  • Create Zip File In Windows and Extract Zip File In Linux

    - by Yan Cheng CHEOK
    I had created a zip file (together with directory) under Windows as follow : package sandbox; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.IOException; import java.util.zip.ZipEntry; import java.util.zip.ZipOutputStream; /** * * @author yan-cheng.cheok */ public class Main { /** * @param args the command line arguments */ public static void main(String[] args) { // These are the files to include in the ZIP file String[] filenames = new String[]{"MyDirectory" + File.separator + "MyFile.txt"}; // Create a buffer for reading the files byte[] buf = new byte[1024]; try { // Create the ZIP file String outFilename = "outfile.zip"; ZipOutputStream out = new ZipOutputStream(new FileOutputStream(outFilename)); // Compress the files for (int i=0; i<filenames.length; i++) { FileInputStream in = new FileInputStream(filenames[i]); // Add ZIP entry to output stream. out.putNextEntry(new ZipEntry(filenames[i])); // Transfer bytes from the file to the ZIP file int len; while ((len = in.read(buf)) > 0) { out.write(buf, 0, len); } // Complete the entry out.closeEntry(); in.close(); } // Complete the ZIP file out.close(); } catch (IOException e) { e.printStackTrace(); } } } The newly created zip file can be extracted without problem under Windows, by using http://www.exampledepot.com/egs/java.util.zip/GetZip.html However, I realize if I extract the newly created zip file under Linux, using http://www.exampledepot.com/egs/java.util.zip/GetZip.html, I will get a file named "MyDirectory\MyFile.txt" instead of MyFile.txt being placed under folder MyDirectory. I try to solve the problem by changing the zip file creation code to String[] filenames = new String[]{"MyDirectory" + "/" + "MyFile.txt"}; But, is this an eligible solution, by hard-coded the seperator? Will it work under Mac OS? (I do not have a Mac to try out)

  • GDI RoundRect on Compact Framework: make rounded rectangle's outside transparent.

    - by VansFannel
    Hello! I'm using the RoundRect GDI function to draw a rounded rectangle following this example: .NET CF Custom Control: RoundedGroupBox Because all controls are square, it also draw the corners outside of the rounded rectangle. How can I make this space left outside the rectangle transparent? The OnPaint method is: protected override void OnPaint(PaintEventArgs e) { int outerBrushColor = HelperMethods.ColorToWin32(m_outerColor); int innerBrushColor = HelperMethods.ColorToWin32(this.BackColor); IntPtr hdc = e.Graphics.GetHdc(); try { IntPtr hbrOuter = NativeMethods.CreateSolidBrush(outerBrushColor); IntPtr hOldBrush = NativeMethods.SelectObject(hdc, hbrOuter); NativeMethods.RoundRect(hdc, 0, 0, this.Width, this.Height, m_diametro, m_diametro); IntPtr hbrInner = NativeMethods.CreateSolidBrush(innerBrushColor); NativeMethods.SelectObject(hdc, hbrInner); NativeMethods.RoundRect(hdc, 0, 18, this.Width, this.Height, m_diametro, m_diametro); NativeMethods.SelectObject(hdc, hOldBrush); NativeMethods.DeleteObject(hbrOuter); NativeMethods.DeleteObject(hbrInner); } finally { e.Graphics.ReleaseHdc(hdc); } if (!string.IsNullOrEmpty(m_roundedGroupBoxText)) { Font titleFont = new Font("Tahoma", 9.0F, FontStyle.Bold); Brush titleBrush = new SolidBrush(this.BackColor); try { e.Graphics.DrawString(m_roundedGroupBoxText, titleFont, titleBrush, 14.0F, 2.0F); } finally { titleFont.Dispose(); titleBrush.Dispose(); } } base.OnPaint(e); } An the OnPaintBackground is: protected override void OnPaintBackground(PaintEventArgs e) { if (this.Parent != null) { SolidBrush backBrush = new SolidBrush(this.Parent.BackColor); try { e.Graphics.FillRectangle(backBrush, 0, 0, this.Width, this.Height); } finally { backBrush.Dispose(); } } } Thank you!

  • How to clean-up an Entity Framework object context?

