• Cant correctly install Lazarus

  - by user206316

  I have a little problem with installing and running Lazarus. I just upgrade ubuntu from 13.04 to 13.10. When i had 13.04, i could install lazarus without any problems, but in 13.10 lazarus magicaly dissapeared, and when i tried install it from ubuntu software center, it said something like in my software resources lazarus-ide-0.9.30.4 doesnt exist. After some research on net i tried delete all files from earlier installations, download deb packages from sourceforge and install them, but when i want to instal fpc-src, error shows up with output: (Reading database ... 100% (Reading database ... 239063 files and directories currently installed.) Unpacking fpc-src (from .../Stiahnut/Lazarus/fpc-src.deb) ... dpkg: error processing /home/richi/Stiahnut/Lazarus/fpc-src.deb (--install): trying to overwrite '/usr/share/fpcsrc/2.6.2/rtl/nativent/tthread.inc', which is also in package fpc-source-2.6.2 2.6.2-5 dpkg-deb (subprocess): decompressing archive member: internal gzip write error: Broken pipe dpkg-deb: error: subprocess <decompress> returned error exit status 2 dpkg-deb (subprocess): cannot copy archive member from '/home/richi/Stiahnut/Lazarus/fpc-src.deb' to decompressor pipe: failed to write (Broken pipe) when i started lazarus, it of course tell me that it cant find fpc compier and fpc sources. So, please, i really need program for school and i dont wanna reinstall os anymore or something like that :( (Ubuntu 13.10 64bit) P.S: im not skilled in linux so if u know some commands to fix it just write them for copy and paste :) P.P.S:Sorry for bad English, im Slovak xD P.P.P.S: Thank so much for any answers update: output from sudo dpkg -l | grep "^rc" richi@Richi-Ubuntu:~/lazarus1.0.12$ sudo dpkg -l | grep "^rc" rc account-plugin-generic-oauth 0.10bzr13.03.26-0ubuntu1.1 amd64 GNOME Control Center account plugin for single signon -

• JPA - insert and retrieve clob and blob types

  - by pachunoori.vinay.kumar(at)oracle.com

  This article describes about the JPA feature for handling clob and blob data types.You will learn the following in this article. @Lob annotation Client code to insert and retrieve the clob/blob types End to End ADFaces application to retrieve the image from database table and display it in web page. Use Case Description Persisting and reading the image from database using JPA clob/blob type. @Lob annotation By default, TopLink JPA assumes that all persistent data can be represented as typical database data types. Use the @Lob annotation with a basic mapping to specify that a persistent property or field should be persisted as a large object to a database-supported large object type. A Lob may be either a binary or character type. TopLink JPA infers the Lob type from the type of the persistent field or property. For string and character-based types, the default is Clob. In all other cases, the default is Blob. Example Below code shows how to use this annotation to specify that persistent field picture should be persisted as a Blob. public class Person implements Serializable {    @Id    @Column(nullable = false, length = 20)    private String name;    @Column(nullable = false)    @Lob    private byte[] picture;    @Column(nullable = false, length = 20) } Client code to insert and retrieve the clob/blob types Reading a image file and inserting to Database table Below client code will read the image from a file and persist to Person table in database.                       Person p=new Person();                      p.setName("Tom");                      p.setSex("male");                      p.setPicture(writtingImage("Image location"));// - c:\images\test.jpg                       sessionEJB.persistPerson(p); //Retrieving the image from Database table and writing to a file                       List<Person> plist=sessionEJB.getPersonFindAll();//                      Person person=(Person)plist.get(0);//get a person object                      retrieveImage(person.getPicture());   //get picture retrieved from Table //Private method to create byte[] from image file  private static byte[] writtingImage(String fileLocation) {      System.out.println("file lication is"+fileLocation);     IOManager manager=new IOManager();        try {           return manager.getBytesFromFile(fileLocation);                    } catch (IOException e) {        }        return null;    } //Private method to read byte[] from database and write to a image file    private static void retrieveImage(byte[] b) {    IOManager manager=new IOManager();        try {            manager.putBytesInFile("c:\\webtest.jpg",b);        } catch (IOException e) {        }    } End to End ADFaces application to retrieve the image from database table and display it in web page. Please find the application in this link. Following are the j2ee components used in the sample application. ADFFaces(jspx page) HttpServlet Class - Will make a call to EJB and retrieve the person object from person table.Read the byte[] and write to response using Outputstream. SessionEJBBean - This is a session facade to make a local call to JPA entities JPA Entity(Person.java) - Person java class with setter and getter method annotated with @Lob representing the clob/blob types for picture field.

