  • php, mySQL & AJAX: Unable to use sessions across the scripts in the same domain

    - by Devner
    Hi all, I have the following pages: page1.php, page2.php and page3.php. Code in each of them is as below CODE: page1.php <script type="text/javascript"> $(function(){ $('#imgID').upload({ submit_to_url: "page2.php", file_name: 'myfile1', description : "Image", limit : 1, file_types : "*.jpg", }) }); </script> <body> <form action="page3.php" method="post" enctype="multipart/form-data" name="frm1" id="frm1"> //Some other text fields <input type="submit" name="submit" id="submit" value="Submit" /> </form> </body> page2.php <?php session_start(); $a = $_SESSION['a']; $b = $_SESSION['b']; $c = $_SESSION['c']; $res = mysql_query("SELECT col FROM table WHERE col1 = $a AND col2 = $b AND col3 = $c LIMIT 1"); $num_rows = mysql_num_rows($res); echo $num_rows; //echos 0 when in fact it should have been 1 because the data in the Session exists. //Ok let's proceed further //... Do some stuff... //Store some more values and create new session variables (and assume that page1.php is going to be able to use it) $_SESSION['d'] = 'd'; $_SESSION['e'] = 'e'; $_SESSION['f'] = 'f'; if (move_uploaded_file($_FILES['file']['tmp_name'], $file)) { echo "success"; } else { echo "error ".$_FILES['file']['error']; } ?> page3.php <?php session_start(); if( isset($_POST['submit']) ) { //These sessions are non-existent although the AJAX request //to page2.php may have created them when called via AJAX from within page1.php echo $_SESSION['d'].$_SESSION['e'].$_SESSION['f']; ?> } ?> As the code says it I am posting some info via AJAX call from page1.php to page2.php. page2.php is supposed to be able to use the session values from page1.php i.e. $_SESSION['a'], $_SESSION['b'] and $_SESSION['c'] but it does not. Why? How can I fix this? page2.php is creating some more sessions after some processing is done and a response is sent back to page1.php. The submit button of the form on page1.php is hit and the page gets POST'ed to page3.php. But when the SESSION info that gets created in page2.php is echoed, it's blank signifying that SESSIONS from page2.php are not used. How can I fix this? I looked over a lot of information and have spent about 50 hours trying to do different things with my scripts before arriving at the above conclusions. My app. is custom made using function (not OOPS) and does not use any PHP frameworks & I am not even about to use any as my knowledge of OOP concepts is limited any many frameworks are object oriented. I came across race conditions, but the solutions provided don't help too much. One more solution of using DB to hold sessions and seek and retrieve from DB is the last thing on my mind and I really want to avoid creating table, coding and maintaining code for a task as simple as just keeping sessions across pages in the same domain. So my request is: Is there a way that I can solve the above problem(s) via simple coding in present conditions? Any help is appreciated. Thank you.

  • How to write a bison grammer for WDI?

    - by Rizo
    I need some help in bison grammar construction. From my another question: I'm trying to make a meta-language for writing markup code (such as xml and html) wich can be directly embedded into C/C++ code. Here is a simple sample written in this language, I call it WDI (Web Development Interface): /* * Simple wdi/html sample source code */ #include <mySite> string name = "myName"; string toCapital(string str); html { head { title { mySiteTitle; } link(rel="stylesheet", href="style.css"); } body(id="default") { // Page content wrapper div(id="wrapper", class="some_class") { h1 { "Hello, " + toCapital(name) + "!"; } // Lists post ul(id="post_list") { for(post in posts) { li { a(href=post.getID()) { post.tilte; } } } } } } } Basically it is a C source with a user-friendly interface for html. As you can see the traditional tag-based style is substituted by C-like, with blocks delimited by curly braces. I need to build an interpreter to translate this code to html and posteriorly insert it into C, so that it can be compiled. The C part stays intact. Inside the wdi source it is not necessary to use prints, every return statement will be used for output (in printf function). The program's output will be clean html code. So, for example a heading 1 tag would be transformed like this: h1 { "Hello, " + toCapital(name) + "!"; } // would become: printf("<h1>Hello, %s!</h1>", toCapital(name)); My main goal is to create an interpreter to translate wdi source to html like this: tag(attributes) {content} = <tag attributes>content</tag> Secondly, html code returned by the interpreter has to be inserted into C code with printfs. Variables and functions that occur inside wdi should also be sorted in order to use them as printf parameters (the case of toCapital(name) in sample source). Here are my flex/bison files: id [a-zA-Z_]([a-zA-Z0-9_])* number [0-9]+ string \".*\" %% {id} { yylval.string = strdup(yytext); return(ID); } {number} { yylval.number = atoi(yytext); return(NUMBER); } {string} { yylval.string = strdup(yytext); return(STRING); } "(" { return(LPAREN); } ")" { return(RPAREN); } "{" { return(LBRACE); } "}" { return(RBRACE); } "=" { return(ASSIGN); } "," { return(COMMA); } ";" { return(SEMICOLON); } \n|\r|\f { /* ignore EOL */ } [ \t]+ { /* ignore whitespace */ } . { /* return(CCODE); Find C source */ } %% %start wdi %token LPAREN RPAREN LBRACE RBRACE ASSIGN COMMA SEMICOLON CCODE QUOTE %union { int number; char *string; } %token <string> ID STRING %token <number> NUMBER %% wdi : /* empty */ | blocks ; blocks : block | blocks block ; block : head SEMICOLON | head body ; head : ID | ID attributes ; attributes : LPAREN RPAREN | LPAREN attribute_list RPAREN ; attribute_list : attribute | attribute COMMA attribute_list ; attribute : key ASSIGN value ; key : ID {$$=$1} ; value : STRING {$$=$1} /*| NUMBER*/ /*| CCODE*/ ; body : LBRACE content RBRACE ; content : /* */ | blocks | STRING SEMICOLON | NUMBER SEMICOLON | CCODE ; %% I am having difficulties on defining a proper grammar for the language, specially in splitting WDI and C code . I just started learning language processing techniques so I need some orientation. Could someone correct my code or give some examples of what is the right way to solve this problem?

  • Why is my mdadm raid-1 recovery so slow?

    - by dimmer
    On a system I'm running Ubuntu 10.04. My raid-1 restore started out fast but quickly became ridiculously slow (at this rate the restore will take 150 days!): dimmer@paimon:~$ cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md0 : active raid1 sdc1[2] sdb1[1] 1953513408 blocks [2/1] [_U] [====>................] recovery = 24.4% (477497344/1953513408) finish=217368.0min speed=113K/sec unused devices: <none> Eventhough I have set the kernel variables to reasonably quick values: dimmer@paimon:~$ cat /proc/sys/dev/raid/speed_limit_min 1000000 dimmer@paimon:~$ cat /proc/sys/dev/raid/speed_limit_max 100000000 I am using 2 2.0TB Western Digital Hard Disks, WDC WD20EARS-00M and WDC WD20EARS-00J.

