  • Suggestions on Working with this Inherited Generic Method

    - by blu
    We have inherited a project that is a wrapper around a section of the core business model. There is one method that takes a generic, finds items matching that type from a member and then returns a list of that type. public List<T> GetFoos<T>() { List<IFoo> matches = Foos.FindAll( f => f.GetType() == typeof(T) ); List<T> resultList = new List<T>(); foreach (var match in matches) { resultList.Add((T)obj); } } Foos can hold the same object cast into various classes in inheritance hierarchy to aggregate totals differently for different UI presentations. There are 20+ different types of descendants that can be returned by GetFoos. The existing code basically has a big switch statement copied and pasted throughout the code. The code in each section calls GetFoos with its corresponding type. We are currently refactoring that into one consolidated area, but as we are doing that we are looking at other ways to work with this method. One thought was to use reflection to pass in the type, and that worked great until we realized the Invoke returned an object, and that it needed to be cast somehow to the List <T>. Another was to just use the switch statement until 4.0 and then use the dynamic language options. We welcome any alternate thoughts on how we can work with this method. I have left the code pretty brief, but if you'd like to know any additional details please just ask.

  • How to give "Share with" option while opening documents in iphone mail

    - by rishabh
    So I've been going through the "Document Interaction Programming Topics for iOS". I've been able to achieve the "Open with myapp" option through Mail, was wondering how can I change the option to "Share with myapp" depending upon the file types specified? This is what I've tried: <key>CFBundleDocumentTypes</key> <array> <dict> <key>CFBundleTypeName</key> <string>Document</string> <key>LSHandlerRank</key> <string>Alternate</string> <key>CFBundleTypeRole</key> <string>Owner</string> <key>LSItemContentTypes</key> <array> <string>public.data</string> </array> </dict> </array>

  • Error 1606. Could not access network location %SystemDrive%\inetpub\wwwroot\ while installing on IIS

    - by Mark
    I'm trying to port our software installer which currently supports Windows 2000 and Windows 2003 to a Windows 2008 environment. Currently, the installer gets an error which reads "Error 1606. Could not access network location %SystemDrive%\inetpub\wwwroot." %SystemDrive% is without a doubt C:\, and C:\inetpub\wwwroot\ has the correct accessibility. It is interesting that if I hardcode the path in the following keys in the registry to C:\inetpub\wwwroot\, without using the environment variable, the installer works correctly. • HKLM/Software/Wow6432Node/Microsoft/InetStp/PathWWWRoot • KHLM/Software/Microsoft/InetStp/PathWWWRoot. This seems like a very poor hack. I do not want to tell our clients that they need to hack their registry before they will be able to install our product. Another option is to change the registry behind the scenes, do our install, and revert the registry keys to their original values at the end of the install, but obviously I don't like this solution either. I find it hard to believe that Microsoft would have done this without reason, so there must be an alternate approach to get these installers to work without modifying the registry. Any tips appreciated.

  • Windows Server 2012 Branchcache vs. DFS-R

    - by TheCleaner
    Warning, subjective question ahead! But hopefully a good one that won't get closed. SCENARIO: I have a branch office that currently has no on-premise server. They access everything including a DC across a 12Mbps WAN link (MPLS). The link isn't saturated, averaging around 20% utilization. The circuit is very stable and has a high SLA and excellent uptime. However, large file transfers (mainly reads, not writes) from the file server across the WAN can be slow. We don't currently utilize DFS. RESEARCH DONE: I'm aware of WAN acceleration, using either dedicated hardware (Riverbed) or a dedicated software VM (Silver Peak) for example. But the pricing is outside of our current budget and the need isn't quite there yet from our perspective (since the issue is mainly in a "pull" scenario not necessarily push/pull). I'm mainly looking at deploying a Windows server at this branch office and either utilizing DFS-R or BranchCache. Looking at a table comparison and assuming we are looking at a "hosted branchcache server" and not simply distributed: It would appear there are benefits to both, even if both are "hosted" on a server. QUESTIONS I ACTUALLY HAVE: In what scenarios do each of these techs shine and where do you choose one over the other? Looking at a hosted Branchcache server, can you set "pre-fetching" of certain folders/files on the central file server so that they are immediately accessible locally at the branch? Do you have to do this on a schedule (if it is possible)? Looking at DFS-R my concern (and apparently solved with 3rd party apps) is file locking and making sure the file gets updated properly during a write operation (ie, making sure if both copies are accessed and both are written to, which file takes precedence and what happens to the changes?). Ideal it would seem would be to lock any alternate replicas of the data, but is it really that big of an issue? Does Branchcache lock the central file for editing? Does branchcache only transmit the deltas back to the central file of what has changed? Would either technology be ill advised if the branch office server was going to be utilized as a domain controller as well?

  • Ububtu server 12.04 auto installation freezes at kickseeding running if ks.cfg has post scripts

  • WSS and CAG , _layout pages break

    - by Mike
    Alright, I've searched everywhere and I cannot find the answer, due to the rarity of our setup. WSS 3.0/IIS 6.0/WinServer 2003 We have a sharepoint site that is in good shape, almost. Its TCP and SSL port are uncommon and need to be rerouted to work properly. This is where the Citrix Access Gateway (CAG) comes in play. It will redirect any request from URL (something.something.com) to the correct SSL port on the correct server. My AAM is configured to Default something.something.com and nothing else, since the CAG will provide the port. We use FBA, and require SSL. This works perfectly for everything that is safe or that is anything that an end user can see, but if I try to add a webpart, it errors out. Whereas if I add it internally, or bypass the CAG the webpart adds fine. The same goes for most of the _layouts pages, like _layouts/new.aspx. If I add a Link List/Doc library on the something.something.com, it errors out (Page cannot be displayed) and the page won't display, but if I try it with an internal address it will work fine. I found that if I am trying to add something or doing anything administrative, the site will navigate to the pages that I need to go to fine, but when i actually ADD something the URL will change from something.something.com to something.something.com:SSLport, thus erroring out the site. The URL with the SSL port shows on the Site URL when navigating to Site Settings. However, if I bypass the CAG, using the internal address the _layouts page works like a charm and i can add anything. All the CAG does is reroute a DNS request to the provided server and port. I've tried reextending the application, no luck same thing. I've tried changing the AAM to hide the port and the CAG rejects it. I've tried to recreate a new webapp/site collection with the same rules on the CAG, same thing occurs. Correct me if I'm wrong, and please provide me with some feedback and answers. Any suggestions would be very appreciated. Is it the CAG or the Alternate Access Mappings (AAM)?

