• Stacking two pictures with captions side by side and centered in Wordpress

  - by Jim

  Hi all - this is driving me absolutely nuts. I'm not the most experienced with CSS, so I'm hoping it is something simple. I'm running Wordpress 2.9.2 with "The Morning After" theme. I am trying to write a post where I want to display two small pictures, with captions, side-by-side and centered in the middle of the page. Here is the HTML code I am using to display the images: [caption align="alignnone" width="150" caption="Protein rest"] <a href="http://www.mysite.com/wp-content/uploads/2008/06/protein-rest.jpg"> <img title="Mash during protein rest" src="http://www.mysite.com/wp-content/uploads/2008/06/protein-rest-150x144.jpg" alt="Mash during protein rest" width="150" height="144" /> </a>[/caption] [caption align="alignnone" width="143" caption="Saccharification rest" captionalign="center"] <a href="http://www.mysite.com/wp-content/uploads/2008/06/saccharification-rest.jpg"> <img title="Mash during saccharification rest" src="http://www.mysite.com/wp-content/uploads/2008/06/saccharification-rest-143x150.jpg" alt="Mash during saccharification rest" width="143" height="150" /> </a>[/caption] I tried using "aligncenter" and "alignleft" for the caption align - if I use "alignleft" the pictures are lined up perfectly, but all the way to the left of the page. If I use "aligncenter" the pics are in the center, but stacked one on top of the other. My first thought was to wrap the images in a div using: <div style="text-align:center;">image code</div> but that doesn't work. Now, if I wrap in a centered div like that and omit the [caption] tags, it works, but I need the captions. Those caption tags are translated by Wordpress into it's own div of class wp-caption. I've also tried wrapping each separate image in its own div within a parent centered div wrapper. Here is the pertinent parts of the style.css - please let me know if you need any other info, and if you can help me, I will postpone jumping off the nearest bridge! Thanks!! Style.css: .aligncenter, div.aligncenter { display: block; margin: 14px auto; } .alignleft { float: left; margin: 0 14px 10px 0; } .alignright { float: right; margin: 0 0 10px 14px; } .wp-caption { border: 1px solid #ddd; text-align: center; background-color: #f3f3f3; padding-top: 4px; /* optional rounded corners for browsers that support it */ -moz-border-radius: 3px; -khtml-border-radius: 3px; -webkit-border-radius: 3px; border-radius: 3px; } .wp-caption img { margin: 0; padding: 0; border: 0 none; } .wp-caption p.wp-caption-text { font-size: 11px; line-height: 14px; padding: 5px 4px 5px 5px; margin: 0; } PS - I am aware of the Gallery feature available in Wordpress, but would like to avoid it and would love to understand why wrapping in a div doesn't move the whole kit to the center. Finally, just for the sake of completeness, here is the source of the page when loaded using the div wrapper and image code as above (so you can see how Wordpress translates the caption tags): <div style="text-align:center;"> <div class="wp-caption alignnone" style="width: 160px"> <a href="http://www.mysite.com/wp-content/uploads/2008/06/protein-rest.jpg"> <img title="Mash during protein rest" src="http://www.mysite.com/wp-content/uploads/2008/06/protein-rest-150x144.jpg" alt="Mash during protein rest" width="150" height="144" /> </a> <p class="wp-caption-text" style="text-align:center">Protein rest</p> </div> <div class="wp-caption alignnone" style="width: 153px"> <a href="http://www.mysite.com/wp-content/uploads/2008/06/saccharification-rest.jpg"> <img title="Mash during saccharification rest" src="http://www.mysite.com/wp-content/uploads/2008/06/saccharification-rest-143x150.jpg" alt="Mash during saccharification rest" width="143" height="150" /> </a> <p class="wp-caption-text" style="text-align:center">Saccharification rest</p> </div> </div>

• How to represent a Board Panel in Java for a game ?

  - by FILIaS

  I wanna fix a 2D board for a game. I've already fixed other panels for the Gui and everything goes well. But the panel for the board cant be printed on the window. I'm a bit confused about it as i think i've followed the same ideas as for the others panels i need. Here's what i've done: EDIT:*EDIT* what i'm trying to do is fix a board panel for the game according to the dimensions of the it,hold every square in an array in order to use it after wherever it;s needed. I draw each little square of it with the method draw and put it back to the panel. So, each square on the board is a panel. This is the idea. But as u can see. There are troubles/errors on it. EDIT: code updated. just found a part of the problem. i thought first that i had set background to squared, but i didnt. with this one it appears on the panel a wide black "column". Unfortunately,still none squares. :( One More EDIT: Also,i realized that draw method is never called. when i put the draw method in the following method i can see the squares but they remain small. I redefine them with setSize but still no change. How can I use paint method to edit the panels properly???? As it is now it can't. Even it can't return an object(eg panel) as it's polymorphic void! /** *Method used to construct the square in the area of the *gui's grid. In this stage a GUISquare array is being constructed, * used in the whole game as *a mean of changing a square graphical state. *@param squares is the squares array from whom the gui grid will be *constructed. *@see getSquare about the correspondance beetween a squareModel and * a GUISquare. */ private void initBoardPanel(SquareModel[][] squares){ BoardPanel.setLayout(new GridLayout(height ,width )); //set layout SquareRenderer[][] Squares; JPanel[][] grid; Squares=new GUISquare[height][width()]; grid=new JPanel[height()][width()]; for (int i=0; i<height(); i++){ for (int j=0; j<width() ; j++){ SquareRenderer kou=new SquareRenderer(i,j); kou.setSquare(myGame.getSquares()[i][j]); //NOTE: THE FOLLOWING DRAW METHOD CANT BE CALLED!!!? if (myGame.getSquares()[i][j] instanceof SimpleSq ){ kou .paintPanel(i,j,"");} else if (myGame.getSquares()[i][j] instanceof ActionSq ) { kou .paintPanel(i,j); } //JUST BECAUSE DRAW CANT BE CALLED I PUT ITS CODE HERE: //JUST TO CHECK: JPanel panel = new JPanel(); panel.setLayout(new BorderLayout()); JLabel label1 = new JLabel("Move To "+myGame.getSquares()[i][j].getGoTo()); JLabel label2 = new JLabel(""+myGame.getSquares()[i][j].getSquare()); panel.setBackground(Color.ORANGE); panel.add(label2, BorderLayout.NORTH); panel.add(label1, BorderLayout.CENTER); panel.setSize(250,250); ///////// <--until here ---paint method<--- kou.add(panel); kou.setVisible(true); kou.setBackground(Color.BLACK); Squares[i][j]= kou; BoardPanel.add(kou); BoardPanel.setVisible(true); BoardPanel.setBackground(Color.WHITE); } } this.add(BoardPanel,BorderLayout.WEST); // this.pack(); //sets appropriate size for frame this.setVisible(true); //makes frame visible } IMPLEMENTED BY SQUARERENDERER: /** * Transformer for Snake/Ladder * <br>This method is used to display a square on the screen. */ public void paintPanel(int i,int j) { JPanel panel = new JPanel(); panel.setLayout(new BorderLayout()); JLabel label1 = new JLabel("Move To"+myGame.getSquares()[i][j].getGoTo()); JLabel label2 = new JLabel(""+myGame.getSquares()[i][j].getSquare()); JSeparator CellSeparator = new JSeparator(orientation); panel.add(CellSeparator); panel.setForeground(Color.ORANGE); panel.add(label2, BorderLayout.NORTH); panel.add(label1, BorderLayout.CENTER); }

