请问VB能否在程序运行过程中将变量的值赋给数据库的字段? - VB6论坛 - 编程论坛

谁说ADO只能读取文本框的东西了? 那是ADODC控件,而不是ADO对象,况且ADODC也可以赋值啊,ADODC也不只有用绑定控件这种笨办法,大可以这样啊:Text1.Text=ADODC1.RecordSet!FiledName,不用绑定的,绑定最笨了
另外
Execute方法知道吗?动态生成SQL语句,比如:
Dim TxtSql as String
Dim a as String
TxtSql="UpDate TableName Set FiledName='" & a & "'"
'这样就已经生成了一条Sql语句,然后用Execute方法提交运行


要是看不懂的话,先去看看ADO的资料,这是最好的办法

 

三断笛,你好!这是我的演示程序,请看看为什么不能将数据写入到数据库?
请帮忙修改一下,谢谢!
Private Sub Cmdtest_Click()        '测试按钮
Dim a As String
Dim b As String
Dim c As String
cs_num = 9
lz_data = 999
bxl_data = 99      
'以上是演示用的数据
txtFields(0) = cs_num
txtFields(1) = lz_data
txtFields(2) = bxl_data
a = txtFields(0)
b = txtFields(1)
c = txtFields(2)
