Name-table entries are not used in Windows 3.1. They are supported in Windows 3.0, but they can adversely affect system performance.
The header in a Windows executable file contains a resource table. This table contains data that describes many of the resources in the file. In Windows 3.0, the resource table does not describe named resources or resources that use a type name as a unique identifier. Instead, a name-table structure in the resource table maps a unique integer value to each resource name or type.
Each entry in an executable file's resource table contains a member that identifies the resource type. The decimal value 15 identifies a name-table resource.
