Convert enums to human readable values
Does anyone know how to transform a enum value to a human readable value? For example: ThisIsValueA should be "This is Value A".
Converting this from a vb code snippet that a certain Ian Horwill left at a blog post long ago... i've since used this in production successfully. /// /// Add spaces to separate the capitalized words in the string, /// i.e. insert a space before each uppercase letter that is /// either preceded by a lowercase letter or...

GUI system development resources?
Could someone recommend any good resources for creating Graphics User Interfaces, preferably in C/C++? Currently my biggest influence is 3DBuzz.com 's C++/OpenGL VTMs (Video Training Modules).

I wouldn't use OpenGL for the GUI unless you are planning for hardware accelerated and/or 3D effects that you don't think you would get with a more traditional GUI toolkit (e.g Qt, wxWidgets, GTK, etc). If you just need a quick simple GUI for hosting your OpenGL graphics then FLTK is a nice choice. Otherwise, for rende...

Validate Enum Values
I need to validate an integer to know if is a valid enum value. What is the best way to do this in C#?
You got to love these folk who assume that data not only always comes from a UI, but a UI within your control! IsDefined is fine for most scenarios, you could start with: public static bool TryParseEnum (this int enumValue, out TEnum retVal) { retVal = default(TEnum); bool success = Enum.IsDefined(typeof(TEnum), enumVa...

It is entirely possible to write a PHP application almost entirely in an object-oriented methodology. You will have to write some procedural code to create and launch your first object but beyond that there are plenty of MVC frameworks for PHP that are all object-oriented.

C# .NET listing contents of remote files
Is it possible in.NET to list files on a remote location like an URL? Much in the same way the System.IO classes work. All I need is the URLs to images that are on a remote server.
Short answer: No, unless you have more control over that web-server Long answer: Here are possible solutions... You will need server-side script that will do it locally and output this list in your preferred format. Most of the web-servers implement default file-browsing pages, so you could theoretically parse those bu...

Textual versus Graphical Programming Languages

Before I arrived, our group (PhD scientists, with little programming background) had been trying to implement a LabVIEW application on-and-off for nearly a year.

php Zend / MVC without mod_rewrite

What can we do when we have an MVC framework (I am interested in ZEND) in PHP but our host does not provide mod_rewrite? Are there any "short-cuts"?

Zend framework should work without mod_rewrite. If you can live with your URL:s looking more like "/path/to/app/index.php/controller/action". If you had mod_rewrite you could do away with the "index.php" bit, but it should work with too. It's all a matter of setting up the routes to accept the index.php part.

In Cocoa do you prefer NSInteger or int, and why?
NSInteger / NSUInteger are Cocoa-defined replacements for the regular built-in types. Is there any benefit to using the NS* types over the built-ins? Which do you prefer and why? Are NSInteger and int the same width on 32-bit / 64-bit platforms?
The way I understand it is that NSInteger et al. are architecture safe versions of the corresponding C types. Basically their size vary depending on the architecture, but NSInteger, for example, is guaranteed to hold any valid pointer for the current architecture. Apple recommends that you use these to work with OS X 1...

You can use Sysinternal's FileMon. It is an excellent monitor that can tell you exactly which file-related system calls are being made and what are the parameters. I think that this approach is much easier than hooking API calls and much less intrusive.

Try the IE Developer Toolbar, which will let you inspect what is going on with the elements and give you outlines of the areas covered. It might give you a better understanding of the problem.

Can you explain closures (as they relate to Python)?
I've been reading a lot about closures and I think I understand them, but without clouding the picture for myself and others, I am hoping someone can explain closures as succinctly and clearly as possible. I'm looking for a simple explanation that might help me understand where and why I would want to use them.
Closure on closures Objects are data with methods attached, closures are functions with data attached. def make_counter(): i = 0 def counter(): # counter() is a closure nonlocal i i += 1 return i return counter c1 = make_counter() c2 = make_counter() print (c1(), c1(), c2(), c2()) # -> 1 2 1 2

In Cocoa do I need to remove an Object from receiving KVO notifications when deallocating it?
When I've registered an object foo to receive KVO notifications from another object bar (using addObserver:...), if I then deallocate foo do I need to send a removeObserver:forKeyPath: message to bar in -dealloc?
You need to use -removeObserver:forKeyPath: to remove the observer before -[NSObject dealloc] runs, so yes, doing it in the -dealloc method of your class would work. Better than that though would be to have a deterministic point where whatever owns the object that's doing the observing could tell it it's done and will ...

