That's it! . Inserting the pumpwaitingmessages into the lengthy function is
a easiest way to solve the problem.
void MyDialog::LenghtyFunction(){
    while (lenghtyProcessing){
        MSG msg;
        if (PeekMessage(&msg, 0, 0, 0, PM_REMOVE)) {
            TranslateMessage(&msg);
            DispatchMessage(&msg);
        }
        // process
    }
}

Thank you all, guys.