• Convert Decimal to ASCII

  - by Dan Snyder

  I'm having difficulty using reinterpret_cast. Before I show you my code I'll let you know what I'm trying to do. I'm trying to get a filename from a vector full of data being used by a MIPS I processor I designed. Basically what I do is compile a binary from a test program for my processor, dump all the hex's from the binary into a vector in my c++ program, convert all of those hex's to decimal integers and store them in a DataMemory vector which is the data memory unit for my processor. I also have instruction memory. So When my processor runs a SYSCALL instruction such as "Open File" my C++ operating system emulator receives a pointer to the beginning of the filename in my data memory. So keep in mind that data memory is full of ints, strings, globals, locals, all sorts of stuff. When I'm told where the filename starts I do the following: Convert the whole decimal integer element that is being pointed to to its ASCII character representation, and then search from left to right to see if the string terminates, if not then just load each character consecutively into a "filename" string. Do this until termination of the string in memory and then store filename in a table. My difficulty is generating filename from my memory. Here is an example of what I'm trying to do: C++ Syntax (Toggle Plain Text) 1.Index Vector NewVector ASCII filename 2.0 240faef0 128123792 'abc7' 'a' 3.0 240faef0 128123792 'abc7' 'ab' 4.0 240faef0 128123792 'abc7' 'abc' 5.0 240faef0 128123792 'abc7' 'abc7' 6.1 1234567a 243225 'k2s0' 'abc7k' 7.1 1234567a 243225 'k2s0' 'abc7k2' 8.1 1234567a 243225 'k2s0' 'abc7k2s' 9. //EXIT LOOP// 10.1 1234567a 243225 'k2s0' 'abc7k2s' Index Vector NewVector ASCII filename 0 240faef0 128123792 'abc7' 'a' 0 240faef0 128123792 'abc7' 'ab' 0 240faef0 128123792 'abc7' 'abc' 0 240faef0 128123792 'abc7' 'abc7' 1 1234567a 243225 'k2s0' 'abc7k' 1 1234567a 243225 'k2s0' 'abc7k2' 1 1234567a 243225 'k2s0' 'abc7k2s' //EXIT LOOP// 1 1234567a 243225 'k2s0' 'abc7k2s' Here is the code that I've written so far to get filename (I'm just applying this to element 1000 of my DataMemory vector to test functionality. 1000 is arbitrary.): C++ Syntax (Toggle Plain Text) 1.int i = 0; 2.int step = 1000;//top->a0; 3.string filename; 4.char *temp = reinterpret_cast<char*>( DataMemory[1000] );//convert to char 5.cout << "a0:" << top->a0 << endl;//pointer supplied 6.cout << "Data:" << DataMemory[top->a0] << endl;//my vector at pointed to location 7.cout << "Data(1000):" << DataMemory[1000] << endl;//the element I'm testing 8.cout << "Characters:" << &temp << endl;//my temporary char array 9. 10.while(&temp[i]!=0) 11.{ 12. filename+=temp[i];//add most recent non-terminated character to string 13. i++; 14. if(i==4)//when 4 chatacters have been added.. 15. { 16. i=0; 17. step+=1;//restart loop at the next element in DataMemory 18. temp = reinterpret_cast<char*>( DataMemory[step] ); 19. } 20. } 21. cout << "Filename:" << filename << endl; int i = 0; int step = 1000;//top-a0; string filename; char *temp = reinterpret_cast( DataMemory[1000] );//convert to char cout << "a0:" << top-a0 << endl;//pointer supplied cout << "Data:" << DataMemory[top-a0] << endl;//my vector at pointed to location cout << "Data(1000):" << DataMemory[1000] << endl;//the element I'm testing cout << "Characters:" << &temp << endl;//my temporary char array while(&temp[i]!=0) { filename+=temp[i];//add most recent non-terminated character to string i++; if(i==3)//when 4 chatacters have been added.. { i=0; step+=1;//restart loop at the next element in DataMemory temp = reinterpret_cast( DataMemory[step] ); } } cout << "Filename:" << filename << endl; So the issue is that when I do the conversion of my decimal element to a char array I assume that 8 hex #'s will give me 4 characters. Why isn't this this case? Here is my output: C++ Syntax (Toggle Plain Text) 1.a0:0 2.Data:0 3.Data(1000):4428576 4.Characters:0x7fff5fbff128 5.Segmentation fault

• jqGrid concatinating/building html tag incorrectly

  - by Energetic Pixels

  Please excuse to length of post. But I needed to explain what I am seeing. I have a onSelectRow option that is supposed to build stacked html <li> tags (such as <li>...</li> <li>...</li> <li>...</li> ) up to the number of static xml elements that I am looking at. But my script is concatinating all the image src links together instead of building the whole listobject tag. Everything else in my jqGrid script works with exception of repeated elements inside my xml. onSelectRow: function() { var gsr = $('#searchResults').jqGrid('getGridParam', 'selrow'); if (gsr) { var data = $('#searchResults').jqGrid('getRowData', gsr); $('#thumbs ul').html('<li><a class='thumb' href='' + data.piclocation + '' title='' + data.pictitle + ''><img src='" + data.picthumb + "' alt='" + data.pictitle + "' /></a><div class='caption'><div class='image-title'>" + data.pictitle + "</div></div></li>"); };" my xml file is something like this: <photo> <pic> <asset>weaponLib/stillMedia/slides/A106.jpg</asset> <thumb>weaponLib/stillMedia/thumbs/A106.jpg</thumb> <caption>Side view of DODIC A106</caption> <title>Side view of 22 caliber long rifle ball cartridge</title> </pic> <pic> <asset>weaponLib/stillMedia/slides/A106_A.jpg</asset> <thumb>weaponLib/stillMedia/thumbs/A106_A.jpg</thumb> <caption>Side view of DODIC A106</caption> <title>Side view of 22 caliber long rifle ball cartridge</title> </pic> <pic> <asset>weaponLib/stillMedia/slides/A106_B.jpg</asset> <thumb>weaponLib/stillMedia/thumbs/A106_B.jpg</thumb> <caption>Side view of DODIC A106</caption> <title>Side view of 22 caliber long rifle ball cartridge</title> </pic> <pic> <asset>weaponLib/stillMedia/slides/A106_C.jpg</asset> <thumb>weaponLib/stillMedia/thumbs/A106_C.jpg</thumb> <caption>Side view of DODIC A106</caption> <title>Side view of 22 caliber long rifle ball cartridge</title> </pic> <pic> <asset>weaponLib/stillMedia/slides/A106_D.jpg</asset> <thumb>weaponLib/stillMedia/thumbs/A106_D.jpg</thumb> <caption>Side view of DODIC A106</caption> <title>Side view of 22 caliber long rifle ball cartridge</title> </pic> My script works fine when it only sees one sequence, but when it sees more than one it puts all html inside the tags together then for the caption and title does the same for them. It generates only one <li></li> tag set instead of 5 in the example above like I want. The <li> tags are being used by a slideshow (with thumbnails) utility. Inside firebug, I can see the object that it is built for me: <a title="Side view of 22 caliber long rifle ball cartridgeSide view of 22 caliber long rifle ball cartridgeSide view of 22 caliber long rifle ball cartridgeSide view of 22 caliber long rifle ball cartridgeSide view of 22 caliber long rifle ball cartridge" href="weaponLib/stillMedia/slides/A106.jpgweaponLib/stillMedia/slides/A106_A.jpgweaponLib/stillMedia/slides/A106_B.jpgweaponLib/stillMedia/slides/A106_C.jpgweaponLib/stillMedia/slides/A106_D.jpg" class="thumb"><img alt="Side view of 22 caliber long rifle ball cartridgeSide view of 22 caliber long rifle ball cartridgeSide view of 22 caliber long rifle ball cartridgeSide view of 22 caliber long rifle ball cartridgeSide view of 22 caliber long rifle ball cartridge" src="weaponLib/stillMedia/thumbs/A106.jpgweaponLib/stillMedia/thumbs/A106_A.jpgweaponLib/stillMedia/thumbs/A106_B.jpgweaponLib/stillMedia/thumbs/A106_C.jpgweaponLib/stillMedia/thumbs/A106_D.jpg"></a> Within jqGrid, the cell is holding: <td title="weaponLib/stillMedia/slides/A106.jpgweaponLib/stillMedia/slides/A106_A.jpgweaponLib/stillMedia/slides/A106_B.jpgweaponLib/stillMedia/slides/A106_C.jpgweaponLib/stillMedia/slides/A106_D.jpg" style="text-align: center; display: none;" role="gridcell">weaponLib/stillMedia/slides/A106.jpgweaponLib/stillMedia/slides/A106_A.jpgweaponLib/stillMedia/slides/A106_B.jpgweaponLib/stillMedia/slides/A106_C.jpgweaponLib/stillMedia/slides/A106_D.jpg</td> I know that jqGrid is building it wrong.