Flex: does painless programmatic data binding exist?
I've only done a bit of Flex development thus far, but I've preferred the approach of creating controls programmatically over mxml files, because (and please, correct me if I'm wrong!) I've gathered that you can't have it both ways -- that is to say, have the class functionality in a separate ActionScript class file bu...
Don't be afraid of MXML. It's great for laying out views. If you write your own reusable components then writing them in ActionScript may sometimes give you a little more control, but for non-reusable views MXML is much better. It's more terse, bindings are extemely easy to set up, etc. However, bindings in pure Action...

Best way to let users download a file from my website: http or ftp
We have some files on our website that users of our software can download. Some of the files are in virtual folders on the website while others are on our ftp.

HTTP has many advantages over FTP: it is available in more places (think workplaces which block anything other than HTTP/S) it works nicely with proxies (FTP requires extra settings for the proxy - like making sure that it allows the CONNECT method) it provides built-in compression (with GZIP) which almost all browsers...

Using GLUT with Visual C++ Express Edition
What are the basic steps to compile an OpenGL application using GLUT (OpenGL Utility Toolkit) under Visual C++ Express Edition?
If you don't have Visual C++ Express Edition (VCEE), download and install VCEE. The default install of Visual C++ Express Edition builds for the.Net platform. We'll need to build for the Windows platform since OpenGL and GLUT are not yet fully supported under.Net. For this we need the Microsoft Platform SDK. (If you're...

How to load plugins in .NET?

I'm using FBO s in my OpenGL code and I'm seeing compilation errors on GL\_FRAMEBUFFER\_INCOMPLETE\_DUPLICATE\_ATTACHMENT\_EXT. What's the cause of this and how do I fix it?

For example; with the old command prompt it would be: cmd.exe /k mybatchfile.bat
Drop into a cmd instance (or indeed PowerShell itself) and type this: powershell -? You'll see that powershell.exe has a "-noexit" parameter which tells it not to exit after executing a "startup command".

Using the mouse scrollwheel in GLUT
I want to use the mouse scrollwheel in my OpenGL GLUT program to zoom in and out of a scene? How do I do that?
Note that venerable Nate Robin's GLUT library doesn't support the scrollwheel. But, later implementations of GLUT like FreeGLUT do. Using the scroll wheel in FreeGLUT is dead simple. Here is how: Declare a callback function that shall be called whenever the scroll wheel is scrolled. This is the prototype: void mouseWhe...

fopen deprecated warning
With the Visual Studio 2005 C++ compiler, I get the following warning when my code uses the fopen() and such calls: 1>foo.cpp(5): warning C4996: 'fopen' was declared deprecated 1> c:\program files\microsoft visual studio 8\vc\include\stdio.h(234): see declaration of 'fopen' 1> Message: 'This function or variable may be...
It looks like Microsoft has deprecated lots of calls which use buffers to improve code security. However, the solutions they're providing aren't portable. Anyway, if you aren't interested in using the secure version of their calls (like fopen_s ), you need to place a definition of _CRT_SECURE_NO_DEPRECATE before your i...

Regex and unicode
I have a script that parses the filenames of TV episodes (show.name.s01e02.avi for example), grabs the episode name (from the www.thetvdb.com API) and automatically renames them into something nicer (Show Name - [01x02].avi) The script works fine, that is until you try and use it on files that have Unicode show-names (...

Cause: The stdlib.h which ships with the recent versions of Visual Studio has a different (and conflicting) definition of the exit() function. It clashes with the definition in glut.h.

Why are there so few modal-editors that aren't vi*?
Pretty much every other editor that isn't a vi descendant (vim, cream, vi-emu) seems to use the emacs shortcuts ( ctrl + w to delete back a word and so on)
Early software was often modal, but usability took a turn at some point, away from this style. VI-based editors are total enigmas -- they're the only real surviving members of that order of software.

