  • BoundingBox Intersection Problems

    - by Deukalion
    When I try to render two cubes, same sizes, one beside the other. With the same proportions (XYZ). My problem is, why do a Box1.BoundingBox.Contains(Box2.BoundingBox) == ContaintmentType.Intersects - when it clearly doesn't? I'm trying to place objects with BoundingBoxes as "intersection" checking, but this simple example clearly shows that this doesn't work. Why is that? I also try checking height of the next object to be placed, by checking intersection, adding each boxes height += (Max.Y - Min.Y) to a Height value, so when I add a new Box it has a height value. This works, but sometimes due to strange behavior it adds extra values when there isn't anything there. This is an example of what I mean: BoundingBox box1 = GetBoundaries(new Vector3(0, 0, 0), new Vector3(128, 64, 128)); BoundingBox box2 = GetBoundaries(new Vector3(128, 0, 0), new Vector3(128, 64, 128)); if (box1.Contains(box2) == ContainmentType.Intersects) { // This will be executed System.Windows.Forms.MessageBox.Show("Intersects = True"); } if (box1.Contains(box2) == ContainmentType.Disjoint) { System.Windows.Forms.MessageBox.Show("Disjoint = True"); } if (box1.Contains(box2) == ContainmentType.Contains) { System.Windows.Forms.MessageBox.Show("Contains = True"); } Test Method: public BoundingBox GetBoundaries(Vector3 position, Vector3 size) { Vector3[] vertices = new Vector3[8]; vertices[0] = position + new Vector3(-0.5f, 0.5f, -0.5f) * size; vertices[1] = position + new Vector3(-0.5f, 0.5f, 0.5f) * size; vertices[2] = position + new Vector3(0.5f, 0.5f, -0.5f) * size; vertices[3] = position + new Vector3(0.5f, 0.5f, 0.5f) * size; vertices[4] = position + new Vector3(-0.5f, -0.5f, -0.5f) * size; vertices[5] = position + new Vector3(-0.5f, -0.5f, 0.5f) * size; vertices[6] = position + new Vector3(0.5f, -0.5f, -0.5f) * size; vertices[7] = position + new Vector3(0.5f, -0.5f, 0.5f) * size; return BoundingBox.CreateFromPoints(vertices); } Box 1 should start at x -64, Box 2 should start at x 64 which means they never overlap. If I add Box 2 to 129 instead it creates a small gap between the cubes which is not pretty. So, the question is how can I place two cubes beside eachother and make them understand that they do not overlap or actually intersect? Because this way I can never automatically check for intersections or place cube beside eachother.

  • Radio Button Web Control Basics in ASP.NET 3.5

    The use of the radio button is widespread in common and basic web applications. Web forms use the radio button to allow the user to select only one option from a list of choices. A common implementation is in surveys. This tutorial will focus on developing web forms that use radio button web controls in ASP.NET 3.5 in Visual Web Developer Express. This is a basic tutorial which should be very useful for new ASP.NET developers who need to learn how to incorporate radio buttons into their ASP.NET projects....

  • SharePoint Scenario Framework

    - by Damon
    I've worked with SharePoint for some time now, and I like to think that I know all there is to know about it.  Deep down I know that's not true, but it's a fun delusion.  However, I found out yesterday that there is a mechanism in SharePoint called the Scenario Framework that has been around for a while but that I had no idea ever existed.  It is used to maintain state between multi-page web forms and helps manage the navigation between those pages.  If building out multiple-page forms in SharePoint is in your plans, you can find more information about the Scenario Framework on Waldek Mastykarz blog entry on the subject.

  • How would I migrate a front page form based site to an IIS7 server? [on hold]

    - by Nick Gilpin
    I have an large html website on a very old server and I'm attempting to move it to a brand new server running IIS7. I've tried moving the entire site to the WWW directory, but then all my forms return "The HTTP verb POST used to access path is not allowed". Additionally, all the solutions I've found online only work on a page by page basis. Is there a simpler/faster way to migrate a large website containing many forms to IIS7? Here is the specific error message: The HTTP verb POST used to access path '/FormServer/Mig/_vti_bin/shtml.dll/admissions/askseaaggie.htm' is not allowed.

  • Web Form Testing [closed]

    - by Frank G.
    I created a application for a client that is along the lines of a ticket tracking system. I wanted to know if anyone know of software that could beta test the web forms. Well I am looking for something that could automatically populate/fill whatever forms are on the web page with generic data. The purpose of this is to just randomly populate data and see if I get any errors on the page when submitted plus to also see how validation for the form functions. Does anyone know of anything that could do this?

