Re: J# equivalent of C#'s 'typedef' and 'struct' keyword.

#1

Pushpendra,

MIDL supports typedef, C/C++ supports typedef, but as far as I know C# does
not support typedef. You may want to try using the preprocessor. For
example: #define unsigned_int System.UInt32.

Or you may directly use the J# equivalent data type for that typedef. For
example System.UInt32 l_unsigned_int;

If you mean typeof then you can use .class.ToType(). For example
myobject.class.ToType().

For structs use the StructLayout attribute and create a class. Here is an
example of the Win32 API SYSTEMTIME structure in J#:

/** @attribute StructLayout(LayoutKind.Sequential) */
public class SystemTime
{
public System.UInt16 wYear;
public System.UInt16 wMonth;
public System.UInt16 wDayOfWeek;
public System.UInt16 wDay;
public System.UInt16 wHour;
public System.UInt16 wMinute;
public System.UInt16 wSecond;
public System.UInt16 wMiliseconds;
}

Have fun,

Manny

Hi,
Are there any equivalent keywords in J# for C#'s 'typedef' and 'struct' ?

Thanks,

The J# and C# preprocessor does not support this style of #define (they
don't support any form of macro).
So, this won't work!

You can define structs(i.e., Value Types in .net) in J# from Visual
Studio.NET 2005 (Whidbey) onwards as below

public final class Address extends System.ValueType {
public static final String StreetNo = null;
//
public static final String Zip = null;
}

te that you will not be able to do the same in Visual Studio .NET 2002/2003
Current Visual Studio .NET 2005 is in Beta1 and you can install the
corrosponding .Net Framework Version 2.0 Beta1 from
http://www.microsoft.com/downloads/d...595-717C-4EF7-
817B-BDEFD6947019&displaylang=en
ad J# Redist 2.0 Beta1 from
http://www.microsoft.com/downloads/d...3f3-9eaf-4d41-
bad3-9f44fe8e5e81&displaylang=en
