ShellExecute与ShellExecuteEx的用法

ShellExecute函数原型及参数含义如下： 

ShellExecute( 

HWND hwnd, //父窗口句柄 

LPCSTR lpOperation, //操作类型 

LPCSTR lpFile, //要进行操作的文件或路径 

LPCSTR lpParameters, //当lpOperation为 "explore" 时指定要传递的参数，通常设为NULL 

LPCSTR lpDirectory, //指定默认目录，通常设为NULL 

INT nShowCmd //文件打开的方式，以通常方式还是最大化或最小化显示 

) 

BOOL ShellExecuteEx(
  __inout  LPSHELLEXECUTEINFO lpExecInfo
);

Q: 如何启动一个程序，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：
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...");
}

ShExecInfo.lpFile = "c:\\"; //can be a file as well
ShExecInfo.lpParameters = "";
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_SHOW;
ShExecInfo.hInstApp = NULL;
