Visual Basic 5.0 (released in early 1997) represented a watershed moment. It was the first version that allowed developers to compile真正的 native code (compared to the P-code of VB4), making executables faster and more professional. It also introduced the ability to build ActiveX controls. For a generation of developers, VB5 was the gateway to Windows programming.
