c++ - 如何将现有代码/位图分配给 MFC

Question

所以我写了一个模拟骰子游戏的程序，几乎就像掷骰子游戏一样。我想把这个普通的控制台应用程序变成一个基于对话的 MFC。所以我会创建一个标有“Roll”的按钮，窗口会显示两个正在滚动的骰子。 这是我的吊顶应用程序代码。它工作得很好，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。感谢您的帮助!

您需要添加事件处理程序来处理按钮控件的鼠标单击。假设您向对话框添加了一个按钮并为其指定了资源 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”。将弹出一个窗口，要求您填写一些信息。在“消息类型”下，确保选择了 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”的字段中为其命名。添加完所有这些信息后，单击“添加和编辑”。这将向您的 CDialog 派生类添加一个成员函数，并在消息映射中添加一个条目以确保它被调用。它应该如下所示

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

现在，无论何时单击按钮，MFC 都会调用 OnBnClickedRolldice。只需开始添加您的代码以将骰子掷入该成员函数并根据需要添加成员变量。

基本上，您将通过成员变量和函数将整个应用程序移动到 CDialog 派生类中。