    - by Daniel Brückner
    I am adding several entities to an object context. try { forach (var document in documents) { this.Validate(document); // May throw a ValidationException. this.objectContext.AddToDocuments(document); } this.objectContext.SaveChanges(); } catch { // How to clean-up the object context here? throw; } If some of the documents pass the the validation and one fails, all documents that passed the validation remain added to the object context. I have to clean-up the object context because it may be reused and the following can happen. var documentA = new Document { Id = 1, Data = "ValidData" }; var documentB = new Document { Id = 2, Data = "InvalidData" }; var documentC = new Document { Id = 3, Data = "ValidData" }; try { // Adding document B will cause a ValidationException but only // after document A is added to the object context. this.DocumentStore.AddDocuments(new[] { documentA, documentB, documentC }); } catch (ValidationException) { } // Try again without the invalid document B. this.DocumentStore.AddDocuments(new[] { documentA, documentC }); This will again add document A to the object context and in consequence SaveChanges() will throw an exception because of a duplicate primary key. So I have to remove all already added documents in the case of an validation error. I could of course perform the validation first and only add all documents after they have been successfully validated. But sadly this does not solve the whole problem - if SaveChanges() fails all documents still remain add but unsaved. I tried to detach all objects returned by this.objectContext.ObjectStateManager.GetObjectStateEntries(EntityState.Added) but I am getting a exception stating that the object is not attached. So how do I get rid of all added but unsaved objects?

  • android app working on simulator but not on phone

    - by raqz
    i have this app that i developed and it works great on the simulator with no errors what so ever. but the moment i try to run the same on the phone for testing, the app crashes stating filenotfoundexception. it says the file /res/drawable/divider_horizontal.9.png is missing. but actually speaking, i have never referenced that file through my code. i believe its a system/os file that is unavailable. i have a custom list view, i guess its the divider there... could somebody please suggest what is wrong here. i believe this is a similar issue discussed here..but i am unable to make

  • C# XMLRPC Multi Threaded newPost something is not right

    - by user1047463
    I recently decided to get my feet wet with c# multi threading and my progress was good until now. My program uses XML-RPC to create new posts on wordpress. When I run my app on the localhost everything works fine and i successfully able to create new posts on wordpress using a multi threaded approach. However when I try to do the same with a wordpress installed on a remote server , new posts won't appear, so when i go to see all posts, the total number of posts remains unchanged. Another thing to note is the function that creates a new post does return the ID of a supposedly created posts. But as I mentioned previously the new posts are not visible when I try to access them in admin menu. Since I'm new to the multithreading I was hoping some of you guys can help me and check if I'm doing anything wrong. Heres the code that creates threads and calls create post function. foreach (DataRow row in dt.Rows) { Thread t = null; t = new Thread(createPost); lock (t) { t.Start(); } } public void createPost() { string postid; try { icp = (IcreatePost)XmlRpcProxyGen.Create(typeof(IcreatePost)); clientProtocol = (XmlRpcClientProtocol)icp; clientProtocol.Url = xmlRpcUrl; postid = icp.NewPost(1, blogLogin, blogPass, newBlogPost, 1); currentThread--; threadCountLabel.Invoke(new MethodInvoker(delegate { threadCountLabel.Text = currentThread.ToString(); })); } catch (Exception ex) { MessageBox.Show( createPost ERROR ->" + ex.Message); } }

  • Clipboard Copy-Paste doesn't work on Win Server 2008/Vista 64bit

    - by Itay Levin
    Hi, I am trying to use Clipboard API (in Delphi) to extract images from Word documents. my code works OK in Windows XP/2003 but in windows 2008 64 bit it doesn't work. in win 2008 i get an error saying that Clipboard.Formats is empty and doesn't contain any format. The image seems to be copied to the Clipboard (i can see it in the clipboard via Word) but when i try to ask the clipboard what format does he have it said it doesn't have any formats. how can i access the clipboard programmatically on win 2008/Vista? from what i know of 2008 64 bit, it might be a security issue... here is the code snippet: This is how i am trying to copy the Image to the clipboard: W.ActiveDocument.InlineShapes.Item(1).Select; // W is a word ole object W.Selection.Copy; and this is how i try to paste it. Clipboard.Open; Write2DebugFile('FormatCount = ' + IntToStr(Clipboard.FormatCount)); // FormatCount=0 For JJ := 1 to Clipboard.FormatCount Do Write2DebugFile('#'+ IntToStr(JJ) + ':' + IntToStr(Clipboard.Formats[JJ])); If (Clipboard.HasFormat(CF_BITMAP)) or (Clipboard.HasFormat(CF_PICTURE)) or (Clipboard.HasFormat(CF_METAFILEPICT)) then // all HasFormat calls returns false. Begin Jpeg := TJPEGImage.Create; Bitmap := TBitmap.Create; Bitmap.LoadFromClipboardFormat(cf_BitMap,ClipBoard.GetAsHandle(cf_Bitmap),0); Jpeg.Assign(Bitmap); Jpeg.SaveToFile(JpgFileN); try Jpeg.Free; except; end; ResizeImage(JpgFileN,750); Write2DebugFile('Saving ' + JpgFileN); End else Write2DebugFile('Doesnt have the right format'); Thanks in advance, Itay