  • Email delivery management grievances

    - by joxl
    The question I have may be more of principle than anything else, but here's my dilemma. I manage an email system for a small company (about 20 email users). We own a plain-letter .com domain name through Network Solutions. Our email service is hosted by Google Apps. Recently (Feb. 2011) we've been having customers report that they aren't getting our emails. Upon further investigation it seems that the failed emails are all to a common (well known) domain. We have not received any bounce messages for the emails. We've also contacted a few of the intended recipients, who have reported that the messages are not in their spam box; they simply did not receive anything. In these cases we re-sent the same email to an alternate address on another domain, which was successful received. One customer contacted their email provider about the issue. The provider recommended that we submit a form to be white-listed by their domain. Here's where my problem begins. I feel like this is heading down a slippery slope. Doesn't this undermine the very principle of email? If this is the appropriate action to take in these situations where will it end? In theory (following this model) it could be argued that eventually one will first need to "whitelist" (or more appropriately termed "authenticate") themselves with an email host before actually sending any messages. More to this point, what keeps the "bad" spammers from doing the same thing...? We've just gone full circle. I know avoiding anti-spam measures is a big cat-and-mouse game, but I think this is the wrong way of "patching" the problem. Email standards say that messages should not just disappear silently. I have a problem supporting a model that says "you must do < this to make sure your emails aren't ignored". I have a notion to call the provider and voice my complaint, although I have a feeling it will probably fall on deaf ears. Am I missing something here? Is this an acceptable approach to email spam problems? What should I do?

  • Checking the configuration of two systems to determine changes

    - by None
    We are standing up a replicant data center at work and need to ensure that the new data center is configured (nearly) identically to the original. The new data center will be differently addressed and named than the original and will have differing user accounts, but all the COTS, patches, and configurations should be the same. We would normally ghost the original servers and install those images onto the new machines, however, we have a few problematic pieces of COTS that require we install them outside of an image due to how they capture the setup of the network during their installation and maintain it within their configuration information (in some cases storing it in various databases). We have tried multiple times and this piece of COTS cannot be captured within a ghost image unless the destination machine will have an identical network setup (all the same IPs, hostnames, user accounts, etc across the entire network) as the original. In truth, it is the setup of these special COTS that I want to audit the most because they are difficult to install and configure in the first place. In light of the fact that we can’t simply ghost, I’m trying to find a reasonable manner to audit the new data center and check to see if it is setup like the original (some sort of system wide configuration audit or integrity check). I’m considering using something like Tripwire for Servers to capture the configuration on the source machines and then run an audit on the destination machines. I understand that it will still show some differences due to the minor config changes, but I’m hoping that it will eliminate the majority of the work. Here are some of the constraints I’m working under: Data center is comprised of multiple Windows and Linux machines of differing versions (about 20 total) I absolutely cannot ghost or snap any other type of image of these machines … at least not in their final configuration I want to audit the final configuration to ensure all of the COTS, patches, configurations, etc are installed and setup properly (as compared to the original data center) I would rather not install any additional tools on these machines … I’d much rather run it from a standalone machine or off a DVD Price of tools is important but not an impossible burden, however, getting a solution soon is important (I can’t take the time to roll my own tools to do this) For the COTS that stores the network information, I don’t know all of the places it stores the network information … so it would be unlikely I could find a way in the near future to adjust its setup after the installation has occurred Anyone have any thoughts or alternate approaches? Can anyone recommend tools that would be usable for system wide configuration audits?

  • Open a terminal window & run command, then close the terminal window if command completed successfully?

    - by Caspar
    I'm trying to write a script to do the following: Open a terminal window which runs a long running command (Ideally) move the terminal window to the top left corner of the screen using xdotool Close the terminal window only if the long running command exited with a zero return code To put it in Windows terms, I'd like to have the Linux equivalent of start cmd /c long_running_cmd if long_running_cmd succeeds, and do the equivalent of start cmd /k long_running_cmd if it fails. What I have so far is a script which starts xterm with a given command, and then moves the window as desired: #!/bin/bash # open a new terminal window in the background with the long running command xterm -e ~/bin/launcher.sh ./long_running_cmd & # move the terminal window (requires window process to be in background) sleep 1 xdotool search --name launcher.sh windowmove 0 0 And ~/bin/launcher.sh is intended to run whatever is passed as a command line argument to it: #!/bin/bash # execute command line arguments $@ But, I haven't been able to get the xterm window to close after long_running_cmd is done. I think something like xterm -e ~/bin/launcher.sh "./long_running_cmd && kill $PPID" & might be what I'm after, so that xterm is launched in the background and it runs ./long_running_cmd && kill $PPID. So the shell in the xterm window then runs the long running command and if it completes successfully, the parent process of the shell (i.e. the process owning the xterm window) is killed, thereby closing the xterm window. But, that doesn't work: nothing happens, so I suspect my quoting or escaping is incorrect, and I haven't been able to fix it. An alternate approach would be to get the PID of long_running_cmd, use wait to wait for it to finish, then kill the xterm window using kill $! (since $! refers to last task started in the background, which will be the xterm window). But I can't figure out a nice way to get the PID & exit value of long_running_cmd out of the shell running in the xterm window and into the shell which launched the xterm window (short of writing them to a file somewhere, which seems like it should be unnecessary?). What am I doing wrong, or is there an easier way to accomplish this?

  • "Error 1067: The process terminated unexpectedly" when trying to install MySQL on Win7 x64.

    - by Gravitas
    Hi, I've run into a brick wall trying to install MySQL v5.5 on my machine. My PC is Windows 7 x64, Enterprise edition. MySQL installs fine, but when I run the "MySQL Instance Configuration Wizard", it pauses forever on the step "Start Service" (I can let it run for 30 minutes with no response). If I go into services, I see that the "MySQL" service hasn't started, and if I try to start it, it says "Windows could not start MySQL Service on Local Computer. Error 1067: The process terminated unexpectedly." I've tried the following: Turning off firewall. Uninstalling all antivirus software. Installing / reinstalling 32-bit version of MySQL. Installing / reinstalling 64-bit version of MySQL. Uninstalling, deleting the contents of "C:\program files\MySQL" and "C:\program files (x86)\MySQL", reinstalling. Checking to see that there is no rogue services named MySQL???? (from a previous install). Checking that port 3306 is not used by an alternate program. Changing the default port that MySQL uses. Checking for "my.ini" and "my.ini.cnf" in "C:\windows" (nothing there but that can cause a problem). Running both MySQL installer, and configuration wizard, in "Adminstrator mode". Turning off UAC. Installing with defaults, not changing anything. Rebooting my machine (about 6 reboots so far). Opening up port 3306 in the firewall (both TCP and UDP, inbound and outbound). Swearing at the klutz of a programmer who designed MySQL so you can't even install it (as if that would help!) My machine is working 100% in every other way. InfiniDB (a MySQL compatible database) installs 100%, as does Visual Studio 2010, Microsoft SQL Server, etc, etc. Your advice on how to work around this? p.s. Here is the screen it got stuck on for 15 minutes until I killed the process: Update 2010-12-20 Tried MySQL v5.1, it didn't work either. Its amazing - if you type "mysqld /?", or "mysqld -help", it doesn't give you any help. And, if you try to restart the service manually, it doesn't display any error messages. Could it be any more unhelpful? Update 2010-12-21 Installed MySQL 6.0 alpha, and it worked. However, I'd rather not use an alpha release, given that the "stable" release is anything but :( Update 2010-12-21 Found http://dev.mysql.com/doc/refman/5.1/en/windows-troubleshooting.html, dealing with troubleshooting under Windows. Discovered that you can generate an error log if the service doesn't start - see here: http://dev.mysql.com/doc/refman/5.1/en/error-log.html

  • How can I change how OS X's 'say' command pronounces a word?

