例：
aaa.txt 位于G盘根目录
格式为：
字段名1,字段名2
000,2222
111,2233
库:db1.mdb,表Table1,字段：字段名1,字段名2
代码：
Dim db As Database, tbl As TableDef
Set db = DBEngine.OpenDatabase("g:\db1.mdb") '打开数据库
Set tbl = db.CreateTableDef("temp") '创建一个临时的文本链接表
tbl.Connect = "text;database=g:\" 'TXT文件所在的目录
tbl.SourceTableName = "aaa#txt" 'TXT文件的名称
db.TableDefs.Append tbl '将表加入到数据库中
db.Execute "insert into table1 select * from temp"
db.TableDefs.Delete tbl.Name '删除temp链接表
db.Close: Set db = Nothing '关闭数据对象
If Err = 0 Then
MsgBox "导入成功! "
Else
MsgBox "错误" & Err
Exit Sub
End If
--------------------
以上代码，VB6.0测试通过
首先在程序目录建立fff.mdb数据库，最好你自己建立。然后在数据库建立一个数据表，比如“数据”，在其中添加三个字段：ID、数据1、数据2。
