Using Windows' WinHelp in Java

Hello,
I am a new Java programmer wanting to create a Java email application for use ONLY on the Windows platform.  I want to create as part of it a Windows help function using the  WinHelp compiler to create .hlp files.

Question:-
What is the syntax for running a context-sensitive Windows help file from within Java?

I would use the following (apparently) in C:-
WinHelp(hwnd, "c:\myapp\myhelp.hlp", HELP_COMMAND, (DWORD)(LPSTR)"JI(`',`TOPIC_2')")

which loads the indicated Help file and executes the JI() macro to jump to the topic TOPIC_2 within that Help file.

I would much appreciate the Java version of the above.

Thanks,

Trimtrom

Since Java is designed as a platform independent language
and environment, every attempt to e.g.

PlatformA x PlatformB
Win* x Unix

* read directory file lists
new File("c:\documents\joe\") x  new File("/home/joe/doc")
or

* execute program
Runtime.exec("c:\windows\scandisk")   Runtime.vs exec("/bin/rm -rf /tmp/joes")

is a pletform DEPENDENT. So is your problem.

I see the only one solution
Put the C code you mentioned into Java native methods
and do sth like

if( getProperty("os.name").startsWith("Win") {
      // call you native method
      }
else{
      // new BadLuckDialog("Sorry my programs is
      // for Win users only"); {:)
}
Hope it helped
