咨询下各位大老，VB访问mdb数据库最多多少个啊，我的一个表里有140个字段。
怎么我一点"下一条"程序就卡死了
Set RS = New ADODB.Recordset '新建一个recordset
Set lsRS = New ADODB.Recordset
RS.CursorType = adOpenStatic
RS.CursorLocation = adUseClient
RS.LockType = adLockPessimistic
RS.Open "SELECT * FROM xb  ORDER BY 项目名称 ASC", Con
lsRS.CursorType = adOpenStatic
lsRS.CursorLocation = adUseClient
lsRS.LockType = adLockPessimistic
lsRS.Open "SELECT * FROM xb1", Con
For i = 0 To 136
    Set Text1(i).DataSource = RS
    Text1(i).Locked = True
Next
Text1(0).DataField = "项目名称"
Text1(1).DataField = "名称"
Text1(2).DataField = "型号"
Text1(3).DataField = "制造编号"
Text1(4).DataField = "制造厂家"
Text1(5).DataField = "额定电压G"
Text1(6).DataField = "额定电压D"
Text1(7).DataField = "容量"
Text1(8).DataField = "结线组别"
Text1(9).DataField = "冷却方式"
Text1(10).DataField = "出厂日期"
Text1(11).DataField = "zzg1AB"
Text1(12).DataField = "zzg1AC"
.........
Text1(136).DataField = "J结论"
Set 箱变明细表.DataSource = RS


Private Sub Toolbar1_ButtonClick(ByVal Button As MSComctlLib.Button)
On Error Resume Next
Select Case Button.Index
Case 1
    RS.MoveFirst
Case 2
    RS.MovePrevious
    If RS.BOF Then
       RS.MoveFirst
    End If
Case 3
    RS.MoveNext
    If RS.EOF Then
       RS.MoveLast
    End If
Case 4
    RS.MoveLast

mdb数据库单个表最多256个字段。
我有个数据库有1050个字段，用了5个表

你卡住可能是别的问题，
在卡住的时候暂停运行，看看停在哪里。

Text1(0).DataField = "项目名称"
Text1(1).DataField = "名称"
Text1(2).DataField = "型号"
Text1(3).DataField = "制造编号"
Text1(4).DataField = "制造厂家"
Text1(5).DataField = "额定电压G"
Text1(6).DataField = "额定电压D"
Text1(7).DataField = "容量"
Text1(8).DataField = "结线组别"
Text1(9).DataField = "冷却方式"
Text1(10).DataField = "出厂日期"
Text1(11).DataField = "zzg1AB"
Text1(12).DataField = "zzg1AC"
.........
Text1(136).DataField = "J结论"

你真厉害，写了137条赋值语句。用循环，或自动绑定就可以。

本人是个业余的,怎么自动绑定啊能举例一个吗

能帮我看下添加没问题更新不行

RS.AddNew位置不对，
RS.AddNew，要马上添加数据，然后Update

我试了下不对点Case 6是新建设点Case 7也是新建应该是old = RS.Bookmark没执行。Case 6是添加，Case 7是更新.可能old = RS.Bookmark位置没放对。

[此贴子已经被作者于2022-5-22 19:36编辑过]

now_add是什么用不清楚，但是addnew以后，就是在数据库末尾添加一条空记录。如果执行了addnew，就要对这条记录赋值，然后保存，就有新数据了。
你说case 7是更新，但是没有在这里看到有更新的代码。

6是添加，7是更新，点添加或点更新6就变成确定7就变成取消，我在网上查了下最大可以定义256个，我成定义了136个，我单个做了一个窗体报定义过多。不知原因了。

你这个一个过程写这么多代码，看得眼都花了。
关于录入或更新数据库用循环代码会少些，我把一般的对数据库操作写成函数，程序里调用的话，就只要写两三行就可以完成录入更新等一些常规操作。
当然每个人的习惯用法不一样，  我也是初学的，不一定正确哈，权作参考吧。

我的文本框控件名称都是改成和 数据库内字段 名称一致的。这样方便查找，也方便录入修改等操作。

程序中两句
SQL = "select * from " & MyTable & " where 客户编号= '" & 客户编号 & "'"
Call UPmyData(Me, SQL) '// 修改资料

模块中的函数
'03函数名： UPmyData修改记录
'函数功能： 根据窗体控件中的内容修改一条记录到数据库
'返回    ：
'*****************************************************************************************
Function UPmyData(Myform As Form, SQL As String)
On Error GoTo errmsg
Dim ZD As String, Cont As Object
Opendb (StrDB) '// 这一句是我定义的连接数据库的函数，这里就不展开了
Set RS = CreateObject("adodb.recordset") '//创建一个数据集保存数据
RS.Open SQL, CNN, 1, 3 '//数据集保存数据
For i = 0 To RS.Fields.Count - 1'//循环从库里查询出来的表字段
 ZD = RS.Fields(i).Name'// 把字段名称赋值给ZD
  For Each Cont In Myform.Controls '//循环窗体中的所有控件（这里也可以再加个判断限定文本框）
    If Cont.Name = ZD Then'// 如果控件名字等于字段
    RS.Fields(ZD) = Myform.Controls(ZD)'// 把新值赋给这个字段
    GoTo 222
    End If
  Next
222
Next
RS.Update
Call Msgfrm("修改记录成功", 1, Myform)'//自定义的一个对话框
GoTo 111
errmsg:
    MsgBox Err.Description, , "错误报告"
111
Disconnect'// 自定义的一个断开连接释放内存的过程
End Function

下面的这个是录入函数，也贴一下
