How to know whether the document is modified

[song_sd]

Hi,

As the topic mentioned, I want to know whether the pdf file has been modified by
the PDF-XChange Viewer ocx so that I can make the next decision.
Is there a way?

Hello,

You can check modified flag for document by using next code:

int nActiveDocID = 0;
axCoPDFXCview1.GetActiveDocument(out nActiveDocID);
if (nActiveDocID < 0)
return;
object vDataOut;
axCoPDFXCview1.GetDocumentProperty(nActiveDocID, "Modified", out vDataOut, 0);
if ((int)vDataOut != 0)
MessageBox.Show("Document modified");

Also when this flag is changing you will receive "Documents[#docid].Modified" event. For example you can see how this works in "C#Examples\FullDemo".
