  • Assign parameters to function according to parameter names

    - by Korcholis
    I have an assoc array with a list of what are parameters to me. Here's an example: array( 'param1' => 'value1', 'param4' => 'value4', 'param3' => 'value3', 'param2' => 'value2', ); Note that they may come unsorted. Now, is there a way I can make a call (static or from an instance, using call_user_func_array or similar) and correctly pass each value to each parameter? Just to be sure, an example function I'd like to call using that parameter array is one such this: exampleFunction($param1, $param2, $param3, $param4) { ... } PS: Reflection is great, but I'm concerned about execution times (which, at least, in Java tends to increase a lot when using Reflection). If you know any other way to do so, it would be awesome.

  • Lua not producing table of functions (IO API)

    - by ArtOfCode
    I'm working on a basic project in Lua. I've been trying to get data from files using the IO API (as defined here), but when I open a file and give it a handle, it doesn't seem to return a table of functions. The (erroneous bit of) code: local unread = fs.list("email/"..from.."/") local send = "" for _,file in ipairs(unread) do local handle = io.open(file,"r") local text = handle:read("*a") send = send .. text .. "\n" handle.close() fs.delete(file) end The fs you see on the first line is a professional filesystem wrapper round the IO API, not my work and perfectly error-free, so that's not the problem. However, when I try to read the file (handle:read()), it throws "attempt to index nil". Tracing it, it turns out that handle itself is nil. Any ideas?

  • Returning string in java using 3 parameters

    - by user2905118
    Need to write a method describePerson() that takes 3 parameters, a String giving a person’s name, a boolean indicating their gender (true for female, false for male), and an integer giving their age. The method should return a String formatted as in the following examples: Lark is female. She is 2 years old. Or Jay is male. He is 1 year old. I am not sure how to write it correctly (my code): int describePerson(String name, boolean gender, int age) { String words=""; if(gender==true) return (name + "is "+gender+". "+"She is"+age+ "years old.); else return (name + "is "+gender+". "+"She is"+age+ "years old.); } The outcome "year" and "years" is also differs, but i don't know how to make it correct..

  • Junit | How to test parameters in a method

    - by MMRUser
    How do I test parameters inside a method itself. For example class TestClass { public void paraMethod(String para1, String para2) { String testPara1 = para1; String testPara2 = para2; } } class TestingClass { @Test public void testParaMethod () throws Exception { String myPara1 = "MyPara1"; String myPara2 = "MyPara2"; new TestClass().paraMethod(myPara1, myPara2); } } Ok, so is it possible to test if the testPara1 and testPara2 are properly set to the values that I have passed? Thanks.

  • PHP parameter without value using for navigation

    - by somewalri
    Hello, I am trying to set up a navigation system that uses GET parameters with no value, example: http://foo.bar/?mainPage takes the visitor to the main page. So I am using if statements and I am wondering if there is a way I can do this without a bunch of if statements? I don't think switch statements would work for this. This is currently what I have: $mainPage = $_GET['mainPage']; $contact = $_GET['contact']; if(isset($mainPage)) { // go to main page } if(isset($contact)) { // go to contact page } I don't want to have to end up writing a ton of if statements, though. Any ideas? Thanks.

  • Hitting a Button -> Executing any class function I give it in the parameters (C++)

    - by Barnes Noble
    Can anyone help me with class function parameter callbacks? I'm not so sure how to set it up in my code here: http://codepad.org/fvwHtDjQ Basically I've got a player and an enemy. I have two buttons. One button when clicked should let the player jump. The other should make the enemy hit something. When clicked, each button has to correspond to the class function in the parameters. I'm not sure how to set it up though.

  • JQuery .get() only passing first two data parameters in url

    - by The.Anti.9
    I have a $.get() call to a PHP page that takes 4 GET parameters. For some reason, despite giving the $.get() call all 4, it only passes the first two. When I look at the dev console in chrome, it shows the URL that gets called, and it only passes action and dbname. Heres the code: $.get('util/util.php', { action: 'start', dbname: db, url: starturl, crawldepth: depth }, function(data) { if (data == 'true') { status = 1; $('#0').append(starturl + "<ul></ul>"); $('#gobutton').hide(); $('#loading').show("slow"); while(status == 1) { setTimeout("update()",10000); } } else { show_error("Form data incomplete!"); } }); and heres the URL that I see in the developer console: http://localhost/pci/util/util.php?action=start&dbname=1hkxorr9ve1kuap2.db

  • Find and list all functions/methods in a set of JavaScript files

    - by Dan Milstein
    Is there a way to read a set of JavaScript files, and output a description of where every function/method is defined? I realize that this is likely impossible in full generality, due to the extreme dynamic nature of the language. What I'm imagining is something which gets the (relatively) straightforward cases. Ideally, I'd want it figure out where, e.g. some method got attached to string or hash or some other fundamental class (and also just let you find all the classes/functions that get defined once in one place). Does such a tool exist?

