(C) is just an indication of the error from the windows event viewer,
unfortunately there is a bug today where we can't display all the string, this will be corrected in 11.20.SR6
so if you take a look at your windows event viewer, you should see an entry from the QVS starting with C, maybe cannot open file because of .....
There is an error in the windows eventviewer.
He couldn't open the qvw-file. Only, I don't no whe he couldn't open the dashboar. Could it be because he was reloading the data of the dashboard on the server?
I've als an error
"Server: An exception (T) occured during open of xxx.qvw."
These ar most of the time dashboards that are deleted on the server.
But I don't know why he keeps refering to these dashboards.
The T Exception is a new log entry added in QV 11.2 SR4. This release has improved stability with .shared file handling; however, it does not correct pre-existing issues with the .shared file. To correct the existing issues with the .shared file, I recommend creating new .shared files or using the new Shared File Cleaner tool to verify and purge any corrupt objects that the cleaner finds.
Edit: It seems that I am wrong about this. I've been informed of the following: "T or C or O are entries we are copying from the event viewer and the bug is that we are unable to display the string we copy properly." So, please disregard my comment above, and it looks like I have some cleaning up to do on some of these cases.