• Problem With View Helpers

  - by Richard Knop

  I wrote few custom view helpers but I have a little trouble using them. If I add the helper path in controller action like this: public function fooAction() { $this->view->addHelperPath('My/View/Helper', 'My_View_Helper'); } Then I can use the views from that path without a problem. But when I add the path in the bootstrap file like this: protected function _initView() { $this->view = new Zend_View(); $this->view->doctype('XHTML1_STRICT'); $this->view->headScript()->appendFile($this->view->baseUrl() . '/js/jquery-ui/jquery.js'); $this->view->headMeta()->appendHttpEquiv('Content-Type', 'text/html; charset=UTF-8'); $this->view->headMeta()->appendHttpEquiv('Content-Style-Type', 'text/css'); $this->view->headMeta()->appendHttpEquiv('Content-Language', 'sk'); $this->view->headLink()->appendStylesheet($this->view->baseUrl() . '/css/reset.css'); $this->view->addHelperPath('My/View/Helper', 'My_View_Helper'); } Then the view helpers don't work. Why is that? It's too troublesome to add the path in every controller action. Here is an example of how my custom view helpers look: class My_View_Helper_FooBar { public function fooBar() { return 'hello world'; } } I use them like this in views: <?php echo $this->fooBar(); ?> Should I post my whole bootstrap file? UPDATE: Added complete bootstrap file just in case: class Bootstrap extends Zend_Application_Bootstrap_Bootstrap { protected function _initFrontController() { $this->frontController = Zend_Controller_Front::getInstance(); $this->frontController->addModuleDirectory(APPLICATION_PATH . '/modules'); Zend_Controller_Action_HelperBroker::addPath( 'My/Controller/Action/Helper', 'My_Controller_Action_Helper' ); $this->frontController->registerPlugin(new My_Controller_Plugin_Auth()); $this->frontController->setBaseUrl('/'); } protected function _initView() { $this->view = new Zend_View(); $this->view->doctype('XHTML1_STRICT'); $this->view->headScript()->appendFile($this->view->baseUrl() . '/js/jquery-ui/jquery.js'); $this->view->headMeta()->appendHttpEquiv('Content-Type', 'text/html; charset=UTF-8'); $this->view->headMeta()->appendHttpEquiv('Content-Style-Type', 'text/css'); $this->view->headMeta()->appendHttpEquiv('Content-Language', 'sk'); $this->view->headLink()->appendStylesheet($this->view->baseUrl() .

• Java unit test coverage numbers do not match.

  - by Dan

  Below is a class I have written in a web application I am building using Java Google App Engine. I have written Unit Tests using TestNG and all the tests pass. I then run EclEmma in Eclipse to see the test coverage on my code. All the functions show 100% coverage but the file as a whole is showing about 27% coverage.

• Trying to create scrolling horizontal thumbnail navigation that hides on left side when not in use

  - by user346602

  Hi, I am trying recreate the following type of scrolling thumbnail navigation as described in the following tutorial: http://tympanus.net/codrops/2010/05/10/scrollable-thumbs-menu/ I require my thumbs to slide out horizontally from the left. I have amended the code to the best of my abilities, but I can't get it to work. (Think the problem is in the top third of the jquery). Here is what I have to date: HTML <ul class="menu" id="menu"> <li> <a href="#"></a> <div class="sc_menu_wrapper"> <div class="sc_menu"> <a href="#"><img src="images/gallery/1.jpg" alt=""/></a> <a href="#"><img src="images/gallery/2.jpg" alt=""/></a> <a href="#"><img src="images/gallery/3.jpg" alt=""/></a> <a href="#"><img src="images/gallery/4.jpg" alt=""/></a> <a href="#"><img src="images/gallery/5.jpg" alt=""/></a> </div> </div> </li> </ul> CSS /* Navigation Style */ ul.menu{ position: fixed; top: 0px; left:0px; width: 100%; } ul.menu li{ position:relative; width: 100% } ul.menu li > a{ position:absolute; top:300px; left:0px; width:40px; height:200px; background-color:#e7e7e8; } /* Thumb Scrolling Style */ div.sc_menu_wrapper { position: absolute; right: 0px; height: 220px; overflow: hidden; top: 300px; left:0px; visibility:hidden; } div.sc_menu { height: 200px; visibility:hidden; } .sc_menu a { display: block; background-color:#e7e7e8; } .sc_menu img { display: block; border: none; opacity:0.3; filter:progid:DXImageTransform.Microsoft.Alpha(opacity=30); } JQUERY $(function(){ // function to make the thumbs menu scrollable function buildThumbs($elem){ var $wrapper = $elem.next(); var $menu = $wrapper.find('.sc_menu'); var inactiveMargin = 220; // move the scroll down to the beggining (move as much as the height of the menu) $wrapper.scrollRight($menu.outerHeight()); //when moving the mouse up or down, the wrapper moves (scrolls) up or down $wrapper.bind('mousemove',function(e){ var wrapperWidth = $wrapper.width(); var menuWidth = $menu.outerWidth() + 2 * inactiveMargin; var top = (e.pageX - $wrapper.offset().right) * (menuWidth - wrapperWidth) / wrapperWidth - inactiveMargin; $wrapper.scrollRight(right+10); }); } var stacktime; $('#menu li > a').bind('mouseover',function () { var $this = $(this); buildThumbs($this); var pos = $this.next().find('a').size(); var f = function(){ if(pos==0) clearTimeout(stacktime); $this.next().find('a:nth-child('+pos+')').css('visibility','visible'); --pos; }; // each thumb will appear with a delay stacktime = setInterval(f , 50); }); /// on mouseleave of the whole <li> the scrollable area is hidden $('#menu li').bind('mouseleave',function () { var $this = $(this); clearTimeout(stacktime); $this.find('.sc_menu').css('visibility','hidden').find('a').css('visibility','hidden'); $this.find('.sc_menu_wrapper').css('visibility','hidden'); }); // when hovering a thumb, change its opacity $('.sc_menu a').hover( function () { var $this = $(this); $this.find('img') .stop() .animate({'opacity':'1.0'},400); }, function () { var $this = $(this); $this.find('img') .stop() .animate({'opacity':'0.3'},400); } ); }); Wondering if some eagle eye might be able to point out where I am going wrong. As my knowledge of JQuery is limited, I'm guessing it is in there. I really appreciate anyone taking the time to look this over. Thank you!

• How to programatically read native DLL imports in C#?

  - by Eric

  The large hunk of C# code below is intended to print the imports of a native DLL. I copied it from from this link and modified it very slightly, just to use LoadLibraryEx as Mike Woodring does here. I find that when I call the Foo.Test method with the original example's target, MSCOREE.DLL, it prints all the imports fine. But when I use other dlls like GDI32.DLL or WSOCK32.DLL the imports do not get printed. What's missing from this code that would let it print all the imports as, for example, DUMPBIN.EXE does? (Is there a hint I'm not grokking in the original comment that says, "using mscoree.dll as an example as it doesnt export any thing"?) Here's the extract that just shows how it's being invoked: public static void Test() { // WORKS: var path = @"c:\windows\system32\mscoree.dll"; // NO ERRORS, BUT NO IMPORTS PRINTED EITHER: //var path = @"c:\windows\system32\gdi32.dll"; //var path = @"c:\windows\system32\wsock32.dll"; var hLib = LoadLibraryEx(path, 0, DONT_RESOLVE_DLL_REFERENCES | LOAD_IGNORE_CODE_AUTHZ_LEVEL); TestImports(hLib, true); } And here is the whole code example: namespace PETest2 { [StructLayout(LayoutKind.Explicit)] public unsafe struct IMAGE_IMPORT_BY_NAME { [FieldOffset(0)] public ushort Hint; [FieldOffset(2)] public fixed char Name[1]; } [StructLayout(LayoutKind.Explicit)] public struct IMAGE_IMPORT_DESCRIPTOR { #region union /// <summary> /// CSharp doesnt really support unions, but they can be emulated by a field offset 0 /// </summary> [FieldOffset(0)] public uint Characteristics;

