I think Java2D is pretty easy to work with, but if you don't already know Java there's a fair amount of stuff you need to do up-front. Here's a basic Java application that opens a window and provides a Graphics object, the basis of all Java2D drawing:code:

That seems simple enough, and Java is one of the two modern languages I know (the other being Python). I'll give it a shot!

I would say it a little easier to use and a little more intuitive than Swing, but the documentation isn't too good; Java definitely has the advantage in that department.

I am lucky enough to have work pay for some java training for me. I used to program, but have not done any real coding in at least 5 years. I have narrowed it down to 3 courses that seem to fit what I need, but I don't know which one, if it matters, would be best. Have any of you taken classes or courses with any of these places, and if so do you have a recommendation? Does it not really matter in the scheme of things?

Just so much easier and nicer for me to learn at than a virtual class.

I don't know C++ or Windows programming at all, so...could anyone tell me why the compiled version of this source isn't printing its output to stdout? It outputs to the console just fine, but if I try to redirect it from the command line like "compiled.exe > test.txt" I get a blank file...same results if I try to capture stdout by calling it from Python's subprocess or popen. I see it's using wprintf to output, but from my meager Googlin' that's supposed to write to stdout...

Misogynist posted:The best way to code is to just, well, code. I think that classes like these, where they teach you nothing of value and just dick around with Swing and JDBC, are an awful way to spend money. Because they are paid for, structured, and are in a time block that will force me to work on learning to code in Java. My main purpose at work and my personal life is not coding, its a secondary if not tertiary aspect of my job and now we have grant funding to pay for it. I don't particularly want to spend my free time teaching myself to code, nor do I want to assume that I will teach myself to do it in the same time when I have other work I could be doing instead. If I was paying for this myself and I was in my early 20s I would totally agree with you, but right now life doesn't seem to work that way for me and the opportunity is here. Bottom line is I have a fixed amount of money that must be spent on programming training, specifically java. If there are better structured classes or methods out there that's fine, but go and buy a couple a books and teach yourself isn't an option. Not so much because I can't do it, but because I know won't do it if it goes that way (and the money can't be spent that way, federal grants are very strict).

No, I want to learn, but I also know what does and does not work for me, and I have limits on how and when the funds can be spent. Just because buying a couple books and sitting in a coffee shop for a week working through them works for some of you does not mean it works for me or that it is even an option I can consider. If you have a suggestion for a structured learning method with instruction that costs around $2500 I am all ears. If you think all 3 of those places are crap, that's equally valid. If you have experience that one is better than the other I would like to hear it. I do have to ask, have you attended the ~5 day bootcamp type courses before or only believe they are terrible? Its also not like I haven't coded before. I did get my undergraduate education in computer science in the late 90s and did programming work for a few years after wards. Coding just has not been a big part of my responsibilities lately and they are not going to become a major part of them anytime in the near future.

There's a very common sentiment among programmers that all (or nearly all) such "structured learning methods" are a waste of time. So I'm not surprised to see you get little help here. (And I think saying "it needs to cost $2500" is putting people off--maybe just say your grant is for $2500. Surely you'd accept a workable solution that cost $10?) You say you got your undergrad in CS. Did the classes that involved programming work for you? If they did, or you think they would, why not take your grant and enrol in a course for a semester at a local college? Call up an advisor or someone and explain your situation, see if they have a course that might work for you. $2500 might get you close enough for tuition for one course, and you can stretch your week off into a few hours off a week to attend lectures.

Yes, that is certainly true that I am open to other less expensive suggestions as well. I am sorry if I came off as abrasive, but it was a little frustrating to ask about the quality of trainers and then be presented with the idea that your wasting your time and the only way to learn to program is to teach yourself. The courses in my program did teach me and I liked how they went. Its just that not only have I not written code in quite a while, but I learned in Object pascal and last wrote things in C++. I, too, furthered my own education after school and work by coding for fun and just trying new things, but I have an opportunity right now to have something structured paid for to get me back into it so I can hopefully do some support and possibly even plugins for our open source platforms. I did look into local schools and, unfortunately, they are not going to work. The community collage would have been an option but they don't have an applicable course available this coming semester. The other area colleges won't accept me without enrolling as a student and into the program, and they didn't want an auditor for a course like this. As far as I can tell, and I very well could be wrong, but these boot camp type courses are all that are available that fit the stipulations of the grant.

They buzz through a book and some examples, skip a ton of stuff, and you don't really learn much. Why? There's just not enough time to actually explain things, ask questions, and learn from each other. Now, they can be a good way to get started with a new technology. But if you look at the amount of things they plan on covering in the class, you'll see there's no way they can spend any more than 10 or 15 minutes on each thing. You could literally spend 3 days going over just classes in Java, along with the application/examples of them. Usually, the classes are full of fucktards who are forced to go their by their jobs. And most of them just play around on the internet all day. Those schools are in it for the money and know corporations will pay. But it's like companies don't care (or don't know) that they are literally gaining nothing by sending their employees to poo poo like this. You just can't learn programming in 5 days. Second, do you personally want to learn Java or is your employer making that decision for you? Unless you have a personal project you want to do in Java (Android stuff for instance) I would run like hell and take a class on C# or Ruby or PHP or anything else.

