问题描述

嗨
我有一个vb6应用程序，可将特定的晶体导出为pdf格式.我在按钮单击事件中编写了以下代码.

Hi
I have a vb6 application to export a particular crystal to a pdf format. I Wrote the following code in button click event.

Dim crxApplication As CRAXDDRT.Application
Dim oReport As CRAXDDRT.Report
Dim crxExportOptions As CRAXDDRT.ExportOptions
Dim myDatabase As String

Set crxApplication = New CRAXDDRT.Application
Dim crxTable As CRAXDDRT.DatabaseTable

Set oReport = crxApplication.OpenReport(App.Path & "\sample.rpt", 1)
oReport.FieldMappingType = crAutoFieldMapping
For Each crxTable In oReport.Database.Tables
    crxTable.SetLogOnInfo servername, Database, userid, password
Next

Set crxExportOptions = oReport.ExportOptions
crxExportOptions.DestinationType = crEDTDiskFile
crxExportOptions.DiskFileName = App.Path & "\MyReport.pdf"
crxExportOptions.FormatType = crEFTPortableDocFormat
crxExportOptions.PDFFirstPageNumber = 1
crxExportOptions.PDFLastPageNumber = 1
crxExportOptions.PDFExportAllPages = True
oReport.Export False

它工作正常.但是当我单击按钮时，会出现以下警告消息.
数据库文件表名"已更改.继续修改报告！
我验证了水晶报表并保存.直接打开Crystal报表文件时，它可以正常工作.请帮助克服此警告
