  • ODTUG is Looking for your ADF Feedback

    - by Shay Shmeltzer
    While we at Oracle are busy planning next month's Oracle OpenWorld - which should have one of the busiest schedule ever for ADF developers - another conference is also looking to know what you would like to learn about Oracle ADF. ODTUG is well on their way planning the upcoming KScope 13 conference - and they would like to better understand the needs of developers who are already working with ADF or of developers who are about to embark on their ADF road. They have put up a new short survey to collect your thoughts here. And while we are talking about KScrope it is worth mentioning that one easy way to get a free pass to that conference is to get accepted as a speaker and their call for papers is now open. Check it out and submit your ADF abstracts. And one last point about ODTUG - they just added several web seminars about ADF to their upcoming schedule of free online seminars - check it out and register now - membership is not required for attending the seminars.

  • Why are a seemingly disproportionate amount of programmers just, well, not nice?

    - by Macy Abbey
    Maybe it's just my personal experience, but I associate with varying different groups and types of people and it seems to me that an oddly large percentage of programmers I have encountered are "not nice" or for an attempt at a better definition: Condescending Snarky Negative in the way they talk about people If you have noticed the same thing, any theories as to why? Any suggestions on how to politely or not so politely let one of these programmers know how they are acting and suggest they correct it if they want to be perceived as professional one would want to work with? Or perhaps I've just come across a bad sample and there are bad seeds in every group of people one can name.

  • Mirroring Ubuntu on several systems in a computer lab

    - by Harvey Steck
    I am working in a new refugee school where the only Internet service available is a slow satellite connection. We are about to set up a computer lab (already have desktop systems and am about to install Ubuntu on them). I'm a newbie when it comes to Linux, but it seems a better alternative than pirated copies of Windows. I'd like to set up one Ubuntu system, and then mirror that system on perhaps ten to twenty other systems (all of which would be on an ethernet network). I expect to have an internet connection on the one system that I set up, but then it may be difficult to have enough bandwidth to go through all the same steps on the other ten systems. Can I set up the other ten or twenty computers to get all of their updates/upgrades/configuration from one master system? Can I also set things up so that students cannot change the configuration, install new programs, etc.? Appreciate any help you can give. -- Harvey

  • Professional Development – Difference Between Bio, CV and Resume

    - by Pinal Dave
    Applying for work can be very stressful – you want to put your best foot forward, and it can be very hard to sell yourself to a potential employer while highlighting your best characteristics and answering questions.  On top of that, some jobs require different application materials – a biography (or bio), a curriculum vitae (or CV), or a resume.  These things seem so interchangeable, so what is the difference? Let’s start with the one most of us have heard of – the resume.  A resume is a summary of your job and education history.  If you have ever applied for a job, you will have used a resume.  The ability to write a good resume that highlights your best characteristics and emphasizes your qualifications for a specific job is a skill that will take you a long way in the world.  For such an essential skill, unfortunately it is one that many people struggle with. RESUME So let’s discuss what makes a great resume.  First, make sure that your name and contact information are at the top, in large print (slightly larger font than the rest of the text, size 14 or 16 if the rest is size 12, for example).  You need to make sure that if you catch the recruiter’s attention and they know how to get a hold of you. As for qualifications, be quick and to the point.  Make your job title and the company the headline, and include your skills, accomplishments, and qualifications as bullet points.  Use good action verbs, like “finished,” “arranged,” “solved,” and “completed.”  Include hard numbers – don’t just say you “changed the filing system,” say that you “revolutionized the storage of over 250 files in less than five days.”  Doesn’t that sentence sound much more powerful? Curriculum Vitae (CV) Now let’s talk about curriculum vitae, or “CVs”.  A CV is more like an expanded resume.  The same rules are still true: put your name front and center, keep your contact info up to date, and summarize your skills with bullet points.  However, CVs are often required in more technical fields – like science, engineering, and computer science.  This means that you need to really highlight your education and technical skills. Difference between Resume and CV Resumes are expected to be one or two pages long – CVs can be as many pages as necessary.  If you are one of those people lucky enough to feel limited by the size constraint of resumes, a CV is for you!  On a CV you can expand on your projects, highlight really exciting accomplishments, and include more educational experience – including GPA and test scores from the GRE or MCAT (as applicable).  You can also include awards, associations, teaching and research experience, and certifications.  A CV is a place to really expand on all your experience and how great you will be in this particular position. Biography (Bio) Chances are, you already know what a bio is, and you have even read a few of them.  Think about the one or two paragraphs that every author includes in the back flap of a book.  Think about the sentences under a blogger’s photo on every “About Me” page.  That is a bio.  It is a way to quickly highlight your life experiences.  It is essentially the way you would introduce yourself at a party. Where a bio is required for a job, chances are they won’t want to know about where you were born and how many pets you have, though.  This is a way to summarize your entire job history in quick-to-read format – and sometimes during a job hunt, being able to get to the point and grab the recruiter’s interest is the best way to get your foot in the door.  Think of a bio as your entire resume put into words. Most bios have a standard format.  In paragraph one, talk about your most recent position and accomplishments there, specifically how they relate to the job you are applying for.  If you have teaching or research experience, training experience, certifications, or management experience, talk about them in paragraph two.  Paragraph three and four are for highlighting publications, education, certifications, associations, etc.  To wrap up your bio, provide your contact info and availability (dates and times). Where to use What? For most positions, you will know exactly what kind of application to use, because the job announcement will state what materials are needed – resume, CV, bio, cover letter, skill set, etc.  If there is any confusion, choose whatever the industry standard is (CV for technical fields, resume for everything else) or choose which of your documents is the strongest.

