Dos system hide shell

fanticla has asked for the wisdom of the Perl Monks concerning the following question:

Dear monks,

I compiled a TK application for Windows. From this application I start an external exe file using "system", namely to convert a pdf file into text. It works perfectly, but every time the dos shell is prompted (for the time the pdt2text converter works), and as this is a batch operation, the thing is very annoying. There is a way to hide the dos shell?

while ($pdf) {
system ("pdftotext.exe  my_pdf.pdf");
}
[download]

Thanks, cla

See How to hide the command prompt open duing the execution of system command?, note it isn't a DOS window, it's a Command_Prompt, while similar in some ways they are different things.	[reply]

FWIW a google advanced search is often the way to go. Cheers	[reply]

Invoke your program through the wperl.exe rather than the perl.exe. Saving your code as .wpl file instead of .pl file can be the most direct forward thing to do to solve this. In case the extension association is not set then you may need to define a new file type for .wpl as wperl scripts for you to be able to use your program without a console..but first of all try this at the top of your code `#!/usr/local/bin/wperl` to point to the wperl executable and see what happens otherwise there are many ways to do this, consider: Tk and the command line window. perl in the background under windows?. http://community.activestate.com/forum-topic/wperl-via-perl-detatching. other discussions.
