推荐答案

尝试将此代码( Open.cpp )编译为 Open.exe 然后，您可以使用(例如)以下参数执行它:

Try to compile this code (Open.cpp) to Open.exe Then, you can execute it with (for example) these parameters :

打开"C:\ your file.doc"

打开"C:\ your file.exe"

打开记事本

#include "windows.h"

int main(int argc, char *argv[])
{
    ShellExecute(GetDesktopWindow(), "open", argv[1], NULL, NULL, SW_SHOWNORMAL);
}

程序说明:

1. 您应该首先包含Windows库( windows.h )来获取 ShellExecute 和 GetDesktopWindow 函数.
2. ShellExecute 是使用参数执行文件的功能 argv [1] 是要打开的文件的路径
3. lpOperation 的另一个选项参数而不是"open" 是空值."explore" 和"find" 还有选择，但它们不是用于打开文件.
4. SW_SHOWNORMAL 是以正常模式显示程序(不显示最小化或最大化)

1. You should first include windows library (windows.h) to get ShellExecute and GetDesktopWindow function.
2. ShellExecute is the function to execute the file with parameter argv[1] that is path to the file to be opened
3. Another option for lpOperation arguments instead of "open" is NULL. "explore" and "find" are also the options but they are not for opening a file.
4. SW_SHOWNORMAL is the constant to show the program in normal mode (not minimize or maximize)
