• GWT application throws an exception when run on Google Chrome with compiler output style set to 'OBF

  - by Elifarley

  I'd like to know if you guys have faced the same problem I'm facing, and how you are dealing with it. Sometimes, a small and harmless change in a Java class ensues strange errors at runtime. These errors only happen if BOTH conditions below are true: 2) the application is run on Google Chrome, and 1) the GWT JavaScript compiler output style is set to 'OBF'. So, running the application on Firefox or IE always works. Running with the output style set to 'pretty' or 'detailed' always works, even on Google Chrome. Here's an example of error message that I got: "((TypeError): Property 'top' of object [object DOMWindow] is not a function stack" And here's what I have: - GWT 1.5.3 - GXT 1.2.4 - Google Chrome 4 and 5 - Windows XP In order to get rid of this Heisenbug, I have to either deploy my application without obfuscation or endure a time-consuming trial-and-error process in which I re-implement the change in slightly different ways and re-run the application, until the GWT compiler is happy with my code. Would you have a better idea on how to avoid this?

• StackOverflow Site Layout Problem in Chrome

  - by Laramie

  I was cleaning up one of my questions here and noticed that Stack Overflow's comments were overflowing into the right column in Chrome. The question is, what's the difference in CSS handling between Chrome and Firefox. I don't have access to Safari, Opera, et al. Can someone tell me in which browsers the error manifests? Is it just me? Here's the layout error: (my apologies to Tim Down for covering up his name with my comment bubble) Since I have no natural skill for good layouts and the whole process makes me sad, I wonder if someone can diagnose the error on StackOverflow and make a recommendation on how to avoid it. Is this a consequence of embedding a div inside a td? Plus I admit it. It's fun to point out an error on one of the greatest sites ever.

• Find the xmlHttpRequest resource in aspx page

  - by DJStroky

  I'm trying to find an xmlHttpRequest or similar resource that I can query directly to obtain an xml file for my own purposes. At this site it is possible to browse a Google Map mashup with markers. Unfortunately it is only possible to view all markers at a small view range, whereas I simply want to obtain all the information at once for the entire state. Using the firebug console in firefox I can enter the following javascript line to obtain the xml that I desire: document.getElementById("stationXML").value I tracked this document element down to an <input> tag, but I can't figure out how that input is set. Thanks in advance for your help!

• IIS7 - Specifying content-length header in ASP causes "connection reset" error

  - by MisterZimbu

  I'm migrating a series of websites from an existing IIS5 server to a brand new IIS7 web server. One of the pages pulls a data file from a blob in the database and serves it to the end user: Response.ContentType = rs("contentType") Response.AddHeader "Content-Disposition", "attachment;filename=" & Trim(rs("docName"))&rs("suffix")' let the browser know the file name Response.AddHeader "Content-Length", cstr(rs("docsize"))' let the browser know the file size Testing this in the new IIS7 install, I get a "Connection Reset" error in both Internet Explorer and Firefox. The document is served up correctly if the Content-Length header is removed (but then the user won't get a useful progress bar). Any ideas on how to correct this; whether it be a server configuration option or via code? Thanks.

• [ASP.NET] IIS7 downloading file length

  - by GTD

  I've following code for file download: FileInfo fileInfo = new FileInfo(filePath); context.Response.Clear(); context.Response.ContentType = "application/octet-stream"; context.Response.AddHeader("Content-Disposition", "attachment; filename=" + System.IO.Path.GetFileName(filePath)); context.Response.AddHeader("Content-Length", fileInfo.Length.ToString()); context.Response.WriteFile(filePath); context.Response.End(); When I run it on my local IIS6 it works fine. Web browser (tested on IE8, Firefox 3.5.2, Opera 10) shows file length before I start download the file. When I run this code on remote IIS7, web browser doesn't shows file length. File length is unknown. Why I don't get file length when this code runs under IIS7?

• start .net application from start menu search

  - by BorisT

  bla.exe (application alias) points to a .net application called wpfapp1.exe. When i add a key&value to eg. this key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\bla.exe and then start application using Run - bla.exe it starts however when i start application using windows search i get an "windows cannot find wpfapp1.exe. make sure you typed the name correctly, and then try again." I have successfully identified problem: this error only occurs to .net applications while native one start normally (eg. firefox.exe). So is there any .net config that i've missed during development?