    - by jwhitlock
    OS X's say command is useful for some tasks (such as Skype's 'notify me when a contact comes online), but it is pronouncing some names incorrectly. Is there a way to teach say to pronounce a word differently? For example, try: say "Hi, Joel Spolsky" The 'ol' sounds like 'ball' rather than 'old'. I'd like to add an exception that say "Pronounce Spolsky like this", rather than try to teach new linguistic rules. I bet there is a way since it can pronounce "iphone" as Apple wants. Update - After some research, here's what I've learned: Text-to-speech is split between turning the text to phonemes, and then the phonemes are turned into audio using a voice. Changing the voice doesn't effect the phonemes. The Speech Synthesis Manager has some functions for turning text to phonemes, and a method for registering a speech dictionary that will add new text-phoneme maps. However, Apple's speech dictionary must be in a binary form - I didn't find any plist XML. Using dtrace while running say, I found some interesting files opened in /System/Library/PrivateFrameworks/SpeechDictionary.framework/Resources. This is probably the speech dictionary, but they are all binary, except for Homophones, which is XML. Adding entries to Homophones does nothing - it is probably used in speech-to-text. They are also code signed by Apple - changing them may prevent some programs from working. PrefixDictionary CartNames CartLite SymbolDictionary Homophones There are ways to add text versions of application interface elements so VoiceOver works, a lot of which a developer gets for free, but there are tricky bits. The standard here appears to be to use a phonetic spelling as needed. My guesses are: say is a light layer of code on top of the Speech Synthesis Manager. It would be easy for the Apple devs to add a command line option to take the path to a speech dictionary plist for alternate phoneme mapping, but they didn't. It may be a useful open-source project to write a better say. Skype probably uses Speech Synthesis Manager directly, leaving no hooks to change the way my friend's names are pronounced, other than spelling them phonetically, which is silly. The easiest way to make a command line version of say is how JRobert suggested. Here's my quick implementation, using Doug Harris's spelling suggestion: #!/bin/sh echo $@ | tr '[A-Z]' '[a-z]' | sed "s/spolsky/spowlsky/g" | /usr/bin/say Finally, some fun command line stuff: # Apple is weird sqlite3 /System/Library/PrivateFrameworks/SpeechDictionary.framework/Resources/Tuples .dump # Get too much information about what files are being opened sudo dtrace -n 'syscall::open*:entry { printf("%s %s",execname,copyinstr(arg0)); }' # Just fun say -v bad "Joel Spolsky Spolsky Spolsky Spolsky Spolsky, Joel Spolsky Spolsky Spolsky Spolsky Spolsky" echo "scale=1000; 4*a(1)" | bc -l | say

  • Computer freezes +/- 30 seconds, suspicion on SSD

    - by Robert vE
    My computer freezes for about 30 seconds, this happens occasionally. When it happens I can still move the mouse, sometimes even alternate between tabs in google chrome. If I try to open windows explorer nothing happens. Also chrome rapports "waiting for cache". It also happens in starcraft II, during which the sounds loops. I have made a Trace as this topic describes: How do I troubleshoot a Windows 7 freeze or slowness? Trace: https://docs.google.com/open?id=0B_VkKdh535p6NklhSDdBLURUMnc I have looked at it, but I couldn't figure it out. My system specs are: AMD Athlon X4 651 Asus Ati HD6670 ADATA SSD sp900 Asus f1a55 mainboard 4 GB crucial 1333 ram 500 watt atx ps I'm running Windows 7, fully updated. Any help is much appreciated. Update: I tried something before your reply that may have helped the problem. I don't know for sure if it has, it's too soon to tell. A bit of history first. I had problems installing win7 on my ssd from the start. In IDE mode it worked, but I had the same problems as above. AHCI was a total fail, with it on before install as well as turning it on after install (including tweaking register). I didn't bother installing the AMD chipset/AHCI as it was reported to have no TRIM function and thus make problems worse. Eventually I did install the AMD SMbus driver as the stability issues were driving me crazy. It worked, no more issues, until I installed some extra drivers and software. Audio/LAN/ASUS suite, I don’t see the relation, but somehow it screwed up my system again. As a last effort I posted here on this site. After which the thought occurred to me turn on AHCI again as by now I had all necessary drivers installed anyway. (plus all windows updates downloaded/installed in the meantime) I did and stability didn’t seem great the first few reboots, but eventually everything seemed to work great. I tried to play starcraft II – an almost guaranteed freeze before – and I had no problems. I’m basically crossing my fingers and hope the problem is gone for good. I still think it has something to do with my SSD. In my research into the problem I noticed a lot of these issues with sandforce 2281 firmware, the exact same firmware I have. People reported the same problem that I had, freezes. Additionally they reported that during a freeze the hdd light stayed on, I noticed after I read this that this happened with my computer as well. None of this is conclusive evidence that my SSD is really to fault, but it is suspicious. And why turning on AHCI would fix it I don’t know. Thank you Tom for taking a look, if the problem returns I will certainly do what you advised.

  • Script to check a shared Exchange calendar and then email detail

    - by SJN
    We're running Server and Exchange 2003 here. There's a shared calendar which HR keep up-to-date detailing staff who are on leave. I'm looking for a VB Script (or alternate) which will extract the "appointment" titles of each item for the current day and then email the detail to a mail group, in doing so notifying the group with regard to which staff are on leave for the day.

  • Melting Laptop Power Supply Tip

    - by AlReece45
    Several (6-7) months ago, my laptop power supply cord got a cut in it and stopped working. Having gotten cheap (and short) power supplies in the past, I decided to buy 2 brand new ones from the manufacturer (ASUS). Now, I used my laptop a little less than usual between February and March. During that time I noticed a few times that the power supply, even though plugged in, did not provide power. Often the computer would just off on me. I figured it was just that one power supply being bad. I had left the alternate at my parent's house in another state and asked them to ship it to me. Now, at work the other day I wanted to get a file off the of hard disk. So I booted it up, knowing that it had a low battery, plugged it in. During the first 2 minutes of use, I was told that the battery was low and I should plug it in. I unplugged it, inspected the end (Being plugged in, this was suspicious), and decided I shouldn't plug it back in-- the plastic on the tip was melting from the heat of the metal on the tip. The computer had simply booted up and I had the file-manager open. It had not been on for more than 10 hours. Now I know that computers tend to get pretty hot. However, the melting point of plastic is usually above 200C.. so that's much hotter than the computer should be generating. I went and bought a THIRD power supply. This time a universal one from Best Buy (it was very fast to buy and test). I tried it out on the computer and it's tip is melting as well. My older laptop that uses the universal power supply uses it perfectly (has been about a week and a part of use now). I have tried using the computer without the battery, with the same effect. Obviously, this is not a problem with the power supply. My room mate and I being trained computer techs were contemplating taking the computer apart and desoldering and resoldering on the power tip. (The computer is about 6 months out of its 2-year warranty). We're hoping that will correct the issue as I would prefer to devote my money on a Good Desktop rather than yet ANOTHER $1200+ laptop. Is there any thing I'm missing here that might cause the the tip on the power unit to melt?

