Bug? in getDocumentProperty

[abc123abc123]

I do this:
object CurrentPage;
_PdfViewer.GetDocumentProperty(4095 , "Pages.Current",out CurrentPage, 0);

with nearly all pages this works great.
My Document has for example 415 pages. When I´m on page 15 he says CurrenPage=15. Same on page 100: CurrentPage=100.
But when I am on page 415(last page) he says: CurrentPage=414(lastpage -1).

Is there already a solution for this problem



Edit:
When I open the first document, close this and open then a new document i get an comexception. ( {"Ausnahme von HRESULT: 0x82130001"})

Hi, abc123abc123.

Note: the document's property "Pages.Current" contains the zero-based index of page...
So, if you see the last page as current then "Pages.Current" should contain the (<PagesCount> - 1).
and if you see the first page as current - "Pages.Current" == 0.

So:
"Pages.Current" == (<DisplayedCurrentPageIndex> - 1)

Best
Regards.

Oh your right i looked on the wrong part of my code. Sorry

But the 2nd problem in my post still exists. Have you any idea?

The 'current page' in our viewer-control (and in Adobe Acrobat) is the page which is under center-point of pages-view window...
In some cases this rule can give some strange result, especially when zoom is small(<50%) and enabled 'continuous' pages-layout.
Check these moments please...

Also you may give us the detailed, step-by-step instruction - how to reproduce the wrong behavior (the zoom-level, zoom-mode, pages-layout are important).

Here is the .dat file with the settings i use. The menuebar is also disabled.

When I open the first document, close this and open then a new document i get an comexception. ( {"Ausnahme von HRESULT: 0x82130001"})

bei AxPDFXCviewAxLib.AxCoPDFXCview.GetDocumentProperty(Int32 iD, String name, Object& dataOut, Int32 flags)

Could you please give us the exact code that you are using that throws this exception for testing?

In the underlined Line i get the com exception.

I can open a document and than do this as often as i want in this document. When i open the next document and then do this i get an comexception.

Code: Select all

public void CheckButtonState()

I think the reason of your problem is that you use the definite number for document ID.
_PdfViewer.GetDocumentProperty(4095, "Pages.Current",out CurrentPage, 0);

It's incorrect - you must keep the docId from each 'OpenDocument' and use it later... So, the correct code should be:

int docId;
pdfViewer.OpenDocument(<FileName>, ..., out docId, 0);
....
....
pdfViewer.GetDocumentProperty(docId, "Pages.Current", out CurrentPage, 0);

HTH.
