Thanks

Crude solution if your Java code can run in an applet:

You need IE installed on the same PC.

     1. Use the Web Browser control (SHDOCVW.DLL), insert this into your form.
     2. Make a dummy HTML page which references the applet (just like if you were putting the applet on the web).  Save this as a file.
     3. Use the Navigate function in the Web Browser control to bring up the dummy HTML page.  [it can navigate to local files as well as web sites]

     Incidentally the dummy HTML file can either be distributed with your app, be on a web site somewhere or you can create a local file using the C++ file functions (HTML
     pages are just ASCII text after all)

I would assume that your java classes are not applet.  A neater way will be to use JNI. (Java Native Interface)

I would not quote the example here.  But you can find out further details from the article titled:
