• Why does Cut/Paste of form components sometimes stop working in Delphi 2007 IDE?

  - by robsoft

  This is driving me crazy. I'm not going to take it anymore. I'm going to ask, even at the risk of eternal public humiliation! (If it's something really obvious or that I've done to the system myself). For reasons I've never quite had the patience to work out, every so often the form I'm working on in Delphi 2007's visual form editor goes 'pseudo-read-only'; I can add new components to the form, I can move/resize existing ones (and change any properties in the Object Inspector), and I can select a component and 'copy' it to the clipboard. But I'm completely unable to cut a component from the form, or paste a new copy down. I don't believe it's to do with the 'Lock Controls' Edit menu option as I can toggle this on or off and it has the effect it's supposed to - this disappearance of Cut & Paste happens on the right-click context menu, from the keyboard and from the main Edit menu - it's as if the form has become read only to thing to do with the clipboard. If I close the form in the IDE and then reopen it, everything starts working fine again (just as D1, D3, D5 and D7 always did for me, previously). I'm not going mad, as I'm sure I read something about why this happens on a newsgroup once and it's caught me out from time to time many many times in the last few months, but I've failed to find the newsgroup reference this evening and I've decided that, as more and more Delphi users seem to be making use of StackOverflow, it was worth asking here. Help - when I'm doing lots of form-work it drives me absolutely mad!

• jqGrid - edit function never getting called

  - by dcp

  I'm having a problem with JQGrid using ASP.NET MVC. I'm trying to follow this example (after you go to that link, over on the left side of the page please click Live Data Manipulation, then Edit Row), but my edit function is never getting called (i.e. it's never getting into the $("#bedata").click(function(). Does anyone know what could be the problem? <script type="text/javascript"> var lastsel2; jQuery(document).ready(function() { jQuery("#editgrid").jqGrid({ url: '/Home/GetMovieData/', datatype: 'json', mtype: 'GET', colNames: ['id', 'Movie Name', 'Directed By', 'Release Date', 'IMDB Rating', 'Plot', 'ImageURL'], colModel: [ { name: 'id', index: 'Id', width: 55, sortable: false, hidden: true, editable: false, editoptions: { readonly: true, size: 10} }, { name: 'Movie Name', index: 'Name', width: 250, editable: true, editoptions: { size: 10} }, { name: 'Directed By', index: 'Director', width: 250, align: 'right', editable: true, editoptions: { size: 10} }, { name: 'Release Date', index: 'ReleaseDate', width: 100, align: 'right', editable: true, editoptions: { size: 10} }, { name: 'IMDB Rating', index: 'IMDBUserRating', width: 100, align: 'right', editable: true, editoptions: { size: 10} }, { name: 'Plot', index: 'Plot', width: 150, hidden: false, editable: true, editoptions: { size: 30} }, { name: 'ImageURL', index: 'ImageURL', width: 55, hidden: true, editable: false, editoptions: { readonly: true, size: 10} } ], pager: jQuery('#pager'), rowNum: 5, rowList: [5, 10, 20], sortname: 'id', sortorder: "desc", height: '100%', width: '100%', viewrecords: true, imgpath: '/Content/jqGridCss/redmond/images', caption: 'Movies from 2008', editurl: '/Home/EditMovieData/', caption: 'Movie List' }); }); $("#bedata").click(function() { var gr = jQuery("#editgrid").jqGrid('getGridParam', 'selrow'); if (gr != null) jQuery("#editgrid").jqGrid('editGridRow', gr, { height: 280, reloadAfterSubmit: false }); else alert("Hey dork, please select a row"); }); </script> The relevant HTML is here: <table id="editgrid"> </table> <div id="pager" style="text-align: center;"> </div> <input type="button" id="bedata" value="Edit Selected" />

• How do I know if I have an unmanaged resource?