  • Magento Admin Custom Sales Report

    - by Ela
    Hi, I have to develop a module to export collection of product,order,customer combined attributes. So i thought rather than modifying the core sales report for this purpose better to do a custom functionality. These are the steps that i did but i am not able to produce it. Used magento 1.4.1 version for this. Under /var/www/magento141/app/code/core/Mage/Reports/etc/adminhtml.xml Added these lines for menus. <ereaders translate="title" module="reports"> <title>EReader Sales Report</title> <children> <ereaders translate="title" module="reports"> <title>Sales Report</title> <action>adminhtml/report_sales/ereaders</action> </ereaders> </children> </ereaders> Under /var/www/magento141/app/design/adminhtml/default/default/layout/sales.xml Added these lines for filter condition. <adminhtml_report_sales_ereaders> <update handle="report_sales"/> <reference name="content"> <block type="adminhtml/report_sales_sales" template="report/grid/container.phtml" name="sales.report.grid.container"> <block type="adminhtml/store_switcher" template="report/store/switcher/enhanced.phtml" name="store.switcher"> <action method="setStoreVarName"><var_name>store_ids</var_name></action> </block> <block type="sales/adminhtml_report_filter_form_order" name="grid.filter.form"> ---- </block> </block> </reference> </adminhtml_report_sales_ereaders> And then copied the needed block,model files from sales and renamed all of them into ereaders under /var/www/magento141/app/code/core/Mage/Adminhtml/. Then placed action for ereaders under /var/www/magento141/app/code/core/Mage/Adminhtml/controllers/Report/SalesController.php public function ereadersAction() { $this->_title($this->__('Reports'))->_title($this->__('Sales'))->_title($this->__('EReaders Sales')); $this->_showLastExecutionTime(Mage_Reports_Model_Flag::REPORT_ORDER_FLAG_CODE, 'ereaders'); $this->_initAction() ->_setActiveMenu('report/sales/ereaders') ->_addBreadcrumb(Mage::helper('adminhtml')->__('EReaders Sales Report'), Mage::helper('adminhtml')->__('EReaders Sales Report')); $gridBlock = $this->getLayout()->getBlock('report_sales_ereaders.grid'); $filterFormBlock = $this->getLayout()->getBlock('grid.filter.form'); $this->_initReportAction(array( $gridBlock, $filterFormBlock )); $this->renderLayout(); } Here when i use var_dump == //var_dump($this-getLayout()-getBlock('report_sales_ereaders.grid')); am getting bool(false) only. It does not call the ereaders grid, instead of its still loading blocks and grids from Sales only. I searched most of the files related to report, am not still able to find out the problem. Hope many of you gone through these sort of issues, please can anyone tell me where am making mistake or missing something.

  • opengl 3d texture issue

    - by user1478217
    Hi i'm trying to use a 3d texture in opengl to implement volume rendering. Each voxel has an rgba colour value and is currently rendered as a screen facing quad.(for testing purposes). I just can't seem to get the sampler to give me a colour value in the shader. The quads always end up black. When I change the shader to generate a colour (based on xyz coords) then it works fine. I'm loading the texture with the following code: glGenTextures(1, &tex3D); glBindTexture(GL_TEXTURE_3D, tex3D); unsigned int colours[8]; colours[0] = Colour::AsBytes<unsigned int>(Colour::Blue); colours[1] = Colour::AsBytes<unsigned int>(Colour::Red); colours[2] = Colour::AsBytes<unsigned int>(Colour::Green); colours[3] = Colour::AsBytes<unsigned int>(Colour::Magenta); colours[4] = Colour::AsBytes<unsigned int>(Colour::Cyan); colours[5] = Colour::AsBytes<unsigned int>(Colour::Yellow); colours[6] = Colour::AsBytes<unsigned int>(Colour::White); colours[7] = Colour::AsBytes<unsigned int>(Colour::Black); glTexImage3D(GL_TEXTURE_3D, 0, GL_RGBA, 2, 2, 2, 0, GL_RGBA, GL_UNSIGNED_BYTE, colours); The colours array contains the correct data, i.e. the first four bytes have values 0, 0, 255, 255 for blue. Before rendering I bind the texture to the 2nd texture unit like so: glActiveTexture(GL_TEXTURE1); glBindTexture(GL_TEXTURE_3D, tex3D); And render with the following code: shaders["DVR"]->Use(); shaders["DVR"]->Uniforms["volTex"].SetValue(1); shaders["DVR"]->Uniforms["World"].SetValue(Mat4(vl_one)); shaders["DVR"]->Uniforms["viewProj"].SetValue(cam->GetViewTransform() * cam->GetProjectionMatrix()); QuadDrawer::DrawQuads(8); I have used these classes for setting shader params before and they work fine. The quaddrawer draws eight instanced quads. The vertex shader code looks like this: #version 330 layout(location = 0) in vec2 position; layout(location = 1) in vec2 texCoord; uniform sampler3D volTex; ivec3 size = ivec3(2, 2, 2); uniform mat4 World; uniform mat4 viewProj; smooth out vec4 colour; void main() { vec3 texCoord3D; int num = gl_InstanceID; texCoord3D.x = num % size.x; texCoord3D.y = (num / size.x) % size.y; texCoord3D.z = (num / (size.x * size.y)); texCoord3D /= size; texCoord3D *= 2.0; texCoord3D -= 1.0; colour = texture(volTex, texCoord3D); //colour = vec4(texCoord3D, 1.0); gl_Position = viewProj * World * vec4(texCoord3D, 1.0) + (vec4(position.x, position.y, 0.0, 0.0) * 0.05); } uncommenting the line where I set the colour value equal to the texcoord works fine, and makes the quads coloured. The fragment shader is simply: #version 330 smooth in vec4 colour; out vec4 outColour; void main() { outColour = colour; } So my question is, what am I doing wrong, why is the sampler not getting any colour values from the 3d texture? [EDIT] Figured it out but can't self answer (new user): As soon as I posted this I figured it out, I'll put the answer up to help anyone else (it's not specifically a 3d texture issue, and i've also fallen afoul of it before, D'oh!). I didn't generate mipmaps for the texture, and the default magnification/minification filters weren't set to either GL_LINEAR, or GL_NEAREST. Boom! no textures. Same thing happens with 2d textures.

  • Why is this XMLHttpRequest sample from Mozilla is not working in Firefox 3?

    - by j0rd4n
    I'm trying to get the sample code from Mozilla that consumes a REST web service to work under Firefox 3.0.10. The following code does NOT work in Firefox but does in IE 8! Why is this not working? Does IE 8 have support for XMLHttpRequest? Most examples I've seen use the ActiveX allocation. What should I be doing? XMLHttpRequest seems more standardized. Sample: var req = new XMLHttpRequest(); req.open('GET', 'http://localhost/myRESTfulService/resource', false); // throws 'undefined' exception req.send(null); if(req.status == 0) dump(req.responseText); The open statement is throwing an exception with the description 'undefined'. This is strange as I allocate the req object, am running it in Firefox, and checked to make sure it is defined before calling open (which it says it is of type 'object'). I've also tried the asynchronous version of this with no luck. EDIT 2: Below is my most recent code: function createRequestObject() { if( window.XMLHttpRequest ) { return new XMLHttpRequest(); } else if( window.ActiveXObject ) { return new ActiveXObject( "Microsoft.XMLHTTP" ); } return null; } function handleResponse( req ) { document.writeln( "Handling response..." ); // NEVER GETS CALLED if( req.readyState == 0 ) { document.writeln( "UNITIALIZED" ); } else if( req.readyState == 1 ) { document.writeln( "LOADING" ); } else if( req.readyState == 2 ) { document.writeln( "LOADED" ); } else if( req.readyState == 3 ) { document.writeln( "INTERACTIVE" ); } else if( req.readyState == 4 ) { document.writeln( "COMPLETE" ); if( req.status == 200 ) { document.writeln( "SUCCESS" ); } } } document.writeln( "" ); var req = createRequestObject(); try { document.writeln( "Opening service..." ); req.onreadystatechange = function() { handleResponse( req ); }; req.open('POST', 'http://localhost/test/test2.txt', true); // WORKS IN IE8 & NOT FIREFOX document.writeln( "Sending service request..." ); req.send(''); document.writeln( "Done" ); } catch( err ) { document.writeln( "ERROR: " + err.description ); } EDIT 3: Alright, I reworked this in jQuery. jQuery works great in IE but it throws 'Undefined' when running from Firefox. I double checked and 'Enable JavaScript' is turned on in Firefox - seems to work fine in all other web pages. Below is the jQuery code: function handleResponse( resp ) { alert( "Name: " + resp.Name ); alert( "URL: " + resp.URL ); } $(document).ready( function() { $("a").click( function(event) { try { $.get( "http://localhost/services/ezekielservices/configservice/ezekielservices.svc/test", "{}", function(data) { handleResponse( data ); }, "json" ); } catch( err ) { alert("'$.get' threw an exception: " + err.description); } event.preventDefault(); }); } ); // End 'ready' check Summary of Solution: Alright, web lesson 101. My problem was indeed cross-domain. I was viewing my site unpublished (just on the file system) which was hitting a published service. When I published my site under the same domain it worked. Which also brings up an important distinction between IE and Firefox. When IE experiences this scenario, it prompts the user whether or not they accept the cross-domain call. Firefox throws an exception. While I'm fine with an exception, a more descriptive one would have been helpful. Thanks for all those who helped me.

