Most coding standards recommend the use of Hungarian variable naming, which uses prefixes to indicate the variable’s type. However, these naming conventions usually should not be used in a component’s public interface. Consider the following function:

    Public blnCheckStuff(intStuff As Integer) As Boolean

What if you need to change intStuff to a Variant? If you changed the name of intStuff to be consistent with its new type, code using named arguments need to change:

    bResult = blnCheckStuff(intStuff:=1)

So, you would either have to make changes to callers to blnCheckStuff or leave the confusing and inconsistent name alone. Additionally, using Hungarian notation in a public interface betrays implementation details to the outside world, which doesn’t really follow the Encapsulation part of OO.

In most cases, a better approach would be to do a good job documenting your component and use this declaration:

    Public CheckStuff(Stuff As Integer) As Boolean

Users of your component will still be able to tell what types to use by using Intellisense or the Object Browser.
