  • Getting PDT code completion to recognise runtime return types from base class?

    - by Keith Humm
    Hi guys, I've got an abstract base class: abstract class BaseClass { /** * @return CLASSNAME */ public function fluent() { // do stuff return $this; } } Generally, i would put BaseClass where CLASSNAME is and all would be fine, PDT would pick up the phpdoc return type and happily autocomplete. Until, that is, I subclass BaseClass and add additional methods, and code compete on an instance of the derived class. PDT will only recognise the methods from BaseClass and not those from the derived class. What I need is something like @return self or @return this. Does PDT have such functionality? Or is there an alternate trick without having to declare these methods in every derived class?

  • inheritance and hidden overloads

    - by Caspin
    The following code doesn't compile. struct A {}; struct B {}; class Base { public: virtual void method( A param ) { } virtual void method( B param ) = 0; }; class Derived : public Base { public: //using Base::method; void method( B param ) { } }; int main() { Derived derived; derived.method(A()); } The compiler can't find the overload of method() that has an A parameter. The 'fix' is to add a using declaration in the derived class. My question is why. What is the rational for a weird language rule like this? I verified the error in both GCC and Comeau, so I assume this isn't a compiler bug but a feature of the language. Comeau at least gives me this warning: "ComeauTest.c", line 10: warning: overloaded virtual function "Base::method" is only partially overridden in class "Derived" class Derived : public Base ^

  • OO design for business logic

    - by hotyi
    I have one Sell Operation object and two Buy Operation objects, i want to implement such behavior that one Sell Operation discharges two Buy Operation, it looks like: sellOperation.Discharge(oneBuyOperation); sellOperation.Discharge(twoBuyOperation); so i want to ask whether i should call the repository function in the Discharge method, or i'd better call the repository save method outside Discharge method. like: opRepository.Save(sellOpertion); So anyone could give me some advise what are you going to implement in this scenario? using Service class or anything better way?

  • Rendering a variable with erb.

    - by TZer0
    I've got the following problem: I have rhtml (html minced together with ruby inside <% % and <%= % tags) stored in a database which I want to render. The information is acquired through a query. I need to be able to evaluate the information I get from the database as though as it was normal content inside the .erb-file. What I currently have: <% @mymods.each do |mod| %> <%= render_text(mod["html"])%> <% end %> Where mod["html"] is the variable containing the rhtml-code and @mymods an array of objects from the query. I have currently no idea what function I should use (render_text does, of course, not work). Help is greatly appreciated. /TZer0

  • Add remove class?

    - by Steven
    Okay I have two classes for two links and two divs with different information. What I am trying to do is have it so when you click on one link it adds a 2 to both of the classes and makes the second div visable. When you click on the other link it takes off a 2 and makes the first div visable. Here is what I currently got $("#posts").click(function () { $("#sideboxtopleft").toggleClass("2"); $("#arrow").toggleClass("2"); }); Pretty much posts is the link, when when you click on it. It would make sideboxtopleft and arrow, sideboxtopleft2 and arrow2 and when you clicked on comments it would take off the 2 of both of those. Then there are two divs, one is set to hidden and I want to make it visable and set the other to hidden. Pretty much creating a tab system with changing tab classes.

  • How to return 'null' instead of 'undefined' from select element

    - by MrW
    How can I return null instead of a 'undefined' from a select element. Basically I have 4 selects at the moment, but only the first one is populated with data at this point, but I want to grab the value from all of them when working with them. <select class="changeValue" id="drpOne"></select> <option id=1>1</option> <option id=2>2</option> <option id=3>3</option> <select class="changeValue" id="drpTwo"></select> JQuery: $('.changeValue').change(function() { var data = {}; data["Id1"] = $('#drpOne:selected').attr("id"); data["Id2"] = $('#drpTwo:selected').attr("id"); In this case, drpTwo will return 'undefined'. Is there anyway to get a null instead?

  • Providing SaaS functionality to a .NET portal with DLLs

    - by Abdullah Jibaly
    I'm not sure I'm asking the right question here, but I'm looking to provide web based functionality from one ASP.NET application to another remote 'portal-like' application. Is it possible to simply give the portal a DLL? As an example, let's say the SaaS web app has a patient-entry form that I want to be able to use from the portal application. I would like the portal app to be able to set preferences (permissions, color, style, etc), make a function call, and have that capability presented within a certain div or something. Is there any .NET technologies that provide this kind of integration?

  • A hooked DirectX 9 program crashes on window resize, texture related.

    - by Ben
    I'm using EasyHook and SlimDX to overlay some graphics using SlimDX's Sprite and Texture classes. When I resize windows some programs fine, but others will crash - Winamp's MilkDrop 2 gives me an ambiguous memory error for example. I expect this is due to the after market Texture I created. The question is what VTable function should I hook and/or how/when do I dispose and recreate the Texture? Reset perhaps? If it isn't obvious I don't know much about DirectX.

