How to ensure images all loaded before I reference in my HTML canvas [closed]

- by mark stephens

I want to draw some images in on a HTML canvas with context.drawImage(Im1 ,205,18,184,38); In order to make sure it loads I need to put in code like this but then I cannot draw things with it var Im1 = new Image(); Im1.src="rechnung11014page1/img/1/Im1.png"; Im1.onload = function() { context.drawImage(Im1 ,205,18,184,38); } Is there a way to load all the images and then execute a block of code using several images?

ASP.NET MVC: Using ProfileRequiredAttribute to restrict access to pages

- by DigiMortal

If you are using AppFabric Access Control Services to authenticate users when they log in to your community site using Live ID, Google or some other popular identity provider, you need more than AuthorizeAttribute to make sure that users can access the content that is there for authenticated users only. In this posting I will show you hot to extend the AuthorizeAttribute so users must also have user profile filled. Semi-authorized users When user is authenticated through external identity provider then not all identity providers give us user name or other information we ask users when they join with our site. What all identity providers have in common is unique ID that helps you identify the user. Example. Users authenticated through Windows Live ID by AppFabric ACS have no name specified. Google’s identity provider is able to provide you with user name and e-mail address if user agrees to publish this information to you. They both give you unique ID of user when user is successfully authenticated in their service. There is logical shift between ASP.NET and my site when considering user as authorized. For ASP.NET MVC user is authorized when user has identity. For my site user is authorized when user has profile and row in my users table. Having profile means that user has unique username in my system and he or she is always identified by this username by other users. My solution is simple: I created my own action filter attribute that makes sure if user has profile to access given method and if user has no profile then browser is redirected to join page. Illustrating the problem Usually we restrict access to page using AuthorizeAttribute. Code is something like this. [Authorize] public ActionResult Details(string id) { var profile = _userRepository.GetUserByUserName(id); return View(profile); } If this page is only for site users and we have user profiles then all users – the ones that have profile and all the others that are just authenticated – can access the information. It is okay because all these users have successfully logged in in some service that is supported by AppFabric ACS. In my site the users with no profile are in grey spot. They are on half way to be users because they have no username and profile on my site yet. So looking at the image above again we need something that adds profile existence condition to user-only content. [ProfileRequired] public ActionResult Details(string id) { var profile = _userRepository.GetUserByUserName(id); return View(profile); } Now, this attribute will solve our problem as soon as we implement it. ProfileRequiredAttribute: Profiles are required to be fully authorized Here is my implementation of ProfileRequiredAttribute. It is pretty new and right now it is more like working draft but you can already play with it. public class ProfileRequiredAttribute : AuthorizeAttribute { private readonly string _redirectUrl; public ProfileRequiredAttribute() { _redirectUrl = ConfigurationManager.AppSettings["JoinUrl"]; if (string.IsNullOrWhiteSpace(_redirectUrl)) _redirectUrl = "~/"; } public override void OnAuthorization(AuthorizationContext filterContext) { base.OnAuthorization(filterContext); var httpContext = filterContext.HttpContext; var identity = httpContext.User.Identity; if (!identity.IsAuthenticated || identity.GetProfile() == null) if(filterContext.Result == null) httpContext.Response.Redirect(_redirectUrl); } } All methods with this attribute work as follows: if user is not authenticated then he or she is redirected to AppFabric ACS identity provider selection page, if user is authenticated but has no profile then user is by default redirected to main page of site but if you have application setting with name JoinUrl then user is redirected to this URL. First case is handled by AuthorizeAttribute and the second one is handled by custom logic in ProfileRequiredAttribute class. GetProfile() extension method To get user profile using less code in places where profiles are needed I wrote GetProfile() extension method for IIdentity interface. There are some more extension methods that read out user and identity provider identifier from claims and based on this information user profile is read from database. If you take this code with copy and paste I am sure it doesn’t work for you but you get the idea. public static User GetProfile(this IIdentity identity) { if (identity == null) return null; var context = HttpContext.Current; if (context.Items["UserProfile"] != null) return context.Items["UserProfile"] as User; var provider = identity.GetIdentityProvider(); var nameId = identity.GetNameIdentifier(); var rep = ObjectFactory.GetInstance<IUserRepository>(); var profile = rep.GetUserByProviderAndNameId(provider, nameId); context.Items["UserProfile"] = profile; return profile; } To avoid round trips to database I cache user profile to current request because the chance that profile gets changed meanwhile is very minimal. The other reason is maybe more tricky – profile objects are coming from Entity Framework context and context has also HTTP request as lifecycle. Conclusion This posting gave you some ideas how to finish user profiles stuff when you use AppFabric ACS as external authentication provider. Although there was little shift between us and ASP.NET MVC with interpretation of “authorized” we were easily able to solve the problem by extending AuthorizeAttribute to get all our requirements fulfilled. We also write extension method for IIdentity that returns as user profile based on username and caches the profile in HTTP request scope.

