• Which Perl moudle can handle variety of date formats with unicode characters ?

  - by ram

  My requirement is parsing xml files which contains wide varieties of timestamps based on the locales at which they are written. They may contain Unicode characters in case of Chinese or Korean locales. I have to parse these timestamps and put then in a standard format something like 2009-11-26 12:40:54 to put them in a oracle database. Sometimes I may not even know the locale and yet I have to parse the timestamps. I am looking for a module that automatically detects the timestamp format (including unicode characters for am and pm in their local language) and converts in to epoch time so that I can convert it back to what ever way I like to. I have gone through similar questions in this forum. Few suggested DateFormat module, and Date::Parse module. The perl distribution I am using is 5.10 so Date::Manip doesn't come as a core module. As I am supposed to use just the basic core modules and few CPAN modules(on request I cannot ask for all), I request you to kindly suggest me a good module that suffices all my requirements. Thanks in advance

• What is a mantainable way of saving "star rating" in a database?

  - by Montecristo

  I'll use the jQuery plugin for presenting the user with a nice interface The request is to display 5 stars, up to a total score of 10 (2 points per star). By now I thought about using 7/10 as a format for that value, but what if at some point in the future I'll receive a request like We would like to give users more choice, let's increase the total score to 20 (so that each star contributes with a maximum of 4 points) I'll end up with a table with mixed values for the "star rating" column: some will be like 7/10 while others will be like 14/20. Is it ok for you to have this difference in the database and deal with it in the logic layer to have it consistent? Or is preferred another way so that querying the table will not result in inconsistent results outside the application? Maybe floating point values could help me, is it better to store that value as a number less than or equal to one? So in each of the two examples the resulting value stored in the database would be 0,7, as a number, not a varchar, which can be queried also outside the application. What do you think?

• GUnload is null or undefined using Directions Service

  - by user1677756

  I'm getting an error using Google Maps API V3 that I don't understand. My initial map displays just fine, but when I try to get directions, I get the following two errors: Error: The value of the property 'GUnload' is null or undefined, not a Function object Error: Unable to get value of the property 'setDirections': object is null or undefined I'm not using GUnload anywhere, so I don't understand why I'm getting that error. As far as the second error is concerned, it's as if something is wrong with the Directions service. Here is my code: var directionsDisplay; var directionsService = new google.maps.DirectionsService(); var map; function initialize(address) { directionsDisplay = new google.maps.DirectionsRenderer(); var geocoder = new google.maps.Geocoder(); var latlng = new google.maps.LatLng(42.733963, -84.565501); var mapOptions = { center: latlng, zoom: 15, mapTypeId: google.maps.MapTypeId.ROADMAP }; map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions); geocoder.geocode({ 'address': address }, function (results, status) { if (status == google.maps.GeocoderStatus.OK) { map.setCenter(results[0].geometry.location); var marker = new google.maps.Marker({ map: map, position: results[0].geometry.location }); } else { alert("Geocode was not successful for the following reason: " + status); } }); directionsDisplay.setMap(map); } function getDirections(start, end) { var request = { origin:start, destination:end, travelMode: google.maps.TravelMode.DRIVING }; directionsService.route(request, function(result, status) { if (status == google.maps.DirectionsStatus.OK) { directionsDisplay.setDirections(result); } else { alert("Directions cannot be displayed for the following reason: " + status); } }); } I'm not very savvy with javascript, so I could have made some sort of error there. I appreciate any help I can get.

• Signed_request lost in ASP.NET session, confusing my website

  - by Csabi

  I have an ASP.NET MVC 3 website which is available both from a specific public url, and I'm also making be available as a Facebook App. Inside my website logic, in some places I have to determine whether the current request is from the Facebook-app, or from the public website, because I want to display content based on this environment. So, for eg. if the user is using my site as a facebook-app, then I want to display a picture, and if the user is using my site normally, then I don't wanna display a picture. To determine whether I'm from a Facebook app, I check the "signed_request" in the HttpContext.Request, and store it in the HttpSession to be available for my other actions, not just for that action (url) which is defined for my Facebook app. So when a child-action is executed, I can determine based on the Session, that the website is used as a FB-app or not. The problem happens, when the Session times out, because then althought the logic is still running inside Facebook, my logic thinks it's not inside Facebook. Any advice?

• How to configure an index.htm file in IIS?

