Invalid export DLL or export format

[#1]

I have created a code to export the report to excel and it works.. but when i use the export property of the crystal report viewer, all file format works except for the excel format and I am receiving this kind of message whenever I tried using export property of the crystal report viewer..

"Error in File rpt017 {4742A80B-0356-499C-9B57-BE59A69BD788}.rpt: Invalid export DLL or export format."

any idea? someone?

I've been watching this thread because it discusses the same problem we're having. I'm having trouble figuring out what exactly is needed with the references also. I have tried to create an interop assembly both by adding the reference directly to my project and also by using TLBIMP to create one with the desired name. Neither seems to work for me.

Since ExportModeller.DLL is a COM component, we need an interop assembly that can be called from .NET (ideally a PIA) but I don't see any discussion about how to make this actually work out.

Ken, your issue appears to be quite different from what is being discussed on this thread. The error may be the same, the issue I think is not. Also, this post is geting a bit too long so if only for that reason, it may be better to start a new thread... On the new post please add as much info as possible, including OS, version of CR, etc., etc.

Thank you for your understanding,

Ludek
