Configuring LiveID authentication with SharePoint2010

- by ybbest

With the addition of the new claims based authentication framework in SharePoint 2010, SharePoint is now more loosely coupled to the authentication layer than ever. You’ve probably seen presentations or webinars where it was mentioned that you can use claims authentication against authentication providers such as Live ID and OpenID. In this blog I will show you the common problems while you configure you LiveID integration with SharePoint2010.The detailed configuration can be found in the following blogs. Part 1 – http://www.wictorwilen.se/Post/Visual-guide-to-Windows-Live-ID-authentication-with-SharePoint-2010-part-1.aspx Part 2 – http://www.wictorwilen.se/Post/Visual-guide-to-Windows-Live-ID-authentication-with-SharePoint-2010-part-2.aspx Part 3 – http://www.wictorwilen.se/Post/Visual-guide-to-Windows-Live-ID-authentication-with-SharePoint-2010-part-3.aspx Here are some problems I have following the instructions: Problem 1: If you had the following exceptions when you run the PowerShell scripts to create the new LiveID authentication provider New-SPTrustedIdentityTokenIssuer : Exception of type ‘System.ArgumentException’ was thrown.Parameter name: claimType At line:1 char:42 + $authp = New-SPTrustedIdentityTokenIssuer <<<< -Name “LiveID INT” -Description “LiveID INT” -Realm $realm -ImportTrustCertificate $certfile -ClaimsMappings $emailclaim,$upnclaim -SignInUrl “https://login.live-int.com/login.srf” -IdentifierClaim $emailclaim.InputClaimType + CategoryInfo : InvalidData:(Microsoft.Share…dentityProvider:SPCmdletNewSPIdentityProvider) [New-SPTrustedIdentityTokenIssuer], ArgumentException + FullyQualifiedErrorId :Microsoft.SharePoint.PowerShell.SPCmdletNewSPIdentityProvider Solution: You need to Remove the existing the SPTrustedIdentityTokenIssuer. 1. You need to first get the existing TokenIssuer name by Get-SPTrustedIdentityTokenIssuer, and then run Remove- SPTrustedIdentityTokenIssuer to remove the existing TokenIssuer. 2. After that , you can re-run the script , everything should work fine now. Problem 2: Live INT automatically logs out Whenever I try to log in (https://login.live-int.com/login.srf), after entering valid email/password I get redirected to the logout page. Solution: You can find the solution in my previous blog.

Entity Object Based on PL/SQL

- by Manoj Madhusoodanan

This blog describes how to create a PL/SQL based Entity Object.Oracle application has number of APIs and each API will perform numerous number of tasks.We can create PL/SQL based EO which will directly invoke the PL/SQL stored procedure from the EO. Here I am demonstrating using a standard API FND_USER_PKG.CREATEUSER.This API has x_user_name and x_owner as mandatory parameter.My task is to create a user through OAF page which will accept User Name and Password. Following steps needs to be performed to achieve the above scenario. 1) Create FndUserEO as follows Include all the API parameters and WHO columns in the EO. Make UserName and EncryptedUserPassword ( Here I am not using Encrypted Password. The column name is same as table column so I am keeping the same) column as mandatory. Generate VO. 2) Edit FndUserEOImpl and add the following 3) Attach FndUserVO to AM 4) Create the UI 5) Deploy following files to middle tier and restart the server. Entity Object: xxcust.oracle.apps.fnd.user.schema.server.FndUserEO.xml xxcust.oracle.apps.fnd.user.schema.server.FndUserEOImpl.java View Object: xxcust.oracle.apps.fnd.user.server.FndUserVO.xml xxcust.oracle.apps.fnd.user.server.FndUserVOImpl.javaUser Interface: xxcust.oracle.apps.fnd.user.webui.CreateFndUserCO.java xxcust.oracle.apps.fnd.user.webui.CreateFndUserPG.xmlYou can test by giving User Name and Password.

Multiple audio sources on a single gameObject in unity

- by angryInsomniac

So, I have an audio system set up wherein I have loaded all my audio clips centrally and play them on demand by passing the requesting audioSource into the sound manager. However, there is a complication wherein if I want to overlay multiple looping sounds, I need to have multiple audio sources on an object, which is fine , so I created two in my script instantiated them and played my clips on them and then the world went crazy. For some reason, when I create two audio Sources in an object only the latest one is ever used, even if I explicitly keep objects separated, playing a clip on one or the other plays the clip on the last one that was created, furthermore, either this last one is not created in the right place or somehow messes with the rolloff rules because I can hear it all across my level, havign just one source works fine, but putting a second one on it causes shit to go batshit insane. Does anyone know the reason / solution for this ? Some pseudocode : guardSoundsSource = (AudioSource)gameObject.AddComponent("AudioSource"); guardSoundsSource.name = "Guard_Sounds_source"; // Setup this source guardThrusterSource = (AudioSource)gameObject.AddComponent("AudioSource"); guardThrusterSource.name = "Guard_Thruster_Source"; // setup this source // play using custom Sound manager soundMan.soundMgr.playOnSource(guardSoundsSource,"Guard_Idle_loop" ,true,GameManager.Manager.PlayerType); // this method prints out the name of the source the sound was to be played on and it always shows "Guard_Thruster_Source" even on the "Guard_Idle_loop" even though I clearly told it to use "Guard_Sounds_source"

