自动在log目录中,生成日志文件,文件命名用年月日定义,如20100119_log.log。
在日志文件中,每行记录一个时间点的运行内容,时间点的精度应该达到毫秒。
Dim sw As StreamWriter = New StreamWriter(“c:\xxxxx.log”, True) 'true是指以追加的方式打开指定文件
For i = 0 To j
temp = i.ToString
sw.WriteLine(temp)
sw.Flush()
Next
sw.Close()
sw = Nothing
缺少运行库
装上.NETframework
和带上引用的插件(工程属性那有个引用页)
吧

很多种方法,最常用的一是用文本文件或数据库记录,二是调用API函数直接写入系统日志或应用程序日志
