[REBOL] Re: The all function.
No, adding copy didn't fix your code. Removing the 2 did. (Although, I am not really sure it is fixed...) The problem is that find takes two arguments, not three, as you seem to think in this line: find database 2 chknum This just returns the value of chknum. You had obviously set chknum sometime in your testing on the console. I'll put brackets to show how the above line was evaluated: (find database 2) (chknum) The first value returns none, the second value returns "9898", which must have been what you set it to at some point. In the 'all block, you actually had three values to check, not two, as I am sure you thought you had: rec: all [find database code find database 2 chknum] I will put brackets to show how it was evaluated. rec: all [(find database code) (find database 2) chknum] So 'all would have returned at the second value (none). Perhaps you meant to write: find database/2 chknum That means to look in the second value of the hash!

[REBOL] Re: Iterated check box anomaly
Hi Geza,
List & supply is just a VID interface to face iteration in View. ("supply"
is akin to a "pane func" with a little less effort needed)
If you would like to dig further in iterated faces, the following Zine
article may help.
"Look ma, just one face"

[REBOL] Re: Iterated check box anomaly
Hello Romano, > you must re-initialize the check data field: > if index = 1 [face/data: find a face/text] Hmmm, tricky ;-) Thank you very much, it is a great idea! BTW What is the exact timing of the 'supply function, i.e. on what occasion (event) will it be launched? As far as I can see, it is called not only at initialization time (filling the list with items) but even when I click in the list? First I tried toggles instead of check boxes, but selecting one of them caused to redraw all toggles below the selected one in selected state :-( Is there a way - via some kind of reinitialization - to use toggles properly in an iterated list? Again, View docs are euphemically sparse on a quite difficult topic, like face iteration. -- Best regards, Gezamailto:[EMAIL PROTECTED] -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with "unsubscribe" in the subject, without the quotes.

{Maybe today is one of those days when we need to build a new REBOL version.

single click of my mouse, fires up the "build farm" and compiles, links,

Hello Alan, Here is a quite simple simple solution: rebol [] m-l-c: [ ["from1" "subject1" "contents1"] ["from2" "subject2" "contents2"] ["from3" "subject3" "contents3"] ] view layout [ below list 550x180 [ btn: button [probe reform [btn/text fld1/text fld2/text]] fld1: field fld2: field ] supply [ if count > length? m-l-c [face/show?: false exit] face/show?: true face/text: m-l-c/:count/:index ] ] Points to keep in mind when designing an iterated list: - harmonize the overall list size and the sizes of the individual items in the list - 'count holds the iterated row number - 'index holds the face index in the row (in the above example, as faces appear in the layout they are linked to the data consecutively: 'btn = 1, 'fld1 = 2, 'fld2 = 3 - faces WILL be iterated to the total height of the list - in the 'supply block setting the face/show? to 'false is _vital_ to hide obsolete extra (repeating the list row!) elements; in this algorithm "overflow" of the iteration is prohibited by the 'if control structure.

[REBOL] Iterated check box anomaly
Hello REBOLers! I have a question upon a strange behavior of an iterated check box. The list contains a checkbox and an explanatory text per row. Here is the code snippet: a: copy [] q: [ ["1" "Setup"] ["2" "Install"] ["3" "Post-install"] ["4" "Run"] ] view layout [ below list 550x180 [ across origin 2x2 answer: check [ probe a: either probe answer/data [ sort unique append a answer/text ][ sort difference a compose [(answer/text)] ] show answer ] question: info wrap 500 ] supply [ if count > length? q [face/show?: false exit] face/show?: true face/text: q/:count/:index ] ] If I, e.g. select the first answer, then the check box redraws appropriately; thereafter if I select the second answer too, the check box remains in "false" state after the first click - only the second mouse click toggles it's state to "true". Probing the state of the checkbox and the list of answers reveals that the first click on the check box does not toggle it's state IF the previous selection (on another check box) resulted in the same state. I.e. YES-YES or NO-NO answers on two different checkboxes do not toggle the state of the second one, only alternating selections (YES-NO). Despite the visual fault, the action code executes properly and updates the answer block: true ["1"] false ["1" "2"] true ["1" "2"] This is strange: the checkboxes appear to behave as if they were ONE, if they were the SAME face visually but the branching upon their individual logical state executes normally and fills the answer block appropriately. Is there a way to overcome this in an iterated list or should I accept that sometimes two clicks are needed to toggle the "visual" state of a checkbox?

