【急】怎样判断ShellExecute是否执行完毕？

改用CreateProcess吧
void main( VOID )
{
    STARTUPINFO si;
    PROCESS_INFORMATION pi;    ZeroMemory( &si, sizeof(si) );
    si.cb = sizeof(si);
    ZeroMemory( &pi, sizeof(pi) );    // Start the child process.
    if( !CreateProcess( NULL, // No module name (use command line).
        "MyChildProcess", // 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.
    )
    {
        ErrorExit( "CreateProcess failed." );
    }    // Wait until child process exits.
    WaitForSingleObject( pi.hProcess, INFINITE );    // Close process and thread handles.
    CloseHandle( pi.hProcess );
    CloseHandle( pi.hThread );
}

楼上的方法就可以了
也可以用ShellExecuteEx,
用WaitForSingleObject等待参数中的hProcess，看一下msdn

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...");
}

谢谢各位的帮助，但使用CreateProcess的话参数怎么写呢？
ShellExecute(0, NULL, _T("aaaa.exe"), _T("123456"), NULL, SW_SHOWNORMAL)
其中的aaaa.exe是我调用别人的程序，123456是需要传入的参数，如果改为CreateProcess，应该怎么写呢？

我先试一下zhucde(【風間苍月】)(ＭＶＰ)大侠提供的方法，可以的话马上揭贴。

例子
CreateProcess("c:\\winnt\\aaaa.exe 123456", NULL,
NULL,NULL,FALSE,0,NULL,
NULL,&StartupInfo,&ProcessInfo)

WinExec
原型:
UINT WinExec(
  LPCSTR lpCmdLine,  // address of command line
  UINT uCmdShow      // window style for new application
);
用于十六位操作系统及兼容系统.
例如:
WinExec("notepad.exe f:\\调用程序.txt",SW_SHOW);
WinExec("notepad.exe ",SW_SHOW);
不同的参数用空格分开,故路径中不能有空格,而大部分程序默认是安装在"...\Program Files\...",如word,这极大的限制了WinExec的应用范围.
以上可不带路径:
1,程序所在目录.
2,当前路径.
3,系统目录,可以用GetSystemDirectory得到.
4,Windows 目录. 可以用TheGetWindowsDirectory得到.
5,在环境变量中设置的目录.ShellExecute
原型:
HINSTANCE ShellExecute(
    HWND hwnd,                   //父窗口句柄
    LPCTSTR lpOperation,         //操作,"open","print","explore"
    LPCTSTR lpFile,              //文件名,前面可加路径
    LPCTSTR lpParameters,        //参数
    LPCTSTR lpDirectory,         //默认文件夹
    INT nShowCmd                 //显示方式
);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 );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 );激活相关程序，发送EMAIL
ShellExecute(this->m_hWnd,"open","mailto:[email protected]","","", SW_SHOW );用系统打印机打印文档
ShellExecute(this->m_hWnd,"print","c:\abc.txt","","", SW_HIDE);lpParameters的用法示例:
一,建立一个可以接受参数的程序call.exe,添加如下代码:
BOOL CCallApp::InitInstance()
{
int n = __argc;
for(int i = 1 ; i < n ; i++)
AfxMessageBox(__targv[i]);
       //__targv[0]存储的是程序的文件名
...
}
二,Alt + F7的进行Project setting, Debug -> program argurments ->"1 2 3 4 5".
如果有多个参数,用空格分开.
三,运行.
四,执行ShellExecute(NULL,NULL,"f:\\call.exe","1 2 3 4 5",NULL,SW_SHOW);BOOL CreateProcess(
  LPCTSTR lpApplicationName,

  LPTSTR lpCommandLine,
  LPSECURITY_ATTRIBUTES lpProcessAttributes,
  LPSECURITY_ATTRIBUTES lpThreadAttributes,
  BOOL bInheritHandles,
  DWORD dwCreationFlags,
  LPVOID lpEnvironment,
  LPCTSTR lpCurrentDirectory,
  LPSTARTUPINFO lpStartupInfo,
  LPPROCESS_INFORMATION lpProcessInformation
);
STARTUPINFO   startupInfo;
memset(&startupInfo,0,sizeof(STARTUPINFO));
startupInfo.cb = sizeof(STARTUPINFO);示例:
//程序最启动时最大化
startupInfo.dwFlags |= STARTF_USESHOWWINDOW;
startupInfo.wShowWindow = SW_SHOWMAXIMIZED;

//运行....exe
PROCESS_INFORMATION ProcessInfo;
  BOOL bCreate = ::CreateProcess
        (
        "f:\\call.exe",// 1 2 3 4",
NULL,
NULL,
        NULL,
        FALSE,
        0,
        NULL,
        NULL,
        &startupInfo,
        &ProcessInfo); //等到call.exe执行完毕
WaitForSingleObject(ProcessInfo.hProcess,1000000);
MessageBox("调用程序结束!");