  • javascript literal initialisation loop

    - by graham.reeds
    I have an object which has several properties that are set when the object is created. This object recently changed to object literal notation, but I've hit a bit of a problem that searching on the net doesn't reveal. Simply stated I need to do this: Star = function(_id, _x, _y, _n, _o, _im, _c, _b, _links) { var self = { id: _id, // other properties links: [], for (var i=0,j=0;i<8;i++) { //<- doesn't like this line var k = parseInt(_links[i]); if (k > 0) { this.links[j++] = k; } }, // other methods }; return self; }; How do I initialise a property in the constructor in object literal notation?

  • Question regarding inheritance in wxWidgets.

    - by celestialorb
    Currently I'm attempting to write my own wxObject, and I would like for the class to be based off of the wxTextCtrl class. Currently this is what I have: class CommandTextCtrl : public wxTextCtrl { public: void OnKey(wxKeyEvent& event); private: DECLARE_EVENT_TABLE() }; Then later on I have this line of code, which is doesn't like: CommandTextCtrl *ctrl = new CommandTextCtrl(panel, wxID_ANY, *placeholder, *origin, *size); ...and when I attempt to compile the program I receive this error: error: no matching function for call to ‘CommandTextCtrl::CommandTextCtrl(wxPanel*&, <anonymous enum>, const wxString&, const wxPoint&, const wxSize&)’ It seems that it doesn't inherit the constructor method with wxTextCtrl. Does anyone happen to know why it doesn't inherit the constructor? Thanks in advance for any help!

  • Issue with maxWorkerThreads and thread count

    - by Kartik M
    I have created an ASP.NET application which creates threads in an infinite loop. I set maxWorkerThreads to 20 in processModel in machine.config. When I checked the Thread count in perfmon there was around 7000 threads created in worker process. In PageLoad() I have: using System.Threading; ... int count = 0; var threadList = new System.Collections.Generic.List<System.Threading.Thread>(); try { while (true) { Thread newThread = new Thread(ThreadStart(DummyCall), 1024); newThread.Start(); threadList.Add(newThread); count++; } } catch (Exception ex) { Response.Write(count + " : " + ex.ToString()); } Function: void DummyCall() { System.Threading.Thread.Sleep(1000000000); } How do I restrict thread creation in ASP.NET with IIS6/7?

  • Adding an ActionScript eventListener that takes the whole sprite

    - by Rudy
    Hello, I have a very simple constructor in ActionScript as the following: public function ButtonTest() { this.addEventListener(MouseEvent.CLICK, browseFiles); } My problem is that when I open the SWF file itself, the window is not full size and the whole area responds to the mouse click. If I expand the window to full size, a margin of like 200 pixels on the left is not clickable. I hope I make some sense. The issue is that I had the .SWF file in a in my HTML code, and when I make it small, it seems that only the center of the SWF file is clickable. I hope someone can please help me. Thank you, Rudy

  • Exactly clone an object in javascript

    - by Tom
    Hi, I tried to exactly clone an object in javascript. I know the following solution using jquery: var newObject = jQuery.extend({}, oldObject); // Or var newObject = jQuery.extend(true, {}, oldObject); but the problem with that is, that the objects type gets lost: var MyClass = function(param1, param2) { alert(param1.a + param2.a); }; var myObj = new MyClass({a: 1},{a: 2}); var myObjClone = jQuery.extend(true, {}, myObj); alert(myObj instanceof MyClass); // => true alert(myObjClone instanceof MyClass); // => false Is there any solution to get true on the second alert?

  • Linux / C++: Get the IP Address of local computer

    - by BlaM
    This Question is almost the same as the previously asked Get the IP Address of local computer-Question. However I need to find the IP address(es) of a Linux Machine. So: How do I - programmatically in C++ - detect the IP addresses of the linux server my application is running on. The servers will have at least two IP addresses and I need a specific one (the one in a given network (the public one)). I'm sure there is a simple function to do that - but where? [EDIT] To make things a bit clearer: The server will obviously have the "localhost": 127.0.0.1 The server will have an internal (management) IP address: 172.16.x.x The server will have an external (public) IP address: 80.190.x.x I need to find the external IP address to bind my application to it. Obviously I can also bind to INADDR_ANY (and actually that's what I do at the moment). I would prefer to detect the public address, though.

  • Convert Eregi_replace to preg_replace in PHP

    - by alexy13
    I need help converting eregi_replace to preg_replace (since in PHP5 it's depreciated): function makeClickableLinks($text) { $text = eregi_replace('(((f|ht){1}tp://)[-a-zA-Z0-9@:%_\+.~#?&//=]+)', '<a href="\\1">\\1</a>', $text); $text = eregi_replace('([[:space:]()[{}])(www.[-a-zA-Z0-9@:%_\+.~#?&//=]+)', '\\1<a href="http://\\2">\\2</a>', $text); $text = eregi_replace('([_\.0-9a-z-]+@([0-9a-z][0-9a-z-]+\.)+[a-z]{2,3})', '<a href="mailto:\\1">\\1</a>', $text); return $text; } (It turns text links and emails into hyperlinks so that the user can click on them)

