    Hello,

    I would like to have the search string for the Objects.Names property. Is it possible to use the indirect operator ($$) to accomplish this?

    Example:
    Dim TransscriptNames = \Messdaten\.Objects(“^P1.*\.fld$”).Names

    give me the names of the folders starting with “P1”, which I would like to be variable, so I tried this:
    Dim SearchString = “^” : “P1” : “.*\\.fld$” //”^sig.*\.dat$”
    Dim TransscriptNames = \Messdaten\.Objects($SearchString$).Names

    but this results in a “Variable not declared” error.

    Syntax error or no can do?

    Regards,

    The Objects.Names property uses a string as select argument. This can be a constant string like “^P1.*\.FLD$” or a variable containing such a value.
    If for example someone wants to specify the folder by a varying number, a code fragment like

    
Dim no = 1
Dim select = "^P" : String no : ".*\.FLD$"
dim folderNames = \Messdaten\.Objects(select).Names

    lists all folders under the root folder Messdaten prefixed with ‘P’ and the number.
    If one uses names like “P001”, “P002”, … to distinguish between the different objects, the following expression constructs these strings from a numeric value:

    
Dim no = 1
Dim objName = "P" : StringMid(String (no + 1000), 1)
