  • XNA - Inconsistent accessibility: parameter type is less accessible than method

    - by DijkeMark
    I have a level class in which I make a new turret. I give the turret the level class as parameter. So far so good. Then in the Update function of the Turret I call a function Shoot(), which has that level parameter it got at the moment I created it. But from that moment it gives the following error: Inconsistent accessibility: parameter type 'Space_Game.Level' is less accessible than method 'Space_Game.GameObject.Shoot(Space_Game.Level, string)' All I know it has something to do with not thr right protection level or something like that. The level class: public Level(Game game, Viewport viewport) { _game = game; _viewport = viewport; _turret = new Turret(_game, "blue", this); _turret.SetPosition((_viewport.Width / 2).ToString(), (_viewport.Height / 2).ToString()); } The Turret Class: public Turret(Game game, String team, Level level) :base(game) { _team = team; _level = level; switch (_team) { case "blue": _texture = LoadResources._blue_turret.Texture; _rows = LoadResources._blue_turret.Rows; _columns = LoadResources._blue_turret.Columns; _maxFrameCounter = 10; break; default: break; } _frameCounter = 0; _currentFrame = 0; _currentFrameMultiplier = 1; } public override void Update() { base.Update(); SetRotation(); Shoot(_level, "turret"); } The Shoot Function (Which is in GameObject class. The Turret Class inherited the GameObject Class. (Am I saying that right?)): protected void Shoot(Level level, String type) { MouseState mouse = Mouse.GetState(); if (mouse.LeftButton == ButtonState.Pressed) { switch (_team) { case "blue": switch (type) { case "turret": TurretBullet _turretBullet = new TurretBullet(_game, _team); level.AddProjectile(_turretBullet); break; default: break; } break; default: break; } } } Thanks in Advance, Mark Dijkema

  • JavaScript and callback nesting

    - by Jake King
    A lot of JavaScript libraries (notably jQuery) use chaining, which allows the reduction of this: var foo = $(".foo"); foo.stop(); foo.show(); foo.animate({ top: 0 }); to this: $(".foo").stop().show().animate({ top: 0 }); With proper formatting, I think this is quite a nice syntactic capability. However, I often see a pattern which I don't particularly like, but appears to be a necessary evil in non-blocking models. This is the ever-present nesting of callback functions: $(".foo").animate({ top: 0, }, { callback: function () { $.ajax({ url: 'ajax.php', }, { callback: function () { ... } }); } }); And it never ends. Even though I love the ease non-blocking models provide, I hate the odd nesting of function literals it forces upon the programmer. I'm interesting in writing a small JS library as an exercise, and I'd love to find a better way to do this, but I don't know how it could be done without feeling hacky. Are there any projects out there that have resolved this problem before? And if not, what are the alternatives to this ugly, meaningless code structure?

  • 2D Tile Collision free movement

    - by andrepcg
    I'm coding a 3D game for a project using OpenGL and I'm trying to do tile collision on a surface. The surface plane is split into a grid of 64x64 pixels and I can simply check if the (x,y) tile is empty or not. Besides having a grid for collision, there's still free movement inside a tile. For each entity, in the end of the update function I simply increase the position by the velocity: pos.x += v.x; pos.y += v.y; I already have a collision grid created but my collide function is not great, i'm not sure how to handle it. I can check if the collision occurs but the way I handle is terrible. int leftTile = repelBox.x / grid->cellSize; int topTile = repelBox.y / grid->cellSize; int rightTile = (repelBox.x + repelBox.w) / grid->cellSize; int bottomTile = (repelBox.y + repelBox.h) / grid->cellSize; for (int y = topTile; y <= bottomTile; ++y) { for (int x = leftTile; x <= rightTile; ++x) { if (grid->getCell(x, y) == BLOCKED){ Rect colBox = grid->getCellRectXY(x, y); Rect xAxis = Rect(pos.x - 20 / 2.0f, pos.y - 20 / 4.0f, 20, 10); Rect yAxis = Rect(pos.x - 20 / 4.0f, pos.y - 20 / 2.0f, 10, 20); if (colBox.Intersects(xAxis)) v.x *= -1; if (colBox.Intersects(yAxis)) v.y *= -1; } } } If instead of reversing the direction I set it to false then when the entity tries to get away from the wall it's still intersecting the tile and gets stuck on that position. EDIT: I've worked with Flashpunk and it has a great function for movement and collision called moveBy. Are there any simplified implementations out there so I can check them out?

  • Focusing and Selecting the Text in ASP.NET TextBox Controls

    When a browser displays the HTML sent from a web server it parses the received markup into a Document Object Model, or DOM, which models the markup as a hierarchical structure. Each element in the markup - the <form> element, <div> elements, <p> elements, <input> elements, and so on - are represented as a node in the DOM and can be programmatically accessed from client-side script. What's more, the nodes that make up the DOM have functions that can be called to perform certain behaviors; what functions are available depend on what type of element the node represents. One function common to most all node types is focus, which gives keyboard focus to the corresponding element. The focus function is commonly used in data entry forms, search pages, and login screens to put the user's keyboard cursor in a particular textbox when the web page loads so that the user can start typing in his search query or username without having to first click the textbox with his mouse. Another useful function is select, which is available for <input> and <textarea> elements and selects the contents of the textbox. This article shows how to call an HTML element's focus and select functions. We'll look at calling these functions directly from client-side script as well as how to call these functions from server-side code. Read on to learn more! Read More >

  • Running Outlook from VB with multiple email addresses [migrated]

