                        今天编写了两个函数分别为"ExecuteCmdA"和"ExecuteCmdB",区别如下: A:可设置执行目录、可设置超时退出,不可隐藏命令行窗口,与管道通信读取执行结果。B:可隐藏命令行窗口,不可设置执行目录、不可设置超时退出,将执行结果写入到本地文件后再读取。函数名称: ExecuteCmdA执行CMD并返回结果 参数定义: CommandLine 字符串型:执行的指令CurrentDir 字符串型:设置执行目录,为空则为当前目录TimeOut 整数型:超时时间,单位为毫秒,0为不判断超时,否则命令行若执行超过设定时间则强制退出执行 返回值: 字符串型:返回执行结果,若失败返回错误信息或空。 调用例子: TracePrint ExecuteCmdA("dir", "C:", 10000) '获取C盘目录,设置超时为10000毫秒 函数名称: ExecuteCmdB 执行CMD并返回结果 参数定义: CommandLine 字符串型:执行的指令 IsVisble 整数型:是否显示命令行窗口,为1代表显示,其他数字为隐藏。 返回值: 字符串型:返回执行结果。 调用例子: TracePrint ExecuteCmdB("ping bbs.anjian.com", 0) '测试连接按键论坛,隐藏命令行窗口
