Arrays in VB .NET 2012 1

[IlyaRabyy]

Colleagues,
Again, as a former VFP programmer, I'm used to have multi-dimensional arrays to hold different data types in different columns, e.g.

DECLARE ARRAY laValues[3, 5]
FOR I=1 TO 5
   laValues[I, 1] = I
   laValues[I, 2] = ".\WrkDir\Wrk" + STR(I)
   laValues[I, 3] = .F.
NEXT I

that is 1st column has Int, 2nd - String, 3rd - Boolean.

Is two-dimensional array in VB .NET able to hold different data types in different columns too?
If so - please tell me how to.
TIA!

Regards,

Ilya

Yes, it can./ Simply declare in VB without a datatype, e.g:

[blue]    Dim laValues(5, 3)
    For I As Integer = 1 To 5
        laValues(I, 1) = I
        laValues(I, 2) = ".\WrkDir\Wrk" + Str(I)
        laValues(I, 3) = False
    Next I[/blue]

Note that VB arrays are 0-based, whilst FFP arrays are 1-based, so you may need to refactor your code slightly

Thank you StrongM!
I thought that with .NET MS made VB strong-typed...
As for 0-based, I recall there was some setting/option in pre-.NET VBs where one could make it 0- or 1-based.
I tried to find it in the VB .NET VS 2012 - and could not.
Is it still there?

>there was some setting/option

Yes, in classic VB there was [tt]Option Base[/tt], which allowed you to modify this. It does not exist in VB.NET, which is why I made the point.

... in classic VB there was Option Base ... It does not exist in VB.NET

Alas!
Thank you, colleague!