    - by Mac
    I am sending emails from my VB6 system and I am having problems with sending a single email to various email addresses. The code is as follows: On Error Resume Next Err.Clear Set oOutLookObject = CreateObject("Outlook.Application") If Err <> 0 Then MsgBox "Email error. Err = " & Err & " Description = " & Err.Description EmailValid = "N" Exit Function End If Set oEmailItem = oOutLookObject.CreateItem(0) If Err <> 0 Then MsgBox "Email error. Err = " & Err & " Description = " & Err.Description EmailValid = "N" Exit Function End If With oEmailItem .Recipients.Add (SMRecipients) .Subject = SMSubject .Importance = IMPORTANCENORMAL .Body = SMBody For i = 1 To 10 If RTrim(SMAttach(i)) <> "" Then .attachments.Add SMAttach(1) 'i) Else Exit For End If Next i .send End With If Err <> 0 Then MsgBox "Email error. Err = " & Err & " Description = " & Err.Description EmailValid = "N" Exit Function End If ''' .Attachments.Add ("c:\temp\test2.txt") Set oOutLookObject = Nothing I have set SMRecipients to a single email address and it is fine but when I add more addresses seperated by semicolons or spaces it only sends to the original address. My system runs under XP. Another point is that it use to find the addresses in the Outlook Address book and where they wetre not specific enough it would display the matching addresses for selection of the correct one. It no longer does this.

  • Is this the correct approach to an OOP design structure in php?

    - by Silver89
    I'm converting a procedural based site to an OOP design to allow more easily manageable code in the future and so far have created the following structure: /classes /templates index.php With these classes: ConnectDB Games System User User -Moderator User -Administrator In the index.php file I have code that detects if any $_GET values are posted to determine on which page content to build (it's early so there's only one example and no default): function __autoload($className) { require "classes/".strtolower($className).".class.php"; } $db = new Connect; $db->connect(); $user = new User(); if(isset($_GET['gameId'])) { System::buildGame($gameId); } This then runs the BuildGame function in the system class which looks like the following and then uses gets in the Game Class to return values, such as $game->getTitle() in the template file template/play.php: function buildGame($gameId){ $game = new Game($gameId); $game->setRatio(900, 600); require 'templates/play.php'; } I also have .htaccess so that actual game page url works instead of passing the parameters to index.php Are there any major errors of how I'm setting this up or do I have the general idea of OOP correct?

  • How should I group these variables?

    - by stariz77
    I have a shape that will be defined by: char s_type; char color; double height; double width; These variables are scanned in from a request string sent to my server and passed into my printing function, which then prints out the shape. Currently they are just local variables sitting in my main(); however, I was wondering if there would be any advantage in creating a struct containing these variables, and then passing the struct to my printing function? or how else might I improve my program's structure/style, would passing a struct by reference have any kind of performance benefit if there were many requests and therefore many printing function calls? printer(char st, char cr, double ht, double wd); int main() { // Other main functionality. char s_type; char color; double height; double width; sscanf (serv_req, "GET /%c/%c/%lf/%lf", &s_type, &color, &height, &width); printer(s_type, color, height, width); // Other main functionality. return 0; } It seemed "neater" if I had a struct or something that didn't leave me with declarations in the middle of everything else going on in main. I'm interested in structure/style as well as performance. EDIT: didn't mean to put printer declaration inside main.

  • How to implement isValid correctly?

    - by Songo
    I'm trying to provide a mechanism for validating my object like this: class SomeObject { private $_inputString; private $_errors=array(); public function __construct($inputString) { $this->_inputString = $inputString; } public function getErrors() { return $this->_errors; } public function isValid() { $isValid = preg_match("/Some regular expression here/", $this->_inputString); if($isValid==0){ $this->_errors[]= 'Error was found in the input'; } return $isValid==1; } } Then when I'm testing my code I'm doing it like this: $obj = new SomeObject('an INVALID input string'); $isValid = $obj->isValid(); $errors=$obj->getErrors(); $this->assertFalse($isValid); $this->assertNotEmpty($errors); Now the test passes correctly, but I noticed a design problem here. What if the user called $obj->getErrors() before calling $obj->isValid()? The test will fail because the user has to validate the object first before checking the error resulting from validation. I think this way the user depends on a sequence of action to work properly which I think is a bad thing because it exposes the internal behaviour of the class. How do I solve this problem? Should I tell the user explicitly to validate first? Where do I mention that? Should I change the way I validate? Is there a better solution for this? UPDATE: I'm still developing the class so changes are easy and renaming functions and refactoring them is possible.

  • What gaming keyboard(s) will work with Ubuntu?

    - by belacqua
    I've been looking at gaming keyboards to use on Ubuntu system. Microsoft has a few popular ones (e.g., Sidewinder X4, X6), but the programmable function keys appear to be unusable without the Windows software. (Though here's a post from someone who has a more recent project that uses usbmon and xdotool to add functions to some keys.) Another choice in my budget is the Cyborg V.05. It seems about right for my needs, but I would be depressed having a bunch of useless, nonprogrammable keys on it. Logitech has some models (e.g., the Logitech G110), though again I expect that the extensive macro capabilities (which I don't need) would be lost under Linux. There's a project called g15tools which has some code to work with older Logitech gaming models, but I don't know what the current status is. Last entry there was in March 2010. There are also a number of very old posts around the internet with regard to the Logitech G11 and G15. Compatibility with the current keyboards, Ubuntu version, and Linux kernel are suspect. I'm in the U.S., and so it appears that few of the Roccat keyboards are available, and they're over-priced. Support might be OK for these, though -- there's a short Phoronix article about Roccat improving their Linux support, and there's also a project and webpage for "Using Roccat Hardware with Linux". Honestly, the only feature I have to have is good backlighting for the keys, and if it's not wired (which is fine), the wireless capability should function. I could probably live with dead function keys, as long as they weren't in places that would interfere with things like Unity/compiz shortcuts. Any experience or suggestions? I've not seen much to inspire confidence with programmable/macro keys. There is a thread (with no solutions) on the Sidewinder X4 on ubuntuforums here. I'm also considering the Logitech Illuminated Keyboard as a possibility, even though it's not specifically a gaming keyboard. It is backlit, and it's supposed to be a nice keyboard.

