• How to customise the TextView inside a Spinner?

  - by Janusz

  I have a Spinner with an ArrayAdapter that feeds Values into it. The Problem is that the text is to long for the view and the result is a very very ugly spinner. As can be seen in the screenshot: I tried to pass the Id of my own TextView into the Adapter but everytime the spinner should be shown I get an Exception that the Id I supplied is not valid: 04-26 17:38:39.695: ERROR/AndroidRuntime(4276): android.content.res.Resources$NotFoundException: Resource ID #0x7f09003a type #0x12 is not valid Where do I have to define the TextView? In a separate xml file? With a surrounding viewgroup? It would help me a lot if I could see an example of the adapter initialization and the textview definition?

  - by user2949827

  I want to wright a login script for my organization, The script needs to discover users by Group id's and then define the map drive they need on their computer. I started writing down the script and it looks like this: ID if [gid=10524657] then mkdir /home/likewise-open/Domain/Username/Desktop/Share sudo mount.cifs //fs01/salesnew /home/likewise-open/Domain/Username/Desktop/share -o user=X else [gid=41654564] (etc....) That is the first time i am writing a script in Ubuntu, Can you tell me what am i doing wrong ? Is it possible for Linux to identify the gid from the ID command ? if not what is the alternative option? Can someone please advise ?

• create_function with default parameter values?

  - by SoLoGHoST

  Ok, I'm looking into using create_function for what I need to do, and I don't see a way to define default parameter values with it. Is this possible? If so, what would be the best approach for inputting the params into the create_function function in php? Perhaps using addslashes? Well, for example, I have a function like so: function testing($param1 = 'blah', $param2 = array()) { if($param1 == 'blah') return $param1 else { $notblah = ''; if (count($param2) >= 1) { foreach($param2 as $param) $notblah .= $param; return $notblah; } else return 'empty'; } } Ok, so how would I use create_function to do the same thing, adding the parameters and their default values? The thing is, the parameters are coming from a TEXT file, as well as the function itself. So, wondering on the best approach for this using create_function and how exactly the string should be parsed. Thanks :)

• Can't inherit from auto_ptr without problems

  - by fret

  What I want to do is this: #include <memory> class autostr : public std::auto_ptr<char> { public: autostr(char *a) : std::auto_ptr<char>(a) {} autostr(autostr &a) : std::auto_ptr<char>(a) {} // define a bunch of string utils here... }; autostr test(char a) { return autostr(new char(a)); } void main(int args, char **arg) { autostr asd = test('b'); return 0; } (I actually have a copy of the auto_ptr class that handles arrays as well, but the same error applies to the stl one) The compile error using GCC 4.3.0 is: main.cpp:152: error: no matching function for call to `autostr::autostr(autostr)' main.cpp:147: note: candidates are: autostr::autostr(autostr&) main.cpp:146: note: autostr::autostr(char*) I don't understand why it's not matching the autostr argument as a valid parameter to autostr(autostr&).

• How to force adodb php library to use lowercase field names

  - by spam

  I'm trying to use adodb for db access in my webapp. However my hosting provider has mysql case sensitive, and I have all my fields in lowercase. But when I call getInsertSQL function, I got them in uppercase. Is there a way to force adodb to use lowercase? I tried with define('ADODB_ASSOC_CASE', 0); $ADODB_ASSOC_CASE = 0; But it seems to be ignored as the constant is suppose to be used only with oracle, MSSQL and other DBMS $conn = &ADONewConnection($this->DbType); $conn = PConnect($dbServer,$dbUser, $dbPassword,$database); $tableName = "sample"; $insertSQL = $conn->GetInsertSQL($tableName,$objDB); And I got the SQL statement with the column names in uppercase.

• How to apply encoding when reading from a serial port

  - by rross

  I'm reading data from a serial port. I read this posting: http://social.msdn.microsoft.com/Forums/en-US/vbgeneral/thread/a709d698-5099-4e37-9e10-f66ff22cdd1e He is writing about many of the issues I have encounter, but in his writing he refers to using: System.Text.Encoding.GetEncoding("Windows-1252"). The problem I'm having is when and how to apply this. There are three potitional spots in my opinion. When the serial port object is define: private SerialPort comport = new SerialPort(); The Event handler: comport.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived); Or when reading the data: string data = comport.ReadExisting(); No matter where I add it. I seem to get errors. How would one use Encoding?

• Indexes and multi column primary keys

  - by David Jenings

  Went searching and didn't find the answer to this specific noob question. My apologies if I missed it. In a MySQL database I have a table with the following primary key PRIMARY KEY id (invoice, item) In my application I will also frequently be selecting on "item" by itself and less frequently on only "invoice". I'm assuming I would benefit from indexes on these columns. MySQL does not complain when I define the following: INDEX (invoice), INDEX (item), PRIMARY KEY id (invoice, item) But I don't see any evidence (using DESCRIBE -- the only way I know how to look) that separate indexes have been established for these two columns. So the question is, are the columns that make up a primary key automatically indexed individually? Also, is there a better way than DESCRIBE to explore the structure of my table?

