  • Cant free memory.

    - by atch
    In code: int a[3][4] = {1,2,3,4, 5,6,7,8, 9,10,11,12}; template<class T, int row, int col> void invert(T a[row][col]) { T* columns = new T[col]; T* const free_me = columns; for (int i = 0; i < col; ++i) { for (int j = 0; j < row; ++j) { *columns = a[j][i]; ++columns;//SOMETIMES VALUE IS 0 } } delete[] free_me;//I'M GETTING ERROR OF HEAP ABUSE IN THIS LINE } int main(int argc, char* argv[]) { invert<int,3,4>(a); } I've observed that while iterating, value of variable columns equals zero and I think thats the problem. Thanks for your help.

  • Why is there a margin at the top of my browser?

    - by fmz
    I have a web page that is displays differently in Firefox and Safari (IE testing yet to come). The page displays as expected in Safari, but there is a 50px margin between the body and the HTML that I can't determine what is causing it. Here is the CSS for the body: body { font-size: 13px; line-height: 1.333em; background: #f6eaae url(../_images/parchment-big.jpg) no-repeat center top; font-family: "Lucida Grande", Lucida, Verdana, sans-serif; color: #323232; } I would really appreciate some assistance in finding what is causing this difference. Ideally the Firefox version is better because it gives that extra breathing room at the top. Thanks.

  • What is the best way to embed controls in a list/grid

    - by Brad
    I have a table of about 450 rows that I would like to display in a graphical list for users to view or modify the line items. The users would be selection options from comboboxes and selecting check boxes etc. I have found a listview class that extends the basic listview to allow for embeding objects but it seems kind of slugish when I load all the rows into it. I have used a datagridview in the past for comboboxes and checkboxes, but there was a lot of time invested in getting that up and running...not a big fav of mine. I am looking for sugestions how I can do this with minimal overhead. thanks c#, vs2008, .net 2.0, system.windows.forms

  • How can I view javadocs that have been added to a maven repository?

    - by Coderer
    I know I can use maven to pull the javadocs for an artifact (if they've been added), which should come through as a JAR (right?), which I can then unpack and browse. My problem is, I'm trying to figure out which of a series of artifacts have the particular package I'm hunting for. I could download a half-dozen javadoc packages, unpack all of them, then open the index files one at a time, but that sounds like it would be pretty unpleasant. There must be a better way! I noticed that Nexus supports javadoc artifact browsing, but apparently only in the Pro version (which we do not have, and are unlikely to get any time soon). I'd prefer a GUI solution, though I'd settle for a command line answer, provided it's something along the lines of showmethedocs groupId:artifactId [version].

  • How do I keep JTextFields in a Java Swing BoxLayout from expanding?

    - by Matthew
    I have a JPanel that looks something like this: JPanel panel = new JPanel(); panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS)); ... panel.add (jTextField1); panel.add (Box.createVerticalStrut(10)); panel.add (jButton1); panel.add (Box.createVerticalStrut(30)); panel.add (jTextField2); panel.add (Box.createVerticalStrut(10)); panel.add (jButton2); ... //etc. My problem is that the JTextFields become huge vertically. I want them to only be high enough for a single line, since that is all that the user can type in them. The buttons are fine (they don't expand vertically). Is there any way to keep the JTextFields from expanding? I'm pretty new to Swing, so let me know if I'm doing everything horribly wrong.

  • Is it possible to write a Java printf statement that prints the statement itself?

    - by polygenelubricants
    Is it possible to have a Java printf statement, whose output is the statement itself? Some snippet to illustrate: // attempt #1 public class Main { public static void main(String[] args) { System.out.printf("something"); } } This prints something. So the output of attempt #1 is not quite exactly the printf statement in attempt #1. We can try something like this: // attempt #2 public class Main { public static void main(String[] args) { System.out.printf("System.out.printf(\"something\");"); } } And now the output is System.out.printf("something"); So now the output of attempt #2 matches the statement in output #1, but we're back to the problem we had before, since we need the output of attempt #2 to match the statement in attempt #2. So is it possible to write a one-line printf statement that prints itself?

  • Does C++ have a proper implementation of interface that does not use vtable?