  - by Shiftbit

  I've read that unmanaged resource are considered file handles, streams, anything low level. Does MSDN or any other source explain how to recognize an unmanaged resource? I can't seem to find any examples on the net that show unmanaged code, all the examples just have comments that say unmanaged code here. Can someone perhaps provide a realworld example where I would handle an unmanaged resources in an IDispose interface? I provided the IDisposable interface for your convience. How do I identify an unmanaged resource? Thanks in advance! IDisposable Reference Public Class Sample : Implements IDisposable Private disposedValue As Boolean = False 'To detect redundant calls ' IDisposable Protected Overridable Sub Dispose(ByVal disposing As Boolean) If Not Me.disposedValue Then If disposing Then ' TODO: free other state (managed objects). End If ' TODO: free your own state (unmanaged objects). ' TODO: set large fields to null. End If Me.disposedValue = True End Sub ' This code added by Visual Basic to correctly implement the disposable pattern. Public Sub Dispose() Implements IDisposable.Dispose ' Do not change this code. Put cleanup code in Dispose(ByVal disposing As Boolean) above. Dispose(True) GC.SuppressFinalize(Me) End Sub End Class

• How do I correctly install dulwich to get hg-git working on Windows?

  - by Joshua Flanagan

  I'm trying to use the hg-git Mercurial extension on Windows (Windows 7 64-bit, to be specific). I have Mercurial and Git installed. I have Python 2.5 (32-bit) installed. I followed the instructions on http://hg-git.github.com/ to install the extension. The initial easy_install failed because it was unable to compile dulwich without Visual Studio 2003. I installed dulwich manually by: git clone git://git.samba.org/jelmer/dulwich.git cd dulwich c:\Python25\python setup.py --pure install Now when I run easy_install hg-git, it succeeds (since the dulwich dependency is satisfied). In my C:\Users\username\Mercurial.ini, I have: [extensions] hgext.bookmarks = hggit = When I type 'hg' at a command prompt, I see: "* failed to import extension hggit: No module named hggit" Looking under my c:\Python25 folder, the only reference to hggit I see is Lib\site-packages\hg_git-0.2.1-py2.5.egg. Is this supposed to be extracted somewhere, or should it work as-is? Since that failed, I attempted the "more involved" instructions from the hg-git page that suggested cloning git://github.com/schacon/hg-git.git and referencing the path in my Mercurial configuration. I cloned the repo, and changed my extensions file to look like: [extensions] hgext.bookmarks = hggit = c:\code\hg-git\hggit Now when I run hg, I see: * failed to import extension hggit from c:\code\hg-git\hggit: No module named dulwich.errors. Ok, so that tells me that it is finding hggit now, because I can see in hg-git\hggit\git_handler.py that it calls from dulwich.errors import HangupException That makes me think dulwich is not installed correctly, or not in the path. Update: From Python command line: import dulwich yields Import Error: No module named dulwich However, under C:\Python25\Lib\site-packages, I do have a dulwich-0.5.0-py2.5.egg folder which appears to be populated. This was created by the steps mentioned above. Is there an additional step I need to take to make it part of the Python "path"?

• TinyMCE + jQuery + custom plugin = tinymce is undefined?

  - by user368691

  The problem occurs when I try to create small plugin to allow me toggle on and off WYSIWYG on all textareas in the website. //$('form.default textarea').each(function(){ // console.log( $('<a href="#">Enable WYSIWYG editor</a>').insertAfter('form.default textarea').prev('textarea.wysiwyg').tinymce().hide() ); //}); The full (a bit simplified) code looks like this: $('textarea.wysiwyg').tinymce({ skin : 'cirkuit', theme : 'advanced', plugins : 'pagebreak,style,layer,advlink,inlinepopups,contextmenu,paste,directionality,noneditable,nonbreaking,xhtmlxtras,template', // Theme options theme_advanced_buttons1 : 'formatselect,fontsizeselect,forecolor,|,bold,italic,strikethrough,|,bullist,numlist,|,justifyleft,justifycenter,justifyright,|,link,unlink,|,image,|,code,paste,pastetext,pasteword,removeformat,|,backcolor,|,underline,justifyfull,sup,|,outdent,indent,|,hr,charmap,|,undo,redo', theme_advanced_buttons2 : '', theme_advanced_buttons3 : '', theme_advanced_toolbar_location : 'top', theme_advanced_toolbar_align : 'left', theme_advanced_statusbar_location: 'bottom', theme_advanced_resizing : true, theme_advanced_resize_horizontal : false, height : 500, theme_advanced_resizing_min_height : 500, document_base_url : 'http://static.<?=$settings['system_host']?>/' }); $('textarea.wysiwyg').each(function() { $(this).tinymce().hide(); }); What is the error? FireBug says that tinymce() in undefined; this message occurs in each() loop. Thus, tinymce() is actually initialized. I am really lost towards, what could be causing this.

