• Code Golf: Numeric Equivalent of an Excel Column-Name

  - by Vivin Paliath

  Can you figure out the numeric equivalent of an Excel column string in the shortest-possible way, using your favorite language? For example, the A column is 1, B is 2, so on and so forth. Once you hit Z, the next column becomes AA, then AB and so on. Rules: Here is some sample input and output: A: 1 B: 2 AD: 30 ABC: 731 WTF: 16074 ROFL: 326676 I don't know if the submitter is allowed to post a solution, but I have a Perl solution that clocks in at 125 characters :).

• Visual Studio 2010 Sku upgrade. From Professional to Ultimate

  - by josecortesp

  I have installed Visual Studio 2010 Professional (final version), with some components, plug-ins and templates I use a lot.

Thanks in advance

• Ajax and gridviews

  - by Dofs

  Hi, can any of you recommend a good ajax gridview for asp.net? I have looked at telriks, but 1000$ is a bit too expansive for my taste. I don't need a whole lot of features, but rather it to be fast.

• Do any JS implementations currently support (or have support on the roadmap for) fast, vectorized op

  - by agnoster

  I'd like to do a bit of matrix/vector arithmetic in JavaScript, and was wondering if any browsers or other JS implementations actually have support for vectorized operations, for instance for quickly summing the entries of two Arrays (or summing, or whatever). Even if that currently doesn't mean it compiles down to vectorized operations, at least some language support would be nice for when it does get implemented - I'd take the existence of functions or syntax to support it as a step in the right direction. (Understandably, "vectorization javascript" searches are pretty much all about graphics and SVG.)

• Multiple inheritance in OOPS

  - by user145610

  I'm confused about an OOPS feature, multiple inheritance. Does OOPS allow Multiple Inheritance? Is Multiple Inheritance a feature of OOPS? If Multiple Inheritance is a feature then why don't languages like C#, VB.NET, java etc. support multiple inheritance? But those languages are considered as strongly supported OOPS language. Can anyone address this question?

• Why do ASP.NET applications appear to be running in a terminal server session?

  - by Heinzi

  Running the following ASPX page (IIS 6, Server 2003 R2) <%@ Page Language="vb" AutoEventWireup="false" %> <% Response.Write("Am I running in a terminal server session: " & _ System.Windows.Forms.SystemInformation.TerminalServerSession) %> yields the following output: Am I running in a terminal server session: True Why? IIS is running as a service, not as a Terminal Services application... (BTW, according to Reflector, SystemInformation.TerminalServerSession is just a wrapper for GetSystemMetrics(SM_REMOTESESSION).)

  The company I work for has decided to join the 21st century and upgrade our main database cluster from SQL Server 7 to SQL Server 2005.

• Could MacRuby / HotCocoa supplant the need to know Objective-C?

  - by frou

  I just discovered MacRuby / HotCocoa and really like the sound of what they're doing. I had essentially discounted the prospect of making Cocoa GUI applications myself because I have an aversion to spending time & effort learning yet another C-based language, Objective-C. I'm not saying it's bad, just not for me. Is it the case now, or in the probable future, that one will be able to make Cocoa GUI applications of substantial and first-class nature with MacRuby / HotCocoa alone while ignoring Objective-C completely?

• What's missing in Cocoa?

  - by Bridgeyman

  If you could add anything to Cocoa, what would it be? Are there any features, major or minor, that you would say are missing in Cocoa. Perhaps there is a wheel you have had to invent over and over because of an omission in the frameworks?

• Protect .NET code from reverse engineering?

  - by Priyank Bolia

  Obfuscation is one way, but it can't protect from breaking the piracy protection security of the application. How to make sure that the application is not tampered with, and how to make sure that the registration mechanism can't be reverse engineered. Also it is possible to make to convert C# app in native code, Xenocode is too costly. C# provides lot of features, and is the ideal language for my code, so writing in C++ again the whole codebase is out of question. Secure certificates can be easily removed from the signed assemblies in .NET

• Running CPython Applications With Visual Studio?

  - by user213060

  I would like to know how to use Visual Studio with CPython (the official python.org python interpreter, not IronPython). In particular, I am interested in getting "build" and "run" commands in Visual Studio working. Other features such as color highlighting and auto-complete, I am less concerned about. Also, can the "build" command be made to run py2exe or similar exe packagers?

• Where can you find fun/educational programming challenges?

  - by tj9991

  I've searched around for different challenge sites, and most of them seem to be geared towards difficulty in problem solving logically, rather than trying to use your language of choice to do something you haven't used it for. Their center is around mathematics rather than function design. Some kind of point system for correctly solving challenges, or solving them the most efficient/smallest would be neat as well.

• How does Appcelerator Titanium Mobile Work?

  - by Darrell Brogdon

  I'm working on building an iPhone app with Titanium Mobile 1.0 and I see that it compiles down to a native iPhone binary. How does this work? Seems like it would take a lot of heavy lifting to analyze the JavaScript code and do a direct translation into Objective-C without having a subset language like 280 North's Objective-J and Cappuccino.
