map - Erlang list of tuples with another list of tuples inside to a single list -

-

So, I'm searching for a better way to do this.

Incoming data is something like this (this can be a lot more than an example, but only one sub-level): 

  [[{1, "1"}, {D2, "2"}, {sub_data, [{d1, "3"}, {d2, "4"}}}], [{d1, "5"}, {d2, "6"}]] < / Code>  
 I need to sort it ["5", "6"}]   
 
 [{"" 1 "," 2 " }>  
 Now I am doing this, which is not a great way:  
  List: Map (Fun (Data) -> gt; [G (D1, Data), F: G (D2, Data)} + [["> & gt; ++ F: G (D1, SubData) }, {"& Gt; + + F: G (D2, SubData)}} SubData and LE    
 
 
 Who I came with:  
  changes (input) - & gt; List: Flaton (Lists: Map (Interesting - Item - - Change_Eystem (item, []) End, Input). Change_item (item, prefix) - & gt; {Kvs, subdata} = lists: (funny ({sub_data, _}) -> gt; false; (_) -> right end, item), res0 = list_to_tuple (lists: map (fun ({_, Value}} ([sub_data, SubItem}) -> change_item (subtitle, "" gt; end), subdata); (Resume, ]. (-) [-] Testing () -> Transforming Case ([[[1], "1"}, {d2, "2"}, {sub_data, [{d1, "3"}, {d2, "4" }}}, [[D1, "5" {"" 1 "," 2 "}, {"> 3 "," & gt; 4 "}, {" 5 "," 6 "}] - [& gt; Format: "format" (invalid, silk), end   Pre>

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...