Only clue I have is that I initially was having problems, tried using the old method of fixing isights (involving installing isight-firmware-tools) before realizing that I just hadn't turned on the VM setting to allow the VM to access the webcam. :) Anyway, I wonder if installing that messed something up. However, I think this is a red herring because I've: shut down and turned back on the Mac, restarted the VM, tried a different VM (for which I never installed isight-firmware-tools, and created an entirely new ubuntu vm. All instances have had this problem. Similarly, other viewers, such as cheese, avplay, avconv have had all various kinds of errors.

• WPF WriteableBitmap Memory Leak?

  - by Mario

  Hello, everyone! I'm trying to figure out how to release a WriteableBitmap memory. In the next section of code I fill the backbuffer of a WriteableBitmap with a really large amount of data from "BigImage" (3600 * 4800 px, just for testing) If I comment the lines where bitmap and image are equaled to null, the memory it´s not release and the application consumes ~230 MB, even when Image and bitmap are no longer used! As you can see at the end of the code its necessary to call GC.Collect() to release the memory. So the question is, what is the right way to free the memory used by a WriteableBitmap object? Is GC.Collect() the only way? Any help would be great. PS. Sorry for my bad english. private void buttonTest_Click(object sender, RoutedEventArgs e) { Image image = new Image(); image.Source = new BitmapImage(new Uri("BigImage")); WriteableBitmap bitmap = new WriteableBitmap( (BitmapSource)image.Source); bitmap.Lock(); // Bitmap processing bitmap.Unlock(); image = null; bitmap = null; GC.Collect(); }

• AutoMapper is not working for a Container class

  - by rboarman

  Hello, I have an AutoMapper issue that has been driving me crazy for way too long now. A similar question was also posted on the AutoMapper user site but has not gotten much love. The summary is that I have a container class that holds a Dictionary of components. The components are a derived object of a common base class. I also have a parallel structure that I am using as DTO objects to which I want to map. The error that gets generated seems to say that the mapper cannot map between two of the classes that I have included in the CreateMap calls. I think the error has to do with the fact that I have a Dictionary of objects that are not part of the container‘s hierarchy. I apologize in advance for the length of the code below. My simple test cases work. Needless to say, it’s only the more complex case that is failing. Here are the classes: #region Dto objects public class ComponentContainerDTO { public Dictionary<string, ComponentDTO> Components { get; set; } public ComponentContainerDTO() { this.Components = new Dictionary<string, ComponentDTO>(); } } public class EntityDTO : ComponentContainerDTO { public int Id { get; set; } } public class ComponentDTO { public EntityDTO Owner { get; set; } public int Id { get; set; } public string Name { get; set; } public string ComponentType { get; set; } } public class HealthDTO : ComponentDTO { public decimal CurrentHealth { get; set; } } public class PhysicalLocationDTO : ComponentDTO { public Point2D Location { get; set; } } #endregion #region Domain objects public class ComponentContainer { public Dictionary<string, Component> Components { get; set; } public ComponentContainer() { this.Components = new Dictionary<string, Component>(); } } public class Entity : ComponentContainer { public int Id { get; set; } } public class Component { public Entity Owner { get; set; } public int Id { get; set; } public string Name { get; set; } public string ComponentType { get; set; } } public class Health : Component { public decimal CurrentHealth { get; set; } } public struct Point2D { public decimal X; public decimal Y; public Point2D(decimal x, decimal y) { X = x; Y = y; } } public class PhysicalLocation : Component { public Point2D Location { get; set; } } #endregion The code: var entity = new Entity() { Id = 1 }; var healthComponent = new Health() { CurrentHealth = 100, Owner = entity, Name = "Health", Id = 2 }; entity.Components.Add("1", healthComponent); var locationComponent = new PhysicalLocation() { Location = new Point2D() { X = 1, Y = 2 }, Owner = entity, Name = "PhysicalLocation", Id = 3 }; entity.Components.Add("2", locationComponent); Mapper.CreateMap<ComponentContainer, ComponentContainerDTO>() .Include<Entity, EntityDTO>(); Mapper.CreateMap<Entity, EntityDTO>(); Mapper.CreateMap<Component, ComponentDTO>() .Include<Health, HealthDTO>() .Include<PhysicalLocation, PhysicalLocationDTO>(); Mapper.CreateMap<Component, ComponentDTO>(); Mapper.CreateMap<Health, HealthDTO>(); Mapper.CreateMap<PhysicalLocation, PhysicalLocationDTO>(); Mapper.AssertConfigurationIsValid(); var targetEntity = Mapper.Map<Entity, EntityDTO>(entity); The error when I call Map() (abbreviated stack crawls): AutoMapper.AutoMapperMappingException was unhandled Message=Trying to map MapperTest1.Entity to MapperTest1.EntityDTO.

