BOOL PASCAL CWnd::WalkPreTranslateTree(HWND hWndStop, MSG* pMsg)
{
ASSERT(hWndStop == NULL || ::IsWindow(hWndStop));
ASSERT(pMsg != NULL);
// walk from the target window up to the hWndStop window checking
// if any window wants to translate this message
for (HWND hWnd = pMsg->hwnd; hWnd != NULL; hWnd = ::GetParent(hWnd))
{
CWnd* pWnd = CWnd::FromHandlePermanent(hWnd);
if (pWnd != NULL)
{
// target window is a C++ window
if (pWnd->PreTranslateMessage(pMsg))
return TRUE; // trapped by target window (eg: accelerators)
}
// got to hWndStop window without interest
if (hWnd == hWndStop)
break;
}
return FALSE; // no special processing
}
{
ASSERT(hWndStop == NULL || ::IsWindow(hWndStop));
ASSERT(pMsg != NULL);
// walk from the target window up to the hWndStop window checking
// if any window wants to translate this message
for (HWND hWnd = pMsg->hwnd; hWnd != NULL; hWnd = ::GetParent(hWnd))

如何调用qt编写activex控件的函数
loadlibrary()和getprocaddress()用于非activex的链接库，你可以接着调用函数试试看
