Question

Basically what I am trying to do is to imitate the replace button with VBA code. I use the following code:

Private Sub CommandButton1_Click()
    Blad1.Activate
    Blad1.Cells.Select
    Selection.Replace What:=".", Replacement:=",", LookAt:=xlPart, _
        SearchOrder:=xlByRows, MatchCase:=False, SearchFormat:=False, _
        ReplaceFormat:=False
End Sub

This replaces all of the dots, but in some cases it replaces the dots with whitespaces instead of commas. Why is this?

Try this

Sub Sample()
    Dim oRange As Range, aCell As Range, bCell As Range
    Dim ws As Worksheet
    Dim ExitLoop As Boolean
    Dim SearchString As String, FoundAt As String
    On Error GoTo Err
    Set ws = Blad1
    Set oRange = ws.Cells

    oRange.NumberFormat = "@"

    SearchString = "."
    Set aCell = oRange.Find(What:=SearchString, LookIn:=xlValues, _
                LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
                MatchCase:=False, SearchFormat:=False)
    If Not aCell Is Nothing Then
        Set bCell = aCell
        Do While InStr(1, aCell.Formula, ".") > 0
            aCell.Formula = Replace(aCell.Formula, ".", ",")
        Loop
        Do While ExitLoop = False
            Set aCell = oRange.FindNext(After:=aCell)

            If Not aCell Is Nothing Then
                If aCell.Address = bCell.Address Then Exit Do
                Do While InStr(1, aCell.Formula, ".") > 0
                    aCell.Formula = Replace(aCell.Formula, ".", ",")
                Loop
            Else
                ExitLoop = True
            End If
        Loop
    End If
    Exit Sub
Err:
    MsgBox Err.Description
End Sub
