  • C# - UpdateResource - To Remove A Resource

    - by Luke
    I am able to successfully add a resource to a file using UpdateResource and then remove it using: UpdateResource(HANDLE, "TYPE", "NUMER", 1033, IntPtr.Zero, 0); When I add a resource to the file it will add another even though there is an existing resource exactly the same, also I cannot remove any existing resources. When I try to remove an existing resource using that line I get the error ERROR_INVALID_PARAMETER. Any ideas?

  • CALayer and Off-Screen Rendering

    - by Luke Mcneice
    I have a Paging UIScrollView with a contentSize large enough to hold a number of small UIScrollViews for zooming, The viewForZoomingInScrollView is a viewController that holds a CALayer for drawing a PDF page onto. This allows me to navigate through a PDF much like the ibooks PDF reader. The code that draws the PDF (Tiled Layers) is located in: - (void)drawLayer:(CALayer *)layer inContext:(CGContextRef)ctx; And simply adding a 'page' to the visible screen calls this method automatically. When I change page there is some delay before all the tiles are drawn, even though the object (page) has already been created. What i want to be able to do is render the next page before the user scrolls to it, thus preventing the visible tiling effect. However, i have found that if the layer is located offscreen adding it to the scrollview doesn't call the drawLayer. Any Ideas/common gotchas here? I have tried: [viewController.view.layer setNeedsLayout]; [viewController.view.layer setNeedsDisplay]; NB: The fact that this is replicating the ibooks functionally is irrelevant within the context of the full app.

  • css layout - break down

    - by Luke
    So I am trying to get the effect of having two frames inside a 750px wide frame. .news {width: 750px;} .news1 {width:550px;} .news2 {width:200px;} Very simple css at this stage. The html/php: <div class="news"> <div class="format"><a href='newspiece.php?news=<?echo $id?>'><?echo "$subject\n";?></a></div> <div class="news1"> <? echo "<div class='content'>"; echo nl2br($comment); echo "<a href='newspiece.php?news=$id'>..[read more]..</a>\n"; echo "</div>"; ?> <h5><? echo "Posted by <a href=\"userprofile.php?user=$posted\">$posted</a> on $final_date\n";?></h5> <? echo "<br />\n";?> </div> <div class="news2"> <img src="images/news/<? echo $id?>.jpg" /> </div> </div>] THe problem I am getting is that the image that should be on the right is going underneath. So in effect, news1 is above news2, rather than side by side. Any ideas?

