Generate code for Property Let / Property Get / Property Set methods

What to use

1. MS Excel worksheet as input / output interface

2. MS Excel VBA macro to generate source code

3. Input parameters

Property Name – External name (used as Property Let / Get name)

Parent Class – Skip. Used in only with delegation (see next post).

Property Type – Variant (V) or Reference (R). Defines whether it’s Property Let or Set.

Internal Prefix – For creation of internal name of the property (E.g. use “p” for “p_X” property name).

External Prefix – For creation of Let / Set parameter name (E.g. use “in” for “in_X” parameter name).

Indent – type required number of Space characters there.

4. Output

After execution of the macro, Code cell will contain generated source code.
