• [Android] How do I load URL that requires login into variable?

  - by bebeTech

  I am trying to port my usage meter from a JavaScript Gadget (win) / Widget (OSX) to Android. Total newbie when comes to JAVA + Eclipse + Android 2.1 SDK. Essentially what I want to do is load a page, pass through a username and password and load the resulting page into a array that I can then run some regular expressions through. My code from JavaScript (I've replace the actual URL with a dummy one) is: xmlhttp.open("post","https://acme.com.au/your_account/index.php?function=login",false); xmlhttp.setRequestHeader("If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT"); xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); xmlhttp.send("check_username=" + username + "&password=" + password); I need to know the Android equivalent to the above please. I've played around with WebView but that loads the page in a web browser which isn't what I want.

• Another Nim's Game Variant

  - by Terry Smith

  Given N binary sequence Example : given one sequence 101001 means player 0 can only choose a position with 0 element and cut the sequence from that position {1,101,1010} player 1 can only choose a position with 1 element ans cut the sequence from that position {null,10,101000} now player 0 and player 1 take turn cutting the sequence, on each turn they can cut any one non-null sequence, if a player k can't make a move because there's no more k element on any sequence, he lose. Assume both player play optimally, who will win ? I tried to solve this problem with grundy but i'm unable to reduce the sequence to a grundy number because it both player don't have the same option to move. Can anyone give me a hint to solve this problem ?

• Java 7 API design best practice - return Array or return Collection

  - by Shengjie

  I know this question has be asked before generic comes out. Array does win out a bit given Array enforces the return type, it's more type-safe. But now, with latest JDK 7, every time when I design this type of APIs: public String[] getElements(String type) vs public List<String> getElements(String type) I am always struggling to think of some good reasons to return A Collection over An Array or another way around. What's the best practice when it comes to the case of choosing String[] or List as the API's return type? Or it's courses for horses. I don't have a special case in my mind, I am more looking for a generic pros/cons comparison.

• MVP pattern. Presenter requires new view instance. Best practice

  - by Andrew Florko

  I try to apply MVP pattern for win.forms application. I have 2 forms: main & child. Main has a button and when you click it - child form should appear. There are 2 views interfaces that forms implement IMainView { event OnClick; ... } IChildView { ... } There are two presenters MainPresenter(IMainView) & ChildPresenter(IChildView) MainPresenter listens to OnClick event and then should create IChildView implementation. MainPresenter { ... MainClicked() { // it's required to create IChildView instance here } } How would you implement such creation typically? Shall IMainView has factory method for IChildView or may be it should be separate Views factory. What would you advise? Or maybe there is some misunderstanding of MVP here? Thank you in advance!

• What's Your favorite f# use? where does f# makes life (a lot) easier (compared to c#)?

  - by luckyluke

  I've skimmed the stack and did not get the overflow as there is probably no such question. I'm just learning f# and I am A seasoned c# and .net dev. I am into financial apps and currently F# helps me a lot with maths calcs like zero finding or minimum finding (although I still want some good maths library there). I see that processing multiple items (files or smth) tends to be easier, but my GUI (web, win) are still c# based. I am in the team of 5 devs and we know that the new tool is out, we are learning it after hours (to pimp ourselves up) but maybe we shouldn't bash the door somebody already opened. So in business apps, whats Your first killer part of soft You would code in F# (if You could and would know IT would be easier, faster, more testable, easier to maintain etc.? Business rules? ImageProcessing? Data processing? hope it's not to subjective. luke

• Pass information to php file from javascript while restricting user from doing it their self?

  - by Sean Madigan

  I am making a game where the battle system uses javascript to battle. At the end of the battle you either win or lose. If the user wins, I need to update the mysql database with the XP they earned. The best way I can think of doing this is to have the javascript run an ajax function when the user wins that POSTs something like addxp.php?amount=235, but if I do that then the user can easilly look at the source and see that they can just enter in that page themself to update their xp without battling. But this is the only way I know how to do it? Help please :-/

• Why TortoiseHg not show the "merge conflict"?

  - by Jian Lin

  Short version of the question: Since I already have TortoiseHg, I right clicked on that file trying to see the merge conflict visually, but there is no way to see it? Details: To make a simple case of merge conflict, I hg init a repo on Win 7, and then clone it to another folder. Now, in one working directory, i added the line "the code is 123", committed. And in the other folder, i did an "hg pull" and "hg update" Now, I go back to the first folder, and change "123" to "123abc", and then do an "hg commit" And then I go to the other folder and edit "123" to "123xyz" over there, and do an "hg commit", and when "hg push", it says it can't. So I try to use any visual tool to see how the conflict is like, but ... TortoiseHg doesn't seem to have any option to do that?

