我想点击货物编号(textbox)时候,出现一个窗体数据选择,数据选择窗体中有一个datagrid控件,adodc控件,
可是在程序运行时候,sel.Adodc1.RecordSource=sql这句代码总是出错,
提示[ADODC]:没有指定记录源[ADO]:没有为命令对象设置命令

Private Sub 货物编号_Click()

If 货物编号.Locked Then Exit Sub
On Error Resume Next
Dim sel As New 数据选择
Dim sql As String
sql = "select 编号,货物名称,货物类别,货物规格 from 货物信息"
sel.Adodc1.ConnectionString = conn.ConnectionString

sel.Adodc1.RecordSource = sql
sel.Adodc1.Refresh
sel.title = "请选择入库货物"

sel.Show vbModal

If sel.result1 <> "" Then
货物编号.Text = sel.result1
Else
Exit Sub
Unload sel
End If

Unload sel

'更新货名规格与计量单位
MDImain.m_checkado.RecordSource = "select 货物名称,货物规格,计量单位 from 货物信息 where 编号=" + 货物编号.Text
MDImain.m_checkado.Refresh

货物名称.Text = MDImain.m_checkado.Recordset.Fields("货物名称").Value
货物规格.Text = MDImain.m_checkado.Recordset.Fields("货物规格").Value

单位.Text = MDImain.m_checkado.Recordset.Fields("计量单位").Value


End Sub

请大家帮我看看是哪里错误,我查不出来.

conn.ConnectionString '这句.你确定conn.ConnectionString赋值了?...


我写了一下..没有问题的说..添加一个.bas文件,两个Form,分别名为Form1,Form2
.bas文件代码:
Option Explicit

Public dbConn As ADODB.Connection
Public rst As ADODB.Recordset

Public Sub Main()
On Error GoTo errHandle
Dim dbConString As String
dbConString = "Provider=SQLOLEDB;Data Source=127.0.0.1;Initial Catalog=Northwind;User ID=sa;Password=admin"

Set dbConn = CreateObject("ADODB.Connection")
dbConn.ConnectionString = dbConString
dbConn.Open
Form1.Show
Exit Sub
errHandle:
MsgBox Err.Description, vbCritical, "error"
End Sub

Form1代码:
Option Explicit

Private Sub Command1_Click()
Form2.Adodc1.ConnectionString = dbConn.ConnectionString
Form2.Adodc1.CommandType = adCmdText
Form2.Adodc1.RecordSource = "select * from orders where shipName='" & rst.Fields("shipName").Value & "'"
Form2.Show
Set Form2.DataGrid1.DataSource = Form2.Adodc1
End Sub

Private Sub Form_Load()
Set rst = CreateObject("ADODB.RecordSet")
rst.CursorLocation = adUseClient
Dim sql As String
sql = "select * from orders"

rst.Open sql, dbConn, adOpenKeyset, adLockPessimistic, adCmdText

Set DataGrid1.DataSource = rst
End Sub

conn.ConnectionString = "Provider=SQLOLEDB.1;Persist Security Info=False;User ID=sa;Initial Catalog=CMSystem;Data Source=UNT-ZHENG"
conn.ConnectionString 里赋值了
请问.bas文件起什么作用，我没用过

我想在form二里没有ＳＱＬ语句，因为我要多次调用他，所以在别的窗体里给adodc1.recordset赋值

你的Private Sub Form_Load()的form是form1还是form2?

Form1,我写得很清楚..
Form2没有代码.