  • Automatic conversion between methods and functions in Scala

    - by fikovnik
    I would like to understand the rules when can Scala automatically convert methods into functions. For example, if I have following two methods: def d1(a: Int, b: Int) {} def r[A, B](delegate: (A, B) ? Unit) {} I can do this: r(d1) But, when overloading r it will no longer work: def r[A, B, C](delegate: (A, B, C) ? Unit) {} r(d1) // no longer compiles and I have to explicitly convert method into partially applied function: r(d1 _) Is there any way to accomplish following with the explicit conversion? def r[A, B](delegate: (A, B) ? Unit) {} def r[A, B, C](delegate: (A, B, C) ? Unit) {} def d1(a: Int, b: Int) {} def d2(a: Int, b: Int, c: Int) {} r(d1) // only compiles with r(d1 _) r(d2) // only compiles with r(d2 _) There is somewhat similar question, but it is not fully explained.

  • Create a class that inherets DrawableGameComponent in XNA as a CLASS with custom functions

    - by user3675013
    using Microsoft.Xna.Framework.Graphics; using Microsoft.Xna.Framework.Media; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Content; namespace TileEngine { class Renderer : DrawableGameComponent { public Renderer(Game game) : base(game) { } SpriteBatch spriteBatch ; protected override void LoadContent() { base.LoadContent(); } public override void Draw(GameTime gameTime) { base.Draw(gameTime); } public override void Update(GameTime gameTime) { base.Update(gameTime); } public override void Initialize() { base.Initialize(); } public RenderTarget2D new_texture(int width, int height) { Texture2D TEX = new Texture2D(GraphicsDevice, width, height); //create the texture to render to RenderTarget2D Mine = new RenderTarget2D(GraphicsDevice, width, height); GraphicsDevice.SetRenderTarget(Mine); //set the render device to the reference provided //maybe base.draw can be used with spritebatch. Idk. We'll see if the order of operation //works out. Wish I could call base.draw here. return Mine; //I'm hoping that this returns the same instance and not a copy. } public void draw_texture(int width, int height, RenderTarget2D Mine) { GraphicsDevice.SetRenderTarget(null); //Set the renderer to render to the backbuffer again Rectangle drawrect = new Rectangle(0, 0, width, height); //Set the rendering size to what we want spriteBatch.Begin(); //This uses spritebatch to draw the texture directly to the screen spriteBatch.Draw(Mine, drawrect, Color.White); //This uses the color white spriteBatch.End(); //ends the spritebatch //Call base.draw after this since it doesn't seem to recognize inside the function //maybe base.draw can be used with spritebatch. Idk. We'll see if the order of operation //works out. Wish I could call base.draw here. } } } I solved a previous issue where I wasn't allowed to access GraphicsDevice outside the main Default 'main' class Ie "Game" or "Game1" etc. Now I have a new issue. FYi no one told me that it would be possible to use GraphicsDevice References to cause it to not be null by using the drawable class. (hopefully after this last bug is solved it doesn't still return null) Anyways at present the problem is that I can't seem to get it to initialize as an instance in my main program. Ie Renderer tileClipping; and I'm unable to use it such as it is to be noted i haven't even gotten to testing these two steps below but before it compiled but when those functions of this class were called it complained that it can't render to a null device. Which meant that the device wasn't being initialized. I had no idea why. It took me hours to google this. I finally figured out the words I needed.. which were "do my rendering in XNA in a seperate class" now I haven't used the addcomponent function because I don't want it to only run these functions automatically and I want to be able to call the custom ones. In a nutshell what I want is: *access to rendering targets and graphics device OUTSIDE default class *passing of Rendertarget2D (which contain textures and textures should automatically be passed with a rendering target? ) *the device should be passed to this function as well OR the device should be passed to this function as a byproduct of passing the rendertarget (which is automatically associated with the render device it was given originally) *I'm assuming I'm dealing with abstracted pointers here so when I pass a class object or instance, I should be recieving the SAME object , I referenced, and not a copy that has only the lifespan of the function running. *the purpose for all these options: I want to initialize new 2d textures on the fly to customize tileclipping and even the X , y Offsets of where a WHOLE texture will be rendered, and the X and Y offsets of where tiles will be rendered ON that surface. This is why. And I'll be doing region based lighting effects per tile or even per 8X8 pixel spaces.. we'll see I'll also be doing sprite rotations on the whole texture then copying it again to a circular masked texture, and then doing a second copy for only solid tiles for