  • SharePoint 2010 – Central Admin tooling to create host header site collections

    - by eJugnoo
    Just like SharePoint 2007, you can create host-header based site collections in SharePoint 2010 as well. It means, that you do not necessarily need to create a site-collection under a managed path like /sites/, you can create multiple root-level site collections on same web-application/port by using host-header site collections. All you need to do is point your domain or sub-domain to your web-application and create a matching site-collection that you want. But, just like in 2007, it is something that you do by using STSADM, and is not available on Central Admin UI in 2010 as well. Yeah, though you can now also use PowerShell to create one: C:\PS>$w = Get-SPWebApplication http://sitename   C:\PS>New-SPSite http://www.contoso.com -OwnerAlias "DOMAIN\jdoe" -HostHeaderWebApplication $w -Title "Contoso" -Template "STS#0"   This example creates a host header site collection. Because the template is provided, the root Web of this site collection will be created. .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } I’ve been playing with WCM in SharePoint 2010 more and more, and for that I preferred creating hosts file entries for desired domains and create site-collections by those headers – in my dev environment. I used PowerShell initially, but then got interested to build my own UI on Central Admin instead. Developed with Visual Studio 2010 So I used new Visual Studio 2010 tooling to create an empty SharePoint 2010 project. Added an application page (there is no option to add _Admin page item in VS 2010 RC), that got created in Layouts “mapped” folder. Created a new Admin mapped folder for 14-“hive”, and moved my new page there instead. Yes, I didn’t change the base class for page, its just that it runs under _admin, but it is indeed a LayoutsPageBase inherited page. To introduce a action-link in Central Admin console, I created following element: 1: <Elements xmlns="http://schemas.microsoft.com/sharepoint/"> 2: <CustomAction 3: Id="CreateSiteByHeader" 4: Location="Microsoft.SharePoint.Administration.Applications" 5: Title="Create site collections by host header" 6: GroupId="SiteCollections" 7: Sequence="15" 8: RequiredAdmin="Delegated" 9: Description="Create a new top-level web site, by host header" > 10: <UrlAction Url="/_admin/OfficeToolbox/CreateSiteByHeader.aspx" /> 11: </CustomAction> 12: </Elements> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Used Reflector to understand any special code behind createpage.aspx, and created a new for our purpose – CreateSiteByHeader.aspx. From there I quickly created a similar code behind, without all the fancy of Farm Config Wizard handling and dealt with alternate implementations of sealed classes! Goal was to create a professional looking and OOB-type experience. I also added Regex validation to ensure user types a valid domain name as header value. Below is the result…   Release @ Codeplex I’ve released to WSP on OfficeToolbox @ Codeplex, and you can download from here. Hope you find it useful… -- Sharad

  • Integrate Nitro PDF Reader with Windows 7

    - by Matthew Guay
    Would you like a lightweight PDF reader that integrates nicely with Office and Windows 7?  Here we look at the new Nitro PDF Reader, a nice PDF viewer that also lets you create and markup PDF files. Adobe Reader is the de-facto PDF viewer, but it only lets you view PDFs and not much else.  Additionally, it doesn’t fully integrate with 64-bit editions of Vista and Windows 7.  There are many alternate PDF readers, but Nitro PDF Reader is a new entry into this field that offers more features than most PDF readers.  From the creators of the popular free PrimoPDF printer, the new Reader lets you create PDFs from a variety of file formats and markup existing PDFs with notes, highlights, stamps, and more in addition to viewing PDFs.  It also integrates great with Windows 7 using the Office 2010 ribbon interface. Getting Started Download the free Nitro PDF Reader (link below) and install as normal.  Nitro PDF Reader has separate versions for 32 & 64-bit editions of Windows, so download the correct one for your computer. Note:  Nitro PDF Reader is still in Beta testing, so only install if you’re comfortable with using beta software. On first run, Nitro PDF Reader will ask if you want to make it the default PDF viewer.  If you don’t want to, make sure to uncheck the box beside Always perform this check to keep it from opening this prompt every time you use it. It will also open an introductory PDF the first time you run it so you can quickly get acquainted with its features. Windows 7 Integration One of the first things you’ll notice is that Nitro PDF Reader integrates great with Windows 7.  The ribbon interface fits right in with native applications such as WordPad and Paint, as well as Office 2010. If you set Nitro PDF Reader as your default PDF viewer, you’ll see thumbnails of your PDFs in Windows Explorer. If you turn on the Preview Pane, you can read full PDFs in Windows Explorer.  Adobe Reader lets you do this in 32 bit versions, but Nitro PDF works in 64 bit versions too. The PDF preview even works in Outlook.  If you receive an email with a PDF attachment, you can select the PDF and view it directly in the Reading Pane.  Click the Preview file button, and you can uncheck the box at the bottom so PDFs will automatically open for preview if you want.   Now you can read your PDF attachments in Outlook without opening them separately.  This works in both Outlook 2007 and 2010. Edit your PDFs Adobe Reader only lets you view PDF files, and you can’t save data you enter in PDF forms.  Nitro PDF Reader, however, gives you several handy markup tools you can use to edit your PDFs.  When you’re done, you can save the final PDF, including information entered into forms. With the ribbon interface, it’s easy to find the tools you want to edit your PDFs. Here we’ve highlighted text in a PDF and added a note to it.  We can now save these changes, and they’ll look the same in any PDF reader, including Adobe Reader. You can also enter new text in PDFs.  This will open a new tab in the ribbon, where you can select basic font settings.  Select the Click To Finish button in the ribbon when you’re finished editing text.   Or, if you want to use the text or pictures from a PDF in another application, you can choose to extract them directly in Nitro PDF Reader.  Create PDFs One of the best features of Nitro PDF Reader is the ability to create PDFs from almost any file.  Nitro adds a new virtual printer to your computer that creates PDF files from anything you can print.  Print your file as normal, but select the Nitro PDF Creator (Reader) printer. Enter a name for your PDF, select if you want to edit the PDF properties, and click Create. If you choose to edit the PDF properties, you can add your name and information to the file, select the initial view, encrypt it, and restrict permissions. Alternately, you can create a PDF from almost any file by simply drag-and-dropping it into Nitro PDF Reader.  It will automatically convert the file to PDF and open it in a new tab in Nitro PDF. Now from the File menu you can send the PDF as an email attachment so anyone can view it. Make sure to save the PDF before closing Nitro, as it does not automatically save the PDF file.   Conclusion Nitro PDF Reader is a nice alternative to Adobe Reader, and offers some features that are only available in the more expensive Adobe Acrobat.  With great Windows 7 integration, including full support for 64-bit editions, Nitro fits in with the Windows and Office experience very nicely.  If you have tried out Nitro PDF Reader leave a comment and let us know what you think.

