Hello everyone, I have this simplest perl code: ..... my $dev_com = 'devenv.exe '; my $dev_com_opt = '/Build Release'; my $full_proj = 'FullBuild.sln'; RunCmd("$dev_com $full_proj $dev_com_opt"); ..... It seems that the CMD executes with no warnings but when you see on windows Task Manager, the process has already started.... What can I do to capture build solution and have this command execution finish when the solution is finished? Cheers,
