• How to get a Read-Write Reference to Parent GameObject from a script component attached to it?

  - by onguarde

  I have a game object(object) with a script component(myscript) attached. I have a reference to myscript component through getComponent, and I want to change the transform of the gameObject the script is attached to. myscript.gameObject.transform = (new value); The above code gives me error, Property 'UnityEngine.GameObject.transform' is read only. Is there a way to get a read-write version?

• Building Enterprise Smartphone App &ndash; Part 3: Key Concerns

  - by Tim Murphy

  This is part 3 in a series of posts based on a talk I gave recently at the Chicago Information Technology Architects Group.  Feel free to leave feedback. Keys Concerns Of Smartphones In The Enterprise These are the factors that you need to be aware of and address in order to build successful enterprise smartphone applications.  Most of them have nothing to do with the application itself as you will see here. Managing Devices Managing devices is a factor that is going to effect how much your company will have to spend outside of developing the applications.  How will you track the devices within the corporation?  How often will you have to replace phones and as a consequence have to upgrade your applications to support new phones?  The devices can represent a significant investment of capital.  If these questions are not addressed you will find a number of hidden costs throughout the life of your solution. Purchase or BYOD We have seen the trend of Bring Your Own Device (BYOD) lately within the enterprise.  How many meetings have you been in where someone is on their personal iPad, iPhone, Android phone or Windows Phone?  The issue is if you can afford to support everyone's choice in device? That is a lot to take on even if you only support the current release of each platform. Do you go with the most popular device or do you pick a platform that best matches your current ecosystem and distribute company owned devices?  There is no easy answer here, but you should be able give some dollar value to both hardware and development costs related to platform coverage. Asset Tracking/Insurance Smartphones are devices that are easier to lose or have stolen than laptops and desktops. Not only do you have your normal asset management concerns but also assignment of financial responsibility. You also will need to insure them against damage and theft and add legal documents that spell out the responsibilities of the employees that use these devices. Personal vs. Corporate Data What happens when you terminate an employee?  How do you recover the device?  What happens when they have put personal data on the device?  These are all situation that can cause possible loss of corporate intellectual property or legal repercussions of reclaiming a device with personal data on it.  Policies need to be put in place that protect the company from being exposed to type of loss.  This can mean significant legal and procedural cost that you need to consider. Coming Up In the last installment of this series I will cover application development considerations. del.icio.us Tags: Smartphones,Enterprise Smartphone Apps,Architecture

• MVVM and Animations in Silverlight

  - by Aligned

  I wanted to spin an icon to show progress to my user while some content was downloading. I'm using MVVM (aren't you) and made a satisfactory Storyboard to spin the icon. However, it took longer than expected to trigger that animation from my ViewModel's property.I used a combination of the GoToState action and the DataTrigger from the Microsoft.Expression.Interactions dll as described here.Then I had problems getting it to start until I found this approach that saved the day. The DataTrigger didn't bind right away because "it doesn’t change visual state on load is because the StateTarget property of the GotoStateAction is null at the time the DataTrigger fires.". Here's my XAML, hopefully you can fill in the rest.<Image x:Name="StatusIcon" AutomationProperties.AutomationId="StatusIcon" Width="16" Height="16" Stretch="Fill" Source="inProgress.png" ToolTipService.ToolTip="{Binding StatusTooltip}"> <i:Interaction.Triggers> <utilitiesBehaviors:DataTriggerWhichFiresOnLoad Value="True" Binding="{Binding IsDownloading, Mode=OneWay, TargetNullValue=True}"> <ei:GoToStateAction StateName="Downloading" /> </utilitiesBehaviors:DataTriggerWhichFiresOnLoad> <utilitiesBehaviors:DataTriggerWhichFiresOnLoad Value="False" Binding="{Binding IsDownloading, Mode=OneWay, TargetNullValue=True}"> <ei:GoToStateAction StateName="Complete"/> </utilitiesBehaviors:DataTriggerWhichFiresOnLoad> </i:Interaction.Triggers> <Image.Projection> <PlaneProjection/> </Image.Projection> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="VisualStateGroup"> <VisualStateGroup.Transitions> <VisualTransition GeneratedDuration="0" To="Downloading"> <VisualTransition.GeneratedEasingFunction> <QuadraticEase EasingMode="EaseInOut"/> </VisualTransition.GeneratedEasingFunction> <Storyboard RepeatBehavior="Forever"> <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Projection).(PlaneProjection.RotationZ)" Storyboard.TargetName="StatusIcon"> <EasingDoubleKeyFrame KeyTime="0:0:1.5" Value="-360"/> <EasingDoubleKeyFrame KeyTime="0:0:2" Value="-360"/> </DoubleAnimationUsingKeyFrames> </Storyboard> </VisualTransition> <VisualTransition From="Downloading" GeneratedDuration="0"/> </VisualStateGroup.Transitions> <VisualState x:Name="Downloading"/> <VisualState x:Name="Complete"/> </VisualStateGroup> </VisualStateManager.VisualStateGroups></Image>MVVMAnimations.zip

• WPF4 Unleashed - how does converting child elements work?