  • JAXB Web Services: Multiple Object Marshalling

    - by Luke Evans
    I can marshal and unmarshal 1 object with no problems (in netbeans); I need to know how to do this with multiple objects? I can't generate anything but null pointer exceptions when trying to unmarshal 3 objects into an array from XML; so I don't even know if I've marshalled the 3 out correctly. I know the basic idea of declaring the object, then using the jaxbu or jaxbm command, but I'd like to see this working for more than one object. **TLDR: How do I marshal/unmarshal multiple objects of a single class into/out of XML?? THANKS Code I have that marshals one object from XML: try { JAXBContext jc = JAXBContext.newInstance ("myOffers"); Unmarshaller u = jc.createUnmarshaller (); myOffers.Offer flight = (myOffers.Offer) u.unmarshal( new FileInputStream( "offers.xml" )); System.out.println ("Airline is : " + flight.getAirline()); System.out.println ("Origin is : " + flight.getOrigin()); System.out.println ("Destination is : " + flight.getDestination()); System.out.println ("Seats available : " + flight.getSeats()); System.out.println("Proximity to City Centre is : " + flight.getProximity()); System.out.println("Currency : " + flight.fare.getCurrency()); System.out.println("Value : " + flight.fare.getValue()); } catch (JAXBException e) { System.out.println("Error " + e);} ok so the Xml is: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <ns2:offer xmlns:ns2="http://simple.example.com/CInfoXmlDoc"> <Origin>Nottingham</Origin> <Destination>Istanbul</Destination> <Airline>Lufthansa</Airline> <Proximity>10</Proximity> <Seats>260</Seats> <Fare> <Currency>GBP</Currency> <Value>300</Value> </Fare> </ns2:offer> <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <ns2:offer xmlns:ns2="http://simple.example.com/CInfoXmlDoc"> <Origin>Birmingham</Origin> <Destination>Cairo</Destination> <Airline>Monarch</Airline> <Proximity>15</Proximity> <Seats>350</Seats> <Fare> <Currency>GBP</Currency> <Value>300</Value> </Fare> </ns2:offer> public static void main(String[] args) throws FileNotFoundException { int i = 0; int arraySize = 2; myOffers.Offer offer[] = new myOffers.Offer[arraySize]; offer[i] = new myOffers.Offer(); offer[i].fare = new myOffers.Offer.Fare(); offer[i].setAirline("Lufthansa"); offer[i].setOrigin("Nottingham"); offer[i].setDestination("Istanbul"); offer[i].setSeats(260); offer[i].setProximity(10); offer[i].fare.currency = "GBP"; offer[i].fare.value = 300; i++; offer[i] = new myOffers.Offer(); offer[i].fare = new myOffers.Offer.Fare(); offer[i].setAirline("Monarch"); offer[i].setOrigin("Birmingham"); offer[i].setDestination("Cairo"); offer[i].setSeats(350); offer[i].setProximity(15); offer[i].fare.currency = "GBP"; offer[i].fare.value = 300; try { int n = 0; FileOutputStream f = new FileOutputStream("offers.xml"); javax.xml.bind.JAXBContext jaxbCtx = javax.xml.bind.JAXBContext.newInstance(offer[n].getClass().getPackage().getName()); javax.xml.bind.Marshaller marshaller = jaxbCtx.createMarshaller(); marshaller.setProperty(javax.xml.bind.Marshaller.JAXB_ENCODING, "UTF-8"); //NOI18N marshaller.setProperty(javax.xml.bind.Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE); while (n < arraySize) { marshaller.marshal(offer[n], f); n++; } } catch (javax.xml.bind.JAXBException ex) { // XXXTODO Handle exception java.util.logging.Logger.getLogger("global").log(java.util.logging.Level.SEVERE, null, ex); //NOI18N } } Which was generated by my marshal code found here: public static void main(String[] args) throws FileNotFoundException { int i = 0; int arraySize = 2; myOffers.Offer offer[] = new myOffers.Offer[arraySize]; offer[i] = new myOffers.Offer(); offer[i].fare = new myOffers.Offer.Fare(); offer[i].setAirline("Lufthansa"); offer[i].setOrigin("Nottingham"); offer[i].setDestination("Istanbul"); offer[i].setSeats(260); offer[i].setProximity(10); offer[i].fare.currency = "GBP"; offer[i].fare.value = 300; i++; offer[i] = new myOffers.Offer(); offer[i].fare = new myOffers.Offer.Fare(); offer[i].setAirline("Monarch"); offer[i].setOrigin("Birmingham"); offer[i].setDestination("Cairo"); offer[i].setSeats(350); offer[i].setProximity(15); offer[i].fare.currency = "GBP"; offer[i].fare.value = 300; try { int n = 0; FileOutputStream f = new FileOutputStream("offers.xml"); javax.xml.bind.JAXBContext jaxbCtx = javax.xml.bind.JAXBContext.newInstance(offer[n].getClass().getPackage().getName()); javax.xml.bind.Marshaller marshaller = jaxbCtx.createMarshaller(); marshaller.setProperty(javax.xml.bind.Marshaller.JAXB_ENCODING, "UTF-8"); //NOI18N marshaller.setProperty(javax.xml.bind.Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE); while (n < arraySize) { marshaller.marshal(offer[n], f); n++; } } catch (javax.xml.bind.JAXBException ex) { // XXXTODO Handle exception java.util.logging.Logger.getLogger("global").log(java.util.logging.Level.SEVERE, null, ex); //NOI18N } } Apologies, I'm fining this editor quite appalling but thats another matter. Whats wrong with [code][/code] tags...

  • Image appearing in the wrong place.

    - by Luke
    I have a list that I want to precede on each line with a small image. The CSS: .left div.arrow{background-image: url(../images/design/box.png); float:left; height:15px; width:15px; margin-right:2px;} .left a.list:link, a:visited, a:active {color:black; font-size:0.8em; text-decoration:none; display:block; float:left;} The HTML: <div class="panel">My quick links</div> <div class="arrow"></div> <a href="/messages.php?p=new" class="list">Send a new message</a> <br /> <div class="arrow"></div> <a href="/settings.php#password" class="list">Change my password</a> <br /> <div class="arrow"></div> <a href="/settings.php#picture" class="list">Upload a new site image</a> <br /> As you can see, each image should go before the writing. On the first line, the text "Send a new message" has the preceeding image. However, each line afterwards has the image at the end. So "Send a new message" has an image at the start and finish. It is like the images are staying at the end of the previous line. Any ideas?

  • How To Replace @Resource Annotation with Java 1.4 Compliant Version

    - by Luke
    Hello, I have a test class that has a @Resource annotation for a setter and I need to make it Java 1.4 compliant, so obviously the annotation has to go. I'm using Spring. So, how would I replace something like @Resource("my.resource") so that the setter gets the correct dependency injection? Would I need to make a bean in an xml file? I'm pretty new to this so if I'm not providing enough information, let me know.

