  • NavigationController pushViewController problems.

    - by Jacek
    Hello. I have created new a view controller in my project (ActivateController). I have added it to the interface of the parent view controller (PrefsViewController): #import <UIKit/UIKit.h> #import "ActivateController.h" @interface PrefsViewController : UIViewController <UITextFieldDelegate> { ActivateController *activateController; } -(IBAction)pressedActivate; @property(nonatomic,retain) IBOutlet ActivateController *activateController; @end I have also added it to parent's controller nib (and changed it type to ActivateController), and connected it to IBOutlet ActivateController. But still, when I perform (on pressedActivate): [self.navigationController pushViewController:activateController animated:YES]; Nothing happens. I have done it successfully many times before. What might be wrong? P.S. pressedActivate is executed for sure (I used NSLog to check).

  • Trying to send email in Java using gmail always results in username and password not accepted.

    - by Thaeos
    When I call the send method (after setting studentAddress), I get this: javax.mail.AuthenticationFailedException: 535-5.7.1 Username and Password not accepted. Learn more at 535 5.7.1 http://mail.google.com/support/bin/answer.py?answer=14257 y15sm906936wfd.10 I'm pretty sure the code is correct, and 100% positive that the username and password details I'm entering are correct. So is this something wrong with gmail or what? This is my code: import java.util.*; import javax.mail.*; import javax.mail.internet.*; public class SendEmail { private String host = "smtp.gmail.com"; private String emailLogin = "[email protected]"; private String pass = "xxx"; private String studentAddress; private String to; private Properties props = System.getProperties(); public SendEmail() { props.put("mail.smtps.auth", "true"); props.put("mail.smtps.starttls.enable", "true"); props.put("mail.smtp.host", host); props.put("mail.smtp.user", emailLogin); props.put("mail.smtp.password", pass); props.put("mail.smtp.port", "587"); to = "[email protected]"; } public void setStudentAddress(String newAddress) { studentAddress = newAddress; } public void send() { Session session = Session.getDefaultInstance(props, null); MimeMessage message = new MimeMessage(session); try { message.setFrom(new InternetAddress(emailLogin)); InternetAddress[] studentAddressList = {new InternetAddress(studentAddress)}; message.setReplyTo(studentAddressList); message.setRecipient(Message.RecipientType.TO, new InternetAddress(to)); message.setSubject("Test Email"); message.setText("This is a test email!"); Transport transport = session.getTransport("smtps"); transport.connect(host, emailLogin, pass); transport.sendMessage(message, message.getAllRecipients()); transport.close(); } catch (MessagingException me) { System.out.println("There has been an email error!"); me.printStackTrace(); } } } Any ideas...

  • Building a Universal iPad App - Where is the device recognition code?

    - by JustinXXVII
    I noticed that when I create a new project in XCode for a Universal iPad/iPhone application, the template comes with two separate App Delegate files, one for each device. I can't seem to locate the place in code where it tries to decide which app delegate to use. I have an existing iPhone project I'd like to port to iPad. My thinking was that if I went ahead and designed the iPad project, I could just import my iPhone classes and nibs, and then use the App Delegate and UIDevice to decide which MainWindow.xib to load. The process went like this: Create an iPad project coded as a split-view create brand new classes and nibs for the iPad import iPhone classes and nibs Change build/target settings in accordance with Universal Apps Use [[UIDevice currentDevice] model] in the AppDelegate to decide which MainWindow to load Will this work, or does the app just automatically know which device it's being deployed on? Thanks for any insight you can offer.

  • How to turn on Mercurial in existing Eclipse project ?

    - by Rabarberski
    I've installed the HgEclipse plugin for Mercurial integration in Eclipse. I have an existing (Java) project in Eclipse, but I can't figure out how to turn on mercurial change tracking for this existing project. It seems I can do an import of a mercurial project (File Import Mercurial Clone ...), but that's only for new Eclipse projects... Of course, I can apply Mercurial via the command line, e.g. hg init in the project directory, but this doesn't get picked up in Eclipse. So, how do I turn on Mercurial for existing Eclipse projects?