    - by gilbertc
    Does C++ have a proper implementation of interface that does not use vtable? for example class BaseInterface{ public: virtual void func() const = 0; } class BaseInterfaceImpl:public BaseInterface{ public: void func(){ std::cout<<"called."<<endl; } } BaseInterface* obj = new BaseInterfaceImpl(); obj->func(); the call to func at the last line goes to vtable to find the func ptr of BaseInterfaceImpl::func, but is there any C++ way to do that directly as the BaseInterfaceImpl is not subclassed from any other class besides the pure interface class BaseInterface? Thanks. Gil.

  • Masking a bit in C returning unexpected result

    - by Eamorr
    0x7F000000 is 0111 1111 0000 0000 0000 0000 0000 0000 in 32 bit binary. 0x01000058 is 0000 0001 0000 0000 0000 0000 0101 1000. When I AND the two numbers together I expect 0000 0001 0000 0000 0000 0000 0000 0000, but for some reason I get 0. Here is my code: #define MASK_binop 0x80000000 #define MASK_operation 0x7F000000 int instruction=atoi(line); if((MASK_binop & instruction)>0) printf("binop\n"); else if((MASK_operation & instruction)>0) printf("operation\n"); Each of the above comparisons keeps returning zero. Is it something to do with 32/64 bits? I'm using 64-bit compiler.

  • python how to put data on y-axis when plotting histogram

    - by user3041107
    I don't quite understand how to control y - axis when using plt.hist plot in python. I read my .txt data file - it contains 10 columns with various data. If I want to plot distribution of strain on x axis I take column n.5. But what kind of value appears on y axis ??? Don't understand that. here is the code: import numpy import matplotlib.pyplot as plt from pylab import * from scipy.stats import norm import sys strain = [] infile = sys.argv[1] for line in infile: ret = numpy.loadtxt(infile) strain += list(ret[:,5]) fig = plt.figure() plt.hist(strain, bins = 20) plt.show() Thanks for help!

  • What files to be included under VSS 6.0

    - by kheat
    For our .net 3.5 web project, what are the files which needs to be included under VSS 6.0? We have a distributed team of three vendors working on separate modules of our .net portal and all of them maintain their own setup and during release they send across the final build. No surprises that this has caused much headache and we have decided that we will keep this environment under our control and checkout the files when required. This is a multi-part questionnaire and to clear some basics first, we would like to know which are the important files to be kept under VSS6.0. Yes we know VSS 6.0 is outdated but we are playing a catchup game and till we move either to TFS or Subversion( atleast six months down the line) we need a VSS strategy. TIA

  • How to default-initialize local variables of built-in types in C++?

    - by sharptooth
    How do I default-initialize a local variable of primitive type in C++? For example if a have a typedef: typedef unsigned char boolean;//that's Microsoft RPC runtime typedef I'd like to change the following line: boolean variable = 0; //initialize to some value to ensure reproduceable behavior retrieveValue( &variable ); // do actual job into something that would automagically default-initialize the variable - I don't need to assign a specific value to it, but instead I only need it to be intialized to the same value each time the program runs - the same stuff as with a constructor initializer list where I can have: struct Struct { int Value; Struct() : Value() {} }; and the Struct::Value will be default-initialized to the same value every time an instance is cinstructed, but I never write the actual value in the code. How can I get the same behavior for local variables?

  • GetValue on static field inside nested classes.

    - by Sir Gallahad
    Hi... I have the following class declared. I need to retreive the class structure and the static values without instanciate it. public MyClass() { public static string field = "Value"; public nestedClass() { public static string nestedField = "NestedValue"; } } I've successfuly used GetFields and GetNestedType to recover the class structure and GetValue(null) works fine on field, but not on nestedField. Let me sample: var fi = typeof(MyClass).GetField("field", BindingFlags.Public | BindingFlags.Static); var nt = typeof(MyClass).GetNestedType("nestedClass", BindingFlags.Public); var nfi = nt.GetField("nestedField", BindingFlags.Public | BindingFlags.Static); // All the above references are detected correctly var value = fi.GetValue(null); // until here everything works fine. value == "Value" var nestedValue = nfi.GetValue(null); // this one does not work!! Anyone knows why the last line does not work and how to work around? Thanks.

