VB 2010 functions

Question

As a pro VB6/SQL server developer I recently downloaded VB2010 and bought Alessandro Del Sole's VB 2010 unleashed book.

The book details all the new functions / methods such as string.contains etc. Having practiced a little I discover that VB 2010 still has reference to VB6 functions such as Instr() (which by the way seems to give a different result from "string.contains")

My question is should we be using the new 2010 methods / functions or is it still OK to use the V 6 equivalents such as Instr instead of contains? Will the functions such as Instr() and Right() etc. be deprecated and if so, is there a time frame for doing so.

Thanks

Hi,

Most of the regulars forum contributors here would probably recommend using the newer methods.

In the newer VB.Net methods all STRING operations are zero based as far as I know too, so be careful.

 

ALL of the ( VB6 ) older ones reside in the Microsoft.VisualBasic namespace as far as I know.

 

I hope this helps.  :)

Those functions are not going to be deprecated.  They are a core part of the Visual Basic language - as such they are perfectly acceptable to use.  That said, I would be familiar with the framework methods as well - since, it makes it easier to transition to other languages should the need arise :)
