1. Hello All!
Hello All!
I've been one of those "eavesdroppers" on the list for quite a while, and
after great angst concerning my inability to speak to large crowds, I'm going
for it! My participation may be little spotty, as I'm in the process of
moving to Amarillo, Texas, but I'll join whenever I can.
As far as where my programming knowledge base lies ... well, you are reading
the words of a time traveler! I've been away from computers for about 10
years, and while I've done a lot of catching up, I'm still way back there,
especially when it comes to windows. And I must say that you folks have been
responsible for much of the "getting modern" I have done over that past four
or five months.
One small comment I would like to make, for what it's worth. There has been
some dissension as of late about the "fights" that happen on the list, and
indeed about folks slamming Euphoria on a Euphoria mailing list. I suggest
that these "fights" are probably the best thing that can happen for Euphoria,
because it provides proof that the language is growing. It may be getting
stretch marks here and there, and Mr. Craig may not want his favorite son to
grow up too fast, but it is growing nevertheless. Take for instance this
argument about "namespaces." Now then, to prove my backwaterness, I must
confess that I have no clue what a "namespace" is, other than the little box
on the sticker that reads "My name is ..." But the carrying on about
namespaces has assured, even if it is not currently evident, that namespaces
will be addressed at some point in the future, and dealt with as the majority
demands. I would hope that such discussion, even if it does get momentarily
bitter, is never shunned, because that would be very detrimental to
Euphoria's cause. And, to be completely honest, much of what I've learned
about the programming world of 2000 I've gleaned from the information shot
around in such "heated discussions."
Soon I'll be going to school to re-learn the art of programming, and I hope
that Euphoria will be mainstreamed by then, yet not lose those
characteristics which make it such an incredibly useful language, especially
for time-warped types such as yours truly.
Alright, there's my blurb. Currently I am working on two projects: a
database for a homeless shelter here in town, as well as an IDE for Euphoria,
a monumental task to say the least. The IDE has taken the back burner here
for a bit, as I need to get the database finished before I leave, as a gift
to the shelter's manager for the help they gave me a few years back.
My question is: when printing from an MLE using Mr. Cuny's win32lib.ew, what
should I end each "string" with in order to get the printer to perform a line
feed? I've tried several combinations of \r\n, but without success. I have
e-mailed Mr. Cuny; however, because my Internet skills are very shaky, that
letter may have ended up with a Mr. Cuny in Paraguay! I am using an IBM
Proprinter II at the moment. If one of you fine ladies and gentlemen could
answer this infantile question for me, it would truly be appreciated.
Finally, since my machine isn't technically "hooked up" to the Internet, I
must use the facilities at the public library. Therefore, my responses may
take a day or two, but rest assured I will write back.
Once again, thank you all for aiding in my education. I look forward to
participating as much as my knowledge will allow.
God Bless and Blessed Be,

No, that's the wrong approach. Imagine that the printer is a bitmap: you
have to position the string on the page at a specific location. Take a look
at how GENERIC.EXW works. The untested code I've hacked together should give
you some idea how it works.
Hope this helps!

3. Hello All!
Hello All!
I am working on a Euphoria IDE and I was
wondering if I could get your help with a couple
of menial problems.
The first involves printing to the printer using
win32lib.ew. I have an older dot-matrix printer
(IBM Proprinter II). The goal is to get the
information out of an MleEdit and sent it to this
printer. When I try this using wPuts(), the
printer appears to "misinterpret" the \r\n
and "prints" them as small rectangular boxes. I
have tried quite a few combinations of \r and/or
\n, and none of them seem to work, yet the
printer works just fine with say, Microsoft Word,
for instance. Any ideas? This is driving me up
the wall ...
The second question involves the maximum capacity
of the MleEdit. From some of the literature I've
read, I got the impression that the MleEdit's
max. capacity was 32k. However, I'm having
problems with the Mle in my program when it gets
to 29k. This is how I'm calculating the size of
what's in the Mle in k:
AmountK = floor(length(getText(mleTextEditor)) /
1024)
Using this formula, the MleEdit appears to "lock
up" around 29k, at which point it will not allow
you to put in any additional information. Is the
math wrong? What is the capacity of an Mle in
bytes?
Thank you,
Travis Beaty

Take a look at GENERIC.EXW; it does exactly what you are describing.

The character you are getting is a 'nonexistant in font' character. The
process of printing on a printer is the same as printing text into a window.
You can't use \n or \r; you have to format the text yourself. That means:
- breaking the text into '\n' delimited paragraphs
- removing the non-printing '\n' characters
- breaking the paragraphs into page-wide lines
- placing the lines on the page
Obviously, you need to know the size of the page and the size of the font to
determine how much text can fit on a page.
You can use getSize() to determine the size of the page.
If you are using a fixed width font, you can use getFontSize to find the
width and height of the font. If you are using a variable width font, you'll
have to use getTextExtent to find the width of a string. In that case, it
might be cheapest to build a lookup table of the character widths.

I was under the impression that the maximum is 32K, but I can't confirm it.
If you are empirically measuring 29K, you must be right.
Hope this helps!

Hello, Travis.
I think the only way to bypass this barier is to use RichEdit32.dll
instead of
MleEdit !
I'm working to on a Source editor for Euphoria, but i've choosen to
build it
with another langage: witch compile and make little executables !
It's < 64K for now, and does some good things i think.
You can have more explanations on it into the archived ML of this
month. A new text editor...
see you !

The 32k limit, if I recall correctly, includes the line terminator characters,
which accounts for the perceived discrepancy.
7. Re: Hello All!
...sorry about the repeat, folks, but since it came up...again.
Anyone lamenting the 32k. limits of MLE's in win32 should look up:
limiting user-entered text, and
em_setlimittext
in win32.hlp
....it seems that a simple message can, at least, double this to 64k.
[ ...untested win32lib example ]
constant
EM_SETLIMITTEXT=197
integer junk
Haven't tried it, but....if it works