  • Django: Using 2 different AdminSite instances with different models registered

    - by omat
    Apart from the usual admin, I want to create a limited admin for non-staff users. This admin site will have different registered ModelAdmins. I created a folder /useradmin/ in my project directory and similar to contrib/admin/_init_.py I added an autodiscover() which will register models defined in useradmin.py modules instead of admin.py: # useradmin/__init__.py def autodiscover(): # Same as admin.autodiscover() but registers useradmin.py modules ... for app in settings.INSTALLED_APPS: mod = import_module(app) try: before_import_registry = copy.copy(site._registry) import_module('%s.useradmin' % app) except: site._registry = before_import_registry if module_has_submodule(mod, 'useradmin'): raise I also cretated sites.py under useradmin/ to override AdminSite similar to contrib/admin/sites: # useradmin/sites.py class UserAdminSite(AdminSite): def has_permission(self, request): # Don't care if the user is staff return request.user.is_active def login(self, request): # Do the login stuff but don't care if the user is staff if request.user.is_authenticated(): ... else: ... site = UserAdminSite(name='useradmin') In the project's URLs: # urls.py from django.contrib import admin import useradmin admin.autodiscover() useradmin.autodiscover() urlpatterns = patterns('', (r'^admin/', include(admin.site.urls)), (r'^useradmin/', include(useradmin.site.urls)), ) And I try to register different models in admin.py and useradmin.py modules under app directories: # products/useradmin.py import useradmin class ProductAdmin(useradmin.ModelAdmin): pass useradmin.site.register(Product, ProductAdmin) But when registering models in useradmin.py like useradmin.site.register(Product, ProductAdmin), I get 'module' object has no attribute 'ModelAdmin' exception. Though when I try this via shell; import useradmin from useradmin import ModelAdmin does not raise any exception. Any ideas what might be wrong? Edit: I tried going the @Luke way and arranged the code as follows as minimal as possible: (file paths are relative to the project root) # admin.py from django.contrib.admin import autodiscover from django.contrib.admin.sites import AdminSite user_site = AdminSite(name='useradmin') # urls.py (does not even have url patterns; just calls autodiscover()) import admin admin.autodiscover() # products/admin.py import admin from products.models import Product admin.user_site.register(Product) As a result I get an AttributeError: 'module' object has no attribute 'user_site' when admin.user_site.register(Product) in products/admin.py is called. Any ideas? Solution: I don't know if there are better ways but, renaming the admin.py in the project root to useradmin.py and updating the imports accordingly resolved the last case, which was a naming and import conflict.

    I am using the following code: private WSHttpBinding ws; private EndpointAddress Srv_Login_EndPoint; private ChannelFactory<Srv_Login.Srv_ILogin> Srv_LoginChannelFactory; private Srv_Login.Srv_ILogin LoginService; The Login is my constructor: public Login() { InitializeComponent(); ws = new WSHttpBinding(); Srv_Login_EndPoint = new EndpointAddress("http://localhost:2687/Srv_Login.svc"); Srv_LoginChannelFactory = new ChannelFactory<Srv_Login.Srv_ILogin>(ws, Srv_Login_EndPoint); } And I'm using service this way: private void btnEnter_Click(object sender, EventArgs e) { try { LoginService = Srv_LoginChannelFactory.CreateChannel(); Srv_Login.LoginResult res = new Srv_Login.LoginResult(); res = LoginService.IsAuthenticated(txtUserName.Text.Trim(), txtPassword.Text.Trim()); if (res.Status == true) { int Id = int.Parse(res.Result.ToString()); } else { lblMessage.Text = "Not Enter"; } } catch (Exception ex) { MessageBox.Show(ex.Message); } finally { Srv_LoginChannelFactory.Close(); } } When the user enters a valid username and password, everything is fine. When the user enters a wrong username and password, the first try correctly displays a "Not Enter" message, but on the second try, the user sees this message: {System.ObjectDisposedException: Cannot access a disposed object. Object name: 'System.ServiceModel.ChannelFactory`1[Test_Poosesh.Srv_Login.Srv_ILogin]'. at System.ServiceModel.Channels.CommunicationObject.ThrowIfDisposed() at System.ServiceModel.ChannelFactory.EnsureOpened() at System.ServiceModel.ChannelFactory`1.CreateChannel(EndpointAddress address, Uri via) at System.ServiceModel.ChannelFactory`1.CreateChannel() How can I fix my code to prevent this error from occurring?

