Basic question about Dim statement??? 1

[steve728]

Two questions about the following:

Dim s, fldCode$

1. What happens when you don't define the datatype like above?

2. What does the $ signify at the end of a memvar?

Thanks,

If you don't give a type it is defined as variant. Do some searching on late binding versus early binding.

In VB.NET an untyped variable is treated as an Object. There is no Variant datatype in VB.NET.

The $ on the end of a variable name will cause it to be assigned as a String.

Ooops...thought I was in the wrong forum. My apologies.

Depending on the options you have set for your project, not giving a variable a type will cause an error. Option Explicit on forces you to declare a type for your variables.

BTW if you don't set Option Explicit then if you forget to declare the type of a Function it will also default to Object and not give you an error.

Found that one by mistake!