  - by salvationishere

  I am running IIS 6.0 on an XP OS using VS 2008 and SQL Server 2008 (Full install). I developed two web apps. Both of these I can run from IIS by setting them to the default website. However, now I tried adding an index.htm file. Real simple; all it has is two hyperlinks to these web apps. But now only the first web app works. The first web app is pure VS. The second web app modifies an Adventureworks database table. But now when I click the hyperlink for the second web app, it gives me the error below. However this error doesn't make sense to me cause I have the two web apps configured as two virtual directories beneath C:\inetpub\ and the index.htm file is also beneath C:\inetpub. And the default website is set to home directory C:\inetpub\ with Document index.htm on top. Also, why does the first web app work and not the second now? Server Error in '/AddFileToSQL' Application. The path '/AddFileToSQL/App_GlobalResources/' maps to a directory outside this application, which is not supported. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Web.HttpException: The path '/AddFileToSQL/App_GlobalResources/' maps to a directory outside this application, which is not supported.

• django multiprocess problem

  - by iKiR

  I have django application, running under lighttpd via fastcgi. FCGI running script looks like: python manage.py runfcgi socket=<path>/main.socket method=prefork \ pidfile=<path>/server.pid \ minspare=5 maxspare=10 maxchildren=10 maxrequests=500 \ I use SQLite. So I have 10 proccess, which all work with the same DB. Next I have 2 views: def view1(request) ... obj = MyModel.objects.get_or_create(id=1) obj.param1 = <some value> obj.save () def view2(request) ... obj = MyModel.objects.get_or_create(id=1) obj.param2 = <some value> obj.save () And If this views are executed in two different threads sometimes I get MyModel instance in DB with id=1 and updated either param1 or param2 (BUT not both) - it depends on which process was the first. (of course in real life id changes, but sometimes 2 processes execute these two views with same id) The question is: What should I do to get instance with updated param1 and param2? I need something for merging changes in different processes. One decision is create interprocess lock object but in this case I will get sequence executing views and they will not be able to be executed simultaneously, so I ask help

• how to resize image

  - by saadan

  I am a little forgetful have made it many times and can not find the code from the last time I made it how do I get it to resize more than one picture i do like this Guid imageName; imageName = Guid.NewGuid(); string storePath = Server.MapPath("~") + "/MultipleUpload"; if (!Directory.Exists(storePath)) Directory.CreateDirectory(storePath); hif.PostedFile.SaveAs(storePath + "/" + Path.GetFileName(hif.PostedFile.FileName)); string tempPath = "Gallery"; string imgPath = "Galleryt"; string savePath = Path.Combine(Request.PhysicalApplicationPath, tempPath); string TempImagesPath = Path.Combine(savePath, imageName + hif.PostedFile.FileName); string imgSavePath = Path.Combine(Request.PhysicalApplicationPath, imgPath); string ProductImageNormal = Path.Combine(imgSavePath, "t__" + imageName + hif.PostedFile.FileName); string extension = Path.GetExtension(hif.PostedFile.FileName); switch (extension.ToLower()) { case ".png": goto case "Upload"; case ".gif": goto case "Upload"; case ".jpg": goto case "Upload"; case "Upload": hif.PostedFile.SaveAs(TempImagesPath); ImageTools.GenerateThumbnail(TempImagesPath, ProductImageNormal, 250, 350, true, "heigh"); Label1.Text = ""; break; }

• 3 questions about JSON-P format.

  - by Tristan

  Hi, I have to write a script which will be hosted on differents domains. This script has to get information from my server. So, stackoverflow's user told me that i have to use JSON-P format, which, after research, is what i'm going to do. (the data provided in JSON-P is for displaying some information hosted on my server on other website) How do I output JSON-P from my server ? Is it the same as the json_encode function from PHP How do i design the tree pattern for the output JSON-P (you know, like : ({"name" : "foo", "id" : "xxxxx", "blog" : "http://xxxxxx.com"}); can I steal this from my XML output ? (http://bit.ly/9kzBDP) Each time a visitor browse a website on which my widget is it'll make a request on my server, requesting the JSON-P data to display on the client side. It'll increase dramatically the CPU load (1 visitor on the website who will have the script = 1 SQL request on my server to output data), so is there any way to 'caching' the JSON-P information output to refresh it only one or twice a day and stores it into a 'file' (in which extension?). BUT on the other hand i would say that requesting the JSON-P data directly (without caching it) is a plus, because, websites which will integrates the script only want to display THEIR information and not the whole data. So, making a script with something like that: jQuery.getJSON("http://www.something.com/json-p/outpout?filter=5&callback=?", function(data) { ................); }); Where filter= the information the website wants to display What do you think ? Thank you very much ;)

