40 // This class manages properties and their serialization.
41 // What you do is this:
42 // 1. Declare the CProperties object
43 // 2. Call one or more "Add" functions to associate variables with names
44 // 3. Call one of the "Load" or "Save" functions to load or save the values
45 // There are three ways in which the "Load" or "Save" functions operate
46 // a. Loading/saving to/from a file [LoadFromFile/SaveToFile]
47 // In this case the contents of the file will look like
48 // name1=value1
49 // name2=value2
50 // ...
51 // b. Loading/saving to/from a command string [LoadFromCommandString/MakeCommandString]
52 // In this case the contents of the string will look like
53 // -name1=value1 -name2=value2 ...
54 // c. Loading/saving to/from the registry [LoadFromRegistry/SaveToRegistry]
55 // In this case the registry will contain a set of values (name1, name2,...) each of whose
56 // value data is the corresponding value.
