  • enums in C# - assignment

    - by Zka
    How does one do this in c#? Let's say that myclass has : private enum Days{}; 1) How does one add data to the enum inside the myclass with the help of the constructor? As in : myclass my = new myclass(Monday,Friday); so that the enum inside the class gets the "Monday, Friday" properties. 2) Can one also make a property for an enume inside the class once it is initialized ? For example : my.Days = new enum Days(Tuesday); //where the old settings are replaced.

  • Use WPF DLL Assembly in ASP.NET problem

    - by liimur
    Hello, I have C++ project that compiles as DLL Assembly in .NET 3.5 SP1 Project is used for Image rendering processing by using WPF (it loads 2 images from local folder, applies one image on another and saves the output file in the same folder). I want to use that that project as a reference in ASP.NET project to the rendering on the website. So I created simple Web Project in ASP.NET C# that uses C++ project as a Reference. Everything works great in ASP.NET Web Development Server (built-in Web server in VS2008). But once I publish this project to IIS on the same Machine or use IIS for debug instead of built-in Web server Image rendering it's not working anymore. I'm not getting any exceptions or error messages, it just output image is not processes as it supposed to be. If anyone know what could cause that I would really appreciate your insight!

  • Some non-generic collections

    - by Simon Cooper
    Although the collections classes introduced in .NET 2, 3.5 and 4 cover most scenarios, there are still some .NET 1 collections that don't have generic counterparts. In this post, I'll be examining what they do, why you might use them, and some things you'll need to bear in mind when doing so. BitArray System.Collections.BitArray is conceptually the same as a List<bool>, but whereas List<bool> stores each boolean in a single byte (as that's what the backing bool[] does), BitArray uses a single bit to store each value, and uses various bitmasks to access each bit individually. This means that BitArray is eight times smaller than a List<bool>. Furthermore, BitArray has some useful functions for bitmasks, like And, Xor and Not, and it's not limited to 32 or 64 bits; a BitArray can hold as many bits as you need. However, it's not all roses and kittens. There are some fundamental limitations you have to bear in mind when using BitArray: It's a non-generic collection. The enumerator returns object (a boxed boolean), rather than an unboxed bool. This means that if you do this: foreach (bool b in bitArray) { ... } Every single boolean value will be boxed, then unboxed. And if you do this: foreach (var b in bitArray) { ... } you'll have to manually unbox b on every iteration, as it'll come out of the enumerator an object. Instead, you should manually iterate over the collection using a for loop: for (int i=0; i<bitArray.Length; i++) { bool b = bitArray[i]; ... } Following on from that, if you want to use BitArray in the context of an IEnumerable<bool>, ICollection<bool> or IList<bool>, you'll need to write a wrapper class, or use the Enumerable.Cast<bool> extension method (although Cast would box and unbox every value you get out of it). There is no Add or Remove method. You specify the number of bits you need in the constructor, and that's what you get. You can change the length yourself using the Length property setter though. It doesn't implement IList. Although not really important if you're writing a generic wrapper around it, it is something to bear in mind if you're using it with pre-generic code. However, if you use BitArray carefully, it can provide significant gains over a List<bool> for functionality and efficiency of space. OrderedDictionary System.Collections.Specialized.OrderedDictionary does exactly what you would expect - it's an IDictionary that maintains items in the order they are added. It does this by storing key/value pairs in a Hashtable (to get O(1) key lookup) and an ArrayList (to maintain the order). You can access values by key or index, and insert or remove items at a particular index. The enumerator returns items in index order. However, the Keys and Values properties return ICollection, not IList, as you might expect; CopyTo doesn't maintain the same ordering, as it copies from the backing Hashtable, not ArrayList; and any operations that insert or remove items from the middle of the collection are O(n), just like a normal list. In short; don't use this class. If you need some sort of ordered dictionary, it would be better to write your own generic dictionary combining a Dictionary<TKey, TValue> and List<KeyValuePair<TKey, TValue>> or List<TKey> for your specific situation. ListDictionary and HybridDictionary To look at why you might want to use ListDictionary or HybridDictionary, we need to examine the performance of these dictionaries compared to Hashtable and Dictionary<object, object>. For this test, I added n items to each collection, then randomly accessed n/2 items: So, what's going on here? Well, ListDictionary is implemented as a linked list of key/value pairs; all operations on the dictionary require an O(n) search through the list. However, for small n, the constant factor that big-o notation doesn't measure is much lower than the hashing overhead of Hashtable or Dictionary. HybridDictionary combines a Hashtable and ListDictionary; for small n, it uses a backing ListDictionary, but switches to a Hashtable when it gets to 9 items (you can see the point it switches from a ListDictionary to Hashtable in the graph). Apart from that, it's got very similar performance to Hashtable. So why would you want to use either of these? In short, you wouldn't. Any gain in performance by using ListDictionary over Dictionary<TKey, TValue> would be offset by the generic dictionary not having to cast or box the items you store, something the graphs above don't measure. Only if the performance of the dictionary is vital, the dictionary will hold less than 30 items, and you don't need type safety, would you use ListDictionary over the generic Dictionary. And even then, there's probably more useful performance gains you can make elsewhere.

