what is the default data type in vb
Variant type In Visual Basic (and Visual Basic for Applications) the Variant data type is a tagged union that can be used to represent any other data type (for example, integer, floating-point, single- and double-precision, object, etc.) except fixed-length string type and record types. In Visual Basic, any variable not declared explicitly or the type of which is not declared explicitly, is taken to be a variant.
