NAV 2009 RTC-Enum,DateTime,Currency datatype access frm .NET

Hi All,

NAV 2009 RTC is throwing error message when trying to access the following automation data type variables.

1. Enum
2. DateTime
3. Currency

These data type variables places a major part in our dll methods.

Following are the errors that NAV 2009 RTC showing up.

This message is for C/AL programmers: The call to member 'enumType' (Enum) failed: Method ‘Service.GetMethod.enumType’ not found Where enumType is of type Enum (Unmanaged)

This message is for C/AL programmers: The call to member 'dtDate' failed: Method ‘Service.GetMethod.dtDate’ not found Where dtDate is of type DateTime (Unmanaged)

This message is for C/AL programmers: The call to member 'Amount' failed: Method ‘Service.GetMethod.Amount’ not found Where Amount is of type Currency (Unmanaged)

I am not getting any error message with NAV 2009 Classic Version.

I have gone through forums and the experts are advising to change the data types in the dll since NAV 2009 RTC supports only managed code. But our dll which acts as a bridge between our service and our Navision 2009 RTC and we cannot change our Dll.

Please guide to overcome this issue and provide a valuable solution.

Thanks and Regards,
