  • How to add text to path?

    - by Pritorian
    Hi all. Te question is how to add text to path element. For example, I have path: Path firstPath = new Path(); firstPath.Stroke = Brushes.Black; firstPath.StrokeThickness = 1; myCanvas.Children.Add(firstPath); LineGeometry firstLine = new LineGeometry(); firstPath.Data = firstLine; And somewhere I define line's Start and End point's. The path is binded to controls (for example - two ellipses) and when I drag one of them, the line is dynamically resized and moved to be pinned to both objects. And now I wand to add some text, that would fit to this line and follow it. Any recommendations how to do this?

  • uniform generation of points on 3D box

    - by Myx
    Hello: I would like to generate random points on a 3D box defined by its (minx, miny, minz) and (maxx, maxy, maxz) corners. I was thinking of generating a random point inside of the box and then somehow projecting it onto one of the box sides. However, I don't have explicit plane information for the box sides and this seems like it will not produce a uniform distribution of points since if some sides of the box are bigger than others, those sides should have more points generated on them. Any suggestions are appreciated. Thanks.

  • Design of Business Layer

    - by Adil Mughal
    Hi, We are currently revamping our architecture and design of application. We have just completed design of Data Access Layer which is generic in the sense that it works using XML and reflection to persist data. Any ways now we are in the phase of designing business layer. We have read some books related to Enterprise Architecture and Design so we have found that there are few patterns that can be applied on business layer. Table Pattern and Domain Model are example of such patterns. Also we have found Domain Driven Design as well. Earlier we decided to build Entities against table objects. But we found that there is difference in Entities and Value Objects when it comes to DDD. For those of you who have gone through such design. Please guide me related to pattern, practice and sample. Thank you in advance! Also please feel free to discuss if you didn't get any point of mine.

  • Newbie: UINavigationController is pulling me back from further learning :(

    - by nithin
    I have created a window-based application and my problem is I am unable to create UINavigationController on the go. InFact I don't know how to do that. My AppDelegeate - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after application launch [window addSubview:logInView.view]; [window makeKeyAndVisible]; } here the logInView is an object of @interface LogInViewController : UIViewController { IBOutlet UITextField *usernameField; IBOutlet UITextField *passwordField; IBOutlet UIButton *logInButton; } -(IBAction) logInClick:(id) sender; from the click action of this loginviewcontroller It should be showing the home screen with navigation controller. and I have to add many subviews. My question is where should I init the UINavigationController and where could I write the codes for adding subviews? how to map it with interfacebuilder?

  • FIPS-compliant encryption in .NET 2.0

    - by Odrade
    We have a .NET 2.0 application that uses the RijindaelManaged class to encrypt some sensitive data. This was fine until we ran into some machines that require the use of FIPS-compliant algorithms. We'd like to switch to AesCryptoServiceProvider, but most of our target machines haven't upgraded past .NET 2.0. Requiring an upgrade is out of the question. After all, upgrades are scary! Is there any way we could use AesCryptoServiceProvider in a .NET 2.0 application? Since 3.5 uses the 2.0 CLR, I was hoping there might be a way to build the needed libraries into the app. Failing that, could someone point me to a reference on the native API that's wrapped by AesCryptoServiceProvider?

  • Xerces SAX parser ignore the xmlxs:xsi attribute as an attribute of an element

    - by user603301
    Hi, Using Xerces SAX parser I try to retrieve all elements and their attributes of this XML file: -------------- Begin XML file to parse ---------------- <?xml version="1.0" encoding="UTF-8"?> <invoice xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="my.xsd"> <parties> (...) -------------- End XML file to parse ---------------- When getting the attributes for the element 'invoice', Xerces++ does not insert the 'xmlns:xsi' attribute in the list of 'Attributes' for the element 'invoice'. However, the attribute 'xsi:noNamespaceSchemaLocation' is inserted in the list. Why? Is there a specific reason from an XML standard point of view ? Is there a way to configure Xerces++ SAX parser so that it inserts this attribute as well? (The documentation on setting the parser properties does not tell how). Thanks for your help.