• Wordpress and Anythingslider Navigation Thumbnails

  - by Tom

  So I am using AnythingSlider in Wordpress. This is why I am trying to call the thumbnails from the original posts. Anything slider will configure thumbnail navigation like this: function formatText(index, panel) { return index + ""; } $(function () { $('.anythingSlider').anythingSlider({ navigationFormatter: formatText // Details at the top of the file on this use (advanced use) }); }); As you can see, the navigationFormatter will allow me to format the nav (including thumbnails) however I want. For example, to format thumbnails, I could do this: navigationFormatter : function(i, panel){ // add thumbnails as navigation links return '<img src="images/th-slide-' + ['civil-1', 'env-1', 'civil-2', 'env-2'][i - 1] + '.jpg">'; } So my issue is getting the wordpress slide images to show up there dynamically, rather than in a folder (as the above example shows). For reference, this is my php query that is pulling the posts image (from a script I've already written: <img class="slider-img" style="float:left;" src="<?php if(function_exists('wp_get_post_image')){ echo wp_get_post_image(array( 'return_html' => false, 'width' => 500 )); } ?>" /> I hope this update helps. Thank you guys so much. The Stack overflow community is great!

• Extracting bool from istream in a templated function

  - by Thomas Matthews

  I'm converting my fields class read functions into one template function. I have field classes for int, unsigned int, long, and unsigned long. These all use the same method for extracting a value from an istringstream (only the types change): template <typename Value_Type> Value_Type Extract_Value(const std::string& input_string) { std::istringstream m_string_stream; m_string_stream.str(input_string); m_string_stream.clear(); m_string_stream >> value; return; } The tricky part is with the bool (Boolean) type. There are many textual representations for Boolean: 0, 1, T, F, TRUE, FALSE, and all the case insensitive combinations Here's the questions: What does the C++ standard say are valid data to extract a bool, using the stream extraction operator? Since Boolean can be represented by text, does this involve locales? Is this platform dependent? I would like to simplify my code by not writing my own handler for bool input. I am using MS Visual Studio 2008 (version 9), C++, and Windows XP and Vista.

• HTML5 for IE6.0

  Hello! Do you know any method to optimize this HTML Code to IE6 or 7 (or 8) without adding any HTML elements, or the IE is skipping all the HTML5 elements? If i just want to format elements with CSS, - i dont want to use other features - is the document.createElement("nav") DOM element create enough to scam IE and make a plain HTML document? <!DOCTYPE HTML> <head> <meta charset="UTF-8"> <title>title</title> <link type="text/css" rel="stylesheet" href="reset.css"> <link type="text/css" rel="stylesheet" href="style.css"> </head> <body> <header>code of header</header> <nav> code of nav </nav> <section> code of gallery </section> <article> code of article </article> <footer>code of footer</footer> </body> </html> Thank you.

• Textbox autofill not in correct position in safari

  - by jerjer

  Hello All, Has anyone experience this weird issue on safari? Textbox autofill is not at its correct position, please see screenshot below. I have been searching for answers in google for almost a day, still no luck. This is the built-in autofill feature of safari. Here is the markup: index.php <html> <body> <div id="nav"></div> <div id="content"> <iframe style="width:100%;height:100%" src="add_user.php" frameborder="0"></iframe> </div> .... </body> </html> add_user.php <html> .... <body> <form method="post"> <h3>Add User (Admin only) <div id="msg">Please enter First and Last Name.</div> <ul> <li><label>* Email</label> <input type="text" id="email" /></li> <li><label>* First Name</label> <input type="text" id="fname" /></li> <li><label>* Last Name</label> <input type="text" id="lname" /></li> .... </ul> </form> </body> </html> I am suspecting that this is caused by the iframe, but it works just fine in other browsers. Also I could not change the page design(using iframe) right away for practical reasons. Thanks