  • Maven jaxb2:xjc/jaxws:wsimport to be added in eclipse?

    - by wuntee
    I have a library I am creating based on some WSDL/XSD definitions. I am having a problem having the compiled classes added in the eclipse project. I can see that with a 'mvn compile' that the .class files are generated, as well as the .java files. The problem is that even though the .class files are generated, eclipse is still showing an error on the import statement "import com.whatever.SomeService_Service" that was generated by one of the plugins. I tried forcing the source to go into the project/src/main/java directory, but when the project is cleaned, it deletes files that I have created. Has anyone run into this before/found a way to get it to recognize that the class files are there? Thanks.

  • Cannot format first column in WxPython's ListCtrl

    - by Matt Clarke
    If I set the format of the first column in a ListCtrl to align centre (or align right) nothing happens. It works for the other columns. This only happens on Windows - I have tested it on Linux and it works fine. Does anyone know if there is a work-round or other solution? Here is an example based on code found at http://zetcode.com/wxpython/ import wx import sys packages = [('jessica alba', 'pomona', '1981'), ('sigourney weaver', 'new york', '1949'), ('angelina jolie', 'los angeles', '1975'), ('natalie portman', 'jerusalem', '1981'), ('rachel weiss', 'london', '1971'), ('scarlett johansson', 'new york', '1984' )] class Actresses(wx.Frame): def __init__(self, parent, id, title): wx.Frame.__init__(self, parent, id, title, size=(380, 230)) hbox = wx.BoxSizer(wx.HORIZONTAL) panel = wx.Panel(self, -1) self.list = wx.ListCtrl(panel, -1, style=wx.LC_REPORT) self.list.InsertColumn(0, 'name', wx.LIST_FORMAT_CENTRE,width=140) self.list.InsertColumn(1, 'place', wx.LIST_FORMAT_CENTRE,width=130) self.list.InsertColumn(2, 'year', wx.LIST_FORMAT_CENTRE, 90) for i in packages: index = self.list.InsertStringItem(sys.maxint, i[0]) self.list.SetStringItem(index, 1, i[1]) self.list.SetStringItem(index, 2, i[2]) hbox.Add(self.list, 1, wx.EXPAND) panel.SetSizer(hbox) self.Centre() self.Show(True) app = wx.App() Actresses(None, -1, 'actresses') app.MainLoop()

  • GWT UIBinding cannot find zero-arg constructor

    - by aarestad
    I'm trying my hand at the new GWT 2.0 UIBinder capability, and I have a ui XML that looks like this: <ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder" xmlns:g="urn:import:com.google.gwt.user.client.ui" xmlns:my='urn:import:com.mystuff.mypackage'> <g:VerticalPanel> <!-- other stuff --> <my:FileUploadPanel.ValidatingFileUpload styleName="field" ui:field="fileUpload" /> </g:VerticalPanel> ValidatingFileUpload is a non-static inner class contained in FileUploadPanel. It has an explicit zero-arg constructor that simply calls super(). However, when GWT starts up, I get this error: 00:00:18.359 [ERROR] Rebind result 'com.mystuff.mypackage.FileUploadPanel.ValidatingFileUpload' has no default (zero argument) constructors. java.lang.NoSuchMethodException: com.mystuff.mypackage.FileUploadPanel$ValidatingFileUpload.<init>() Any idea what might be going wrong here?

  • request parameter is taking null value in servlets

    Hi, I want to know how can I get the value of the request parameters "j_username" and "j_password"? After successfully login using form based authentication, I want my servlet to get the value of parameters "j_username" and "j_password", but I'm getting null as the value in both parameters. Could anyone please tell me how can I get the actual value of both paramters?

