• Connect android to database

  - by danny

  I am doing a school project where we need to create an android application which needs to connect to a database. the application needs to gain and store information for people's profiles on the database. But unfortunatly we are a little bit stuck at this point because there are numerous ways to link the application such as http request through apache or through the SOAP/REST protocol. But it's really hard to find good instructions or tutorials on the problem since I can't really find them. Maybe that's cause i'm probably using the wrong words on google. Unfortunately I have little relevant information. So if anyone can help me with finding relevant links to good online tutorials or howto's than those are very welcome.

• What are the other new features of C# 4.0, after dynamic and optional parameters?

  - by Abel

  So, C# 4.0 came out yesterday. It introduced the much-debated dynamic keyword, named and optional parameters. Smaller improvements were the implicit ref and recognizing of indexed and default properties on COM methods, contra- and co-variance (really a .NET CLR feature, not C# only) and... Is that really it? Are dynamic and optional/named params the only real improvements to C#? Or did I miss something? Not that I'm complaining, but it seems a bit meager after C# 2.0 (generics) and C# 3.0 (lambda, LINQ). Maybe the language just reached actual maturity?

• FMS: Stream.play on server side makes video choppy

  - by Tinelise

  I have an *.flv file on a FMS. When I play it on the client side the video plays just fine, but when I call Stream.play(filename, 0, -1, false) on the server side the video turns out really choppy. I both cases I use NetConnection to connect to an rtmp and NetStream to play the stream, but in one case I connect to a stream and request the server to play my file on that stream. Apparently that doesn't work with files? It works just fine for live streams. I really don't get why this should differ at all. Any suggestions?

• How to abandon a hg merge?

  - by Grumdrig

  I'm new to collaborating with Mercurial. My situation: Another programmer changed rev 1 of a file to replace 4-space indents with 2-space indent. (I.e. changed every line.) Call that rev 2, pushed to the remote repo. I've committed substantive changes rev 1 with various code changes in my local workspace. Call that rev 3. I've hg pulled and hg merged without a clear idea of what was going on. The conflicts are myriad and not really substantive. So I really wish I'd changed my local repo to 2-space indents before merging; then the merge will be trivial (i'm supposing). But I can't seem to back up. I think I need to hg update -r 3 but it says abort: outstanding uncommitted merges. How can I undo the merge, changes spacing in my local repo, and remerge?

• Why is there no Microsoft Certified Master program targetted at developers?

  - by Jason Coyne

  In the lower level certifications, developer technology is all over the place. At the highest level (Microsoft Certified Architect), the Solutions track appears to be a good fit for high level application designers and architects. MCA requires an MCM as a prerequisite. However, none of the MCM tracks are targeted towards development. Obviously to be a good architect you need to have knowledge of other technologies, servers, sql, messaging etc. But those seem like things that should be part of the course load, and not the sole focus. Are the lower tiers really as high as you can go for application focused professionals? For most developers, the SQL MCM seems to be the best fit. Are the MCM and MCA really targeted ad more administrators and not developers?

• Fastest way to store/retrieve a dictionary - SQL, text file...?

  - by AP257

  Hi all, This is a really really super dumb question, so I apologise, but I'd be grateful for some advice. I've got a text file of words and word frequencies. It's very large - theoretically we're talking millions of rows. I just want to retrieve values from the file, and do it as quickly and efficiently as possible (for a web app, in Django). My question is: what is the best way to store and retrieve the values? Should import them into SQL? Or keep the file and use grep? Or put them into a JSON dictionary...? Or some other way? Sorry for the dumb question, would be very grateful for advice!

• Error: Get JSON Data from Web API Using Jquery

  - by Kenneth

  I'm really new at this. And I'm really stuck. I have the jquery code, it will load data from Web API, but it does not display on my page. $.getJSON("/api/Order", function(data) { if (data != null) { var str = ''; $.each(data, function (item) { str = '<li>' + item.ItemName + '</li>'; }); $("#contents").append(str); } }); Can anyone explain what is going on? Thanks.

• BCB: how to get the (approximate) width of a character in a given TFont?

  - by mawg

  It's a TMemo, not that that should make any difference. Googling suggests that I can use Canvas->TextWidth() but those are Delphi examples and BCB doesn't seem to offer this property. I really want something analogous to memo->Font->Height for width. I realize that not all fonts are fixed width, so a good estimate will do. All that I need is to take the width of a TMemo in pixels and make a reasonable guess at how many characters of the current font it will hold. Of course, if I really want to be lazy, I can just google for the average height/width ratio, since height is known. Remember, an approximation is good enough for me if it is tricky to get exact. http://www.plainlanguagenetwork.org/type/utbo211.htm says, " A width to height ratio of 3:5 (0.6) is recommended for most applications"

• How not to lose focus on a login page

  - by Misha Moroshko

  I have a simple login form with 2 input fields: "username" and "password". "username" field is focused by default. The problem is that when user clicks outside "username" or "password" fields, the focus is gone (it is neither on "username" nor on "password" fields"). How can I force the focus to be on these 2 fields only ? In my case, this is a really annoying behavior, so I really want to do this :) Can I do something like: $("*").focus(function() { if (!$(this).hasClass("my_inputs_class")) { // How to stop the focusing process here ? } }); ?