SQL SERVER – SSIS Look Up Component – Cache Mode – Notes from the Field #028

- by Pinal Dave

[Notes from Pinal]: Lots of people think that SSIS is all about arranging various operations together in one logical flow. Well, the understanding is absolutely correct, but the implementation of the same is not as easy as it seems. Similarly most of the people think lookup component is just component which does look up for additional information and does not pay much attention to it. Due to the same reason they do not pay attention to the same and eventually get very bad performance. Linchpin People are database coaches and wellness experts for a data driven world. In this 28th episode of the Notes from the Fields series database expert Tim Mitchell (partner at Linchpin People) shares very interesting conversation related to how to write a good lookup component with Cache Mode. In SQL Server Integration Services, the lookup component is one of the most frequently used tools for data validation and completion. The lookup component is provided as a means to virtually join one set of data to another to validate and/or retrieve missing values. Properly configured, it is reliable and reasonably fast. Among the many settings available on the lookup component, one of the most critical is the cache mode. This selection will determine whether and how the distinct lookup values are cached during package execution. It is critical to know how cache modes affect the result of the lookup and the performance of the package, as choosing the wrong setting can lead to poorly performing packages, and in some cases, incorrect results. Full Cache The full cache mode setting is the default cache mode selection in the SSIS lookup transformation. Like the name implies, full cache mode will cause the lookup transformation to retrieve and store in SSIS cache the entire set of data from the specified lookup location. As a result, the data flow in which the lookup transformation resides will not start processing any data buffers until all of the rows from the lookup query have been cached in SSIS. The most commonly used cache mode is the full cache setting, and for good reason. The full cache setting has the most practical applications, and should be considered the go-to cache setting when dealing with an untested set of data. With a moderately sized set of reference data, a lookup transformation using full cache mode usually performs well. Full cache mode does not require multiple round trips to the database, since the entire reference result set is cached prior to data flow execution. There are a few potential gotchas to be aware of when using full cache mode. First, you can see some performance issues – memory pressure in particular – when using full cache mode against large sets of reference data. If the table you use for the lookup is very large (either deep or wide, or perhaps both), there’s going to be a performance cost associated with retrieving and caching all of that data. Also, keep in mind that when doing a lookup on character data, full cache mode will always do a case-sensitive (and in some cases, space-sensitive) string comparison even if your database is set to a case-insensitive collation. This is because the in-memory lookup uses a .NET string comparison (which is case- and space-sensitive) as opposed to a database string comparison (which may be case sensitive, depending on collation). There’s a relatively easy workaround in which you can use the UPPER() or LOWER() function in the pipeline data and the reference data to ensure that case differences do not impact the success of your lookup operation. Again, neither of these present a reason to avoid full cache mode, but should be used to determine whether full cache mode should be used in a given situation. Full cache mode is ideally useful when one or all of the following conditions exist: The size of the reference data set is small to moderately sized The size of the pipeline data set (the data you are comparing to the lookup table) is large, is unknown at design time, or is unpredictable Each distinct key value(s) in the pipeline data set is expected to be found multiple times in that set of data Partial Cache When using the partial cache setting, lookup values will still be cached, but only as each distinct value is encountered in the data flow. Initially, each distinct value will be retrieved individually from the specified source, and then cached. To be clear, this is a row-by-row lookup for each distinct key value(s). This is a less frequently used cache setting because it addresses a narrower set of scenarios. Because each distinct key value(s) combination requires a relational round trip to the lookup source, performance can be an issue, especially with a large pipeline data set to be compared to the lookup data set. If you have, for example, a million records from your pipeline data source, you have the potential for doing a million lookup queries against your lookup data source (depending on the number of distinct values in the key column(s)). Therefore, one has to be keenly aware of the expected row count and value distribution of the pipeline data to safely use partial cache mode. Using partial cache mode is ideally suited for the conditions below: The size of the data in the pipeline (more specifically, the number of distinct key column) is relatively small The size of the lookup data is too large to effectively store in cache The lookup source is well indexed to allow for fast retrieval of row-by-row values No Cache As you might guess, selecting no cache mode will not add any values to the lookup cache in SSIS. As a result, every single row in the pipeline data set will require a query against the lookup source. Since no data is cached, it is possible to save a small amount of overhead in SSIS memory in cases where key values are not reused. In the real world, I don’t see a lot of use of the no cache setting, but I can imagine some edge cases where it might be useful. As such, it’s critical to know your data before choosing this option. Obviously, performance will be an issue with anything other than small sets of data, as the no cache setting requires row-by-row processing of all of the data in the pipeline. I would recommend considering the no cache mode only when all of the below conditions are true: The reference data set is too large to reasonably be loaded into SSIS memory The pipeline data set is small and is not expected to grow There are expected to be very few or no duplicates of the key values(s) in the pipeline data set (i.e., there would be no benefit from caching these values) Conclusion The cache mode, an often-overlooked setting on the SSIS lookup component, represents an important design decision in your SSIS data flow. Choosing the right lookup cache mode directly impacts the fidelity of your results and the performance of package execution. Know how this selection impacts your ETL loads, and you’ll end up with more reliable, faster packages. If you want me to take a look at your server and its settings, or if your server is facing any issue we can Fix Your SQL Server.

Full-text Indexing Books Online

- by Most Valuable Yak (Rob Volk)

While preparing for a recent SQL Saturday presentation, I was struck by a crazy idea (shocking, I know): Could someone import the content of SQL Server Books Online into a database and apply full-text indexing to it? The answer is yes, and it's really quite easy to do. The first step is finding the installed help files. If you have SQL Server 2012, BOL is installed under the Microsoft Help Library. You can find the install location by opening SQL Server Books Online and clicking the gear icon for the Help Library Manager. When the new window pops up click the Settings link, you'll get the following: You'll see the path under Library Location. Once you navigate to that path you'll have to drill down a little further, to C:\ProgramData\Microsoft\HelpLibrary\content\Microsoft\store. This is where the help file content is kept if you downloaded it for offline use. Depending on which products you've downloaded help for, you may see a few hundred files. Fortunately they're named well and you can easily find the "SQL_Server_Denali_Books_Online_" files. We are interested in the .MSHC files only, and can skip the Installation and Developer Reference files. Despite the .MHSC extension, these files are compressed with the standard Zip format, so your favorite archive utility (WinZip, 7Zip, WinRar, etc.) can open them. When you do, you'll see a few thousand files in the archive. We are only interested in the .htm files, but there's no harm in extracting all of them to a folder. 7zip provides a command-line utility and the following will extract to a D:\SQLHelp folder previously created: 7z e –oD:\SQLHelp "C:\ProgramData\Microsoft\HelpLibrary\content\Microsoft\store\SQL_Server_Denali_Books_Online_B780_SQL_110_en-us_1.2.mshc" *.htm Well that's great Rob, but how do I put all those files into a full-text index? I'll tell you in a second, but first we have to set up a few things on the database side. I'll be using a database named Explore (you can certainly change that) and the following setup is a fragment of the script I used in my presentation: USE Explore; GO CREATE SCHEMA help AUTHORIZATION dbo; GO -- Create default fulltext catalog for later FT indexes CREATE FULLTEXT CATALOG FTC AS DEFAULT; GO CREATE TABLE help.files(file_id int not null IDENTITY(1,1) CONSTRAINT PK_help_files PRIMARY KEY, path varchar(256) not null CONSTRAINT UNQ_help_files_path UNIQUE, doc_type varchar(6) DEFAULT('.xml'), content varbinary(max) not null); CREATE FULLTEXT INDEX ON help.files(content TYPE COLUMN doc_type LANGUAGE 1033) KEY INDEX PK_help_files; This will give you a table, default full-text catalog, and full-text index on that table for the content you're going to insert. I'll be using the command line again for this, it's the easiest method I know: for %a in (D:\SQLHelp\*.htm) do sqlcmd -S. -E -d Explore -Q"set nocount on;insert help.files(path,content) select '%a', cast(c as varbinary(max)) from openrowset(bulk '%a', SINGLE_CLOB) as c(c)" You'll need to copy and run that as one line in a command prompt. I'll explain what this does while you run it and watch several thousand files get imported: The "for" command allows you to loop over a collection of items. In this case we want all the .htm files in the D:\SQLHelp folder. For each file it finds, it will assign the full path and file name to the %a variable. In the "do" clause, we'll specify another command to be run for each iteration of the loop. I make a call to "sqlcmd" in order to run a SQL statement. I pass in the name of the server (-S.), where "." represents the local default instance. I specify -d Explore as the database, and -E for trusted connection. I then use -Q to run a query that I enclose in double quotes. The query uses OPENROWSET(BULK…SINGLE_CLOB) to open the file as a data source, and to treat it as a single character large object. In order for full-text indexing to work properly, I have to convert the text content to varbinary. I then INSERT these contents along with the full path of the file into the help.files table created earlier. This process continues for each file in the folder, creating one new row in the table. And that's it! 5 SQL Statements and 2 command line statements to unzip and import SQL Server Books Online! In case you're wondering why I didn't use FILESTREAM or FILETABLE, it's simply because I haven't learned them…yet. I may return to this blog after I figure that out and update it with the steps to do so. I believe that will make it even easier. In the spirit of exploration, I'll leave you to work on some fulltext queries of this content. I also recommend playing around with the sys.dm_fts_xxxx DMVs (I particularly like sys.dm_fts_index_keywords, it's pretty interesting). There are additional example queries in the download material for my presentation linked above. Many thanks to Kevin Boles (t) for his advice on (re)checking the content of the help files. Don't let that .htm extension fool you! The 2012 help files are actually XML, and you'd need to specify '.xml' in your document type column in order to extract the full-text keywords. (You probably noticed this in the default definition for the doc_type column.) You can query sys.fulltext_document_types to get a complete list of the types that can be full-text indexed. I also need to thank Hilary Cotter for giving me the original idea. I believe he used MSDN content in a full-text index for an article from waaaaaaaaaaay back, that I can't find now, and had forgotten about until just a few days ago. He is also co-author of Pro Full-Text Search in SQL Server 2008, which I highly recommend. He also has some FTS articles on Simple Talk: http://www.simple-talk.com/sql/learn-sql-server/sql-server-full-text-search-language-features/ http://www.simple-talk.com/sql/learn-sql-server/sql-server-full-text-search-language-features,-part-2/

