导航子窗体中的子报表不会在查询更改和重新查询后重新加载

问题描述：

我在导航子窗体中使用多选列表框来定义条件以查询并显示在同一窗体的子报表中的子报表。我正在使用这个询问导航子窗体中的子报表不会在查询更改和重新查询后重新加载

Forms![Main]![NavigationSubform].Form![ETIC By Customer Report].Report.Requery 在整个项目中以这种方式更改报告，它工作得很好，但是当我在事件代码中使用它时，它不会崩溃它只是不更新报告视图。如果我单独打开报告，一切都很好，并适当运作。

Private Sub Command83_Click() 
Dim db As DAO.Database 
Dim qdf As DAO.QueryDef 
Dim varItem As Variant 
Dim strCriteria As String 
Dim strSQL As String 
Dim unitstr As TempVar 
Set db = CurrentDb() 
Set qdf = db.QueryDefs("ETIC by Customer") 
For Each i In [Forms]![Main]![NavigationSubform].[Form]! [Combo11].ItemsSelected 
    strCriteria = strCriteria & "," & Chr(34) & [Forms]![Main]![NavigationSubform].[Form]![Combo11].ItemData(i) & Chr(34) 
    Next i strCriteria = Mid(strCriteria, 2) 
If Len(strCriteria) = 0 Then 
MsgBox "You did not select anything." _ 
, vbExclamation, "Nothing to find!" 
Exit Sub 
End If 
TempVars!unitstr = strCriteria 
strSQL = "SELECT DISTINCTROW DPASDataWorkTable.[Work Order Id], DPASDataWorkTable.[Asset Id], DPASDataWorkTable.[Approval Dt], DPASDataWorkTable.[Item Desc], DPASDataWorkTable.[Work Order Status Cd], DPASDataWorkTable.[Closed Dt], DPASDataWorkTable.ETIC, DPASDataWorkTable.Remarks, DPASDataWorkTable.[Parts Bin Location], DPASDataWorkTable.[Completed Deferred], DPASDataWorkTable.[Floor Technician], LIMSData.[MGMT CD], DPASDataWorkTable.[Date Opened (By W/O)], DPASDataWorkTable.[Remarks For FMA], DPASDataWorkTable.Priority, LIMSData.[MASTER MGT CODE], LIMSData.User, LIMSData.[PRG CAT], LIMSData.UNIT, LIMSData.[VEH MAKE TYPE], LIMSData.Org, LIMSData.Status, LIMSData.Shop, LIMSData.[Physical Location], LIMSData.Driveable, [Concatinated Tasks].[Line Items]," & _ 
"[Concatinated Tasks].[Shop Code], DPASDataWorkTable.[Current Shop], LIMSData.[Physical Location], [MEL Table].[MEL Key], DPASDataWorkTable.[Remaining Hours] AS [Total Remaining], DPASDataWorkTable.[Est Hours] AS [Total Estimated],LIMSData.UNIT As [UNIT]" & _ 
"FROM [MEL Table] INNER JOIN (LIMSData INNER JOIN ((DPASDataWorkTable INNER JOIN [Concatinated Tasks] ON DPASDataWorkTable.[Work Order Id] = [Concatinated Tasks].[Work Order ID]) INNER JOIN DPASDataSubTable ON DPASDataWorkTable.[Work Order Id] = DPASDataSubTable.[Work Order Id]) ON LIMSData.[Local Key] = DPASDataWorkTable.[Local Asset Key]) ON [MEL Table].[MEL Key] = LIMSData.[MEL Key] " & _ 
"WHERE LIMSData.Unit IN (" & strCriteria & ") and DPASDataWorkTable.[Work Order Status Cd]=""O-Open"";" 

Forms![Main]![NavigationSubform].Form![ETIC By Customer Report].Report.Requery 
qdf.SQL = strSQL 
Set db = Nothing 
Set qdf = Nothing 
End Sub

答

我认为你需要切换这两条线：

'update the query (sql) first. 
qdf.SQL = strSQL 
'then requery the form. 
Forms![Main]![NavigationSubform].Form![ETIC By Customer Report].Report.Requery

而且

Forms![Main]![NavigationSubform].Form![ETIC By Customer Report].Report.Requery 
qdf.SQL = strSQL

到

，从MSDN：“如果你不删除TempVar的对象，它会保持直到您关闭数据库为止。在完成使用它们时，最好删除TempVar对象变量。“链接： TempVars。
