[REBOL] AW: Core 2.6 - Last minute requests - take your chance!
Hi, Rebol/View has two functions, to-rebol-file and to-local-file. Quite useful when you write scripts that get filenames as arguments and are still to be platform independant. Would be nice to see them in Core, too. Ciao, Jean -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with unsubscribe in the subject, without the quotes.
[REBOL] load vs load-thru (vs load path-thru)
Hello,
I've come to an inconsistency, I think.
I reckon load-thru should return the same
results as load, and it doesn't.
site: http://anton.idatam.com.au/rebol/
== http://anton.idatam.com.au/rebol/
url: site/anim/images/iconDilbert.png
== http://anton.idatam.com.au/rebol/anim/images/iconDilbert.png
load url
== make image! [64x48 #{
0...
exists? path-thru url
== false ; not in the public cache
load-thru/update url
== PNG ; - why this? shouldn't it be an image! as above?
exists? path-thru url
== true ; now it is in the cache
load path-thru url ; ok, so I can get the data in the end...
== make image! [64x48 #{
0...

[REBOL] Problems with Dynamic Library Access in View/Pro
Hi Holger and all on the List,
I have a problem regarding accesing DLLs from View/Pro:
I have this C function(watch out line breaks!):
from .h definition file:
...//this is value needed for the first argument of the funciton
#define DCSDKVersion 0x0154
#else
...//this is the structure needed as a input argument for the function
typedef struct{
DCCameraType CamType;
DCCameraType SpecificCamType;
BOOL DriverOpenFlag;
BOOL CameraOpenFlag;
BOOL ROMModeFlag;
} DCDriver, FAR *DCDriverPtr;
...//this is the fuction definition
DCOpenDriver(
SHORT FAR * Version, // This should be passed as the constant
// DCSDKVersion
DCDriverPtr Driver // This is a system dependent structure that
// contains information about the open
// driver.
);
or simmilar stuff in Visual basic interface layer:
Public Const DCSDKVersion = H154
.
Type DCDriver
CamType As Long
SpecificCamType As Long
DriverOpenFlag As Boolean
CameraOpenFlag As Boolean
ROMModeFlag As Boolean
Reserved As Integer
End Type
.
Declare Function DCOpenDriver Lib DC120VBIFLV154_32.DLL Alias
_DCILVBOpenDriver@8 (Version As Integer, Driver As DCDriver) As Integer
So I did this in Rebol(this is for the VB layer but for the direct C dll
calls should be almost the same):
DC120vb.dll: load/library %DC120VBIFLV154_32.dll
DCSDKVersion: 340 ;154 hexadecimal
DCDriverPtr: [0 0 0 0 0]
DCDriver: make struct! [
CamType [integer!]
SpecificCamType [integer!]
DriverOpenFlag [integer!]
CameraOpenFlag [integer!]
ROMModeFlag [integer!]
Reserved [integer!]
] reduce DCDriverPtr
DCOpenDriver: make routine! [
version [integer!]
driver [
struct! [
CamType [integer!]
SpecificCamType [integer!]
DriverOpenFlag [integer!]
CameraOpenFlag [integer!]
ROMModeFlag [integer!]
Reserved [integer!]
]
]
return: [integer!]
] DC120vb.dll _DCILVBOpenDriver@8
but when trying:
probe DCOpenDriver DCSDKversion DCDriver
...Rebol crashes :-(
only when DCSDKVersion: 0 I got some strange number(which is different from
the error codes in the sdk) returned from the function.
The crash behavior is the same when I tried it using VB layer or dirctly
call the generc dll :((
Am I doing something wrong? It is a bug of Rebol? Anyone?
Regards
Cyphre

