使用ShellExecute和CreateProcess执行外部操作-优快云博客

本文介绍了如何使用ShellExecute和ShellExecuteEx API在Windows中执行各种外部操作，如打开应用程序、文档、网页、发送邮件以及打印文档。同时，展示了如何启动一个程序并等待其运行结束，以及如何显示文件或文件夹的属性。另外，还提到了WinExec和CreateProcess函数作为执行外部程序的替代选项。

1.HINSTANCE ShellExecute(
    HWND hwnd,             // 父窗口句柄 NULL
    LPCTSTR lpOperation,   // 动作 "Open" "edit" "explore"..
    LPCTSTR lpFile,        // 要通过动作来操纵的文件对象 "notepad"
    LPCTSTR lpParameters, // 若lpFile为可执行文件,lpParameters就是该可执行文件的命令行参数 "test.txt"
    LPCTSTR lpDirectory,   // 默认目录 NULL
    INT nShowCmd           // SW_HIDE ,SW_MAXIMIZE ,SW_MINIMIZE SW_SHOW SW_SHOWDEFAULT....
);

BOOL ShellExecuteEx(
LPSHELLEXECUTEINFO lpExecInfo
);

应用:
打开一个应用程序:
         ShellExecute(this->m_hWnd,"Open","calc.exe","","",SW_SHOW);
打开一个同系统程序相关连的文档:
         ShellExecute(this->m_hWnd,"open","c://abc.txt","","",SW_SHOW);
打开一个网页:
         ShellExecute(this->m_hWnd,"open","http://www.google.com","","",SW_SHOW);
激活相关程序，发送EMAIL:
         ShellExecute(this->m_hWnd,"open","maito:future_fighter123@yahoo.com.cn","","",SW_SHOW);
用系统打印机打印文档:
         ShellExecute(this->m_hWnd,"print","c://abc.txt","","",SW_HIDE);
用系统查找功能来查找指定文件:
         ShellExecute(this->m_hWnd,"find","c:/windows",NULL,NULL,SW_SHOW);
启动一个程序，直到它运行结束:
SHELLEXECUTEINFO ShExecInfo = {0};
ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
ShExecInfo.hwnd = NULL;
ShExecInfo.lpVerb = NULL;
ShExecInfo.lpFile = "c://MyProgram.exe";
ShExecInfo.lpParameters = "";
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_SHOW;
ShExecInfo.hInstApp = NULL;
ShellExecuteEx(&ShExecInfo);
WaitForSingleObject(ShExecInfo.hProcess,INFINITE);
     或者:
PROCESS_INFORMATION ProcessInfo;
STARTUPINFO StartupInfo; //This is an [in] parameter
ZeroMemory(&StartupInfo, sizeof(StartupInfo));
StartupInfo.cb = sizeof StartupInfo ; //Only compulsory field
if(CreateProcess("c://winnt//notepad.exe", NULL,
     NULL,NULL,FALSE,0,NULL,
   NULL,&StartupInfo,&ProcessInfo))
{
     WaitForSingleObject(ProcessInfo.hProcess,INFINITE);
     CloseHandle(ProcessInfo.hThread);
     CloseHandle(ProcessInfo.hProcess);
}
else
{
     MessageBox("The process could not be started...");
}
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://"; //can be a file as well
ShExecInfo.lpParameters = "";
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_SHOW;
ShExecInfo.hInstApp = NULL;
ShellExecuteEx(&ShExecInfo);

2.UINT WinExec(
LPCSTR lpCmdLine, // 命令行参数
UINT uCmdShow // 显示方式,和ShowWindow的一样
);

3.BOOL CreateProcess(
LPCTSTR lpApplicationName,
LPTSTR lpCommandLine,
LPSECURITY_ATTRIBUTES lpProcessAttributes,
LPSECURITY_ATTRIBUTES lpThreadAttributes,
BOOL bInheritHandles,
DWORD dwCreationFlags,
LPVOID lpEnvironment,
LPCTSTR lpCurrentDirectory,
LPSTARTUPINFO lpStartupInfo,
LPPROCESS_INFORMATION lpProcessInformation
);
