  • Show a window from 32-bit NPAPI Plugin in 64-bit Safari

    - by Glenn Howes
    I have an old NPAPI plugin for OS X that I'm trying to refit for use with Snow Leopard's version of Safari. My problem is that when I switch Safari to 64-bit mode, it changes the plugin environment to out of process mode (where plugins are hosted by a 32-bit WebKitPluginHost process). And now my toolbar palettes are not visible on screen, even though the NSPanels on which they are based think they are visible. The documentation says that bringing up windows is not recommended, but doesn't say its prohibited; is there something I can do to bring up my Windows?

  • <100% Test coverage - best practices in selecting test areas

    - by Paul Nathan
    Suppose you're working on a project and the time/money budget does not allow 100% coverage of all code/paths. It then follows that some critical subset of your code needs to be tested. Clearly a 'gut-check' approach can be used to test the system, where intuition and manual analysis can produce some sort of test coverage that will be 'ok'. However, I'm presuming that there are best practices/approaches/processes that identify critical elements up to some threshold and let you focus your test elements on those blocks. For example, one popular process for identifying failures in manufacturing is Failure Mode and Effects Analysis. I'm looking for a process(es) to identify critical testing blocks in software.

  • Facebook Developer ToolKit: How should I construct this app?

    - by j0nscalet
    I have created a simple desktop application that I want to use to post status updates for the users of my app. Here's the kicker though that I am having trouble figuring out, the desktop application runs as part of a batch process every night, in which I update the status of certain users. I use the following code to accomplish this: (comes directly from the FDK samples) public FriendViewer() { InitializeComponent(); facebookService1.ApplicationKey = "Key"; facebookService1.Secret = "Secret"; facebookService1.SessionKey = "Session key"; facebookService1.IsDesktopApplication = true; } private void TestService_Load(object sender, EventArgs e) { try { if (!facebookService1.API.users.hasAppPermission(facebook.Types.Enums.Extended_Permissions.status_update)) facebookService1.GetExtendedPermission(facebook.Types.Enums.Extended_Permissions.status_update); if (!facebookService1.API.users.hasAppPermission(facebook.Types.Enums.Extended_Permissions.offline_access)) facebookService1.GetExtendedPermission(facebook.Types.Enums.Extended_Permissions.offline_access); long uid = facebookService1.users.getLoggedInUser(); facebook.Schema.user user = facebookService1.users.getInfo(uid); facebookService1.users.setStatus("Facebook Syndicator rules!"); MessageBox.Show(String.Format("Status set for {0} {1}", user.first_name, user.last_name)); } catch (Exception ex) { MessageBox.Show(ex.Message); Close(); } } My user's day to day activity is done a website front end. Since I dont have any user interaction in a nightly batch process, I cannot use the ConnectToFaceBook method on the FaceBookService to obtain a sessionKey for the user. Ideally I would like to prompt for authorization and extended permissions for my desktop app when a user logins into the web front end then save the sessionKey and uid in the database. At night when my process runs, I would reference the sessionKey and uid in order and update the user's status. I am finding myself fumbling between whether or not my app should be a web or desktop app. Having both a web and desktop app would be confusing to my users, because they would have to grant/manage permissions for both apps. And I looking at this the wrong way? Any help would be greatly appreciated! Thanks.

  • Killing a deadlocked Task in .NET 4 TPL

    - by Dan Bryant
    I'd like to start using the Task Parallel Library, as this is the recommended framework going forward for performing asynchronous operations. One thing I haven't been able to find is any means of forcible Abort, such as what Thread.Abort provides. My particular concern is that I schedule tasks running code that I don't wish to completely trust. In particular, I can't be sure this untrusted code won't deadlock and therefore I can't be certain if a Task I schedule using this code will ever complete. I want to stay away from true AppDomain isolation (due to the overhead and complexity of marshaling), but I also don't want to leave a Task thread hanging around, deadlocked. Is there a way to do this in TPL?

  • TFSBuild.Proj and Manual SQL Server Work Help?

    - by ScSub
    Using the VS 2008 GDR update, I have created a database project. I have created a SQL Server deployment package. I have created a database unit test. Using some wizards, the stuff got into my tfsbuild.proj file so near the end of the automated build process a database is created. I lack a little control of the whole process, I now see. What I would like to do is manually deploy the DB, run 3 custom scripts against the DB, and then manually start the DB unit test. I have other non-DB unit tests that already run. I do not want to use VSMDI or ordered unit test stuff because in out multi-developer environment it gets messy. Help!

