• Reiterate over a jQuery plugin's this.each()

  - by eth0

  Hi, I'm making a plugin and one of the options is a standard callback. I want the user to be able to re-run the jQuery plugin's this.each() which basically re-runs the plugin, for example; callback: function(){ // some code to rerun the plugin here after 10 seconds } I know I can do this like so: $(this).plugin_name(); but it won't contain any of the options I've specified. Any help would be appreciated.

• Hibernate reverse engineering

  - by EugeneP

  I have a structure where the main table is USER, other tables include CATEGORY (contains user_id). What I got after the standard reverse engineering procedure was: the class User contained a collection of categories, the class Category didn't contain the foreign key (user_id) but it did contain the User object. Why did it not contain the foreign key as a class property? And how do I join these two tables in HQL without that glue? HQL - please explain this part.

• Should Javascript's "for in" construct iterate the length property?

  - by Eric

  I'm making a bookmarklet, but I've encountered some wierd behaviour in IE8. The code causing the problem is this: var els = document.getElementById("my_id").getElementsByTagName("*"); for(var i in els) { alert(i+","+els[i]) } The first thing that is alerted is "length, n". This isn't the case in chrome: just in IE8. Interestingly, it seems to behave differently depending on whether the code goes in the console/address bar or the page itself. Is this standard behaviour?

• do you call them functions, procedures or methods?

  - by lowlyintern

  consider a standard c# 'function' public void foo() { //some code } In c or c++ this is called a 'function' - even if taking no parameters and returning no value. In another language maybe it would be a 'procedure'. In object orientation speak it would be called a 'method' if a class member. What would be the correct term to use in c#?

• C++ Libraries similar to C#?

  - by cam

  I'm coming to C++ from a .Net background. Knowing how to use the Standard C++ Libraries, and all the syntax, I've never ventured further. Now I'm looking learning a bit more, such as what libraries are commonly used? I want to start getting into Threading but have no idea to start. Is there a library (similar to how .net has System.Threading) out there that will make it a bit easier? I'm specifically looking to do Linux based network programming.

• How to remove compiler flag when building Boost

  - by mlo

  I need to build Boost with a non-standard set of flags (due to a conflict between Boost threading and C++/CLI). I'm adding the required flag (/clr) using CXXFLAGS, but this flag conflicts with the Boost default /EHs flag (/clr implies /EHa which is incompatible with /EHs), so that needs to be suppressed. Is there a mechanism like CXXFLAGS to suppress a default Boost flag or must I edit all of the compiler specification files by hand?

• strict string to int[long]

  - by baskin

  Do we have a standard way of converting a char* to int (or long) in a strict way, i.e. we should get proper result only if all characters are digits and can fit in an int (or long) -- some way by using strtol etc.. ? Thus "sbc45", "4590k", " 56", "56 ", should be all invalid using that function.

• How do I clone an OpenLDAP database

  - by elzapp

  I know this is more like a serverfault question than a stackoverflow question, but since serverfault isn't up yet, here I go: I'm supposed to move an application from one redhat server to another, and without very good knowledge of the internal workings of the application, how would I move the OpenLDAP database from the one machine to the other, with schemas and all. What files would I need to copy over? I believe the setup is pretty standard.

  I'm trying svn add *.py --force As the documentation suggests, but I know for a fact it's missing files nested in deeper folders. Why?

• SSIS with different table structures

  - by Grace

  I have a flat file source from Excel that has a structure like this: **People** Day1 Day2 Day3 Day4 Person1 someValue ... Person2 Person3 And i would like the package to put this information in a database with standard columns 'Person', 'Day', 'Value'.

• Does (size_t)((char *)0) ever not evaluate to 0?

  - by Bruce Christensen

  According to the responses in "Why subtract null pointer in offsetof()?" (and my reading of K&R), the C standard doesn't require that (size_t)((char *)0) == 0. Still, I've never seen a situation where casting a null pointer to an integer type evaluates to anything else. If there is a compiler or scenario where (size_t)((char *)0) != 0, what is it?

• Which browsers support html5 offline storage?

  - by Marcin

  Essentially, I wanted to run a piece of demo code from W3c Offline Webapps page. It looks like that: var db = window.openDatabase("notes", "", "The Example Notes App!", 1048576); Firefox 3.5, IE8 and Chrome do not seem to get it. Is there anybody out there that actually wrote support for that? Or is this wishful thinking about 'the standard of the future'?

• Accessing weakly typed facebook sdk result object properties in .NET 3.5 using the API?

  - by John K

  Consider the following in .NET 3.5 (using the Bin\Net35\Facebook*.dll assemblies): var app = new FacebookApp(); var result = app.Get("me"); // want to access result properties with no dynamic ... in the absence of the C# 4.0 dynamic keyword this provides only a generic object. How best should I access the properties of this result value? Are there helper or utility methods or stronger types in the facebook C# sdk, or should I use standard .NET reflection techniques?

  - by TheLearner

  I cannot understand why my MKMapView does not want to change to satellite view. This method is called and case 1 is called I have stepped over it but it simply does not change to satellite type it always changes to standard. It only works when it goes back to Map type. Anyone have any ideas? - (IBAction)mapSatelliteSegmentControlTapped:(UISegmentedControl *)sender { switch (sender.selectedSegmentIndex) { case 1: //Satellite self.mapView.mapType = MKMapTypeSatellite; default: //Map self.mapView.mapType = MKMapTypeStandard; } }

• Why is T() = T() allowed in C++?

  - by Rimo

  I believe the expression T() creates an rvalue (by the Standard) However the following code compiles (at least on gcc4.0) class T {... }; int main() { T() = T(); } I know technically this is possible because member functions can be invoked on temporaries and the above is just invoking the operator= on the r-value temporary created from T(). But conceptually this is like assigning a new value to an r-value. Is there a good reason why this is allowed?
