很多基于对话框的程序都有一个启动画面，那么如何为自己的对话框程序也加一个这样的画面呢？其实VC++开发环境中有一个现成的 Splash Screen 组件，用这个组件很容易实现基于框架类（也就是CMainFrame）的程序的启动画面，那么如果是对话框程序，没有框架类怎么办呢？所以这个组件功能不是想象的那么强。要实现基于对话框应用程序的启动画面必须另辟蹊径。这里提供一个可重用代码例子，一步一步教你实现每一个细节。利用一个定制的C++类：CSplashWnd，增强原来的 Splash Screen 组件功能。它不但可以在用于具有CMainFrame的程序，同时也可以用于基于对话框应用的程序。-many of the procedures based on the dialog has launched a picture for themselves as to how the dialog procedures were also such a picture? In fact, VC environment with a ready-made Splash Screen components, the components used easily framework based category (that is, CMainFrame) of the commencement of proceedings picture, then if the dialog procedure is not like the framework of how to do? Therefore, this component function is not so strong as imagined. To achieve based on the application's dialog screens must choose another road. Here provide a reusable code examples, step by step teach you realize every detail. Using a customized Category C : CSplashWnd, enhance the original Splash Screen functional components. It can be used not only with CMainFrame procedures, and also can be used
