  • Make ListView.ScrollIntoView Scroll the Item into the Center of the ListView (C#)

    - by Kirk
    ListView.ScrollIntoView(object) currently finds an object in the ListView and scrolls to it. If you are positioned beneath the object you are scrolling to, it scrolls the object to the top row. If you are positioned above, it scrolls it into view at the bottom row. I'd like to have the item be scrolled right into the center of my list view if it is currently not visible. Is there an easy way to accomplish this?

  • Cloud 9 and Grunt.js

    - by Michael Ryan Soileau
    I'm running grunt.js on Cloud9. Most everything is working correctly, except when I try to set this option: 'watch: { options: {livereload:true},' If I add that, the terminal states: 'Fatal error: listen EACCES' I'm guessing I need to use the sudo command to run that and since c9 doesn't let you run sudo, the command fails. But why is livereload a feature that requires permission? And is there any way around it?

  • MVVM load data during or after ViewModel construction?

    - by mkmurray
    My generic question is as the title states, is it best to load data during ViewModel construction or afterward through some Loaded event handling? I'm guessing the answer is after construction via some Loaded event handling, but I'm wondering how that is most cleanly coordinated between ViewModel and View? Here's more details about my situation and the particular problem I'm trying to solve: I am using the MVVM Light framework as well as Unity for DI. I have some nested Views, each bound to a corresponding ViewModel. The ViewModels are bound to each View's root control DataContext via the ViewModelLocator idea that Laurent Bugnion has put into MVVM Light. This allows for finding ViewModels via a static resource and for controlling the lifetime of ViewModels via a Dependency Injection framework, in this case Unity. It also allows for Expression Blend to see everything in regard to ViewModels and how to bind them. So anyway, I've got a parent View that has a ComboBox databound to an ObservableCollection in its ViewModel. The ComboBox's SelectedItem is also bound (two-way) to a property on the ViewModel. When the selection of the ComboBox changes, this is to trigger updates in other views and subviews. Currently I am accomplishing this via the Messaging system that is found in MVVM Light. This is all working great and as expected when you choose different items in the ComboBox. However, the ViewModel is getting its data during construction time via a series of initializing method calls. This seems to only be a problem if I want to control what the initial SelectedItem of the ComboBox is. Using MVVM Light's messaging system, I currently have it set up where the setter of the ViewModel's SelectedItem property is the one broadcasting the update and the other interested ViewModels register for the message in their constructors. It appears I am currently trying to set the SelectedItem via the ViewModel at construction time, which hasn't allowed sub-ViewModels to be constructed and register yet. What would be the cleanest way to coordinate the data load and initial setting of SelectedItem within the ViewModel? I really want to stick with putting as little in the View's code-behind as is reasonable. I think I just need a way for the ViewModel to know when stuff has Loaded and that it can then continue to load the data and finalize the setup phase. Thanks in advance for your responses.

  • UIModalPresentationFormSheet on iPad in landscape mode

    - by Ivan
    I created a UIViewController view from XIB with modalPresentationStyle set to UIModalPresentationFormSheet and everything works great in portrait mode. When I switch to landscape the view gets moved upperleft (it's not centered as it should be) and most part of it is clipped. Any ideas why this is happening and how to solve it? Thanks

  • Attempting to update multiple partial views from a single Ajax.ActionLink

    - by mwright
    I have a a partial view which contains other partial views. I am trying to the main partial view ( "MainPartialView" ) from an Ajax.ActionLink in a partial view contained by the main partial view ( "DetailsView" ). Everything appears to be called just fine and I can step through and it executes all of the code on the pages. However, after that is all done it throws this error in a popup box in visual studio: htmlfile: Unknown runtime error This error puts the break point in the MicrosoftAjax.js file, Line 5, Col 83,632, Ch 83632.