  • Deleting unreferenced child records with nhibernate

    - by Chev
    Hi There I am working on a mvc app using nhibernate as the orm (ncommon framework) I have parent/child entities: Product, Vendor & ProductVendors and a one to many relationship between them with Product having a ProductVendors collection Product.ProductVendors. I currently am retrieving a Product object and eager loading the children and sending these down the wire to my asp.net mvc client. A user will then modify the list of Vendors and post the updated Product back. I am using a custom model binder to generate the modified Product entity. I am able to update the Product fine and insert new ProductVendors. My problem is that dereferenced ProductVendors are not cascade deleted when specifying Product.ProductVendors.Clear() and calling _productRepository.Save(product). The problem seems to be with attaching the detached instance. Here are my mapping files: Product <?xml version="1.0" encoding="utf-8" ?> <id name="Id"> <generator class="guid.comb" /> </id> <version name="LastModified" unsaved-value="0" column="LastModified" /> <property name="Name" type="String" length="250" /> ProductVendors <?xml version="1.0" encoding="utf-8" ?> <id name="Id"> <generator class="guid.comb" /> </id> <version name="LastModified" unsaved-value="0" column="LastModified" /> <property name="Price" /> <many-to-one name="Product" class="Product" column="ProductId" lazy="false" not-null="true" /> <many-to-one name="Vendor" class="Vendor" column="VendorId" lazy="false" not-null="true" /> Custom Model Binder: using System; using Test.Web.Mvc; using Test.Domain; namespace Spoked.MVC { public class ProductUpdateModelBinder : DefaultModelBinder { private readonly ProductSystem ProductSystem; public ProductUpdateModelBinder(ProductSystem productSystem) { ProductSystem = productSystem; } protected override void OnModelUpdated(ControllerContext controllerContext, ModelBindingContext bindingContext) { var product = bindingContext.Model as Product; if (product != null) { product.Category = ProductSystem.GetCategory(new Guid(bindingContext.ValueProvider["Category"].AttemptedValue)); product.Brand = ProductSystem.GetBrand(new Guid(bindingContext.ValueProvider["Brand"].AttemptedValue)); product.ProductVendors.Clear(); if (bindingContext.ValueProvider["ProductVendors"] != null) { string[] productVendorIds = bindingContext.ValueProvider["ProductVendors"].AttemptedValue.Split(','); foreach (string id in productVendorIds) { product.AddProductVendor(ProductSystem.GetVendor(new Guid(id)), 90m); } } } } } } Controller: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Update(Product product) { using (var scope = new UnitOfWorkScope()) { //product.ProductVendors.Clear(); _productRepository.Save(product); scope.Commit(); } using (new UnitOfWorkScope()) { IList<Vendor> availableVendors = _productSystem.GetAvailableVendors(product); productDetailEditViewModel = new ProductDetailEditViewModel(product, _categoryRepository.Select(x => x).ToList(), _brandRepository.Select(x => x).ToList(), availableVendors); } return RedirectToAction("Edit", "Products", new {id = product.Id.ToString()}); } The following test does pass though: [Test] [NUnit.Framework.Category("ProductTests")] public void Can_Delete_Product_Vendors_By_Dereferencing() { Product product; using(UnitOfWorkScope scope = new UnitOfWorkScope()) { Console.Out.WriteLine("Selecting..."); product = _productRepository.First(); Console.Out.WriteLine("Adding Product Vendor..."); product.AddProductVendor(_vendorRepository.First(), 0m); scope.Commit(); } Console.Out.WriteLine("About to delete Product Vendors..."); using (UnitOfWorkScope scope = new UnitOfWorkScope()) { Console.Out.WriteLine("Clearing Product Vendor..."); _productRepository.Save(product); // seems to be needed to attach entity to the persistance manager product.ProductVendors.Clear(); scope.Commit(); } } Going nuts here as I almost have a very nice solution between mvc, custom model binders and nhibernate. Just not seeing my deletes cascaded. Any help greatly appreciated. Chev

  • Update UI from an event with a thread

    - by tyrone-tudehope
    Im working on a small application to try out an idea that I have. The idea is to periodically update the UI when event of some sort occurs. In the demo I've created, I'm updating a ProgressDialog every 2 seconds for 15 turns. The problem I am having, which I don't quite understand is that when an event is handled, I send a message to the handler which is supposed to update the message in the ProgressDialog. When this happens however, I get an exception which states that I can't update the UI from that thread. The following code appears in my Activity: ProgressDialog diag; String diagMessage = "Started loading..."; final static int MESSAGE_DATA_RECEIVED = 0; final static int MESSAGE_RECEIVE_COMPLETED = 1; final Handler handler = new Handler(){ @Override public void handleMessage(Message msg){ diag.setMessage(diagMessage); switch(msg.what){ case MESSAGE_DATA_RECEIVED: break; case MESSAGE_RECEIVE_COMPLETED: dismissDialog(); killDialog(); break; } } }; Boolean isRunning = false; /** * Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setupDialog(); if(isRunning){ showDialog(); } setContentView(R.layout.main); } void setupDialog(){ if(diag == null){ diag = new ProgressDialog(ThreadLoading.this); diag.setMessage(diagMessage); } } void showDialog(){ isRunning = true; if(diag != null && !diag.isShowing()){ diag.show(); } } void dismissDialog(){ if(diag != null && diag.isShowing()){ diag.dismiss(); } } void killDialog(){ isRunning = false; } public void onStart(){ super.onStart(); showDialog(); Thread background = new Thread(new Runnable(){ public void run(){ try{ final ThreadRunner tr = new ThreadRunner(); tr.setOnDataReceivedListener(new ThreadRunner.OnDataReceivedListener(){ public void onDataReceived(String message){ diagMessage = message; handler.handleMessage(handler.obtainMessage(MESSAGE_DATA_RECEIVED)); } }); tr.setOnDataDownloadCompletedEventListener(new ThreadRunner.OnDataDownloadCompletedListener(){ public void onDataDownloadCompleted(String message){ diagMessage = message; handler.handleMessage(handler.obtainMessage(MESSAGE_RECEIVE_COMPLETED)); } }); tr.runProcess(); } catch(Throwable t){ throw new RuntimeException(t); } } }); background.start(); } @Override public void onPause(){ super.onPause(); dismissDialog(); } For curiosity sake, here's the code for the ThreadRunner class: public interface OnDataReceivedListener { public void onDataReceived(String message); } public interface OnDataDownloadCompletedListener { public void onDataDownloadCompleted(String message); } private OnDataReceivedListener onDataReceivedEventListener; private OnDataDownloadCompletedListener onDataDownloadCompletedEventListener; int maxLoop = 15; int loopCount = 0; int sleepTime = 2000; public void setOnDataReceivedListener(OnDataReceivedListener onDataReceivedListener){ this.onDataReceivedEventListener = onDataReceivedListener; } public void setOnDataDownloadCompletedEventListener(OnDataDownloadCompletedListener onDataDownloadCompletedListener){ this.onDataDownloadCompletedEventListener = onDataDownloadCompletedListener; } public void runProcess(){ for(loopCount = 0; loopCount < maxLoop; loopCount++){ try{ Thread.sleep(sleepTime); onDataReceivedEventListener.onDataReceived(Integer.toString(loopCount)); } catch(Throwable t){ throw new RuntimeException(t); } } onDataDownloadCompletedEventListener.onDataDownloadCompleted("Download is completed"); } Am I missing something? The logic makes sense to me and it looks like everything should work, I'm using a handler to update the UI like it is recommended. Any help will be appreciated. Thanks, Tyrone P.S. I'm developing for Android 1.5

