Hi,
I’ve got a problem. I want to close any Internet Explorer Window, even those
ruby didn’t open with WIN32OLE.
Does anyone know how to do this?

thanks

I’m guessing your best bet will be to dive into API calls (see Win32API).
There are routines to enumerate existing windows and get handles to them,
you should be able to shut them down that way.

Sorry I don’t have more specifics, it would take some digging. But hit up
groups.google.com and I’m sure you can find some non-Ruby code to do this.

here is the code I am using (to only close IE windows that I have opened)

require ‘win32ole’

iefrom = WIN32OLE.new(‘InternetExplorer.Application’)
iefrom.visible = true

iefrom.navigate “http://www.yahoo.com”
#sleep 2 while @iefrom.Busy == true

iefrom.quit #this is actually what closes the window.

As far as I know, Win32API.so can not support API that uses a
callback procedure such as EnumWindows(). Ruby/DL will be the
better one for his problem.

Ruby/DL – http://www.ruby-lang.org/en/raa-list.rhtml?id=629

require ‘dl’

User32 = DL.dlopen(“user32”)
enum_windows = User32[‘EnumWindows’, ‘IPL’]
post_message = User32[‘PostMessage’, ‘ILILL’]
get_class_name = User32[‘GetClassName’, ‘ILpI’]

name = “IEFrame”
buff = " " * 16
WM_CLOSE = 0x0010
TRUE = 1

enum_windows_proc = DL.callback(‘ILL’) {|hwnd,lparam|
r,rs = get_class_name.call(hwnd, buff, buff.size)
if /^#{name}$/ =~ rs[1].to_s
r,rs = post_message.call(hwnd, WM_CLOSE, 0, 0)
end
TRUE
}

r,rs = enum_windows.call(enum_windows_proc, 0)

Ruby/DL – http://www.ruby-lang.org/en/raa-list.rhtml?id=629
…
require ‘dl’

In the alternative, we rewrite your code with `dl/import.rb’ as follows.

require ‘dl/import’

module Foo
extend DL::Importable

dlload “user32”

extern “BOOL EnumWindows(void *, long)”
extern “BOOL PostMessage(long, int, long, long)”
extern “BOOL GetClassName(long, void *, int)”

WM_CLOSE = 0x0010

def enum_windows_proc(hwnd, lparam)
buff = DL.malloc(16)
name = “IEFrame”
r = getClassName(hwnd, buff, buff.size)
if /^#{name}$/ =~ buff.to_s
r = postMessage(hwnd, WM_CLOSE, 0, 0)
end
1
end

EnumWindowsProc = callback “int enum_windows_proc(long, long)”
end

Foo.enumWindows(Foo::EnumWindowsProc, 0)

Cool stuff - I didn’t even know about Ruby/DL - thanks for the posts.

I only have a windows environment. Does anybody know how to install the
Ruby/DL library in Ruby under Windows???

Thanks

You can use Ruby 1.7.2 or compile dl/import according to the install
instructions using Visual C++.

Even if you think i’m dumb, but he asks me for a file named dlfcn.h and
windows.h if i want to create the makefile.
I don’t have much experience in c++.
And i can’t use 1.7.2 because, it’s missing some functions i need.
Do you have suggestions to solve this problem?

I don’t have any suggestions about compiling problem, but
here is a binary package.

http://www.dm4lab.to/~usa/ruby/index_en.html

At the “Extention libraries” section in the above page, you
can find the “Ruby Shim” which include dl.so for ruby 1.6.
