Access VBA选择子窗体记录使用输入标记更新

Question

我有一个主窗体，上面有按钮，还有一个设置为动态sql语句的子窗体对象。我为子窗体对象的on_exit设置了一个私有子窗体，以获取seltop和selheight。

Private mlngSelTop As Long
Private mlngSelheight As Long
Private Sub frmLists_SubResults_Exit(Cancel As Integer)
'GRAB FIRST AND LAST SELECTED RECORDS
mlngSelTop = Me.frmLists_SubResults.Form.SelTop
mlngSelheight = Me.frmLists_SubResults.Form.SelHeight
End Sub

然后我在那个记录集中做两个循环。第一个检查用户是否选择了1条以上的记录。如果他们这样做了，我会要求他们提供一个标记名称，这样我就可以用自定义标记名称标记所选记录。然后，我再次循环遍历记录集，并为每个项目执行一个动态sql更新语句，以根据记录集ID更新标记列。

这是一个例程，它运行在主窗体上的命令按钮上

Private Sub cmdTagList_Click()
Dim Message, Title, Default, TagListRecs
Dim w As Long
Dim x As Long
Dim y As Long
Dim F As Form
Dim db As DAO.Database
Dim RS As DAO.Recordset
Dim dbu As DAO.Database
Dim RSu As DAO.Recordset
Dim usql As String
Dim fsql As String

Set F = Me.frmLists_SubResults.Form
Set RS = F.RecordsetClone

' Move to the first record in the recordset.
RS.MoveFirst

' Move to the first selected record.
RS.Move mlngSelTop - 1

'LOOP THROUGH SUBFORM RECORDSET FROM SELTOP TO SELHEIGHT AND BUILD COUNT

w = 0
For x = 1 To mlngSelheight
w = w + 1
RS.MoveNext
Next x
RS.Close
Set RS = Nothing
Set db = Nothing

'CHECK COUNT OF SELECTED RECORDS
If w < 2 Then
MsgBox "Please select records from the subform, by selecting 1 record on the left of the row," & vbCrLf & _
"press the shift key and select the last record to be tagged.", vbCritical, "Must Select Records to Tag"

'MULTIPLE RECORDS WERE SELECTED - DO UPDATES
Else
Message = "Please Provide Tag Name:"  ' Set prompt.
Title = "Provide List Name"    ' Set title.
Default = "0"    ' Set default..
TagListRecs = InputBox(Message, Title, Default)
Set RSu = F.RecordsetClone

RSu.MoveFirst

' Move to the first selected record.
RSu.Move mlngSelTop - 1
'CYCLE THROUGH RECORDSET AND RUN UPDATE SQL TO TAG RECORDS SELECTED WITH THE TAG NAME PROVIDED
For y = 1 To mlngSelheight

usql = "UPDATE tblVFileImport SET CallSheet = '" & TagListRecs & "' WHERE ID = " & RSu![ID]

'THIS IS THE LINE THAT ERRORS - RUN-TIME ERROR 91
dbu.Execute usql, dbFailOnError
'THIS IS THE LINE THAT ERRORS - RUN-TIME ERROR 91
RSu.MoveNext
Next y

RSu.Close

Set RSu = Nothing
Set dbu = Nothing

fsql = "SELECT XXX.FIELDS " & _
"FROM XXX "
fsql = fsql & "WHERE NZ(XXX.FIELD1,'') <> '' AND XXX.TAGCOL = '" & TagListRecs & "' "
fsql = fsql & "ORDER BY XXX.FIELD1"

Me.frmLists_SubResults.Form.RecordSource = fsql
Me.frmLists_SubResults.Form.Requery

Me.lblFilter.Caption = "List tagged for " & TagListRecs & ". Copy List to Excel and Have Fun!"
End If
End Sub

有人能帮忙吗？

谢谢！

您在尝试dbu.Execute之前没有Set dbu。。。从而触发"；对象变量未设置">错误(#91(。

在For y = 1 To mlngSelheight之前添加一行Set dbu = CurrentDb
