Language selection : C# or vb.net

Hi,

I have an application which comprises of several components developed using C# (it includes WCF and other web services implementation). For integration testing, I have the language options of C# and vb.net. As I know except syntax difference between them, nothing is different, but as per my personal opinion, its better to use a language for testing which already used for development.

Please share your thoughts and comments on the same and also let me know if there is any pros/cons using c# or vb.net.

Thanks,
Jay

I see no reason to mix languages unless there are compelling technical reasons to do so. If the project has been developed in C# then stick to it.

Unless you have some special technical reasons for using a different language just stick to the same one.

If you don't have any personal preference then I'd go for C# because:

1. There are generally more samples and snippets on the web in C#.
2. VS IDE editor support is better implemented in C# than VB.

Technical differences are minor and going forward C# and VB language feature differences are narrowing.

C# vs VB

I am a C# developer mainly, but I have been looking at some VB code recently. I thought that they were pretty much the same because they compile to similar things, but I'm starting to think that C# is much better. Maybe I'm not giving it a fair chance because I haven't spent much time on it? I was expecting to like it, and had an open mind, but there are some things which I really dislike.

The first thing I don't like is the weak typing. I saw these

myVar = "-1"<br />
myVar = -1

This really scared me, I found it quite confusing looking at the code.

The syntax also doesn't look nice to me, but that's really a personal preference. I'm should there will be lots of opinions, but do you think it's reasonable for me to dislike VB?

If not, then apparently I'm unreasonable too Smile | :)

I don't like it at all, but I haven't tried it, and I
come from many many years of C/C++ so C# is natural to me.

yeah, it is very reasonable. Don't hesitate, go for the real language.

BTW: there are some options that are off by default, if you insist on using VB.NET, turn them on (e.g. Option Strict[^]).

Each language has its own lovers and haters, so does VB. I had been programming in VB for more than 6 years when I changed to C#.

But history tells us that VB is the language that has the shortest learning curve.

And there are certain features that VB.NET provides out-of-the-box that C# cannot do "neatly", for example, single instance desktop applications.

I don't see what isn't neat about this: http://www.ai.uga.edu/mc/SingleInstance.html[^].

Just because C# doesn't provide tick box for it doesn't mean you can't do it.

The choice in language is entirely down to personal preference, there is no significant technical difference.

I you had ever tried one of those solutions, you would realize that all those articles on the internet that teach how to create a single instance desktop application in C# just try to find out if the app is already running and then display a message box that reads "App is already running". I am yet to read any article that teaches how to "neatly" activate the already running instance (without using Microsoft.VisualBasic namespace and AppActivate method). I tried using Win API and P/Invoke but no luck Frown | :-(

VB.net is not weak typed. It is strongly typed just like C#.

However, the vb.net compiler does not enforce strict type conversions at compile time in the way the C# compiler does. This means that you are able to directly place an Int in a String object and VB will automatically apply the type conversion. It's still strongly typed, the type is still a String, and the int being placed into it will be cast to a String, it's just casts can happen implicitly.

You can use the Option Strict[^] setting to change this behaviour and make the compiler act more like the C# one.

Either way, the coder is still free to ignore type usage (equally as they could in C# by declaring everything to be an Object).

In terms of the language, both are equally capable and equally well supported. The language choice is almost entirely down to personal preference. There is no really significant technical difference between the two.

All that said, I personally prefer C# too.

IDE editor support is better in C# IMO but that's a usability rather than a technical difference.

The Option Strict off by default was a really lousy decision. I've been bitten by this numerous times when working on VB projects.

Other people don't like VB.NET, C# or C++, and opt for Python, Ruby or even Pascal[^].

So you're not so sharp on VB. The *cool* news here is that you can team up with a VB.NET programmer, even if he/she isn't too keen on C# - you can both write your .NET classes in your own language Smile | :)

Metafile: BUG in PlayRecord???? EnumerateMetafile VS Drawimage !!!!

Hi, I hope to post in the right forum ..

I need to control and modify the drawing of a Windows Enhanced Metafile so, as a test, I
tried code from the following MSDN article.
http://msdn.microsoft.com/en-us/library/system.drawing.imaging.metafile.playrecord.aspx[^]
NOTE...All Platforms and Supported in: 3.5, 3.0, 2.0, 1.1, 1.0

Result: I have not done many tests but i can say: working in W2000, W2003 Smile | :)

, not in XP and Windows 7.... Mad | :mad:

Note: .NET 3.5sp1 in all update PC's

I've try with this simple file, a red rectangle with gradient,
http://rapidshare.com/files/301791141/rosso.emf[^]

and, for the lazy the whole small program...
http://rapidshare.com/files/301791802/WindowsFormsApplication2.zip[^]

Finally, if we use DrawImage instead of EnumerateMetafile, ...that's works fine!!!!!

(more in details e.Graphics.DrawImage(metafile, destPoint);)

Can you help me????

This may be exactly what you're looking for:
~~http://www.sergemeunier.com/blog/tutorials/astronomical-calculations-in-c-sharp/~~

Updated link 2011:
http://www.smokycogs.com/blog/tutorials/astronomical-calculations-in-c-sharp/[^]

The download is the non-obvious "here" link on the page that combines all of the sample code into a single app called Urania.

Once downloaded, you will also need to modify the Urania.sln file to fix the paths of the different libraries that he uses (MathLib, UraniaLib, etc.) and then it will compile correctly.
(open Urania.sld in notepad and delete: "..\Libs\" out of the 3 project paths)

Korean Localization problem

Hi all,
I'm building a virtual keyboard in c#.
My problem is when I set the keyboard for korean input, I can't retrieve korean keyboard chars to display on my keyboard.
I use LoadKeyboardLayout API call to get the korean keyboard layout, and then I use ToUnicodeEx to get keyboard characters symbols. This doesn't work for korean characters. For other languages (such as german) this works fine.
What do I need to do in order to be able to retrieve korean characters?
Thanks...

Hi
i am developing an application which will run on Dolphin 6100 (A smart device running on windows CE 5.0).
this application is a windows CE 5.0 application, which will interact with SQL Server 2005 Express database(installed on database server accessible through wireless access pint) and do some stock updates.

I am currently working with VB 6.0 and do not have enough time to learn VB.NET . could any one please translate this little piece of VB 6.0 code into windows ce 5.0(visual studio 2005) code.

Dim cn As New ADODB.Connection
If cn.State = 1 Then cn.Close
cn.Open "connection string for SQL server 2005 express" ?????????
Dim rs As New ADODB.Recordset
If rs.State = 1 Then rs.Close
rs.Open "select field1,field2 from TStock", cn, 2, 3
rs![field1]=some thing
rs.update
rs.close
cn.close

Specially i need connection string to connect to SQL Server 2005 Express from my windows ce 5 based smart device.

thanks and regards.

Hi,

connection strings need a server name; WinCE isn't any different in that.