  • C# Multithreading File IO (Reading)

    - by washtik
    We have a situation where our application needs to process a series of files and rather than perform this function synchronously, we would like to employ multi-threading to have the workload split amongst different threads. Each item of work is: 1. Open a file for read only 2. Process the data in the file 3. Write the processed data to a Dictionary We would like to perform each file's work on a new thread? Is this possible and should be we better to use the ThreadPool or spawn new threads keeping in mind that each item of "work" only takes 30ms however its possible that hundreds of files will need to be processed. Any ideas to make this more efficient is appreciated.

  • PGP Command Line Decryption --- How to decrypt file?

    - by whitman6732
    I was sent a public key in order to decrypt a pgp-encrypted file. I imported the key with: gpg --import publickey.asc And verified it with gpg --list-keys Now, I'm trying to decrypt the file. I put the passphrase in a file called pass.txt and ran this at the command line: gpg --passphrase-fd ../../pass.txt --decrypt encryptedfile.txt.pgp --output encryptedfile.txt All it says is: Reading passphrase from file descriptor 0 ... And doesn't seem to be doing anything else. I can't tell if it's hanging or not. Is it a relatively quick process? The file is large ( about 2 GB ). Is the syntax for it correct?

  • 301 versus inline rewrites

    - by Kristoffer S Hansen
    I'm in the process of adding 'pretty' URLs to an existing CMS, the menu is auto generated and the new 'pretty' URLs are to be handled independently as a seperate module. The auto-generated menu allways has URLs that look like this index.php?menu_id=n which ofcourse we would like to see as eg. /news or /products I'm currently at the point where I have to decide if I'm going to rewrite all output of the current system or simply put in a hook where I redirect to the 'pretty' URL. To put it differently, should i connect to the database, fetch all 'pretty' URLs, run through the existing output from WYSIWYG's, news modules, forums etc. and do some str_replace or other string manipulation (which I think would be a rather tedious and boring process), or should I simply hook in and throw a 301 redirecting index.php?menu_id=3 to /news will Google (or other search engines) penalize me for having 301's in the menus?

  • py2app prescripts

    - by yoav.aner
    The py2app documentation mentions prescripts, being run by __boot__.py prior to the main python script. I couldn't find a way to easily specify any prescript on the setup.py file or build process. I did however manage to 'hack' __boot__.py manually and add another _run(prescript) command before my main _run(main_script) and it seemed to work fine. It would however be much better using the standard py2app build process. What I'm essentially trying to do is monkey-patch my sites-packages.zip file prior to the main script being launched. The prescript essentially checks for updates on the server, and if there are any, downloads them, and then overwrites the site-packages.zip file. Much quicker than having to re-install the application from scratch. Any ideas?

  • Using PostRequestHandlerExecute, Flush and Close to clean up after a request - why is this bad?

    - by Erwin
    After some requests I need to clean up after the user - by calling a remote web service to release some resources if I guess the user doesn't need them anymore. It is ok to leave them hanging and letting them time out on the other server, but the polite thing to do is to inform it that I do not need them anymore. I do not want to waste the users time waiting for cleaning - so I tried to find place to put it. First I tried Application_EndRequest, but I needed something later. Then I found PostRequestHandlerExecute which seemed like a nice place, but I still need a Flush and Close to release the connection to the user. Protected Sub Application_PostRequestHandlerExecute(ByVal sender As Object, ByVal e As System.EventArgs) Response.Flush() Response.Close() ' Simulation of clean up activity: System.Threading.Thread.Sleep(4000) ' Really a couple of web service calls End Sub Is there some other place I could put these lengthy clean up routines?

  • Keyboard Simulation not working with Keyboard hook for modifier keys

    - by Eduardo Wada
    I have a piece of software that is being used to simulate a certain device on a touchscreen, this device already runs an application that receives keyboard input from the device. My software (reffered to as simulator) displays a virtual keyboard and runs the application. Thus, the simulator sends keys with input simulator: http://inputsimulator.codeplex.com/ And the applciation listens to keys with the following keyboard hook: https://svn.cyberduck.io/tags/release-4-1/source/ch/cyberduck/core/GlobalKeyboardHook.cs My problem is, what some keys from the device's hardware actually do is to sent a key combination (ex: left-alt + 1) to the application and a weird scenario is occurring: The application listens to normal keyboard inputs The simulator sends keys to other applications (ie: visual studio responds to the keys sent when debugging) The simulator can send single keys to the application (I can type) The simulator CANNOT send key combinations to the application (alt+1 is received as just 1 in the application) This started happenning when we imported the application's dll into the same process from the simulator. Could there be any reason why I can't simulate key combinations for a hook in the same process? Is there any easy fix for this?