  • How to Assign a Static IP Address in XP, Vista, or Windows 7

    - by Mysticgeek
    When organizing your home network it’s easier to assign each computer it’s own IP address than using DHCP. Here we will take a look at doing it in XP, Vista, and Windows 7. If you have a home network with several computes and devices, it’s a good idea to assign each of them a specific address. If you use DHCP (Dynamic Host Configuration Protocol), each computer will request and be assigned an address every time it’s booted up. When you have to do troubleshooting on your network, it’s annoying going to each machine to figure out what IP they have. Using Static IPs prevents address conflicts between devices and allows you to manage them more easily. Assigning IPs to Windows is essentially the same process, but getting to where you need to be varies between each version. Windows 7 To change the computer’s IP address in Windows 7, type network and sharing into the Search box in the Start Menu and select Network and Sharing Center when it comes up.   Then when the Network and Sharing Center opens, click on Change adapter settings. Right-click on your local adapter and select Properties. In the Local Area Connection Properties window highlight Internet Protocol Version 4 (TCP/IPv4) then click the Properties button. Now select the radio button Use the following IP address and enter in the correct IP, Subnet mask, and Default gateway that corresponds with your network setup. Then enter your Preferred and Alternate DNS server addresses. Here we’re on a home network and using a simple Class C network configuration and Google DNS. Check Validate settings upon exit so Windows can find any problems with the addresses you entered. When you’re finished click OK. Now close out of the Local Area Connections Properties window. Windows 7 will run network diagnostics and verify the connection is good. Here we had no problems with it, but if you did, you could run the network troubleshooting wizard. Now you can open the command prompt and do an ipconfig  to see the network adapter settings have been successfully changed.   Windows Vista Changing your IP from DHCP to a Static address in Vista is similar to Windows 7, but getting to the correct location is a bit different. Open the Start Menu, right-click on Network, and select Properties. The Network and Sharing Center opens…click on Manage network connections. Right-click on the network adapter you want to assign an IP address and click Properties. Highlight Internet Protocol Version 4 (TCP/IPv4) then click the Properties button. Now change the IP, Subnet mask, Default Gateway, and DNS Server Addresses. When you’re finished click OK. You’ll need to close out of Local Area Connection Properties for the settings to go into effect. Open the Command Prompt and do an ipconfig to verify the changes were successful.   Windows XP In this example we’re using XP SP3 Media Center Edition and changing the IP address of the Wireless adapter. To set a Static IP in XP right-click on My Network Places and select Properties. Right-click on the adapter you want to set the IP for and select Properties. Highlight Internet Protocol (TCP/IP) and click the Properties button. Now change the IP, Subnet mask, Default Gateway, and DNS Server Addresses. When you’re finished click OK. You will need to close out of the Network Connection Properties screen before the changes go into effect.   Again you can verify the settings by doing an ipconfig in the command prompt. In case you’re not sure how to do this, click on Start then Run.   In the Run box type in cmd and click OK. Then at the prompt type in ipconfig and hit Enter. This will show the IP address for the network adapter you changed.   If you have a small office or home network, assigning each computer a specific IP address makes it a lot easier to manage and troubleshoot network connection problems.

  • Share a Printer on Your Network from Vista or XP to Windows 7

    - by Mysticgeek
    The other day we looked at sharing a printer between Windows 7 machines, but you may only have one Windows 7 machine and the printer is connected to a Vista or XP computer. Today we show you how to share a printer from either Vista or XP to Windows 7. We previously showed you how to share files and printers between Windows 7 and XP. But what if you have a printer connected to an XP or Vista machine in another room, and you want to print to it from Windows 7? This guide will walk you through the process. Note: In these examples we’re using 32-bit versions of Windows 7, Vista, and XP on a basic home network. We are using an HP PSC 1500 printer, but keep in mind every printer is different so finding and installing the correct drivers will vary. Share a Printer from Vista To share the printer on a Vista machine click on Start and enter printers into the search box and hit Enter. Right-click on the printer you want to share and select Sharing from the context menu. Now in Printer Properties, select the Sharing tab, mark the box next to Share this printer, and give the printer a name. Make sure the name is something simple with no spaces then click Ok. Share a Printer from XP To share a printer from XP click on Start then select Printers and Faxes. In the Printers and Faxes window right-click on the printer to share and select Sharing. In the Printer Properties window select the Sharing tab and the radio button next to Share this printer and give it a short name with no spaces then click Ok. Add Printer to Windows 7 Now that we have the printer on Vista or XP set up to be shared, it’s time to add it to Windows 7. Open the Start Menu and click on Devices and Printers. In Devices and Printers click on Add a printer. Next click on Add a network, wireless or Bluetooth printer. Windows 7 will search for the printer on your network and once its been found click Next. The printer has been successfully added…click Next. Now you can set it as the default printer and send a test page to verify everything works. If everything is successful, close out of the add printer screens and you should be good to go.   Alternate Method If the method above doesn’t work, you’ll can try the following for either XP or Vista. In our example, when trying to add the printer connected to our XP machine, it wasn’t recognized automatically. If you’re search pulls up nothing then click on The printer that I want isn’t listed. In the Add Printer window under Find a printer by name or TCP/IP address click the radio button next to Select a shared printer by name. You can either type in the path to the printer or click on Browse to find it. In this instance we decided to browse to it and notice we have 5 computers found on the network. We want to be able to print to the XPMCE computer so we double-click on that. Type in the username and password for that computer… Now we see the printer and can select it. The path to the printer is put into the Select a shared printer by name field. Wait while Windows connects to the printer and installs it… It’s successfully added…click Next. Now you can set it as the default printer or not and print a test page to make sure everything works successfully. Now when we go back to Devices and Printers under Printers and Faxes, we see the HP printer on XPMCE. Conclusion Sharing a printer from one machine to another can sometimes be tricky, but the method we used here in our setup worked well. Since the printer we used is fairly new, there wasn’t a problem with locating any drivers for it. Windows 7 includes a lot of device drivers already so you may be surprised on what it’s able to install. Your results may vary depending on your type of printer, Windows version, and network setup. This should get you started configuring the machines on your network—hopefully with good results.  If you you have two Windows 7 computers, then sharing a printer or files is easy through the Homegroup feature. You can also share a printer between Windows 7 machines on the same network but not Homegroup.

