WPF UI Automation - AutomationElement.FindFirst fails when there are lots of elements

- by Orion Edwards

We've got some automated UI tests for our WPF app (.NET 4); these test use the UI Automation API's. We call AutomationElement.FindFirst to find a target element, and then interact with it. Example (pseudocode): var nameEquals = new PropertyCondition(AutomationElement.NameProperty, "OurAppWindow"); var appWindow = DesktopWindow.FindFirst(TreeScope.Children, nameEquals); // this succeeds var idEquals = new PropertyCondition(AutomationElement.AutomationIdProperty, "ControlId"); var someItem = appWindow.FindFirst(TreeScope.Descendants, idEquals); // this suceeds sometimes, and fails sometimes! The problem is, the appWindow.FindFirst will sometimes fail and return null, even when the element is present. I've written a helper function which walks the UI automation tree manually and prints it out, and the element with the correct ID is present in all cases. It seems to be related to how many other items are also being displayed in the window. If there are no other items then it always succeeds, but when there are many other complex UI elements being displayed alongside it, then the find fails. I can't find any documented element limit mentioned for any of the automation API's - is there some way around this? I'm thinking I might have to write my own implemententation of FindFirst which does the tree walk manually itself... As far as I can tell this should work, because my tree-printer utility function does exactly that, and it's ok, but it seems like this would be unnecessary and slow :-( Any help would be greatly appreciated

Opening href in jQuery Dialog

- by Phil

Okay, so I've got the following code to create a dialog of a div within a page: $('#modal').dialog({ autoOpen: false, width: 600, height: 450, modal: true, resizable: false, draggable: false, title: 'Enter Data', close: function() { $("#modal .entry_date").datepicker('hide'); } }); $('.modal').click(function() { $('#modal').dialog('open'); }); All working fine. But what I want is to also be able to open a link in a dialog window, kinda like... <a href="/path/to/file.html" class="modal">Open Me!!</a> I've done this before by hardcoding the path: $('#modal').load('/path/to/file.html').dialog('open'); but we can't hardcode the path in the javascript (as there will be multiple coming from the database) and I'm struggling to understand how to get this to work. I'm also pretty sure that the answer is really obvious, and I'm merely setting myself up to be humbled by the clever folk here at StackOverflow, but I've scratched my head for long enough this afternoon, so my ego has been put away, and hopefully someone can point me in the right direction... Thanks Phil

Lambdas within Extension methods: Possible memory leak?

- by Oliver

I just gave an answer to a quite simple question by using an extension method. But after writing it down i remembered that you can't unsubscribe a lambda from an event handler. So far no big problem. But how does all this behave within an extension method?? Below is my code snipped again. So can anyone enlighten me, if this will lead to myriads of timers hanging around in memory if you call this extension method multiple times? I would say no, cause the scope of the timer is limited within this function. So after leaving it no one else has a reference to this object. I'm just a little unsure, cause we're here within a static function in a static class. public static class LabelExtensions { public static Label BlinkText(this Label label, int duration) { Timer timer = new Timer(); timer.Interval = duration; timer.Tick += (sender, e) => { timer.Stop(); label.Font = new Font(label.Font, label.Font.Style ^ FontStyle.Bold); }; label.Font = new Font(label.Font, label.Font.Style | FontStyle.Bold); timer.Start(); return label; } }

C# Regex replace url

- by Martijn

I have a bunch of links in a document which has to be replaced by a javascript call. All the links looks the same: <a href="http://domain/ViewDocument.aspx?id=3D1&doc=form" target="_blank">Document naam 1</a> <a href="http://domain/ViewDocument.aspx?id=3D2&doc=form" target="_blank">Document naam 2</a> <a href="http://domain/ViewDocument.aspx?id=3D3&doc=form" target="_blank">Document naam 3</a> Now I want all this links to be replaced to: <a href="javascript:loadDocument('1','form')">Document naam 1</a> <a href="javascript:loadDocument('2','form')">Document naam 2</a> <a href="javascript:loadDocument('3','form')">Document naam 3</a> So the Id=3D in the url is the first parameter in the function and the doc parameter is the second parameter in the function call. I want to do this using Regex because I think this is the quickest way. But the problem is my regex knowledge is too limited

