  • Tile Collision Question

    - by Alu
    Hey guys, I'm working on tile collision. Currently, I just draw the tile map the normal way (two for loops) and there is no scrolling. Right now, to check if my player is over a tile, I use tileX = (int)person1v.X / 16; tileY = (int)person1v.Y / 16; However, I want to detect collision before I hit the tile so it could act as a wall. How do I detect collision before even making the move?

  • Setting Vertical-Align for a button

    - by danish
    I have a in a user control. In that, I have added a HTML table in which there is a button. I need to have the buttons aligned to the bottom of the cell. I tried setting the property in the CSS file the style does not gets applied. What is it that I am doing wrong? ASCX file: <link href="CSSFile.css" rel="stylesheet" type="text/css" /> . . . <td> <asp:Button ID="btnOK" runat="server" Text="OK" Width="66px" CssClass="ButtonClass"/> <asp:Button ID="btnClose" runat="server" Text="Close" Width="66px"/> </td> CSS File: ButtonClass { border: thin groove #000000; vertical-align: bottom; color: #000000; background-color: #99FFCC; } The CSS file and the user control reside in the same folder.

  • InvalidCastException when getting Text from a Label referenced by dynamicaly built String, Fix?

    - by Chris
    NET Version: 3.5 Ok, I recieve an error (System.InvalidCastException was unhandled. Message="Unable to cast object of type 'System.Windows.Forms.Control[]' to type 'System.Windows.Forms.Label'.") when trying to get Text from a Label referenced by a dynamicly built string. Here's my situation; I have an array of 250 labels named l1 - l250. What I want to do is loop through them using this while statement: int c = 1; while (c < 251) { string k = "l" + c.ToString(); //dynamic name of Control(Label) object ka = Controls.Find(k, true); string ct = ((Label)ka).Text; //<<Error Occurs Here build = build + ct; c++; } and get the text value of each to build a string named build. I don't get any build errors, just this while debuging. While debuging I can go down to view my local variables. When looking through these, I can view the contents of object ka; it does contain the correct Text value of the correct Label I want to "access". I just don't understand how to get there. The text value is listed under "[0]" which is the only subcatagory for "ka".

  • UML diagram for application architecture?

    - by fayer
    i'm trying to map my whole application in a UML diagram and i wonder what diagram type i should use. im not doing this in class level, rather from a bird eye's perspective. single application object (patterns: singleton)(examples: CodeIgniter application) that composes multiple module objects (patterns: singleton, facades)(examples: guestbook, addressbook) that compose multiple low level stand alone objects (examples: mysql mapper, doctrine mapper) that compose various 3rd and in-house libraries (examples: doctrine, solr, xml-parser) what UML diagram is suited for this kind of overview presentation? thanks

  • entity framework vNext wish list

    - by Fred Yang
    I have been intensively studying and use ef4 in my project. I do feel the improvement that it has over version 1. But I found that I have something I cannot get around easily. Here is a list I want it to be better in ef vNext. the model designer should allow multiple view of the same model, so that I don't need cram all my entity into a single view. respect user's manual edit of edmx. Currently, the some database view object simply can not be imported to the model because the designer "smartly" think that the view does not have a primary key, so that I have to manually edit the edmx to correct designer's behavior. But in the next "update from database" task, designer will revert my customization. For now, I simply fallback to manually edit the edmx file at all, or I have to use compare tool to keep the new update, and rollback and put the new update into my old edmx file manually. Designer should be improved to allow default behavior and user's manual control. I want control not to let the designer refresh the change of imported object. support user defined table function. linq is about Composability, stored proc dos not support composability. I wish I could use user defined table function which support this. What are you wishes for EF vNext?

