ShellExecute详解

ShellExecute()功能: 运行一个外部程序,并对外部程序有一定的控制.

原型:

            HINSTANCE ShellExecute(    HWND hwnd,
                                                            LPCTSTR lpOperation,
                                                            LPCTSTR lpFile,
                                                            LPCTSTR lpParameters,
                                                            LPCTSTR lpDirectory,
                                                            INT nShowCmd
);

hwnd: 父窗口句柄;

lpOperation: 指定进行的操作,默认操作为open;

                   open:执行由lpFile指定的程序,或打开由lpFile指定的文件或文件夹

                   print: 打印由pFile指定的文件

                   explore: 浏览由pFile指定的文件夹

                   find: 从指定的目录开始搜索
lpFile: 指定需要执行指定操作的文件或文件夹

lpParameters: 若lpFile参数是一个可执行程序，则此参数指定命令行参数，否则此参数应为NULL

lpDirectory: 指定默认目录

nShowCmd:若lpFile参数是一个可执行程序，则此参数指定程序窗口的初始显示方式，否则此参数应设置为NULL

返回值: 执行成功则返回大于32的实例句柄,失败则返回小于32的值

实例:

1.打开一个应用程序:

ShellExecute(NULL,"open","D://myprocess.exe","","", SW_SHOW );

2.用系统程序打开一个相关的文档

ShellExecute(NULL,"open","notepad.exe","c://MyLog.log","",SW_SHOW );

3.打开一个网页

ShellExecute(NULL,"open","http://www.google.com","","", SW_SHOW );

4. 发送email

ShellExecute(NULL,"open","[email protected]","","", SW_SHOW );

5.用系统打印机打印文档

ShellExecute(NULL,"print","c://test.txt","","", SW_HIDE);

6.用系统查找功能来查找指定文件

ShellExecute(NULL,"find","d://master",NULL,NULL,SW_SHOW);

7.启动一个程序直到它运行完毕

SHELLEXECUTEINFO ShExecInfo = {0};
ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
ShExecInfo.hwnd = NULL;
ShExecInfo.lpVerb = NULL;
ShExecInfo.lpFile = "c://MyTest.exe";
ShExecInfo.lpParameters = "";
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_SHOW;
ShExecInfo.hInstApp = NULL;
ShellExecuteEx(&ShExecInfo);
WaitForSingleObject(ShExecInfo.hProcess,INFINITE); //等待句柄有信号

8.显示文件或文件夹的属性

SHELLEXECUTEINFO ShExecInfo ={0};
ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfo.fMask = SEE_MASK_INVOKEIDLIST ;
ShExecInfo.hwnd = NULL;
ShExecInfo.lpVerb = "properties";
ShExecInfo.lpFile = "c://Programer Files";

ShExecInfo.lpParameters = "";
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_SHOW;
ShExecInfo.hInstApp = NULL;
ShellExecuteEx(&ShExecInfo);

9.运行一个批处理,把当前运行目录传送进去

ShellExecute(NULL,"open","d://master.cmd",NULL,"D://",SW_SHOW);