• Best Practices for Setup and Management of an Open Source Project

  - by VirtuosiMedia

  Later this year I want to release a PHP framework that I've been working on as open source. I do use source control (SVN), but it's on an extremely limited basis. I'm self-taught, I develop by myself and don't have the experience of working with large teams. I have some ideas about what can help make a project successful, but I'm fuzzy on some of the details. Since it's not yet released, I want to do everything I can to set up the right infrastructure from the beginning. What do I need to know in order to setup and manage a successful project? Some ideas that I have to make it successful (beyond marketing it): Good documentation and tutorials Automated unit tests and builds to push update to the website A clear roadmap Bug Tracking integrated with the source control A style guide to keep the code consistent along with clear A forum for the community to get support, share ideas, etc. A good example application built with the framework A blog to keep the community informed Maintaining backwards compatibility wherever possible Some of my questions: How do I setup and automate a one step submit-test-commit-generate API docs-push update to website process? How do I handle (technically) submissions from other users? How can I ensure that those submissions must be approved before being integrated? What are some of the pitfalls that can be avoided in terms of the project community? I'd prefer to have it be as friendly and helpful as possible without a lot of drama. I'd love to learn from your experience on any of these points. If you think I'm missing anything big, please share that as well. Any resources (preferably geared toward a beginner) that you could point me towards would also be greatly appreciated.

• Is there a more useful explanation for UITableViewStylePlain?

  - by mystify

  From the docs: In the plain style, section headers and footers float above the content if the part of a complete section is visible. A table view can have an index that appears as a bar on the right hand side of the table (for example, "a" through "z"). You can touch a particular label to jump to the target section. I find that very hard to grasp. First, this one: if the part of a complete section is visible What do they mean by this? This is paradox. Which one is it? A) Table must be exactly the height of that section. If I have 5 Rows, and each row is 50px high, I must make it 5*50 high. The full section must be visible on the screen. Otherwise, if I have 100 rows but my table view is only 400 high, this will not apply. Nothing will float above my content. Sounds wrong. B) It doesn't matter how high my table view actually is. Header and Footer is floating above the content and I can scroll the section. Makes more sense. But is completely against this nonsense making sentence: 'if the part of a complete section is visible' Can anyone explain it better than they did?

• dojo.io.iframe erroring when uploading a file

  - by Grant Collins

  Hi, Hit an interesting problem today when trying to upload an image file < 2MB using dojo.io.iframe. My function to process the form is called, but before the form is posted to the server I am getting the following error: TypeError: ifd.getElementsByTagName("textarea")[0] is undefined My function that is used to action the post of the form is : function uploadnewlogo(){ var logoDiv = dojo.byId('userlogo'); var logoMsg = dojo.byId('uploadmesg'); //prep the io frame to send logo data. dojo.io.iframe.send({ url: "/users/profile/changelogo/", method: "post", handleAs: "text", form: dojo.byId('logoUploadFrm'), handle: function(data,ioArgs){ var response = dojo.fromJson(data); if(response.status == 'success'){ //first clear the image //dojo.style(logoDiv, "display", "none"); logoDiv.innerHTML = ""; //then we update the image logoDiv.innerHTML = response.image; }else if(response.status == 'error'){ logoMsg.innerHTML = data.mesg; }else{ logoMsg.innerHTML = '<div class="error">Whoops! We can not process your image.</div>'; } }, error: function(data, ioArgs){ logoMsg.innerHTML = '<div class="error">' + data + '</div>'; } }); } The form is very basic with just a File input component and a simple button that calls this bit of javascript and dojo. I've got very similar code in my application that uploads word/pdf documents and that doesn't error, but for some reason this does. Any ideas or pointers on what I should try to get this to work without errors? Oh I'm using php and Zend framework for the backend if that has anything to do with it, but I doubt it as it's not even hitting the server before it fails. Many thanks, Grant