  • .NET ValidationRule problem

    - by PaN1C_Showt1Me
    Hi ! I have a control with this validation <MyPicker.SelectedItem> <Binding Path="Person.Value" Mode="TwoWay" UpdateSourceTrigger="PropertyChanged" NotifyOnValidationError="True"> <Binding.ValidationRules> <rules:MyValidationRule ValidationType="notnull"/> </Binding.ValidationRules> </Binding> </MyPicker.SelectedItem> This is the Validation Class: class MyValidationRule : ValidationRule { private string _validationType; public string ValidationType { get { return _validationType; } set { _validationType = value; } } public override ValidationResult Validate(object value, CultureInfo cultureInfo) { ValidationResult trueResult = new ValidationResult(true, null); switch (_validationType.ToLower()) { case "notnull": return value == null ? new ValidationResult(false, "EMPTY FIELD") : trueResult; default: return trueResult; } } } Question: When the property is changed, then the Validate( ) method is called which is correct. But to call this method at the very beginning when the MyControl is created? I need to prove immediate after initialize if the there's a null value in the control (and display a validation error)

  • Disposing ActiveX resources owned by another thread

    - by Stefan Teitge
    I've got a problem problem with threading and disposing resources. I've got a C# Windows Forms application which runs expensive operation in a thread. This thread instantiates an ActiveX control (AxControl). This control must be disposed as it uses a high amount of memory. So I implemented a Dispose() method and even a destructor. After the thread ends the destructor is called. This is sadly called by the UI thread. So invoking activexControl.Dispose(); fails with the message "COM object that has been separated from its underlying RCW", as the object belongs to another thread. How to do this correctly or is it just a bad design I use? (I stripped the code down to the minimum including removing any safety concerns.) class Program { [STAThread] static void Main() { // do stuff here, e.g. open a form new Thread(new ThreadStart(RunStuff); // do more stuff } private void RunStuff() { DoStuff stuff = new DoStuff(); stuff.PerformStuff(); } } class DoStuff : IDisposable { private AxControl activexControl; DoStuff() { activexControl = new AxControl(); activexControl.CreateControl(); // force instance } ~DoStuff() { Dispose(); } public void Dispose() { activexControl.Dispose(); } public void PerformStuff() { // invent perpetuum mobile here, takes time } }

  • relative url in wcf service binding

    - by Jeremy
    I have a silverlight control which has a reference to a silverlight enabled wcf service. When I add a reference to the service in my silverlight control, it adds the following to my clientconfig file: <configuration> <system.serviceModel> <bindings> <basicHttpBinding> <binding name="BasicHttpBinding_DataAccess" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"> <security mode="None" /> </binding> </basicHttpBinding> </bindings> <client> <endpoint address="http://localhost:3097/MyApp/DataAccess.svc" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_DataAccess" contract="svcMyService.DataAccess" name="BasicHttpBinding_DataAccess" /> </client> </system.serviceModel> </configuration> How do I specify a relative url in the endpoint address instead of the absolute url? I want it to work no matter where I deploy the web app to without having to edit the clientconfig file, because the silverlight component and the web app will always be deployed together. I thought I'd be able to specify just "DataAccess.svc" but it doesn't seem to like that.

  • Changing tabs in android

    - by Pavel
    Hi guys. Can someone please tell me how to change tab by clicking on element INSIDE the tab? I already tried it with global data. The code looks like this: public class Tabs extends TabActivity { int tabNumber = 0; private TabHost tabHost; int returnedTabNumber = 0; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Resources res = getResources(); // Resource object to get Drawables tabHost = getTabHost(); // The activity TabHost TabHost.TabSpec spec; // Resusable TabSpec for each tab Intent intent; // Reusable Intent for each tab // Create an Intent to launch an Activity for the tab (to be reused) intent = new Intent().setClass(this, Tribocracy.class); // Initialize a TabSpec for each tab and add it to the TabHost spec = tabHost.newTabSpec("map").setIndicator("Map", res.getDrawable(R.drawable.ic_tab_artists)) .setContent(intent); tabHost.addTab(spec); // Do the same for the other tabs intent = new Intent().setClass(this, Areas.class); spec = tabHost.newTabSpec("areas").setIndicator("Areas", res.getDrawable(R.drawable.ic_tab_albums)) .setContent(intent); tabHost.addTab(spec); // Do the same for the other tabs intent = new Intent().setClass(this, Settings.class); spec = tabHost.newTabSpec("settings").setIndicator("Settings", res.getDrawable(R.drawable.ic_tab_albums)) .setContent(intent); tabHost.addTab(spec); tabHost.setCurrentTab(tabNumber); } protected void onResume() { super.onResume(); GlobalData globalData = ((GlobalData)getApplicationContext()); returnedTabNumber = globalData.getTabNumber(); tabHost.setCurrentTab(returnedTabNumber); } } The global adapter looks like this: public class GlobalData extends Application { //---------------------------------------------------- private int Point1; //define the vars here private int Point2; //define the vars here private int Point3; //define the vars here private int Point4; //define the vars here private int Point5; //define the vars here private int Point6; //define the vars here private int tabNumber; public int getTabNumber() //getter of the value { return tabNumber; } public int setTabNumber(int number) //setter of the value { tabNumber = number; return tabNumber; } } Now when I'm trying to change tab in my ListActivity tab by clicking on one of the items it doesn't do anything and stays on the ListActivity tab. Perhaps I shouldn't use onResume() here. Basically I want to go to first tab when I click on one of the items in the list. Please help!