  • Change the width of Master in UISplitViewController

    - by Raj
    Hi, The iPad programming guide says that the splitView's left pane is fixed to 320 points. But 320 pixels for my master view controller is too much. I would like to reduce it and give more space to detail view controller. Is it possible by anyway? Edit: Link to the document which speaks about fixed width - http://developer.apple.com/iphone/library/documentation/General/Conceptual/iPadProgrammingGuide/UserInterface/UserInterface.html#//apple_ref/doc/uid/TP40009370-CH3-SW1 Thanks and Regards, Raj

  • Can't get gitosis and ssh to play nice on cygwin

    - by Noel Kennedy
    I have followed this guide to setting up gitosis on a windows 2003 server via cygwin. I have now got to a point where it largely works. I can clone, pull and push. The problem I am having is that I think I have not got the ssh bit right at all. When I connect via msysgit from machines and accounts where I have not created or uploaded ssh keys it works. Every time I clone, pull or push I get a password challenge for the 'git' user running on the server but basically I can execute git commands. When I connect with users with an ssh key in the ~/.ssh folder, I don't get the password challange and instead I get a permissions failure: DEBUG:gitosis.serve.main:Got command "git-upload-pack '/cris.git'" DEBUG:gitosis.access.haveAccess:Access check for 'teamcity@hhit24808' as 'writable' on 'cris.git'... DEBUG:gitosis.access.haveAccess:Stripping .git suffix from 'cris.git', new value 'cris' DEBUG:gitosis.access.haveAccess:Access check for 'teamcity@hhit24808' as 'writeable' on 'cris.git'... DEBUG:gitosis.access.haveAccess:Stripping .git suffix from 'cris.git', new value 'cris' DEBUG:gitosis.access.haveAccess:Access check for 'teamcity@hhit24808' as 'readonly' on 'cris.git'... DEBUG:gitosis.access.haveAccess:Stripping .git suffix from 'cris.git', new value 'cris' ERROR:gitosis.serve.main:Repository read access denied fatal: The remote end hung up unexpectedly I have uploaded the public rsa key into the key_dir folder. Here is my conf file: [gitosis] loglevel = DEBUG [group gitosis-admin] writable = gitosis-admin members = myemail@mydomain [group cris-developers] members = myemail@mydomain TeamCity@HHIT24808 writable = cris If it matters, I have generated a key without a passphrase as I believe this is necessary to enable ssh for automated scripts. When I use keys with a passphrase, I get challanged for the phrase but then get the same permissions problem. I have tried 'writable' and 'writeable' for permissions. Help!! Update 1: When I try to clone a non-existant repo, I get the same error message, co-incidence? Update 2: Wierd, I've got one machine and one login working. It seems to be something to do with the syntax for addressing git over ssh. This now works on one machine for one login: git clone git@servername:cris.git The same command fails for a user on another machine without an uploaded ssh key. But this command works (after being challanged for git@servername's password) git clone git@servername:/home/git/repositories/cris.git neither command works on a 2nd login whose ssh key has been uploaded

  • dynamic ContextMenu in TreeView vs. MVVM

    - by bitbonk
    I have a tree of ViewModels displayed as a TreeView (using HierarchicalDataTemplate). Each ViewModel instance has different commands that can be executed on it wich again are exposed as a list of command ViewModels for each item ViewModel. How can I create a single ContextMenu that opens at the TreeViewItem that was rightclicked and that populates its commands from the underlying item ViewModel's command ViewModels list? All in a decent MVVM fashion ...

  • MPVolumeView, avoid displaying "No Volume Available"

    - by Emil
    Hey. I have a project with a MPVolumeView in it. It is set up, and it works, the only thing is that when I mute the device, the text "No Volume Available" comes up instead of the MPVolumeView. The volumeView is initialized in the view volumeBounds, with that view's bounds. MPVolumeView *volumeView = [[[MPVolumeView alloc] initWithFrame:volumeBounds.bounds] autorelease]; [volumeBounds addSubview:volumeView]; [volumeView sizeToFit]; Thanks :)

  • MinGW/G++/g95 link problem - libf95 undefined reference to `MAIN_'

