• File.mkdir is not working and I can't understand why

  - by gotch4

  Hello, I've this brief snippet: String target = baseFolder.toString() + entryName; target = target.substring(0, target.length() - 1); File targetdir = new File(target); if (!targetdir.mkdirs()) { throw new Exception("Errore nell'estrazione del file zip"); } doesn't mattere if I leave the last char (that is usually a slash). It's done this way to work on both unix and windows. The path is actually obtained from the URI of the base folder. As you can see from baseFolder.toString() (baseFolder is of type URI and is correct). The base folder actually exists. I can't debug this because all I get is true or false from mkdir, no other explanations.The weird thing is that baseFolder is created as well with mkdir and in that case it works. Now I'm under windows. the value of target just before the creation of targetdir is "file:/C:/Users/dario/jCommesse/jCommesseDB" if I cut and paste it (without the last entry) in windows explore it works...

• Question on Win32 LogonUser API and the Logon Type

  - by Lalit_M

  We have developed a ASP.NET web application and has implemented a custom authentication solution using active directory as the credentials store. Our front end application uses a normal login form to capture the user name and password and leverages the Win32 LogonUser method to authenticate the user’s credentials. When we are calling the LogonUser method, we are using the LOGON32_LOGON_NETWORK as the logon type. The issue we have found is that user profile folders are being created under the C:\Users folder of the web server. The folder seems to be created when a new user who has never logged on before is logging in for the first time. As the number of new users logging into the application grows, disk space is shrinking due to the large number of new user folders getting created. Has anyone seen this behavior with the Win32 LogonUser method? Does anyone know how to disable this behavior?

• C# threading a FolderBrowserDialog

  - by Marthin

  Hi, Im trying to use the FolderBrowserDialog to select a folder in C#. At first I got a Thread exception, so I googled what was wrong and fixed that but now im stuck at a nother problem. I whant to know when a folder has been selected. This is what i'v got right now. private void btnWorkingFolder_Click(object sender, EventArgs e) { var t = new Thread(SelectFolder); t.IsBackground = true; t.SetApartmentState(ApartmentState.STA); t.Start(); } private void SelectFolder() { FolderBrowserDialog dialog = new FolderBrowserDialog(); if (dialog.ShowDialog() == DialogResult.OK) { txtWorkFolder.Text = dialog.SelectedPath; } } } The problem here is that i cant Set the Text for txtWorkingFolder since im not in the same thread. I dont want to change the thread for txtWorkingFolder, so my question is this, how do I change it's value from the new thread once the DialogResult.OK has been set? Thx for any help! /Marthin

• How to deploy RESTful Web Service onto IIS

  - by Chris Lee

  Hi all, I'm new to .Net and IIS. I've created a simple RESTful Web Service in VS2008 and .net 3.5 framework using WCF. I've tested it well with F5 debugging in VS(seems it is auto deployed on Windows Service). Now I want to deploy it on my IIS server so that I can use it remotely. But I cannot find any guide for this. I manually deployed my service folder just as an ASP.net site. But seems it does not work(keep showing 401 error). Can anyone tell me how to deploy it to IIS? It contains a simple GET method and I hope it can be accessed by anomynous clients (because the host IP is 192.168..). I have a web.config file, a .dll and .pdb under /bin folder, a Global.asax and .svc file for my service. The IIS server is on the same machine. Thanks a million.

• Executing php with crontab

  - by Stefan Konno

  Hi everyone. I'm trying to run a php-script on a scheduled basis. So I'd thought crontab was a good idea. The server I'm using is on Linux which I'm not that familiar with. So the problem I'm having is, I don't know how make the script executable from php. I need to reference the script, or put it into a folder that can run php from the command line. So I don't know what path to give my crontab, for example: 5 * * * * var/www/some/path/script.php I found some vague information about this php executable being found in /usr/bin/php But I can't find any php file in there, maybe I don't have it installed? My php5 and apache installation is in: /etc/php5 So my question becomes, is there anyway to execute a php-script with crontab in any other folder, or do I just lack the php executable in usr/bin/php?

• Trying to debug a plugin in tuxguitar, need help building the project in Eclipse.