  • segmented controls mangled during initial transition animation

    - by dLux
    greetings and salutations folks, i'm relatively new to objective c & iphone programming, so bare with me if i've overlooked something obvious.. i created a simple app to play with the different transition animations, setting up a couple segmented controls and a slider.. (Flip/Curl), (left/right) | (up/down), (EaseInOut/EaseIn/EaseOut/Linear) i created a view controller class, and the super view controller switches between 2 instances of the sub class. as you can see from the following image, the first time switching to the 2nd instance, while the animation is occurring the segmented controls are mangled; i'd guess they haven't had enuff time to draw themselves completely.. http://img689.imageshack.us/img689/2320/mangledbuttonsduringtra.png they're fine once the animation is done, and any subsequent times.. if i specify cache:NO in the setAnimationTransition it helps, but there still seems to be some sort of progressive reveal for the text in the segmented controls; they still don't seem to be pre-rendered or initialized properly.. (and surely there's a way to do this while caching the view being transitioned to, since in this case the view isn't changing and should be cacheable.) i'm building my code based on a couple tutorials from a book, so i updated the didReceiveMemoryWarning to set the instanced view controllers to nil; when i invoke a memory warning in the simulator, i assume it's purging the other view, and it acts like a first transition after loading, the view being transitioned to appears just like the image above.. i guess it can't hurt to include the code (sorry if it's considered spamming), this is basically half of it, with a similar chunk following this in an else statement, for the case of the 2nd side being present, switching back to the 1st..: - (IBAction)switchViews:(id)sender { [UIView beginAnimations:@"Transition Animation" context:nil]; if (self.sideBViewController.view.superview == nil) // sideA is active, sideB is coming { if (self.sideBViewController == nil) { SideAViewController *sBController = [[SideAViewController alloc] initWithNibName:@"SideAViewController" bundle:nil]; self.sideBViewController = sBController; [sBController release]; } [UIView setAnimationDuration:sideAViewController.transitionDurationSlider.value]; if ([sideAViewController.transitionAnimation selectedSegmentIndex] == 0) { // flip: 0 == left, 1 == right if ([sideAViewController.flipDirection selectedSegmentIndex] == 0) [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.view cache:YES]; else [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view cache:YES]; } else { // curl: 0 == up, 1 == down if ([sideAViewController.curlDirection selectedSegmentIndex] == 0) [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view cache:YES]; else [UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view cache:YES]; } if ([sideAViewController.animationCurve selectedSegmentIndex] == 0) [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; else if ([sideAViewController.animationCurve selectedSegmentIndex] == 1) [UIView setAnimationCurve:UIViewAnimationCurveEaseIn]; else if ([sideAViewController.animationCurve selectedSegmentIndex] == 2) [UIView setAnimationCurve:UIViewAnimationCurveEaseOut]; else if ([sideAViewController.animationCurve selectedSegmentIndex] == 3) [UIView setAnimationCurve:UIViewAnimationCurveLinear]; [sideBViewController viewWillAppear:YES]; [sideAViewController viewWillDisappear:YES]; [sideAViewController.view removeFromSuperview]; [self.view insertSubview:sideBViewController.view atIndex:0]; [sideBViewController viewDidAppear:YES]; [sideAViewController viewDidDisappear:YES]; } any other tips or pointers about writing good clean code is also appreciated, i realize i still have a lot to learn.. thank u for ur time, -- d

  • globals and locals in python exec()

    - by hawkettc
    Hi, I'm trying to run a piece of python code using exec. my_code = """ class A(object): pass print 'locals: %s' % locals() print 'A: %s' % A class B(object): a_ref = A """ global_env = {} local_env = {} my_code_AST = compile(my_code, "My Code", "exec") exec(my_code_AST, global_env, local_env) print local_env which results in the following output locals: {'A': <class 'A'>} A: <class 'A'> Traceback (most recent call last): File "python_test.py", line 16, in <module> exec(my_code_AST, global_env, local_env) File "My Code", line 8, in <module> File "My Code", line 9, in B NameError: name 'A' is not defined However, if I change the code to this - my_code = """ class A(object): pass print 'locals: %s' % locals() print 'A: %s' % A class B(A): pass """ global_env = {} local_env = {} my_code_AST = compile(my_code, "My Code", "exec") exec(my_code_AST, global_env, local_env) print local_env then it works fine - giving the following output - locals: {'A': <class 'A'>} A: <class 'A'> {'A': <class 'A'>, 'B': <class 'B'>} Clearly A is present and accessible - what's going wrong in the first piece of code? I'm using 2.6.5, cheers, Colin * UPDATE 1 * If I check the locals() inside the class - my_code = """ class A(object): pass print 'locals: %s' % locals() print 'A: %s' % A class B(object): print locals() a_ref = A """ global_env = {} local_env = {} my_code_AST = compile(my_code, "My Code", "exec") exec(my_code_AST, global_env, local_env) print local_env Then it becomes clear that locals() is not the same in both places - locals: {'A': <class 'A'>} A: <class 'A'> {'__module__': '__builtin__'} Traceback (most recent call last): File "python_test.py", line 16, in <module> exec(my_code_AST, global_env, local_env) File "My Code", line 8, in <module> File "My Code", line 10, in B NameError: name 'A' is not defined However, if I do this, there is no problem - def f(): class A(object): pass class B(object): a_ref = A f() print 'Finished OK' * UPDATE 2 * ok, so the docs here - http://docs.python.org/reference/executionmodel.html 'A class definition is an executable statement that may use and define names. These references follow the normal rules for name resolution. The namespace of the class definition becomes the attribute dictionary of the class. Names defined at the class scope are not visible in methods.' It seems to me that 'A' should be made available as a free variable within the executable statement that is the definition of B, and this happens when we call f(), but not when we use exec(). This can be more easily shown with the following - my_code = """ class A(object): pass print 'locals in body: %s' % locals() print 'A: %s' % A def f(): print 'A in f: %s' % A f() class B(object): a_ref = A """ which outputs locals in body: {'A': <class 'A'>} A: <class 'A'> Traceback (most recent call last): File "python_test.py", line 20, in <module> exec(my_code_AST, global_env, local_env) File "My Code", line 11, in <module> File "My Code", line 9, in f NameError: global name 'A' is not defined So I guess the new question is - why aren't those locals being exposed as free variables in functions and class definitions - it seems like a pretty standard closure scenario.

