } public float Price { get; set; } }   Data Binding private List populatedlistBus() { listBus = new List(); listBus.Add(new Bus() {Name = "Bus 1", Price = 55f }); listBus.Add(new Bus() { Name = "Bus 2", Price = 55.7f }); listBus.Add(new Bus() { Name = "Bus 3", Price = 2f }); listBus.Add(new Bus() { Name = "Bus 4", Price = 6f }); listBus.Add(new Bus() { Name = "Bus 5", Price = 9F }); listBus.Add(new Bus() { Name = "Bus 6", Price = 10.1f }); return listBus; }   The following line of code sets the ItemsSource property of a ComboBox.

• Getting a Web Resource Url in non WebForms Applications

  - by Rick Strahl

  WebResources in ASP.NET are pretty useful feature. WebResources are resources that are embedded into a .NET assembly and can be loaded from the assembly via a special resource URL. WebForms includes a method on the ClientScriptManager (Page.ClientScript) and the ScriptManager object to retrieve URLs to these resources. For example you can do: ClientScript.GetWebResourceUrl(typeof(ControlResources), ControlResources.JQUERY_SCRIPT_RESOURCE); GetWebResourceUrl requires a type (which is used for the assembly lookup in which to find the resource) and the resource id to lookup. GetWebResourceUrl() then returns a nasty old long URL like this: WebResource.axd?d=-b6oWzgbpGb8uTaHDrCMv59VSmGhilZP5_T_B8anpGx7X-PmW_1eu1KoHDvox-XHqA1EEb-Tl2YAP3bBeebGN65tv-7-yAimtG4ZnoWH633pExpJor8Qp1aKbk-KQWSoNfRC7rQJHXVP4tC0reYzVw2&t=634533278261362212 While lately excessive resource usage has been frowned upon especially by MVC developers who tend to opt for content distributed as files, I still think that Web Resources have their place even in non-WebForms applications. Also if you have existing assemblies that include resources like scripts and common image links it sure would be nice to access them from non-WebForms pages like MVC views or even in plain old Razor Web Pages. Where's my Page object Dude? Unfortunately natively ASP.NET doesn't have a mechanism for retrieving WebResource Urls outside of the WebForms engine. It's a feature that's specifically baked into WebForms and that relies specifically on the Page HttpHandler implementation. Both Page.ClientScript (obviously) and ScriptManager rely on a hosting Page object in order to work and the various methods off these objects require control instances passed. The reason for this is that the script managers can inject scripts and links into Page content (think RegisterXXXX methods) and for that a Page instance is required. However, for many other methods - like GetWebResourceUrl() - that simply return resources or resource links the Page reference is really irrelevant. While there's a separate ClientScriptManager class, it's marked as sealed and doesn't have any public constructors so you can't create your own instance (without Reflection). Even if it did the internal constructor it does have requires a Page reference. No good… So, can we get access to a WebResourceUrl generically without running in a WebForms Page instance? We just have to create a Page instance ourselves and use it internally. There's nothing intrinsic about the use of the Page class in ClientScript, at least for retrieving resources and resource Urls so it's easy to create an instance of a Page for example in a static method. For our needs of retrieving ResourceUrls or even actually retrieving script resources we can use a canned, non-configured Page instance we create on our own. The following works just fine: public static string GetWebResourceUrl(Type type, string resource ) { Page page = new Page(); return page.ClientScript.GetWebResourceUrl(type, resource); } A slight optimization for this might be to cache the created Page instance. Page tends to be a pretty heavy object to create each time a URL is required so you might want to cache the instance: public class WebUtils { private static Page CachedPage { get { if (_CachedPage == null) _CachedPage = new Page(); return _CachedPage; } } private static Page _CachedPage; public static string GetWebResourceUrl(Type type, string resource) { return CachedPage.ClientScript.GetWebResourceUrl(type, resource); } } You can now use GetWebResourceUrl in a Razor page like this: <!DOCTYPE html> <html <head> <script src="@WebUtils.GetWebResourceUrl(typeof(ControlResources),ControlResources.JQUERY_SCRIPT_RESOURCE)"> </script> </head> <body> <div class="errordisplay"> <img src="@WebUtils.GetWebResourceUrl(typeof(ControlResources),ControlResources.WARNING_ICON_RESOURCE)" /> This is only a Test! </div> </body> </html> And voila - there you have WebResources served from a non-Page based application. WebResources may be a on the way out, but legacy apps have them embedded and for some situations, like fallback scripts and some common image resources I still like to use them. Being able to use them from non-WebForms applications should have been built into the core ASP.NETplatform IMHO, but seeing that it's not this workaround is easy enough to implement.© Rick Strahl, West Wind Technologies, 2005-2011Posted in ASP.NET  MVC   Tweet (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• Installing SharePoint 2013 on Windows 2012- standalone installation

