  • C# remove redundant paths from a list

    - by andrew
    Say I have this list List<string> sampleList = new List<string> { "C:\\Folder1", "D:\\Folder2", "C:\\Folder1\\Folder3", "C:\\Folder111\\Folder4" }; I'd like to remove the paths that are contained in other folders, for example we have C:\Folder1 and C:\Folder1\Folder3 the second entry should go away because C:\Folder1 contains C:\Folder1\Folder3 is there something that does that in the .net framework or do i have to write the algo myself?

  • Stand-alone Java code formatter/beautifier/pretty printer?

    - by Greg Mattes
    I'm interested in learning about the available choices of high-quality, stand-alone source code formatters for Java. The formatter must be stand-alone, that is, it must support a "batch" mode that is decoupled from any particular development environment. Ideally it should be independent of any particular operating system as well. So, a built-in formatter for the IDE du jour is of little interest here (unless that IDE supports batch mode formatter invocation, perhaps from the command line). A formatter written in closed-source C/C++ that only runs on, say, Windows is not ideal, but is somewhat interesting. To be clear, a "formatter" (or "beautifier") is not the same as a "style checker." A formatter accepts source code as input, applies styling rules, and produces styled source code that is semantically equivalent to the original source code. A style checker also applies styling rules, but it simply reports rule violations without producing modified source code as output. So the picture looks like this: Formatter (produces modified source code that conforms to styling rules) Read Source Code → Apply Styling Rules → Write Styled Source Code Style Checker (does not produce modified source code) Read Source Code → Apply Styling Rules → Write Rule Violations Further Clarifications Solutions must be highly configurable. I want to be able to specify my own style, not simply select from a canned list. Also, I'm not looking for a general purpose pretty-printer written in Java that can pretty-print many things. I want to style Java code. I'm also not necessarily interested in a grand-unified formatter for many languages. I suppose it might be nice for a solution to have support for languages other than Java, but that is not a requirement. Furthermore, tools that only perform code highlighting are right out. I'm also not interested in a web service. I want a tool that I can run locally. Finally, solutions need not be restricted to open source, public domain, shareware, free software, commercial, or anything else. All forms of licensing are acceptable.

  • How can I get the file I have open in vim to display in my iTerm tab

    - by dd
    I can get the vim title to display on my window by doing this: let &titlestring = expand("%:t") . " @ " . hostname() if &term == "screen" set t_ts=^[k set t_fs=^[\ endif if &term == "screen" || &term == "xterm" set title endif But the tabs will say "Default". From the commandline I can do this: echo -ne "\e]1;hello world\a" And that'll show "Hello World" in my tabs. Is there a way to have vim write this stuff to my tab instead of title instead?

  • Are there any Rails Plugins that use JS to poll the server for completion of a background process?

    - by btelles
    I know it might be simple to write some polling JS that asks the Rails application if it has completed a background job. But I wonder if anyone has already packaged up this functionality as a plugin. Basically, I have a few delayed_jobs running, and am looking for a plugin that will poll the server for completion of a particular job, then activate a callback when it finds that the job is complete. Any ideas anyone? Berns

  • Is it a bad practice to pass "this" as an argument?

    - by Anna Lear
    I'm currently tempted to write the following: public class Class1() { public Class1() { MyProperty = new Class2(this); } public Class2 MyProperty { get; private set; } } public class Class2() { public Class2(Class1 class1) { ParentClass1 = class1; } public Class1 ParentClass1 { get; set; } } Is passing "this" as an argument a sign of a design problem? What would be a better approach?

  • Html / Email / Distribution list problem from a noob

    - by Hezeus
    I need to create a feature for a website that will allow a user to enter their email in order to receive a free promotion (which will be emailed immediately) and be added to an announcement list. I haven't done any web programming and am wondering where I should start? Should I just create a database and everytime an email is entered, add the email to the database, then when I want to send out an announcement just write a script that will send an email to every address? Thanks!

  • Photoshop script to get the color of a solid fill layer?

    - by gruner
    I'm trying to write a Photoshop jsx script for extracting color values from a PSD template. The colors are defined as separate fill layers that I'd like to be able to loop through and create a hash of {layer_name: #hex_color} values. I'm not finding any documentation on reading the color value of the fill layer.

  • CLLocationManager ensure best accuracy for iphone

    - by Zap
    Does anyone have any suggestions on how to obtain the best horizontal accuracy on the location manager? I have set the desired accuracy to NearestTenMeters, but given that the accuracy can always change depending on coverage area, how can I write some code in the locationManager to stop updating only after I get the best horizontal accuracy?

