design patterns - Interface of Interface using C# -

-

I do not know the following is weird but really needs an interface for an interface & lt; T & gt;

Example: 

  Public Interface IRAPSorporation & lt; T & gt; To store it in a list without specifying a specific implementation. {Add Zero (T-NNTTY); Remove zero (T unit); IEnumerable & LT; T & gt; find all(); IEnumerable & LT; T & gt; Search (Expression & lt; Funk & lt; T, bool & gt; & gt; Forecasting); } Public Interface IUnitOfWork {// Here I would like to store only one irapository without the implementation of ILIST & lt; IRepository & lt; ** I have to specify the implementation here ** & gt; & Gt; Repositories {receive; Set; } Bool Commit (); }   
 You can recommend me better ways to do this. This is only what I have to do ...  
  Thanks   
  Edit   
 I Can not provide a non-normal interface because I'm using it like this:  
  Public class generic repository & lt; T & gt; : IRAPSorgetry & Lt; T & gt; {... general repository methods ...} // special repositories ... public class MyTableClassRepository & lt; MyTable & gt; : Generic Repository & lt; MyTable & gt; {Public MyTableClassRepository (database reference): base (context) {}}    
 
 
 consider The following design  
  Public Interface IUnitOfWork: IDisposable {T GetRepository & lt; T & gt; () Where T: Class; Zero attendance (); }   
 In the implementation of the unitoffer you can use the IoC container (Autofac in the example below)  
  public class UnitOfWork: IUnitOfWork {Private static IContainer _container; Hashtable _repositories = new hashtable (); Get the Public Static Module CurrentRepositoriesModule { Set; } Public Universe () {var Builder = New Containerbuilder (); If (CurrentRepositoriesModule! = Zero) Builder Registrar Module (CurrentRepositoriesModule); _ Container = Builder. Build (); } Public T GetRepository & lt; T & gt; () Where T: class {var targetType = typeof (T); If (! _positories.kantensky (target type)) {_repositories.Add (target type, _ container.resolive & lt; T & gt; ()); } Return (t) _ repositories [targetType]; } Public Zero Save Changes () {New Notificied Exposition (throw); }}

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

-
I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
