  • Printing Script Codes.

    - by Spelljack
    I wanna print out script's codes after the output. The script goes on different ways on the way it calls. So i wanna see it when script runs. is there any function that prints all script codes as the way it writed. Example: $foo = "bar"; $foo .= " is my bar"; function foobar() { // do some stuff here } i wanna see the codes just like this. is there a way to do this? without file_get_contents(), file(), readfile() functions?

  • C++ & C#, how to create wrapper dll in C++ for C# to call instance function in C++ dll?

    - by 5YrsLaterDBA
    Received an unmanaged C++ dll with instance functions which need to be called from my C#. need to write a wrapper C++ dll to bridge the C# and original C++ dll as suggested by experts here. it is new to me and want to learn from you. Header file of the original C++ dll likes this: class EXPORT_MACRO NB_DPSM { private: string sFileNameToAnalyze ; public: NB_DPSM(void); ~NB_DPSM(void); void setFileNameToAnalyze(string FileNameToAnalyze) ; int WriteGenbenchData(string& message) ; }; Start from a Class Library project template or CLR Empty Project template? What's the wrapper code should look like? Anywhere has step by step example for this? thanks,

  • Running interrelated methods continously using java

    - by snehalata
    I have written application which downloads data from a website every 10 mins and writes to a file.Then these files are merged into one file and then R program is run on this merged file to perform sentiment analysis and result is stored in hbase. I want the process of merging files,running R and then storing to HBase to run continuosly on the downloaded data. For running R,we are running R script from java program.We have used Runtime.getRuntime().exec() method to run R program but it doesn't wait for R program to complete and method in the next line starts executing.Using p.waitFor() did not help . What approach should I use to do merge then run R and finally store results in Hbase?Should I use timer class??

  • Storing SQL in MySQL: Insert as Text?

    - by Tim F
    Hey all, Working in a team environment, each one of us has put together our own list of SQL statements that we use to help with our day to day job functions. As the case often is, there may be some redundancy with this, and we are often in need of each other's statements. To circumvent this, I'm looking to put together a small app that can be used to store and search for these SQL statements. To begin with, I'm keeping it basic, just storing and searching the statements. This may build out to be the actual execution at some point in the future, but I'm not concerning myself with this at the time. This will be built with PHP and MySQL - Should I store the SQL as text, or is there something that I need to be concerned with?

  • C++: String and unions

    - by sub
    I'm having a (design) problem: I'm building an interpreter and I need some storage for variables. There are basically two types of content a variable here can have: string or int. I'm using a simple class for the variables, all variables are then stored in a vector. However, as a variable can hold a number or a string, I don't want C++ to allocate both and consume memory for no reason. That's why I wanted to use unions: union { string StringValue; int IntValue; } However, strings don't work with unions. Is there any workaround so no memory gets eaten for no reason?

  • Can single-buffer blocking WSASend deliver partial data?

    - by CodeAngry
    I've pretty much always used send() with sockets and now I'm moving onto the WSA functions. With send(), I have a sendall() helper that ensured all data is delivered even if it didn't happen in one try and a partial send occurred on first call. So, instead of learning the hard way or over-complicating code when I don't have to, decided to ask you: Can a blocking WSASend() send partial data or does it send everything before it returns or fails? Or should I check the bytes sent vs. expected to send and keep at it until everything is delivered? ANSWER: Overlapped WSASend() does not send partial data but if it does, it means the connection has terminated. I've never encountered the case yet.

  • ruby code inside quotes

    - by chief
    I would like to embed videos and have managed to to do so by manually coding the url in where needed. If my url is stored in <%= @vid.url %, how can I use that string for the value and src parameter? <object width="480" height="385"><param name="movie" value="http://www.youtube.com/videos/abc123"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/videos/abc123" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="385"></embed></object>

  • Pass, edit and return variable in C

    - by Supertecnoboff
    I am new to C programming and recently I have been playing around with functions in C programming. But I have a simple problem: Basically I want to pass an integer to a function, have the function edit it and then pass back the integer to the main function. I am working on this but it isn't working..... Here is my code: int update_SEG_values(int DIGIT_1, int DIGIT_2) { // How many tens in the "TEMP_COUNT". DIGIT_2 = ((TEMP_COUNT) / 10); // How much is left for us to display. TEMP_COUNT = TEMP_COUNT - ((DIGIT_2) * 10); // How many ones. DIGIT_1 = ((TEMP_COUNT) / 1); return(DIGIT_1, DIGIT_2); } What am I doing wrong here?

  • DataTable from TextFile?

