  • How to display static (shared) object's properties in a PropertyGrid?

    - by Paul Sasik
    I would like to display static (shared) objects at runtime in a PropertyGrid but if I try to set the selected object property of the grid like this: _propertyGrid.SelectedObject = System.Windows.Forms.Application I get a compilation error: 'Application' is a type and cannot be used as an expression. Is there a way to display a static (shared) object or the object's properties in the PropertyGrid?

  • running pdb from within pdb

    - by Andrew Farrell
    I'm debugging an script that I'm writing and the result of executing a statement from pdb does not make sense so my natural reaction is to try to trace it with pdb. To paraphrase: Yo dawg, I like python, so can you put my pdb in my pdb so I can debug while I debug?

  • Tomcat and proxy request

    - by Raghuram
    I configure a default tomcat installation (running on "localhost" at port "8080") as a proxy server in my browser and try to connect to http://www.google.com. I would expect either an error message saying tomcat is not configured as a proxy server or I should get the contents of google website. Instead I get the index.html page of my tomcat installation. What is going wrong?

  • groovyx.net.ws.WSClient is having problems with ''soapenc:Array' Any workaround?

    - by ?????
    I'm trying to call a webservice (implemented with a .NET/ASP system) from groovy/grails using WSClient. I have no trouble accessing this service using the SOAPClient debugger (Todd Ditchendorf's program for OSX), but when i try it via groovy/grails, I get the error undefined simple or complex type 'soapenc:Array' Is there any solution? Looking at it with wireshark: It seems to have thrown this error even before it gets a chance to perform the transaction. The error is thrown right after WSClient has downloaded the second of two schemas referenced in he WSDL.

  • Any good source of explanatory documentation on ColorMatrix?

    - by mackenir
    I'd like to try using ColorMatrix, but am only able to find examples that convert an image to grayscale. And even then, they tend to be presented as a chunk of 'magic numbers' code with no explanation. Does anyone know of a 'tutorial' on how to use ColorMatrix? For example I'd be interested in converting a grayscale image to a color image, where white == transparent, and black = a solid color, with gray pixels somewhere in between. Could ColorMatrix do that?

  • Switching between landscape views

    - by Isacco
    What is the best way to switch between views that are both in Landscape mode? I've tried with a simple "Push and Pop" methods that work fine when I try them with Portrait views but when I do it with Landscape for some reason it does the switching like the method was supposed to work just for Portrait views and a the end of the switch it autorotates back to Landscape.... if anyone can help that would be greatly appreciated. Thanks in advance.

  • Giving event control back to xaml/callee to access check/uncheck

    - by dovholuk
    Hi All, I've scoured the Internet but my search-foo must not work if it's out there cause I just can't find the proper search terms to get me the answer I am looking for. So I turn to the experts here as a last resort to point me in the right direction. What I'm trying to do is create a composite control of a text box and a list box but I want to allow the control consumer to decide what to do when say the checkbox is checked/unchecked and I just can't figure it out... Maybe i'm going about it all wrong. What I've done thus far is to: create a custom control that extends ListBox expose a custom DP named "Text" (for the Text box but it's not the important part) craft the generic.xaml so that the list items have a default ItemTemplate/DataTemplate inside the DataTemplate I'm trying to set the "Checked" or "Unchecked" events expose 'wrapper' events as DPs in the custom control that would get 'set' via the template when instatiated As soon as I try something like the following (inside generic.xaml): <DataTemplate> <...> <CheckBox Checked="{TemplateBinding MyCheckedDP}"/> <...> </DataTemplate> I get runtime exceptions, the designer - vs2010 - pukes out a LONG list of errors that are all very similar and nothing I do can make it work. I went so far as to try using the VisualTreeHelper but no magic combination I could find would work nor would it allow me to traverse the tree because when the OnApplyTemplate method fires the listbox items don't exist yet and aren't in the tree. So hopefully this all makes sense but if not please let me know and I'll edit the post for clarifications. Thanks to all for any pointers or thoughts... Like I said maybe I'm heading about it in the wrong way from the start... EDIT (Request for xaml) generic.xaml datatemplate: <DataTemplate > <StackPanel Orientation="Horizontal" > <local:FilterCheckbox x:Name="chk"> <TextBlock Text="{Binding Path=Display}" /> </local:FilterCheckbox> </StackPanel> </DataTemplate> usercontrol.xaml (invocation of custom control) <local:MyControl FancyName="This is the fancy name" ItemChecked="DoThisWhenACheckboxIsChecked" <-- this is where the consumer "ties" to the checkbox events ItemsSource="{Binding Source={StaticResource someDataSource}}" />

  • One-to-many relationship with JDO in Google App Engine

    - by Marvin
    I've followed the GAE docs on setting up one-to-many relationship in JDO but I'm still having trouble in retrieving the collection data back. I have no problem getting the other non-collection fields back. Here are my classes: @PersistenceCapable public class User{ @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Key key; @Persistent private String uniqueId; @Persistent private String email; @Persistent private List<Address> addresses = new ArrayList<Address>() ; ... } @PersistenceCapable public class Phone{ @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Key key; @Persistent private String number; ... } public class UserDaoImpl implements UserDao { public void insertUser(User user) { if(user.getKey() == null) { com.google.appengine.api.datastore.Key key = KeyFactory.createKey(User.class.getSimpleName(), user.getEmail()); user.setKey(key); } PersistenceManager pm = PersistenceManagerWrapper.getPersistenceManager(); notNull(user); try { pm.makePersistent(user); } finally { pm.close(); } } @SuppressWarnings("unchecked") public User getUser(String uniqueId) { PersistenceManager pm = PersistenceManagerWrapper.getPersistenceManager(); Query query = pm.newQuery(User.class); query.setFilter("uniqueId == uniqueIdParam"); query.declareParameters("String uniqueIdParam"); User user = null; try { List<User> users = (List<User>)(query.execute(uniqueId)); //TODO abstract this if(users.size() > 0) user = users.get(0); } finally { pm.close(); } return user; } } public class UserDaoImplTest { @Test public void getUserTest() { User user = createTestUser(); assertNotNull("The user object should not be null", user); userDao.insertUser(user); User returnedUser = userDao.getUser(TEST_USER_ID); assertNotNull("The returnedUser object should not be null", returnedUser); Assert.assertPropertyEqualsExcludeProperties("User Object", user, returnedUser, ""); } } When I run the test, all the properties for User is populated but the list of Phone if I get is empty.
