问题描述

我正在通过 QProcess 使用CMD,但是有问题。

I'm using CMD by QProcess but I have a problem.

我的代码:

QProcess process;
process.start("cmd.exe");
process.write ("del f:\\b.txt\n\r");
process.waitForFinished();
process.close();

当我不传递 waitForFinished()等待30秒。我想在执行CMD命令后终止 QProcess !不多也不少!

When I don't pass an argument for waitForFinished() it waits for 30 secs. I want to terminate QProcess after CMD command is executed! Not much and not less!

推荐答案

您需要通过发送 exit终止cmd.exe 命令,否则将等待命令
这是我的建议:

You need to terminate the cmd.exe by sending exit command, otherwise it will wait for commands Here is my suggestion:

QProcess process;
process.start("cmd.exe");
process.write ("del f:\\b.txt\n\r");
process.write ("exit\n\r");
process.waitForFinished();
process.close();