  • DB Object passing between classes singleton, static or other?

    - by Stephen
    So I'm designing a reporting system at work it's my first project written OOP and I'm stuck on the design choice for the DB class. Obviously I only want to create one instance of the DB class per-session/user and then pass it to each of the classes that need it. What I don't know it what's best practice for implementing this. Currently I have code like the following:- class db { private $user = 'USER'; private $pass = 'PASS'; private $tables = array( 'user','report', 'etc...'); function __construct(){ //SET UP CONNECTION AND TABLES } }; class report{ function __construct ($params = array(), $db, $user) { //Error checking/handling trimed //$db is the database object we created $this->db = $db; //$this->user is the user object for the logged in user $this->user = $user; $this->reportCreate(); } public function setPermission($permissionId = 1) { //Note the $this->db is this the best practise solution? $this->db->permission->find($permissionId) //Note the $this->user is this the best practise solution? $this->user->checkPermission(1) $data=array(); $this->db->reportpermission->insert($data) } };//end report I've been reading about using static classes and have just come across Singletons (though these appear to be passé already?) so what's current best practice for doing this?

  • What's the best way to use requestAnimationFrame and fixed frame rates

    - by m90
    I recently got into using the HTML5-requestAnimationFrame-API a lot on animation-heavy websites, especially after seeing the Jank Busters talk. This seems to work pretty well and really improve performance in many cases. Yet one question still persists for me: When wanting to use an animation that is NOT entirely calculated (think spritesheets for example) you will have to aim for a fixed frame rate. Of course one could go back to use setInterval again, but maybe there are other ways to tackle this. The two ways I could think of using requestAnimationFrame with a fixed frame rate are: var fps = 25; //frames per second function animate(){ //actual drawing goes here setTimeout(function(){ requestAnimationFrame(animate); }, 1000 / fps) } animate(); or var fps = 25; //frames per second var lastExecution = new Date().getTime(); function animate(){ var now = new Date().getTime(); if ((now - lastExecution) > (1000 / fps)){ //do actual drawing lastExecution = new Date().getTime(); } requestAnimationFrame(animate); } animate(); Personally, I'd opt for the second option (the first one feels like cheating), yet it seems to be more buggy in certain situations. Is this approach really worth it (especially at low frame rates like 12.5)? Are there things to be improved? Is there another way to tackle this?

  • Movement on the X an Z axis are combined?

    - by Magicaxis
    This is probably a stupid question, but I'm trying to simply move a 3D object up, down, left, and right (Not forward or backward). The Y axis works fine, but when I increment the object's X position, the object moves BOTH right and backwards! when I decrement X, left and forwards! setPosition(getPosition().X + 2/*times deltatime*/, getPosition().Y, getPosition().Z); I was astonished that XNA doesnt have its own setPosition function, so I made a parent class for all objects with a setPosition and Draw function. Setposition simply edits a variable "mPosition" and passes it to the common draw function: // Copy any parent transforms. Matrix[] transforms = new Matrix[block.Bones.Count]; block.CopyAbsoluteBoneTransformsTo(transforms); // Draw the model. A model can have multiple meshes, so loop. foreach (ModelMesh mesh in block.Meshes) { // This is where the mesh orientation is set, as well // as our camera and projection. foreach (BasicEffect effect in mesh.Effects) { effect.EnableDefaultLighting(); effect.World = transforms[mesh.ParentBone.Index] * Matrix.CreateRotationY(MathHelper.ToRadians(mOrientation.Y)) * Matrix.CreateTranslation(mPosition); effect.View = game1.getView(); effect.Projection = game1.getProjection(); } // Draw the mesh, using the effects set above. mesh.Draw(); } I tried to work it out by attempting to increment and decrement the Z axis, but nothing happens?! So using the X axis changes the objects x and z axis', but changing the Z does nothing. Great. So how do I seperate the X and Z axis movement?

  • how to override ckeditor events [migrated]

    - by joe
    I am new to ckeditor, I have hard time figuring this issue out. due to my html design; if I try to use the link editor dialog while my ckeditor is maximized, it just doesn't show up, I understand that ckeditor is the top most object in my html page and the link dialog comes underneath it. if now I bring ckeditor to its normal state I will be able to see and use the link dialog. my idea is to slightly override the link button click event as follows: if the editor is in full screen mode, bring it back to the normal state. and keep a flag somewhere so that when I close the link dialog, I can decide whether to bring back the ckeditor to a maximized mode again. now this is easy logic except that I do not know how to override the click event of the link button and keep it work as expected. here's what I have: $().ready(function () { var editor = $('#txa').ckeditor(); CKEDITOR.plugins.registered['link']= { init : function( editor ) { var command = editor.addCommand( 'link', { modes : { wysiwyg:1, source:1 }, exec : function( editor ) { if(editor.commands.maximize.state == 1 ){ alert("maximized"); //....here bring back the editor to UN-maximized state and let the link button event click do the default behavior } else { alert("normal state"); } //2 is normal state //1 is maximized } } ); editor.ui.addButton( 'link',{label : 'YOUR LABEL',command : 'link'}); } } }); html part to make the exemple work: <div> <textarea id="txa"> </textarea> </div> TO BE SHORT: http://jsfiddle.net/Q43QP/ if the editor is maximized, bring it to normal state then show the link dialog.

