TypelibMinorVersion Property [Visio 2003 SDK Documentation]
Returns the minor version number of the Visio type library.
intRet = object.TypelibMinorVersion
intRet Integer. The minor version number of the Visio type library.
object Required. An expression that returns an Application object.
The major and/or minor version number of the Visio type library will increase whenever the Visio type library is extended. A program can use the TypelibMajorVersion and TypelibMinorVersion properties to guarantee that the Visio version it is working with provides support for the features it is using.
Small changes to the Visio type library do not affect the Application object's Version property.
