From: sarwasva on 29 Jul 2006 10:53 Data file and EXE, both are on the Main Memory. Application is having a background thread which does some database operations silently. In one of the article I read that Some times DataReader creates native exception and we are using DataReader in our application.

Anyone having any clue about this exception. It is coming quiet frequently now and am still not able to trace it. Agaain and again it is pointing towards the SQL CE operations but debugging doesn't help because the location is not fixed. sarwasva(a)gmail.com wrote: > Data file and EXE, both are on the Main Memory. > Application is having a background thread which does some database > operations silently. > In one of the article I read that Some times DataReader creates native > exception and we are using DataReader in our application. > > Hilton wrote: > > Are the data files and/or EXE on a card or in main memory? > > > > <sarwasva(a)gmail.com> wrote in message > > news:1154053277.248037.174410(a)75g2000cwc.googlegroups.com... > > > But the the exception is coming even before the application use any > > > P/Invoke.
