  • 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...

  • ASP MVC: Custom Validation Attribute

    - by user323395
    I'm trying to write my own Custom Validation attribute but i'm having some problems. The attribute i'm trying to write is that when a user logs in, the password will be compared against the confirmation password. namespace EventCompanion.Data.Attributes { public class ComparePassword : ValidationAttribute { public string PasswordToCompareWith { get; set; } public override bool IsValid(object value) { if (PasswordToCompareWith == (string)value) { return true; } return false; } } Now my problem is when i'm trying to set the attribute like this in the model file: [Required] [ComparePassword(PasswordToCompareWith=ConfirmPassword)] public string Password { get; set; } [Required] public string ConfirmPassword { get; set; } } I get the following error: Error 1 An object reference is required for the non-static field, method, or property 'Project.Data.Models.GebruikerRegistreerModel.ConfirmPassword.get' It seems that VS is not accepting the confirmpassword in the "PasswordToCompareWith=ConfirmPassword" part Now my question: What am i doing wrong? Thanks in advance!!!

  • Counting viable sublist lengths from an array.

    - by Ben B.
    This is for a genetic algorithm fitness function, so it is important I can do this as efficiently as possible, as it will be repeated over and over. Lets say there is a function foo(int[] array) that returns true if the array is a "good" array and false if the array is a "bad" array. What makes it good or bad does not matter here. Given the full array [1,6,8,9,5,11,45,16,9], lets say that subarray [1,6,8] is a "good" array and [9,5,11,45] is a "good" array. Furthermore [5,11,45,16,9] is a "good" array, and also the longest "good" subarray. Notice that while [9,5,11,45] is a "good" array, and [5,11,45,16,9] is a "good" array, [9,5,11,45,16,9] is a "bad" array. We wants the length counts of all "good" arrays, but not subarrays of "good" arrays. Furthermore, as described above, a "good" array might begin in the middle of another "good" array, but the combination of the two might be a "bad" array.

  • Doesn't get into Debug Mode

    - by Grace Jones
    When I Press F5 on my VS2005 to debug the application, it launches the web app window but it is coming out of debug mode. When I tried to trace the Error in the EventViewer, this was the error: Failed in Token.vb(GetToken). The token was not in memory and the identity of the authenticated IIS caller was not permitted. The session may have unexpectedly terminated. The specific error message included: Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the \\ section in the application configuration. I don't have any httpModules section in my config file and the sessionState mode="InProc"...

  • Problem with operator ==

    - by CPPDev
    I am facing some problem with use of operator == in the following c++ program. #include < iostream> using namespace std; class A { public: A(char *b) { a = b; } A(A &c) { a = c.a; } bool operator ==(A &other) { return strcmp(a, other.a); } private: char *a; }; int main() { A obj("test"); A obj1("test1"); if(obj1 == A("test1")) { cout<<"This is true"<<endl; } } What's wrong with if(obj1 == A("test1")) line ?? Any help is appreciated.

  • Java BufferedReader readline blocking?

    - by tgguy
    I want to make an HTTP request and then get the response as sketched here: URLConnection c = new URL("http://foo.com").openConnection(); c.setDoOutput(true); /* write an http request here using a new OutputStreamWriter(c.getOutputStream) */ BufferedReader reader = new BufferedReader(new InputStreamReader(c.getInputStream)); reader.readLine(); But my question is, if the request I send takes a long time before a response is received, what happens in the call reader.readLine() above? Will this process stay running/runnable on the CPU or will it get taken off the CPU and be notified to wake up and run again when there is IO to be read? If it stays on the CPU, what can be done to make it get off and be notified later?

  • CodedUI null reference exception even when object exists

    - by Roee
    Hi, I have created a coded ui test that checks something in my software. It worked fine, but now I keep getting null reference exception when I try to interact with the UITestControl. The starnge thing is, that the UITestControl's 'Exist' property returns true, which means that the control had been found. I've searched and found this topic: http://social.msdn.microsoft.com/Forums/en/vsautotest/thread/c2e6e5c3-2503-4506-9963-733fd84fbd25, But I have checked in my project, and the 'Copy Local' propert of these assemblies is set to false. I think that this execption first occurred after I have added an app.config file to my project. Maybe this might be the problem? If so, how can I fix this without deleting my app.config file? Thanks!

