Modifying an array based on a structure within a function

[banedon]

Hi guys

I've run into a bit of an issue which I'm struggling with and wonder if anyone can give me an idea of what I'm missing.

I have an array based on a structure which in turn has three string values. I'm unable to use Replace to remove or replace a character in one of those strings (.Value) - it does nothing.
If I manually loop through the string and look for the the character to be replaced, I can delete or replace without issue.
I get no errors and the code continues on - just Replace has no effect.

Any thoughts? Is this an issue due to Replace not being able to dela with the structure?


Here's the code in question (only):

Public Module Module_Definitions
    Public Structure CMDlineDBstruct
        Public Value As String
        Public StartPos As Integer
        Public EndPos As Integer
    End Structure

    Public CMDlineDB(100) As CMDlineDBstruct
End Module



' The following does *not* work

Public Class CmdParser
    Public Sub RemoveChrFromCMDlineDB(c As String)
        For i As Integer = 1 To CMDlineCount
            Replace(CMDlineDB(i).Value, c, "")
        Next
    End Sub
End Class


' Where-as the following works
Public Class CmdParser
    Public Sub t(c As String)
        For i As Integer = 1 To CMDlineCount
            For k As Integer = 1 To Len(CMDlineDB(i).Value)
                If Mid(CMDlineDB(i).Value, k, 1) = c Then CMDlineDB(i).Value = Left(CMDlineDB(i).Value, k - 1) & Mid(CMDlineDB(i).Value, k + 1)
            Next k
        Next i
    End Sub
End Class

Did you read the documentation for Replace?

"Returns a new string ..."

You are correct and it now works. That's annoying .
Just to explain: I honestly tried that at the beginning and it didn't seem to work, but there was probably something else wrong with the calling routine and I wasn't thorough enough at the time.
Also, there is a version of Replace which works in the way I was trying in VBA so I wonder if I saw that at some point.

Anyway, thanks for the pointer. I feel a tad silly. .

There is the .Net String.Replace function, and also the legacy Replace function...