  • PySide / PyQt QStyledItemDelegate list in table

    - by danodonovan
    Dear All, I'm trying to create a table of lists in Python with Qt (PySide/PyQt - matters not) and my lists are squashed into the table cells. Is there a way to get the list delegates to 'pop out' of their cells? I've attached a simple code snippet - replace 'PySide' with 'PyQt4' depending on your preference from PySide import QtCore, QtGui class ListDelegate(QtGui.QStyledItemDelegate): def createEditor(self, parent, option, index): editor = QtGui.QListWidget(parent) for i in range( 12 ): editor.addItem('list item %d' % i) return editor if __name__ == '__main__': import sys app = QtGui.QApplication(sys.argv) model = QtGui.QStandardItemModel(2, 2) tableView = QtGui.QTableView() delegate = ListDelegate() tableView.setItemDelegate(delegate) tableView.setModel(model) for row in range(2): for column in range(2): item = QtGui.QStandardItem( 'None' ) model.setItem(row, column, item) tableView.setWindowTitle('example') tableView.show() sys.exit(app.exec_()) If you hadn't guessed I'm pretty new to this Qt lark Thanks in advance, Dan

  • Freezing a dual-mode (GUI and console) application using cx_Freeze

    - by Mridang Agarwalla
    Hi, I've developed a Python application that runs both in the GUI mode and the console mode. If any arguments are specified, it runs in a console mode else it runs in the GUI mode. I've managed to freeze this using cx_Freeze. I had some problems hiding the black console window that would pop up with wxPython and so I modified my setup.py script like this: import sys from cx_Freeze import setup, Executable base = None if sys.platform == "win32": base = "Win32GUI" setup( name = "simple_PyQt4", version = "0.1", description = "Sample cx_Freeze PyQt4 script", executables = [Executable("PyQt4app.py", base = base)]) This works fine but now when I try to open up my console and run the executable from there, it doesn't output anything. I don't get any errors or messages so it seems that cx_Feeze is redirecting the stdout somewhere else. Is is possible to get it to work with both mode? Nothing similar to this seems to be documented anywhere. :( Thanks in advance. Mridang

  • How to pass variables using Unittest suite

    - by chrissygormley
    Hello I have test's using unittest. I have a test suite and I am trying to pass variables through into each of the tests. The below code shows the test suite used. class suite(): def suite(self): #Function stores all the modules to be tested modules_to_test = ('testmodule1', 'testmodule2') alltests = unittest.TestSuite() for module in map(__import__, modules_to_test): alltests.addTest(unittest.findTestCases(module)) return alltests It calls tests, I would like to know how to pass variables into the tests from this class. An example test script is below: class TestThis(unittest.TestCase): def runTest(self): assertEqual('1', '1') class TestThisTestSuite(unittest.TestSuite): # Tests to be tested by test suite def makeTestThisTestSuite(): suite = unittest.TestSuite() suite.addTest("TestThis") return suite def suite(): return unittest.makeSuite(TestThis) if __name__ == '__main__': unittest.main() So from the class suite() I would like to enter in a value to change the value that is in assert value. Eg. assertEqual(self.value, '1'). I have tried sys.argv for unittest and it doesn't seem to work. Thanks for any help.

  • Handling button click in ASP.NET MVC 2 RTM

    - by Leniel Macaferi
    I have a View in which the user is able to upload a file to the server. In this view I also have 2 buttons: one to Upload a file and other to Download the last file imported. In my Controller I created 2 action methods: Import and Export. How could I manage to redirect each button click to the proper action method in my Controller? I have tried Html.ActionLink: <%= Html.ActionLink("Upload", "Import", "OracleFile")%> <%= Html.ActionLink("Download", "Export", "OracleFile")%> Html.ActionLink didn't do the trick. The action links were taking me to the right Action methods but they were generating a GET request. This way Request.Files.Count = 0. I need a POST request.

  • Is there a way to automatically make a makefile from a template toolkit template?