  • ThreadAbortException (WebClient using DownloadFile to grab file from server)

    - by baron
    Hi Everyone, Referencing my Earlier Question, regarding downloading a file from a server and handling exceptions properly. I am positive that I had this solved, then in classic programming fashion, returned days later to frustratingly find it broken :-( Updated code: private static void GoGetIt(HttpContext context) { var directoryInfoOfWhereTheDirectoryFullOfFilesShouldBe = new FileInfo(......); var name = SomeBasicLogicToDecideName(); //if (!directoryInfoOfWhereTheDirectoryFullOfFilesShouldBe.RefreshExists()) //{ // throw new Exception(string.Format("Could not find {0}.", name)); //} var tempDirectory = ""; //Omitted - creates temporary directory try { directoryInfoOfWhereTheDirectoryFullOfFilesShouldBe.CopyAll(tempDirectory); var response = context.Response; response.ContentType = "binary/octet-stream"; response.AddHeader("Content-Disposition", string.Format("attachment;filename={0}.zip", name)); ZipHelper.ZipDirectoryToStream(tempDirectory, response.OutputStream); response.End(); } catch (Exception ex) { Debug.WriteLine(ex.ToString()); context.Response.StatusCode = 404; } finally { tempDirectory.DeleteWithPrejudice(); } } This was working fine, and returning the zip, otherwise if the file didn't exist returning 404. Then on the client side I could handle this: public bool Download() { try { using (var client = new WebClient()) { client.DownloadFile(name, tempFilePath); } } catch (Exception) { fileExists = false; } return fileExists; } But the problem now is two things. 1) I get System.Threading.ThreadAbortException: Thread was being aborted in the server side try-catch block. Usually this was just a file not found exception. I have no idea what or why that new exception is throwing? 2) Now that a different exception is throwing on the server side instead of the file not found, it would seem I can't use this set up for the application, because back on client side, any exception is assumed to be filenotfound. Any help, especially info on why this ThreadAbortException is throwing!?!? greatly appreciated. Cheers

  • C# - WinForms - Exception Handling for Events

    - by JustLooking
    Hi all, I apologize if this is a simple question (my Google-Fu may be bad today). Imagine this WinForms application, that has this type of design: Main application - shows one dialog - that 1st dialog can show another dialog. Both of the dialogs have OK/Cancel buttons (data entry). I'm trying to figure out some type of global exception handling, along the lines of Application.ThreadException. What I mean is: Each of the dialogs will have a few event handlers. The 2nd dialog may have: private void ComboBox_SelectedIndexChanged(object sender, EventArgs e) { try { AllSelectedIndexChangedCodeInThisFunction(); } catch(Exception ex) { btnOK.enabled = false; // Bad things, let's not let them save // log stuff, and other good things } } Really, all the event handlers in this dialog should be handled in this way. It's an exceptional-case, so I just want to log all the pertinent information, show a message, and disable the okay button for that dialog. But, I want to avoid a try/catch in each event handler (if I could). A draw-back of all these try/catch's is this: private void someFunction() { // If an exception occurs in SelectedIndexChanged, // it doesn't propagate to this function combobox.selectedIndex = 3; } I don't believe that Application.ThreadException is a solution, because I don't want the exception to fall all the way-back to the 1st dialog and then the main app. I don't want to close the app down, I just want to log it, display a message, and let them cancel out of the dialog. They can decide what to do from there (maybe go somewhere else in the app). Basically, a "global handler" in between the 1st dialog and the 2nd (and then, I suppose, another "global handler" in between the main app and the 1st dialog). Thanks.