The challenge of communicating externally with IRM secured content

- by Simon Thorpe

I am often asked by customers about how they handle sending IRM secured documents to external parties. Their concern is that using IRM to secure sensitive information they need to share outside their business, is troubled with the inability for third parties to install the software which enables them to gain access to the information. It is a very legitimate question and one i've had to answer many times in the past 10 years whilst helping customers plan successful IRM deployments. The operating system does not provide the required level of content security The problem arises from what IRM delivers, persistent security to your sensitive information where ever it resides and whenever it is in use. Oracle IRM gives customers an array of features that help ensure sensitive information in an IRM document or email is always protected and only accessed by authorized users using legitimate applications. Examples of such functionality are; Control of the clipboard, either by disabling completely in the opened document or by allowing the cut and pasting of information between secured IRM documents but not into insecure applications. Protection against programmatic access to the document. Office documents and PDF documents have the ability to be accessed by other applications and scripts. With Oracle IRM we have to protect against this to ensure content cannot be leaked by someone writing a simple program. Securing of decrypted content in memory. At some point during the process of opening and presenting a sealed document to an end user, we must decrypt it and give it to the application (Adobe Reader, Microsoft Word, Excel etc). This process must be secure so that someone cannot simply get access to the decrypted information. The operating system alone just doesn't have the functionality to deliver these types of features. This is why for every IRM technology there must be some extra software installed and typically this software requires administrative rights to do so. The fact is that if you want to have very strong security and access control over a document you are going to send to someone who is beyond your network infrastructure, there must be some software to provide that functionality. Simple installation with Oracle IRM The software used to control access to Oracle IRM sealed content is called the Oracle IRM Desktop. It is a small, free piece of software roughly about 12mb in size. This software delivers functionality for everything a user needs to work with an Oracle IRM solution. It provides the functionality for all formats we support, the storage and transparent synchronization of user rights and unique to Oracle, the ability to search inside sealed files stored on the local computer. In Oracle we've made every technical effort to ensure that installing this software is a simple as possible. In situations where the user's computer is part of the enterprise, this software is typically deployed using existing technologies such as Systems Management Server from Microsoft or by using Active Directory Group Policies. However when sending sealed content externally, you cannot automatically install software on the end users machine. You need to rely on them to download and install themselves. Again we've made every effort for this manual install process to be as simple as we can. Starting with the small download size of the software itself to the simple installation process, most end users are able to install and access sealed content very quickly. You can see for yourself how easily this is done by walking through our free and easy self service demonstration of using sealed content. How to handle objections and ensure there is value However the fact still remains that end users may object to installing, or may simply be unable to install the software themselves due to lack of permissions. This is often a problem with any technology that requires specialized software to access a new type of document. In Oracle, over the past 10 years, we've learned many ways to get over this barrier of getting software deployed by external users. First and I would say of most importance, is the content MUST have some value to the person you are asking to install software. Without some type of value proposition you are going to find it very difficult to get past objections to installing the IRM Desktop. Imagine if you were going to secure the weekly campus restaurant menu and send this to contractors. Their initial response will be, "why on earth are you asking me to download some software just to access your menu!?". A valid objection... there is no value to the user in doing this. Now consider the scenario where you are sending one of your contractors their employment contract which contains their address, social security number and bank account details. Are they likely to take 5 minutes to install the IRM Desktop? You bet they are, because there is real value in doing so and they understand why you are doing it. They want their personal information to be securely handled and a quick download and install of some software is a small task in comparison to dealing with the loss of this information. Be clear in communicating this value So when sending sealed content to people externally, you must be clear in communicating why you are using an IRM technology and why they need to install some software to access the content. Do not try and avoid the issue, you must be clear and upfront about it. In doing so you will significantly reduce the "I didn't know I needed to do this..." responses and also gain respect for being straight forward. One customer I worked with, 6 months after the initial deployment of Oracle IRM, called me panicking that the partner they had started to share their engineering documents with refused to install any software to access this highly confidential intellectual property. I explained they had to communicate to the partner why they were doing this. I told them to go back with the statement that "the company takes protecting its intellectual property seriously and had decided to use IRM to control access to engineering documents." and if the partner didn't respect this decision, they would find another company that would. The result? A few days later the partner had made the Oracle IRM Desktop part of their approved list of software in the company. Companies are successful when sending sealed content to third parties We have many, many customers who send sensitive content to third parties. Some customers actually sell access to Oracle IRM protected content and therefore 99% of their users are external to their business, one in particular has sold content to hundreds of thousands of external users. Oracle themselves use the technology to secure M&A documents, payroll data and security assessments which go beyond the traditional enterprise security perimeter. Pretty much every company who deploys Oracle IRM will at some point be sending those documents to people outside of the company, these customers must be successful otherwise Oracle IRM wouldn't be successful. Because our software is used by a wide variety of companies, some who use it to sell content, i've often run into people i'm sharing a sealed document with and they already have the IRM Desktop installed due to accessing content from another company. The future In summary I would say that yes, this is a hurdle that many customers are concerned about but we see much evidence that in practice, people leap that hurdle with relative ease as long as they are good at communicating the value of using IRM and also take measures to ensure end users can easily go through the process of installation. We are constantly developing new ideas to reducing this hurdle and maybe one day the operating systems will give us enough rich security functionality to have no software installation. Until then, Oracle IRM is by far the easiest solution to balance security and usability for your business. If you would like to evaluate it for yourselves, please contact us.

