Forum: Ruby "Open" dialog of Windows

Hi guys, been researching about pop up the "open" file dialog of
Windows. I didn't find nothing, just a snippet of code that doesn't
work:


require "win32ole"

cd = WIN32OLE.new("MSComDlg.CommonDialog")

cd.filter = "All Files(*.*)|*.*" +"|Ruby Files(*.rb)|*.rb"
cd.filterIndex = 2

cd.maxFileSize = 128    # Set MaxFileSize

cd.showOpen()

file = cd.fileName      # Retrieve file, path

if not file or file==""
   puts "No filename entered."
else
   puts "The user selected: #{file}\n"
end


 Do you have the way to do that? Thank you.

i cannot answer the win32ole part, but, ..  regarding gui dialogs, you 
may
want to try tk. simpler and works on almost all platform..

eg to select a .rb file, and then print its content,

>require 'tk'
>puts File.read Tk::getOpenFile( 'filetypes'=>[['Currently', '*.rb']] )

tested to run in windows/linux/aix unix

kind regards -botp

That's cool botp but I'm trying to not use any external gem rather than 
FXRuby gem, if I include Tk plus all the gems that I'm using for my 
project(roo, win32ole, etc..) the final pack will be big and I don't 
think that the fusion between both frameworks will be nice for the user, 
I mean FXRuby widgets are pretty differents that the Tk ones. The 
problem with the dialog in FXRuby is that its in English, I'm developing 
an Spanish language app, so I can not pop up a dialog in English 
expecting that the user will understand what said there. The solution 
for me will be if I can pop up the "open" file dialog of Windows(I'm 
developing just for windows). Of course I can create my own widget for 
file opening but you know, everything takes time, and now I'm running 
low, need the help you all can give me, thanks.

Is this what you're looking for?

http://www.fxruby.org/doc/api/classes/Fox/FXFileDialog.html

It is completely in english, as I said, the app is in spanish language. 
Was wondering if I can save time using the windows open file dialog 
instead of develop a new widget like the one you showed, I'm trying to 
make a professional app so I don't want for example that the button 
'cancel' say  'cancel' in it, it must be 'cancelar', spanish...

Doesn't the windows dialog correspond to the language currently in use 
in the operating system?

 If you mean the #FXFileDialog from FXRuby then NO. I've tested it. It's 
always in English. If you mean the "Windows OS open dialog"(I mean the 
one which say "Open" as caption in English version and "Abrir" in 
Spanish version) then it depends of the language currently in use in the 
operating system, and that's what I want... because in this case the app 
is explicit for a user which is working in a PC with spanish language.

I'd suggest looking into how that dialog is created and whether it's 
possible to change the source to something more suitable for your 
project.

Have you tried asking the "Spanish Rails Group" on here? Someone there 
might have already solved this problem.

 Well, FXRuby is basically a wraper to the C++ Fox framework, so the
pre-mades widgets are in some way hidden in C++ code, as I can't 
interpret C++ code I can't do nothing. What I can do is combine a group 
of widgets until that groups becomes a sort of "file open dialog", but 
I'm trynig to avoid that because it takes time, and am low of it.

 That's a good recomendation! I think is even better ask in the Ruby on 
Rails group since this is a global question, not explicit to some 
language. Thank you Joel.

 So if still anyone can help. I'll be thankfull. :)

Short answer: see http://www.ruby-forum.com/topic/168114

Long answer:
It would have been helpful to include the error message and the Windows 
and
Ruby software versions you are using. See
http://www.catb.org/esr/faqs/smart-questions.html#beprecise

Trying your example on Windows 7 Ruby 1.9.3 I get
Win32_Test.rb:3:in `initialize': unknown OLE server:
`MSComDlg.CommonDialog' (WIN32OLERuntimeError)

This suggests that component is not installed on my machine. Even if it 
was
installed, Google suggests there would be a Microsoft component 
licensing
issue:
http://dutchgemini.wordpress.com/2010/12/23/vba-ca...


If you insist on solving your problem by using native Windows dialogs, 
an
alternative to an OLE component would be to access the Win32 API 
directly:
http://www.ruby-doc.org/docs/ProgrammingRuby/html/...

See Win32 GetOpenFileName():
http://msdn.microsoft.com/en-us/library/ms646927%2...
http://msdn.microsoft.com/en-us/library/ms646829(v...

GetOpenFileName() is deprecated but is probably easier to use than the
alternative. However, it will involve packing the OPENFILENAME members, 
as
in the example I linked to at the start of my email.

Feliz Navidad,
Kieran

 Same OS and Ruby version.

 Same thing happen to me, I've been in that page. I've tried the
solution but doesn't work for me, seems that the component is not
installed on my machine.

 Well, this solution can be a mess, since I've scaped every time that I
looked to the Win32API, it hurst me. Seems that finally I have to appeal
to construct the entire widget with FXRuby.