  • Invoking ADO.NET from MATLAB

    - by Andrew Shepherd
    It's possible to call .NET from MATLAB, so I thought I would try to use ADO.NET to connect to a database. I seem to have hit a blocking problem - anytime you try and create a Command object, it throws an error. You can try this yourself: >> NET.addAssembly('System.Data'); >> sqlconn = System.Data.SqlClient.SqlConnection(); >> sqlconn.State ans = Closed >> % So far, so good >> sqlcmd = System.Data.SqlClient.SqlCommand(); ??? Error using ==> System.Data.SqlClient.SqlCommand 'Connection' is already defined as a property. >> Does anyone have some insight into this? It seems like a pure and simple bug on MATLAB's part - maybe it happens with every .NET class that happens to have a property called "Connection". Should I just throw in the towel and give up on using MATLAB to talk to a database using .NET?

  • Zend Framework: How to start PHPUnit testing Forms?

    - by Andrew
    I am having trouble getting my filters/validators to work correctly on my form, so I want to create a Unit test to verify that the data I am submitting to my form is being filtered and validated correctly. I started by auto-generating a PHPUnit test in Zend Studio, which gives me this: <?php require_once 'PHPUnit/Framework/TestCase.php'; /** * Form_Event test case. */ class Form_EventTest extends PHPUnit_Framework_TestCase { /** * @var Form_Event */ private $Form_Event; /** * Prepares the environment before running a test. */ protected function setUp () { parent::setUp(); // TODO Auto-generated Form_EventTest::setUp() $this->Form_Event = new Form_Event(/* parameters */); } /** * Cleans up the environment after running a test. */ protected function tearDown () { // TODO Auto-generated Form_EventTest::tearDown() $this->Form_Event = null; parent::tearDown(); } /** * Constructs the test case. */ public function __construct () { // TODO Auto-generated constructor } /** * Tests Form_Event->init() */ public function testInit () { // TODO Auto-generated Form_EventTest->testInit() $this->markTestIncomplete( "init test not implemented"); $this->Form_Event->init(/* parameters */); } /** * Tests Form_Event->getFormattedMessages() */ public function testGetFormattedMessages () { // TODO Auto-generated Form_EventTest->testGetFormattedMessages() $this->markTestIncomplete( "getFormattedMessages test not implemented"); $this->Form_Event->getFormattedMessages(/* parameters */); } } so then I open up terminal, navigate to the directory, and try to run the test: $ cd my_app/tests/unit/application/forms $ phpunit EventTest.php Fatal error: Class 'Form_Event' not found in .../tests/unit/application/forms/EventTest.php on line 19 So then I add a require_once at the top to include my Form class and try it again. Now it says it can't find another class. I include that one and try it again. Then it says it can't find another class, and another class, and so on. I have all of these dependencies on all these other Zend_Form classes. What should I do? How should I go about testing my Form to make sure my Validators and Filters are being attached correctly, and that it's doing what I expect it to do. Or am I thinking about this the wrong way?

  • AVAudioPlayer only initializes with some files

    - by Brendan
    Hi everyone, I'm having trouble playing some files with AVAudioPlayer. When I try to play a certain m4a, it works fine. It also works with an mp3 that I try. However it fails on one particular mp3 every time (15 Step, by Radiohead), regardless of the order in which I try to play them. The audio just does not play, though the view loading and everything that happens concurrently happens correctly. The code is below. I get the "Player loaded." log output on the other two songs, but not on 15 Step. I know the file path is correct (I have it log outputted earlier in the app, and it is correct). Any ideas? NSData *musicData = [NSData dataWithContentsOfURL:[[NSURL alloc] initFileURLWithPath:[[NSBundle mainBundle] pathForResource:[song filename] ofType:nil]]]; NSLog([[NSBundle mainBundle] pathForResource:[song filename] ofType:nil]); if(musicData) { NSLog(@"File found."); } self.songView.player = [[AVAudioPlayer alloc] initWithData:musicData error:nil]; if(self.songView.player) { NSLog(@"Player loaded."); } [self.songView.player play]; NSLog(@"You should be hearing something now."); Thanks, Brendan

