  • Cutting down repeating code in c# Class

    - by Tom Gullen
    This is a wrapper for an API I'm working on, am I doing it sort of right? I'm not particularly fond of all the repeating code in the constructor, if someone can show me if I can reduce that it would be very helpful! public class WebWizForumVersion { // Properties of returned data public string Software { get; private set; } public string Version { get; private set; } public string APIVersion { get; private set; } public string Copyright { get; private set; } public string BoardName { get; private set; } public string URL { get; private set; } public string Email { get; private set; } public string Database { get; private set; } public string InstallationID { get; private set; } public bool NewsPad { get; private set; } public string NewsPadURL { get; private set; } public WebWizForumVersion(XmlReader Data) { try { Data.ReadToFollowing("Software"); this.Software = Data.ReadElementContentAsString(); Data.ReadToFollowing("Version"); this.Version = Data.ReadElementContentAsString(); Data.ReadToFollowing("ApiVersion"); this.APIVersion = Data.ReadElementContentAsString(); Data.ReadToFollowing("Copyright"); this.Copyright = Data.ReadElementContentAsString(); Data.ReadToFollowing("BoardName"); this.BoardName = Data.ReadElementContentAsString(); Data.ReadToFollowing("URL"); this.URL = Data.ReadElementContentAsString(); Data.ReadToFollowing("Email"); this.Email = Data.ReadElementContentAsString(); Data.ReadToFollowing("Database"); this.Database = Data.ReadElementContentAsString(); Data.ReadToFollowing("InstallID"); this.InstallationID = Data.ReadElementContentAsString(); Data.ReadToFollowing("NewsPad"); this.NewsPad = bool.Parse(Data.ReadElementContentAsString()); Data.ReadToFollowing("NewsPadURL"); this.NewsPadURL = Data.ReadElementContentAsString(); } catch (Exception e) { } } }

  • Core Data: Detecting the type and casting it

    - by Tim Sullivan
    I have set up a Core Data model that includes an entity, Item with a 1-M relationship with the abstract entity Place, so that an item has many places. There are several entities with the parent set to Place. I want to set up several UI elements depending on the descendent place types. I have a loop that looks something like this: for (Place *place in item.places) { } ... but I'm not sure how to detect what type the place is, and how to cast it to the proper type so that I can access its properties. Thanks for any help!

  • How can a property resolve its own name and type with reflection?

    - by Tim Santeford
    Is there a way for a property to access its own name and type at runtime using reflection? I want to access this info without hard coding the name or index of the property in the class. Simple Example Code: Private ReadOnly Property MyProperyName() As String Get Console.WriteLine((Get Current Property Info).Type.ToString) Console.WriteLine((Get Current Property Info).Name) Return "" End Get End Property Expected output: System.String MyPropertyName

  • Java Compare Addresses

    - by Tom
    Hi, Does anyone know a library to compare addresses in Java ? Something that would give equality on addresses, written in different ways. For example, it should recognize that "22 Acacia Avenue" and "22 acacia av." is the same address. Of course, this can escalate a lot, that's why i'm asking. Thanks in advance.

  • Eclipse Type Hierarchy Question

    - by Tom Tresansky
    In Eclipse, the Java Method Override Indicator is the little upwards arrow next to a method in the Type Hierarchy view. A solid arrow means a method overrides an existing method lower in the hierarchy. What does the hollow arrow mean? Do annotations effect either arrow?

  • How to get the parameter names of an object's constructors (reflection)?

    - by Tom
    Say I somehow got an object reference from an other class: Object myObj = anObject; Now I can get the class of this object: Class objClass = myObj.getClass(); Now, I can get all constructors of this class: Constructor[] constructors = objClass.getConstructors(); Now, I can loop every constructor: if (constructors.length > 0) { for (int i = 0; i < constructors.length; i++) { System.out.println(constructors[i]); } } This is already giving me a good summary of the constructor, for example a constructor public Test(String paramName) is shown as public Test(java.lang.String) Instead of giving me the class type however, I want to get the name of the parameter.. in this case "paramName". How would I do that? I tried the following without success: if (constructors.length > 0) { for (int iCon = 0; iCon < constructors.length; iCon++) { Class[] params = constructors[iCon].getParameterTypes(); if (params.length > 0) { for (int iPar = 0; iPar < params.length; iPar++) { Field fields[] = params[iPar].getDeclaredFields(); for (int iFields = 0; iFields < fields.length; iFields++) { String fieldName = fields[i].getName(); System.out.println(fieldName); } } } } } Unfortunately, this is not giving me the expected result. Could anyone tell me how I should do this or what I am doing wrong? Thanks!

