Invalid Descriptor!!

Hi Experts,

i have a big problem!
I opened an old cr report, i have redefined the link to the table for the report and the subreports. And when i save, the got an error message: Invalid Descriptor (Descripteur non valide). What is the problem? It's impossible to save, and i don't know what cr talk about!

Note:
Version of CR: 8.5 with cr_sp3

thks

Hi frodoman,

this is the Synopsis:

In Crystal Reports (CR) 8.5, a report is connected to a stored procedure through ODBC. The stored procedure is modified, but when the report is refreshed the following error message appears:

"Invalid descriptor index"

But, that message come when i'm trying to save the report not when the report is refreshed...
and i still have the same problem.

bye

I understand you're seeing the error in a different situation but I woudl still advise that you follow the process outlined in this article and see if it corrects the issue.  I no longer have version 8.5 but when I did I would encounter the "invalid descriptor" error in various circumstances but they were always resolved by following this disconnect - reconnect process.

cheers,

What operating system are you using?  8.5 isn't supported and doesn't work very effectively on some O.S.'s

mlmccCommented:
Agree.

In particular XP SP2

Yes i'm using XP SP2... there is a way to fix that problem?!?! upgrade version?!?! :)

frodomanCommented:
Yes, an upgrade to Crystal will work wonders with XP SP2.  You really only need version 9 (which is a HUGE leap from 8.5) but if you're going to make an upgrade there's no reason no to jump right to XI unless you can save money with an earlier version.

Does the report of cr8.5 are going to work with crXI??
0
 
frodomanCommented:
Yes, it should work.  

A word of caution though, it is not backward compatible so once you open and edit a report with crXI you will never again be able to open it with 8.5.  It would be wise to save backup copies of the report(s) somewhere first - that way you can always use 8.5 to open them (maybe on an older operating system) should the need ever arise.

mlmccCommented:
Agree.  I believe any version CR9 or later will work.  Unless you already have CR9 or CR10, the best way would be CR XI.
As forodman stated none of the CR9, 10, or XI are backward compatible to CR8.5 so be sure to have good backups.

In fact... we have crXI, but we hesitate to use it with reports of cr8.5. I have to look for the compatibility of the versions...

frodomanCommented:
You shouldn't have any problem using a report designed in 8.5 in crXI.  Worst case you'll have to open the report in XI to allow it to do format conversions - this is probably not necessary in most cases though.  Again, just make sure you keep a backup just in case you need to use 8.5 for something.

Great! i'll try it...

by the way... i spend a lot of time to look for some programming books or websites about VB6 and CR8.5...
and in a few weeks, we are going to change for VS.Net 2005 and crXI... do you have some books or websites to suggest? thks

frodomanCommented:
Yes.  Check this site: http://www.crystalreportsbook.com/

There's good info on the site.  I have the blue book and used it extensively with VS.Net 2003 and it was a HUGE resource of information that I couldn't find anywhere else.  I'm just in the process of switching to VS2005 myself so I don't know what's changed but I have to believe this book will still be tremendously helpful.

Also you can often find good stuff here and good links as well.  It's not .Net specific but there is some .Net information.