• Programmatically manipulating DOM element value doesn't fire onchange event

  - by Johan Fredrik Varen

  Hi all. I've got a hidden form field, and when a button gets pressed the value of the hidden field is changed. Now, I've added an observer to the hidden field, listening for changes to occur. For some reason, though, the event listener never kicks in, even though the value of the hidden element changes. I'm using Prototype and Firefox 3.6. The code looks roughly like this: button.observe('click', function(event) { hiddenField.setValue(someValue); }); hiddenField.observe('change', function(event) { alert('It works!'); }); Does anyone have a clue why the latter observer doesn't execute? Thanks!

• Mac dashboard widgets not loading external images

  - by andrhamm

  I set out to make a quick Mac OS X dashboard widget. I read the documentation and was pleased to find out they use simple HTML, JS, and CSS. I created my widget and it works when I open the .html file in Firefox, but it does not work when I install the widget to the dashboard. The widget is simple: it displays the most recent image from a weather web cam stream. The image URLs look like this: http://webcam.com/stream.jpg?1274213999617. The timestamp is appended to the URL and the server automatically responds with the latest image for that time. I did not write the server script. The widget appears to be loading correctly, but the web cam image will not load. Notice the blue question mark in the upper left. The image should appear over the square background image. Is there any special procedure for loading external images into a widget?

• datatables.net plugin hides table behind left menu

  - by naveen

  I had a page that works perfectly in IE. Then I added the wonderful jQuery plugin datatables.net to it using this code in DOMReady with this code $('#articlestable-container table').dataTable({ "bPaginate": true, "bLengthChange": false, "bFilter": true, "bSort": false, "bInfo": false, "bAutoWidth": false }); Everything is fine in Webkit and Firefox browsers. See the image. But in IE, the table hides the menu that ideally should come over the table like this. As you can see, the sub-menu gets rendered behind the table. I don't think z-index is the culprit here. The sub-menu has z-index: 9999; anyway. What could be wrong? Any pointers to solve this will be very helpful.

• visual studio localhost server can't locate file

  - by mhenk

  i have a very simple web project. just one htm file with some javascript that opens a file test.xml. the xml file is in the same folder as the htm file (and it is part of the project) but when i start the page (f5 or ctrl-f5) it can't find the xml. it starts as http://localhost:50586/main.htm when i do a folder list the test.xml file is right there. opening the page directly in firefox works fine and the script can read and extract data from the xml. how can i convince the development server that the xml is indeed there?? or better still: how can i turn the development server off entirely? for my purposes simply opening the page in my browser is all i need and that should happen from within vs of course.

• turning on Greasemonkey live editing

  - by Delirium tremens

  On Firefox, I click Tools, Addons, Extensions, Greasemonkey, Options, select my user script, click Edit, change the source code, reload one of the included pages, but the script is the unchanged version. On User Scripts, logged in, I click my username, Script Management, my script's name, Admin, Edit Code Online, change the source code, click save, the link to the install page, install and the script is the changed version. How did you turn on Live Editing? While following Greasemonkey tutorials, this feature is not working... Are you going to use the "works on my computer" excuse? Should this be on the Stack Overflow sister site Super User?

• webkit multiple inline shadows

  - by meo

  I have trouble setting multiple shadows on one element in webkit: -moz-box-shadow: inset 0 0 3px #999, 0 0 5px #fff; -webkit-box-shadow: inset 0 0 3px #999, 0 0 5px #fff; box-shadow: inset 0 0 3px #999, 0 0 5px #fff; it works fine in firefox but safari displays only the inset shadow. i tried to set both values separately. But safari takes just count of the last value: -webkit-box-shadow: inset 0 0 3px #999; -webkit-box-shadow: 0 5px #fff; is it possible to set more then one shadow on a single element in safari/webkit?

• How to do call function after client finishes download from tornado web server?

  - by Shabbyrobe

  I would like to be able to run some cleanup functions if and only if the client successfully completes the download of a file I'm serving using Tornado. I installed the firefox throttle tool and had it slow the connection down to dialup speed and installed this handler to generate a bunch of rubbish random text: class CrapHandler(BaseHandler): def get(self, token): crap = ''.join(random.choice(string.ascii_uppercase + string.digits) for x in range(100000)) self.write(crap) print "done" I get the following output from tornado immediately after making the request: done I 100524 19:45:45 web:772] 200 GET /123 (192.168.45.108) 195.10ms The client then plods along downloading for about 20 seconds. I expected that it would print "done" after the client was done. Also, if I do the following I get pretty much the same result: class CrapHandler(BaseHandler): @tornado.web.asynchronous def get(self, token): crap = ''.join(random.choice(string.ascii_uppercase + string.digits) for x in range(100000)) self.write(crap) self.finish() print "done" Am I missing something fundamental here? Can tornado even support what I'm trying to do? If not, is there an alternative that does?

