My program is good on OpenCascade 3.0. Unfortunately, I upgrade to 4.0. I got a lots errors. I fix all. It's no error in current. But, the execution get failed. I try using debug step by step. I found it is dead in myApp = new TStars_Application() that is same as myApp = new TSampleOcaf_Application() in SampleOCAF. I just renamed it. I don't get it.
thanks a lot
