  • What is the easiest way to create a clickable grid for a game in C++?

    - by mangoman13
    I haven't used C++ in a while, so I decided to take on a small project to become familiar with it again. I am trying to make a chinese checkers game, but I have no experience with GUI design in C++. Is there a real simple way to just make grid (i.e. bitmap hexagons or something) that when clicked on, will give me the index number of the one I've clicked on? If someone has any examples of how to do this, even with just a 2D grid of squares, that would be helpful. Any help is appreciated, thanks!

  • VS2010 Database Compare. How do you create a *.DBSchema extensioned file?

    - by George
    I'd like to take a snapshot of my database, make some changes and then use the db compare functionality to identify the changes, and who knows, maybe even generate scripts to make the change. I'd like to avoid having to backup the current db and restore it as a separate db just to have a "before" snapshot. I'm guessing I shouldn't have to. Obsviously, I'm clueless about db projects and am looking to be pointed in the right direction. ty!

  • How to decide if a parameter is the click event

    - by sameold
    I have a function which can be called by either a click event or directly. When I call it directly, I need pass it a data parameter, so I've defined the function to accept a parameter to account for the direct call with the parameter. function myFunc(param){ } Within the function, I need to differentiate whether the function was called directly or from the click event, so what I thought I could simply check if param is set. If it's set, then the function is called directly. If it's not set, then it's called from the click event. The problem is that a click event by default passes an event object. So even when the function is called by the click event, param won't be null. So is there a way to check whether the param passed is the click event?

  • Is it possible to create a sub window which will not deactivate the parent?

    - by Bob
    Normally when creating a sub window (WS_POPUP), the child window will become activate and the parent will become deactivated. However, with menus, both remain active. At least I am assuming the menu is active, it at least has focus. Example: Click on the file menu in notepad, the menu appears, yet the notepad window still looks active. Is it possible to mirror this behavior with either a window style or responding to a particular message? Thanks Another example: Combo boxes seem to show a subwindow, yet do not deactivate the window. And you can click on that subwindow, while still maintaining an activate main window. Any ideas on how to grab the class /style of that window?

  • Can I create an xml that specifies element from 2 nested xsd's without using a prefixes?

    - by TweeZz
    I have 2 xsd's which are nested: DefaultSchema.xsd: <?xml version="1.0" encoding="utf-8"?> <xs:schema id="DefaultSchema" targetNamespace="http://myNamespace.com/DefaultSchema.xsd" elementFormDefault="qualified" xmlns="http://myNamespace.com/DefaultSchema.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" > <xs:complexType name="ZForm"> <xs:sequence minOccurs="0" maxOccurs="unbounded"> <xs:element name="Part" minOccurs="0" maxOccurs="unbounded" type="Part"/> </xs:sequence> <xs:attribute name="Title" use="required" type="xs:string"/> <xs:attribute name="Version" type="xs:int"/> </xs:complexType> <xs:complexType name="Part"> <xs:sequence minOccurs="0" maxOccurs="unbounded"> <xs:element name="Label" type="Label" minOccurs="0"></xs:element> </xs:sequence> <xs:attribute name="Title" use="required" type="xs:string"/> </xs:complexType> <xs:complexType name="Label"> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute name="Title" type="xs:string"/> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:schema> ExportSchema.xsd: (this one kinda wraps 1 more element (ZForms) around the main element (ZForm) of the DefaultSchema) <?xml version="1.0" encoding="utf-8"?> <xs:schema id="ExportSchema" targetNamespace="http://myNamespace.com/ExportSchema.xsd" elementFormDefault="qualified" xmlns="http://myNamespace.com/DefaultSchema.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:es="http://myNamespace.com/ExportSchema.xsd" > <xs:import namespace="http://myNamespace.com/DefaultSchema.xsd" schemaLocation="DefaultSchema.xsd"/> <xs:element name="ZForms" type="es:ZFormType"></xs:element> <xs:complexType name="ZFormType"> <xs:sequence> <xs:element name="ZForm" type="ZForm" maxOccurs="unbounded" /> </xs:sequence> </xs:complexType> </xs:schema> And then finally I have a generated xml: <?xml version="1.0" encoding="utf-8"?> <ZForms xmlns="http://myNamespace.com/ExportSchema.xsd"> <ZForm Version="1" Title="FormTitle"> <Part Title="PartTitle" > <Label Title="LabelTitle" /> </Part> </ZForm> </ZForms> Visual studio complains it doesn't know what 'Part' is. I was hoping I do not need to use xml namespace prefixes (..) to make this xml validate, since ExportSchema.xsd has a reference to the DefaultSChema.xsd. Is there any way to make that xml structure valid without explicitly specifying the DefaultSchema.xsd? Or is this a no go?

