Parameters

DriverID  String

ProgID of the device to read from

Name  String

Name of the variable whose value is retrieved

SubKey  String

Subkey from the profile root from which to read the value

DefaultValue  String

Default value to be used if there is no value currently set

Return Value

Name may be an empty string for the unnamed value. The unnamed value is also known as the "default" value for a registry key.

Does not provide access to other registry data types such as binary and double-word.

If a default value is supplied and the value is not already present in the profile store, the default value will be set in the profile store and then returned as the value of the DriverID/SubKey/Name. If the default value is set to null (C#) or Nothing (VB) then no value will be set in the profile and an empty string will be returned as the value of the DriverID/SubKey/Name.