  • File upload help in JSP /Struts 1.2

    - by user57421
    Hi All, I have seen lot of reviews and have not been able to figure out how I can solve my problem.. Problem: Currently we have a page to upload the file from local machine to the respositry. It is currently using Struts upload. Now the current requirment is, Since users upload around 1gb of file, they are made to wait for a long time.. So they changed the requirment to browse the file and select the file to upload and hitting upload button should return to the control to next screen imediately.. But the upload process some how needs to be pushed at the backend and should do the upload and send out an email once the upload is complete.. I'm not able to figure out how to transfer the control to next page, when the upload is still running ... any idea or help will be appreicated.. Regards, Senny

  • SSIS: Building SQL databases on-the-fly using concatenated SQL scripts

    - by DrJohn
    Over the years I have developed many techniques which help automate the whole SQL Server build process. In my current process, where I need to build entire OLAP data marts on-the-fly, I make regular use of a simple but very effective mechanism to concatenate all the SQL Scripts together from my SSMS (SQL Server Management Studio) projects. This proves invaluable because in two clicks I can redeploy an entire SQL Server database with all tables, views, stored procedures etc. Indeed, I can also use the concatenated SQL scripts with SSIS to build SQL Server databases on-the-fly. You may be surprised to learn that I often redeploy the database several times per day, or even several times per hour, during the development process. This is because the deployment errors are logged and you can quickly see where SQL Scripts have object dependency errors. For example, after changing a table structure you may have forgotten to change any related views. The deployment log immediately points out all the objects which failed to build so you can fix and redeploy the database very quickly. The alternative approach (i.e. doing changes in the database directly using the SSMS UI) would require you to check all dependent objects before making changes. The chances are that you will miss something and wonder why your app returns the wrong data – a common problem caused by changing a table without re-creating dependent views. Using SQL Projects in SSMS A great many developers fail to make use of SQL Projects in SSMS (SQL Server Management Studio). To me they are invaluable way of organizing your SQL Scripts. The screenshot below shows a typical SSMS solution made up of several projects – one project for tables, another for views etc. The key point is that the projects naturally fall into the right order in file system because of the project name. The number in the folder or file name ensures that the projects the SQL scripts are concatenated together in the order that they need to be executed. Hence the script filenames start with 100, 110 etc. Concatenating SQL Scripts To concatenate the SQL Scripts together into one file, I use notepad.exe to create a simple batch file (see example screenshot) which uses the TYPE command to write the content of the SQL Script files into a combined file. As the SQL Scripts are in several folders, I simply use several TYPE command multiple times and append the output together. If you are unfamiliar with batch files, you may not know that the angled bracket (>) means write output of the program into a file. Two angled brackets (>>) means append output of this program into a file. So the command-line DIR > filelist.txt would write the content of the DIR command into a file called filelist.txt. In the example shown above, the concatenated file is called SB_DDS.sql If, like me you place the concatenated file under source code control, then the source code control system will change the file's attribute to "read-only" which in turn would cause the TYPE command to fail. The ATTRIB command can be used to remove the read-only flag. Using SQLCmd to execute the concatenated file Now that the SQL Scripts are all in one big file, we can execute the script against a database using SQLCmd using another batch file as shown below: SQLCmd has numerous options, but the script shown above simply executes the SS_DDS.sql file against the SB_DDS_DB database on the local machine and logs the errors to a file called SB_DDS.log. So after executing the batch file you can simply check the error log to see if your database built without a hitch. If you have errors, then simply fix the source files, re-create the concatenated file and re-run the SQLCmd to rebuild the database. This two click operation allows you to quickly identify and fix errors in your entire database definition.Using SSIS to execute the concatenated file To execute the concatenated SQL script using SSIS, you simply drop an Execute SQL task into your package and set the database connection as normal and then select File Connection as the SQLSourceType (as shown below). Create a file connection to your concatenated SQL script and you are ready to go.   Tips and TricksAdd a new-line at end of every fileThe most common problem encountered with this approach is that the GO statement on the last line of one file is placed on the same line as the comment at the top of the next file by the TYPE command. The easy fix to this is to ensure all your files have a new-line at the end.Remove all USE database statementsThe SQLCmd identifies which database the script should be run against.  So you should remove all USE database commands from your scripts - otherwise you may get unintentional side effects!!Do the Create Database separatelyIf you are using SSIS to create the database as well as create the objects and populate the database, then invoke the CREATE DATABASE command against the master database using a separate package before calling the package that executes the concatenated SQL script.

