• Browsers (IE and Firefox) freeze when copying large amount of text

  - by Matt

  I have a web application - a Java servlet - that delivers data to users in the form of a text printout in a browser (text marked up with HTML in order to display in the browser as we want it to). The text does display in different colors, though most of it is black. One typical mode of operation is this: 1. User submits a form to request data. 2. Servlet delivers HTML file to browser. 3. User does CTRL+A to select all the text. 4. User does CTRL+C to copy all the text. 5. User goes to a text editor and does CTRL+V to paste the text. In the testing where I'm having this problem, step #2 successfully loads all the data - we wait for that to complete. We can scroll down to the end of what the browser loaded and see the end of the data. However, the browser freezes on step #3 (Firefox) or on step #4 (IE). Because step #2 finishes, I think it is a browser/memory issue, and not an issue with the web application. If I run queries to deliver smaller amounts of data (but after several queries we get the same data we would have above in one query) and copy/paste this text, the file I save it into ends up being about 8 MB. If I save the browser's displayed HTML to a file on my computer via File-Save As from the browser menu, it works fine and the file is about 22 MB. We've tried this on 2 different computers at work (both running Windows XP, with at least 2 GB of RAM and many GB of free disk space), using Firefox and IE. We also tried it on a home computer from a home network outside of work (thinking it might be our IT security software causing the problem), running Windows 7 using IE, and still had the problem. When I've done this, I can see whatever browser I'm using utilizing the CPU at 50%. Firefox's memory usage grows to about 1 GB; IE's stays in the several hundred MBs. We once let this run for half an hour, and it did not complete. I'm most likely going to modify the web app to have an option of delivering a plain text file for download, and I imagine that will get the users what they need. But for the mean time, and because I'm curious - and I don't like my application freezing people's browsers, does anyone have any ideas about the browser freezing? I understand that sometimes you just reach your memory limit, but 22 MB sounds to me like an amount I should be able to copy to the clipboard.

• Using PHP5s SOAP Client to send data to an ASP/.NET based SOAP server.

  - by user325143

  I am trying to write a snippet of PHP to connect to a third party's API via SOAP to enter some data into their database. The API requires me to pass several mandatory fields for every call (username, password, companyid, entitytype) in addition to the mandatory data fields. It also requires me to call the "ValidateEntity" funciton before calling the "CreateEntity" function. Documentation can be found here: http://wiki.agemni.com/Getting_Started/APIs/Database_API I have never worked with SOAP before, so I am very new to this. Here is what I have so far: error_reporting(E_ALL); ini_set('display_errors', '1'); $client = new SoapClient("http://agemni.com/AgemniWebservices/service1.asmx?WSDL", array('trace'=> true)); $options = array( 'username' => "myuser", 'password' => "mypassword", 'companyid' => myID, 'entitytype' => 2 ); $params = array( 'fname' => "John", 'lname' => "Doe", 'phone' => "859-333-3333", 'zip' => "40332", 'area id' => "12345", 'lead id' => "28222", 'contactdate' => "4/10/2010" ); $validate = $client->__soapCall("ValidateEntity", array($params), array($options)); $client->__soapCall("CreateEntity", array($params), array($options)); echo "<pre>"; var_dump($client-> __getLastRequestHeaders()); var_dump($client-> __getLastRequest()); var_dump($client-> __getLastResponseHeaders()); var_dump($client-> __getLastResponse()); var_dump($result); echo "</pre>"; Upon executing this code, I get the following error: Fatal error: Uncaught SoapFault exception: [Client] SOAP-ERROR: Encoding: object hasn't 'objecttype' property in /www/tmp/index-soap.php:24 Stack trace: #0 /www/tmp/index-soap.php(24): SoapClient->__soapCall('ValidateEntity', Array) #1 {main} thrown in /www/stealth/tmp/index-soap.php on line 24 I guess my question is.. am I even going about doing this the right way? I know this is a very broad question, but I appreciate any advice you can give me about making this work. Please let me know if you require more detail. Thanks!

• What is the proper method to stop loading a Flex Module before it has completely loaded?

  - by Michael Prescott

  I seem to recall that Loader.unload() could once be used to stop loading a swf before it had finished loading. I can no longer find documentation or the blog where I read this. Perhaps it was an unofficial feature. Anyhow, IModuleInfo, returned by ModuleManager.getModule() has an unload() method. If I want to halt loading a Flex Module that is in progress, do I just call iModuleInfo_instance.unload()?

• Most efficient way to draw circles for polygon outlines

  - by user146780

  I'm using OpenGL and was told I should draw circles at each vertex of my outline to get smoothness. I tried this and it works great. The problem is speed. It crippled my application to draw a circle at each vertex. I'm not sure how else to fix the anomaly of my outlines other than circles, but using display lists and trying with vertex array both were brutally slow. Thanks

• How to find out if a method exists in Obj-C when given an NSString

  - by Justin

  I have a method as an NSString *. If it exists, I want to call it, and if not, do nothing. SEL eventSelector = NSSelectorFromString(eventSelectorStr); if ([delegate respondsToSelector:eventSelector]) { [delegate performSelector:eventSelector]; [delegate adapterDidFinishAdRequest:self]; } else { // Does not implement selector } This code does not work, since NSSelectorFromString will register the string as a selector, so respondsToSelector:eventSelector will cause a crash because the selector is actually invalid.