  • Backup files with rsync: error 23

    - by maria
    Hi I'm trying to make a backup of my /home to transfer all data from one computer to another. I wanted to save the backup on the same computer and than transfere it to another one. For safety reasons, I'm trying to learn how does it work on the computer without a lot of data (the new one) to be sure I won't delete something instead of copying it. I've run in terminal: sudo rsync -avz /home/maria /home/guest/backup and I had as the result: sent 58797801 bytes received 23050 bytes 4705668.08 bytes/sec total size is 100202958 speedup is 1.70 rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1060) [sender=3.0.7] I've tried once again, with the same result. I have no idea, which files were not transferred, what makes the whole backup useless for me (I wanted to do it automatically in order not to forget about something and loose it). On both computers I have the same system (Ubuntu 10.04). Rsync version: 3.0.7-1ubuntu1. Thanks for any tips

  • Unity3D - Projection matrix camera frustum

    - by MulletDevil
    I've used off centre projection to create a custom projection matrix for my camera. When I run the game I can see the scene correctly in the game view but in the editor view the camera frustum is not correct. It still shows the original frustum shape not the new one. It also appears that Unity is using the original frustum for frustum culling and not the new one as I can see object being culled which are visible to the new frustum but would not be visible in the old one. Am I wrong in thinking that a custom projection matrix would alter the view frustum? Or am I missing something else?

  • Detecting long held keys on keyboard

    - by Robinson Joaquin
    I just want to ask if can I check for "KEY"(keyboard) that is HOLD/PRESSED for a long time, because I am to create a clone of breakout with air hockey for 2 different human players. Here's the list of my concern: Do I need other/ 3rd party library for KEY HOLDS? Is multi-threading needed? I don't know anything about this multi-threading stuff and I don't think about using one(I'm just a NEWBIE). One more thing, what if the two players pressed their respective key at the same time, how can I program to avoid error or worse one player's key is prioritized first before the the key of the other. example: Player 1 = W for UP & S for DOWN Player 2 = O for UP & L for DOWN (example: W & L is pressed at the same time) PS: I use GLUT for the visuals of the game.

  • managing information/functionality on shared common project classes

    - by ilansch
    In my company, we have a common solution the contains common projects (2 projects so far, one for .net 3.5 and one for .net 4.5). My main problem is that during time, a lot of code is added, for example hosting a process as windows service is a class called ServiceManagement, But no one but the developer knows it, and if someone wants to use this shared class, he does not know it exist. So i am looking for a way to document and manage all the classes with tags, a 3rd party util/web util, that i can search for tags and maybe find common classes that i can use (if we keep all our code well-documented). Does anyone familiar with sort of tools ?

  • XML: Multiple roots + text content outside the root. Does anyone do it?

    - by Jeffrey Sweeney
    I have another one of those "is it done in XML" questions (my last one about xml comments hasn't been answered if anyone has a good explanation) I was just wondering if anyone, anywhere would: Use multiple root elements in an XML document Put text content outside of a root element W3C discourages these practices, Javascript's DOMParser doesn't even allow these cases, and I can't think of one sane reason to do either of these things. However, I know how bizarre some implementations of XML have been, so I wouldn't be surprised. Does anyone have any real world examples where this would be done? I will also accept an answer that specifies if other mainstream parsers allow doing either of these.

