NX Second Development - NX on the MFC read and write interface for Excel (OLE mode (COM component))

NX secondary development there are no relevant API function EXCAL read and write operations, the market there are many ways to implement such transfer UFUN KF, ODBC, OLE (COM component) and the like. Here I am using the OLE (COM components) way to do it, this method created on the VC, C ++ or C #, whether or VB way ideas are the same. First introduced to do with MFC, and then write a blog describes how to do the secondary development of templates in the wizard's NX.
NX Second Development - based NX NX development wizard template for Excel reads and writes https://ufun-nxopen.blog.csdn.net/article/details/88922238 (OLE manner (COM component)) (Look at this blog before, the current blog first reading).

EXCAL operation (a) open write

Reference example: https: //blog.csdn.net/ywx123_/article/details/77074038
This is another CSDN bloggers to write, I do also refer to his example, and then thank the bloggers.

Create a new MFC project

Click Next.

Select dialog-based

Direct Done, come in below

The first point of the project, right property, change to multi-byte.

First nothing moving, compile the code. Default can not see through.
Then project, right-class wizard.

The following pop-up window

Click Add Class - MFC class type library

Pop up

We switched to a file, click Add.

To add a file found here is your computer to upload EXCAL.exe the program file.
If you do not know how to find it, there is a method, go to the Start menu to find your EXCAL shortcut, then right click, open the file location.

This found.

下面在回到MFC项目里面，我们选中这个文件。
添加进来之后，如图所示。

左侧为EXCAL给出的接口，我们来选择一些需要的添加进来。
我们就先添加这七个，后续有其他需求在添加其他的。(先在左侧接口里选中一个，点中间的>就能添加到右侧里生成的类里，不想要就在点中间的<撤退回去。)

然后我们点完成，点确定。就看到头文件自动添加进来了。

我们点击新增进来的EXCAL每个头文件，都把第一行的那句注释掉。

都注释完之后，我们在#include "stdafx.h"里添加EXCAL头文件，

然后编译代码，出现如下报错问题。这时我们双击这个错误，跳到对应的代码那里。

有问题的位置如下

我们需要在DialogBox前面加上一个 _ 下划线。再去编译就通过了。别问我为什么，我答不上来，你照着搞就是了，别人就是这么搞的。

好的，到这里我们这个项目环境就算搭建完成了。
下面可以写代码了。
点击MFC那个对话框界面，双击确定。在里面写代码。

代码如下：打开EXCAL，写入内容。

  1     //1.创建基本对象
  2     CApplication App;  //创建应用程序实例
  3     CWorkbooks Books;  //工作簿，多个Excel文件

 97     range.ReleaseDispatch();
 98     sheet.ReleaseDispatch();
 99     sheets.ReleaseDispatch();
100     Book.ReleaseDispatch();
101     Books.ReleaseDispatch();
102     App.ReleaseDispatch();

编译后，我们点调试-开始执行。

点确定，自动打开了EXCAL，并写入了内容。EXCAL自动保存在了你这个项目的当前文件夹里。

就写到这里了，好多我也没有用过，回头用到了再去研究。其他的相关内容大家参考下面这些大神们的博客吧。
