  • Basic Java drawing program: issue with squares

    - by Caminek
    I'm trying to create a simple drawing program that creates a square where the user clicks and drags. The square displays correctly as long as either x or y remain positive with respect to the original click position. If both x and y are negative with respect to the original click position, the square grows/shrinks, but also wanders about the screen. Is there a way to swap the origin point from top-left to bottom-right or to keep the square from wandering?

  • What personal milestones can you use to measure growth in your programming abilities?

    - by GWLlosa
    How can you determine objectively, over time, that you are getting any better at producing code? For example, I may sit here and feel that "I know now, and I use now, so I must be better." But this does not account for my own bias, or the fact that I may be getting better at a slower rate than intended, or I may actually suck at and not realize it. What methods are available for one to objectively rate one's own abilities? What about to objectively compare them to their peer groups?

  • Basic Use of ApplyImpulse

    - by nycynik
    I am trying to apply a force to a bunch of b2_dynamicBodys, but it seems to only work for a random number of items and then stops with an error. //create some items to move bodyDef.type = b2Body.b2_dynamicBody; for(var i = 0; i < 5; ++i) { fixDef.shape = new b2PolygonShape; fixDef.shape.SetAsBox(1,1); fixDef.friction = 1; fixDef.restitution = .1; bodyDef.position.x = Math.random() * 10; bodyDef.position.y = Math.random() * 10; bodyDef.linearDamping=1; bodyDef.angularDamping=.8; itemsArray.push(world.CreateBody(bodyDef).CreateFixture(fixDef)); // store for later } then i try to apply a force later with: angle = 20; for (var xIdx=0; xIdx<itemArray.length; xIdx++) { itemsArray[xIdx].GetBody().ApplyImpulse(new b2Vec2(50*Math.cos(angle*Math.PI/180),50*Math.sin(angle*Math.PI/180));); } the error I receive is TypeError: 'undefined' is not an object (evaluating 'c.x') Is there something wrong with saving the items for later use when I am creating them? Does anyone know what is causing this.

  • What do you need to master a language and its technology? [closed]

    - by LongTTH
    Possible Duplicate: how to really master a programming language Let say about Java(just a sample, you can talk about C#, PHP, C++ ... it's just similar) and 10 (ten) levels, 1 is newbie and 10 is master. How can you identify someone at which level based on his knowledge? I do not tend to compare languages, I do tend to know what indicate a master or a newbie in a language and its (language's) based technology. Yeah, I know there aren't on earth a language stand alone, it always come with a technology with it. Let say in Java, you can memorize all of its keyword and syntax in just few days, but to know it (I mean do something with it effectively), you must read the Oracle (Sun) javadoc many many times (I'm not mention the 3rd party product yet).

  • java web development, what skills do I need?

    - by mrblah
    I want to learn, at least at a basic level, how to build java web applications (coming from a .net background). Meaning, I would like to be able to build, deploy a simple cms type application from the ground up. What exactly do I need to learn? Tomcat seems to be a good web server for Java. What options are there for the web? I know there is hibernate for an ORM. Does java have MVC? what about JSP? can MVC and JSP be together? beans? Maybe a book that covers all of these?

  • ASP.NET MVC - How do I implement validation when using Data Repositories? (Visual Basic)

    - by rockinthesixstring
    I've built a UserRepository interface to communicate with my LINQ to SQL Data layer, but I'm trying to figure out how to implement validation. Here is what my AddUser subroutine looks like Public Sub AddUser(ByVal about As String, ByVal birthdate As DateTime, ByVal openid As String, ByVal regionid As Integer, ByVal website As String) Implements IUserRepository.AddUser Dim user = New User user.About = about user.BirthDate = birthdate user.LastSeen = DateTime.Now user.MemberSince = DateTime.Now user.OpenID = openid user.RegionID = regionid user.UserName = String.Empty user.WebSite = website dc.Users.InsertOnSubmit(user) dc.SubmitChanges() End Sub And then my controller will simply call AddUser(...) But I haven't the foggiest idea on how to implement both client side and server side validation on this. (I think I would prefer to use jQuery AJAX and do all of the validation on the server, but I'm totally open to opinions)

  • Aggregating Excel cell contents that match a label [migrated]