  • Abstract mapping with custom JiBX marshaller

    - by aweigold
    I have created a custom JiBX marshaller and verified it works. It works by doing something like the following: <binding xmlns:tns="http://foobar.com/foo" direction="output"> <namespace uri="http://foobar.com/foo" default="elements"/> <mapping class="java.util.HashMap" marshaller="com.foobar.Marshaller1"/> <mapping name="context" class="com.foobar.Context"> <structure field="configuration"/> </mapping> </binding> However I need to create multiple marshallers for different HashMaps. So I tried to reference it with abstract mapping like this: <binding xmlns:tns="http://foobar.com/foo" direction="output"> <namespace uri="http://foobar.com/foo" default="elements"/> <mapping abstract="true" type-name="configuration" class="java.util.HashMap" marshaller="com.foobar.Marshaller1"/> <mapping abstract="true" type-name="overrides" class="java.util.HashMap" marshaller="com.foobar.Marshaller2"/> <mapping name="context" class="com.foobar.Context"> <structure map-as="configuration" field="configuration"/> <structure map-as="overrides" field="overrides"/> </mapping> </binding> However when doing so, when I attempt to build the binding, I receive the following: Error during code generation for file "E:\project\src\main\jibx\foo.jibx" - this may be due to an error in your binding or classpath, or to an error in the JiBX code My guess is that either I'm missing something I need to implement to enable my custom marshaller for abstract mapping, or custom marshallers do not support abstract mapping. I have found the IAbstractMarshaller interface in the JiBX API (http://jibx.sourceforge.net/api/org/jibx/runtime/IAbstractMarshaller.html), however the documentation seems unclear to me on if this is what I need to implement, as well as how it works if so. I have not been able to find an implementation of this interface to work off of as an example. My question is, how do you do abstract mapping with custom marshallers (if it's possible)? If it is done via the IAbstractMarshaller interface, how does it work and/or how should I implement it?

  • assign member based on string value

    - by Aperion
    I need start off with code because I am not sure what terminology to use. Lets say I have the following code: class Node { public: void Parse(rapidxml::xml_node<> *node) { for (rapidxml::xml_attribute<> *attr = node->first_attribute(); attr; attr = attr->next_attribute()) { std::stringstream converter; converter << attr->value(); if( !strcmp(attr->name(), "x") ) converter >> x; else if( !strcmp(attr->name(),"y") ) converter >> y; else if( !strcmp(attr->name(), "z") ) converter >> z; } } private: float x; float y; float z; }; What I can't stand is the repetition of if( !strcmp(attr-name(), "x") ) converter x; I feel that this is error prone and monotonous, but I cannot think of another way to map a string value to a member assignment. What are some other approaches one can take to avoid code such as this? The only other possible alternative I could think of was to use a hashmap, but that runs into problems with callbacks This is the best I could up with but it's not as flexible as I'd like: class Node { Node() : x(0.0f), y(0.0f), z(0.0f) { assignmentMap["x"] = &x; assignmentMap["y"] = &y; assignmentMap["z"] = &z; } public: void Parse(rapidxml::xml_node<> *node) { for (rapidxml::xml_attribute<> *attr = node->first_attribute(); attr; attr = attr->next_attribute()) { if( !attr->name() ) continue; std::stringstream converter; converter << attr->value(); converter >> *assignmentMap[attr->name()]; } } private: float x; float y; float z; std::map<std::string, float*> assignmentMap; };