Oracle Enterprise Manager 12c Configuration Best Practices (Part 3 of 3)

- by Bethany Lapaglia

<span id="XinhaEditingPostion"></span>&lt;span id=&quot;XinhaEditingPostion&quot;&gt;&lt;/span&gt;&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;span id=&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;XinhaEditingPostion&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;/span&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt; This is part 3 of a three-part blog series that summarizes the most commonly implemented configuration changes to improve performance and operation of a large Enterprise Manager 12c environment. A “large” environment is categorized by the number of agents, targets and users. See the Oracle Enterprise Manager Cloud Control Advanced Installation and Configuration Guide chapter on Sizing for more details on sizing your environment properly. Part 1 of this series covered recommended configuration changes for the OMS and Repository Part 2 covered recommended changes for the Weblogic server Part 3 covers general configuration recommendations and a few known issues The entire series can be found in the My Oracle Support note titled Oracle Enterprise Manager 12c Configuration Best Practices [1553342.1]. Configuration Recommendations Configure E-Mail Notifications for EM related Alerts In some environments, the notifications for events for different target types may be sent to different support teams (i.e. notifications on host targets may be sent to a platform support team). However, the EM application administrators should be well informed of any alerts or problems seen on the EM infrastructure components. Recommendation: Create a new Incident rule for monitoring all EM components and setup the notifications to be sent to the EM administrator(s). The notification methods available can create or update an incident, send an email or forward to an event connector. To setup the incident rule set follow the steps below. Note that each individual rule in the rule set can have different actions configured. 1. To create an incident rule for monitoring the EM components, click on Setup / Incidents / Incident Rules. On the All Enterprise Rules page, click on the out-of-box rule called “Incident management Ruleset for all targets” and then click on the Actions drop down list and select “Create Like Rule Set…” 2. For the rule set name, enter a name such as MTM Ruleset. Under the Targets tab, select “All targets of types” and select “OMS and Repository” from the drop down list. This target type contains all of the key EM components (OMS servers, repository, domains, etc.) 3. Click on the Rules tab. To edit a rule, click on the rule name and click on Edit as seen below 4. Modify the following rules: a. Incident creation Rule for metric alerts i. Leave the Type set as is but change the Severity to add Warning by clicking on the drop down list and selecting “Warning”. Click Next. ii. Add or modify the actions as required (i.e. add email notifications). Click Continue and then click Next. iii. Leave the Name and description the same and click Next. iv. Click Continue on the Review page. b. Incident creation Rule for target unreachable. i. Leave the Type set as is but change the Target type to add OMS and Repository by clicking on the drop down list selecting “OMS and Repository”. Click Next. ii. Add or modify the actions as required (i.e. add email notifications) Click Continue and then click Next. iii. Leave the Name and description the same and click Next. iv. Click Continue on the Review page. 5. Modify the actions for any other rule as required and be sure to click the “Save” push button to save the rule set or all changes will be lost. Configure Out-of-Band Notifications for EM Agent Out-of-Band notifications act as a backup when there’s a complete EM outage or a repository database issue. This is configured on the agent of the OMS server and can be used to send emails or execute another script that would create a trouble ticket. It will send notifications about the following issues: • Repository Database down • All OMS are down • Repository side collection job that is broken or has an invalid schedule • Notification job that is broken or has an invalid schedule Recommendation: To setup Out-of-Band Notifications, refer to the MOS note “How To Setup Out Of Bound Email Notification In 12c” (Doc ID 1472854.1) Modify the Performance Test for the EM Console Service The EM Console Service has an out-of-box defined performance test that will be run to determine the status of this service. The test issues a request via an HTTP method to a specific URL. By default, the HTTP method used for this test is a GET but for performance reasons, should be changed to HEAD. The URL used for this request is set to point to a specific OMS server by default. If a multi-OMS system has been implemented and the OMS servers are behind a load balancer, then the URL in this section must be modified to point to the load balancer name instead of a specific server name. If this is not done and a portion of the infrastructure is down then the EM Console Service will show down as this test will fail. Recommendation: Modify the HTTP Method for the EM Console Service test and the URL if required following the detailed steps below. 1. To create an incident rule for monitoring the EM components, click on Targets / Services. From the list of services, click on the EM Console Service. 2. On the EM Console Service page, click on the Test Performance tab. 3. At the bottom of the page, click on the Web Transaction test called EM Console Service Test 4. Click on the Service Tests and Beacons breadcrumb near the top of the page. 5. Under the Service Tests section, make sure the EM Console Service Test is selected and click on the Edit push button. 6. Under the Transaction section, make sure the Access Logout page transaction is selected and click on the Edit push button 7) Under the Request section, change the HTTP Method from the default of GET to the recommended value of HEAD. The URL in this section must be modified to point to the load balancer name instead of a specific server name if multi-OMSes have been implemented. Check for Known Issues Job Purge Repository Job is Shown as Down This issue is caused after upgrading EM from 12c to 12cR2. On the Repository page under Setup ? Manage Cloud Control ? Repository, the job called “Job Purge” is shown as down and the Next Scheduled Run is blank. Also, repvfy reports that this is a missing DBMS_SCHEDULER job. Recommendation: In EM 12cR2, the apply_purge_policies have been moved from the MGMT_JOB_ENGINE package to the EM_JOB_PURGE package. To remove this error, execute the commands below: $ repvfy verify core -test 2 -fix To confirm that the issue resolved, execute $ repvfy verify core -test 2 It can also be verified by refreshing the Job Service page in EM and check the status of the job, it should now be Up. Configure the Listener Targets in EM with the Listener Password (where required) EM will report this error every time it is encountered in the listener log file. In a RAC environment, typically the grid home and rdbms homes are owned by different OS users. The listener always runs from the grid home. Only the listener process owner can query or change the listener properties. The listener uses a password to allow other OS users (ex. the agent user) to query the listener process for parameters. EM has a default listener target metric that will query these properties. If the agent is not permitted to do this, the TNS incident (TNS-1190) will be logged in the listener’s log file. This means that the listener targets in EM also need to have this password set. Not doing so will cause many TNS incidents (TNS-1190). Below is a sample of this error from the listener log file: Recommendation: Set a listener password and include it in the configuration of the listener targets in EM For steps on setting the listener passwords, see MOS notes: 260986.1 , 427422.1

