  • WCF + NserviceBus Names notation

    - by John
    Hi. I trying to create WCF via NserviceBus. Create contract: [ServiceContract] public interface INotifyBusService { [OperationContract(Action = "http://tempuri.org/IWcfServiceOf_RequestMessage_ResultType/Process", ReplyAction = "http://tempuri.org/IWcfServiceOf_RequestMessage_ResultType/ProcessResponse")] ResultType Notify(RequestMessage request); } The problem: When i create a clinet it can't handle this service because expected node with name "Process" in "http://tempuri.org/" namespace. if I do like that [OperationContract(Name = "Process", Action = "http://tempuri.org/IWcfServiceOf_RequestMessage_ResultType/Process", ReplyAction = "http://tempuri.org/IWcfServiceOf_RequestMessage_ResultType/ProcessResponse")] ResultType Notify(RequestMessage request); Everything works fine. Name = "Process" - it's a NServiceBus hardcode, like Enum return type in service method ?

  • SQL developer here -- Nesting with select * finicky in Oracle 10g?

    - by John Sullivan
    I am writing a simple diagnostic query I will execute in my Oracle 10g scratchpad. I am trying to do this as part of a step to build the query. In the SQL Scratchpad for Oracle 10g Enterprise Manager Console, this statement runs fine. SELECT * FROM v$session sess, v$sql sql WHERE sql.sql_id(+) = sess.sql_id and sql.sql_text <> ' ' If I try to wrap that up in Select * from () tb2 I get an error, "ORA-00918: Column Ambiguously Defined". I didn't think that could ever happen with this kind of statement so I am a bit confused. select * from (SELECT * FROM v$session sess, v$sql sql WHERE sql.sql_id(+) = sess.sql_id and sql.sql_text <> ' ') tb2 You should always be able to select * from the result set of another select * statement using this structure as far as I'm aware... right? Is Oracle/10g/the scratchpad trying to force me to accept a certain syntactic structure to prevent excessive nesting? Is this a bug in scratchpad or something about how oracle works?

  • How to enforce a 5-minute per post rule in a session object in Java?

    - by John
    I'm trying to figure out how to enforce a 5 minute per post/action rule. I'm developing a web application with Wicket in Java and I've got a session class which I was planning on using to keep track of these timers on a per-user basis. I wasn't planning on storing the timestamp in a database. public boolean isAllowedToPost() { if(null OR has 5 minutes passed since last post) { // set the new timestamp return true; } else { return false; } }

    I have a SurfaceView and I want the Bitmap Logo inside it in the canvas to be movable What I'm doing wrong ? static float x, y; Bitmap logo; SurfaceView ss = (SurfaceView) findViewById(R.id.svSS); logo = BitmapFactory.decodeResource(getResources(), R.drawable.logo); x = 40; y = 415; ss.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent me) { try { Thread.sleep(50); } catch (InterruptedException e) { e.printStackTrace(); } switch(me.getAction()) { case MotionEvent.ACTION_DOWN: x = me.getX(); y = me.getY(); break; case MotionEvent.ACTION_UP: x = me.getX(); y = me.getY(); break; case MotionEvent.ACTION_MOVE: x = me.getX(); y = me.getY(); break; } return true; } }); public class OurView extends SurfaceView implements Runnable{ Thread t = null; SurfaceHolder holder; boolean isItOK = false; public OurView(Context context) { super(context); holder = getHolder(); } public void run (){ while (isItOK == true){ //canvas DRAWING if (!holder.getSurface().isValid()){ continue; } Canvas c = holder.lockCanvas(); c.drawARGB(255, 200, 100, 100); c.drawBitmap(logo, x,y,null); holder.unlockCanvasAndPost(c); } } public void pause(){ isItOK = false; while(true){ try { t.join(); } catch (InterruptedException e) { e.printStackTrace(); } break; } t = null; } public void resume(){ isItOK = true; t = new Thread(this); t.start(); } } Now the surface view is just black .. nothing happens also its not colored 200, 100, 100