• Flash browser game - HTTP + PHP vs Socket + Something else

  - by Maurycy Zarzycki

  I am developing a non-real time browser RPG game (think Kingdom of Loathing) which would be played from within a Flash app. At first I just wanted to make the communication with server using simply URLLoader to tell PHP what I am doing, and using $_SESSION to store data needed in-between request. I wonder if it wouldn't be better to base it on a socket connection, an app residing on a server written in Java or Python. The problem is I have never ever written such an app so I have no idea how much I'd have to "shift" my thoughts from simple responding do request (like PHP) to continuously working application. I won't hide I am also concerned about the memory and CPU usage of such Server app, when for example there would be hundreds of users connected. I've done some research. I have tried to do some research, but thanks to my nil knowledge on the sockets subject I haven't found anything helpful. So, considering the fact I don't need real time data exchange, will it be wise to develop the server side part as socket server, not in plain ol' PHP?

• Adding property:value pairs from GooglemapsAPI to an existing json/javascript object

  - by Rockinelle

  I am trying to create a script that finds the closest store/location to a customer using googlemapsAPI. So I've got a json object which is a collection of store objects. Using Jquery's .each to iterate through that object, I am grabbing the driving time from the customer to each store. If it finds the directions, It copies the duration of the drive which is an object with the time in seconds and a human readable value. That appears to work, however when I try to sort through all of those store objects with the drivetime added, I cannot read the object copied from google. If I console.log the whole object, 'closest_store', It shows the values I'm looking for. When I try to read the values directly via closest_store.driveTime, Firebug is outputting undefined in the console. What am I missing here? $.getJSON('<?php echo Url::base() ?>oldservices/get_locations', {}, function(data){ $.each(data, function(index, value) { var end = data[index].address; var request = { origin: start, destination: end, travelMode: google.maps.DirectionsTravelMode.DRIVING }; directionsService.route(request, function(response, status) { //console.log(response); if (status == google.maps.DirectionsStatus.OK) { value.driveTime = response.trips[0].routes[0].duration.value; //console.log(response.trips[0].routes[0].duration.value); }; }); }); var closest_store; $.each(data, function(index, current_store) { if (index == 0) { closest_store = current_store; } else if (current_store.driveTime.value < closest_store.driveTime.value) { closest_store = value }; console.log(current_store.driveTime); } ) });

• GET is not working for firstResource Rest example

  - by Anandan

  Hi, I am newbie to rest. I am using the following code example to understand the RESTlet. http://www.restlet.org/documentation/1.1/firstResource I am using RESTClient addon to firefox for testing. When i do GET on http://localhost/rest, i get a response "ok". But when i do GET on http://localhost/items, I get an error "404 Not found" Here's the sample code: public synchronized Restlet createRoot() { Router router = new Router(getContext()); router.attach("/items", ItemsResource.class); router.attach("/items/{itemName}", ItemResource.class); Restlet restlet = new Restlet() { @Override public void handle(Request request, Response response) { StringBuilder stringBuilder = new StringBuilder(); stringBuilder.append("ok"); response.setEntity(new StringRepresentation(stringBuilder .toString(), MediaType.TEXT_HTML)); } }; router.attach("/rest", restlet); return router; } ItemResource is same as provided in the link. and I use tomcat to run the servlet. Why am I getting the "Not found" error? Am i missing something here? Thanks & Regards, Anandan

• Downloading From Google Docs

  - by jeremynealbrown

  Hello, I am using the gdata-java-client Version 2 with for and Android app that allows users to download documents from their Google Docs account. Currently I am able to authenticate, request and display a list of all the user's documents. From here I would like to open each type of document in a specific Activity. If it's a spreadsheet or a csv file, open it in one activity and if it is a text document open it in another activity. This is where things are getting hazy. First I need to determine what type of document the user selected in order download the file in the appropriate format by appending exporFormat=(csv,xls,doc,txt) to the query string. I don't see any indication in the original list of documents as to what kind of file the each entry is. Secondly as a test I can just append a raw string to the end of the query string. As an example, a query might look like this: https://spreadsheets.google.com/feeds/download/spreadsheets/Export?key=0AsE_6_YIr797dHBTUWlHMUFXeTV4ZzJlUGxWRnJXanc&exportFormat=xls Notice that at the end of the string is the hardcoded export format. This query returns a HTTPResponse with a 200 OK message. However if I look at the response.content or use response.parseAsString I see what appears to be a Google Docs home page has html text. I don't get this result when I try to download a text document. When I request a text document the response.content is the body of the text file. If I copy and paste this uri into a browser I get the requested file as a download. To summarize, this question is two-fold: 1. How do I determine the type( plain text, .doc, .csv, .xls ) of a document from the initial list of user documents. 2. How do I download the actual .csv or spreadsheet files? Thanks in advance.

