What is the file name extension for visual basic? - vb6

Question

Is it .vb like the latest version, I'm talking about version 6.0 (classic)? I'm trying to properly title a visual basic script for a module I need. If I have to redo a script because I cannot name a extension I am going to be mad.

Answer 1

There are several:
.cls (class file)
.frm (form)
.frx (form - binary information)
.ctl (custom control)
.ctx (custom control binary information)
.vbp (project)
.vbg (project group)
.bas (module)
Probably more...
The one you want is most likely .cls.

Answer 2

From the documentation:
Project File Extensions
Visual Basic produces a number of files when you create and compile a project. These can be categorized as
follows: design-time, miscellaneous development, and run-time.
Design time files are the building blocks of your project: basic
modules (.bas) and form modules (.frm), for example.
Miscellaneous files are produced by various processes and functions of
the Visual Basic development environment: Package and Deployment
Wizard dependency files (.dep), for example.
Design-time and Miscellaneous Files
The following table lists all the design-time and miscellaneous other files that may be produced
when you develop an application:
TABLE 1 (Extension, Description)
.bas Basic module
.cls Class module
.ctl User Control file
.ctx User Control binary file
.dca Active Designer cache
.ddf Package and Deployment Wizard CAB information file
.dep Package and Deployment Wizard dependency file
.dob ActiveX document form file
.dox ActiveX document binary form file
.dsr Active Designer file
.dsx Active Designer binary file
.dws Deployment wizard script file
.frm Form file
.frx Binary form file
.log Log file for load errors
.oca Control TypeLib cache file
.pag Property page file
.pgx Binary property page file
.res Resource file
.tlb Remote Automation TypeLib file
.vbg Visual Basic group project file
.vbl Control licensing file
.vbp Visual Basic project file
.vbr Remote Automation registration file
.vbw Visual Basic project workspace file
.vbz Wizard launch file
.wct WebClass HTML template
Run-Time Files
When you compile your application, all the necessary design-time files are included in the run-time executable files.
Run-time files are listed in the following table:
TABLE 2 (Extension, Description)
.dll In-process ActiveX component
.exe Executable file or ActiveX component
.ocx ActiveX control
.vbd ActiveX document state file
.wct WebClass HTML template
In addition I have seen .vbi used as an "include" file. Basically a .bas module. I'm not sure how common this practice is.