• IE9 selectAllChildren on an out-of-view element

  - by MrSlayer

  I am trying to replicate a service that is provided by Tynt.com that appends some text to a user's selection when copying. I understand that users don't particularly like this, but it is a client's request to append the URL and copyright notice whenever a user copies something from their website. In current browsers, I am able to do this by creating a DOM element, adding the selected text, appending the copyright text and then selecting the new node: var newSelection = document.createElement( 'div' ); newSelection.style.cssText = "height: 1px; width: 1px; overflow: hidden;"; if( window.getSelection ) { var selection = window.getSelection( ); if( selection.getRangeAt ) { var range = selection.getRangeAt( 0 ); newSelection.appendChild( range.cloneContents( ) ); appendCopyright( ); document.body.appendChild( newSelection ); selection.selectAllChildren( newSelection ); // ... remove element, return selection } } In IE9, this errors out on the selection.selectAllChildren( newSelection ) statement and I was able to figure out that this is because newSelection was effectively "hidden" from the viewport due to the styles applied in the second line above. Commenting that out works, but obviously the new node is shown to the end user. It appears that this was resolved in later versions of IE, but I am having trouble coming up with a workaround that is sufficient for IE9, a browser that I need to support. I've tried a variety of alternatives, like setting visibility: hidden;, positioning it off-screen, and trying some alternative selection functions, but they each present different problems. The error thrown by IE is: SCRIPT16389: Unspecified error.

• Why doesn't every class in the .Net framework have a corresponding interface?

  - by Thorsten Lorenz

  Since I started to develop in a test/behavior driven style, I appreciated the ability to mock out every dependency. Since mocking frameworks like Moq work best when told to mock an interface, I now implement an interface for almost every class I create b/c most likely I will have to mock it out in a test eventually. Well, and programming to an interface is good practice, anyways. At times, my classes take dependencies on .Net classes (e.g. FileSystemWatcher, DispatcherTimer). It would be great in that case to have an interface, so I could depend on an IDispatcherTimer instead, to be able to pass it a mock and simulate its behavior to see if my system under test reacts correctly. Unfortunately both of above mentioned classes do not implement such interfaces, so I have to resort to creating adapters, that do nothing else but inherit from the original class and conform to an interface, that I then can use. Here is such an adapter for the DispatcherTimer and the corresponding interface: using System; using System.Windows.Threading; public interface IDispatcherTimer { #region Events event EventHandler Tick; #endregion #region Properties Dispatcher Dispatcher { get; } TimeSpan Interval { get; set; } bool IsEnabled { get; set; } object Tag { get; set; } #endregion #region Public Methods void Start(); void Stop(); #endregion } /// <summary> /// Adapts the DispatcherTimer class to implement the <see cref="IDispatcherTimer"/> interface. /// </summary> public class DispatcherTimerAdapter : DispatcherTimer, IDispatcherTimer { } Although this is not the end of the world, I wonder, why the .Net developers didn't take the minute to make their classes implement these interfaces from the get go. It puzzles me especially since now there is a big push for good practices from inside Microsoft. Does anyone have any (maybe inside) information why this contradiction exists?

• Jquery $.get against ASP.NET MVC not working in Opera and Firefox

  - by codelove

  Let me first put the code snippets here. I am just using the ASP.NET MVC project Visual Studio creates out of the box. So I am just putting the snippets I added to it: Site.master's head section: <head runat="server"> <title><asp:ContentPlaceHolder ID="TitleContent" runat="server" /></title> <script src="../../Scripts/jquery-1.3.2.min.js" type="text/javascript"></script> <link href="../../Content/Site.css" rel="stylesheet" type="text/css" /> <script src="../../Scripts/test.js" type="text/javascript"></script> <script type="text/javascript">$(document).ready(ready);</script> </head> Content of test.js: function ready(){ $.get("/Home/TestAjax", ajaxResponse); } function ajaxResponse(data){ alert("got response from server: " + data); } Method in HomeController: public String TestAjax() { if (Request.IsAjaxRequest()) { return "Got ajax request!"; } else { return "Non-ajax request"; } } Now the problem I am seeing in Firefox 3.5.30729 (Firebug) is when the ajax request goes out, IIS 7 on the remote box sends Http 302 back, which does the redirect and forces another get request, but it is not asynchronous. Opera also doesn't work so I assume it is the same problem. However, above code works just fine in IE 8, Chrome, and Safari. On localhost all of the above browsers work as expected including Firefox and Opera -- they all receive "Got ajax request!" as the response from the server. Anybody have any ideas what's going on here and how to fix it? I am looking for a real solution or at least explanation as to what is going on and why.

