I worked through many theories (ByteBuffer, WString, Structure.ByValue, Pointer, etc) but nothing I've tried got me very far with being able to supply a wchar_t into a Structure. I figure that one of the things I've been trying will work if I just get some more implementation details right.

'x' shows as the "tool tip" if I do this:

public static class NOTIFYICONDATA extends Structure { public int cbSize; public HANDLE hWnd; // HWND.setPointer(aJWindow) keeps XP happy, btw! public int uID; public int uFlags; public int uCallbackMessage; public HANDLE hIcon; public char szTip = 'x'; }

But I need to get a bunch of chars into szTip, though. I'll admit to trying char[] and String, but of course that just displayed the pointer related to those objects.

So how to define the szTip?

I found this, and I think it's getting me pretty close to where I want to go:

I don't want to "get" the String so much as "set" it. So here's what I tried:

pnid.szTip = Pointer.createConstant(64L); pnid.szTip.setString(0, "testing tip");

But I got:

This pointer is opaque: opaque@0x40

This might be waaaay off the mark, I know, but my "theory" when stepping out of the world of Java is lacking, so I've been in novice trial and error mode. I've been trying to absorb some of the related recent Jay Walters discussion, but no breakthroughs on getting wchar_t into my structure.

Any advice as a push in the right direction?
