.NET中怎么记录软件的操作日志
其实有很多种方法的，例如用log4net就可以实现的，再配置文件设一些参数，在需要记录日志的地方调用就行
请教高手，如何用vb实现“使用日志”？
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
vb怎么记录日志文件
'记录数据
open "c:\log.txt" For Output As #2 ’写文件
Print #2, "用户：" USERNAME "操作时间：" date " " time "操作项目：登陆系统！"
Close #2
' 查看数据,并且在list1中一条条显示出来
Open "c:\log.txt" For Input As #1 ’读文件
Dim i As String
Do While Not EOF(1)
Line Input #1, i '逐行把1号文件读入到变量i
list1.AddItem i
Loop
Close #1