jQuery getJSON request returning empty on a valid request

- by mikemike

I'm trying to grab some JSON from Apple's iTunes JSON service. The request is simple: http://ax.phobos.apple.com.edgesuite.net/WebObjects/MZStoreServices.woa/wa/wsSearch?term=jac&limit=25 If you visit the URL in your browser you will see some well-formed (backed up by jsonlint.com) JSON. When I use the following jQuery to make the request, however, the request finds nothing: $("#soundtrack").keypress(function(){ $.getJSON("http://ax.phobos.apple.com.edgesuite.net/WebObjects/MZStoreServices.woa/wa/wsSearch",{'term':$(this).val(), 'limit':'25'}, function(j){ var options = ''; for (var i = 0; i < j.results.length; i++) { options += '<option value="' + j.results[i].trackId + '">' + j.results[i].artistName + ' - ' + j.results[i].trackName + '</option>'; } $("#track_id").html(options); }); }); Firebug sees the request, but only receives an empty response. Any help would be appreciated here, as I'm at my whits end trying to solve it. You can view the script here: http://rnmtest.co.uk/gd/drives_admin/add_drive (soundtrack input box is at the bottom of the page). Thanks

Unmanaged DLL in C# Web Service

- by Telis

Hi Guys, please help µe as I am new into accessing an unmanaged DLL from C#.. I have a large unmanaged DLL in C++ and I am trying to access the DLL's classes and functions from a C# Web Service. I have seen many examples how to use DLLImport, but for some reason I am stuck with my very first wrapper method spending many hours with no luck.. What should I do to return an object in my 'Marshaled' [DllImport..] function? I would like to do something like that: [DllImport("unmanaged.dll")] public static extern MyClass MyFunction(); Here is the definition of my C++ class and the function that I want to access: class __declspec(dllexport) TPDate { public: TPDate(); TPDate(const TPDate& rhs); ... //today's date. static TPDate AsOfDate(void); ... } In my Web service I have declared the following StructLayout: [StructLayout(LayoutKind.Sequential)] public class TPDate { public TPDate(TPDate d) { _tpDate = d; } public TPDate _tpDate; } and here's where I think that I'm not doing something right: class WrapperTPDate { [DllImport("TPTools.dll", ExactSpelling=false, EntryPoint = "?AsOfDate@TPDate@@SA?AV1@XZ", CallingConvention = CallingConvention.StdCall)] [return: MarshalAs(UnmanagedType.Struct)] **public static extern TPDate AsOfDate();**// HERE THERE IS PROBLEM }; I am calling the wrapper as follows from my WebMethod: [WebMethod] public void ConstructModel() { TPDate date1 = WrapperTPDate.AsOfDate();// Here I get exception TPDate date = new TPDate(date1); } The exception i am getting is: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Runtime.InteropServices.MarshalDirectiveException: Cannot marshal 'return value': Invalid managed/unmanaged type combination (this type must be paired with LPStruct or Interface). If I change it to LPSTRUCT, I am getting another exception: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt Could you please tell me where I'm doing wrong here Thanks

InvalidAuthenticityToken for JQuery despite setting authenticity token

- by user117046

I'm getting an InvalidAuthenticityToken despite adding in corresponding authenticity tokens in the jquery response. Is there an error in the code, or is there another, root problem? I appreciate any comments. Thanks! Using: Rails 2.3.3, Ruby 1.8.6, Webrick, JQuery 1.3.2 layout/networks.html.haml = token_tag = javascript_tag "window.AUTH_TOKEN = '#{form_authenticity_token}';" javascripts/application.js $(document).ready(function() { // All non-GET requests will add the authenticity token // if not already present in the data packet $(document).ajaxSend(function(event, request, settings) { if (typeof(window.AUTH_TOKEN) == "undefined") return; // <acronym title="Internet Explorer 6">IE6</acronym> fix for http://dev.jquery.com/ticket/3155 if (settings.type == 'GET' || settings.type == 'get') return; settings.data = settings.data || ""; settings.data += (settings.data ? "&" : "") + "authenticity_token=" + encodeURIComponent(window.AUTH_TOKEN); }); ajaxLinks(); }); The rendered html has: <input name="authenticity_token" type="hidden" value="ZaXj3ACQl+8JKtaDAUoxtSsqzEagSPyHbS25ai9qWCw=" /> <script type="text/javascript"> //<![CDATA[ window.AUTH_TOKEN = 'ZaXj3ACQl+8JKtaDAUoxtSsqzEagSPyHbS25ai9qWCw='; //]]> </script> and breakpointing through, shows that window.AUTH_TOKEN has been set. Any help to resolve this would be great.

