The use case is the following: Given a (fixed, not changeable) DLL implemented in C Wanted: a wrapper to this DLL implemented in python (chosen method: ctypes) Some of the functions in the DLL need synchronization primitives. To aim for maximum flexibility, the designers of the DLL completely rely on client-provided callbacks. More p...
I'm working on writing a tweening class in as2 that has a callback variable and I can't seem to find a good way to get the scope without specifically passing in a scope variable as well. This tweening class needs to work in classes as well as on the timeline. Here's what my codes looks like right now. params.scope[ params.onComplete ]( ...
I'm working on my first Android project, and I created a menu via the XML method. My activity is pretty basic, in that it loads the main layout (containing a ListView with my String array of options). Here's the code inside my Activity: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentV...
Suppose we have the standard Post & Comment models, with Post having accepts_nested_attributes_for :commments and :autosave => true set. We can create a new post together with some new comments, e.g.: @post = Post.new :subject => 'foo' @post.comments.build :text => 'bar' @post.comments.first # returns the new comment 'bar' @post.commen...
Hi. I have a big problem. I know it's about callback, closure but I don't know how to solve the problem. Here is my code $.Model.extend('Article', { findAll : function(params, success, error){ var result = [] db.transaction(function(tx) { tx.executeSql('select * fr...
I'm writing an (unmanaged) C++ class to wrap the Windows PropertySheet. Essentially, something like this: class PropSheet { PROPSHEETHEADER d_header; public: PropSheet(/* parameters */); INT_PTR show(); private: static int CALLBACK *propSheetProc(HWND hwnd, UINT msg, LPARAM lParam); }; The constructor just i...
I have been trying to write a delegate to a view controller which has a method which will call back the sender when it is done -(void) doSomething:(id)target action:(SEL)action object:(id)object{ //Do Some work //Produce an NSArray* called array object = array; if([target respondsToSelector:action]) { [target action]; ...
Hello all, We are creating a system in Ruby on Rails and we want to be able to offer our users a bit of control about notifications and actions that can take place when some pre-defined trigger occurs. In addition, we plan on iterating through imported data and allowing our users to configure some actions and triggers based on that data...
I need to be able to tell from within a VB.NET class (not a user control) whether or not the current request is a PostBack and/or CallBack (AJAX). In the past I've been able to get information about the request, response, session, etc through HttpContext.Current but I haven't been able to find the Page object in HttpContext.Current. Is...
Hi, I have a dll which accepts a struct that contains a pointer to a function to do a callback. How can I get an IntPtr to a function of my application to build the struct? [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)] public class OPERATION { public uint OperationID; public IntPtr Context; ...
Rather than sending an actual pointer to a value, the value is cast to a pointer. I found these examples in the GUI interface code of a GTK program. g_signal_connect (pastebutton[pane], "clicked", G_CALLBACK(on_paste_button_pressed), (void*)((long)pane<<4)); In the above example, I...
I'm having an issue with a misbehaving behavior. The short of it is that I am hooking into the beforeSave and afterSave callbacks using a behavior, but this has unintended consequences for my situation. Is it possible to replicate this? $this->Model->bsCallback(); if ($this->Model->saveAll($this->data)) { // Model might have other rel...
Is it a function? Is it a function being called from the source? Or, is it a function being returned from the destination? Or, is it just executing a function at the destination? Or, is it a value returned from a function passed to the destination? ...

Hi Experts, I want to something similar to this. function AjaxService() { this.Remove = function (id, call_back) { myWebService.Remove(id, CallBack) } function CallBack(res) { call_back(res); } } so my calling program will be like this var xx = new AjaxService(); xx.Remove(1,success); function success(res)...
I have been using Anthem.NET in ASP.NET 2.0 projects for a few side projects and have a question regarding a slick piece of functionality that appears unique to this framework. I have worked with Telerik and Microsoft ASP.NET AJAX Frameworks and the ability to execute a JavaScript function from within an "ajaxified" control in a code be...
The Python standard library defines an any() function that Return True if any element of the iterable is true. If the iterable is empty, return False. It checks only if the elements evaluate to True. What I want it to be able so specify a callback to tell if an element fits the bill like: any([1, 2, 'joe'], lambda e: isinstance(e,...

In Snow Leopard, I want to trigger a script/code whenever a user duplicates a directory in Finder. How can I do that? I've been hunting around the docs, but I'm a little too new this type of work to recognize the right approach. Motivation: If a directory is under version control, say with git or hg or svn, and the user duplicates tha...
