  • deleting dynamically allocated object that contains vector in C++ STL

    - by kobac
    I have a class class ChartLine{ protected: vector<Point> line; // points connecting the line CString name; //line name for legend CPen pen; //color, size and style properties of the line }; where Point is a structure struct Point{ CString x; double y; }; In main() I dynamically allocate objects of type ChartLine with new operator. If I use delete afterwards, will default destructor ~ChartLine() properly dealocate (or clear) member ChartLine::line(which is vector btw) or I would have to clear that vector in ~ChartLine() manually? Thanks in advance. Cheers.

  • AS3 Components in Flash Designer

    - by Jack Voight
    In an ActionScript 2 project I can create a new MovieClip, right-click on it on the library and select "Component Definition" to add parameters that can be referenced inside the MovieClip. This parameters can be easily changed in the MovieClips's properties. Now, I'm working on an ActionScript 3 project but haven't been able to figure out a way to obtain the values passed in those parameters. I defined a parameter named "textToDisplay" but when I write the following in the Actions for the first frame I get an error: trace(textToDisplay); This is the error: 1120: Access of undefined property textToDisplay. Do you know how to capture the value of that parameter? Thanks PS: I'm using Adobe Flash CS3 Professional on Windows XP

  • VB.NET Incrementing Indexes

    - by Daniel
    Hello, I am having trouble incrementing the indexes of my list item properties. Here is the code. Dim i As Integer = 0 For x As Integer = 1 To list.Count / 19 database.ExecuteCommand("INSERT INTO Contacts VALUES ('" + _ list.Item(i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "')") Next The ++i does not increment at all in the parameters. Thanks

  • Make SharePoint 2007 List View read-only

    - by FireSnake
    I need to deploy a new List View for the standard List View Web Part in MOSS 2007 via the object model (the list already exists, a new view should be added). I need and want to make this list view read-only. This is because saving changes to the view would corrupt modifications made to Header/Footer. How can I do that via the object model? I looked at the content db, the read-only flag (0x20) is stored with the view and could technically be updated using calls to proc_GetAllWebPartsOnPage and proc_UpdateView[Properties]. NOTE: The database interface and all mentioned stored procs are all documented by Microsoft. Is there ANY way to do that via the object model, because I would strongly prefer that?

  • Unable to import example projects from book (newbie question)

    - by StayWett
    I am trying to import projects from a book "Beginning Android 2" but when I choose the root directory the "Finish" button is still grayed out. I've tried importing the project from scratch with no success, and I've also tried to create a template project with the same name and everything and then importing into that (Import existing projects into workspace) but it always says "No projects are found to import". The contents of the folder are: Res folder, src folder with .java file, the manifest, build, and default.properties files. I am new to android dev (obviously) so I appreciate the help.

  • Facebook Open Graph Debugger Error

    - by Darshanjit Badrain
    Hi I am new to programming and have tried to make a facebook app with open graph beta tutorial. I have done exactly as described in the tutorial but when i try to use the debug tool it gives me an error: Extraneous Property: Objects of this type do not allow properties named og:app_id. I have noticed and searched that its doing this because the tag needs to be <fb:app_id>. I checked my file it says fb:app_id only, but the raw data that pulls up on the debug tool shows meta property="og:app_id" content="267029796703617" even though i have changed and uploaded with fb:app_id. I have checked my page several times and tried some possible solutions but have had no success. Can someone help me fix this.

  • Defining action on window load

    - by zac
    I am trying to get a page to display specific properties depending on whether or not a specific cookie is set... I am trying this var x = readCookie('age'); window.onload=function(){ if (x='null') { document.getElementById('wtf').innerHTML = ""; }; if (x='over13') { document.getElementById('wtf').innerHTML = ""; }; if (x='not13') { document.getElementById('emailBox').innerHTML = "<style type=\"text/css\">.formError {display:none}</style><p>Good Bye</p><p>You must be 13 years of age to sign up.</p>"; }; } It always just defaults to whatever is in the first if statement... I am still learning my javaScript so I am sure this is sloppy.. can someone please help me get this working?

