水晶报表问题...........
文件 h:\inetpub\wwwroot\JieXiuWebDMIS8\Test\CrystalReport1.rpt 内出错：拒绝访问报表文件。其他程序可能正在使用它。
原来都没问题，前天就是这样了。why?
程序是这样的：
Imports CrystalDecisions.Shared
Imports CrystalDecisions.CrystalReports.Engine
Public Class WebForm3
Inherits System.Web.UI.Page
#Region " Web 窗体设计器生成的代码 "
'该调用是 Web 窗体设计器所必需的。
<System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()
End Sub
'注意: 以下占位符声明是 Web 窗体设计器所必需的。
'不要删除或移动它。
Private designerPlaceholderDeclaration As System.Object
Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init
'CODEGEN: 此方法调用是 Web 窗体设计器所必需的
'不要使用代码编辑器修改它。
InitializeComponent()
End Sub
#End Region
Dim oRpt As New ReportDocument
Dim RCSoft As New ReportClass
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
If Not IsPostBack Then
myForm_Print()
Else
End If
End Sub
Sub myForm_Print()
oRpt.Load(Server.MapPath("CrystalReport1.rpt"))
Dim FilePath As String = "www.pdf"
Dim strFileName As String = Server.MapPath(FilePath)
'RCSoft.ExportToDisk(strFileName, oRpt, 1)
Dim op As New ExportOptions
Dim disk As New DiskFileDestinationOptions
Dim sDate As String
disk.DiskFileName = Server.MapPath("www.pdf") '保存临时路径，自己可以修改
op = oRpt.ExportOptions
op.ExportFormatType = ExportFormatType.PortableDocFormat
op.ExportDestinationType = ExportDestinationType.DiskFile
op.DestinationOptions = disk
oRpt.Export()
Response.ClearContent()
Response.ClearHeaders()
Response.ContentType = "application/pdf"
'Response.ContentType = "application/octet-stream"
Response.WriteFile(disk.DiskFileName)
Response.Flush()
Response.Close()
'System.IO.File.Delete(disk.DiskFileName)
Response.Redirect("www.pdf")
End Sub
End Class

Ensure the filename is correct and the ASPNET account has
permissions to open the file. You can try using the FileStream class to
open the RPT file.Top

出错消息不太正确，你的问题在于这行
disk.DiskFileName = Server.MapPath("www.pdf")
这是输出，你需要给ASPNET账号(或者Network Service账号，如果你用Windows 2003的话)在当前目录写或修改的权限
