Volser Screenshot

Gets the 4-byte 32-bit binary volume serial number of a Windowsdisk drive assigned when it is formatted to provide and almost unique id.Don't confuse this with the volser(, the string name,or the manufacturer's disk serial number assigned to a hard drive at the factory.Uses JNI and C++ native code. Consists of java and JNI you include in your own code. You can test with C: CD \com.mindprod.volser java.exe com.mindprod.volser.Volser and ensuring nativevolser.dll is on the path, e.g. in thecurrent directory. YOU MUST MANUALLY EXTRACTNATIVEVOLSER.DLL and put it on the path. Seehttp://mindprod.com/jgloss/path.html To use getVolser, you need three pieces of code in yourclass:1. an import,2. a static init to load the JNI library3. a call to the getVolser native method i.e. import com.mindprod.volser.Volser; ... static { // get DLL loaded from somewhere on java.library path. System.loadLibrary( "nativevolser" ); // if have troubles change this code to use // System.load( "E:\\com\\mindprod\\volser\\nativevolser.dll" ); /** * test harness * * @param args not used */ public static void main( String[] args ) { // Needs drive letter with colon and trailing backslash final int volser = Volser.getVolser( "C:\\" ); System.out.println( "4-byte Volume serial number for drive C: is " + Integer.toHexString( volser ) ); } } Volser does nothing much by itself, other than a debuggingtest harness to demonstrate getVolser method.