  - by Shawn Simon

  I am not too familiar with java / eclipse but I am trying to debug a plugin in TuxGuitar. The plugin is the gtp plugin which allows reading of guitar pro files. I have imported the main project, TuxGuitar, and the TuxGuitar-gtp plugin. I have all build dependencies configured and the project builds. However, when I debug the app, the plugin is not available. The documentation says plugins are loaded from the share/plugins folder and they are jar files. I tried exporting the gtp plugin as a jar into the share/plugins folder, but it still does not load when I debug. Is there some sort of configuration I need to do in Eclipse? Thanks!

• Localization with separate Language folders within Views

  - by Adrian

  I'm trying to have specific folders for each language in Views. (I know this isn't the best way of doing it but it has to be this way for now) e.g. /Views/EN/User/Edit.aspx /Views/US/User/Edit.aspx These would both use the same controller and model but have different Views for each language. In my Global.asax.cs I have routes.MapRoute( "Default", // Route name "{language}/{controller}/{action}/{id}", // URL with parameters new { language = "en", controller = "Logon", action = "Index", id = UrlParameter.Optional }, // Parameter defaults new { language = @"en|us" } // validation ); This works ok but always points to the same View. If I put the path to the Lanagugage folder it works return View("~/Views/EN/User/Edit.aspx"); but clearly this isn't a very nice way to do it. Is there anyway to get MVC to look in the correct language folder? Thanks and again I know this isn't the best way of doing Localization but I can't use resource files.

• Replacing IFrame with div

  - by Roland

  I have a IFrame where I load in a custom search, and display the results within the iframe. The search results I obtain by calling an external url, that returns a value. I need to implement the same thing for a mobi site that works on mobile devices, and thus I need to replace the IFrame with something else. Will this be possible using a div tag, since most mobile devices do not support frames. And no javascript may be used. Any advice will be appreciated.

• What is your most productive shortcut with Vim?

  - by Olivier Pons

  I've heard a lot about Vim, both pros and cons. It really seems you should be (as a developer) faster with Vim than with any other editor. I'm using Vim to do some basic stuff and I'm at best 10 times less productive with Vim. The only two things you should care about when you talk about speed (you may not care enough about them, but you should) are: Using alternatively left and right hands is the fastest way to use the keyboard. Never touching the mouse is the second way to be as fast as possible. It takes ages for you to move your hand, grab the mouse, move it, and bring it back to the keyboard (and you often have to look at the keyboard to be sure you returned your hand properly to the right place) Here are two examples demonstrating why I'm far less productive with Vim. Copy/Cut & paste. I do it all the time. With all the classical editors you press Shift with the left hand, and you move the cursor with your right hand to select text. Then Ctrl+C copies, you move the cursor and Ctrl+V pastes. With Vim it's horrible: yy to copy one line (you almost never want the whole line!) [number xx]yy to copy xx lines into the buffer. But you never know exactly if you've selected what you wanted. I often have to do [number xx]dd then u to undo! Another example? Search & replace. In PSPad: Ctrl+f then type what you want you search for, then press Enter. In Vim: /, then type what you want to search for, then if there are some special characters put \ before each special character, then press Enter. And everything with Vim is like that: it seems I don't know how to handle it the right way. NB : I've already read the Vim cheat sheet :) My question is: What is the way you use Vim that makes you more productive than with a classical editor?

• Is SEO knowledge important for web developers?

  - by splattne

  Looking for some SEO (Search engine optimization) questions on Stackoverflow, I saw ambivalent reactions to these questions. Some were closed as "not programming related" or were downvoted, others were answered and got upvoted. It seems that many developers think SEO was something "dirty" or belonged in the realm of spam. IMHO designing for search engines and practising SEO techniques adds important value to the final product like, for example, a good user interface. Should SEO really be left to specialized non-programmers? Shouldn't web developers have profound SEO knowledge? Or is it okay to apply SEO as a post-development process?