I would like to get back into coding a bit, but I have so much stuff on my plate right now professionally and personally that I can't be too choosy. Java fits work needs, as we have 3 open source platforms that are all based on java, and I can make it fit for most things I might want to do personally. I was a little worried these types of classes might be like that. I'll probably just have to make the best of it. If nothing else I am hoping that it also makes me more eager to work on coding more. Even if the class itself isn't the best that doesn't mean it can't be an inspiration to start messing around more on your own with at least some sort of grounding to start from.

Just to run it into the ground, let me just link the classic Teach Yourself Programming in Ten Years essay. If you do decide to take one of those courses, I would suggest to bring one of your own projects and work on it when the teacher is just rambling, then take any chances to ask the teacher for advice on any problems you face with your own project.

I am not expecting to be a java expert after one of these courses, but to at least have a better standing afterwards than I do with my current coding foundation. The class is indeed free for me, so if there is no discernible difference between the organization teaching them I guess I will just go with whoever fits my schedule best and make the most of it.

Quick question here, but is it possible to stop an application from stealing global hotkeys on Windows? I've got a game (not fullscreen) that eats my foobar global hotkeys. They aren't media keys but rather Alt + numpad keys (I don't care about using them for special characters). Autohotkey is strangely unaffected, so I've got an Autohotkey script that will temporarily change focus from the game when I press these keys. This is still not the best as the double-focus switch is far from instantaneous. Any better solutions? I've tried using Autohotkey's SendControl function but it isn't working with foobar. Edit: Basically, what's the best way to capture and redirect the keystrokes to foobar without using Autohotkey's SendControl function or changing window focus. I'm happy to use a proper language to make this if it's going to work, I'm just not sure where to look. Met48 fucked around with this message at 21:58 on Jul 28, 2011 |

The regex is a straightforward translation of your description. [any upper character or digit 0-9] = [A-Z0-9] [dash] = - So the regex is [A-Z0-9]-[A-Z0-9] As for the actual problem - given a string and a regex, return a list of all substrings matching that regex - there's bound to be something in PHP's string library that does that, right? (I don't know PHP.) Quarantini posted:edit: I tried ([A-Za-z0-9-]+) with some online regex maker but it only seems to match the 1st valid needle in a haystack and not any of the others, i want to be able to feed the expression a bunch of data containing the above strings and be able to have it returned into a cleaned array The problem with that is not the regex (although it is wrong) but presumably the fact that you're searching using a function that returns the first match rather than all matches.

You can of course wrap it into something simpler. You know, one thing you could do was override the table lookup metamethod for your objects, such that looking up one of the functions in the class using the regular . operator yields a function bound to the object. code:

Of course, this means that while foo.Test(3) will work, and DoSomethingFourTimes(foo.Test) will work, foo:Test(3) will not (which can be an interesting surprise violation for other Lua coders looking at your program). I'm pretty sure that there's an unofficial patch on the lua-users wiki that makes foo:bar syntactic sugar for function(...) return foo:bar(...) end, which you could use if you don't mind breaking compatibility with "stock" lua. Alternately, you can wrap it in something more explicit: code:

I asked this in the 'Random Questions' megathread in Ask/Tell but did not receive a response. Maybe this is a better place? I'm trying to properly categorize an application for my resume. This application allows users to log on and send subject data to our company via an internet browser per FDA rules. The user can give us details about the transfer, see past transfers, write on a message board, read and answer queries, ask questions, and download information regarding their specific trials. This application runs on a server at our data center in NJ. The client needs to download an ActiveX plug-in and that's it. Is this SaaS CRM? SaaS CMS? Just SaaS? Just CRM? Just CMS? ASP? None of the above? I don't know! At present I'm calling it a content management system/data transfer application. However that strikes me as wrong, misleading, outside of the industry nomenclature, and unprofessional. So yes, please let me know how best to describe this application. Thanks in advance.

Keep a master resume full of everything you've ever done, then make a copy and cut that down so it fits whatever job you're applying for to a tee. Keep the master resume up to date, try to add new stuff to it at least once a year so you don't forget all the kickass projects you can mention having worked on. This also helps when negotiating a raise, as you'll be able to point to stuff that added value or whatever.

I am attempting to resolve an error message in a set of php code and I am struggling to determine why. Note: I am not a very experienced programmer (to say the least) and I was given this code by our programming team to adapt and modify for use in our department. I have been able to resolve every error and issue up until this point, but now I am struggling. The page itself is a listing of different values for a given trainee, each of which is selectable in a form which can be submitted to updated the given information in the database. I am consistently getting the error message quote:Warning: Invalid argument supplied for foreach() in /home/kaplanho/public_html/Testing/KTDP/ktdp/scheduling/admin/headers.php on line 45 I am assuming this is because the argument in that foreach() loop is either null or not an array, but I cannot figure out why that is true. The posted changes do get saved, but I cannot figure out how to get rid of that error message. Here is the code in question. First, a portion of the revelant trainee.php page code: code:code:I don't understand how the argument could be null or not an array given the check that's used the line before the offending line to ensure the contents of the posted field. Any and all help is hugely appreciated!!!
