  • Custom Navigation Bar (html/css) for a website

    - by MikeStardust
    I am making a website and though of a cool navigation bar that is suppose to look like this: And using css code: #navigation ul { list-style: none; text-align: center; } #navigation li { display: inline; } #navigation li a { text-indent: -5000px; display: inline-block; height: 40px; } #navigation li a.profile { width: 240px; background: url("http://i.imgur.com/pphPRAA.png"); text-decoration: none; } #navigation li a.profile:hover { background: url("http://i.imgur.com/bDwcbXd.png"); background-position: -240px; text-decoration: none; } #navigation li a.profile:current { background: url("http://i.imgur.com/bDwcbXd.png"); background-position: -240px; background-repeat: no-repeat; text-decoration: none; } I managed to make it look like this: http://pokemasters.freeiz.com/bare.html I just ran out of ideas.... i got the images that i made seperatly, a navbar: & buttons: I'm looking for a full width navbar that adjusts itself to different screens, is located at the bottom of the screen, red buttons while active or hovered and white buttons while normal, with that pokeball line right on top of it and overlaying the buttons Can someone point me in the right direction please?? thank you:)

  • Using the Queue class in Python 2.6

    - by voipme
    Let's assume I'm stuck using Python 2.6, and can't upgrade (even if that would help). I've written a program that uses the Queue class. My producer is a simple directory listing. My consumer threads pull a file from the queue, and do stuff with it. If the file has already been processed, I skip it. The processed list is generated before all of the threads are started, so it isn't empty. Here's some pseudo-code. import Queue, sys, threading processed = [] def consumer(): while True: file = dirlist.get(block=True) if file in processed: print "Ignoring %s" % file else: # do stuff here dirlist.task_done() dirlist = Queue.Queue() for f in os.listdir("/some/dir"): dirlist.put(f) max_threads = 8 for i in range(max_threads): thr = Thread(target=consumer) thr.start() dirlist.join() The strange behavior I'm getting is that if a thread encounters a file that's already been processed, the thread stalls out and waits until the entire program ends. I've done a little bit of testing, and the first 7 threads (assuming 8 is the max) stop, while the 8th thread keeps processing, one file at a time. But, by doing that, I'm losing the entire reason for threading the application. Am I doing something wrong, or is this the expected behavior of the Queue/threading classes in Python 2.6?

  • Display X divs randomly out of a possible Y.

    - by Jordan
    How do I randomly display 3 divs out of a possible 10 in total? This is what I have tried so far: HTML: <div id="1">Content 1</div> <div id="2">Content 2</div> <div id="3">Content 3</div> <div id="4">Content 4</div> <div id="5">Content 5</div> <div id="6">Content 6</div> Javascript: function randomiseDiv() { // Define how many divs we have var divCount = 6; // Get our random ID (based on the total above) var randomId = Math.floor(Math.random()*divCount+1); // Get the div that's been randomly selectted var chosenDiv= document.getElementById(randomId); // If the content is available on the page if (chosenDiv) { // Update the display chosenDiv.style.display = 'block'; } } window.onload = randomiseDiv; I would prefer a PHP solution, although anything at this stage would be beneficial.

  • Building A True Error Handler

    - by Kevin Pirnie
    I am trying to build an error handler for my desktop application. The code Is in the class ZipCM.ErrorManager listed below. What I am finding is that the outputted file is not giving me the correct info for the StackTrace. Here is how I am trying to use it: Try '... Some stuff here! Catch ex As Exception Dim objErr As New ZipCM.ErrorManager objErr.Except = ex objErr.Stack = New System.Diagnostics.StackTrace(True) objErr.Location = "Form: SelectSite (btn_SelectSite_Click)" objErr.ParseError() objErr = Nothing End Try Here is the class: Imports System.IO Namespace ZipCM Public Class ErrorManager Public Except As Exception Public Location As String Public Stack As System.Diagnostics.StackTrace Public Sub ParseError() Dim objFile As New StreamWriter(Common.BasePath & "error_" & FormatDateTime(DateTime.Today, DateFormat.ShortDate).ToString().Replace("\", "").Replace("/", "") & ".log", True) With objFile .WriteLine("-------------------------------------------------") .WriteLine("-------------------------------------------------") .WriteLine("An Error Occured At: " & DateTime.Now) .WriteLine("-------------------------------------------------") .WriteLine("LOCATION:") .WriteLine(Location) .WriteLine("-------------------------------------------------") .WriteLine("FILENAME:") .WriteLine(Stack.GetFrame(0).GetFileName()) .WriteLine("-------------------------------------------------") .WriteLine("LINE NUMBER:") .WriteLine(Stack.GetFrame(0).GetFileLineNumber()) .WriteLine("-------------------------------------------------") .WriteLine("SOURCE:") .WriteLine(Except.Source) .WriteLine("-------------------------------------------------") .WriteLine("MESSAGE:") .WriteLine(Except.Message) .WriteLine("-------------------------------------------------") .WriteLine("DATA:") .WriteLine(Except.Data.ToString()) End With objFile.Close() objFile = Nothing End Sub End Class End Namespace What is happenning is the .GetFileLineNumber() is getting the line number from 'objErr.Stack = New System.Diagnostics.StackTrace(True)' inside my Try..Catch block. In fact, it's the exact line number that is on. Any thoughts of what is going on here, and how I can catch the real line number the error is occuring on?