  • Access external xml using xslt document function return 401

    - by Ciprian Grosu
    On MOSS2007, I have a webpart that display the content of a xml feed. I use a xslt with parameters for transforamtions. There is a situation when I receive a 401 Authorisation exception. I realize that this happen when a document() function from my xslt try to open an external xml. If I try to open this xml in browser all work ok. I provided my admin credentials to the web part and to the XmlSecureResolver. Same problem. The webpart is on server1 and the xml feed and external xml required by xslt is on server2. What can be ? protected override void RenderContents(HtmlTextWriter writer) { base.RenderContents(writer); if (string.IsNullOrEmpty(this.xmlUrl) || this.xmlResponseStream == null) return; try { XslCompiledTransform transform = new XslCompiledTransform(); if (UseXslt) { XmlTextReader stylesheet = null; try { SPSite site = new SPSite(xsltlUrl); SPWeb web = site.OpenWeb(); SPFile file = web.GetFile(xsltlUrl); if (file != null) { stylesheet = new XmlTextReader(file.OpenBinaryStream()); } } catch(Exception ex) { stylesheet = new XmlTextReader(xsltlUrl); } if (stylesheet != null) { transform.Load(stylesheet, new XsltSettings(true, true), GetAResolver()); } using (XmlReader reader = new XmlTextReader(this.xmlResponseStream)) { string theParams = xsltProperties; XsltArgumentList xslAgrs = GetXsltArgumentList(xsltProperties); XmlTextWriter results = new XmlTextWriter(writer.InnerWriter); if (UseProperties) { transform.Transform(reader, xslAgrs, results, GetASecureResolver()); } else { transform.Transform(reader, results); } reader.Close(); } } else { string feedAsString = null; using (StreamReader rssReader = new StreamReader(this.xmlResponseStream)) { feedAsString = rssReader.ReadToEnd(); writer.InnerWriter.Write(SPHttpUtility.HtmlEncode(feedAsString)); } } } catch (Exception ex) { writer.Write(ex.Message); if (this.xmlResponseStream != null) { this.xmlResponseStream.Close(); this.xmlResponseStream.Dispose(); } } } private static XmlSecureResolver GetASecureResolver() { // Create a secure resolver XmlSecureResolver resolver = new XmlSecureResolver(new XmlUrlResolver(), "http://externalservername.com/thesite/"); string proxyUserName = RssFeedUtility.GetConfigFileReader().ProxyUserName; string proxyUserPwd = RssFeedUtility.GetConfigFileReader().ProxyUserPassword; string proxyUserDomain = RssFeedUtility.GetConfigFileReader().ProxyUserDomain; resolver.Credentials = new NetworkCredential(proxyUserName, proxyUserPwd, proxyUserDomain); return resolver; }

  • Any specifications/docs around optimization of Google Apps Script, to avoid timeouts and "hangs"

    - by BruceM
    From my experience so far, it seems that if you write a script that makes lots of expensive calls close together, the functionality just "hangs", or you get inconsistent responses, and have to refresh the browser because sheets stop updating etc. Are there any docs or specs that clarify this, as releasing an app fr real-world use is not possible if users can expect it to work most of the time, and produce random results every now and then...

  • Objective C BitConverter Equivalent

    - by user352891
    Hi there, I'm wondering if there is an Objective C equivalent to .Net's BitConverter.GetBytes() method. For example, in C#, I can write something like this: byte[] lengthPrefix = BitConverter.GetBytes(message.length); What would the equivalent be in Objective C? Some example code would be greatly appreciated. Thanks in advance.

  • How to create a compiler in vb.net

    - by Cyclone
    Before answering this question, understand that I am not asking how to create my own programming language, I am asking how, using vb.net code, I can create a compiler for a language like vb.net itself. Essentially, the user inputs code, they get a .exe. By NO MEANS do I want to write my own language, as it seems other compiler related questions on here have asked. I also do not want to use the vb.net compiler itself, nor do I wish to duplicate the IDE. The exact purpose of what I wish to do is rather hard to explain, but all I need is a nudge in the right direction for writing a compiler (from scratch if possible) which can simply take input and create a .exe. I have opened .exe files as plain text before (my own programs) to see if I could derive some meaning from what I assumed would be human readable text, yet I was obviously sorely disappointed to see the random ascii, though it is understandable why this is all I found. I know that a .exe file is simply lines of code, being parsed by the computer it is on, but my question here really boils down to this: What code makes up a .exe? How could I go about making one in a plain text editor if I wanted to? (No, I do not want to do that, but if I understand the process my goals will be much easier to achieve.) What makes an executable file an executable file? Where does the logic of the code fit in? This is intended to be a programming question as opposed to a computer question, which is why I did not post it on SuperUser. I know plenty of information about the System.IO namespace, so I know how to create a file and write to it, I simply do not know what exactly I would be placing inside this file to get it to work as an executable file. I am sorry if this question is "confusing", "dumb", or "obvious", but I have not been able to find any information regarding the actual contents of an executable file anywhere. One of my google searches Something that looked promising EDIT: The second link here, while it looked good, was an utter fail. I am not going to waste hours of my time hitting keys and recording the results. "Use the "Alt" and the 3-digit combinations to create symbols that do not appear on the keyboard but that you need in the program." (step 4) How the heck do I know what symbols I need??? Thank you very much for your help, and my apologies if this question is a nooby or "bad" one. To sum this up simply: I want to create a program in vb.net that can compile code in a particular language to a single executable file. What methods exist that can allow me to do this, and if there are none, how can I go about writing my own from scratch?

