前两天为公司改程序，其中有一部分是要打印出报表。原来的程序是调用VB写的一个程序。那个程序用VBA方式实现的，在一个空的WORD表格模板里填入数据，让WORD去打印，效果还可以，就是速度很慢。但是这次，上次写代码的人已经不在这里了，我并不想去学VBA，无奈之下找到了一个Rob.A Fraydl写的打印类示例，但是里面没有我要的功能，只是示范了怎么去打印。于是自己重新的封装了一下，基本算是合格了。(two days ago for the company to change procedures, which are in part to print out statements. The original procedure was called VB write a procedure. VBA procedure that was achieved in an empty template forms WORD Lane Enter data, Let Word to print, the results were, and that is very slow. However, this time, the last person to write the code has been going on here, I do not want to go to school VBA, In desperation to find a Rob.A Fraydl write Print category example, but there's no I want function, the model is how to print. His own re-packaging it, and basically considered a pass.)