Creating packages in code - Workflow

This is just a quick one prompted by a question on the SSIS Forum, how to programmatically add a precedence constraint (aka workflow) between two tasks. To keep the code simple I’ve actually used two Sequence containers which are often used as anchor points for a constraint. Very often this is when you have task that you wish to conditionally execute based on an expression. If it the first or only task in the package you need somewhere to anchor the constraint too, so you can then set the expression on it and control the flow of execution. Anyway, back to my code sample, here’s a quick screenshot of the finished article: Now for the code, which is actually pretty simple and hopefully the comments should explain exactly what is going on. Package package = new Package(); package.Name = "SequenceWorkflow"; // Add the two sequence containers to provide anchor points for the constraint // If you use tasks, it follows exactly the same pattern, they all derive from Executable Sequence sequence1 = package.Executables.Add("STOCK:Sequence") as Sequence; sequence1.Name = "SEQ Start"; Sequence sequence2 = package.Executables.Add("STOCK:Sequence") as Sequence; sequence2.Name = "SEQ End"; // Add the precedence constraint, here we use the package's constraint collection // as it hosts the two objects we want to constrain (link) // The default constraint is a basic On Success constraint just like in the designer PrecedenceConstraint constraint = package.PrecedenceConstraints.Add(sequence1, sequence2); // Change the settings to use a (dummy) expression only constraint.EvalOp = DTSPrecedenceEvalOp.Expression; constraint.Expression = "1 == 1"; The complete code file is available to download below.