  • how to set style through javascript in IE immediately

    - by rezna
    Hi, recently I've encountered a problem with IE. I have a function function() { ShowProgress(); DoSomeWork(); HideProgress(); } where ShowProgress and HideProgress just manipulate the 'display' CSS style using jQuery's css() method. In FF everything is OK, and at the same time I change the display property to block, progress-bar appears. But not in IE. In IE the style is applied, once I leave the function. Which means it's never shown, because at the end of the function I simply hide it. (if I remove the HideProgress line, the progress-bar appears right after finishing executing the function (more precisely, immediately when the calling functions ends - and so there's nothing else going on in IE)). Has anybody encountered this behavior? Is there a way to get IE to apply the style immediately? I've prepared a solution but it would take me some time to implement it. My DoSomeWork() method is doing some AJAX calls, and these are right now synchronous. I assume that making them asynchronous will kind of solve the problem, but I have to redesign the code a bit, so finding a solution just for applying the style immediately would much simplier. Thanks rezna

    I want to make a jquery version of this css3 effect so that it also works in ff and ie: a:hover {color: #354250; -webkit-transition:background 500ms ease-in;} a.more:hover, a.more:focus, a.more:active {background-position: 0 -18px;} a.more:link, a.more:visited { background: url(images/moreButton.png) no-repeat 0 0; display: inline-block; height:18px; margin-top:10px; text-indent: -9999px; width:77px; } My tries didn't work, here is what I' ve got so far. $("a.more").hover(function() { $(this).stop().animate({ color: '#354250', backgroundPosition: '0px -18px' }, slow, function() { $(this).stop().animate({ color: '#ad5332', backgroundPosition: '0px 0px'}, 0); }); }, function() { $(this).stop().animate({ color: '#ad5332', backgroundPosition: '0px 0px' }, 0); }); Do you have any idea how to fix this? Thank you very much!

  • Progressively stream the output of an ASP.NET page - or render a page outside of an HTTP request

    - by Evgeny
    I have an ASP.NET 2.0 page with many repeating blocks, including a third-party server-side control (so it's not just plain HTML). Each is quite expensive to generate, in terms of both CPU and RAM. I'm currently using a standard Repeater control for this. There are two problems with this simple approach: The entire page must be rendered before any of it is returned to the client, so the user must wait a long time before they see any data. (I write progress messages using Response.Write, so there is feedback, but no actual results.) The ASP.NET worker process must hold everything in memory at the same time. There is no inherent needs for this: once one block is processed it won't be changed, so it could be returned to the client and the memory could be freed. I would like to somehow return these blocks to the client one at a time, as each is generated. I'm thinking of extracting the stuff inside the Repeater into a separate page and getting it repeatedly using AJAX, but there are some complications involved in that and I wonder if there is some simper approach. Ideally I'd like to keep it as one page (from the client's point of view), but return it incrementally. Another way would be to do something similar, but on the server: still create a separate page, but have the server access it and then Response.Write() the HTML it gets to the response stream for the real client request. Is there a way to avoid an HTTP request here, though? Is there some ASP.NET method that would render a UserControl or a Page outside of an HTTP request and simply return the HTML to me as a string? I'm open to other ideas on how to do this as well.

  • Is memory allocation in linux non-blocking?

