在插件中为 WM_NCHITTEST 返回 HTTRANSPARENT

Question

我怎样才能获得一个插件来使程序让我的点击穿过窗口？我听说我必须为 WM_NCHITTEST 返回 HTTRANSPARENT。是否可以通过挂钩来做到这一点？这是我所掌握的：

LRESULT CALLBACK myHook(int nCode, WPARAM wParam, LPARAM lParam) 
{
    CWPSTRUCT* pwp = (CWPSTRUCT*)lParam;

    if (nCode >= 0)
    {
    if (pwp->message==WM_NCHITTEST)
        MessageBox(NULL, TEXT("NCHITTEST has been receieved."), TEXT("NCHITTEST"), MB_ICONINFORMATION);                
    }

    return CallNextHookEx(hHook,nCode,wParam,lParam);
}