• Object pointer value as key into dictionary

  - by Ranking Stackingblocks

  I want to use the object's reference value as a key into a dictionary, as opposed to a copy of value of the object. So, I essentially want to store an object associated with a particular instance of another object in a dictionary and retrieve that value later. Is this possible? Is it completely against the idea of NSDictionary? I can tell that I am probably approaching this the wrong way because the dictionary wants me to implement NSCopying on the object itself, which doesn't really make sense in terms of what I'm doing. I can see that what I should really be doing is wrapping the pointer value, but that seems a little mad. Advice would be appreciated.

• Package names - impl v internal

  - by Ben J

  In my time of digging around Java APIs I have come across both impl and internal packages. Up until now I never really thought about the difference - as with all enterprisey Java apps, I figured they just meant that "actual implementation in here; you (API user) should be really using the interface. Go away." A little bit of digging around Stack Overflow seems to suggest that the internal package at least can have some security placed around it. So, what is the difference? I don't think it is a matter of taste because I have seen APIs with both.

• Best Practices for Working with Multiple Monitors in Visual Studio 2010

  - by Clever Human

  Now that Visual Studio 2010 has support for multiple monitors, I am curious how other people have their environments arranged. I have yet to come up with an arrangement that I am really satisfied with. The current best I have come up with for my 2 monitor system is to have all code windows detached. Then, on my primary monitor, I am able to have two code windows side by side (using the Windows 7 keyboard shortcuts WinKey+LeftArrow and WinKey+RightArrow.) On my secondary monitor I put the rest of the IDE with all of the tool windows that are normally on the bottom (errors list, find window, call stack, etc...) docked where the code windows normally go. I've also tried having all those things detached and having almost nothing in the IDE proper. The problems with this layout are: Newly opened code windows always open in the IDE, not on top of one of the detached windows. Detached code windows do not remember their exact placement from session to session (they are slightly off, having me to use the winkey + arrow key shortcut again and again for each window. There seems to be no way to have the code panes aware that they are on top of one another (IE -- multiple tabs.) The CTRL+TAB shortcut always displays on top of the IDE proper. The Code Panes are always "on top" of (children of) the IDE. So clicking on any code pane brings the IDE to the foreground, even when I care only about that code pane, and not the IDE. Other more minor issues... What would go a long way to making this better is having the code panes detach such that they are tab strips that can have other code panes docked within them. The new multi-monitor support in VS2010 is good, but it still seems really lacking. Can these issues be solved with an add-in? If so, is anyone aware of one? Is there a better way to work with the IDE on multiple monitors than what I am doing? NOTE: While this question is subjective (there is certainly no "this is the best way and that's final" answer) I'd really like to know possibly better methods of working with the IDE than what I have come up with. The intent is not to start a "mine's best" flame war.

• Asking browsers to cache as aggressively as possible

  - by balpha

  This is about a web app that serves images. Since the same request will always return the same image, I want the accessing browsers to cache the images as aggressively as possible. I pretty much want to tell the browser Here's your image. Go ahead and keep it; it's really not going to change for the next couple of days. No need to come back. Really. I promise. I do, so far, set Cache-Control: public, max-age=86400 Last-Modified: (some time ago) Expires: (two days from now) and of course return a 304 not modified if the request has the appropriate If-Modified-Since header. Is there anything else I can do (or anything I should do differently) to get my message across to the browsers? The app is hosted on the Google App Engine, in case that matters.

• What should I tell kids about how great it is to be a programmer?

  - by Sara Chipps

  I am putting a presentation together. I thought about illustrating with websites like Facebook, and MySpace. Does anyone have children around that age that could tell me what they are into? How to hold their attention? Ways to illustrate what we do? Get them interested? Your ideas are greatly appreciated, I really want to be able to convey how fun this is :). I don't have access to a digital projector... which really stinks. I do have access to an old transparency overhead, though. http://stackoverflow.com/questions/207278/career-day-how-do-i-make-computer-programmer-sound-cool-to-8-year-olds

• TypeError: Error #1009 Actionscript 3 help.