openCV Won't copy to image after changed color ( opencv and c++ )

- by user1656647

I am a beginner at opencv. I have this task: Make a new image Put a certain image in it at 0,0 Convert the certain image to gray scale put the grayscaled image next to it ( at 300, 0 ) This is what I did. I have a class imagehandler that has constructor and all the functions. cv::Mat m_image is the member field. Constructor to make new image: imagehandler::imagehandler(int width, int height) : m_image(width, height, CV_8UC3){ } Constructor to read image from file: imagehandler::imagehandler(const std::string& fileName) : m_image(imread(fileName, CV_LOAD_IMAGE_COLOR)) { if(!m_image.data) { cout << "Failed loading " << fileName << endl; } } This is the function to convert to grayscale: void imagehandler::rgb_to_greyscale(){ cv::cvtColor(m_image, m_image, CV_RGB2GRAY); } This is the function to copy paste image: //paste image to dst image at xloc,yloc void imagehandler::copy_paste_image(imagehandler& dst, int xLoc, int yLoc){ cv::Rect roi(xLoc, yLoc, m_image.size().width, m_image.size().height); cv::Mat imageROI (dst.m_image, roi); m_image.copyTo(imageROI); } Now, in the main, this is what I did : imagehandler CSImg(600, 320); //declare the new image imagehandler myimg(filepath); myimg.copy_paste_image(CSImg, 0, 0); CSImg.displayImage(); //this one showed the full colour image correctly myimg.rgb_to_greyscale(); myimg.displayImage(); //this shows the colour image in GRAY scale, works correctly myimg.copy_paste_image(CSImg, 300, 0); CSImg.displayImage(); // this one shows only the full colour image at 0,0 and does NOT show the greyscaled one at ALL! What seems to be the problem? I've been scratching my head for hours on this one!!!

Need assistance with Kohana 3 and catch all route turning into a 404 error

- by alex

Based on this documentation, I've implemented a catch all route which routes to an error page. Here is the last route in my bootstrap.php Route::set('default', '<path>', array('path' => '.+')) ->defaults(array( 'controller' => 'errors', 'action' => '404', )); However I keep getting this exception thrown when I try and go to a non existent page Kohana_Exception [ 0 ]: Required route parameter not passed: path If I make the <path> segment optional (i.e. wrap it in parenthesis) then it just seems to load the home route, which is... Route::set('home', '') ->defaults(array( 'controller' => 'home', 'action' => 'index', )); The home route is defined first. I execute my main request like so $request = Request::instance(); try { // Attempt to execute the response $request->execute(); } catch (Exception $e) { if (Kohana::$environment === Kohana::DEVELOPMENT) throw $e; // Log the error Kohana::$log->add(Kohana::ERROR, Kohana::exception_text($e)); // Create a 404 response $request->status = 404; $request->response = Request::factory(Route::get('default')->uri())->execute(); } $request->send_headers(); echo $request->response; This means that the 404 header is sent to the browser, but I assumed by sending the request to the capture all route then it should show the 404 error set up in my errors controller. <?php defined('SYSPATH') or die('No direct script access.'); class Controller_Errors extends Controller_Base { public function before() { parent::before(); } public function action_404() { $this->bodyClass[] = '404'; $this->internalView = View::factory('internal/not_found'); $longTitle = 'Page Not Found'; $this->titlePrefix = $longTitle; } } Why won't it show my 404 error page?

Gmail like URL scheme

- by Varun

I am working on a ticket system, having the following requirement: The home page is divided into two sections: Sec-1. Some filter options are shown here.(like closed-tickets, open-tickets, all-tickets, tickets-assigned-to-me etc.). You can select one or more of these filters. sec-2. List of tickets satisfying above filters will be displayed here. Now this is what I want: As I change the filters -- the change should be reflected in the URL, so that one is able to bookmark it. -- an ajax request will go and list of tickets satisfying the selected filters will be updated in sec-2. I want the same code to be used to load the tickets in both ways- (a) by selecting that set of filters and (b) by using the bookmark to reload the page. I have little idea on how to do it: The URL will contain the selected filters.(appended after #) changing filters on the page will modify the hash part of URL and call a function (say ajaxHandler()) to parse the URL to get the filters and then make an ajax request to get the list of tickets to be displayed in section2. and I will call the same function ajaxHandler() in window.onload. I feel this is what Yahoo maps does. What's the best way to implement such URL scheme? Am I headed in the right direction?

