Win32API Wizzard97 PropSheet_SetWizButtons 不起作用

Question

我刚刚学习使用 C 的 Win32 API，我需要向我的应用程序添加向导。这是我第一次这样做，所以我确信这段代码有很多问题。我一直在研究 MSDN 网站，并且我的实现基于我对那里提供的示例和解释的解释。我在这里缺少什么？向导按钮没有改变，并且单击向导最后一页上的“下一步”不会执行任何操作。关闭向导的唯一方法是按取消按钮。我迷路了。非常感谢任何帮助！

Answer 1

正如Raymond Chen所说：hDlg是“属性表的句柄”。

对于向导本身的句柄，请致电

GetParent(hwnd)

。