• Programmatically add an ISAPI extension dll in IIS 7 using ADSI?

  - by fretje

  I apologize beforehand, this is a cross post of this SO question. I thought I'd ask it there first, but apparently it doesn't harvest any answers there. I hope it will get more attention here. When I have an answer somewhere, I'll delete the other one. I'm trying to programmatically add an ISAPI extension dll in IIS using ADSI. This has been working for ages on previous versions of IIS, but it seems to fail on IIS 7. I am using similar code like shown in this question: var web = GetObject("IIS://localhost/W3SVC/1/ROOT/specificVirtualDirectory"); var maps = web.ScriptMaps.toArray(); map[maps.length] = ".aaa,c:\\path\\to\\isapi\\extension.dll,1,GET,POST"; web.ScriptMaps = maps.asDictionary(); web.SetInfo(); After executing that code, I do see an "AboMapperCustom-12345678" entry for that specific dll in the "Handler mappings" of the specific virtual directory in which I added the script map. But when I try to use that extension in a browser, I always get HTTP Error 404.2 Not Found The page you are requesting cannot be served because of the ISAPI and CGI Restriction list settings on the Web server. Even after adding an entry to allow that specific dll in the "ISAPI and CGI restrictions", I keep getting that error. To make it actually work, I first have to undo these steps (encountering the same issue like the OP of the question mentioned above: after deleting the script map entry from the IIS manager GUI, I also have to programmatically delete it using ADSI before it's actually gone from the metabase). And then manually add an entry like this: inetmgr - webserver - website - virtual directory - handler mappings - add script map... path = *.dll, executable = <path to dll>, name = <doesn't matter, but it's mandatory> click "yes" on the question "do you want to allow this ISAPI extension?" When I compare the 2 entries, they are exactly the same, except for the "Entry Type" which seems to be "Inherited" for the programmatically added one and "Local" for the one added manually. The strange thing is, even though it says "Inherited", I don't see it anywhere in IIS on a higher level. Where is it inheriting from? In my code, I do add the script map to the specific virtual directory so it should be "Local" as well. Maybe there is the problem, but I don't know how to add a "Local" Script Map using ADSI. I really would like to keep using the ADSI method, as otherwise I will have to use different methods in our setup when working with IIS 7 or previous versions, and I would like to avoid that. To recap: How can I programmatically add a script map entry and its companion CGI and ISAPI restrictions entry to IIS 7 using ADSI? Anybody who can shed some light on this? Any help appreciated.