• How to use Node.js to build pages that are a mix between static and dynamic content?

  - by edt

  All pages on my 5 page site should be output using a Node.js server. Most of the page content is static. At the bottom of each page, there is a bit of dynamic content. My node.js code currently looks like: var http = require('http'); http.createServer(function (request, response) { console.log('request starting...'); response.writeHead(200, { 'Content-Type': 'text/html' }); var html = '<!DOCTYPE html><html><head><title>My Title</title></head><body>'; html += 'Some more static content'; html += 'Some more static content'; html += 'Some more static content'; html += 'Some dynamic content'; html += '</body></html>'; response.end(html, 'utf-8'); }).listen(38316); I'm sure there are numerous things wrong about this example. Please enlighten me! For example: How can I add static content to the page without storing it in a string as a variable value with += numerous times? What is the best practices way to build a small site in Node.js where all pages are a mix between static and dynamic content?

• Mysterious HttpSession and session-config dependency

  - by OneMoreVladimir

  Good day. I'm developing a Java web app with Servlets\JSP using Tomcat 7.0. During request from client I put and object into the session and use forward. After the forward processing the same request the object can be retreived if the secure parameter is false otherwise it is not stored in session. <session-config> <session-timeout>15</session-timeout> <cookie-config> <http-only>true</http-only> <secure>true</secure> </cookie-config> <tracking-mode>COOKIE</tracking-mode> </session-config> I've figured out that "...cookies can be created with the 'secure' flag, which ensures that the browser will never transmit the specified cookie over non-SSL...". I've configured Tomcat to use SSL, but that haven't helped. Changing the tracking mode to SSL haven't helped as well. How do session-config and HttpSession object correlate in this case? What could be the problem?

• VB app to web service

  - by brandon

  I know very little about web service but I assumed it would be the solution I was looking for. Basically I made an application in VB that I want to be ubiquitous for a lack of a better word. I need it to receive requests from multiple users and respond all at once. I was told "technically if you write a webservice you can provide as many results back to users as are connected." Maybe there is another solution for me that will give me the results I want. Here is an example of what I'm trying to do. Lets say I make an application in VB that does math. I now make a website. My website allows for a person to input 1 + 1 they click submit and my website then connects to my VB application running on my server listening for a request. It accepts the request from my website, and then it solves the math problem and returns the answer back to the website "1 + 1 = 2" That is only an example of the type of thing I need. My problem is that I can't have multiple people visiting my website all connecting to that same application running on my server so somehow I need the application to be where it can be accessed by multiple users. I was told a web service would be the answer but if there is another solution I'd like to know. If the only solution is a web service, then how can I manage to either convert the VB app to a web service? Can I have to convert the app to asp.net or some other language? Is there an easier option?

• Dynamic control click event not firing properly

  - by Wil

  I'm creating a next/previous function for my repeater using pageddatasource. I added the link button control dynamically in my oninit using the following code. LinkButton lnkNext = new LinkButton(); lnkNext.Text = "Next"; lnkNext.Click += new EventHandler(NextPage); if (currentPage != objPagedDataSource.PageCount) { pnlMain.Controls.Add(lnkNext); } So in my initial page_load, the next link comes up fine. There are 5 pages in my objPagedDataSource. currentPage variable is 1. The "NextPage" event handler looks like this public void NextPage(object sender, EventArgs e) { if (HttpContext.Current.Request.Cookies["PageNum"] == null) { HttpCookie cookie = new HttpCookie("PageNum"); cookie.Value = "1"; } else { HttpCookie cookie = HttpContext.Current.Request.Cookies["PageNum"]; cookie.Value = (Convert.ToInt32(cookie.Value) + 1).ToString(); } this.BindRepeater(); } So I am incrementing the cookie I am using to track the page number and then rebinding the repeater. Here is the main issue. The first time I click Next, it works, it goes to Page 2 without any problems. When on Page 2, I click Next, it goes back to Page 1. Seems like the Next event is not wiring up properly. Not sure why, any ideas?

