Hoi,

i use the swing/ SWT bridge in order to integrate win32 applications
into a plugin based swing application.

the plugin will be initialised like follows:

		shell = SWT_AWT.new_Shell(getDisplay(), getActiveXCanvas());
		shell.setLayout(new FillLayout());

		// create OLE frame and IExplore control
		oleFrame = new OleFrame(shell, SWT.NONE);
		win32Control = new OleControlSite(oleFrame, SWT.NONE, "Shell.Explorer");
		shell.open();

the content will be loaded when display stuff has been initialised:

		// activate control (OleControlSite 'win32Control' has been created
before)
		win32Control.doVerb(OLE.OLEIVERB_INPLACEACTIVATE);

		OleAutomation anOleControlObject = new OleAutomation(win32Control);
		Variant[] aControlArgList = new Variant[1];
		Variant aControlArgument = new Variant(inId.toString());
		aControlArgList[0] = aControlArgument;
		anOleControlObject.invoke(500, aControlArgList);

		// new: dispose automation object
		anOleControlObject.dispose();

when stopping the plugin the following code will be executed:

		oleFrame.dispose();
		win32Control.deactivateInPlaceClient();
		win32Control.dispose();
		UCSwtUiThread.destroy();
		display.dispose();

adding the new line which disposes the automation object did not affect
the win32 process at all.

how can a variant be disposed by the way?

thanks.

cheers,
chris
