Re: AW: Launch an external application from visual works

In addition you can start an application via opening well know file types.

Load parcel "Windows Godies" and do the following:

MinimalShellInterface openFile: 'xyz.pdf' from:Dialog defaultParentWindow.

it will open Adobe reader in this example.

If you use file as: 'http://yahoo.com' it will open default browser.

Re: AW: Launch an external application from visual works -->>>So what about file Icons

Hi,

The windows goodies seem to be able to do quite a number of things. Now
what about obtaining the platform file icons in readable graphics format
to show these in a list ?

Do you know about away to obtain these ?

Thanks,

@+Maarten,

Using ExternalProcess?

ExternalProcess defaultClass cshOne: 'some command'

The cshOne: method is very cool for single shot commands, but how would I
use ExternalProcess with an interactive program like mail or ftp?

Also, is this functionality effectively the same for Windows and Unix? My
guess is that Windows doesn't support piping in the same way as Unix.

Carl,

WinProcess supports piping. Technically opens a cmd.com and talks to
programs like ftp and whatever you have.

Carl,

What do you mean with "interactive program"? Do you want start an
external programm and keep getting data to/from it?

Try External-Process-Streams - this strips away the need to use the
command shell to do piping in/out of applications. So it works on
Windows like it does on Unix - it has a common API across all platforms.

Re: Using ExternalProcess?

In reply to this post by Carl Gundel

Hey Cesar,

I am trying to create a generic mechanism for my web programming platform
Run BASIC so that the programmer can interact with external programs. These
could be FTP, MAIL, or some custom scripts written in Perl, etc. I would
like to use ExternalProcess for this. So far I have not managed to make it
work.

So far I've been experimenting in a workspace trying to interact with FTP
from the command line. I've tried various combinations of executeCommand:,
executeSingleCommand:, readPipe, readFromPipe, and writePipe:. So far all
I've managed to do is hang. Ctrl+Y sometimes recovers. When it does, that
instance of WinProcess is now useless.

Also, it seems strange that UnixProcess and WinProcess both inherit from
ExternalProcess but there is no shared protocol between the two. :-/

Thanks Michael. I loaded the latest version of this from the public Store
and there are only a few instance methods in the new WindowsProcess class:

bufferSize
getStatusCode
initialize
kill
kill:

I'm not sure how I would use this new class to do what I need. Any ideas?

Heh - as the package comment says:

ExternalProcess execute: command arguments: arguments do: [:readStream
:writeStream | ] errorStreamDo: [:errorStream | ].

eg:

ExternalProcess execute: 'irb' arguments: '-i' do:
[:readStream :writeStream |
writeStream nextPutAll: '1 + 2'; cr.
readStream upToEnd inspect]
errorStream: [:errorStream | self error: errorStream upToEnd].

I went looking for this cos I have a need for it too. Are 'External',
'Process', 'Streams' packages, bundles, classes, ???.

Where is it?

Re: Using ExternalProcess?

ExternalProcessStreams is a package in public store.

I've had previous reports of situations where using the API in this
package fails. If you try it and you do have a failure - please post it
back to this thread.

FixedPoint comment -- "Object Reference" info

In reply to this post by Daniel Klein-4

After reading a recent thread in c.l.smalltalk, I got curious about this
class.

I think we have some leftover from earlier versions:

<quote>
Object Reference:
FixedPoint numbers are typically used in business applications, for
monetary amounts and similar quantities that require a fixed number of
digits after the decimal point, as well as an unlimited number of digits
before the decimal point. In contrast, a floating point number (Float or
Double) is awkward for business usage because its precision is limited
and the number of post-decimal digits varies.
A FixedPoint number is typically created by sending an #asFixedPoint:
message to a different kind of number, such as a Float, with the number
of post-decimal digits as the argument. For example:
(200 / 3) asFixedPoint: 2 = 66.67f
A FixedPoint can also be written literally, by placing the letter 'f'
after an integer or floating point number.
</quote>

Now in the workspace:

66.67s class returns "FixedPoint"

However:

66.67f class raises the exception MNU: #f

Re: FixedPoint comment -- "Object Reference" info

Looks like just a typo to me -- I don't ever remember 'f' being used to
create fixedPoint. If anything,
I would expect it to create float, as '66.67d' would create double, but
I think it just needs to be chagned to 's'.

Yes. My impression as well. Albeit 'f' does not mean float either.

Is a minor typo which in due time (release) could be taken care of.