  • MapViewOfFile shared between 32bit and 64bit processes

    - by MK
    Hi, I'm trying to use MapViewOfFile in a 64 bit process on a file that is already mapped to memory of another 32 bit process. It fails and gives me an "access denied" error. Is this a known Windows limitation or am I doing something wrong? Same code works fine with 2 32bit processes. The code sort of looks like this: hMapFile = OpenFileMapping(FILE_MAP_ALL_ACCESS, FALSE, szShmName); if (NULL == hMapFile) { /* failed to open - create new (this happens in the 32 bit app) */ SECURITY_ATTRIBUTES sa; sa.nLength = sizeof(SECURITY_ATTRIBUTES); sa.bInheritHandle = FALSE; /* give access to members of administrators group */ BOOL success = ConvertStringSecurityDescriptorToSecurityDescriptor( "D:(A;OICI;GA;;;BA)", SDDL_REVISION_1, &(sa.lpSecurityDescriptor), NULL); HANDLE hShmFile = CreateFile(FILE_FAXCOM_SHM, FILE_ALL_ACCESS, 0, &sa, OPEN_ALWAYS, 0, NULL); hMapFile = CreateFileMapping(hShmFile, &sa, PAGE_READWRITE, 0, SHM_SIZE, szShmName); CloseHandle(hShmFile); } // this one fails in 64 bit app pShm = MapViewOfFile(hMapFile, FILE_MAP_ALL_ACCESS, 0, 0, SHM_SIZE);

  • Loading dynamic content and rewrite URL on Hashchange event with Jquery Mobile

    - by user3611500
    I'm building a mobile version for my website using Jquery Mobile API. The framework provides automate AJAX navigation processing. But as far as i know it require "real" pages for loading purpose. What i want to do is override the automate navigation process of it and process the hashchange on my own. But i can't not rewrite the url using window.hashChange, which is running well on my non-mobile website version : $(function () { $(window).off().hashchange(function () { if (location.hash.length > 1) { PageSelect(); } }); $(window).hashchange(); }); I just only want to take advantage on jquery mobile interfaces, i don't want anything with its automate ajax navigation stuff ! I tried to disable it using ajaxEnabled() but got no luck.

  • .NET: IOException for permissions when creating new file?

    - by Rosarch
    I am trying to create a new file and write XML to it: FileStream output = File.Create(Path.Combine(PATH_TO_DATA_DIR, fileName)); The argument evaluates to: C:\path\to\Data\test.xml The exception is: The process cannot access the file 'C:\path\to\Data\test.xml' because it is being used by another process. What am I doing wrong here? UPDATE: This code throws the same exception: StreamWriter writer = new StreamWriter(Path.Combine(PATH_TO_DATA_DIR, fileName)); UPDATE 2: The file I am trying to create does not exist in the file system. So how can be it in use?

  • windbg/cdb hangs when bp hit

    - by aaron
    I have a problem where cdb or windbg hangs frequently, but not all the time, when I'm debugging with it and I attach to a specific application on my machine. I found this article: http://www.nynaeve.net/?p=164 which talks about a symbol loading race condition being the problem, but I can force load the symbols, actually have a breakpoint in-app work, and still have it hang elsewhere. Here is the stack from cdb itself when I attach to it with another debugger: ntdll!NtReadFile kernel32!ReadFile cdb!ReadNonConLine cdb!ConIn cdb!MainLoop cdb!main !analyze reports that APPLICATION_HANG_BusyHang is the problem bucket, and 'ReadNonConLine' is the offending function. as far as the stack goes: ffffffff`fffffffe 00000000`00000000 00000001`3f641498 00000000`0014ea50 : kernel32!ReadFile+0x86 00000000`000002a4 00000000`0014ebb0 00000000`00001000 00000000`00000000 : cdb!ReadNonConLine+0x6d ReadNonConLine has the string "g" at 0014ebb0 passed as a param, which may be part of the command I had at the hanging breakpoint (it was something like bp foo "dt a; g") ReadFile takes a handle as its first parameter. I'm surprised by the value -2, though, that doesn't look valid. Any help is appreciated. Thanks! Aaron

  • what is the best way to generate fake data for classification problem ?

