VB6 string replace

So I have an issue that I cannot figure out.

I have a string that contains email addresses

I.E
test@test.com, test@123.com, test@456.com

Open in new window


I have another string set of
 I.E
test@123.com, test@test.com

Open in new window


I want to remove the second string set from string 1. Even though they are not in order.  I don't know how to figure this one out.  I would assume that i need to separate the second string into an array perhaps and do a foreach loop which removes them from string one.

Scratching my head at this moment.

what about:
Dim s1 as String 
Dim s2 as String 
s1 =  "test@test.com, test@123.com, test@456.com"
s2 = "test@123.com, test@test.com"

Dim arr() As String = Split(s2, ",")
Dim i as Long
s1 = replace(s1, " ", "")
i = lbound(arr)
while i <= ubound(arr)
begin
   s1 = replace(s1, arr(i) & ",", "")
   i = i + 1
end

This may help.

Sub Remove()

    Const delimiter As String = ","

    Dim iterStr As Variant
    Dim mainlist As String
    Dim sublist As String
    Dim split_sublist() As String

    mainlist = "test@test.com, test@123.com, test@456.com"
    sublist = "test@123.com, test@test.com"
    
    split_sublist = Split(sublist, delimiter)
    
    For Each iterStr In split_sublist

        'clean iterStr the way you want.
        iterStr = Replace(iterStr, " ", "")

        mainlist = Replace(mainlist, iterStr & delimiter, "")
        mainlist = Replace(mainlist, iterStr, "")

    Next iterStr
    
    'clean mainlist the way you want.
    mainlist = Trim(mainlist)

End Sub

For Hakan, I get a Mismatch on the FOr each line

For Guy -

I dont see where this outputs to a string. Only an array.

Can you please write me what error is? I don't have vb6 installed. I try it in excel VBA.
Also please change "Dim iterStr As Variant" to "Dim iterStr" and try.

So the whole error is Error: 10080 (10080) Type Mismatch Line number 17. This is also after I have changed the dimension.

It is on the "For Each" line of code.
Hakan YılmazProject EngineerCommented:
Can you please now change it to "Dim iterStr As String" and try?
desiredforsomeAuthor Commented:
I get Error 0 Var is already defined as a different type line 17 (that is on the For Each line)
Hakan YılmazProject EngineerCommented:
Please try this.

Sub Remove()

    Const delimiter As String = ","

    Dim mainlist As String
    Dim sublist As String
    Dim split_sublist() As String

    mainlist = "test@test.com, test@123.com, test@456.com"
    sublist = "test@123.com, test@test.com"
    
    split_sublist = Split(sublist, delimiter)
    
    For Each iterStr as String In split_sublist

        'clean iterStr the way you want.
        iterStr = Replace(iterStr, " ", "")

Error 0
Expeting 'In' line number 16   (Same line as always). I am try to figure this out with research and and pulling hair out.
Hakan YılmazProject EngineerCommented:
VBA and VB are very similiar, i have mixed syntax.

Changed code to loop between bounds. Please try this.

Sub Remove()

    Const delimiter As String = ","

    Dim i As Integer
    Dim iterStr As String
    Dim mainlist As String
    Dim sublist As String
    Dim split_sublist() As String

    mainlist = "test@test.com, test@123.com, test@456.com"
    sublist = "test@123.com, test@test.com"
    
    split_sublist = Split(sublist, delimiter)
    
    For i = LBound(split_sublist) To UBound(split_sublist)

        iterStr = split_sublist(i)

        'clean iterStr the way you want.
        iterStr = Replace(iterStr, " ", "")

        mainlist = Replace(mainlist, iterStr & delimiter, "")
        mainlist = Replace(mainlist, iterStr, "")

    Next i
    
    'clean mainlist the way you want.
    mainlist = Trim(mainlist)

End Sub