  • Ruby - Writing Hpricot data to a file

    - by John
    Hey everyone, I am currently doing some XML parsing and I've chosen to use Hpricot because of it's ease of use and syntax, however I am running into some problems. I need to write a piece of XML data that I have found out to another file. However, when I do this the format is not preserved. For example, if the content should look like this: <dict> <key>item1</key><value>12345</value> <key>item2</key><value>67890</value> <key>item3</key><value>23456</value> </dict> And assuming that there are many entries like this in the document. I am iterating through the 'dict' items by using hpricot_element = Hpricot(xml_document_body) f = File.new('some_new_file.xml') (hpricot_element/:dict).each { |dict| f.write( dict.to_original_html ) } After using the above code, I would expect that the output look like the following exactly like the XML shown above. However to my surprise, the output of the file looks more like this: <dict>\n", " <key>item1</key><value>12345</value>\n", " <key>item2</key><value>67890</value>\n", " <key>item3</key><value>23456</value\n", " </dict> I've tried splitting at the "\n" characters and writing to the file one line at a time, but that didn't seem to work either as it did not recognize the "\n" characters. Any help is greatly appreciated. It might be a very simple solution, but I am having troubling finding it. Thanks!

  • Java: pass an event to another component

    - by John
    Sorry I don't know if this is very clear, but I'm pretty new to Java. So I have a JFrame with a BorderLayout containing a JPanel and a JButton. What I want to do is when something happens in my JPanel, I want for example change the text of the JButton, or enable/disable it. How would I do that? How can I access the JButton from the JPanel? I know some ways of doing it but I don't think they're the best way to do it. What would be the best way to do this? Thanks in advance

  • VB.NET FileSystemWatcher Multiple Change Events

    - by John
    Hi. I have the following code: Imports System.IO Public Class Blah Public Sub New() InitializeComponent() Dim watcher As New FileSystemWatcher("C:\") watcher.EnableRaisingEvents = True AddHandler watcher.Changed, AddressOf watcher_Changed End Sub Private Sub watcher_Changed(ByVal sender As Object, ByVal e As FileSystemEventArgs) MsgBox(e.FullPath) End Sub End Class When I run it and save changes to a file on my C drive, the code works great, except it executes the watcher_Changed() method four times. Any idea why? The changeType is "4" every time. Thanks.

  • C++ - Print Out Objects From Set

    - by John Smith
    If I have a C++ set, declaration set personList; with iterator, set::const_iterator location; how can I print out the contents of the set? They are all person objects, and I have overridden the operator<< for Person. The line that errors is: cout << location and it's in a basic for loop. Netbeans gives the following error: proj.cpp:78: error: no match for ‘operator<<’ in ‘std::cout << location’ so it looks like it wants an override for the iterator's <<. Basically, I am taking objects that used to be stored in an array format, but are now in a set. What is the equivalent to cout << array[i] for sets?

  • [Visual C++]Forcing memory alignment of variables/data-structures

    - by John
    I'm looking at using SSE and I gather aligning data on 16byte boundaries is recommended. There are two cases to consider: float data[4]; struct myystruct { float x,y,z,w; }; I'm not sure the first case can be done explicitly, though there's perhaps a compiler option I could use? In the second case I remember being able to control packing in old versions of GCC several years back, is this still possible?

  • how to define div or table cell height depending on the height of other divs or cells

    - by John
    I want to have a web page that contains 3 parts: A header at the top of the page , a footer (both of which having specific height in px)and the main part of the page which should be a div or table cell with the appropriate height attribute in order to take all the available space between them. I want the page to take 100% of the browser window height, trying to avoid scrollbars. The problems I have are the following: USING DIVs a) If I set the maindiv height to 100%, the page overflows and I get a vertical scrolbar. (the maindiv's height is set to the 100% of the browser window) <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <style type="text/css"> <!-- body, html{ height: 100%; max-height:100%; width: 100%; margin:0; padding:0; } div{padding:0;margin:0;} #containerdiv{height:100%;width:100%;background-color:#FF9;border:0;} #headerdiv{height:150px;width:100%;background-color:#0F0;border:0;} #footerdiv{height:50px;width:100%;background-color:#00F;border:0; } #maindiv{ background-color:#F00; height:100%; } div{border:#000 medium solid;border:0;} </style> <body> <div id="containerdiv"> <div id="headerdiv">headerdiv</div> <div id="maindiv">maindiv</div> <div id="footerdiv">footerdiv</div> </div> </body> </html> b) If I set the maindiv height to auto, the maindiv height is depending on it's content, which is not what I want. USING tables a) If I set the main cell height to 100% it works fine with Firefox but in Internet Explorer 8 I get a vertical scrollbar (you can use the next code block using th style="height:100%" instead of "auto" to see this.) b) If I set the main cell to auto it seems to be working both in IE and FF but then I have the problem that anything I put inside the maincell (table or div) cannot get maincell's full height in IE. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <style type="text/css"> <!-- body, html, table{ height: 100%; width: 100%; margin:0; padding:0; } table{border:#000 0px solid} </style> <body> <table style="background:#063" cellpadding="0" cellspacing="0" border="0"> <tr><th style="height:150px;background-color:#FF0"></th></tr> <tr> <th style="height:auto"><table style="background:#0FF;" cellpadding="0" cellspacing="0" border="0"><tr><th style="height:auto">nested cell</th></tr></table> </th> </tr> <tr><th style="height:50px;background-color:#FF0"></th></tr> </table> </body> </html> </html> Any ideas? Maybe there is an easier way to define the size of the main part of the page in px using javascript? (my javascript skills are pretty poor so any help with this is welcome!)