  • What's the format of Real World Performance Day?

    - by william.hardie
    A question that has cropped a lot of late is "what's the format of Real World Performance Day?" Not an unreasonable question you might think. Sure enough, a quick check of the Independent Oracle User Group's website tells us a bit about the Real World Performance Day event, but no formal agenda? This was one of the questions I posed to Tom Kyte (one of the main presenters) in our recent podcast. Tom tells us that this isn't your traditional event where one speaker follows another with loads of slides. In fact, the Real World Performance Day features Tom and fellow Oracle performance experts - Andrew Holdsworth and Graham Wood - continuously on stage throughout the day. All three will be discussing database performance challenges and solutions from development, architectural design and management perspectives. There's going to be multi-terabyte demos on show, less of the traditional slides, and more interactive debate and discussion going on. Tune-in and hear what else Tom has to say about this fairly unique event!

  • Javascript Rookie Question: Define Variables Inline

    - by Dylan Kinnett
    I'm proficient with HTML and CSS but I'm still pretty shaky when it comes to Javascript. That said, I've been able to build a site using the Internet Archive Book Reader, which relies on reader.js Here's a copy of one of my versions of reader.js https://gist.github.com/dylan-k/ed4efed2384e221d46cc It's a good site, but I find I have to repeat things a lot. Basically, I have one copy of reader.js for every page/book featured on the site. It seems there must be a better way. I re-use the script, making copies, just so that I can change lines 28, 80, 83, 84. Is there a way I could include just one copy of reader.js and then use a <script> tag to define these 4 lines for the individual pages?

  • C#/.NET Little Wonders &ndash; Cross Calling Constructors

    - by James Michael Hare
    Just a small post today, it’s the final iteration before our release and things are crazy here!  This is another little tidbit that I love using, and it should be fairly common knowledge, yet I’ve noticed many times that less experienced developers tend to have redundant constructor code when they overload their constructors. The Problem – repetitive code is less maintainable Let’s say you were designing a messaging system, and so you want to create a class to represent the properties for a Receiver, so perhaps you design a ReceiverProperties class to represent this collection of properties. Perhaps, you decide to make ReceiverProperties immutable, and so you have several constructors that you can use for alternative construction: 1: // Constructs a set of receiver properties. 2: public ReceiverProperties(ReceiverType receiverType, string source, bool isDurable, bool isBuffered) 3: { 4: ReceiverType = receiverType; 5: Source = source; 6: IsDurable = isDurable; 7: IsBuffered = isBuffered; 8: } 9: 10: // Constructs a set of receiver properties with buffering on by default. 11: public ReceiverProperties(ReceiverType receiverType, string source, bool isDurable) 12: { 13: ReceiverType = receiverType; 14: Source = source; 15: IsDurable = isDurable; 16: IsBuffered = true; 17: } 18:  19: // Constructs a set of receiver properties with buffering on and durability off. 20: public ReceiverProperties(ReceiverType receiverType, string source) 21: { 22: ReceiverType = receiverType; 23: Source = source; 24: IsDurable = false; 25: IsBuffered = true; 26: } Note: keep in mind this is just a simple example for illustration, and in same cases default parameters can also help clean this up, but they have issues of their own. While strictly speaking, there is nothing wrong with this code, logically, it suffers from maintainability flaws.  