  - by Kapol

  In chapter 2 of the book WPF4 Unleashed the author shows an example of how XAML processes type conversion. He states that <SolidColorBrush>White</SolidColorBrush> is equivalent to <SolidColorBrush Color="White"/> , because a string can be converted into a SolidColorBrush object. But how is that enough? It doesn't make sense to me. How does XAML know to which property should the value White be assigned?

• [EF + Oracle] Inserting Data (Sequences) (2/2)

  - by JTorrecilla

  Prologue In the previous chapter we have see how to create DB records with EF, now we are going to Some Questions about Oracle.   ORACLE One characteristic from SQL Server that differs from Oracle is “Identity”. To all that has not worked with SQL Server, this property, that applies to Integer Columns, lets indicate that there is auto increment columns, by that way it will be filled automatically, without writing it on the insert statement. In EF with SQL Server, the properties whose match with Identity columns, will be filled after invoking SaveChanges method. In Oracle DB, there is no Identity Property, but there is something similar. Sequences Sequences are DB objects, that allow to create auto increment, but there are not related directly to a Table. The syntax is as follows: name, min value, max value and begin value. 1: CREATE SEQUENCE nombre_secuencia 2: INCREMENT BY numero_incremento 3: START WITH numero_por_el_que_empezara 4: MAXVALUE valor_maximo | NOMAXVALUE 5: MINVALUE valor_minimo | NOMINVALUE 6: CYCLE | NOCYCLE 7: ORDER | NOORDER 8:    How to get sequence value? To obtain the next val from the sequence: 1: SELECT nb_secuencia.Nextval 2: From Dual Due to there is no direct way to indicate that a column is related to a sequence, there is several ways to imitate the behavior: Use a Trigger (DB), Use Stored Procedures or Functions(…) or my particularly option. EF model, only, imports Table Objects, Stored Procedures or Functions, but not sequences. By that, I decide to create my own extension Method to invoke Next Val from a sequence: 1: public static class EFSequence 2: { 3: public static int GetNextValue(this ObjectContext contexto, string SequenceName) 4: { 5: string Connection = ConfigurationManager.ConnectionStrings["JTorrecillaEntities2"].ConnectionString; 6: Connection=Connection.Substring(Connection.IndexOf(@"connection string=")+19); 7: Connection = Connection.Remove(Connection.Length - 1, 1); 8: using (IDbConnection con = new Oracle.DataAccess.Client.OracleConnection(Connection)) 9: { 10: using (IDbCommand cmd = con.CreateCommand()) 11: { 12: con.Open(); 13: cmd.CommandText = String.Format("Select {0}.nextval from DUAL", SequenceName); 14: return Convert.ToInt32(cmd.ExecuteScalar()); 15: } 16: } 17:  18: } 19: } This Object Context’s extension method are going to invoke a query with the Sequence indicated by parameter. It takes the connection strings from the App settings, removing the meta data, that was created by VS when generated the EF model. And then, returns the next value from the Sequence. The next value of a Sequence is unique, by that, when some concurrent users are going to create records in the DB using the sequence will not get duplicates. This is my own implementation, I know that it could be several ways to do and better ways. If I find any other way, I promise to post it. To use the example is needed to add a reference to the Oracle (ODP.NET) dll.

• Classic vs universal and loss of historical data

  - by iss42

  I'm keen to use some of the new features in Google Universal Analytics. I have an old site though that I don't want to lose the historical data for. The comparisons with historical data are interesting for example. However Google doesn't appear to allow you to change a property from the classic code to the new code. Am I missing something? I'm surprised this isn't a bigger issue for many other users.

• Is the Observer pattern adequate for this kind of scenario?