  • Delay in displaying contents in JDialog

    Please have a look at the following code import java.awt.*; import java.awt.event.*; import javax.swing.*; import java.util.List; import java.util.ArrayList; public class SendEmailForm extends JDialog { private JLabel to, cc, bcc, subject, account; private JTextField toTxt, ccTxt, bccTxt, subjectTxt; private JTextArea messageTxt; private JButton send; private JComboBox accountBox; private JScrollPane scroll; private GridBagLayout gbl; private GridBagConstraints gbc; public SendEmailForm() { //Declaring instance variables to = new JLabel("To: "); cc = new JLabel("CC: "); bcc = new JLabel("BCC: "); subject = new JLabel("Subject: "); account = new JLabel("Select an Account: "); toTxt = new JTextField(20); ccTxt = new JTextField(20); bccTxt = new JTextField(20); subjectTxt = new JTextField(20); messageTxt = new JTextArea(20, 50); messageTxt.setLineWrap(true); scroll = new JScrollPane(messageTxt); scroll.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED); scroll.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_NEVER); accountBox = new JComboBox(); accountBox.addItem("Yahoo"); accountBox.addItem("GMail"); accountBox.addItem("MSN"); //accountBox.addItem("Yahoo"); //accountBox.addItem("Yahoo"); JPanel buttonPanel = new JPanel(); buttonPanel.setLayout(new FlowLayout()); send = new JButton("Send"); send.addActionListener(new SendButtonAction()); buttonPanel.add(send); //Creating thr GUI //GUI CREATION IS REMOVED IN THIS POST this.setTitle("Send Emails"); this.setVisible(true); this.pack(); this.setLocationRelativeTo(null); this.validate(); } private class SendButtonAction implements ActionListener { public void actionPerformed(ActionEvent ae) { ProgressMonitor pm = new ProgressMonitor(); //Retreiving the user name and password List userData = new ArrayList(); EmailDBConnector emailCon = new EmailDBHandler(); userData = emailCon.getUserNameAndPassword( accountBox.getSelectedItem().toString().trim()); String userName = userData.get(0).toString(); String password = userData.get(1).toString(); System.out.println(userName); System.out.println(password); pm.setVisible(true); SendEmail sendEmail = new SendEmail(toTxt.getText(), userName.trim(), bccTxt.getText(), ccTxt.getText(), accountBox.getSelectedItem().toString().trim(), messageTxt.getText().trim(), password.trim(), subjectTxt.getText()); String result = sendEmail.send(); //pm.dispose(); JOptionPane.showMessageDialog(null, result); } } private class ProgressMonitor extends JDialog { public ProgressMonitor() { this.setLayout(new BorderLayout()); JLabel text = new JLabel("Sending..Please wait..."); this.add(text, "Center"); this.pack(); this.validate(); this.setLocationRelativeTo(null); } } } First, this is an email program. In here, when the JDialog is called, it just opens as a 100% blank window. I have added a JLabel, but it is not there when it is displaying. Anyway, it takes sometime to send the email, after the email is sent, I can see the JLabel in the JDialog. If I take my issue into one sentence, I am calling the JDialog before the email is sent, but it appears blank, after the email is sent, it's content are there! Why is this? Please help!

  • numpy calling sse2 via ctypes

    - by Daniel
    Hello, In brief, I am trying to call into a shared library from python, more specifically, from numpy. The shared library is implemented in C using sse2 instructions. Enabling optimisation, i.e. building the library with -O2 or –O1, I am facing strange segfaults when calling into the shared library via ctypes. Disabling optimisation (-O0), everything works out as expected, as is the case when linking the library to a c-program directly (optimised or not). Attached you find a snipped which exhibits the delineated behaviour on my system. With optimisation enabled, gdb reports a segfault in __builtin_ia32_loadupd (__P) at emmintrin.h:113. The value of __P is reported as optimised out. test.c: #include <emmintrin.h> #include <complex.h> void test(const int m, const double* x, double complex* y) { int i; __m128d _f, _x, _b; double complex f __attribute__( (aligned(16)) ); double complex b __attribute__( (aligned(16)) ); __m128d* _p; b = 1; _b = _mm_loadu_pd( (double *) &b ); _p = (__m128d*) y; for(i=0; i<m; ++i) { f = cexp(-I*x[i]); _f = _mm_loadu_pd( (double *) &f ); _x = _mm_loadu_pd( (double *) &x[i] ); _f = _mm_shuffle_pd(_f, _f, 1); *_p = _mm_add_pd(*_p, _f); *_p = _mm_add_pd(*_p, _x); *_p = _mm_mul_pd(*_p,_b); _p++; } return; } Compiler flags: gcc -o libtest.so -shared -std=c99 -msse2 -fPIC -O2 -g -lm test.c test.py: import numpy as np import os def zerovec_aligned(nr, dtype=np.float64, boundary=16): '''Create an aligned array of zeros.

Note also that i use _mm_loadu_pd instead of _mm_load_pd when loading b and f. For the C-only version _mm_load_pd works (as expected). However, when calling the function via ctypes using _mm_load_pd always segfaults (independent of optimisation).

  • [BEGINNER] Javascript Pop Ups

    - by user566312
    Hey All, My boss has asked for a page that will not change to have two timed pop ups load. I have found code and edited it to what I had thought it should do, but it is only loading the last onLoad event. I am a designer and I have helped with making webpages, but Javascript is so far outside of what I can understand. I have already learned how to use the single pop up and spent a whiiile learning the timeouts, but I cannot seem to get it to work with multiple popup functions. If you have a moment, would you take a look? Thank you :) h <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>H's Page 1</title> <SCRIPT LANGUAGE="JavaScript"> <!-- Original: Ronnie T.

