Yes, that bother all wsh scripters. No way to hide wshExecobject, only .Runallow this option, but no StdOutin this case. Shortly, the only way is to redirect your output to file.
是的，这困扰着所有 wsh 脚本编写者。无法隐藏wshExec对象，只.Run允许此选项，但StdOut在这种情况下不允许。很快，唯一的方法就是将您的输出重定向到文件。
WshShell = new ActiveXObject("WScript.Shell");
var launch ="cmd.exe /c java -classpath . HelloWorld > output.txt";
var cmdRun = WshShell.Run(launch,0,true);