    - by Mark
    I am curious to know if the allocating memory using a default new operator is a non-blocking operation. e.g. struct Node { int a,b; }; ... Node foo = new Node(); If multiple threads tried to create a new Node and if one of them was suspended by the OS in the middle of allocation, would it block other threads from making progress? The reason why I ask is because I had a concurrent data structure that created new nodes. I then modified the algorithm to recycle the nodes. The throughput performance of the two algorithms was virtually identical on a 24 core machine. However, I then created an interference program that ran on all the system cores in order to create as much OS pre-emption as possible. The throughput performance of the algorithm that created new nodes decreased by a factor of 5 relative the the algorithm that recycled nodes. I'm curious to know why this would occur. Thanks. *Edit : pointing me to the code for the c++ memory allocator for linux would be helpful as well. I tried looking before posting this question, but had trouble finding it.

  • Div at bottom of window and adaptable height div

    - by Rob
    Is there a way to get a div to always be at the bottom of the window, and another div to change its height to fill any space that it leaves, and that div will scroll if its content is too long. (I never want the window to scroll). This is best illustrated by a picture: The green div will always put itself at the bottom of the window, and the orange div will fill the gap. When the window is smaller, like in the right hand image, the orange div will be smaller and will scroll. The green div can be toggled. Sometimes the green div will have display: none, and then the orange div will stretch to the bottom. When the green div has display: block again, it will look like the picture again. It has to work in IE6. So far I can get the green div to go to the bottom by: position: absolute; bottom: 0; But I don't know how to get the orange div to do what I want.

  • iptables : how to allow incoming ftp traffic?

    - by logansama
    Hi, Still fighting my way through the jungle that is called iptables. I have managed to allow FTP access outside of our LAN: both these would work. NOTE: eth0 is the LAN interface and eth1 is the WAN interface. iptables -t filter -A FORWARD -i eth0 -p tcp --dport 20:21 -j ACCEPT or iptables -A FORWARD -i eth0 -o eth1 -p tcp --sport 20:21 --dport 1024:65535 -j ACCEPT But when i connect to a external FTP server i manage to log in and all is fine until it wishes to List the directory content. Then nothing happens as the data is blocked, due to the fact that i do not have a rule set up to allow it! (my last rule on the FORWARD chain is to block all traffic) I have tried a gazillion rules (many of which i did not understand) to try and allow the FTP traffic back through my server. One such rule for example was: iptables -A FORWARD -i eth1 -o eth0 -p tcp --sport 20:21 --dport 1024:65535 -j ACCEPT But i cannot get the List to work. It just times out after a while. Would anyone perhaps know how to build a rule which would allow FTP to List / allow such traffic back? Or have a link to sources i could work through? Thank you,

  • AngularJS - $routeParams Empty on $locationChangeSuccess

    - by Marc M.

  • Trie Backtracking in Recursion

    - by Darksky
    I am building a tree for a spell checker with suggestions. Each node contains a key (a letter) and a value (array of letters down that path). So assume the following sub-trie in my big trie: W / \ a e | | k k | | is word--> e e | ... This is just a subpath of a sub-trie. W is a node and a and e are two nodes in its value array etc... At each node, I check if the next letter in the word is a value of the node. I am trying to support mistyped vowels for now. So 'weke' will yield 'wake' as a suggestion. Here's my searchWord function in my trie: def searchWord(self, word, path=""): if len(word) > 0: key = word[0] word = word[1:] if self.values.has_key(key): path = path + key nextNode = self.values[key] return nextNode.searchWord(word, path) else: # check here if key is a vowel. If it is, check for other vowel substitutes else: if self.isWord: return path # this is the word found else: return None Given 'weke', at the end when word is of length zero and path is 'weke', my code will hit the second big else block. weke is not marked as a word and so it will return with None. This will return out of searchWord with None. To avoid this, at each stack unwind or recursion backtrack, I need to check if a letter is a vowel and if it is, do the checking again. I changed the if self.values.has_key(key) loop to the following: if self.values.has_key(key): path = path + key nextNode = self.values[key] ret = nextNode.searchWord(word, path) if ret == None: # check if key == vowel and replace path # return nextNode.searchWord(... return ret What am I doing wrong here? What can I do when backtracking to achieve what I'm trying to do?

