尝试将Crystal报表导出到HTML文件时，为什么会出现“无法导出报表”错误？

Question

I'm trying to export a Crystal Report to an HTML file, but when I call the Export method, I immediately get this error:

Source : Crystal Reports ActiveX Designer

Description : Failed to export the report.

I have tried both crEFTHTML40 and crEFTHTML32Standard as export format types - and both result in the same error.

Here is a highly simplified version of what I'm doing:

Dim objCRReport As CRAXDRT.Report
[...]
objCRReport.ExportOptions.FormatType = 32 'crEFTHTML40
objCRReport.ExportOptions.DestinationType = 1 'crEDTDiskFile
objCRReport.ExportOptions.DiskFileName = "C:\reportInHtmlFormat.html"
objCRReport.Export False '<--- "Failed to export the report" error here

Please note that I am referencing the "Crystal Reports 9 ActiveX Designer Runtime Library" specifically.

Answer 1

I'm not sure what you have in the [...] section but your code should include a call to open the report with an instance of the CRAXDRT Application.

Dim objCRReport As CRAXDRT.Report

'***********************************
Dim objCRApp As New CRAXDRT.Application

objCRReport = objCRApp.OpenReport("<YOUR REPORT FILENAME>", 1)
'***********************************

[...]
objCRReport.ExportOptions.FormatType = 32 'crEFTHTML40
objCRReport.ExportOptions.DestinationType = 1 'crEDTDiskFile
objCRReport.ExportOptions.DiskFileName = "C:\reportInHtmlFormat.html"
objCRReport.Export False '<--- "Failed to export the report" error here

Answer 2

尝试改为设置HTMLFileName选项：

objCRReport.ExportOptions.HTMLFileName = "C:\reportInHtmlFormat.html"