• Best way to order menu items injected by an IoC/plugin Framework

  - by Daver

  One of the common things I've seen done in applications built on IoC/plugin frameworks is to add commands to menus or toolbars from the dynamically loaded plugins. For example, the application's default plugins supply actions like "New, Open, Save" that show up in the context menu for a certain item in the workspace. A new plugin may add "Mail, Post, Encrypt" commands, but where do those commands show up in relation to "New, Open, Save"? How can the application that is loading components through IoC impose order on the items that get injected? Does it require metadata from the plugins that give a hint on how to group or order the items? Does it use a config file of previously known menu names (or ids) to define the order (seems a little weak to me)? Or are "unknown" plugins treated as second class citizens and always get dumped into sub menus? Something I've never even imagined (which I'm hoping to see in the answers)

• Database design: How should I add an information which can apply to several tables

  - by Stefan

  I am constructing a database System using Mysql, this will be an application of about 20 tables. The system contains information on farmers, we work with organic certification and need to record a lot of info for that. In my system, there are related parent-child tables for farmers, producing years and fields/areas - it's a simple representation of the real world in which farmers farm crops on their fields. I now need to add several status flags for each one of these levels: a farmer can be certified, or his field can be, or the specific year can be; each of these flags has several states and can occur a number of times. The obvious solution to this would be to add a child table to every one of these tables, and define the states there. What I wonder if there is an easier way to do this to avoid getting to many tables? Where/how would be best practise to keep that data?

• Real world examples of Ecmascript functions returning a Reference?

  - by Bergi

  Read the EcmaScript specification, section 8.7 The Reference Specification Type: The Reference type is used to explain the behaviour of such operators as delete, typeof, and the assignment operators. […] A Reference is a resolved name binding. Function calls are permitted to return references. This possibility is admitted purely for the sake of host objects. No built-in ECMAScript function defined by this specification returns a reference and there is no provision for a user-defined function to return a reference. Those last two sentences impressed me. With this, you could do things like coolHostFn() = value (valid syntax, btw). So my question is: Are there any EcmaScript implementations that define host function objects which result in Reference values?

• Always require a plugin to be loaded

  - by axon

  I am writing an application with RequireJS and Knockout JS. The application includes an extension to knockout that adds ko.protectedObservable to the main knockout object. I would like this to always be available on the require'd knockout object, and not only when I specify it in the dependencies. I could concat the files together, but that seems that it should be unnecessary. Additionally, I can put knockout-protectedObservable as a dependency for knockout in the requirejs shim configuration, but that just leads to a circular dependency and it all fails to load. Edit: I've solved me issue, but seems hacky, is there a better way? -- Main.html <script type="text/javascript" src="require.js"></script> <script type="text/javascript"> require(['knockout'], function(ko) { require(['knockout-protectedObservable']); }); </script> -- knockout-protectedObservable.js define(['knockout'], function(ko) { ko.protectedObservable = { ... }; });

• Finding cities close to one another using longitude and latitude

  - by Jamie

  Each user in my db is associated to a city (with it's longitude and latitude) How would I go about finding out which cities are close to one another? i.e. in England, Cambridge is fairly close to London. So If I have a user who lives in Cambridge. Users close to them would be users living in close surrounding cities, such as London, Hertford etc. Any ideas how I could go about this? And also, how would I define what is close? i.e. in the UK close would be much closer than if it were in the US as the US is far more spread out. Ideas and suggestions. Also, do you know any services that provide this sort of functionality? Thanks

• Any reccomendations for implementing a user-defined workflow in Ruby?

  - by midas06

  I'm interested in creating a system where the user can define the steps in a workflow. Is there a gem that already handles this? I thought about one of the state machine gems, but they all seem to be for pre-defined states. I've been thinking maybe i can use state machine for the individual step types... An email step could have a few states [New, Assigned, Done], and the workflow could just be lists of these stateful steps. Are there other solutions out there?

• defining information out of class

  - by calccrypto

  is there a way to define a value within a class in the __init__ part, send it to some variable outside of the class without calling another function within the class? like class c: def __init__(self, a): self.a = a b = 4 # do something like this so that outside of class c, # b is set to 4 automatically when i use class c def function(self): ... # whatever. this doesnt matter i have multiple classes that have different values for b. i could just make a list that tells the computer to change b, but i would rather set b within each class

• why isn't my id showing up in django admin list?