masked rotated collisions on sprites. I'll be checking the masked pixels for my collision, and using raycasting possibly to check for collisions on those areas. The sprite will stay in the center, when this rotation happens. Here is a detailed diagram: http://i.stack.imgur.com/INf9K.gif I'll be using texture2D for steps 4-6 I suppose for steps 1 as well. Now ontop of that, the clipping size (IE the sqaure rendered) will be able to be shrunk or increased, on a per frame basis Therefore I can't use the same static size for my main texture2d and I can't use just the backbuffer Or we get the annoying flicker. Also I will have multiple instances of the renderer class so that I can freely pass textures around as if they are playing cards (in a sense) layering them ontop of eachother, cropping them how i want and such. and then using spritebatch to simply draw them at the locations I want. Hopefully this makes sense, and yes I will be planning on using alpha blending but only after all tiles have been drawn.. The masked collision is important and Yes I am avoiding using math on the tile rendering and instead resorting to image manipulation in video memory which is WHY I need this to work the way I'm intending it to work and not in the default way that XNA seems to handle graphics. Thanks to anyone willing to help. I hate the code form offered, because then I have to rely on static presence of an update function. What if I want to kill that update function or that object, but have it in memory, but just have it temporarily inactive? I'm making the assumption here the update function of one of these gamecomponents is automatic ? Anyways this is as detailed as I can make this post hopefully someone can help me solve the issue. Instead of tell me "derrr don't do it this wayyy" which is what a few people told me (but they don't understand the actual goal I have in mind) I'm trying to create basically a library where I can copy images freely no matter the size, i just have to specify the size in the function then as long as a reference to that object exists it should be kept alive? right? :/ anyways.. Anything else? I Don't know. I understand object oriented coding but I don't understand this XNA It's beggining to feel impossible to do anything custom in it without putting ALL my rendering code into the draw function of the main class tileClipping.new_texture(GraphicsDevice, width, height) tileClipping.Draw_texture(...)

  • Text editor with coloring to highlight "non-parameters" in conf files?

    - by Zabba
    Some .conf files have a lot of comments and parameters in them like so: # WINS Server - Tells the NMBD components of Samba to be a WINS Client # Note: Samba can be either a WINS Server, or a WINS Client, but NOT both ; wins server = w.x.y.z # This will prevent nmbd to search for NetBIOS names through DNS. dns proxy = no ..... It gets difficult to look for only the parameters among the plethora of comments, so, is there some text editor that can highlight the comments in dark grey so that the real parameters stand out?

  • Include in service layer all the application's functions or only the reusable ones?

    - by BornToCode
    Background: I need to build a main application with some operations (CRUD and more) (-in winforms), I need to make another application which will re-use some of the functions of the main application (-in webforms). I understood that using service layer is the best approach here. If I understood correctly the service should be calling the function on the BL layer (correct me if I'm wrong) The dilemma: In my main winform UI - should I call the functions from the BL, or from the service? (please explain why) Should I create a service for every single function on the BL even if I need some of the functions only in one UI? for example - should I create services for all the CRUD operations, even though I need to re-use only update operation in the webform? YOUR HELP IS MUCH APPRECIATED

  • Sharepoint - Passing parameters in URL to NewForm.aspx

    Any suggestions would be great. I've inherited a system and have been requested to add a context menu item to allow the ability to add a new item. I've set up the context menu with the new option and the newform.aspx to accept and pull parameters from the url for populating some fields. The context menu was created with the content editor web part and the follow JavaScript. function Custom_AddDocLibMenuItems(m, ctx) { var strAction = "window.location='http://address?para1=....'"; var strDisplayText = "Taxonomy"; var strImagePath = ""; // Add our new menu item CAMOpt(m, strDisplayText, strAction, strImagePath); // add a separator to the menu CAMSep(m); // false means that the standard menu items should also be rendered return false; } I'm having difficulties getting the proper values in order to concatenate them to the strAction string (which would be the full url of the newform.aspx. Any suggestions on how I retrieve the values of the columns for the item that the user right click to get context menu.

