1) MSVC is simply an implementation of C++. If you''re implying that he must use C++, then it isn''t true that he must use MSVC.
2) He said he didn''t know C++, and he wants to do it in Java.
3) I don''t know much Java, but I''m pretty sure that''s possible (I''ve seen Java programs do it before, but I can''t remember what they were).

I''m pretty sure you can''t do that in Java without the use of JNI (and then you ould have to program the native part in C/C++).

There might be a Windows Java library out there that already allows you to do this so have a look. I know JWindows is a MFC to Java binding but I don''t know if it can do what you ask.

Wow, i really wish the name of the forum were larger. Then we wouldn''t get people who know nothing of java give people misinformation as much.

Firstly, I said "not much Java," not "no Java." I say that because I technically know Java, but I know it from its earliest days so not much of it applies anymore.

Secondly, I''ve seen Java programs do that. No, not applets, real Java client side programs. I find it somewhat annoying that you say it''s impossible (and throw in an insult for good measure) when I''ve seen it done.

I don''t think Ross said you couldn''t get a java app to have a icon in the system tray, he is just saying you can''t do it without JNI. I think most of the regulars in the forum are a little tired of C/C++ people posting here without realizing this is a java forum. No offense to you but it has just happened a lot lately.

Maybe it was done using some of Microsoft extensions that come with VJ++, one of this extensions encapsulates the WIN32 api. Keep in mind that rhis extensions makes the program non portable. And I think Microsoft don''t support it anymore.

Please keep in mind that Java is cross platform and you are wanting to do something very Windows specific. There is probably some solution out there like install shield or something that can create and executable that can launch the Java app and add an icon to your tray or something.

2) Is it possible to create "system tray programs" with Java?

There''s an article at the following URL which you might find interesting:

http://www.javaworld.com/javaworld/jw-10-1999/jw-10-jni.html

Here''s the abstract (emphasis mine):

In this article, Tal Liron presents JNI-based design and implementation techniques that can help make your application competitive on all platforms without compromising cross-platform deployment. He provides a full step-by-step tutorial for adding a Windows-specific desktop indicator feature. The tutorial contains an example of attaching native threads to a Java Virtual Machine, plus many generic JNI tips and tricks that even non-Windows programmers may find useful. Likewise, Tal covers design considerations, not just implementation issues, so you don''t have to be a master programmer to appreciate the lessons learned. (4,000 words)
