Thanks to Dick Kusleika for answering my question and to put me on the right track.

Here is the final solution for anybody having similar demands. It basically works with an ActiveX TextBox to enter the search-string. The macro than is looking in the search-area for all entries containing the search-string. All other filled rows within the search-field will get hidden. This works right away when writing into the TextBox. So, when deleting characters in the search-string the once hidden rows will appear right away if appropriate.

Private Sub TextBox1_Change()
 Dim searchArea As Range, searchRow As Range, searchCell As Range
 Dim searchString As String
 Dim lastRow As Integer

 Application.ScreenUpdating = False
 searchString = "*" & LCase(TextBox1.Value) & "*"

 ' unhide rows to have the full search field when editing
 Rows.Hidden = False

 lastRow = ActiveSheet.Cells(Rows.Count, 1).End(xlUp).Row
 Set searchArea = Me.Range("A5", "A" & lastRow) 'Me.Range("A5").End(xlDown))
 searchArea.EntireRow.Hidden = True

 For Each searchRow In searchArea.Rows
   For Each searchCell In searchRow.Cells
     If LCase(searchCell) Like searchString Then
       searchRow.Hidden = False
       Exit For
     End If
   Next searchCell
 Next searchRow

 Application.Goto Cells(1), True
 Application.ScreenUpdating = True

End Sub

works like a charm.

You can't. The code engine won't run while Excel is in Edit mode. You have to have the user enter the text in something other than a cell - like a control on the worksheet or a control on a userform.
