Hi to everyone,

I am testing Euphoria for use in a pet project of mine and I need
runtime created, movable, sizable controls.

I am working from mousetrap.exw (in \Win32Lib\Demo ) which just does that.

Wherever I insert the follwing code I just can't get a runtime control to show
up  :

myControl = create( Button, "Close", 0, 5,125 ,300, 25,{WS_CHILD, WS_VISIBLE})

Thanks for your guidance,

Arb

I don't think you had to use that function. You could try:

myControl = create( Button, "Close", 0, 5,125 ,300, 25, 0) -- Taken flags out

The flags you tried to define are already defined by the library and you were
replacing
the flag that made it a button - BS_PUSHBUTTON. Read the documentation for
create(), in
win32lib/docs. Look at flags, then read the docs for PushButton.

This is my understanding, so someone may argue with me, but see if it works!

I prefer Dave Cuny's EE or Carl R. White's EE:CS.  There are others, and I
think there are one or two visual IDEs for Windows programming, but I haven't
used them yet.

Euphoria doesn't force OOP on you, but if you like OOP, there are several
different libraries available that implement it.  They vary in complexity,
style, size, and speed, so you can choose the one most suited to your needs.

In most cases, pointers aren't needed.  When they are, you can allocate
memory,  get a pointer to it, and do whatever you want with it using peek()
and poke().  You can't get pointers to variables declared normally, though.

As for routine pointers, you can get a routine_id, an integer which can be
used to call the routine.  It's not an actual physical memory address, but it
can be used to implement forward-referencing, mutual recursion, and
polymorphism.  If you really need a pointer to the machine code of a routine,
(for low-level speed-critical things, maybe) you can write the routine in
machine code, allocate memory for it, poke it, and call it.

Most libraries are made available in source-code form, so you can study them,
modify them, etc.  (And deal with namespace issues)  If you want to, you can
shroud them into a binary form and they can still be used but not easily read
or modified by others.  Of course, you can also use DLLs in Windows.

You're living dangerously. Those programmers are likely to
react badly to any criticism of their language of choice
(a.k.a. Job Security)

I wrote my first for-money program in BASIC, about 20 years
ago, a program to manage materials flow for a recycling firm.
I also realised I had reached the limits of BASIC - let's call
it the "brick wall". That's when it becomes almost impossible
to add even one more thing to your program without it
blowing up permanently. Or, in the case of BASIC, runs
so slowly no one wants to use it.

As soon as Borland began selling Turbo Pascal, with many
useful features, I moved to that, then COBOL (job requirement),
and more recently Delphi and others. All of these languages
have their own "brick wall", some just hit it sooner than others.
Euphoria is no exception; but it is a *huge* improvement over
BASIC, and way simpler than C.

If you don't know BASIC very well, you will have an easier
time learning Euphoria. Not so many bad practices to unlearn.
If you know C, Euphoria looks familiar, but with lots less
"dirty work" to do (type casting and pointer manipulation)
If you know Pascal, Euphoria looks very familiar, but
again, there's less type casting required.

If you're just starting, Euphoria will help you learn to write programs in a
"structured" manner - always a good thing.

Yes, they could easily learn Euphoria. In fact, it might be
useful for lots of little jobs - mainly because it is MUCH
less likely to cause "unexpected results" than C/C++

Could be. Robert?

VB is very different from QBASIC. In many ways it reminds
me of Pascal/Delphi. It's good to learn VB, you can get some
jobs writing VB pgms.