Consider what happens if you add a new property to the class?  You have to remember to guarantee that it is set appropriately in every constructor call. This can cause subtle bugs and becomes even uglier when the constructors do more complex logic, error handling, or there are numerous potential overloads (especially if you can’t easily see them all on one screen’s height). The Solution – cross-calling constructors I’d wager nearly everyone knows how to call your base class’s constructor, but you can also cross-call to one of the constructors in the same class by using the this keyword in the same way you use base to call a base constructor. 1: // Constructs a set of receiver properties. 2: public ReceiverProperties(ReceiverType receiverType, string source, bool isDurable, bool isBuffered) 3: { 4: ReceiverType = receiverType; 5: Source = source; 6: IsDurable = isDurable; 7: IsBuffered = isBuffered; 8: } 9: 10: // Constructs a set of receiver properties with buffering on by default. 11: public ReceiverProperties(ReceiverType receiverType, string source, bool isDurable) 12: : this(receiverType, source, isDurable, true) 13: { 14: } 15:  16: // Constructs a set of receiver properties with buffering on and durability off. 17: public ReceiverProperties(ReceiverType receiverType, string source) 18: : this(receiverType, source, false, true) 19: { 20: } Notice, there is much less code.  In addition, the code you have has no repetitive logic.  You can define the main constructor that takes all arguments, and the remaining constructors with defaults simply cross-call the main constructor, passing in the defaults. Yes, in some cases default parameters can ease some of this for you, but default parameters only work for compile-time constants (null, string and number literals).  For example, if you were creating a TradingDataAdapter that relied on an implementation of ITradingDao which is the data access object to retreive records from the database, you might want two constructors: one that takes an ITradingDao reference, and a default constructor which constructs a specific ITradingDao for ease of use: 1: public TradingDataAdapter(ITradingDao dao) 2: { 3: _tradingDao = dao; 4:  5: // other constructor logic 6: } 7:  8: public TradingDataAdapter() 9: { 10: _tradingDao = new SqlTradingDao(); 11:  12: // same constructor logic as above 13: }   As you can see, this isn’t something we can solve with a default parameter, but we could with cross-calling constructors: 1: public TradingDataAdapter(ITradingDao dao) 2: { 3: _tradingDao = dao; 4:  5: // other constructor logic 6: } 7:  8: public TradingDataAdapter() 9: : this(new SqlTradingDao()) 10: { 11: }   So in cases like this where you have constructors with non compiler-time constant defaults, default parameters can’t help you and cross-calling constructors is one of your best options. Summary When you have just one constructor doing the job of initializing the class, you can consolidate all your logic and error-handling in one place, thus ensuring that your behavior will be consistent across the constructor calls. This makes the code more maintainable and even easier to read.  There will be some cases where cross-calling constructors may be sub-optimal or not possible (if, for example, the overloaded constructors take completely different types and are not just “defaulting” behaviors). You can also use default parameters, of course, but default parameter behavior in a class hierarchy can be problematic (default values are not inherited and in fact can differ) so sometimes multiple constructors are actually preferable. Regardless of why you may need to have multiple constructors, consider cross-calling where you can to reduce redundant logic and clean up the code.   Technorati Tags: C#,.NET,Little Wonders

