Probleme mit ShellExecute

[Assarbad]

Warum nil und nicht 'open' als zweiter Parameter? I.e. als Verb.

Zitat:

NULL
In systems prior to Microsoft Windows 2000, the default verb is used if it is valid and available in the registry. If not, the "open" verb is used.

In Windows 2000 and later, the default verb is used if available. If not, the "open" verb is used. If neither verb is available, the system uses the first verb listed in the registry.