• App using MonoTouch Core Graphics mysteriously crashes

  - by Stephen Ashley

  My app launches with a view controller and a simple view consisting of a button and a subview. When the user touches the button, the subview is populated with scrollviews that display the column headers, row headers, and cells of a spreadsheet. To draw the cells, I use CGBitmapContext to draw the cells, generate an image, and then put the image into the imageview contained in the scrollview that displays the cells. When I run the app on the iPad, it displays the cells just fine, and the scrollview lets the user scroll around in the spreadsheet without any problems. If the user touches the button a second time, the spreadsheet redraws and continues to work perfectly, If, however, the user touches the button a third time, the app crashes. There is no exception information display in the Application Output window. My first thought was that the successive button pushes were using up all the available memory, so I overrode the DidReceiveMemoryWarning method in the view controller and used a breakpoint to confirm that this method was not getting called. My next thought was that the CGBitmapContext was not getting released and looked for a Monotouch equivalent of Objective C's CGContextRelease() function. The closest I could find was the CGBitmapContext instance method Dispose(), which I called, without solving the problem. In order to free up as much memory as possible (in case I was somehow running out of memory without tripping a warning), I tried forcing garbage collection each time I finished using a CGBitmapContext. This made the problem worse. Now the program would crash moments after displaying the spreadsheet the first time. This caused me to wonder whether the Garbage Collector was somehow collecting something necessary to the continued display of graphics on the screen. I would be grateful for any suggestions on further avenues to investigate for the cause of these crashes. I have included the source code for the SpreadsheetView class. The relevant method is DrawSpreadsheet(), which is called when the button is touched. Thank you for your assistance on this matter.

• Single player 'pong' game

  - by Jam

  I am just starting out learning pygame and livewires, and I'm trying to make a single-player pong game, where you just hit the ball, and it bounces around until it passes your paddle (located on the left side of the screen and controlled by the mouse), which makes you lose. I have the basic code, but the ball doesn't stay on the screen, it just flickers and doesn't remain constant. Also, the paddle does not move with the mouse. I'm sure I'm missing something simple, but I just can't figure it out. Help please! Here's what I have: from livewires import games import random games.init(screen_width=640, screen_height=480, fps=50) class Paddle(games.Sprite): image=games.load_image("paddle.bmp") def __init__(self, x=10): super(Paddle, self).__init__(image=Paddle.image, y=games.mouse.y, left=10) self.score=games.Text(value=0, size=25, top=5, right=games.screen.width - 10) games.screen.add(self.score) def update(self): self.y=games.mouse.y if self.top<0: self.top=0 if self.bottom>games.screen.height: self.bottom=games.screen.height self.check_collide() def check_collide(self): for ball in self.overlapping_sprites: self.score.value+=1 ball.handle_collide() class Ball(games.Sprite): image=games.load_image("ball.bmp") speed=5 def __init__(self, x=90, y=90): super(Ball, self).__init__(image=Ball.image, x=x, y=y, dx=Ball.speed, dy=Ball.speed) def update(self): if self.right>games.screen.width: self.dx=-self.dx if self.bottom>games.screen.height or self.top<0: self.dy=-self.dy if self.left<0: self.end_game() self.destroy() def handle_collide(self): self.dx=-self.dx def end_game(self): end_message=games.Message(value="Game Over", size=90, x=games.screen.width/2, y=games.screen.height/2, lifetime=250, after_death=games.screen.quit) games.screen.add(end_message) def main(): background_image=games.load_image("background.bmp", transparent=False) games.screen.background=background_image paddle_image=games.load_image("paddle.bmp") the_paddle=games.Sprite(image=paddle_image, x=10, y=games.mouse.y) games.screen.add(the_paddle) ball_image=games.load_image("ball.bmp") the_ball=games.Sprite(image=ball_image, x=630, y=200, dx=2, dy=2) games.screen.add(the_ball) games.mouse.is_visible=False games.screen.event_grab=True games.screen.mainloop() main()

