Hi There,

When the loop starts, I got the following error.
"Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index"


Private Shared MAXLENGTH As Integer = 94
Public Shared SPACE As Byte = CByte(&H20)


Private strBuilder As StringBuilder

Me.strBuilder = New StringBuilder(Record.MAXLENGTH)

            For i = 0 To Me.strBuilder.Capacity - 1
                Me.strBuilder(i) = ChrW(Record.SPACE)
            Next


Please advice.

Thanks.

Please try the following:

Private Shared MAXLENGTH As Integer = 94
Public Shared SPACE As Byte = CByte(&H20)


Private strBuilder As StringBuilder

Me.strBuilder = New StringBuilder(String.Empty.PadRight(MAXLENGTH), MAXLENGTH)

Open in new window

Your StringBuilder is empty.

Me.strBuilder(i) is a shorthand for Me.strBuilder.Chars(i).

Since there is no text in the StringBuilder, there is no Chars, and you cannot reference the first character. If you simply want to fill it in to work in it later, you can use the following:

Me.strBuilder = New StringBuilder(New String(" "c, MAXLENGTH),Record.MAXLENGTH)

If you want to fill it with something else than spaces, use it's Append method. to build it.

If all you only want a string of a given length, use the following String constructor instead:

Dim s As  New String(" "c, MAXLENGTH)
