Returns the build number for the specified object. Read-only String.
Remarks
If the Application object is specified, the Build property returns the build number of the application. When the System object is specified, this property returns the build number of the operating system. For example, the format used on the About dialog box for an application might look like this: “Version: 4.0.0.xxxx,” where xxxx is the build number of the application. When the Build property for the System object is accessed, it returns the current build of the operating system as you might see used on the Properties page of the System dialog box.
