Crystal 7 Vs 8 on ASP

[welshone]

I have numerous ASP Applications on my server which all use Crystal Reports.
The version 7 ones worked fine until I introduced version 8 reports to a new site.

Does it matter which version of CrystalReports you use on a server. The Server has Crystal 7 installed and all Crystal 8 reports have been saved as 7.

Theoretically, if you've saved your V8 reports as V7 and didn't get any errors, you should be okay.

One test would be to run the "V8 saved as V7" reports through the V7 Crystal Designer on a PC. Brian J. Alves

All reports work when run through the designer.

and when saving the reports from 8 to 7 I get no error messages.


I use SmartViewActiveX.asp and rptserver.asp to create the crystal page.
As long as I have created my site as an application in IIS then this should work, surely ?

<SCRIPT LANGUAGE=&quot;VBScript&quot;>
<!--
Sub Page_Initialize
On Error Resume Next
Dim webBroker
Set webBroker = CreateObject(&quot;WebReportBroker.WebReportBroker&quot
if ScriptEngineMajorVersion < 2 then
window.alert &quot;IE 3.02 users on NT4 need to get the latest version of VBScript or install IE 4.01 SP1. IE 3.02 users on Win95 need DCOM95 and latest version of VBScript, or install IE 4.01 SP1. These files are available at Microsoft's web site.&quot;
CRViewer.ReportName = Location.Protocol + &quot;//&quot; + Location.Host +&quot;/Personnel/rptserver.asp&quot;
else
Dim webSource
Set webSource = CreateObject(&quot;WebReportSource.WebReportSource&quot
webSource.ReportSource = webBroker
webSource.URL = Location.Protocol + &quot;//&quot; + Location.Host + &quot;/Personnel/rptserver.asp&quot;
webSource.PromptOnRefresh = True
CRViewer.ReportSource = webSource
end if
CRViewer.ViewReport
End Sub

I don't know. Perhaps it has something to do with the DLLs used for data access. Maybe the format of the report is V7 but the DLLs that it's looking for are specific to V8. Brian J. Alves

I don't know if this helps but when you install version 8 on a machine you install version 8 of cpeaut32.dll, which is the crystal reports version 8 engine. It over writes version 7. Even if you uninstall 8 and reinstall 7 you still will have the version 8 engine on your system.

If you installed version 8 on your server then it is using crystal reports version 8 engine and your viewer will not work.
