水晶报表问题，高分相送~~~~~~~~100分

[heiguangbao]

大家好，我现在做了一个网站，在水晶报表中出了问题，请大家帮忙
问题是这样的：
我用强类型定义的水晶报表，同时在WEB.CONFIG中设置了他的数据库路径，通过
程序调用这个路径
可是，现在出现一个问题，就是更改web.config中的数据库，报表的数据没有任何变化，是不是web.config中的路径对报表没有影响呀。
web.config中的原代码是这样的：
<add key="ConnectionDatabaseString" value="Server=APJ007;uid=sa;pwd=;database=SHODATA"/>
水晶报表中的原代码是这样的：
Dim irow As Integer
Dim sPassword As String, sServer As String, sUid As String, sDatabase As String, sConnection As String
Dim clsConnectionInfo As New cConnectionInfo()

sConnection = ConfigurationSettings.AppSettings.Item("ConnectionDatabaseString")
If sConnection.Trim <> "" Then
With clsConnectionInfo
.ConnectionString = sConnection
.resolveConnectionStr()
sPassword = .Password
sServer = .ServerName
sDatabase = .DabaBaseName
sUid = .UID
clsConnectionInfo = Nothing
End With

Else
clsConnectionInfo = Nothing
Exit Sub
End If
'define the parameter about Criticalreport
Dim paramFields As New ParameterFields()
Dim paramField As New ParameterField()
Dim discreteVal As New ParameterDiscreteValue()
paramField.ParameterFieldName = "@category"
discreteVal.Value = Request.QueryString("Category")
paramField.CurrentValues.Add(discreteVal)
paramFields.Add(paramField)
'bind Criticalreport at crystalCritical
Dim Criticalreport As New CachedCritical_Essential()
'Instanziamo la classe e creiamo un nuovo oggetto
Dim credentials As New TableLogOnInfo()


'Completiamo le proprietà con i nostri parametri per l'accesso a SQL
credentials.ConnectionInfo.DatabaseName = sDatabase
credentials.ConnectionInfo.UserID = sUid
credentials.ConnectionInfo.Password = sPassword
credentials.ConnectionInfo.ServerName = sServer

'Aggiungiamo le credenziali al Report Viewer
crystalCritical.LogOnInfo.Add(credentials)
crystalCritical.ParameterFieldInfo = paramFields
crystalCritical.ReportSource = Criticalreport
crystalCritical.DisplayGroupTree = False
crystalCritical.DataBind()

我在做水晶报表时，是直接规定了一个数据库的，现在我想通过web.config中
设定，随时改变路径，请大家帮帮忙！！