  - by Omega

  I'm creating a simple game development framework with Ruby. There is a node system. A node is a game entity, and it has position. It can have children nodes (and one parent node). Children are always drawn relatively to their parent. Nodes have a @position field. Anyone can modify it. When such position is modified, the node must update its children accordingly to properly draw them relatively to it. @position contains a Point instance (a class with x and y properties, plus some other useful methods). I need to know when a node's @position's state changes, so I can tell the node to update its children. This is easy if the programmer does something like this: @node.position = Point.new(300,300) Because it is equivalent to calling this: # Code in the Node class def position=(newValue) @position = newValue update_my_children # <--- I know that the position changed end But, I'm lost when this happens: @node.position.x = 300 The only one that knows that the position changed is the Point instance stored in the @position property of the node. But I need the node to be notified! It was at this point that I considered the Observer pattern. Basically, Point is now observable. When a node's position property is given a new Point instance (through the assignment operator), it will stop observing the previous Point it had (if any), and start observing the new one. When a Point instance gets a state change, all observers (the node owning it) will be notified, so now my node can update its children when the position changes. A problem is when this happens: @someNode.position = @anotherNode.position This means that two nodes are observing the same point. If I change one of the node's position, the other would change as well. To fix this, when a position is assigned, I plan to create a new Point instance, copy the passed argument's x and y, and store my newly created point instead of storing the passed one. Another problem I fear is this: somePoint = @node.position somePoint.x = 500 This would, technically, modify @node's position. I'm not sure if anyone would be expecting that behavior. I'm under the impression that people see Point as some kind of primitive rather than an actual object. Is this approach even reasonable? Reasons I'm feeling skeptical: I've heard that the Observer pattern should be used with, well, many observers. Technically, in this scenario there is only one observer at a time. When assigning a node's position as another's (@someNode.position = @anotherNode.position), where I create a whole new instance rather than storing the passed point, it feels hackish, or even inefficient.

• Is this a valid implementation of the repository pattern?

  - by user1578653

  I've been reading up about the repository pattern, with a view to implementing it in my own application. Almost all examples I've found on the internet use some kind of existing framework rather than showing how to implement it 'from scratch'. Here's my first thoughts of how I might implement it - I was wondering if anyone could advise me on whether this is correct? I have two tables, named CONTAINERS and BITS. Each CONTAINER can contain any number of BITs. I represent them as two classes: class Container{ private $bits; private $id; //...and a property for each column in the table... public function __construct(){ $this->bits = array(); } public function addBit($bit){ $this->bits[] = $bit; } //...getters and setters... } class Bit{ //some properties, methods etc... } Each class will have a property for each column in its respective table. I then have a couple of 'repositories' which handle things to do with saving/retrieving these objects from the database: //repository to control saving/retrieving Containers from the database class ContainerRepository{ //inject the bit repository for use later public function __construct($bitRepo){ $this->bitRepo = $bitRepo; } public function getById($id){ //talk directly to Oracle here to all column data into the object //get all the bits in the container $bits = $this->bitRepo->getByContainerId($id); foreach($bits as $bit){ $container->addBit($bit); } //return an instance of Container } public function persist($container){ //talk directly to Oracle here to save it to the database //if its ID is NULL, create a new container in database, otherwise update the existing one //use BitRepository to save each of the Bits inside the Container $bitRepo = $this->bitRepo; foreach($container->bits as $bit){ $bitRepo->persist($bit); } } } //repository to control saving/retrieving Bits from the database class BitRepository{ public function getById($id){} public function getByContainerId($containerId){} public function persist($bit){} } Therefore, the code I would use to get an instance of Container from the database would be: $bitRepo = new BitRepository(); $containerRepo = new ContainerRepository($bitRepo); $container = $containerRepo->getById($id); Or to create a new one and save to the database: $bitRepo = new BitRepository(); $containerRepo = new ContainerRepository($bitRepo); $container = new Container(); $container->setSomeProperty(1); $bit = new Bit(); $container->addBit($bit); $containerRepo->persist($container); Can someone advise me as to whether I have implemented this pattern correctly? Thanks!

• SQL Server 2008 System Functions to Monitor the Instance, Database, Files, etc.

  SQL Server provides several system meta data functions which allow users to obtain property values of different SQL Server objects and securables. Although you can also use the SQL Server catalog views or Dynamic Management Views to obtain much of this information, in some circumstances the system meta data functions simplify the process. In this tip I am going to demonstrate some of the available system meta data functions and their usage in different scenarios.