    - by Smack my batch up
    My static web pages are built from a huge bunch of templates which are inter-included using Template Toolkit's "import" and "include", so page.html looks like this: [% INCLUDE top %] [% IMPORT middle %] Then top might have even more files included. I have very many of these files, and they have to be run through to create the web pages in various languages (English, French, etc., not computer languages). This is a very complicated process and when one file is updated I would like to be able to automatically remake only the necessary files, using a makefile or something similar. Are there any tools which can parse template toolkit templates and create a dependency list for use in a makefile? Or are there better ways to automate this process?

  • .NET WebService Custom Attribute

    - by DownChapel
    I would like to add a custom attribute to a asmx web service to determine if the request is valid based on the client IP address. This is a similar idea to the AuthorizeAttribute in ASP.NET MVC. Is there anywhere (e.g. a HTTP module) I can put the code to look at the attribute on the webservice and decide whether to allow the request or not? In my web.config the handler for asmx is the ScriptHandlerFactory from the System.Web.Extensions dll. I have already implemented the functionality with a HTTP module and a config file with a list of allowed URLs, but I would prefer to get rid of the config file and just add an attribute to the webservice class. Thanks

  • How to read special characters from stdin in Python?

    - by erickrf
    I'm having trouble reading special characters from stdin. Here are my attempts: import os dir = raw_input("Dir name: ") Dir name: c:/á os.chdir(dir) WindowsError: [Error 2] The system cannot find the file specified: 'c:/\x81\xe1' Ok, so I tried to get the default system encoding and recode the string from stdin: import locale encoding = locale.getdefaultlocale()[1] print encoding cp1252 unicode(dir, encoding) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "c:\Python26\lib\encodings\cp1252.py", line 15, in decode return codecs.charmap_decode(input,errors,decoding_table) UnicodeDecodeError: 'charmap' codec can't decode byte 0x81 in position 3: character maps to <undefined> Now, I don't know how to solve this. Nor can I understand - why is there a problem when I try to access a directory with a name written in the system default encoding itself??

  • Dynamic function docstring

    - by Tom Aldcroft
    I'd like to write a python function that has a dynamically created docstring. In essence for a function func() I want func.__doc__ to be a descriptor that calls a custom __get__ function create the docstring on request. Then help(func) should return the dynamically generated docstring. The context here is to write a python package wrapping a large number of command line tools in an existing analysis package. Each tool becomes a similarly named module function (created via function factory and inserted into the module namespace), with the function documentation and interface arguments dynamically generated via the analysis package.

  • How to properly use .SWC packages in Flash CS 4

    - by DevEight
    Hi! I've googled a lot trying to find how to properly import and use .swc files in Flash CS 4, tried lots of different methods but none seem to work. What I've done is: 1. Placed it in my "D:\Program Files (x86)\Adobe\Adobe Flash CS4\en\Configuration\Components" folder. It does however not show up in the component inspector. 2. Added it in Publishing Settings as a Library and External Library, still can't seem to use it. I've also tried adding "import org.osflash.signals;" after each method but I receive the error "1172: Definition org.osflash:signals could not be found." So what I'm asking for is an easy way to get the .swc package working code-wise with all classes imported etc. The .swc file is as you may have guessed as3signals. Thanks in advance.

  • Can I use some combination of HttpHandler and HttpModule to create an asynchronous file upload?

    - by scottm
    I am trying to write a simple asynchronous file upload control for ASP.Net. I've tried a few implementations out there (AjaxControl Toolkit Async Upload, Telerik RadAsyncUpload, AjaxUploader, Uploadify, etc.), but they all leave me wanting something more. I'd rather not use a Flash component, a simple throbber would be OK. Some don't have client side call backs. I figure you can make an http module that checks the request form's enctype and files collection on BeginRequest and save those files to disk. Then somehow use an httpHandler to poll the module's status but I can't quite figure out how to put it all together asynchronously. Can you help me arrange the pieces?