  • ZeroMQ REQ/REP on ipc:// and concurrency

    - by Metiu
    I implemented a JSON-RPC server using a REQ/REP 0MQ ipc:// socket and I'm experiencing strange behavior which I suspect is due to the fact that the ipc:// underlying unix socket is not a real socket, but rather a single pipe. From the documentation, one has to enforce strict zmq_send()/zmq_recv() alternation, otherwise the out-of-order zmq_send() will return an error. However, I expected the enforcement to be per-client, not per-socket. Of course with a Unix socket there is just one pipeline from multiple clients to the server, so the server won't know who it is talking with. Two clients could zmq_send() simultaneously and the server would see this as an alternation violation. The sequence could be: ClientA: zmq_send() ClientB: zmq_send() : will it block until the other send/receive completes? will it return -1? (I suspect it will with ipc:// due to inherent low-level problems, but with TCP it could distinguish the two clients) ClientA: zmq_recv() ClientB: zmq_recv() so what about tcp:// sockets? Will it work concurrently? Should I use some other locking mechanism to work around this?

  • CompositionHost.Initialize() can not execute twice.

    - by Khoa
    I am currently try to integrate MEF and PRISM to work with each other. Everything is working fine so far. Now i would like to use MEF runtime module discovery (DeploymentCatalog) which will be used to download XAPs from server directory and then plug it into one of the Region inside my MAIN UI. I am using UnityBootStrapper and inside this class i also integrated MEF container. This sample application is based on Glenn Block (http://codebetter.com/glennblock/2010/01/03/mef-and-prism-exploration-mef-module-loading/). The following code is used to initialize CompositionContainer inside my Bootstrapper: // This is the host catalog which contains all parts of running assembly. var catalog = GetHostCatalog(); // Create MEF container which initial catalog var container = new CompositionContainer(catalog); // here we explicitly map a part to make it available on imports elsewhere, using // Unity to resolve the export so dependencies are resolved // We do this because region manager is third-party ... therefore, we need to // export explicitly because the implementation doesn't have its own [export] tag container.ComposeExportedValue<IRegionManager>(Container.Resolve<IRegionManager>()); container.ComposeExportedValue<IEventAggregator>(Container.Resolve<IEventAggregator>()); // Obtain CatalogService as a singleton // All dynamic modules will use this service to add its parts. Container.RegisterInstance<ICatalogService>(new CatalogService(catalog)); // Initialize the container CompositionHost.Initialize(container); Now i have another class called DeploymentCatalogService which is used to download the XAP from server. The current problem i am facing is that inside DeploymentCatalogService Initialize method, CompositionHost container is try to initialize its container with aggregateCatalog again. _aggregateCatalog = new AggregateCatalog(); _aggregateCatalog.Catalogs.Add(new DeploymentCatalog()); CompositionHost.Initialize(_aggregateCatalog); This causes an Exception which stated that The container has already been initialized. Is there a way to use the existing container and update it with the new aggregateCatalog? Hope this is not too confusing. Please be nice i am still new to MEF. Cheers,

  • odd behavior with C# ftp client class

    - by geoff
    I found an ftp client class in c# over a year ago and have been using it in a process that uploads files on a nightly basis. A few days ago we started having a problem where it would time out. I'm not well versed in this so I'm not sure why it's doing this. When the program starts uploading a file it checks to see if it's logged in and if not, it calls the login method. In that method is this block of code. if (this.resultCode != 230) { this.sendCommand("PASS " + password); if (!(this.resultCode == 230 || this.resultCode == 202)) { this.cleanup(); throw new FtpException(this.result.Substring(4)); } } On the line that says this.sendCommand("PASS"... it goes into this code. private void sendCommand(String command) { if (this.verboseDebugging) Debug.WriteLine(command, "FtpClient"); Byte[] cmdBytes = Encoding.ASCII.GetBytes((command + "\r\n").ToCharArray()); clientSocket.Send(cmdBytes, cmdBytes.Length, 0); this.readResponse(); } If I let the program run, it times out. However if I step through it into the sendCommand method it executes fine. Does anyone know why it would work fine when I step through it? Nothing on our end has changed and I've been told nothing on the client's end has changed so I'm stumped. Thanks.

  • Drupal: allowing users to sign up to content using a form

    - by james6848
    My apologies if this is a little broad, but I'm struggling to know where to start here! OK, so I have a Drupal site and I need users to be able to sign up for certain content, here is the workflow in detail: I need a form within a block consisting of the following elements: First Name (required) Last Name (required) Organisation (optional) Email Address (required) Then there will be a choice of content to sign up to (using checkboxes): Policy Bulletin Action News eBulletin (which only members can sign up to) Then the usual submit button of course! Upon submission, users will: 1) Be taken to a confirmation page, or 2) Be informed about incorrectly filled in fields, and/or the need to become a user to be able to sign up for the eBulletin. Users will then receive an email when new content of the type(s) they signed up to is created, along with a link to the node. There should be details about how to unsubscribe within this email. I have used the Subscriptions module in the past, but I am not sure if it is possible to use a sign-up form with it. Plus, there is the added complexity that one of the content types, eBulletin, is only available for site members. Like I say, I'm struggling to know where to start, and any ideas would be gratefully received!