How to create Custom ListForm WebPart

- by DipeshBhanani

Mostly all who works extensively on SharePoint (including meJ) don’t like to use out-of-box list forms (DispForm.aspx, EditForm.aspx, NewForm.aspx) as interface. Actually these OOB list forms bind hands of developers for the customization. It gives headache to developers to add just one post back event, for a dropdown field and to populate other fields in NewForm.aspx or EditForm.aspx. On top of that clients always ask such stuff. So here I am going to give you guys a flight for SharePoint Customization world. In this blog, I will explain, how to create CustomListForm WebPart. In my next blogs, I am going to explain easy deployment of List Forms through features and last, guidance on using SharePoint web controls. 1. First thing, create a class library project through Visual Studio and inherit the class with WebPart class. public class CustomListForm : WebPart 2. Declare the public variables and properties which we are going to use throughout the class. You will get to know these once you see them in use. #region "Variable Declaration" Table spTableCntl; FormToolBar formToolBar; Literal ltAlertMessage; Guid SiteId; Guid ListId; int ItemId; string ListName; #endregion #region "Properties" SPControlMode _ControlMode = SPControlMode.New; [Personalizable(PersonalizationScope.Shared), WebBrowsable(true), WebDisplayName("Control Mode"), WebDescription("Set Control Mode"), DefaultValue(""), Category("Miscellaneous")] public SPControlMode ControlMode { get { return _ControlMode; } set { _ControlMode = value; } } #endregion The property “ControlMode” is used to identify the mode of the List Form. The property is of type SPControlMode which is an enum type with values (Display, Edit, New and Invalid). When we will add this WebPart to DispForm.aspx, EditForm.aspx and NewForm.aspx, we will set the WebPart property “ControlMode” to Display, Edit and New respectively. 3. Now, we need to override the CreateChildControl method and write code to manually add SharePoint Web Controls related to each list fields as well as ToolBar controls. protected override void CreateChildControls() { base.CreateChildControls(); try { SiteId = SPContext.Current.Site.ID; ListId = SPContext.Current.ListId; ListName = SPContext.Current.List.Title; if (_ControlMode == SPControlMode.Display || _ControlMode == SPControlMode.Edit) ItemId = SPContext.Current.ItemId; SPSecurity.RunWithElevatedPrivileges(delegate() { using (SPSite site = new SPSite(SiteId)) { //creating a new SPSite with credentials of System Account using (SPWeb web = site.OpenWeb()) { //<Custom Code for creating form controls> } } }); } catch (Exception ex) { ShowError(ex, "CreateChildControls"); } } Here we are assuming that we are developing this WebPart to plug into List Forms. Hence we will get the List Id and List Name from the current context. We can have Item Id only in case of Display and Edit Mode. We are putting our code into “RunWithElevatedPrivileges” to elevate privileges to System Account. Now, let’s get deep down into the main code and expand “//<Custom Code for creating form controls>”. Before initiating any SharePoint control, we need to set context of SharePoint web controls explicitly so that it will be instantiated with elevated System Account user. Following line does the job. //To create SharePoint controls with new web object and System Account credentials SPControl.SetContextWeb(Context, web); First thing, let’s add main table as container for all controls. //Table to render webpart Table spTableMain = new Table(); spTableMain.CellPadding = 0; spTableMain.CellSpacing = 0; spTableMain.Width = new Unit(100, UnitType.Percentage); this.Controls.Add(spTableMain); Now we need to add Top toolbar with Save and Cancel button at top as you see in the below screen shot. // Add Row and Cell for Top ToolBar TableRow spRowTopToolBar = new TableRow(); spTableMain.Rows.Add(spRowTopToolBar); TableCell spCellTopToolBar = new TableCell(); spRowTopToolBar.Cells.Add(spCellTopToolBar); spCellTopToolBar.Width = new Unit(100, UnitType.Percentage); ToolBar toolBarTop = (ToolBar)Page.LoadControl("/_controltemplates/ToolBar.ascx"); toolBarTop.CssClass = "ms-formtoolbar"; toolBarTop.ID = "toolBarTbltop"; toolBarTop.RightButtons.SeparatorHtml = "<td class=ms-separator> </td>"; if (_ControlMode != SPControlMode.Display) { SaveButton btnSave = new SaveButton(); btnSave.ControlMode = _ControlMode; btnSave.ListId = ListId; if (_ControlMode == SPControlMode.New) btnSave.RenderContext = SPContext.GetContext(web); else { btnSave.RenderContext = SPContext.GetContext(this.Context, ItemId, ListId, web); btnSave.ItemContext = SPContext.GetContext(this.Context, ItemId, ListId, web); btnSave.ItemId = ItemId; } toolBarTop.RightButtons.Controls.Add(btnSave); } GoBackButton goBackButtonTop = new GoBackButton(); toolBarTop.RightButtons.Controls.Add(goBackButtonTop); goBackButtonTop.ControlMode = SPControlMode.Display; spCellTopToolBar.Controls.Add(toolBarTop); Here we have use “SaveButton” and “GoBackButton” which are internal SharePoint web controls for save and cancel functionality. I have set some of the properties of Save Button with if-else condition because we will not have Item Id in case of New Mode. Item Id property is used to identify which SharePoint List Item need to be saved. Now, add Form Toolbar to the page which contains “Attach File”, “Delete Item” etc buttons. // Add Row and Cell for FormToolBar TableRow spRowFormToolBar = new TableRow(); spTableMain.Rows.Add(spRowFormToolBar); TableCell spCellFormToolBar = new TableCell(); spRowFormToolBar.Cells.Add(spCellFormToolBar); spCellFormToolBar.Width = new Unit(100, UnitType.Percentage); FormToolBar formToolBar = new FormToolBar(); formToolBar.ID = "formToolBar"; formToolBar.ListId = ListId; if (_ControlMode == SPControlMode.New) formToolBar.RenderContext = SPContext.GetContext(web); else { formToolBar.RenderContext = SPContext.GetContext(this.Context, ItemId, ListId, web); formToolBar.ItemContext = SPContext.GetContext(this.Context, ItemId, ListId, web); formToolBar.ItemId = ItemId; } formToolBar.ControlMode = _ControlMode; formToolBar.EnableViewState = true; spCellFormToolBar.Controls.Add(formToolBar); The ControlMode property will take care of which button to be displayed on the toolbar. E.g. “Attach files”, “Delete Item” in new/edit forms and “New Item”, “Edit Item”, “Delete Item”, “Manage Permissions” etc in display forms. Now add main section which contains form field controls. //Create Form Field controls and add them in Table "spCellCntl" CreateFieldControls(web); //Add public variable "spCellCntl" containing all form controls to the page spRowCntl.Cells.Add(spCellCntl); spCellCntl.Width = new Unit(100, UnitType.Percentage); spCellCntl.Controls.Add(spTableCntl); //Add a Blank Row with height of 5px to render space between ToolBar table and Control table TableRow spRowLine1 = new TableRow(); spTableMain.Rows.Add(spRowLine1); TableCell spCellLine1 = new TableCell(); spRowLine1.Cells.Add(spCellLine1); spCellLine1.Height = new Unit(5, UnitType.Pixel); spCellLine1.Controls.Add(new LiteralControl("<IMG SRC='/_layouts/images/blank.gif' width=1 height=1 alt=''>")); //Add Row and Cell for Form Controls Section TableRow spRowCntl = new TableRow(); spTableMain.Rows.Add(spRowCntl); TableCell spCellCntl = new TableCell(); //Create Form Field controls and add them in Table "spCellCntl" CreateFieldControls(web); //Add public variable "spCellCntl" containing all form controls to the page spRowCntl.Cells.Add(spCellCntl); spCellCntl.Width = new Unit(100, UnitType.Percentage); spCellCntl.Controls.Add(spTableCntl); TableRow spRowLine2 = new TableRow(); spTableMain.Rows.Add(spRowLine2); TableCell spCellLine2 = new TableCell(); spRowLine2.Cells.Add(spCellLine2); spCellLine2.CssClass = "ms-formline"; spCellLine2.Controls.Add(new LiteralControl("<IMG SRC='/_layouts/images/blank.gif' width=1 height=1 alt=''>")); // Add Blank row with height of 5 pixel TableRow spRowLine3 = new TableRow(); spTableMain.Rows.Add(spRowLine3); TableCell spCellLine3 = new TableCell(); spRowLine3.Cells.Add(spCellLine3); spCellLine3.Height = new Unit(5, UnitType.Pixel); spCellLine3.Controls.Add(new LiteralControl("<IMG SRC='/_layouts/images/blank.gif' width=1 height=1 alt=''>")); You can add bottom toolbar also to get same look and feel as OOB forms. I am not adding here as the blog will be much lengthy. At last, you need to write