• Programming language for web

  - by cable729

  I haven't programmed in a while, and have kind of lost interest, but I want to get back, and I've enjoyed C# the most, a lot more than objective-c and visual basic. So I want to make some games that me and my friends will be able to play next school year. So basically something you can play on the web. What programming languages deploy to the web? If c# is possible, and a mac with safari/firefox would be able to use it (I can't install plugins, and I don't want to get in trouble for making myself admin again) Flash, Java, etc. If java does, I'd like that most since it's most like c#. Then what libraries/engines would I use? I want to do 2d. And then what IDE would I use? Thanks in advance!

• Where does Visual Studio stores the default browser to use in debug?

  - by Fabian Vilers

  Hi all, I'm using Firefox as my default browser but when working in Visual Studio, I'd like to fire up IE when I go in debug. We all know that in MVC application, there's no way to choose the default browser unless you add a web form file, right click it, select browse with and then force a browser to be the default one. Great. My simple question is: where does VS stores the browser I just tell him to use (registry? project file? some xml config file?) I'm asking because VS loose this preference several times a month. I'm fed up with making the brower trick again and again. Thanks in advance, Fabian

• preg_match problem

  I'm trying to get some stuff from a string in php.

• valid json still fails on IE with jquery's ajax or getJSON callbacks

  - by lock

  everytime my page loads, im supposed to create a datatable (also a jquery plugin) but when im fetching the contents, using .ajax or .getJSON always goes straight ahead to the error function, without even telling me what went wrong inside the callback $.ajax({ cache: false, type: "POST", url: oSettings.sAjaxSource, data: {'newdate' : date}, contentType: "application/json; charset=utf-8", dataType: "json", success: function(json) { console.log('retrieving json data'); }, error: function() { console.log("An error has occurred. Please try again."); } }); that's the actual code with the callback stripped for security purposes... this works fine in firefox which actually executes what's on the callback function but IE simply fails and proceeds to writing my log i've read alot that the primary reason the JSON calls fails for IE is whenever there are trailing commas or simply malformed JS but i used JSONLint already and verified that my json object is a valid one :(

• jQuery using .animate() fails to do ANYTHING in IE8

  - by Cypher

  So, it's official: I hate Internet Explorer. Yes, all bloody versions of it. :-D So, I didn't think I was doing anything complicated here, but apparently I am. I have a bunch of list items in an unordered list styled for a navigation menu, and in Firefox, Chrome, Safari, and Opera, things work fine. What is supposed to happen is when you hover a navigational item, it should animate some growth and animate a background color change. Nothing happens in Internet Explorer 7/8. I think it's just tied to the animate function, since if I swap .animate with .css, it works. http://project-cypher.net/wtf/ Ideas?

• CKEditor adds html entities to inline CSS. Is the CSS still valid?

  - by Mihai Secasiu

  I have this piece of code: <table style="background-image: url(path/to_image.png)"> And when I load it in CKEditor it's transformed in: <table style="background-image: url(&quot;path/to_image.png&quot;)"> Is this still still valid CSS? Actually I'm not so interested if it's valid but if there would be any problems with any web browser or email client ( the editor is used for composing a html email ). Firefox and Thunderbird seem to be fine with it.

• http response to GET request - working in FF not Chromium

  - by Tyler

  For fun I'm trying to write a very simple server in C. When I send this response to Firefox it prints out the body "hello, world" but with Chromium it gives me a Error 100 (net::ERR_CONNECTION_CLOSED): Unknown error. This, I believe, is the relevant code: char *response = "HTTP/1.0 200 OK\r\nVary: Accept-Encoding, Accept-Language\r\nConnection: Close\r\nContent-Type: text/plain\r\nContent-Length:20\r\n\r\nhello, world"; if(send(new_fd, response, strlen(response), 0) == strlen(response)) { printf("sent\n"); }; close(new_fd); What am I missing? Thanks!

It's a paging mechanism so the hidden value was valid on the first page and I've been able to move forward to the next page. But since the values won't update properly it ends there. What do I need to do. Using firefox.