  - by sreejukg

  In this article, I am going to share my experience while installing SharePoint 2013 on Windows 2012. This was the first time I tried SharePoint 2013. So I thought sharing the same will benefit somebody who would like to install SharePoint 2013 as a standalone installation. Standalone installation is meant for evaluation/development purposes. For production environments, you need to follow the best practices and create required service accounts. Microsoft has published the deployment guide for SharePoint 2013, you can download this from the below link. http://www.microsoft.com/en-us/download/details.aspx?id=30384 Since this is for development environment, I am not going to create any service account, I logged in to Windows 2012 as an administrator and just placed my installation DVD on the drive. When I run the setup from the DVD, the below splash screen appears. This reflects the new UI changes happening with all Microsoft based applications; the interface matches the metro style applications (Windows 8 style). As you can see the options are same as that of the SharePoint 2010 installation screen. Click on the “install software prerequisites” link to get all the prerequisites get installed. You need a valid internet connection to do this. Clicking on the install software prerequisites will bring the following dialog. Click Next, you will see the terms and conditions. Select I accept check box and click Next. The installation will start immediately. For any reason, if you stop the installation and start it later, the product preparation tool will check whether a particular component is installed and if yes, then the installation of that particular component will be skipped. If you do not have internet connection, you will face the download error as follows. At any point of failure, the error log will be available for you to review. If all OK, you will reach the below dialog, this means some components will be installed once the PC is rebooted. Be noted that the clicking on finish will not ask you for further confirmation. So make sure to save all your work before clicking on finish button. Once the server is restarted, the product preparation tool will start automatically and you will see the following dialog. Now go to the SharePoint 2013 splash page and click on “Install SharePoint Server” link. You need to enter the product key here. Enter the product key as you received and click continue. Select the Checkbox for the license agreement and click on continue button. Now you need to select the installation type. Select Stand-alone and click on “Install Now” button. A dialog will pop up that updates you with the process and progress. The installation took around 15-20 minutes with 2 GB or Ram installed in the server, seems fair. Once the installation is over, you will see the following Dialog. Make sure you select the Run the products and configuration wizard. If you miss to select the check box, you can find the products and configuration wizard from the start tiles. The products and configuration wizard will start. If you get any dialog saying some of the services will be stopped, you just accept it. Since we selected standalone installation, it will not ask for any user input, as it already knows the database to be configured. Once the configuration is over without any problems you will see the configuration successful message. Also you can find the link to central administration on the Start Screen.     Troubleshooting During my first setup process, I got the below error. System.ArgumentException: The SDDL string contains an invalid sid or a sid that cannot be translated. Parameter name: sddlForm at System.Security.AccessControl.RawSecurityDescriptor.BinaryFormFromSddlForm(String sddlForm) at System.Security.AccessControl.RawSecurityDescriptor..ctor(String sddlForm) at Microsoft.SharePoint.Win32.SPNetApi32.CreateShareSecurityDescriptor(String[] readNames, String[] changeNames, String[] fullControlNames, String& sddl) at Microsoft.SharePoint.Win32.SPNetApi32.CreateFileShare(String name, String description, String path) at Microsoft.SharePoint.Administration.SPServer.CreateFileShare(String name, String description, String path) at Microsoft.Office.Server.Search.Administration.AnalyticsAdministration.CreateAnalyticsUNCShare(String dirParentLocation, String shareName) at Microsoft.Office.Server.Search.Administration.AnalyticsAdministration.ProvisionAnalyticsShare(SearchServiceApplication serviceApplication) ………………………………………… ………………………………………… The configuration wizard displayed the error as below. The error occurred in step 8 of the configuration wizard and by the time the central administration is already provisioned. So from the start, I was able to open the central administration website, but the search service application was showing as error. I found a good blog that specifies the reason for error. http://kbdump.com/sharepoint2013-standalone-config-error-create-sample-data/ The workaround specified in the blog works fine. I think SharePoint must be provisioning Search using the Network Service account, so instead of giving permission to everyone, you could try giving permission to Network Service account(I didn’t try this yet, buy you could try and post your feedback here). In production environment you will have specific accounts that have access rights as recommended by Microsoft guidelines. Installation of SharePoint 2013 is pretty straight forward.