• IIS7 bulk bindings in vbscript , how to remove a binding

  - by minus4

  I have a script to manage adding over a thousand domains to a single site bindings, this has gone fine, but now client wants about 20 of them removed, Microsoft programmers don't think it would be nice to sort the bindings alphabetically, so does anyone know the code to remove the domains ( array list ) in bulk please. this is what i am using: Set adminManager = createObject("Microsoft.ApplicationHost.WritableAdminManager") adminManager.CommitPath = "MACHINE/WEBROOT/APPHOST" Set sitesSection = adminManager.GetAdminSection("system.applicationHost/sites", "MACHINE/WEBROOT/APPHOST") Set sitesCollection = sitesSection.Collection siteElementPos = FindElement(sitesCollection, "site", Array("name", "microsites")) If siteElementPos = -1 Then WScript.Echo "Element not found!" WScript.Quit End If on error resume next Set siteElement = sitesCollection.Item(siteElementPos) Set bindingsCollection = siteElement.ChildElements.Item("bindings").Collection Dim arrFileNames : arrFileNames = Array("list of domains") Dim objDict : Set objDict = CreateObject("Scripting.Dictionary") Dim strFileName, strTemp For Each strFileName In arrFileNames Set bindingElement = bindingsCollection.CreateNewElement("binding") bindingElement.Properties.Item("protocol").Value = "http" bindingElement.Properties.Item("bindingInformation").Value = "192.168.100.19:80:" & strFileName bindingsCollection.AddElement(bindingElement) Next adminManager.CommitChanges() WScript.Echo "Job Completed" WScript.Quit Function FindElement(collection, elementTagName, valuesToMatch) For i = 0 To CInt(collection.Count) - 1 Set element = collection.Item(i) If element.Name = elementTagName Then matches = True For iVal = 0 To UBound(valuesToMatch) Step 2 Set property = element.GetPropertyByName(valuesToMatch(iVal)) value = property.Value If Not IsNull(value) Then value = CStr(value) End If If Not value = CStr(valuesToMatch(iVal + 1)) Then matches = False Exit For End If Next If matches Then Exit For End If End If Next If matches Then FindElement = i Else FindElement = -1 End If End Function so as you can see it is easy to add, but i can find no code or manual or instructions for the removal. i cant seem to run appcmd either. at first i tried creating a batch file using the appcmd but this never worked, saying appcmd can not be found. thanks

• Install MatroskaProp on Windows 7 x64

  - by Neophytos

  To see more information in Windows Explorer property pages and menus about Matroska Video (.mkv) files, similar to what one can see when selecting native Windows media (.avi, .asf, .wmv or even just plain old mpg) files, Matroska links (from http://www.matroska.org/downloads/windows.html) to a download of the MatroskaProp shell extension (http://www.jory.info/serendipity/archives/14-MatroskaProp-2.8-Released.html). It used to work for me under Windows XP 32-bit. Now I have Windows 7 x64, and downloaded, installed and ran it. Configuration and settings page is fine. But it does not seem to actually register any shell extension. Nothing is added to Explorer windows, menus or property pages when selecting .mkv or .mks files). I tried calling the register hook manually using regsvr32.dll, that again invoked the configuration window and let me set all options, and when confirming even said the registration succeeded, but seems to have had no effect. In the registry I cannot find any traces of the shell extension being installed. Can this extension be made to work under Windows 7 or x64 systems? Are there known problems with installing this or other old shell extensions on x64, or on Windows 7?

• Move database from SQL Server 2012 to 2008

  - by Rich

  I have a database on a SQL Sever 2012 instance which I would like to copy to a 2008 server. The 2008 server cannot restore backups created by a 2012 server (I have tried). I cannot find any options in 2012 to create a 2008 compatible backup. Am I missing something? Is there an easy way to export the schema and data to a version-agnostic format which I can then import into 2008? The database does not use any 2012 specific features. It contains tables, data and stored procedures. Here is what I have tried so far: I tried "tasks" - "generate scripts" on the 2012 server, and I was able to generate the schema (including stored procedures) as a sql script. This didn't include any of the data, though. After creating that schema on my 2008 machine, I was able to open the "Export Data" wizard on the 2012 machine, and after configuring the 2012 as source machine and the 2008 as target machine, I was presented with a list of tables which I could copy. I selected all my tables (300+), and clicked through the wizard. Unfortunately it spends ages generating its scripts, then fails with errors like "Failure inserting into the read-only column 'FOO_ID'". I also tried the "Copy Database Wizard", which claimed to be able to copy "from 2000 or later to 2005 or later". It has two modes: 1) "detach and attach", which failed with error: Message: Index was outside the bounds of the array. StackTrace: at Microsoft.SqlServer.Management.Smo.PropertyBag.SetValue(Int32 index, Object value) ... at Microsoft.SqlServer.Management.Smo.DataFile.get_FileName() 2) SQL Management Object Method which failed with error "Cannot read property IsFileStream.This property is not available on SQL Server 7.0."

