My scenario is I have a DLL reading and formatting data for a .exe. I keep a record count so when I get a exception, at

ntdll.dll!RtlReportCriticalFailure () Unknown
I insert code if (recordcount == 0x0000196e) __debugbreak; I then start stepping through the code looking for the problem how ever when stepping through the code works I try this multiple times however when I stop the code where the exception were to occur it always complete successfully The listing I am trying to to inset in the richedit is huge about 153 pages 30 lines to page, 134 bytes across I roughly calculate the number of bytes I am trying to insert into the richedit is 1.6 meg.