• Good ol fashioned debugging

  - by Tim Dexter

  I have been helping out one of our new customers over the last day or two and I have even managed to get to the bottom of their problem FTW! They use BIEE and BIP and wanted to mount a BIP report in a dashboard page, so far so good, BIP does that! Just follow the instructions in the BIEE user guide. The wrinkle is that they want to enter some fixed instruction strings into the dashboard prompts to help the user. These are added as fixed values to the prompt as the default values so they appear first. Once the user makes a selection, the default strings disappear. Its a fair requirement but the BIP report chokes Now, the BIP report had been setup with the Autorun checkbox, unchecked. I expected the BIP report to wait for the Go button to be hit but it was trying to run immediately and failing. That was the first issue. You can not stop the BIP report from trying to run in a dashboard. Even if the Autorun is turned off, it seems that dashboard still makes the request to BIP to run the report. Rather than BIP refusing because its waiting for input it goes ahead anyway, I guess the mechanism does not check the autorun flag when the request is coming from the dashboard. It appears that between BIEE and BIP, they collectively ignore the autorun flag. A bug? might be, at least an enhancement request. With that in mind, how could we get BIP to not at least not fail? This fact was stumping me on the parameter error, if the autorun flag was being respected then why was BIP complaining about the parameter values it should not even be doing anything until the Go button is clicked. I now knew that the autorun flag was being ignored, it was a simple case of putting BIP into debug mode. I use the OC4J server on my laptop so debug msgs are routed through the dos box used to start the OC4J container. When I changed a value on the dashboard prompt I spotted some debug text rushing by that subsequently disappeared from the log once the operation was complete. Another bug? I needed to catch that text as it went by, using the print screen function with some software to grab multiple screens as the log appeared and then disappeared. The upshot is that when you change the dashboard prompt value, BIP validates the value against its own LOVs, if its not in the list then it throws the error. Because 'Fill this first' and 'Fill this second' ie fixed strings from the dashboard prompts, are not in the LOV lists and because the report is auto running as soon as the dashboard page is brought up, the report complains about invalid parameters. To get around this, I needed to get the strings into the LOVs. Easily done with a UNION clause: select 'Fill this first' from SH.Products Products UNION select Products."Prod Category" as "Prod Category" from SH.Products Products Now when BIP wants to validate the prompt value, the LOV query fires and finds the fixed string -> No Error. No data, but definitely no errors :0) If users do run with the fixed values, you can capture that in the template. If there is no data in the report, either the fixed values were used or the parameters selected resulted in no rows. You can capture this in the template and display something like. 'Either your parameter values resulted in no data or you have not changed the default values' Thats the upside, the downside is that if your users run the report in the BP UI they re going to see the fixed strings. You could alleviate that by having BIP display the fixed strings in top of its parameter drop boxes (just set them as the default value for the parameter.) But they will not disappear like they do in the dashboard prompts, see below. If the expected autorun behaviour worked ie wait for the Go button, then we would not have to workaround it but for now, its a pretty good solution. It was an enjoyable hour or so for me, took me back to my developer daze, when we used to race each other for the most number of bug fixes. I used to run a distant 2nd behind 'Bugmeister Chen Hu' but led the chasing pack by a reasonable distance.