    - by Josh
    I'm sure this isn't a terribly difficult thing, but it's not the type of question that easily lends itself to internet searches. I've been assigned a project for work involving a complex spreadsheet. I've done the usual =SUM and other basic Excel formulas, and I've got enough coding background that I'm able to at least fudge my way through VBA, but I'm not certain how to proceed with one part of the task. Simple version: On Sheet 1 I have a list of people (one on each row, person's name in column A), on sheet 2 I have a list of groups (one on each row, group name in column A). Each name in Sheet 1 has its own row, and I have a "Data Validation" dropdown menu where you choose the group each person belongs to. That dropdown is sourced from Sheet 2, where each group has a row. So essentially the data validation source for Sheet 1's "Group" column is just "=Sheet2!$a1:a100" or whatever. The problem is this: I want each group row in Sheet 2 to have a formula which results in a list of all the users which have been assigned to that group on Sheet 1. What I mean is something the equivalent of "select * from PeopleTab where GROUP = ThisGroup". The resulting cell would just stick the names together like "Bob Smith, Joe Jones, Sally Sanderson" I've been Googling for hours but I can't think of a way to phrase my search query to get the results I want. Here's an example of desired result (Dash-delimited. Can't find a way to make it look nice, table tags don't seem to work here): (Sheet 1) Bob Smith - Group 1 (selected from dropdown) Joe Jones - Group 2 (selected from dropdown) Sally Sanderson - Group 1 (selected from dropdown) (Sheet 2) Group 1 - Bob Smith, Sally Sanderson (result of formula) Group 2 - Joe Jones (result of formula) What formula (or even what function) do I use on that second column of sheet 2 to make a flat list out of the members of that group?

  • Software solution from the 2000's, should I attempt to patch or remake the whole thing?

    - by ShadowScripter
    I was sent out to discuss a system that a certain company is currently using and what should be done with it. The company manufactures various carton displays. This system was developed to keep track of clients, orders and prices. Lots have happened since the system was created and the system is now, as the manager described it, "locked up" and "problematic", which I translate as "not dynamic" and "unstable". Some info about the system It was developed around the year 2000 Fairly small system, 2-5 users, 6 forms, ~8 tables with average quantities of data Built on early Visual Basic, forms created with the drag and drop design. Interface is basically just a window with a menu and some forms Uses MSSQL database (SQL2005 server) to store data and ODBC driver to query, data was migrated from excel before this system, and before excel it was handled, calculated and written by hand and paper Users work in Microsoft XP environment (and up) Their main problem is that they can't adjust and calculate prices, can't add new carton types etc, correctly anymore because they can't (or rather, they don't know how to) touch the data on the server. I suggested 3 possible solutions Attempt to patch the current system Create a fresh new interface (preferably similar environment, VB.net or VB based) Bring it back to an Excel solution, considering it is such a small system There might be more options, but these are the ones I could think of. My questions are What should I recommend and why? What is or could be the pros and cons of these alternatives? Are there other (possibly better) alternatives?

  • Advice on improving programming skills, learning capabilities?

    - by anonymous-coward1234
    Hi all, After 2,5 years of professional Java programing, I still have problems that make my job difficult and, more importantly - more times that I would like to admit - not enjoyable. I would like to ask for advice by more experienced people on ways that would help me overcome them. These are the problems I have: I do not absorb new knowledge easily. Even when I understand something, after a couple of days I easily forget even basic stuff. Other co-workers, even with the same working experience, when reading new technologies put things easily into "context", and are able to compare in "real time| similar technologies they already have used. I always try to address all the issues to whatever I am doing at one go, which results in me trying to resolve too many problems at the same time, losing completely control. I find it difficult to make my mind on a single problem that I should address first, and even when I do, and find myself throwing away code that I wrote because I started addressing the wrong issue first. As far as architecture and data modeling is concerned, I have difficulty making decisions on what objects must be created, with what hierarchy, interfaces, abstraction etc. I imagine that - to a certain degree - these things come with experience. But after 2,5 years of Java programming, I would expect myself to have come much farther that I have come, both in terms of absorption and experience. Is there a way to improve my learning speed? Any books, methods, advice is welcome.