• another question about OpenGL ES rendering to texture

  - by ensoreus

  Hello, pros and gurus! Here is another question about rendering to texture. The whole stuff is all about saving texture between passing image into different filters. Maybe all iPhone developers knows about Apple's sample code with OpenGL processing where they used GL filters(functions), but pass into them the same source image. I need to edit an image by passing it sequentelly with saving the state of the image to edit. I am very noob in OpenGL, so I spent increadibly a lot of to solve the issue. So, I desided to create 2 FBO's and attach source image and temporary image as a textures to render in. Here is my init routine: glEnableClientState(GL_VERTEX_ARRAY); glEnableClientState(GL_TEXTURE_COORD_ARRAY); glEnable(GL_TEXTURE_2D); glPixelStorei(GL_UNPACK_ALIGNMENT, 1); glGetIntegerv(GL_FRAMEBUFFER_BINDING_OES, (GLint *)&SystemFBO); glImage = [self loadTexture:preparedImage]; //source image for (int i = 0; i < 4; i++) { fullquad[i].s *= glImage->s; fullquad[i].t *= glImage->t; flipquad[i].s *= glImage->s; flipquad[i].t *= glImage->t; } tmpImage = [self loadEmptyTexture]; //editing image glGenFramebuffersOES(1, &tmpImageFBO); glBindFramebufferOES(GL_FRAMEBUFFER_OES, tmpImageFBO); glFramebufferTexture2DOES(GL_FRAMEBUFFER_OES, GL_COLOR_ATTACHMENT0_OES, GL_TEXTURE_2D, tmpImage->texID, 0); GLenum status = glCheckFramebufferStatusOES(GL_FRAMEBUFFER_OES); if(status != GL_FRAMEBUFFER_COMPLETE_OES) { NSLog(@"failed to make complete tmp framebuffer object %x", status); } glBindTexture(GL_TEXTURE_2D, 0); glBindFramebufferOES(GL_FRAMEBUFFER_OES, 0); glGenRenderbuffersOES(1, &glImageFBO); glBindFramebufferOES(GL_FRAMEBUFFER_OES, glImageFBO); glFramebufferTexture2DOES(GL_FRAMEBUFFER_OES, GL_COLOR_ATTACHMENT0_OES, GL_TEXTURE_2D, glImage->texID, 0); status = glCheckFramebufferStatusOES(GL_FRAMEBUFFER_OES) ; if(status != GL_FRAMEBUFFER_COMPLETE_OES) { NSLog(@"failed to make complete cur framebuffer object %x", status); } glBindTexture(GL_TEXTURE_2D, 0); glBindFramebufferOES(GL_FRAMEBUFFER_OES, 0); When user drag the slider, this routine invokes to apply changes -(void)setContrast:(CGFloat)value{ contrast = value; if(flag!=mfContrast){ NSLog(@"contrast: dumped"); flag = mfContrast; glBindFramebufferOES(GL_FRAMEBUFFER_OES, glImageFBO); glClearColor(1,1,1,1); glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrthof(0, 512, 0, 512, -1, 1); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glScalef(512, 512, 1); glBindTexture(GL_TEXTURE_2D, tmpImage->texID); glViewport(0, 0, 512, 512); glVertexPointer(2, GL_FLOAT, sizeof(V2fT2f), &fullquad[0].x); glTexCoordPointer(2, GL_FLOAT, sizeof(V2fT2f), &fullquad[0].s); glDrawArrays(GL_TRIANGLE_STRIP, 0, 4); glBindFramebufferOES(GL_FRAMEBUFFER_OES, 0); } glBindFramebufferOES(GL_FRAMEBUFFER_OES,tmpImageFBO); glClearColor(0,0,0,1); glClear(GL_COLOR_BUFFER_BIT); glEnable(GL_TEXTURE_2D); glActiveTexture(GL_TEXTURE0); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrthof(0, 512, 0, 512, -1, 1); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glScalef(512, 512, 1); glBindTexture(GL_TEXTURE_2D, glImage->texID); glViewport(0, 0, 512, 512); [self contrastProc:fullquad value:contrast]; glBindFramebufferOES(GL_FRAMEBUFFER_OES, 0); [self redraw]; } Here are two cases: if it is the same filter(edit mode) to use, I bind tmpFBO to draw into tmpImage texture and edit glImage texture. contrastProc is a pure routine from Apples's sample. If it is another mode, than I save edited image by drawing tmpImage texture in source texture glImage, binded with glImageFBO. After that I call redraw: glBindFramebufferOES(GL_FRAMEBUFFER_OES, SystemFBO); glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrthof(0, kTexWidth, 0, kTexHeight, -1, 1); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glScalef(kTexWidth, kTexHeight, 1); glBindTexture(GL_TEXTURE_2D, glImage->texID); glViewport(0, 0, kTexWidth, kTexHeight); glVertexPointer(2, GL_FLOAT, sizeof(V2fT2f), &flipquad[0].x); glTexCoordPointer(2, GL_FLOAT, sizeof(V2fT2f), &flipquad[0].s); glDrawArrays(GL_TRIANGLE_STRIP, 0, 4); glBindFramebufferOES(GL_FRAMEBUFFER_OES, 0); And here it binds visual framebuffer and dispose glImage texture. So, the result is VERY aggresive filtering. Increasing contrast volume by just 0.2 brings image to state that comparable with 0.9 contrast volume in Apple's sample code project. I miss something obvious, I guess. Interesting, if I disabple line glBindTexture(GL_TEXTURE_2D, glImage->texID); in setContrast routine it brings no effect. At all. If I replace tmpImageFBO with SystemFBO to draw glImage directly on display(and disabling redraw invoking line), all works fine. Please, HELP ME!!! :(

• jQuery programming style?

  - by Sam Dufel

  I was recently asked to fix something on a site which I haven't worked on before. I haven't really worked with jQuery that much, but I figured I'd take a look and see if I could fix it. I've managed to mostly clear up the problem, but I'm still horrified at the way they chose to build this site. On document load, they replace the click() method of every anchor tag and form element with the same massive function. When clicked, that function then checks if the tag has one of a few different attributes (non-standard attributes, even), and does a variety of different tasks depending on what attributes exist and what their values are. Some hyperlinks have an attribute on them called 'ajaxrel', which makes the click() function look for another (hidden) hyperlink with an ID specified by the ajaxrel attribute, and then calls the click() function for that other hyperlink (which was also modified by this same click() function). On the server side, all the php files are quite long and have absolutely no indentation. This whole site has been a nightmare to debug. Is this standard jQuery practice? This navigation scheme seems terrible. Does anyone else actually use jQuery this way? I'd like to start incorporating it into my projects, but looking at this site is giving me a serious headache. Here's the click() function for hyperlinks: function ajaxBoxA(theElement, urltosend, ajaxbox, dialogbox) { if ($(theElement).attr("href") != undefined) var urltosend = $(theElement).attr("href"); if ($(theElement).attr('toajaxbox') != undefined) var ajaxbox = $(theElement).attr('toajaxbox'); // check to see if dialog box is called for. if ($(theElement).attr('dialogbox') != undefined) var dialogbox = $(theElement).attr('dialogbox'); var dodialog = 0; if (dialogbox != undefined) { // if dialogbox doesn't exist, then flag to create dialog box. var isDiaOpen = $('[ajaxbox="' + ajaxbox + '"]').parent().parent().is(".ui-dialog-container"); dodialog = 1; if (isDiaOpen) { dodialog = 0; } dialogbox = parseUri(dialogbox); dialogoptions = { close: function () { // $("[id^=hierarchy]",this).NestedSortableDestroy(); $(this).dialog('destroy').remove() } }; for ( var keyVar in dialogbox['queryKey'] ) eval( "dialogoptions." + keyVar + " = dialogbox['queryKey'][keyVar]"); }; $("body").append("<div id='TB_load'><img src='"+imgLoader.src+"' /></div>"); $('#TB_load').show(); if (urltosend.search(/\?/) > 0) { urltosend = urltosend + "&-ajax=1"; } else { urltosend = urltosend + "?-ajax=1"; } if ($('[ajaxbox="' + ajaxbox + '"]').length) { $('[ajaxbox="' + ajaxbox + '"]').each( function () { $(this).empty(); }); }; $.ajax({ type: "GET", url: urltosend, data: "", async: false, dataType: "html", success: function (html) { var re = /^<toajaxbox>(.*?)<\/toajaxbox>+(.*)/; if (re.test(html)) { var match = re.exec(html); ajaxbox = match[1]; html = Right(html, String(html).length - String(match[1]).length); } var re = /^<header>(.*?)<\/header>+(.*)/; if (re.test(html)) { var match = re.exec(html); window.location = match[1]; return false; } if (html.length > 0) { var newHtml = $(html); if ($('[ajaxbox="' + ajaxbox + '"]').length) { $('[ajaxbox="' + ajaxbox + '"]').each( function () { $(this).replaceWith(newHtml).ready( function () { ajaxBoxInit(newHtml) if (window.ajaxboxsuccess) ajaxboxsuccess(newHtml); }); }); if ($('[ajaxdialog="' + ajaxbox + '"]').length = 0) { if (dodialog) $(newHtml).wrap("<div class='flora ui-dialog-content' ajaxdialog='" + ajaxbox + "' style='overflow:auto;'></div>").parent().dialog(dialogoptions); } } else { $("body").append(newHtml).ready( function () { ajaxBoxInit(newHtml); if (window.ajaxboxsuccess) ajaxboxsuccess(newHtml); }); if (dodialog) $(newHtml).wrap("<div class='flora ui-dialog-content' ajaxdialog='" + ajaxbox + "' style='overflow:auto;'></div>").parent().dialog(dialogoptions); } } var rel = $(theElement).attr('ajaxtriggerrel'); if (rel != undefined) $('a[ajaxrel="' + rel + '"]').click(); tb_remove(); return false; }, complete: function () { $("#TB_load").remove(); } }); return false; }

