  • Passing arguments to a function?

    - by dfjhdfjhdf
    I need to learn how to pass an associative array to a function so that I could do the following within the function: function someName($argums) { if (gettype($argums) != 'array' || !array_key_exists('myOneKey', $argums) || !array_key_exists('myOtherKey', $argums)) { return false; } /*do other stuff*/ } (That's how I would do in PHP what I am looking for in JavaScript.)

  • PowerShell function won't return object

    - by Dan
    I have a simple function that creates a generic List: function test() { $genericType = [Type] "System.Collections.Generic.List``1" [type[]] $typedParameters = ,"System.String" $closedType = $genericType.MakeGenericType($typedParameters) [Activator]::CreateInstance($closedType) } $a = test The problem is that $a is always null no matter what I try. If I execute the same code outside of the function it works properly. Thoughts?

  • How do I get regex support in excel via a function, or custom function?

    - by blunders
    It appears that regex (as in regular expressions) is not supported in excel, except via VBA. Is this so, and is it is, are there any "open source" custom VBA functions that support regex. In this case I'm looking to extract complex pattern within a string, but any implementation of a custom VBA function that expose support of regex within the function itself would be of use. If you know of semi-related function such as the IS function, feel feel to comment, though I'm really looking for a full regular expression implementation that is exposed via functions. Might even be open to a pay to use add-in if the implementation is good. If you have questions, please comment.

  • boost test case for function taking user input

    - by oadams
    I have a function that takes in user input via std::cin: std::getline(std::cin, in); and creates a corresponding data structure by matching it with a regular expression. The function then returns this data structure. I'm using boost.test and I want to create a unit test to check that the output data type is correct given some inputs. However I don't know how to go about it since the input isn't passed as an argument to the function. EDIT: Is there a simple way to create a boost test case that feeds the function a string via standard input?

  • Passing javascript to a function

    - by AJ
    Hello, Can I pass some Javascript to a function and then execute that Javascript from within the function, e.g. test("a = 1; b = 2; test2(a,b);"); function test(js) { // execute dynamically generated JS here. } Basically I have some code that is generated on the server and I want to pass that code to a JS function which when it has finished processing it executes the code passed as a parameter. This could also be useful for the parameter of setTimeout, then the code passed could be executed in the timeout event. Can this be done?

  • PHP: constant as variable in function

    - by m4recek
    I'm trying to use constant as a function paramter, is it possible to check type of this constant. Example of what I want: class ApiError { const INVALID_REQUEST = 200; } class Response { public function status(ApiError $status) { //function code here } } USE: $response = new Response(); $response->status(ApiError::INVALID_REQUEST); This shoud check that given $status is constant of class ApiError. Is something like this possible?

  • Neural network for aproximation function for board game

    - by Pax0r
    I am trying to make a neural network for aproximation of some unkown function (for my neural network course). The problem is that this function has very many variables but many of them are not important (for example in [f(x,y,z) = x+y] z is not important). How could I design (and learn) network for this kind of problem? To be more specific the function is an evaluation function for some board game with unkown rules and I need to somehow learn this rules by experience of the agent. After each move the score is given to the agent so actually it needs to find how to get max score. I tried to pass the neighborhood of the agent to the network but there are too many variables which are not important for the score and agent is finding very local solutions.

  • to store char* from function return value

    - by samprat
    Hi folks, I am trying to implement a function which reads from Serial Port ( Linux) and retuns char*. The function works fine but how would I store return value from function. example of function is char *ReadToSerialPort() { char *bufptr; char buffer[256]; // Input buffer/ / //char *bufptr; // Current char in buffer // int nbytes; // Number of bytes read // bufptr = buffer; while ((nbytes = read(fd, bufptr, buffer+sizeof(buffer)-bufptr -1 )) > 0) { bufptr += nbytes; // if (bufptr[-1] == '\n' || bufptr[-1] == '\r') /*if ( bufptr[sizeof(buffer) -1] == '*' && bufptr[0] == '$' ) { break; }*/ } // while ends if ( nbytes ) return bufptr; else return 0; *bufptr = '\0'; } // end ReadAdrPort //In main int main( int argc , char *argv[]) { char *letter; if(strcpy(letter, ReadToSerialPort()) >0 ) { printf("Response is %s\n",letter); } }

  • Checking if a function has C-linkage at compile-time [unsolvable]

    - by scjohnno
    Is there any way to check if a given function is declared with C-linkage (that is, with extern "C") at compile-time? I am developing a plugin system. Each plugin can supply factory functions to the plugin-loading code. However, this has to be done via name (and subsequent use of GetProcAddress or dlsym). This requires that the functions be declared with C-linkage so as to prevent name-mangling. It would be nice to be able to throw a compiler error if the referred-to function is declared with C++-linkage (as opposed to finding out at runtime when a function with that name does not exist). Here's a simplified example of what I mean: extern "C" void my_func() { } void my_other_func() { } // Replace this struct with one that actually works template<typename T> struct is_c_linkage { static const bool value = true; }; template<typename T> void assertCLinkage(T *func) { static_assert(is_c_linkage<T>::value, "Supplied function does not have C-linkage"); } int main() { assertCLinkage(my_func); // Should compile assertCLinkage(my_other_func); // Should NOT compile } Is there a possible implementation of is_c_linkage that would throw a compiler error for the second function, but not the first? I'm not sure that it's possible (though it may exist as a compiler extension, which I'd still like to know of). Thanks.

  • 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?

  • Changing the context of a self-executing function

    - by TaylorMac
    This code is copied directly from: http://www.bennadel.com/blog/2264-Changing-The-Execution-Context-Of-Your-Self-Executing-Function-Blocks-In-JavaScript.htm // Set the singleton value to the return value of the self- // executing function block. var singleton = (function(){ // Declare a private variable. var message = "Stop playing with your context!"; this.getMessage = function(){ return( message ); }; // Return this object reference. return( this ); }).call( {} ); // alert the singleton message. alert( "Message:", singleton.getMessage()); ?My thought is that I can use this to better contain the variables and functions in my programs. However, when I try to run the code in a JSfiddle: http://jsfiddle.net/xSKHh/ It does not return the message. What am I missing?

  • Invoking a function of library libfprint in Python

    - by Ivanelson
    I need help to call a function(Struct C) that detects the devices, so I'm calling the function this way: from ctypes import * fp = CDLL('./libfprint.so.0') fp.fp_discover_devs.argtypes = None fp.fp_discover_devs.restype = c_char_p ret = fp.fp_discover_devs() print ret # is "0" That is not detected any device, because the return is "0". See the documentation of the function: I'm using Ubuntu and I downloaded the "fprint_demo" and works perfectly. Did you install any package missing? Thanks.

  • start javascript code with $(function, etc

    - by YAmikep
    I am studying Backbone and the todo example apps from http://todomvc.com/ I have noticed there are 3 severals ways of starting the code in the files: $(function() { // code here }); $(function( $ ) { // code here }); (function() { // code here }()); I do not understand the differences and when I should use one over the other. I also saw some people using this to start their code: $(document).ready(function(){ // code here }); From what I have seen, this is the full way of writing it right? In a more general way, should I always include my javascript code into something like that in each files? Thanks for your advice.
