miniGUI1.6 IP控件自定义 续篇，解决了只能保存一个IP地址的问题
来源：互联网 发布：客户数据分析报告范文 编辑：程序博客网 时间：2024/05/20 22:30
上一篇的IP控件存在一个大的问题，就是创建多个控件的时候，每个控件的IP值都会是一样的。原因是我只保存了四个变量，就是一个IP地址。
这篇文章里就已经解决了这问题， 主要是利用minigui 给控件预留的两个附加值， 可以用GetWindowAdditionalData SetWindowAdditionalData GetWindowAdditionalData2 SetWindowAdditionalData2 来访问，参数第一个是窗口，第二个是DWORD值，一般都是结构体的地址。

使用方法还是很简单哈，直接调用 CreateIPSpinBoxWindow函数就可以，参数没有类名了，其他跟CreateWindow一样。
结构体就是保存IP值的关键数据。 其实这个还有个问题就是如果你创建多个IP控件大小不一样的时候，你会发现数据也会存在异常，原因跟保存IP值是一样的，这里就不解决了，有需要的可以自己去改就是。 也很简单，直接把4个RECT 加到IPDATA里面，然后在初始化的时候赋值，在要用的时候取出来就可以了。
至此，改IP控件已经实现了一个IP控件应有的功能，就到此结束了。
用鼠标点击要修改的字节，可以用右边的spin按钮改变IP值，也可以输入。
