  Hello everyone, I'm an "old timer", because I started learning computer languages in 1974 (!) on a VAX system. (Basic, Fortran IV, Fortran 77, Pascal, Assembler, Cobol, C, C++, ...)

  to jump to VC7 without learning VC6 or its just a compiler difference Of course it's possible. I would even r ecommend that since every new VC version is more in line with the standards than the previous one. I would recommend it too, to directly use the newer VC version! Ignore VC6! I would suggest that if you want to learn Visual C++ that you take a look at the new Visual C++ 2005 Express Ed ...Show All
