Hi,
I'm trying to control Adobe Acrobat (V.6 or higher), and i want it to show
up in its own window.
Using the following code this works fine so far:

File f = new File("c:\\test.pdf");

Display display = new Display();
Shell shell = new Shell(display);

OleFrame frame = new OleFrame(shell,SWT.NONE);
OleClientSite site = new OleClientSite(frame,SWT.NONE,f);

site.doVerb(OLE.OLEIVERB_SHOW);

But when i now try to set up the Automation Object, just like

OleAutomation auto = new OleAutomation(site);

I get a NullPointerException inside SWT:

Exception in thread "main" java.lang.NullPointerException
at org.eclipse.swt.ole.win32.OleAutomation.<ini
(OleAutomation.java:114)
at Adobe.main(Adobe.java:38)

I checked if site might be null but it isn't (doVerb works so this
shouldn't be the case).

Any idea on this?

Besides, if I try

OleControlSite site = new OleControlSite(frame,SWT.NONE,"PDF.PdfCtrl.6");

instead everthing is fine, but Adobe shows up in my Shell and this turns
out to be rather slow.

Thanks,

Thomas

Thomas,

I would personally just display the pdf in the browser and forget about it.
You can find tutorials on the browser widget as well as pdf viewer on
http://www.zikal.com/

Thanx,
- Kalman