  • Problem with Qt::QueuedConnection, signal delivered after disconnect

    - by lutku
    Hi, I just discovered interesting behavior of queued connection in Qt 4.6: First queued connection is made: connect(someSender, SIGNAL(completed()), this, SLOT(handleCompletion()), Qt::QueuedConnection) Then someSender sends the signal: emit completed() Before receiving signal (as it is in queue), I disconnect from the signal: disconnect(someSender, SIGNAL(completed()), this, SLOT(handleCompletion()) Still, handleCompletion slot is invoked at next eventloop iteration. I can prevent this from happening by using someSender-blockSignals(true) at correct point, but it feels awful not to mention having some boolean flag to disable slot's functionality. Especially, I feel amazed that this behavior is not mentioned in Qt documentation (at least I haven't found). Finally the question: any sensible way to avoid this from happening?

  • Flex Force Decimal

    - by babyangel86
    Hi, I'm looking for a regex or a way to format the NumberValidator so that only decimal places are allowed. The domain="real" allows you to put integer values, but I need to force the user to but in 2.0 if they want an integer. This is because they pass through a Castor mapping file, it complains if it gets an integer when it expects a decimal. I dont want to restrict the number of decimal places, just insist that there must be a point, and a number after it. Any help would be much appreciated.

  • Unit Test to Run .sql script to SQL Create Database

    - by Lee Englestone
    Can anyone point me in the direction of how I could get a NUnit test to run a .sql file to Create / Setup a database. I know about the the TestFixtureSetUp and TestFixtureTearDown attributes / methods in NUnit. So I KNOW how to call methods before and after all or each unit tests. I'm just unsure of how to load and execute the contents of a .sql file agains a SQL Server 2005 database programatically. Any examples? This is part of our TDD / CI. We are wanting to create the database before and tear down the database after executing unit tests. Cheers, -- Lee

  • How to create program that can be run by: #service myservice start

    - by Saif Bechan
    I am new to Linux and want to know what kind of programs can be run by using. #service myservice start And the programs stays on until stopped. Are they normal c++ programs or are they different. In some tutorials i have seen that they use ./myprogram to start a program. Another thing I have seen is the usage of .sh files. One last type of program i see is executed by the command: #/usr/bin/myprogramm Can someone explain the difference between these or point me to a basic tutorial/guide.

  • The difference between traditional DLL and COM DLL.

    - by smwikipedia
    I am currently studying COM. I found that COM DLL is kind of built upon the traditional DLL infrastructure. When we build COM DLLs, we still rely on the traditional DLL export methods to lead us to the internal COM co-classes. If COM is for component reusing at the binary level, I think the traditional DLL can achieve the same thing. They both expose functions, they are both binary, so what's the point of turning to COM approach? Currently, I have the feeling that the traditional DLL expose methods in a "flat" manner, while the COM DLL expose methods in an "OOP" hierarchy manner. And the OOP manner seems to be a better approach. Could this be the reason why COM prevails? Many thanks.

  • Creating a customized video using Flash and XML

    - by Aaron Ladage
    The problem: I have to create a Flash video (in CS3) that will query a MySQL database and display that data at certain points in the video. The bigger problem: I'm not a Flash/ActionScript developer, so this is all very foreign to me! I've divided this project into two parts: a.) dynamically generate an XML feed from the data using PHP (using an ID number passed in the URL's query string), and b.) be able to work with it in Flash. I've got the first part working, but am pretty lost in Flash. I can parse the XML, but I'm not sure how to set the data up as variables and attach it to a video's cue points. Can anyone point me in the direction of a good tutorial or offer some advice?