  • SSRS 2005 - Cascading parameters and default value update problem

    - by sHr0oMaN
    I have a report with cascading parameters. The first parameter is Finanical Period Type, being either Month or Week. The second parameter is a list of either financial months or weeks depending on what was selected for the first parameter. This all works well and selecting a series of different Financial Period Types in sequence correctly updates the second parameter's values. However I now wish to add a default value for the second parameter, which is once again dependent on the first parameter. So I've added an additional field to the dataset populating the second parameter called DefaultPeriod and set the second parameter's default value to be retrieved from the above field. The first time I select the Financial Period Type, the default is correctly set. However changing the Financial Period Type results in an updated list for the second parameter, but the default is incorrect. It remains set to the original default value, even thought the dataset has been refresh and the DefaultPeriod field is correct. This is both an issue in the IDE and on the Report Manager site.

  • Call functions in AutoIt DLL using Python ctypes

    - by Josh
    I want to call functions from an AutoIt dll, that I found at C:\Program Files (x86)\AutoIt3\AutoItX\AutoItX3.dll using Python. I know I could use win32com.client.Dispatch("AutoItX3.Control") but I can't install the application or register anything in the system. So far, this is where I am: from ctypes import * path = r"C:\Program Files (x86)\AutoIt3\AutoItX\AutoItX3.dll" autoit = windll.LoadLibrary(path) Here are the methods that works: autoit.AU3_WinMinimizeAll() # windows were successfully minimized. autoit.AU3_Sleep(1000) # sleeps 1 sec. Here is my problem, python is crashing when I call other methods like this one. I get python.exe has stopped working from windows... autoit.AU3_WinGetHandle('Untitled - Notepad', '') And some other methods are not crashing python but are just not working. This one doesn't close the window and return 0: autoit.AU3_WinClose('Untitled - Notepad', '') And this other one return 1 but the window is still minimized: autoit.AU3_WinActivate('Untitled - Notepad', '') I've tested the examples with with Dispatch("AutoItX3.Control") and everything is working like expected. It seems like methods that should return something other than a string are crashing python. But still, others like WinClose are not even working... Thank you in advance for your help! EDIT: These methods are now working when using unicode strings: autoit.AU3_WinClose(u'Untitled - Notepad', u'') autoit.AU3_WinActivate(u'Untitled - Notepad', u'') And I found the prototype for AU3_WinGetHandle: AU3_API void WINAPI AU3_WinGetHandle(const char szTitle, /[in,defaultvalue("")]*/const char *szText, char *szRetText, int nBufSize); Now I see that I should get the handle from szRetText but I am not sure how... I tried the following without success: from ctypes.wintypes import LPCWSTR, INT, POINTER AU3_WinGetHandle.argtypes = (LPCWSTR, LPCWSTR, POINTER(LPCWSTR), INT) s = c_wchar_p() print AU3_WinGetHandle(u'Untitled - Notepad', u'', byref(s), 100) # prints 1 print s # prints c_wchar_p(u'') Any idea how to retrive the handle from szRetText?

  • Invoking WCF functions using Reflection

    - by Jankhana
    I am pretty new to WCF applications. I have a WCF application that is using NetTcpBinding. I wanted to invoke the functions in WCF service using the System.Reflection's Methodbase Invoke method. I mean I wanted to Dynamically call the Function by passing the String as the Function name. Reflection works great for Web Service or a Windows application or any dll or class. So their is certain way to do this for WCF also but I am not able to find that. I am getting the Assembly Name than it's type everything fine but as we cannot create an instance of the Interface class I tried to open the WCF connection using the binding and tried to pass that object but it's throwing the exception as : "Object does not match target type." I have opened the connection and passed the object and type is of interface only. I don't know whether I'm trying wrong thing or in wrong way. Any idea how shall I accomplish this??? The NetTCPBinding all are properly given while opening the connection. And one more thing I am using WCF as a Windows Service using NETTCPBinding.