• Google Streetview under V3 Code having hiccups and delays

  - by jeffkee

  http://new.brocksmeaton.com/showlisting.php/196/-7210-Arbutus-Place-Whytecliff-West-Vancouver-west-vancouver-real-estate The really odd thing is I had this working yesterday and today it's not working. I'm using jQuery UI to switch the tabs on the location map/street view module. I've recently upgraded the Google Maps code as well as the Google Streetview code to version 3. So when I open it in Firefox, with Firebug on, as soon as I switch to the Streetview tab, the navigation and zoom in out controls show, but nothing shows.. and then when I try to drag the map around, it does not move around, but instead, causes errors in Firebug: "too much recursion". So it causes the whole browser to become buggy, slows down, and the errors happen, and nothing shows on the streetview pane. Most of the map loading code is located in inline Javascript on the page itself. Some of the code is under showlisting.js <script type="text/javascript" src="/js/showlisting.js"></script> <script type="text/javascript"> // Call this function when the page has been loaded function loadmap() { var latlng = new google.maps.LatLng(49.374918567425475, -123.28996885871596); var myOptions = { zoom: 14, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map(document.getElementById('listingmap'), myOptions); var listingicon = '/images/activehouse.png'; var infowindow = new google.maps.InfoWindow(); homemarker = new google.maps.Marker({position: latlng, map: map, icon: listingicon}); google.maps.event.addListener(homemarker, 'click', function() { infowindow.setContent('<div style="height:80px; width:250px; color:#333;"><p>7210 Arbutus Place<br />Whytecliff, West Vancouver</div>') infowindow.open(map,homemarker); }); } function loadpano() { var latlng = new google.maps.LatLng(49.374918567425475, -123.28996885871596); $('#listingpanorama').slideDown(500, function() { var panoramaOptions = { addressControl:false, position: latlng, pov: { heading: 34, pitch: 30, zoom: 1 } }; var panorama = new google.maps.StreetViewPanorama(document.getElementById('listingpanorama'), panoramaOptions); }); return false; } </script> My old one under GOogle API Version 2 is here FYI if you want to take a look at it: http://demo.brixwork.com/master/showlisting.php/63/1701-388-Drake-Street-False-Creek-North-Vancouver-

• UIImageWriteToSavedPhotosAlbum with malloc_error

  I have an NIB file with a button. When I click this button, the setWallpaper: selector is called. Everything works as expected (the image is saved), excepte by the error thrown by malloc. malloc: *** error for object 0x184d000: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug I've set a breakpoint at malloc_error_break, but I don't understand anything from the debugger. I couldn't even find the object 0x184d000. Does anyone know why is this happening? I had also tried to retain the UIImage before sending it to UIImageWriteToSavedPhotosAlbum, but without success.

• how to show a large jpg image to the right in jqGrid's edit form ?

  - by cLee

  Is it possible to show a large (i.e. bigger than a thumbnail) jpeg image in the right-hand side of jqGrid's edit form ? Users want to look at a photo while entering data into fields ... they are describing things in the photo. I'm sure all things are possible with jQuery, but I don't know where to begin. thanks ... html: function afterSubmit(r, data, action) { // if session timeout returned: if (r.responseText == "logout") { window.location = '../scripts/logout.php'; } // if an error message is returned: if (r.responseText != "") { $('#submit_errors').html('Alert:'+r.responseText+''); // show div with error message $('#submit_errors').slideDown(); // hide error div after 10 seconds window.setTimeout(function() { $('#submit_errors').slideUp(); }, 10000); return false; // don't remove this! } return true; // don't remove this! } var lastsel; jQuery(document).ready(function(){ var mygrid = jQuery("#mobile_incidents").jqGrid({ url:'list.php?q=e', editurl:'edit.php', datatype: "json", // note: all column names are required even though some columns are hidden colNames:['Rec#','Date','Line','Photo'], colModel:[{ name:'id', index:'id', editable:true, editoptions: {readonly:'readonly'} }, { name:'mobile_discoveryDate', index:'mobile_discoveryDate', sortable:false, editable:true, edittype:'text', formatter:'date', formatoptions:{ srcformat:'Y/m/d', newformat:'m/d/Y' }, editoptions:{ size:12, maxlength:10, dataInit: function(element) { $(element).blur(); $(element).datepicker({dateFormat:'mm/dd/yyyy'}) } } }, { name:'mobile_lineName', index:'mobile_lineName', editable:true, sortable:false}, { name:'mobile_photo_name', index:'mobile_photo_name', editable:false, sortable:false} ], pager: '#mobile_incidents_pager', altRows: false, rowNum:10, rowList:[10,20], imgpath: '../include/images/jqgrid', viewrecords: true, emptyrecords:'No submissions found!', height: 260, sortname: 'id', sortorder: 'desc', gridview: true, scrollrows: true, autowidth: true, rownumbers: false, multiselect: false, subGrid:false, caption: '' }) .navGrid('#mobile_incidents_pager', // params: {add:false, edit:true, del:false, search:false, view:false, refresh:true, alertcap:' to edit:', alerttext:' . . . click on a row to highlight' }, // edit params: {top:50, left:5, editCaption: 'Edit Submission', bSubmit: 'Approve/Save', closeAfterEdit:true, afterSubmit:function(r,data){return afterSubmit(r,data,'edit');} }, {}, // add params {}, // delete params // search params: {multipleSearch: false}, // view params: {top: 150, left: 5, caption: 'View Mobile Rail Submission'} ); });