  • Wordpress TinyMCE keeps it clean, how?

    - by Frankie
    I've noticed that the latest version of TinyMCE on Wordpress manages text in a very 'clean' way. Pasting from MS-Word it strips out all html text blocks, like <p>'s, and shows the text cleared of any odd formatting preserving only links, bolds and underlines. On top of that the source code format is very clear. No <br />'s everywhere. You only see \n's and the expected <strong><u><i> tags. I've been messing up with TinyMCE configuration files for some time with little success. I did manage to get all formatting removed. I can't, however, put TinyMCE to display the \n's as <br />'s lie Wordpress does it. Tried preformatted : true with no success whatsoever. Has anyone here been able to do it? Thank you in advance, Francisco

  • Guaranteed COM object release?

    - by Jurily
    I wrote the following code under the assumption that Excel will die with Monkey: class ExcelMonkey { private static Excel.Application xl = new Excel.Application(); public static bool parse(string filename) { if (filename.Contains("foo")) { var workbook = xl.Workbooks.Open(filename); var sheet = workbook.Worksheets.get_Item(1); // do stuff return true; } return false; } } How do I make sure it does? Do I need to release workbook and sheet separately? I want to have Excel around for the lifetime of the program, it's a huge performance improvement.

  • ViewStateMode property in Asp.Net 4.0

    - by AspOnMyNet
    I haven’t yet started learning Asp.Net 4.0, but I did read a bit on ViewState, where there is a new property ViewStateMode. In earlier versions of Asp.Net, if parent control had its ViewState disabled, then child controls also had their ViewState disabled, even if their EnableViewState was set to true. a) Thus if I understand it correctly, then a child control C having ViewStateMode property set to “Enable” causes C to save its view state, even if parent control has its view state disabled? b) Is there a reason why ViewStateMode property hasn’t/couldn’t be implemented in earlier versions of Asp.Net? thanx

  • Find directory on different server C#

    - by rainhider
    I have a website on Server A and it needs to find a directory on Server B. On my aspx page, I have: <mb:FileSystemDataSource ID="fileSystemDataSource" runat="server" RootPath="\\servername\Folder\Subfolder" FoldersOnly="true" /> mb is assembly name alias. On my aspx.cs page, I have: protected void Page_Load(object sender, EventArgs e) { DataTable gridviewSource = DisplayFilesInGridView(); DataRow gridviewRow; //sets the server path so it does not default to current server string ServerPath = System.IO.Path.Combine( "//", this.fileSystemDataSource.RootPath); //Get All Folders Or Directories and add in table DirectoryInfo directory = new DirectoryInfo(Server.MapPath(ServerPath)); DirectoryInfo[] subDirectories = directory.GetDirectories(); } Well, it throws an error on the Server.MapPath because it cannot find the server. I am connected to the network. I looked at IIS, and I am pretty sure that is not the problem. If so, I would really need specifics. Any help would be appreciated.

  • Any way to separate unit tests from integration tests in VS2008?

    - by AngryHacker
    I have a project full of tests, unit and integration alike. Integration tests require that a pretty large database be present, so it's difficult to make it a part of the build process simply because of the time that it takes to re-initialize the database. Is there a way to somehow separate unit tests from integration tests and have the build server just run the unit tests? I see that there is an Ordered Unit test in VS2008, which allows you to pick and choose tests, but I can't make it just execute alone, without all the others. Is there a trick that I am missing? Or perhaps I could adorn the unit tests with an attribute? What are some of the approaches people are using? P.S. I know I could use mocking for integration tests (just to make them go faster) but then it wouldn't be a true integration test.

  • Why am I getting such random results when checking DNS?

    - by animuson
    The code is as follows: $domain = "fosajfjdkgdajfhsd.com"; $check1 = checkdnsrr($domain, "MX"); $check2 = checkdnsrr($domain, "A"); $check3 = (checkdnsrr($domain, "MX") || checkdnsrr($domain, "A")); $check4 = !(checkdnsrr($domain, "MX") || checkdnsrr($domain, "A")); die("{$check1} - {$check2} - {$check3} - {$check4}"); However when I check the output to see what it's returning, I get this: - 1 - 1 - The domain obviously wouldn't exist, so I don't understand why checking the A record is return true and checking the MX result doesn't give me anything at all. I don't understand what's going wrong here.