  • Recursing data into a 2 dimensional array in PHP 5

    - by user315699
    I'm getting bamboozled by "for each" loops and two dimensional arrays, and I'm a php newb so please bear with me (and ignore any variables with the word "image" - it's all about the mp3s, I just didn't change it from the xml tutorial) I found a php function on the net that list files in a directory, the output of which is: Array ( [0] = audio/1.mp3 [1] = audio/2.mp3 [2] = audio/3.mp3 [3] = audio/4.mp3 [4] = audio/5.mp3 ) As expected. And another that lists some info about mp3 files. $mp3datafile = 'audio/1.mp3'; $m = new mp3file($mp3datafile); $mp3dataArray = $m-get_metadata(); print_r($mp3dataArray); unset($mp3dataArray); The output of which is Array ( [Filesize] = 31972 [Encoding] = CBR [etc] ) In order to automatically build RSS for a podcast, I need to generate XML for each item. So far so good. This is how I'm making the xml foreach ($imagearray as $key = $val) { $tnsoundfile = $xml_generator-addChild('item'); $tnsoundfile-addChild('title', $podcasttitle); $enclosure = $tnsoundfile-addChild('enclosure'); $enclosure-addAttribute('url', $val); // that's the filename $enclosure-addAttribute('length', $mp3dataArray[Filesize]); // << Length is file length, not time. But later I also need $mp3dataArray[Length mm:ss] for duration tag. $enclosure-addAttribute('type', 'audio/mpeg'); $tnsoundfile-addChild('guid', $path_to_image_dir.'/'.$val); } (The above has been truncated, I realise it's not proper xml right now, but it was just to show what was going on). Perfect. But I need to do it for as many files as there are in the directory. So, I have an array of the names of the files in the directory in $mp3data And, I have an array of mp3 data in $mp3dataArray from one iteration of the get_metadata() function. If I do the following, then I get a nice list of the mp3 data of the 5 files in the directory: foreach ($mp3data as $key = $val) { $mp3datafile = $val; $m = new mp3file($mp3datafile); $mp3dataArray = $m-get_metadata(); print_r($mp3dataArray); unset($mp3dataArray); } As expected. Where I'm struggling, and have been for most of the day in spite of reading many forums and tutorials, is how to populate the "second dimension" of the array, so that it goes through 1,2,3,4 and 5.mp3 (or however many there are), extracts the metadata, then allows me to use it in the xml section above. Here's what I have foreach ($mp3data as $key = $val) { $mp3datafile = $val; $m = new mp3file($mp3datafile); $mp3dataArray = $m-get_metadata(); $mp3testarray = array($mp3dataArray); } print_r($mp3dataArray); Shouldn't that line print_r($mp3dataArray); give me a nice list of 5 lots of mp3 data, in the way it did when I recursed through the loop as before? Cos this is driving me nuts! It must be something so simple, and any help would be greatly appreciated. Thank you in advance.

  • Jaxb unmarshalls fixml object but all fields are null

    - by DUFF
    I have a small XML document in the FIXML format. I'm unmarshalling them using jaxb. The problem The process complete without errors but the objects which are created are completely null. Every field is empty. The fields which are lists (like the Qty) have the right number of object in them. But the fields of those objects are also null. Setup I've downloaded the FIXML schema from here and I've created the classes with xjc and the maven plugin. They are all in the package org.fixprotocol.fixml_5_0_sp2. I've got the sample xml in a file FIXML.XML <?xml version="1.0" encoding="ISO-8859-1"?> <FIXML> <Batch> <PosRpt> <Pty ID="GS" R="22"/> <Pty ID="01" R="5"/> <Pty ID="6U8" R="28"> <Sub ID="2" Typ="21"/> </Pty> <Pty ID="GS" R="22"/> <Pty ID="6U2" R="2"/> <Instrmt ID="GHPKRW" SecTyp="FWD" MMY="20121018" MatDt="2012-10-18" Mult="1" Exch="GS" PxQteCcy="KJS" FnlSettlCcy="GBP" Fctr="0.192233298" SettlMeth="G" ValMeth="FWDC2" UOM="Ccy" UOMCCy="USD"> <Evnt EventTyp="121" Dt="2013-10-17"/> <Evnt EventTyp="13" Dt="2013-10-17"/> </Instrmt> <Qty Long="0.000" Short="22000000.000" Typ="PNTN"/> <Qty Long="0.000" Short="22000000.000" Typ="FIN"/> <Qty Typ="DLV" Long="0.00" Short="0.00" Net="0.0"/> <Amt Typ="FMTM" Amt="32.332" Ccy="USD"/> <Amt Typ="CASH" Amt="1" Rsn="3" Ccy="USD"/> <Amt Typ="IMTM" Amt="329.19" Ccy="USD"/> <Amt Typ="DLV" Amt="0.00" Ccy="USD"/> <Amt Typ="BANK" Amt="432.23" Ccy="USD"/> </PosRpt> Then I'm calling the unmarshaller with custom event handler which just throws an exception on a parse error. The parsing complete so I know there are no errors being generated. I'm also handling the namespace as suggested here // sort out the file String xmlFile = "C:\\FIXML.XML.xml"; System.out.println("Loading XML File..." + xmlFile); InputStream input = new FileInputStream(xmlFile); InputSource is = new InputSource(input); // create jaxb context JAXBContext jc = JAXBContext.newInstance("org.fixprotocol.fixml_5_0_sp2"); Unmarshaller unmarshaller = jc.createUnmarshaller(); // add event handler so jacB will fail on an error CustomEventHandler validationEventHandler = new CustomEventHandler(); unmarshaller.setEventHandler(validationEventHandler); // set the namespace NamespaceFilter inFilter = new NamespaceFilter("http://www.fixprotocol.org/FIXML-5-0-SP2", true); inFilter.setParent(SAXParserFactory.newInstance().newSAXParser().getXMLReader()); SAXSource source = new SAXSource(inFilter, is); // GO! JAXBElement<FIXML> fixml = unmarshaller.unmarshal(source, FIXML.class); The fixml object is created. In the above sample the Amt array will have five element which matches the number of amts in the file. But all the fields like ccy are null. I've put breakpoints in the classes created by xjc and none of the setters are ever called. So it appears that jaxb is unmarshalling and creating all the correct objects, but it's never calling the setters?? I'm completely stumped on this. I've seen a few posts that suggrest making sure the package.info file that was generated by xjc is in the packags and I've made sure that it's there. There are no working in the IDE about the generated code. Any help much appreciated.