  • Android - Opening phone deletes app state

    - by Tom G
    Hey everyone, I'm writing an android application that maintains a lot of "state" data...some of it I can save in the form of onSaveInstanceState but some of it is just to complex to save in memory. My problem is that sliding the phone open destroys/recreates the app, and I lose all my application state in the process. The same thing happens with the "back" button, but I overloaded that function on my way. Is there any way to overload the phone opening to prevent it from happening? Thanks in advance.

  • Is PKCS#1 V2.0 implemented for Java?

    - by Tom Brito
    I need encrypt data using exactly the PKCS#1 V2.0 encryption method (defined in item 7.2.1 of the PKCS#1V2 specification). Is it already implemented for Java? I'm thinking in something like just pass a parameter to javax.crypto.Cipher specifying "PKCS#1V2", I wonder if there is something like this?

  • Euler rotation of direction vector

    - by Tom Savage
    I have defined an object in 3D space with position, rotation and scale values (all defined as 3D vectors). It also has upwards and forwards direction vectors. When I rotate the object, I need these direction vectors to rotate with it. Assuming my up vector is (0, 1, 0) and my forwards vector is (0, 0, 1) at zero rotation, how might I achieve this?

  • C# How to output to GUI when data is coming via an interface via MarshalByRefObject?

  • Returning a lua table on SWIG call

    - by Tom J Nowell
    I have a class with a methodcalled GetEnemiesLua. I have bound this class to lua using SWIG, and I can call this method using my lua code. I am trying to get the method to return a lua table of objects. Here is my current code: void CSpringGame::GetEnemiesLua(){ std::vector<springai::Unit*> enemies = callback->GetEnemyUnits(); if( enemies.empty()){ lua_pushnil(ai->L); return; } else{ lua_newtable(ai->L); int top = lua_gettop(ai->L); int index = 1; for (std::vector<springai::Unit*>::iterator it = enemies.begin(); it != enemies.end(); ++it) { //key lua_pushinteger(ai->L,index);//lua_pushstring(L, key); //value CSpringUnit* unit = new CSpringUnit(callback,*it,this); ai->PushIUnit(unit); lua_settable(ai->L, -3); ++index; } ::lua_pushvalue(ai->L,-1); } } PushIUnit is as follows: void CTestAI::PushIUnit(IUnit* unit){ SWIG_NewPointerObj(L,unit,SWIGTYPE_p_IUnit,1); } To test this I have the following code: t = game:GetEnemiesLua() if t == nil then game:SendToConsole("t is nil! ") end The result is always 't is nil', despite this being incorrect. I have put breakpoints in the code and it is indeed going over the loop, rather than doing lua_pushnil. So how do I make my method return a table when called via lua?

  • Facebook API - Detect if session is active OR NOT active

    - by Tom Doe
    I'm sure I'm simply overlooking something in the Facebook API docs. Basically, after I've loaded the FB Graph, I need to know if the session is active... I cannot simply assume they're logged out and simply re-render if they're logged in once the 'auth.statusChange' event is triggered. I need to know right off the bat. Below is the code that I've used. Most importantly the FB.getLoginStatus/getAuthResponse/getAccessToken don't work like I'd expect; essentially where it indicates, when invoked, whether they're logged in or out. (function(d) { // Create fb-root var fb_root = document.createElement('div'); fb_root.id = "fb-root"; document.getElementsByTagName('body')[0].appendChild( fb_root ); // Load FB Async var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0]; if (d.getElementById(id)) {return;} js = d.createElement('script'); js.id = id; js.async = true; js.src = "//connect.facebook.net/en_US/all.js"; ref.parentNode.insertBefore(js, ref); // App config-data var config = { appId : XXXX, cookie: true, status: true, frictionlessRequests: true }; window.fbAsyncInit = function() { // This won't work. // I can't assume they're logged out and rely on this to tell me they're logged in. FB.Event.subscribe('auth.statusChange', function(response) {}); // Init FB.init(config); // These do not inidicate if the user is logged out :( FB.getLoginStatus(function(response) { }); FB.getAuthResponse(function(response) { }); FB.getAccessToken(function(response) { }); }; }(document)); Any help is much appreciated. :)