Creating A Single Generic Handler For Agatha?

- by David

I'm using the Agatha request/response library (and StructureMap, as utilized by Agatha 1.0.5.0) for a service layer that I'm prototyping, and one thing I've noticed is the large number of handlers that need to be created. It generally makes sense that any request/response type pair would need their own handler. However, as this scales to a large enterprise environment that's going to be A LOT of handlers. What I've started doing is dividing up the enterprise domain into logical processor classes (dozens of processors instead of many hundreds or possibly eventually thousands handlers). The convention is that each request/response type (all of which inherit from a domain base request/response pair, which inherit from Agatha's) gets exactly one function in a processor somewhere. The generic handler (which inherits from Agatha's RequestHandler) then uses reflection in the Handle method to find the method for the given TREQUEST/TRESPONSE and invoke it. If it can't find one or if it finds more than one, it returns a TRESPONSE containing an error message (messages are standardized in the domain's base response class). The goal here is to allow developers across the enterprise to just concern themselves with writing their request/response types and processor functions in the domain and not have to spend additional overhead creating handler classes which would all do exactly the same thing (pass control to a processor function). However, it seems that I still need to have defined a handler class (albeit empty, since the base handler takes care of everything) for each request/response type pair. Otherwise, the following exception is thrown when dispatching a request to the service: StructureMap Exception Code: 202 No Default Instance defined for PluginFamily Agatha.ServiceLayer.IRequestHandler`1[[TSFG.Domain.DTO.Actions.HelloWorldRequest, TSFG.Domain.DTO, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]], Agatha.ServiceLayer, Version=1.0.5.0, Culture=neutral, PublicKeyToken=6f21cf452a4ffa13 Is there a way that I'm not seeing to tell StructureMap and/or Agatha to always use the base handler class for all request/response type pairs? Or maybe to use Reflection.Emit to generate empty handlers in memory at application start just to satisfy the requirement? I'm not 100% familiar with these libraries and am learning as I go along, but so far my attempts at both those possible approaches have been unsuccessful. Can anybody offer some advice on solving this, or perhaps offer another approach entirely?

Concurrent cartesian product algorithm in Clojure

- by jqno

Is there a good algorithm to calculate the cartesian product of three seqs concurrently in Clojure? I'm working on a small hobby project in Clojure, mainly as a means to learn the language, and its concurrency features. In my project, I need to calculate the cartesian product of three seqs (and do something with the results). I found the cartesian-product function in clojure.contrib.combinatorics, which works pretty well. However, the calculation of the cartesian product turns out to be the bottleneck of the program. Therefore, I'd like to perform the calculation concurrently. Now, for the map function, there's a convenient pmap alternative that magically makes the thing concurrent. Which is cool :). Unfortunately, such a thing doesn't exist for cartesian-product. I've looked at the source code, but I can't find an easy way to make it concurrent myself. Also, I've tried to implement an algorithm myself using map, but I guess my algorithmic skills aren't what they used to be. I managed to come up with something ugly for two seqs, but three was definitely a bridge too far. So, does anyone know of an algorithm that's already concurrent, or one that I can parallelize myself?

Finding the last focused element with jQuery.

- by Joshua Cody

I'm looking to determine which element had the last focus in a series of inputs, that are added dynamically by the user. This code can only get the inputs that are available on page load: $('input.item').focus(function(){ $(this).siblings('ul').slideDown(); }); And this code sees all elements that have ever had focus: $('input.item').live('focus', function(){ $(this).siblings('ul').slideDown(); }); The HTML structure is this: <ul> <li><input class="item" name="goals[]"> <ul> <li>long list here</li> <li>long list here</li> <li>long list here</li> </ul></li> </ul> <a href="#" id="add">Add another</a> On page load, a single input loads. Then with each add another, a new copy of the top unordered list's contents are made and appended. And when each gets focus, I'd like to show the list beneath it. But I don't seem to be able to "watch for the most recently focused element, which exists now or in the future." Do I have some sort of fundamental assumption wrong?