  • Java synchronized seems ignored

    - by viraptor
    Hi, I've got the following code, which I expected to deadlock after printing out "Main: pre-sync". But it looks like synchronized doesn't do what I expect it to. What happens here? import java.util.*; public class deadtest { public static class waiter implements Runnable { Object obj; public waiter(Object obj) { this.obj = obj; } public void run() { System.err.println("Thead: pre-sync"); synchronized(obj) { System.err.println("Thead: pre-wait"); try { obj.wait(); } catch (Exception e) { } System.err.println("Thead: post-wait"); } System.err.println("Thead: post-sync"); } } public static void main(String args[]) { Object obj = new Object(); System.err.println("Main: pre-spawn"); Thread waiterThread = new Thread(new waiter(obj)); waiterThread.start(); try { Thread.sleep(1000); } catch (Exception e) { } System.err.println("Main: pre-sync"); synchronized(obj) { System.err.println("Main: pre-notify"); obj.notify(); System.err.println("Main: post-notify"); } System.err.println("Main: post-sync"); try { waiterThread.join(); } catch (Exception e) { } } } Since both threads synchronize on the created object, I expected the threads to actually block each other. Currently, the code happily notifies the other thread, joins and exits.

  • Apache Axis2 1.5.1 and NTLM Authentication

    - by arcticpenguin
    I've browsed all of the discussions here on StackOverflow regarding NTLM and Java, and I can't seem to find the answer. I'll try and be much more specific. Here's some code that returns a client stub that (I hope) is configured for NTLM authentication: ServiceStub getService() { try { ServiceStub stub = new ServiceStub( "http://myserver/some/path/to/webservices.asmx"); // this service is hosted on IIS List<String> ntlmPreferences = new ArrayList<String>(1); ntlmPreferences.add(HttpTransportProperties.Authenticator.NTLM); HttpTransportProperties.Authenticator ntlmAuthenticator = new HttpTransportProperties.Authenticator(); ntlmAuthenticator.setPreemptiveAuthentication(true); ntlmAuthenticator.setAuthSchemes(ntlmPreferences); ntlmAuthenticator.setUsername("me"); ntlmAuthenticator.setHost("localhost"); ntlmAuthenticator.setDomain("mydomain"); Options options = stub._getServiceClient().getOptions(); options.setProperty(HTTPConstants.AUTHENTICATE, ntlmAuthenticator); options.setProperty(HTTPConstants.REUSE_HTTP_CLIENT, "true"); stub._getServiceClient().setOptions(options); return stub; } catch (AxisFault e) { e.printStackTrace(); } return null; } This returns a valid SerivceStub object. When I try to invoke a call on the stub, I see the following in my log: Jun 9, 2010 12:12:22 PM org.apache.commons.httpclient.auth.AuthChallengeProcessor selectAuthScheme INFO: NTLM authentication scheme selected Jun 9, 2010 12:12:22 PM org.apache.commons.httpclient.HttpMethodDirector authenticate SEVERE: Credentials cannot be used for NTLM authentication: org.apache.commons.httpclient.UsernamePasswordCredentials Does anyone have a solution to this issue?

  • GHC 6.12 and MacPorts

    - by absz
    I recently installed GHC 6.12 and the Haskell Platform 2010.1.0.1 on my Intel MacBook running OS X 10.5.8, and initially, everything worked fine. However, I discovered that if I use cabal install to install a package which depends on a MacPorts library (e.g., cabal install --extra-lib-dirs=/opt/local/lib --extra-include-dirs=/opt/local/include gd), things work fine in GHCi, but if I try to compile, I get the error Linking test ... Undefined symbols: "_iconv_close", referenced from: _hs_iconv_close in libHSbase-4.2.0.0.a(iconv.o) "_iconv", referenced from: _hs_iconv in libHSbase-4.2.0.0.a(iconv.o) "_iconv_open", referenced from: _hs_iconv_open in libHSbase-4.2.0.0.a(iconv.o) ld: symbol(s) not found collect2: ld returned 1 exit status After some Googling, I found a long Haskell-cafe thread discussing this problem. The upshot seems to be that MacPorts installs an updated version of libiconv, and the binary interface is slightly different from the version included with the system. Consequently, if you try to link with any MacPorts library, the MacPorts libiconv gets linked in too; and since the base library was built to link against a different version of libiconv, things break. I've tried setting LD_LIBRARY_PATH and DYLD_LIBRARY_PATH and adding more flags to try to get it to look at /usr/lib again (e.g. cabal install --extra-lib-dirs=/opt/local/lib --extra-include-dirs=/opt/local/include --extra-lib-dirs=/usr/lib --extra-include-dirs=/usr/include gd), but neither worked. Uninstalling the MacPorts libiconv isn't really an option, since I have a bunch of ports installed which depend on it---including some ports I want Haskell to link to, like gd2. From what I've seen online, the upshot really seems to be "you're boned": you cannot link against any MacPorts library while compiling with GHC, and there doesn't seem to be a solution. However, that thread was from the end of 2009, so I figure there's a chance that someone has a solution, workaround, ridiculous hack… anything, really. So: does anybody know how to get GHC 6.12 to link against the system libiconv at the same time as it links to libraries from MacPorts? Or, failing that, a way to make linking not break in some other clever way?