following lines to allow unsafe updates for Save and Delete button. // Allow unsafe update on web for save button and delete button if (this.Page.IsPostBack && this.Page.Request["__EventTarget"] != null && (this.Page.Request["__EventTarget"].Contains("IOSaveItem") || this.Page.Request["__EventTarget"].Contains("IODeleteItem"))) { SPContext.Current.Web.AllowUnsafeUpdates = true; } So that’s all. We have finished writing Custom Code for adding field control. But something most important is skipped. In above code, I have called function “CreateFieldControls(web);” to add SharePoint field controls to the page. Let’s see the implementation of the function: private void CreateFieldControls(SPWeb pWeb) { SPList listMain = pWeb.Lists[ListId]; SPFieldCollection fields = listMain.Fields; //Main Table to render all fields spTableCntl = new Table(); spTableCntl.BorderWidth = new Unit(0); spTableCntl.CellPadding = 0; spTableCntl.CellSpacing = 0; spTableCntl.Width = new Unit(100, UnitType.Percentage); spTableCntl.CssClass = "ms-formtable"; SPContext controlContext = SPContext.GetContext(this.Context, ItemId, ListId, pWeb); foreach (SPField listField in fields) { string fieldDisplayName = listField.Title; string fieldInternalName = listField.InternalName; //Skip if the field is system field or hidden if (listField.Hidden || listField.ShowInVersionHistory == false) continue; //Skip if the control mode is display and field is read-only if (_ControlMode != SPControlMode.Display && listField.ReadOnlyField == true) continue; FieldLabel fieldLabel = new FieldLabel(); fieldLabel.FieldName = listField.InternalName; fieldLabel.ListId = ListId; BaseFieldControl fieldControl = listField.FieldRenderingControl; fieldControl.ListId = ListId; //Assign unique id using Field Internal Name fieldControl.ID = string.Format("Field_{0}", fieldInternalName); fieldControl.EnableViewState = true; //Assign control mode fieldLabel.ControlMode = _ControlMode; fieldControl.ControlMode = _ControlMode; switch (_ControlMode) { case SPControlMode.New: fieldLabel.RenderContext = SPContext.GetContext(pWeb); fieldControl.RenderContext = SPContext.GetContext(pWeb); break; case SPControlMode.Edit: case SPControlMode.Display: fieldLabel.RenderContext = controlContext; fieldLabel.ItemContext = controlContext; fieldLabel.ItemId = ItemId; fieldControl.RenderContext = controlContext; fieldControl.ItemContext = controlContext; fieldControl.ItemId = ItemId; break; } //Add row to display a field row TableRow spCntlRow = new TableRow(); spTableCntl.Rows.Add(spCntlRow); //Add the cells for containing field lable and control TableCell spCellLabel = new TableCell(); spCellLabel.Width = new Unit(30, UnitType.Percentage); spCellLabel.CssClass = "ms-formlabel"; spCntlRow.Cells.Add(spCellLabel); TableCell spCellControl = new TableCell(); spCellControl.Width = new Unit(70, UnitType.Percentage); spCellControl.CssClass = "ms-formbody"; spCntlRow.Cells.Add(spCellControl); //Add the control to the table cells spCellLabel.Controls.Add(fieldLabel); spCellControl.Controls.Add(fieldControl); //Add description if there is any in case of New and Edit Mode if (_ControlMode != SPControlMode.Display && listField.Description != string.Empty) { FieldDescription fieldDesc = new FieldDescription(); fieldDesc.FieldName = fieldInternalName; fieldDesc.ListId = ListId; spCellControl.Controls.Add(fieldDesc); } //Disable Name(Title) in Edit Mode if (_ControlMode == SPControlMode.Edit && fieldDisplayName == "Name") { TextBox txtTitlefield = (TextBox)fieldControl.Controls[0].FindControl("TextField"); txtTitlefield.Enabled = false; } } fields = null; } First of all, I have declared List object and got list fields in field collection object called “fields”. Then I have added a table for the container of all controls and assign CSS class as "ms-formtable" so that it gives consistent look and feel of SharePoint. Now it’s time to navigate through all fields and add them if required. Here we don’t need to add hidden or system fields. We also don’t want to display read-only fields in new and edit forms. Following lines does this job. //Skip if the field is system field or hidden if (listField.Hidden || listField.ShowInVersionHistory == false) continue; //Skip if the control mode is display and field is read-only if (_ControlMode != SPControlMode.Display && listField.ReadOnlyField == true) continue; Let’s move to the next line of code. FieldLabel fieldLabel = new FieldLabel(); fieldLabel.FieldName = listField.InternalName; fieldLabel.ListId = ListId; BaseFieldControl fieldControl = listField.FieldRenderingControl; fieldControl.ListId = ListId; //Assign unique id using Field Internal Name fieldControl.ID = string.Format("Field_{0}", fieldInternalName); fieldControl.EnableViewState = true; //Assign control mode fieldLabel.ControlMode = _ControlMode; fieldControl.ControlMode = _ControlMode; We have used “FieldLabel” control for displaying field title. The advantage of using Field Label is, SharePoint automatically adds red star besides field label to identify it as mandatory field if there is any. Here is most important part to understand. The “BaseFieldControl”. It will render the respective web controls according to type of the field. For example, if it’s single line of text, then Textbox, if it’s look up then it renders dropdown. Additionally, the “ControlMode” property tells compiler that which mode (display/edit/new) controls need to be rendered with. In display mode, it will render label with field value. In edit mode, it will render respective control with item value and in new mode it will render respective control with empty value. Please note that, it’s not always the case when dropdown field will be rendered for Lookup field or Choice field. You need to understand which controls are rendered for which list fields. I am planning to write a separate blog which I hope to publish it very soon. Moreover, we also need to assign list field specific properties like List Id, Field Name etc to identify which SharePoint List field is attached with the control. switch (_ControlMode) { case SPControlMode.New: fieldLabel.RenderContext = SPContext.GetContext(pWeb); fieldControl.RenderContext = SPContext.GetContext(pWeb); break; case SPControlMode.Edit: case SPControlMode.Display: fieldLabel.RenderContext = controlContext; fieldLabel.ItemContext = controlContext; fieldLabel.ItemId = ItemId; fieldControl.RenderContext = controlContext; fieldControl.ItemContext = controlContext; fieldControl.ItemId = ItemId; break; } Here, I have separate code for new mode and Edit/Display mode because we will not have Item Id to assign in New Mode. We also need to set CSS class for cell containing Label and Controls so that those controls get rendered with SharePoint theme. spCellLabel.CssClass = "ms-formlabel"; spCellControl.CssClass = "ms-formbody"; “FieldDescription” control is used to add field description if there is any. Now it’s time to add some more customization, //Disable Name(Title) in Edit Mode if (_ControlMode == SPControlMode.Edit && fieldDisplayName == "Name") { TextBox txtTitlefield = (TextBox)fieldControl.Controls[0].FindControl("TextField"); txtTitlefield.Enabled = false; } The above code will disable the title field in edit mode. You can add more code here to achieve more customization according to your requirement. Some of the examples are as follow: //Adding post back event on UserField to auto populate some other dependent field //in new mode and disable it in edit mode if (_ControlMode != SPControlMode.Display && fieldDisplayName == "Manager") { if (fieldControl.Controls[0].FindControl("UserField") != null) { PeopleEditor pplEditor = (PeopleEditor)fieldControl.Controls[0].FindControl("UserField"); if (_ControlMode == SPControlMode.New) pplEditor.AutoPostBack = true; else pplEditor.Enabled = false; } } //Add JavaScript Event on Dropdown field. Don't forget to add the JavaScript function on the page. if (_ControlMode == SPControlMode.Edit && fieldDisplayName == "Designation") { DropDownList ddlCategory = (DropDownList)fieldControl.Controls[0]; ddlCategory.Attributes.Add("onchange", string.Format("javascript:DropdownChangeEvent('{0}');return false;", ddlCategory.ClientID)); } Following are the screenshots of my Custom ListForm WebPart. Let’s play a game, check out your OOB List forms of SharePoint, compare with these screens and find out differences. DispForm.aspx: EditForm.aspx: NewForm.aspx: Enjoy the SharePoint Soup!!!

