Crystal Reports works in a 3-tier application ?

[laifuqu]

Anybody knows if Crystal Reports works in a 3-tier application ? where the report would be generated on the middle tier and the report object would then be pushed on to the client that requested.
I am using Crystal Reports 8.5 ActiveX Designer Run Time Library (craxdrt.dll) and VB6. In my server object, I have a methode named "getreport()" that generate and return a object report typed "object". In debug mode, I see object Report generated and returned contains correct data, but the client viewer can not show it. I haven't any error message, only a blank viewer.

thanks for any suggestion.

That should work...

Are you refreshing the data properly?

Thanks for synapsevampire.
I have added "viewer1.refresh" and I have a error message like this : "execution error:'-1247417848(80010108)'. Refresh method of object 'IcrystalReportViewer3' is failed".

What is wrong ?

I am having the same problem. I use VB to create the report and display it. However the data does not change one the report is displayed, closed, and re-entered. By clicking the lightning, it refreshes. However, the user wants it to refresh without doing that.

I tried refresh and get the same error.
Any clues?

Here's the whitepaper examples for using VB:

I ran into this some time ago and futzed around for some time. It should work and it can work, but it can be tricky and it is unstable.

In the end the project got dumped ;-(

Biggest reason was that the RDC (the dev tools in general) are not supported in a distributed environment (aka MTS)

I dug around for you and came up with this.

Funny that when using the RDC and ASP it seems to work (after an update) --

NOTE: bear in mind that the RDC in v8 and 8.5 are virtually the same thing. Nothing major changed. I am not at a machine I can check, but check in the Developer help (CrystalDevHelp.chm) on your system and search MTS. I think there is a note in there.