• unreadable corrupted ntfs partition - lost clusters reported

  - by Eduardo Martinez

  partition magic is reporting multiple 'bad file record signature' and 'lost clusters' errors on my 250GB samsung sata disk (connected via usb on a xp sp3). Unfortunately PM is unable to fix. PM shows the drive as being NTFS, detects used space ok and also drive name. But PM browser (right click on partition, browse...) won't show anything (as if disk was empty) Windows Explorer is not even picking the drive name and reports 'the file or directory is corrupted and unreadable' PTDD partition table doctor demo tells me the boot sector is fine, and I can see all disk content on its browser - but crucially cannot copy that content over to a new disk (PTDD browser is pretty arid to say the least) Also tried - photorec-6.11.3 - it actually started to extract files but wouldn't keep file names or any folder structure (maybe I missed sth on the configuration options) - find and mount - intellectual scan went well, the only partition on the disk was detected, then tried to mount into p: but got this error on windows explorer: 'p:\ is not accesible. The media is write protected'. Find and mount allows you to create an image from partition but I don't have a disk big enough at hand. Does anyone know if this will keep the extracted files/folders structure intact? I'm starting to think the disk is pretty screwed and my chances to recover this data are slim. Please someone enlighten me with that marvellous piece of software I am missing :-) Thanks in advance

• Configure Windows firewall to prevent an application from listening on a specific port

  - by U-D13

  The issue: there are many applications struggling to listen on port 80 (Skype, Teamviewer et al.), and to many of them that even is not essential (in the sense that you can have a httpd running and blocking the http port, and the other application won't even squeak about being unable to open the port). What makes things worse, some of the apps are... Well, I suppose, that it's okay that the mentally impaired are being integrated in the society by giving them a job to do, but... Programming requires some intellectual effort, in my humble opinion... What I mean is that there is no way to configure the app not to use specific ports (that's what you get for using proprietary software) - you can either add it to windows firewall exceptions (and succumb to undesired port opening behavior) or not (and risk losing most - if not all - of the functionality). Technically, it is not impossible for the firewall to deny an application opening an incoming port even if the application is in the exception list. And if this functionality is built into the Windows firewall somewhere, there should be a way to activate it. So, what I want to know is: whether there exists such an option, and if it does how to activate it.

• JBoss7 load balancing with mod_proxy_balancer - session not working

  I am trying to set up mod_proxy_balancer for routing requests to 2 jboss7-servers. For the time being I am testing this setup on my local machine, using following config in httpd.conf: ProxyRequests Off <Proxy \*> Order deny,allow Deny from all </Proxy> ProxyPass / balancer://mycluster/ stickysession=JSESSIONID|jsessionid scolonpathdelim=On <Proxy balancer://mycluster> BalancerMember http://localhost:8080 route=node1 BalancerMember http://localhost:8081 route=node2 Order allow,deny Allow from all </Proxy> and in the standalone.xml file of each jboss I have defined the jvmRoute system property: <system-properties> <property name="jvmRoute" value="node1"/> </system-properties> At http:// localhost/myapp the application is accessible but the java-session is not build up correctly. Consequently the authentication is not working. The funny thing is, that everything is working if I turn off one JBoss-instance. As I have tried a couple of settings already, I am thankful for any further suggestions.

• Word 2013 can't compare readonly files

  - by Moshe Katz

  I am using Tortoise SVN to work with a repository that contains some documentation saved as Word documents. On my old computer, with Office 2010, I was able to compare with previous revisions. Tortoise would open Word in compare view so I could see the differences between the files. I have installed Office 2013 (final version from Technet, not the preview version) on my new laptop for testing and now I can no longer compare Word Documents. Tortoise pops up a generic error that it was unable to compare the two files. Tortoise uses a JScript file to interface with Word, so I ran that file through a debugger and found that the actual error is: The Compare method or property is not available because this command is not available for reading. Some Googling followed by some testing revealed that the error is caused by the first file opened (in this case, the previous version) being opened as Read-Only. If I change the JScript code to open in normal mode, and I find the file on the system and un-check the "Read Only" property (if necessary), then the comparison opens as expected. I was unable to find any documentation about this change to Word on any Microsoft site. Does anyone know why this has been changed, and if it is intentional and not a bug, what the benefit is of requiring the file to be writable in order to compare it with another? Note: This is tagged word-2013-preview but it is actually for the release version of Word that is available on MSDN and Technet. I do not have enough rep. on this site to create new tags (yet).