Why does this code send the form input to the URL?

- by marcamillion

How do I get this form input to be stored in a variable, that I can then use later - rather than being appended to the end of the URL? <script type="text/javascript"> $(function() { var tag_box = $("<div>").appendTo("body").css({ "width": "40px", "height":"40px", "border":"4px solid #000000", "position":"absolute", "display":"none", "padding":"15px" }); var comment_box = $("<form action='#'><input id='comment' type='text' name='comment' placeholder='Add comment'></form>").appendTo(tag_box).css({"position":"absolute"}); $("#image-wrapper").live("click", function(e) { tag_box.css({ "left": e.pageX - 40, "top": e.pageY - 40, "display": "block" }) .after(comment_box.css({ "left": e.pageX - 65, "top": e.pageY + 40 })); return false; }); }); </script> <body> <div align="center"> <img src="images/ror1.gif" width="760" height="182" alt="Ror1" id="image-wrapper"> </div> </body>

NSIS takes ownership of IIS system files

- by Lucas

I recently encountered an issue with NSIS that I believe is related to an interaction with UAC, but I am at a loss to explain it and I do not know how to prevent it in the future. I have an installer that creates and removes IIS virtual directories using the NsisIIS plugin. The installer appeared worked correctly on my Windows 7 workstation. When the installer was run on a Windows 2008 R2 server it installed properly, but the uninstaller removed all of the virtual directories and put IIS is an unusable state; to the point that I had to remove the Default Web Site and re-add it. What I eventually found was that all of the IIS configuration files under C:\Windows\System32\inetsrv\config had a lock icon on them. Some investigation seem to indicate that this means a user account has taken ownership of the file, however all the files listed SYSTEM as the file owner. I did check a different server that I have not run the installer on, and it does not have the lock icon applied to the IIS files. I have also seen the same lock icon appear on other files that the NSIS installer creates. For instance, I have a Web.Config.tpl file that is processed using the NSIS ReplaceInFile which also appears with the lock icon after the installer finished. After I explicitly grant another user account access to the file, the lock icon goes away. I run the installer under the local Administrator account on the 2008 R2 server, so I do not get the UAC prompt. Here is the relevant code from the install.nsi file RequestExecutionLevel admin Section "Application" APP_SECTION SectionIn RO Call InstallApp SectionEnd Section "un.Uninstaller Section" Delete "$PROGRAMFILES\${PROGRAMFILESDIR}\Uninstall.exe" Call un.InstallApp SectionEnd Function InstallApp File /oname=Web.Config Web.Config.tpl !insertmacro ReplaceInFile Web.Config %CONNECTION_STRING% $CONNECTION_STRING FunctionEnd Function un.InstallApp ReadRegStr $0 HKLM "Software\${REGKEY}" "VirtualDir" NsisIIS::DeleteVDir "$0" Pop $0 FunctionEnd I have three questions stemming from this incident: How did this happen? How can I fix my installer to prevent it from happening again? How can I repair the permissions on the IIS config files.

Loading JSON-encoded AJAX content into jQuery UI tabs

- by pocketfullofcheese

We want our of our AJAX calls in our web app to receive JSON-encoded content. In most places this is already done (e.g. in modals) and works fine. However, when using jQueryUI's tabs (http://jqueryui.com/demos/tabs/) and their ajax functionality, only plaintext HTML can be returned (i.e. from the URLs specified in the a tags below). How do I get the tab function to recognize that on each tab's click, it will be receiving JSON-encoded data from the specified URL, and to load in the .content index of that JSON? $(function() { $('div#myTabs').tabs(); }); <div id="mytabs" class="ui-tabs ui-widget ui-widget-content ui-corner-all"> <ul class="ui-tabs-nav ui-helper-reset ui-helper-clearfix ui-widget-header ui-corner-all"> <li class="ui-state-default ui-corner-top"><a href="/url/one">Tab one</a></li> <li class="ui-state-default ui-corner-top"><a href="/url/two">Tab two</a></li> </ul> </div>

Canvas rotate from bottom center image angle?