  • Can a custom MFC window/dialog be a template class?

    - by John
    There's a bunch of special macros that MFC uses when creating dialogs, and in my quick tests I'm getting weird errors trying to compile a template dialog class. Is this likely to be a big pain to achieve? Here's what I tried: MyDlg.h template <class W> class CMyDlg : public CDialog { typedef CDialog super; DECLARE_DYNAMIC(CMyDlg <W>) public: CMyDlg (CWnd* pParent); // standard constructor virtual ~CMyDlg (); // Dialog Data enum { IDD = IDD_MYDLG }; protected: virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support DECLARE_MESSAGE_MAP() private: W *m_pWidget; //W will always be a CDialog }; IMPLEMENT_DYNAMIC(CMyDlg<W>, super) <------------------- template <class W> CMyDlg<W>::CMyDlg(CWnd* pParent) : super(CMyDlg::IDD, pParent) { m_pWidget = new W(this); } I get a whole bunch of errors but main one appears to be: error C2955: 'CMyDlg' : use of class template requires template argument list I tried using some specialised template versions of macros but it doesn't help much, other errors change but this one remains. Note my code is all in one file, since C++ templates don't like .h/.cpp like normal.

  • Hudson - Maven is failing (cannot create /dev/null/.m2) on Tomcat-6 - Gentoo

    - by John
    Hi there. I'm having major issues with getting Hudson up and running on a gentoo server with Tomcat 6. I'm able to deploy Hudson just fine, and I can browse the web-application, configure it and set up builds etc. However, when I try to run a build (in example "clean test" on a Maven2 project) I get this error ERROR: Failed to create /dev/null/.m2 I've google'd and for some it seems to be helping to put -DHUDSON_HOME=/home/hudson and -DMAVEN_HOME=/home/hudson in /etc/init.d/tomcat-6's JAVA_OPTS. However, I've tried that and by doing the same in /etc/conf.d/tomcat-6 , but I'm still getting this error. Has any of you had to deal with this before?

  • Better code for accessing fields in a matlab structure array?

    - by John
    I have a matlab structure array Modles1 of size (1x180) that has fields a, b, c, ..., z. I want to understand how many distinct values there are in each of the fields. i.e. max(grp2idx([foo(:).a])) The above works if the field a is a double. {foo(:).a} needs to be used in the case where the field a is a string/char. Here's my current code for doing this. I hate having to use the eval, and what is essentially a switch statement. Is there a better way? names = fieldnames(Models1); for ix = 1 : numel(names) className = eval(['class(Models1(1).',names{ix},')']); if strcmp('double', className) || strcmp('logical',className) eval([' values = [Models1(:).',names{ix},'];']); elseif strcmp('char', className) eval([' values = {Models1(:).',names{ix},'};']); else disp(['Unrecognized class: ', className]); end % this line requires the statistics toolbox. [g, gn, gl] = grp2idx(values); fprintf('%30s : %4d\n',names{ix},max(g)); end

  • How do I make my MySQL query with joins more concise?