• Obtaining information about executable code from exe/pdb

  - by Miro Kropacek

  Hello, I need to extract code (but not data!) from classic win32 exe/dll files. It's clear I can't do this only with extraction of code segment content (because code segment contains also the data -- jump tables for example) and that I need some help from compiler. *.map files are nice but they only contain addresses of functions, i.e. the safest thing I can do is to start at that address and to process until the first return / jump instruction (because part of the function could be mentioned data) *.pdb files are better but I'm not sure what tools to use to extract information like this -- I took a look at DbgHelp and DIA SDK, the latter one seems to be the right tool but it doesn't look very simple. So my question/questions: To your knowledge, it is possible to extract information about code/data position (address + length) only via DbgHelp? If the DIA SDK is the only way, any idea what should I call for getting information like that? (that COM stuff is pretty heavy) Is there any other way? Of course my concern is about Visual Studio, C/C++ source compilation in the first place. Thanks for any hint.

• Inline image and caption in article - conform caption's width to image's width

  - by Micah

  Here's my code: <div class="image"> <img src="image.jpg" alt="Image description" /> <p class="caption">This is the image caption</p> </div> Here's my CSS: .image { position: relative; float: right; margin: 8px 0 10px 10px; } .caption { font-weight: bold; color: #444666; } As is above, the caption will conform to the width of div.image. My problem is often the img varies in size, from 100px width to 250px width. I'd like to make the caption width conform to the corresponding width of the image, no matter the size. While I'd love for this to be more semantic as well, I'm not sure how easy it would be to switch p.caption with img. Of course, I'd prefer that method but am taking this a step at a time. Is there some jquery code that I can use to detect the width of the image and add that width as an inline style to the caption tag? Is there a better way to do this? I'm open to suggestions.

• Soft Paint Bucket Fill: Colour Equality

  - by Bart van Heukelom

  I'm making a small app where children can fill preset illustrations with colours. I've succesfully implemented an MS-paint style paint bucket using the flood fill argorithm. However, near the edges of image elements pixels are left unfilled, because the lines are anti-aliased. This is because the current condition on whether to fill is colourAtCurrentPixel == colourToReplace (the colours are RGB uints) I'd like to add a smoothing/treshold option like in Photoshop and other sophisticated tools, but what's the algorithm to determine the equality/distance between two colours? if (match(pixel(x,y), colourToReplace) setpixel(x,y,colourToReplaceWith) How to fill in match()? Here's my current full code: var b:BitmapData = settings.background; b.lock(); var from:uint = b.getPixel(x,y); var q:Array = []; var xx:int; var yy:int; var w:int = b.width; var h:int = b.height; q.push(y*w + x); while (q.length != 0) { var xy:int = q.shift(); xx = xy % w; yy = (xy - xx) / w; if (b.getPixel(xx,yy) == from) { b.setPixel(xx,yy,to); if (xx != 0) q.push(xy-1); if (xx != w-1) q.push(xy+1); if (yy != 0) q.push(xy-w); if (yy != h-1) q.push(xy+w); } } b.unlock(null);

• Why does my REST request return garbage data?

  - by Alienfluid

  I am trying to use LWP::Simple to make a GET request to a REST service. Here's the simple code: use LWP::Simple; $uri = "http://api.stackoverflow.com/0.8/questions/tagged/php"; $jsonresponse= get $uri; print $jsonresponse; On my local machine, running Ubuntu 10.4, and Perl version 5.10.1: farhan@farhan-lnx:~$ perl --version This is perl, v5.10.1 (*) built for x86_64-linux-gnu-thread-multi I can get the correct response and have it printed on the screen.