That line really should read

although the space isn't mandatory because of the opening
brace for the string. Getting in the habit of inserting
spaces will:
- make your code easier to read
- keep your fingers from leaving out non-optional spaces

[REBOL] Re: Retrieving mysql columns by name
Thank you for answering my question.
Here's another one.
-
I wrote this program :
;; this is the list of columns in my Mysql request
zlistechamps: copy [ "livnum" "livtit" "livaut" "livcat" "livdif" "autnum"
"autabr" "autcom" ]
getcol: func [ prow 'pnom ]
; prow is the row i get from mysql request
; pnom is the name of the field i want to retrieve
[
use [ xind ]
[
xind: index? find zlistechamps pnom
pick prow xind
]
]
I then get my values by :
print getcol row "livnum"
print getcol row "livtit"
print getcol row "autcom"
which is equivalent to
print row/1
print row/2
print row/8
This way seems to me much more easy and self-explaining than using order
numbers. It has the advantage to be request independent.
Last problem to solve : How can i automatically create the list of fields in
zlistechamps; can i retrieve the columns names from mysql, in a manner like
"show columns from table". The difference is that the sql request is not
upon a table but is a join request.
Further, I think the ultimate goal would be object oriented programming,
something that could look like this :
rq: open_request("select .")
rq/next
x: rq/fields "livnum"
...
It's just an idea from a newbie in Rebol (i don't even know if the syntax is
correct); perhaps does this already exist ?
Thank you.

How? "if necessary" based on what? Do you mean some sort of
syntax-driven recognition/parsing?
As for the rest, let's pretend that "a function name" is the
letter #"F" followed by one or more digits.
Here's some sample data:
8<--begin morelines.txt--
blah blah F123 blah blah blah F45 blah blah
yadda yadda F678 yadda yadda F123 yadda F678
bloop bloop bloop F bloop
tada tada tada tada
dum da dum dum F123 F9 dum da dum dum
8<--morelines.txt ended--
and here's the script that does what you described:
8<--begin morelines.r--
REBOL []
morelines: make object! [
names: []
digits:charset "0123456789"
fnamerule: [#"F" some digits]
run: func [fi [file!] fo [file!]] [
names: copy []
foreach line read/lines fi [
parse/all line [
any [
copy name fnamerule (
if not found? find names name [
append names name
]
)
|
skip
]
]
]
write/lines fo sort unique names
]
]
8<--morelines.r ended--
after saying this at the console:
>> morelines/run %morelines.txt %morelines2.txt
we have
8<--begin morelines2.txt--
F123
F45
F678
F9

[REBOL] Re: Shortage of network connections
A few weeks ago I complained about problems with unsuccessful tcp/ip connections. I said, I will check this problem in greater details at the other side too. After gaining access to the host I could see, that it was mainly a problem with Rebol alone. Therefore I wrote a client test program, that does nothing but opening a socket, transfers some bytes, reads some bytes and closes the socket again. This approach done in a loop leads very soon to connection errors. But if I place a wait before the next opening, I can open, exchange messages and close the connections in abundance, even if I use "wait 0". Probably wait seems to clear or renew some conditions needed for successful tcp/ip connections under Win/NT. If I remember right, other members of the mailing list reported similar observations too. They just succeded after adding an otherwise useless wait 0. So what does "wait 0" and should the clearance of the network status not be part of the normal port handling?

[REBOL] Re: Core 2.6 - Last minute requests - take your chance! - shares
That would be cool. I think 'b would have to be a new datatype. One that stored its own index and length and imposed its head and tail on the series. But what happens when elements are removed from 'a that are also in 'b ? Should the length of 'b be reduced? Rebol would have to keep track of all the shares and update them when the original series is modified. This would slow rebol down a fair bit, I reckon. Otherwise, the length of 'b wouldn't be updated and you could get the situation where the length of 'b is greater than the number of elements that 'b shows! But that might just be a totally acceptable situation too! Maybe the user could be in charge of updating the length of the share when it seems appropriate.