• How do I configure permissions for a cluster share using Powershell on 2008?

  - by Andrew J. Brehm

  I have a cluster resource of type "file share" but when I try to configure the "security" parameter I get the following error (excerpt): Set-ClusterParameter : Parameter 'security' does not exist on the cluster object Using cluster.exe I get a better result, namely the usual nothing when the command worked. But when I check in Failover Cluster Manager the permissions have not changed. In Server 2003 the cluster.exe method worked. Any ideas? Update: Entire command and error. PS C:\> $resource=get-clusterresource testshare PS C:\> $resource Name State Group ResourceType ---- ----- ----- ------------ testshare Offline Test File Share PS C:\> $resource|set-clusterparameter security "domain\account,grant,f" Set-ClusterParameter : Parameter 'security' does not exist on the cluster object 'testshare'. If you are trying to upda te an existing parameter, please make sure the parameter name is specified correctly. You can check for the current par ameters by passing the .NET object received from the appropriate Get-Cluster* cmdlet to "| Get-ClusterParameter". If yo u are trying to update a common property on the cluster object, you should set the property directly on the .NET object received by the appropriate Get-Cluster* cmdlet. You can check for the current common properties by passing the .NET o bject received from the appropriate Get-Cluster* cmdlet to "| fl *". If you are trying to create a new unknown paramete r, please use -Create with this Set-ClusterParameter cmdlet. At line:1 char:31 + $resource|set-clusterparameter <<<< security "domain\account,grant,f" + CategoryInfo : NotSpecified: (:) [Set-ClusterParameter], ClusterCmdletException + FullyQualifiedErrorId : Set-ClusterParameter,Microsoft.FailoverClusters.PowerShell.SetClusterParameterCommand

• Why is SMF manifest losing configuration data when exported on SmartOS?

  - by Scott Lowe

  I'm running a server process under SMF (Server Management Facility) on Joyent's Base64 1.8.1 SmartOS image. For those not aqauinted with SmartOS, it is a cloud-based distribution of IllumOS with KVM. But essentially it is like Solaris and inherits from OpenSolaris. So even if you've not used SmartOS, I'm hoping to tap into some Solaris knowledge on ServerFault. My issue is that I want an unprivileged user to be allowed to restart a service that they own. I have worked out how to do that by using RBAC and adding an authorisation to /etc/security/auth_attr and associating that authorisation with my user. I then added the following to my SMF manifest for the service: <property_group name='general' type='framework'> <!-- Allow to be restarted--> <propval name='action_authorization' type='astring' value='solaris.smf.manage.my-server-process' /> <!-- Allow to be started and stopped --> <propval name='value_authorization' type='astring' value='solaris.smf.manage.my-server-process' /> </property_group> And this works well when imported. My unprivileged user is allowed to restart, start and stop its own server process (this is for automated code deployments). However, if I export the SMF manifest, this configuration data is gone... all I see in that section is this: <property_group name='general' type='framework'> <property name='action_authorization' type='astring'/> <property name='value_authorization' type='astring'/> </property_group> Does anybody know why this is happening? Is my syntax wrong, or am I simply not using SMF incorrectly?

• Windows Server task manager displays much higher memory use than sum of all processes' working set s

  - by Sleepless

  I have a 16 GB Windows Server 2008 x64 machine mostly running SQL Server 2008. The free memory as seen in Task Manager is very low (128 MB at the moment), i.e. about 15.7 GB are used. So far, so good. Now when I try to narrow down the process(es) using the most memory I get confused: None of the processes have more than 200MB Working Set Size as displayed in the 'Processes' tab of Task Manager. Well, maybe the Working Set Size isn't the relevant counter? To figure that out I used a PowerShell command [1] to sum up each individual property of the process object in sort of a brute force approach - surely one of them must add up to the 15.7 GB, right? Turns out none of them does, with the closest being VirtualMemorySize (around 12.7 GB) and PeakVirtualMemorySize (around 14.7 GB). WTF? To put it another way: Which of the numerous memory related process information is the "correct" one, i.e. counts towards the server's physical memory as displayed in the Task Manager's 'Performance' tab? Thank you all!