64bit .NET Performance tuning
I know that.NET is JIT compiled to the architecture you are running on just before the app runs, but does the JIT compiler optimize for 64bit architecture at all?

The 64bit JIT is different from the one for 32bit, so I would expect some differences in the output - but I wouldn't switch to 64bit just for that, and I wouldn't expect to gain much speed (if any) in CPU time by switching to 64bit. You will notice a big performance improvement if your app uses a lot of memory and the ...

How to organize dataset queries to improve performance

How do I avoid using cursors in Sybase (T-SQL)?
Imagine the scene, you're updating some legacy Sybase code and come across a cursor.

Can I make Subversion + TortoiseSVN case-insensitive for Windows?
I've been using Subversion for code control with TortoiseSVN to interface with the server for the past few months, and in general it's been going great! However, occasionally my FoxPro IDE will change the case of a file extension without warning where " program.prg " becomes " program. PRG ") TortoiseSVN apparently tak...
Unfortunately, Subversion is case-sensitive. This is due to the fact that files from Subversion can be checked out on both case-sensitive file systems (e.g., *nix) and case-insensitive file systems (e.g., Windows, Mac). This pre-commit hook script may help you avoid problems when you check in files. If it doesn't solve...

Static Methods in an Interface/Abstract Class
First off, I understand the reasons why an interface or abstract class (in the.NET/C# terminology) cannot have abstract static methods. My question is then more focused on the best design solution. What I want is a set of "helper" classes that all have their own static methods such that if I get objects A, B, and C fro...
Looking at your response I am thinking along the following lines: You could just have a static method that takes a type parameter and performs the expected logic based on the type. You could create a virtual method in your abstract base, where you specify the SQL in the concrete class. So that contains all the common c...

How to retrieve a file from a server via SFTP?

If you only want one answer from the group, then a RadioButton control would be your best fit or you could use the ComboBox if you will have a lot of options.

How to add "Project Description" in FogBugz?
When I create a new project (or even when I edit the Sample Project) there is no way to add Description to the project. Or am I blind to the obvious?
There's no such thing as a project description, really. There's a column in the Projects page which is used so you can see which project is the default, built-in inbox, and we couldn't think of anything better to put as the column header for that column.

No, it's not possible to cache https directly. The whole communication between the client and the server is encrypted.

Suppose you have the following EJB 3 interfaces/classes: public interface Repository { public void delete(E entity); } public abstract class AbstractRepository implements Repository { public void delete(E entity){ //... } } public interface FooRepository { //other methods } @Local(FooRepository.class) @Stateless pub...
I tried it with a pojo and it seems to work. I had to modify your code a bit. I think your interfaces were a bit off, but I'm not sure. I assumed "Foo" was a concrete type, but if not I can do some more testing for you. I just wrote a main method to test this. I hope this helps! public static void main(String[] args){ ...

How to get started with speech-to-text?
I'm really interested in speech-to-text algorithms, but I'm not sure where to start studying up on them. A bunch of searching around led me to this, but it's from 1996 and I'm fairly certain that there have been improvements since then. Does anyone who has any experience with this sort of stuff have any recommendations...
This is a HUGE questions, I wouldn't know how to begin... So let me just try giving you the right "terms" so you can refine your quest: First, understand that Speech Recognition is a diverse and complicated subject, and it has many different applications. People tend to map this domain to the first thing that comes to ...

Mixed C++/CLI TypeLoadException Internal limitation: too many fields
On a quest to migrate some new UI into Managed/C# land, I have recently turned on Common Language Runtime Support (/clr) on a large legacy project, which uses MFC in a Shared DLL and relies on about a dozen other projects within our overall solution. This project is the core of our application, and would drive any mana...
Make sure the Enable String Pooling option under C/C++ Code Generation is turned on. That usually fixes this issue, which is one of those "huh?" MS limitations like the 64k limit on Excel spreadsheets. Only this one affects the number of symbols that may appear in an assembly.
