ShellExecute调用程序后如何取得该程序的主窗口（不用FindWindow）

Question

CString szApp = "rundll32.exe";
CString szParam = "shell32.dll,Control_RunDLL inetcpl.cpl,,3";
SHELLEXECUTEINFO ShExecInfo = {0};
ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
ShExecInfo.hwnd = m_hWnd;
ShExecInfo.lpVerb = NULL;
ShExecInfo.lpFile = szApp;             
ShExecInfo.lpParameters = szParam;     
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_SHOWNA;
ShExecInfo.hInstApp = AfxGetInstanceHandle();       
ShellExecuteEx(&ShExecInfo); CWnd* pWnd = NULL;
while(pWnd == NULL)
{
     pWnd = FindWindow(NULL,"Internet ÊôÐÔ");
}
MSG msg;
while (!g_bWait)
{
     if (::PeekMessage(&msg,NULL,0,2000,PM_REMOVE))
     {
::TranslateMessage(&msg);
if((msg.message == WM_LBUTTONDOWN) || 
                  (msg.message ==  WM_NCLBUTTONDBLCLK)||
                  (msg.message == WM_NCLBUTTONDOWN) )
{
    if(::IsWindow(pWnd ->GetSafeHwnd()))
pWnd ->BringWindowToTop();
}
else
{
      if(msg.message == WM_PAINT)
    {
        if(::IsWindow(pWnd ->GetSafeHwnd()))
            pWnd ->BringWindowToTop();
::DispatchMessage(&msg);
                      }
}
              }
}
   如何能不用FindWindow，通过ShExecInfo取得pWnd;

Answer 1

shellExecute返回进程的句柄，你可以用它

Answer 2

那反过来是否可以，通过窗口是否可以取得进程句柄？
这样可以使用GetWindwo(GW_CHILD)进行筛选

Answer 3

通过窗口是否可以取得进程句柄:
GetWindowThreadProcessId

Answer 4

STARTUPINFO si;
ZeroMemory(&si,sizeof(si));
si.cb = sizeof(si);
si.wShowWindow = SW_SHOWNA;
si.dwFlags = STARTF_USESHOWWINDOW|STARTF_USESTDHANDLES;
    PROCESS_INFORMATION pi;
    if (!CreateProcess(NULL,"rundll32.exe shell32.dll,Control_RunDLL inetcpl.cpl,,3",
        NULL,NULL,FALSE,0,NULL,NULL,&si,&pi)) 
    return;    CloseHandle(pi.hThread);
    CloseHandle(pi.hProcess);
//m_hInternet = NULL;
m_hInternet = NULL;
while(m_hInternet == NULL)
EnumWindows((WNDENUMPROC)EnumWinProc,(LPARAM)pi.dwProcessId);
    
CString str;
MSG msg;
while (::IsWindow(m_hInternet))
{
if (::PeekMessage(&msg,NULL,0,2000,PM_REMOVE))
{
::TranslateMessage(&msg);
if((msg.message == WM_LBUTTONDOWN) || (msg.message == WM_NCLBUTTONDBLCLK)||
(msg.message == WM_NCLBUTTONDOWN) )
{
if(::IsWindow(m_hInternet))
::BringWindowToTop(m_hInternet);
}
else
{
if(msg.message == WM_PAINT)
{
if(::IsWindow(m_hInternet))
::BringWindowToTop(m_hInternet);
}
::DispatchMessage(&msg);
}
}
}

Answer 5

BOOL CRegistInternet::EnumWinProc(HWND hwnd,LPARAM lParam)
{
DWORD nID = 0;
GetWindowThreadProcessId(hwnd,&nID);
if((DWORD)lParam == nID)
{
m_hInternet = hwnd;
return FALSE;
}
return TRUE;
}