Clusterware 11gR2 – Setting up an Active/Passive failover configuration

- by Gilles Haro

Oracle provides many interesting ways to ensure High Availability. Dataguard configurations, RAC configurations or even both (as recommended for a Maximum Available Architecture - MAA) are the most frequently found. But when it comes to protecting a system with an Active/Passive architecture with failover capabilities, one often thinks to expensive third party cluster systems. Oracle Clusterware technology, which comes free with Oracle Database, is – in the knowing of most people - often linked to Oracle RAC and therefore, is rarely used to implement failover solutions. 11gR2 Clusterware – which is part of Oracle Grid Infrastructure - provides a comprehensive framework to setup automatic failover configurations. It is actually possible to make “failover-able'” and, therefore to protect, almost every kind of application (from xclock to the more complex Application Server) In the next couple of lines, I will try to present the different steps to achieve this goal : Have a fully operational 11gR2 database protected by automatic failover capabilities. I assume you are fluent in installing Oracle Database 11gR2, Oracle Grid Infrastructure 11gR2 on a Linux system and that ASM is not a problem for you (as I am using it as a shared storage). If not, please have a look at Oracle Documentation. As often, I made my tests using an Oracle VirtualBox environment. The scripts are tested and functional. Unfortunately, there can always be a typo or a mistake. This blog entry is not a course around the Clusterware Framework. I just hope it will let you see how powerful it is and that it will give you the whilst to go further with it… Prerequisite 2 Linux boxes (OELCluster01 and OELCluster02) at the same OS level. I used OEL 5 Update 5 with Enterprise Kernel. Shared Storage (SAN). On my VirtualBox system, I used Openfiler to simulate the SAN Oracle 11gR2 Database (11.2.0.1) Oracle 11gR2 Grid Infrastructure (11.2.0.1) Step 1 – Install the software Using asmlib, create 3 ASM disks (ASM_CRS, ASM_DTA and ASM_FRA) Install Grid Infrastructure for a cluster (OELCluster01 and OELCluster02 are the 2 nodes of the cluster) Use ASM_CRS to store Voting Disk and OCR. Use SCAN. Install Oracle Database Standalone binaries on both nodes. Use asmca to check/mount the disk groups on 2 nodes Use dbca to create and configure a database on the primary node Let’s name it DB11G. Copy the pfile, password file to the second node. Create adump directoty on the second node. Step 2 - Setup the resource to be protected After its creation with dbca, the database is automatically protected by the Oracle Restart technology available with Grid Infrastructure. Consequently, it restarts automatically (if possible) after a crash (ex: kill –9 smon). A database resource has been created for that in the Cluster Registry. We can observe this with the command : crsctl status resource that shows and ora.dba11g.db entry. Let’s save the definition of this resource, for future use : mkdir –p /crs/11.2.0/HA_scripts chown oracle:oinstall /crs/11.2.0/HA_scripts crsctl status resource ora.db11g.db -p > /crs/11.2.0/HA_scripts/myResource.txt Although very interesting, Oracle Restart is not cluster aware and cannot restart the database on any other node of the cluster. So, let’s remove it from the OCR definitions, we don’t need it ! srvctl stop database -d DB11G srvctl remove database -d DB11G Instead of it, we need to create a new resource of a more general type : cluster_resource. Here are the steps to achieve this : Create an action script : /crs/11.2.0/HA_scripts/my_ActivePassive_Cluster.sh #!/bin/bash export ORACLE_HOME=/oracle/product/11.2.0/dbhome_1 export ORACLE_SID=DB11G case $1 in 'start') $ORACLE_HOME/bin/sqlplus /nolog <<EOF connect / as sysdba startup EOF RET=0 ;; 'stop') $ORACLE_HOME/bin/sqlplus /nolog <<EOF connect / as sysdba shutdown immediate EOF RET=0 ;; 'check') ok=`ps -ef | grep smon | grep $ORACLE_SID | wc -l` if [ $ok = 0 ]; then RET=1 else RET=0 fi ;; '*') RET=0 ;; esac if [ $RET -eq 0 ]; then exit 0 else exit 1 fi This script must provide, at least, methods to start, stop and check the database. It is self-explaining and contains nothing special. Just be aware that it is run as Oracle user (because of the ACL property – see later) and needs to know about the environment. It also needs to be present on every node of the cluster. chmod +x /crs/11.2.0/HA_scripts/my_ActivePassive_Cluster.sh scp /crs/11.2.0/HA_scripts/my_ActivePassive_Cluster.sh oracle@OELCluster02:/crs/11.2.0/HA_scripts Create a new resource file, based on the information we got from previous myResource.txt . Name it myNewResource.txt. myResource.txt is shown below. As we can see, it defines an ora.database.type resource, named ora.db11g.db. A lot of properties are related to this type of resource and do not need to be used for a cluster_resource.

Take care of the resource type. It needs to be a cluster_resource and not a ora.database.type resource (Oracle recommendation) . crsctl add resource DB11G.db -type cluster_resource -file /crs/11.2.0/HA_scripts/myNewResource.txt Step 3 - Start the resource crsctl start resource DB11G.db This command launches the ACTION_SCRIPT with a start and a check parameter on the primary node of the cluster. Step 4 - Test this We will test the setup using 2 methods. crsctl relocate resource DB11G.db This command calls the ACTION_SCRIPT (on the two nodes) to stop the database on the active node and start it on the other node. Once done, we can revert back to the original node, but, this time we can use a more “MS$ like” method :Turn off the server on which the database is running. After short delay, you should observe that the database is relocated on node 1. Conclusion Once the software installed and the standalone database created (which is a rather common and usual task), the steps to reach the objective are quite easy : Create an executable action script on every node of the cluster. Create a resource file. Create/Register the resource with OCR using the resource file. Start the resource. This solution is a very interesting alternative to licensable third party solutions.

Is there a way to display navmesh agent path in Unity?

