GetComponentVersion

The GetComponentVersion function returns a component's version number.

FUNCTION GetComponentVersion (ci: ComponentInstance): LongInt; 

ci

The component instance from which you want to retrieve version information. Your application obtains the component instance from the OpenDefaultComponent or OpenComponent function.

DESCRIPTION

The GetComponentVersion function returns a long integer containing the version number of the component you specify. The high-order 16 bits represent the major version, and the low-order 16 bits represent the minor version. The major version specifies the component specification level; the minor version specifies a particular implementation's version number.