    - by pivakaka
    Hi folks, Summing up, my problem consists on compiling g95 objects inside a C++ application. Actually, I'm constructing an interface for an old fortran program. For this task, I'm using the wxWidgets GUI library, and calling fortran subroutines when necessary. At the beginning, I was developing the entire project compiling my fortran files with gfortran (which comes with GCC) and linking them with my app by the g++ -o... command. Everything was working fine but some numbers values calculated by my fotran subroutines returned NAN values. Doing some research, I realized that compiling my fortran files with gfortran with the -m32 flag, generates this NAN values problem. Although compiling with -m64 flag, my code works properly well. The only trouble here is that my App should be 32bits and then I tryed another compiller. Here I found g95 Fortran compiler, which compiles my fortran code and gives the right output on a 32bits environment. But when I'm trying to link these g95 objects into my program I see this following error: g++ -oCyclonTechTower.exe src\fortran\Modulo_Global.o src\fortran\Prop_Fisicas.o src\fortran\inversa.o src\fortran\tower.o src\fortran\PredadeCarga.o src\fortran\gota.o src\fortran\tadi.o src\view\SimulationORSATCustomDialog.o src\view\SimulationChildGUIFrame.o src\view\ParentGUIFrame.o src\view\ClientGUIFrame.o src\model\TowerData.o src\controller\SimulationController.o src\THEIACyclonTechTower.o ..\Resource\resource.o -Lc:\wxWidgets-2.6.4\lib -Lc:\MinGW\lib\gcc-lib\i686-pc-mingw32\4.1.2 -Bdynamic -Wl,--subsystem,windows -mwindows c:\wxWidgets-2.6.4\lib\libwx_mswu-2.6.a -lwxregexu-2.6 -lwxexpat-2.6 -lwxtiff-2.6 -lwxjpeg-2.6 -lwxpng-2.6 -lwxzlib-2.6 -lrpcrt4 -loleaut32 -lole32 -luuid -lwinspool -lwinmm -lshell32 -lcomctl32 -lcomdlg32 -lctl3d32 -ladvapi32 -lwsock32 -lgdi32 -lgcc -lf95 c:\MinGW\lib\gcc-lib\i686-pc-mingw32\4.1.2/libf95.a(main.o):(.text+0x32): undefined reference to `MAIN_' collect2: ld returned 1 exit status Build error occurred, build is stopped Time consumed: 1531 ms. I have already read the g95 Manual for integration with C++ and I'm actually calling these functions bellow for controlling the fortran environment: void g95_runtime_start(int argc, char *argv[]); void g95_runtime_stop(); I also included the g95 Fortran Runtime Library libf95.a and the libgcc.a into my linker command. Finishing, I don't have a main method implemented because this is managed by wxWidgets, and my fortran subroutines can not have a main function because this is a C++ program calling fortran functions. Can some of you guys help me with this problem? How can I fix this undefined reference to MAIN__ problem? Any idea will be much appreciated. Thanks in advance, George