  • Why does the ASP.Net Web Forms model "suck"?

    - by Daniel Magliola
    I've heard Jeff Atwood, Joel Spolsky, and many other legendary people talk about how the ASP.Net Web Forms model sucks. (So this question is kind of directed to them, hopefully Jeff is reading) Now, I highly respect their opinion, given their background and expertise, but truth be told, I absolutely LOVE ASP.Net. I think the model is brilliant, and it sucks if you have no idea what you're doing, but once you understand how to control ViewState, when to use handlers instead of pages, etc, it is generations ahead of all the other models. So every time I hear someone complain about how it sucks, I can't help ask the same question... Why? What is it that's so bad about it? I appreciate all opinions. I'm assuming there's probably a post at Jeff's blog talking about this too...

  • Image Viewer application, Image processing with Display Data.

    - by Harsha
    Hello All, I am working on Image Viewer application and planning to build in WPF. My Image size are usually larger than 3000x3500. After searching for week, I got sample code from MSDN. But it is written in ATL COM. So I am planning to work and build the Image viewer as follows: After reading the Image I will scale down to my viewer size, viwer is around 1000x1000. Lets call this Image Data as Display Data. Once displaying this data, I will work only this Display data. For all Image processing operation, I will use this display data and when user choose to save the image, I will apply all the operation to original Image data. My question is, Is is ok to use Display data for showing and initial image processing operations.

  • BigDecimal precision not persisted with javax.persistence annotations

    - by dkaczynski
    I am using the javax.persistence API and Hibernate to create annotations and persist entities and their attributes in an Oracle 11g Express database. I have the following attribute in an entity: @Column(precision = 12, scale = 9) private BigDecimal weightedScore; The goal is to persist a decimal value with a maximum of 12 digits and a maximum of 9 of those digits to the right of the decimal place. After calculating the weightedScore, the result is 0.1234, but once I commit the entity with the Oracle database, the value displays as 0.12. I can see this by either by using an EntityManager object to query the entry or by viewing it directly in the Oracle Application Express (Apex) interface in a web browser. How should I annotate my BigDecimal attribute so that the precision is persisted correctly? Note: We use an in-memory HSQL database to run our unit tests, and it does not experience the issue with the lack of precision, with or without the @Column annotation.

  • How fast can you make linear search?

    - by Mark Probst
    I'm looking to optimize this linear search: static int linear (const int *arr, int n, int key) { int i = 0; while (i < n) { if (arr [i] >= key) break; ++i; } return i; } The array is sorted and the function is supposed to return the index of the first element that is greater or equal to the key. They array is not large (below 200 elements) and will be prepared once for a large number of searches. Array elements after the n-th can if necessary be initialized to something appropriate, if that speeds up the search. No, binary search is not allowed, only linear search.