• VB.NET - using textfile as source for menus and textboxes

  - by Kenny Bones

  Hi, this is probably a bit tense and I'm not sure if this is possible at all. But basically, I'm trying to create a small application which contains alot of PowerShell-code which I want to run in an easy matter. I've managed to create everything myself and it does work. But all of the PowerShell code is manually hardcoded and this gives me a huge disadvantage. What I was thinking was creating some sort of dynamic structure where I can read a couple of text files (possible a numerous amount of text files) and use these as the source for both the comboboxes and the richtextbox which provovides as the string used to run in PowerShell. I was thinking something like this: Combobox - "Choose cmdlet" - Use "menucode.txt" as source Richtextbox - Use "code.txt" as source But, the thing is, Powershell snippets need a few arguments in order for them to work. So I've got a couple of comboboxes and a few textboxes which provides as input for these arguments. And this is done manually as it is right now. So rewriting this small application should also search the textfile for some keywords and have the comboboxes and textboxes to replace those keywords. And I'm not sure how to do this. So, would this requre a whole lot of textfiles? Or could I use one textfile and separate each PowerShell cmdlet snippets with something? Like some sort of a header? Right now, I've got this code at the eventhandler (ComboBox_SelectedIndexChanged) If ComboBoxFunksjon.Text = "Set attribute" Then TxtBoxUsername.Visible = True End If If chkBoxTextfile.Checked = True Then If txtboxBrowse.Text = "" Then MsgBox("You haven't choses a textfile as input for usernames") End If LabelAttribute.Visible = True LabelUsername.Visible = False ComboBoxAttribute.Visible = True TxtBoxUsername.Visible = False txtBoxCode.Text = "$users = Get-Content " & txtboxBrowse.Text & vbCrLf & "foreach ($a in $users)" & vbCrLf & "{" & vbCrLf & "Set-QADUser -Identity $a -ObjectAttributes @{" & ComboBoxAttribute.SelectedItem & "='" & TxtBoxValue.Text & "'}" & vbCrLf & "}" If ComboBoxAttribute.SelectedItem = "Outlook WebAccess" Then TxtBoxValue.Visible = False CheckBoxValue.Visible = True CheckBoxValue.Text = "OWA Enabled?" txtBoxCode.Text = "$users = Get-Content " & txtboxBrowse.Text & vbCrLf & "foreach ($a in $users)" & vbCrLf & "{" & vbCrLf & "Set-CASMailbox -Identity $a -OWAEnabled" & " " & "$" & CheckBoxValue.Checked & " '}" & vbCrLf & "}" End If If ComboBoxAttribute.SelectedItem = "MobileSync" Then TxtBoxValue.Visible = False CheckBoxValue.Visible = True CheckBoxValue.Text = "MobileSync Enabled?" Dim value If CheckBoxValue.Checked = True Then value = "0" Else value = "7" End If txtBoxCode.Text = "$users = Get-Content " & txtboxBrowse.Text & vbCrLf & "foreach ($a in $users)" & vbCrLf & "{" & vbCrLf & "Set-QADUser -Identity $a -ObjectAttributes @{msExchOmaAdminWirelessEnable='" & value & " '}" & vbCrLf & "}" End If Else LabelAttribute.Visible = True LabelUsername.Visible = True ComboBoxAttribute.Visible = True txtBoxCode.Text = "Set-QADUser -Identity " & TxtBoxUsername.Text & " -ObjectAttributes @{" & ComboBoxAttribute.SelectedItem & "='" & TxtBoxValue.Text & " '}" If ComboBoxAttribute.SelectedItem = "Outlook WebAccess" Then TxtBoxValue.Visible = False CheckBoxValue.Visible = True CheckBoxValue.Text = "OWA Enabled?" txtBoxCode.Text = "Set-CASMailbox " & TxtBoxUsername.Text & " -OWAEnabled " & "$" & CheckBoxValue.Checked End If If ComboBoxAttribute.SelectedItem = "MobileSync" Then TxtBoxValue.Visible = False CheckBoxValue.Visible = True CheckBoxValue.Text = "MobileSync Enabled?" Dim value If CheckBoxValue.Checked = True Then value = "0" Else value = "7" End If txtBoxCode.Text = "Set-QADUser " & TxtBoxUsername.Text & " -ObjectAttributes @{msExchOmaAdminWirelessEnable='" & value & "'}" End If End If Now, this snippet above lets me either use a text file as a source for each username used in the powershell snippet. Just so you know :) And I know, this is probably coded as stupidly as it gets. But it does work! :)

• Problem creating calculations 'engine' in two class java calculator

  - by tokee

  i have hit a brick wall whilst attempting to create a two class java calculator but have been unsuccessful so far in getting it working. i have the code for an interface which works and displays ok but creating a seperate class 'CalcEngine' to do the actual calculations has proven to be beyond me. I'd appreciate it if someone could kick start things for me and create a class calcEngine which works with the interface class and allows input when from single button i.e. if one is pressed on the calc then 1 displays onscreen. please note i'm not asking someone to do the whole thing for me as i want to learn and i'm confident i can do the rest including addition subtraction etc. once i get over the obstacle of getting the two classes to communicate. any and all assistance would be very much appreciated.