  • Show javascript execution progress

    - by Midhat
    I have some javascript functions that take about 1 to 3 seconds. (some loops or mooML templating code.) During this time, the browser is just frozen. I tried showing a "loading" animation (gif image) before starting the operation and hiding it afterwords. but it just doesnt work. The browser freezes before it could render the image and hides it immediately when the function ends. Is there anything I can do to tell the browser to update the screen before going into javascript execution., Something like Application.DoEvents or background worker threads. So any comments/suggestions about how to show javascript execution progress. My primary target browser is IE6, but should also work on all latest browsers

  • rails: date type and GetDate

    - by cbrulak
    This is a follow up to this question: http://stackoverflow.com/questions/2930256/unique-responses-rails-gem I'm going to create an index based on the user id, url and a date type. I want date type (not datetime type) because I want the day, the 24 hour day to be part of the index to avoid duplication of page views counts on the same day. In other words: A view only counts once in a day by a visitor. I also want the default value of that column (viewdate) to be the function GETDATE(). This is what I have in my migration: execute "ALTER TABLEpage_viewsADD COLUMN viewdate datetime DEFAULTGETDATE()`" But the value viewdate is always empty. What am I missing? (as an aside, any other suggestions for accomplishing this goal?)

  • Why am I getting "Enter Parameter Value" when running my MS Access query?

    - by DanM
    In my query, I use the IIF function to assign either "Before" or "After" to a field named BeforeOrAfter using AS. When I run this query, however, the "Enter Parameter Value" dialog appears, requesting a value for BeforeOrAfter. If I remove BeforeOrAfter DESC from the ORDER BY clause, I don't get the dialog. Here is the offending query: SELECT d.Scenario, e.Event, IIF(d.LogTime < e.Time, 'Before','After') AS BeforeOrAfter, d.HeartRate FROM Data d INNER JOIN Events e ON d.Scenario = e.Scenario WHERE e.Include = Yes ORDER BY d.Scenario, e.Id, BeforeOrAfter DESC Question: Why is my AS BeforeOrAfter not being recognized by the ORDER BY clause? Why does it ask me to enter a parameter value for "BeforeOrAfter" when I run this query? Note: I tried using brackets, single quotes, double quotes, etc., but none of that made any difference.

  • Why does Excel expose an 'Evaluate' method at all?

    - by jtolle
    A few questions have come up recently involving the Application.Evaluate method callable from Excel VBA. The old XLM macro language also exposes an EVALUATE() function. Both can be quite useful. Does anyone know why the general expression evaluator is exposed, though? My own hunch is that Excel needed to give people a way to get ranges from string addresses, and to get the value of named formulas, and just opening a portal to the expression evaluator was the easiest way. But of course you don't need the ability to evaluate arbitrary expressions just to do that. Application.Evaluate seems kind of...unfinished. It isn't very well documented, and there are quite a few quirks and limitations (as described by Charles Williams here: http://www.decisionmodels.com/calcsecretsh.htm) with what is exposed. I suppose the answer could be simply "why not expose it?", but I'd be interested to know what design decisions led to this feature. Failing that, I'd be interested to hear other hunches.

  • UILabel: Using the userInteractionEnabled method on a label

    - by Kevin Bomberry
    Hello again. I am wondering if anyone has used the userInteractionEnabled method on a UILabel to allow the label to act like a button (or just to fire off a method). Any help would be greatly appreciated. Cheers! Update (4/30/09 @1:07pm) Clarification: I have a standard InfoButton and next to it I want to place a label with the text "settings" and I would like the label to function like the button (which flips over to a settings screen. So, basically I need to tie the already defined showSettinsView to the "infoLabel" label; a user clicks on the infoButton or infoLabel and the method fires off. The infoButton is already working and is using an IBAction to trigger the method. I would like to know how to wire up the label to implement the same method. That is all. Cheers!

  • const TypedeffedIntPointer not equal to const int *

    - by dirk
    I have the following C++ code: typedef int* IntPtr; const int* cip = new int; const IntPtr ctip4 = cip; I compile this with Visual Studio 2008 and get the following error: error C2440: 'initializing' : cannot convert from 'const int *' to 'const IntPtr' Clearly my understanding of typedefs is not what is should be. The reason I'm asking, I'm storing a pointer type in a STL map. I have a function that returns a const pointer which I would like to use to search in the map (using map::find(const key_type&). Since const MyType* and const map<MyType*, somedata>::key_type is incompatible, I'm having problems. Regards Dirk

  • Variadic functions and arguments assignment in C/C++

    - by Rizo
    I was wondering if in C/C++ language it is possible to pass arguments to function in key-value form. For example in python you can do: def some_function(arg0 = "default_value", arg1): # (...) value1 = "passed_value" some_function(arg1 = value1) So the alternative code in C could look like this: void some_function(char *arg0 = "default_value", char *arg1) { ; } int main() { char *value1 = "passed_value"; some_function(arg1 = value1); return(0); } So the arguments to use in some_function would be: arg0 = "default_value" arg1 = "passed_value" Any ideas?