  • Troubleshooting Application Timeouts in SQL Server

    - by Tara Kizer
    I recently received the following email from a blog reader: "We are having an OLTP database instance, using SQL Server 2005 with little to moderate traffic (10-20 requests/min). There are also bulk imports that occur at regular intervals in this DB and the import duration ranges between 10secs to 1 min, depending on the data size. Intermittently (2-3 times in a week), we face an issue, where queries get timed out (default of 30 secs set in application). On analyzing, we found two stored procedures, having queries with multiple table joins inside them of taking a long time (5-10 mins) in getting executed, when ideally the execution duration ranges between 5-10 secs. Execution plan of the same displayed Clustered Index Scan happening instead of Clustered Index Seek. All required Indexes are found to be present and Index fragmentation is also minimal as we Rebuild Indexes regularly alongwith Updating Statistics. With no other alternate options occuring to us, we restarted SQL server and thereafter the performance was back on track. But sometimes it was still giving timeout errors for some hits and so we also restarted IIS and that stopped the problem as of now." Rather than respond directly to the blog reader, I thought it would be more interesting to share my thoughts on this issue in a blog. There are a few things that I can think of that could cause abnormal timeouts: Blocking Bad plan in cache Outdated statistics Hardware bottleneck To determine if blocking is the issue, we can easily run sp_who/sp_who2 or a query directly on sysprocesses (select * from master..sysprocesses where blocking <> 0).  If blocking is present and consistent, then you'll need to determine whether or not to kill the parent blocking process.  Killing a process will cause the transaction to rollback, so you need to proceed with caution.  Killing the parent blocking process is only a temporary solution, so you'll need to do more thorough analysis to figure out why the blocking was present.  You should look into missing indexes and perhaps consider changing the database's isolation level to READ_COMMITTED_SNAPSHOT. The blog reader mentions that the execution plan shows a clustered index scan when a clustered index seek is normal for the stored procedure.  A clustered index scan might have been chosen either because that is what is in cache already or because of out of date statistics.  The blog reader mentions that bulk imports occur at regular intervals, so outdated statistics is definitely something that could cause this issue.  The blog reader may need to update statistics after imports are done if the imports are changing a lot of data (greater than 10%).  If the statistics are good, then the query optimizer might have chosen to scan rather than seek in a previous execution because the scan was determined to be less costly due to the value of an input parameter.  If this parameter value is rare, then its execution plan in cache is what we call a bad plan.  You want the best plan in cache for the most frequent parameter values.  If a bad plan is a recurring problem on your system, then you should consider rewriting the stored procedure.  You might want to break up the code into multiple stored procedures so that each can have a different execution plan in cache. To remove a bad plan from cache, you can recompile the stored procedure.  An alternative method is to run DBCC FREEPROCACHE which drops the procedure cache.  It is better to recompile stored procedures rather than dropping the procedure cache as dropping the procedure cache affects all plans in cache rather than just the ones that were bad, so there will be a temporary performance penalty until the plans are loaded into cache again. To determine if there is a hardware bottleneck occurring such as slow I/O or high CPU utilization, you will need to run Performance Monitor on the database server.  Hopefully you already have a baseline of the server so you know what is normal and what is not.  Be on the lookout for I/O requests taking longer than 12 milliseconds and CPU utilization over 90%.  The servers that I support typically are under 30% CPU utilization, but your baseline could be higher and be within a normal range. If restarting the SQL Server service fixes the problem, then the problem was most likely due to blocking or a bad plan in the procedure cache.  Rather than restarting the SQL Server service, which causes downtime, the blog reader should instead analyze the above mentioned things.  Proceed with caution when restarting the SQL Server service as all transactions that have not completed will be rolled back at startup.  This crash recovery process could take longer than normal if there was a long-running transaction running when the service was stopped.  Until the crash recovery process is completed on the database, it is unavailable to your applications. If restarting IIS fixes the problem, then the problem might not have been inside SQL Server.  Prior to taking this step, you should do analysis of the above mentioned things. If you can think of other reasons why the blog reader is facing this issue a few times a week, I'd love to hear your thoughts via a blog comment.

  • A Rose by Any Other Name..

    - by Geoff N. Hiten
    It is always a good start when you can steal a title line from one of the best writers in the English language.  Let’s hope I can make the rest of this post live up to the opening.  One recurring problem with SQL server is moving databases to new servers.  Client applications use a variety of ways to resolve SQL Server names, some of which are not changed easily <cough SharePoint /cough>.  If you happen to be using default instances on both the source and target SQL Server, then the solution is pretty simple.  You create (or bug the network admin until she creates) two DNS “A” records. One points the old name to the new IP address.  The other creates a new alias for the old server, since the original system name is now redirected.  Note this will redirect ALL traffic from the old server to the new server, including RDP and file share connection attempts.    Figure 1 – Microsoft DNS MMC Snap-In   Figure 2 – DNS New Host Dialog Box Both records are necessary so you can still access the old server via an alternate name. Server Role IP Address Name Alias Source 10.97.230.60 SQL01 SQL01_Old Target 10.97.230.80 SQL02 SQL01 Table 1 – Alias List If you or somebody set up connections via IP address, you deserve to have to go to each app and fix it by hand.  That is the only way to fix that particular foul-up. If have to deal with Named Instances either as a source or a target, then it gets more complicated.  The standard fix is to use the SQL Server Configuration Manager (or one of its earlier incarnations) to create a SQL client alias to redirect the connection.  This can be a pain installing and configuring the app on multiple client servers.  The good news is that SQL Server Configuration Manager AND all of its earlier versions simply write a few registry keys.  Extracting the keys into a .reg file makes centralized automated deployment a snap. If the client is a 32-bit system, you have to extract the native key.  If it is a 64-bit, you have to extract the native key and the WoW (32 bit on 64 bit host) key. First, pick a development system to create the actual registry key.  If you do this repeatedly, you can simply edit an existing registry file.  Create the entry using the SQL Configuration Manager.  You must use a 64-bit system to create the WoW key.  The following example redirects from a named instance “SQL01\SQLUtiluty” to a default instance on “SQL02”.   Figure 3 – SQL Server Configuration Manager - Native Figure 3 shows the native key listing. Figure 4 – SQL Server Configuration Manager – WoW If you think you don’t need the WoW key because your app is 64 it, think again.  SQL Server Management Server is a 32-bit app, as are most SQL test utilities.  Always create both keys for 64-bit target systems. Now that the keys exist, we can extract them into a .reg file. Fire up REGEDIT and browse to the following location:  HKLM\Software\Microsoft\MSSQLServer\Client\ConnectTo.  You can also search the registry for the string value of one of the server names (old or new). Right click on the “ConnectTo” label and choose “Export”.  Save with an appropriate name and location.  The resulting file should look something like this: Figure 5 – SQL01_Alias.reg Repeat the process with the location: HKLM\Software\Wow6432Node\Microsoft\MSSQLServer\Client\ConnectTo Note that if you have multiple alias entries, ALL of the entries will be exported.  In that case, you can edit the file and remove the extra aliases. You can edit the files together into a single file.  Just leave a blank line between new keys like this: Figure 6 – SQL01_Alias_All.reg Of course if you have an automatic way to deploy, it makes sense to have an automatic way to Un-deploy.  To delete a registry key, simply edit the .reg file and replace the target with a “-“ sign like so. Figure 7 – SQL01_Alias_UNDO.reg Now we have the ability to move any database to any server without having to install or change any applications on any client server.  The whole process should be transparent to the applications, which makes planning and coordinating database moves a far simpler task.