  • Problem with StandardOutput stream in async mode.

    - by JF
    Hi everyone. I have a program that launches command line processes in async mode, using BeginOutputReadLine. My problem is that the .Exited event is triggered when there is still some .OutputDataReceived events being triggered. What I do in my .Exited event must happen only once all my .OutputDataReceived events are done, or I'll be missing some output. I looked in the Process class to see if anything could be useful to me, as to wait for the stream to be empty, but all I find is for sync mode only. Can any of you help? Thanx.

  • Visual Studio 2010 shortcut to select word / expression / line / section / method?

    - by Lernkurve
    There is a shortcut Ctrl+Shift+W to select the entire word at the current cursor position. Is there a similar shortcut that keeps expanding the selected region every time I apply it? I mean, is there a shortcut which selects the word when applied once (same as Ctrl+Shift+W) and selects the entire line when applied twice in a row and selects the entire block when applied three times etc., i.e. keeps expanding the selected region step by step? I remember seeing such a shortcut, but I don't remember whether it was for Visual Studio or some other editor.

  • Weird IIS7 http redirection behavior

    - by wows
    I have a web server running Windows Server 2008 with IIS7. I have a bunch of websites which are all bound to the same IP address, but with different host header values. Most of the host headers are something like www.sitename.com. I also have a corresponding website entry for each which listens for the host "sitename.com" and does a redirect to "www.sitename.com" within IIS7 (to cater for non-www requests). Now this is all pretty straight forward, but I've noticed the when setting up the Http Redirection, some wierd things happen: Firstly, the "redirect" website entries must be pointed at a different physical directory than the site it's trying to redirect to, otherwise the redirection settings get set for both sites at once. Secondly, sometimes whilst setting up Http Redirection on an individual site, Http Redirection gets set at a server level, and all sites start redirecting to that one URL. How does this happen? Under what circumstances could setting Http Redirection on an individual site affect all sites? This is scary!!!

  • Joomla 1.5 Media Manager sets incorrect file permissions when uploading

    - by Scott Mayfield
    Howdy all, I have a Joomla 1.5 installation running on Windows Server 2008, installed via the Web Platform Installer. When uploading images with the media manager (native uploader, not the flash bulk uploader), the files arrive on the server correctly, but are given incorrect permissions. Specifically, the IIS_IUSRS group is not given access to the file. I might be incorrect about what group/user is SUPPOSED to get access to the files, but so far, I've found that unless I give IIS_IUSRS access to the uploaded files, they won't appear on the site or in the media manager (appear as broken images). Once I give IIS_IUSRS permission to the files, they work fine. So far, all the research I've done has led me to linux specific fixes that involve either changing the umask on the server, or directly modifying the Joomla codebase to add an appropriate chmod command to the upload process, but I really don't want to modify Joomla directly. I have to believe there's a setting here somewhere that will do the job, either on the Joomla or Windows side of the equation. Any thoughts? Scott

  • Hide Soft Keyboard Not Working ...

    - by stormin986
    I'm developing on the Droid Incredible (and have tested on a 1.5 AVD Emulator as well), and one of the tabs in my tab widget consists of a listview and a row with an EditText and a Send button (for a chat feature). I am using the following to close the soft keyboard once I click Send, but it's not working. This is identical to code I've found elsewhere that people have upvoted as correct. See anything I'm missing? // in Button's onClick(): EditText chatTextBox = (EditText) findViewById(R.id.chat_entry); // Handle button click ... chatTextBox.setText(""); InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE); imm.hideSoftInputFromInputMethod(chatTextBox.getWindowToken(), InputMethodManager.HIDE_IMPLICIT_ONLY); I also tried changing the flag to 0. No luck. Anyone know what's up??

