请教个问题：我用VC写了个单文档的程序A，然后要在另外一个VC写的程序的菜单项中 点下菜单项就打开程序A，有这种的函数吗？或者解决方法吗？

先谢谢了

Answer 1

使用ShellExecute（）或ShellExecuteEx（）

ShellExecute与ShellExecuteEx的用法
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？
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);

调用一个exe程序的方法可以参考下下面这个函数：

//
// 函数: void ExecFile( TCHAR* szFile, BOOL bWait = FALSE )
//
// 目的： 运行一个程序
//
// 参数:
// szFile
// [in]: 要执行的文件的路径
// bWait:
// [in]: 是否要等待该程序运行结束
//
void ExecFile( TCHAR* szFile, BOOL bWait )
{
SHELLEXECUTEINFO ExecInfo;
::ZeroMemory( &ExecInfo, sizeof( SHELLEXECUTEINFO ) );
ExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
ExecInfo.cbSize = sizeof( SHELLEXECUTEINFO );
ExecInfo.hwnd = NULL;
ExecInfo.lpVerb = _T("open");
ExecInfo.lpFile = szFile;
ExecInfo.nShow = SW_SHOW;
::ShellExecuteEx( &ExecInfo );

if(bWait)
::WaitForSingleObject( ExecInfo.hProcess, INFINITE );

::CloseHandle( ExecInfo.hProcess );
}

在菜单消息响应函数里调用这个函数
