中望CAD二次开发自定义菜单（C++）

在中望CAD中添加自定义菜单，一步一步来：

1.新建zrxobject项目，我命名为menuTest2。

2.引入菜单所需要的头文件，这一步很重要。我也是刚开始接触，查了很久，找到的代码都无法使用。后来在同事的帮助下搞定了，在此特别感谢邹建同学。记一下，分享给大家，也留个记录。

(1)右键单击项目，找到属性.

(2)点击打开属性，找到VC++目录，在包含目录和引用目录中加入中望CAD的安装目录，中望SDK目录下的inc文件夹以及目录下的lib-64文件夹,确定。

（3)在菜单栏上找到项目，添加类->MFC->TypeLib中的MFC类，点击添加。

（4）在打开的对话框中->可用的类型库，点击下拉列表，找到红箭头所指（最下面了哈），

从接口中选择和menu有关的接口，点红圈所示的地方，在右边就会看到相应的生成类，依次添加就好。点击完成

 

至此，准备工作就做完了。现在加代码，完整代码如下，读者可自行修改和添加。

生成，注意平台哈，32位还是64位，我是64的位。

找到menutest2.zrx。在中望CAD中加载，命令行输入DLGSAMPLE,ok，菜单出来了。注意：中望CAD要切换到经典模式，不然菜单出不来。这个问题折磨了我一早上，最后邹同学远程才搞定。