  • Using TFSBuild to publish ClickOnce files that include prerequisites

    - by icancsharp
    I have declared an MSBuild tag in my TFSBuild project in order to publish ClickOnce files for my project. WSE 3.0 and .Net 3.0 are both pre-requisites for the application, so in Visual Studio I have ticked those as pre-requisites. When I build from Visual Studio, it creates a setup.exe file that I can publish to my web site. When you browse to this setup.exe file it installs WSE3.0 and .Net 3.0 and then continues to install my application, which works well. If I get TFS to create the click once files using the MSBuild tag in the TFSBuild file, it creates the setup.exe file, which I can publish to my website in the same way (along with all the other ClickOnce files). When I browse to setup.exe now, however, the prerequisites don't get installed and therefore my program does not run. Does anyone know how to get TFS to build a correct setup.exe file that properly bootstraps my prerequisites?

  • How to Save Hundreds or Thousands of Dollars on Cell Phone Service

    - by Chris Hoffman
    Cell phone contracts are bad. You get a seemingly cheap phone up front, but you more than pay for the cost of the phone over two years. Prepaid phone plans are surging in North America for a reason. Prepaid phone plans will be cheaper and more flexible than traditional contracts with big carriers for many people. However much you use your phone, there’s a good chance you can save money with a prepaid service. No More Contracts Here’s how cell phone service typically works in North America: You get a subsidized phone for “free”, $99, or $199. You sign up for a two-year contract and more than pay back the cost of that phone over the length of the contract. This is similar to leasing something or purchasing it on a credit card and paying it back over two years — you spend less up front, but you’re paying more in the long run. But this isn’t the only option. You could opt for a cheaper prepaid service that doesn’t lock you into a contract. If you don’t use your phone much, you could just pay for what you use and avoid the hefty cell phone bills. If you use your phone a lot, you could get a cheaper plan, too. Now, this certainly isn’t for everyone. If you want the latest iPhone or Galaxy smartphone every two years and require a 4G data connection, prepaid services may not be for you. On the other hand, if you don’t need the latest phone, you can save money here. You can also save a huge amount of money if you don’t use your phone much. Phone Options When you choose your prepaid or contract-free service, you’ll often be able to purchase a phone from them. You’ll generally be able to find dirt-cheap dumbphones and the cheapest, slowest Android phones for not very much money. If you are able to buy a top-of-the-line smartphone, you’ll have to pay the full, unsubsidized price. That’s $649 for either an iPhone 5S or Samsung Galaxy S4. Whatever phones the service provider offers, you could always buy a phone elsewhere — for example, you could buy an unsubsidized iPhone direct from Apple and then take it to your cell phone service of choice. Most services will allow you to get a SIM card and pop it into your existing phone rather than purchasing a phone. If you can get a hand-me-down smartphone, you can often save quite a bit of money. For example, you may have a family member upgrading from an iPhone 4S to an iPhone 5S. You could take their phone to a prepaid carrier and have a nicer phone on a cheap cell phone plan. If you brought an old smartphone to a big carrier like AT&T or Verizon, they wouldn’t give you a discount on your monthly plan. You’d have to pay the same amount of money every month as if you had gotten a subsidized phone. Google’s Nexus phones are also great options for people looking to buy smartphones and pay up-front. Google’s Nexus 4 offered a modern, almost top-of-the-line Android smartphone experience at $299 or $349 when it came out last year. Google will soon be releasing the Nexus 5 and it’s expected to be priced at $349. That’s certainly a lot more than a cheap phone, but it’s a fairly high-end smartphone at almost half the price of an iPhone 5S or Galaxy S4. Nexus phones can be purchased online from Google’s Play Store. Service Options When choosing a service, you need to consider what you actually use. If you’re someone who only uses your phone rarely, you can get plans that will allow you to pay as little as a few dollars per month. If you’re someone who’s usually in range of Wi-Fi, you may not need much data at all. If you want a plan with unlimited talk, texting, and data usage, you can get it for much cheaper than you’d pay on a major carrier like AT&T. The options here range from pay-as-you-go plans, like the ones offered by T-Mobile, which allow you to put a certain amount of money in and only drain that balance when you actually use minutes, texts, or data. If you only make a few calls and send a few texts per month, you’d only pay a few bucks. On the other end, Walmart’s Straight Talk service is a popular option that offers unlimited talk, texting, and data at $45 per month. Which service is right for you depends on a lot of things, including your usage and what each network’s coverage is like in your area. You’ll want to do some research of your own before choosing a service. Prepaid services also offer you even more flexibility after you choose one. If you’re not happy or a better deal comes along, you can switch — you’re not locked into your service for two years and you won’t pay an early termination fee.