  • Is it possible to use inheritance in this situation? (Java)

    - by they changed my name
    I have ClassA and ClassB, with ClassA being the superclass. ClassA uses NodeA, ClassB uses NodeB. First problem: method parameters. ClassB needs NodeB types, but I can't cast from the subclass to the superclass. That means I can't set properties which are unique to NodeB's. Second problem: When I need to add nodes toClassB, I have to instantiate a new NodeB. But, I can't do this in the superclass, so I'd have to rewrite the insertion to use NodeB. Is there a way around it or am I gonna have to rewrite the whole thing?

  • Sharepoint 2010 search: How to modify search query before submit (programmatically?)

    - by palgo
    Hi, I'm making a custom search box Web Part, similar to the OOTB Web Part from SharePoint (SearchBoxEx class). I'm interested in modifying the search query with additional text before it is submitted, based on a custom checkbox added on the Web Part. Any help on how I can achieve this? UPDATE: I've used the AppendToQuery and AppQueryTerms properties, but this will rewrite the text in the search box as well. I'm interested in passing the values "in the background", maybe as an extra parameter. Point is that the query modification should happen without the user seeing it explicitly.

  • Unit Testing Example, on a class with required fields?

    - by Mastro
    I'm new to developing Unit test and I can't find an example of how to test an existing class I have. The class has a save method which does an insert or update in the database when the user clicks Save in the UI. But the save method has required fields that need to be populated. And has other fields that do not. So how can I run this test properly? Was trying to write it out.. Give a user When user saves object Then Field1 is required then Field2 is required Then Field3 is required WhenUserSavesObject() object = new object object.field1 IsNot Nothing something like that right? And what about the other fields that are optional? How would I test the save method to make sure it takes all those values properly? Was trying to use BDD but not sure if I should try it or not. Can't find any example of classes with many properties that are needed when calling a test method.

  • iPhone : Primitives getters and setters

    - by Burf2000
    I feel a bit miffed at the moment, I done a few iPhone projects that use floats and ints etc and all is fine. I now using OpenGL and GLFloat[] C arrays etc and it seems unless I make methods to set / get them it crashes on the device (not the simulator). Now as these are not setup as properties (I don't think c arrays can) it kind of makes sense. However the project has been working for months without them. It seems something in the code is wiping out anything float / ints to the point that the debugger can see an assigned value but accessing it crashes the phone. As soon as I think I know something for this platform, something changes my mind lol.

  • Is it possible to launch an Android Activity from an AlertDialog?

    - by YYY
    I am trying to create a small pop-up in my Android application to let the user choose from one of many items, ala a ListView. I am hoping to make it show up as a translucent box that overlays on the screen, as opposed to completely occupying it like Activities usually do. One technique for doing this that I've heard is possible is to launch an Activity in an AlertDialog box. This would be perfect - it's the ideal size and has a lot of the mechanical properties I'm looking for, but I'm totally unable to find any more specifics of this technique. Is this possible? And if not, what is the preferred way of accomplishing something like this?

  • C#. Binding object to object

    - by w1z
    Hello all, I develop the part of app functionality. I have the databinding object 'A' and another object 'B'. public class SomeProxy { public SomeProxy(BindingSource A) { var b = new B(); } } public class B { public int SomePropertyFromA{get;set;} //Some autocalculated propeties, that are based on SomePropertyFromA //I want to reculculate them, when the SomePropertyFromA will be changed } 'B' object culculates some values, based on the property 'a' of the 'A' object. I want to bind property in object 'B' to the same property 'a' in 'A'. It's need to handle on changes of the 'a' property, because some UI controls are binded to 'B'-s properties. How can I do this? Sorry for some oddness. Thanks