  • A C# implementation of the CallStream pattern

    Dusan published this interesting post a couple of weeks ago about a novel JavaScript chaining pattern: http://dbj.org/dbj/?p=514 It’s similar to many existing patterns, but the syntax is extraordinarily terse and it provides a new form of friction-free, plugin-less extensibility mechanism. Here’s a JavaScript example from Dusan’s post: CallStream("#container") (find, "div") (attr, "A", 1) (css, "color", "#fff") (logger); The interesting thing here is that the functions that are being passed as the first argument are arbitrary, they don’t need to be declared as plug-ins. Compare that with a rough jQuery equivalent that could look something like this: $.fn.logger = function () { /* ... */ } $("selector") .find("div") .attr("A", 1) .css("color", "#fff") .logger(); There is also the “each” method in jQuery that achieves something similar, but its syntax is a little more verbose. Of course, that this pattern can be expressed so easily in JavaScript owes everything to the extraordinary way functions are treated in that language, something Douglas Crockford called “the very best part of JavaScript”. One of the first things I thought while reading Dusan’s post was how I could adapt that to C#. After all, with Lambdas and delegates, C# also has its first-class functions. And sure enough, it works really really well. After about ten minutes, I was able to write this: CallStreamFactory.CallStream (p => Console.WriteLine("Yay!")) (Dump, DateTime.Now) (DumpFooAndBar, new { Foo = 42, Bar = "the answer" }) (p => Console.ReadKey()); Where the Dump function is: public static void Dump(object options) { Console.WriteLine(options.ToString()); } And DumpFooAndBar is: public static void DumpFooAndBar(dynamic options) { Console.WriteLine("Foo is {0} and bar is {1}.", options.Foo, options.Bar); } So how does this work? Well, it really is very simple. And not. Let’s say it’s not a lot of code, but if you’re like me you might need an Advil after that. First, I defined the signature of the CallStream method as follows: public delegate CallStream CallStream (Action<object> action, object options = null); The delegate define a call stream as something that takes an action (a function of the options) and an optional options object and that returns a delegate of its own type. Tricky, but that actually works, a delegate can return its own type. Then I wrote an implementation of that delegate that calls the action and returns itself: public static CallStream CallStream (Action<object> action, object options = null) { action(options); return CallStream; } Pretty nice, eh? Well, yes and no. What we are doing here is to execute a sequence of actions using an interesting novel syntax. But for this to be actually useful, you’d need to build a more specialized call stream factory that comes with some sort of context (like Dusan did in JavaScript). For example, you could write the following alternate delegate signature that takes a string and returns itself: public delegate StringCallStream StringCallStream(string message); And then write the following call stream (notice the currying): public static StringCallStream CreateDumpCallStream(string dumpPath) { StringCallStream str = null; var dump = File.AppendText(dumpPath); dump.AutoFlush = true; str = s => { dump.WriteLine(s); return str; }; return str; } (I know, I’m not closing that stream; sure; bad, bad Bertrand) Finally, here’s how you use it: CallStreamFactory.CreateDumpCallStream(@".\dump.txt") ("Wow, this really works.") (DateTime.Now.ToLongTimeString()) ("And that is all."); Next step would be to combine this contextual implementation with the one that takes an action parameter and do some really fun stuff. I’m only scratching the surface here. This pattern could reveal itself to be nothing more than a gratuitous mind-bender or there could be applications that we hardly suspect at this point. In any case, it’s a fun new construct. Or is this nothing new? You tell me… Comments are open :)

  • Dual Boot Oracle Solaris 11/11 and Linux (Ubuntu 11.10/grub2)

    - by HartmutStreppel
    After having worked with Open Solaris on my laptop first, then with an upgrade to Oracle Solaris 11 Express, I finally did a fresh install of Oracle Solaris 11/11, when it became available. I am not a big fan of upgrades as I know that I am not the perfect administrator and my system gets spoiled with unclean configurations, outdated packages and wrong settings that cannot be reversed. So I prefer to start from scratch. Especially with Oracle Solaris 11 I wanted to have a system just like a customer would have it in production. The installation was smooth - more or less, if I had only read the documentation a bit better in advance. For a number of reasons I prefer a dual boot system. The most important one is, that especially with mobile devices you often run into network problems. And you have a hard time figuring out where the problem is: in your laptop hardware, in the OS you are running, or really within the network. If you have an alternate OS to boot, you can exclude the OS and your hardware. This makes you feel better. The second OS should be a Linux variant - and for some not so obvious reason I decided to go with the latest Ubuntu release (11.10). It replaced a very old Open Suse installation that had not been booted for a while. I knew that it was probably best to install Ubuntu first and then Oracle Solaris 11, as this would put the right boot information for Oracle Solaris  into the MBR and onto the root partition. But then, how to enable dual boot with the 2 OSes. Searching the web one mainly finds information about dual boot of: Linux and Linux Linux and Windows I do not want to explain which wrong configurations I worked through, but I prefer to explain the final setup, which is extremely simple, and I am wondering why this is not covered as the easiest solution for most dual boot setups. I use chainloader from and to both OS'es, with the only disadvantage that I have to confirm two grub menus each time I want to boot the "other" OS. Still there were some hurdles to jump over: Ubuntu did not like getting its boot blocks being placed on the partition instead of the disk; I must admit that I do not fully understand why. But using the --force option you could get that done Ubuntu needs an active partition; that was easy to achieve grub2 uses a different numbering scheme for the partitions. That is in the docs, if you read them. BTW: The usual disclaimer is valid. There is  no guarantee that what I describe works or works well. Please back up your data carefully before trying any of this. So, Oracle Solaris 11 is installed on the first partition and Ubuntu on the third. With Ubtuntu things initially were a bit more complicated, as I did not know how to boot it. And the live CD did not offer the capability to boot the on-disk image (at least I did not find it). So I booted the live CD, mounted the Ubuntu installation at /mnt and wrote the boot blocks into the partition. This is something that does not seem to be recommended, at least grub-install refrained from doing what I intended. After a bit more research I was bold enough to use the --force option and wrote the boot blocks to /dev/sda3 using grub-install --boot-directory=/mnt/boot --force --no-floppy /dev/sda3 So, I now had a system with the Solaris boot loader in the MBR, Solaris specific boot blocks on the Solaris root partition and Ubuntu specific boot blocks in the Ubuntu partition. I just had to chain them together and I was done. Oracle Solaris 11: I have added the following lines to /rpool/boot/grub/menu.lst (be aware of the /rpool!!!!) title Ubuntu 11.10root (hd0,2)makeactivechainloader +1boot The Ubuntu root file system sits on the third partition (/dev/sda3). Ubuntu: I have added the following lines to /etc/grub.d/40_custom: menuentry "Solaris 11/11" {      set root=(hd0,1)      chainloader +1} Two things need to be mentioned: a) grub2 starts numbering partitions with 1; so my /dev/sda1 is partition 1. b) Oracle Solaris boots without the partition being made active (btw: the command to make a partition active with grub2 is "parttool (hd0,1) boot+", which currently does not work for me). As debugging grub is a bit complicated, I used the grub CLI to perform some tests and also used a tool, that I found on sourceforge.net that was able to prepare a list of all boot loaders on all partitions. This told me that the basic setup was correct. Unfortunately I lost it in the live CD environment. I hope this is helpful for some of the readers.Hartmut