  • Creating and using VM Groups in VirtualBox

    - by Fat Bloke
    With VirtualBox 4.2 we introduced the Groups feature which allows you to organize and manage your guest virtual machines collectively, rather than individually. Groups are quite a powerful concept and there are a few nice features you may not have discovered yet, so here's a bit more information about groups, and how they can be used.... Creating a group Groups are just ad hoc collections of virtual machines and there are several ways of creating a group: In the VirtualBox Manager GUI: Drag one VM onto another to create a group of those 2 VMs. You can then drag and drop more VMs into that group; Select multiple VMs (using Ctrl or Shift and click) then  select the menu: Machine...Group; or   press Cmd+U (Mac), or Ctrl+U(Windows); or right-click the multiple selection and choose Group, like this: From the command line: Group membership is an attribute of the vm so you can modify the vm to belong in a group. For example, to put the vm "Ubuntu" into the group "TestGroup" run this command: VBoxManage modifyvm "Ubuntu" --groups "/TestGroup" Deleting a Group Groups can be deleted by removing a group attribute from all the VMs that constitute that group. To do this via the command-line the syntax is: VBoxManage modifyvm "Ubuntu" --groups "" In the VirtualBox Manager, this is more easily done by right-clicking on a group header and selecting "Ungroup", like this: Multiple Groups Now that we understand that Groups are just attributes of VMs, it can be seen that VMs can exist in multiple groups, for example, doing this: VBoxManage modifyvm "Ubuntu" --groups "/TestGroup","/ProjectX","/ProjectY" Results in: Or via the VirtualBox Manager, you can drag VMs while pressing the Alt key (Mac) or Ctrl (other platforms). Nested Groups Just like you can drag VMs around in the VirtualBox Manager, you can also drag whole groups around. And dropping a group within a group creates a nested group. Via the command-line, nested groups are specified using a path-like syntax, like this: VBoxManage modifyvm "Ubuntu" --groups "/TestGroup/Linux" ...which creates a sub-group and puts the VM in it. Navigating Groups In the VirtualBox Manager, Groups can be collapsed and expanded by clicking on the carat to the left in the Group Header. But you can also Enter and Leave groups too, either by using the right-arrow/left-arrow keys, or by clicking on the carat on the right hand side of the Group Header, like this: . ..leading to a view of just the Group contents. You can Leave or return to the parent in the same way. Don't worry if you are imprecise with your clicking, you can use a double click on the entire right half of the Group Header to Enter a group, and the left half to Leave a group. Double-clicking on the left half when you're at the top will roll-up or collapse the group.   Group Operations The real power of Groups is not simply in arranging them prettily in the Manager. Rather it is about performing collective operations on them, once you have grouped them appropriately. For example, let's say that you are working on a project (Project X) where you have a solution stack of: Database VM, Middleware/App VM, and  a couple of client VMs which you use to test your app. With VM Groups you can start the whole stack with one operation. Select the Group Header, and choose Start: The full list of operations that may be performed on Groups are: Start Starts from any state (boot or resume) Start VMs in headless mode (hold Shift while starting) Pause Reset Close Save state Send Shutdown signal Poweroff Discard saved state Show in filesystem Sort Conclusion Hopefully we've shown that the introduction of VM Groups not only makes Oracle VM VirtualBox pretty, but pretty powerful too.  - FB

  • Secretary cannot add appointments to boss's calendar after exchange restore from backup

    - by therulebookman
    The calendar is the Boss's calendar on Exchange. I have set permissions for it through his Outlook to give the secretary and a few other people "Editor" access to his calendar. All the editors can view the calendar, but only he can add new appointments. Anyone else who tries to add an appointment gets "The item cannot be saved in this folder. The folder was deleted or moved or you do not have permission." The permissions are correct, editor. The item hasn't been deleted or moved. It's in his mailbox on exchange. The message says something about the mailbox size, but he is well under the size limit anyway. He is using Outlook 2003, and I have tried accessing it from 2003 and 2007, but I don't think that is related I tried clearing the forms cache and enabling disabled items: no disabled items and clearing cache didn't help. I also tried "Allow all forms" but this apparently doesn't apply in this scenario as we are not using any custom forms. Is there any way to delete just his calendar and then I can exmerge it back in (after exporting to PST of course)? I really can't exmerge out his mailbox, delete it, and exmerge it back in because he works all sorts of hours, but if this is the only way, then I'll have to do it. Is there any other possible solution?

