• Clickable TextView in Android

  - by Cris

  i'm building an Android App that has many many TextView that i want to be clickable. I've tried to assign to the single TextView the properties android:clickable="true" and android:onClick="clickHandler" and when the app fires the clickHandler(View v) i correctly get, through the v.getId(), the clicked item. What i don't like is to define, for every TextView, the properties android:clickable and android:onClick ... is there something that i can do by code to say: "all the textviews are clickable and click is handled in 'clickHandler' ?" Thanks and greetings c

• How can you tell if an activities state is stored?

  - by Joren

  I have an activity which pulls some JSON from my server, and then uses it to draw a list. That list launches further activities. My problem is that I can't figure out a way to tell if the activity is still alive when you go back to it, so I end up re-querying my JSON from the server and redrawing the list every time the user goes back to the activity. How can I tell if my activity is still alive so I can skip the redraw?

• How can I schedule a Task to execute at a specific time using celery?

  - by Hank Gay

  I've looked into PeriodicTask, but the examples only cover making it recur. I'm looking for something more like cron's ability to say "execute this task every Monday at 1 a.m."

• Crystal reports CSV incorrect generation

  - by yauhen

  When setting ExportFormatType.CharacterSeparatedValues crystal report generates every row of data prefixed with column names (Report Headers). Why it does this? How it could be fixed? Usually it is preferred to have single header. For excel export type - generated report looks ok (only single header for all rows). I am using crystal reports 11.5.3700.0. Visual studio 2008, .net 3.5 sp1

• Supporting multiple instances of a plugin DLL with global data

  - by Bruno De Fraine

  Context: I converted a legacy standalone engine into a plugin component for a composition tool. Technically, this means that I compiled the engine code base to a C DLL which I invoke from a .NET wrapper using P/Invoke; the wrapper implements an interface defined by the composition tool. This works quite well, but now I receive the request to load multiple instances of the engine, for different projects. Since the engine keeps the project data in a set of global variables, and since the DLL with the engine code base is loaded only once, loading multiple projects means that the project data is overwritten. I can see a number of solutions, but they all have some disadvantages: You can create multiple DLLs with the same code, which are seen as different DLLs by Windows, so their code is not shared. Probably this already works if you have multiple copies of the engine DLL with different names. However, the engine is invoked from the wrapper using DllImport attributes and I think the name of the engine DLL needs to be known when compiling the wrapper. Obviously, if I have to compile different versions of the wrapper for each project, this is quite cumbersome. The engine could run as a separate process. This means that the wrapper would launch a separate process for the engine when it loads a project, and it would use some form of IPC to communicate with this process. While this is a relatively clean solution, it requires some effort to get working, I don't now which IPC technology would be best to set-up this kind of construction. There may also be a significant overhead of the communication: the engine needs to frequently exchange arrays of floating-point numbers. The engine could be adapted to support multiple projects. This means that the global variables should be put into a project structure, and every reference to the globals should be converted to a corresponding reference that is relative to a particular project. There are about 20-30 global variables, but as you can imagine, these global variables are referenced from all over the code base, so this conversion would need to be done in some automatic manner. A related problem is that you should be able to reference the "current" project structure in all places, but passing this along as an extra argument in each and every function signature is also cumbersome. Does there exist a technique (in C) to consider the current call stack and find the nearest enclosing instance of a relevant data value there? Can the stackoverflow community give some advice on these (or other) solutions?

• Can an attribute's target be derived from an instance of the attribute?

  - by Hounshell

  Example: [AttributeUsage(AttributeTargets.Class)] public class MyAttribute : Attribute { public MyAttribute() { Console.WriteLine("I was defined on the {0} class", ????); } } [MyAttribute] public class MyClass { } Can I fill in the "????" to answer this question? Do I have to iterate over every type in the list of known assemblies to do it? Or is there a shorter way?

• Handling apostrophes, php and pgsql

  - by running4surival

  For my forms, I'm using pg_escape_string on every field before I insert them into the database. So I get something like firstname='O''reilly'. But when I try to print that out, I get O''reily, 2 apostrophes. Shouldn't it only 1 apostrophe, O'reilly? This isnt a debugging problem, im just wondering if you have firstname='O''reilly', how do you print that so it is just O'reilly instead of O''reilly?

• How to connect to a secure FtP from my website/web application?

  - by msandbot

  Hi, I'm working on making a website/web application that displays images every 5 or so minutes, kinda like a webcam. The images are uploaded to an SFTP server. How can I access those from the web? Does anyone have any recommendations for what to use as well? Right now I'm looking at PHP but have checked out javascript and ruby as well. Only the application needs to ssh to a predetermined place, not the users.

• TeamCity build number independent artifacts

  - by Stanislav Shevchenko

  Hello, My TeamCity's nightly build produces more than 130Mb java doc as Build Configuration artifact. I have to share these artifact for other teams(developers), but javadoc every time has another one URL(I know that it's possible to get it like .lastFinished), and get's new place on Build Machine. Is it possible on each build replace old artifact with new one because I don't need need previous versions? And have independent from build version URL for accessing.

• What is the best way to open a URL and get up to X bytes in Python?

  - by Stavros Korokithakis

  I want to have a robot fetch a URL every hour, but if the site's operator is malicious he could have his server send me a 1 GB file. Is there a good way to limit downloading to, say, 100 KB and stop after that limit? I can imagine writing my own connection handler from scratch, but I'd like to use urllib2 if at all possible, just specifying the limit somehow. Thanks!

• Memory release from local variable in javascript

  - by Bob

  Quick question. I have a js function which gets called on the page every few seconds. It's an ajax update thing. Being a function, I declare local variables. I don't want to use closures or global variables for various reasons. I'd never considered this, but do I need to release/clear the variables at the end of the function to release memory or will js do this for me automatically ? Thanks

• What is a 'better' approach to query/save from server: DTO or Wcf Data Services?

  - by bonefisher

  From my perspective, the Data Services and their query approach is useful when querying simple object graphs from your server-side domain model. But when you want to query complex dependencies I couldn't create anything good out of it. The classic DTO approach is fine-grained and can handle everything, but the downside is that you have to create Dto classes for every type of server-request which is time consuming and you have to synchronize the Dto type with your domain entity/business logic.

• Can you make an incrementing compiler constant?

  - by Keith Nicholas

  While sounding nonsensical..... I want a Contant where every time you use it it will increment by 1 int x; int y; x = INCREMENTING_CONSTNAT; y = INCREMENTING_CONSTNAT; where x == 1; and y == 2 Note I don't want y = INCREMENTING_CONSTNAT+1 type solutions. Basically I want to use it as a compile time unique ID ( generally it wouldn't be used in code like the example but inside another macro)

• How exactly does a python (django) request happen? does it have to reparse all the codebase?

  - by Blankman

  With a scripting language like python (or php), things are not compiled down to bytecode like in .net or java. So does this mean that on every request, it has to go through the entire application and parse/compile it? Or at least all the code required for the given call stack?