  • Helping Kohana 3 ORM to speed up a little

    - by Luke
    I noticed that Kohana 3 ORM runs a "SHOW FULL COLUMNS" for each of my models when I start using them: SHOW FULL COLUMNS FROM `mytable` This query might take a few clock cycles to execute (in the Kohana profiler it's actually the slowest of all queries ran in my current app). Is there a way to help Kohana 3 ORM to speed up by disabling this behaviour and explicitly define the columns in my models instead?

  • How can I integrate Java with .Net?

    - by Luke
    I have one SDK that is available in Java and another SDK that is available for .Net and would like to write a single application that interfaces with both of them. I imagine I will need to use a cross platform communication framework that can support named pipes (or other in memory communication), what is the best choice? After some more research I found Hessian -- does anyone know anything about the maturity of this project?

  • How can I expose an Objective-C function to JavaScript using WebKit on Mac OS X?

    - by Luke
    I understand to do this on the iPhone you need to trap link requests (as per my other iPhone question UIWebView Expose JavaScript) and you can easily do the reverse and access JavaScript from Obj-C code. However, I would like to have JavaScript be able to call some Objective-C functions that would somehow be registered with WebKit. I assume that you can do this better than trapping links like on the iPhone as on Mac OS X we have access to the full WebKit. I wish to basically do the reverse of Using JavaScript from Objective-C

  • While loop problems

    - by Luke
    I have put together the following code, the problem is that each while loop is only returning one set of data. $result = mysql_query("SELECT date FROM ".TBL_FIXTURES." WHERE compname = '$comp_name' GROUP BY date"); $i = 1; echo "<table cellspacing=\"10\" style='border: 1px dotted' width=\"300\" bgcolor=\"#eeeeee\">"; while ($row = mysql_fetch_assoc($result)) { $date=date("F j Y", $row['date']); echo $date; echo " <tr> <td>Fixture $i - Deadline on $date</td> </tr> "; $result = mysql_query("SELECT * FROM ".TBL_FIXTURES." WHERE compname = '$comp_name' AND date = '$row[date]' ORDER BY date"); while ($row = mysql_fetch_assoc($result)) { extract ($row); echo " <tr> <td>$home_user - $home_team V $away_user - $away_team</td> </tr> "; } $i++; } echo "</table>"; I should get many dates, and then each set of fixture below. At the moment, the first row from the first while loop is present, along with the data from the second while loop. However, it doesn't continue? Any ideas where I can correct this? Thanks

  • How to monitor delayed_job with monit

    - by Luke Francl
    Are there any examples on the web of how to monitor delayed_job with Monit? Everything I can find uses God, but I refuse to use God since long running processes in Ruby generally suck. (The most current post in the God mailing list? God Memory Usage Grows Steadily.) Update: delayed_job now comes with a sample monit config based on this question.

  • BlackBerry specific stylesheet

    - by Luke
    We want to use the same page to service the desktop, iPhone, and BlackBerry, so we have to come up with a way for the different devices to load different stylesheets. So, is there a way to specify a stylesheet to run on BlackBerry? For example, iPhone's use the media attribute: <link media="only screen and (max-device-width: 320px)" href="style.css" ...

  • GitHub solution for personal repo

    - by Luke Maurer
    So I've got my private SVN repo on my home server, and it has maybe 30 different modules thrown together in it, ranging from abortive throw-away larks to a few endeavors that might actually go somewhere someday. But a recent filesystem failure (BTW, never ever EVER use XFS without a battery-backed hardware RAID) has me spooked and thinking of using a DVCS for all that. I've also just had quite the swig of the Git koolaid, and I've been working with GitHub of late, so that's where I'm looking right now. Of course, it would be silly to shell out major cash for a separate private Git repo for every little project, and I don't want to have to be selective about what I throw up there (I love all my children :-D ), so I'll have to be somewhat creative about this. I can happily use SSH to my home box to use Git the way I've been using SVN, and I'm thinking from there I could amalgamate everything into, say, a big project with 30 submodules, which I then push to GitHub. What'd be a sane way to set this up? Does using submodules sound feasible? How do I sync it all to my private GitHub repo? Cron job? Git hook? I'd love to hear it if anyone's done something similar. I'm not really married to Git or GitHub, so a sufficiently compelling feature of another solution might sway me. But if your answer does involve a different system (especially a different VCS), be advised it'll be a tougher sell :-)

    So I have a query, can someone let me know if it looks ok content wise? "INSERT INTO ".TBL_MESSAGES."

    I am using a listview, and trying to populate using a file. I need the file to be read in as soon as the form starts. private void mainForm_Load(object sender, EventArgs e) { //get file read in if (File.Exists("../../MealDeliveries.txt")) { StreamReader sr = new StreamReader("../../MealDeliveries.txt"); //first line is delivery name string strDeliveryName = sr.ReadLine(); do { //other lines Delivery d = new Delivery(strDeliveryName, sr.ReadLine(), sr.ReadLine(), sr.ReadLine(), sr.ReadLine(), sr.ReadLine(), sr.ReadLine()); mainForm.myDeliveries.Add(d); //check for further values strDeliveryName = sr.ReadLine(); //stop if no more values } while (strDeliveryName != null); displayDeliveries(); } } Should this work?