Everything seems to work except the code I put in italic.

  • Using jQuery to create a video switcher

    - by techcastoni
    I've got a design for a video page which has a main video panel which will load the FLV file into JWPlayer when a thumbnail image is clicked. I think what I'm looking for is a partial page refresh? What is the best way to achieve this effect? This is the script I am using to display the video panel: var s1 = new SWFObject('player.swf','player','682','407','9'); s1.addParam('allowfullscreen','true'); s1.addParam('allowscriptaccess','always'); s1.addParam('flashvars','file=Welcome.f4v'); s1.write('preview');

  • When the Microsoft's main support phase for .NET 2.0, .NET 3.0 and .NET 3.5 ends?

    - by Martin Vobr from Rebex
    Hello, I'm wondering until when the .NET Framework 2.0, 3.0, 3.5 will be supported by Microsoft. According to Microsoft Support Lifetime page for developers products the mainstream support phase should last for 5 years and extended support phase for another 5 years. I've found a .NET Framework 2.0 entry in the Support Lifetime Index , however I was unable to find any entry for .NET 3.0 and .NET 3.5 there (or .NET 4.0). According to the .NET framework 2.0 entry mainstream support phase for .NET 2.0 will end at 4/12/2011. I have two questions: Considering that .NET 3.0 and .NET 3.5 depends on .NET 2.0 CLR does it means that mainstream support for .NET 3.x will also end in 4/12/2011? If it's not true what is the end of mainstream support for .NET 3.0 and .NET 3.5?

  • Facebook Social Plugins Like button returns "Website Inaccessible"

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

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

  • How to get a count of ManagementObjects (WMI results) without enumerating through the collection in

    - by Mark
    When querying for large ammount of data through WMI (say the windows events log Win32_NTLogEvent) it is very useful to know what kind of numbers you are getting yourself into before downloading all the content. Is there a way two do this? From what i know there is no "Select Count(*) FROM Win32_NTLogEvent" in WQL. From what i know the Count property of the ManagementObjectCollection actually enumerates through all the results whether you have the Rewindable property set to true or false. If it cannot be done in .NET, can it be done by directly using the underlying IWbem objects Thanks

  • Try to fill the GAE datastore but the code consumes to much cpu time. How to optimize this?

    - by Neverland
    I try to get the list of images in Amazon EC2 inside the Google datastore. I want to realize this with a cron job inside the GAE. class AmazonEC2uswest(db.Model): ami = db.StringProperty(required=True) mani = db.StringProperty() typ = db.StringProperty() arch = db.StringProperty() state = db.StringProperty() owner = db.StringProperty() class CronAMIsAmazonUS_WEST(webapp.RequestHandler): def get(self): aws_access_key_id_admin = "<secret>" aws_secret_access_key_admin = "<secret>" conn_us_west = boto.ec2.connect_to_region('us-west-1', aws_access_key_id=aws_access_key_id_admin, aws_secret_access_key=aws_secret_access_key_admin, is_secure = False) liste_images_us_west = conn_us_west.get_all_images() laenge_liste_images_us_west = len(liste_images_us_west) for i in range(laenge_liste_images_us_west): datastore_uswest_AMIs = AmazonEC2uswest(ami=liste_images_us_west[i].id, mani=str(liste_images_us_west[i].location), typ=liste_images_us_west[i].type, arch=liste_images_us_west[i].architecture, state=liste_images_us_west[i].state, owner=liste_images_us_west[i].ownerId) datastore_uswest_AMIs.put() The problem: Getting the list with get_all_images() lasts only a few seconds. But writing the data to the Google datastore needs way too much CPU time. My IBM T42p (P4M with 2GHz) needs for that piece of code approx. 1 Minute! Is it possible to optimize my code in a way that it needs fewer CPU time?