- by Antoine Guillien

I'm currently making a prototype for a game I plan to develop. As far as I did, I managed to set up the navigation mesh and my navmeshagents. I would like to display the path they are following when setDestination() is fired. I did some researches but didn't find anything about it. EDIT 1 : So I instantiate an empty object with a LineRenderer and I have a line bewteen my agent and the destination. Still I've not all the points when the path has to avoid an obstacle. Furthermore, I wonder if the agent.path does reflect the real path that the agent take as I noticed that it actually follow a "smoothier" path. Here is the code so far : GameObject container = new GameObject(); container.transform.parent = agent.gameObject.transform; LineRenderer ligne = container.AddComponent<LineRenderer>(); ligne.SetColors(Color.white,Color.white); ligne.SetWidth(0.1f,0.1f); //Get def material ligne.gameObject.renderer.material.color = Color.white; ligne.gameObject.renderer.material.shader = Shader.Find("Sprites/Default"); ligne.gameObject.AddComponent<LineScript>(); ligne.SetVertexCount(agent.path.corners.Length+1); int i = 0; foreach(Vector3 v in p.corners) { ligne.SetPosition(i,v); //Debug.Log("position agent"+g.transform.position); //Debug.Log("position corner = "+v); i++; } ligne.SetPosition(p.corners.Length,agent.destination); ligne.gameObject.tag = "ligne"; So How can I get the real coordinates my agent is going to walk throught ?

Intercept method calls in Groovy for automatic type conversion

- by kerry

One of the cooler things you can do with groovy is automatic type conversion. If you want to convert an object to another type, many times all you have to do is invoke the ‘as’ keyword: def letters = 'abcdefghijklmnopqrstuvwxyz' as List But, what if you are wanting to do something a little fancier, like converting a String to a Date? def christmas = '12-25-2010' as Date ERROR org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object '12-25-2010' with class java.lang.String' to class 'java.util.Date' No bueno! I want to be able to do custom type conversions so that my application can do a simple String to Date conversion. Enter the metaMethod. You can intercept method calls in Groovy using the following method: def intercept(name, params, closure) { def original = from.metaClass.getMetaMethod(name, params) from.metaClass[name] = { Class clazz -> closure() original.doMethodInvoke(delegate, clazz) } } Using this method, and a little syntactic sugar, we create the following ‘Convert’ class: // Convert.from( String ).to( Date ).using { } class Convert { private from private to private Convert(clazz) { from = clazz } static def from(clazz) { new Convert(clazz) } def to(clazz) { to = clazz return this } def using(closure) { def originalAsType = from.metaClass.getMetaMethod('asType', [] as Class[]) from.metaClass.asType = { Class clazz -> if( clazz == to ) { closure.setProperty('value', delegate) closure(delegate) } else { originalAsType.doMethodInvoke(delegate, clazz) } } } } Now, we can make the following statement to add the automatic date conversion: Convert.from( String ).to( Date ).using { new java.text.SimpleDateFormat('MM-dd-yyyy').parse(value) } def christmas = '12-25-2010' as Date Groovy baby!

Aggregating Excel cell contents that match a label [migrated]

- by Josh

I'm sure this isn't a terribly difficult thing, but it's not the type of question that easily lends itself to internet searches. I've been assigned a project for work involving a complex spreadsheet. I've done the usual =SUM and other basic Excel formulas, and I've got enough coding background that I'm able to at least fudge my way through VBA, but I'm not certain how to proceed with one part of the task. Simple version: On Sheet 1 I have a list of people (one on each row, person's name in column A), on sheet 2 I have a list of groups (one on each row, group name in column A). Each name in Sheet 1 has its own row, and I have a "Data Validation" dropdown menu where you choose the group each person belongs to. That dropdown is sourced from Sheet 2, where each group has a row. So essentially the data validation source for Sheet 1's "Group" column is just "=Sheet2!$a1:a100" or whatever. The problem is this: I want each group row in Sheet 2 to have a formula which results in a list of all the users which have been assigned to that group on Sheet 1. What I mean is something the equivalent of "select * from PeopleTab where GROUP = ThisGroup". The resulting cell would just stick the names together like "Bob Smith, Joe Jones, Sally Sanderson" I've been Googling for hours but I can't think of a way to phrase my search query to get the results I want. Here's an example of desired result (Dash-delimited. Can't find a way to make it look nice, table tags don't seem to work here): (Sheet 1) Bob Smith - Group 1 (selected from dropdown) Joe Jones - Group 2 (selected from dropdown) Sally Sanderson - Group 1 (selected from dropdown) (Sheet 2) Group 1 - Bob Smith, Sally Sanderson (result of formula) Group 2 - Joe Jones (result of formula) What formula (or even what function) do I use on that second column of sheet 2 to make a flat list out of the members of that group?

Are very short or abbreviated method/function names that don't use full words bad practice or a matter of style.

- by Alb

Is there nowadays any case for brevity over clarity with method names? Tonight I came across the Python method repr() which seems like a bad name for a method to me. It's not an English word. It apparently is an abbreviation of 'representation' and even if you can deduce that, it still doesn't tell you what the method does. A good method name is subjective to a certain degree, but I had assumed that modern best practices agreed that names should be at least full words and descriptive enough to reveal enough about the method that you would easily find one when looking for it. Method names made from words help let your code read like English. repr() seems to have no advantages as a name other than being short and IDE auto-complete makes this a non-issue. An additional reason given in an answer is that python names are brief so that you can do many things on one line. Surely the better way is to just extract the many things to their own function, and repeat until lines are not too long. Are these just a hangover from the unix way of doing things? Commands with names like ls, rm, ps and du (if you could call those names) were hard to find and hard to remember. I know that the everyday usage of commands such as these is different than methods in code so the matter of whether those are bad names is a different matter.