BizTalk Send Ports, Delivery Notification and ACK / NACK messages

- by Robert Kokuti

Recently I worked on an orchestration which sent messages out to a Send Port on a 'fire and forget' basis. The idea was that once the orchestration passed the message to the Messagebox, it was left to BizTalk to manage the sending process. Should the send operation fail, the Send Port got suspended, and the orchestration completed asynchronously, regardless of the Send Port success or failure. However, we still wanted to log the sending success, using the ACK / NACK messages. On normal ports, BizTalk generates ACK / NACK messages back to the Messagebox, if the logical port's Delivery Notification property is set to 'Transmitted'. Unfortunately, this setting also causes the orchestration to wait for the send port's result, and should the Send Port fail, the orchestration will also receive a 'DeliveryFailureException' exception. So we may end up with a suspended port and a suspended orchestration - not the outcome wanted here, there was no value in suspending the orchestration in our case. There are a couple of ways to fix this: 1. Catch the DeliveryFailureException (full type name Microsoft.XLANGs.BaseTypes.DeliveryFailureException) and do nothing in the orchestration's exception block. Although this works, it still slows down the orchestration as the orchestration still has to wait for the outcome of the send port operation. 2. Use a Direct Port instead, and set the ACK request on the message Context, prior passing to the port: msgToSend(BTS.AckRequired) = true; This has to be done in an expression shape, as a Direct logical port does not have Delivery Notification property - make sure to add a reference to Microsoft.BizTalk.GlobalPropertySchemas. Setting this context value in the message will cause the messaging agent to create an appropriate ACK or NACK message after the port execution. The ACK / NACK messages can be caught and logged by dedicated Send Ports, filtering on BTS.AckType value (which is either ACK or NACK). ACK/NACK messages are treated in a special way by BizTalk, and a useful feature is that the original message's context values are copied to the ACK/NACK message context - these can be used for logging the right information. Other useful context properties of the ACK/NACK messages: - BTS.AckSendPortName can be used to identify the original send port. - BTS.AckOwnerID, aka http://schemas.microsoft.com/BizTalk/2003/system-properties.AckOwnerID - holds the instance ID of the failed Send Port - can be used to resubmit / terminate the instance Someone may ask, can we just turn off the Delivery Notification on a 'normal' port, and set the AckRequired property on the message as for a Direct port. Unfortunately, this does not work - BizTalk seems to remove this property automatically, if the message goes through a port where Delivery Notification is set to None.

Creating classed in JavaScript

- by Renso

Goal:Creating class instances in JavaScript is not available since you define "classes" in js with object literals. In order to create classical classes like you would in c#, ruby, java, etc, with inheritance and instances.Rather than typical class definitions using object literals, js has a constructor function and the NEW operator that will allow you to new-up a class and optionally provide initial properties to initialize the new object with.The new operator changes the function's context and behavior of the return statement.var Person = function(name) { this.name = name;}; //Init the personvar dude= new Person("renso");//Validate the instanceassert(dude instanceof Person);When a constructor function is called with the new keyword, the context changes from global window to a new and empty context specific to the instance; "this" will refer in this case to the "dude" context.Here is class pattern that you will need to define your own CLASS emulation library:var Class = function() { var _class = function() { this.init.apply(this, arguments); }; _class.prototype.init = function(){}; return _class;}var Person a new Class();Person.prototype.init = function() {};var person = new Person;In order for the class emulator to support adding functions and properties to static classes as well as object instances of People, change the emulator:var Class = function() { var _class = function() { this.init.apply(this, arguments); }; _class.prototype.init = function(){}; _class.fn = _class.prototype; _class.fn.parent = _class; //adding class properties _class.extend = function(obj) { var extended = obj.extended; for(var i in obj) { _class[i] = obj[i]; }; if(extended) extended(_class); }; //adding new instances _class.include = function(obj) { var included = obj.included; for(var i in obj) { _class.fn[i] = obj[i]; }; if(included) included(_class); }; return _class;}Now you can use it to create and extend your own object instances://adding static functions to the class Personvar Person = new Class();Person.extend({ find: function(name) {/*....*/}, delete: function(id) {/*....*/},});//calling static function findvar person = Person.find('renso'); //adding properties and functions to the class' prototype so that they are available on instances of the class Personvar Person = new Class;Person.extend({ save: function(name) {/*....*/}, delete: function(id) {/*....*/}});var dude = new Person;//calling instance functiondude.save('renso');

P.S. I'm not familiar with shaders yet, so it is difficult for me to make use of them right now.

