What is the purpose of CLS files and DLL files in VB?

Does anyone have a good explanation of what the different meaning of the CLS, DLL, and VBP files in a VB project are?

  • CLS file is a class file containing the source code for one class.
  • VBP file is a project file. You open a VBP in the VB6 IDE to browse or edit the code for that project.
  • Projects can also be included in groups (VBG files), roughly equivalent to what .Net calls solutions.
  • DLL file is a compiled executable library built from your VB6 source code. See Wikipedia

The VB6 manual explains many of the file extensions, including CLS and VBP.

In pre .Net days .cls files were where your class modules lived. Dll's stand for Dynamic Link Libraries and is a compiled assembly. VBP stands for Visual Basic Project and is the master file for the whole project.