  • MySQL query - if not exists - insert into - else - update

    I made a simple document generator by the form, this form saves everything to mysql database, It works great, but when someone type a the same 'nrumowy' it creates a new row in mysql, 'nrumowy' is unique, so when someone adds a form with the same 'nrumowy' I want to just update existing data in mysql, I have that code: $con=mysqli_connect("localhost","login","pass","database"); // Check connection if (mysqli_connect_errno()) { echo "Failed to connect to MySQL: " . mysqli_connect_error(); } // escape variables for security $numerklienta = mysqli_real_escape_string($con, $_POST['numerklienta']); $name = mysqli_real_escape_string($con, $_POST['name']); $hours = mysqli_real_escape_string($con, $_POST['hours']); $date = mysqli_real_escape_string($con, $_POST['date']); $beginDate = mysqli_real_escape_string($con, $_POST['beginDate']); $nrdomu = mysqli_real_escape_string($con, $_POST['nrdomu']); $telefon = mysqli_real_escape_string($con, $_POST['telefon']); $fax = mysqli_real_escape_string($con, $_POST['fax']); $nip = mysqli_real_escape_string($con, $_POST['nip']); $email = mysqli_real_escape_string($con, $_POST['email']); $stronawww = mysqli_real_escape_string($con, $_POST['stronawww']); $branza = mysqli_real_escape_string($con, $_POST['branza']); $vatkodpocztowy = mysqli_real_escape_string($con, $_POST['vatkodpocztowy']); $vatmiejscowosc = mysqli_real_escape_string($con, $_POST['vatmiejscowosc']); $vatulica = mysqli_real_escape_string($con, $_POST['vatulica']); $vatnrdomu = mysqli_real_escape_string($con, $_POST['vatnrdomu']); $vatemail = mysqli_real_escape_string($con, $_POST['vatemail']); $vatosoba = mysqli_real_escape_string($con, $_POST['vatosoba']); $datapublikacji = mysqli_real_escape_string($con, $_POST['datapublikacji']); $rabat = mysqli_real_escape_string($con, $_POST['rabat']); $wartoscnetto = mysqli_real_escape_string($con, $_POST['wartoscnetto']); $typreklamy = mysqli_real_escape_string($con, $_POST['typreklamy']); $inne = mysqli_real_escape_string($con, $_POST['inne']); $inne2 = mysqli_real_escape_string($con, $_POST['inne2']); $inne3 = mysqli_real_escape_string($con, $_POST['inne3']); $zaliczka = mysqli_real_escape_string($con, $_POST['zaliczka']); $liczbarat1 = mysqli_real_escape_string($con, $_POST['liczbarat1']); $zaakceptowaneprzez = mysqli_real_escape_string($con, $_POST['zaakceptowaneprzez']); $telzam = mysqli_real_escape_string($con, $_POST['telzam']); $datapodpis = mysqli_real_escape_string($con, $_POST['datapodpis']); $nrumowy = mysqli_real_escape_string($con, $_POST['nrumowy']); $sql="IF NOT EXISTS ( SELECT * FROM zam WHERE nrumowy = '$nrumowy' ) THEN INSERT INTO zam (numerklienta, name, hours, date, beginDate, nrdomu, telefon, fax, nip, email, stronawww, branza, vatkodpocztowy, vatmiejscowosc, vatulica, vatnrdomu, vatemail, vatosoba, datapublikacji, rabat, wartoscnetto, typreklamy, inne, inne2, inne3, zaliczka, liczbarat1, zaakceptowaneprzez, telzam, datapodpis, nrumowy) VALUES ('$numerklienta', '$name', '$hours', '$date', '$beginDate', '$nrdomu', '$telefon', '$fax', '$nip', '$email', '$stronawww', '$branza', '$vatkodpocztowy', '$vatmiejscowosc', '$vatulica', '$vatnrdomu', '$vatemail', '$vatosoba', '$datapublikacji', '$rabat', '$wartoscnetto', '$typreklamy', '$inne', '$inne2', '$inne3', '$zaliczka', '$liczbarat1', '$zaakceptowaneprzez', '$telzam', '$datapodpis', '$nrumowy' ) ELSE UPDATE zam SET name = '$name', numerklienta = '$numerklienta', hours = '$hours', date = '$date', beginDate = '$beginDate', nrdomu = '$nrdomu', telefon = '$telefon', fax = '$fax', nip = '$nip', email = '$email', stronawww = '$stronawww', branza = '$branza', vatkodpocztowy = '$vatkodpocztowy', vatmiejscowosc = '$vatmiejscowosc', vatulica = '$vatulica', vatnrdomu = '$vatnrdomu', vatemail = '$vatemail', vatosoba = '$vatosoba', datapublikacji = '$datapublikacji', rabat = '$rabat', wartoscnetto = '$wartoscnetto', typreklamy = '$typreklamy', inne = '$inne', inne2 = '$inne2', inne3 = '$inne3', zaliczka = '$zaliczka', liczbarat1 = '$liczbarat1', zaakceptowaneprzez = '$zaakceptowaneprzez', telzam = '$telzam', datapodpis = '$datapodpis' WHERE nrumowy ='$nrumowy' END IF"; if (!mysqli_query($con,$sql)) { die('Error: ' . mysqli_error($con)); } mysqli_close($con); This query without " select.....

  • jQuery - I'm getting unexpected outputs from a basic math formula.

    - by OllieMcCarthy
    Hi I would like to start by saying I'd greatly appreciate anyones help on this. I have built a small caculator to calculate the amount a consumer can save annually on energy by installing a ground heat pump or solar panels. As far as I can tell the mathematical formulas are correct and my client verified this yesterday when I showed him the code. Two problems. The first is that the calculator is outputting ridiculously large numbers for the first result. The second problem is that the solar result is only working when there are no zeros in the fields. Are there some quirks as to how one would write mathematical formulas in JS or jQuery? Any help greatly appreciated.

  • Form values appear blank when submitting to the database - Drupal FormAPI

    - by GaxZE
    Hello, I have been working on this drupal form API script for past week and half. to give an insight into my problem.. the form below merely lists a host of database records which contain 5 individual scoring ranks. (mind, action, relationship, language and IT). this code is apart of my own custom module where all values are listed from the database. the idea behind this module is to be able to edit these values on a large scale. I am having trouble getting the values entered in the form to be passed to the variables inside of the marli_admin_submit function. the second problem is the assigning those values to their specific ID. for this purpose id like to add im merely trying to get just one score updated rather than all of them. below is my code. any advice appreciated. function marli_scores(){ $result = pager_query(db_rewrite_sql('SELECT * FROM marli WHERE value != " "')); while ($node = db_fetch_object($result)) { $attribute = $node->attribute; $field = $node->field_name; $item = $node->value; $mind = $node->mind; $action = $node->action; $relationship = $node->relationship; $language = $node->language; $it = $node->it; $form['field'][$node->marli_id] = array('#type' => 'markup', '#value' => $field, '#prefix' => '<b>', '#suffix' => '</b>'); $form['title'][$node->marli_id] = array('#type' => 'markup', '#value' => $item, '#prefix' => '<b>', '#suffix' => '</b>'); $form['mind'][$node->marli_id] = array('#type' => 'textfield', '#maxlength' => '1', '#size' => '1', '#value' => $mind); $form['action'][$node->marli_id] = array('#type' => 'textfield', '#maxlength' => '1', '#size' => '1', '#value' => $action); $form['relationship'][$node->marli_id] = array('#type' => 'textfield', '#maxlength' => '1', '#size' => '1', '#value' => $relationship); $form['language'][$node->marli_id] = array('#type' => 'textfield', '#maxlength' => '1', '#size' => '1', '#value' => $language); $form['it'][$node->marli_id] = array('#type' => 'textfield', '#maxlength' => '1', '#size' => '1', '#value' => $it); } $form['pager'] = array('#value' => theme('pager', NULL, 50, 0)); $form['save'] = array('#type' => 'submit', '#value' => t('Save')); $form['#theme'] = 'marli_scores'; return $form; } function marli_admin_submit($form, &$form_state) { $marli_id = 4; $submit_mind = $form_state['values']['mind'][$marli_id]; $submit_action = $form_state['values']['action'][$marli_id]; $submit_relationship = $form_state['values']['relationship'][$marli_id]; $submit_language = $form_state['values']['language'][$marli_id]; $submit_it = $form_state['values']['it'][$marli_id]; $sql_query = "UPDATE {marli} SET mind = %d, action = %d, relationship = %d, language = %d, it = %d WHERE marli_id = %d"; if ($success = db_query($sql_query, $submit_mind, $submit_action, $submit_relationship, $submit_language, $submit_it)) { drupal_set_message(t(' Values have been saved.')); } else { drupal_set_message(t('There was an error saving your data.