  • Initializing Disqus comments in hidden element causes issue in FF 14.0.1

    - by Bazze
    This issue appears only in Firefox 14.0.1 (well I couldn't reproduce it in any other browser). If you put the code for Disqus comments inside an element that is hidden and wait until everything is fully loaded and then display the element using JavaScript, the comment box nor comments will show up. However if you resize the window, it'll show up immediately. It's working fine in latest version of Google Chrome and Safari though. What's causing this and how to fix it? Sample code to reproduce: <div id="test" style="display:none;"> <div id="disqus_thread"></div> <script type="text/javascript"> /* * * CONFIGURATION VARIABLES: EDIT BEFORE PASTING INTO YOUR WEBPAGE * * */ var disqus_shortname = 'onlinefunctions'; // required: replace example with your forum shortname /* * * DON'T EDIT BELOW THIS LINE * * */ (function() { var dsq = document.createElement('script'); dsq.type = 'text/javascript'; dsq.async = true; dsq.src = 'http://' + disqus_shortname + '.disqus.com/embed.js'; (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(dsq); })(); </script> <noscript>Please enable JavaScript to view the <a href="http://disqus.com/?ref_noscript">comments powered by Disqus.</a></noscript> <a href="http://disqus.com" class="dsq-brlink">comments powered by <span class="logo-disqus">Disqus</span></a> </div> <a href="#" onclick="document.getElementById('test').style.display = 'block'">show</a> I could post a link to a live example but I'm not sure about the policy of posting links here on Stack Overflow.

  • [solved] IE6 PNG-transparency CSS hack not working

    - by John
    I looked around and decided to use a CSS approach rather than rely on JS... I figure the kind of corporate users stuck with IE6 might also have JS disabled by IT departments. So In my HTML I have: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html;charset=utf-8" /> <title>My Page</title> <link rel="stylesheet" type="text/css" href="default.css" /> <!--[if IE 6]><link rel="stylesheet" type="text/css" href="ie6.css"><![endif]--> </head> <body> <img src="media/logo.png"/> </body> Then my ie6.css consists simply of: img { filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(...); } However none of this makes the slightest difference, no transparency. I commented out all the rest of the page so it is literally that one and still no luck. I removed the default.css stylesheet and still no difference. EDIT: I now got it working, using the .htc method, loading that file in a conditional IE6 test block. It turned out the problem I was having was that Windows 7 had 'locked' the file (I don't even know what this means) and this blocked IE from loading/using it.

  • Java Collection performance question

    - by Shervin
    I have created a method that takes two Collection<String> as input and copies one to the other. However, I am not sure if I should check if the collections contain the same elements before I start copying, or if I should just copy regardless. This is the method: /** * Copies from one collection to the other. Does not allow empty string. * Removes duplicates. * Clears the too Collection first * @param target * @param dest */ public static void copyStringCollectionAndRemoveDuplicates(Collection<String> target, Collection<String> dest) { if(target == null || dest == null) return; //Is this faster to do? Or should I just comment this block out if(target.containsAll(dest)) return; dest.clear(); Set<String> uniqueSet = new LinkedHashSet<String>(target.size()); for(String f : target) if(!"".equals(f)) uniqueSet.add(f); dest.addAll(uniqueSet); } Maybe it is faster to just remove the if(target.containsAll(dest)) return; Because this method will iterate over the entire collection anyways.

  • CSS with Aligned LI within a UL

    I am trying to have some LIs within a UL align left, right, and center within a page. For the life of me, I can't figure out how to keep something "centered" on the same line as a left and right aligned LI. <style> ul { margin:1em 0; padding:0 } ul li{ display:inline-block; white-space:nowrap; margin:5px } ul li.left{ float: left; text-align:left; } ul li.center{ float:left; text-align: center; } ul li.right{ float: right; text-align:right; } </style> <ul> <li class="left">left</li> <li class="center">center</li> <li class="right">right</li> </ul> <ul> <li class="left">left</li> <li class="right">right</li> </ul> <ul> <li class="left">left</li> </ul> Can anyone help? BTW, I've trying to avoid DIVs. Thanks!

