c++ - Visual Studio 2010 debugger points to wrong line -

-

Debugger in Visual Studio 2010 recently pointed to the wrong lines and / or skipping lines, I do not know why this is it. This is a CUDA project and only occurs in CUDA files, I have noticed the following:
  • It is always in the same part of the program.
  • These rows are always the same, i.e. not random.
  • Add additional code hereafter criminals lines change that line.
  • This only occurs in .cu -files. Running the code in .cpp -file does not recreate the problem.

    Whatever I have tried:

    • Clean and reconstruct the solution.
    • Install SP1 for MSVC 10 and make all possible updates through Windows updates
    • Use No to optimize in debug mode C / C ++ and CUDA C / C ++
    • Delete all created files manually and then rebuild from the Solutions folder.
    • Folder C: \ Windows \ Microsoft.NET \ Framework \ v4.0.30319 \ Temporary ASP.NET Files
    • Solution to the use of source files only Retrieving.
    • Disabling my extensions.

      I have been able to reduce this code which can reproduce the problem. Keep in mind that this code should be inside the .cu-file and needs to be compiled for C / C ++ with the Quma compiler. Incorporating incentive is not really necessary, but this example tells me what problems are coming to me. A short example is behind. 

        #include & lt; Boost / numeric / ublas / matrix.hpp & gt; Promotion :: Numeric :: ublas :: matrix; Struct foo {foo (): mat (null) {} matrix & lt; Float & gt; * Mat; }; Bool Funk (foo * data) {Boole status; // & lt; - Status of left position = false; If (status) {std :: cout & lt; & Lt; "Test \ n"; Return (status); // & lt; - The error report is given here} int size = data-> mat-> size 1 (); // Instead of changing status; } Int main (int args, char * argv []) {func (NULL); 0 error by zero error indicator return; }   
       Does anyone know how it is sorted or how can it be?  
       
       The small example is just showing the skipping line. No external library is necessary.  
        bool func () {bool status; // & lt; - Status of left position = false; Return status; } Int main (int args, char * argv []) {func (); Return 0; } 
       
       Since the program contains only CPU instructions and variable declarations in which no construction is constructed There is no instruction, no debugger will stop there, it executes just the instructions and then uses the debugging information that the compiler is provided to find the relevant line of the source code.

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...
