I have been tasked to rewrite an old excel workbook that is full of ugly vb macros. It is mostly some simple data entry, and some reporting functionality on top of that. I am not super experienced with Excel, but I can get around.
I know that visual studio has project types for excel, but I am not really sure what is possible. I am a c# developer, and would greatly prefer that to crappy vb macros.
Are there any resources for learning to write plugins and workbooks in c#? Google does not seem to be helping me very much. I really just need a few good examples and I should be good to go?
I generally can't find many good resources for excel in general either? Most are old or unhelpful. Any recommendations?
I do a lot of spreadsheet manipulation in c# via the COM interface. You can find examples and more information from MS here.
If your spreadsheets are simple, you can also use ADO.Net interfaces (described here) but I never could figure out how this would work for non-simple worksheets.
Here is a Microsoft knowledge base article on using interop to automate Excel.
I just stumbled across Excel-Dna yesterday, and it looks like a very promising way to use VB.NET/C# in a UDF/macro capacity within Excel. I haven't had a chance to try it yet, but it seems to be actively maintained and has an active mailing list.
I am trying to find some code which shows how one might open an Outlook NK2 names cache file. I did some searching and I have seen several people say that it's not possible, but then I find links to some freeware that can do just this so I know its possible. I would use the freeware applications, but would rather do it in my own code, and it easier to get an approval from management if I use my own code within my organization rather then a freeware/shareware application. I'm trying to write the code in VB, but I would like to find a example in any language if it helps.
Redemption has some Nk2 examples, although you may have to pay for a commercial license.
There is also a project on Google Code that has a lot of good stuff in it to get you started.
Some years ago I used to program in VB6, I really liked it because it was very simply and fast, when VB.net came out, I abandoned it because they changed a lot of things.
I wonder if after all this years there's a new language or IDE that helps programming in an easier and faster way than VB6.
I'm not very interested in academic/personal issues like, very high performance, great movility through OSs, open source, etc. I would like to know if there's is something to program small and medium desktop apps. in an very easy and fast way.
Excuse me if my english isn't very clear.
Edit answering Nicholas:
Well, I must admit that I didn't try VB.Net too much, I was a little disappointed because I would had to learn a lot of new things and I've had learned VB6 not so long before (in that moment).
VB.Net is the natural progression of VB6, and has a lot of free tools and resources online to get started. Microsoft even provides a free development environment as well as a free database for development/bundling in your applications.
Check out this website for information and download links on all the free Microsoft software.
Also, you said you tried VB.Net and didn't like it-- I'd be curious to know why? Yes, there's a little learning curve, but the abundance of getting started information on the internet surely can help that. I was a bit overwhelmed by .NET at first (particularly ASP.Net) not seeing the value in switching/learning a new language.
I always felt Microsoft Access was far and away the best for this kind of requirement.
edit - I realize this isn't a politically correct answer. But the total package of a built in DB, a great GUI development package, a great report generator (far superior to crystal reports, for example), the easy development of tables and queries, all put in one friendly package, make it nearly trivial to develop with. For rapid development, it's the best I've used.
FWIW, I do Java, C++, C, VB4/6, ASP, JSP, Perl, PHP, CSS/ DHTML, JavaScript, Pascal, Fortran, Kenemy and Kurtz Basic, BAL, unix shell scripting, Oracle, mySql, RPG III, COBOL, some proprietary stuff, various macros, various distributed technology, Job control language, CPL, etc. etc. I got out of developing in Access because of scalability limitations.

One of the easiest languages to learn and use is Python.
FLEX / AS3 / MXML / AIR (tnx le dorfier) comes very close to that VB6 feel from many years ago. But understands stuff like CSS and produces output that works in browsers on any platform (or desktop with AIR). You write code and run it, the coding cycle is very fast. And AS3 is at least as powerful as VB6 ever was, plus there are myriad add-ons and libraries to support all sorts of applications, all the major web-services, database interface, animation, video, 3D, auto-generation of PHP code, etc.etc.etc...
And Flex Builder 3 is free for students and educators.

Python or Ruby.
Dynamic languages has a number of advantages (and disadvantages) but for what you propose they seem perfect.
I would recommend python or ruby bindings of a high level toolkit as a perfect environment. For instance Qt library gives most functionality you would need and dynamic languages let you easy experimentation
Microsoft has a new dialect of BASIC called Small Basic. From the website:
Small Basic is ... a small and easy to learn
programming language in a friendly and
inviting development environment,
Small Basic makes programming a
breeze. ...
Small Basic derives its inspiration
from the original BASIC programming
language, and is based on the
Microsoft .NET platform. It is really
small with just 15 keywords ...
The Small Basic development
environment ...provides
powerful modern environment features
like Intellisense™ ...
The first two versions of VB.NET had serious shortcomings compared to Visual Basic 6. However most of these issues has been fixed since Visual Studio 2005. Today, for new projects, I feel that everything that made VB6 so easy to use is available with VB.NET plus you get new language constructs, and the .NET framework. There also refactoring, and the VB Power Pak which brings back the older simple to use print engine.
