Hi I am facing a problem in a VC 6.0 application. I change the size of a structure by around 28 K and then if I run the system , the system throws up Stack Overflow error. I am not able to understand the reason behind this. Can I change the number of stack frames somehow? Also, I am running Winnt. regards Aashish Suchdev Hughes Software Systems India "DISCLAIMER: This message is proprietary to Hughes Software Systems Limited (HSS) and is intended solely for the use of the individual to whom it is addressed.
