PPM 4 can't find package widget::statusbar

OS: All / Any | Product: ActivePerl | tags: activeperl environment gui PPM ppm4 vpm
Question:

When I try to run PPM 4 in graphical mode it complains that it can't find the widget::statusbar package and exits. How do I make this work?

Answer:

The problem is likely that you have the PERL_TCL_DLL environment variable set. This variable is set when you are using the Tkx GUI toolkit. PPM 4 also uses Tkx, but has its own version of Tkx bundled; hence, the environment variable points PPM 4 away from its version and to your ActiveTcl installation, which doesn't have all of the files necessary to run PPM 4.

The solution is to unset that environment variable before running PPM 4.

Suppress console windows when using backticks

OS: Windows | Product: Perl Dev Kit | tags: gui perlapp
Question:

How do I stop console windows from popping up when i call commands in backticks?

Answer:

Using perlapp's --gui option should hide normal perl command line output, but system commands called within backticks may still open command line windows. To suppress this, try adding the following block to your script:

BEGIN {
    Win32::SetChildShowWindow(0) if defined &Win32::SetChildShowWindow;
}

This should work using ActivePerl version 632 or later.
