• Is it good practice to separate code into blocks?

  - by LM

  If I have a method that does multiple, related things, is it good practice to stick each "thing" that the method does into a seperate block? Ex. { int var //Code } { int var //More Code } It would help reduce the number of local variables, and make the code more readable, but I'm not sure if it's a good idea.

• Where to find Python CouchDB tutorials?

  - by Cap

  I've been hunting around for a Python CouchDB tutorial and haven't been able to find anything very thorough. The only thing I've really found is this site, which I haven't gotten to work because I keep getting a 'connection refused' error when I try to create a database. Does anyone know where I would look for a tutorial to help me with this?

• Storing a type in C++

  - by perimosocordiae

  Is it possible to store a type name as a C++ variable? For example, like this: type my_type = int; // or string, or Foo, or any other type void* data = ...; my_type* a = (my_type*) data; I know that 99.9% of the time there's a better way to do what you want without resorting to casting void pointers, but I'm curious if C++ allows this sort of thing.

• <object> pasted into textarea is removed... why?

  - by swt83

  I have a textarea that saves data into a database. For some reason it is removing <object> tags from anything that I paste into it -- none of the other tags are removed, only <object> tags. I've never had this problem before and have done this same thing in times past -- any ideas as to what could cause this? I'm not filtering the data before it's saved to the db at all.

  What I'd like is for this class class Car { public function __construct(Engine $engine, Make $make, Model $model) { // stuff } } Get an array that has the types needed to construct this car (Engine, Make, Model) in the order they are needed for the constructor. I'm using this for a Dependency Injection-esque thing I'm making.

• Build MSI to install DLL and make it accessible from "Add References" in VS

  - by Jon Harrop

  I'd like to build an MSI installer that installs a managed DLL and makes it accessible to users from Visual Studio's "Add References" menu in Solution Explorer. I believe I am supposed to add a key into the Windows registry but I cannot see how to tell the VS project for the MSI to do this at install. How is this done and where should I look for tutorials on this kind of thing?

• Is it possible to make this Flex/Flash application safe?

  - by Frank

  I'm back with another Flex/Flash security question. I've already received some help from the community on this topic, but I'm still not quite sure this is the best way to do. Here's the thing. A flex web app, a lot of users (1000+), custom configuration of the application depending of the user group. Can I make this thing safe... or safer. For the moment, when a user comes to the application, there is only one configuration possible, but for the next version we've implented a multi-configuration protocol, this way : 1. The user connect to Default.aspx, server code process the windows credentials (whe are on intranet) and give the correct xml configuration file. 2. The flex app loads with the xml conf file as a flashvar and then the app 'builds' itself with the content of the xml file. As we know, since this is a flex application the swf is downloaded on the client computer and the xml file too. If more than one user connects to the app, from the same computer, the can possibly see the other xml file in the windows temp folder. The current directory of the application looks that way : Web site |-> default.aspx |-> index.swf |-> configAdmin.xml |-> configUserType1.xml |-> configUserType2.xml |-> com |-> a lot of swf and xml files I was first thinking making another directory (without read access for the client) containing all the configurations xml files, picking the right one, copying it to the client and deleting it afterwards. But it seems like I must let know the user know when downloading/deleting content on it's computer... I'm running out of ideas, so I hope you have some great ones. It's there are some design flaws (in the way the app is build, not in Flash :p) please share. I'm always looking forward to improve. Thanks Update : In browser Flash/Flex (without AIR that is) doesn't allow deleting file localy silently (on the client computer, where the application is). It's also not yet possible to get session data.

• Regular expression - starting and ending with a letter, accepting only letters, numbers and _

  - by jreid9001

  I'm trying to write a regular expression which specifies that text should start with a letter, every character should be a letter, number or underscore, there should not be 2 underscores in a row and it should end with a letter or number. At the moment, the only thing I have is ^[a-zA-Z]\w[a-zA-Z1-9_] but this doesn't seem to work properly since it only ever matches 3 characters, and allows repeated underscores. I also don't know how to specify requirements for the last character.

• What's the difference between PlaceHolder and <div />?

  - by DaveDev

  In an ASP.NET project I have the following HTML: <asp:PlaceHolder ID="plcTitle" runat="server"></asp:PlaceHolder> <div id="divStrapline" runat="server" /> which are populated with this code: if (this.TitlePanel != null) { plcTitle.Controls.Add(this.TitlePanel); } if (this.Strapline != null) { divStrapline.Controls.Add(this.Strapline); } Are they both the same thing? Is either better than the other? Why?

• Port AS3/Flex app to iPhone

  - by John

  I believe Adobe tools like CS5 have ways to output as an iPhone app, but what about a regular AS3 or Flex project? Are there any tools to auto-port, or AS3/Flex iPhone implementations out there? Out of interest, how does the CS5 thing work? Is it a totally different code-path or something less drastic? For instance Flash supports Shapes and Timelines, etc... do they in fact provide an iPhone Flash runtime of some sort?

• Ext JS - Can I 'chain' methods on a field ??

  - by dwfresh

  HI, I am just trying to set a field value and disable it at the same time. Can this be done in ext js? The docs are very weak on this subject. something like this generates errors: myForm.getForm().findField('start_date').setValue('').setDisabled(true); I'm used to JQuery which does this sort of thing nicely but haven't had luck with Ext. Thanks for any help.

  I've got an app that's approved by Apple and ready-for-sale, but we're holding off for a few days for press reasons.

Does it matter that it's approved, can I just give select users a file without the provisional stuff?

• Facebook data collection ethical issues

  - by the_great_monkey

  If I have a Facebook app, and my users agree to allow my app to access their information, photos, friends, etc, is it ethical to grab their information when they log in, and then saving it in memory so that the next time he goes to my app, it can load faster? If so, what about when the user logged off? Is the right thing to do to is to delete all the cached information and photos that the user provided? Has Facebook got any way to detect that we're doing this (saving their information, etc)?

• returning aligned memory with new?

  - by Steve

  I currently allocate my memory for arrays using the MS specific mm_malloc. I align the memory, as I'm doing some heavy duty math and the vectorization takes advantage of the alignment. I was wondering if anyone knows how to overload the new operator to do the same thing, as I feel dirty malloc'ing everywhere (and would eventually like to also compile on Linux)? Thanks for any help

• #region in XAML

  I actually don't like #region in my code. BUT for some reason call me crazy, I would like to have them in my XAML.
