Qt6 程序开机自启找不到配置文件及外部程序

网友投稿 617 2022-05-29

欢迎来到我的博客,希望这篇文章对你有所帮助,如果觉得不错,请搜藏哈。

1. 场景描述

还是用开机助手这个软件来举例,软件在编译打包完成后,正常启动后,可以正常读取到与其同级目录下BAT文件中的关机脚本的,如下图

经过测试,是没有问题,但是呢,当我们把程序设置为开机启动,在程序开机自启动后,无法读取程序的关机脚本。

2. 查找原因

2.1 权限原因

在开始部署的时候,把程序安装到了C盘,开始怀疑是不是因为给的权利不够,在给了全部权限后,还是不可以。排除权限问题。

2.2 在部署目录运行

在部署目录手动启动,程序可以正常执行,可以读取到关机脚本。

2.3 文件路径问题

经过百度后,才明白,如果我们把程序设置为开机启动后,因为开机启动的指令其实也是CMD的指令,所以,如果我们在代码中使用以下代码获取程序路径,其实获取到的是CMD程序的运行路径,也就是“C:\Windows\System32”,所以会发现找不到文件

QString appPath = QApplication::applicationFilePath();

3. 解决方法

解决方案也很简单,就是把获取程序路径的代码修改一下,如下:

QString curPath = QCoreApplication::applicationDirPath();

问题解决

附上源码
