how to generate a qvd file or qvw file from an application in .Net or C or Java

Hello everyone
They need to know how to generate a qvd file or qvw from an application in .Net or C or Java. That is, how to edit the source code of a qvd / qvw?

Thanks for the reply, Rob. My comment that "it's not as easy as you think" was referring to making a dashboard from a set of user generated metrics and KPIs from a BI point of view rather than a technical one.

It's hard enough to generate a useful dashboard from User Specifications as it is, I think!

Good point James. I was also assuming that the OP had some significant tech resources available.

Just of curiosity, what are you doing throug Semantic Web? Are you using some kind of triple-store?

Rob,

I seem to remember that in this community you once wrote about a technique that used QV COM objects to generate an empty QVW from Visual Basic/VBS code. The link that I kept however points to a broken-off discussion, and a community search doesn't return anything that you wrote on this subject.

Any particular reason why this post is gone?

Hi Peter,

I don't recall that specific post. but I have done as you remembered. The API allows for creating documents and it's not very difficult.

Yes it's possible.

I have a java lib which do the job.


It don't have any kind of limitation (number of fields and columns).


I tested it with more than 100 Millions of records and 100 columns - It allows encrypts columns too.


I think that is the best on market - Ralf Becher have a nice solution but not recommend for large dvd's.

Don't agree. My QVD Reader/Writer solution works fine with large data sets!