  • Zend_Form validation problem

    - by GrumpyCanuck
    I am having problems getting validation to work for a form built using Zend_Form. The idea is this: I have two dropdown. One is a list of players. The other is a list of free agents who play the same position as the player. I am using an onChange javascript callback to run some Ajax code that replaces the free agent list dropdown with a new one at the position of the player they've selected from the player dropdown. Now, perhaps this is the wrong way, but I built the form by creating an instance of Zend_Form and then creating all these setX methods that add elements to the form. My reasoning was that I wanted to display certain elements in specific places on the page, not just output $this-form on my template. The problem appears to be when I get the form post back, the validator seems to not know about the validation rule I set up for the free agent drop down. Here's some relevant code to look at. I'm a relative ZF n00b so feel free to tell me I am not doing things the ZF way if it leaps out at you. The action in the controller: public function indexAction() { if ($this->getRequest()->isPost()) { $form = new Baseball_Form_Transactions(); if ($form->isValid($this->_request->getPost())) { $data = $this->_request->getPost(); $leagueInfo = Doctrine::getTable('League')->findOneByShortName($data['shortLeagueName'])->toArray(); // Create the request top drop an existing player $transactionInfo = array( 'league_id' => $leagueInfo['id'], 'team_id' => $data['teamId'], 'player_id' => $data['players'], 'type' => 'drop', 'target_team_id' => 0, 'transaction_date' => date('Y-m-d H:m:s') ); $transaction = new Transaction(); $transaction->fromArray($transactionInfo); $transaction->save(); // Now we do the request to add a player $transactionInfo['team_id'] = 0; $transactionInfo['player_id'] = $data['freeAgents']; $transactionInfo['target_team_id'] = $data['teamId']; $transactionInfo['type'] = 'add'; $transaction = new Transaction(); $transaction->fromArray($transactionInfo); $transaction->save(); $this->_flashMessenger->addMessage('Added transaction'); } } $options = array( 'teamId' => $this->teamId, 'position' => 'C', 'leagueShortName' => $this->league ); $this->transactionForm->setMyPlayers($options); $this->transactionForm->setFreeAgents($options); $this->transactionForm->setTeamId($options); $this->transactionForm->setShortLeagueName($options); $this->view->transactionForm = $this->transactionForm; $this->view->messages = $this->_flashMessenger->getMessages(); $transaction = new Transaction(); $this->view->transactions = $transaction->byTeam($options); } Next we have the form itself public function setMyPlayers($options) { $data = Doctrine::getTable('Team')->find($options['teamId']); $players = array(); foreach ($data->Players->toArray() as $player) { $players[$player['id']] = "{$player['position']} - {$player['first_name']} {$player['last_name']}"; } $playersSelect = new Zend_Form_Element_Select( 'players', array( 'required' => true, 'label' => 'Players', 'multiOptions' => $players, ) ); $this->addElement($playersSelect); } public function setFreeAgents($options) { $q = Doctrine_Query::create() ->select('CONCAT(p.first_name, " ", p.last_name) as full_name, p.id, p.position') ->from('Player p') ->leftJoin('p.Teams t') ->leftJoin('t.League l ON l.short_name = ?', $options['leagueShortName']) ->where('t.id IS NULL') ->andWhere('p.position = ?', $options['position']) ->orderBy('p.last_name'); $q->setHydrationMode(Doctrine_Core::HYDRATE_ARRAY); $data = $q->execute(); $freeAgents = array(); foreach ($data as $player) { $freeAgents[$player['id']] = $player['full_name']; } $freeAgentsSelect = new Zend_Form_Element_Select( 'freeAgents', array( 'label' => 'Free Agents', 'multiOptions' => $freeAgents, 'size' => 15 ) ); $freeAgentsSelect->setRequired(true); $this->addElement($freeAgentsSelect); } public function setShortLeagueName($options) { $shortLeagueNameHidden = new Zend_Form_Element_Hidden( 'shortLeagueName', array('value' => $options['leagueShortName']) ); $this->addElement($shortLeagueNameHidden); } public function setTeamId($options) { $teamIdHidden = new Zend_Form_Element_Hidden( 'teamId', array('value' => $options['teamId']) ); $this->addElement($teamIdHidden); } There is no init or __construct() method in the form. My problem seems simple enough: reject the form contents as invalid if they have not selected someone from the free agent list. Right now, it sails through as valid. I've spent some considerable time searching online for an answer, and haven't been able to find it. Thanks in advance for any help.