  • Missing functions in ruby 1.8

    - by Adrian
    I have a ruby gem that I developed with ruby 1.9, and it works. With ruby 1.8, though, it says this when I try to run it: dyld: lazy symbol binding failed: Symbol not found: _RBIGNUM_SIGN Referenced from: /Users/Adrian/Desktop/num_to_bytes/ext/num_to_bytes/num_to_bytes.bundle Expected in: flat namespace dyld: Symbol not found: _RBIGNUM_SIGN Referenced from: /Users/Adrian/Desktop/num_to_bytes/ext/num_to_bytes/num_to_bytes.bundle Expected in: flat namespace Trace/BPT trap If I comment out the line that uses RBIGNUM_SIGN, it complains about other functions like rb_big_modulo. Some things work, like NUM2LONG. Here are some things I have tried: In http://github.com/ruby/ruby/blob/ruby_1_8_7/ruby.h, RBIGNUM_SIGN is defined. But in all versions of ruby I have tried, it is not there. I guessed that maybe it was defined in a different .h file. Knowing that Hpricot works with 1.8, I looked at http://github.com/hpricot/hpricot/blob/master/ext/hpricot_scan/hpricot_scan.h. It doesn't include any other files that #define it. Putting things like extern VALUE rb_big_modulo(VALUE x); at the beginning of my extension don't help. Using a brand new Ubuntu installation, I apt-getted ruby, tried to install the gem, and it didn't work either. Putting have_library 'ruby', 'rb_big_modulo' in my extconf.rb didn't work. As you can probably see, I am getting desperate (after weeks of trying things!). So, how can I get this to work? Here is the gem: http://rubygems.org/gems/num_to_bytes Here is the source: http://gist.github.com/404584

  • Nested Routes and Parameters for Rails URLs (Best Practice)

    Hey there, I have a decent understanding of RESTful urls and all the theory behind not nesting urls, but I'm still not quite sure how this looks in an enterprise application, like something like Amazon, StackOverflow, or Google... Google has urls like this: http://code.google.com/apis/ajax/ http://code.google.com/apis/maps/documentation/staticmaps/ https://www.google.com/calendar/render?tab=mc Amazon like this: http://www.amazon.com/books-used-books-textbooks/b/ref=sa_menu_bo0?ie=UTF8&node=283155&pf_rd_p=328655101&pf_rd_s=left-nav-1&pf_rd_t=101&pf_rd_i=507846&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=1PK4ZKN4YWJJ9B86ANC9 http://www.amazon.com/Ruby-Programming-Language-David-Flanagan/dp/0596516177/ref=sr_1_1?ie=UTF8&s=books&qid=1258755625&sr=1-1 And StackOverflow like this: http://stackoverflow.com/users/169992/viatropos http://stackoverflow.com/questions/tagged/html http://stackoverflow.com/questions/tagged?tagnames=html&sort=newest&pagesize=15 So my question is, what is best practice in terms of creating urls for systems like these? When do you start storing parameters in the url, when don't you? These big companies don't seem to be following the rules so hotly debated in the ruby community (that you should almost never nest URLs for example), so I'm wondering how you go about implementing your own urls in larger scale projects because it seems like the idea of not nesting urls breaks down at anything larger than a blog. Any tips?

  • Django: Complex filter parameters or...?

    - by minder
    This question is connected to my other question but I changed the logic a bit. I have models like this: from django.contrib.auth.models import Group class Category(models.Model): (...) editors = ForeignKey(Group) class Entry(models.Model): (...) category = ForeignKey(Category) Now let's say User logs into admin panel and wants to change an Entry. How do I limit the list of Entries only to those, he has the right to edit? I mean: How can I list only those Entries which are assigned to a Category that in its "editors" field has one of the groups the User belongs to? What if User belongs to several groups? I still need to show all relevant Entries. I tried experimenting with changelist_view() and queryset() methods but this problem is a bit too complex for me. I'm also wondering if granular-permissions could help me with the task, but for now I have no clue. I came up only with this: First I get the list of all Groups the User belongs to. Then for each Group I get all connected Categories and then for each Category I get all Entries that belong to these Categories. Unfortunately I have no idea how to stitch everything together as filter() parameters to produce a nice single QuerySet.