• Saving image from Gallery to db - Coursor IllegalStateException

  - by MyWay

  I want to save to db some strings with image. Image can be taken from gallery or user can set the sample one. In the other activity I have a listview which should present the rows with image and name. I'm facing so long this problem. It occurs when I wanna display listview with the image from gallery, If the sample image is saved in the row everything works ok. My problem is similar to this one: how to save image taken from camera and show it to listview - crashes with "IllegalStateException" but I can't find there the solution for me My table in db looks like this: public static final String KEY_ID = "_id"; public static final String ID_DETAILS = "INTEGER PRIMARY KEY AUTOINCREMENT"; public static final int ID_COLUMN = 0; public static final String KEY_NAME = "name"; public static final String NAME_DETAILS = "TEXT NOT NULL"; public static final int NAME_COLUMN = 1; public static final String KEY_DESCRIPTION = "description"; public static final String DESCRIPTION_DETAILS = "TEXT"; public static final int DESCRIPTION_COLUMN = 2; public static final String KEY_IMAGE ="image" ; public static final String IMAGE_DETAILS = "BLOP"; public static final int IMAGE_COLUMN = 3; //method which create our table private static final String CREATE_PRODUCTLIST_IN_DB = "CREATE TABLE " + DB_TABLE + "( " + KEY_ID + " " + ID_DETAILS + ", " + KEY_NAME + " " + NAME_DETAILS + ", " + KEY_DESCRIPTION + " " + DESCRIPTION_DETAILS + ", " + KEY_IMAGE +" " + IMAGE_DETAILS + ");"; inserting statement: public long insertToProductList(String name, String description, byte[] image) { ContentValues value = new ContentValues(); // get the id of column and value value.put(KEY_NAME, name); value.put(KEY_DESCRIPTION, description); value.put(KEY_IMAGE, image); // put into db return db.insert(DB_TABLE, null, value); } Button which add the picture and onActivityResult method which saves the image and put it into the imageview public void AddPicture(View v) { // creating specified intent which have to get data Intent intent = new Intent(Intent.ACTION_PICK); // From where we want choose our pictures intent.setType("image/*"); startActivityForResult(intent, PICK_IMAGE); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { // TODO Auto-generated method stub super.onActivityResult(requestCode, resultCode, data); // if identification code match to the intent, //if yes we know that is our picture, if(requestCode ==PICK_IMAGE ) { // check if the data comes with intent if(data!= null) { Uri chosenImage = data.getData(); String[] filePathColumn = {MediaStore.Images.Media.DATA}; Cursor cursor = getContentResolver().query(chosenImage, filePathColumn, null, null, null); cursor.moveToFirst(); int columnIndex = cursor.getColumnIndex(filePathColumn[0]); String filePat = cursor.getString(columnIndex); cursor.close(); ImageOfProduct = BitmapFactory.decodeFile(filePat); if(ImageOfProduct!=null) { picture.setImageBitmap(ImageOfProduct); } messageDisplayer("got picture, isn't null " + IdOfPicture); } } } Then the code which converts bitmap to byte[] public byte[] bitmapToByteConvert(Bitmap bit ) { // stream of data getted for compressed bitmap ByteArrayOutputStream gettedData = new ByteArrayOutputStream(); // compressing method bit.compress(CompressFormat.PNG, 0, gettedData); // our byte array return gettedData.toByteArray(); } The method which put data to the row: byte[] image=null; // if the name isn't put to the editView if(name.getText().toString().trim().length()== 0) { messageDisplayer("At least you need to type name of product if you want add it to the DB "); } else{ String desc = description.getText().toString(); if(description.getText().toString().trim().length()==0) { messageDisplayer("the description is set as none"); desc = "none"; } DB.open(); if(ImageOfProduct!= null){ image = bitmapToByteConvert(ImageOfProduct); messageDisplayer("image isn't null"); } else { BitmapDrawable drawable = (BitmapDrawable) picture.getDrawable(); image = bitmapToByteConvert(drawable.getBitmap()); } if(image.length>0 && image!=null) { messageDisplayer(Integer.toString(image.length)); } DB.insertToProductList(name.getText().toString(), desc, image ); DB.close(); messageDisplayer("well done you add the product"); finish(); You can see that I'm checking here the length of array to be sure that I don't send empty one. And here is the place where Error appears imo, this code is from activity which presents the listview with data taken from db private void LoadOurLayoutListWithInfo() { // firstly wee need to open connection with db db= new sqliteDB(getApplicationContext()); db.open(); // creating our custom adaprer, the specification of it will be typed // in our own class (MyArrayAdapter) which will be created below ArrayAdapter<ProductFromTable> customAdapter = new MyArrayAdapter(); //get the info from whole table tablecursor = db.getAllColumns(); if(tablecursor != null) { startManagingCursor(tablecursor); tablecursor.moveToFirst(); } // now we moving all info from tablecursor to ourlist if(tablecursor != null && tablecursor.moveToFirst()) { do{ // taking info from row in table int id = tablecursor.getInt(sqliteDB.ID_COLUMN); String name= tablecursor.getString(sqliteDB.NAME_COLUMN); String description= tablecursor.getString(sqliteDB.DESCRIPTION_COLUMN); byte[] image= tablecursor.getBlob(3); tablefromDB.add(new ProductFromTable(id,name,description,image)); // moving until we didn't find last row }while(tablecursor.moveToNext()); } listView = (ListView) findViewById(R.id.tagwriter_listoftags); //as description says // setAdapter = The ListAdapter which is responsible for maintaining //the data backing this list and for producing a view to represent //an item in that data set. listView.setAdapter(customAdapter); } I put the info from row tho objects which are stored in list. I read tones of question but I can't find any solution for me. Everything works when I put the sample image ( which is stored in app res folder ). Thx for any advice

• How to manage maintenance/bug-fix branches in Subversion when third-party installers are involved?

  - by Mike Spross

  We have a suite of related products written in VB6, with some C# and VB.NET projects, and all the source is kept in a single Subversion repository. We haven't been using branches in Subversion (although we do tag releases now), and simply do all development in trunk, creating new releases when the trunk is stable enough. This causes no end of grief when we release a new version, issues are found with it, and we have already begun working on new features or major changes to the trunk. In the past, we would address this in one of two ways, depending on the severity of the issues and how stable we thought the trunk was: Hurry to stabilize the trunk, fix the issues, and then release a maintenance update based on the HEAD revision, but this had the side effect of releases that fixed the bugs but introduced new issues because of half-finished features or bugfixes that were in trunk. Make customers wait until the next official release, which is usually a few months. We want to change our policies to better deal with this situation. I was considering creating a "maintenance branch" in Subversion whenever I tag an official release. Then, new development would continue in trunk, and I can periodically merge specific fixes from trunk into the maintenance branch, and create a maintenance release when enough fixes are accumulated, while we continue to work on the next major update in parallel. I know we could also have a more stable trunk and create a branch for new updates instead, but keeping current development in trunk seems simpler to me. The major problem is that while we can easily branch the source code from a release tag and recompile it to get the binaries for that release, I'm not sure how to handle the setup and installer projects. We use QSetup to create all of our setup programs, and right now when we need to modify a setup project, we just edit the project file in-place (all the setup projects and any dependencies that we don't compile ourselves are stored on a separate server, and we make sure to always compile the setup projects on that machine only). However, since we may add or remove files to the setup as our code changes, there is no guarantee that today's setup projects will work with yesterday's source code. I was going to put all the QSetup projects in Subversion to deal with this, but I see some problems with this approach. I want the creation of setup programs to be as automated as possible, and at the very least, I want a separate build machine where I can build the release that I want (grabbing the code from Subversion first), grab the setup project for that release from Subversion, recompile the setup, and then copy the setup to another place on the network for QA testing and eventual release to customers. However, when someone needs to change a setup project (to add a new dependency that trunk now requires or to make other changes), there is a problem. If they treat it like a source file and check it out on their own machine to edit it, they won't be able to add files to the project unless they first copy the files they need to add to the build machine (so they are available to other developers), then copy all the other dependencies from the build machine to their machine, making sure to match the folder structure exactly. The issue here is that QSetup uses absolute paths for any files added to a setup project. However, this means installing a bunch of setup dependencies onto development machines, which seems messy (and which could destabilize the development environment if someone accidentally runs the setup project on their machine). Also, how do we manage third-party dependencies? For example, if the current maintenance branch used MSXML 3.0 and the trunk now requires MSXML 4.0, we can't go back and create a maintenance release if we have already replaced the MSXML library on the build machine with the latest version (assuming both versions have the same filename). The only solution I can think is to either put all the third-party dependencies in Subversion along with the source code, or to make sure we put different library versions in separate folders (i.e. C:\Setup\Dependencies\MSXML\v3.0 and C:\Setup\Dependencies\MSXML\v4.0). Is one way "better" or more common than the other? Are there any best practices for dealing with this situation? Basically, if we release v2.0 of our software, we want to be able to release v2.0.1, v2.0.2, and v.2.0.3 while we work on v2.1, but the whole setup/installation project and setup dependency issue is making this more complicated than the the typical "just create a branch in Subversion and recompile as needed" answer.