  • How to match responses from a server with their corresponding requests? [closed]

    - by Deele
    There is a server that responds to requests on a socket. The client has functions to emit requests and functions to handle responses from the server. The problem is that the request sending function and the response handling function are two unrelated functions. Given a server response X, how can I know whether it's a response to request X or some other request Y? I would like to make a construct that would ensure that response X is definitely the answer to request X and also to make a function requestX() that returns response X and not some other response Y. This question is mostly about the general programming approach and not about any specific language construct. Preferably, though, the answer would involve Ruby, TCP sockets, and PHP. My code so far: require 'socket' class TheConnection def initialize(config) @config = config end def send(s) toConsole("--> #{s}") @conn.send "#{s}\n", 0 end def connect() # Connect to the server begin @conn = TCPSocket.open(@config['server'], @config['port']) rescue Interrupt rescue Exception => detail toConsole('Exception: ' + detail.message()) print detail.backtrace.join('\n') retry end end def getSpecificAnswer(input) send "GET #{input}" end def handle_server_input(s) case s.strip when /^Hello. (.*)$/i toConsole "[ Server says hello ]" send "Hello to you too! #{$1}" else toConsole(s) end end def main_loop() while true ready = select([@conn, $stdin], nil, nil, nil) next if !ready for s in ready[0] if s == $stdin then return if $stdin.eof s = $stdin.gets send s elsif s == @conn then return if @conn.eof s = @conn.gets handle_server_input(s) end end end end def toConsole(msg) t = Time.new puts t.strftime("[%H:%M:%S]") + ' ' + msg end end @config = Hash[ 'server'=>'test.server.com', 'port'=>'2020' ] $conn = TheConnection.new(@config) $conn.connect() $conn.getSpecificAnswer('itemsX') begin $conn.main_loop() rescue Interrupt rescue Exception => detail $conn.toConsole('Exception: ' + detail.message()) print detail.backtrace.join('\n') retry end

  • "bug" in C++11 text by Stroustrup?

    - by Astara
    I found an apparent contradiction in the c++ text having to do with the result of the c_str() function operating on std:strings (in my copy, the definition and contradiction are on p1040). First it defines the c_str() function as something that produces a 'C-style' (zero-terminated) string, but later it talks about how a C++ c_str value can have embed a 'C'-style, end-of-string terminators (i.e. NUL's) embedded in the string (that is defined by being NUL terminated). Um... does anyone else feel that this is a 'stretching' of the definition of a C-string beyond it's definition? I.e. I think what it means, is that if you were to look at the length() function as applied to the string, it will show a different end of string than using the C-definition of a z-string -- one that can contain any character except NUL, and is terminated by NUL. I likely don't have to worry about it in my of my programs, but it seems like a subtle distinction that makes a C++ c_str, not really a 'C'-string. Am I misunderstanding this issue? Thanks!

  • Trying to implement pre/post method code: better to use methods or a parent class?

    - by Will
    I'm finding it difficult to frame this question so ... I want to execute code both before and after a method runs in PHP. There are, as far as I know, two ways to implement this: Method One: pre and post methods class Model { function find($id) { $this->_precode(); // ... do stuff $this->post_code(); } } Add the calls to _precode() and _postcode() to each method where I need this functionality. Method Two: __call and method naming class Model extends PrePost { function prepost_find($id) { // ... do stuff ... } } class PrePost { function __call($method,$param) { $method = "prepost_$method"; // .. precode here .. $result = $this->$method($param); // .. postcode here .. } } This relies on naming a method in a specific way in the inheriting class. Is there a preferred way of doing this? The call method can be made to only handle its specific cases and even defer to a child class's call if there is one. I'm not looking for opinions; I'm looking to find out if there are valid reasons to choose one way over another.

  • Collider2D and Rigidbody2D, how do they work?

    - by user42646
    I have been learning JavaScript and Unity for a week now. I learned how to make Cube as a Ground and another Cube as a player and I used this code to make the Player Cube move forward and backward and jumping var walkspeed: float = 5.0; var jumpheight: float = 250.0; var grounded = false; function Update() { rigidbody.freezeRotation = true; if (Input.GetKey("a")) transform.Translate(Vector3(-1, 0, 0) * Time.deltaTime * walkspeed); if (Input.GetKey("d")) transform.Translate(Vector3(1, 0, 0) * Time.deltaTime * walkspeed); if (Input.GetButton("Jump")) { Jump(); } } function OnCollisionEnter(hit: Collision) { grounded = true; } function Jump() { if (grounded == true) { rigidbody.AddForce(Vector3.up * jumpheight); grounded = false; } } I also learned how to make a character hit box. how to make a sprite and animation. pretty much the basic stuff. Couple of days ago I created simple ground in Photoshop and a simple character and imported them to Unity3D. Whenever I use my code above the character keeps falling from the scene. Like the character has nothing to stand on. After thinking about it it make sense because I really didn't make anything to make the player character understand that he should stand on something so I started reading about this issue and I realized that there is something called Collider2D and Rigidbody2D. Now I'm really stuck here I just don't know what to do. I applied the rigibody2d to my character picture and the Collider2D to the ground picture but whenever I play the project the gravity makes my character falls down. This is my question: How can I make the rigibody2d object realize that it shouldn't fall if there is a Collider2D object under it? So when I jump it's going to jump and the gravity going to bring it back to the ground.