  • Coping with infrastructure upgrades

    - by Fatherjack
    A common topic for questions on SQL Server forums is how to plan and implement upgrades to SQL Server. Moving from old to new hardware or moving from one version of SQL Server to another. There are other circumstances where upgrades of other systems affect SQL Server DBAs. For example, where I work at the moment there is an Microsoft Exchange (email) server upgrade in progress. It it being handled by a different team so I’m not wholly sure on the details but we are in a situation where there are currently 2 Exchange email servers – the old one and the new one. Users mail boxes are being transferred in a planned process but as we approach the old server being turned off we have to also make sure that our SQL Servers get updated to use the new SMTP server for all of the SQL Agent notifications, SSIS packages etc. My servers have a number of profiles so that various jobs can send emails on behalf of various departments and different systems. This means there are lots of places that the old server name needs to be replaced by the new one. Anyone who has set up DBMail and enjoyed the click-tastic odyssey of screens to create Profiles and Accounts and so on and so forth ought to seek some professional help in my opinion. It’s a nightmare of back and forth settings changes and it stinks. I wasn’t looking forward to heading into this mess of a UI and changing the old Exchange server name for the new one on all my SQL Instances for all of the accounts I have set up. So I did what any Englishmen with a shed would do, I decided to take it apart and see if I can fix it another way. I took a guess that we are going to be working in MSDB and Books OnLine was remarkably helpful and amongst a lot of information told me about a couple of procedures that can be used to interrogate DBMail settings. USE [msdb] -- It's where all the good stuff is kept GO EXEC dbo.sysmail_help_profile_sp; EXEC dbo.sysmail_help_account_sp; Both of these procedures take optional parameters with the same name – ID and Name. If you provide an ID or a name then the results you get back are for that specific Profile or Account. Otherwise you get details of all Profiles and Accounts on the server you are connected to. As you can see (click for a bigger image), the Account has the SMTP server information in the servername column. We want to change that value to NewSMTP.Contoso.com. Now it appears that the procedure we are looking at gets it’s data from the sysmail_account and sysmail_server tables, you can get the results the stored procedure provides if you run the code below. SELECT [account_id] , [name] , [description] , [email_address] , [display_name] , [replyto_address] , [last_mod_datetime] , [last_mod_user] FROM dbo.sysmail_account AS sa; SELECT [account_id] , [servertype] , [servername] , [port] , [username] , [credential_id] , [use_default_credentials] , [enable_ssl] , [flags] , [last_mod_datetime] , [last_mod_user] , [timeout] FROM dbo.sysmail_server AS sms Now, we have no real idea how these tables are linked and whether making an update direct to one or other of them is going to do what we want or whether it will entirely cripple our ability to send email from SQL Server so we wont touch those tables with any UPDATE TSQL. So, back to Books OnLine then and we find sysmail_update_account_sp. It’s exactly what we need. The examples in BOL take the form (as below) of having every parameter explicitly defined. Not wanting to totally obliterate the existing values by not passing values in all of the parameters I set to writing some code to gather the existing data from the tables and re-write the SMTP server name and then execute the resulting TSQL. IF OBJECT_ID('tempdb..#sysmailprofiles') IS NOT NULL DROP TABLE #sysmailprofiles GO CREATE TABLE #sysmailprofiles ( account_id INT , [name] VARCHAR(50) , [description] VARCHAR(500) , email_address VARCHAR(500) , display_name VARCHAR(500) , replyto_address VARCHAR(500) , servertype VARCHAR(10) , servername VARCHAR(100) , port INT , username VARCHAR(100) , use_default_credentials VARCHAR(1) , ENABLE_ssl VARCHAR(1) ) INSERT [#sysmailprofiles] ( [account_id] , [name] , [description] , [email_address] , [display_name] , [replyto_address] , [servertype] , [servername] , [port] , [username] , [use_default_credentials] , [ENABLE_ssl] ) EXEC [dbo].[sysmail_help_account_sp] DECLARE @TSQL NVARCHAR(1000) SELECT TOP 1 @TSQL = 'EXEC [dbo].[sysmail_update_account_sp] @account_id = ' + CAST([s].[account_id] AS VARCHAR(20)) + ', @account_name = ''' + [s].[name] + '''' + ', @email_address = N''' + [s].[email_address] + '''' + ', @display_name = N''' + [s].[display_name] + '''' + ', @replyto_address = N''' + s.replyto_address + '''' + ', @description = N''' + [s].[description] + '''' + ', @mailserver_name = ''NEWSMTP.contoso.com''' + +', @mailserver_type = ' + [s].[servertype] + ', @port = ' + CAST([s].[port] AS VARCHAR(20)) + ', @username = ' + COALESCE([s].[username], '''''') + ', @use_default_credentials =' + CAST(s.[use_default_credentials] AS VARCHAR(1)) + ', @enable_ssl =' + [s].[ENABLE_ssl] FROM [#sysmailprofiles] AS s WHERE [s].[servername] = 'SMTP.Contoso.com' SELECT @tsql EXEC [sys].[sp_executesql] @tsql This worked well for me and testing the email function EXEC dbo.sp_send_dbmail afterwards showed that the settings were indeed using our new Exchange server. It was only later in writing this blog that I tried running the sysmail_update_account_sp procedure with only the SMTP server name parameter value specified. Despite what Books OnLine might intimate, you can do this and only the values for parameters specified get changed. If a parameter is not specified in the execution of the procedure then the values remain unchanged. This renders most of the above script unnecessary as I could have simply specified the account_id that I want to amend and the new value for the parameter I want to update. EXEC sysmail_update_account_sp @account_id = 1, @mailserver_name = 'NEWSMTP.Contoso.com' This wasn’t going to be the main reason for this post, it was meant to describe how to capture values from a stored procedure and use them in dynamic TSQL but instead we are here and (re)learning the fact that Books Online is a little flawed in places. It is a fantastic resource for anyone working with SQL Server but the reader must adopt an enquiring frame of mind and use a little curiosity to try simple variations on examples to fully understand the code you are working with. I think the author(s) of this part of Books OnLine missed an opportunity to include a third example that had fewer than all parameters specified to give a lead to this method existing.

  • rails fake data, considering switch from faker to forgery, any advantages or pitfalls?

