REBOL & OLE Automation

[Thør]

Hi!

I'd like to know if REBOL is capable of using OLE automation. A link or tutorial/sample script on how to do it is highly appreciated.

Thanks.

Not directly according to the only thread on the Rebol ML that mentions OLE - http://www.rebol.org/cgi-bin/cgiwrap/rebol/ml-display-thread.r?m=rmlSHDC

Thanks. You have just also reminded me that the first thing to do immediately before or after posting a question here is to check the ML.  ^_^

You could also see the great work supplied by Benjamin Maggi.

COMLib.zip and others archives with docs

Works fine. Need SDK or Pro.

Thanks for the information. Will study it a bit later. 

Cheers!! :mellow:

I've extensively reworked Benjamin's COMLib, cleaning and enhancing it. Here's the website:

Hi Anton.

My interest in REBOL and COM have been revived recently, and I tried running the test-COMlib.r script included web page in the link you provided. Unfortunately, I received this error:

Code:

** Script Error: foreach expected data argument of type: series
** Where: cleanup
** Near: foreach obj objects [routines/releaseObject obj]

I'm currently running:

version        1.3.2.3.1
build           5-Dec-2005/18:22:54-8:00
product       View
core            2.6.3

Thanks.

Hi Thør,

I think you get this error because you don't have the Rebol SDK or View/Pro license ?
COMLib uses Rebol's External Library Interface and as such needs a license.
If so, you are not the first to be confused. I'll try to make the website clearer to
avoid future disappointments.

Before your script error, did it print out a large error object beginning with this?:

make object! [
    code: 328
    type: 'script
    id: 'feature-na        ; <--- that's a "feature not available" error.
   .... etc

Sorry for any disappointment.
Regards,

Anton.

Anton,

Thanks for the tip. I have a license for Command, and after a little investigation,  I found out that the error is caused by a missing com2rebol.dll file. Looks like I forgot to extract it from the zip file to the folder that test-COMLib.r is in.

I'm going to play around with it this weekend.

Cheers!

Thør, thanks for your error reports. I've added the need for better error messages for these cases to the to-do list. Glad it was something relatively simple.

(for Anton)

Hello Anton,

When I use the COMLib library, REBOL returns the message :

make object! [
    code: 300
    type: 'script
    id: 'no-value
    arg1: 'case
    arg2: none
    arg3: none
    near: [case [
            find all-routine-names dependency [if not find my-routines dependency [append my-routines dependenc
y]]
            find all-function-names dependency [if not find my-functions dependency [append my-functions depend
ency]]
            "default" [
                throw make error! reform ["COMLib: The function" name "depends on" dependency "but" dependency
"is not available."]
            ]
        ]]
    where: 'initialize
]

I use REBOL/Command View 1.2.48.3.1 on XP or (same error) REBOL/Command View 1.2.10.3.1, with simple-start-comlib.r script.

Could you help me  ?
Thx,
===Philippe

Ah.. it looks like those older rebol versions don't have the CASE function yet. Forgive me for assuming new rebol versions.
It appears that View 1.2.54.3.1 was the first version with CASE.
Options:
- require a newer rebol version (pop an alert when too old versions are used)
- implement CASE as a mezzanine (it might work, but there might be other backwards compatibility issues, some other functions might be missing)
- rewrite the code not using CASE

[Anton]

Philippe,

Ok, I have made some backwards compatibility fixes.
Now it should work back to View >= 1.2.30
(if all is well - only lightly tested with %test-comlib.r.)

Get %COMLib.r

http://anton.wildit.net.au/rebol/os/windows/COMLib/files.html

and replace your old one in your COMLib folder.

Let me know how it goes, and sorry, I didn't see your report until today.

[Philippe]

Anton,

OK, thanks.
I will test the release and keep you informed.

rgds,
Philippe