• Div not filling width of floated container (css expert needed

  - by Rayden

  I know there are many variations of this question posted, but none I've found quite provide an answer that works for this case. I basically have two left floated divs. Inside those two divs are div headers and tabled content. I want the Div headers (Hour/Minute) to stretch to the width of the tabled content, but they only do this in FF and Chrome, not IE7. IE7 is my works official browser so the one I need it to work with the most. Here is the CSS: #ui-timepicker-div { padding:0.2em; } #ui-timepicker-hours { float:left; } #ui-timepicker-minutes { margin:0 0 0 0.2em; float:left; } .ui-timepicker .ui-timepicker-header { padding:0.2em 0; } .ui-timepicker .ui-timepicker-title { line-height:1.8em; text-align:center; } .ui-timepicker table { margin:0.15em 0 0 0; font-size:.9em; border-collapse:collapse; } .ui-timepicker td { padding:1px; width:2.2em; } .ui-timepicker th, .ui-timepicker td { border:0; } .ui-timepicker td a { display:block; padding:0.2em 0.3em 0.2em 0.5em; text-align:right; text-decoration:none; } Here is the HTML (did not include tabled content): <div style="position: absolute; top: 252.667px; left: 648px; z-index: 1; display: none;" class="ui-timepicker ui-widget ui-widget-content ui-helper-clearfix ui-corner-all" id="ui-timepicker-div"> <div id="ui-timepicker-hours"> <div class="ui-timepicker-header ui-widget-header ui-helper-clearfix ui-corner-all"> <div class="ui-timepicker-title">Hour</div> </div> <table class="ui-timepicker"> </table> </div> <div id="ui-timepicker-minutes"> <div class="ui-timepicker-header ui-widget-header ui-helper-clearfix ui-corner-all"> <div class="ui-timepicker-title">Minutes</div> </div> <table class="ui-timepicker"> </table> </div> </div>

• find: missing argument to -exec in bash script

  - by Mephi_stofel

  The following works fine when I type it exactly in the command line: find /<some_path>/{epson,epson_laser,epson_inkjet} -iname "*.ppd" -exec grep "\*ModelName\:" {} \; | sed 's/.*\"\(.*\)\"/\1/' However, when I try to call the following from a bash script I get find: missing argument to -exec'. I have also tried the following (in many variants): eval find "$1" -iname "*.ppd" -exec 'bash -c grep "\*ModelName\:" "$1" | sed "s/.*\"\(.*\)\"/\1/" \; as was mentioned in find-exec-echo-missing-argument-to-exec.

• How to break out of a loop depending on a CheckBox Checked value while the loop is running?

  - by Rayner Vaz

  Lets say I want to call a function repeatedly if the user selects a CheckBox named "repeat" but the calls to the function should stop as soon as the user 'unchecks' the CheckBox. I tried using the 'Checked', 'Click' and 'Tap' event of the CheckBox but once the loop starts, it does not sense any changes in the checkbox's state. I even tried using a loop inside another button's _Click method, but then that creates a lock on the Button's 'pressed' state. Any ideas/alternate suggestions?

• Visual Studio code generated when choosing to explicitly implement interface

  - by fearofawhackplanet

  Sorry for the vague title, but I'm not sure what this is called. Say I add IDisposable to my class, Visual Studio can create the method stub for me. But it creates the stub like: void IDisposable.Dispose() I don't follow what this syntax is doing. Why do it like this instead of public void Dispose()? And with the first syntax, I couldn't work out how to call Dispose() from within my class (in my destructor).

• Android - Retrieve all data from a SQLite table row

  - by Paul

  I have searched and cannot find an answer to my issue so i hope i am not completely barking up the wrong tree (so to speak). I am new to android and have started to create an app. My app on one screen creates and adds entries to a SQLite database using public class DatabaseHandler extends SQLiteOpenHelper and this all appears to work. I retrieve all the data and populate it into a grid, again this now works. My issue is I am unable to retrieve one complete line from the grid. I populate/display the grid with the following code. I have cut a lot out as the grid is made in stages, header, blank lines etc but the grid does display as I want. The id’s work as when I touch a line it displays its unique id. The onClick is right at the end and when I use getText() instead of getID() all it returns is the data in the labelDate. How do I retrieve all the labels as listed below? TextView labelDATE = new TextView(this); TextView labelCP = new TextView(this); TextView labelBG = new TextView(this); TextView labelQA = new TextView(this); TextView labelCN = new TextView(this); TextView labelKT = new TextView(this); TextView[] tvArray = {labelDATE, labelCP, labelBG, labelQA, labelCN, labelKT}; labelDATE.setText(re.getTime()); labelCP.setText(re.getCP()); labelBG.setText(re.getBG()); labelQA.setText(re.getQA()); labelCN.setText(re.getCN()); labelKT.setText(re.getKT()); for (TextView tv : tvArray) { tv.setTextColor(Color.WHITE); tv.setId(200+count); tr.setOnClickListener(this); tr.addView(tv); } //add this to the table row tl.addView(tr, new TableLayout.LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT)); public void onClick(View v) { if (v instanceof TableRow) { TableRow row = (TableRow) v; TextView child = (TextView) row.getChildAt(0); Toast toast = Toast.makeText(this, String.valueOf(child.getId()), Toast.LENGTH_SHORT); toast.show(); } } I can supply all the code for the grid creation if required. Thanks for any help.
