![]() ![]() The assembly defines a FixedLengthString type which behaves like fixed-length strings, but there are significant differences with the original VB6 type. VB.NET doesn’t support fixed-length strings. VB6 fields, local variables, and members of Type structures can be defined as fixed-length strings, as in:Īn uninitialized fixed-length string initially contains only ASCII 0 characters when you assign any value to it, the value is truncated to the maximum length, or padded with spaces to the right if shorted than the maximum length. However, it is recommended that you get rid of type declaration suffixes and convert them in standard and more readable As clauses. Now a variable whose name ends with “%” is a 32-bit integer a variable whose name ends with “&” is a 64-bit integer a variable whose name ends with is a Decimal variable. ![]() Type declaration suffixesĪ consequence of the fact that VB.NET redefines the meaning of Integer and Long keywords is that the meaning of type declaration suffixes has changed too. NOTE: starting with version 1.52, the VB6Variant class is not officially supported. ![]() VB Migration Partner offers the option to render a Variant variable with the special VB6Variant type, if a SetType or ChangeType pragma is specified. NET variable can’t hold the special Empty, Null, and Missing values. In many cases, however, the two types aren’t equivalent. VB.NET doesn’t support the Variant data type all Variant members are translated to Object members. For example, in VB6 a Currency operation might raise an overflow, but it would be evaluated correctly under VB.NET. However, the Decimal data type has greater precision and range than Currency, therefore you have no guarantee that math expressions deliver the same result they do in VB6. The Currency data type isn’t supported by VB.NET variables of this type should be converted to Decimal. (A VB.NET Long variable is a 64-bit signed integer.) A VB6 Integer variable is a 16-bit signed integer, therefore it should be translated to Short under VB.NET likewise, a VB6 Long variable is a 32-bit signed integer and should be translated to Integer under VB.NET. ![]()
