Q: 如何打开一个应用程序？

ShellExecute(this->m_hWnd,"open","calc.exe","","", SW_SHOW );

或

ShellExecute(this->m_hWnd,"open","notepad.exe","c:\\MyLog.log","",SW_SHOW );

正如您所看到的，我并没有传递程序的完整路径。
Q: 如何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 );

Q: 如何打开一个网页？

ShellExecute(this->m_hWnd,"open","http://www.google.com","","", SW_SHOW );

Q: 如何激活相关程序，发送EMAIL？

ShellExecute(this->m_hWnd,"open","mailto:nishinapp@yahoo.com","","", SW_SHOW );

Q: 如何用系统打印机打印文档？

Q: 如何用系统查找功能来查找指定文件？

ShellExecute(m_hWnd,"find","d:\\nish",NULL,NULL,SW_SHOW);

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...");
}

Q: 如何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);
