如何将现有的代码/位图分配给MFC

Question

因此，我编写了一个模拟骰子游戏的程序，就像骰子游戏一样。我想把这个正常的控制台应用程序变成基于对话框的MFC。所以我会创建一个标签为“Roll”的按钮，并且窗口会显示正在滚动的两个模子。 以下是我为吊app应用程序编写的代码。它完美的工作，但我很困惑如何将代码分配给按钮，以及如何将模具面分配给其各自的位图。我感谢帮助！

您需要添加一个事件处理程序来处理按钮控件的鼠标点击。比方说，您已经在对话框中添加了一个按钮，并为其指定资源ID IDC_ROLLDICE。要添加事件处理程序，请右键单击您添加的按钮并选择“添加事件处理程序”。一个窗口会弹出，要求你填写一些信息。在“消息类型”下，请确保已选择BN_CLICKED。这将告诉MFC消息调度程序，您对该特定事件感兴趣。在标有“函数处理程序名称”的字段中给它起个名字。一旦你添加了所有的信息，点击“添加和编辑”。这会将一个成员函数添加到CDialog派生类和消息映射中的一个条目，以确保它被调用。它应该看起来像下面这样

void CMyDialog::OnBnClickedRolldice() 
{ 
// TODO: Add your control notification handler code here 
} 

现在，只要你点击按钮，MFC会调用OnBnClickedRolldice。只需开始添加代码，将骰子滚动到该成员函数中，并根据需要添加成员变量。

基本上你会通过成员变量和函数将整个应用程序移动到CDialog派生类中。