  • How can I get the camera to follow a moving object from behind in C++ and openGL [closed]

    - by user1324894
    I am trying to get the camera to follow an object that moves around my environment using the gluLookAt function. This is my code for the object moving in the direction that it faces: Xtri += -Vtri*cos((90+heading)*(PI/180.0f)); Ztri += Vtri*sin((90+heading)*(PI/180.0f)); I then render the object: glPushMatrix(); glTranslatef(Xtri,0,Ztri); glRotatef(heading,0,1,0); drawTriangle(); glPopMatrix(); All heading is is a spin variable so that if I press left or right it spins in that direction. When you press up on the arrows it moves forward and if you press down it moves backwards in the direction that it is facing. To try and get it so the camera follows I am using the gluLookAt function like this: gluLookAt(Xtri,0,(Ztri+20), Xtri,0,Ztri, 0,1,0); So that it follows the car from a distance and should follow it around. However, the object doesn't even move at all now all it can do is rotate still but not move forwards or backwards and when it spins it doesn't follow the spin instead it just watches it turn still fixed to the same position. Where is it that I am going wrong? UPDATE: I have updated the gluLookAt function so now it is: gluLookAt((Xtri+Vtri),0,((Ztri+20)), (Xtri+Vtri),0,(Ztri), 0,1,0); This seems to move the object around. I have a stationary terrain so I can see that the object is now moving and in the direction that it is facing. However, I want the camera to follow the object when it spins as well so it is always viewing the object from behind.

  • Simple jquery ajax call leaks memory in ie.

    - by Thomas Lane
    I created a web page that makes an ajax call every second. In Internet Explorer 7, it leaks memory badly (20MB in about 15 minutes). The program is very simple. It just runs a javascript function that makes an ajax call. The server returns an empty string, and the javascript does nothing with it. I use setTimout to run the function every second, and I'm using Drip to watch the thing. Here is the source: <html> <head> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load('jquery', '1.4.2'); google.load('jqueryui', '1.7.2'); </script> <script type="text/javascript"> setTimeout('testJunk()',1000); function testJunk() { $.ajax({ url: 'http://xxxxxxxxxxxxxx/test', // The url returns an empty string dataType: 'html', success: function(data){} }); setTimeout('testJunk()',1000) } </script> </head> <body> Why is memory usage going up? </body> </html> Anyone have an idea how to plug this leak? I have a real application that updates a large table this way, but left unattended will eat up Gigabytes of memory. Okay, so after some good suggestions, I modified the code to: <html> <head> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load('jquery', '1.4.2'); google.load('jqueryui', '1.7.2'); </script> <script type="text/javascript"> setTimeout(testJunk,1000); function testJunk() { $.ajax({ url: 'http://xxxxxxxxxxxxxx/test', // The url returns an empty string dataType: 'html', success: function(data){setTimeout(testJunk,1000)} }); } </script> </head> <body> Why is memory usage going up? </body> </html> It didn't seem to make any difference though. I'm not doing anything with the DOM, and if I comment out the ajax call, the memory leak stops. So it looks like the leak is entirely in the ajax call. Does jquery ajax inherently create some sort of circular reference, and if so, how can I free it? By the way, it doesn't leak in Firefox. Someone suggested running the test in another VM and see if the results are the same. Rather than setting up another VM, I found a laptop that was running XP Home with IE8. It exhibits the same problem. I tried some older versions of jquery and got better results, but the problem didn't go away entirely until I abandoned ajax in jquery and went with more traditional (and ugly) ajax.