  • Variable scope problem in JavaScript

    - by dfjhdfjhdf
    I declare a variable with the var word inside a function that handles Ajax requests, then later on in the function I have another function that should change the value of the variable but - my problem - it fails. How to settle the problem down? Here's similiar code I use: function sendRuest(someargums) { /* some code */ var the_variable; /* some code */ //here's that other function request.onreadystatechange = function() { if (request.readyState == 4) { switch (request.status) { case 200: //here the variable should be changed the_variable = request.responseXML; /* a lot of code */ //somewhere here the function closes } return the_variable; } var data = sendRequest(someargums); //and trying to read the data I get the undefined value

  • Call methods on native Javascript types without wrapping with ()

    - by Anurag
    In Javascript, we can call methods on string literals directly without enclosing it within round brackets. But not for other types such as numbers, or functions. It is a syntax error, but is there a reason as to why the Javascript lexer needs these other types to be enclosed in round brackets? For example, if we extend Number, String, and Function with an alert method and try calling this method on the literals, it's a SyntaxError for Number and Function, while it works for a String. function alertValue() { alert(this); } Number.prototype.alert = alertValue; String.prototype.alert = alertValue; Function.prototype.alert = alertValue; We can call alert directly on a string object: "someStringLiteral".alert() // alerts someStringLiteral but it's a SyntaxError on numbers, and functions. 7.alert(); function() {}.alert(); To work with these types, we have to enclose it within brackets: (7).alert(); // alerts "7" (function() {}).alert(); // alerts "function() {}"

  • Percentage function for a group based on another group.

    - by Jeff O
    I have two grouping levels in a report. Group A can have a Percentage() of the entire report and so can Group B, but I would like to know the Percentage() of Group A of Group B. Even if I code it, it seems like once the inner and outer groups have created their footers, I can't go back to to the inner group and set it's value. Example: Group A Total 50 Group A percentage of Report Total = 33% Group A Percentage of Group B Total = 33% but I want 50% Group B Total 100 Group B Percentage of Report Total = 66% Report Total 150

  • How do i create these borders in the middle?

    - by Nitesh Panchal
    Hello, I know how to generate rounded corners using images. But please have a look at the link :- http://roundedbox.andreas-kalt.de/ The rounded corners on all four corners are all images, but my question is how are those borders in the middle done? Those green color borders that surround the whole div. The tutorial is given but it is German :(. Also i don't want to use Css3 like -webkit-border-radius etc as they are not yet supported in IE Thanks in advance :)

  • How can one enforce calling a base class function after derived class constructor?

