关于水晶报表： vb一运行到那里就自动关闭了。

[TsungLee]

就是这一句
Report.Database.Tables(2).SetDataSource rs2

vb没有报错，就直接关闭了。系统提示，说什么不能读内存。
请高手指教。

反你的代碼帖出來，好象你的代碼有問題？

下面我我調用的一段代碼

Option Explicit

Private Sub Form_Load()
Dim strPathName As String, strReportName As String, strSqlPath As String
Dim rsPath As New ADODB.Recordset
strSqlPath = "select mean from Parameter_tab where parameter_name='tabOrderFormReport'"
rsPath.Open strSqlPath, strPubConnect, adOpenKeyset, adLockReadOnly
If Not rsPath.EOF Then
strPathName = rsPath.Fields(0).Value
Else
MsgBox "§ä¤£¨ì³øªí¸ô®|¡A½Ð»P¸ê°TÁp¨t¡I", vbCritical, "´£¿ô±z"
Exit Sub
End If
strReportName = "custom_tabMaterialGoinReport.rpt"

Screen.MousePointer = 11
Set objReport = objApp.OpenReport(strPathName & strReportName, 1)
' Set objReport = objApp.OpenReport("G:\Report\" & strReportName, 1)
objReport.Database.SetDataSource rsImport
objReport.ReadRecords
CRViewer91.ReportSource = objReport
CRViewer91.ViewReport

Screen.MousePointer = 0

End Sub

Private Sub Form_Resize()
CRViewer91.Top = 0
CRViewer91.Left = 0
CRViewer91.Height = ScaleHeight
CRViewer91.Width = ScaleWidth
End Sub

你这代码是9的版本嘛

我没有用过10.但是8的代码不是这么写的

你应该在写代码的时候就看有没有这个属性出来,而不是招这帖上去

水晶报表9以下版本存在内存泄露的问题

[TsungLee]

改用10.0版本后，问题又变了：
执行到Form2.CRViewer91.ViewReport这里，程序报错“This field name is not known”。我检查过几个字段，都是对应的。这是什么问题呢？


以下是代码片段：
Set Report = CryApp.OpenReport(App.Path & "\" + ReportFile)
rs1.Open "select * from jincang_ordergoods where billnum in (select billnum from jincang_orders where storage " + SQL + ")", cnn
rs2.Open "select billnum,storage from jincang_orders where storage " + SQL, cnn
rs3.Open "select goodnum,amount from xiaoshou_ordergoods where billnum in (select billnum from jincang_orders where storage " + SQL + ")", cnn
Report.Database.Tables(1).SetDataSource rs1
Report.Database.Tables(2).SetDataSource rs2
Report.Database.Tables(3).SetDataSource rs3
Report.DiscardSavedData
Load Form2
Form2.CRViewer91.ReportSource = Report
Form2.CRViewer91.Refresh

Form2.CRViewer91.ViewReport'执行到这里出错
Form2.Show
