Getting Current Page Number (Eclipse RCP/SWT ActiveX)

[jykim]

Hi,

I'm trying to get the current page number from the viewer using the codes below, but have not been successful.
Could anyone please tell me what I'm doing wrong?

Code: Select all

int ptr = OS.GlobalAlloc(OS.GMEM_FIXED | OS.GMEM_ZEROINIT, Variant.sizeof);
short type = OLE.VT_BYREF | OLE.VT_I4;

Variant currPage = new Variant(ptr, type);

automation.invoke(
	getDispatcherId("GetDocumentProperty"), 
	new Variant[] { 
		new Variant(documentId),
		new Variant("Pages.Current"),
		currPage,
		new Variant(0)
	});

int currentPage = currPage.getInt();

Thanks for your help!

It seems like any "GetProperty" methods with "DataOut" parameter are not working.
For example, I was trying to invoke this -

Code: Select all

GetProperty("Commands.Count", DataOut, 0);

with the following codes, but it doesn't work.

Code: Select all

int ptr = OS.GlobalAlloc(OS.GMEM_FIXED | OS.GMEM_ZEROINIT, Variant.sizeof);
short type = OLE.VT_BYREF | OLE.VT_I4;

Variant cmdCount = new Variant(ptr, type);

automation.invoke(
	getDispatcherId("GetProperty"), 
	new Variant[] { 
		new Variant("Commands.Count"),
		cmdCount,
		new Variant(0)
	});

int cnt = cmdCount.getInt();

I'm wondering if the problem is in PDFV AX or in Java/SWT/ActiveX???

Please change your code:

Code: Select all

short type = OLE.VT_BYREF | OLE.VT_I4;

to

Code: Select all

short type = OLE.VT_BYREF | OLE.VT_VARIANT;

Best