  • Are Django template tags cached?

    - by thebossman
    I have gone through the (painful) process of writing a custom template tag for use in Django. It is registered as an inclusion_tag so that it renders a template. However, this tag breaks as soon as I try to change something. I've tried changing the number of parameters and correspondingly changing the parameters when it's called. It's clear the new tag code isn't being loaded, because an error is thrown stating that there is a mismatch in the number of parameters, and it's evident that it's attempting to call the old function. The same problem occurs if I try to change the name of the template being rendered and correspondingly change the name of the template on disk. It continues to try to call the old template. I've tried clearing old .pyc files with no luck. Overall, the system is acting as though it's caching the template tags, likely due to the register command. I have dug through endless threads trying to find out if this is so, but all could find it James Bennett stating here that register doesn't do anything. Please help!

  • object_getInstanceVariable works for float, int, bool, but not for double?

    - by Russel West
    I've got object_getInstanceVariable to work as here however it seems to only work for floats, bools and ints not doubles. I do suspect I'm doing something wrong but I've been going in circles with this. float myFloatValue; float someFloat = 2.123f; object_getInstanceVariable(self, "someFloat", (void*)&myFloatValue); works, and myFloatValue = 2.123 but when I try double myDoubleValue; double someDouble = 2.123f; object_getInstanceVariable(self, "someDouble", (void*)&myDoubleValue); i get myDoubleValue = 0. If I try to set myDoubleValue before the function eg. double myDoubleValue = 1.2f, the value is unchanged when I read it after the object_getInstanceVariable call. setting myIntValue to some other value before the getinstancevar function above returns 2 as it should, ie. it has been changed. then I tried Ivar tmpIvar = object_getInstanceVariable(self, "someDouble", (void*)&myDoubleValue); if i do ivar_getName(tmpIvar) i get "someDouble", but myDoubuleValue = 0 still! then i try ivar_getTypeEncoding(tmpIvar) and i get "d" as it should be. So to summarize, if typeEncoding = float, it works, if it is a double, the result is not set but it correctly reads the variable and the return value (Ivar) is also correct. I must be doing something basic wrong that I cant see so I'd appreciate if someone could point it out.

  • How do I check if output stream of a socket is closed?

    - by Roman
    I have this code: public void post(String message) { output.close(); final String mess = message; (new Thread() { public void run() { while (true) { try { output.println(mess); System.out.println("The following message was successfully sent:"); System.out.println(mess); break; } catch (NullPointerException e) { try {Thread.sleep(1000);} catch (InterruptedException ie) {} } } } }).start(); } As you can see I close the socket in the very beginning of the code and then try to use it to send some information to another computer. The program writes me "The following message was successfully sent". It means that the NullPointerException was not thrown. So, does Java throw no exception if it tries to use a closed output stream of a socket? Is there a way to check if a socket is closed or opened? ADDED I initialize the socket in the following way: clientSideSocket = new Socket(hostname,port); PrintWriter out = new PrintWriter(clientSideSocket.getOutputStream(), true); browser.output = out;

    - by Sho Minamimoto
    Hey, first time post, I'm really stuck on httplib2. I've been reading up on it from diveintopython3.org, but it mentions nothing about a timeout function. I look up the documentation, but the only thing I see is an ability to put a timeout int but there are no units specified (seconds? milliseconds? What's the default if None?) This is what I have (I also have code to check what the response is and try again, but it's never tried more than once) h = httplib2.Http('.cache', timeout=None) for url in list: response, content = h.request(url) more stuff... So the Http object stays around until some arbitrary time, but I'm downloading a ton of pages from the same server, and after a while, it hangs on getting a page. No errors are thrown, the thing just hangs at a page. So then I try: h = httplib2.Http('.cache', timeout=None) for url in list: try: response, content = h.request(url) except: h = httplib2.Http('.cache', timeout=None) more stuff... But then it recreates another Http object every time (goes down the 'except' path)...I dont understand how to keep getting with the same object, until it expires and I make another. Also, is there a way to set a timeout on an individual request? Thanks for the help!