  • Selectedindex in listview, throwing up an error!

    Hey guys, the following code shows what i am trying to do. private void btnEdit_Click(object sender, EventArgs e) { iDeliverySelected = lstDeliveryDetails.SelectedIndex; bool addEdit = false; } The selectedindex is throwing up the following error.. 'System.Windows.Forms.ListView' does not contain a definition for 'SelectedIndex' and no extension method 'SelectedIndex' accepting a first argument of type 'System.Windows.Forms.ListView' could be found (are you missing a using directive or an assembly reference?) Any ideas why? First time I have tried to use SelectedIndex, not sure if i am using it correctly?

  • How to add images while moving finger across UIView?

    - by Luke Irvin
    I am having issues adding an image across a view while moving finger across the screen. Currently it is adding the image multiple times but squeezing them too close together and not really following my touch. Here is what I am trying: -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch * touch = [touches anyObject]; touchPoint = [touch locationInView:imageView]; if (touchPoint.x > 0 && touchPoint.y > 0) { _aImageView = [[UIImageView alloc] initWithImage:aImage]; _aImageView.multipleTouchEnabled = YES; _aImageView.userInteractionEnabled = YES; [_aImageView setFrame:CGRectMake(touchPoint.x, touchPoint.y, 80.0, 80.0)]; [imageView addSubview:_aImageView]; [_aImageView release]; } } -(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { [self touchesBegan:touches withEvent:event]; } Any suggestions is much appreciated. EDIT: What I want: After taking or choosing an image, the user can then select another image from a list. I want the user to touch and move their finger across the view and the selected image will appear where they drag their finger, without overlapping, in each location.

  • linq to sql report tables in query

    - by luke
    Here's the method i want to write: public static IEnumerable<String> GetTableNames(this IQueryable<T> query) { //... } where the IQueryable is a linq-to-sql query (is there a more specific interface i should use?). then if i had a query like this var q = from c in db.Customers from p in db.Products where c.ID = 3 select new {p.Name, p.Version}; q.GetTableNames();// return ["Customers", "Products"] basically it would show all the tables that this query touches in the db, it is ok to execute the query to figure this out too (since that is going to happen anyway)? any ideas?

  • [C#] Three System.Drawing methods manifest slow drawing or flickery: Solutions? or Other Options?

    - by Luke Mcneice
    Hi all, I am doing a little graphing via the System.Drawing and im having a few problems. I'm holding data in a Queue and i'm drawing(graphing) out that data onto three picture boxes this method fills the picture box then scrolls the graph across. so not to draw on top of the previous drawings (and graduly looking messier) i found 2 solutions to draw the graph. Call plot.Clear(BACKGOUNDCOLOR) before the draw loop [block commented] although this causes a flicker to appear from the time it takes to do the actual drawing loop. call plot.DrawLine(channelPen[5], j, 140, j, 0); just before each drawline [commented] although this causes the drawing to start ok then slow down very quickly to a crawl as if a wait command had been placed before the draw command. Here is the Code for reference: /*plotx.Clear(BACKGOUNDCOLOR) ploty.Clear(BACKGOUNDCOLOR) plotz.Clear(BACKGOUNDCOLOR)*/ for (int j = 1; j < 599; j++) { if (j > RealTimeBuffer.Count - 1) break; QueueEntity past = RealTimeBuffer.ElementAt(j - 1); QueueEntity current = RealTimeBuffer.ElementAt(j); if (j == 1) { //plotx.DrawLine(channelPen[5], 0, 140, 0, 0); //ploty.DrawLine(channelPen[5], 0, 140, 0, 0); //plotz.DrawLine(channelPen[5], 0, 140, 0, 0); } //plotx.DrawLine(channelPen[5], j, 140, j, 0); plotx.DrawLine(channelPen[0], j - 1, (((past.accdata.X - 0x7FFF) / 256) + 64), j, (((current.accdata.X - 0x7FFF) / 256) + 64)); //ploty.DrawLine(channelPen[5], j, 140, j, 0); ploty.DrawLine(channelPen[1], j - 1, (((past.accdata.Y - 0x7FFF) / 256) + 64), j, (((current.accdata.Y - 0x7FFF) / 256) + 64)); //plotz.DrawLine(markerPen, j, 140, j, 0); plotz.DrawLine(channelPen[2], j - 1, (((past.accdata.Z - 0x7FFF) / 256) + 94), j, (((current.accdata.Z - 0x7FFF) / 256) + 94)); } Is there any tricks to avoid these overheads? If not would there be any other/better solutions?