    - by Craig
    I have taken over an application written by another developer, which reads data from a database, and exports it. The developer used DataTables and DataAdaptors. So, _dataAdapter = new SqlDataAdapter("Select * From C....", myConnection); and then ExtractedData = new DataTable("CreditCards"); _dataAdapter.Fill(ExtractedData); ExtractedData is then passed around to do different functions. I have now been told that I need to, in addition to this, get the same format of data from some comma separated text files. The application does the same processing - it's just getting the data from two sources. So, I am wondering if I can get the data read into a DataTable, as above, and then ADD more records from a CSV file. Is this possible?

  • IIS, Apache, and header()

    - by MetalAdam
    I'm working on migrating a website from an external server (running Apache) to a local server (running IIS), and have come across an issue that I can't seem to resolve. The site is using a custom Joomla plugin that grabs some graphics stored in a mysql database (for e.g. http://www.norfolktourism.ca/index.php?option=com_bdirectory&task=image&cid=191). However, when I migrate the site to the local server, the images are broken. Upon further exploration, I've discovered that somehow, when ran on the local server, their seems to whitespace (as in a new line) gets processed before the header() function is processed, hence breaking the image (however, I don't get an error - just a broken image). I'm absolutely baffled as to what the issue may be, as the code works fine on the external Apache server. Would anyone have any suggestions on possible resolutions?

  • including a string as a parameter to a function in a header file? c++

    - by Nara
    hello everyone, total newbie is here :) i have this header file, zeeheader.h, and i wrote some classes in it, i'm having problems giving a string as a parameter to one of the functions: class DeliTest { public: void DeliCheck(Stack*,string); void ComCheck (unsigned,string); bool EofCheck (unsigned,string); }; as i was implementinng it in the cpp file, i added #include to it, it seemed to be working, for example : as i was writing the "data." i got the "length()" appear by the intellisense, so i thought that it was working, but it wasn't. i got errors like: syntax error : identifier 'string' overloaded member function not found in 'DeliTest' this is one of the fucntions in the cpp file: bool DeliTest::EofCheck(unsigned i, string data) { if (i == data.length()-1) return 1; return 0; } am i supposed to be adding something to the header file??

  • How to efficiently render different things at different times in a game?

    - by Baqjohanson
    Sorry for the ambiguous title. What I am wondering is what is an efficient way to alternate rendering between lets say a main menu, options menu, and "in the game." The only two ways I've come up with so far are to have 1 render function, with code for each part (menu, ...) and a variable to control what gets drawn, or to have multiple render functions, and use a function pointer to point to the appropriate one, and then just call the function pointer. I always wonder how more professional games do it.

  • C# Get/Set Syntax Usage

    - by RoR
    These are declarations for a Person class. protected int ID { get; set; } protected string Title { get; set; } protected string Description { get; set; } protected TimeSpan jobLength { get; set; } How do I go about using the get/set? In main, I instantiate a Person Tom = new Person(); How does Tom.set/get?? I am use to doing C++ style where you just write out the int getAge() and void setAge() functions. But in C# there are shortcuts handling get and set?

  • How to reference filtered ng-repeat items from a controller in AngularJS

    - by ParkerDigital
    I have some JSON data that is rendered out via the ng-repeat directive, and the results are then filtered via some checkboxes/drop-downs, and some custom filter functions in my controller. I now want to add a function to my controller that is triggered by an 'ng-change' on some of the checkboxes, that can reference the current list of items in my 'ng-repeat'. I realise I can reference these values from a custom filter, for example $scope.filterProvider = function(item), but this function is then called for each and every item in the ng-repeat, which isn't what I want - I want the function to just be called each time a checkbox is checked/unchecked, and I need that function to be able to reference the items in my ng-repeat...does that make sense to anyone?! And if so, does anyone know how I can do that? Thanks :-)

  • I having a problem with the mysqli free() member function

    - by neo skosana
    Hi I have code where I connected to the database like so: $db = new mysqli("localhost", "user", "pass", "company"); Now when I query the database like so: //query calls to a stored procedure 'user_info' $result = $db->query("CALL user_info('$instruc', 'c_register', '$eml', '$pass', '')"); //I use the $result This query works well. Now when I try and free that result like so: $result->free(); or $result->close(); It seems like it doesn't do anything because $result is still set. When I try to run another query it gives me this error: Fatal error: Call to a member function fetch_array() on a non-object in... For me to run this other query I have to close the db conection and connect again, then it will work. I want to know if there is a way I could run the other query without having to disconnect and reconnect to the database. thanks in advance.