• Using ASP.Net 4.0 for new Dev projects

  - by JBeckton

  I am currently in the early stages of developing a couple web applications, I have not written any code yet as I am still just gathering requirements and scoping things out. I want to target ASP.Net 4.0 winforms as the platform for these apps but I want to make sure there are no glaring issues with this new version before I commit. I understand that if I was porting an existing app from 2.0, 3.5 to 4.0 there may be issues but I am starting from scratch on these projects and plan to write these apps to support the new features of 4.0. Should I wait for the first service pack to come out? Just seems like more work to start with 3.5 now only to go back through and tweak things for 4.0 in just a few months or even before I finish the app. Our servers are Win 2K3 with IIS6 and MS SQL 2000, Should I expect any problems with VS 2010 and MS SQL 2000 in regards to Linq to SQL and EF?

• Write-access for c# app in it's own exe dir in Windows 7

  - by fritz

  I know that user accounts in Windows 7 are limited by default, so a program cannot just write anywhere on the system (as it was possible in Win XP). But I thought that it would be possible that e.g. a c# app is allowed to write inside it's own exe-directory or it's subfolders at least (not everything is 'user settings' or should be written to "MyDocuments"...). So currently my c# app throws an UnauthorizedAccessException when trying to write inside the exe dir. Is there anything you can do in c# code to allow writing inside the exe dir?

• How to create a changelog?

  - by Jasper Kennis

  I'm building a site that shows changes in deals that we have in our db. For example, if a deals status changes from pending to win, I want to show it, and if the value goes up or down, I want to show it, that kind of thing. Also, if you open the overview page, I want it to show the history of changes. So I need some kind of change logging, to be able to look in the past. How do I do this? It is a rails project, but I think that's irrelevant.

• Managed HttpListener vs C++ Network Lib - Requires admin rights?

  - by Max

  So, I have noticed that starting an HttpListener is considered impolite according to Win 7. I cannot do so without administrative rights without adding myself to some URL reservation list. In theory, this is alright, but I'd like to make my program as little invasive as possible. My main other alternative is something like the c++ Network Library, which utilizes boost. This is probably not as simple as a HttpListener though. Will this circumvent the admin rights requirement for listening to some HTTP url? How does windows handle http listening? Right now I'm just listening to http://+:xxxx/url, I guess it's fully possible to just create a Socket listening at port xxxx and provide my own/third party http implementation?

• Browser App - RAD UI Development - Is it possible?

  - by Randy Minder

  I've been away from building browser applications for a long time. I'm now interested in creating one for a hobby of mine. I dread having to deal with HTML, JavaScript etc. to build a high quality browser based user interface. I've got the full suite of Telerik controls. Is it possible to build a polished, somewhat feature rich browser UI while being sheltered from the archaic environment of HTML and JavaScript? I'd love to be able to simply drag-drop components, much like building a Win UI and have the exact HTML, JavaScript code created for me. Thanks!

• Get list of running processes, get active process (and it's application) Flex/AIR

  - by Adam Kiss

  Hello, just a quickie (or maybe not:] ): Is it possible to get somehow list of running applications/processes and, while running in background, check which process is active? Additionally - if somehow, the answer was yes, is it possible to react for change of active window / application react just as if it was Event, or bind to it custom event (e.g. Event.SystemActiveAppChange)? Thank you for answers as well as pointers. EDIT: Due to probable missunderstanding, I mean local applications - on your win/mac/linux machine - I would like to (in process of learning of language) track what apps I use the most, make a little graph maybe? So, the point is: in AIR app, developed in FLEX, I would like to get/list all running applications/processes, as well as which one is active (on user's PC/Mac/Linux)

• GIT vs. Perforce- Two VCS will enter... one will leave.

  - by Justin Bozonier

  So I'm in the process of getting GIT sold at work. First thing I need is to convince everyone that GIT is better at what they're already used to doing. We currently use Perforce. Anybody else go through a similar sale? Any good links/advice? One of the big wins is that we can worth with it disconnected from the network. Another win imo is the way adds/checkouts are handled. More points are welcome! Also we have about 10-20 devs total.
