From: sarwasva on 27 Jul 2006 18:51 Hi All, I am facing a wired problem in my .net CF application which is written in C#. The application some times shows Native Exception : A native exception has occurred in MyPDAApp.exe. Select Quit and then restart this program or select Details for more information." Selected details and got, "Exception code = 0xc0000005. Exception address = 0x00c79d34. Reading = 0x000004." More info about the application: 1. The application interects with the SQL Server Mobile database as well as with some of the Libraries provided by a middleware. 2. This exception doesn't occure frequently and there is no fixed location in the code where we can trace it. 3. The application exe size is around 1.5 MB 4. SQL Server mobile database .sdf size is around 6MB 5. application is dealing with lots of string operation I read a lot of arlticles on this particular exception but most of them are either pointing towards the SP 3 for .NetCF 1.1 but I am using version 2.0 and Windows Mobile 5 device. Some other articles are pointing towards string operation related problems while P/Invoke. Any help would be highly appreciated. Sarwa
From: " ctacke/>" on 27 Jul 2006 19:05 It's an access violation. Something is using an invalid pointer. I'd look at any P/Invokes first. -Chris <sarwasva(a)gmail.com> wrote in message news:1154040715.249806.255220(a)b28g2000cwb.googlegroups.com... > Hi All, > > I am facing a wired problem in my .net CF application which is written > in > C#.

From: sarwasva on 27 Jul 2006 22:21 But the the exception is coming even before the application use any P/Invoke. Is it possible that some string operation is causing this native exception ? <ctacke/> wrote: > It's an access violation. Something is using an invalid pointer.

Chris, I am setting objects to null, as soon as I am done with it. Is that not enough ? -Sarwa <ctacke/> wrote: > Unlikely.