  • Get name of property as a string

    - by Jim C
    I'm trying to improve the maintainability of some code involving reflection. The app has a .NET Remoting interface exposing (among other things) a method called Execute for accessing parts of the app not included in its published remote interface. Here is how the app designates properties (a static one in this example) which are meant to be accessible via Execute: RemoteMgr.ExposeProperty("SomeSecret", typeof(SomeClass), "SomeProperty"); So a remote user could call: string response = remoteObject.Execute("SomeSecret"); and the app would use reflection to find SomeClass.SomeProperty and return its value as a string. Unfortunately, if someone renames SomeProperty and forgets to change the 3rd parm of ExposeProperty(), it breaks this mechanism. I need to the equivalent of: SomeClass.SomeProperty.GetTheNameOfThisPropertyAsAString() to use as the 3rd parm in ExposeProperty so refactoring tools would take care of renames. Is there a way to do this? Thanks in advance.

  • Rails easy shop

    - by ciss
    I have some question about data organization in my shop. So, after easy mind hacking i decide to create three models: Item, Property and PropertyType Item: id,property_id Property: id, data, property_type_id #(data, serialized object with something like what: {:color => "red", :price => 1000} PropertyType: id, data #(data, also serialized object with {:color => :string, :price => :fixnum}) So, does this good or bad idea? I predict what I can find some problems with validations. But I really need some fields created by user via admin-panel (now I'm talking about Item Properties, which can be changed in any time)

  • How to choose programaticaly the column to be querried by Linq using PropertyInfo???

    - by Richard77
    Hello, I would like to control how linq querries my database programaticaly. For instance, I'd like to querry the column X, column Y, or column Z, depending on some conditions. First of all, I've created an array of all the properties inside my class called myPropertyInfo. Type MyType = (typeOf(MyClass)); PropertyInfo[] myPropertyInfo = myType.GetProperties( BindingFlags.Public|BindingFlags.Instance); the myPropertyInfo array allows me to access each property details (Name, propertyType, etc) through the index*[i]* Now, how can I use the above information to control how linq querries my DB? Here's a sample of a querry I'd like to exploit. var myVar = from tp in db.MyClass select tp.{expression}; Expression using myPropertyInfo[i] to choose which property(column) to querry. I'm not sure if that's the way of doing it, but if there's another way to do so, I'll be glad to learn. Thanks for helping.

  • Project-wide additional library paths -- MSVS2008

    - by sacamano
    Hi there. I'm setting up a VC++ project in MS Visual Studio 2008 that'll be used by several people. I wanted to keep things as simple as possible so I've set up Additional Include Directories via the Project properties. I've also set up additional library files via Tools - Options - Projects and Solutions - VC++ Directories. However, my issue is that I really need to set up Additional library PATHs, because I am using an SDK which does inline linking of libraries. I could just tell each one of the participants to manually add the library path to their MSVS2008 environment, but it would be handy if I could integrate the RELATIVE library path in the project itself.

  • from JS to iphone dev - what's the best language to start with?

    - by Enkai
    I am a total beginner and would like to eventually learn to develop for the iphone. I have just done a beginner's CS course where the language we learned was JavaScript. We studied basic concepts like: variables, arrays, loops (for,while,if,if..else..), properties and functions. I'm wondering if I am starting in the right/wrong place by following this book: Learn C on the Mac by Dave Mark? I have read a few chapters and am finding it a bit hard to get my head around the way that C works, for example the way that Strings are printed seems overly complicated as compared to JS. Do you think that JS was the wrong language to start off with and would I be better to go from JS straight to Objective-C rather than to C? I have tried to read up on previous threads on the merits/demerits of learning C first but haven't found any that relate JS to learning C/Obj C/ Cocoa. Any advice appreciated as I am very new to this. Thanks