  • selectLimit in JQgrid

    - by Leander
    Hallo, I have a problem. I'am trying to get some data from my database. But with a limit. So i use the selectLimit command. But when i load the grid my firebug gives the following error: "parsererror"?e:null},parse:function(d...d(a.fn.jqGrid,d);this.no_legacy_api|| When I go to the selectLimit in the jqgrid.php and print out what the function returns it normaly return an array with all 500 objects with the correct data. This is the code of the grid: <?php require_once ($_SERVER['DOCUMENT_ROOT'].'/includes_config/config.inc.php'); require_once ($_SERVER['DOCUMENT_ROOT'].'/portal/classes/core/database/class_Database_control.php'); $dtb = new clsDatabaseControl(); $dtb = $dtb->getDatabase(ConnectionString); $dtb->doConnect(); require_once (ClassRoot.'/3rd/jqgrid/jq-config.php'); require_once (ClassRoot.'/3rd/jqgrid/php/jqGrid.php'); require_once (ClassRoot.'/3rd/jqgrid/php/jqGridPdo.php'); //require_once (ClassRoot.'/modules/logging/class_logging_control.php'); // //$oLogginControl = new clsLoggingControl($dtb); //$sSQL = $oLogginControl->getAanmeldingenGrid(); $sSQL = "SELECT LogAanmeldID, LogAanmeldStamp, UserFirstName, UserLastName, LogAanmeldIP, LogAanmeldMethod, LogAanmeldHost, LogAanmeldAgent FROM log_aanmelden, user WHERE log_aanmelden.LogAanmeldUserID = user.UserID"; $conn = new PDO(DB_DSN,DB_USER,DB_PASSWORD); $conn->query("SET NAMES utf8"); $grid = new jqGridRender($conn); //$grid->SelectCommand = $sSQL; $grid->selectLimit($sSQL ,500,1); $grid->dataType = 'json'; $grid->setColModel(); $grid->setUrl('modules/module_logging/index.php?grid=2'); $grid->setGridOptions(array( "hoverrows"=>true, //"sortname"=>"naam", "height"=>450 )); // Enable toolbar searching $grid->toolbarfilter = true; $grid->setFilterOptions(array("stringResult"=>true)); $grid->navigator = true; $grid->setNavOptions('navigator', array("excel"=>true,"add"=>false,"edit"=>false,"del"=>false,"view"=>true, "refresh"=>false)); $custom = <<<CUSTOM $(document).ready(function() { gridParentWidth = $(window).width(); $('#grid').jqGrid('setGridWidth',gridParentWidth-10); }) $(window).resize(function() { gridParentWidth = $(window).width(); $('#grid').jqGrid('setGridWidth',gridParentWidth-10); }); function formatAddAdresboek(cellValue, options, rowObject) { var imageHtml = "<a href='?FFID=51000&TID=1&INS=3&contactID=" + cellValue + "' originalValue='" + cellValue + "'><img border='0' alt='Toevoegen aan Persoonlijk Adresboek' src='images/16X16/new_user.gif'/></a>"; imageHtml = imageHtml + " <a href='?FFID=51000&TID=2&INS=3&contactID=" + cellValue + "' originalValue='" + cellValue + "'><img border='0' alt='Toevoegen aan Praktijk Adresboek' src='images/16X16/new_usergroup.gif'/></a>"; return imageHtml; } function unformatAddAdresboek(cellValue, options, cellObject) { return $(cellObject.html()).attr("originalValue"); } CUSTOM; $grid->setJSCode($custom); // Enjoy $grid->renderGrid('#grid','#pager',true, null, null, true,true); $conn = null; ?> When I inspect the $_GET the answer is empty and in stead of a JSON tab there is an HTML tab. When i use the selectCommand in stead of the selectLimit it return all the data correct as an json object an parses it correcly in the grid but it doens't use the LIMIT, Because when i add the limit. PDO doens't work anymore. So how do I get the object from the selectLimit to the grid? Can someone please help me get the grid working?

  • postMessage to PDF in an iFrame

    - by Linus
    Here's my situation. I had a webpage with an embedded PDF form. We used a basic object tag (embed in FF) to load the PDF file like this: <object id="pdfForm" height="100%" width="100%" type="application/pdf" data="..url"></object> On this webpage was an Html Save button that would trigger some Javascript which used the postMessage API of the embedded object to execute javascript embedded in the PDF. Basically, that code looked like this: function save() { sendMessage(["submitForm"]); } function sendMessage(aMessage) { pdfObject = document.getElementById("pdfForm"); if (typeof(pdfObject) == "undefined") return; if (typeof (pdfObject.postMessage) == "undefined") return; pdfObject.postMessage(aMessage); } This all was working beautifully. Except we ran into an issue with Firefox so that we need to embed the PDF using iFrame, instead of the object tag. So now, the PDF is embeded using this code: <iframe id="pdfWrapper" src="..someUrl" width="100%" height="800px" frameborder="0"></iframe> Unfortunately, with this code, the javascript for posting a message no longer works, and I can't really figure out how to get access to the pdf object anymore so that I can access the postMessage api. Using fiddler or the chome javascript debugger, it is clear that within the iframe, the browser is automatically generating an embed tag (not an object tag), but that does not let me access the postMessage API. This is the code I'm trying which doesn't work: function sendMessage(aMessage) { var frame = document.getElementById("pdfWrapper"); var doc = null; if (frame.contentDocument) doc = frame.contentDocument; else if (frame.contentWindow) doc = frame.contentWindow.document; else if (frame.document) doc = frame.document; if (doc==null || typeof(doc) == "undefined") return; var pdfObject = doc.embeds[0]; if (pdfObject==null || typeof (pdfObject.postMessage) == "undefined") return; pdfObject.postMessage(aMessage); } Any help on this? Sorry for the long question. EDIT: I've been asked to provide samples in code so that people can test whether the messaging works. Essentially, all you need is any PDF with this javascript embedded. function myOnMessage(aMessage) { app.alert("Hello World!"); } function myOnDisclose(cURL, cDocumentURL) { return true; } function myOnError(error, aMessage) { app.alert(error); } var msgHandlerObject = new Object(); msgHandlerObject.onMessage = myOnMessage; msgHandlerObject.onError = myOnError; msgHandlerObject.onDisclose = myOnDisclose; msgHandlerObject.myDoc = this; this.hostContainer.messageHandler = msgHandlerObject; I realize you need Acrobat pro to create PDFs with javascript, so to make this easier, I posted sample code--both working and non working scenarios--at this url: http://www.filedropper.com/pdfmessage You can download the zip and extract it to /inetpub/wwwroot if you use Windows, and then point your browser to either the works.htm or fails.htm. Thanks for any help you can give.

