There isn't any one specific function for that.  You will have to find the
window handle manually, using EnumWindows() and GetWindowProcessThreadId().

I would suggest you use CreateProcess() instead of ShellExecuteEx().
ShellExecute() does not return the ID of the spawned process.
CreateProcess() does.  You need that ID so that you have something to
compare with GetWindowThreadProcessId().

    struct sWndInfo
    {
        HWND hWnd;
        DWORD dwProcessId;
    };

    BOOL CALLBACK FindMainWindow(HWND hwnd, LPARAM lParam)
    {
        sWndInfo *pInfo = (sWndInfo*) lParam;

        DWORD dwProcessId;
        GetWindowThreadProcessId(hwnd, &dwProcessId);

        if( dwProcessId == pInfo->dwProcessId )
        {
            if( hwnd matches some criteria )
            {
                pInfo->hWnd = hwnd;
                return FALSE;
            }
        }


        return TRUE;
    }

    {
        AnsiString CmdLine = AnsiQuotedStr(sexe, '"') + " "  + sprm;

        STARTUPINFO si = {0};
        PROCESS_INFORMATION pi = {0};

        si.cb = sizeof(si);
        si.dwFlags = STARTF_USESHOWWINDOW;
        si.wShowWindow = SW_SHOWNORMAL;

        if( CreateProcess(NULL, CmdLine.c_str(), NULL, NULL, FALSE, 0, NULL,
spth.c_str(), &si, &pi);
        {
            WaitForInputIdle(pi.hProcess, INFINITE);
            CloseHandle(pi.hThread);
            CloseHandle(pi.hProcess);

            sWndInfo Info = {0};
            Info.dwProcessId = pi.dwProcessId;
            EnumWindows((WNDENUMPROC) FindMainWindow, (LPARAM) &Info);

            if( Info.hWnd )
                // use Info.hWnd as needed...
        }
    }


Even better, the lpStartupInfo parameter of CreateProcess() allows you to
pass in the desired position and size directly:

    {
        AnsiString CmdLine = AnsiQuotedStr(sexe, '"') + " "  + sprm;

        STARTUPINFO si = {0};
        PROCESS_INFORMATION pi = {0};

        si.cb = sizeof(si);
        si.dwFlags = STARTF_USESHOWWINDOW;
        si.dwX = ...;
        si.dwY = ...;
        si.dwXSize = ...;
        si.dwYSize = ...;
        si.wShowWindow = SW_SHOWNORMAL | STARTF_USEPOSITION |
STARTF_USESIZE;

        if( CreateProcess(NULL, CmdLine.c_str(), NULL, NULL, FALSE, 0, NULL,
spth.c_str(), &si, &pi);
        {
            CloseHandle(pi.hThread);
            CloseHandle(pi.hProcess);
        }
    }