  • How to best launch C++ application from web page

    - by JB
    I guess there are two parts to this question, one technical and one best practice for security and doing things "right". I'm working on a little game using C++ / directx but I would like to be able to launch it from a web page by someone clicking on a link on that page. Ideally I would like the first time they clicked for it to launch an installer downloads and installs the game on their machine, and then the next time to launch an application which updates the game from a web site if it's old and then launches it. I have no problems with the expected security popups and questions the first time it runs. I want people to be certain what they are installing and understand what they are doing. But it would be nice if once it is installed they could run it with the minimum of fuss. My question then is what technologies I could use to do this? I'm thinking that it would need a browser plugin and an activex control so that first time you'd install that, and subsequently the control/plugin would be able to launch the game. I'm not sure that under newer browser secuity models that a plugin would have the permissions to be able to run an installer though or silently invoke applications on the client machine even if they are already installed. Is there a more sensible way to achive what I want to achieve? And I'm worried about the security aspects too. I want this to be convenient for users but I of course want to do it "right". I know this can be done as I've seen several mmorpg type games that launch in this way from the browser now but it's not entirely clear to me how they've done it.

  • How to create javascript object from form elements using jQuery

    - by ob
    I'd like to be able to create a javascript object from my html form and am wondering if there's a good way to do this using jquery. I guess what i'm looking for is something similar to $.serialize, but which would result in a map instead of a string. <form> <input type="text" name="foo1" value="bar1" /> <input type="text" name="foo2" value="bar2" /> </form> desired result: { foo1:"bar1", foo2:"bar2" }

  • Controlling Movie Clips from the main time line instead of using their individual time lines?

    - by Jess
    I have a Flash website template (four pages) that I made using AS 3.0 and Flash CS4. It is for an assignment involving movie clips. Currently on the main time line there is only one frame, and three layers: actions/menu/content. The actionscript on the main time line is simply: content_mc.stop (); There is a movie clip on the stage called “Content” that contains the content for each of the pages. Inside of that there is a “Menu” movie clip that contains and controls all of the navigation buttons. The actionscript for the Menu movie clip is: function homeBtnPress (event:MouseEvent):void{ //comments here //comments here MovieClip(parent).content_mc.gotoAndStop("home"); } function aboutBtnPress (event:MouseEvent): void{ MovieClip(parent).content_mc.gotoAndStop ("about"); } function servicesBtnPress (event:MouseEvent): void{ MovieClip (parent).content_mc.gotoAndStop ("services"); } function contactBtnPress (event:MouseEvent): void{ MovieClip (parent).content_mc.gotoAndStop ("contact"); } function portfolioBtnPress (event:MouseEvent): void{ MovieClip (parent).content_mc.gotoAndStop ("portfolio"); } home.addEventListener(MouseEvent.CLICK, homeBtnPress); about.addEventListener(MouseEvent.CLICK, aboutBtnPress); services.addEventListener(MouseEvent.CLICK, servicesBtnPress); contact.addEventListener(MouseEvent.CLICK, contactBtnPress); portfolio.addEventListener(MouseEvent.CLICK, portfolioBtnPress); So everything works fine, but my instructor wants me to control the menu/content from the main time line by using the target path tool. What exactly would I target – just the “menu” and “content” movie clips, and what code would I use? Sorry if I'm not explaining very well, I'm pretty confused. Here is the feedback from my instructor: “While we learned how to control the main timeline and the timeline of another movie clip from within a movie clip, this is not the most intuitive way to script and makes for difficult debugging. So you will need to explore how to target your buttons inside of your menu movie clip and the frames within the content movie clip from the main timeline. “ Thanks so much in advance!

  • Reading in a 5000 line text file on the Iphone

    - by howsyourface
    Gday, I am trying to create a tiled map for my game, i have had this previously working using other xml methods but i had memory leaks and all sorts of errors. However i had a map load time of about 2.5 - 3 seconds. So i rewrote all of the code using NSMutableStrings and NSStrings. After my best attempt at optomizing it i had a map load time of 10 - 11 seconds, which is far too slow. So i have now rewritten the code using char* arrays, only to now have a load time of 18 seconds -_-. Here is the latest code, i don't know much c so i could have easily botched the whole thing up.

return index; } (I know it's a lot of code to be putting in here) I thought the by using basic char arrays i could drastically increase the performance, at least over the initial node based code that i was replacing. Thanks for all your efforts.