  • Dojox grid having problem with Contentpane

    - by ice
    the grid appears properly on template's first loading. But when you click the paging button to load flooders.php thru list_result1() only the paging buttons will appear. I already tested the flooders.php outside the template and it works properly. what seems to be the problem? and what are the tools that i can use to see if the javascript is loading properly because i think the error console of ff browser which i use to track errors won't give you that much info when you are working with contentpane. thanks! ice note: below are the codes... ** from contentpane js function list_result1(){ args=""; uri = "flooders.php" + args; dojo.xhrGet( { url: uri, handleAs: "text", timeout: 500, // Time in milliseconds load: function(response, ioArgs) { //alert(response); dojo.byId("flooders_table").innerHTML = response; return response; }, // The ERROR function will be called in an error case. error: function(response, ioArgs) { console.error("HTTP status code: ", ioArgs.xhr.status); return response; } }); //end of dojo.xhrGet } **flooders.php starts here*** @import "js/dojo-0.9.0/dojo/resources/dojo.css"; @import "js/dojo-0.9.0/dijit/themes/tundra/tundra.css"; @import "js/dojo-0.9.0/dijit/themes/tundra/tundra_rtl.css"; @import "css/ash.css"; @import "js/dojo-0.9.0/dojox/grid/resources/Grid.css"; @import "js/dojo-0.9.0/dojox/grid/resources/tundraGrid.css"; @import "js/dojo-0.9.0/dojo/resources/dojo.css"; @import "js/dojo-0.9.0/dijit/tests/css/dijitTests.css"; .dojoxGridRowEditing td { background-color: #F4FFF4; } .dojoxGrid input, .dojoxGrid select, .dojoxGrid textarea { margin: 0; padding: 0; border-style: none; width: 100%; font-size: 100%; font-family: inherit; } .dojoxGrid input { } .dojoxGrid select { } .dojoxGrid textarea { } #controls { padding: 0px 0; } #controls button { margin-left: 10px; } .myGrid { width: 550px; height: 230px; margin-left: 20px; /* border: 1px solid silver; */ } echo " // it has script heading here (function(){ // some sample data // global var 'data' data = { identifier: 'id', label: 'id', items: [] }; data_list = [ $banlist ]; var rows = $listnum ; var x=1; for(var i=0, l=data_list.length; i // global var 'test_store' test_store = new dojo.data.ItemFileWriteStore({data: data}); })(); // it has ending here "; ?   -- here's the javascript dojo.require("dijit.TitlePane"); dojo.require("dijit.dijit"); dojo.require("dojox.grid.DataGrid"); dojo.require("dojo.data.ItemFileWriteStore"); dojo.require("dojo.parser"); // scan page for widgets and instantiate them dojo.require("dijit.layout.LayoutContainer"); dojo.require("dijit.layout.AccordionContainer"); dojo.require("dijit.layout.ContentPane"); dojo.require("dijit.layout.TabContainer"); dojo.require("dijit.Editor"); dojo.require("dijit._editor.plugins.AlwaysShowToolbar"); dojo.require("dijit._editor.plugins.LinkDialog"); //this must be inlcuded below function() selectCell = { styles: 'text-align: center;', type: dojox.grid.cells.Select }; gridLayout = { defaultCell: { width: 5, styles: 'text-align: right;' }, rows: [ [ { name: 'Mark', width: 3, field: 'col1', editable: true, styles: 'text-align: center;', type: dojox.grid.cells.Bool }, { name: 'Id', width: 3, field: 'id' , editable: false }, { name: 'Username', field: 'col2', editable: false, styles: '', width: '70%' }, { name: 'Reason', field: 'col3', editable: false , styles: '', width: '100%' }, { name: 'Date Banned', field: 'col4', editable: false , styles: '', width: '70%' } ] ] };

