roRegistrySection

section to be read or written.

This object must be supplied with a "section" name upon creation.

CreateObject("roRegistrySection", section As String)

Interfaces: ifRegistrySection

The ifRegistrySection interface provides the following:

• Read(key As String) As String: Reads and returns the value of the specified key. Performing Read() on

an entry that does not exist, or on a key within a section that does not exist, will return an empty string ("").

• Write(key As String, value As String) As Boolean: Replaces the value of the specified key.

• Delete(key As String) As Boolean: Deletes the specified key.

• Exists(key As String) As Boolean: Returns True if the specified key exists.

• Flush() As Boolean: Flushes the contents of the registry out to persistent storage.

• GetKeyList() As roList: Returns a list containing one entry per registry key in this section.

Example:

registrySection = CreateObject("roRegistrySection", "widget-usage")

' An empty entry will read as an empty string and therefore be converted to zero.

hits = val(registrySection.Read("big-red-button-hits"))

hits = hits + 1

registrySection.Write("big-red-button-hits", strI(hits))