  • python os.mkfifo() for Windows

    - by user302099
    Hello. Short version (if you can answer the short version it does the job for me, the rest is mainly for the benefit of other people with a similar task): In python in Windows, I want to create 2 file objects, attached to the same file (it doesn't have to be an actual file on the hard-drive), one for reading and one for writing, such that if the reading end tries to read it will never get EOF (it will just block until something is written). I think in linux os.mkfifo() would do the job, but in Windows it doesn't exist. What can be done? (I must use file-objects). Some extra details: I have a python module (not written by me) that plays a certain game through stdin and stdout (using raw_input() and print). I also have a Windows executable playing the same game, through stdin and stdout as well. I want to make them play one against the other, and log all their communication. Here's the code I can write (the get_fifo() function is not implemented, because that's what I don't know to do it Windows): class Pusher(Thread): def __init__(self, source, dest, p1, name): Thread.__init__(self) self.source = source self.dest = dest self.name = name self.p1 = p1 def run(self): while (self.p1.poll()==None) and\ (not self.source.closed) and (not self.source.closed): line = self.source.readline() logging.info('%s: %s' % (self.name, line[:-1])) self.dest.write(line) self.dest.flush() exe_to_pythonmodule_reader, exe_to_pythonmodule_writer =\ get_fifo() pythonmodule_to_exe_reader, pythonmodule_to_exe_writer =\ get_fifo() p1 = subprocess.Popen(exe, shell=False, stdin=subprocess.PIPE, stdout=subprocess.PIPE) old_stdin = sys.stdin old_stdout = sys.stdout sys.stdin = exe_to_pythonmodule_reader sys.stdout = pythonmodule_to_exe_writer push1 = Pusher(p1.stdout, exe_to_pythonmodule_writer, p1, '1') push2 = Pusher(pythonmodule_to_exe_reader, p1.stdin, p1, '2') push1.start() push2.start() ret = pythonmodule.play() sys.stdin = old_stdin sys.stdout = old_stdout

  • template files evaluation in python

    - by saminny
    I am trying to use python for translating a set of templates to a set of configuration files based on values taken from a main configuration file. However, I am having certain issues. Consider the following example of a template file. file1.cfg.template %(CLIENT1)s %(HOST1)s %(PORT1)d C %(COMPID1)s %(CLIENT2)s %(HOST2)s %(PORT2)d C %(COMPID2)s This file contains an entry for each client. There are hundreds of config files like this and I don't want to have logic for each type of config file. Python should do the replacements and generate config files automatically given a set of global values read from a main xml config file. However, in the above example, if CLIENT2 does not exist, how do I delete that line? I expect Python would generate the config file using something like this: os.open("file1.cfg.template").read() % myhash where myhash is hash of configuration parameters from the main config file which may not contain CLIENT2 at all. In the case it does not contain CLIENT2, I want that line to disappear from the file. Is it possible to insert some 'IF' block in the file and have python evaluate it? Thanks for your help. Any suggestions most welcome.

  • GetAccessControl error with NTAccount

    - by Adam Witko
    private bool HasRights(FileSystemRights fileSystemRights_, string fileName_, bool isFile_) { bool hasRights = false; WindowsIdentity WinIdentity = System.Security.Principal.WindowsIdentity.GetCurrent(); WindowsPrincipal WinPrincipal = new WindowsPrincipal(WinIdentity); AuthorizationRuleCollection arc = null; if (isFile_) { FileInfo fi = new FileInfo(@fileName_); arc = fi.GetAccessControl().GetAccessRules(true, true, typeof(NTAccount)); } else { DirectoryInfo di = new DirectoryInfo(@fileName_); arc = di.GetAccessControl().GetAccessRules(true, true, typeof(NTAccount)); } foreach (FileSystemAccessRule rule in arc) { if (WinPrincipal.IsInRole(rule.IdentityReference.Value)) { if (((int)rule.FileSystemRights & (int)fileSystemRights_) > 0) { if (rule.AccessControlType == AccessControlType.Allow) hasRights = true; else if (rule.AccessControlType == AccessControlType.Deny) { hasRights = false; break; } } } } return hasRights; } The above code block is causing me problems. When the WinPrincipal.IsInRole(rule.IdentityReference.Value) is executed the following exception occurs: "The trust relationship between the primary domain and the trusted domain failed.". I'm very new to using identities, principles and such so I don't know what's the problem. I'm assuming it's with the use of NTAccount? Thanks
