Question : riddle vb.net calling unmanaged c++ dll

hi experts,

since our server moved to windows 2008 64 bit,our old delphi 5 cgi wont work anymore cause of iis incompabilities.

The delphi cgi prog uses a foreign c++ dll with unmanaged code.
The dll was introduced in delphi with:

1:

function AbgabePreis(p:pChar): pchar; cdecl; external 'customer.dll' name '?AbgabePreisBerechnung@APlusVServerDelphi@@YAPBDQBD@Z';

I now try to rewrite the application into a vb.net aspx solution.

<DllImport(DllFileName, _
            EntryPoint:="?AbgabePreisBerechnung@APlusVServerDelphi@@YAPBDQBD@Z", _
            SetLastError:=True, _
            CallingConvention:=CallingConvention.Cdecl, _
            CharSet:=CharSet.Ansi)> _
        Public Shared Function StrAbgabePreis( _
            ByRef s As StringBuilder) As StringBuilder
          End Function


I tried a lot of possible solutions but no avail.
The entry point is correct. The problem is that the dll is not getting the correct parameter.

Any help is much appreciated.
