为了让更多的朋友能够让自己的程序使用上金山卫士的界面库，现将创建界面库的过程用文字说明，希望可以帮助到各位。如果觉得过程麻烦，也可以直接下载创建后的完整代码。
 
 
基本要求：安装WTL，下载地址：http://wtl.sourceforge.net/。下载解压后，到解压目录的AppWiz子目录下运行setup80.js（对应VS2005）即可安装完毕。
 
       这是补充：要告诉VS2005编译器WTL下的头文件的位置。
 
      工具->选项->VC++目录 在包含中加入    D:\WTL80_7161_Final\include
 
第一步、复制卫士界面库必要的文件
 
在VS2005中，单击菜单“文件”->“新建”->“项目”，在新建对话框中选择项目类型为“WTL”，模版只有一个“ATL/WTL Application Wizard”，选中它并在下方的编辑框中输入项目名和项目位置，这里假设创建后的目录为H:\MyProject\test。单击“确定”，在出现的向导中选择“下一步”，选择“Dialog Based”，并单击“Finish”按钮。

在H:\MyProject\test\test下创建publish文件夹，然后到http://code.ijinshan.com下载金山卫士源代码，将其解压到某个目录，打开其子目录pcmanager\src\publish，将其下的bkres、bkwin、tinyxml和wtlhelper复制到H:\MyProject\test\test\publish下。

第二步、添加包含目录

在VS2005的“解决方案资源管理器”中，右键点击test项目（注意是项目而不是解决方案），选择属性。

在出现的“test属性页”对话框中，选择左边的“配置属性”->“C/C++”->“常规”项，在右边的“附加包含目录”中输入publish，点击“确定”保存设置。

 第三步、将Bkres、TinyXML加入项目中

在“解决方案资源管理器”中，右键点击“Resource Files”，选择“添加”->“现有项”，定位到publish\bkres目录下，将bkres.rc添加进项目。

然后再在test项目上点击右键，选择“添加”->“新建筛选器”，创建名为publish的筛选器，再在publish下创建TinyXML筛选器（创建筛选器只是为了分类方便，这一步可以略过，文件添加到任何一个筛选器中）。接下来用和以上相同的添加现有项的方法将publish\tinyxml下的所有文件添加到TinyXML筛选器下。

 

第四步、去除TinyXML预编译头设置

展开publish\TinyXML筛选器，右键点击一个cpp文件，选择属性。

 

点击左边的“配置属性”->“C/C++”->“预编译头”，将右边的“创建/使用预编译头”选项设置为“不使用预编译头”，点击“确定”。

 

 

 

 
对TinyXML筛选器下所有cpp文件都执行这一步。
 
 
第五步，添加必要的代码
 
主要是替换默认生成的WTL基本对话框的代码，转而使用调用卫士界面库的代码，并且加入卫士界面库必需的定义XML相关文件和图片资源。此处为了方便起见，将代码打包，各位可以直接从附件中下载，将文件替换掉原先创建项目时自动生成的代码，然后将新增的bkwinres.h以及bkwinres.rc2添加到项目中即可。
 
这里可以看到_tMain函数中的
 
CMainDlg dlgMain; 
 dlgMain.DoModal(); 
 
而构建CMainDlg的方法是:
 
 
class CMainDlg  : public CBkDialogImpl<CMainDlg> 
                , public CWHRoundRectFrameHelper<CMainDlg> 
{ 
public: 
    CMainDlg():CBkDialogImpl<CMainDlg>(IDR_BK_MAIN_DIALOG) 
    { 
    } 
 
    BK_NOTIFY_MAP(IDC_RICHVIEW_WIN) 
        BK_NOTIFY_ID_COMMAND(IDC_BTN_CLOSE, OnBtnClose) 
        BK_NOTIFY_ID_COMMAND(IDC_BTN_MIN, OnMinBtnClick) 
    BK_NOTIFY_MAP_END() 
 
    BEGIN_MSG_MAP(CMainDlg) 
        MSG_BK_NOTIFY(IDC_RICHVIEW_WIN) 
        CHAIN_MSG_MAP(CBkDialogImpl<CMainDlg>) 
        CHAIN_MSG_MAP(CWHRoundRectFrameHelper<CMainDlg>) 
        MSG_WM_SYSCOMMAND(OnCommand) 
        MSG_WM_INITDIALOG(OnInitDialog) 
    END_MSG_MAP() 
 
protected: 
    LRESULT OnCommand(UINT wParam, CPoint point); 
    BOOL OnInitDialog(CWindow wndFocus, LPARAM lInitParam); 
    void OnBtnClose(); 
    void OnMinBtnClick(); 
}; 
 
CBkDialogImpl  CWHRoundRectFrameHelper是金山开源软件中自定义的类,我们在看它们的实现.

        rcClient.OffsetRect(- rcWindow.TopLeft());

        pT->SetWindowRgn(rgnWindow);
