Writing a QVD File

Hi everybody!

I have a tricky situation.

I read a QVD file in the start of my qvw program, and I want to write it again at the end of process. I'm getting an error, because, after I read the file, it's locked py Windows.

Anyone have a clue?

Thanks in advance!

Hi,

Check if any other process is using the QVD. Writing to the QVD errors out only in case of usage by other process.

I agree. Once the QVD has been read, the underlying file is released afaik. If not all classic incremental loads, which are outlined in the reference manual, would not work.

I agree with Martin Mahler and Shruthi Reddy, but when I closed Qlikview I was able to rename the file.

May be check your load script for this may be some source location line have an error while creating the QVD or you can go for QVD maker with another individual QVD Maker for the same QVD.

I executed my routine saving with another name and it worked.

I've noticed that when i re-run my application without closing it the app doesn't work. I need to close my app and run it again.

Thanks everybody!

Yes this problem i am also faced may be go for QVD maker for the QVD and do manipulation there and in another QVW only read the QVD for the reports and chart.

Myself I'm not toally clear of the scenario.  You're loading a dvd then writing to it from within the same qvw or the extracting qvw?

I'm thnking perhaps there's a user options security override checked you may have?