  • 5 Best Practices - Laying the Foundation for WebCenter Projects

    - by Kellsey Ruppel
    Today’s guest post comes from Oracle WebCenter expert John Brunswick. John specializes in enterprise portal and content management solutions and actively contributes to the enterprise software business community and has authored a series of articles about optimal business involvement in portal, business process management and SOA development, examining ways of helping organizations move away from monolithic application development. We’re happy to have John join us today! Maximizing success with Oracle WebCenter portal requires a strategic understanding of Oracle WebCenter capabilities.  The following best practices enable the creation of portal solutions with minimal resource overhead, while offering the greatest flexibility for progressive elaboration. They are inherently project agnostic, enabling a strong foundation for future growth and an expedient return on your investment in the platform.  If you are able to embrace even only a few of these practices, you will materially improve your deployment capability with WebCenter. 1. Segment Duties Around 3Cs - Content, Collaboration and Contextual Data "Agility" is one of the most common business benefits touted by modern web platforms.  It sounds good - who doesn't want to be Agile, right?  How exactly IT organizations go about supplying agility to their business counterparts often lacks definition - hamstrung by ambiguity. Ultimately, businesses want to benefit from reduced development time to deliver a solution to a particular constituent, which is augmented by as much self-service as possible to develop and manage the solution directly. All done in the absence of direct IT involvement. With Oracle WebCenter's depth in the areas of content management, pallet of native collaborative services, enterprise mashup capability and delegated administration, it is very possible to execute on this business vision at a technical level. To realize the benefits of the platform depth we can think of Oracle WebCenter's segmentation of duties along the lines of the 3 Cs - Content, Collaboration and Contextual Data.  All three of which can have their foundations developed by IT, then provisioned to the business on a per role basis. Content – Oracle WebCenter benefits from an extremely mature content repository.  Work flow, audit, notification, office integration and conversion capabilities for documents (HTML & PDF) make this a haven for business users to take control of content within external and internal portals, custom applications and web sites.  When deploying WebCenter portal take time to think of areas in which IT can provide the "harness" for content to reside, then allow the business to manage any content items within the site, using the content foundation to ensure compliance with business rules and process.  This frees IT to work on more mission critical challenges and allows the business to respond in short order to emerging market needs. Collaboration – Native collaborative services and WebCenter spaces are a perfect match for business users who are looking to enable document sharing, discussions and social networking.  The ability to deploy the services is granular and on the basis of roles scoped to given areas of the system - much like the first C “content”.  This enables business analysts to design the roles required and IT to provision with peace of mind that users leveraging the collaborative services are only able to do so in explicitly designated areas of a site. Bottom line - business will not need to wait for IT, but cannot go outside of the scope that has been defined based on their roles. Contextual Data – Collaborative capabilities are most powerful when included within the context of business data.  The ability to supply business users with decision shaping data that they can include in various parts of a portal or portals, just as they would with content items, is one of the most powerful aspects of Oracle WebCenter.  Imagine a discussion about new store selection for a retail chain that re-purposes existing information from business intelligence services about various potential locations and or custom backend systems - presenting it directly in the context of the discussion.  If there are some data sources that are preexisting in your enterprise take a look at how they can be made into discrete offerings within the portal, then scoped to given business user roles for inclusion within collaborative activities. 2. Think Generically, Execute Specifically Constructs.  Anyone who has spent much time around me knows that I am obsessed with this word.  Why? Because Constructs offer immense power - more than APIs, Web Services or other technical capability. Constructs offer organizations the ability to leverage a platform's native characteristics to offer substantial business functionality - without writing code.  This concept becomes more powerful with the additional understanding of the concepts from the platform that an organization learns over time.  Let's take a look at an example of where an Oracle WebCenter construct can substantially reduce the time to get a subscription-based site out the door and into the hands of the end consumer. Imagine a site that allows members to subscribe to specific disciplines to access information and application data around that various discipline.  A space is a collection of secured pages within Oracle WebCenter.  Spaces are not only secured, but also default content stored within it to be scoped automatically to that space. Taking this a step further, Oracle WebCenter’s Activity Stream surfaces events, discussions and other activities that are scoped to the given user on the basis of their space affiliations.  In order to have a portal that would allow users to "subscribe" to information around various disciplines - spaces could be used out of the box to achieve this capability and without using any APIs or low level technical work to achieve this. 3. Make Governance Work for You Imagine driving down the street without the painted lines on the road.  The rules of the road are so ingrained in our minds, we often do not think about the process, but seemingly mundane lane markers are critical enablers. Lane markers allow us to travel at speeds that would be impossible if not for the agreed upon direction of flow. Additionally and more importantly, it allows people to act autonomously - going where they please at any given time. The return on the investment for mobility is high enough for people to buy into globally agreed up governance processes. In Oracle WebCenter we can use similar enablers to lane markers.  Our goal should be to enable the flow of information and provide end users with the ability to arrive at business solutions as needed, not on the basis of cumbersome processes that cannot meet the business needs in a timely fashion. How do we do this? Just as with "Segmentation of Duties" Oracle WebCenter technologies offer the opportunity to compartmentalize various business initiatives from each other within the system due to constructs and security that are available to use within the platform. For instance, when a WebCenter space is created, any content added within that space by default will be secured to that particular space and inherits meta data that is associated with a folder created for the space. Oracle WebCenter content uses meta data to support a broad range of rich ECM functionality and can automatically impart retention, workflow and other policies automatically on the basis of what has been defaulted for that space. Depending on your business needs, this paradigm will also extend to sub sections of a space, offering some interesting possibilities to enable automated management around content. An example may be press releases within a particular area of an extranet that require a five year retention period and need to the reviewed by marketing and legal before release.  The underlying content system will transparently take care of this process on the basis of the above rules, enabling peace of mind over unstructured data - which could otherwise become overwhelming. 4. Make Your First Project Your Second Imagine if Michael Phelps was competing in a swimming championship, but told right before his race that he had to use a brand new stroke.  There is no doubt that Michael is an outstanding swimmer, but chances are that he would like to have some time to get acquainted with the new stroke. New technologies should not be treated any differently.  Before jumping into the deep end it helps to take time to get to know the new approach - even though you may have been swimming thousands of times before. To quickly get a handle on Oracle WebCenter capabilities it can be helpful to deploy a sandbox for the team to use to share project documents, discussions and announcements in an effort to help the actual deployment get under way, while increasing everyone’s knowledge of the platform and its functionality that may be helpful down the road. Oracle Technology Network has made a pre-configured virtual machine available for download that can be a great starting point for this exercise. 5. Get to Know the Community If you are reading this blog post you have most certainly faced a software decision or challenge that was solved on the basis of a small piece of missing critical information - which took substantial research to discover.  Chances were also good that somewhere, someone had already come across this information and would have been excited to share it. There is no denying the power of passionate, connected users, sharing key tips around technology.  The Oracle WebCenter brand has a rich heritage that includes industry-leading technology and practitioners.  With the new Oracle WebCenter brand, opportunities to connect with these experts has become easier. Oracle WebCenter Blog Oracle Social Enterprise LinkedIn WebCenter Group Oracle WebCenter Twitter Oracle WebCenter Facebook Oracle User Groups Additionally, there are various Oracle WebCenter related blogs by an excellent grouping of services partners.

