Visual Basic Strings

Posted by Muhammad Ali Shah on 1999-08-10

Hello All,

Since  there are no posts for the last few days, I have another question for
VB programmers. How exactly a string is handled in Visual Basic? In more
appropriate terms, I would like to know:

1. In Pascal we have fixed length strings that have length stored in the
first byte. In C language, the strings are null terminated. What exactly is
a string in VB?

2. What is the difference between "Dim aStr as string" and "Dim aStr as
string * 20"?

3. Why can't I read/write data to a file with the following structure
TYPE employee
   dim name as string
   dim age as integer
END TYPE

If however, I use fiexed length strings, the read/write functions do exactly
what they are intended.

All the best...
Ali.