• $.fadeTo/fadeOut() operations on Table Rows in IE fail

  - by Rick Strahl

  Here’s a a small problem that one of customers ran into a few days ago: He was playing around with some of the sample code I’ve put out for one of my simple jQuery demos which deals with providing a simple pulse behavior plug-in: $.fn.pulse = function(time) { if (!time) time = 2000; // *** this == jQuery object that contains selections $(this).fadeTo(time, 0.20, function() { $(this).fadeTo(time, 1); }); return this; } it’s a very simplistic plug-in and it works fine for simple pulse animations. However he ran into a problem where it didn’t work when working with tables – specifically pulsing a table row in Internet Explorer. Works fine in FireFox and Chrome, but IE not so much. It also works just fine in IE as long as you don’t try it on tables or table rows specifically. Applying against something like this (an ASP.NET GridView): var sel = $("#gdEntries>tbody>tr") .not(":first-child") // no header .not(":last-child") // no footer .filter(":even") .addClass("gridalternate"); // *** Demonstrate simple plugin sel.pulse(2000); fails in IE. No pulsing happens in any version of IE. After some additional experimentation with single rows and various ways of selecting each and still failing, I’ve come to the conclusion that the various fade operations in jQuery simply won’t work correctly in IE (any version). So even something as ‘elemental’ as this: var el = $("#gdEntries>tbody>tr").get(0);$(el).fadeOut(2000); is not working correctly. The item will stick around for 2 seconds and then magically disappear. Likewise: sel.hide().fadeIn(5000); also doesn’t fade in although the items become immediately visible in IE. Go figure that behavior out. Thanks to a tweet from red_square and a link he provided here is a grid that explains what works and doesn’t in IE (and most last gen browsers) regarding opacity: http://www.quirksmode.org/js/opacity.html It appears from this link that table and row elements can’t be made opaque, but td elements can. This means for the row selections I can force each of the td elements to be selected and then pulse all of those. Once you have the rows it’s easy to explicitly select all the columns in those rows with .find(“td”). Aha the following actually works: var sel = $("#gdEntries>tbody>tr") .not(":first-child") // no header .not(":last-child") // no footer .filter(":even") .addClass("gridalternate"); // *** Demonstrate simple plugin sel.find("td").pulse(2000); A little unintuitive that, but it works. Stay away from <table> and <tr> Fades The moral of the story is – stay away from TR, TH and TABLE fades and opacity. If you have to do it on tables use the columns instead and if necessary use .find(“td”) on your row(s) selector to grab all the columns. I’ve been surprised by this uhm relevation, since I use fadeOut in almost every one of my applications for deletion of items and row deletions from grids are not uncommon especially in older apps. But it turns out that fadeOut actually works in terms of behavior: It removes the item when the timeout’s done and because the fade is relatively short lived and I don’t extensively test IE code any more I just never noticed that the fade wasn’t happening. Note – this behavior or rather lack thereof appears to be specific to table table,tr,th elements. I see no problems with other elements like <div> and <li> items. Chalk this one up to another of IE’s shortcomings. Incidentally I’m not the only one who has failed to address this in my simplistic plug-in: The jquery-ui pulsate effect also fails on the table rows in the same way. sel.effect("pulsate", { times: 3 }, 2000); and it also works with the same workaround. If you’re already using jquery-ui definitely use this version of the plugin which provides a few more options… Bottom line: be careful with table based fade operations and remember that if you do need to fade – fade on columns.© Rick Strahl, West Wind Technologies, 2005-2010Posted in jQuery

• Workarounds for supporting MVVM in the Silverlight TreeView Control

  - by cibrax

  MVVM (Model-View-ViewModel) is the pattern that you will typically choose for building testable user interfaces either in WPF or Silverlight. This pattern basically relies on the data binding support in those two technologies for mapping an existing model class (the view model) to the different parts of the UI or view. Unfortunately, MVVM was not threated as first citizen for some of controls released out of the box in the Silverlight runtime or the Silverlight toolkit. That means that using data binding for implementing MVVM is not always something trivial and usually requires some customization in the existing controls. In ran into different problems myself trying to fully support data binding in controls like the tree view or the context menu or things like drag & drop.  For that reason, I decided to write this post to show how the tree view control or the tree view items can be customized to support data binding in many of its properties. In first place, you will typically use a tree view for showing hierarchical data so the view model somehow must reflect that hierarchy. An easy way to implement hierarchy in a model is to use a base item element like this one, public abstract class TreeItemModel { public abstract IEnumerable<TreeItemModel> Children; } You can later derive your concrete model classes from that base class. For example, public class CustomerModel { public string FullName { get; set; } public string Address { get; set; } public IEnumerable<OrderModel> Orders { get; set; } }   public class CustomerTreeItemModel : TreeItemModel { public CustomerTreeItemModel(CustomerModel customer) { }   public override IEnumerable<TreeItemModel> Children { get { // Return orders } } } The Children property in the CustomerTreeItem model implementation can return for instance an ObservableCollection<TreeItemModel> with the orders, so the tree view will automatically subscribe to all the changes in the collection. You can bind this model to the tree view control in the UI by using a Hierarchical data template. <e:TreeView x:Name="TreeView" ItemsSource="{Binding Customers}"> <e:TreeView.ItemTemplate> <sdk:HierarchicalDataTemplate ItemsSource="{Binding Children}"> <!-- TEMPLATE --> </sdk:HierarchicalDataTemplate> </e:TreeView.ItemTemplate> </e:TreeView> An interesting behavior with the Children property and the Hierarchical data template is that the Children property is only invoked before the expansion, so you can use lazy load at this point (The tree view control will not expand the whole tree in the first expansion). The problem with using MVVM in this control is that you can not bind properties in model with specific properties of the TreeView item such as IsSelected or IsExpanded. Here is where you need to customize the existing tree view control to support data binding in tree items. public class CustomTreeView : TreeView { public CustomTreeView() { }   protected override DependencyObject GetContainerForItemOverride() { CustomTreeViewItem tvi = new CustomTreeViewItem(); Binding expandedBinding = new Binding("IsExpanded"); expandedBinding.Mode = BindingMode.TwoWay; tvi.SetBinding(CustomTreeViewItem.IsExpandedProperty, expandedBinding); Binding selectedBinding = new Binding("IsSelected"); selectedBinding.Mode = BindingMode.TwoWay; tvi.SetBinding(CustomTreeViewItem.IsSelectedProperty, selectedBinding); return tvi; } }   public class CustomTreeViewItem : TreeViewItem { public CustomTreeViewItem() { }   protected override DependencyObject GetContainerForItemOverride() { CustomTreeViewItem tvi = new CustomTreeViewItem(); Binding expandedBinding = new Binding("IsExpanded"); expandedBinding.Mode = BindingMode.TwoWay; tvi.SetBinding(CustomTreeViewItem.IsExpandedProperty, expandedBinding); Binding selectedBinding = new Binding("IsSelected"); selectedBinding.Mode = BindingMode.TwoWay; tvi.SetBinding(CustomTreeViewItem.IsSelectedProperty, selectedBinding); return tvi; } } You basically need to derive the TreeView and TreeViewItem controls to manually add a binding for the properties you need. In the example above, I am adding a binding for the “IsExpanded” and “IsSelected” properties in the items. The model for the tree items now needs to be extended to support those properties as well, public abstract class TreeItemModel : INotifyPropertyChanged { bool isExpanded = false; bool isSelected = false;   public abstract IEnumerable<TreeItemModel> Children { get; }   public bool IsExpanded { get { return isExpanded; } set { isExpanded = value; if (PropertyChanged != null) PropertyChanged(this, new PropertyChangedEventArgs("IsExpanded")); } }   public bool IsSelected { get { return isSelected; } set { isSelected = value; if (PropertyChanged != null) PropertyChanged(this, new PropertyChangedEventArgs("IsSelected")); } }   public event PropertyChangedEventHandler PropertyChanged; } However, as soon as you use this custom tree view control, you lose all the automatic styles from the built-in toolkit themes because they are tied to the control type (TreeView in this case).  The only ugly workaround I found so far for this problem is to copy the styles from the Toolkit source code and reuse them in the application.