  • SetSel on EN_SETFOCUS or WM_SETFOCUS doesn't work

    - by Coder
    I've ran into next mystic thing in Winapi/MFC, I have an edit box, contents of which I have to select on Tab, Lclick, Rclick, Mclick and so on. The sort of obvious path is to handle the SETFOCUS message and call SetSel(0, -1), which should select all text. But it doesn't work! What's wrong? I tried googling, everyone seems to override Lclilks or handle SetSel in parent windows, but this is wrong from encapsulation point of view, also multiple clicks (user wants to insert something in the middle of the text) will break, and so on. Why isn't my approach working, I tried like 10 different ways, tried to trap all possible focus messages, looked up info on MSDN, but nothing works as expected. Also, I need to recreate the carret on focus, which also doesn't seem to work. SETFOCUS message gets trapped alright. If I add __asm int 3, it breaks every time. It's the create carret and setsel that gets swallowed it seems.

  • Is it a good idea to cache data from web services into a database?

    - by Thierry Lam
    Let's assume that Stackoverflow offers web services where you can retrieve all the questions asked by a specific user. A request to get all question from user A can result in the following json output: { { "question": "What is rest?", "date_created": "20/02/2010", "votes": 1, }, { "question": "Which database to use for ...", "date_created": "20/07/2009", "votes": 5, }, } If I want to manipulate and present the data in any ways that I want, will it be wise to dump it in a local database? At some point, I will also want to retrieve all answers for each question and store them in a local database. The workflow that I'm thinking is: User logs in. Web services retrieve all questions asked by the logged in user, dump them in a local database. User wants all answers for a specific question, another web service does the retrieval and dump them in a local database. After user logs out, delete from the local database all questions and answers from that user.

  • Foreign keys in MySQL?

    - by icco
    I have been slowly learning SQL the last few weeks. I've picked up all of the relational algebra and the basics of how relational databases work. What I'm trying to do now is learn how it's implemented. A stumbling block I've come across in this, is foreign keys in MySQL. I can't seem to find much about the other than that they exist in the InnoDB storage schema that MySQL has. What is a simple example of foreign keys implemented in MySQL? Here's part of a schema I wrote that doesn't seem to be working if you would rather point out my flaw than show me a working example. CREATE TABLE `posts` ( `pID` bigint(20) NOT NULL auto_increment, `content` text NOT NULL, `time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP, `uID` bigint(20) NOT NULL, `wikiptr` bigint(20) default NULL, `cID` bigint(20) NOT NULL, PRIMARY KEY (`pID`), Foreign Key(`cID`) references categories, Foreign Key(`uID`) references users ) ENGINE=InnoDB;

