Another good book on Windows programming is
Win32 Programming by Brent Rector, published by
Addison Wesley USA
It is especially good at explaining introductory concepts.
I should know, I'm a beginner at windows too.
It also points out when the windows documentation is wrong
or lacking or misleading to save hours of heads smashing into walls.

Rick,

I think that ALL class-methods must have a special character to distinguish
then from Forth word. The ":" word would check this preliminary before
validate the method definition.

        : <Rectangle ...

        :M Rectangle: ... ( Yerk version )

Doing so in big development make sure we can always see the difference
between true Forth word, and class-methods.

About MFC Forth implementation, my opinion is that the API words are
sufficient. The following definitions are not really necessary:

        Class CDC
          ...
            : <Rectangle ( x y x' x' -- ret ) 2>R h -ROT 2R> Rectangle ;
          : <RectanglePtr ( pRect -- ) ... <Rectangle ;
          ...
      Class-End

But the following class definition help anybody:

        cWindow SubClass cListbox
        Public
            : <AddString ( zStr -- )
                LB_ADDSTRING 0 rot <SendMessage drop ;

            : <DeleteString ( index -- )
                LB_DELETESTRING swap 0 <SendMessage drop ;
            ...
        End-Class

MFC is a C++ work, mimic MFC in Forth is dangerous because exacerbate Forth
default (lack?).

But Forth and API can coexist without problem, we can use all the Forth
quality with API. ( NB: ['] postpone ... incompatible with class-method )

Subject: ofn and interpret

Sftalkers:

I am working on an application with a menuitem which opens the OpenFile
dialog. This is patterned very closely after the OFN INTERFACE in the
example LIFE.F.

In LIFE.F, the chosen file is then opened with OPEN-FILE and READ-LINE puts
a line at a time into PAD.

Rather than using READ-LINE, I would like to use INCLUDE-FILE to read *and
interpret* the contents of the chosen file. I cannot seem to to do this
using either the id and INCLUDE-FILE or the file name with INCLUDED. I can
open and read the file into a buffer, but when I try to interpret the file
using INCLUDE-FILE or INCLUDED, the data does not transfer and I get serious
error -9998.

I can run my read-and-interpret word from the console and it works fine, but
not from within the application. What is going on? Is there some reason I
cannot intrepret while running an application?

Subject: DLL's and Java Native Methods

I know that you can make DLL's from Swift Forth. However I want a Java program to call applications written in Forth and the Java documentation tells you how to import methods written in C++ or the like using their Java Native Interface (JNI). So I am wondering whether or not a Forth based DLL is the same thing as a importable native method for Java. If not exactly so, what should I do to make this work?

Thanks,
