VC调用其他程序以及用其他程序打开相应文件

深入浅出ShellExecute
译者：徐景周(原作:Nishant S)

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:[email protected]","","", SW_SHOW );

Q: 如何用系统打印机打印文档？

ShellExecute(this->m_hWnd,"print",
    "c://abc.txt","","", SW_HIDE);

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);

下面是我自己的代码,调用word打开doc或docx文件

void COPenFileDlgDlg::OnBnClickedButton1()
{
	// TODO: 在此添加控件通知处理程序代码
	
	//CFileDialog dlg(TRUE); //TRUE是显示为打开对话框,FALSE为另存为对话框 
	CString  strPathName;
	CString  strFileName;
	CString  strFlieTitle;
	CFileDialog dlg(TRUE,NULL,NULL,OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,_T("WORD文件(*.doc)|*.doc;*.docx|所有文件(*.*)|*.*||"));
         //||是指定分开,不然后面会有乱码, ";"是用于两种文件格式同时筛选
	if (dlg.DoModal() == IDOK)
	{
		/*
		//方法一
                     strPathName = dlg.GetPathName(); //获取文件路径
		strFileName = dlg.GetFileName(); //获取文件名(包括后缀名)
		strFlieTitle = dlg.GetFileTitle();//获取文件名,没有后缀名
		MessageBox(strPathName + "/n" + strFileName+ "/n" + strFlieTitle);
		*/
		//方法二
		POSITION  pos;
		pos = dlg.GetStartPosition(); //获得最初的变量
		while(pos != NULL)
		{
			strPathName = dlg.GetNextPathName(pos);
			if (!strPathName.IsEmpty())
			{
				//MessageBox(strPathName);
				ShellExecute(this->m_hWnd,_T("open"),_T("WINWORD.EXE"),strPathName,NULL,SW_SHOW);
				//用word程序打开doc文件
			}
		}
		
	}
}
