Hi
I have a string which is at least 4 characters but can be more which I need
to pad, with zeros, to a full length of 15 after the 3rd charactor.
Eg '1234' to '12300000000000 4'
How can I do this?
Also how can I truncate this back to 4 or however many charactors (e.g.
123000000000400 = 123400)
Any help will be much appreciated
Thanks

Eg '1234' to '12300000000000 4'
How can I do this?
1. split the string into "123" and "4" (check out String.Substrin g())
2. pad the second string (check out String.PadLeft( ))
3. concatenate the two string (check out String.Concat() )
Also how can I truncate this back to 4 or however many charactors (e.g.
123000000000400 = 123400)
remove the 4th character from your string (check out String.Remove() ) while
it equals "0" (while loop with String.Equals() ).

I suggest to use the '&' operator for string concatenation instead of using
'String.Concat' .

Readability is better when using '&':
\\\
Dim s As String =
"Hello " & Name & "," & ControlChars.Ne wLine
///
vs.
\\\
Dim s As String = _
String.Concat(" Hello ", Name, ",", ControlChars.Ne wLine)
///

Diana,
In addition to readability as Herfried suggests, the & operator will
concatenate any constants at compile time. String.Concat is strictly a
runtime function.
Const format As String = "Hello" & ControlChars.Ne wLine & "World"
When dealing with Object variables (parameters really) & Option Strict On
String.Concat is useful:
Option Strict On
Dim i1 As Object = 1
Dim f1 As Object = 1.0F
Dim d1 As Object = 100D
Dim s1 As Object = "help"
Debug.WriteLine (i1 & f1 & d1 & s1)
Debug.WriteLine (String.Concat( i1, f1, d1, s1))
The first statement is a compile error, while the second succeeds, both
should return the same result! As String.Concat is overloaded for both
String & Object!
Hope this helps

How can one format an integer into a hex string with leading zeros? Suppose
an integer is 512 which in Hex is 200. I wish to print the 4-byte integer
as 0200 or even 0x0200. The HEX function doesn't create leading zeros. The
Format function (format(value,"X") doesn't create leading zeros.
I believe there should be a simple way that doesn't involving measuring and
padding the string.
