In Visual Basic all code is written inside of containers. This video looks at the three essential containers: modules, classes, and structures.
- [Instructor] It's time to write some visual basic code, … often called VB code, so I'll write that in notepad. … Here are some essential rules to follow. … All VB code must live inside a container. … The three containers I'll demonstrate … are modules, classes, and structures. … To create a module, type the word module. … And then the VB has a rule … that says you have to give the container a name, … so I'll call this one FirstModule. … Then move down a line or two, … and you will end this section of code, … this container, with the word End, … and then the type of container that you're closing. … So I'll type in End Module. … Now I'll do the same thing with a class. … I'll type in Class, the name of the class, … go down a line or two, and End the class. … Finally I'll make a structure, … and I'll end it, … the same way we ended the other ones with the word End, … and then the thing that I'm closing, … the container that I'm closing, like that. … Save the file. … And I'll attempt to compile it again. …
