Windows-CreateProcess函数使用

原創 小撇儿1992 2020-05-30 15:44

工作的时候遇到一个bug，由一个程序通过CreateProcess函数唤起另外一个程序，由于第一个参数ApplicationName没有写绝对路径，导致程序唤起失败。

1.主调进程.EXE文件所在的目录

2.主调进程的当前目录

3.Windows系统目录，即GetSystemDirectory返回的System32子文件夹

4.Windows目录

5.PATH环境变量中列出的目录

CreateProcess函数的LPCTSTR lpCurrentDirectory(子进程的工作目录)参数最好指定一下，如果不指定的话，有些依赖子进程的窗口会有问题
