eFistAnt, LOL Why in group "View"? :)

That's one of the groups, I'm 'monitoring'. You made me look, so 
now you earn me a beer in Italy! ;-P

I was trying to extend iterated faces example from http://www.rebol.com/docs/view-system.html#section-10
to support feel/over but with I was not very succesful. Iterated 
faces react on over (I'm changing color of edge) but when I click 
on one of the faces, now all other iterated faces' edges use the 
"over" color. Can anybody help me?

What is a good way to check for certain values in an input field?

Let's say, I want to do an integer field, I've tried this as the 
action function:

if error? try [to-integer value] [set-face face 0]


It works first time, but if I try enter an integer afterwards, it 
just get settet to zero again. Any ideas?

maybe "0"? if you dump the later errors, it should say something 
like "cant append to an integer" your way".

No, doesn't work setting it to "0". Try this:

view layout [field "0" [if error? try [to-integer value] [set-face 
face "0"]]]

You can enter integers at first, but if you enter a letter, it stops 
working.

I had the same problem and did not find a solution

You can note something to rambo:

view layout [field "0" [probe face/text probe value if error? err: 
try [to-integer value] [probe disarm err set-face face "0"]]]

the face/text contains the new value, but 'value itself stays on 
the buggy one.

so this works:

view layout [field "0" [if error? err: try [probe to-integer face/text] 
[set-face face "0"]]]

because ctx-text/edit-text uses /data, not /text.
not updated because of error.
                if flag-face? face return [
                    if flag-face? face hide swap-text 

                    if flag-face? face tabbed [focus next-field face] 
                    action face face/data 
                    exit
                ]

so setting /data by hand works too:

view layout [field "0" [probe face/text if error? err: try [to-integer 
value] [probe disarm err set-face face "0"]]]

pasted wrong version

view layout [field "0" [if error? try [ probe to-integer value] [set-face 
face "0" face/data: face/text ]]]

Thanks Volker!

(dont forget to met rambo ;)

Sent it to RAMBO.

Kru, you need to maintain external state data just like the SELECTED 
index in the example.
Here are my diffs from the original example:

over-index: 0

	;edge: none

		over: func [face action position][
			print ["Over" action]
			over-index: all [action face/data]
			show main-face
		]

			aface/edge/color: either over-index = index [sky][coal]

Can someone point me to the syntax for radio-line?  and check-line?

Mike, a bit here: http://home.tiscali.dk/john.niclasen/vid-styles.html#section-5
If you do e.g.: 
layout [mycheck: radio-check "something"]

then mycheck/data will be true or false. Is that, what you needed?

view layout [radio-line "one" radio-line "two" radio-line "a" with 
[related: 'my-alphabet-radios] radio-line "b" with [relate
d: 'my-alphabet-radios]]

Thanks Anton and John.

Shorthand for "with [related: 'group]" -- radio-line "one" of 'group

Anybody here with already done notes on text-list internals (lc, 
sn, cnt...) ???

Is it possible in the VID style "key" to check, if SHIFT is pressed 
too?

sorry, lol confusing

I want to check, if e.g. '1' is pressed on the numeric keyboard together 
with SHIFT.

hmm it's probably not, because those keys then send HOME, END, and 
so on.

I put a VID screen on some mySQL data (using the Doc's protocol) 
and allowed paging through it using the left and right arrows. Worked 
fine for a small database; very fast refresh of the page. 

When I used the same approach on a larger DB with some TEXT fields, 
it started to hang at the same record when going '"right".   


After much trial and error and guessing, I think it is because the 
database is not quite fast enough to refresh the screen to keep up 
with holding the key down.   


I put it sub-second wait in before the screen reshows its values 
and the problem went away.   	ie wait 00:00:00.005   


I don't think it is a database problem because it could happen with 
slower devices such as files. 


Is this consistent with what others have seen or am I 'fixing' the 
wrong problem?

hmm, I would like to know Mike, what actually were you doing? Because 
- in old DBF x-Base days it worked like that - you simply had "cursor" 
at some db position and you moved by using 'skip command .... of 
course even then, it was wise to use indices and to limit the scope 
of data you work with ...

now SQLs are different kind of beasts -  there is NO live connection 
to sql database (on cursors later :-), you simply send a query, SQL 
server prepares results for you and sends it back to you. So, I wonder, 
how could actually SQL server slow your recordset browsing? And IF 
you were sending new requests after a key-press and wanted to stay 
real-time, then it is quite heroic aproach :-) Within our SAP system, 
you are glad if you receive your query result in few secs.

So, mostly, if you work with SQL, you try to find the right context 
of data, limiting your query as much as possible. Then you do a query, 
receive result and browse it. In that case, you already have all 
your data in rebol block already (unless you are reading them from 
port continuously), and it has nothing to do with SQL database anymore 
...

Now on cursors - of course, old x-base aproach is possible with SQL 
too, it is called "live cursor" or something like that. But with 
larger systems, adming don't allow or don't like to see it, as it 
consumes additional resources. Some of databases even don't have 
it. IIRC mySQL will introduce it from version 5.0, or maybe I am 
wrong ....

Not using a cursor. Right key action  increments current-record-key. 
Retrieves single row for current-record-key, Displays page with data 
for row retrieved.  The database is local and only has (so far) 120 
rows but I have another with three hundred shorter records (no BLOBs) 
on it and it works well without any wait.  i.e. I can hold down the 
right key and it will flash each page by.  MySQL protocol has always 
seemed very fast to me.  Is it possible that View is stacking up 
the key actions and hanging after it gets too many?  p.s. I don't 
want to read the whole database content into memory because then 
I have to worry about locking when I allow HTML updates to it by 
others.  Single row updates with the last update 'winning' in the 
unlikely event of a collision works well for what I need to do.

Hello, anyone have any ideas how I might improve on the integrity 
of a program that sends email to a list of people. I just realized 
I should be using '/only' but I have to check its behavior as I don't 
want each person to get a list of the other recipients. My problem 
is I often get a time out and I want to trap that. Yesterday during 
my first test it got halfway through the list and errored out which 
then caused the program to exit. I figured I should at least keep 
a running log so I can go back.

Again, I check but I wonder how the header will behave with an '/only' 
Will the "to:" address be altered?

I guess it has to be a generic address in the header. It doesn't 
change it. Oh, well, that'll work as well.
