vb实时错误3021
请帮我看看代码错哪里?挺乱的Public combo As String
Private Sub Command1_Click(Index As Integer)

rs.Open "Select * from zhuti", cn, adOpenStatic, adLockReadOnly
rs1.Open "Select * from keti", cn, adOpenStatic, adLockReadOnly

错误字段:level2 = rs3("degree1")
depart2 = rs3("bumen1")
--------------------编程问答-------------------- 赋值以前要判断记录集是否有数据返回 --------------------编程问答-------------------- 那要怎么写代码呢？ --------------------编程问答-------------------- 错误提示在哪一句处?? --------------------编程问答-------------------- level2 = rs3("degree1") --------------------编程问答-------------------- 如果确是因为没有记录集返回造成的错误:
if not rs3.eof then
level2 = rs3("degree1")
depart2 = rs3("bumen1")
...
end if --------------------编程问答-------------------- if (not rs3.eof) and (not rs3.bof) then
level2 = rs3("degree1")
depart2 = rs3("bumen1")
'.......
end if --------------------编程问答-------------------- 新记录集尚未迁移，5 楼代码足矣。 --------------------编程问答-------------------- 如果我这么写了还是错呢？会不会有可能没连上数据库？ --------------------编程问答-------------------- 已经没有那个错误了，可按下按键后一点反应都没有，是我循环语句错了吗？ --------------------编程问答-------------------- level1 = rs2("degree1")
语句没错,就说明连接是成功的!
....
如果我这么写了还是错呢？会不会有可能没连上数据库？
你不试怎么知道!!!!! --------------------编程问答-------------------- If rs3.BOF And rs3.EOF Then '如果为空
level2 = 0
Else '如果不为空
level2 = rs3("degree1")
End If
我这样写现在不报错了，可是按按键怎么什么反应都没有？代码哪里错了 --------------------编程问答-------------------- lz要干嘛？
补充：VB , 数据库(包含打印，安装，报表)
