Discussing something weak of Visual Basic.NET

[vnInformatics]

Hi everybody,

Perhaps this topic has been discussed with thousands of whitepapers since appearing.... But In this topic, I still want to discuss some aspects week when coding the application.

Right now, I have been developing my first project. That is why I am wondering about the Visual Basic.NET. Could you please help me point out something what I should strongly take care about the application.

- How about securing application.
- What aspects I should use Visual Basic.NET( ex: Database, Networking....)
- ect....


Thanks for sharing experiences.
I am looking forward to hearing any suggestions.

As the following article says, "Efficiency Is the Key".

If you don't understand what's happening below the surface, nothing else really matters.

Luckily, I have been coded some simple programs in Assembly Language before. Actually, I had learned Pascal so carefully before -> Therefore, when I coded the program, always in my mind I had to calculate how many bytes in memory I should use...


But, when I switch programming languages to Visual Basic.NET. I really shock becuase..in the dos programs is provided the limited bytes of memory, but in windows programs I can use more than 65,356 bytes....

For this reason, I really donot take care of how many bytes should I use....and also how long does the processor take when implement arithmetic so much...( except: AndAlso, OrAlso ...)

Thanks for sharing this article.

Could I aske you one more thing: How about security in Visual Basic.NET and What is the strongest aspect in Visual Basic.NET ?

Looking forward....:D

In addition, When I swith some "Dos Languages" as: Assembly, Pascal, C/C++ to to "Windows Languages" as: Visual Basic.NET. I couldnot appreciate how the processor interpretes the syntax. Such as: Buttons, MenuItems, Menu, DataGrid, DataSet...ect..( Object ).

In Dos Languages, I can understand how arithmetic the processor implements as well as how long does the processor take....For "Windows Languages"...In fact, I donot know what is underlying of the "Object" and how it works...???

Could you please tell me more about Visual Basic.NET...?
Thanks for sharing your experiences....

P/S: It is the first time, I am assigned to develope an application by using Visual Basic.NET. I donot have much time to find out about VB.NET, just "leaning by doing".:thumb:

How about security in Visual Basic.NET and What is the strongest aspect in Visual Basic.NET ?

1) Security is a major player in the .NET Framework, read about security here. (http://msdn.microsoft.com/security/securecode/dotnet/default.aspx) As you will read, there is a good amount of security "enabled" by default in the framework, which also means there is a small performance penalty when you use secured components.

2) In my opinion, the strongest aspect of the VB.NET is that it uses the .NET Framework. There are a lot of benefits to be had from using a managed language, especially when using a RAD language (VB, C#, etc..).

3) "Object"s: Object Oriented Programming (OOP) (http://en.wikipedia.org/wiki/Object-oriented).

4) VB.NET Description (http://www.gotdotnet.com/team/vb/):
While providing the traditional ease-of-use of Visual Basic development, Visual Basic .NET also allows optional use of new language features. Inheritance, method overloading, structured exception handling, and free threading all make Visual Basic a powerful object-oriented programming language. Visual Basic .NET fully integrates with the .NET Framework and the Common Language Runtime, which together provide language interoperability, simplified deployment, enhanced security, and improved versioning support.