Adding Suggestions to the SharePoint 2010 Search Programatically

- by Ricardo Peres

There are numerous pages that show how to do this with PowerShell, but I found none on how to do it with plain old C#, so here it goes! To abbreviate, I wanted to have SharePoint suggest the site collection user’s names after the first letters are filled in a search site’s search box. Here’s how I did it: 1: //get the Search Service Application (replace with your own name) 2: SearchServiceApplication searchApp = farm.Services.GetValue<SearchQueryAndSiteSettingsService>().Applications.GetValue<SearchServiceApplication>("Search Service Application") as SearchServiceApplication; 3: 4: Ranking ranking = new Ranking(searchApp); 5: 6: //replace EN-US with your language of choice 7: LanguageResourcePhraseList suggestions = ranking.LanguageResources["EN-US"].QuerySuggestionsAlwaysSuggestList; 8: 9: foreach (SPUser user in rootWeb.Users) 10: { 11: suggestions.AddPhrase(user.Name, String.Empty); 12: } 13: 14: //get the job that processes suggestions and run it 15: SPJobDefinition job = SPFarm.Local.Services.OfType<SearchService>().SelectMany(x => x.JobDefinitions).Where(x => x.Name == "Prepare query suggestions").Single(); 16: job.RunNow(); You may do this, for example, on a feature. Of course, feel free to change users for something else, all suggestions are treated as pure text.

SQL SERVER – Follow up – Usage of $rowguid and $IDENTITY

- by pinaldave

The most common question I often receive is why do I blog? The answer is even simpler – I blog because I get an extremely constructive comment and conversation from people like DHall and Kumar Harsh. Earlier this week, I shared a conversation between Madhivanan and myself regarding how to find out if a table uses ROWGUID or not? I encourage all of you to read the conversation here: SQL SERVER – Identifying Column Data Type of uniqueidentifier without Querying System Tables. In simple words the conversation between Madhivanan and myself brought out a simple query which returns the values of the UNIQUEIDENTIFIER without knowing the name of the column. David Hall wrote few excellent comments as a follow up and every SQL Enthusiast must read them first, second and third. David is always with positive energy, he first of all shows the limitation of my solution here and here which he follows up with his own solution here. As he said his solution is also not perfect but it indeed leaves learning bites for all of us – worth reading if you are interested in unorthodox solutions. Kumar Harsh suggested that one can also find Identity Column used in the table very similar way using $IDENTITY. Here is how one can do the same. DECLARE @t TABLE ( GuidCol UNIQUEIDENTIFIER DEFAULT newsequentialid() ROWGUIDCOL, IDENTITYCL INT IDENTITY(1,1), data VARCHAR(60) ) INSERT INTO @t (data) SELECT 'test' INSERT INTO @t (data) SELECT 'test1' SELECT $rowguid,$IDENTITY FROM @t There are alternate ways also to find an identity column in the database as well. Following query will give a list of all column names with their corresponding tablename. SELECT SCHEMA_NAME(so.schema_id) SchemaName, so.name TableName, sc.name ColumnName FROM sys.objects so INNER JOIN sys.columns sc ON so.OBJECT_ID = sc.OBJECT_ID AND sc.is_identity = 1 Let me know if you use any alternate method related to identity, I would like to know what you do and how you do when you have to deal with Identity Column.

XNA Seeing through heightmap problem

- by Jesse Emond

I've recently started learning how to program in 3D with XNA and I've been trying to implement a Terrain3D class(a very simple height map). I've managed to draw a simple terrain, but I'm getting a weird bug where I can see through the terrain. This bug happens when I'm looking through a hill from the map. Here is a picture of what happens: I was wondering if this is a common mistake for starters and if any of you ever experienced the same problem and could tell me what I'm doing wrong. If it's not such an obvious problem, here is my Draw method: public override void Draw() { Parent.Engine.SpriteBatch.Begin(SpriteBlendMode.None, SpriteSortMode.Immediate, SaveStateMode.SaveState); Camera3D cam = (Camera3D)Parent.Engine.Services.GetService(typeof(Camera3D)); if (cam == null) throw new Exception("Camera3D couldn't be found. Drawing a 3D terrain requires a 3D camera."); float triangleCount = indices.Length / 3f; basicEffect.Begin(); basicEffect.World = worldMatrix; basicEffect.View = cam.ViewMatrix; basicEffect.Projection = cam.ProjectionMatrix; basicEffect.VertexColorEnabled = true; Parent.Engine.GraphicsDevice.VertexDeclaration = new VertexDeclaration( Parent.Engine.GraphicsDevice, VertexPositionColor.VertexElements); foreach (EffectPass pass in basicEffect.CurrentTechnique.Passes) { pass.Begin(); Parent.Engine.GraphicsDevice.Vertices[0].SetSource(vertexBuffer, 0, VertexPositionColor.SizeInBytes); Parent.Engine.GraphicsDevice.Indices = indexBuffer; Parent.Engine.GraphicsDevice.DrawIndexedPrimitives(PrimitiveType.TriangleList, 0, 0, vertices.Length, 0, (int)triangleCount); pass.End(); } basicEffect.End(); Parent.Engine.SpriteBatch.End(); } Parent is just a property holding the screen that the component belongs to. Engine is a property of that parent screen holding the engine that it belongs to. If I should post more code(like the initialization code), then just leave a comment and I will.

