在程序中我用 WinExec 启动了另一个程序，怎样判断该程序什么时候结束！

[ra3]

多谢了！

用ShellExcute 执行
用WaitForSingleObject等待其结束

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...");
}

WaitForSingleObject

用FindWidow
假设该程序的标题是"Title"

WinExec("mytest.exe", SW_SHOW);
CWnd *pWnd;
while(TRUE)
{
pWnd = FindWindow(NULL, "Title");
if(pWnd == NULL)
{
//程序已经结束
break;
}
}

1.得到该进程的进程句柄HANDLE hProcess;再WaitForSingleObject(hProcess,INFINITE),如用CreateProcess启动,则返回值中有hProcess,不必另外查找.
2.定时查找进程的主窗口FindWindow(),如存在表明没有退出.
3.Toolhelp函数,不过太难用.

启动程序的函数会返回一个句柄。
你调用WaitForSingleObject()函数就可以了，该函数可以实现在程序退出的时候会返回。

通过信号量

SHELLEXECUTEINFO
在哪个头文件里面定义的啊？
windows.h 头文件里没有这个
