Which function is used in VC6.0 ? Is it sprintf() or sprintf_s() ?
If it is sprintf(), then nothing to wonder, becausee sprintfdoesnot check the output buffer size.

sprintf_s(&buffer[offset],offset,"%s",Buffer);

char buffer[12]= {0};
int offset =3;
char Buffer[50] = "Hello World";
sprintf_s(buffer,sizeof(buffer),  "%s", Buffer);
