Hello all, some newbie questions, if that's ok:
I'm making a program by "grafting" some existing programs ("hecnor"s
multiplication table exerciser from the archive, & the "list with a twist"
example program from the Win32 Tutorial by Ad Rienks & Wolfgang Fritz), & I
have some questions I hope someone can help me with.
1. "hecnor"s program is copyrighted, so how do I go about trying to get his
permission to alter it & let people use it & offer it to the archive?
(There's no email address accompanying the program.)
2. I ran into a weird bug(?) with the graft of "list with a twist", namely
that a click on one control caused the effect of a click on another. The
multiplication exerciser has 4 buttons with possible answers to a
multiplication problem, and the list box has "ones" through "twelves" in
it, set up to set one of the multipliers. The problem arose when I made
that connection be "immediate" upon selection of the multiplier from the
list; what happened then was that when the user selected the RIGHT answer,
a new problem was immediately generated (when it should NOT be), which
usually made that previous "right" choice now WRONG. I could see no way at
all that it was being caused by mal-programming on my part, & was about to
ask you all here if you could figure out what was going wrong, when I
looked more closely at what was HAPPENING, rather than looking at the code,
& I noticed that when I clicked on the ANSWER button, the SELECTED item in
the list box "blinked" briefly; now if I HAD clicked on an item on the
list, that WOULD have generated a new multiplication problem, but I HADN'T,
I had clicked on the ANSWER button. It was as if the program "thought" I
had clicked in the list when I hadn't. So I inserted a "setFocus" command
to another button, to take focus away from the list box, & that solved the
problem. But my extremely limited knowledge about programming for windows
leads me to think it shouldn't have really happened like that in the first
place, since other controls, specifically the answer buttons, were utilized
by the program AFTER list box item selection by the user. Is this
"control cross-coupling" a normal thing to be regularly addressed by the
programmer, or is it some kind of bug?
3. And, a more general question/problem: I have my Win98 system set up to
display BIG TEXT & ICONS, and almost every program I have looked at in
Euphoria for windows has had problems on my system of not having enough
room on buttons & other controls to show all the text. I regularly correct
this, by making the values for the size of the controls bigger, but my
concern is that I have NEVER seen this problem in other programs (except
one: the toolbar in windows explorer doesn't show everything), & I suspect
that controls I make "ok" for my system may look way too big for their text
on OTHER systems. I remember someone here on this list saying something
once about "if it's allowed by windows, it should be handled correctly by
Euphoria", or something like that, so I wonder if this isn't an instance of
that? I've noticed the problem in both Win32Lib and VEL.
Thanks,
Dan Moyer