- by Tom

How do you rotate an image with the canvas html5 element from the bottom center angle? See http://uptowar.com/test.php for my current code and image: <html> <head> <title>test</title> <script type="text/javascript"> function startup() { var canvas = document.getElementById('canvas'); var ctx = canvas.getContext('2d'); var img = new Image(); img.src = 'player.gif'; img.onload = function() { ctx.translate(185, 185); ctx.rotate(90 * Math.PI / 180); ctx.drawImage(img, 0, 0, 64, 120); } } </script> </head> <body onload='startup();'> <canvas id="canvas" style="position: absolute; left: 300px; top: 300px;" width="800" height="800"></canvas> </body> </html> Unfortunately this seems to rotate it from the top left angle of the image. Any idea? Edit: in the end the object (space ship) has to rotate like a clock pointer, as if it is turning right/left.

Why I am getting a Heap Corruption Error?

- by vaidya.atul

I am new to C++. I am getting HEAP CORRUPTION ERROR. Any help will be highly appreciated. Below is my code class CEntity { //some member variables CEntity(string section1,string section2); CEntity(); virtual ~CEntity(); //pure virtual function .. virtual CEntity* create()const =0; }; I derive CLine from CEntity as below class CLine:public CEntity { // Again some variables ... // Constructor and destructor CLine(string section1,string section2); CLine(); ~CLine(); CLine* Create() const; } // CLine Implementation CLine::CLine(string section1,string section2):CEntity(section1,section2){}; CLine::CLine(); CLine* CLine::create()const{return new CLine();} I have another class CReader which uses CLine object and populates it in a multimap as below class CReader { public: CReader(); ~CReader(); multimap<int,CEntity*>m_data_vs_entity; }; //CReader Implementation CReader::CReader() { m_data_vs_entity.clear(); }; CReader::~CReader() { multimap<int,CEntity*>::iterator iter; for(iter = m_data_vs_entity.begin();iter!=m_data_vs_entity.end();iter++) { CEntity* current_entity = iter->second; if(current_entity) delete current_entity; } m_data_vs_entity.clear(); } I am reading the data from a file and then populating the CLine Class.The map gets populated in a function of CReader class. Since CEntity has a virtual destructor, I hope the piece of code in CReader's destructor should work. In fact, it does work for small files but I get HEAP CORRUPTION ERROR while working with bigger files. If there is something fundamentally wrong, then, please help me find it, as I have been scratching my head for quit some time now. Thanks in advance and awaiting reply, Regards, Atul

Trouble move-capturing std::unique_ptr in a lambda using std::bind

- by user2478832

I'd like to capture a variable of type std::vector<std::unique_ptr<MyClass>> in a lambda expression (in other words, "capture by move"). I found a solution which uses std::bind to capture unique_ptr (http://stackoverflow.com/a/12744730/2478832) and decided to use it as a starting point. However, the most simplified version of the proposed code I could get doesn't compile (lots of template mistakes, it seems to try to call unique_ptr's copy constructor). #include <functional> #include <memory> std::function<void ()> a(std::unique_ptr<int>&& param) { return std::bind( [] (int* p) {}, std::move(param)); } int main() { a(std::unique_ptr<int>(new int())); } Can anybody point out what is wrong with this code? EDIT: tried changing the lambda to take a reference to unique_ptr, it still doesn't compile. #include <functional> #include <memory> std::function<void ()> a(std::unique_ptr<int>&& param) { return std::bind( [] (std::unique_ptr<int>& p) {}, // also as a const reference std::move(param)); } int main() { a(std::unique_ptr<int>(new int())); }

Problem in IE8 with GET Parameters in opening a new windows with javascript.

- by amfa95

Hi, I have a problem with IE8 and the opening of a new window with javascript and submitting parameters with special characters. <a href="javascript:oWin('/html/de/4664286/printregistrationcontent.html?12-security question=Wie heißt Ihr Lieblingsrestaurant','PRINT',800,600);" class="print">Seite drucken</a> The Problem is the letter 'ß' (sharp S). As you can see the string above is encodes due to anti XSS. This link works in FF and IE6 but IE8 is transmitting the URL Parameter as character with code 65*** (don't know the exaxt value). In the opening window you will only see a square (because character with 65000+ is not printable). I also tried to use URL Encoding instead of HTML encoding <a href="javascript:oWin('/html/de/4664286/printregistrationcontent.html?12-security question%3DWie hei%C3%9Ft Ihr Lieblingsrestaurant','PRINT',800,600);" class="print">Seite drucken</a> If i click on this Link in FF or IE6 it works as expected, but IE8 will fail to transmit the "ß" to the server and therefor will also get it back in the wrong way. If i paste this url to the IE8 it will work too, but not if the window is opened by javascript. The Javascript function oWin is defined as follows function oWin(url,title,sizeH,sizeV) { winHandle = top.open(url,title,'toolbar=no,directories=no,status=yes,scrollbars=yes,menubar=no,resizable=no,width='+sizeH+',height='+sizeV); if(navigator.appVersion.indexOf("MSIE 3",0)==-1) id = setTimeout('winHandle.focus()',1000); } If someone has an idea where to look for the reason please answer to this. Thank you amfa