  • NSString variable out of scope in sub-class (iPhone/Obj-C)

    - by Rich
    I am following along with an example in a book with the code exactly as it is in the example code as well as from the book, and I'm getting an error at runtime. I'll try to describe the life cycle of this variable as good as I can. I have a controller class with a nested array that is populated with string literals (NSArray of NSArrays, the nested NSArrays initialized with arrayWithObjects: where the objects are all string literals - @"some string"). I access these strings with a helper method added via a category on NSArray (to pull strings out of a nested array). My controller gets a reference to this string and assigns it to a NSString property on a child controller using dot notation. The code looks like this (nestedObjectAtIndexPath is my helper method): NSString *rowKey = [rowKeys nestedObjectAtIndexPath:indexPath]; controller.keypath = rowKey; keypath is a synthesized nonatomic, retain property defined in a based class. When I hit a breakpoint in the controller at the above code, the NSString's value is as expected. When I hit the next breakpoint inside the child controller, the object id of the keypath property is the same as before, but instead of showing me the value of the NSString, XCode says that the variable is "out of scope" which is also the error I see in the console. This also happens in another sub-class of the same parent. I tried googling, and I saw slightly similar cases where people were suggesting this had to do with retain counts. I was under the impression that by using dot notation on a synthesized property, my class would be using an "auto generated accessor" that would be increasing my retain count for me so that I wouldn't have this problem. Could there be any implications because I'm accessing it in a sub-class and the prop is defined in the parent? I don't see anything in the book's errata about this, but the book is relatively new (Apress - More iPhone 3 Dev). I also have double checked that my code matches the example 100 times.

  • Migrating complex SVN branch hierarchy to Mercurial

    - by Christian Hang
    Our team has been using SVN for managing an application of decent size and over time a rather complex hierarchy of branches and tags has built up, which is following the basic standard layout for SVN repositories, but is more nested: |-trunk |-branches | |-releases | | |-releaseA | | `-releaseB | `-features | |-featureX | `-featureY |-tags |-releaseA | |-beta | `-RTP `-releaseB |-beta `-RTP (The feature branches are obviously temporary branches but we have to take them into consideration as it won't be feasible to close all of them at once in the near future) For several reasons but primarily because merges have been becoming an increasing pain, we are considering to switch to Mercurial. The main problem we are currently facing is migrating the existing code base without losing our history. I've tried several migration tools (e.g., yasvn2hg, hg convert and svn2hg) with yasvn2hg being the most promising, but none of them seem to be able to deal with nested hierarchies but they all assume that branches and tags are organized in one flat directory respectively. The choice between named branches or clones as the conversion target of old SVN branches is not a limiting factor in this case, as either solution would be appreciated. We are currently experimenting with both options and how they would fit into our current processes but haven't decided on one yet. I'd obviously be interested in recommendations or experiences with similar setups concerning that issue as well. So, what is the best way to convert a nested SVN branch hierarchy like this to Mercurial? Converting one branch at a time into a separate repository would be quite annoying and I am not sure if that would be the right approach in the first place, depending on how the tools handle historic merges and need to be aware of all other branches?

  • Recursion in an ASP.NET MVC view

    - by Dennis Palmer
    I have a nested data object for a set of items within categories. Each category can contain sub categories and there is no set limit to the depth of sub categories. (A file system would have a similar structure.) It looks something like this: class category { public int id; public string name; public IQueryable<category> categories; public IQueryable<item> items; } class item { public int id; public string name; } I am passing a list of categories to my view as IQueryable<category>. I want to output the categories as a set of nested unordered list (<ul>) blocks. I could nest foreach loops, but then the depth of sub categories would be limited by the number of nested foreach blocks. In WinForms, I have done similar processing using recursion to populate a TreeView, but I haven't seen any examples of using recursion within an ASPX MVC view. Can recursion be done within an ASPX view? Are there other view engines that include recursion for view output?

  • C++ behavior of for loops vs. while loops

    - by kjh
    As far as I understand, when you write a for-loop similar to this one for (int i = 0; i < SOME_NUM; i++) { if (true) do_something(); else do_something_else(); } The time complexity of this operation is mostly affected by the if (true) statement because the for-loop iterations don't actually involve any comparisons of i to SOME_NUM, the compiler will just essentially run the code inside the for-loop SOME_NUM times. Please correct me if I am wrong. However if this is correct, then how do the following nested for-loops behave? for (int i = 0; i < SOME_NUM; i++) { for (int j = 0; j < i; j++) { do_something(); } } The j in the inner for-loop is now upper bound by i, a value that changes every time the loop restarts. How will the compiler compile this? Do these nested for-loops essentially behave like a for-loop with while-loop inside of it? If you're writing an algorithm that uses nested for-loops where the inner counting variable depends on the outer counting variable should you be concerned about what this will do to the complexity of your algorithm?