Specify a custom dictionary for FxCop and Visual Studio source analysis

- by Marko Apfel

Renaming the default custom dictionary from CustomDictionary.xml to an other name – for instance FxCop.CustomDictionary.xml needs some additional changes to work in involved applications. Visual Studio Team System code analysis For Visual Studio Team System code analysis this file should be added as a link to all projects and setted to be the Build Action CodeAnalysisDirectory. Build target In a build target the command line tool FxCopCmd should be called with the /dictionary parameter: <Target Name="FxCop"> <Exec Command=""$(ProjectDir)..\..\build\FxCop\FxCopCmd.exe" /file:"$(TargetPath)" /project:"$(ProjectDir)..\EsriDE.SfgPraxair.FxCop" /directory:"$(ProjectDir)..\..\lib\Esri.ArcGIS" /directory:"$(ProjectDir)..\..\lib\Microsoft" /dictionary:"$(ProjectDir)..\FxCop.CustomDictionary.xml" /out:"$(OutDir)..\$(ProjectName).FxCopReport.xml" /console /forceoutput /ignoregeneratedcode"> </Exec> <Message Text="FxCop finished." /> </Target> FxCop-GUI (standalone application) In FxCop-GUI is no option to specify an own file name – but you could add a hint in the FxCop project file. Open your this file and look for the line: <CustomDictionaries SearchFxCopDir="True" SearchUserProfile="True" SearchProjectDir="True" /> Then change it to: <CustomDictionaries SearchFxCopDir="True" SearchUserProfile="True" SearchProjectDir="True"> <CustomDictionary Path="FxCop.CustomDictionary.xml"/> </CustomDictionaries> Ready :-)

I had Kubuntu 13.04 on my ThinkPad X220, and I upgraded to 13.10 and I am not able to connect to a wired or wireless connection. The new network tray icon does not show any entries at all. In the menu of the tray icon, there is an error saying: Require NetworkManager 0.9.8, found .

How to implement fast search on Azure Blob?

- by Vicky

I am done with writing the code to upload files (text files) to azure blob storage. Now I want to provide search based on text files content. For ex. If I search for "Hello" then the name of files that contains "Hello" words should appear in search result. Here my code to search class BlobSearch { static void Main(string[] args) { string searchText = "Hello"; CloudStorageAccount account = CloudStorageAccount.Parse(azureConString); CloudBlobClient blobClient = account.CreateCloudBlobClient(); CloudBlobContainer blobContainer = blobClient.GetContainerReference("MyBlobContainer"); blobContainer.FetchAttributes(); var blobItemList = blobContainer.ListBlobs(); foreach (var item in blobItemList) { string line = string.Empty; CloudBlockBlob blockBlob = blobContainer.GetBlockBlobReference(item.Uri.ToString()); if(blockBlob.Name.Contains(".txt")) { int lineno = 1; using (var stream = blockBlob.OpenRead()) { using (StreamReader reader = new StreamReader(stream)) { while ((line = reader.ReadLine()) != null) { if (line.IndexOf(searchText) != -1) { Console.WriteLine("Line : " + lineno +" => "+ blockBlob.Name); } lineno++; } } } } } Console.WriteLine("SEARCH COMPLETE"); Console.ReadLine(); } } Above code is working but it is too slow. Is there any way to do it faster or Can improve above code.

Domains with similar names and legal issues

- by abel

I recently purchased one of those domain names like del.icio.us. While registering I found that delicious.com was being used. Argument: I found that delicious.com belonged to the same category as my to-be website. It served premium delicious dishes. Counter Argument: My to-be domain though belonging to the same category, specialized in serving free but delicious dishes or in giving out links(affiliate) to other sites serving premium delicious dishes. Additional Counter Arguments: 1.delicious.com was not in English. 2.the del.icio.us in my domain name though having the same spelling, is not going to be used in the same fashion. For eg.(this may not make sense, because the names have been changed)the d in delicious on my website actually stands for the greek letter Delta(?/d) and since internationalized domains are still not easily typable, I am going for the english equivalent.The prefix holds importance for the theme of the service which my website intends to offer. My Question: Can I use the domain name del.icio.us for my website? How are these kinds of matters dealt? (The domain names used are fictitious. And I have already registered the domain but have not started using it.I chanced upon this domain name because it was short, easy to remember and suited the theme of my website.)