  • Entity Framework many-to-many using VB.Net Lambda

    - by bgs264
    Hello, I'm a newbie to StackOverflow so please be kind ;) I'm using Entity Framework in Visual Studio 2010 Beta 2 (.NET framework 4.0 Beta 2). I have created an entity framework .edmx model from my database and I have a handful of many-to-many relationships. A trivial example of my database schema is Roles (ID, Name, Active) Members (ID, DateOfBirth, DateCreated) RoleMembership(RoleID, MemberID) I am now writing the custom role provider (Inheriting System.Configuration.Provider.RoleProvider) and have come to write the implementation of IsUserInRole(username, roleName). The LINQ-to-Entity queries which I wrote, when SQL-Profiled, all produced CROSS JOIN statements when what I want is for them to INNER JOIN. Dim query = From m In dc.Members From r In dc.Roles Where m.ID = 100 And r.Name = "Member" Select m My problem is almost exactly described here: http://stackoverflow.com/questions/553918/entity-framework-and-many-to-many-queries-unusable I'm sure that the solution presented there works well, but whilst I studied Java at uni and I can mostly understand C# I cannot understand this Lambda syntax provided and I need to get a similar example in VB. I've looked around the web for the best part of half a day but I'm not closer to my answer. So please can somebody advise how, in VB, I can construct a LINQ statement which would do this equivalent in SQL: SELECT rm.RoleID FROM RoleMembership rm INNER JOIN Roles r ON r.ID = rm.RoleID INNER JOIN Members m ON m.ID = rm.MemberID WHERE r.Name = 'Member' AND m.ID = 101 I would use this query to see if Member 101 is in Role 3. (I appreciate I probably don't need the join to the Members table in SQL but I imagine in LINQ I'd need to bring in the Member object?) UPDATE: I'm a bit closer by using multiple methods: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim count As Integer Using dc As New CBLModel.CBLEntities Dim persons = dc.Members.Where(AddressOf myTest) count = persons.Count End Using System.Diagnostics.Debugger.Break() End Sub Function myTest(ByVal m As Member) As Boolean Return m.ID = "100" AndAlso m.Roles.Select(AddressOf myRoleTest).Count > 0 End Function Function myRoleTest(ByVal r As Role) As Boolean Return r.Name = "Member" End Function SQL Profiler shows this: SQL:BatchStarting SELECT [Extent1].[ID] AS [ID], ... (all columns from Members snipped for brevity) ... FROM [dbo].[Members] AS [Extent1] RPC:Completed exec sp_executesql N'SELECT [Extent2].[ID] AS [ID], [Extent2].[Name] AS [Name], [Extent2].[Active] AS [Active] FROM [dbo].[RoleMembership] AS [Extent1] INNER JOIN [dbo].[Roles] AS [Extent2] ON [Extent1].[RoleID] = [Extent2].[ID] WHERE [Extent1].[MemberID] = @EntityKeyValue1',N'@EntityKeyValue1 int',@EntityKeyValue1=100 SQL:BatchCompleted SELECT [Extent1].[ID] AS [ID], ... (all columns from Members snipped for brevity) ... FROM [dbo].[Members] AS [Extent1] I'm not certain why it is using sp_execsql for the inner join statement and why it's still running a select to select ALL members though. Thanks. UPDATE 2 I've written it by turning the above "multiple methods" into lambda expressions then all into one query, like this: Dim allIDs As String = String.Empty Using dc As New CBLModel.CBLEntities For Each retM In dc.Members.Where(Function(m As Member) m.ID = 100 AndAlso m.Roles.Select(Function(r As Role) r.Name = "Doctor").Count > 0) allIDs &= retM.ID.ToString & ";" Next End Using But it doesn't seem to work: "Doctor" is not a role that exists, I just put it in there for testing purposes, yet "allIDs" still gets set to "100;" The SQL in SQL Profiler this time looks like this: SELECT [Project1].* FROM ( SELECT [Extent1].*, (SELECT COUNT(1) AS [A1] FROM [dbo].[RoleMembership] AS [Extent2] WHERE [Extent1].[ID] = [Extent2].[MemberID]) AS [C1] FROM [dbo].[Members] AS [Extent1] ) AS [Project1] WHERE (100 = [Project1].[ID]) AND ([Project1].[C1] > 0) For brevity I turned the list of all the columns from the Members table into * As you can see it's just ignoring the "Role" query... :/

  • How to remove buttons in AnythingSlider and stop the sliding?

    - by user244394
    I'm currently using the anythingSlider it works quite well. But if there is one li, how do i make it stop sliding and remove the buttons displayed below? The *li*s are generated from the database so sometimes there's only one. I want the buttons to show only when there is more then one image. if there is one image all the buttons( back, forward, pause) should not be displayed. Does anybody know of a way of stopping it sliding if there's only one li and removing the buttons when there is only one image. ===================================================================================== Thank You. Currently I have the working version, posted below the old code is working. I tried to replace it with yours it didnt seem to work. Is there something else that needs to be added? function formatText(index, panel) { return index + ""; } $(function () { $('.anythingSlider').anythingSlider({ easing: "easeInOutExpo", // Anything other than "linear" or "swing" requires the easing plugin autoPlay: true, // This turns off the entire FUNCTIONALY, not just if it starts running or not. delay: 7500, // How long between slide transitions in AutoPlay mode startStopped: false, // If autoPlay is on, this can force it to start stopped animationTime: 1250, // How long the slide transition takes hashTags: true, // Should links change the hashtag in the URL? buildNavigation: true, // If true, builds and list of anchor links to link to each slide pauseOnHover: true, // If true, and autoPlay is enabled, the show will pause on hover startText: "", // Start text stopText: "", // Start text navigationFormatter: formatText // Details at the top of the file on this use (advanced use) }); $("#slide-jump").click(function(){ $('.anythingSlider').anythingSlider(6); }); }); UPDATED WITH YOUR CODE : function formatText(index, panel) { return index + ""; } $(function () { var singleSlide = true, options = { autoPlay: false, // This turns off the entire FUNCTIONALY, not just if it starts running or not. buildNavigation: false, // If true, builds and list of anchor links to link to each slide easing: "easeInOutExpo", // Anything other than "linear" or "swing" requires the easing plugin delay: 3000, // How long between slide transitions in AutoPlay mode animationTime: 600, // How long the slide transition takes hashTags: true, // Should links change the hashtag in the URL? pauseOnHover: true, // If true, and autoPlay is enabled, the show will pause on hover navigationFormatter: formatText // Details at the top of the file on this use (advanced use) }; // Add player options if more than one slide exists if ( $('.anythingSlider div ul li').length 1 ) { $.extend(options, { autoPlay: true, startStopped: false, // If autoPlay is on, this can force it to start stopped startText: "", // Start text stopText: "", // Start text buildNavigation: true }); singleSlide = false; } // Initiate anythingSlider $("#slide-jump").click(function(){ $('.anythingSlider').anythingSlider(6); }); // hide anythingSlider navigation arrows if (singleSlide) { $('.anythingSlider a.arrow').hide(); } }); HTML TAGS ========================================================================================= Update May 25 ,2010 When using $('.anythingSlider').anythingSlider(options); instead of $('.anythingSlider').anythingSlider(6); the slider runs but I noticed that I get a Javascript Error :Object required is there anything else I need to pass? Since before anythingSlider was taking 6 instead of options, where do I pass that 6, since its looking for it.
