用VC写界面是件很痛苦的事情，到现在我也没有明明白白的搞明白许多细节。但界面很重要，非常重要。有时候在设计软件界面的时候，我就在想能不能构建一个lite版本的浏览器，用html脚本来构建一个具有丰富元素和容易扩张的界面。

安装过Visual Studio 2003/2005的肯定对下面的界面很熟悉：

当用spy++检查，发现：

是一个HTMLLITE窗口类，从名字就可以看出这是一个轻量级的html viewer。记得很早，在编译出ie 1.0的时候，我就在想用这个简易的源码可以写一个轻量级的html viewer，现在看来微软有人想到这个了。

好了，用dependy看一下导出函数列表：

_CchHtmlBreakLinesA@12
_CchHtmlBreakLinesW@12
_CchHtmlEscapeTextA@16
_CchHtmlEscapeTextW@16
DllMain
_FHtmlReplaceCtl@8
_FRegisterHtmlLiteClass@4
_FUnregisterHtmlLiteClass@4

我们需要就最后面的两个函数。

typedef VOID (WINAPI* FRegisterHtmlLiteClass)(HINSTANCE hInstance);

typedef VOID (WINAPI* FUnregisterHtmlLiteClass)(HISNTANCE hInstance);

//There is a sub inside the HTMLLITE.DLL with the Alias: _FRegisterHtmlLiteClass@4 typedef  VOID  (WINAPI  *PHTMLLITEPROC)(HINSTANCE  hInstance); //HTMLLITE Notification Message (HTMLLITE has a similar design to Windows Common Controls) typedef  struct  NMHTMLLITE  {     DWORD   hwndFrom;   //The Window Handle (hWnd) of the HTMLLITE control sending you this message.     DWORD   idFrom;     //If your HTMLLITE control is on a dialog, this member contains its Dialog ID.     DWORD   code;       //As defined below. As an example, this member will equal HTMLLITE_CODE_LEFTCLICK when a Link has been Left-clicked.     DWORD   linkid;     //When you create a Link with <a href=”…” linkid=xxx>, the linkid parameter is filled in this member.                         //.. allowing you to know which link has been clicked in your HTMLLITE control and then perform a specific action.     RECT    linkrc;     //This is a RECT structure which contains the coord’s and dimensions of the Link concerned. }  NMHTMLLITE,  *LPNMHTMLLITE; //HTMLLITE Notify Codes #define HTMLLITE_CODE_LEFTCLICK      1000 //A link has been clicked either via the Mouse or Spacebar key #define HTMLLITE_CODE_TABCYCLE       1001 //A link has received focus due to the Tab Cycle, or Keyboard Arrow Keys #define HTMLLITE_CODE_RIGHTCLICK     1003 //A link has been right-clicked, and already had focus #define HTMLLITE_CODE_MOUSEOVER      1004 //Mouse is over a link #define HTMLLITE_CODE_MOUSEHOVER     1005 //Mouse is hovering a link (~1 second = hover) #define HTMLLITE_CODE_MOUSEEXIT      1006 //Mouse has left a link’s rectangle #define WC_HTMLLITE                  TEXT(“HTMLLITE”) HMODULE  InitializeHtmllite(HINSTANCE  hApp) {     HMODULE  hLib  =  (HMODULE)LoadLibrary(TEXT(“htmllite.dll”));     PHTMLLITEPROC  Proc;     Proc  =  (PHTMLLITEPROC)GetProcAddress(hLib,  “_FRegisterHtmlLiteClass@4”);     Proc(hApp);     return  hLib; } void  DeleteHtmllite(HINSTANCE  hApp,  HMODULE  hHtmllite) {     PHTMLLITEPROC  Proc;     Proc  =  (PHTMLLITEPROC)GetProcAddress(hHtmllite,  “_FUnregisterHtmlLiteClass@4”);     Proc(hApp);     FreeLibrary(hHtmllite); }

创建完窗口后，就可以直接使用SetWindowText来设置窗口内容。比如：SetWindowText(TEXT(“

Hello HTMLLITE

不支持滚动条，只能支持有限的html语法。