    - by Mike Elkins
    I'm looking for a clean C++ idiom for the following situation: class SomeLibraryClass { public: SomeLibraryClass() { /* start initialization */ } void addFoo() { /* we are a collection of foos */ } void funcToCallAfterAllAddFoos() { /* Making sure this is called is the issue */ } }; class SomeUserClass : public SomeLibraryClass { public: SomeUserClass() { addFoo(); addFoo(); addFoo(); // SomeUserClass has three foos. } }; class SomeUserDerrivedClass : public SomeUserClass { public: SomeUserDerrivedClass() { addFoo(); // This one has four foos. } }; So, what I really want is for SomeLibraryClass to enforce the calling of funcToCallAfterAllAddFoos at the end of the construction process. The user can't put it at the end of SomeUserClass::SomeUserClass(), that would mess up SomeUserDerrivedClass. If he puts it at the end of SomeUserDerrivedClass, then it never gets called for SomeUserClass. To further clarify what I need, imagine that /* start initialization */ acquires a lock, and funcToCallAfterAllAddFoos() releases a lock. The compiler knows when all the initializations for an object are done, but can I get at that information by some nice trick?

  • How to create a separate thread to do some operation periodically and update UI in WPF?I'm stack

    - by black sensei
    Hello Experts! I'm trying to do a periodic separated thread operation let's say check for internet connection or check for user's info via web service and update the user interface. i've tried with quartz.net to implement that.So i created an inner class for the window i need to update.That inner class does what is meant for but the problem is that i don't know how to access parent's(window class) members form the child(inner class). for example public partial class Window2 : Window { private int i; public Window2() { InitializeComponent(); } public string doMyOperation() { //code here return result; } public class Myclass :IJob { public void Execute(JobExecutionContext context) { string result = doMyOperation(); //Now here i could be able to call a label of name lblNotif //lblNotif.Content = result; } } } Well the whole idea works but i'm stacked at here i need to access a controls of Window2 Since i'm stacked i tried Spring.Net way of implementing Quartz hoping that i could use MethodInvokingJobDetailFactoryObject and rather have the Operation done on Window2 itself.But for some reason i'm having an exception Cannot resolve type [System.Windows.Window2,System.Windows];, could not load type from string value System.Windows.Window2,System.Windows and the wiring is done so <object name="UpdateLabelJob" type="System.Windows.Window2,System.Windows"/> What i'm i doing wrong here?Is that a way round? thanks for reading and for helping out

  • OSGi bundle imports packages from non-bundle jars: create bundles for them?

    - by John Simmons
    I am new to OSGi, and am using Equinox. I have done several searches and can find no answer to this. The discussion at OSGI - handling 3rd party JARs required by a bundle helps somewhat, but does not fully answer my question. I have obtained a jar file, rabbitmq-client.jar, that is already packaged as an OSGi bundle (with Bundle-Name and other such properties in its MANIFEST.MF), that I would like to install as a bundle. This jar imports packages org.apache.commons.io and org.apache.commons.io.input from commons-io-1.2.jar. The RabbitMQ client 2.7.1 distribution also includes commons-cli-1.1.jar, so I presume that it is required as well. I examined the manifests of these commons jars and found that they do not appear to be packaged as bundles. That is, their manifests have none of the standard bundle properties. My specific question is: if I install rabbitmq-client.jar as a bundle, what is the proper way to get access to the packages that it needs to import from the commons jars? There are only three alternatives that I can think of, without rebuilding rabbitmq-client.jar. The packages from the commons jars are already included in the Equinox global classpath, and rabbitmq-client.jar will get them automatically from there. I must make another bundle with the two commons jars, export the needed packages, and install that bundle in Equinox. I must put these two commons jars in the global classpath when I start Equinox, and they will be available to rabbitmq-client.jar from there. I have read that one normally does not use the global classpath in an OSGi container. I am not clear on whether items from the global classpath are even available when building individual bundle classpaths. However, I note that rabbitmq-client.jar also imports other packages such as javax.net, which I presume come from the global classpath. Or is there some other bundle that exports them? Thanks for any assistance!

    New to Android need help with one solid build that I can refer to and study for future projects. The first activity is a background image with a button,when clicked the it takes you to the second activity which is a form with 5 data fields and 2 buttons. One button calls an intent to take a picture within the app and one button that submits the data from the form along with the picture to URL. lastly a third activity that says complete thank you. I can make some of this but don't know how to link button or open and merge camera with the app to be sent as a package of data.
