| | Microsoft VC compilers are really intended for mediam to large projects. Yes it is pretty complicated to learn, but you can't beat its debugger, object browser, intellsense, and several other features. With single-file programs you will be better off using a simpler IDE like Dev-C++, or a command-line compiler and … |
| | Hummmm -- why don't you just use CString's assignment operator? strcpy() is for C-style character arrays, not c++ classes. The code in that link is incorrect -- you can not pass CString to strcpy() like that. You will stumble across quite a few printing errors like that in books because … |