  - by matt_t

  I am extremely frustrated. I'm following a tutorial and mimicing it on my own. I've been able to sort out most of the errors so far but this one has me stumped. I have tried replacing all of the class files with the tutorial specimen ones but i still get the error. TypeError: Error #1009: Cannot access a property or method of a null object reference. at com.senocular.utils::KeyObject/construct() at com.senocular.utils::KeyObject() at com.asgamer.basics1::Ship() at com.asgamer.basics1::Engine() Now, not really understanding the error properly I paste dumped the files online for you to look at. Ship class: textbin.com/78z35 Engine class: textbin.com/32b24 KeyObject class: textbin.com/p2725 As the error still occured when using the specimen class files I really have no idea where to begin. I will gladly try out any suggestions (although later on, i'm tired now ;). Thanks very much.

• VBScript - using IF statements in a mail script?

  - by Kenny Bones

  I really need some quick tips here. I've got this VBScript script which sends an e-mail. And I want to do several checks to see if an attribute is true and if it is, write an additional line in the mail. How can I do this? This is part of the script: obMessage.HTMLBody = ""_ & "<MENU>"_ & "<LI type = square>This is a line</i>."_ I want something which looks like this: obMessage.HTMLBody = ""_ & "<MENU>"_ If statement1 = true Then & "<LI type = square>This is an additional line</i>."_ end if Preferrably, could some select statements be made? I don't really mind what the code looks like, I just want it to work as soon as possible :)

• DrawRect on the iPhone vs. the Mac

  - by Joe Cannatti

  I am an experienced iPhone dev beginning to work on my first Mac app. One thing that is really throwing me off is the differences between UIView and NSView. It seems that I cannot set the background color of a NSView via interface builder as I can with a UIView. It also seems that I cannot do it by simply sending a setBackgroundColor: message to it. All the examples I have seen are overriding drawRect: in a subclass of NSView. Is that really the only way to do it? What is the conceptual difference here, and why is it this way? NOTE: I am only trying to set the background color to the default grey.

• Cheap Wifi enabled Android or other programmable device

  - by Darran

  Does anyone know of a cheap Android or programmable device that has wifi? I need it for a project for a company that needs a wifi handheld device for the shop floor. Im not too fussed about the language the device uses though Im not really interested in the iTouch as theres no intention to release the app in the app store and I don`t really want to jail break everybodys iTouch. Ideally it would be small , iTouch size for example and relatively cheap $100 or less. Nothing fancy just ability to write a simple UI and have wifi. Voice is not needed. Not too fussed about touch or qwerty keyboard either.

• What are the differences between MVP, Presentation Model, MVVM and MVC?

  - by Nicholas

  I have a pretty good idea how each of these patterns work some of the minor differences between them, but are they really all that different from each other? It seems to me that the Presenter, Presentation Model, ViewModel and Controller are essentially the same concept. Why couldn't I classify all of these concepts as controllers? I feel like it might simplify the entire idea a great deal. Can anyone give a clear description of their differences? I want to clarify that I do understand how the patterns work, and have implemented most of them in one technology or another. What I am really looking for is someone's experience with one of these patterns, and why they would not consider their ViewModel a controller for instance.

• Why use constants in programming?

  - by Adam N

  I've just been going back over a bit of C studying using Ivor Horton's Beginning C book. I got to the bit about declaring constants which seems to get mixed up with variables in the same sentence. Just to clarify, what is the difference in specifying constants and variables in C, and really, when do you need to use a constant instead of a variable? I know folks say to use a constant when the information doesn't change during program execution but I can't really think of a time when a variable couldn't be used instead. Thanks

• How should I build a simple database package for my python application?

  - by Carson Myers

  I'm building a database library for my application using sqlite3 as the base. I want to structure it like so: db/ __init__.py users.py blah.py etc.py So I would do this in Python: import db db.users.create('username', 'password') I'm suffering analysis paralysis (oh no!) about how to handle the database connection. I don't really want to use classes in these modules, it doesn't really seem appropriate to be able to create a bunch of "users" objects that can all manipulate the same database in the same ways -- so inheriting a connection is a no-go. Should I have one global connection to the database that all the modules use, and then put this in each module: #users.py from db_stuff import connection Or should I create a new connection for each module and keep that alive? Or should I create a new connection for every transaction? How are these database connections supposed to be used? The same goes for cursor objects: Do I create a new cursor for each transaction? Create just one for each database connection?

• How do I do import hooks in IronPython/Silverlight?

  - by ahlatimer

  I'm extending TryPython to (along with various other things) allow users to save a file and subsequently import that file. TryPython overloads the built in file operations, so I need to know what parts of import need to hooked into in order for import to use the overloaded file operations. Really, a basic overview of IronPython's import when used in Silverlight would be extremely helpful. I don't need a complete working solution (although I won't stop you from writing one! :). I'm a Python newbie, and I really have no idea where to even begin. Thanks!
