Everything Will Flow

MFC中PreTranslateMessage是GetMessage(...)函数的下一级操作，即GetMessage(...)从消息队列中获取消息后，交由PreTranslateMessage（）处理，若其返回FALSE则再交给TranslateMessage和 DispatchMessage处理（进入WindowProc）；
如果用SendMessage, 则消息直接交到WindowProc处理，所以GetMessage不会取得SendMessage的消息，当然PreTranslateMessage也就不会被调用。
如果用PostMessage,则消息进入消息队列，由GetMessage取得，PreTranslateMessage就有机会进行处理。

(1) 如何建立自动增长字段?
简短回答：声明为 INTEGER PRIMARY KEY 的列将会自动增长。
长一点的答案： 如果你声明表的一列为 INTEGER PRIMARY KEY，那么， 每当你在该列上插入一NULL值时， NULL自动被转换为一个比该列中最大值大1的一个整数，如果表是空的， 将会是1。 (如果是最大可能的主键 9223372036854775807，那个，将键值将是随机未使用的数。） 如，有下列表：
CREATE TABLE t1(
  a INTEGER PRIMARY KEY,
  b INTEGER
);

//------------------------------------------
bool RssTreeView::LoadXmlToTree(LPCWSTR xmlFileName)
{
 if(PathFileExists(xmlFileName) == TRUE)
 {
  if ( SUCCEEDED(CoInitialize(NULL)) )
  {
   MSXML2::IXMLDOMDocument *pDoc;
   if ( SUCCEEDED (CoCreateInstance(MSXML2::CLSID_DOMDocument,
              NULL,
              CLSCTX_INPROC_SERVER,
              MSXML2::IID_IXMLDOMDocument,
              reinterpret_cast<void**>(&pDoc))))
   {
    //
    // Tell the "doc" that we're not going to load asynchronously.
    //
    if ( SUCCEEDED(pDoc->put_async(VARIANT_FALSE)) )
    {
     CComVariant vFile(RssDefaultNewsPath);
     VARIANT_BOOL vBool;
     pDoc->load(vFile,&vBool);
     if ( vBool == VARIANT_TRUE )
     {
      MSXML2::IXMLDOMNodePtr pRootNode;
      pDoc->selectSingleNode(_T("root"), &pRootNode); //取得根節點
      if(pRootNode == NULL)
       return  false;
