Create a Generic List of Generic objects in C# -

-

I have a generic class for which I would like to create a general list, where the underlying classes apply the same interface However, all of the given interface is not implemented.

Describing the problem would be an easy example. Intermediate Interface Isoming {} Internal Segment Type: ISOMTI {} Internal Square Theatings: Isoming {} Internal Class SomethingElse {} Internal Square Generic Tings & lt; T & gt; {} Internal range DoThings {void Main ()} {var thing1 = New GenericTeat; This lesson & gt; (); Var thing2 = new generic typing & lieutenant; That Typing & gt; (); Var Talk 3 = New Generic Ting & lt; SomethingElse & gt; (); ** var thingList = new list & lt; Generic typing & lt; ISomething & gt; & Gt; () {Thing1, thing2}; **}

}

I'm unable to create a list of things which is a way of putting two things that apply the same interface in the general collection, while The interface is not currently interrupted to protect the generic tog class.

It is possible if you use it: 

  internal Interface IGenericThing & lt; Out T & gt; {} Internal category generic typing & lt; T & gt; : IGenericThing & lt; T & gt; {} Zero main () {var thing1 = new genericizing & lt; This Taking & gt; (); Var thing2 = new generic typing & lieutenant; That Typing & gt; (); Var Talk 3 = New Generic Ting & lt; SomethingElse & gt; (); Var Talk List = New List & lt; IGenericThing & lt; ISomething & gt; & Gt; () {Thing1, thing2}; }   
 Note that this is only possible when using  T  only  IGenericThing & lt; T & gt;  is done as an output, never in the form of an input! (It is unused, as my example is also acceptable, though, obviously, useless)

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...