Issue 15: SVP Focus

- by rituchhibber

SVP FOCUS FOCUS -- Chris Baker SVP Oracle Worldwide ISV-OEM-Java Sales Chris Baker is the Global Head of ISV/OEM Sales responsible for working with ISV/OEM partners to maximise Oracle's business through those partners, whilst maximising those partners’ business to their end users. Chris works with partners, customers, innovators, investors and employees to develop innovative business solutions using Oracle products, services and skills. RESOURCES -- Oracle PartnerNetwork (OPN) OPN Solutions Catalog Oracle Exastack Program Oracle Exastack Optimized Oracle Cloud Computing Oracle Engineered Systems Oracle and Java SUBSCRIBE FEEDBACK PREVIOUS ISSUES "By taking part in marketing activities, our partners accelerate their sales cycles." -- Firstly, could you please explain Oracle's current strategy for ISV partners, globally and in EMEA? Oracle customers use independent software vendor (ISV) applications to run their businesses. They use them to generate revenue and to fulfil obligations to their own customers. Our strategy is very straight-forward. We want all of our ISV partners and OEMs to concentrate on the things that they do the best—building applications to meet the unique industry and functional requirements of their customer. We want to ensure that we deliver a best-in-class application platform so ISVs are free to concentrate their effort on their application functionality and user experience We invest over four billion dollars in research and development every year, and we want our ISVs to benefit from all of that investment in operating systems, virtualisation, databases, middleware, engineered systems, and other hardware. By doing this, we help them to reduce their costs, gain more consistency and agility for quicker implementations, and also rapidly differentiate themselves from other application vendors. It's all about simplification because we believe that around 25 to 30 percent of the development costs incurred by many ISVs are caused by customising infrastructure and have nothing to do with their applications. Our strategy is to enable our ISV partners to standardise their application platform using engineered architecture, so they can write once to the Oracle stack and deploy seamlessly in the cloud, on-premise, or in hybrid deployments. It's really important that architecture is the same in order to keep cost and time overheads at a minimum, so we provide standardisation and an environment that enables our ISVs to concentrate on the core business that makes them the most money and brings them success. How do you believe this strategy is helping the ISVs to work hand-in-hand with Oracle to ensure that end customers get the industry-leading solutions that they need? We work with our ISVs not just to help them be successful, but also to help them market themselves. We have something called the 'Oracle Exastack Ready Program', which enables ISVs to publicise themselves as 'Ready' to run the core software platforms that run on Oracle's engineered systems including Exadata and Exalogic. So, for example, they can become 'Database Ready' which means that they use the latest version of Oracle Database and therefore can run their application without modification on Exadata or the Oracle Database Appliance. Alternatively, they can become WebLogic Ready, Oracle Linux Ready and Oracle Solaris Ready which means they run on the latest release and therefore can run their application, with no new porting work, on Oracle Exalogic. Those 'Ready' logos are important in helping ISVs advertise to their customers that they are using the latest technologies which have been fully tested. We now also have Exadata Ready and Exalogic Ready programmes which allow ISVs to promote the certification of their applications on these platforms. This highlights these partners to Oracle customers as having solutions that run fluently on the Oracle Exadata Database Machine, the Oracle Exalogic Elastic Cloud or one of our other engineered systems. This makes it easy for customers to identify solutions and provides ISVs with an avenue to connect with Oracle customers who are rapidly adopting engineered systems. We have also taken this programme to the next level in the shape of 'Oracle Exastack Optimized' for partners whose applications run best on the Oracle stack and have invested the time to fully optimise application performance. We ensure that Exastack Optimized partner status is promoted and supported by press releases, and we help our ISVs go to market and differentiate themselves through the use of our technology and the standardisation it delivers. To date we have had several hundred organisations successfully work through our Exastack Optimized programme. How does Oracle's strategy of offering pre-integrated open platform software and hardware allow ISVs to bring their products to market more quickly? One of the problems for many ISVs is that they have to think very carefully about the technology on which their solutions will be deployed, particularly in the cloud or hosted environments. They have to think hard about how they secure these environments, whether the concern is, for example, middleware, identity management, or securing personal data. If they don't use the technology that we build-in to our products to help them to fulfil these roles, they then have to build it themselves. This takes time, requires testing, and must be maintained. By taking advantage of our technology, partners will now know that they have a standard platform. They will know that they can confidently talk about implementation being the same every time they do it. Very large ISV applications could once take a year or two to be implemented at an on-premise environment. But it wasn't just the configuration of the application that took the time, it was actually the infrastructure - the different hardware configurations, operating systems and configurations of databases and middleware. Now we strongly believe that it's all about standardisation and repeatability. It's about making sure that our partners can do it once and are then able to roll it out many different times using standard componentry. What actions would you recommend for existing ISV partners that are looking to do more business with Oracle and its customer base, not only to maximise benefits, but also to maximise partner relationships? My team, around the world and in the EMEA region, is available and ready to talk to any of our ISVs and to explore the possibilities together. We run programmes like 'Excite' and 'Insight' to help us to understand how we can help ISVs with architecture and widen their environments. But we also want to work with, and look at, new opportunities - for example, the Machine-to-Machine (M2M) market or 'The Internet of Things'. Over the next few years, many millions, indeed billions of devices will be collecting massive amounts of data and communicating it back to the central systems where ISVs will be running their applications. The only way that our partners will be able to provide a single vendor 'end-to-end' solution is to use Oracle integrated systems at the back end and Java on the 'smart' devices collecting the data—a complete solution from device to data centre. So there are huge opportunities to work closely with our ISVs, using Oracle's complete M2M platform, to provide the infrastructure that enables them to extract maximum value from the data collected. If any partners don't know where to start or who to contact, then they can contact me directly at [email protected] or indeed any of our teams across the EMEA region. We want to work with ISVs to help them to be as successful as they possibly can through simplification and speed to market, and we also want all of the top ISVs in the world based on Oracle. What opportunities are immediately opened to new ISV partners joining the OPN? As you know OPN is very, very important. New members will discover a huge amount of content that instantly becomes accessible to them. They can access a wealth of no-cost training and enablement materials to build their expertise in Oracle technology. They can download Oracle software and use it for development projects. They can help themselves become more competent by becoming part of a true community and uncovering new opportunities by working with Oracle and their peers in the Oracle Partner Network. As well as publishing massive amounts of information on OPN, we also hold our global Oracle OpenWorld event, at which partners play a huge role. This takes place at the end of September and the beginning of October in San Francisco. Attending ISV partners have an unrivalled opportunity to contribute to elements such as the OpenWorld / OPN Exchange, at which they can talk to other partners and really begin thinking about how they can move their businesses on and play key roles in a very large ecosystem which revolves around technology and standardisation. Finally, are there any other messages that you would like to share with the Oracle ISV community? The crucial message that I always like to reinforce is architecture, architecture and architecture! The key opportunities that ISVs have today revolve around standardising their architectures so that they can confidently think: "I will I be able to do exactly the same thing whenever a customer is looking to deploy on-premise, hosted or in the cloud". The right architecture is critical to being competitive and to really start changing the game. We want to help our ISV partners to do just that; to establish standard architecture and to seize the opportunities it opens up for them. New market opportunities like M2M are enormous - just look at how many devices are all around you right now. We can help our partners to interface with these devices more effectively while thinking about their entire ecosystem, rather than just the piece that they have traditionally focused upon. With standardised architecture, we can help people dramatically improve their speed, reach, agility and delivery of enhanced customer satisfaction and value all the way from the Java side to their centralised systems. All Oracle ISV partners must take advantage of these opportunities, which is why Oracle will continue to invest in and support them.