    - by Brrr Ice Tea
    import flash.display.Sprite; import flash.net.URLLoader; var index:int = 0; var constY = 291; var constW = 2; var constH = 40; hydrogenBtn.label = "Hydrogen"; heliumBtn.label = "Helium"; lithiumBtn.label = "Lithium"; hydrogenBtn.addEventListener (MouseEvent.CLICK, loadHydrogen); heliumBtn.addEventListener (MouseEvent.CLICK, loadHelium); lithiumBtn.addEventListener (MouseEvent.CLICK, loadLithium); var myTextLoader:URLLoader = new URLLoader(); myTextLoader.addEventListener(Event.COMPLETE, onLoaded); function loadHydrogen (event:Event):void { myTextLoader.load(new URLRequest("hydrogen.txt")); } function loadHelium (event:Event):void { myTextLoader.load(new URLRequest("helium.txt")); } function loadLithium (event:Event):void { myTextLoader.load(new URLRequest("lithium.txt")); } var DataSet:Array = new Array(); var valueRead1:String; var valueRead2:String; function onLoaded(event:Event):void { var rawData:String = event.target.data; for(var i:int = 0; i<rawData.length; i++){ var commaIndex = rawData.search(","); valueRead1 = rawData.substr(0,commaIndex); rawData = rawData.substr(commaIndex+1, rawData.length+1); DataSet.push(valueRead1); commaIndex = rawData.search(","); if(commaIndex == -1) {commaIndex = rawData.length+1;} valueRead2 = rawData.substr(0,commaIndex); rawData = rawData.substr(commaIndex+1, rawData.length+1); DataSet.push(valueRead2); } generateMask_Emission(DataSet); } function generateMask_Emission(dataArray:Array):void{ var spriteName:String = "Mask"+index; trace(spriteName); this[spriteName] = new Sprite(); for (var i:int=0; i<dataArray.length; i+=2){ this[spriteName].graphics.beginFill(0x000000, dataArray[i+1]); this[spriteName].graphics.drawRect(dataArray[i],constY,constW, constH); this[spriteName].graphics.endFill(); } addChild(this[spriteName]); index++; } Hi, I am relatively new to flash and action script as well and I am having a problem getting the sprite to be removed after another is called. I am making emission spectrum's of 3 elements by dynamically generating the mask over a picture on the stage. Everything works perfectly fine with the code I have right now except the sprites stack on top of each other and I end up with bold lines all over my picture instead of a new set of lines each time i press a button. I have tried using try/catch to remove the sprites and I have also rearranged the entire code from what is seen here to make 3 seperate entities (hoping I could remove them if they were seperate variables) instead of 2 functions that handle the whole process. I have tried everything to the extent of my knowledge (which is pretty minimal @ this point) any suggestions? Thanks ahead of time!

  • How to convert an ORM to its subclass using Hibernate ?

    - by Gaaston
    Hi everybody, For example, I have two classes : Person and Employee (Employee is a subclass of Person). Person : has a lastname and a firstname. Employee : has also a salary. On the client-side, I have a single HTML form where i can fill the person informations (like lastname and firstname). I also have a "switch" between "Person" and "Employee", and if the switch is on Employee I can fill the salary field. On the server-side, Servlets receive informations from the client and use the Hibernate framework to create/update data to/from the database. The mapping i'm using is a single table for persons and employee, with a discriminator. I don't know how to convert a Person in an Employee. I firstly tried to : load the Person p from the database create an empty Employee e object copy values from p into e set the salary value save e into the database But i couldn't, as I also copy the ID, and so Hibernate told me they where two instanciated ORM with the same id. And I can't cast a Person into an Employee directly, as Person is Employee's superclass. There seems to be a dirty way : delete the person, and create an employee with the same informations, but I don't really like it.. So I'd appreciate any help on that :) Some precisions : The person class : public class Person { protected int id; protected String firstName; protected String lastName; // usual getters and setters } The employee class : public class Employee extends Person { // string for now protected String salary; // usual getters and setters } And in the servlet : // type is the "switch" if(request.getParameter("type").equals("Employee")) { Employee employee = daoPerson.getEmployee(Integer.valueOf(request.getParameter("ID"))); modifyPerson(employee, request); employee.setSalary(request.getParameter("salary")); daoPerson.save(employee ); } else { Person person = daoPerson.getPerson(Integer.valueOf(request.getParameter("ID"))); modifyPerson(employee, request); daoPerson.save(person); } And finally, the loading (in the dao) : public Contact getPerson(int ID){ Session session = HibernateSessionFactory.getSession(); Person p = (Person) session.load(Person.class, new Integer(ID)); return p; } public Contact getEmployee(int ID){ Session session = HibernateSessionFactory.getSession(); Employee = (Employee) session.load(Employee.class, new Integer(ID)); return p; } With this, i'm getting a ClassCastException when trying to load a Person using getEmployee. XML Hibernate mapping : <class name="domain.Person" table="PERSON" discriminator-value="P"> <id name="id" type="int"> <column name="ID" /> <generator class="native" /> </id> <discriminator column="type" type="character"/> <property name="firstName" type="java.lang.String"> <column name="FIRSTNAME" /> </property> <property name="lastName" type="java.lang.String"> <column name="LASTNAME" /> </property> <subclass name="domain.Employee" discriminator-value="E"> <property name="salary" column="SALARY" type="java.lang.String" /> </subclass> </class> Is it clear enough ? :-/

  • Cant bind data to a table view

    - by sudhakarilla
    Hi, I have retrieved data from Json URL and displayed it in a table view. I have also inlcuced a button in table view. On clicking the button the data must be transferred to a another table view. The problem is that i could send the data to a view and could display it on a label. But i couldnt bind the dat to table view ... Here's some of the code snippets... Buy Button... -(IBAction)Buybutton{ /* UIAlertView *alert =[[UIAlertView alloc]initWithTitle:@"thank u" message:@"products" delegate:nil cancelButtonTitle:@"ok" otherButtonTitles:nil]; [alert show]; [alert release];*/ Product *selectedProduct = [[data products]objectAtIndex:0]; CartViewController *cartviewcontroller = [[[CartViewController alloc] initWithNibName:@"CartViewController" bundle:nil]autorelease]; cartviewcontroller.product= selectedProduct; //NSString *productname=[product ProductName]; //[currentproducts setproduct:productname]; [self.view addSubview:cartviewcontroller.view]; } CartView... // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; data = [GlobalData SharedData]; NSMutableArray *prod =[[NSMutableArray alloc]init]; prod = [data products]; for(NSDictionary *product in prod) { Cart *myprod = [[Cart alloc]init]; myprod.Description = [product Description]; myprod.ProductImage =[product ProductImage]; myprod.ProductName = [product ProductName]; myprod.SalePrice = [product SalePrice]; [data.carts addObject:myprod]; [myprod release]; } Cart *cart = [[data carts]objectAtIndex:0]; NSString *productname=[cart ProductName]; self.label.text =productname; NSLog(@"carts"); } (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [data.carts count]; } -(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { return 75; } (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSLog(@"cellforrow"); static NSString *CellIdentifier = @"Cell"; ProductCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if(cell ==nil) { cell = [[[ProductCell alloc]initWithFrame:CGRectZero reuseIdentifier:CellIdentifier]autorelease]; } NSUInteger row = [indexPath row]; Cart *cart = [[data carts]objectAtIndex:row]; cell.productNameLabel.text = [cart ProductName]; /*NSString *sale = [[NSString alloc]initWithFormat:@"SalePrice:%@",[cart SalePrice]]; cell.salePriceLabel.text = sale; cell.DescriptionLabel.text = [cart Description]; NSMutableString imageUrl =[NSMutableString string]; [imageUrl appendFormat:@"http://demo.s2commerce.net/DesktopModules/S2Commerce/Images/Products/%@",[product ProductImage]]; NSLog(@"imageurl:%@",imageUrl); NSString mapURL = [imageUrl stringByReplacingPercentEscapesUsingEncoding:NSASCIIStringEncoding]; NSData* imageData = [[NSData alloc]initWithContentsOfURL:[NSURL URLWithString:mapURL]]; UIImage* image = [[UIImage alloc]initWithData:imageData]; cell.productImageview.image = image; [imageData release]; [image release];*/ return cell; } I am also getting the following error in the console 2010-06-11 18:34:29.169 navigation[4109:207] * -[CartViewController tableView:numberOfRowsInSection:]: message sent to deallocated instance 0xcb4d4f90