• problems with unpickling a 80 megabyte file in python

  - by tipu

  I am using the pickle module to read and write large amounts of data to a file. After writing to the file a 80 megabyte pickled file, I load it in a SocketServer using class MyTCPHandler(SocketServer.BaseRequestHandler): def handle(self): print("in handle") words_file_handler = open('/home/tipu/Dropbox/dev/workspace/search/words.db', 'rb') words = pickle.load(words_file_handler) tweets = shelve.open('/home/tipu/Dropbox/dev/workspace/search/tweets.db', 'r'); results_per_page = 25 query_details = self.request.recv(1024).strip() query_details = eval(query_details) query = query_details["query"] page = int(query_details["page"]) - 1 return_ = [] booleanquery = BooleanQuery(MyTCPHandler.words) if query.find("(") > -1: result = booleanquery.processAdvancedQuery(query) else: result = booleanquery.processQuery(query) result = list(result) i = 0 for tweet_id in result and i < 25: #return_.append(MyTCPHandler.tweets[str(tweet_id)]) return_.append(tweet_id) i += 1 self.request.send(str(return_)) However the file never seems to load after the pickle.load line and it eventually halts the connection attempt. Is there anything I can do to speed this up?

• NTFS-compressing Virtual PC disks (on host and/or guest)

  - by nlawalker

  I'm hoping someone here can answer these definitively: Does putting a VHD file in an NTFS-compressed folder on the host improve performance of the virtual machine, diminish performance, or neither? What about using NTFS compression within the guest? Does using compresssion on either the host or the guest lead to any problems like read or write errors? If I were to put a VHD in a compressed folder on the host, would I benefit from compacting it? I've seen references to using NTFS compression on quite a few VPC "tips and tricks" blog posts, and it seems like half of them say to never do it and the other half say that not only does it save disk space but it actually can improve performance if you have a fast CPU and your primary performance bottleneck is the disk.

• Exporting query results to a file on the fly

  - by ercan

  Hi all, I need to export the results of a query to a csv file in an FTP folder. Is it possible to achieve this within a stored procedure? If yes, comes yet another constraint: can I achieve this without sysadmin privileges, aka without using xp_cmdshell + BCP utility? If no to 2., does the caller have to have sysadmin privileges or would it suffice if the SP owner has sysadmin privileges? Here are some more details to the problem: The SP must export and transfer the file on the fly and raise error if something went wrong. The caller must get a response immediately, i.e. in case of no error, he can assume that the results are successfully transferred to the folder. Therefore, a DTS/SSIS job that runs every N minutes is not an option. I know the problem smells like I will have to do this at application level, but I would be more than happy if all those stuff could be done from T-SQL.

• C# "Could not find a part of the path" - Creating Local File

  - by Pyronaut

  I am trying to write to a folder that is located on my C:\ drive. I keep getting the error of : Could not find a part of the path .. etc My filepath looks basically like this : C:\WebRoot\ManagedFiles\folder\thumbs\5c27a312-343e-4bdf-b294-0d599330c42d\Image\lighthouse.jpg And I am writing to it like so : using (MemoryStream memoryStream = new MemoryStream()) { thumbImage.Save(memoryStream, ImageFormat.Jpeg); using (FileStream diskCacheStream = new FileStream(cachePath, FileMode.CreateNew)) { memoryStream.WriteTo(diskCacheStream); } memoryStream.WriteTo(context.Response.OutputStream); } Don't worry too much about the memory stream. It is just outputting it (After I save it). Since I am creating a file, I am a bit perplexed as to why it cannot find the file (Shouldn't it just write to where I tell it to, regardless?). The strange thing is, It has no issue when I'm testing it above using File.Exists. Obviously that is returning false, But it means that atleast my Filepath is semi legit. Any help is much appreciated.

• Git remove directory

  - by hrickards

  I've got a repository on GitHub (http://github.com/hrickards/PHP-Crypto) for a little project me and a couple of others are working on. My development environment is Aptana Studio, and I use the EGit plugin as Aptana is basically Eclipse underneath. Today the designer sent the HTML and CSS for the website with the images in a folder named img. Previously the images were in a folder called images. Thinking nothing of it and being too lazy to update the CSS and HTML, I simply kept the images in the img directory and commited to Git. However, the GitHub web interface shows both the img and images directories, with the images directory being empty. I've tried deleting the images directory with git rm -r images and git rm images, and even mkdir images; git add images; git rm -r images but whatever I try I get the same result: fatal: pathspec 'images' did not match any files. Has anyone got any advice on how to remove images, or am I misunderstanding Git or something?

