说明：  使用VB编程在遇到比较大的项目时经常需要进行模块的功能拆分。我们知道在VB中实现多线程比较麻烦，所有就考虑使用多进程来实现此功能。但是其中难免遇到多个进程中进行窗体的嵌套，如果使用findwindow或其他的API函数找窗口句柄成功率仅有50％的几率。所以考虑使用我所提供的方法。窗口嵌套成功率为100％。祝您成功。
(The use of VB programming in the face of relatively large projects often need to carry out the functions of modules split. We know that in VB to achieve multi-threading is too much trouble to consider the use of all the multi-process to achieve this functionality. But inevitably encounter a number of process of the nested form, if you use the FindWindow API function or other to find window handle the success rate of only 50 of probability. Therefore, I consider the use of methods provided. Nested window a success rate of 100. I wish you success.)
