String length when converting from a character array

Question

I\'m having serious problems with string-handling. As my problems are rather hard to describe, I will start with some demo code reproducing them:

Dim s1 As S         


        

Answer 1

You can either Dim or ReDim the char array once you know the length of the s1 string.

Dim s1 As String
s1 = "hi"
Dim c(s1.Length) As Char
c(0) = "h"
c(1) = "i"
Dim s2 As String = CStr(c)

And now your comparison will work no matter the length of the original string. You didn't state whether the length of 30 for 'c' is a requirement or not here.

But even if it was, you'd still need to either expand or contract the array to have the same CStr length to do your comparison.

So even after declaring

Dim c(30)

You can later in the code block redimension the array like this

ReDim c(s1.Length) 'Or any int value you like

If increasing you can precede with the preserve keyword, which will expand the array while maintaining its current contents.

ReDim Preserve c(s1.Length)
