c# - FluentValidation SetCollectionValidator for derived types -

-

How do I set assumptions on the collection types of derivative types? Class BaseClass {} Class DerivedClass: Base Class {} Class SomeClass {Public IEnumerable & lt; BaseClass & gt; Base Classes {Get; Set; }} Category DerivedClassValidator: abbetvilidetter & lt; DerivedClass & gt; {} Class SomeClassValidator: abbetvilidetter & lt; SomeClass & gt; {Public SomeClassValidator () {RuleFor (x = & gt; x.BaseClasses). Line SetCollectionValidator (New DerivedClassValidator); }}

Just wondering ...

Is this a way to insert it as a special type 

  RuleFor (x = & gt; x.ComeCollection) .CastTo (SomeDerivedType) SetCollectionValidator (New SomeDerivedValidator ());  
 
 You can use conditional rows of rules to validate the collection, In which the various derivative objects type.  
 Assume that your next class hierarchy is:  
  public class BaseClass {public string name {get; Set; }} Public class DerivedClassOne: Base class {public int count {get; Set; }} Public Category DerivedClassTwo: Base Class {Public Double Value {get; Set; }}   
 and  BaseClass  container class with collection of items:  
  public class ContainerClass {public list & lt; BaseClass & gt; Collection {Received; Set; }}   
 The main idea is to create a validating class, which is responsible for all class hierarchy recognition:  
  public class CommonBaseClassValidator: AbstractValidator & lt; BaseClass & gt; {General CommonBaseClassValidator () {// General rules for all base class types RuleFor (x = & gt; x.Name) NotEmpty (); // Special rule for base when (model => model.GetType () == type (base class), () => gt; {RuleFor (x = & gt; x.Name). Lambic (0, 10); / / add rule here}}; // Special rules for derivative types when (model = & gt; models. GetType () == type (DerivedClassOne), () = & gt; {RuleFor (model = & gt; (DerivedClassOne) model). , 9), // add rule here}}; When (model = & gt; model.GetType () == type (DerivedClassTwo), () => {RuleFor (model => (DerivedClassTwo) model) .pice) .GreaterThan (1000); // Add rules here}}; }}   
 and register this class as a collection object validator:  
  public class container wizard: abbetvilidetter & lt; Container Class & gt; {Public container () {RuleFor (model = & gt; model.Collection). SetCollectionValidator (New CommonBaseClassValidator ()); }}

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...