But on my host's machine to which I SSH into, I get garbage printed on the screen for the same exact code. I am assuming it has something to do with the encoding, but the REST service does not return the character set type in the response, so how do I force LWP::Simple to use the correct encoding?

Here's my code: // CPPFileIO.cpp : Defines the entry point for the console application. // #include "stdafx.h" #include <fstream> #include <conio.h> #include <iostream> #include <string> using namespace std; int _tmain(int argc, _TCHAR* argv[]) { ifstream infile; infile.open("input.txt", ifstream::in); if (infile.is_open()) { while (infile.good()) cout << (char) infile.get(); } else { cout << "Unable to open file."; } infile.close(); _getch(); return 0; } I have confirmed that the input.txt file is in the correct "working directory" by checking the value of argv[0]. The Open method just won't work. I'm also having trouble debugging- should I not be able to set a watch on "infile.good()" or "infile.is_open()"? I keep getting "Error: member function not present." EDIT: Updated code listing with full code from .CPP file. UPDATE: The file was NOT in the Current Working Directory. This is the directory where the project file is located. Moved it there and it works when debugging in VS.NET.

• wsdl return an array of complex types

  - by Anand

  hi, I have defined a web service that will return the data from my mysql data base. I have written the web service in php. Now I have defined a complex type as follows: $server->wsdl->addComplexType( 'Category', 'complexType', 'struct', 'all', '', array( 'category_parent_id' => array('name' => 'category_parent_id', 'type' => 'xsd:int'), 'category_child_id' => array('name' => 'category_child_id', 'type' => 'xsd:int'), 'category_list' => array('name' => 'category_list', 'type' => 'xsd:int') ) ); The above complex type is a row in a table in my database. Now my function must send an array of these rows so how do I achieve the same My code is as follows: require_once('./nusoap/nusoap.php'); $server = new soap_server; $server-configureWSDL('productwsdl', 'urn:productwsdl'); // Register the data structures used by the service $server-wsdl-addComplexType( 'Category', 'complexType', 'struct', 'all', '', array( 'category_parent_id' = array('name' = 'category_parent_id', 'type' = 'xsd:int'), 'category_child_id' = array('name' = 'category_child_id', 'type' = 'xsd:int'), 'category_list' = array('name' = 'category_list', 'type' = 'xsd:int') ) ); $server-register('getaproduct', // method name array(), // input parameters //array('return' = array('result' = 'tns:Category')), // output parameters array('return' = 'tns:Category'), // output parameters 'urn:productwsdl', // namespace 'urn:productwsdl#getaproduct', // soapaction 'rpc', // style 'encoded', // use 'Get the product categories' // documentation ); function getaproduct() { $conn = mysql_connect('localhost','root',''); mysql_select_db('sssl', $conn); $sql = "SELECT * FROM jos_vm_category_xref"; $q = mysql_query($sql); while($r = mysql_fetch_array($q)) { $items[] = array('category_parent_id'=$r['category_parent_id'], 'category_child_id'=$r['category_child_id'], 'category_list'=$r['category_list']); } return $items; } // Use the request to (try to) invoke the service $HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : ''; $server-service($HTTP_RAW_POST_DATA);