Explanation on how "Tell, Don't Ask" is considered good OO

- by Pubby

This blogpost was posted on Hacker News with several upvotes. Coming from C++, most of these examples seem to go against what I've been taught. Such as example #2: Bad: def check_for_overheating(system_monitor) if system_monitor.temperature > 100 system_monitor.sound_alarms end end versus good: system_monitor.check_for_overheating class SystemMonitor def check_for_overheating if temperature > 100 sound_alarms end end end The advice in C++ is that you should prefer free functions instead of member functions as they increase encapsulation. Both of these are identical semantically, so why prefer the choice that has access to more state? Example 4: Bad: def street_name(user) if user.address user.address.street_name else 'No street name on file' end end versus good: def street_name(user) user.address.street_name end class User def address @address || NullAddress.new end end class NullAddress def street_name 'No street name on file' end end Why is it the responsibility of User to format an unrelated error string? What if I want to do something besides print 'No street name on file' if it has no street? What if the street is named the same thing? Could someone enlighten me on the "Tell, Don't Ask" advantages and rationale? I am not looking for which is better, but instead trying to understand the author's viewpoint.

Google Blogger Website CName and/or Text File Issues

- by Francis Gibbons

I have a blogger Blog website and I would like to have it show up on my company website. I have read a couple articles out there on how to do it. A hand full of them talk about using FTP which is old and no longer available. However, I am trying to following along with this one: http://www.infinite42.com/small-business/integrate-blogger-blog-website Which seems pretty easy but I am having a problem getting Google to Verify the DNS CName or Text Record that I created on my Windows 2007 Server. Do I need to create this record at the registra level. Right now the domain is setup at the registra to point the www record to my server where on my server I tried the Txt Record and the CName Record with no luck in DNS. Here are the Google instructions for creating a CName file record in DNS: Follow the steps below to create a DNS (Domain Name System) record that proves to Google that you own the domain. Add the CNAME record below to the DNS configuration for abc.com. CNAME Label / Host: CNAME Destination / Target: Click Verify below. When Google finds this DNS record, we'll make you a verified owner of the domain. (Note: DNS changes may take some time. If we don't find the record immediately, we'll check for it periodically.) To stay verified, don't remove the DNS record, even after verification succeeds. Here is the link to do it with a CName: http://googlewebmastercentral.blogspot.com/2012/08/domain-verification-using-cname-records.html When I go to add my CName record on my server's DNS the only two fields available are Alias Name and Fully Qualified Domain Name. How am I suppose to create this record can someone please tell me? Thanks, Frank

Project Codenames - Yea or Nay?

- by rmx

Where I work, most of our projects have (or at least attempt) descriptive, useful names. However we have a few with names that make no sense: I found that an assembly named WiFi which actually has nothing whatsoever to do with wi-fi, but is a codename. When I asked why, I was told that it's to protect company secrets incase some intern has few too many at the pub on Friday and starts chatting about the brand new 'WiFi' project he's been working on. Its clear that some people find enjoyment in finding silly / amusing codenames for their projects (like in this question). My question is: is it really a good idea to use codenames for your projects or are you better off spending the time to decide upon a descriptive name? My opinion is that in the long-run its better to give your projects relevant names. My reasoning is that if you can't think of a decent name, perhaps you don't really know the requirements well enough. I think there are better ways to 'protect company secrets' and I find it quite confusing when the name does not correlate at all with the content. It's just common sense, surely?! So do you use codenames and what the your reasons for or against this seemingly common, yet annoying (to me at least) practice?

Semantic Form Markup for Yes or No Questions - Or Should I Tell my Designers to Bugger Off?

- by sholsinger

I frequently receive mock-ups of HTML forms with the following prototype: Some long winded yes or no question? (o) Yes ( ) No The (o) and ( ) in this prototype represent radio buttons. My personal view is that if the question has only a true or false value then it should be a check box. That said, I have seen this sort of "layout" from almost every designer I've ever worked with. If I were not to question their decision, or question the client's decision, I'd probably mark it up like this: <p class="pseudo_label">Some long winded yes or no question?</p> <input type="radio" name="the_question" id="the_question_yes" value="1"> <label for="the_question_yes" class="after_radio">Yes</label> <input type="radio" name="the_question" id="the_question_no" value="0"> <label for="the_question_no" class="after_radio">No</label> I really don't want to do that. I want to push back and convince them that this should really be a check box and not two radio buttons. But my question is, if I can't convince them – you're welcome to help me try – how should I code that original design requirement such that it is semantic and at least understandable for screen reader users? If I were able to convince my tormentors to change their minds, I would likely code it in the following fashion: <label for="the_question">Some long winded yes or no question?</label> <input type="checkbox" name="the_question" id="the_question" value="1"> What do you think about this issue? Should I push back? Possibly more importantly is either way semantically correct?