    - by Berkay
    i'm working on a project and i have a subset of user's key-stroke time data.This means that the user makes n attempts and i will use these recorded attempt time data in various kinds of classification algorithms for future user attempts to verify that the login process is done by the user or some another person. (Simply i can say that this is biometrics) I have 3 different times of the user login attempt process, ofcourse this is subset of the infinite data. until now it is an easy classification problem, i decided to use WEKA but as far as i understand i have to create some fake data to feed the classification algorithm. can i use some optimization algorithms ? or is there any way to create this fake data to get min false positives ? Thanks

  • Terminal services and memory limits

    - by Mark Wassell
    Is there a way in Terminal Services to set limits on memory related parameters for a process. For example working set size and, possibly, if it makes sense, total virtual memory allocation for the session? To turn the question around, we have an application which cannot allocate as much virtual memory running on a terminal server as it can when running on a desktop PC (both I would expect to have a limit of 2GB for user mode address space) and I was wondering if there is another limit for processes or users on a terminal server. Perhaps even 2GB per user rather than per process.

  • Scheduling Swingworker threads

    - by Simonw
    Hi, I have a 2 processes to perform in my swing application, one to fill a list, and one to do operations on each element on the list. I've just moved the 2 processes into Swingworker threads to stop the GUI locking up while the tasks are performed, and because I will need to do this set of operations to several lists, so concurrency wouldn't be a bad idea in the first place. However, when I just ran fillList.execute();doStuffToList.execute(); the doStuffToList thread to ran on the empty list (duh...). How do I tell the second process to wait until the first one is done? I suppose I could just nest the second process at the end of the first one, but i dunno, it seems like bad practice.

  • Conditional Validation with Paperclip difficult

    - by Michael Schmitz
    Hi, I have an "item", which goes through a multi-page creation process. Images are uploaded at step five, and I keep track of the steps by using the attribute "complete". When validating whether an image is attached with paperclip, I get problems using the code below: validates_attachment_presence :pic1, :if => Proc.new { |u| u.complete == "step5"} It seems that I can't access the "complete" attribute, as the active-record object seems to be the paperclip image. Is there a way for me to check at which point in the process I am and validate conditionally? Thanks, Michael

  • Java - Difference between SwingWorker and SwingUtilities.invokeLater()

    - by Yatendra Goel
    SwingWorker is used for the following purposes: For running long-running tasks in a different thread so as to prevent the GUI from being unresponsive For updating GUI with the results produced by the long-running task at the end of the task through done() method. For updating GUI from time to time with the intermediate results produced and published by the task with the help of publish() and process() methods. SwingUtilities.invokeLater() can perform the above tasks as follows: Instead of executing SwingWorker.execute() method from the EDT, we can execute ExecutorService.submit(new MyRunnable()) as it will also create another thread which can execute long-running task. For updating GUI at the end of the task, we can put code (written in done() method of case1) SwingUtilites.invokeLater(new RunnableToExecuteDoneMethodCode()) at the end of the task. For updating GUI in the middle of the task, we can put code (written in process() method of case1) SwingUtilites.invokeLater(new RunnableToExecuteProcessMethodCode()) at the place where we called publish() method in case1. I am asking this question because the problem specified in question http://stackoverflow.com/questions/2797483/java-swingworker-can-we-call-one-swingworker-from-other-swingworker-instead-o/2824306#2824306 can be solved by SwingUtilities.invokeLater() but can't be solved with SwingWorker

  • Quartz in Webapplication

    - by JKV
    I have a question in scheduling jobs in web application. If we have to schedule jobs in web application we can either use java util Timer/TimerTask or Quartz(there are also other scheduling mechanism, but I considered Quartz). I was considering which one to use, when i hit the site http://oreilly.com/pub/a/java/archive/quartz.html?page=1 which says using timer has a bad effect as it creates a thread that is out of containers control in the last line. The other pages discuss Quartz and its capabilities, but I can read that Quartz also uses thread and/or threadpool to schedule tasks. My guess is that these threads are also not under the containers control Can anybody clarify this to me Is it safe to use Quartz in my web applications without creating hanging threads or thread locking issues? Thanks in advance
