Windows command line appears when using 'system()'

[crazynoob04]

I have this script:

require 'tk' require 'tkextlib/tile'

root = TkRoot.new()

button = Tk::Tile::TButton.new(root) {text "Hello World"}.grid button.command {system("ipconfig > info.txt")}

Tk.mainloop()

The script runs fine and there are no errors, but when i build it with ocra, and i click the 'Hello World' button from the exe file, the cmd will appear for less then a second, and this, everytime i press the button.

I also tried Open3.popen3(cmd), but still the same issue as with system().

If i remove or comment this line:

button.command {system("ipconfig > info.txt")}

Then the issue will disappear, so i think the problem is related to system().

I tried to rename my ruby file from .rb to .rbw too, and also to add --windows [path\to\tk] --add-all-core, still nothing.

This is my ruby version: ruby 2.3.0p0 (2015-12-25 revision 53290) [x64-mingw32]

This issue will appear on the following ruby versions too: ruby 2.1.5p273 (2014-11-13 revision 48405) [x64-mingw32] ruby 2.0.0p648 (2015-12-16) [x64-mingw32] ruby 1.9.3p551 (2014-11-13) [i386-mingw32]

I solved this by myself.

First thing i required this in my script:

require 'win32ole'

Then i made a batch file, containing the command i need to be printed on a file, in this case ip config > info.txt, and i named it run.bat.

After this, I replaced system() with the following:

WIN32OLE.new('Shell.Application').ShellExecute('run.bat','','','open',0)

As first parameter i used the batch file i just created, and the last parameter, the 0, made the trick. It sets the new cmd windows to be hided and so it wont ever pop up again.

I tried with rubyw efdsk.rb and also to build an exe with ocra. No annoying windows popping up. This wans't an ocra issue. Sorry for posting here.