  • Most idiomatic way to print a time difference in Java?

    - by Zombies
    I'm familiar with printing time difference in milliseconds: long time = System.currentTimeMillis(); //do something that takes some time... long completedIn = System.currentTimeMillis() - time(); But, is there a nice way print a complete time in a specified format (eg: HH:MM:SS) either using Apache Commons or even the dreaded platform API's Date/Time objects? In other words, what is the shortest, simplest, no nonsense way to write this in Java?

  • Python form POST using urllib2 (also question on saving/using cookies)

    - by morpheous
    I am trying to write a function to post form data and save returned cookie info in a file so that the next time the page is visited, the cookie information is sent to the server (i.e. normal browser behavior). I wrote this relatively easily in C++ using curlib, but have spent almost an entire day trying to write this in Python, using urllib2 - and still no success. This is what I have so far: import urllib, urllib2 import logging # the path and filename to save your cookies in COOKIEFILE = 'cookies.lwp' cj = None ClientCookie = None cookielib = None logger = logging.getLogger(__name__) # Let's see if cookielib is available try: import cookielib except ImportError: logger.debug('importing cookielib failed. Trying ClientCookie') try: import ClientCookie except ImportError: logger.debug('ClientCookie isn\'t available either') urlopen = urllib2.urlopen Request = urllib2.Request else: logger.debug('imported ClientCookie succesfully') urlopen = ClientCookie.urlopen Request = ClientCookie.Request cj = ClientCookie.LWPCookieJar() else: logger.debug('Successfully imported cookielib') urlopen = urllib2.urlopen Request = urllib2.Request # This is a subclass of FileCookieJar # that has useful load and save methods cj = cookielib.LWPCookieJar() login_params = {'name': 'anon', 'password': 'pass' } def login(theurl, login_params): init_cookies(); data = urllib.urlencode(login_params) txheaders = {'User-agent' : 'Mozilla/4.0 (compatible; MSIE 5.5; Windows NT)'} try: # create a request object req = Request(theurl, data, txheaders) # and open it to return a handle on the url handle = urlopen(req) except IOError, e: log.debug('Failed to open "%s".' % theurl) if hasattr(e, 'code'): log.debug('Failed with error code - %s.' % e.code) elif hasattr(e, 'reason'): log.debug("The error object has the following 'reason' attribute :"+e.reason) sys.exit() else: if cj is None: log.debug('We don\'t have a cookie library available - sorry.') else: print 'These are the cookies we have received so far :' for index, cookie in enumerate(cj): print index, ' : ', cookie # save the cookies again cj.save(COOKIEFILE) #return the data return handle.read() # FIXME: I need to fix this so that it takes into account any cookie data we may have stored def get_page(*args, **query): if len(args) != 1: raise ValueError( "post_page() takes exactly 1 argument (%d given)" % len(args) ) url = args[0] query = urllib.urlencode(list(query.iteritems())) if not url.endswith('/') and query: url += '/' if query: url += "?" + query resource = urllib.urlopen(url) logger.debug('GET url "%s" => "%s", code %d' % (url, resource.url, resource.code)) return resource.read() When I attempt to log in, I pass the correct username and pwd,. yet the login fails, and no cookie data is saved. My two questions are: can anyone see whats wrong with the login() function, and how may I fix it? how may I modify the get_page() function to make use of any cookie info I have saved ?

  • failsafe jQuery code

    Can anyone explain what the jquery documentation is exactly referring to with this statement: "the argument to write failsafe jQuery code using the $ alias, without relying on the global alias" when referring to using the following: jQuery(function($) { }); I have been using jquery for a while now so understand what this code is doing to a certain extent but the phrase used in the documentation about writing failsafe jquery code puzzles me and i am unsure whether it is important or not.
