问题 TL;DR at bottom A little back story for context. I'm creating an xml tool that will enable folks to input data needed for a game we're making without having to worry about hand-jobbing XML directly. The tool will output various XML files to be used by the game engine (for example, complex NPC Dialogue nodes with references to scripts to run when a given piece of dialogue is used... basically all the data to feed the game engine). I'm stuck trying to figure out a perplexing issue I'm having...

问题 Is it possible to give UserControl's Resources(Or one of its resource) as UserControl's DataContext?

问题 I am trying to do something that should be simple, but think I am just not seeing the answer. I have a List with several strings. I would like to bind it to a DevExpress DXGrid. It appears that the grid is showing the correct number of row, but not displaying my text. I am using the MVVm patern and have seperated my ViewModel and View. Thanks for the help. Here is the XAML code: <dxg:GridControl Grid.Row="0" DataSource="{Binding Path=ErrorLog}" > <dxg:GridControl.Columns> <dxg:GridColumn

问题 I implemented Service for listening user location: public class ListenLocationService extends Service { private final IBinder mBinder = new LocalBinder(); public interface ILocationService { public void StartListenLocation(); public Location getUserLocation(); } public class LocalBinder extends Binder implements ILocationService{ LocationManager locationManager; LocationListener locationListener; Location userLocation = null; public void StartListenLocation() { locationManager =

问题 I have created three data tables by pulling data from an sql database. DT1, DT2, DT3. I have added these three tables to a data set, myDS. I have added relations between these three tables. I then dragged a DataGridView onto my form and I want to bind the three tables to the DataGridview. So I added my dataset DS to a dataview manager, myDVM. I bound myDVM to a bindingsource, bindingSource1, and made it the data source for the DataGridView. I am not sure how to bind the tables I want from

问题 Is there any difference between limiter 1 and limiter 2? var limiter1 = function(limiter){ return function(item){ return item > limiter; }; }; var limiter2 = function(limiter){ return function(limiter,item){ return item > limiter; }.bind(this,limiter); }; 回答1: In most cases, they will function identically. However... If you ever start to actually use the value of this , the function returned by limiter1 will be unbound (so a consumer could change the value with a call to Function.prototype