  • Network license control for a Java application

    - by user1461615
    I have been tasked with providing some form of network license control for a Java application. The app would be stored on a network drive and run from a client machine. The basic idea is that it will be able to work out how many times it is being run concurrently and prevent the N+1th user from running the software where N is the number of concurrent licenses the customer has purchased. Is this possible somehow with a Java application? I implemented a "solution" which relied on multi-cast UDP communication between the running instances of the application but this didn't work because on most networks this kind of communication is blocked by security measures. Is there a better way? I don't even mind if it requires JNI/JNA. N.B. The solution does not have to be that sophisticated or highly secure.

  • Storing SQL Tables for use in visual studio

    - by Raven Dreamer
    Greetings. I'm trying to create a windows form application that manipulates data from several tables stored on a SQL server. 1) What's the best way to store the data locally, while the application is running? I had a previous program that only modified one table, and that was set up to use a datagridview. However, as I don't necessarily want to view all the tables, I am looking for another way to store the data retrieved by the SELECT * FROM ... query. 2) Is it better to load the tables, make changes within the C# application, and then update the modified tables at the end, or simply perform all operations on the database, remotely (retrieving the tables each time they are needed)? Thank you.

  • Is it possible to wrap calls to statically linked 3rd party library?

    - by robusta
    Hi, I would like to trace calls to some 3rd party library which are made from another 3rd party library. Example: I want to trace calls to library A. My application statically links library B, which in turn is statically linked to library A. In case of dynamic linking I could write library A2 with wrappers for functions which I want to trace of library A and use LD_PRELOAD=A2.so. Then, my wrappers will be called instead, and I will see the trace. In my case I cannot use dynamic linking. Is it possible to achieve the same using static linking? Thanks, Robusta

  • lua function as argument in C

    - by Nil
    I'm going to pass a function to another function which should operate with the passed function. For example: handler(fun1("foo",2)) handler(fun2(1e-10)) The handler is something like calling the passed function many times. I'm going to bind handler, fun1, fun2 to C-functions. fun1 and fun2 are going to return some user data with a pointer to some cpp-class so that I can further recover which function was it. The problem now is that fun1 and fun2 are going to be called before passed to handler. But I don't need this, what I need is the kind of function and its parameters. However, I should be able to call fun1 and fun2 alone without handler: fun1("bar",3) fun2(1e-5) Is it possible to get the context the function is called from? While typing the question, I realized I could do following handler(fun1, "foo",2); handler(fun2, 1e-10);

  • MySQL pivot tables - covert rows to columns

    - by user2723490
    This is the structure of my table: Then I run a query SELECT `date`,`index_name`,`results` FROM `mst_ind` WHERE `index_name` IN ('MSCI EAFE Mid NR USD', 'Alerian MLP PR USD') AND `time_period`='M1' and get a table like How can I convert "index_name" rows to columns like: date | MSCI EAFE Mid NR USD | Alerian MLP PR USD etc In other words I need each column to represent an index and rows to represent date-result. I understand that MySQL doesn't have pivot table functions. What is the easiest way of doing this? I've tried this code, but it generates an error: SELECT `date`, MAX(IF(index_name = 'Alerian MLP PR USD' AND `time_period`='M1', results, NULL)) AS res1, MAX(IF(index_name = 'MSCI EAFE Mid NR USD' AND `time_period`='M1', results, NULL)) AS res2 FROM `mst_ind` GROUP BY `date I need to make the conversion on the query level - not PHP. Please suggest a nice and elegant solution. Thanks!

  • Is it poor practice to identify objects via an enumeration property, instead of using GetType()?

    - by James
    I have a collection of objects that all implement one (custom) interface: IAuditEvent. Each object can be stored in a database and a unique numeric id is used for each object type. The method that stores the objects loops around a List<IAuditEvent>, so it needs to know the specific type of each object in order to store the correct numeric id. Is it poor practice to have an enumeration property on IAuditEvent so that each object can identify itself with a unique enumeration value? I can see that the simplest solution would be to write a method that translates a Type into an integer, but what if I need an enumeration of audit events for another purpose? Would it still be wrong to have my enumeration property on IAuditEvent?

  • Implementing an iterator over binary tree using C++ 11

    - by user1459339
    I would like to create an iterator over the binary tree so as to be able to use range-based for loop. I understand I ought to implement the begin() and end() function first. Begin should probably point to the root. According to the specification, however, the end() functions returns "the element following the last valid element". Which element (node) is that? Would it not be illegal to point to some "invalid" place? The other thing is the operator++. What is the best way to return "next" element in tree? I just need some advice to begin with this programming.

  • C++: How to design a utility class?

    - by Martijn Courteaux
    Hi, The title says it all. But I don't know if I should go for static methods, just a header, a class, or something else? What would be best practice? But, I don't want to have an instance of a utility class. I want to add functions like: Uint32 MapRGB (int r, int g, int b); const char* CopyString(const char* char); // etc. You know: utility methods...