  • SQL SERVER – SmallDateTime and Precision – A Continuous Confusion

    - by pinaldave
    Some kinds of confusion never go away. Here is one of the ancient confusing things in SQL. The precision of the SmallDateTime is one concept that confuses a lot of people, proven by the many messages I receive everyday relating to this subject. Let me start with the question: What is the precision of the SMALLDATETIME datatypes? What is your answer? Write it down on your notepad. Now if you do not want to continue reading the blog post, head to my previous blog post over here: SQL SERVER – Precision of SMALLDATETIME. A Social Media Question Since the increase of social media conversations, I noticed that the amount of the comments I receive on this blog is a bit staggering. I receive lots of questions on facebook, twitter or Google+. One of the very interesting questions yesterday was asked on Facebook by Raghavendra. I am re-organizing his script and asking all of the questions he has asked me. Let us see if we could help him with his question: CREATE TABLE #temp (name VARCHAR(100),registered smalldatetime) GO DECLARE @test smalldatetime SET @test=GETDATE() INSERT INTO #temp VALUES ('Value1',@test) INSERT INTO #temp VALUES ('Value2',@test) GO SELECT * FROM #temp ORDER BY registered DESC GO DROP TABLE #temp GO Now when the above script is ran, we will get the following result: Well, the expectation of the query was to have the following result. The row which was inserted last was expected to return as first row in result set as the ORDER BY descending. Side note: Because the requirement is to get the latest data, we can’t use any  column other than smalldatetime column in order by. If we use name column in the order by, we will get an incorrect result as it can be any name. My Initial Reaction My initial reaction was as follows: 1) DataType DateTime2: If file precision of the column is expected from the column which store date and time, it should not be smalldatetime. The precision of the column smalldatetime is One Minute (Read Here) for finer precision use DateTime or DateTime2 data type. Here is the code which includes above suggestion: CREATE TABLE #temp (name VARCHAR(100), registered datetime2) GO DECLARE @test datetime2 SET @test=GETDATE() INSERT INTO #temp VALUES ('Value1',@test) INSERT INTO #temp VALUES ('Value2',@test) GO SELECT * FROM #temp ORDER BY registered DESC GO DROP TABLE #temp GO 2) Tie Breaker Identity: There are always possibilities that two rows were inserted at the same time. In that case, you may need a tie breaker. If you have an increasing identity column, you can use that as a tie breaker as well. CREATE TABLE #temp (ID INT IDENTITY(1,1), name VARCHAR(100),registered datetime2) GO DECLARE @test datetime2 SET @test=GETDATE() INSERT INTO #temp VALUES ('Value1',@test) INSERT INTO #temp VALUES ('Value2',@test) GO SELECT * FROM #temp ORDER BY ID DESC GO DROP TABLE #temp GO Those two were the quick suggestions I provided. It is not necessary that you should use both advices. It is possible that one can use only DATETIME datatype or Identity column can have datatype of BIGINT or have another tie breaker. An Alternate NO Solution In the facebook thread this was also discussed as one of the solutions: CREATE TABLE #temp (name VARCHAR(100),registered smalldatetime) GO DECLARE @test smalldatetime SET @test=GETDATE() INSERT INTO #temp VALUES ('Value1',@test) INSERT INTO #temp VALUES ('Value2',@test) GO SELECT name, registered, ROW_NUMBER() OVER(ORDER BY registered DESC) AS "Row Number" FROM #temp ORDER BY 3 DESC GO DROP TABLE #temp GO However, I believe it is not the solution and can be further misleading if used in a production server. Here is the example of why it is not a good solution: CREATE TABLE #temp (name VARCHAR(100) NOT NULL,registered smalldatetime) GO DECLARE @test smalldatetime SET @test=GETDATE() INSERT INTO #temp VALUES ('Value1',@test) INSERT INTO #temp VALUES ('Value2',@test) GO -- Before Index SELECT name, registered, ROW_NUMBER() OVER(ORDER BY registered DESC) AS "Row Number" FROM #temp ORDER BY 3 DESC GO -- Create Index ALTER TABLE #temp ADD CONSTRAINT [PK_#temp] PRIMARY KEY CLUSTERED (name DESC) GO -- After Index SELECT name, registered, ROW_NUMBER() OVER(ORDER BY registered DESC) AS "Row Number" FROM #temp ORDER BY 3 DESC GO DROP TABLE #temp GO Now let us examine the resultset. You will notice that an index which is created on the base table which is (indeed) schema change the table but can affect the resultset. As you can see, an index can change the resultset, so this method is not yet perfect to get the latest inserted resultset. No Schema Change Requirement After giving these two suggestions, I was waiting for the feedback of the asker. However, the requirement of the asker was there can’t be any schema change because the application was used by many other applications. I validated again, and of course, the requirement is no schema change at all. No addition of the column of change of datatypes of any other columns. There is no further help as well. This is indeed an interesting question. I personally can’t think of any solution which I could provide him given the requirement of no schema change. Can you think of any other solution to this? Need of Database Designer This question once again brings up another ancient question:  “Do we need a database designer?” I often come across databases which are facing major performance problems or have redundant data. Normalization is often ignored when a database is built fast under a very tight deadline. Often I come across a database which has table with unnecessary columns and performance problems. While working as Developer Lead in my earlier jobs, I have seen developers adding columns to tables without anybody’s consent and retrieving them as SELECT *.  There is a lot to discuss on this subject in detail, but for now, let’s discuss the question first. Do you have any suggestions for the above question?
