首先下载duilib v1.1
打开后用vs2008 运行DuiLib.sln
解决方案窗口中你会发现7个项目分别为 360Safe,DuiLib,FlashDemo,GameDemo,ListDemo,QQDemo,TestApp1
右击360Safe项目 选择 设为启动项目 按Ctrl+F5运行程序, 然后弹出一个小窗口.
现在让我们来分析代码
int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE /*hPrevInstance*/, LPSTR /*lpCmdLine*/, int nCmdShow)
{
CPaintManagerUI::SetInstance(hInstance);//设置实例句柄
CPaintManagerUI::SetResourcePath(CPaintManagerUI::GetInstancePath() + _T("skin"));
CPaintManagerUI::SetResourceZip(_T("360SafeRes.zip"));//设置包含资源的压缩包,里面是图片和要用到的xml
HRESULT Hr = ::CoInitialize(NULL);//CoInitialize和CoUninitialize必须成对使用。
if( FAILED(Hr) ) return 0;//以上代码一般不变
C360SafeFrameWnd* pFrame = new C360SafeFrameWnd();//初始化实例
if( pFrame == NULL ) return 0;
pFrame->Create(NULL, _T("360安全卫士"), UI_WNDSTYLE_FRAME, 0L, 0, 0, 800, 572);//注册类和窗口
pFrame->CenterWindow();//把窗口放置在中间
::ShowWindow(*pFrame, SW_SHOW);
CPaintManagerUI::MessageLoop();//进入消息循环
::CoUninitialize();
return 0;
}
然后我们进入 类 C360SafeFrameWnd 中看看
class C360SafeFrameWnd : public CWindowWnd, public INotifyUI

}
