• Should a g_object_new have a matching g_object_unref?

  - by legends2k

  I'm using libnotify to show desktop notifications in my application; notify_notification_new() returns a NotifyNotification*, which should be passed as the first param to further function calls of the notification library. There is no notify_notification_free() which frees the pointer it returns. I looked up the source of notify_notification_new() and internally it does a g_object_new(), gets a GObject* and returns it as a NotfiyNotification*, so when my application does the clean up, should I call a g_object_unref() on the pointer returned by notify_notification_new()?

• activemodel for rails < 3

  - by brad

  Does anyone know if activemodel works with 2.3.5? I'm looking for this exact functionality (namely, validations for non-AR objects) and I'm trying to find a clean solution for a Rails 2.3.5 app. Or if anyone knows of a good gem/plugin to use that can mimic activerecord like validations for non AR objects, I'm all ears

• datagridview rowsremoved event gets called every time data loads

  - by Nilotpal Das

  The datagridview rowsremoved event gets called every time the data gets loaded. It also makes sense to a certain extent that every time the data loads, the existing rows are removed. so technically the event should get called. But how do i differenciate that from the actual delete button getting pressed. I don't think the key events should be used, that wouldn't be a clean approach. Any help will be most appreciated.

• jQuery Templates vs Partial Views in ASP.NET MVC

  - by Jaco Pretorius

  I'm taking a look at jQuery templates. It looks really interesting - easy syntax, easy to use, very clean. However, I can't really see why it's better to use jQuery templates instead of simply fetching partial views via AJAX. It simply seems like the partial views would be much easier to maintain and helps to avoid duplication of code. I want to use jQuery templates. But when would it be better than partial views?

• Cleansing string / input in Coldfusion 9

  - by Jakub

  I have been working with Coldfusion 9 lately (background in PHP primarily) and I am scratching my head trying to figure out how to 'clean/sanitize' input / string that is user submitted. I want to make it HTMLSAFE, eliminate any javascript, or SQL query injection, the usual. I am hoping I've overlooked some kind of function that already comes with CF9. Can someone point me in the proper direction?

• Where to wire up events?

  - by Jeffrey Cameron

  I'm using Ninject (1.5 ... soon to be 2) and I'm curious how other people use Ninject or other IoC containers to help wire up events to objects? It seems to me in my code that I'm doing it herky-jerky all over the place and would love some advice on how to clean it up a bit.

• Find and replace table/field names in Access?

  - by richardtallent

  I've been handed a rather large, old, and crusty Access 2000/2003 database to clean up. I'll need to rename a number of tables and fields, but need to do so in a way that doesn't break existing queries. (Fortunately, there are no macros, forms, or reports to worry about.) I've heard there are some commercial tools to make this job easier, but only found one (http://www.rickworld.com/products.html). Can anyone recommend this software, or any alternatives?

• SWT: cleaning up before application exit

  - by Alexey Romanov

  What is the best way for an SWT application to clean up resources before application exit? I see two options: 1) Add a DisposeListener to main window (or better, to the Display). Will it get run if an uncaught exception happens? 2) Use a shutdown hook. Any problems to be aware of there which aren't mentioned in Design of the Shutdown Hooks API?

• Is it reasonable to use OpenGL for desktop applications?

  - by JamesK89

  I've been writing a small desktop gadget-type application that displays scrolling text along the bottom of the screen (Similar to the old CNN news ticker), however the performance of GDI is just unsatisfactory (As high as 8-12% on a quad core and 20% on a single core) even after I've attempted to clean out bottlenecks. I was considering using OpenGL instead to render everything, but I don't know if that is a reasonable option to require users to have hardware acceleration for a tiny app like this. Does anybody have any input on this?

• how to separate debug and release mode code

  - by john

  during debug mode or while i am doing testing, i need to print lost of various information, so i use this method ifdef TESTING // code with lots of debugging info else // clean code only endif // TESTING` Is this the good method, or is there any other simple and elegant method. But this way, I am repating the same code in two places and if anything is to be changed later on in the code, I have to do it in both places, which is time consuming and error prone. Thanks. I am using MS Visual Studio.

• Java method get the inheriting type

  - by DrDro

  I have several classes that extend C and I would need a method that accepts any argument of type C. But in this method I would like to know if I'm dealing with A or B. * public A extends C public B extends C public void goForIt(C c)() If I cast how can I retrieve the type in a clean way (I just read using getClass or instanceof is often not the best way). PS: Fell free to edit an explicit title. *Sorry but I can't type closing braces

  I've got two Urls. A server and a relative url that I would like to combine. The problem is that part of the url's may well overlap.

• how to deal with political differences that lead to dysfunctional development environment

  - by Pierreten

  We have a few liberal programmers on our team who don't use source control, don't manage time effectively and always want to use our budget on useless tools/components that are expensive and things we can build ourselves. They are also loud and disrespectful. Our group of conservatives always have to clean up after them and show them the correct way of doing things. How do we address this discrepancy? Please advise.

• VB.NET: question about "using" block

  - by Craig Johnston

  Consider the code: On Error Goto ErrorHandler Using sr As StreamReader = New StreamReader(OpenFile) str = sr.ReadToEnd sr.Close() End Using Exit Sub ErrorHandler: If there is an error inside the Using block how do you clean up the sr object? The sr object is not in scope in ErrHandler so sr.Close() cannot be called. Does the Using block cleanup any resources automatically even if there is an error?

• C++ DLL Export: Decorated/Mangled names

  - by Bob

  Created basic C++ DLL and exported names using Module Definition file (MyDLL.def). After compilation I check the exported function names using dumpbin.exe I expect to see: SomeFunction but I see this instead: SomeFunction = SomeFunction@@@23mangledstuff#@@@@ Why? The exported function appears undecorated (especially compared to not using the Module Def file), but what's up with the other stuff? If I use dumpbin.exe against a DLL from any commercial application, you get the clean: SomeFunction and nothing else......