Of course there is a learning curve involved. But no more than the leap from QuickBASIC/PDS to VB 1. If you have to maintain or transfer an older project then the differences between VB6 and VB.NET are much more serious.
Finally there is the Mono Project which support the VB compiler. This provides a degree of relative immunity from Microsoft deciding to break backwards again.
You could try FreeBASIC.
It's syntax is very similar to that of VB and it is an actively worked on open-source project, it is also portable across different platforms.
You can grab a download here and there are several exemplary works that can be found here.
If it already wasn't done I'd recommend python. It's one of the easiest languages to learn.
My first language was Pascal and I think it's also one of the easiest languages and with Delphi getting popular again I think it's a very good alternative to VB6.
I've always found Delphi to be easier than VB despite popular belief.
take a look at Lua
very small core language, the whole documentation is a single (very readable) webpage. you can easily learn the basics in a weekend.
very good (small) books with good tips.
very helpful community.
very fast, both with the standard bytecode VM, and the JIT.
used a lot in games, both because it's fast and easy to embed in the application, and because it's easy to explain to players interested in extending the game.
readable sources.
MIT license, use for whatever you like, no strings attached.
Perhaps Clarion is what you're looking for? Personally, I don't have much experience with it, but you can build some nice apps with virtually no coding skills.
I think C# is a very good language to program GUI apps quick and easy.
While this might not be a complete answer to your question, I would recommend spending some time learning a more complex language (Objective-C, Java, C#, etc). With the experience you learn with OOP design patters etc, in the future you won't have to shop around for the "easiest" language to program with.
visual basic.NET is much more easier and have complete features than VB6 as I've experienced.
I recently messed around with Microsoft Lightswitch and found it extremely VB like. Very fast for binding to a database and generating forms, grids, etc.
More than 10 years after this question was asked, the best answer is...
...to continue using the VB6 programming language.
VB6 still works on Windows 10 and Windows Server 2019. Just as it has since Windows 98.
Microsoft's support policy for VB6 is here VB6 support policy
What real-world projects would you suggest looking through the sources?
As I'm learning Java Swing, mucommander seems to be a decent example. The code is excessively commented though.
EDIT: No shameless plugs plz :).
I learned a lot from looking at the source code to GoGrinder. It's well thought out, uses MVC correctly, and the comments are helpful (and no, I didn't write it). It's also a fun program to use if you want to learn how to play Go.
For Gui design, Patterns and general good advice I highly reccomend Jeremey Miller's series of articles on building a better CAB. For C#, but equally applicable to Java. Also using
the MVC style which Stackoverflow follows, and Apple uses for Interface Builder.
Build your own CAB
Jeremy's articles/ideas are followed in his own project, which you can download and inspect at http://storyteller.tigris.org/
Take a look at the Windows version of truecrypt. It is one of the best organized open source projects I've ever seen. You can almost tell how the whole thing works just from the directory and file layout.
What I've done to learn some new technologies over the years is to look to open source projects that both match the criteria you're looking for and also interest you.
I'm not a Swing guy, but I'd suggest finding a project that uses Java Swing, does not appear too complicated, and then start digging through the source. The nice thing is you can then see the app before you start poking through it, and then you can see what happens as you change stuff.
The idea behind picking something that interests you is that it will keep you engaged. I am intrigued by content management systems, so I might download a CMS that I can then see how stuff works, and I'm engaged because the problem domain of the project fits in with an interest.
I've done this once or twice when I had to get up to speed on C# and I think it works will. YMMV....
Some of the most well thought out source code ( c++ ) I have seen in an open source project is the Ogre3D graphics engine, I've learned a lot about OOA&D just by looking at the structure and reading the comments. It is also well maintained and the community is very active.. http://ogre3d.org
OK,
I want to create a windows shell extention that sits in the file menu much like the "Tortorise SVN" menu.
Does anyone know where I'd begin, a good article, or what interfaces to implement?
Thanks!
It's pretty straight forward actually. It's about a 3-4 step process. You didn't specify what language you were using.
Here's how to do it in native code:
http://www.kbcafe.com/articles/HowTo.Shell.pdf
Here's how to do it with .NET. Note that it is essentially the same as doing it with native code.
http://www.theserverside.net/tt/articles/showarticle.tss?id=ShellExtensions
Ah... Shell extensions... they can be a real pain in the butt if they're complicated, but you can do so much neat stuff. A great place to start is Mike Dunn's Complete Idiot's Guide To Writing Shell Extensions on codeproject.com.
There's an O'Reilly book called VB Shell Programming which goes into the API's in some depth. As the title suggests, it's aimed at Visual BASIC, but the API's are exposed through COM and the techniques discussed in the book are applicable for pretty much anything that supports COM. A quick look on Amazon.com suggests you can probably pick up a secondhand copy for a few dollars.
Avoid codeproject (for kids, full of bugs) and read the complete doc of MSDN on SNE.