  • Strange pattern matching with functions instancing Show

    - by Sean D
    So I'm writing a program which returns a procedure for some given arithmetic problem, so I wanted to instance a couple of functions to Show so that I can print the same expression I evaluate when I test. The trouble is that the given code matches (-) to the first line when it should fall to the second. {-# OPTIONS_GHC -XFlexibleInstances #-} instance Show (t -> t-> t) where show (+) = "plus" show (-) = "minus" main = print [(+),(-)] returns [plus,plus] Am I just committing a motal sin printing functions in the first place or is there some way I can get it to match properly? edit:I realise I am getting the following warning: Warning: Pattern match(es) are overlapped In the definition of `show': show - = ... I still don't know why it overlaps, or how to stop it.

  • Creating quick GUI front ends

    - by Jeenu
    Hi, I wanted to have a GUI front-end for a script that accepts numerous command-line options, most of them are UNIX paths. So I thought rather than typing them in (even with auto-completion) every time, I'd create a GUI front end which contains text boxes with buttons beside them, which when clicked will invoke the file browser dialogue. Later, I thought I'd extend this to other scripts which would sure require a different set of GUI elements. This made me think if there's any existing app that would let me create a GUI dialog, after parsing some kind of description of the items that I want that window should contain. I know of programs like Zenity, but I think it's doesn't give me what I want. For example, if I were to use it for the first script, it'll end up flashing sequence of windows in succession rather than getting everything done from a single window. So, basically I'm looking at some program that lets me create a window from a text description, probably XML or the like. Please suggest. Thanks Jeenu

  • Can you make a python script behave differently when imported than when run directly?

    - by futuraprime
    I often have to write data parsing scripts, and I'd like to be able to run them in two different ways: as a module and as a standalone script. So, for example: def parseData(filename): # data parsing code here return data def HypotheticalCommandLineOnlyHappyMagicFunction(): print json.dumps(parseData(sys.argv[1]), indent=4) the idea here being that in another python script I can call import dataparser and have access to dataParser.parseData in my script, or on the command line I can just run python dataparser.py and it would run my HypotheticalCommandLineOnlyHappyMagicFunction and shunt the data as json to stdout. Is there a way to do this in python?

So why can't I sent in GUIDs? even ones that are copied right from the database and must be valid as they where allowed into the db.

  • How Matlab calculates the camera view angle?

    - by iman
    I am using matlab to visualise a scene. In order to zoom in the scene, I can do that by eather: - Fix the cameraposition and the cameratarget and change the cameraviewangle.or - Fix the cameratarget and the cameraview angle and moving the camera along the viewing line (defined by the cameraPosition and the cameraTarget). I know how to set the values of cameraposition CameraTarget and viewangle, but I do not how to define the optimal view angle. In auto mode of cameraviewangle, matlab calculate the smalest view angle that capture all the scene from the specefied camera position. I appreciate any help in understanding this. Iman

  • [WordPress] Need help with remove_action()

    - by gabriel
    I'm trying to remove the unsightly embedded <STYLE> tag the built-in Recent Comments widget puts in my <HEAD>, but I can't seem to get the syntax right. It originally calls add_action( 'wp_head', array(&$this, 'recent_comments_style') ); to add it (in wp-includes/default-widgets.php, line 609), and I'm trying to undo it. I think it should be something like this: remove_action('wp_head', 'WP_Widget_Recent_Comments::recent_comments_style'); but with all the variations I've tried I still can't get it right. Does anyone know how to achieve this? Possibly Helpful: Function Reference: remove_action

  • Is there a c++ library that provides functionality to execute an external program and read its outpu

    - by BD at Rivenhill
    Basically, I'm looking for something that will allow me to replicate the following Perl code: my $fh = new FileHandle; $fh->open("foo |"); while (<$fh>) { # Do something with this line of data. } This is in the context of Linux, so a library that is specific to Windows will not help. I know how to write a program that does fork/exec/dup2 and all that basic shell-type jazz, but there are some fiddly details involving terminals that I don't feel like messing around with (and I don't have a copy of "Advanced Programming in the UNIX Environment" or a similar reference handy), so I'm hoping that someone has already solved this problem.
