ShellExecuteEx Performs an action on a file. BOOL ShellExecuteEx( LPSHELLEXECUTEINFO lpExecInfo );If the function succeeds, it sets the hInstApp member of the SHELLEXECUTEINFO structure to a value greater than 32. If the function fails, hInstApp is set to the SE_ERR_XXX error value that best indicates the cause of the failure. Although hInstApp is declared as an HINSTANCE for compatibility with 16-bit Microsoft Windows applications, it is not a true HINSTANCE. It can only be cast to an integer and compared to either 32 or the SE_ERR_XXX error codes.
shellexecute 不能得到真正的句柄，你要用 createprocess, 然后waitforsingleobject: STARTUPINFO si; PROCESS_INFORMATION pi; ZeroMemory(&si,sizeof(si)); si.cb=sizeof(si); ZeroMemory(&pi,sizeof(pi)); // Start the child process. CreateProcess(NULL, // No module name (use command line). "notepad", // Command line. NULL, // Process handle not inheritable. NULL, // Thread handle not inheritable. FALSE, // Set handle inheritance to FALSE. 0, // No creation flags. NULL, // Use parent's environment block. NULL, // Use parent's starting directory. &si, // Pointer to STARTUPINFO structure. &pi) // Pointer to PROCESS_INFORMATION structure. WaitForSingleObject(pi.hProcess, INFINITE); // Close process and thread handles. CloseHandle( pi.hProcess ); CloseHandle( pi.hThread );记得多给分：））
ZouMorn(默文) 的代码比较管用哦
SHELLEXECUTEINFO ShExecInfo = {0}; ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO); ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS; ShExecInfo.hwnd = NULL; ShExecInfo.lpVerb = NULL; ShExecInfo.lpFile = "c:\\winnt\\notepad.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..."); }
HWND hwnd,
LPCTSTR lpVerb,
LPCTSTR lpFile,
LPCTSTR lpParameters,
LPCTSTR lpDirectory,

函数的返回值不是真正的HINSTANCE,从而不能再程序中使用它进行窗口的关联！
你最好再打开了notepad后，
用函数CWnd::FindWindow(....)去捕捉你打开的窗口，利用该函数返回的CWnd*
然后::IsWindow(pWnd->m_hWnd);判断窗口是否还存在
LPSHELLEXECUTEINFO lpExecInfo
);
看看这样行不行.
得先得到关联到某种文件的程序的位置,然后列举当前所有进程,检查该进程的路径和可执行文件名是否和先前得到的一致,如果是就证明该程序没有关闭,不然就是关闭了.
例如已经打开多个word文档