  - by FurtiveFelon

  Hi all, I have a class Task(models.Model), and i didn't define id field explicitly (since it defines automatically for you). I checked in the database, it exists for the Task. Now i would like to display it in the list via list_display property in admin.ModelAdmin. I have a bunch of things in there, only id is not showing up for any of the rows i have. Everything else works fine. Anyone know anything special i have to do to get id to display? Thanks a lot! Jason

• XML Schema Header & Namespace Config

  - by zharvey

  Migrating from DTD to XSD and for some reason the transition is a bumpy one. I understand how to define the schema once I'm inside the <xs:schema> root tag, but getting past the header & namespace declaration stuff is proving to be especially confusing for me. I have been trying to follow the well-laid out tutorial on W3S but even that tutorial seems to assume a lot of knowledge up front. I guess what I'm looking for is a King's English explanation of which attributes do what, where they go, and why: xmlns xmlns:xs xmlns:xsi targetNamespace xsi:schemaLocation And in some cases I see different variations of these elements/attributes, such as xsi which seems to have two different notations like xsi:schemaLocation="..." and xs:import schemaLocation="...". I guess between all these slight variations I can't seem to make heads or tails of what each of these does. Thanks in advance for bringing any clarity to this confusion!

• How to create a new IDA project based on an existing one with different offsets?

  - by tbergelt

  I have an existing IDA Pro project for a C166 processor embedded application. This project already has many functions, variables, etc defined. There are different versions of the embedded application I am looking at. The different versions of the application are 99% the same, but with slight variations in code and data that cause functions and variables to be at different memory offsets. I want to create a new IDA project for a different version of the application. I would like to somehow import all of my function and variable definitions from my existing IDA project. I would like IDA to recognize the signatures of the existing function definitions and define them at there new location in the new project. How can I do this? Are there certain plugins for IDA I can chain together?

• How to get Doxygen to recognize custom latex command

  Is there a way to use extra latex packages and/or extra latex commands with Doxygen code documentation system. For example I define the shortcut in a custom sty file. \newcommand{\tf}{\Theta_f} Then I use it about 300 time in the code, which is across about a dozen files. /*! Stochastic approximation of the latent response*/ void dual_bc_genw( //... double const * const psi, ///< \f$ \psi = B\tf \f$ //... ){/* lots of brilliant code */} But how do I get the system to recognize the extra package.

• How do I find the screen size in a fragment class

  - by thomas.cloud

  I was looking at this posting: Android: How to get screen dimensions when I was trying to determine the size of the device's screen while in a fragment class. One answer was close to what I needed but the only code that ended up working for me was: WindowManager wm = (WindowManager) getView().getContext().getSystemService(Context.WINDOW_SERVICE); Display screen = wm.getDefaultDisplay(); whereupon I could then use getHeight(); or another non-deprecated term. I realize this is exactly the same as the other site except this way you don't have define your context on a separate line.

• How do I dynamically update an instance array to hold a list of dynamic methods on instantiation?

  - by Will

  I am trying to dynamically define methods based on xml mappings. This works really well. However I want to create an instance variable that is a array of the dynamically defined methods. My code looks something like this def xml_attr_reader(*args) xml_list = "" args.each do |arg| string_val = "def #{arg}; " + " xml_mapping.#{arg}; " + "end; " self.class_eval string_val xml_hash = xml_list + "'#{arg}'," end self.class_eval "@xml_attributes = [] if @xml_attributes.nil?;" + "@xml_attributes = @xml_attributes + [#{xml_list}];" + "puts 'xml_attrs = ' + @xml_attributes.to_s;" + "def xml_attributes;" + " puts 'xml_attrs = ' + @xml_attributes.to_s;" + " @xml_attributes;" + "end" end So everything works except when I call xml_attributes on an instance it return null (and prints out 'xml_attrs = '). While the puts before the definition actually prints out the correct array. (when I instantiate the instance)

• C++ inheritance and member function pointers

  - by smh

  In C++, can member function pointers be used to point to derived (or even base) class members? EDIT: Perhaps an example will help. Suppose we have a hierarchy of three classes X, Y, Z in order of inheritance. Y therefore has a base class X and a derived class Z. Now we can define a member function pointer p for class Y. This is written as: void (Y::*p)(); (For simplicity, I'll assume we're only interested in functions with the signature void f() ) This pointer p can now be used to point to member functions of class Y. This question (two questions, really) is then: Can p be used to point to a function in the derived class Z? Can p be used to point to a function in the base class X?

• prevent using functions before initialization, constructors-like in C

  - by Hernán Eche

  This is the way I get to prevent funA,funB,funC, etc.. for being used before init #define INIT_KEY 0xC0DE //any number except 0, is ok static int initialized=0; int Init() { //many init task initialized=INIT_KEY; } int funA() { if (initialized!=INIT_KEY) return 1 //.. } int funB() { if (initialized!=INIT_KEY) return 1 //.. } int funC() { if (initialized!=INIT_KEY) return 1 //.. } The problem with this approach is that if some of those function is called within a loop so "if (initialized!=INIT_KEY)" is called again, and again, although it's not necessary. It's a good example of why constructors are useful haha, If it were an object I would be sure that when was created initialization was called, but in C, I don't know how to do it. Any other ideas are welcome!