• iPhone: CATiledLayer/UIScrollView wont scroll after zooming and only zooms to anchor point

  - by Brodie4598

  Here is the problem... I am using CA Tiled Layer to display a large jpg. The view loads okay, and when I go to scroll around, it works fine. However, as soon as I zoom in or out once, it scrolls to the top left (to the anchor point) and will not scroll at all. The zooming works fine, but I just cannot scroll. Here is my code: #import <QuartzCore/QuartzCore.h> #import "PracticeViewController.h" @implementation practiceViewController //@synthesize image; - (void)viewDidLoad { NSString *path = [[NSBundle mainBundle] pathForResource:@"H-5" ofType:@"jpg"]; NSData *data = [NSData dataWithContentsOfFile:path]; image = [UIImage imageWithData:data]; CGRect pageRect = CGRectMake(0, 0, image.size.width, image.size.height); CATiledLayer *tiledLayer = [CATiledLayer layer]; tiledLayer.anchorPoint = CGPointMake(0.0f, 1.0f); tiledLayer.delegate = self; tiledLayer.tileSize = CGSizeMake(1000, 1000); tiledLayer.levelsOfDetail = 6; tiledLayer.levelsOfDetailBias = 0; tiledLayer.bounds = pageRect; tiledLayer.transform = CATransform3DMakeScale(1.0f, -1.0f, 0.3f); myContentView = [[UIView alloc] initWithFrame:self.view.bounds]; [myContentView.layer addSublayer:tiledLayer]; UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:self.view.bounds]; scrollView.delegate = self; scrollView.contentSize = pageRect.size; scrollView.minimumZoomScale = .2; scrollView.maximumZoomScale = 1; [scrollView addSubview:myContentView]; [self.view addSubview:scrollView]; } - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView { return myContentView; } - (void)drawLayer:(CALayer *)layer inContext:(CGContextRef)ctx { NSString *path = [[NSBundle mainBundle] pathForResource:@"H-5" ofType:@"jpg"]; NSData *data = [NSData dataWithContentsOfFile:path]; image = [UIImage imageWithData:data]; CGRect imageRect = CGRectMake (0.0, 0.0, image.size.width, image.size.height); CGContextDrawImage (ctx, imageRect, [image CGImage]); } @end

• How effective can this Tagging solution be?

  - by Pablo

  Im working on an image sharing site and want to implement tagging for the images. I've read Questions #20856 and #2504150 I have few concerns with the approach on the questions above. First of all it looks easy to link an image to a tag. However getting images by tag relation is not as easy. Not easy because you will have to get the image-to-tag relation from one table and then make a big query with a bunch of OR statements( one OR for every image). Before i even research the tagging topic i started testing the following method: This tables as examples: Table: Image Columns: ItemID, Title, Tags Table: Tag Columns: TagID, Name The Tags column in the Image table takes a string with multiple tagID from the Tag table enclosed by dashes(-). For example: -65-25-105- Links an image with the TagID 65,25 and 105. With this method i find it easier to get images by tag as i can get the TagID with one query and get all the images with another simple query like: SELECT * FROM Image WHERE Tags LIKE %-65-% So if i use this method for tagging, How effective this is? Is querying by LIKE %-65-% a slow process? What problems can i face in the future?

• Can an SATA hard drive image be restored onto an SSD?

  - by Bryan Parker

  I'm currently using an SATA hard drive on my primary dev machine, but planning to upgrade to an SSD at some point soon. I use TrueImage on a regular basis to make backups, and to upgrade my harddrive without reinstalling everything. Will I be able to restore and boot onto an SSD? Will there be a performance hit or other issues to watch out for?

• Make backup image (.tib/.vhd) as my main operating system?

  - by Joann

  My old hard drive is dying so I want to move my Windows 7 operating system to another hard drive. They say cloning using Acronis would do the trick, but for some reason it refuses to work. I also tried EASEUS Todo Backup, but it doesn't work either. Can you recommend some suggestions on how to transfer my operating system? I heard about converting .tib to .vhd and then booting from it, but does that achieve the same effect as cloning?