[REBOL] view/list: altering layout possible?
Hi, I have the following problem and don't know what's the best way to solve it: - I use a list that has three columns all of type text. - There are some actions attached to the text faces. Now I want to insert some rows into my list that use a different row layout. An image and a text. The problem is that the list style takes one 'layout block and this one can either be for the text rows or the image row. What know? I see the following possibilities (disadvantages marked with -, advantages marked with +) 1. I use one list style with a container like a box and use the box/pane to insert a single face I build a priori. + simple pattern for list style - need to simulate the 'supply thing of a list where all columns get triggered - need to create one layouted face that can be inserted into the pane - need to handle positioning and sizing myself 2. I use one list for the text rows and create single faces for the image rows. The image rows are than positioned as a layer over the list (at the position where a image row is placed, the text list will have an empty line) faking the one-list imagination. + simpler to programm - syncing list scrolling might be tedious 3. Use the following list layout: image text text text and decided within the 'supply function if an image is needed or not. If not I can hide the face (?) or set the size to 0x0. + consistent with list style - context depending code within gui code - tricky to understand What do you think about the three possibilities? Did I miss some other possibility? Robert -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with unsubscribe in the subject, without the quotes.
[REBOL] Rebsite Anton updated, new scripts
Ok, this is worth a post. I have just gone through and updated my rebsite to complete the move to my new site, and added lots of scripts that were missing. Here is where it starts: http://anton.idatam.com.au/rebol/index.r and you can navigate to it in the rebol desktop via Rebol.com/Sites/Anton Not everything you click on gives instant results, but there is plenty to click on all the same. I am expecting some of you will have some older files like: library/graphics.r library/dir-utils.r library/trigonometry.r That will cause a problem. If you reload these ones specifically, it should fix most problems. Of course, if something doesn't work, write an email and let me know.

[REBOL] Re: REBOL : Pure OOP project ?
Hi Chris, Considering the low number of replies I got from the list regarding this thread : Class object inheritance library interest ? and the interest shown in the Business object versionning thread. I begin to think that either Rebolers are not interested in almost pure OOP with REBOL or that interest is only limited to one's personal project... I thought, when I started with REBOL, that I would build an OOP infrastructure for my projects (as I had done in the past with other languages), but the more I've worked with it, the more I've moved away from that line of thinking. I'm still finding my way with REBOL, from a design and style perspective, so my view is hardly something to be taken as gospel. I know that Carl has professed that he is recovering from OOP and the design of REBOL shows this, while it's flexibility allows you to do OOP pretty darn well if you want. I can see building an extensive OOP system as a great challenge, and certainly possible, but I'm not sure the solution will be as elegant as it otherwise could be. Caveat emptor, I haven't built any large systems with REBOL, where OOP might really shine. I look forward to seeing your results if you pursue them. --Gregg -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with unsubscribe in the subject, without the quotes.
[REBOL] Re: REBOL : Pure OOP project ?
Hello Guys, I haven't been following this thread very closely: but here are my thoughts on the OOP approach: I'm designing a DB-based system to service a number of clients, each with a variety of needs. My hope is to service all of them with the same application, in which most of the custom code is re-evaluated global data, rather than code. It's been a bit of a headache to keep the side effects down. It seems that every time I make a change, I introduce an error. More of an OOP approach would make maintenance easier, I'm sure. My experience with Ansi C (large projects) has taught me that you can do OOP with any language, but it takes some thought and design. My experience with C++ (large projects) has taught me that poorly managed or designed OOP can be a major headache and cause overly-frequent recompiles. In a word, I'd like to keep a thread on OOP going. How can I contribute?

[REBOL] Re: REBOL : Pure OOP project ?
Hi, Forgot to say something about my current implementation ... The worst/best part is that it does not support function refinements ! I can understand the power of refinements, and have even used it for some small scripts... but at the same time I don't like it... I have found that most of the time, refinements are simply booleans with further arguements. Furthermore, they are usually used in functions that does too much ! I prefer small functions that do less... Best, Chris -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with unsubscribe in the subject, without the quotes.

I'm still finding my way with REBOL, from a design and style perspective, so my view is hardly something to be taken as gospel. I find myself in the same situation as you (my view is not to be taken as gospel), however I do find myself in a position where my project would benefit from a better implementation of OOP for Rebol...

Caveat emptor, I haven't built any large systems with REBOL, where OOP might really shine. I know about Carl's recovering, we have yet to know if he has fully recovered ;) I can understand his point of view and respect his decision for Rebol. However, I'm a bit of a doubting Thomas, and since I daily work in OOP and I daily see it's results and qualities for a delivered product, I'm a believer. Furthermore, I'm quite happy he has offer us basic OOP functionality in Rebol, if it wasn't for these, I would have probably liked Rebol for small projects/scripts, but not for big ones/applications and I have a big one in mind ;) Why Rebol and not another pure OOP languages ? Because I like Rebol, I'm a believer ! I look forward to seeing your results if you pursue them. Thanks, I hope I can achieve an infrastructure which will interest others !