  • [AS2] Use for variable as parameter and keep it different for each iteration

    Hello, I have a basic for loop to loop through buttons and set some stuff and onPress handlers: for (i=1;i<=20;i++){ //do some stuff _root["button"+i].onPress = function(){ someMC.gotoAndStop(i+1); } } However, as I noticed, all buttonsthen link to one and same frame - all point to last i + 1 - Is there any possibility to call gotoAndStop with "static" Number, so in next iteration, it won't change? Edit: Ex. for last statement: Iteration 5 will call gAS /*gotoAndStop:]*/(6); Iteration 6 -> gAS(7); Iteration 7 -> gAS(8);

  • Why does UIImageView "darken"/saturate PNG images, and can I stop it?

    - by Ben
    I have a PNG file in a UIImageView, and next to that I have an EAGLView which displays the continuation of that same image (long story) as a texture, carved from the same original PNG. The point is, that these images, which should match up flawlessly, actually have somewhat differing color saturation. Normally I'd blame my handling of the PNG texture load in GL, but when I hold Preview (with the PNG) up to the iPhone simulator, it's GL that's spot on, and the UIImageView that's wrong! It's taken the image and made it ever-so-slightly more saturated. The image view is opaque with 100% alpha. I verified this on a clean UIImageView with another PNG file when put next to Preview. Anyone know what's up?

  • Uncompressing zlib data using boost::iostreams::filtering_streambuf trouble

    - by GuitaringEgg
    I'm trying to write a small class that will load the chunk data from part of a minecraft world file. I'm to the point where I have stored some data in a char array which was compressed with zlib and need to decompress it. I'm trying to use the boost filtering_streambuf to do this. char * rawChunk = new char[length - 1]; // Load chunk data stringstream ssRawChunk(rawChunk); boost::iostreams::filtering_istream in; in.push(boost::iostreams::zlib_decompressor()); in.push(ssRawChunk); stringstream ssOut; boost::iostreams::copy(in, ssOut); My problem is that rawChunk contains null data, so when coping data from (char*) rawChunk to (stringstream) ssRawChunk, it terminates at ~257 instead of the expected length 2154. Is there any way to use filtering_streambuf without stringstream to allow for null data or is there a way to stop stringstream to not terminate on null data?

  • Efficient way to calculate byte length of a character, depending on the encoding

    - by BalusC
    What's the most efficient way to calculate the byte length of a character, taking the character encoding into account? In UTF-8 for example the characters have a variable byte length, so each character needs to be determined individually. As far now I've come up with this: char c = getItSomehow(); String encoding = "UTF-8"; int length = new String(new char[] { c }).getBytes(encoding).length; But this is clumsy and inefficient in a loop since a new String needs to be created everytime. I can't find other and more efficient ways in the Java API. I imagine that this can be done with bitwise operations like bit shifting, but that's my weak point and I'm unsure how to take the encoding into account here :) If you question the need for this, check this topic.

  • git- how to troubleshoot "cannot find command"

    - by Frank Schwieterman
    I need help getting git extensions to run with msysgit. I have had bad luck with extensions git-tfs and git-fetchall, in both cases it is the same problem. The addon will require a file to be placed where git can find it (git-tfs.exe and git-fetchall.sh). I understand this to mean the files need to be in a directory that is in the 'PATH' environment variable. In both cases I get stuck at this point: $ git-diffall bash: git-diffall: command not found When I run echo %PATH% from a regular command shell, it shows my path variable includes the directories where git-diffall and git-tfs are. How can I debug this, or am I missing something? Is there a way within msysgit to verify the command search path is what I expect?

  • FileInputStream negative skip

    - by Peter Štibraný
    I'm trying to find more about history of FileInputStream.skip(negative) operation. According to InputStream documentation: If n is negative, no bytes are skipped. It seems that implementation of FileInputStream from Sun used to throw IOException instead, which is now also documented in Javadoc: If n is negative, an IOException is thrown, even though the skip method of the InputStream superclass does nothing in this case. I just tried that, and found that FileInputStream.skip(-10) did in fact return -10! It didn't threw exception, it didn't even return 0, it returned -10. (I've tried with Java 1.5.0_22 from Sun, and Java 1.6.0_18 from Sun). Is this a known bug? Why hasn't it been fixed, or why documentation is kept the way it is? Can someone point me to some discussion about this issue? I can't find anything.