  • Gaining Reference to the Dialog from Dialog content

    - by coffeeaddict
    Here's my scenario: I've got a div on Page A. When an event happens (whatever I define, a click, whatever), I do a div.Dialog, set its properties and open it The data inside is returned from an async .ajax call that grabs the data from a url and appends it to the div by calling div.html(data) inside the .ajax callback, so it's essentially loading a PageB by getting the data (content) and appending it to the div that's calling the dialog("open")...nothing special here I don't think. My question: In Page B, how do I reference the dialog so I can do some things to it? For instance in Page B's content that I received back from that .ajax call and added to the div via .html(data), there is a button and when clicked I need to close the dialog. Right now my buttons are not working because one of them closes out the dialog and the other should redirect to a new page but both do not work now because I have no reference to the dialog that it's in to manipulate it.

  • How to access the service instance from host object in WCF?

    - by user1048677
    I am trying to incarnate some sort of ad hoc WCF service. I already managed to launch it and make it call its own web methods as some other guy's methods. The issue that I am facing is instance management. I have set [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)] so it now has a global instance with the same properties for all clients. But besides that I need it to call other services of its kind while listening to incoming requests from clients (similar crazy services). While debugging I noticed that the ServiceHost's constructor calls the constructor of the service class. So, I assumed it has access to the global instance of this class and I need to find a way to call methods of this instance. Please don't ask what I have been smoking, I just have to make it ad hoc.

  • Structure of Astar (A*) graph search data in C#

    - by Shawn Mclean
    How do you structure you graphs/nodes in a graph search class? I'm basically creating a NavMesh and need to generate the nodes from 1 polygon to the other. The edge that joins both polygons will be the node. I'll then run A* on these Nodes to calculate the shortest path. I just need to know how to structure my classes and their properties? I know for sure I wont need to create a fully blown undirected graph with nodes and edges.

  • Property hiding and reflection (C#)

    - by tehMick
    Declaring a property in a derived class that matches the name of a property in the base class "hides" it (unless it overrides it with the override keyword). Both the base and derived class properties will be returned by Type.GetProperties() if their types don't match. However, if their types do match, shockingly only the derived class's property is returned. For instance: class A { protected double p; public int P { get { return (int)p; } set { p = value; } } } class B : A { public new int P { get { return (int)p; } set { p = value; } } } class C : B { public new float P { get { return (float)p; } set { p = value; } } } Calling typeof(C).GetProperties() will only return B.P and C.P. Is it possible to call GetProperties() in a way that returns all three? There is almost certainly a way to do it by traversing the inheritance hierarchy, but is there a cleaner solution?

  • finditem() doesn't find menu, stuck with NullPointerException

    - by fdansv
    I'm stuck while changing some properties on my options menu at onCreateOptionsMenu(). It seems like findItem() returns null, even though I'm pretty sure that the reference to the menu item is correct. My code looks as follows: @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_profile, menu); MenuItem leftie = menu.findItem(R.id.menu_profile); leftie.setIcon(R.drawable.ic_menu_mapmode); leftie.setTitle(R.string.back_map); leftie.setIntent(authIntent); return true; } I really don't know what can be wrong there. Thanks in advance :) EDIT: I forgot to include the actual problem.

  • Fastest method for SQL Server inserts, updates, selects

    - by Ian
    I use SPs and this isn't an SP vs code-behind "Build your SQL command" question. I'm looking for a high-throughput method for a backend app that handles many small transactions. I use SQLDataReader for most of the returns since forward only works in most cases for me. I've seen it done many ways, and used most of them myself. Methods that define and accept the stored procedure parameters as parameters themselves and build using cmd.Parameters.Add (with or without specifying the DB value type and/or length) Assembling your SP params and their values into an array or hashtable, then passing to a more abstract method that parses the collection and then runs cmd.Parameters.Add Classes that represent tables, initializing the class upon need, setting the public properties that represent the table fields, and calling methods like Save, Load, etc I'm sure there are others I've seen but can't think of at the moment as well. I'm open to all suggestions.