  • Efficiently making web pages from multiple servers

    - by james.bcn
    I want to create a service that allows diverse web site owners to integrate material from my web servers into content served from their own servers. Ideally the resulting web page would only be delivered from the web site owners server, and the included content would be viewed as being part of the site by Google - which I think would rule out iframes or client-side Javascript to get the content from my server (although I may be wrong about that?). Also the data wouldn't actually be updated that often, say once a day, so it would be inefficient to get the data from my web servers with every request. Finally, the method needs to be as simple as possible so that it is easy for web site owners to integrate into their own sites. Are there any good methods for doing this sort of thing? If not then I guess the simple way is with iframes or Javascript.

  • SQLServer Replication, dealing with updating data in a subscriber without merging with the publisher

    - by FlySwat
    To simplify my problem, picture two databases, one is a publisher, one is a replicated subscriber. Most of the time, changes are configured in the publisher, and pushed to the subscriber once per day using transactional replication. (The subscriber is the main production database). However, on a rare occasion, we need to make a change directly to the subscriber database. This does not break replication, however to ensure consistency, we also want to replicate this single change back to the publisher database. My first thought was to make both databases publishers to each other, but that does not work. Merge replication also does not work as that merges the data together, and we really only want to push that single change from the subscriber back to the publisher. Is there some other replication scheme I can use here, or do I need to invent my own thing?

  • 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.

  • JTable.setRowHeight prevents me from adding more rows

    - by Brent Parker
    I'm working on a pretty simple Java app in order to learn more about JTables, TableModels, and custom cell renderers. The table is a simple table with 8 columns only with text in them. When you click on an "add" button, a dialog pops up and lets you enter the data for the columns. Now to my problem. One of the columns (the last one) should allow for multiple lines of text. I'm already putting HTML into the field, but it is not wrapping. I did some research and looked into JTable#setRowHeight(). However, once I use setRowHeight, I can no longer add rows to the table. The data is put into the table model, but it does not show in the table. If I remove the setRowHeight line, then it adds data just fine. Is there another step to adding data to my data model that I'm missing? Thanks a lot!

  • Does Eclipse has a plugin for code clips like in Coda?

    - by Sinan Y.
    There is a very useful "Clips" feature in Coda, do we have such thing in Eclipse? What it does is pretty simple, you save once a code clip which you use very often and assign it a shortcut and when you want to re-use it on editor you type the shortcut you assigned and it automatically pastes that code clip and sets caret position to the defined position. On the example here (second image) when i write 4dom and press TAB afterwards it types me this... jQuery(function($){ //puts cursor here }); Since it is a very useful feature i miss that one on Eclipse, is there a plugin for this? Thanks, Sinan.

  • Django : proper way to use model, duplicates!

    - by llazzaro
    Hello, I have a question about the proper, best way to manage the model. I am relative newbie to django, so I think I need to read more docs, tutorials,etc (suggestions for this would be cool!). Anyway, this is my question : I have a python web crawler, that is "connected" with django model. Crawling is done once a day, so its really common to find "duplicates". To avoid duplicates I do this : cars = Car.Objects.filter(name=crawledItem['name']) if len(cars) 0: #object already exists, update it car = cars[0] else: car = Car() #some non-relevant code here car.save() I want to know, if this is the proper/correct way to do it or its any "automatic" way to do it. Its possible to put the logic inside the Car() constructor also, should I do that? Thanks a lot!