• List/Grid Toggle for Photo Gallery with Shadowbox

  - by InfamouslyBubbly

  so I'm new to this site, and new to jquery, and javascript as a whole really, but I have very good comprehension of HTML and CSS. For a class in school, I'm making a photo gallery webpage using the Shadowbox plugin. I have that part all down, but one of the requirements is to add some sort of user option that the user can change that will get saved in a cookie. (I haven't gotten to the cookie part yet) For my option, I decided to add a toggle that will switch the view of the page from a grid view (default) with images, to a list view of just the captions of the images. I figured out how to do that, but decided it could probably done in a much simpler fashion with the use of loops. Here is the HTML I have: <body> <div id="preferences"> <h1>My Photo Gallery</h1> <ul id="options"> <li><a href="#" id="list"><img src="media/listview.png" alt="List view"/></a></li> <li><a href="#" id="grid"><img src="media/gridview.png" alt="List view"/></a></li> </ul> </div> <div id="gallery"> <a rel="shadowbox[Gallery]" class="l1 img" href="media/img1.jpg" title="Black and White Leopard Pattern"><img src="media/thumb1.jpg" alt="Black and White Leopard Pattern"/></a> <a rel="shadowbox[Gallery]" class="l2 img" href="media/img2.jpg" title="Snow Leopard Pattern"><img src="media/thumb2.jpg" alt="Snow Leopard Pattern"/></a> <a rel="shadowbox[Gallery]" class="l3 img" href="media/img3.jpg" title="Colorful Triangle Pattern"><img src="media/thumb3.jpg" alt="Colurful Triangle Pattern"/></a> <a rel="shadowbox[Gallery]" class="l4 img" href="media/img4.jpg" title="Tie Dye Zebra Stripe Pattern"><img src="media/thumb4.jpg" alt="Tie Dye Zebra Stripe Pattern"/></a> <a rel="shadowbox[Gallery]" class="l5 img" href="media/img5.jpg" title="Blue Knitted Pattern"><img src="media/thumb5.jpg" alt="Blue Knitted Pattern"/></a> <a rel="shadowbox[Gallery]" class="l6 img" href="media/img6.jpg" title="Black and White Damask Pattern"><img src="media/thumb6.jpg" alt="Black and White Damask Pattern"/></a> <a rel="shadowbox[Gallery]" class="l7 img" href="media/img7.jpg" title="Wooden Panel Pattern"><img src="media/thumb7.jpg" alt="Wooden Panel Pattern"/></a> <a rel="shadowbox[Gallery]" class="l8 img" href="media/img8.jpg" title="Brick Pattern"><img src="media/thumb8.jpg" alt="Brick Pattern"/></a> <a rel="shadowbox[Gallery]" class="l9 img" href="media/img9.jpg" title="Watercolor Pattern"><img src="media/thumb9.jpg" alt="Watercolor Pattern"/></a> <a rel="shadowbox[Gallery]" class="l10 img" href="media/img10.jpg" title="Orange Stripe Pattern"><img src="media/thumb10.jpg" alt="Orange Stripe Pattern"/></a> <a rel="shadowbox[Gallery]" class="l11 img" href="media/img11.jpg" title="Blue Scales Pattern"><img src="media/thumb11.jpg" alt="Blue Scales Pattern"/></a> <a rel="shadowbox[Gallery]" class="l12 img" href="media/img12.jpg" title="Woven Pattern"><img src="media/thumb12.jpg" alt="Woven Pattern"/></a> </div> </body> So here is the sample that works (for the list portion anyways), but seems excessive in terms of code since I'd have to repeat for each image: $(document).ready(function(){ $( "#list" ).click(function() { $( "a.l1" ).removeClass( "img" ); $( "a.l1" ).addClass( "lst" ); $( "a.l1" ).text( $( "a.l1" ).attr( "title" ); //repeat for l1 through l12 (that`s the letter L not a 1) }); $( "#grid" ).click(function() { $( "a.l1" ).removeClass( "lst" ); $( "a.l1" ).addClass( "grid" ); //actually have no idea at all how to get this back to the original img tag other than maybe .innerHTML??? //repeat for l1 through l12 (again, that`s the letter L not a 1) }); }): And here is kinda how I'd like it (Y'know, except in a way that works) $(document).ready(function(){ var i = 1; var selcur = $( "'a.l" + i + "'" ); var title = selcur.attr( "title" ); var image = '<img src="media/thumb' + i + '.jpg" alt="' + title + '"/>'; $( "#list" ).click(function() { while (1<=12) { selcur.addClass("lst"); selcur.removeClass("img"); selcur.text( title ); i++; } i = 1; }); $( "#grid" ).click(function() { while (1<=12) { selcur.removeClass("lst"); selcur.addClass("img"); selcur.text( image ); i++; } i = 1; }); }); Please tell me how I am going about this wrong, keep in mind again I'm new to this, I appreciate any and all responses! Is there a better way to do this? I really want to keep it simple.

• Maven : Is it possible to override the configuration of a plugin already defined for a profile in a parent POM

  - by Guillaume Cernier

  In a POM parent file of my project, I have such a profile defining some configurations useful for this project (so that I can't get rid of this parent POM) : <profile> <id>wls7</id> ... <build> <plugins> <!-- use java 1.4 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <fork>true</fork> <source>1.4</source> <target>1.4</target> <meminitial>128m</meminitial> <maxmem>1024m</maxmem> <executable>%${jdk14.executable}</executable> </configuration> </plugin> </plugins> </build> ... </profile> But in my project I just would like to override the configuration of the maven-compiler-plugin in order to use jdk5 instead of jdk4 for compiling test-classes. That's why I did this section in the POM of my project : <profiles> <profile> <id>wls7</id> <activation> <property> <name>jdk</name> <value>4</value> </property> </activation> <build> <directory>target-1.4</directory> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <executions> <execution> <id>my-testCompile</id> <phase>test-compile</phase> <goals> <goal>testCompile</goal> </goals> <configuration> <fork>true</fork> <executable>${jdk15.executable}</executable> <compilerVersion>1.5</compilerVersion> <source>1.5</source> <target>1.5</target> <verbose>true</verbose> </configuration> </execution> </executions> </plugin> </plugins> </build> </profile> ... </profiles> and it's not working ... I even tried to override the configuration in regular plugin sections of my POM (I mean, not for a specific profile but for my whole POM). What could be the problem ? To clarify some of my requirements : I don't want to get rid of the parent POM and the profile (wls7) defined inside it (since I need many and many properties, configurations, ...) and that is not the process in my company. A solution based on duplicating the parent POM and/or the profile defined inside it is not a good one. Since if the responsible of the parent POM change something, I would have to report it in mine. It's just an inheritance matter (extend or override a profile, a configuration from an upper-level POM) so I think it should be possible with maven2.

• Linked lists in Java - Help with writing methods

  - by user368241

  Representation of a string in linked lists In every intersection in the list there will be 3 fields : The letter itself. The number of times it appears consecutively. A pointer to the next intersection in the list. The following class CharNode represents a intersection in the list : public class CharNode { private char _data; private int _value; private charNode _next; public CharNode (char c, int val, charNode n) { _data = c; _value = val; _next = n; } public charNode getNext() { return _next; } public void setNext (charNode node) { _next = node; } public int getValue() { return _value; } public void setValue (int v) { value = v; } public char getData() { return _data; } public void setData (char c) { _data = c; } } The class StringList represents the whole list : public class StringList { private charNode _head; public StringList() { _head = null; } public StringList (CharNode node) { _head = node; } } Add methods to the class StringList according to the details : (I will add methods gradually according to my specific questions) (Pay attention, these are methods from the class String and we want to fulfill them by the representation of a string by a list as explained above) Pay attention to all the possible error cases. Write what is the time complexity and space complexity of every method that you wrote. Make sure the methods you wrote are effective. It is NOT allowed to use ready classes of Java. It is NOT allowed to move to string and use string operations. 1) public int indexOf (int ch) - returns the index in the string it is operated on of the first appeareance of the char "ch". If the char "ch" doesn't appear in the string, returns -1. If the value of fromIndex isn't in the range, returns -1. Here is my try : public int indexOf (int ch) { int count = 0; charNode pos = _head; if (pos == null ) { return -1; } for (pos = _head; pos!=null && pos.getData()!=ch; pos = pos.getNext()) { count = count + pos.getValue(); } if (pos==null) return -1; return count; } Time complexity = O(N) Space complexity = O(1) EDIT : I have a problem. I tested it in BlueJ and if the char ch doesn't appear it returns -1 but if it does, it always returns 0 and I don't understand why... I am confused. How can the compiler know that the value is the number of times the letter appears consecutively? Can I assume this because its given on the question or what? If it's true and I can assume this, then my code should be correct right? Ok I just spoke with my instructor and she said it isn't required to write it in the exercise but in order for me to test that it indeed works, I need to open a new class and write a code for making a list so that the the value of every node is the number of times the letter appears consecutively. Can someone please assist me? So I will copy+paste to BlueJ and this way I will be able to test all the methods. Meanwhile I am moving on to the next methods. 2) public int indexOf (int ch, int fromIndex) - returns the index in the string it is operated on of the first appeareance of the char "ch", as the search begins in the index "fromIndex". If the char "ch" doesn't appear in the string, returns -1. If the value of fromIndex doesn't appear in the range, returns -1. Here is my try: public int indexOf (int ch, int fromIndex) { int count = 0, len=0, i; charNode pos = _head; CharNode cur = _head; for (pos = _head; pos!=null; pos = pos.getNext()) { len = len+1; } if (fromIndex<0 || fromIndex>=len) return -1; for (i=0; i<fromIndex; i++) { cur = cur.getNext(); } if (cur == null ) { return -1; } for (cur = _head; cur!=null && cur.getData()!=ch; cur = cur.getNext()) { count = count + cur.getValue(); } if (cur==null) return -1; return count; } Time complexity = O(N) ? Space complexity = O(1) 3) public StringList concat (String str) - returns a string that consists of the string that it is operated on and in its end the string "str" is concatenated. Here is my try : public StringList concat (String str) { String str = ""; charNode pos = _head; if (str == null) return -1; for (pos = _head; pos!=null; pos = pos.getNext()) { str = str + pos.getData(); } str = str + "str"; return str; } Time complexity = O(N) Space complexity = O(1)

• Object oriented n-tier design. Am I abstracting too much? Or not enough?

