I'm running the reverse engineering wizard to go from an Oracle 10g db to classes.
Everything is going fine now up until I try to generate the sources - then I get :


Could not find file 'C:\Users\wblevins\AppData\Local\Temp\RefEmailtype.Telerik.OpenAccess.cs'

Please try again after fixing the problem.

In the "Generate Sources" window.

It is saving everything in the reversemapping.config file

RefEmailtype is one of the oracle tables I'm trying to map...

Hi Bill,

Unfortunately, we were not able to reproduce this behavior. The problem seems to be that the code generator cannot create the source files in the temporary directory. You can try restarting Visual Studio. If this does not help, please create another test project and see if the same thing happens or the problem is only in the current project.

It's happening on any project I create.  I've even tried running Studio 2008 under the Administrator account/credentials/

Does OA need the temp directory to be in a specific place?

The temp dir on this (vista ultimate os) machine is C:\temp

I decided to back up and take a look at your example - but I can't seem to get it running either...

Hey Bill,

Have you checked to see if you have any OpenAccess files in the "C:\Users\wblevins\AppData\Local\Temp\" folder?

There are other  'Telerik.OpenAccess.cs' files for the project I was trying to do there, but not 'RefEmailType'... 

The only 'RefEmailType' file on the machine is at:

c:\Users\wblevins\Documents\Visual Studio 2008\Projects\WebSiteTest\OAlib\Refemailtype.Telerik.OpenAccess.cs

When I tried moving it - the file was deleted from the temp directory and I got the error message again.


I'm going to delete everything and start over again one more time.

Hi Bill,

 Can you send us some more information about your setup - the kind of project on which you are running the Reverse mapping wizard, have you been able to successfully generate the sources for any other class before this?

Can you try switching off partial classes generation via the Options dialog? This could help us in narrowing down the problem.

All the best,
Ady

For what it's worth, I was having the same issue. However, I deleted all of the entity classes that were created, deleted reversemapping.config and app.config, and re-enabled the project to use ORM. I then generated classes without generating partial classes, and it worked.

Hi,

 @Chris - Thank you for the input Chris. There seems to be an intermittent problem while generating the designer class file (<classname>.Telerik.OpenAccess.cs/vb).

We would like to try and determine the reason behind this.

@Bill -
Hi Bill..were you able to progress after removing all files and starting again? If you are still experiencing the error can you send us the information requested in my earlier reply and also your system information (OS,Visual Studio version etc) ? Thanks.

Regards,
Ady