• ASP.net Text Box Enter button pressed hell

  - by Morgeh

  Basically I have an asp.net website with login and search pages. Currently, I have no idea why, when ever a user hits enter in either of the login text boxes (user name/password) or in the Seach text box, the website is redirected to the default page. I have no idea why this is happening, I've tried setting defaultButton on both the panel containing the search and the login panel but that doesnt seem to work. I've also tried catching the key press event with javascript which isnt working either. I have no idea what event is being fired and why, or why it seems to override everything I try to do. Anyone seen anything like this before?

• Dynamic "OR" conditions in Rails 3

  - by Ryan Foster

  I am working on a carpool application where people can search for lifts. They should be able to select the city from which they would liked to be picked up and choose a radius which will then add the cities in range to the query. However the way it is so far is that i can only chain a bunch of "AND" conditions together where it would be right to say "WHERE start_city = city_from OR start_city = a_city_in_range OR start_city = another_city_in_range" Does anyone know how to achive this? Thanks very much in advance. class Search < ActiveRecord::Base def find_lifts scope = Lift.where('city_from_id = ?', self.city_from) #returns id of cities which are in range of given radius @cities_in_range_from = City.location_ids_in_range(self.city_from, self.radius_from) #adds where condition based on cities in range for city in @cities_in_range_from scope = scope.where('city_from_id = ?', city) #something like scope.or('city_from_id = ?', city) would be nice.. end end

• Is it possible to define a virtual directory in IIS and make the files relative to the physical dire

  - by Mikey John

  Is it possible to define a virtual directory in IIS and somehow make the files in that directory relative to the physical directory and not to the virtual directory ? For instance on my server I have the following folders: D:\WebSite\Css\myTheme.css, D:\WebSite\Images\image1.jpg I created a virtual directory on IIS resources.mysite: Inside my website I reference the sheet like this resources.mysite/myTheme.css But inside myTheme.css I reference pictures from ../Images/images1.jpg. So the problem is that image1.jpg is not found because it is relative to the physical folder and not the virtual folder on IIS. Can I solve this problem without modifying the style sheet ?

• Autocomplete server-side implementation

  - by toluju

  What is a fast and efficient way to implement the server-side component for an autocomplete feature in an html input box? I am writing a service to autocomplete user queries in our web interface's main search box, and the completions are displayed in an ajax-powered dropdown. The data we are running queries against is simply a large table of concepts our system knows about, which matches roughly with the set of wikipedia page titles. For this service obviously speed is of utmost importance, as responsiveness of the web page is important to the user experience. The current implementation simply loads all concepts into memory in a sorted set, and performs a simple log(n) lookup on a user keystroke. The tailset is then used to provide additional matches beyond the closest match. The problem with this solution is that it does not scale. It currently is running up against the VM heap space limit (I've set -Xmx2g, which is about the most we can push on our 32 bit machines), and this prevents us from expanding our concept table or adding more functionality. Switching to 64-bit VMs on machines with more memory isn't an immediate option. I've been hesitant to start working on a disk-based solution as I am concerned that disk seek time will kill performance. Are there possible solutions that will let me scale better, either entirely in memory or with some fast disk-backed implementations? Edits: @Gandalf: For our use case it is important the the autocompletion is comprehensive and isn't just extra help for the user. As for what we are completing, it is a list of concept-type pairs. For example, possible entries are [("Microsoft", "Software Company"), ("Jeff Atwood", "Programmer"), ("StackOverflow.com", "Website")]. We are using Lucene for the full search once a user selects an item from the autocomplete list, but I am not yet sure Lucene would work well for the autocomplete itself. @Glen: No databases are being used here. When I'm talking about a table I just mean the structured representation of my data. @Jason Day: My original implementation to this problem was to use a Trie, but the memory bloat with that was actually worse than the sorted set due to needing a large number of object references. I'll read on the ternary search trees to see if it could be of use.