    - by Michael Durrant
    With Ruby on Rails I've usually used Forgery for generating dummy data for testing. I've noticed recently that several clients and tutorials are using Faker They both seem fairly similar in use and popularity: Faker 128 forks, 418 watchers. Forgery 59 forks, 399 watchers. They both seem similar in how current they are: Faker Most updates are from 6 and 9 months ago. Forgery Most updates are from 4 and 9 months ago. The one distinguishing factor I've found so far is that Forgery seems like it has better instructions. Are there any particular benefits or disadvantages to using one over the other? Have you ever needed to switch from one to another for a particular reason?

  • What makes a good developer / system documentation?

    - by deamon
    Much time is wasted to get new developers started with existing software systems, because there is no good documenation. But what makes a system documentation good? One thing is a good API documentation like the Java API doc, but how to transfer the "bigger picture" and other things that cannot be placed in the API doc? One constraint is that it should not be to hard and time consuming to write the docs, because that is one reason why it is omitted so often. So, what makes documentation good?

  • Renewing a SSL certificate with GoDaddy

    - by Flavien
    GoDaddy sells SSL certificates for $12 per year (the most basic one). I have bought one of those last year, and now is the time to renew. However they are now asking for $50 for the renewal (the $12 is apparently a discount). Is there a way to get the $12 price for a renewal. Is it going to work if I buy a new certificate at $12, and use the same host as the one I had before, or are they going to prevent me from doing that?

  • New to world of Ubuntu

    I've been running Ubuntu 13.04 since June 2013, and upgrading to 13.10 as we speak.(Note I own total 3 laptops.) My goal is to have one complete Linux machine and one dual boot, and third well (he is a newer Lenovo with Windows 8.1 and is touch screen.) but I want to learn Ubuntu life and further myself with using it for everyday use, but I'm not very fluid in Linux usage and hoping to find people who have a love for teaching others how to be one with the BEST OS IN THE WORLD! Hope I've got few people wanting to teach or give good instruction for success. ~Mike Cheney~

  • Why is using C++ libraries so complicated?

    - by Pius
    First of all, I want to note I love C++ and I'm one of those people who thinks it is easier to code in C++ than Java. Except for one tiny thing: libraries. In Java you can simply add some jar to the build path and you're done. In C++ you usually have to set multiple paths for the header files and the library itself. In some cases, you even have to use special build flags. I have mainly used Visual Studio, Code Blocks and no IDE at all. All 3 options do not differ much when talking about using external libraries. I wonder why was there made no simpler alternative for this? Like having a special .zip file that has everything you need in one place so the IDE can do all the work for you setting up the build flags. Is there any technical barrier for this?