  • Symfony: Web debug toolbar icons disappeared

    - by Tom
    Hi, Just moved a symfony project from local (win) to server (linux), and the icons in the web debug toolbar have disappeared. Only the image alts remain so I guess it's a path issue with the images. Basically, I see "Time 300ms" instead of "[icon] 300ms" for each of the items. I'm a little worried that some other paths aren't broken as well that are going to be a pain to find. Has anyone had/resolved this issue? Thank you.

  • Database tables with dynamic information

    - by Tim Fennis
    I've googled this and found that it's almost impossible to create a database with dynamic collumns. I'll explain my problem first. I am making a webshop for a customer. It has multiple computer products for sale. CPU's HDD's RAM ect. All these products have different properties, a CPU has an FSB, RAM has a CAS latency. But this is very inconvenient because my orders table needs foreign keys to different tables which is impossible. An other option is to store all the product specific information in a varchar or blob field and let PHP figure it out. The problem with this solution is that the website needs a PC builder. A step-by-step guide to building your PC. So for instance if a customer decides he wants a new "i7 920" or whatever i want to be able to sellect all motherboards for socket 1366, which is impossible because all the data is stored in one field. I know it's possible to select all motherboards form the DB and let PHP figure out which ones are for socket 1366 but i was wondering, is there a better solution?

  • Sharing class member data between sub components

    - by Tim Gradwell
    I have an aggregate 'main' class which contains some data which I wish to share. The main class also has other class members. I want to share the data with these other class members. What is the correct / neatest way to do this? The specific example I have is as follows. The main class is a .net Form. I have some controls (actually controls within controls) on the main form which need access to the shared data. Main Form - DataX - DataY - Control1 -- Subcontrol1 - Control2 -- SubControl2 SubControls 1 and 2 both wish to access DataX and DataY. The trouble is, I feel like better practice (to reduce coupling), would be that either subcontrols should not know about Main Form, or Main Form should not know about subcontrols - probably the former. For subcontrols not to know about Main Form, would probably mean Main Form passing references to both Controls 1 and 2, which in turn would pass the references on to SubControls 1 and 2. Lots of lines of code which just forward the references. If I later added DataZ and DataW, and Controls 3 and 4 and SubControls 3 and 4, I'd have to add lots more reference forwarding code. It seems simpler to me to give SubControls 1 and 2 member references to Main Form. That way, any sub control could just ask for MainForm.DataX or MainForm.DataY and if I ever added new data, I could just access it directly from the sub controls with no hassle. But it still involves setting the 'MainForm' member references every time I add a new Control or Subcontrol. And it gives me a gut feeling of 'wrong'. As you might be able to tell I'm not happy with either of my solutions. Is there a better way? Thanks

  • Could random.randint(1,10) ever return 11?

    - by Tim Pietzcker
    When researching for this question and reading the sourcecode in random.py, I started wondering whether randrange and randint really behave as "advertised". I am very much inclined to believe so, but the way I read it, randrange is essentially implemented as start + int(random.random()*(stop-start)) (assuming integer values for start and stop), so randrange(1, 10) should return a random number between 1 and 9. randint(start, stop) is calling randrange(start, stop+1), thereby returning a number between 1 and 10. My question is now: If random() were ever to return 1.0, then randint(1,10) would return 11, wouldn't it?

  • Taking over someone else's code

    I am taking over someone elses code. What are some good ways to learn what that programmer did as quickly as possible? I have been running it, stepping through it and looking at the callstack. What else can I do? Sorry I forgot to mention, but there is little documentation and I have been trying to fix simple problems. Thanks!

What should I change in my code or web.config to make this webapp load OK also in new 2008 server? Now I receive this error when I access the application: This type is in IMPORTS ( Dll ). Compiler Error Message: BC30002: Type 'Facebook.Entity.User' is not defined.