• Context Issue in ASP.NET MVC 3 Unobtrusive Ajax

  - by imran_ku07

      Introduction:          One of the coolest feature you can find in ASP.NET MVC 3 is Unobtrusive Ajax and Unobtrusive Client Validation which separates the javaScript behavior and functionality from the contents of a web page. If you are migrating your ASP.NET MVC 2 (or 1) application to ASP.NET MVC 3 and leveraging the Unobtrusive Ajax feature then you will find that the this context in the callback function is not the same as in ASP.NET MVC 2(or 1). In this article, I will show you the issue and a simple solution.       Description:           The easiest way to understand the issue is to start with an example. Create an ASP.NET MVC 3 application. Then add the following javascript file references inside your page,   <script src="@Url.Content("~/Scripts/MicrosoftAjax.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/MicrosoftMvcAjax.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>             Then add the following lines into your view,   @Ajax.ActionLink("About", "About", new AjaxOptions { OnSuccess = "Success" }) <script type="text/javascript"> function Success(data) { alert(this.innerHTML) } </script>              Next, disable Unobtrusive Ajax feature from web.config,   <add key="UnobtrusiveJavaScriptEnabled" value="false"/>              Then run your application and click the About link, you will see the alert window with "About" message on the screen. This shows that the this context in the callback function is the element which is clicked. Now, let's see what will happen when we leverage Unobtrusive Ajax feature. Now enable Unobtrusive Ajax feature from web.config,     <add key="UnobtrusiveJavaScriptEnabled" value="true"/>              Then run your application again and click the About link again, this time you will see the alert window with "undefined" message on the screen. This shows that the this context in the callback function is not the element which is clicked. Here, this context in the callback function is the Ajax settings object provided by jQuery. This may not be desirable because your callback function may need the this context as the element which triggers the Ajax request. The easiest way to make the this context as the element which triggers the Ajax request is to add this line in jquery.unobtrusive-ajax.js file just before $.ajax(options) line,   options.context = element;              Then run your application again and click the About link again, you will find that the this context in the callback function remains same whether you use Unobtrusive Ajax or not.       Summary:          In this article I showed you a breaking change and a simple workaround in ASP.NET MVC 3. If you are migrating your application from ASP.NET MVC 2(or 1) to ASP.NET MVC 3 and leveraging Unobtrusive Ajax feature then you need to consider this breaking change. Hopefully you will enjoy this article too.     SyntaxHighlighter.all()