  • Creating the Business Card Request InfoPath Form

    - by JKenderdine
    Business Card Request Demo Files Back in January I spoke at SharePoint Saturday Virginia Beach about InfoPath forms and Web Part deployment.  Below is some of the information and details regarding the form I created for the session.  There are many blogs and Microsoft articles on how to create a basic form so I won’t repeat that information here.   This blog will just explain a few of the options I chose when creating the solutions for SPS Virginia Beach.  The above link contains the zipped package files of the two InfoPath forms(no code solution and coded solution), the list template for the Location list I used, and the PowerPoint deck.  If you plan to use these templates, you will need to update the forms to work within your own environments (change data connections, code links, etc.).  Also, you must have the SharePoint Enterprise version, with InfoPath Services configured in order to use the Web Browser enabled forms. So what are the requirements for this template? Business Card Request Form Template Design Plan: Gather user information and requirements for card Pull in as much user information as possible. Use data from the user profile web services as a data source Show and hide fields as necessary for requirements Create multiple views – one for those submitting the form and Another view for the executive assistants placing the orders. Browser based form integrated into SharePoint team site Submitted directly to form library The base form was created using the blank template.  The table and rows were added using Insert tab and selecting Custom Table.  The use of tables is a great way to make sure everything lines up.  You do have to split the tables from time to time.  If you’ve ever split cells and then tried to re-align one to find that you impacted the others, you know why.  Here is what the base form looks like in InfoPath.   Show and hide fields as necessary for requirements You will notice I also used Sections within the form.  These show or hide depending on options selected or whether or not fields are blank.  This is a great way to prevent your users from feeling overwhelmed with a large form (this one wouldn’t apply).  Although not used in this one, you can also use various views with a tab interface.  I’ll show that in another post. Gather user information and requirements for card Pull in as much user information as possible. Use data from the user profile web services as a data source Utilizing rules you can load data when the form initiates (Data tab, Form Load).  Anything you can automate is always appreciated by the user as that is data they don’t have to enter.  For example, loading their user id or other user information on load: Always keep in mind though how much data you load and the method for loading that data (through rules, code, etc.).  They have an impact on form performance.  The form will take longer to load if you bring in a ton of data from external sources.  Laura Rogers has a great blog post on using the User Information List to load user information.   If the user has logged into SharePoint, then this can be used quite effectively and without a huge performance hit.   What I have found is that using the User Profile service via code behind or the Web Service “GetUserProfileByName” (as above) can take more time to load the user data.  Just food for thought. You must add the data connection in order for the above rules to work.  You can connect to the data connection through the Data tab, Data Connections or select Manage Data Connections link which appears under the main data source.  The data connections can be SharePoint lists or libraries, SQL data tables, XML files, etc.  Create multiple views – one for those submitting the form and Another view for the executive assistants placing the orders. You can also create multiple views for the users to enhance their experience.  Once they’ve entered the information and submitted their request for business cards, they don’t really need to see the main data input screen any more.  They just need to view what they entered. From the Page Design tab, select New View and give the view a name.  To review the existing views, click the down arrow under View: The ReviewView shows just what the user needs and nothing more: Once you have everything configured, the form should be tested within a Test SharePoint environment before final deployment to production.  This validates you don’t have any rules or code that could impact the server negatively. Submitted directly to form library   You will need to know the form library that you will be submitting to when publishing the template.  Configure the Submit data connection to connect to this library.  There is already one configured in the sample,  but it will need to be updated to your environment prior to publishing. The Design template is different from the Published template.  While both have the .XSN extension, the published template contains all the “package” information for the form.  The published form is what is loaded into Central Admin, not the design template. Browser based form integrated into SharePoint team site In Central Admin, under General Settings, select Manage Form Templates.  Upload the published form template and Activate it to a site collection. Now it is available as a content type to select in the form library.  Some documentation on publishing form templates:  Technet – Manage administrator approved form templates And that’s all our base requirements.  Hope this helps to give a good start.

  • Exposing warnings\errors from data objects (that are also list returned)

    - by Oren Schwartz
    I'm exposing Data objects via service oriented assembly (which on future usages might become a WCF service). The data object is tree designed, as well as formed from allot of properties.Moreover, some services return one objects, others retrieve a list of them (thus disables throwing exceptions). I now want to expose data flow warnings and wondering what's the best way to do it having to things to consider: (1) seperation (2) ease of access. On the one hand, i want the UI team to be able to access a fields warnings (or errors) without having them mapping the field names to an external source but on the other hand, i don't want the warnings "hanged" on the object itself (as i don't see it a correct design). I tought of creating a new type of wrapper for each field, that'll expose events and they'll have to register the one's they care about (but totally not sure) I'll be happy to hear your thoughts. Could you please direct me to a respectful design pattern ? what dp will do best here ? Thank you very much!

  • Should I use both WCF and ASP.NET Web API

    - by Mithir
    We already have a WCF API with basichttpbinding. Some of the calls have complex objects in both the response and request. We need to add RESTful abilities to the API. at first I tried adding a webHttp endpoint, but I got At most one body parameter can be serialized without wrapper elements If I made it Wrapped it wasn't pure as I need it to be. I got to read this, and this (which states "ASP.NET Web API is the new way to build RESTful service on .NET"). So my question is, should I make 2 APIs(2 different projects)? one for SOAP with WCF and one RESTful with ASP.NET Web API? is there anything wrong architecturally speaking with this approach?

  • Android - Rendering HUD View to SurfaceView

    - by Jon
    I have developed a relatively simple game in android, to get my head around it all, and on the back of it developed a crude game engine (in the loosest sense!). I use a SurfaceView and canvas (no OpenGL) - I'll cross that bridge another time! I have implemented a game HUD, title screens etc. by overlaying standard Android view widgets over my SurfaceView. This all works reasonably well maintaining an acceptable frame-rate, but it is a simple game with not a lot happening on or off screen. What I am wondering now is whether one could (and whether one would get any advantage by) drawing all my views to the one SurfaceView, all controlled by the main game thread. At the moment I have handlers flinging messages around and runOnUiThreads here, there and everywhere. Quite cumbersome. Any thoughts on this would be much appreciated (before I perhaps waste time trying to do it!)
