c++11 - Eclipse C++ std::vector methods invalid parameters errors -

-

I'm working on an Android application that uses OpenCV 2.4.9 and NDKR 9 as a dependency. I also use Eclipse 4.4 Luna as IDE with the installation of CDT Plugin 8.4.

Whenever I'm trying to use methods std :: vector.at (int), or the "[]" method, I get strange errors. For example, consider the code: 

  #include & lt; Vector & gt; ......................... structure customs {int level; Point First Point, Second Point, Midwaypoint; }; ......................... Inc maxElemNr = 10; Std :: vector & lt; CustomStread & gt; CustomStructVector (maxElemNr); ......................... for (int i = 0; i & lt; customStructVector.size (); i ++) {if ( CustomStructVector.at (i) .level == 0} {}}   
 at  customStructVector.at (i)  Eclipse tells me the following:  
 
 Invalid argument 'candidates: As a result, together with the Evidence & amp; On the (?) Continent, along with the results of Avance & amp; If I want to use the "[]" operator instead of "on (index)" method, then I get the following:  As a result of the Avidha vector vector (?) '  
 [I] .level  tells me that the field  level  is not found.  
 I'm called an expert C / C ++ sign, and I'm new to working with Java with NDK coming from the background, I can add any code to  CustomStruct  The call was expected to get the object of  customStructVector.at (i)  or  customStructVector [i] . >, Such that I can then use the field  level  on my object to read its value.  
 In addition, my vector  
  int maxElemNr = 10; Std :: vector & lt; CustomStruct & gt; CustomStructVector; CustomStructVector.reserve (maxElemNr);   
 I found:  
 
 invalid argument 'candidates are: zero reserved (?)'   
 I searched Is the answer to that, and came with the principle that eclipse can not use the c + + 11 version of std library?  
 I have read about the vector class. Apart from this, this issue is similar to the question being asked.  
 will provide more information about my environment and in this way, if necessary, solve it, because it is a barrier to my project so far ..  
 What am I doing wrong? There was no problem in compiling and running the code before using the  std :: vector  class.  
  LE:  Apparently workaround  & amp; (As a result of EvidenceWater data () + i) - & gt; Level is accredited by the editor, and compiles the code, still want to use  std :: vector , though it is considered in use.   
 
 
 I had the same problem It works in the Visual Studio compiler, but when I access the vector element If I try to do it, I get the exact same error.  
 Although it seems that if you do not use 'A', then this custom-operator I) Use custom architecture (I),  
 It is weird that I did not understand it in detail. Please note that if you have a vector, then you have to put the results to reach type of members.

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...