• .NET - Unable to get values from Value property of HtmlInputHidden

  - by user245123

  I have a custom control that inherits from .NET's CompositeControl class. This control overrides the CreateChildControls in order to build its child controls dynamically. I need the page to post back after a couple different javascript events occur on the client side. In order to accomplish this, I create two hidden controls on the page so I can set their values with javascript, submit the page, and read the values out on server side. Here's is the code I use to create these two hiddens: Protected Overrides Sub CreateChildControls() hdEventName = New HiddenField() Controls.Add(hdEventName) hdEventName.ID = "hdEventName" hdEventArgs = New HiddenField() Controls.Add(hdEventArgs) hdEventArgs.ID = "hdEventValue" ' other controls ' ... End Sub When a javascript event occurs I set the value attribute of the two hiddens and submit the page, like so: hdEventName.value = 'EventName'; hdEventArgs.value = 'arg1,arg2'; document.forms[0].submit(); In the OnLoad method of my control, I attempt to check the Value property of the hdEventName and hdEventArgs controls, but it is always empty. However, Page.Request.Form(hdEventName.UniqueID) and Page.Request.Form(hdEventArgs.UniqueID) return correct values. The actual HTML in the markup also shows correct values after the page posts back. Why is the Value property of the HtmlInputHiddens disconnected from the actual value that appears on the client?

• AJAX/JSONP Question. Access id denied using IE while requesting corss domain.

  - by Sisir

  Ok, Here we go. I have already searched the Stack for the answer i have found some useful info but i want to clear up some more things. I also search the net for the answer but no real help. I have worked with some api (yelp, ouside.in). In yelp i use to inject the script to head with the url request to the api with a callback funcion. I worked fine in all browsers. But while using outside.in api when i call the url the callback in not working. In yelp they have a url field can be used like that callback=callbackfuncion so the callback will automatically called. But in outside.in there is not such field available. Is there are any standard command for callback function which will work regardless of any server/api? I also tried a standard ajax request using jQuery $.ajax() function. It worked for my local pc for both IE and other browser but did not working in IE showing the error: access denied, other borwser seems ok. Firebug in my FF also don't notice any errors. Outside.in has an javascript example but it is too hard to me to understand github.com/outsidein/api-examples/tree/master/javascript/browser/ site i am working: http://citystir.com yelp: yelp.com outside.in: outside.in Techniqual info: i am using: wampserver in local, wordpress for hosting, Godaddy, apache for remote with linux. Codes: Using Jquery $.ajax url is like: "http://hyperlocal-api.outside.in/v1.1/states/Illinois/cities/chicago/stories?dev_key="+key+"&sig="+signeture+"&limit=3 function makeOutsideRequest(url){ $.ajax({ url: url, dataType: 'json', type: 'GET', success: function (data, status, xhr) { if (data == null) { alert("An error occurred connecting to " + url + ". Please ensure that the server is running and configured to allow cross-origin requests."); }else{ printHomeNews(data); } }, error: function (xhr, status, error) { alert("An error occurred - check the server log for a stack trace."); } }); } Thanks!

• File upload issue

  - by Varun

  I am working on a PHP based, ticket management system. While creating a ticket, one can upload an attachment. I want to put a limit (say 10 MB) per file upload. To implement this I plan the following- 1. In php.ini set post_max_size = 10M 2.In PHP script which receives the POST- Since the file is larger than post_max_size, $_FILES[] will be empty. But I can still check the content-length header and discard the upload, if size more than 10M. While testing this I tried uploading a file of 1 GB and analysed the http traffic and this is what I found. - the entire 1 GB data is first uploaded to a to the server temporarily and discarded once the http request completes. Though I couldn't exactly find out where the file was getting saved(as it was not there in the temporary directory in the server.), but my http traffic analyzer showed that the browser did send 1 GB data to the server. - the PHP script execution started only after completion of the http request(i.e after uploading the entire 1 GB) Now I have 2 concerns: a) People may exploit my server bandwidth by trying to upload large file, which I will have to discard anyways. b) Even worse, if someone starts uploading a huge file (say 100 GB), entire 100 GB data is first uploaded to the server temporarily, that means for that period, it will consume that much of memory on my server. What's the common solution for this. Am I missing something here?
