Hi this is an example of doing strings in VB to split and join strings, I know there is aready functions to do this, but i wanted to have a go at makeing my own, anyway hope they be usfull

Place the code below into the general part of your form

Code:
Function vJoin(ByVal SourceArray, JoinChar As String) As String
Dim Count As Long
Dim Buff As String

    Do While (Count < UBound(SourceArray))
        'Build the string
        Buff = Buff & SourceArray(Count) & JoinChar
        'Inc count
        Count = (Count + 1)
    Loop
    
    'Remove last JoinChar
    Buff = Left$(Buff, Len(Buff) - 1)
    
    vJoin = Buff
    'Clear up time
    Buff = vbNullString
End Function

Function vSplit(ByVal Expression As String, Optional SplitChar As String = ",") As Variant
Dim Pos As Long
Dim Count As Long
Dim Inc As Long
Dim Temp() As String

    Count = 1
    
    Do While (Count < Len(Expression))
        'Find the position of SplitChar within Expression
        Pos = InStr(Count, Expression, SplitChar, vbTextCompare)
        'If we are at zero set pos to the length of the string + 1 to make sure we get the last string
        If (Pos = 0) Then Pos = Len(Expression) + 1
        'Resize array to hold strings
        ReDim Preserve Temp(Inc) As String
        'Store strings into array
        Temp(Inc) = Mid$(Expression, Count, Pos - Count)
        'Inc array counter
        Inc = (Inc + 1)
        'Inc counter
        Count = Pos + Len(SplitChar)
    Loop
    'Return split strings
    vSplit = Temp
End Function
Example place a new command button on the form and add the code below:

Code:
Dim Test() As String
Dim X As Long

    'Example
    Test = vSplit("Software,Games,Hardware,Split,Test", ",")
    
    'Show split strings
    For X = 0 To UBound(Test)
        MsgBox Test(X)
    Next X
    
    'Rejoin the array and show result
    MsgBox vJoin(Test, ",")