  • How to change identifier quote character in SSIS for connection to ODBC DSN

    - by William Rose
    I'm trying to create an SSIS 2008 Data Source View that reads from an Ingres database via the ODBC driver for Ingres. I've downloaded the Ingres 10 Community Edition to get the ODBC driver, installed it, set up the data access server and a DSN on the server running SSIS. If I connect to the SQL Server 2008 Database Engine on the server running SSIS, I can retrieve data from Ingres over the ODBC DSN by running the following command: SELECT * FROM OPENROWSET( 'MSDASQL' , 'DSN=IngresODBC;UID=testuser;PWD=testpass' , 'SELECT * FROM iitables') So I am quite sure that the ODBC setup is correct. If I try the same query with SQL Server style bracketed identifier quotes, I get an error, as Ingres doesn't support this syntax. SELECT * FROM OPENROWSET( 'MSDASQL' , 'DSN=IngresODBC;UID=testuser;PWD=testpass' , 'SELECT * FROM [iitables]') The error is "[Ingres][Ingres 10.0 ODBC Driver][Ingres 10.0]line 1, Unexpected character '['.". What I am finding is that I get the same error when I try to add tables from Ingres to an SSIS Data Source View. The initial step of selecting the ODBC Provider works fine, and I am shown a list of tables / views to add. I then select any table, and try to add it to the view, and get "ERROR [5000A] [Ingres][Ingres 10.0 ODBC Driver][Ingres 10.0]line 3, Unexpected character '['.". Following Ed Harper's suggestion of creating a named query also seems to be stymied. If I put into my named query the following text: SELECT * FROM "iitables" I still get an error: "ERROR [5000A] [Ingres][Ingres 10.0 ODBC Driver][Ingres 10.0]line 2, Unexpected character '['". According to the error, the query text passed by SSIS to ODBC was: SELECT [iitables].* FROM ( SELECT * FROM "iitables" ) AS [iitables] It seems that SSIS assumes that bracket quote characters are acceptable, when they aren't. How can I persuade it not to use them? Double quotes are acceptable.

  • RMI no such object in table, Server communication error

    - by ben-casey
    My goal is to create a Distributed computing program that launches a server and client at the same time. I need it to be able to install on a couple of machines and have all the machines communicating with each other, i.e. Master node and 5 slave nodes all from one application. My problem is that I cannot properly use unicastRef, I'm thinking that it is a problem with launching everything on the same port, is there a better way I am overlooking? this is part of my code (the part that matters) try { RMIServer obj = new RMIServer(); obj.start(5225); } catch (Exception e) { e.printStackTrace(); } try { System.out.println("We are slave's "); Registry rr = LocateRegistry.getRegistry("127.0.0.1", Store.PORT, new RClient()); Call ss = (Call) rr.lookup("FILLER"); System.out.println(ss.getHello()); } catch (Exception e) { e.printStackTrace(); } } this is my main class (above) this is the server class (below) public RMIServer() { } public void start(int port) throws Exception { try { Registry registry = LocateRegistry.createRegistry(port, new RClient(), new RServer()); Call stuff = new Call(); registry.bind("FILLER", stuff); System.out.println("Server ready"); } catch (Exception e) { System.err.println("Server exception: " + e.toString()); e.printStackTrace(); } } I don't know what I am missing or what I am overlooking but the output looks like this. Listen on 5225 Listen on 8776 Server ready We are slave's Listen on 8776 java.rmi.NoSuchObjectException: no such object in table at sun.rmi.transport.StreamRemoteCall.exceptionReceivedFromServer(StreamRemoteCall.java:255) at sun.rmi.transport.StreamRemoteCall.executeCall(StreamRemoteCall.java:233) at sun.rmi.server.UnicastRef.invoke(UnicastRef.java:359) at sun.rmi.registry.RegistryImpl_Stub.lookup(Unknown Source) at Main.main(Main.java:62) line 62 is this ::: Call ss = (Call) rr.lookup("FILLER");