  • Datatemplates while using theme does not work - WPF

    - by bobjink
    I am using the theme DarkExpression from WPF Futures. It does not seem to work well with datatemplates. Scenario 1: Here is how it looks like without datatemplates: Pic 1 Code: <ListView Name="playlistListView" ItemsSource="{Binding PlaylistList}" Margin="0" SelectionChanged="DatabindedPlaylistListView_SelectionChanged" Background="{x:Null}" Opacity="0.98"> <ListView.View> <GridView> <GridViewColumn Width="Auto" DisplayMemberBinding="{Binding Name}"> <GridViewColumnHeader HorizontalContentAlignment="Left" Content="Playlist" Tag="Playlist"/> </GridViewColumn> </GridView> </ListView.View> </ListView> Scenario 2: Here is how it looks like trying to use datatemplates while using the theme: Pic 2 Code: <ListView Name="playlistListView" ItemsSource="{Binding PlaylistList}" Margin="0" SelectionChanged="DatabindedPlaylistListView_SelectionChanged" Background="{x:Null}" Opacity="0.98"> <ListView.ItemTemplate> <DataTemplate> <Grid> <UserControls:SongDataTemplate Margin="4" /> </Grid> </DataTemplate> </ListView.ItemTemplate> </ListView> Scenario 3: Here is how it looks like trying to use datatemplates while overriding the theme: Pic3 Code: <UserControl.Resources> <Style x:Key="ListViewItemStretch" TargetType="{x:Type ListViewItem}"> <Setter Property="HorizontalContentAlignment" Value="Stretch"/> <Setter Property="Background" Value="Transparent" /> </Style> </UserControl.Resources> <Grid x:Name="LayoutRoot"> <ListView Name="playlistListView" ItemContainerStyle="{StaticResource ListViewItemStretch}" ItemsSource="{Binding PlaylistList}" Margin="0" SelectionChanged="DatabindedPlaylistListView_SelectionChanged" Background="{x:Null}" Opacity="0.98"> <ListView.ItemTemplate> <DataTemplate> <Grid> <UserControls:SongDataTemplate Margin="4" /> </Grid> </DataTemplate> </ListView.ItemTemplate> </ListView> I want to keep the theme style but I also want to use datatemplates to define how a playlist should look like. Any suggestions? Note: In scenario 2 and 3 I had to remove <ListView.View> <GridView> <GridViewColumn Width="Auto" DisplayMemberBinding="{Binding Name}"> <GridViewColumnHeader HorizontalContentAlignment="Left" Content="Playlist" Tag="Playlist"/> </GridViewColumn> </GridView> </ListView.View> Before the datatemplate would be used.

  • Using MVC2 to update an Entity Framework v4 object with foreign keys fails

    - by jbjon
    With the following simple relational database structure: An Order has one or more OrderItems, and each OrderItem has one OrderItemStatus. Entity Framework v4 is used to communicate with the database and entities have been generated from this schema. The Entities connection happens to be called EnumTestEntities in the example. The trimmed down version of the Order Repository class looks like this: public class OrderRepository { private EnumTestEntities entities = new EnumTestEntities(); // Query Methods public Order Get(int id) { return entities.Orders.SingleOrDefault(d => d.OrderID == id); } // Persistence public void Save() { entities.SaveChanges(); } } An MVC2 app uses Entity Framework models to drive the views. I'm using the EditorFor feature of MVC2 to drive the Edit view. When it comes to POSTing back any changes to the model, the following code is called: [HttpPost] public ActionResult Edit(int id, FormCollection formValues) { // Get the current Order out of the database by ID Order order = orderRepository.Get(id); var orderItems = order.OrderItems; try { // Update the Order from the values posted from the View UpdateModel(order, ""); // Without the ValueProvider suffix it does not attempt to update the order items UpdateModel(order.OrderItems, "OrderItems.OrderItems"); // All the Save() does is call SaveChanges() on the database context orderRepository.Save(); return RedirectToAction("Details", new { id = order.OrderID }); } catch (Exception e) { return View(order); // Inserted while debugging } } The second call to UpdateModel has a ValueProvider suffix which matches the auto-generated HTML input name prefixes that MVC2 has generated for the foreign key collection of OrderItems within the View. The call to SaveChanges() on the database context after updating the OrderItems collection of an Order using UpdateModel generates the following exception: "The operation failed: The relationship could not be changed because one or more of the foreign-key properties is non-nullable. When a change is made to a relationship, the related foreign-key property is set to a null value. If the foreign-key does not support null values, a new relationship must be defined, the foreign-key property must be assigned another non-null value, or the unrelated object must be deleted." When debugging through this code, I can still see that the EntityKeys are not null and seem to be the same value as they should be. This still happens when you are not changing any of the extracted Order details from the database. Also the entity connection to the database doesn't change between the act of Getting and the SaveChanges so it doesn't appear to be a Context issue either. Any ideas what might be causing this problem? I know EF4 has done work on foreign key properties but can anyone shed any light on how to use EF4 and MVC2 to make things easy to update; rather than having to populate each property manually. I had hoped the simplicity of EditorFor and DisplayFor would also extend to Controllers updating data. Thanks
