推荐答案

CreateProcess 和 ShellExecute 的主要区别如下: CreateProcess更面向低级别，ShellExec 位于高用户级别，可以在资源管理器中看到用户.

The main difference between CreateProcess and ShellExecute is the following: CreateProcess is more oriented on low level and ShellExec on the high user lever which see the user in explorer.

例如使用CreateProcess 可以使用长度大于MAX_PATH 的命令行.它有 32,768 个字符的限制.您还可以使用 CreateProcess 在另一个 Windows 桌面(如登录屏幕)上启动程序(如果您有足够的权限).

For example using of CreateProcess one can use command line which length is more as MAX_PATH. It has 32,768 characters restriction. You can also use CreateProcess to start program (if you have enough permissions) on another windows desktop like on the Logon Screen.

另一个例子.您可以使用 ShellExecute 来启动控制面板或打开计算机上存在的任何程序来编辑 JPG 文件.因此，您可以使用 ShellExecute 接近 Windows 资源管理器中的相应操作.

Another example. You can use ShellExecute to start Control Panel or open any program which existed on the computer for editing of JPG filed for example. So you works with ShellExecute close to the corresponding actions in the Windows Explorer.
