TStream.ReadComponentRes

TStream

Reads components and their properties from a stream in a Windows resource file format.

function ReadComponentRes(Instance: TComponent): TComponent;

Description

ReadComponentRes is called automatically by the global routine ReadComponentResFile. It can also be called directly if the current position of the stream points to a component written using the WriteComponentRes method.

ReadComponentResFile creates a file stream object, which then calls its ReadComponentRes method.

ReadComponentRes first calls the ReadResHeader method to read a resource header from the stream. If the stream does not contain a resource header at the current position, ReadResHeader will raise an EInvalidImage exception. ReadComponentRes then calls ReadComponent to read the properties that must be set on Instance.