Loading GMaps via ajax

- by Marco

Hi to all, I'm loading a page containing a GMaps using the ajax() method of jQuery. The HTML page i'm loading is: <script src="http://maps.google.com/maps?file=api&v=2&sensor=false&key=MY_API_KEY" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function() { if (GBrowserIsCompatible()) { var map = new GMap2(document.getElementById("map_canvas")); var geocoder = new GClientGeocoder(); geocoder.getLatLng("San Francisco, California",function(point) { if (point) { map.setCenter(point, 7); } }); map.setUIToDefault(); } }); </script> <div id="map_canvas"></div> After retrieving this page, I'm setting its contents to a div using the html() method. The map is not showed, while other pages containing scripts, loaded in the same way, are correctly shown. Is this a specific issue about GMaps, that doesn't allow to be loaded via an ajax request? Thanks

Javascript add a PHP file.

- by Jordan Pagaduan

var editing = false; if (document.getElementById && document.createElement) { var butt = document.createElement('BUTTON'); var buttext = document.createTextNode('Ready!'); butt.appendChild(buttext); butt.onclick = saveEdit; } function catchIt(e) { if (editing) return; if (!document.getElementById || !document.createElement) return; if (!e) var obj = window.event.srcElement; else var obj = e.target; while (obj.nodeType != 1) { obj = obj.parentNode; } if (obj.tagName == 'TEXTAREA' || obj.tagName == 'A') return; while (obj.nodeName != 'P' && obj.nodeName != 'HTML') { obj = obj.parentNode; } if (obj.nodeName == 'HTML') return; var x = obj.innerHTML; var y = document.createElement('TEXTAREA'); var z = obj.parentNode; z.insertBefore(y,obj); z.insertBefore(butt,obj); z.removeChild(obj); y.value = x; y.focus(); editing = true; } function saveEdit() { var area = document.getElementsByTagName('TEXTAREA')[0]; var y = document.createElement('P'); var z = area.parentNode; y.innerHTML = area.value; z.insertBefore(y,area); z.removeChild(area); z.removeChild(document.getElementsByTagName('button')[0]); editing = false; } document.onclick = catchIt; This code is a quick edit and I want to add a PHP script that will UPDATE my database base on the changes on the text.

emacs tramp performance

- by Oleg Pavliv

Is there a way to improve emacs tramp performance? For me it's faster to open an external ftp client (filezilla), transfer files to the local disk and open them in an external editor (notepad) than open them with emacs. I use emacs23.1 under windows xp. I tried different tramp-default-method (telnet, pscp, ftp), all of them have the same performance. Profiling results with elp-instrument-package are the following (I opened 3 remote files of 1.5 MB each one) tramp-file-name-handler 1461 350.41599999 0.2398466803 tramp-sh-file-name-handler 1461 350.02699999 0.2395804243 tramp-send-command 227 179.63400000 0.7913392070 tramp-send-command-and-check 205 177.77600000 0.8672000000 tramp-wait-for-regexp 227 176.47800000 0.7774361233 tramp-wait-for-output 226 176.40000000 0.7805309734 tramp-barf-unless-okay 18 133.46699999 7.4148333333 tramp-handle-insert-file-contents 3 132.046 44.015333333 tramp-handle-file-local-copy 3 131.281 43.760333333 tramp-accept-process-output 2375 112.95100000 0.0475583157 So, actual file transfer takes 132 sec, about 1/3 of total time. Why does it spend so much time in tramp-sh-file-name-handler? I tried to advice a function tramp-sh-file-name-handler to store and return cached results but it does not work, probably this function has some side effects. Any ideas how to improve tramp performance? (I use emacs 23.1 under WindowsXP)
