说明：  我自己写的 将动态 字符串解析到CTreeCtrl。以前是为了 写道数据库，不用ＸＭＬ，为了不麻烦。就 用 VC 写了一个 这个 这个，希望大家可以用到(I wrote it myself dynamic string parsing to CTreeCtrl. Previously wrote to the database, not XML, in order not to trouble. On the VC was a um, hope that we can use!)

SAP5源代码有助于研究生学习和工作人员工作(SAP5 source code)

VB打印条形码的测试程序，不包括其它的功能，只是演示如何将条码打印出来，功能单一，不过容易理解，VB6.0打印条形码无思路的可参考。 (VB test program print bar codes do not include other functions, but demonstrates how to print out barcodes, single function, but it is easy to understand, VB6.0 print barcodes without thinking can be found.)
