<p>新手问题，别笑话我噢</p>
<p>下面这一串代码定义的是什么啊？作用是什么</p>
<p>我在项目的模块里看到的</p>
<p>Public Const HH_DISPLAY_TOC = &amp;H1</p>
<p>Public Const HH_DISPLAY_INDEX = &amp;H2</p>
<p>Public Const HH_DISPLAY_SEARCH = &amp;H3</p>
<p>Public Const HH_DISPLAY_TOPIC = &amp;H0</p>
<p>Public Const HH_SET_WIN_TYPE = &amp;H4</p>
<p>Public Const HH_GET_WIN_TYPE = &amp;H5</p>
<p>Public Const HH_GET_WIN_HANDLE = &amp;H6</p>
<p>Public Const HH_DISPLAY_TEXT_POPUP = &amp;HE</p>
<p>Public Const HH_HELP_CONTEXT = &amp;HF</p>
<p>Public Const HH_TP_HELP_CONTEXTMENU = &amp;H10</p>
<p>Public Const HH_TP_HELP_WM_HELP = &amp;H11</p>

<p>这些都是常量,其具体作用在MSDN里有说明.</p>