• javascript function won't stop looping - It's on a netsuite website

  - by Lauren

  I need to change the shipping carrier drop-down and shipping method radio button once via a javascript function, not forever. However, when I use this function, which executes when on the Review and Submit page when the order is < $5, it goes into an endless loop: function setFreeSampShipping(){ var options = document.forms['checkout'].shippingcarrierselect.getElementsByTagName('option'); for (i=0;i<options.length;i++){ if (options[i].value == 'nonups'){ document.forms['checkout'].shippingcarrierselect.value='nonups'; document.forms['checkout'].shippingcarrierselect.onchange(); document.location.href='/app/site/backend/setshipmeth.nl?c=659197&n=1&sc=4&sShipMeth=2035'; } } } It gets called from within this part of the function setSampPolicyElems() which you can see I've commented out to stop the loop: if (carTotl < 5 && hasSampp == 1) { /* if (document.forms['checkout'].shippingcarrierselect.value =='ups'){ setFreeSampShipping(); } */ document.getElementById('sampAdd').style.display="none"; document.getElementById("custbody_ava_webshiptype").value = "7";//no charge free freight if (document.getElementById("applycoupon")) { document.location.href='/app/site/backend/setpromocode.nl?c=659197&n=1&sc=4&kReferralCode=SAMPLE' } document.write("<div id='msg'><strong>Sample & Shipping:</strong></span> No Charge. (Your sample order is < $5.)</div>"); } To see the issue, go to the order review and submit page here: https://checkout.netsuite.com/s.nl?c=659197&sc=4&n=1 (or go to http://www.avaline.com, hit "checkout", and login) You can log in with these credentials: Email:[email protected] Pass:test03

• How to debug browser crash when running Silverlight app

  - by onedozenbagels

  I am on a team of three people who are developing a Silverlight application. On two of our developers' machines the app seems to randomly crash. It never crashes on the third developer's machine. The nature of the crash is that internet explorer just dies with an "Internet Explorer has stopped working" message. The problem details look like this: Problem Event Name: BEX Application Name: IEXPLORE.EXE Application Version: 8.0.6001.18882 Application Timestamp: 4b3ed243 Fault Module Name: StackHash_2cd8 Fault Module Version: 0.0.0.0 Fault Module Timestamp: 00000000 Exception Offset: 0024df00 Exception Code: c0000005 Exception Data: 00000008 OS Version: 6.0.6002.2.2.0.256.6 Locale ID: 1033 Additional Information 1: 2cd8 Additional Information 2: 0c337fa6c2057a9dbce1860c5e2d8315 Additional Information 3: e13b Additional Information 4: 5da012709e52526a1af19795dc4a33fd Then windows displays this message: "To help protect your computer, Data Execution Prevention has closed Internet Explorer." If I am attached to the app with the Visual Studio debugger the only information I get is this line in the output window: "The program '[2140] iexplore.exe: Silverlight' has exited with code -1073741819 (0xc0000005)." How should I go about debugging this problem? I'm not really sure where to start.

• Delegate within a delegate in VB.NET.

  - by Topdown

  I am trying to write a VB.NET alternative to a C# anonymous function. I wish to call Threading.SynchronizationContext.Current.Send which expects a delegate of type Threading.SendOrPostCallback to be passed to it. The background is here, but because I wish to both pass in a string to MessageBox.Show and also capture the DialogResult I need to define another delegate within. I am struggling with the VB.NET syntax, both from the traditional delegate style, and lambda functions. My go at the traditional syntax is below, but I have gut feeling it should be much simpler than this: Private Sub CollectMesssageBoxResultFromUserAsDelegate(ByVal messageToShow As String, ByRef wasCanceled As Boolean) wasCanceled = False If Windows.Forms.MessageBox.Show(String.Format("{0}{1}Please press [OK] to ignore this error and continue, or [Cancel] to stop here.", messageToShow), "Continue", Windows.Forms.MessageBoxButtons.OKCancel, Windows.Forms.MessageBoxIcon.Exclamation) = Windows.Forms.DialogResult.Cancel Then wasCanceled = True End If End Sub Private Delegate Sub ShowMessageBox(ByVal messageToShow As String, ByRef canceled As Boolean) Private Sub AskUserWhetherToCancel(ByVal message As String, ByVal args As CancelEventArgs) If args Is Nothing Then args = New System.ComponentModel.CancelEventArgs With {.Cancel = False} Dim wasCancelClicked As Boolean Dim firstDelegate As New ShowMessageBox(AddressOf CollectMesssageBoxResultFromUserAsDelegate) '…. Now what?? 'I can’t declare SendOrPostCallback as below: 'Dim myDelegate As New Threading.SendOrPostCallback(AddressOf firstDelegate) End Sub
