博客给出了C语言执行外部程序的代码示例。一是使用SHELLEXECUTEINFO结构体和ShellExecuteEx函数，二是使用PROCESS_INFORMATION和STARTUPINFO结构体及CreateProcess函数，还包含等待进程结束和关闭句柄等操作。

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： 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...");
}