  • Java Swingworker: Not as encapsulated class

    - by Thomas Matthews
    I'm having problems passing information, updating progress and indicating "done" with a SwingWorker class that is not an encapsulated class. I have a simple class that processes files and directories on a hard drive. The user clicks on the Start button and that launches an instance of the SwingWorker. I would like to print the names of the files that are processed on the JTextArea in the Event Driven Thread from the SwingWorker as update a progress bar. All the examples on the web are for an nested class, and the nested class accesses variables in the outer class (such as the done method). I would also like to signal the Event Driven Thread that the SwingWorker is finished so the EDT can perform actions such as enabling the Start button (and clearing fields). Here are my questions: 1. How does the SwingWorker class put text into the JTextArea of the Event Driven Thread and update a progress bar? How does the EDT determine when the {external} SwingWorker thread is finished? {I don't want the SwingWorker as a nested class because there is a lot of code (and processing) done.}

  • Jasper Reports- Error instantiating extensions registry for chart.theme

  • Why can I run JUnit tests for my Spring project, but not a main method?

    - by FarmBoy
    I am using JDBC to connect to MySQL for a small application. In order to test without altering the real database, I'm using HSQL in memory for JUnit tests. I'm using Spring for DI and DAOs. Here is how I'm configuring my HSQL DataSource <bean id="mockDataSource" class="org.springframework.jdbc.datasource.SingleConnectionDataSource"> <property name="driverClassName" value="org.hsqldb.jdbcDriver"/> <property name="url" value="jdbc:hsqldb:mem:mockSeo"/> <property name="username" value="sa"/> </bean> This works fine for my JUnit tests which use the mock DB. But when I try to run a main method, I find the following error: Error creating bean with name 'mockDataSource' defined in class path resource [beans.xml]: Error setting property values; nested exception is org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions (1) are: PropertyAccessException 1: org.springframework.beans.MethodInvocationException: Property 'driverClassName' threw exception; nested exception is java.lang.IllegalStateException: Could not load JDBC driver class [org.hsqldb.jdbcDriver] I'm running from Eclipse, and I'm using the Maven plugin. Is there a reason why this would work as a Test, but not as a main()? I know that the main method itself is not the problem, because it works if I remove all references to the HSQL DataSource from my Spring Configuration file.

  • Serialization Performance and Google Android

    - by Jomanscool2
    I'm looking for advice to speed up serialization performance, specifically when using the Google Android. For a project I am working on, I am trying to relay a couple hundred objects from a server to the Android app, and am going through various stages to get the performance I need. First I tried a terrible XML parser that I hacked together using Scanner specifically for this project, and that caused unbelievably slow performance when loading the objects (~5 minutes for a 300KB file). I then moved away from that and made my classes implement Serializable and wrote the ArrayList of objects I had to a file. Reading that file into the objects the Android, with the file already downloaded mind you, was taking ~15-30 seconds for the ~100KB serialized file. I still find this completely unacceptable for an Android app, as my app requires loading the data when starting the application. I have read briefly about Externalizable and how it can increase performance, but I am not sure as to how one implements it with nested classes. Right now, I am trying to store an ArrayList of the following class, with the nested classes below it. public class MealMenu implements Serializable{ private String commonsName; private long startMillis, endMillis, modMillis; private ArrayList<Venue> venues; private String mealName; } And the Venue class: public class Venue implements Serializable{ private String name; private ArrayList<FoodItem> foodItems; } And the FoodItem class: public class FoodItem implements Serializable{ private String name; private boolean vegan; private boolean vegetarian; } IF Externalizable is the way to go to increase performance, is there any information as to how java calls the methods in the objects when you try to write it out? I am not sure if I need to implement it in the parent class, nor how I would go about serializing the nested objects within each object.

  • Groovy on Grails: GORM and BitSets?

    I don't see anything in the official documentation about unsupported persistence data types, so I'm working under the assumption that types available in the Groovy language should be handled. However, for the following domain class: class DocGroupPermissions { Workgroup workgroup; Document document; BitSet permissions = new BitSet(2) public DocGroupPermissions() {} void setPermissions(boolean canRead, boolean canWrite){ setReadPermissions(canRead) setWritePermissions(canWrite) } BitSet getPermissions() { return permissions } void setReadPermissions(boolean canRead) { permissions.set(0,canRead) } void setWritePermissions(boolean canWrite) { permissions.set(1,canWrite) } boolean getReadPermissions() { return permissions.get(0) } boolean getWritePermissions() { return permissions.get(1) } static belongsTo = [workgroup:Workgroup, document:Document] static constraints = { workgroup(nullable:false, blank:false) document(nullable:false, blank:false) } } I'm getting: 2009-11-15 16:46:12,298 [main] ERROR context.ContextLoader - Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'messageSource': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager': Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory': Invocation of init method failed; nested exception is org.hibernate.MappingException: An association from the table doc_group_permissions refers to an unmapped class: java.util.BitSet Has anyone run into this before?
