VB把SWF转换成EXE，存放SWF文件在EXE文件中的偏移,在这里是用固定点查找法。EXEtoSWF2 = False 首选等于假，等到最后成功后再等于真，这一段先检测是否是EXE格式的Flash文件，是然后转化为SWF。EXE2SWF(Flash EXE文件转SWF文件工具)，使用Flash Player生成的EXE文件，格式很简单： 　　开始是 Flash Player播放器的EXE文件内容，接着是 SWF文件内容，再是 4字节的标志，最后 4字节是SWF文件的大校目前常见的Flash EXE文件,就4.0,5.0,6.0等几个版本,其大小分别是： 　　flash player 3.0 r8 24000H 　　Flash Player 4.0 r7 46000H 　　Flash Player 4.0 r4 47000H 　　Flash Player 5.0 r30 5c000H 　　Flash Player 6.0 r21 c8000H 　　Adobe Flash Player 9.0 r16 2A3688H 　　如果还有其它版本的Flash Player，你只要在代码中添加Flash Player的大小，就可以支持。

vc++枚举窗口实例：获取显示在最顶层的窗口标题，将显示枚举到的窗口类名和窗口标题，操作简单，只需要点击窗口中的“枚举所有顶层窗口”即可，运行的界面效果如演示截图所示。

我们设计的异步电机变频调速器以TMS320F28035芯片为控制核心，通过输出三相PWM波控制智能功率模块IPM驱动三相异步电机。我们使用空间矢量SVPWM算法，并对其进行了优化。采用异步电机无传感器测速算法省去了昂贵的光电编码器，大大节省了成本。同时开创性的研发了自动根据运行环境调节的自适应变频算法，使我们的变频调速器可以在电网条件恶劣的乡村山区工作，由此该变频器已被一家民用水泵生产企业预订。(We design the asynchronous motor frequency conversion governor with TMS320F28035 chip as the control core, and output three-phase PWM wave to control the intelligent power module IPM to drive the three-phase asynchronous motor. We use space vector SVPWM algorithm and optimize it. The sensorless speed measurement algorithm of asynchronous motor eliminates the expensive photoelectric encoder and greatly saves the cost. At the same time, pioneering research automatic conversion algorithm based on adaptive adjustment of the operating environment, we can make VVVF in power grid conditions of rural area, thus the inverter has been a civil pump manufacturer reservation.)