    - by John Hoffman
    I have a huge MySQL query that depends on JOINs. SELECT m.id, l.name as location, CONCAT(u.firstName, " ", u.lastName) AS matchee, u.email AS mEmail, u.description AS description, m.time AS meetingTime FROM matches AS m LEFT JOIN locations AS l ON locationID=l.id LEFT JOIN users AS u ON (u.id=m.user1ID) WHERE m.user2ID=2 UNION SELECT m.id, l.name as location, CONCAT(u.firstName, " ", u.lastName) AS matchee, u.email AS mEmail, u.description AS description, m.time AS meetingTime FROM matches AS m LEFT JOIN locations AS l ON locationID=l.id LEFT JOIN users AS u ON (u.id=m.user2ID) WHERE m.user1ID=2 The first 3 lines of each sub-statement divided by UNION are identical. How can I abide by the DRY principle, not repeat those three lines, and make this query more concise?

  • How to understand other people's CSS architectures?

    - by John
    I am reasonably good with CSS. However, when working with someone else's CSS, it's difficult for me to see the "bigger picture" in their architecture (but i have no problem when working with a CSS sheet I wrote myself). For example, I have no problems using Firebug to isolate and fix cross browser compatibility issues, or fixing a floating issue, or changing the height on a particular element. But if I'm asked to do something drastic such as, "I want the right sidebars of pages A, B, C and D to have a red border. I want the right side bars of pages E, F and G to have a blue border if and only if the user mouses over", then it takes me time a long time to map out all the CSS inheritance rules to see the "bigger picture". For some reason, I don't encounter the same difficulty with backend code. After a quick debriefing of how a feature works, and a quick inspection of the controller and model code, I will feel comfortable with the architecture. I will think, "it's reasonable to assume that there will be an Employee class that inherits from the Person Class that's used by a Department controller". If I discover inconvenient details that aren't consistent with overall architectural style, I am confident that I can hammer things back in place. With someone else's CSS work, it's much harder for me to see the "relationships" between different classes, and when and how the classes are used. When there are many inheritance rules, I feel overwhelmed. I'm having trouble articulating my question and issues... All I want to know is, why is it so much harder for me to see the bigger picture in someone else's CSS architecture than compared to someone else's business logic layer? **Does it have any thing to do with CSS being a relatively new technology, and there aren't many popular design patterns?

  • Django Problem - trying to access data entered into a form and feed it through a different page

    - by John Hoke
    OK, so let me give you an overview first. I have this site and in it there is a form section. When you access that section you can view or start a new project. Each project has 3-5 different forms. My problem is that I don't want viewers to have to go through all 3-5 pages to see the relevant information they need. Instead I want to give each project a main page where all the essential data entered into the forms is shown as non-editable data. I hope this makes sense. So I need to find a way to access all that data from the different forms for each project and to feed that data into the new page I'll be calling "Main". Each project will have a separate main page for itself. I'm pretty much clueless as to how I should do this, so any help at all would be appreciated. Thanks

  • How can I detect when the .NET Framework feature is "turned off" in Windows 7 / Vista?

    - by John Myczek
    My application requires the .NET Framework version 3.5. I recently ran into a customer that had the .NET Framework installed but turned off on Windows Vista (also applies to Windows 7). In this case, my installer (InstallShield 2009) does not prompt the user to install the Framework (because it is already installed) and when my application runs it crashes immediately. I tried another .NET application and it also crashes immediately. Is there any way to detect this situation and handle it more gracefully? Just detecting this during install is not ideal since the .NET Framework can be turned off at any time. Ideally, the application would be able to check and display a friendly message to the user telling them they need to turn on the .NET Framework. EDIT: "Turning off" the .NET Framework in Windows Vista or Windows 7 is not the same as uninstalling it. The Framework can be simply turned back on without reinstalling: http://windows.microsoft.com/en-US/windows-vista/Turn-Windows-features-on-or-off

  • String padding for a text template

    - by ndee
    I'm creating a PDF file from a txt-template with tcpdf ([Example 8][1]). The txt-template looks like this: SALUTATION FIRSTNAME LASTNAME STREET CURRENTDATE SOMEMOREINFORMATION MYWEBSITE I replace those markers with the correct value. So that it would look like this: Mr. John Doe Downingstreet 10 14th May, 2010 [email protected] www.stackoverflow.com In this example, when I replace the values, the indention of the date is dependent on the length of the street name (which I don't want). I could solve this issue with str_pad but the problem is, I normally use three columns and there are lines which only have content in col1 and col3 as in the last line. How can I solve that problem? Is there something like the "overwrite" function in Word, that when you write, the text just gets overwritten? Thanks in advance.