  - by max

  Hi guys, I'm building my first enterprise grade solution (at least I'm attempting to make it enterprise grade). I'm trying to follow best practice design patterns but am starting to worry that I might be going too far with abstraction. I'm trying to build my asp.net webforms (in C#) app as an n-tier application. I've created a Data Access Layer using an XSD strongly-typed dataset that interfaces with a SQL server backend. I access the DAL through some Business Layer Objects that I've created on a 1:1 basis to the datatables in the dataset (eg, a UsersBLL class for the Users datatable in the dataset). I'm doing checks inside the BLL to make sure that data passed to DAL is following the business rules of the application. That's all well and good. Where I'm getting stuck though is the point at which I connect the BLL to the presentation layer. For example, my UsersBLL class deals mostly with whole datatables, as it's interfacing with the DAL. Should I now create a separate "User" (Singular) class that maps out the properties of a single user, rather than multiple users? This way I don't have to do any searching through datatables in the presentation layer, as I could use the properties created in the User class. Or would it be better to somehow try to handle this inside the UsersBLL? Sorry if this sounds a little complicated... Below is the code from the UsersBLL: using System; using System.Data; using PedChallenge.DAL.PedDataSetTableAdapters; [System.ComponentModel.DataObject] public class UsersBLL { private UsersTableAdapter _UsersAdapter = null; protected UsersTableAdapter Adapter { get { if (_UsersAdapter == null) _UsersAdapter = new UsersTableAdapter(); return _UsersAdapter; } } [System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Select, true)] public PedChallenge.DAL.PedDataSet.UsersDataTable GetUsers() { return Adapter.GetUsers(); } [System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Select, false)] public PedChallenge.DAL.PedDataSet.UsersDataTable GetUserByUserID(int userID) { return Adapter.GetUserByUserID(userID); } [System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Select, false)] public PedChallenge.DAL.PedDataSet.UsersDataTable GetUsersByTeamID(int teamID) { return Adapter.GetUsersByTeamID(teamID); } [System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Select, false)] public PedChallenge.DAL.PedDataSet.UsersDataTable GetUsersByEmail(string Email) { return Adapter.GetUserByEmail(Email); } [System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Insert, true)] public bool AddUser(int? teamID, string FirstName, string LastName, string Email, string Role, int LocationID) { // Create a new UsersRow instance PedChallenge.DAL.PedDataSet.UsersDataTable Users = new PedChallenge.DAL.PedDataSet.UsersDataTable(); PedChallenge.DAL.PedDataSet.UsersRow user = Users.NewUsersRow(); if (UserExists(Users, Email) == true) return false; if (teamID == null) user.SetTeamIDNull(); else user.TeamID = teamID.Value; user.FirstName = FirstName; user.LastName = LastName; user.Email = Email; user.Role = Role; user.LocationID = LocationID; // Add the new user Users.AddUsersRow(user); int rowsAffected = Adapter.Update(Users); // Return true if precisely one row was inserted, // otherwise false return rowsAffected == 1; } [System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Update, true)] public bool UpdateUser(int userID, int? teamID, string FirstName, string LastName, string Email, string Role, int LocationID) { PedChallenge.DAL.PedDataSet.UsersDataTable Users = Adapter.GetUserByUserID(userID); if (Users.Count == 0) // no matching record found, return false return false; PedChallenge.DAL.PedDataSet.UsersRow user = Users[0]; if (teamID == null) user.SetTeamIDNull(); else user.TeamID = teamID.Value; user.FirstName = FirstName; user.LastName = LastName; user.Email = Email; user.Role = Role; user.LocationID = LocationID; // Update the product record int rowsAffected = Adapter.Update(user); // Return true if precisely one row was updated, // otherwise false return rowsAffected == 1; } [System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Delete, true)] public bool DeleteUser(int userID) { int rowsAffected = Adapter.Delete(userID); // Return true if precisely one row was deleted, // otherwise false return rowsAffected == 1; } private bool UserExists(PedChallenge.DAL.PedDataSet.UsersDataTable users, string email) { // Check if user email already exists foreach (PedChallenge.DAL.PedDataSet.UsersRow userRow in users) { if (userRow.Email == email) return true; } return false; } } Some guidance in the right direction would be greatly appreciated!! Thanks all! Max

• External Javascript file fails to receive variables from previous javascript block

  - by Franc

  I've been searching the net for several hours and can't find an answer in the whole "external js file"-jungle. I hope you guys can help! In short: My external javascript file doesn't seem to get the variables which I defined in the main.php file.. On main.php I define php variables and "transform" them into javascript variables <head>... <script type="text/javascript"> var phpmain_img = <?php echo json_encode($main_img); ?>; var phpvar1_large = <?php echo json_encode($var1_large); ?>; var phpvar2_large = <?php echo json_encode($var2_large); ?>; var phpvar3_large = <?php echo json_encode($var3_large); ?>; var phpvar4_large = <?php echo json_encode($var4_large); ?>; </script> ... <script language="javascript" type="text/javascript" src="/wshop/ext.js"></script> </head> In my ext.js file I want to process those variables. In the ext.js file I defined a the function swapImage() that will be used back in the main PHP: var imgArray = new Array( phpmain_img, phpvar1_large, phpvar2_large, phpvar3_large ); function swapImage(imgID) { var theImage = document.getElementById('theImage'); var newImg; newImg = imgArray[imgID]; theImage.src = newImg; } function preloadImages() { for(var i = 0; i < imgArray.length; i++) { var tmpImg = new Image; tmpImg.src = imgArray[i]; } } Result: The swapImage() in the main.php... doesnt work <div id="image"> <img id="theImage" src="<?=$main_img; ?>" alt="" /> </div> <div id="thumbs"> <?php echo "<img src=\"<$main_img_small\" alt=\"\" onmouseover=\"swapImage(0);\">"; echo "<img src=\"$var1_small\" alt=\"\" onmouseover=\"swapImage(1);\">"; echo "<img src=\"$var2_small\" alt=\"\" onmouseover=\"swapImage(2);\">"; echo "<img src=\"$var3_small\" alt=\"\" onmouseover=\"swapImage(3);\">"; ?> <br /> </div> Any help is greatly appreciated! UPDATE: I don't get a specific error, the swapImage functions doesn't work at mouseover. However, I tried to output the variables with e.g. document.write(phpimg_main) but nothing appears which makes me believe that there's something wrong with the handing over of the variables... here's the source code browser output `<html> <head> <link href="../demo.css" rel="stylesheet" type="text/css" /> <style type="text/css"> .... </style> <script type="text/javascript"> var phpmain_img = {"0":"http:\/\/path\/to\/main\/image.jpg"}; var phpvar1_large = {"0":"http:\/\/path\/to\/image1.jpg"}; var phpvar2_large = {"0":"http:\/\/path\/to\/image2.jpg"}; var phpvar3_large = null; var phpvar4_large = null; </script> <script language="javascript" type="text/javascript" src="/wshop/ext.js"></script> </head> <body onload="preloadImages()"> <div id="image"> <img id="theImage" src="http://path-to-main-image.jpg" alt="" /> </div> <div id="thumbs"> <img src="http://path-to-main-image.jpg" alt="" onmouseover="swapImage(0);"><img src="http://path-to-image1.jpg" alt="" onmouseover="swapImage(1);"><img src="http://path-to-image2.jpg" alt="" onmouseover="swapImage(2);"> <br /> </div> </body> `