Madhivanan (SQL Server MVP) is a real community hero. He is known for his two skills – 1) Help Community and 2) Help Community. I have met him many times and every time I feel if anybody in online world needs help Madhinvanan does his best to reach them out and solve problem. His name is not new if you are ready this blog or have ever asked a question in any online SQL forum. He is always there to help. When Madhivanan has time he even helps people on this blog as well. He spends his valuable time to help community only. He recently crossed over 1000 helpful comments on this blog. On that occasion, I have interviewed him to find out if he has any life outside SQL. Q 1. Tell us something about your self. I am Madhivanan ,an MSc computer Science graduate from Chennai, India and working as a Lead Analyst-Project at Ellaar Infotek Solutions Private Limited. I am basically a developer started with Visual Basic 6.0, SQL Server 2000 and Crystal Report 8. As years go on I started working more on writing queries in SQL Server in most of the projects developed in my company. I have some good level of knowledge in ORACLE, MySQL and PostgreSQL as well. Now I am leading a project develeoped in Windows Azure. Q 2. What motivates you to help people on community and forums. When I got some errors during the application development in my early days of my career, I got good solutions from online forums and weblogs. So I decided to help others if possible. When I visit forums and help people if I know the answer to the questions. I am one of the leading posters at www.sqlteam.com and also a moderator at www.sql-server-performance.com. I also take part in Visual Basic and Crystal Reports forums. I have been SQL Server MVP since 2007. Q 3. Your personal life is not much known. Tell us something about your personal life. I am happily married person. My wife is a B.Pharm graduate. I have a son who is now 18 months old. Q 4. Where can we read further for your community activity. I have a blog at http://beyondrelational.com/blogs/madhivanan where you can find most of my T-sql stuffs Q 5. When not working with SQL what do you do? When not working with SQL, I spend time playing with my son, reading some magazines and watching TV. Madhivanan for your work and help to community, a true salute to you. Hats off my friend.

Protecting Consolidated Data on Engineered Systems

- by Steve Enevold

In this time of reduced budgets and cost cutting measures in Federal, State and Local governments, the requirement to provide services continues to grow. Many agencies are looking at consolidating their infrastructure to reduce cost and meet budget goals. Oracle's engineered systems are ideal platforms for accomplishing these goals. These systems provide unparalleled performance that is ideal for running applications and databases that traditionally run on separate dedicated environments. However, putting multiple critical applications and databases in a single architecture makes security more critical. You are putting a concentrated set of sensitive data on a single system, making it a more tempting target. The environments were previously separated by iron so now you need to provide assurance that one group, department, or application's information is not visible to other personnel or applications resident in the Exadata system. Administration of the environments requires formal separation of duties so an administrator of one application environment cannot view or negatively impact others. Also, these systems need to be in protected environments just like other critical production servers. They should be in a data center protected by physical controls, network firewalls, intrusion detection and prevention, etc Exadata also provides unique security benefits, including a reducing attack surface by minimizing packages and services to only those required. In addition to reducing the possible system areas someone may attempt to infiltrate, Exadata has the following features: 1. Infiniband, which functions as a secure private backplane 2. IPTables to perform stateful packet inspection for all nodes Cellwall implements firewall services on each cell using IPTables 3. Hardware accelerated encryption for data at rest on storage cells Oracle is uniquely positioned to provide the security necessary for implementing Exadata because security has been a core focus since the company's beginning. In addition to the security capabilities inherent in Exadata, Oracle security products are all certified to run in an Exadata environment. Database Vault Oracle Database Vault helps organizations increase the security of existing applications and address regulatory mandates that call for separation-of-duties, least privilege and other preventive controls to ensure data integrity and data privacy. Oracle Database Vault proactively protects application data stored in the Oracle database from being accessed by privileged database users. A unique feature of Database Vault is the ability to segregate administrative tasks including when a command can be executed, or that the DBA can manage the health of the database and objects, but may not see the data Advanced Security helps organizations comply with privacy and regulatory mandates by transparently encrypting all application data or specific sensitive columns, such as credit cards, social security numbers, or personally identifiable information (PII). By encrypting data at rest and whenever it leaves the database over the network or via backups, Oracle Advanced Security provides the most cost-effective solution for comprehensive data protection. Label Security is a powerful and easy-to-use tool for classifying data and mediating access to data based on its classification. Designed to meet public-sector requirements for multi-level security and mandatory access control, Oracle Label Security provides a flexible framework that both government and commercial entities worldwide can use to manage access to data on a "need to know" basis in order to protect data privacy and achieve regulatory compliance Data Masking reduces the threat of someone in the development org taking data that has been copied from production to the development environment for testing, upgrades, etc by irreversibly replacing the original sensitive data with fictitious data so that production data can be shared safely with IT developers or offshore business partners Audit Vault and Database Firewall Oracle Audit Vault and Database Firewall serves as a critical detective and preventive control across multiple operating systems and database platforms to protect against the abuse of legitimate access to databases responsible for almost all data breaches and cyber attacks. Consolidation, cost-savings, and performance can now be achieved without sacrificing security. The combination of built in protection and Oracle’s industry-leading data protection solutions make Exadata an ideal platform for Federal, State, and local governments and agencies.

Set JENKINS_HOME in Tomcat7?

- by C. Ross

I'm trying to set up Jenkins in Tomcat7 on Ubuntu. I installed Tomcat7 and deployed jenkins.war, and I now see the Jenkins home page at http://myhost:8080/jenkins, but it's attempting to create the Jenkins directory at /usr/share/tomcat7/.jenkins, which it can't for security reasons. I've already created /srv/jenkins and given the tomcat7 group permissions, and want to set JENKINS_HOME to that path. I've tried adding it to the tomcat configuration in /etc/tomcat7/server.xml: <GlobalNamingResources> <Environment name="JENKINS_HOME" value="/srv/jenkins" type="java.lang.String" override="false"/>  And I've also tried adding it to the automatically created context file in ROOT/META-INF/context.xml (there is no $CATALINA_HOME/conf as far as I can tell). <Context path="/" antiResourceLocking="false" > <Environment name="JENKINS_HOME" value="/srv/jenkins/" type="java.lang.String"/> </Context> But even after restarting tomcat7 I still get the same result (trying to use /usr/share/tomcat7/.jenkins). Where do I need to set the environment variable for JENKINS_HOME in Tomcat7?

the rmagick manual is quite vague. can you help me by changing a pictures filetype and size?

- by Joern Akkermann

Hi, it's about RMagick with Ruby On Rails. I do the following: image = params[:image] # params[:image] is the image from the file-form. name = image.original_filename.scan(/[^\/\\]+/).last name = dir + t.day.to_s + t.month.to_s + t.year.to_s + t.hour.to_s + t.min.to_s + t.sec.to_s + name f = File.new(name, "wb") f.write image f.close image = Magick::Image.read(name) image = image.resize_to_fit(200, 250) f = File.new(name, "wb") f.write image.to_blob f.close Do I really need to first save and then change it? And how about changing not only the size, changing also the Filetype? I want a JPG with 60% quality. Please help me. Yours, Joern.