  • Extending Database-as-a-Service to Provision Databases with Application Data

    - by Nilesh A
    Oracle Enterprise Manager 12c Database as a Service (DBaaS) empowers Self Service/SSA Users to rapidly spawn databases on demand in cloud. The configuration and structure of provisioned databases depends on respective service template selected by Self Service user while requesting for database. In EM12c, the DBaaS Self Service/SSA Administrator has the option of hosting various service templates in service catalog and based on underlying DBCA templates.Many times provisioned databases require production scale data either for UAT, testing or development purpose and managing DBCA templates with data can be unwieldy. So, we need to populate the database using post deployment script option and without any additional work for the SSA Users. The SSA Administrator can automate this task in few easy steps. For details on how to setup DBaaS Self Service Portal refer to the DBaaS CookbookIn this article, I will list steps required to enable EM 12c DBaaS to provision databases with application data in two distinct ways using: 1) Data pump 2) Transportable tablespaces (TTS). The steps listed below are just examples of how to extend EM 12c DBaaS and you can even have your own method plugged in part of post deployment script option. Using Data Pump to populate databases These are the steps to be followed to implement extending DBaaS using Data Pump methodolgy: Production DBA should run data pump export on the production database and make the dump file available to all the servers participating in the database zone [sample shown in Fig.1] -- Full exportexpdp FULL=y DUMPFILE=data_pump_dir:dpfull1%U.dmp, data_pump_dir:dpfull2%U.dmp PARALLEL=4 LOGFILE=data_pump_dir:dpexpfull.log JOB_NAME=dpexpfull Figure-1:  Full export of database using data pump Create a post deployment SQL script [sample shown in Fig. 2] and this script can either be uploaded into the software library by SSA Administrator or made available on a shared location accessible from servers where databases are likely to be provisioned Normal 0 -- Full importdeclare    h1   NUMBER;begin-- Creating the directory object where source database dump is backed up.    execute immediate 'create directory DEST_LOC as''/scratch/nagrawal/OracleHomes/oradata/INITCHNG/datafile''';-- Running import    h1 := dbms_datapump.open (operation => 'IMPORT', job_mode => 'FULL', job_name => 'DB_IMPORT10');    dbms_datapump.set_parallel(handle => h1, degree => 1);    dbms_datapump.add_file(handle => h1, filename => 'IMP_GRIDDB_FULL.LOG', directory => 'DATA_PUMP_DIR', filetype => 3);    dbms_datapump.add_file(handle => h1, filename => 'EXP_GRIDDB_FULL_%U.DMP', directory => 'DEST_LOC', filetype => 1);    dbms_datapump.start_job(handle => h1);    dbms_datapump.detach(handle => h1);end;/ Figure-2: Importing using data pump pl/sql procedures Using DBCA, create a template for the production database – include all the init.ora parameters, tablespaces, datafiles & their sizes SSA Administrator should customize “Create Database Deployment Procedure” and provide DBCA template created in the previous step. In “Additional Configuration Options” step of Customize “Create Database Deployment Procedure” flow, provide the name of the SQL script in the Custom Script section and lock the input (shown in Fig. 3). Continue saving the deployment procedure. Figure-3: Using Custom script option for calling Import SQL Now, an SSA user can login to Self Service Portal and use the flow to provision a database that will also  populate the data using the post deployment step. Using Transportable tablespaces to populate databases Copy of all user/application tablespaces will enable this method of populating databases. These are the required steps to extend DBaaS using transportable tablespaces: Production DBA needs to create a backup of tablespaces. Datafiles may need conversion [such as from Big Endian to Little Endian or vice versa] based on the platform of production and destination where DBaaS created the test database. Here is sample backup script shows how to find out if any conversion is required, describes the steps required to convert datafiles and backup tablespace. SSA Administrator should copy the database (tablespaces) backup datafiles and export dumps to the backup location accessible from the hosts participating in the database zone(s). Create a post deployment SQL script and this script can either be uploaded into the software library by SSA Administrator or made available on a shared location accessible from servers where databases are likely to be provisioned. Here is sample post deployment SQL script using transportable tablespaces. Using DBCA, create a template for the production database – all the init.ora parameters should be included. NOTE: DO NOT choose to bring tablespace data into this template as they will be created SSA Administrator should customize “Create Database Deployment Procedure” and provide DBCA template created in the previous step. In the “Additional Configuration Options” step of the flow, provide the name of the SQL script in the Custom Script section and lock the input. Continue saving the deployment procedure. Now, an SSA user can login to Self Service Portal and use the flow to provision a database that will also populate the data using the post deployment step.
